Description

Technical Field

[0001] This invention relates to the field of floor decking support structures, and more particularly to a suspended steel truss floor decking support structure. Background Technology

[0002] Steel truss floor decking refers to a composite structural system in which the main load-bearing steel bars in the floor deck are prefabricated into steel trusses in a factory, and then the steel trusses are welded together with galvanized steel plates.

[0003] During the floor slab construction phase, formwork is typically not used. Instead, a truss structure formed by welding galvanized steel sheets and reinforcing bars in the structure shares the weight of the concrete floor slab and the construction load. In current building construction, steel truss floor slabs are widely used due to their advantages such as easy installation, rapid construction, and good stress distribution.

[0004] However, during the pouring of large-span floor slabs, if the concrete is not spread in a timely manner, local loads may become excessively concentrated, leading to significant deflection of the galvanized steel sheet and even formwork collapse. Therefore, developing a suspended steel truss floor slab support structure has become an urgent problem for those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a suspended steel truss floor deck support structure to solve the problem that if the concrete is not laid in time during the pouring of large-span floor slabs, the local load may become excessively concentrated, resulting in large deflection of the galvanized steel plate or even formwork collapse.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a suspended steel truss floor deck support structure, comprising a main beam, supports, cables, slings, and a steel truss body. A steel truss body is provided between two adjacent main beams. A galvanized steel plate is provided at the bottom end of the steel truss body, and transverse steel bars are provided at the top end of the steel truss body. A support is provided at the top end of the main beam, and the cables are provided between two adjacent supports. The cables are connected to the transverse steel bars on the steel truss body via slings.

[0007] Furthermore, the upper end of the main beam is provided with a first embedded part, and the lower end of the bracket is provided with a first screw that is threadedly engaged with the first embedded part.

[0008] Furthermore, the top of the bracket is provided with a hook that cooperates with the cable, and the hook is provided with a reinforcing rib that cooperates with the bracket.

[0009] Furthermore, the cable includes a second wire rope and a buckle, the buckle being disposed at the end of the second wire rope, and the second wire rope engaging with a hook on the bracket via the buckle.

[0010] Furthermore, adjacent supports on the same main beam are connected by two diagonal braces; the diagonal braces are bolted to the ear plates on the supports.

[0011] Furthermore, a second embedded part is welded onto the transverse reinforcing bars of the steel truss body; the sling includes a first steel wire rope, a lifting ring, and a second screw, with the second screw located at the bottom end of the first steel wire rope and the lifting ring located at the top end of the first steel wire rope.

[0012] Furthermore, the first wire rope of the sling is connected to the second wire rope of the cable via a shackle; the first wire rope of the sling is connected to the second embedded part on the transverse reinforcing bar via a second screw.

[0013] Furthermore, when the support is located on the side span, the hook at one end of the support engages with the cable, and the hook at the other end of the support is connected to the counterweight; the counterweight is placed on the ground.

[0014] Furthermore, a secondary beam that mates with the bottom end of the steel truss body is provided between two adjacent main beams.

[0015] A construction method for a suspended steel truss floor deck support structure includes the following steps: Step 1: Weld the first embedded part to the main beam and connect the bracket to the first embedded part; Step 2: Pass the transverse reinforcing bars through the steel truss body, weld the second embedded part to the transverse reinforcing bars, and connect the second threaded rod at one end of the sling to the second embedded part; Step 3: Repeat the above steps to complete the installation of another bracket in a supporting structure; Step 4: Pass the shackle at the other end of the sling through the cable, hang the cable on the hook of the bracket, adjust the length of the cable to keep it horizontal, and secure it with the buckle; Step 5: Suspend a counterweight at one end of the side span support to prevent the support from tipping over in the plane. The counterweight is placed on the ground floor. Step 6: Adjacent supports on the same main beam are connected by two diagonal braces to prevent the supports from collapsing out of the plane.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention relates to a suspended steel truss floor deck support structure, which can be used for the construction of steel truss floor decks in high-rise, large-span steel structure buildings. The components are detachable and connectable, facilitating turnover, improving construction efficiency, and saving costs. This suspended steel truss floor deck support structure can be installed and disassembled on the construction floor, avoiding high-altitude work. In summary, this invention's suspended steel truss floor deck support structure is ingeniously designed, functionally practical, and structurally simple. It effectively solves the problem that during the pouring of large-span floor slabs, if concrete is not laid in a timely manner, excessive local load concentration may occur, leading to significant deflection of the galvanized steel sheet and even formwork collapse.
