Description

Technical Field

[0001] The utility model belongs to the technical field of building reinforcement, and more specifically, particularly relates to a building exterior wall reinforcement structure. Background Technique

[0002] The renovation of old cities is to transform and update all the physical living environments of old cities, partially or integrally and step by step, including urban roads, road networks, water and electricity, and communication, and fundamentally improve their fire protection, travel, production, labor, life, service, and rest conditions. It not only reflects the development process of the city, the urban spatial planning organization, and the improvement process of buildings and social welfare facilities, but also represents the material achievements and reflects the status of buildings and welfare facilities at that time. The renovation of old cities is an uninterrupted process, which depends on the development direction and speed of the city. For some buildings in the old city area, the method of demolition and reconstruction is adopted, but for some other buildings with less serious damage, or those that need to be retained and protected, their structures need to be strengthened by steel structures. The relevant technical solutions are as follows:

[0003] For example, a wall reinforcement structure with the application number CN201910293850.8. The embodiment of the present invention provides a wall reinforcement structure, including an upper floor slab and a lower floor slab, and further including an energy dissipation plate, a plurality of first connecting rods, and a plurality of second connecting rods; the upper floor slab is connected to the top of the shear wall, and the lower floor slab is connected to the bottom of the shear wall; the bottoms of the plurality of first connecting rods are all connected to the top of the energy dissipation plate, and the tops of the plurality of first connecting rods are all connected to the upper floor slab; the tops of the plurality of second connecting rods are all connected to the bottom of the energy dissipation plate, and the bottoms of the plurality of second connecting rods are all connected to the lower floor slab. The wall reinforcement structure provided by the embodiment of the present invention, while increasing the deformation and energy dissipation capacity of the shear wall, does not change the stiffness of the shear wall, making the wall reinforcement structure more in line with seismic design, reducing the damage degree of the shear wall under earthquake action, and protecting the safety and applicability of the existing main structure. It mainly enhances the anti-destruction ability of the wall, but does not consider how to repair the wall in the case of wall damage.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that the connection between the prior art and the wall mainly relies on connecting rods to tighten the angle steels at both ends, so as to clamp and fix the wall between the angle steels, thereby achieving the purpose of enhancing the wall structure. However, this structure makes the stability of the wall in the middle area between the two angle steels poor, thus affecting the overall stability of the wall.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and its deficiencies, and a building exterior wall reinforcement structure is provided, with the expectation of achieving a more practical value purpose. Content of the Utility Model

[0006] To solve the above technical problems, the present utility model provides a building exterior wall reinforcement structure to solve the problem that the connection with the wall in the prior art mainly relies on connecting rods to tighten the angle steels at both ends, thereby clamping and fixing the wall between the angle steels to enhance the wall structure.

The inner clamping member and the outer clamping member are both provided with a plurality of through holes, and through holes corresponding to the through holes are provided on the wall.

[0010] A bolt connecting member that passes through the through holes and the through holes to fixedly connect the inner clamping member and the outer clamping member to the wall.

[0011] Further, the bolt connecting member includes a bidirectional screw rod, a first nut, and a second nut. Threaded portions are respectively provided at both ends of the bidirectional screw rod, and the first nut and the second nut are respectively threadedly connected to the threaded portions at both ends of the bidirectional screw rod.

[0012] Further, the outer clamping member is further provided with a plurality of side ears. Threaded holes are provided on the side ears. An outer decorative plate is provided on the outside of the outer clamping member.

[0015] Further, the inner clamping member and the outer clamping member are metal plates, and a plurality of weight-reducing holes are provided on the metal plates.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0028] Embodiment:

[0029] As shown in the attached Figure 1 to the attached Figure 5 figures:

[0030] The present utility model provides a building exterior wall reinforcement structure, including:

[0031] An inner clamping member 11 and an outer clamping member 12 respectively clamped on the inner surface and the outer surface of the wall 17. Both the inner clamping member 11 and the outer clamping member 12 are provided with a plurality of through holes 121, and through holes 171 corresponding to the through holes 121 are provided on the wall 17;

[0032] A bolt connecting member 13, the bolt connecting member 13 passes through the through holes 121 and the through holes 171 to fixedly connect the inner clamping member 11 and the outer clamping member 12 to the wall 17.

[0033] In this embodiment, by providing the inner clamping member 11 and the outer clamping member 12 to clamp and fix the wall 17 therebetween, the reinforcement of the wall is realized. Since the bolt connecting member 13 applies a fastening force to the inner clamping member 11 and the outer clamping member 12, the inner clamping member 11, the outer clamping member 12 and the wall 17 are clamped and fixed into a whole, with relatively high stability. At the same time, since a plurality of bolt connecting members 13 are arranged in an array, it is ensured that the middle area of the wall 17 also has a strong effect of resisting lateral stress.

[0034] The bolt connection member 13 includes a bidirectional screw 131, a first nut 132, and a second nut 133. Threaded portions are respectively provided at both ends of the bidirectional screw 131, and the first nut 132 and the second nut 133 are respectively threadedly connected to the threaded portions at both ends of the bidirectional screw 131.

[0035] The bidirectional screw 131 provided in the bolt connection member 13 can pass through the through hole 121 and the through hole 171, and the first nut 132 and the second nut 133 are locked at both ends of the bidirectional screw 131, thereby playing a fastening role.

[0036] The outer clamping member 12 is further provided with a plurality of side ears 122. Threaded holes are provided in the side ears 122. An outer decorative plate 16 is provided on the outside of the outer clamping member 12. Connection ears 161 are provided on the outer decorative plate 16 corresponding to the side ears 122. Through holes are provided in the connection ears 161 corresponding to the threaded holes, and bolts pass through the through holes and are threadedly connected to the threaded holes.

[0037] The function of providing the side ears 122 on the outer clamping member 12 is to facilitate the installation of the outer decorative plate 16.

[0038] A foam board 14 is fixedly connected to the inner side of the inner clamping member 11. The foam board 14 is provided with an avoidance hole 141 corresponding to the position of the second nut 133.

[0039] The foam board 14 can further improve the overall sound insulation and heat insulation performance of the wall.

[0040] An inner decorative plate 15 is fixedly connected to the inner side of the inner clamping member 11.

[0041] The setting of the inner decorative plate 15 improves the cleanliness of the inner surface of the foam board 14 and at the same time improves the durability.

[0042] The inner clamping member 11 and the outer clamping member 12 are metal plates, and a plurality of weight-reducing holes 123 are provided on the metal plates.

[0043] The inner clamping member 11, the outer clamping member 12 and the bolt connection member 13 form a frame structure, and the overall anti-deformation ability is better. At the same time, the metal plate can play a good limiting role for the wall. The setting of the weight-reducing holes 123 can reduce the weight of the metal plate, but will reduce the structural strength of the metal plate.

[0044] The specific usage method and function of this embodiment:

[0045] When the utility model is in use, a plurality of through holes 171 are drilled in the wall body 17 through a drill array, and then the inner clamping member 11 and the outer clamping member 12 are respectively placed on the inner surface and the outer surface of the wall body 17. A bidirectional screw 131 is inserted through the through hole 121 and its corresponding through hole 171, and a first nut 132 and a second nut 133 are respectively threadedly connected to both ends of the bidirectional screw 131. Then, a plurality of connecting ears 161 on the outer decorative plate 16 are respectively locked to their corresponding side ears 122 through bolts. Next, the foam board 14 is fixed by the inner clamping member 11 through foam glue, and the inner decorative plate 15 is fixedly connected to the inner surface of the foam board 14 through foam glue.
