Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, and in particular to a prefabricated assembly structure for connecting exterior walls and insulation walls. Background Technology

[0002] With the development of modern industrial technology, building houses can now be mass-produced like machine manufacturing. Prefabricated building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. This is prefabricated construction. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they employ standardized design, factory production, assembly-based construction, information management, and intelligent applications, they represent modern industrialized production methods. Prefabricated buildings offer fast construction speeds and lower production costs, leading to their rapid global adoption. Early prefabricated buildings had relatively simple structural designs; however, with continuous technological advancements, prefabricated construction has undergone significant changes, and prefabricated building components have become increasingly diverse.

[0003] To improve insulation in buildings, two layers of reinforced concrete wall panels are typically used, with an insulation wall installed between them. The exterior wall panels and the insulation wall panels are usually connected and fixed using adhesive bonding. However, this connection method is prone to gaps, causing the exterior wall panels to easily detach from the insulation wall panels, thus affecting the quality of the wall installation. Summary of the Invention

[0004] In order to effectively improve the installation quality of the wall, this application provides a prefabricated assembled exterior wall and insulation wall connection structure.

[0005] The purpose of this application is to provide a prefabricated assembled exterior wall and insulation wall connection structure, which adopts the following technical solution:

[0006] A prefabricated assembly-type exterior wall and insulation wall connection structure includes connecting ribs, connecting grooves, and auxiliary components disposed within the insulation wall panel. The connecting ribs are fixedly connected to the side of the exterior wall panel facing the insulation wall panel, and the connecting grooves are formed on the side of the insulation wall panel facing the exterior wall panel. The connecting ribs and the connecting grooves are inserted into each other. A connecting hook is slidably connected to the end face of the connecting ribs away from the exterior wall panel, and a connecting rod is fixedly connected to the groove wall of the connecting groove. The auxiliary components are used to push the connecting hooks to move so that the connecting hooks are sleeved on the connecting rods.

[0007] By adopting the above technical solution, the prefabricated exterior wall panel is attached to the insulation wall panel so that the connecting rib is inserted into the connecting groove; then, the connecting hook is moved by the auxiliary component so that the connecting hook is sleeved on the outside of the connecting rod, thereby quickly and stably connecting the exterior wall panel to the insulation wall panel, thus improving the installation quality of the wall.

[0008] Optionally, the connection structure further includes an I-beam groove and an I-beam connector. The I-beam groove is formed on the left and right end faces of the exterior wall panel and the insulation wall panel, and the I-beam connector is inserted into the I-beam groove.

[0009] By adopting the above technical solution, the I-beam connector and the I-beam groove can be used to connect the mutually abutting exterior wall panels and insulation wall panels together, thereby reducing the possibility of the exterior wall panels falling off the insulation wall panels and improving the installation quality of the wall.

[0010] Optionally, the auxiliary component includes a connecting hole and a connecting rod. The connecting hole is formed inside the insulation wall panel and is connected to the connecting groove and the I-shaped groove respectively. The connecting rod is slidably connected inside the connecting hole.

[0011] By adopting the above technical solution, during the insertion of the I-beam connector into the I-beam groove from above, the I-beam connector will press against the connecting rod and move within the connecting hole, pushing the two connecting hooks closer together so that the connecting hooks are sleeved on the outside of the connecting rod, thereby quickly and stably connecting the exterior wall panel to the insulation wall panel. The I-beam connector, in conjunction with the I-beam groove, can reduce the gap between two adjacent insulation wall panels, thus improving the insulation effect of the wall insulation layer; at the same time, it can also reduce the gap between two adjacent exterior wall panels, thereby reducing the penetration of rainwater, dust, and other impurities into the insulation layer, which helps to extend the service life of the insulation wall panel.

[0012] Optionally, the end face of the connecting rod away from the connecting rod is an upwardly inclined surface.

[0013] By adopting the above technical solution and the shape setting of the connecting rod, during the process of inserting the I-beam connector into the I-beam groove from above, the bottom end of the I-beam connector will press against the inclined surface of the connecting rod to push the connecting rod to move within the connecting hole.

[0014] Optionally, the I-beam connector is made of glass fiber.

[0015] By adopting the above technical solution, glass fiber has good heat insulation properties, thereby improving the heat insulation effect of the wall insulation layer.

[0016] Optionally, a sliding groove is provided on the end face of the connecting rib away from the outer wall panel, and a sliding block that slides and cooperates with the sliding groove is fixedly connected to the connecting hook; a first spring is provided between the two sliding blocks, and the two ends of the first spring are respectively fixedly connected to the two sliding blocks.

[0017] By adopting the above technical solution, the first spring can separate the two sliding blocks so that the distance between the free ends of the two connecting hooks is greater than the diameter of the connecting rod, which facilitates the insertion of the connecting rib into the connecting groove so that the two connecting hooks are inserted from both sides of the connecting rod; then the connecting rod pushes the two connecting hooks together so that the connecting hooks are sleeved on the outside of the connecting rod.

[0018] Optionally, the connection structure further includes a movable groove, a plug strip, and a plug slot. The movable groove is formed on the upper surface of the insulation wall panel, and the plug strip is slidably connected in the movable groove. The plug slot is formed on the upper surface of the insulation wall panel, and the plug strip is plugged into the plug slot on the adjacent insulation wall panel.

[0019] By adopting the above technical solution, the bottom of the movable connector strip is inserted into the connector groove of the lower insulation wall panel, which can reduce the gap between two adjacent insulation wall panels, thereby improving the insulation effect of the wall insulation layer.

[0020] Optionally, the connection structure further includes a linkage hole and a linkage rod. The linkage hole is opened inside the insulation wall panel and is connected to the moving groove and the connecting groove respectively. One end of the linkage rod is fixedly connected to the plug-in strip, and the other end of the linkage rod is fixedly connected to a push block. The surface of the push block away from the linkage rod is an inclined surface, and the inclined surface of the push block faces away from the connecting rod. The side of the connecting hook abuts against the inclined surface of the push block. A second spring is sleeved on the linkage rod. One end of the second spring is fixedly connected to the linkage rod, and the other end of the second spring is fixedly connected to the push block.

[0021] By adopting the above technical solution, the second spring can make the bottom of the plug strip located in the moving groove, which makes it easy for the upper and lower insulation wall panels to stick together; when the two connecting hooks come close to each other, the connecting hooks will abut against the inclined surface of the push block, so that the linkage rod and the plug strip move downward, thereby inserting the bottom of the plug strip into the plug groove of the lower insulation wall panel, so as to improve the insulation effect of the wall insulation layer.

[0022] Optionally, the cross-section of the connector strip is isosceles, and the connector groove corresponds to the connector strip.

[0023] By adopting the above technical solution and the shape of the connector strip, the bottom of the connector strip is easier to insert into the connector groove, thereby making the connection between the upper and lower insulation wall panels faster.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The prefabricated exterior wall panel is attached to the insulation wall panel so that the connecting ribs are inserted into the connecting groove; then the connecting hook is moved by the auxiliary component so that the connecting hook is sleeved on the outside of the connecting rod, thereby quickly and stably connecting the exterior wall panel to the insulation wall panel to improve the installation quality of the wall.

[0026] 2. As the I-beam connector is inserted into the I-beam groove from above, it presses against the connecting rod and moves within the connecting hole, pushing the two connecting hooks closer together. This allows the connecting hooks to engage with the connecting rod, thus quickly and stably connecting the exterior wall panel to the insulation wall panel. The I-beam connector, in conjunction with the I-beam groove, reduces the gap between two adjacent insulation wall panels, thereby improving the insulation effect of the wall insulation layer. Simultaneously, reducing the gap between two adjacent exterior wall panels reduces the penetration of rainwater, dust, and other impurities into the insulation layer, facilitating a longer service life for the insulation wall panel.

[0032] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-4 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0033] This application discloses a prefabricated assembly-type external wall and insulation wall connection structure. (Refer to...) Figure 1 and Figure 2 The connecting mechanism includes an I-beam groove 8 and an I-beam connector 9. The I-beam groove 8 is formed on the left and right end faces of the exterior wall panel 5 and the insulation wall panel 4. The I-beam connector 9 is inserted into the I-beam groove 8. The I-beam connector 9, in cooperation with the I-beam groove 8, can connect the abutting exterior wall panel 5 and the insulation wall panel 4 together, thereby reducing the possibility of the exterior wall panel 5 detaching from the insulation wall panel 4 and improving the installation quality of the wall.

[0034] It should be noted that the exterior wall panel 5 is precast with reinforced concrete, while the insulation wall panel 4 is made of insulation material. The grooves on the sides of the exterior wall panel 5 in the width direction are assembled with the corresponding grooves on the sides of the insulation wall panel 4 in the width direction to form an I-beam groove 8. The grooves on the exterior wall panel 5 can be pre-cast during the precast process, while the grooves on the insulation wall panel 4 can be created during manufacturing. The I-beam connector 9 is made of fiberglass and is vertically arranged. Fiberglass has excellent heat-insulating properties, thereby improving the insulation effect of the wall insulation layer.

[0035] Reference Figure 2 and Figure 3 The connecting mechanism also includes a connecting rib 1, a connecting groove 2, and an auxiliary component 3 installed within the insulated wall panel 4. The connecting rib 1 is fixedly connected to the side of the outer wall panel 5 facing the insulated wall panel 4, and the connecting groove 2 is opened on the side of the insulated wall panel 4 facing the outer wall panel 5. The connecting rib 1 and the connecting groove 2 are interlocked. The connecting rib 1 is made of fiberglass and can be tied to the reinforcing cage of the outer wall panel 5 with steel wire, after which concrete is poured over the reinforcing cage and the connecting rib 1. The connecting groove 2 can be opened during the fabrication of the insulated wall panel 4.

[0036] It should be noted that in other embodiments, during the pre-casting of the exterior wall panel 5, threaded holes can be pre-drilled on the side of the exterior wall panel 5, and the end of the connecting rib 1 is integrally formed with a threaded rod, which is threadedly engaged with the threaded hole. The engagement of the threaded rod with the threaded hole allows the connecting rib 1 to be detachably connected to the exterior wall panel 5. Removing the connecting rib 1 from the exterior wall panel 5 makes the transportation and handling of the exterior wall panel 5 more convenient; after transporting the exterior wall panel 5 to the construction site, the connecting rib 1 is then fixed to the side of the exterior wall panel 5.

[0037] Reference Figure 2 and Figure 3A connecting hook 6 is slidably connected to the end face of the connecting rib 1 away from the outer wall panel 5, and a connecting rod 7 is fixedly connected to the groove wall of the connecting groove 2. A sliding groove 10 is formed on the end face of the connecting rib 1 away from the outer wall panel 5. The sliding groove 10 has a convex cross-section and can be created during the fabrication of the connecting rib 1. Two sliding blocks 11 are fixedly connected to the connecting hook 6 by welding, and the sliding blocks 11 slide and engage with the sliding groove 10. The connecting rod 7 is made of fiberglass, meaning it can be integrally formed during the fabrication of the insulation wall panel 4. The sliding blocks 11 and the sliding groove 10 cooperate to guide the movement of the connecting hook 6, allowing the two connecting hooks 6 to better fit onto the connecting rod 7.

[0038] Reference Figure 2 and Figure 3 To allow the two connecting hooks 6 to insert from both sides of the connecting rod 7, a first spring 12 is installed between the two sliding blocks 11. The two ends of the first spring 12 are fixed to the two sliding blocks 11 by welding. The first spring 12 allows the two sliding blocks 11 to separate, so that the distance between the free ends of the two connecting hooks 6 is greater than the diameter of the connecting rod 7. This facilitates the insertion of the connecting rib tube 1 into the connecting groove 2, allowing the two connecting hooks 6 to insert from both sides of the connecting rod 7. Then, the connecting rod 32 pushes the two connecting hooks 6 closer together, thereby fitting the connecting hooks 6 onto the outside of the connecting rod 7.

[0039] It should be noted that in other embodiments, the connecting hook 6 can be hinged to the connecting rib 1, and a torsion spring is sleeved on the hinge shaft of the connecting hook 6. One end of the torsion spring is fixedly connected to the connecting hook 6, and the other end of the torsion spring is fixedly connected to the connecting rib 1. When the torsion spring is in its natural state, the distance between the free ends of the two connecting hooks 6 is greater than the diameter of the connecting rod 7.

[0040] Reference Figure 2 and Figure 3 To quickly and stably connect the exterior wall panel 5 to the insulation wall panel 4, an auxiliary component 3 is used to push the connecting hook 6 to move so that the connecting hook 6 is sleeved on the outside of the connecting rod 7. The auxiliary component 3 includes a connecting hole 31 and a connecting rod 32. The connecting hole 31 is opened in the insulation wall panel 4 and is connected to the connecting groove 2 and the I-shaped groove 8 respectively. The connecting rod 32 is slidably connected in the connecting hole 31. The connecting hole 31 can be reserved during the manufacturing of the insulation wall panel 4. The end face of the connecting rod 32 away from the connecting rod 7 is an upward inclined surface. The other end of the connecting rod 32 can abut against the outer side of the connecting hook 6. Due to the shape of the connecting rod 32, when the I-shaped connector 9 is inserted into the I-shaped groove 8 from above, the bottom end of the I-shaped connector 9 will press against the inclined surface of the connecting rod 32 to push the connecting rod 32 to move in the connecting hole 31.

[0041] It should be noted that during the process of inserting the I-beam connector 9 into the I-beam groove 8 from above, the I-beam connector 9 will press against the connecting rod 32 and move within the connecting hole 31, pushing the two connecting hooks 6 closer together so that the connecting hooks 6 are sleeved on the outside of the connecting rod 7, thereby quickly and stably connecting the exterior wall panel 5 to the insulation wall panel 4. The I-beam connector 9, in cooperation with the I-beam groove 8, can reduce the gap between two adjacent insulation wall panels 4, thereby improving the insulation effect of the wall insulation layer; at the same time, it can also reduce the gap between two adjacent exterior wall panels 5, thereby reducing the penetration of rainwater, dust and other impurities into the insulation layer, which helps to extend the service life of the insulation wall panel 4.

[0042] Reference Figure 4 To improve the insulation effect of the wall insulation layer, the connection structure also includes a movable groove 13, a plug strip 14, and a plug groove 15. The movable groove 13 is located on the upper surface of the insulation wall panel 4, and the plug strip 14 is slidably connected within the movable groove 13. The plug groove 15 is located on the upper surface of the insulation wall panel 4, and the plug strip 14 is plugged into the plug groove 15 on the adjacent insulation wall panel 4. The movable groove 13 and the plug groove 15 can be pre-reserved during the manufacturing of the insulation wall panel 4. The plug strip 14 is made of fiberglass, and its cross-section is isosceles. The plug groove 15 corresponds to the plug strip 14. The shape of the plug strip 14 makes it easier for its bottom to be inserted into the plug groove 15. Moving the plug strip 14 allows its bottom to be inserted into the plug groove 15 of the lower insulation wall panel 4, which reduces the gap between two adjacent insulation wall panels 4, thereby improving the insulation effect of the wall insulation layer.

[0043] Reference Figure 4 To improve the insulation effect of the wall insulation layer, the connection structure also includes a linkage hole 16 and a linkage rod 17. The linkage hole 16 is opened inside the insulation wall panel 4 and is connected to the moving groove 13 and the connecting groove 2 respectively. One end of the linkage rod 17 is fixed to the plug-in strip 14 by welding, and the other end of the linkage rod 17 is fixed to the push block 18 by welding. The surface of the push block 18 away from the linkage rod 17 is an inclined surface, and the inclined surface of the push block 18 faces away from the connecting rod 7. The side of the connecting hook 6 abuts against the inclined surface of the push block 18. A second spring 19 is sleeved on the linkage rod 17. One end of the second spring 19 is fixed to the linkage rod 17 by welding, and the other end of the second spring 19 is fixed to the push block 18 by welding. The linkage hole 16 can be reserved during the manufacturing of the insulation wall panel 4.

[0044] It should be noted that the second spring 19 allows the bottom of the connector strip 14 to be located in the moving groove 13, which facilitates the upper and lower insulation wall panels 4 to be attached together. When the two connecting hooks 6 come close to each other, the connecting hooks 6 will abut against the inclined surface of the push block 18, so that the linkage rod 17 and the connector strip 14 move downward, thereby inserting the bottom of the connector strip 14 into the connector groove 15 of the lower insulation wall panel 4, so as to improve the insulation effect of the wall insulation layer.

[0045] The implementation principle of a prefabricated assembled exterior wall and insulation wall connection structure in this application embodiment is as follows: The prefabricated exterior wall panel 5 is attached to the insulation wall panel 4, so that the connecting rib 1 is inserted into the connecting groove 2; then, the I-beam connector 9 is inserted into the I-beam groove 8 from above the insulation wall panel 4 and the exterior wall panel 5. The bottom end of the I-beam connector 9 presses against the inclined surface of the connecting rod 32, pushing the connecting rod 32 to move within the connecting hole 31. The movement of the connecting rod 32 will push the two connecting hooks 6 closer together, so that the two connecting hooks 6 are sleeved on the outside of the connecting rod 7, facilitating better fixation of the exterior wall panel 5 to the insulation wall panel 4. When the two connecting hooks 6 are close together, the bottom of the connecting hook 6 will abut against the inclined surface of the pushing block 18, causing the linkage rod 17 and the insertion strip 14 to move downwards, thereby inserting the bottom of the insertion strip 14 into the insertion groove 15 of the lower insulation wall panel 4, which facilitates improving the insulation effect of the wall insulation layer.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar alternative features unless specifically stated otherwise. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
