Description

Technical Field

[0001] This utility model relates to the field of steel frame lightweight panel technology, and more specifically, to a combination connection device for prefabricated assembled steel frame lightweight panels. Background Technology

[0002] In the field of prefabricated buildings, the connection technology of prefabricated steel frame lightweight panels is a key factor affecting building quality and construction efficiency.

[0003] In most existing connection methods, when a building needs to be renovated or demolished, the steel frame lightweight panels are difficult to completely disassemble from the connection structure. Even if they are disassembled, the panels and connecting parts will be damaged, making them unusable and resulting in resource waste and increased costs. In urban old building renovation projects, due to the non-removable nature of the connection devices, the steel frame lightweight panels cannot be reused, and new panels need to be purchased, increasing the renovation cost. Utility Model Content

[0004] In order to overcome the problems and defects in the prior art, this utility model provides a prefabricated assembled steel frame lightweight panel combination connection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined connection device for a prefabricated assembled steel frame lightweight panel, comprising a steel frame lightweight panel, a connecting column provided on one side of the steel frame lightweight panel, and a combined connection mechanism provided between the steel frame lightweight panel and the connecting column;

[0006] The combined connecting mechanism includes a fixing block, which is fixedly connected to one side of the steel frame lightweight panel. The top and bottom surfaces of the fixing block are provided with slots. Multiple connecting slots are evenly provided on one side surface of the fixing block. The two sides of the connecting column are provided with fixing slots. A square slot is provided inside the connecting column near the top of the fixing slot. A threaded rod is rotatably connected inside the square slot. A threaded sleeve is threadedly connected to the outside of the threaded rod. Connecting square blocks are fixedly connected to both sides of the threaded sleeve. A movable locking column is fixedly connected to the bottom of the connecting square block.

[0007] Preferably, the threaded rod is rotatably connected to the connecting column, the connecting square block is slidably connected to the square groove, and the connecting square block and the square groove have the same width.

[0008] Preferably, a groove is formed on the top surface of the connecting column, and a rotating ring is installed inside the groove.

[0009] Preferably, the card slot and the movable card post are movably engaged, and the fixed card block and the fixed card slot are movably engaged.

[0010] Preferably, a plurality of connecting friction plates are fixedly connected to one side of the inner wall of the fixed slot, and the connecting friction plates are movably engaged with the connecting slot.

[0011] Preferably, the plurality of connecting friction plates are evenly distributed along the inner wall of the fixing slot, the connecting friction plates are made of plastic, and the surfaces of the connecting friction plates that contact the connecting slot are provided with raised particles.

[0012] Preferably, the top of the threaded rod passes through the connecting post and extends into the groove, and the bottom of the rotating ring is fixedly connected to the threaded rod.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The initial positioning of the fixed card block and the fixed card slot, combined with the rigid locking of the moving card column inserted into the card slot, forms a double guarantee of mechanical connection to avoid loosening. The connecting friction plate in the fixed card slot is made of plastic and has raised particles on the surface. After being embedded in the connecting slot, it can provide additional friction force, effectively preventing lateral displacement between the steel frame lightweight panel and the connecting column. The square slot limits the connection square block to prevent the threaded sleeve from rotating with the threaded rod, ensuring the precise displacement and stable connection of the moving card column. This facilitates the rapid assembly and combination of the steel frame lightweight panel and improves the splicing efficiency. The modular design of the steel frame lightweight panel and the connecting column is suitable for prefabricated building scenarios, which facilitates standardized production and installation. It can be quickly disassembled to avoid the steel frame lightweight panel being unable to be disassembled and thus unable to be reused, which would increase costs.

[0015] 2. The initial engagement of the fixed card block and the fixed card slot enables quick positioning. Rotating the rotating ring drives the moving card column through the threaded rod to complete the locking. The operation is simple. Rotating the rotating ring in the opposite direction can unlock the device. The elastic deformation characteristics of the connecting friction plate make it less prone to damage when separated. The device can be reused, reducing costs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] As attached Figure 1-6 The present invention relates to a prefabricated assembled steel frame lightweight panel combination connection device, comprising a steel frame lightweight panel 1, a connecting column 2 provided on one side of the steel frame lightweight panel 1, and a combination connection mechanism provided between the steel frame lightweight panel 1 and the connecting column 2.

[0025] The combined connection mechanism includes a fixed locking block 3, which is fixedly connected to one side of the steel frame lightweight panel 1. The top and bottom surfaces of the fixed locking block 3 are provided with locking grooves 4. Multiple connecting grooves 5 are evenly provided on one side surface of the fixed locking block 3. The two sides of the connecting column 2 are provided with fixed locking grooves 6. The inside of the connecting column 2 is provided with a square groove 7 near the top of the fixed locking groove 6. A threaded rod 8 is rotatably connected inside the square groove 7. A threaded sleeve 9 is threadedly connected to the outside of the threaded rod 8. Connecting square blocks 10 are fixedly connected to both sides of the threaded sleeve 9. A movable locking column 11 is fixedly connected to the bottom of the connecting square block 10.

[0026] As attached Figure 5 , 6 As shown, the threaded rod 8 is rotatably connected to the connecting column 2, and the connecting square block 10 is slidably connected to the square groove 7. The width of the connecting square block 10 and the square groove 7 are the same, which serves as a limit to prevent the connecting square block 10 and the threaded sleeve 9 from rotating with the threaded rod 8.

[0027] As attached Figure 1 , 2 As shown in Figures 3, 5, and 6, a groove 12 is provided on the top surface of the connecting column 2. A rotating ring 13 is installed inside the groove 12 so that the rotating ring 13 is housed in the groove 12, thus avoiding affecting the use of the steel frame lightweight panel 1.

[0028] As attached Figure 1-6As shown, the slot 4 is movably engaged with the movable slot 11, and the fixed slot 3 is movably engaged with the fixed slot 6, which facilitates quick positioning and assembly.

[0029] As attached Figure 1-4 As shown, multiple connecting friction plates 14 are fixedly connected to one side of the inner wall of the fixed slot 6. The connecting friction plates 14 are movably engaged with the connecting slot 5. The multiple connecting friction plates 14 are evenly distributed along the inner wall of the fixed slot 6. The connecting friction plates 14 are made of plastic, and the surfaces of the connecting friction plates 14 that contact the connecting slot 5 are provided with raised particles to improve the splicing friction and thus improve the assembly stability of the steel frame lightweight plate 1.

[0030] As attached Figure 5 , 6 As shown, the top of the threaded rod 8 passes through the connecting post 2 and extends into the groove 12. The bottom of the rotating ring 13 is fixedly connected to the threaded rod 8, so that the rotating ring 13 rotates and drives the threaded rod 8 to rotate.

[0031] The working principle of this utility model is as follows: The steel frame lightweight plate 1 is initially positioned by the fixing block 3 and the fixing groove 6 of the connecting column 2. The connecting groove 5 of the fixing block 3 is aligned with the connecting friction plate 14 in the fixing groove 6 to form an initial frictional connection. Rotating the rotating ring 13 in the groove 12 drives the threaded rod 8 to rotate. Due to the threaded engagement between the threaded rod 8 and the threaded sleeve 9, and the sliding connection between the connecting square block 10 and the movable locking column 11 with the same width, the connecting square block 10 and the movable locking column 11 play a limiting role, preventing the threaded sleeve 9 from following the threaded rod 8. The rotation causes the threaded sleeve 9 to move axially along the threaded rod 8. The threaded sleeve 9 drives the movable locking pin 11 to move synchronously through the connecting square block 10. The movable locking pin 11 is inserted into the locking groove 4 of the fixed locking block 3 to achieve rigid locking. The connecting friction plate 14 is made of plastic, and the raised particles on its surface are embedded in the connecting groove 5 to provide additional friction, prevent lateral displacement between the fixed locking block 3 and the fixed locking groove 6, and ensure sufficient contact area after locking. The square groove 7 limits the connecting square block 10 to prevent the threaded sleeve 9 from rotating synchronously with the threaded rod 8.

[0032] During disassembly, the rotating ring 13 is rotated in the opposite direction to allow the movable locking post 11 to exit the locking groove 4 and release the rigid lock. Then, the fixed locking block 3 can be pulled out from the fixed locking groove 6. The elastic deformation characteristics of the connecting friction plate 14 allow it to separate from the connecting groove 5 without damage. This combined connecting device achieves a reliable connection between the steel frame lightweight plate 1 and the connecting post 2 through the dual effects of mechanical locking and friction enhancement. It also has the characteristics of being detachable and reusable.

[0033] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
