Description

Technical Field

[0001] This utility model relates to the field of building exterior wall panel technology, and in particular to a building exterior wall panel with high safety. Background Technology

[0002] Building exterior wall panels are a type of panel installed on the exterior facade of a building, serving both insulation and decorative purposes. Existing exterior wall panels are mainly fixed by screws or adhesives, which poses a risk of falling off if the panels are damaged or the fixing mechanism becomes loose.

[0003] To address this issue, the prior art, specifically the invention patent with authorization announcement number CN114482437B, provides a method for constructing an anti-falling concrete exterior wall insulation board. The board includes an insulation board body, an insulation layer, and a supporting frame. The outer surface of the insulation board body has a decorative layer, and an insulation layer is located on the side of the decorative layer away from the outer surface of the insulation board body. A concrete layer is located on the side of the insulation layer away from the decorative layer. A supporting frame is intersected in the middle of the concrete layer. Both the upper and lower ends of the insulation board body have mating interfaces for connection. The insulation board body is fixed to the mounting keel with screws, and the mounting keel is fixed to the building facade with screws. This method for constructing an anti-falling concrete exterior wall insulation board reduces the number of screws required while still enabling rapid installation of the concrete exterior wall insulation board. Furthermore, it provides a more secure fixation, effectively preventing the accidental fall of the concrete exterior wall insulation board.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: the patented technology only reduces the number of bolts, but bolts are still needed to fix the exterior wall panel to the wall. The wall surface is uneven. After the exterior wall panel is pressed and fixed to the wall surface with bolts, there will be a certain stress between the exterior wall panel and the wall. At the same time, thermal expansion and contraction will also cause the exterior wall panel itself to deform, generating stress between the exterior wall panel, the wall and the bolts. This stress will promote the aging and damage of the exterior wall panel. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a highly safe building exterior wall panel. This exterior wall panel can release stress within itself and between the panel and the building wall, reducing damage to the panel, extending its lifespan, and minimizing the risk of it falling off.

[0006] The technical solution to the technical problem solved by this utility model is as follows: An embodiment of this utility model provides a high-safety building exterior wall panel, installed on the outside of a building wall. It includes a panel body, an installation groove, a limiting frame, a guide block, and elastic elements. The installation groove is vertically installed inside the wall, with its front end flush with the outer surface of the wall. A vertical guide groove is provided in the installation groove, and the guide block is installed in the guide groove. A round rod is provided at one end of the guide block near the outer side of the wall. The limiting frame is installed on the round rod, and the end of the round rod has an external thread. Two nuts are installed at the end of the round rod. Elastic elements are provided on both the front and rear round rods of the limiting frame, and the elastic elements fit snugly against the limiting frame. U-shaped limiting grooves are provided on both sides of the limiting frame, and the panel body is inserted into the limiting grooves. Limiting frames are provided on both sides of the panel body, and there is a gap between the sides of the panel body and the bottom of the limiting grooves.

[0007] As an optimization, the mounting groove is either dovetail-shaped or T-shaped.

[0008] As an optimization, the guide groove is T-shaped, and a gasket is provided between the guide block and the guide groove. The gasket is an elastic rubber pad.

[0009] As an optimization, the front end of the limiting frame is also provided with a vertical slot, which is T-shaped with an open front end; the plate body includes a main body, reinforcing ropes, a fall arresting rope, and a stop ball. The reinforcing ropes are distributed longitudinally and transversely inside the main body, and the fall arresting rope is set on the outside of the main body. One end of the fall arresting rope is connected to the reinforcing rope, and the other end is connected to the stop ball. The stop ball is installed in the slot, the height of the slot is greater than the diameter of the stop ball, and the width of the slot is greater than twice the diameter of the stop ball. The fall arresting rope passes through the opening at the front end of the slot, and the width of the opening at the front end of the slot is less than the diameter of the stop ball and greater than twice the diameter of the fall arresting rope.

[0010] As an optimization, the top surface of the main body is convex, and the bottom surface of the main body is concave, corresponding to the top surface.

[0011] As an optimization, the plate and the limiting frame are staggered, and the seams between the limiting frames do not coincide with the seams between the plate.

[0012] As an optimization, the elastic element is a spring or a rubber sleeve.

[0013] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0014] 1. By setting elastic elements on the round rods at the front and rear of the limiting frame, the limiting frame and the plate can be displaced in the front-rear direction along the mounting groove; by setting limiting frames on both sides of the plate, there is a gap between the two sides of the plate and the bottom of the limiting groove, and the plate can be displaced in the left-right direction along the mounting groove, thereby releasing the stress of the plate itself and the building wall, reducing damage to the exterior wall panel, extending the service life of the exterior wall panel, and reducing the risk of the exterior wall panel falling off.

[0015] 2. By setting an elastic rubber gasket between the guide block and the guide groove, the gap between the guide block and the guide groove can be filled to improve the stability of the guide block. At the same time, the position of the guide block can be allowed to float to a certain extent, so as to adapt to the dimensional errors of the wall and the mounting groove. In conjunction with the elastic element, the limiting frames on both sides of the plate can be aligned in parallel, avoiding stress generated during the installation of the plate.

[0016] 3. By incorporating reinforcing ropes within the board and connecting them to a locking slot via a fall arrestor and ball bearing, when the board breaks, the broken pieces are suspended in the locking slot and slowly fall to the ground under their own weight, preventing the board from falling. The locking slot is sized to allow the upper ball bearing to pass through the area of ​​the lower ball bearing within the locking slot.

[0017] 4. By setting the top surface of the main body to be "convex" and the bottom surface of the main body to be "concave" corresponding to the top surface, the upper and lower panels can be connected by plugging, which improves the overall sturdiness of the exterior wall panel.

[0018] 5. By staggering the distribution of the panels and the limiting frames, the joints between the limiting frames and the joints between the panels do not overlap, which can improve the overall firmness of the exterior wall panels. Attached Figure Description

[0028] The components include: wall 1, plate 2, mounting groove 3, limiting frame 4, guide block 5, elastic element 6, nut 7, washer 8, main body 21, reinforcing rope 22, fall arresting rope 23, ball stop 24, guide groove 31, limiting groove 41, slot 42, and round rod 81. Detailed Implementation

[0029] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0030] Figures 1 to 8 As one embodiment of this utility model, such as Figure 4 , Figure 5 As shown, a high-safety building exterior wall panel is installed on the outside of the building wall 1. It includes a panel body 2, a mounting groove 3, a limiting frame 4, a guide block 5, and an elastic element 6. The mounting groove 3 is vertically installed inside the wall 1, and the front end of the mounting groove 3 is flush with the outer surface of the wall 1. A vertical guide groove 31 is provided in the mounting groove 3. The guide block 5 is installed in the guide groove 31. A round rod 81 is provided at one end of the guide block 5 near the outside of the wall 1. The limiting frame 4 is installed on the round rod 81. The end of the round rod 81 is provided with an external thread. Two nuts 7 are installed at the end of the round rod 81. Elastic elements 6 are provided on both the front and rear round rods 81 of the limiting frame 4. The elastic elements 6 fit with the limiting frame 4. U-shaped limiting grooves 41 are provided on both sides of the limiting frame 4. The panel body 2 is inserted into the limiting groove 41. The limiting frame 4 is provided on both sides of the panel body 2. There is a gap between the sides of the panel body 2 and the bottom of the limiting groove 41.

[0031] like Figure 5 As shown, the mounting groove 3 has a dovetail shape. The guide groove 31 is T-shaped, and a gasket 8, which is an elastic rubber pad, is provided between the guide block 5 and the guide groove 31. By providing the elastic rubber pad 8 between the guide block 5 and the guide groove 31, the gap between the guide block 5 and the guide groove 31 can be filled, improving the stability of the guide block 5. It also allows the position of the guide block 5 to have a certain degree of fluctuation, thereby adapting to the dimensional errors of the wall 1 and the mounting groove 3. Working in conjunction with the elastic element 6, it allows the limiting frames 4 on both sides of the plate 2 to be aligned in parallel, avoiding stress generated during the installation of the plate 2.

[0032] like Figure 4 As shown, the panel 2 and the limiting frame 4 are staggered, and the joints between the limiting frames 4 do not coincide with the joints between the panels 2. By staggering the panel 2 and the limiting frame 4, and ensuring that the joints between the limiting frames 4 do not coincide with the joints between the panels 2, the overall strength of the exterior wall panel can be improved.

[0033] like Figure 5 As shown, the front end of the limiting frame 4 is also provided with a vertical slot 42, which is T-shaped with an opening at the front end. Figure 7 , Figure 8 As shown, the plate 2 includes a main body 21, reinforcing ropes 22, a fall arresting rope 23, and a bob 24. The reinforcing ropes 22 are distributed longitudinally and transversely inside the main body 21, while the fall arresting rope 23 is located outside the main body 21. One end of the fall arresting rope 23 is connected to the reinforcing rope 22, and the other end is connected to the bob 24. The bob 24 is installed in a slot 42, the height of which is greater than the diameter of the bob 24, and the width of which is greater than twice the diameter of the bob 24. The fall arresting rope 23 passes through an opening at the front end of the slot 42, the width of which is less than the diameter of the bob 24 but greater than twice the diameter of the fall arresting rope 23. By installing the reinforcing ropes 22 in the plate 2 and connecting them to the slot 42 via the fall arresting rope 23 and the bob 24, when the plate 2 breaks, the broken pieces of the plate 2 will be suspended in the slot 42 and slowly fall to the ground under their own weight, thus avoiding the danger of the plate 2 falling. The size of the slot 42 allows the upper stop ball 24 to pass through the area of ​​the slot 42 where the lower stop ball 24 is located. The elastic element 6 is a spring.

[0034] like Figure 6 As shown, the top surface of the main body 21 is convex, and the bottom surface of the main body 21 is concave, corresponding to the top surface. By setting the top surface of the main body 21 to be convex and the bottom surface of the main body 21 to be concave, the upper and lower panels 2 can be connected by plugging, which improves the overall sturdiness of the exterior wall panel.

[0035] By setting elastic elements 6 on the round rods 81 before and after the limiting frame 4, the limiting frame 4 and the plate 2 can be displaced in the front and back direction along the mounting groove 3; by setting the limiting frame 4 on both sides of the plate 2, there is a gap between the two sides of the plate 2 and the bottom of the limiting groove 41, and the plate 2 can be displaced in the left and right direction along the mounting groove 3, thereby releasing the stress of the plate 2 itself and between it and the building wall, reducing damage to the exterior wall panel, extending the life of the exterior wall panel, and reducing the risk of the exterior wall panel falling off.

[0036] Figure 9 This is the second embodiment of the present invention, which differs from the first embodiment in that the mounting groove 3 is T-shaped.

[0037] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
