Technical Field
[0001] This utility model relates to the field of building materials technology, and in particular to a combined steel truss floor deck structure. Background Technology
[0002] The composite steel truss floor deck structure is a floor structure system widely used in modern construction engineering. It mainly consists of two parts: a steel truss and a floor deck. The two parts are combined and connected by specific connectors, so that each part works closely together to create this efficient and stable floor structure, forming a collaborative whole structure. With its development and progress, it has brought great convenience to the construction industry.
[0003] A search revealed Chinese Patent Publication No. CN207244966U, which discloses a steel truss floor deck and a composite floor deck, applicable to the field of building materials technology. The steel truss floor deck includes a floor deck and a steel truss. The floor deck includes a base plate and first and second extensions located at both ends of the base plate. Both the first and second extensions are parallel to the base plate and extend in opposite directions. The first and second extensions are connected to both ends of the base plate via connectors, which are inclined relative to the base plate. The base plate also has multiple wave crests, which... Reinforcing ribs are provided between the crests and between the crests and their adjacent connectors. A steel truss is fixed to the base plate and includes upper chord steel bars, lower chord steel bars, and steel web members. The steel web members form an isosceles triangle structure. The upper chord steel bars are fixed to the top of the steel web members, and the lower chord steel bars are fixed to the outer sides of the two sides of the steel web members respectively. This utility model has a simple structure and high strength. However, the above structure does not take into account the large volume of the integral structure during transportation, which makes it inconvenient to transport. When the existing structure needs to be disassembled and recycled, it cannot be recycled because the structure is not assembled. Moreover, the assembled structure has insufficient stability and low assembly efficiency, which makes it difficult to meet the usage requirements. Utility Model Content
