[0034] The present utility model provides a waterproof and seepage-proof structure for the exterior wall of a building. A waterproof mixed layer is mainly formed by pouring, and water is guided outward through the intervals and inclined waterproof guiding members in the waterproof mixed layer, reducing the possibility of water spreading to the brick-concrete layer.

[0035] The following will detail a waterproof and seepage-proof structure for the exterior wall of a building according to the present application through the following embodiments.

[0036] In this embodiment, as Figures 1 to 4 shown, the waterproof and seepage-proof structure of the exterior wall of the building includes, from outside to inside in sequence: a sandblasting layer 1, a waterproof mixed layer 2, a brick-concrete layer 3, an inner cement layer 4, and an inner finish layer 5;

[0037] The waterproof mixed layer 2 includes an outer cement layer 201 and a number of waterproof guiding members 202 provided in the outer cement layer 201. The outer cement layer 201 wraps around the periphery of each waterproof guiding member 202, and each waterproof guiding member 202 is spaced apart. Each waterproof guiding member 202 is inclined, and the height of the end of the waterproof guiding member 202 close to the sandblasting layer 1 is lower than the height of the end close to the brick-concrete layer 3.

[0038] In this technical solution, the sandblasting layer 1 is formed by performing a sandblasting process on the outer side of the waterproof mixing layer 2. The sandblasting layer 1 is arranged on the outermost side to enhance the aesthetics, surface area, and heat insulation effect of the water-proofing structure, etc. The waterproof mixing layer 2 is cast on the outer side of the brick-concrete layer 3 through a mold. First, the waterproof guiding members 202 are evenly spaced up and down on the outer side of the brick-concrete layer 3 in advance, and then cement or a mixture of cement and sand and gravel is cast under the limitation of the mold to form an outer cement layer 201 that wraps around the periphery of each waterproof guiding member 202 up, down, left, and right. After solidification, the mold is removed. The waterproof guiding members 202 are arranged in the form of being lower on the outer side and higher on the inner side in the inner cement layer 4. The waterproof guiding members 202 are made of steel, aluminum, or polyurethane materials. The waterproof guiding members 202 are integrally arranged in a plate shape, and each waterproof guiding member 202 is horizontally arranged front and back. The brick-concrete layer 3 includes multiple brick layers 301, and each layer is provided with multiple bricks. The adjacent bricks are bonded with cement, and the bricks of the adjacent brick layers 301 are arranged in a staggered manner front and back. The inner cement layer 4 is coated on the inner side surface of the brick-concrete layer 3, and the inner smooth layer 5 is coated on the inner side surface of the inner cement layer 4. The inner smooth layer 5 is usually made of lime material.

[0039] During use, when the rainwater from the outside hits the sandblasting layer 1, due to the relatively large gaps in the sandblasting layer 1, there will be a situation where some moisture moves inward or accumulates. The moisture moving inward contacts the waterproof guiding member 202 after passing through the outer side part of the outer cement layer 201 of the water-reverse mixing layer. Then, under the action of the inclined waterproof guiding member 202, the inward movement of the moisture is hindered from further spreading inward, prompting the moisture moving inward to flow downward through the gaps between the sandblasting layer 1 or the sandblasting layer 1 and the waterproof mixing layer 2, thereby achieving the waterproof effect. And because the waterproof guiding members 202 are spaced from each other, a certain degree of water vapor exchange can be carried out between the inside and outside of the wall, and the connection effect between the inside and outside of the wall can be enhanced, and the cost problem caused by the use of the waterproof guiding members 202 can be reduced.

[0040] In this embodiment, the waterproof guiding member 202 includes:

[0041] An inclined section 203, the inclined section 203 is inclined, and the height of the end of the inclined section 203 close to the sandblasting layer 1 is lower than the height of the end close to the brick-concrete layer 3;

[0042] A vertical section 204, the vertical section 204 is fixedly arranged on the side of the inclined section 203 close to the brick-concrete layer 3, and the vertical section 204 is vertically arranged.

[0043] In this technical solution, the waterproof guiding members 202 on the left side are inclined sections 203, and the waterproof guiding members 202 on the right side are vertical sections 204. Such a setting can prevent moisture from moving inward over the upper side of the inclined section 203.

[0044] In this embodiment, the waterproof guiding member 202 is provided with a plurality of through holes for the outer cement layer 201 to pass through.

[0045] In this technical solution, a plurality of through holes are provided on both the inclined section 203 and the vertical section 204. The through holes on the inclined section 203 are vertically penetrated, and the through holes on the inclined section 203 are penetrated in the left - right direction. Such a setting enables the outer cement layer 201 to pass through the through holes during pouring for its own integral forming, improving the connection effect between the outer cement layer 201 and the inclined guiding member.

[0046] In some technical solutions, the through holes on the vertical section 204 are inclined with respect to the horizontal plane. In other words, there is a height difference in the vertical direction for the through holes on the vertical section 204.

[0047] In this embodiment, the waterproof guiding member 202 is provided with a guiding groove.

[0048] In this technical solution, the guiding groove is arranged on the upper surface of the inclined section 203. The arrangement of the guiding groove improves the ability of the inclined section 203 to converge moisture and reduces the ability of water vapor to move back and forth in the waterproof mixing layer 2.

[0049] In this embodiment, the waterproof guiding member 202 is provided with a fixing hole. The fixing hole communicates with the side surface of the waterproof guiding member 202 close to the sand - blasting layer 1, and a guiding member 205 is provided at the fixing hole.

[0050] In this technical solution, a plurality of fixing holes are arranged on the left - hand side surface of the inclined section 203. The guiding member 205 is a vertical rod - shaped member, and an expansion part is provided at the top end of the guiding member 205, so that the guiding member 205 can be inserted and fixed in the fixing hole, and after insertion, the outer side surface of the guiding member 205 is connected to the left - hand side surface of the inclined section 203, prompting the water flowing through on the waterproof guiding member 202 to move downward under the guiding action of the guiding member 205.

[0051] In this embodiment, the waterproof guiding members 202 are uniformly arranged in the up - down direction, and the bottom end of the guiding member 205 on the upper - side waterproof guiding member 202 is not higher than the top end of the adjacent lower - side waterproof guiding member 202.

[0052] In this technical solution, the bottom end of the guiding member 205 on the upper - side waterproof guiding member 202 is lower than the top surface of the vertical section 204 of the adjacent lower - side waterproof guiding member 202, reducing the possibility of the water flowing through on the upper - side guiding member 205 moving between the adjacent waterproof guiding members 202.

[0053] In this embodiment, a plurality of guiding grooves are provided on the side surface of the sand - blasting layer 1 away from the waterproof mixing layer 2.

[0054] In this technical solution, the guiding grooves include a plurality of inclined - arranged and a plurality of vertically - arranged ones, and the inclined - arranged guiding grooves are communicated with the vertically - arranged guiding grooves.

[0055] The embodiments of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
