Background

The existing roof waterproof is basically realized by adopting a coiled material, so that the water seepage in the roof is avoided.

Referring to fig. 1, the utility model discloses an application roofing external and internal corner seepage maintenance structure 100, external and internal corner seepage position includes external and internal corner crack zone and with the external and internal corner basal plane district that external and internal corner crack zone is connected at least, external and internal corner seepage maintenance structure specifically includes: an acrylate slurry layer 10 laid in the internal and external corner crack region; a capillary concrete pore sealing permeable layer 30 laid on the base surface area of the male and female corners; the epoxy adhesive layer 40 is laid on the acrylate slurry layer 10 and the capillary concrete pore sealing and permeating layer 30; a polymer composite alkali-resistant fiber cloth layer 50 laid on the epoxy adhesive layer 40; and a waterproof coating layer 60 laid on the high-molecular composite alkali-resistant fiber cloth.

Specifically, the internal and external corner leakage maintenance structure that this application provided is mainly applied to the place of internal and external corner position department infiltration. The internal and external corner crack area is a waterproof failure position at the internal and external corners of the original basal plane, and the internal and external corner basal plane area specifically refers to a vertical plane including the internal and external corners and a bottom surface including the internal and external corners, which are connected with the internal and external corner crack area.

When the anti-leakage treatment is carried out on the positions of the internal and external corners, the crack areas of the internal and external corners and the base surface areas of the internal and external corners, namely the surface of the concrete 90, are ensured to be free from floating slag, dust and oil stains, and the surface is kept clean and free from oil stains.

And the acrylate slurry layer 10 is laid in the internal and external corner crack area, and the acrylate slurry layer 10 transmits acrylate slurry to the internal and external corner crack area through a channel opening 11 arranged in the internal and external corner base surface area to form the acrylate slurry layer 10. The interval distance between the adjacent channel openings 11 in the plurality of channel openings 11 is 10cm to 20 cm. The channel port 11 is a base surface area of a yin-yang angle, which is 5cm away from the innermost side of the yin-yang angle, and inclined holes are formed in the base surface area, and an intersection point exists between the inclined holes of the channel port 11 and the crack. When the slurry is blown out from the passage opening 11, the slurry is continuously injected for 5-10 s, and then the slurry injection is stopped. It should also be noted that the acrylate grout layer 10 is injected with acrylate grout through several passage ports 11 in the order from bottom to top, from left to right. The grouting sequence may also be from bottom to top, from right to left.

And a leakage blocking layer 20 is paved on the base surface area of the male and female corners and is used for blocking a plurality of channel openings 11 after the acrylate slurry is transmitted.

Specifically, when the plugging layer 20 plugs the plurality of passage openings 11 of the acrylate slurry layer 10, it is necessary to confirm that no water is leaked at the position of the internal and external corners after the acrylate slurry layer 10 is laid, and then the plugging material may be used to plug and level the holes left by the grouting nozzles.
