Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete truss floor deck installation and fixing structure. Background Art

[0002] Concrete truss floor deck, also known as truss floor deck or steel truss formwork, is a composite structural system that uses special equipment in the factory to process the main load-bearing steel bars in the floor slab into steel trusses, and then welds the steel trusses with galvanized steel plates to form a whole. This type of floor deck is economical, convenient, safe and reliable, so it has been widely used in the construction field.

[0003] During the construction stage of the structural floor, the truss floor deck uses galvanized steel plates to replace the construction formwork, and the truss structure formed by welding steel bars in the structure bears the self-weight of the floor concrete and the construction load together. After the concrete is poured, the steel truss and concrete are combined to form a whole, and jointly bear the load during the use stage. It adopts a combined structure, making construction more convenient and economical. The truss floor deck has a high bearing capacity and light weight, which can meet the needs of different structural forms. Since the truss floor deck is prefabricated in the factory, its size is accurate and the installation accuracy is high, which can greatly improve the construction efficiency and quality.
