Description

Technical Field

[0001] This application relates to the field of building exterior wall reinforcement technology, and in particular to a building exterior wall reinforcement and renovation structure. Background Technology

[0002] As buildings age, materials such as concrete and steel bars gradually deteriorate, leading to a decrease in load-bearing capacity and potential safety hazards. Therefore, it is necessary to design a structure that can improve the stability of building exterior walls.

[0003] Chinese Patent No. CN213927618U discloses a wall reinforcement device for building renovation construction, which includes an exterior wall reinforcement frame and an external scaffold. The exterior wall reinforcement frame includes an inner reinforcement frame and an outer reinforcement frame, which are fixedly connected to each other by a number of through-wall bolts. The external scaffold is connected to the outer reinforcement frame. This utility model provides an exterior wall reinforcement device that forms a protective structure for the exterior wall through the exterior wall reinforcement frame and external scaffold, improving construction safety. Furthermore, both the exterior wall reinforcement frame and the external scaffold can be quickly assembled using standard components, improving construction efficiency.

[0004] Regarding the aforementioned technologies, existing technologies use internal and external reinforcing frames, along with through-wall bolts and U-shaped clips, to tighten the inner and outer walls of the exterior wall, thereby improving its stability. However, during installation, workers need to install the through-wall bolts, reinforcing longitudinal bars, reinforcing transverse bars, and U-shaped clips on-site in sequence. The hoisting of the reinforcing transverse bars and reinforcing longitudinal bars, as well as the on-site installation of components such as U-shaped clips and through-wall bolts, all require on-site support from workers. This increases the installation steps and difficulty of the reinforcement device, and reduces the installation efficiency of the exterior wall reinforcement device. Summary of the Invention

[0005] In order to improve the installation efficiency of external wall reinforcement structures, this application provides a building external wall reinforcement and renovation structure.

[0006] This application provides the following technical solution for the structural reinforcement and renovation of building exterior walls:

[0007] A building exterior wall reinforcement and renovation structure includes a reinforcement component installed on the exterior wall. The reinforcement component includes a connecting seat, a pressure block, a pressure plate, a fastening column, a stabilizing column, and a clamping nut. Four connecting seats are detachably connected to the exterior wall. One stabilizing column is installed between two adjacent connecting seats and fits against the exterior wall. Both ends of the stabilizing column are connected to connecting blocks. The connecting blocks are inserted into the connecting seats. The pressure plate is slidably fitted on the connecting seats and presses against the connecting blocks. The fastening column is connected to the connecting seats. The pressure block passes through the fastening column and presses against the pressure plate. The clamping nut is threaded onto the fastening column and applies pressure to the pressure block. A rectangular frame is formed between the fastening column and the connecting seats.

[0008] By adopting the above technical solution, during assembly, the connecting blocks are inserted into the connecting seats, causing the pressure plate to press the connecting blocks. Rotating the clamping nut further presses the pressure blocks against the pressure plate, forming a rectangular frame between several stabilizing columns and four connecting seats. Finally, the rectangular frame is installed on the exterior wall, ensuring the stabilizing columns fit against the exterior wall surface, thus realizing the installation of the building's exterior wall reinforcement structure. The cooperation of several stabilizing columns and connecting seats forms a complete frame, further improving the shear resistance and overall stability of the exterior wall through the overall stability of the frame. Workers pre-assemble the rectangular frame using the various components of the reinforcement assembly. During exterior wall reinforcement, the entire rectangular frame is then installed on the exterior wall surface. This way, workers only need to reinforce the connecting seats on-site, resulting in fewer, faster, and less difficult on-site installation steps, significantly improving the installation efficiency of the exterior wall reinforcement structure compared to existing technologies.

[0009] Optionally, each of the two intersecting fastening columns has an assembly groove, and the two fastening columns cooperate through the assembly groove. After assembly, the two fastening columns are flush and both fit against the exterior wall.

[0010] By adopting the above technical solution and setting the assembly groove, the two intersecting fastening columns are set on the same plane and both are attached to the outer wall. This maximizes the contact area between the rectangular frame and the outer wall and improves the stability of the outer wall.

[0011] Optionally, a stabilizing plate is provided between the two staggered fastening columns. The stabilizing plate has a cross-shaped channel through which the fastening columns pass, and the stabilizing plate is connected to the exterior wall.

[0012] By adopting the above technical solution and setting a stabilizing plate to further limit the relative position between the two staggered fastening columns, the structural strength of the middle part of the exterior wall is further improved.

[0013] Optionally, the connecting seat is connected to a plurality of limiting posts, and the pressure plate is slidably fitted between the plurality of limiting posts.

[0014] By adopting the above technical solution and setting limiting columns, the movement direction of the pressure plate is limited on the one hand, and the stability of the pressure plate pressing the connecting block is improved on the other hand.

[0015] Optionally, the fastening post is threaded with an anti-loosening nut, which abuts against the clamping nut.

[0016] By adopting the above technical solution, the exterior wall will be affected by vibration, and there is a possibility that the clamping nuts may be loosened. By installing anti-loosening nuts, the possibility of the clamping nuts being loosened by vibration is reduced.

[0017] Optionally, the connecting block has a clamping groove with an inclined bottom wall. A clamping block is connected to the pressure plate with a pressure-applying inclined surface. The thickness of the clamping block gradually increases from the pressure block to the stabilizing column as a reference direction. The pressure-applying inclined surface fits the bottom wall of the clamping groove, and a gap is left between the pressure plate and the connecting block.

[0018] By adopting the above technical solution, and by setting the clamping groove and clamping block, when the connecting block is pressed, the connecting block tends to move towards the pressing block position, so that the fastening column further presses against the connecting seat, thereby improving the stability of the entire reinforcement structure.

[0019] Optionally, an extension block is connected to the pressure block at the position corresponding to the connecting block, and a limiting groove is opened on the pressure plate, with the extension block partially embedded in the limiting groove.

[0020] By adopting the above technical solution, when the clamping nut clamps the pressure block, the extension block clamps the pressure plate. At this time, the extension block may deform and slip against the pressure plate. Through the cooperation of the extension block and the limiting groove, the movement of the extension block is restricted. Even if the extension block deforms, it always applies pressure to the pressure plate at the limiting groove, thereby improving the assembly stability of the connecting block.

[0021] Optionally, a waterproof layer is provided on the exterior wall surface.

[0022] By adopting the above technical solution, the waterproof layer reduces the possibility of moisture penetrating the exterior wall and extends the service life of the exterior wall.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During assembly, the connecting blocks are inserted into the connecting seats, and the pressure plate applies pressure to the connecting blocks. The tightening nut is then rotated, causing the pressure blocks to press against the pressure plate, forming a rectangular frame between the stabilizing columns and the four connecting seats. Finally, the rectangular frame is installed on the exterior wall, ensuring the stabilizing columns are flush with the exterior wall surface, thus completing the installation of the building's exterior wall reinforcement structure. The cooperation of several stabilizing columns and connecting seats forms a unified frame, further improving the shear resistance and overall stability of the exterior wall through the overall stability of the frame. Workers pre-assemble the rectangular frame using the various components of the reinforcement assembly. During exterior wall reinforcement, the entire rectangular frame is then installed on the exterior wall surface. This reduces the number of on-site installation steps, making the process quicker, easier, and less complex compared to existing technologies, significantly improving the installation efficiency of the exterior wall reinforcement structure.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses a structure for reinforcing and renovating building exterior walls. (Refer to...) Figure 1 and Figure 2 The building exterior wall reinforcement and renovation structure includes a reinforcement component 1 installed on the exterior wall 01. The reinforcement component 1 includes a connecting seat 11, a pressure block 12, a pressure plate 13, a fastening column 14, a stabilizing column 15, and a clamping nut 16. Four connecting seats 11 are installed on the exterior wall 01 by expansion bolts, and the four connecting seats 11 are arranged at the four corners.

[0032] Reference Figure 1 and Figure 2One stabilizing post 15 is provided between each two adjacent connecting seats 11. Both ends of the stabilizing post 15 are fixedly connected to connecting blocks 151. Three insertion slots are opened on the connecting seats 11, and the connecting blocks 151 are inserted into the insertion slots. A clamping groove is opened on the side wall of the connecting block 151 away from the connecting seat 11, and the bottom wall of the clamping groove is inclined.

[0033] Reference Figure 2 and Figure 3 A number of limiting posts 111 are fixedly connected to the connecting seat 11. In this embodiment, two posts are used as an example. The pressure plate 13 is slidably fitted between the two limiting posts 111. The limiting posts 111 are used to improve the stability of the pressure plate 13 during assembly. A retaining block 131 is fixedly connected to the pressure plate 13 at the position corresponding to the retaining groove. The retaining block 131 is provided with a retaining slope. Taking the connecting seat 11 to the stabilizing post 15 as a reference direction, the thickness of the retaining block 131 gradually increases, and the retaining slope fits against the bottom wall of the retaining groove.

[0034] Reference Figure 2 and Figure 3 The fastening post 14 is fixedly connected to the connecting seat 11, and the pressure block 12 is sleeved on the fastening post 14. An extension block 121 is integrally formed on the pressure block 12 at a position corresponding to the connecting block 151. A limiting groove 132 is formed on the pressure plate 13, and part of the extension block 121 is embedded in the limiting groove 132. The clamping nut 16 is threaded onto the fastening post 14 and abuts against the clamping nut 16. The anti-loosening nut 161 is used to reduce the possibility of the clamping nut 16 being loosened by vibration.

[0035] Reference Figure 1 and Figure 4 There are assembly slots 152 between the two intersecting fastening posts 14. The two fastening posts 14 are engaged through the assembly slots 152 so that the two fastening posts 14 are on the same plane.

[0036] Reference Figure 1 and Figure 4 A rectangular frame is formed between the four connecting seats 11 and the six stabilizing columns 15. The connecting seats 11 are connected to the outer wall 01 by expansion bolts. A stabilizing plate 2 is provided between two staggered stabilizing columns 15. A cross channel 21 is provided on the stabilizing plate 2. The two stabilizing columns 15 pass through the cross channel 21. The stabilizing plate 2 is connected to the outer wall 01 by expansion bolts.

[0037] Reference Figure 1 To further improve the service life of exterior wall 01, a waterproof layer is provided on the surface of exterior wall 01. The waterproof layer is a waterproof coating, such as polyurethane waterproof coating.

[0038] The implementation principle of the building exterior wall reinforcement and renovation structure in this application embodiment is as follows: During installation, the connecting block 151 is inserted into the connecting seat 11, so that a rectangular frame is formed between the connecting seat 11 and the stabilizing column 15. The pressing block 131 on the pressure plate 13 presses against the bottom wall of the groove. Then, the clamping nut 16 is rotated so that the extension block 121 presses against the pressure plate 13. Then, the anti-loosening nut 161 is rotated to press the clamping nut 16. The four connecting seats 11 are connected to the exterior wall 01 by expansion bolts. Finally, the stabilizing plate 2 is sleeved between the two staggered stabilizing columns 15 and fixed with expansion bolts, thus realizing the installation of the exterior wall 01 reinforcement structure.

[0039] Workers assemble a rectangular frame using the various components of reinforcement component 1 beforehand. When reinforcing the exterior wall 01, the entire rectangular frame is then installed on the surface of the exterior wall 01. In this way, workers only need to reinforce the connecting seat 11 on site. The entire on-site installation process is simple, quick, and easy, which improves the installation efficiency of the exterior wall 01 reinforcement structure compared to existing technologies.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
