Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel bar truss floor slab for large-span steel structure construction. Background Technique

[0002] With the development of the national economy, as an important system of prefabricated buildings, prefabricated steel structure buildings are widely used in prefabricated buildings. However, with the change of the application form of steel structure buildings, more and more large-span buildings are emerging, which puts higher requirements on the installation and construction of steel bar truss floor slabs. In terms of installation technology, temporary support, connection design, process monitoring, and data comparison, etc., comprehensive design is required to ensure the construction quality of large-span steel bars in steel structure buildings, and to ensure the convenience, speed, efficiency, and safety of construction at the construction site.

[0003] After retrieval, the prior art (patent application number: 202122024174.X) discloses a steel bar truss floor slab, which includes a bottom formwork and a plurality of steel bar truss units. The steel bar truss units are arranged side by side on the bottom formwork. Each steel bar truss unit includes a support and web bars. The web bars are respectively fixedly connected to the support and the bottom formwork. The support includes two vertical rods and at least two diagonal rods. The two vertical rods are arranged side by side. One end of each diagonal rod is fixedly connected to the bottom formwork, and the other end of at least one diagonal rod is fixedly connected to one vertical rod, and the other end of the remaining diagonal rods is fixedly connected to the other vertical rod. The diagonal rods are used to make the middle of the bottom formwork arch. The steel bar truss floor slab of the utility model can reduce the construction amount and shorten the construction period while realizing the support. The inventor found the following problems in the process of realizing the utility model:

[0004] Such steel bar truss floor slabs have poor functionality. They make the middle of the bottom formwork arch through diagonal rods, achieving a certain support effect and reducing the construction amount and construction period. However, their design has deficiencies in seismic performance and overall structural stability. There are no special shock absorption measures, so that the structure may be greatly impacted when facing external forces such as earthquakes. At the same time, the connection method between the bottom formwork and the steel bar truss unit may not be firm enough, affecting the bearing capacity and safety of the overall structure. In addition, for large-span structures, this design may be difficult to provide sufficient support and stability, limiting its application scope in large-span steel structure construction.

[0005] Therefore, a steel bar truss floor slab for large-span steel structure construction is proposed to solve the above problems. Content of the Utility Model
