Detailed Description of the Specific Embodiments
[0018] The following will further elaborate on the specific embodiments of the present utility model in conjunction with the accompanying drawings of the embodiments, so that the technical solutions of the present utility model are easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0019] First Embodiment
[0020] This embodiment provides an in-situ reinforcement and repair structure for an external thermal insulation wall 5, as Figure 1 shown, including a special grouting reinforcement nail 1, an anchoring connector 2, a reinforced foamed ceramic board 3, and an adhesive 4. The adhesive 4 is applied on the reinforced foamed ceramic board 3 and the anchoring connector 2 is installed. The reinforced foamed ceramic board 3 is pasted onto the external thermal insulation wall 5 through the adhesive 4. The special grouting reinforcement nail 1 passes through the anchoring connector 2 and is inserted into the external thermal insulation wall 5. The special grouting reinforcement nail 1 has a grouting cavity, the side wall of the grouting cavity has a slurry outlet hole 11, the grouting cavity is filled with grouting glue 12, and the grouting glue 12 overflows into the external thermal insulation wall 5.
[0021] During construction, defect treatment and interface treatment are carried out on the external thermal insulation wall 5. The adhesive 4 is applied on the reinforced foamed ceramic board 3, and one end of the anchoring connector 2 is inserted into the reinforced foamed ceramic board 3. The reinforced foamed ceramic board 3 is pasted onto the external wall external thermal insulation wall 5. The special grouting reinforcement nail 1 is installed on the anchoring connector 2, and the grouting adhesive 12 is injected into the grouting cavity. The grouting adhesive 12 in the grouting cavity overflows from the slurry outlet hole 11 and enters the defective part of the external thermal insulation wall 5, enhancing the pulling force between the special grouting reinforcement nail 1 and the external thermal insulation wall 5. Wherein the external thermal insulation wall 5 is composed of a base wall and an external thermal insulation system, and the external thermal insulation system is composed of a thermal insulation layer, a protective layer, and fixing materials.
[0022] Some adjacent reinforced foamed ceramic boards 3 are provided with a relief joint, and a polyethylene foam rod 6 and a silicone sealant 7 are arranged in sequence from the inside to the outside of the relief joint. The relief joint provided with the polyethylene foam rod 6 and the silicone sealant 7 provides a relief space for the deformation of the reinforced foamed ceramic board 3, reducing the risk of rupture of the reinforced foamed ceramic board 3. In other alternative embodiments, the outer end of the special grouting reinforcement nail 1 has spines, and the spines are inserted into the polyethylene foam rod 6, so that the polyethylene foam rod 6 is more firmly pre-fixed, and then the silicone sealant 7 is filled on its outside, which is beneficial to ensuring the continuity of the process of filling the silicone sealant 7. Some adjacent reinforced foamed ceramic boards 3 do not have a relief joint.
[0023] As Figure 2 shown, the reinforced foamed ceramic board 3 is composed of a decorative layer 31, a foamed ceramic board 32, and a reinforcing layer. The decorative layer 31 is fixed on the outside of the foamed ceramic board, and the reinforcing layer is fixed on the inside of the foamed ceramic board. The reinforcing layer is composed of a reinforcing mesh 34 and a reinforcing adhesive 33. The reinforcing mesh 34 is an alkali-resistant fiberglass mesh cloth or a basalt fiber mesh cloth or an anti-cracking felt. The reinforcing adhesive 33 is selected as a glue with relatively superior strength, weather resistance, and waterproofness. The decorative layer 31 can be defined independently, and the decorative layer 31 is a stone-like finish or an aluminum plate finish.
[0024] Embodiment 2
[0025] The main difference between this embodiment and Embodiment 1 lies in the structure of the reinforced foamed ceramic board 3. As Figure 3 shown, in this embodiment, the reinforced foamed ceramic board 3 is composed of a decorative layer 31, a reinforcing layer, and a foamed ceramic board 32. The decorative layer 31 is fixed on the outside of the foamed ceramic board, and the reinforcing layer is fixed on the outside of the decorative layer 31. The reinforcing layer is only the reinforcing adhesive 33. The reinforcing adhesive 33 has a certain transparent section. Omitting the reinforcing mesh 34 can improve its aesthetics, and the decorative layer 31 can be seen through the reinforcing adhesive 33.
[0026] It should be understood that those of ordinary skill in the art can make improvements or modifications based on the above description, and all such improvements and modifications shall fall within the protection scope of the appended claims of this utility model.
