Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a floor deck support of a sheet truss. Background Art

[0002] In the field of construction, truss-supported floor decking is gradually being used in various buildings. For example, in residential buildings, detachable truss-supported floor decking speeds up the construction progress and can be quickly installed. In the existing construction of building steel structures, floor decking is an important load-bearing structure. However, during the construction stage, due to the lack of effective support, the floor decking is prone to deformation and collapse. The existing support device adopts double or multiple rows of round tube scaffolding supports. This type of support is difficult to install and disassemble, and increases the construction cost and time. There is also a method of welding angle steel supports on steel beams. This method increases the welding workload and is only applicable to closed-type floor decks. Therefore, we have introduced a floor deck support with a sheet truss. Utility Model Content
