Description

Technical Field

[0001] This application relates to the technical field of connection structures for multi - storey steel - structure buildings, and particularly relates to a connection structure for prefabricated multi - storey steel - structure buildings. Background Technique

[0002] A prefabricated steel - structure building is a building constructed with steel as the basic material. Compared with traditional buildings, prefabricated steel - structure buildings have the advantages of light self - weight, high strength, good seismic performance, low cost, little restriction by climatic conditions, short construction period, and convenient construction. At the same time, prefabricated steel - structure buildings are also representatives of green buildings and are the development trend of buildings in our country. Especially the modular characteristics are more in line with the requirements of industrial development in our country and have good application prospects and market potential.

[0003] Most of the existing assembly structures rely on bolt structures and are relatively cumbersome during the installation and disassembly processes of assembly. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, this application provides a connection structure for prefabricated multi - storey steel - structure buildings, which overcomes the deficiencies of the existing technology and aims to solve the problem that most of the existing assembly structures rely on bolt structures and are relatively cumbersome during the installation and disassembly processes of assembly.

[0005] To achieve the above - mentioned purpose, this application provides the following technical solution: A connection structure for prefabricated multi - storey steel - structure buildings includes a foundation. Above the foundation, a plurality of groups of steel - structure columns are fixedly connected. The other ends of the plurality of groups of steel - structure columns are all sleeved with connection blocks. An assembly groove and an abutment groove are opened inside the connection blocks. Two rotating columns are installed inside the foundation. Clamping columns are installed on the outer sides of the two rotating columns. One ends of the two clamping columns are provided with engaging teeth. A steel - structure frame is sleeved inside the assembly groove. Engaging grooves are opened on both sides of the steel - structure frame. The two engaging grooves are correspondingly arranged with the two engaging teeth. A spring is installed inside the abutment groove. A limiting block is installed on the side of the abutment groove close to the assembly groove. One end of the spring is fixedly connected with an abutting plate.

[0006] By adopting the above technical solution, by setting the connecting block, during installation, the steel structure frame can be inserted into the assembly groove. As the steel structure frame enters the interior of the assembly groove, it will trigger the clamping column to rotate on the rotating column, causing the clamping teeth to approach the clamping groove. After the construction personnel make the steel structure frame abut against the abutting plate, when the abutting plate squeezes the spring, it will cause the spring to expand and contract. In this way, the clamping teeth will fall into the interior of the clamping groove. After the construction personnel release the steel structure frame, the spring exerts a supporting force on the steel structure frame through the abutting plate, causing the clamping teeth to tightly clamp the clamping groove under the action of force. When it is necessary to disassemble and replace the steel structure frame, the construction personnel can squeeze the spring with the steel structure frame, so that the clamping teeth pop out of the clamping groove, and thus the steel structure frame can be disassembled from the interior of the assembly groove. Such a setting makes the device more convenient for assembly and disassembly, and the device has fewer components and is not easily damaged, effectively improving the assembly efficiency.

[0007] As a preferred technical solution of the present application, two sets of moving grooves are provided on one side of the connecting block. The two sets of moving grooves are located on both sides of the assembly groove. A moving block is installed inside the moving groove. A groove is provided above the clamping teeth, and the groove is correspondingly arranged with the moving block.

[0008] By adopting the above technical solution, by setting the moving groove, when the device is not assembled, the moving block inside can be pushed into the groove through the moving groove to limit the clamping column, preventing the clamping column from moving and being damaged during placement and transportation, and improving the practicality of the device.

[0009] As a preferred technical solution of the present application, two sets of bolts I are installed on the outer side of the connecting block. The two sets of bolts I penetrate through the connecting block, the abutting groove and the abutting plate and are rotatably connected to one end of the steel structure frame.

[0010] By adopting the above technical solution, by setting the bolts I, after the device is assembled, the device can be reinforced by setting two sets of bolts I, preventing the steel structure frame from displacing under the action of external force after the device is assembled and causing the phenomenon of unstable assembly, and improving the safety of the device.

[0011] As a preferred technical solution of the present application, a rubber pad is provided on the inner side of the clamping teeth.

[0012] By adopting the above technical solution, by setting the rubber pad, the connection between the clamping teeth and the clamping groove can be made closer, improving the stability of the device assembly.

[0013] As a preferred technical solution of the present application, a bolt II is installed inside the clamping column.

[0014] By adopting the above technical solution, the connection between the clamping column and the steel structure frame can be strengthened by setting the second bolt, preventing accidental detachment and affecting the normal use of the device.

[0015] As a preferred technical solution of the present application, a plurality of groups of third bolts are installed on the outer side of the socket joint of the connecting block and the steel structure column, and the plurality of groups of third bolts penetrate through the connecting block and are rotatably connected to the steel structure column.

[0016] By adopting the above technical solution, the socket joint between the steel structure column and the connecting block can be made more stable by setting the third bolt, improving the overall stability of the device.

[0017] Advantages of the present application:

[0018] 1. By setting the connecting block, during installation, the steel structure frame can be inserted into the assembly groove. As the steel structure frame enters the interior of the assembly groove, it will trigger the clamping column to rotate on the rotating column, causing the clamping teeth to approach the clamping groove. After the construction personnel make the steel structure frame abut against the abutting plate, when the abutting plate presses the spring, it will cause the spring to expand and contract. This will cause the clamping teeth to fall into the interior of the clamping groove. After the construction personnel release the steel structure frame, the spring applies a supporting force to the steel structure frame through the abutting plate, causing the clamping teeth to tightly clamp the clamping groove under the action of force. When it is necessary to disassemble and replace the steel structure frame, the construction personnel can squeeze the spring with the steel structure frame, which will cause the clamping teeth to pop out of the clamping groove, and thus the steel structure frame can be disassembled from the interior of the assembly groove. Such a setting makes the device more convenient for assembly and disassembly, and has fewer device components and is not easily damaged, effectively improving the assembly efficiency.

[0019] 2. By setting the moving groove, when the device is not assembled, the internal moving block can be pushed into the groove through the moving groove to limit the clamping column, preventing the clamping column from moving and being damaged during placement and transportation, improving the practicality of the device.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] Refer to Figures 1-3 , a connection structure of a prefabricated multi-storey steel structure building, including a foundation 1, a plurality of groups of steel structure columns 2 are fixedly connected above the foundation 1, the other ends of the plurality of groups of steel structure columns 2 are all sleeved with connecting blocks 3, an assembly groove 301 and an abutting groove 303 are opened inside the connecting block 3, two groups of rotating columns 302 are installed inside the foundation 1, two groups of clamping columns 4 are installed outside the two groups of rotating columns 302, clamping teeth 401 are arranged at one ends of the two groups of clamping columns 4, a steel structure frame 5 is sleeved inside the assembly groove 301, clamping grooves 501 are opened on both sides of the steel structure frame 5, and the two groups of clamping grooves 501 are correspondingly arranged with the two groups of clamping teeth 401. A spring 304 is installed inside the abutting groove 303, a limiting block 306 is installed on one side of the abutting groove 303 close to the assembly groove 301, and one end of the spring 304 is fixedly connected with an abutting plate 305. Two groups of bolts one 307 are installed on the outer side of the connecting block 3, and the two groups of bolts one 307 penetrate through the connecting block 3, the abutting groove 303 and the abutting plate 305 and are rotatably connected to one end of the steel structure frame 5.

[0027] By setting the connecting block 3, during installation, the steel structure frame 5 can be inserted into the assembly groove 301. As the steel structure frame 5 enters the interior of the assembly groove 301, it will trigger the clamping column 4 to rotate on the rotating column 302, causing the clamping teeth 401 to approach the clamping groove 501. After the construction worker makes the steel structure frame 5 abut against the abutting plate 305, when the abutting plate 305 squeezes the spring 304, it will cause the spring 304 to expand and contract. This will make the clamping teeth 401 fall into the interior of the clamping groove 501. After the construction worker releases the steel structure frame 5, the spring 304 exerts a supporting force on the steel structure frame 5 through the abutting plate 305, causing the clamping teeth 401 to be clamped tightly in the clamping groove 501 under the action of force. When it is necessary to disassemble and replace the steel structure frame 5, the construction worker can squeeze the spring 304 with the steel structure frame 5, which will cause the clamping teeth 401 to pop out of the clamping groove 501, so that the steel structure frame 5 can be disassembled from the interior of the assembly groove 301. Such a setting makes the device more convenient for assembly and disassembly, and the device has fewer components and is not easily damaged, effectively improving the assembly efficiency; by setting the first bolt 307, after the device is assembled, the device can be reinforced by setting two groups of the first bolts 307, preventing the assembly from being unstable due to the displacement of the steel structure frame 5 under the action of external force after the device is assembled, and improving the safety of the device.

[0028] Refer to Figure 1 , two moving grooves 308 are opened on one side of the connecting block 3. The two moving grooves 308 are located on both sides of the assembly groove 301. A moving block 309 is installed inside the moving groove 308. A groove 402 is opened above the clamping teeth 401, and the groove 402 is arranged corresponding to the moving block 309; a rubber pad is arranged inside the clamping teeth 401. A plurality of groups of third bolts 201 are installed on the outer side of the socket joint between the connecting block 3 and the steel structure column 2. The plurality of groups of third bolts 201 penetrate through the connecting block 3 and are rotatably connected to the steel structure column 2; by setting the moving groove 308, when the device is not assembled, the moving block 309 inside can be pushed into the interior of the groove 402 through the moving groove 308 to limit the clamping column 4, preventing the clamping column 4 from moving and being damaged during placement and transportation, and improving the practicability of the device; by setting the rubber pad, the connection between the clamping teeth 401 and the clamping groove 501 can be made closer, improving the stability of the device assembly; by setting the third bolts 201, the socket joint between the steel structure column 2 and the connecting block 3 can be made more stable, improving the overall stability of the device.

[0029] Refer to Figure 1 , a second bolt 403 is installed inside the clamping column 4; by setting the second bolt 403, the connection between the clamping column 4 and the steel structure frame 5 can be reinforced, preventing it from falling off due to accidents and affecting the normal use of the device.

[0030] Working principle: By setting the connecting block 3, during installation, the steel structure frame 5 can be inserted into the assembly groove 301. As the steel structure frame 5 enters the interior of the assembly groove 301, it will trigger the clamping column 4 to rotate on the rotating column 302, causing the clamping teeth 401 to approach the clamping groove 501. After the construction personnel make the steel structure frame 5 abut against the abutting plate 305, when the abutting plate 305 squeezes the spring 304, it will cause the spring 304 to expand and contract, so that the clamping teeth 401 will fall into the interior of the clamping groove 501. After the construction personnel release the steel structure frame 5, the spring 304 exerts a supporting force on the steel structure frame 5 through the abutting plate 305, causing the clamping teeth 401 to be clamped tightly in the clamping groove 501 under the action of force. When it is necessary to disassemble and replace the steel structure frame 5, the construction personnel can squeeze the spring 304 with the steel structure frame 5, so that the clamping teeth 401 will pop out of the clamping groove 501, and then the steel structure frame 5 can be disassembled from the interior of the assembly groove 301. Such a setting makes the device more convenient for assembly and disassembly, and the device has fewer components and is not easily damaged, effectively improving the assembly efficiency. By setting the moving groove 308, when the device is not assembled, the internal moving block 309 can be pushed into the groove 402 through the moving groove 308 to limit the clamping column 4, preventing the clamping column 4 from moving and being damaged during placement and transportation, enhancing the practicality of the device;

[0031] Among them, by setting the first bolt 307, after the device is assembled, two groups of the first bolts 307 can be set to reinforce the device, preventing the phenomenon of unstable assembly caused by the displacement of the steel structure frame 5 under the action of external force after the device is assembled, enhancing the safety of the device. By setting the rubber pad, the connection between the clamping teeth 401 and the clamping groove 501 can be made tighter, enhancing the stability of the device assembly;

[0032] At the same time, by setting the second bolt 403, the connection between the clamping column 4 and the steel structure frame 5 can be reinforced, preventing it from falling off due to accidents and affecting the normal use of the device;

[0033] In addition, by setting the third bolt 201, the socket connection between the steel structure column 2 and the connecting block 3 can be made more stable, enhancing the overall stability of the device.

[0034] The above are only the preferred embodiments of the present application and are not used to limit the present application.
