Description

Technical Field

[0001] This utility model relates to the field of steel structure foundation frame technology, specifically a prefabricated steel structure foundation frame. Background Technology

[0002] A steel frame structure refers to a support system made of steel, whose main function is to support the weight and load of the entire building. It is an important building material applicable to various building types, such as high-rise buildings, industrial plants, and bridges. Steel frames are lightweight and high-strength. They are also used as the foundation frame during foundation construction, significantly improving the foundation's support capacity and seismic resistance. Advantages include improved spatial layout and the use of more energy-efficient and environmentally friendly materials, reducing the amount of building materials used. Currently, steel foundation frames are mostly divided into above-ground and underground sections. The underground section often consists of cast-in-place steel reinforcement supports to facilitate the pouring of foundation piles. During installation, manual on-site tying is often used to connect the various parts of the steel foundation frame, which is time-consuming and slows down construction. Utility Model Content

By using the assembly method to connect the ground components and underground parts of the steel structure foundation frame, the time required for manual on-site binding of the steel structure foundation frame is reduced, the construction speed is accelerated, and work efficiency is improved. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated steel structure foundation frame, including a base plate and a connecting mechanism;

[0005] The base plate consists of six sections. Each section has a tube inserted along the outer edge of its upper surface. Each tube is fitted with cast steel bars. The upper ends of the cast steel bars on the same base plate are vertically slidably connected to a top plate.

[0006] Connection mechanism: Each connection mechanism is installed on the outer arc surface of the top plate. Connecting steel pipes are installed between the connection mechanisms. The steel structure foundation frame ground components are connected to the underground part by assembly, which reduces the time required for manual on-site binding of the steel structure foundation frame, speeds up construction, and helps improve work efficiency.

[0007] Furthermore, the connecting mechanism includes a connecting outer ring and insertion holes. The connecting outer ring corresponds one-to-one with the top plate, and the insertion holes are respectively set on the outer side of the connecting outer ring. A connecting steel pipe is inserted between two insertion holes located on different connecting outer rings and corresponding in horizontal positions, so as to facilitate the connection between the connecting steel pipes.

[0008] Furthermore, the connecting mechanism also includes a limiting pin, which passes through the round hole in the inner wall of the insertion hole and the through hole in the outer arc surface of the connecting steel pipe, respectively, to limit the position of the connecting steel pipe and the connecting outer ring.

[0009] Furthermore, the connecting mechanism also includes an inner connecting ring and bolts. The inner connecting ring is respectively disposed on the upper surface of the top plate, and the outer connecting ring is movably sleeved on the outer side of the inner connecting ring. The bolts pass through the round holes on the surface of the outer connecting ring and are threadedly connected to the screw holes on the surface of the inner connecting ring to connect the outer connecting ring to the top plate.

[0010] Furthermore, each of the cast steel bars is provided with a limiting plate at its upper end. The limiting plate is installed in conjunction with the top plate to restrict the position of the top plate on the cast steel bars.

[0011] Furthermore, it also includes a top support frame, the outer edge of which is provided with a sliding groove, and the connecting steel pipes pass through the interior of the sliding groove to provide support between the connecting steel pipes.

[0012] Furthermore, handles are provided at both ends of the upper surface of the connecting outer ring to facilitate movement of the connecting outer ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This prefabricated steel structure foundation frame has the following advantages:

[0014] In use, the reinforcing steel bars are inserted into the foundation pile casting pit. The bottom and top plates provide support for the upper and lower ends of the reinforcing steel bars, facilitating the casting of the cement foundation pile. Then, the ends of the connecting steel pipes are inserted into the insertion holes until the through holes of the connecting steel pipes coincide with the round holes on the inner wall of the insertion holes. The connecting steel pipes are connected to the connecting outer rings by limiting pins, and the connecting inner rings are connected to the connecting outer rings by bolts.
