Description

Supporting structure for buildings

The invention relates to shear and tensile load-bearing or support structures for buildings, with pressure-resistant hollow profile-shaped pushers and therein arranged in longitudinal channels with tension tensioned or assembled tensile strands.

In the creation of supporting and supporting structures, it is regularly desirable to be able to choose the height of columns or the span of the carrier as much as possible, so as not to have to accept any restrictions in the architectural design.

In this context, the invention is concerned with the problem of creating such constructions as far as possible from standard parts with production-related maximum dimensions.

From WO 2009/068 687 A1 modules for the production of buildings are known in which between the frame of floor and ceiling slabs columns or posts are arranged, which consist of mutually pinned or bolted squared lumber and have a central longitudinal channel, the one with the frame of the floor and ceiling panels to train or bias associated threaded rod receives. This makes it possible to produce a very stable bond between the floor and ceiling panels.

The object of the invention is now, a particularly easily variable and, if necessary, removable and reusable multifunctional structure or Tragbzw. To create support structure. This object is achieved in that the tension cords are continuously arranged or mounted over a plurality of coaxially abutting poppets, and that are provided between abutting pushers and at the free ends of the abutting pushers transversely to the longitudinal axes of extended metal profiles, wherein in the metal profiles bores to the radial arranged substantially free of play recording the continuous tension cords and the continuous tension cords are anchored or fixed at the free ends of the abutting pushers to the metal profiles arranged there with prestressing, in which case these metal profiles take over the function of tie rods for the tension cords.

The invention is based on the general idea, thrust and tensile load-bearing or supporting structures of any length or height produce by pushing elements together and tensile strength held together by arranged in them tensile cords, wherein the metal profiles are used as tie rods of the tension cords.

By arranged between the abutting push elements and at their free ends metal profiles on the one hand a secure anchoring and on the other hand a good centering of the tension cords is ensured on or in the push elements. In addition, the metal profiles can in principle any, the cross-section of the thrust elements significantly superior size and / or shape and serve to connect in principle any structural parts.

According to a preferred embodiment of the invention, at the end regions of the longitudinal channels of the thrust elements in each case inserted into the longitudinal channels pins or the like, whose cross-section is dimensioned, that the pins are held in the longitudinal channels radially clearance. In addition, these pins have the cross section of the tension strands adapted longitudinal channels, so that the tension cords are also held radially free of play and thus centered in the longitudinal channels of the thrust elements in the pin. If now in the metal profiles of the pull strands interspersed holes whose diameter corresponds at least to the diameter of the tension strands are provided by the pins in conjunction with the tension strands a transversely to the tension strands fixed position of the metal profiles, so that they always a reproducible position taking.

A particular advantage of the invention is the fact that the pushers between the metal profiles can be mounted in multiple-parallel arrangement, in which case the tension cords are optionally arranged only in those pushers on which significant tensile loads are to be expected. In this design, the zugstrangfreien pushers on the metal profiles may optionally be fixed in the transverse direction, that in the metalprofilprofilseitigen ends of the longitudinal channels of these pushers inserted pins are fixed to the metal profiles or are.

The tension cords may optionally be composed of segments of any length, wherein the connecting elements between the segments are preferably formed so that they can be accommodated radially backlash in the respective longitudinal channel of a traversed by the tension cord thrust element.

If, for example, the tension cords are designed as threaded rods, threaded rod segments can be connected to one another by threaded sleeves (with right-hand and left-hand threads), these threaded sleeves having a housing for threaded rods may have a radial clearance recording in the channels sized outside diameter.

A very particular advantage of the construction according to the invention is that in principle any time a dismantling is possible and the previously installed elements can be used to create a new structure.

According to a particularly preferred embodiment, the pusher elements are designed as wooden parts, wherein built wooden parts, which are composed of squared timbers, are particularly preferred. The squared lumber may be pinned together or (preferably screwed with self-tapping screws), so that here in the case of a dismantling standard components for any use are available.

Incidentally, with regard to preferred embodiments, reference is made to the claims and the following explanation of the drawing, are described in detail with reference to the particularly preferred embodiments of the invention. Protection is claimed not only for specified or illustrated feature combinations, but also for any combination of the specified or illustrated individual features.

and 10 possibilities for the construction of shear and tensile loadable space grid arrangements.

FIG. 1 now shows an exemplary cross section of a preferred embodiment of the pusher elements which are provided for the support structure according to the invention. Preferably, each pusher element 1 is assembled using square timbers 2, which are pinned together in the manner shown in Figure 1, wherein for pinning preferably self-tapping screws 3 are used. The square timbers 2 preferably have a cross-section in which the dimensions of the sides of the cross section behave as 2: 1. In particular, the narrow side can have a width of 4 cm and the broad side a width of 8 cm. The arrangement of the screws 3 is only an example, in principle it is also possible to use the screws 3 differently, as shown by way of example in Figure 2. In this way, a thrust element 1 can be produced with a screw-free viewing side V.

In order to avoid a collision of the screws 3, they are used in different transverse planes of the thrust element.

Within the thrust element 1 in the longitudinal direction passing through the longitudinal channel 4, a tensile strand 5 is arranged, preferably in the form of a threaded rod. Instead, pull ropes or the like are possible. According to Figure 3 metal profiles are respectively arranged on the end faces of the thrust element 1, which may be formed, for example. As flange 7 and preferably the Cover entire cross section of the respective thrust element and have a central opening 8, which can be penetrated by the respective tensile strand 5, in the example shown a threaded rod. Thus, the tension cord 5 and the threaded rod can be braced on the respective flange plate 7 by, for example, in the case of a threaded rod, a nut 9 is screwed and clamped against the flange plate.

In order to ensure a centric arrangement of the pull cord 5 and the threaded rod within the longitudinal channel 4 according to a preferred embodiment, can be arranged at the ends of the thrust element 1, that is in the immediate vicinity of the respective flange plate 7 pin-like insertion parts 10, whose cross section corresponds to the cross section of Longitudinal channel 4 is adapted so that the insertion part 10 is received radially backlash within the longitudinal channel. In this case, the cross section of the insertion part 10 may preferably be dimensioned so that the insertion part 10 is held within the longitudinal channel 4 with self-locking. The insertion part 10 has a central bore, which is penetrated by the tension cord 5 and the threaded rod radially clearance.

As a result, the tension cord 5 or the threaded rod is held centrally within the longitudinal channel 4 of the thrust element 1, in which case the tension cord in turn fixes the flange plate 7 transversely to the longitudinal direction of the thrust element 1 in cooperation with the opening 8 in the flange plate 7.

According to Figure 4, several thrust elements 1 can be arranged successively in the longitudinal direction one behind the other, wherein between each two thrust elements 1, a flange plate and at the free ends of the successively arranged thrust elements 1 flange plates 7 'and 7 "are arranged, with only the latter via the continuously arranged tensile strand 5 or as Tension cord used threaded rod under tension of the tension cord 5 are braced against each other. As a result of the tension cord 5 standing to the prestressing, a comparatively high bending stiffness of the thrust element combination is achieved even with closer thrust elements arranged one behind the other.

Incidentally, according to FIG. 5, a plurality of pusher elements 1 can each be arranged parallel to one another, the flange plates 7 then overlapping in each case the cross-sections of a plurality of pusher elements 1 between longitudinally successive pusher elements 1. In such a parallel arrangement of pushers 1, the tension cords 5 can optionally be omitted in "inner" pushers 1, that is, the tension cords 5 are provided in such a construction mainly on outside pushers 1, ie where particularly high tensile stresses can occur zugstrangfreien pushers 1 are preferably on the flange plates 7 each fixedly arranged insertion parts 10 'is provided, wherein the attachment of the insertion parts can be done on the flange plates, for example, with short threaded rod parts, on the one hand enforce an opening 8 of the flange and on the other hand, the longitudinal bores of the insertion parts, said then the insertion parts are clamped with the nuts on the free ends of the threaded rod part turned against the flange plate 7.

FIG. 6 now shows an example of a construction with thrust elements 1 arranged parallel to one another. In particular, it can be seen from FIG. 6 that the pusher elements 1 can be arranged parallel to each other in a basically arbitrary configuration. In addition, Figure 6 shows that on the flange plates 7 instead of the cross section of the tension cords 5 adapted openings 8 and apertures 1 1 may be provided, which are adapted to the cross section of the insertion parts 10, so that each insertion part about half in the longitudinal channels of both adjoining the flange plate 7 arranged thrust elements 1 can be inserted. Optionally, in this embodiment, the insertion parts can also be welded to the flange plate 7 or firmly connected in any other way. Furthermore, it can be seen from FIG. 6 that the flange plate 7 can protrude beyond the cross-sections of the push elements 1 in basically any configuration, so that the flange plates 7 offer the possibility of retaining any structural parts or installations there in principle.

FIG. 7 shows a further example of a construction with thrust elements 1 arranged parallel next to one another. The flange plates 7 each form a rectangular frame plate. The pushers are respectively arranged on the long sides of the frame plate, so that between the pushers 1, a free space 12 remains.

As a rule, it is expedient to arrange a flange plate 7 between longitudinally successive pusher elements 1. However, this is not always necessary. Rather, it is also possible to have two longitudinally successive pushers 1 abut each other directly and to secure the butt joint by the tensile prestress of the longitudinal channels of the two pushers passing through the tensile strand.

Fig. 8 shows an example that between 70 interconnected metal profiles 70 multi-layer parallel thrust elements 1 each form shear and tensile plates 100, which can be combined to tower designs, z. B. for towers of wind power generators or other energy towers. The metal profiles 70 may be formed as U-profiles with horizontal legs, wherein the tension cords of the respective upper plates 100th are anchored on the upper leg and the tension cords of the respective lower plates on the lower leg of the U-profile or are.

9 and 10 show the possibility, in each case a plurality of flange plates 7 to connect to a polygonal connector body 70, so that the connecting body 70 push and pull elements 1, 5 can be connected in different directions and in principle any Raumgitteranordnungen can be created , Notwithstanding the representations in FIGS. 9 and 10, the flange plates 7 forming the connecting body 70 can also be formed similarly to the flange plates 7 in FIGS. 5 to 7, so that in the respective spatial direction to which the respective flange 7 is oriented orthogonally , several, with their longitudinal sides abutting push and pull elements 1, 5 are connectable. Preferably, openings 71 can be formed on the connection bodies 70, through which the interior of the respective connection body is or remains accessible in order to be able to use the nuts 9 or the like for anchoring the tension elements. The insertion parts 10 may be mounted on the respective adjacent flange plate 7 in order to specify the correct connection position of the pushers 1 during assembly of the space grid arrangement. Individual tension elements 5 can also enforce the connecting body 70.

In addition, the connecting body 70 may also be formed as an irregular polygon, for example as a polygonal hemisphere, to connect the interconnected push and pull elements 1, 5 under any predeterminable solid angles with each other or an anchoring point to which the connecting body is connected.
