The support leg 103 is a detachable part, and can also be integrally formed with the lateral support rib 102 or the vertical support rib 101 , for example, the lateral support rib 102 or the vertical rib is bent to form the support leg 103 . When the supporting feet 103 are detachable parts, they are generally made of non-metallic materials or rust-proof materials, such as plastic materials, cement, sintered bricks, stainless steel, and the like. A spacer 1031 can be installed at the lower end of the integrally formed supporting foot 103 .

As shown in FIGS. 7-8 , the support feet 103 can have various forms. Generally, the support feet 103 are provided with mounting holes 1031, and the lateral support ribs 102 or the vertical support ribs 101 are partially inserted into the mounting holes 1031 and 1031. The support feet 103 are connected or an installation groove ( 1032 ) is provided on one side of the support feet 103 , and the lateral support ribs 102 are snapped into the installation grooves ( 1032 ) to be connected to the support feet 103 . Of course, the mounting groove 1032 and the mounting hole 1031 can be combined, and of course, if it is a metal piece, it can also be connected by welding or screwing.

Two ends of the lateral support rib 102 are respectively connected to a vertical support rib 101 , or the lateral support rib 102 is connected to a plurality of vertical support ribs 101 at intervals, and a vertical support rib 101 is connected to the middle of the lateral support rib 102 . Generally, the detachable steel bar truss floor deck 2 is provided with 2-3 steel bar trusses, so 2-3 vertical support bars 101 can be set on a horizontal support bar 102 to support the upper chord bars 12, which reduces the number of steps and facilitates processing and installation.

Specifically, as shown in FIGS. 4-6 and 9 , the upper end of the vertical support rib 101 is welded and connected to a top chord steel bar 12 , the lateral support rib 102 is connected to two bottom chord steel bars 11 or a plurality of bottom chord steel bars 11 , and the support feet 103 are arranged on The end or middle part of the lateral support rib 102 . Of course, the single-row steel bar truss 1 can also be connected to the support base 10 as shown in Figures 4-6 and 9. For example, the upper chord steel bar 12 and the lower chord steel bar 11 are all welded and connected to the vertical support bar 101, or the upper chord bar 12 is connected to the vertical support bar. The ribs 101 are connected by welding, and the lower chord bars 11 are connected with the transverse support ribs 102 .

The present invention and the embodiments thereof have been described above schematically, and the description is not restrictive, and what is shown in the accompanying drawings is only one of the embodiments of the method of the present invention, which is not actually limited thereto. Therefore, if those of ordinary skill in the art are inspired by it, without departing from the purpose of creation of the present utility model, without creatively designing methods and embodiments similar to this technical solution, all should belong to the protection of the present utility model. scope.
