Description

Technical Field

[0001] This utility model relates to the technical field of floor slab steel truss structure, and in particular to a floor slab steel truss structure. Background Technology

[0002] Steel truss floor slab structures are a type of building structure that combines steel trusses and concrete floor slabs, widely used in multi-story and high-rise buildings. They arose from the need for large spans, lightweight yet high strength, and rapid construction. Traditional concrete structures have limitations in span and construction speed, while pure steel structures, although high in strength, have poor fire and corrosion resistance. Steel truss floor slab structures combine steel trusses with concrete floor slabs, leveraging the high strength and lightweight advantages of steel while utilizing the concrete floor slabs to improve the overall structural rigidity and fire resistance. This structural form is particularly suitable for buildings requiring large spans, rapid construction, and high space utilization, such as stadiums, exhibition halls, industrial plants, and high-rise buildings. With continuous advancements in steel structure design and construction techniques, the application of steel truss floor slab structures in modern architecture is becoming increasingly widespread.

[0003] However, the existing floor slab steel truss structure is not convenient to install between floor slabs and the connection between the floor slab and the steel truss is not flexible enough, which leads to reduced construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a floor slab steel truss structure to solve the problems mentioned in the background art, such as the inconvenience of installation between floor slabs and the lack of flexibility in the connection between the floor slab and the steel truss, which leads to reduced construction efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floor slab steel truss structure, comprising a floor slab, a quick-installation assembly fixedly connected to the top of the floor slab, a steel truss fixedly connected to the top of the floor slab, and a support and vibration damping assembly fixedly connected to one side of the steel truss.

[0006] The quick-installation assembly includes a fixed base fixedly connected to the top of the floor slab, a hollow cylinder fixedly connected to one side of the fixed base, and a rotating column slidably connected inside the hollow cylinder.

[0007] The support and damping assembly includes a support rod fixedly connected to one side of the steel truss, a support seat fixedly connected to the surface of the support rod, and a support column slidably connected to the top of the support seat.

[0008] As a further embodiment of this utility model, a guide pin is fixedly connected to one side of the floor slab, and a fixing pin is fixedly connected to another side of the floor slab. The setting of the fixing pin improves the installation accuracy and efficiency.

[0009] As a further embodiment of this utility model, a fixing buckle is fixedly connected to one side of the rotating column, and a guide column is slidably connected inside the fixing buckle. The setting of the guide column improves the installation accuracy and efficiency.

[0010] As a further embodiment of this utility model, a buckle base is fixedly connected to one side of the fixed buckle, and a movable block is slidably connected inside the buckle base. The movable block enables telescopic movement.

[0011] As a further embodiment of this utility model, a second buckle base is fixedly connected to one side of the fixed base, and a locking buckle is fixedly connected to one side of the second buckle base. The locking buckle serves to lock the base in place.

[0012] As a further embodiment of this utility model, a second support rod is slidably connected inside the support, and a steel truss is fixedly connected to one side of the second support rod. The steel truss serves to provide support and fixation.

[0013] As a further embodiment of this utility model, a damping hydraulic rod is fixedly connected to the bottom of the support column, and a spring is fixedly connected to the surface of the damping hydraulic rod. The spring serves as a buffer.

[0014] This utility model provides a steel truss structure for floor slabs, which has the following advantages:

[0015] 1. This floor slab steel truss structure, through the setting of quick installation components, places the steel truss on the fixed base. The locking buckle and the moving column are interlocked, so that the fixed base and the fixed buckle are closed. The steel truss is fixed by the closure of the fixed base and the fixed buckle. The guide pin and the fixed pin are connected, so that the floor slabs can be quickly connected. This achieves the function of convenient installation and positioning, improves construction efficiency, reduces installation difficulty, ensures the accuracy and stability of the structure, and reduces the workload of personnel.

[0016] 2. This floor slab steel truss structure, through the installation of support and damping components, fixes support rod one and support rod two inside the support. The steel truss is fixedly connected by support rod one and support rod two, so that support rod one and support rod two provide support to the steel truss. By moving the support column downward, the support column drives the damping hydraulic rod to move downward. The downward movement of the damping hydraulic rod achieves a buffering effect, improves the seismic performance of the structure, reduces vibration response, and enhances overall stability.
