. jsmaimruanseem diamante The principal objects of the invention are to enable the use of very light sections of structural steel in the arrangements of the floor supports between beams in buildings, to effect a material reduction in the cost of such structures and to provide a structure which will greatly enhance the strength of the entire fabrication.
The principal feature of the invention con sists in rigidly securing a stirrup member to the end of a beam section to rest upon the flange of an adjoining beam section and to form a rigid beam support.
In the drawings, Figure 1 is a perspective view of a main beam of a'building structure showing a pair of joist beams supported therefrom by my improved construction;
Figure 2 is a sectional elevation showing the application of the present invention.
It is desirable in present day building construction to provide floor supports or joists in the form of light rolled I sections and such joists have been supported in loose stirrup structures hung on the main beams. Such construction has certain objectionsboth as to cost and effectiveness and my present invention proposes to greatly simplify the structure and to enhance itsstrength.
The joist beams 1 have secured to their ends a strip of metal, preferably formed from a flat steel bar of a suitable thickness, 3
into the Z-shaped stirrup members 2. The lower right angularly bent end 3 extends under the bottom flange l of the beam 1 and the vertical portion abuts the squared end of the beam while the right angularly turned end 5 extends outwardly and forms a bracket extension which rests upon the top of the flange 6 of the main beam 7 which, as shown in Figure 2, may be encased by concrete 7 and the joists 1 are here shown supporting a floor 7 which may be of concrete.
The stirrup member 2 is rigidly connected to the beam 1 at the bottom flange preferably by having the end edge of the flangedportion 3 secured to the flange 4 by welding forming the joint 3 and the end edge of the top flange 8 of the beam 1' is rigidly connected to the angle of the upright 2 and flange 5 by the welded joint 9.
The joist members may be fabricated as thus described in the shop and when taken to the job are simply dropped into place and properly spaced along the main beams.
They may be used in this manner or the .end'
The advantages to be obtained from a fabrication such as described will be readily apparent to those skilled in the art. Much time will be saved in the placing of the joists and immediately they are properly spaced the securing in position can be effected quite rapidly with the use of an electric or acetylene welder.
It will also be understood that the extremely simple shape of the stirrup members reduces the cost very materially and further, there is no field work required in the assembling or adjusting of parts other than the actual spacing of the joists and the welding of same in position.-
V'Vhat I claim as my invention is: 1. A structural steel fabr1cation,comprising in combination with a beam a metal member formed of Z-shape abutting the end of the beam having one flange extending under the bottom flange of the beam and fused thereto, and the other flange extend ing outwardly from the beam, the abutting end of the top flange of the beam being fused to the outwardly extending flange.
2. A structural steel fabrication, comprisingthe combination with a steel beam section, of a Zshaped member having a web portion abutting the end of the beam section and one flange extending under the beam section and fused along its edge to the lower flangeof the beam section back from the end edge thereof, and a fused joint securing the end edge of the top flange of the beam section to the upper end of the Z-member and integrally uniting the two.
3. A structural steel fabrication, comprising the combination with the main beams of the building, of joist beams arranged transversely between said main beams and Z- shaped 'stirrups having their upper flanges arranged in alignment With the upper joint beam flanges and resting on the upper flanges of the main beams and their under flanges 5 supporting the joists, said Z members being permanently fused at their upper flange ends to the upper flanges of the main beams and permanently fused to the joist members.
4. In a structural steel fabrication, a metal beam, and a metal stirrup member per- 10 manently secured to the end of the beam and having a rigid supporting flange fused to the beam andextending outwardly beyond the end of the beam and forming a rigid, extension therebeyond.
