Steel bar truss template

Technical Field

The utility model belongs to the field of constructional engineering, and particularly relates to a steel bar truss template.

Background

In the existing laminated slab production process, some templates cannot be prefabricated in factories, pouring is needed on a construction site, and some templates are additionally provided with structures such as steel wire meshes and the like so as to improve the strength of pouring pieces.

In order to further improve the strength of the laminated slab, some manufacturers replace steel wire meshes in the templates with truss ribs, but in the existing templates, each truss rib group is independent, each truss rib needs to be placed independently during factory manufacturing, and forms a steel bar framework consisting of three groups of upper chord steel bars, lower chord steel bars and web member steel bars. Meanwhile, a plurality of steel bars are required to be placed to connect truss ribs during in-situ pouring, and then pouring is carried out, so that the working procedure is complicated.

or the lattice bars are approximately sinusoidal.

Further, the upper chord rib and the lattice rib are welded or bound and connected with the lower chord rib.

The utility model has the positive effects that:

the steel bar truss template can be prefabricated in a factory, the workload of site construction can be reduced, a plurality of truss ribs are connected through the upper transverse ribs and the lower transverse ribs to form a steel bar cage, and pouring operation of the template without dismantling can be performed once when the template is prefabricated.

Meanwhile, the truss ribs, the upper transverse ribs and the lower transverse ribs are all steel bars, and the overall strength of the poured product is higher. The upper chord rib and the lower chord rib which are corresponding to the upper end and the lower end of the lattice rib are protruded, so that the area of the truss rib contacted with the truss rib is larger than that of the traditional truss rib structure when the truss rib is poured with the disassembly-free template, and the overall strength of the steel bar truss template can be further improved.
