The original wall 1 is a rectangular parallelepiped structure, the waterproof insulation board 11 is a rectangular parallelepiped structure, and a plurality of waterproof insulation boards 11 are provided and are installed on the side walls of the original wall 1. The decorative layer 12 is a rectangular parallelepiped structure, and a plurality of decorative layers 12 are provided and are respectively installed on the side walls of the plurality of waterproof insulation boards 11 away from the original wall 1.

[0029] When the staff needs to renovate the old wall, the staff needs to connect the waterproof insulation board 11 and the original wall 1 through the connection component 2. Then, the staff installs the decorative layer 12 on the side wall of the waterproof insulation board 11 away from the original wall 1 to complete the installation of the waterproof insulation board 11. In this process, the staff does not need to demolish the old wall, and the staff only needs to complete the installation of the waterproof insulation board 11 through the connection component 2, thereby reducing the installation cost and construction time.

[0030] The connection assembly 2 is installed between the original wall 1 and the waterproof insulation board 11, and is used to fix the waterproof insulation board 11 on the original wall 1. The connection assembly 2 includes a mounting plate 21, a connector 22, and a steel mesh 23. The mounting plate 21 is a rectangular plate-shaped structure, and the mounting plate 21 is fixed to the side wall of the original wall 1 by expansion screws. There are multiple connectors 22 and they are distributed in an array on the side wall of the mounting plate 21. One end of the connector 22 away from the mounting plate 21 is fixed to the waterproof insulation board 11, and the steel mesh 23 is installed on multiple connectors 22.

[0031] When the staff needs to install the waterproof insulation board 11, the staff needs to fix the installation board 21 and the original wall 1 to each other through expansion screws. Then, the staff installs the connecting piece 22 on the installation board 21, and further installs the wire mesh 23 on the connecting piece 22 to complete the installation of the waterproof insulation board 11, thereby reducing the installation cost and construction time.

[0032] The connecting member 22 includes a first connecting plate 221, a first sliding sleeve 222, a second connecting plate 223 and a second sliding sleeve 224. The first connecting plate 221 is a circular plate-shaped structure, and a plurality of first connecting plates 221 are provided. The plurality of first connecting plates 221 are fixed to the side wall of the mounting plate 21 by screws. The first sliding sleeve 222 is a cylindrical structure with one end open, and a plurality of first sliding sleeves 222 are provided and respectively fixedly arranged on the side wall of the plurality of first connecting plates 221 away from the mounting plate 21. The second connecting plate 223 is a circular plate-shaped structure, and a plurality of second connecting plates 223 are provided, and the plurality of second connecting plates 223 are fixedly arranged on the side wall of the waterproof and thermal insulation board 11 by screws. The second sliding sleeve 224 is a cylindrical structure with one end open, and a plurality of second sliding sleeves 224 are provided and respectively fixedly arranged on the side wall of the plurality of second connecting plates 223 away from the waterproof and thermal insulation board 11, and the second sliding sleeve 224 is slidably arranged in the first sliding sleeve 222.

[0033] A plurality of first connecting grooves 3 are formed on the side wall of the first sliding sleeve 222 , a plurality of second connecting grooves 31 are formed on the side wall of the second sliding sleeve 224 , the first connecting grooves 3 are directly opposite to the second connecting grooves 31 , and the wire mesh 23 is slidably disposed in the first connecting grooves 3 and the second connecting grooves 31 .

[0034] The staff needs to fix the first connecting plate 221 on the side wall of the mounting plate 21 away from the original wall 1 by screws. Then, the staff fixes the wire mesh 23 to the first connecting groove 3. At this time, the staff fixes the second connecting plate 223 to the side wall of the waterproof insulation board 11 away from the decorative layer 12 by screws. Then, the staff slides the second sliding sleeve 224 into the first sliding sleeve 222. During this process, the first connecting groove 3 is directly opposite to the second connecting groove 31, thereby reducing the probability of the wire mesh 23 blocking the second sliding sleeve 224, thereby improving the stability of the device.

[0035] The inner wall of the first sliding sleeve 222 is symmetrically provided with fixing grooves 4 , and two fixing blocks 41 are provided and symmetrically mounted on the side wall of the second sliding sleeve 224 , and the fixing grooves 4 and the fixing blocks 41 match each other.

[0036] When the staff needs to slide the second sliding sleeve 224 into the first sliding sleeve 222, the staff needs to make the first connecting groove 3 face the second connecting groove 31. Then, the staff presses the second sliding sleeve 224 to deform it. Then, the staff slides the second sliding sleeve 224 into the first sliding sleeve 222. During this process, when the fixing groove 4 faces the fixing block 41, the second sliding sleeve 224 returns to the state before deformation, and then the fixing block 41 is stuck in the fixing groove 4, thereby reducing the probability of the second sliding sleeve 224 and the second sliding sleeve 224 being separated from each other, thereby improving the stability of the device.

The filling layer 5 improves the overall wall of the wall. In addition, the filling layer 5 made of a mixture of cement and polyurethane improves the waterproof effect of the filling layer 5, thereby improving the waterproof effect of the wall. In this process, the steel wire mesh 23 reduces the probability of the filling layer 5 squeezing the waterproof insulation board 11 during the solidification process and causing the waterproof insulation board 11 to fall off, thereby improving the stability of the device.

[0038] In order to reduce the probability of water seepage inside the wall, a sealing strip 6 is installed on the side walls of the plurality of waterproof insulation boards 11 close to each other, and the sealing strip 6 abuts against the side wall of the decorative layer 12. The sealing strip 6 improves the sealing effect of the wall surface, thereby reducing the probability of water seepage inside the wall.

[0039] The use principle of a waterproof structure of an external insulation system for an exterior wall of a building in this embodiment is as follows: when the staff needs to renovate the old wall, the staff needs to fix the mounting plate 21 and the original wall 1 to each other by means of expansion screws. Subsequently, the staff needs to fix the first connecting plate 221 to the side wall of the mounting plate 21 away from the original wall 1 by means of screws. Subsequently, the staff fixes the wire mesh 23 to the side wall of the mounting plate 21 away from the original wall 1 by means of screws. Subsequently, the staff installs the wire mesh 23 into the first connecting groove 3. At this time, the staff fixes the second connecting plate 223 to the side wall of the waterproof insulation board 11 away from the decorative layer 12 by means of screws. Subsequently, the staff slides the second sliding sleeve 224 into the first sliding sleeve 222. At this time, the staff casts the filling layer 5 between the mounting plate 21 and the waterproof insulation board 11. At this time, the wire mesh 23 reduces the probability of the filling layer 5 squeezing the waterproof insulation board 11 during the solidification process and causing the waterproof insulation board 11 to fall off. During this process, the staff does not need to demolish the old wall. The staff only needs to complete the installation of the waterproof insulation board 11 through the connecting component 2, thereby reducing the installation cost and construction time.
