Description

Technical Field

[0001] The utility model relates to the technical field of building steel profiles, in particular to a steel bar truss assembly-shaped building steel profile. Background Art

[0002] The steel bars in the floor slab are processed into steel trusses, which are then connected to the bottom formwork to form a steel truss formwork. The trusses formed by the steel bars bear the load during construction, and the bottom formwork supports the newly poured concrete. This type of steel truss formwork is commonly found in the construction of steel structure floors.

[0003] For example, the authorization announcement number "CN202047591U" is called a steel truss formwork. Although vertical steel hangers are fixed on the steel truss, and the steel hangers extend out of the bottom formwork, when installing the ceiling, you only need to overlap or connect the ceiling hangers with the steel hangers of the steel truss formwork, which saves time and effort and is easy to operate. However, there are many types of ceilings in decorative ceilings, and the spacing required for the ceiling hangers is different. Once the steel hangers of the steel truss formwork are installed, it is difficult to change the type of ceiling, which causes troubles to the subsequent decoration process. On-site construction often requires flexibility. Therefore, a steel truss assembly is required to form a building steel profile. Utility Model Content
