Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a modular building connector. Background Technology

[0002] Modular building connectors are core components of prefabricated buildings, used to achieve rapid and reliable connections between prefabricated modules (such as wall panels, floor slabs, and box units). Their design must meet requirements for high strength, lightweight, seismic resistance, and ease of installation, directly impacting the overall stability, construction efficiency, and service life of the building. This technology is key to promoting the development of prefabricated buildings and intelligent construction, and is expected to further revolutionize the construction industry in the future by combining with technologies such as AI design and robotic installation.

[0003] Traditional modular buildings often use rivets, bolts, welding, and other fixing methods to directly fix prefabricated walls when designing connectors. These fixing methods only consider the stability of the connection and ignore the function of quick installation and disassembly of the connectors. The single fixing method cannot be reused, which increases costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a modular building connector.

[0005] The technical solution adopted to solve the above technical problem is as follows: it includes a first connector, a second connector is provided on the left side of the first connector, the first connector and the second connector are provided with a number of reserved openings on the side close to each other, the reserved openings are provided with a snap-fit ​​device inside, the middle part of the first connector and the second connector are provided with a reserved sliding groove, a central column is slidably connected inside the reserved sliding groove, and the upper and lower sides of the central column are provided with a closing plate.

[0006] Furthermore, the enclosure plate is provided with several fixing bolts around its perimeter, the fixing bolts penetrating the enclosure plate, and the first connector and the second connector are provided with several bolt holes on their upper and lower sides, the bolt holes and fixing bolts being arranged correspondingly.

[0007] Furthermore, the first connector and the second connector are provided with a plurality of connecting bolts on their front and rear sides, and the connecting bolts penetrate the first connector and the second connector.

[0008] The above solution involves setting connecting bolts on both sides of the first and second connectors, setting a central column in the middle, setting a snap-fit ​​device on the side close to each other, and setting a closing plate on the top. The snap-fit ​​device is used to initially fix the first and second connectors, and then the central column and closing plate are used to fix them a second time. This arrangement allows the prefabricated partition wall to be quickly connected and fixed. The double fixing keeps it stable, while the connectors can be quickly disassembled and reused, saving costs.

[0009] Furthermore, the snap-fit ​​device includes a pull bolt located on the front and rear sides of the first connector. An auxiliary component is threaded onto the external side of the pull bolt, and the auxiliary component is fixedly connected to the first connector. A plug-in block is rotatably connected to one end of the pull bolt near the central post. Several convex blocks are fixedly connected to the side of the plug-in block away from the second connector. The convex blocks are slidably connected to the first connector. The auxiliary component, the plug-in block, and the convex blocks are all located inside the first connector.

[0010] Furthermore, the snap-fit ​​device includes a snap-fit ​​block and a plug-in block, the snap-fit ​​block and the plug-in block are respectively arranged, a connecting rod is fixedly connected to the side of the snap-fit ​​block near the central column, the connecting rod and the second connecting piece are plugged in, and a spring is provided on the outside of the connecting rod, the spring is fixedly connected to the snap-fit ​​block and the second connecting piece respectively.

[0011] The above scheme involves the plug-in block contacting the snap-fit ​​block inside the reserved opening, causing the connecting rod on the snap-fit ​​block to move and the spring to retract, thus securing the plug-in block and the snap-fit ​​block together. Disassembly is achieved by rotating the pull bolt, whose external thread connects to an auxiliary component. This auxiliary component is fixedly connected to the first connecting component, and the pull bolt is rotatably connected to the plug-in block. The rotation of the pull bolt causes the plug-in block to move, releasing the plug-in block from the snap-fit ​​block and separating the first and second connecting components, thus completing the disassembly process.

[0012] The beneficial effects of this utility model are as follows: This utility model provides connecting bolts on both sides of the first and second connecting parts, a central column in the middle, a snap-fit ​​device on the side close to each other, and a closing plate on the top. The snap-fit ​​device initially fixes the first and second connecting parts, and then the central column and closing plate fix them a second time. This design allows the prefabricated partition wall to be quickly connected and fixed. The double fixation keeps it stable while the connecting parts can be quickly disassembled and reused, saving costs. Attached Figure Description

The connecting bolts 6 pass through the first connector 1 and the second connector 2. A plurality of reserved openings 7 are provided on the side of the first connector 1 and the second connector 2 that are close to each other. The reserved openings 7 are provided with snap-fit ​​devices 8 inside.

[0017] The snap-fit ​​device 8 includes a pull bolt 801, which is located on the front and rear sides of the first connecting member 1. An auxiliary member 802 is threaded onto the outside of the pull bolt 801. The auxiliary member 802 is fixedly connected to the first connecting member 1 and is used to cooperate with the rotation of the pull bolt 801. A plug block 803 is rotatably connected to one end of the pull bolt 801 near the central post 3. Several convex blocks 804 are fixedly connected to the side of the plug block 803 away from the second connecting member 2. The convex blocks 804 are slidably connected to the first connecting member 1 and are used to assist the plug block 803 in the rotation of the pull bolt 801. The device moves downwards. The auxiliary component 802, the plug-in block 803, and the convex block 804 are all located inside the first connecting component 1. The snap-fit ​​device 8 includes a snap-fit ​​block 805, which is correspondingly arranged with the plug-in block 803. A connecting rod 806 is fixedly connected to the side of the snap-fit ​​block 805 near the central column 3. The connecting rod 806 is plugged into the second connecting component 2. A spring 807 is provided on the outside of the connecting rod 806. The spring 807 is used to use its own elasticity to cooperate with the snap-fit ​​block 805 to fix the plug-in block 803. The spring 807 is fixedly connected to the snap-fit ​​block 805 and the second connecting component 2 respectively.

[0018] Both the first connector 1 and the second connector 2 have a reserved sliding groove 4 in the middle. A central column 3 is slidably connected inside the reserved sliding groove 4. The central column 3 is used to insert into the reserved sliding groove 4 so that the first connector 1 and the second connector 2 are snapped together and fixed.

Both the upper and lower sides of the first connector 1 and the second connector 2 are provided with several bolt holes 10. The bolt holes 10 and the fixing bolts 9 are set accordingly.

[0019] The working principle of this embodiment is as follows: During installation, the first connector 1 and the second connector 2 are connected to the two prefabricated wall panels respectively by connecting bolts 6. The first connector 1 and the second connector 2 are brought into contact, so that the plug-in block 803 provided on the first connector 1 is inserted into the reserved opening 7 provided on the second connector 2. The plug-in block 803 abuts against the snap-fit ​​block 805 provided inside the reserved opening 7, so that the connecting rod 806 provided on the snap-fit ​​block 805 moves and the spring 807 retracts, so that the plug-in block 803 and the snap-fit ​​block 805 are snapped and fixed, and the initial fixing of the first connector 1 and the second connector 2 is completed.

[0020] After initial fixation, the central column 3 is inserted into the reserved sliding groove 4 set in the middle of the first connector 1 and the second connector 2.

The sealing plate 5 is set on the upper and lower sides of the central column 3, and the sealing plate 5 is connected and fixed to the first connector 1 and the second connector 2 by the fixing bolt 9, thus sealing the central column 3 and preventing it from falling off.

[0021] During disassembly, the sealing plate 5 is removed, the central column 3 is taken out, and the pull bolt 801 is rotated. The pull bolt 801 is externally threaded with an auxiliary component 802. The auxiliary component 802 is fixedly connected to the first connecting component 1. The pull bolt 801 is rotatably connected to the plug block 803. The rotation of the pull bolt 801 drives the movement of the plug block 803, thereby releasing the plug block 803 from the snap block 805, separating the first connecting component 1 and the second connecting component 2, and completing the disassembly work.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
