Description

This technical solution relates to warehouse equipment, in particular to warehouse racks made of metal profiles for warehousing and storage of products. The technical solution can be used in the construction of shelving and in the technology of their manufacture. The rack of this design is designed for use in workshops, garages, basements, sports halls and compact storage rooms.

From the patent documentation, racks are known, each of which contains L-shaped or U-shaped or T-shaped racks in cross section, in the walls of which, along the height of each rack of the rack, hooks are made, mainly in the form of holes, and each rack has beams and each the beam consists mainly of profiles with shelves, stiffeners and hooks, made mainly in the form of protrusions located in the hooks of the racks, while on the beams there are tiered racks (RU 162912 U1, 06/27/2016. SI 2520196 T1, 11/28/2014. KR 101391455 B1, 05/07/2014. KR 101217812 B1, 01/09/2013. SK 12010 U1, 08/09/2010. ES 2157695 A1, 08/16/2001. US 5036778 A, 08/06/1991. EP 0425861 A, 05/08/1991. US 4821649 A, 18.04.1989. US 4607576 A, 26.08.1986. US 4148263 A, 10.04.1979. ITBS 910060 A1, 08.12.1992. IT 1236373 B 25.02.1993).

From advertising publications, racks are known, each of which contains L-shaped racks in cross section with holes in height, angular and end stiffening ribs, as well as shelves with flanges around the perimeter and holes in the flanges, each rack is made of two parts connected by a connector, with the connector and parts of the rack, as well as racks with shelves are bolted together (Internet.Google. Metal rack "Praktik" MS KD 70 × 30 × 185 mm. 2020. https://market.yandex.by/product-metallicheskii-stellazh- praktik-ms-kd).

The "Praktik" rack has racks, each of which in cross section has a semicircular cruelty rib extending outward and semicircular stiffening ribs bent inwardly to the corner, made at the ends of the corner. This rack has a relatively high metal consumption and design complexity, which is associated with the presence of a multitude of bolted connections in the rack, including eight bolts for each connection of the parts of the uprights and three bolts for each connection of the beam to the rack, which is 32 bolts for one tier of the rack. In this case, eight corners are used in the joints of one tier. Bolted connections in racks, corners and bolted connectors predetermine a significant increase in labor intensity for assembling and disassembling racks, as well as for retooling racks in case of rearrangement of a warehouse.

Of the known technical solutions close to the ones presented in this description, there is an analogue - a warehouse rack containing L-shaped racks in cross-section, in the walls of which the lower part is made, longitudinal and transverse beams installed on racks in a tier, on the outer surface of each of which there are hooks in the form of a pair of hooks located in the shaped holes of the racks, and decking located on the beams, and the upper part of each beam is stepwise curved in the vertical and horizontal planes to form an upper stiffener with a lower step on which the deck is located, and the lower part of each beam has the lower stiffening rib bent inside the beam at an oblique angle, while the legs of the hooks with an interference fit are located in the holes of the racks so that in the working position the hooks with their legs are tightly pressed against each other. The hooks are located between the upper and lower stiffening ribs of the beam, each hook is made of a pair of horizontally oriented flat hooks protruding above the front surface of the beam, mirrored relative to each other, and the legs of the hooks are located in the lower narrowed part of the figured hole (RU 162912 U1, 27.06 .2016 - a close analogue).

The analogue has a relatively complex structure due to the fact that a pair of hooks of complex shape is made at each end of the beam, with each hook of the pair located in relation to the other hook so that the legs of the hooks are located in the lower narrowed part of the shaped hole and are tightly pressed against each other. Due to manufacturing errors, the legs of the hooks are not always tightly positioned in the holes of the racks in a position where the hooks are tightly pressed against each other with their legs. As a result, there is a danger when the load from the load on the rack is concentrated on one hook twice the design load. In this case, there is a danger of the hook shearing, which reduces the reliability of the rack.

A significant disadvantage of the analogue is also the fact that the hooks in the form of holes in the racks reduce the bearing capacity of the rack by an amount corresponding to the area of the hole, as a result, in order to maintain the required bearing capacity of the rack, it is necessary to increase the wall thickness of the rack and the metal consumption of the rack.

Another significant disadvantage of the analogue is that in the case of manufacturing conditionally high racks, then from the point of view of transportation of such racks, there are problems of packaging and transportation of racks in one package. Moreover, another problem is that in the case of increasing or decreasing the height of the rack during its operation, it is required to reduce the height of the racks or build them up with other racks and use special means for this.

Of the known racks disclosed in the patent documentation, a close analogue to the rack presented in this description is a modular rack consisting of rectangular in cross-section vertical racks supporting longitudinal and transverse elements (beams) that are attached to the racks and are intended to be placed on them. shelves (decks), while the longitudinal and transverse beams have bending folding tongues (hooks), which are located one above the other and placed in the holes (hooks) of the racks (SK 12010 U1, 08/09/2010 - prototype).

The joints of the beams with the racks of the rack in the prototype do not meet the requirements for the reliability of the rack during its operation due to the unsatisfactory shape of each hook of the rack, which is a window made in the wall of the rack. In this case, each beam has hooks at the end, which are located in the windows of the rack. As a result of such a connection of the beams with the uprights, comparatively large gaps appear in the joints, which reduce the rigidity and stability of the rack. It is also important that through windows in the walls of the rack racks greatly reduce the rigidity of the racks and the bearing capacity of the rack, a decrease in which, as a rule, is compensated by the thickening of the walls of the rack racks and an increase in metal consumption.

The rack disclosed in the prototype does not meet the requirements of its versatility, due to the fact that in the case of a rack changeover to a rack with other dimensions and load-bearing characteristics, the use of other rack racks having a lower or higher height is required. The specified requirement for the versatility of the rack arises from the consumer when it is necessary to readjust the rack when it is necessary to reduce or increase the distance between the floorings in the case of storing cargo or products with other dimensions and weight on them, or in the case of lengthening the rack, or in case of deepening, or increasing the number tiers, or in the case of increasing the height of the rack.

Another problem is that in the manufacture of racks with high racks there is an unsolved problem of packing parts of a rack with high racks in one package with the aim of more efficient and less costly transportation of the rack and its delivery to the consumer in one package.

The common features of this prototype and the rack, which is presented in this description, are such signs that they relate to tiered racks, each of which contains racks made in the form of corners in cross-section with hooks located along the height of the racks, longitudinal and transverse mounted on the racks beams with hooks, which are located on one axis of symmetry above each other at each end of each beam parallel to its end and directed to the lower side, while the hooks of the beams are located in the hooks of the racks, as well as the racking floorings located on the beams.

The technical result of the rack presented in this description is to increase the reliability and versatility of the rack.

The technical result is obtained by the structure of the rack, containing racks made in the form of corners in cross-section with hooks located along the height of the racks, longitudinal and transverse beams with hooks installed on the racks, which are located on one axis of symmetry above each other at each end of each beam parallel to its end and directed to the lower side, while the hooks of the beams are located in the hooks of the racks, as well as the racking floorings located on the beams, and in the upper part of each beam along its entire length there is a curved ledge rounded from above, below which is a continuation of the ledge on which is located flooring between the ledges of the beams, each end of each beam is located at an angle a <45 °, and each post is made of at least two parts connected by a connector, each connector is made with hooks oppositely directed from its middle, which are located in the hooks of the connected parts of the post , and the shape of each hook with the unifier is identical to the shape of each hook of the beam.

On the side of the beam, opposite from the rounded ledge, there is an annular cross-sectional stiffening rib.

The connector in cross section is made in the form of a right angle formed by the walls of the connector, each hook of the connector is formed by a U-shaped notch in the wall of the connector and bending of the middle part of the notch inside the corner of the connector.

Each hook of each part of the post has a rectangular shape in the side view and extends into the corner of the part of the post, and the hook is made by cutting out two parallel horizontal grooves in the post wall with the formation of a bridge between them, bent inwardly at the right angle of the post part.

Each part of the composite strut in the right angle zone is made with an external figured stiffener extending to the outside of the corner, and at the longitudinal edges, each part of the strut has annular cross-sectional stiffeners bent into the inner side of the corner of the strut part.

Parts of each rack in the connected position are butt-butted along the parting line, which is located in the middle of the connector and across it.

On each longitudinal edge of the connector, a semicircular stiffener is made, and in the corner part, the connector has an L-shaped angular stiffener extending into the corner of the connector.

Each hook of the connector and beams has lead-in bevels at the ends.

The parts of the same rack are of the same height.

Parts of the same rack have different heights.

Some parts of one post have the same height, and other parts of this post have different heights.

The longitudinal beams are interconnected by a tie located in the middle part of the rack, and the tie has at each of its ends paired hooks, which are located in the hooks of the longitudinal beam of the rack, while the shape of the tie hooks is identical to the hooks of the longitudinal and transverse beams, and the hooks of the longitudinal beams in shape are identical to the hooks of the racks of the rack, and the screed has upper and lower flanges and the upper flange of the cross member is located in the plane of the longitudinal and transverse beams of the rack, while the flooring of the rack rests on the upper flange of the tie and the flanges of the beams.

The screed hooks in the working position of the rack cover the hooks of the longitudinal beams.

Each wall of a part of the composite post is made with protrusions extending outwardly from the wall.

The drawings show one example of a multi-level rack, which contains longitudinal beams 2 and cross beams 3 mounted on composite racks 1, which are fixed to the hooks of the racks. On beams 2 and 3, there are decks 4 made of metal or solid wood-based panels.

Each rack of the rack is made of at least two upper part 5 and lower part 6 (Fig. 4), connected to each other by the connector 18 described below (Fig. 13-15). If each rack is made from several connected parts, an appropriate number of connectors are used.

In order to evenly transfer loads from the rack to the floor of the warehouse, to avoid distortions of the racks under load, to protect the floor from mechanical damage and to facilitate the movement of an empty rack by sliding on the floor in the event of a warehouse redevelopment, the lower end of each rack of the rack is placed in a plastic thrust bearing 7 (Fig. . 3). Landing of the thrust bearing on the lower end of the rack is carried out with an interference fit in the profiled blind groove 8 of the thrust bearing 7, which ensures reliable fastening of the thrust bearing to the rack.

Each part of the rack in cross section has mutually perpendicular walls 9 and 10 (Fig. 12), each of which has hooks 11 located with a predetermined step along the height of the part of the rack. Each hook 11 is a lug that is rectangular in side view (FIG. 11), with the hook extending inwardly at the right corner of each portion of the strut.

Each hook 11 is made by cutting out two parallel horizontal slots in the wall of the post, followed by bending a part of the metal between the slots inwardly at the right corner of the part of the post, as shown in Fig. 12. As a result, the hook 11 protrudes away from the wall of the rack, which is essential for inserting into its eyelet the hook of the beam, which is described below.

Each part of the composite strut in the area of the right angle is reinforced with a longitudinal external figured stiffening rib 12 (Fig. 12), extending outward from the corner side. Each part of the strut at its longitudinal edges has annular stiffening ribs 13, the shape of which is shown in FIG. 12. Stiffeners 13 have a dual purpose: they increase the rigidity of the racks and increase the safety of personnel during the manufacture and operation of the rack.

At each end of each rack beam, a pair of beam hooks 14 is made (Figs. 7, 10). Each hook 14 is made in the form of a protrusion extending into the lower side of the beam, with the protrusion of each hook located in the plane of the beam. A pair of hooks 14 is located on one axis of symmetry, parallel to the end of the beam and is oriented towards the lower side of the beam with its narrowed lower part. The shape of the protrusion of each hook 14 of the beam is made as shown in Fig. 7, which makes it possible to put the protrusion of the hook 14 on the hook 11 of the rack by inserting the protrusion of the hook 14 into the eye of the hook 11 from top to bottom.

On each beam, along the entire length of the upper longitudinal edge, a figured ledge 15 is made (Fig. 9), limiting the displacement of the flooring 4 of the rack relative to the beams in the longitudinal and transverse directions. At the top, the ledge 15 has a rounded shape. Below the ledge 15, along with it, there is a shelf 16 of the beam, which is a continuation of the ledge 15. The shelf 16 is designed to support the deck 4 on it, which forms the shelf tier, and the shelf 16 is located at an angle to the horizontal within 3-10 ° at an optimal angle of inclination 6.5 ° (Figs. 6 and 9). The end of each flange 16 and step 15 (Fig. 9) of each beam is cut at an angle α≤45 ° as shown in Fig. eight.

On the opposite side of the ledge 15 of each rack beam (Fig. 9), along the lower longitudinal edge, each beam is reinforced with an annular cross-sectional rib 17 stiffening, providing (in addition to rigidity) the safety of service personnel during the manufacture and operation of the rack.

Parts of each composite rack of the rack 5 and 6 (Fig. 16) are connected by a connector 18 (Fig. 13-17). The ends of the parts of the rack are butted together in such a way that one upper part 5 of the composite rack of the rack is a continuation of the lower part 6 of the rack (Fig. 4).

The connector has the shape of an angle (Fig. 15), corresponding to the shape of the connected parts of the rack. The connector has walls 19 and 20 located at right angles to each other with an inner opposite longitudinal angular stiffener 21, with each longitudinal edge of the connector having a semicircular stiffening rib 22. Each wall of the connector has hooks 23 (Fig. 13, 14), oppositely directed from the middle of the wall of the connector to the outer sides and located along the connector.

In the connected position, the parts 5 and 6 of the composite post are joined along the transverse end line 25 of the part apart of the post (Fig. 11, 16). The parting line 25 of the post parts is located in the middle of the connector 18. In the connected position of the post parts 5 and 6, the hooks 23 of the connector (Figs. 13 and 14) are located in the eyelets of the hooks 11 of each part of the composite post, as shown in Figs. 16. Each hook 23 of the connector is located in the window 24 of the connector within this window, while the contour lines of the hook 23 and its side edges do not go beyond the window 24 - they are in the plane of the wall of the connector. Each hook 23 has a shape as shown in FIG. 13 and 14. In each wall of each part of the rack and in each wall of the connector there are technological windows 26 located along the height of the walls.

In a loaded state, a rack is a structure of increased danger due to its possible collapse with a load if the rules for using the racks are violated. In this regard, all the elements of the rack presented in this description are intended both to ensure the bearing capacity of the rack, stability, safety and reliability, and to ensure mobile readjustment of the rack in order to change its parameters using modular unified parts of the rack (racks, beams and decks).

Also, in order to increase safety by neutralizing the axial torques arising in the elongated longitudinal beams of the rack when loading the shelf tiers with cargo, especially in combination with a large depth of the shelf tier, the longitudinal beams of each tier are interconnected by a tie 27 (Fig. 18, 19, 20) connecting the longitudinal beams 2 of the rack in its middle part. For this, at each end of the tie 27, two hooks 28 are made, located parallel to the longitudinal edges of the tie 27 at a distance from each other. The hooks 28 in the working position are located in the lugs of the hooks 29 of the longitudinal beams, and the end of each hook 28 is bent 90 ° away from the adjacent longitudinal beam in order to securely fix the tie in the working position.

Each tie 27 has upper and lower flanges 30 (FIG. 20). The upper shelf 30 of the tie is located in the plane of the shelves 16 of the longitudinal and transverse beams 2 of the rack (Fig. 9) and serves as a support for the rack flooring 4, which, in order to prevent its displacement, is located between the ledges 15 of the beams (Fig. 9).

Each hook 23 of each connector (Fig. 14) has lead-in bevels 31 on the sides, each hook 14 of each beam (Fig. 10) has lead-in bevels 32 on the sides.

To increase the rigidity of each component part of the rack of the rack, each part 5 and 6 of the rack is made with protrusions 33 located as shown in FIG. 3, 11 and 16. Each protrusion 33 has a rounded protrusion on one side of the strut wall, which is equal in height to the strut wall thickness and extends outwardly from the strut wall, and on the other side of the wall, the protrusion has a rounded recess. The protrusions are located with a step between them of 5-7 mm in two mutually perpendicular directions along the entire length of each part of the rack. Extrusions increase the rigidity of each part of the rack, its stability and load capacity of the rack, which is ensured by the creation of a volumetric structure of the wall part, which increases the rack's resistance to bending and has a positive effect on the reliability of the rack during its operation.

The assembly of the rack is carried out in such a way that first the parts 5 and 6 of the racks are connected to each other (Fig. 16). To do this, select the required height of the rack and racks and, in accordance with this height, connect two or more parts of each rack with one or more rack connectors 18 (Fig. 15). On the hooks 23 of one connector 18 (which are symmetrically located on both sides of the transverse axis of symmetry of the connector), hooks 11 of two parts 5 and 6 of one rack are fitted with an interference fit by moving the rack parts towards each other - until the ends of the parts stop against each other. In this case, protruding hooks 23 of the connector are introduced into the lugs of the hooks 11 of the strut parts, which engage with the hooks 11 and the parts of the struts are fixed in a working position, excluding their displacement relative to each other.

Next, a plastic thrust bearing 7 (Fig. 3) is installed with an interference fit on the end of the assembled rack and fixed on the lower part of the composite rack.

Then, a pair of assembled racks is placed on a horizontal flat surface and with an interference fit the hooks 14 of the longitudinal beams 2 (Fig. 2) are inserted into the hooks 11 of the racks. During the assembly process, it is allowed, if necessary, to send hooks 14 of the beams into the eyes of the hooks of 11 racks by tapping with a rubber hammer on the hooks of 14 longitudinal and transverse beams. As a result, a tight and reliable connection of the beams to the rack racks is ensured. The second pair of racks with longitudinal beams 2 are connected in a similar way. The racks assembled in pairs with longitudinal beams are set in a vertical position and the transverse beams 3 are connected to the racks in the manner described above.

It is essential that the hooks of each beam, placed in the hooks of the racks, as described above, ensure the simultaneous subsidence of a pair of hooks of the beam in the hooks of the racks down to their tight interaction, which eliminates backlash in the joints and provides an increase in the stability and reliability of the rack.

The structure of the rack provides for the unhindered entry of each pair of beam hooks into the eyelets of the hooks of the posts, for which each hook of the beam has minimum lead-in tapered edges with bevels, and fixation of each hook of the beam in the eye of the hook of the post is provided, for which the width of each hook of the beam at its base is equal to ( with a plus tolerance) to the length of the rack hook eye. As a result of this design, the reliability of fixing the beams on each rack is achieved and the reliability of the rack is increased.

When installing the rack, each tier of the rack is formed at any height in accordance with the step of placing the hooks on the rack racks and in accordance with the stackable parts of the racks. In this case, each end of each beam, located at an angle of α≤45 °, provides docking of the rack beams located at right angles to each other in the corner zones of the rack, where they converge and dock with each other at a specified angle.

When lengthening or deepening the rack by using longer longitudinal and transverse beams, located in the hooks of the longitudinal beams and bent by 90 ° in the working position, the hooks 28 of the tie (Fig. 20) form stops that exclude the movement of the longitudinal beams to the longitudinal axis of the rack and from the longitudinal axis shelving.

The floorings 4 are laid on the assembled rack frame and the floorings are loaded with a load. In this case, the load is transferred from the flooring to the racks of the rack through the shelves 16 (Fig. 6). Each shelf 16 in an unloaded position, located at a specified angle to the horizontal, sinks under load and takes the operating position shown in FIG. 16. In this case, such errors in the manufacture of floorings such as unevenness of their lower surfaces, leading to stress concentration in individual areas of contact of the flooring with the shelves 16, are compensated for by the downward subsidence in these places of the raised shelves 16. The shelves raised up at the indicated angle in FIG. 9 - under load, in the working loaded position, the racks settle down in places of unevenness of the flooring, which ensures tight contact of the shelves of 16 beams of the shelf with the flooring.

The planks 4 are located on the shelves 16 of the rack beams (Fig. 6) between the ledges 15 of the longitudinal and transverse beams. When upsetting the floorings to the design position, the floorings are wedged between the ledges 15 and all the gaps in the joints of the rack are selected, which has a positive effect on the stability of the rack, its reliability and safety. Since each beam, stepwise bent in the vertical and horizontal planes with the formation of an upper stiffener with a step, excludes the displacement of the flooring without the use of special means for this, this simplifies the design, increases its versatility, reduces the labor intensity of installing the rack, as well as dismantling the rack, which is carried out in reverse order. At the same time, the design allows you to assemble racks of different dimensions from a variety of conditionally short parts of the racks and from a variety of different lengths of beams.

When a loaded rack is in operation, its racks experience bending loads taken by the walls of the rack parts. Since each wall of a part of the composite post is made with protrusions extending outwardly from the wall, due to them, the resistance of each part of the post to bending is increased.

The above technical result is obtained by a combination of essential features of the rack. These features mainly include the design features of the connections of parts of the racks with connectors and connections of racks with beams. The originality of the execution of beams and racks and other features, due to which the laboriousness of assembling and disassembling the racks is reduced and it is possible to assemble different racks from the parts described above in length, depth, height and number of floorings.

The rack of the presented design meets the broader requirements of consumers, expands the choice of a rack of the same model that meets different conditions of its use. The design of the rack meets the requirements for compact packaging of one rack in one package (by eliminating long racks). The design most effectively meets the requirements of storage of racks in packages and transportation of these packages to consumers "from door to door" (from manufacturer to consumer). These advantages are obtained by reducing the dimensions of the rack packaging due to the use of composite racks in the rack design, made of conditionally short rack parts.

The rack provides the ability to store light bulky goods and heavy less bulky goods on it, for which the rack can be easily modified during its operation for the specified types of goods. In the case of a rack modification, the rack racks can be increased by additional rack parts, or vice versa - the racks can be reduced in height, while the number of rack decks can be increased or decreased, and the rack height can be easily reduced by removing the required number of decks and dismantling the upper parts of the racks ... With this modification, the usable area of the warehouse or room can be used as efficiently as possible.

Due to the use of racks, made up of relatively short parts, in the racks, compact packaging of all rack elements in one package, convenient for transportation and storage, is provided, which is transported to the consumer unassembled in one factory package.

The design of the rack meets the requirements for manufacturability of its manufacture, reliability of operation, versatility, convenience of storage, transportation and delivery to the consumer, as well as the requirements for simplification of assembly and dismantling works.

Along with the indicated advantages over known racks, the design of the presented rack can significantly reduce the material consumption of the rack, simplify the process of its manufacture, increase the ability to quickly rearrange the rack from one rack model to another model with other parameters of length, depth, height and number of rack tiers. At the same time, the structure is reliable in operation and more economical in terms of labor costs associated with installation and dismantling works.
