[0002] With the continuous development of the construction industry, the functional requirements of buildings are becoming higher and higher, especially the waterproof performance of exterior walls. In building construction, waterproofing of exterior walls is very important. It can effectively prevent moisture penetration and thus protect the building structure from damage. Usually, various water-resistant and weather-resistant materials are used to construct a waterproof isolation layer to prevent moisture from penetrating into the interior of the building structure.

[0003] The current waterproof exterior walls of buildings are mainly composed of a base wall, a concrete mortar leveling layer installed on the outside of the base wall, an insulation layer attached to the outer wall of the concrete mortar leveling layer, an ordinary waterproof coating installed on the outside of the insulation layer, and a finishing layer installed on the outside of the waterproof layer. Although the exterior walls of buildings with this structure have certain waterproof performance when in use, during actual use of the waterproof walls of the above structure, on the one hand, the waterproof coating thereon is easily affected by the external environment and cracks and falls off, thereby causing the waterproof effect of the waterproof wall of the building to deteriorate, making the maintenance cost of the waterproof wall of the building high. On the other hand, when installing the insulation layer on the waterproof wall of the above structure, the concrete mortar leveling layer is first applied on the base wall, and then the insulation is attached to the base wall for installation. Under this installation method, the concrete mortar leveling layer applied first dries too quickly, resulting in uneven adhesion of the insulation layer at different locations after installation, resulting in loosening and falling off, which shortens the service life of the waterproof wall of the building.

It solves the problem that the waterproof coating on the building waterproof wall in the prior art is easily affected by the external environment and cracks and falls off during actual use, which leads to the deterioration of the waterproof effect of the building waterproof wall and the high maintenance cost of the building waterproof wall. At the same time, when installing the insulation layer 3 on the existing building waterproof wall, a concrete mortar leveling layer 2 is first applied on the base wall 1, and then the insulation is attached to the base wall 1 for installation.

At this time, the thermal insulation layer 3 is tightly fitted to the outer wall of the base wall 1, and a space for installing the concrete mortar leveling layer 2 is formed in the sealing frame 601. At this time, it is only necessary to pour concrete mortar into the space. After the concrete mortar is densely formed, the construction of the concrete mortar leveling layer 2 can be realized. Under this installation method, the fit between the thermal insulation layer 3 and the base wall 1 is more firm, and there is no The insulation layer 3 will fall off, thereby extending the service life of the building's waterproof wall. A self-repairing nano waterproof coating 4 is used as the waterproof coating of the building's exterior wall, and a fitting groove 7 and a convex strip 8 are arranged between the repairing nano coating and the insulation layer 3. While ensuring the reliable bonding and fixation of the self-repairing nano coating, the weather resistance and durability of the building's waterproof exterior wall are significantly improved. It can also realize automatic repair of the waterproof layer on the building's exterior wall when it is accidentally cracked, so that the waterproof effect of the building's waterproof exterior wall is better.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, the insulation layer 3 includes a centrally arranged reinforcement frame 302 , an inner insulation board 303 installed on the inner side of the reinforcement frame 302 , and an outer insulation board 301 installed on the outer side of the reinforcement frame 302 .

[0034] As an embodiment, the inner insulation board 303, the outer insulation board 301 and the reinforcing frame 302 together form the main structure of the insulation layer 3, ensuring that the insulation layer 3 has sufficient strength while ensuring the insulation performance of the insulation layer 3.

[0035] like Figure 3As shown, in this embodiment, the reinforcement frame 302 is mainly composed of a square frame, parallel cross bars installed in the frame, and protrusions installed on both sides of the frame and the cross bars.

[0036] As an implementation method, the reinforcement frame 302 is formed by welding stainless steel bars, which can effectively ensure the structural strength of the reinforcement frame 302 itself.

[0040] As an implementation method, the outer insulation board 301 and the inner insulation board 303 can effectively fit the gaps on the strong frame after installation, ensuring the density of the insulation layer 3's own structure, thereby ensuring the insulation performance of the insulation layer 3.

[0041] like Figure 1 、 Figure 4 and Figure 5 As shown, in this embodiment, the fitting groove 7 is formed on the outer insulation board 301, and the fitting groove 7 is an arc-shaped long strip structure, and the size of the protrusion 8 matches the size of the fitting groove 7.

The mechanism of repairing cracks in the self-repairing nano coating is that when the self-repairing nano coating cracks, the self-repairing microcapsules inside it will fill the crack position. After the self-repairing repair is exposed to moisture, it will expand and rupture, so that the substance in the self-repairing microcapsules will fill the crack, thereby realizing the self-repairing function of the building exterior wall, making the building exterior wall more waterproof.

[0043] like Figure 1-Figure 2 As shown, in this embodiment, the T-shaped slot 603 is formed on the base wall 1, and the T-shaped slot 603 passes through the base wall 1, and the T-shaped insert 602 matches the size of the T-shaped slot 603.

[0044] As an implementation mode, the thermal insulation layer 3 can be reliably hung on the base wall 1 with the cooperation of the T-shaped plug block 602 and the T-shaped slot 603 , thereby realizing the pre-installation of the thermal insulation layer 3 .

[0046] As an embodiment, when the height is the same, the insulation layer 3 can be reliably sealed and fitted with the base wall 1 after installation to avoid non-overlapping parts. At the same time, the insulation layer 3 can be installed synchronously under the action of the T-shaped plug 602.

[0047] The specific implementation process of this embodiment is as follows: when assembling the waterproof exterior wall of the building, the T-shaped plug block 602 is first inserted into the T-shaped slot 603 to realize the pre-installation of the thermal insulation layer 3 on the base wall 1. At this time, the thermal insulation layer 3 is tightly fitted with the outer wall of the base wall 1, and a space for the installation of the concrete mortar leveling layer 2 is formed in the sealing frame 601. At this time, it is only necessary to pour concrete mortar into the space. After the concrete mortar is densely formed, the construction of the concrete mortar leveling layer 2 can be realized. Then, it is only necessary to apply the self-repairing waterproof coating and the thermal insulation layer 3 in sequence to complete the construction of the waterproof wall of the building. Under the installation method, the adhesion between the insulation layer 3 and the base wall 1 is made firmer, and the insulation layer 3 will not fall off, thereby extending the service life of the building waterproof wall. At the same time, a self-repairing nano waterproof coating 4 is used as the waterproof coating of the building exterior wall, and a fitting groove 7 and a convex strip 8 are arranged between the repair nano coating and the insulation layer 3. While ensuring the reliable adhesion and fixation of the self-repairing nano coating, the weather resistance and durability of the building waterproof exterior wall are significantly improved. It can also realize automatic repair of the waterproof layer on the building exterior wall when it is accidentally cracked, so that the waterproof effect of the building waterproof exterior wall is better.
