Description

Technical Field

[0001] The present application relates to the technical field of steel structures, and in particular to an assembled steel structure building. Background Art

[0002] Prefabricated steel structure buildings are prefabricated buildings whose structural system is mainly composed of steel parts. It has many advantages, such as fast construction speed, high installation quality, light weight, low foundation cost, recyclable materials and green environmental protection. In addition, as a ductile material, steel structure has excellent seismic resistance. However, prefabricated steel structure buildings also have some disadvantages, such as the difference between the exterior wall system and traditional buildings, the need to pay attention to fire prevention and anti-corrosion issues, and the possibility of high costs in some cases.

[0003] According to different application fields and structural systems, prefabricated steel structure buildings can be divided into large-span space steel structures, low-rise light steel structures, multi-story and super-high-rise steel structures, etc. These structural systems are widely used in various fields such as stadiums, exhibition centers, terminals, hangars, industrial plants, warehouses, supermarkets, residential and public buildings.

[0004] In terms of construction, in order to ensure the stability and normal use of prefabricated steel structure buildings in outdoor environments, they usually need to be fixed to the ground. The traditional fixing method is to use concrete to harden the ground and directly connect the building's supporting structure to the concrete for solidification to achieve stable support. Although this fixing method can provide strong stability, it requires the concrete and supporting structure to be broken when the steel structure building is dismantled and transferred, which reduces construction efficiency and is prone to damage the supporting structure, affecting the utilization rate of the device.

[0016] By adopting the above technical scheme, by setting up the coordinated use of the adjustment component and the support rod, it is convenient to drive the support rod along the length direction of the sleeve rod by rotating the adjustment component to drive the grounding plate to contact the ground, and then pass the fixed steel fork through the grounding hole and fix it in the ground, so that the steel structure building body cooperates with the sleeve rod, support rod, grounding plate, fixed steel fork and the ground to form a stable triangular support structure, thereby further improving the supporting strength of the steel structure building body and improving the stability of the device.

[0035] Furthermore, an unlocking spring 15 is symmetrically fixedly connected inside the inner slide groove 12 , and one end of the unlocking spring 15 is fixedly connected to the moving slide plate 13 .

[0036] When in use, firstly, a foundation groove for pouring concrete piles 1 is dug on the ground, then the L-shaped connecting plate 2 is placed on the top of the poured concrete piles 1, and one end of the expansion bolt 5 is inserted into the fixing hole 4 through the insertion hole 3, and at the same time, the expansion bolt 5 drives the L-shaped connecting plate 2 to form a fixed connection with the concrete pile 1, and the top of the expansion bolt 5 is inserted into the receiving groove 6, and then the bottom plate 11 is placed on the top of the L-shaped connecting plate 2 by pulling, and then the unlocking spring 15 is squeezed along the length direction of the inner slide groove 12 by pushing the moving slide plate 13 to produce a contraction shape. The movable slide plate 13 drives the guide slide bar 14 to push the pressing plate 8 to the top of the bottom plate 11, and then the locking nut 10 is tightened to push the pressing plate 8 along the length direction of the threaded rod 7 to form a tight contact with one end of the bottom plate 11, so that the bottom plate 11 is clamped by the pressing plate 8 and the L-shaped connecting plate 2 and fixed to the top of the L-shaped connecting plate 2, and at the same time, the bottom of the bottom plate 11 is mounted above the storage groove 6 and forms a conflict with the top of the expansion bolt 5, thereby reducing the situation where the expansion bolt 5 is loose and pushed out of the storage groove 6;

[0037] Then, when it is necessary to release the interference of the pressing plate 8 with the base plate 11, the locking nut 10 is loosened to release the interference of the locking nut 10 with the pressing plate 8 along the length direction of the threaded rod 7, and at the same time, the pressing plate 8 is released from the interference with the base plate 11, and then the unlocking spring 15 is released from the force, and the movable slide plate 13 is ejected along the length direction of the inner slide groove 12, and at the same time, the movable slide plate 13 drives the guide slide rod 14 to pull the pressing plate 8 along the length direction of the inner slide groove 12 to separate from the top of the base plate 11, so as to facilitate the rapid driving of the pressing plate 8 to separate from the interference with the base plate 11, thereby improving the practicability of the device.

[0042] Furthermore, angle steels 26 are fixedly connected to the four corners of the steel structure building body 17 , and two ends of the abutment plate 18 are fixedly connected to two angle steels 26 , respectively.

Then, when encountering strong winds, the sleeve rod 19 is rotated around the hinge axis to drive the support rod 20 to guide the ground plate 21 to rotate toward the ground. Then, the adjusting screw sleeve 24 is rotated to cooperate with the adjusting thread groove 25 to form a threaded connection with the support rod 20, and the support rod 20 is pushed to move along the length direction of the sleeve rod 19.

[0047] Then, when it is necessary to release the interference of the pressing plate 8 with the bottom plate 11, the locking nut 10 is loosened so that the locking nut 10 releases the interference with the pressing plate 8 along the length direction of the threaded rod 7, and the pressing plate 8 releases the interference with the bottom plate 11, and then the unlocking spring 15 is released from the force, and rebounds along the length direction of the inner slide groove 12 to push out the moving slide plate 13, and at the same time, the moving slide plate 13 drives the guide slide rod 14 to pull the pressing plate 8 along the length direction of the inner slide groove 12 to separate from the top of the bottom plate 11;

[0048] Then, when encountering strong winds, the sleeve rod 19 is rotated around the hinge axis to drive the support rod 20 to guide the ground plate 21 to rotate toward the ground, and then the adjusting screw sleeve 24 is rotated to cooperate with the adjusting thread groove 25 to form a threaded connection with the support rod 20, and the support rod 20 is pushed to move along the length direction of the sleeve rod 19, while the support rod 20 drives the ground plate 21 to form a contact with the ground, and then one end of the fixed steel fork 23 is pulled through the grounding hole 22 and inserted into the ground, so that one side of the steel structure building 17 cooperates with the sleeve rod 19, the support rod 20, the ground plate 21, the fixed steel fork 23 and the ground to form a stable triangular support structure, thereby further improving the supporting strength of the steel structure building 17.
