UNITED STATES PATENT OFFICE.
f BUILDING STRUCTURE.
Application filed April 9, 1925, Serial No. 21,903, and inGermany May 3, 1924.
In English specification No. 187 ,197 a description is given of fiat or curved structural partitions, such as walls, frame or latticework, roofs and the like, which consists of a number of similar bars or battens crossing each other, which are so arranged that the bars in one direction are secured to each other approximately at the centre of the adjoining continuous bars of the other direction and are in this manner combined to form a network of bars filling a certain space, which network is unyielding to strains in any'dired tion.
In practice these structural partitions, especially for roofs, have hitherto always. been constructed of wood, and endeavours have vainly been made to transfer to practical use the iron construction mentioned as possible in the specification, because such construction has been found to betoo heavy and too expensive when made of iron.
Now according to the present invention this drawback is mitigated due to the fact that for the bars from which the structural part is composed use is made of iron elements of special shape or formation.
The elements found to be suitable for this purpose comprise expanded truss girders which are so formed that in the centre they are able to withstand considerable strain and that they absorb the transverse forces of stresses in an efiicient manner through the binding-pieces or ties.
By the term expanded truss girders is meant girders which are formed by slotting the webs of girders and then expandin the girders laterally causing the slotted we s to expand each into a lattice-work of bracestruts.
In the accompanying drawings a construc-.
tional form of the invention is shown by way of example.
Figure 1 and 2 are elevations ers of suitable form.
Figures 3 and 4 are sections, on a larger scale, ofthe assemblage of three girders at a point of abutment, taken along lines A-A of Fig. 4 and B-B of Fig. 3 respectively.
Figure 5 is a perspective view showing part of a curved hall roof.
The expanded truss girder as shown in Figures 1 and 2 is so formed that it is capable of absorbing a great momentum in the centre and the transverse forces or stresses are extensively taken up by the binding pieces or ties. Expecially suitable for this purpose of two girdis the form, shown in the drawings, with parabolic binding pieces; furthermore also the form with trapezoidal bindingpieces or ties as shown in Figure 2. In order to enable such girders to be combined, in the manner set forth in English specification No.
187 ,197 so as to form individual units :of a skeleton or other structure, the are provided inthe centre with plates 12 eit er riveted or fastened in any other way thereto, which plates carry angle-irons c to which the free ends 6, projecting beyond theties (Z of the other girders tobe connected to the first girders, can be fastened by means of screw bolts, rivets or the like. i
In Figures 3 and lthere is shown upon a larger scale the joint-connection between two girders a and a extendin in the same direction and a girder a exten ing in a transverse direction. The girders a to about the medial part of the continuous girder a The joint-connection between the two girders can, of course, also be efiected in any suitable manner. I
The roof shown in Fig. 5 com rises a beam 9 mounted on supporting bloc s h, several rows of aligned expanded metal girders (1 extending in one general direction, and several rows of aligned similar girders at extending in another direction, the girders a and a being inclined relatively to each other into a curved structure, and the irders a being fixed at their ends to the wei portions of the girders a, and the girders a being fixed at their ends to the web portions of the girders a in the manner described with reference to Figs. 3 and 4.
What I claim is 1. A lattice-work structure for use in constructing roofs, walls, and the like, comprising a plurality of rows of aligned metal girders each consisting of a slotted bar stretched in a direction, perpendicular to its length to give maximum depth at about the mid portions of the girders, a plurality of rows of similar aligned girders extending in another direction, the girders of all the said rows being disposed with the web portions substantially perpendicular to the lattice-work structure, and the girders of each row being fixed with their ends to about the mid portions of the webs of the girders of the rows extending in the other direction, and means for strengthening the mid portions of the girders.
2. A lattice-work structure for use in conand a are secured structing roots, Walls, and the like, comprising a plurality of rows of aligned expanded metal girders extending in one general direction, a plurality of similar aligned girders extending in another direction, all the said girders being disposed with their web portions substantially perpendicular to the lattice- Work structure, strengthening members secured to the Web portions of the girders at about the mid portions thereof, and means for securing the ends of the girders of each row to the said strengthening members secured to the Web portions of the girders of the rows extending in the other direction.
3. A lattice-Work structure for use in constructing root's, Walls, and the like, comprising a plurality of rows of aligned expanded metal gir lers, a plurality of rows oi similar aligned girders extending in another direction, all the said girders being disposed with their Web portions substantially perpendicular to the lattice work structure, and said girders being inclined relatively to each other into a curved structure, and means for strengthening and bracing the said mid portions of the Webs of the girders and for securing thereto the adjacent ends of other girders extending in another direction.
4. A lattice-Work structure for use in constructing roots, Walls, and the like, comprising a plurality of rows 01' aligned expanded metal girders extending in one general direction, a plurality of rows of aligned similar girders extending in another direction, said girders being disposed with their Web portions substantially perpendicular to the lattice-Work structure and being inclined relatively to each other into a curved structure, strengthening members secured to the web portions of the girders at about the mid portions thereof, and means for securing the ends of each girder to the said strengthening members of girders extending in another direction.
5. A lattice-Work structure for use in constructing roots, Walls, and the like, co1nprising a plurality 0t rows of aligned expanded metal girders having the same general. direction, a plurality of similar rows of aligned ex panded metal girders disposed angularly of said first-named rows and in. another general direction, the girders of all the rows being disposed With their web portions substantially perpendicular to the lattice-work structure, plates fixed to the mid portions of the Web portions of the girders, and angle irons fixed to said plates, the girders of the rows having one general direct'on being fixed with their ends to the angle irons ot' the girder ot the rows having another general direction.
In testimony whereof I have aiiixed my sig nature.
