Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard processing, in particular to a building steel bar truss template. Background Art

[0002] Rebar truss formwork is a new type of prefabricated concrete formwork for buildings, also known as rebar truss floor decking. It consists of rebar trusses and galvanized steel sheets, joined by resistance spot welding. Fabricated in the factory, rebar truss formwork primarily consists of top and bottom chords and web members, which are joined by resistance spot welding to form the truss structure.

[0003] A Chinese patent application, with publication number CN217734513U, provides a formwork for building steel trusses, comprising a base plate and steel trusses. A steel mesh is embedded in the base plate, and the steel mesh is provided with slots. The steel trusses are arranged in parallel and spaced apart in multiple groups, and the steel trusses are embedded in the slots so that the steel trusses and the steel mesh are snap-fitted. The snap-fitting method makes the steel trusses more convenient to install and effectively reduces construction errors caused by positional offsets. The base plate is cast from concrete and bears external loads together with the cast-in-place concrete floor slab, thus becoming part of the building's floor slab. This avoids the need to remove the formwork, and avoids problems such as holes and gaps in the floor slab left after the formwork is removed after the concrete is poured and formed.

[0004] The above-mentioned formwork has the effect of avoiding dismantling, but in actual application, problems such as uneven floor slabs or loose contact, and difficulty in connecting steel bars will occur. The flatness between the formworks cannot be accurately controlled, and the inserted installation connecting steel bars greatly affects the quality and efficiency of construction. Therefore, it is necessary to provide a building steel truss formwork. Utility Model Content
