Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and specifically to a prefabricated steel structure for buildings. Background Technology

[0002] In the field of modern architecture, prefabricated buildings are gradually becoming the mainstream development direction. Among them, prefabricated steel structures have attracted much attention due to their unique advantages. With the acceleration of urbanization, the construction industry faces the urgent need to improve construction efficiency, ensure building quality, and achieve sustainable development. Traditional construction methods have problems such as long construction cycles, a lot of on-site wet work, and serious waste of resources, which can hardly meet the fast-paced construction needs of modern society. Prefabricated steel structures have emerged to meet these needs. They combine the high strength and lightweight characteristics of steel structures with the advantages of industrialized production and rapid on-site assembly of prefabricated buildings, bringing new development opportunities to the construction industry.

[0003] According to the public announcement (CN220266897U), a prefabricated steel structure for buildings is disclosed. This technology discloses "a steel structure wall panel one, a steel structure wall panel two, and an assembly set between the steel structure wall panel one and the steel structure wall panel two. The assembly includes a shell, a shaft set in the shell, a truncated cone coaxially fixed to the shaft, and insert plates symmetrically arranged on both sides of the truncated cone. An adjusting head is fixed to the top of the shaft and a threaded head is fixed to the bottom. A threaded seat that mates with the threaded head is fixed to the inner wall of the bottom of the shell. A guide sleeve is fixed to the inner wall of the shell. The insert plates are slidably placed in the guide sleeve and penetrate the side wall of the shell. This technology has the technical effect that by rotating the adjusting head, the insert plates can be driven to extend or retract into the shell, thereby enabling the two steel structure wall panels to be quickly assembled and fixed together or quickly disassembled."

[0004] However, in the aforementioned comparative documents, although rotating the adjusting head can cause the insert plate to extend or retract into the housing, thereby enabling the two steel structure wall panels to be quickly assembled and fixed together, the return spring may become fatigued, weakened, or even broken due to the long-term use of the building steel structure and its continuous extension and contraction. Once the return spring fails, the insert plate may not be able to retract smoothly into the housing during disassembly, increasing the difficulty of disassembly and reducing the recyclability of the prefabricated building. At the same time, although the adjusting head has a hexagonal adjusting hole for easy wrench operation, if the construction site space is narrow, the wrench may not be able to be used properly, making it difficult to rotate the adjusting head and affecting the efficiency of installation and disassembly. Moreover, if the adjusting hole is rusted or foreign objects enter, it will also affect the fit between the wrench and the adjusting head.

[0005] To address the aforementioned issues, this application proposes a prefabricated steel structure for buildings. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a prefabricated steel structure for buildings.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A prefabricated steel structure for buildings includes a steel structure wall panel and an assembly shell. A connecting component is provided on the assembly shell. The connecting component includes a round rod, a connecting block is rotatably connected to the outer wall of the round rod, a linkage rod is hinged to the side wall of the connecting block, a fixing block is hinged to the bottom end of the linkage rod, a limit hole is opened on the assembly shell, the fixing block is slidably connected to the limit hole opened on the assembly shell, a fixing groove is opened on the side of the steel structure wall panel near the assembly shell, a threaded pipe is fixedly connected to the inner bottom wall of the assembly shell, a threaded groove is opened at the bottom end of the round rod, and a rotating component is provided at the top of the round rod.

[0008] The rotating assembly includes a rotating tube fixedly connected to the top of the round rod, a tension block slidably connected inside the rotating tube, a handle fixedly connected to the top of the tension block, and a positioning assembly provided on the rotating tube. By setting the rotating assembly, convenient rotation of the round rod can be achieved.

[0009] The positioning component includes a housing fixedly connected to the outer wall of the rotating tube, a spring fixedly connected to the inner wall of the housing, and a positioning block fixedly connected to one end of the spring. By setting the positioning component, the positioning of the stretching block can be achieved.

[0010] A second magnetic ring is fixedly connected to the top of the threaded tube, and a first magnetic ring is fixedly connected to the outer wall of the bottom end of the round rod. The round rod is fixed by setting the first magnetic ring and the second magnetic ring.

[0011] The assembly shell is rotatably connected to a ball through an open limiting hole. The outer wall of the ball fits against the side wall of the fixing block. By setting the ball, the fixing block can be moved conveniently.

[0012] The top of the assembly shell is provided with an insertion hole, and an insertion rod is movably connected to the assembly shell through the insertion hole. By setting the insertion hole and the insertion rod, the top of the assembly shell can be sealed.

[0013] A sealing gasket is fixedly connected to the bottom of the insertion rod. The bottom of the sealing gasket is in contact with the top of the assembly shell and the bottom of the sealing gasket is in contact with the top of the steel structure wall panel. By setting the sealing gasket, the interior of the assembly shell is further sealed.

[0014] The beneficial effects of this utility model are:

[0015] When assembly is required, steel structure wall panels are first inserted into the left and right sides of the assembly shell. Then, by rotating the round rod, the round rod moves downward under the action of the threaded tube and threaded groove. At this time, the downward movement of the round rod will drive the connecting block to move downward. The downward movement of the connecting block will push the fixing block through the linkage rod, so that one end of the fixing block is inserted into the fixing groove opened in the steel structure wall panel. At this time, the fixing block is located on the steel structure wall panel and the assembly shell respectively, thus realizing the assembly of the steel structure wall panel and the assembly shell together.

[0016] By setting up a rotating component, the round rod can be easily rotated. When the round rod needs to be rotated, the operator can pull the tension block with the handle to make the tension block a height that is relatively easy to rotate. At this time, the operator can rotate the tension block with the handle, thereby driving the rotation of the rotating tube and the round rod through the rotation of the tension block, thus realizing the rapid assembly of the steel structure wall panel and the assembly shell.

[0030] Reference Figure 1-3A prefabricated steel structure includes a steel structure wall panel 1 and an assembly shell 2. The assembly shell 2 is used to assemble two steel structure wall panels 1 together. A connecting component 3 is provided on the assembly shell 2. The connecting component 3 is used to fix the assembled assembly shell 2 and the steel structure wall panel 1. The connecting component 3 includes a round rod 301 located inside the assembly shell 2. A connecting block 302 is rotatably connected to the outer wall of the round rod 301. Multiple connecting blocks 302 are provided on the round rod 301. A linkage rod 303 is hinged to the side wall of the connecting block 302 on the round rod 301. Linkage rods 303 are respectively provided on the left and right sides of the connecting block 302. A fixing block 304 is hinged to the bottom end of the linkage rod 303. The linkage rod 303 is used to move the connecting block 302 to push the fixing block 304. A limiting hole 305 is opened on the assembly shell 2. The limiting hole 305 is used to limit the fixing block 304. The fixing block 304 is slidably connected to the limiting hole 305 opened on the assembly shell 2. A fixing groove 306 is opened on the side of the steel structure wall panel 1 near the assembly shell 2. The fixing groove 306, the limiting hole 305 and the fixing block 304 work together to assemble the steel structure wall panel 1 and the assembly shell 2 together. A threaded tube 307 is fixedly connected to the inner bottom wall of the assembly shell 2. A threaded groove 308 is opened at the bottom end of the round rod 301. The working of the threaded tube 307 and the threaded groove 308 can realize the rotation and downward movement of the round rod 301 and fix the round rod 301 and its related components, thereby fixing the steel structure wall panel 1 and the assembly shell 2. A rotating component 4 is provided on the top of the round rod 301.

[0031] Reference Figure 3 and Figure 4 The rotating assembly 4 includes a rotating tube 401 fixedly connected to the top end of the round rod 301. The rotating tube 401 is used to realize the rotation of the round rod 301. A tension block 402 is slidably connected inside the rotating tube 401. A handle 403 is fixedly connected to the top of the tension block 402. The handle 403 is used to facilitate the operator to pull the tension block 402, thereby facilitating the rotation of the rotating tube 401 and the round rod 301. A positioning assembly 5 is provided on the rotating tube 401.

[0032] Reference Figure 4 The positioning component 5 includes a housing 501 fixedly connected to the outer wall of the rotating tube 401, and a spring 502 fixedly connected to the inner wall of the housing 501. The housing 501 is used to fix the spring 502. A positioning block 503 is fixedly connected to one end of the spring 502. The spring 502 is used to realize the extension and retraction of the positioning block 503. The positioning block 503 prevents the stretching block 402 from leaving the range of the rotating tube 401 after rotation, thereby avoiding affecting the rotation of the stretching block 402 and driving the rotation of the rotating tube 401.

[0033] Reference Figure 3A second magnetic ring 7 is fixedly connected to the top of the threaded tube 307, and a first magnetic ring 6 is fixedly connected to the outer wall of the bottom end of the round rod 301. The cooperation of the first magnetic ring 6 and the second magnetic ring 7 can fix the round rod 301. After the round rod 301 is threadedly connected to the threaded tube 307, the round rod 301 can be further fixed by the cooperation of the first magnetic ring 6 and the second magnetic ring 7, so as to prevent the round rod 301 from coming off after being vibrated, thereby avoiding affecting the assembly connection of the assembly shell 2 and the steel structure wall panel 1.

[0034] Reference Figure 3 The assembly shell 2 is rotatably connected to a ball 8 through an open limiting hole 305. The outer wall of the ball 8 fits against the side wall of the fixing block 304. The ball 8 is used to facilitate the movement of the fixing block 304 and avoid the fixing block 304 from being stuck due to excessive friction during movement, thereby avoiding affecting the assembly effect of the fixing block 304 on the steel structure wall panel 1 and the assembly shell 2.

[0035] Reference Figure 2 The top of the assembly shell 2 is provided with an insertion hole 9. The assembly shell 2 is movably connected to the insertion rod 10 through the insertion hole 9. The cooperation of the insertion hole 9 and the insertion rod 10 can seal the top of the assembly shell 2, preventing the components inside the assembly shell 2 from being affected by external factors and becoming rusted or damaged.

[0036] Reference Figure 2 A sealing gasket 11 is fixedly connected to the bottom of the insertion rod 10. The bottom of the sealing gasket 11 is in contact with the top of the assembly shell 2 and the bottom of the sealing gasket 11 is in contact with the top of the steel structure wall panel 1. The sealing gasket 11 is used to further seal the inside of the assembly shell 2, thereby extending the service life of the internal components of the assembly shell 2.

[0037] Working principle:

[0038] When assembling this prefabricated steel structure, steel structure wall panels 1 are first inserted into the left and right sides of the assembly shell 2. Then, the worker can pull the tension block 402 through the handle 403 to make the tension block 402 a relatively convenient height for rotation. At this time, the worker can rotate the tension block 402 through the handle 403. This rotation of the tension block 402 drives the rotation tube 401 and the round rod 301 to rotate. When the round rod 301 rotates, it is moved downward by the threaded tube 307 and the threaded groove 308. At this time, the downward movement of the round rod 301 will drive the connecting block 302 to move downward. The downward movement of the connecting block 302 will push the fixing block 304 through the linkage rod 303, so that one end of the fixing block 304 is inserted into the fixing groove 306 opened in the steel structure wall panel 1. At this time, the fixing block 304 is located on the steel structure wall panel 1 and the assembly shell 2 respectively, thus realizing the assembly of the steel structure wall panel 1 and the assembly shell 2 together.
