METAL BUILDING UNIT.

Application filed October 7, 1919.

To all whom it may concern Be it known that I, Janus DICKSON lVAE-RN, a subject of theKing of Sweden, and a resident of the city of South Melbourne, a suburb of the city of Melbourne, in the county of Bourke, State of Victoria, Commonwealth of Australia, (whose post-oflice address is corner of City Road and Cecil street, in the said city of South Melbourne) have invented certain new and useful Improvements in and Connected with Metal Building Units, of which the following is a specification.

This invention relates to the known type of standardized metal building unit consisting of a triangular metal frame which may be used in various different positions in a building structure whereby a series of such units may be readily fitted together to-form a complete wall and roof frame work. Such units are particularly adapted for the rapid and economical erection of sheds, industrial buildings and like structures, and are usually provided with joint ing or connecting plates which are riveted or similarly attached to the corners of the triangular frame to permit of a series of the units being bolted together to form a complete structure.

The primary object of the present inven tion is to provide a standardized building unit of the above general type, in which special cast anetal junction piecesare cast onto the corners of the triangular frame for the purposes of uniting the side members thereof and connecting the corners of a series of the units .together. Castings are also used to securethe ends of the internal stays of the triangular frame to its side members thus forming a strong and efiicient unit at low cost. The junction pieces are moreover specially shaped to provide a strong and effective interengaging joint between the corners of adjoining units, and

'means are also provided on the unit for supporting the. longitudinal purlins or rafters to which the walls and roof of a building are attached.

Referring to the drawings which form part of this specification Figure 1 is a view of portion of a complete wall and roof framework constructed in accordance with the invention.

Fig. 2 showsthe two sides'of a complete wall and roof framework in which the lower units forming the wall frames are of slightly Specification of Letters Patent.

The invention includes a triangular metal frame having a first side member 2, a second side member 3 and a third side member 1, said members being constructed preferably of wrought iron or steel of desired lengths. The side members 2 and 3 are preferably of T section and the member 1 of tubular section as shown, but metal of other suitable cross section may obviously be employed.

The side members of the unit are united by a right angle junction piece 6, amajor acute angle junction piece 7 and a minor acute angle junction piece 8. Said junc tion pieces are cast onto the ends of the side members preferably by the chill casting process, the ends of the side members being-placed in the metal molds after being; assembled in their proper relative positions.

Extending across the interior of the triangular frame are first and second diagonal stays 9 and 10 which are attached to the frame members 2 and 3 by chill castings at 11 and 12 respectively. A third stay 13 may also be employed as seen in Fig. 2, this stay being attached to the side member 2 by a connecting piece 14 which is cast onto the member 2 and is provided with a lug 16 to receive the lower end of a tie rod 18. Said lug is provided with a pin hole 17 to accommodate a pin 19, whereby the end of the tie rod is held in place as seen in Figs. 9 and 12.

The right angle junction piece 6 is provided with a lug 23 having pin holes 22 and 24. Pins 26 are adapted to connect the ends of tie- rods 2,8 and the upper ends of the tie rods 18 to the right angle junction pieces, while a pin 27 is adapted to connect two of said right angle junction pieces together where they meet at the upper part of the structure as seen in Figs. 1 and 8.

The major acute angle junction piece 7 is provided with a projecting coupling check 29 which is offset to one side of the triangular frame as seen in Figs. 5 and 6. The junction piece 7 is stepped or recessed at the inner or abutting side of the cheek 29 thereby forming a shoulder having an inclined thrust surface 32. The cheek 29 has a lower face 33 which is disposed parallel to the side member 3 or the hypotenuse of the triangle, and is adapted to engage either the inclined thrust surface 32 or the surface 39 (hereinafter described) of an adjoining unit. The cheek 29 is also provided with an end face 34 disposed at right angles to the face 33 and adapted to engage the face 41, (hereinafter described) of an adjoining unit.

The minor acute angle junction piece 8 .is provided with a coupling cheek 36 which is off-set from the plane of the triangular frame niei'ubers 3 and 4 in an opposite direction to that of the check 29. The check 36 is provided with an inclined end face 37 which is disposed parallel to and is adapted to engage the thrust surface 32 of an ad joining unit as seen in Figs. 1 and 4. The junction piece 8 is stepped or recessed on the inner or abutting face of the check 36 thereby forming a shoidder having an upper face 39 which is parallel to the side member 3 and is adapted to engage the face 33 of an adjoining unit as before mentioned and as seen in Figs. 1 and 4. Said shoulder is also provided with a thrust face 41 disposed at right angles to the face 39 and adapted to engage the end face 34 of an adjoining unit as seen in Figs. 1 and 4.

Formed through the coupling cheeks and 36 are coinciding bolt holes and respectively to accommodate holding bolts 42 by which the abutting checks of adjoining units are coupled together as shown.

The junction pieces 7 and 8 are provided with outstanding purlin supports and 44 respectively. Another purlin support 46 outstands from the casting 12 near the middle of the side member 3 as shown. These purlin supports are adapted to carry the wooden purlins or rafters to which the walls and roof of the building are attached.

The minor acute angle junction piece 8 is also provided with flanges 47 which project at both sides of the triangular frame and are provided with bolt holes 48 to ac commodate bolts 49 by which they are secured to a right angle corner piece 51 as seen in Figs. 1 and 13. i

It will be seen from the foregoing that the major and minor acute angle junction pieces are each adapted to interengage with the corresponding junction piece and also the other acute angle junction piece of an adjoining unit, so that a series of the units may be assembled and fitted together as in Figs. 1 and 2. The right angle junction pieces 6 are adapted to receive the tie bars 28 and 18 and also interengage with each other at the center of the roof structure as seen clearly in Figs. .1 and 8.

The tie rods 18 are preferably employed as in Fig. 2 in which case the two lowermost units forming the wall frames may be of larger dimensions than the upper units so that a sufficiently high wall may be formed. In such cases the additional stays 13 and castings 14 are introduced to connect with the tie rods 18 as shown. On the other hand the building frame may be formed of a series of identical units as seen in Fig. 1 in which case the tie rods 18 may be omitted.

In Figs. 16 to 18 a modification particu larly suitable for large units is shown. In this case the second side member 3 of the frame is composed of a series of angle iron bars 55 arranged to form the four corners of a rectangle as clearly seen in Fig. 18. These bars pass through the intermediate casting 12 and their ends extend to a suitable distance inside the junction pieces 7 and 8. Preferably the ends of the two bars which are in line with the coupling cheeks 29 and 36 extend some distance into said cheeks above and below the bolt holes 40, 45. The checks are thus effectively rein forced by the ends of the bars.

The invention provides a cheap, strong and effective standardized building unit and a building frame which may be readily assembled and also dismantled in a minimum of time and without specially skilled labor.
