Description

Technical Field

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

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] In prefabricated buildings, wall panels are typically connected using connectors. Prefabricated wall panels use high-strength magnesium oxide flat panels as the faceplate and light steel keel as the frame. The wall core is cast from lightweight, non-toxic, and flame-retardant materials, highlighting the characteristics of lightweight, energy saving, and environmental protection. During the installation of wall panels, installation errors can easily occur, resulting in excessive gaps between the wall panels. However, existing wall panel connectors have poor adjustability, making it difficult to adjust the gaps between the wall panels after installation. Utility Model Content

[0004] The purpose of this utility model is to provide a connector for prefabricated buildings to solve the problem mentioned in the background art that the existing wall panel connectors have poor adjustability and it is difficult to adjust the gap between the wall panels after installation.

[0006] Preferably, the mounting groove is formed on the surface of the first wall panel and the second wall panel, the mounting plate is plate-shaped, and the mounting plate is movably connected to the mounting groove by mounting bolts.

[0007] Preferably, the cross-section of the fixing sleeve is U-shaped, and two sets of mounting plates are fixedly connected to the surface of the fixing sleeve.

[0008] Preferably, the connecting plate is plate-shaped and is movably connected to the mounting groove via a mounting plate and a fixing sleeve, and the limiting plate is circular.

[0009] Preferably, the lead screw is movably connected to a limiting plate and a connecting plate, the movable block is block-shaped, and the movable block is slidably connected to the lead screw and the connecting plate.

[0010] Preferably, the movable sleeve has a cross-section in the shape of a "U". The movable sleeve is slidably connected by a moving block and a connecting plate, and two sets of mounting plates are fixedly connected to the surface of the movable sleeve.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A connector for a prefabricated building includes a first wall panel 1, with a second wall panel 2 disposed on the surface of the first wall panel 1. Both the first wall panel 1 and the second wall panel 2 are part of a unit wall panel. An installation groove 3 is formed on the surface of the first wall panel 1 for installing the connector, ensuring that the connector is not excessively exposed. An installation bolt 4 is threaded onto the surface of the installation groove 3, and an installation plate 5 is movably connected to the surface of the installation bolt 4. The installation bolt 4 and the installation plate 5 are used to install a fixed sleeve 6, a connecting plate 7, and a movable sleeve 12 onto the first wall panel 1 and the second wall panel 2 respectively, thereby connecting the first wall panel 1 and the second wall panel 2. Wall panels 2 are connected together. A fixing sleeve 6 is fixedly connected to the surface of mounting plate 5. The fixing sleeve 6 connects mounting plate 5 and connecting plate 7. A connecting plate 7 is fixedly connected to the surface of fixing sleeve 6, connecting sleeve 6 and movable sleeve 12 together, thus connecting the first wall panel 1 and the second wall panel 2 together. A limiting plate 8 is movably connected inside connecting plate 7, limiting the movement of screw 9, allowing screw 9 to rotate only in place. Screw 9 is fixedly connected to the surface of limiting plate 8, driving moving block 11 to move movable sleeve 12, thereby enabling... The second wall panel 2 can be moved, thereby adjusting the gap between the first wall panel 1 and the second wall panel 2. A rotating head 10 is fixedly connected to the end of the lead screw 9 away from the limiting plate 8. The rotating head 10 facilitates the rotation of the lead screw 9. A moving block 11 is movably connected to the surface of the lead screw 9. The moving block 11 drives the movable sleeve 12 to move, thereby moving the second wall panel 2 and adjusting the gap between the first wall panel 1 and the second wall panel 2. The movable sleeve 12 is fixedly connected to the surface of the moving block 11, connecting the moving block 11 and the second wall panel 2. The surface of the connecting plate 7 is fixed... A first magnetic block 13 is connected, and a second magnetic block 14 is magnetically connected to the surface of the first magnetic block 13. The first magnetic block 13 and the second magnetic block 14 are used to realize the installation and removal of the cover plate 15. The cover plate 15 is fixedly connected to the surface of the second magnetic block 14. The cover plate 15 is used to cover the connector, thereby preventing the connector from being exposed on the outside of the wall panel, increasing the aesthetics of the wall panel connection, and preventing the connector from being corroded by rainwater, thus increasing the service life of the connector. A fastening groove 16 is opened on the surface of the first wall panel 1. The fastening groove 16 is used to make it easy for people to fasten the cover plate 15, thereby facilitating the removal of the cover plate 15.

[0024] Furthermore, both the first wall panel 1 and the second wall panel 2 are part of the unit wall panel. The mounting groove 3 is formed on the surface of the first wall panel 1 and the second wall panel 2. The mounting groove 3 is used to install the connectors so that the connectors are not exposed too much. The mounting plate 5 is plate-shaped and is movably connected to the mounting groove 3 by the mounting bolt 4. The mounting bolt 4 and the mounting plate 5 are used to install the fixing sleeve 6, the connecting plate 7 and the movable sleeve 12 on the first wall panel 1 and the second wall panel 2 respectively, thereby connecting the first wall panel 1 and the second wall panel 2 together.

[0025] Further, the cross-section of the fixing sleeve 6 is in a "U" shape. Two groups of mounting plates 5 are fixedly connected to the surface of the fixing sleeve 6. The fixing sleeve 6 is used to connect the mounting plate 5 and the connecting plate 7.

[0026] Further, the connecting plate 7 is in a plate shape. The connecting plate 7 is movably connected to the mounting groove 3 through the mounting plate 5 and the fixing sleeve 6. The connecting plate 7 is used to connect the fixing sleeve 6 and the movable sleeve 12 together, thereby connecting the first wall panel 1 and the second wall panel 2 together. The limiting plate 8 is in a round plate shape. The limiting plate 8 is used to limit the movement of the screw rod 9, so that the screw rod 9 can only rotate in place.

[0027] Further, the screw rod 9 is movably connected through the limiting plate 8 and the connecting plate 7. The screw rod 9 is used to drive the moving block 11 to move the movable sleeve 12, thereby moving the second wall panel 2, and further adjusting the gap size between the first wall panel 1 and the second wall panel 2. The rotating head 10 is used to facilitate the rotation of the screw rod 9. The moving block 11 is in a block shape. The moving block 11 is slidably connected to the connecting plate 7 through the screw rod 9. The moving block 11 is used to move the movable sleeve 12, thereby moving the second wall panel 2, and further adjusting the gap size between the first wall panel 1 and the second wall panel 2.

[0028] Further, the cross-section of the movable sleeve 12 is in a "U" shape. The movable sleeve 12 is slidably connected to the connecting plate 7 through the moving block 11. Two groups of mounting plates 5 are fixedly connected to the surface of the movable sleeve 12. The movable sleeve 12 is used to connect the moving block 11 and the second wall panel 2.

[0029] Further, two groups of first magnetic blocks 13 are symmetrically distributed on the surface of the connecting plate 7. Two groups of second magnetic blocks 14 are symmetrically distributed on the surface of the shielding plate 15. The first magnetic blocks 13 and the second magnetic blocks 14 are used to install and disassemble the shielding plate 15. The shielding plate 15 is in a plate shape. The shielding plate 15 is movably connected to the connecting plate 7 through the second magnetic blocks 14 and the first magnetic blocks 13. The shielding plate 15 is used to block the connecting parts, thereby preventing the connecting parts from being exposed outside the wall panel, increasing the aesthetic appearance of the wall panel connection, and at the same time preventing the connecting parts from being eroded by rainwater, increasing the service life of the connecting parts. The buckling groove 16 is used to facilitate people to buckle down the shielding plate 15, thereby facilitating the disassembly of the shielding plate 15.

[0030] Working principle: Rotating the rotating head 10 to drive the screw rod 9 to rotate can control the moving block 11 to move the movable sleeve 12, thereby moving the second wall panel 2, and further adjusting the gap size between the first wall panel 1 and the second wall panel 2.

[0031] After the connecting parts are installed, the shielding plate 15 can be installed on the connecting plate 7 to block the connecting parts, thereby preventing the connecting parts from being exposed outside the wall panel, increasing the aesthetic appearance of the wall panel connection, and at the same time preventing the connecting parts from being eroded by rainwater, increasing the service life of the connecting parts.
