Waterproof technology of prefabricated external wall panel

Abstract

Provided is a waterproof technology of prefabricated external wall panels. The waterproof technology comprises an upper window frame, a first prefabricated external wall panel, a connecting layer, a second prefabricated external wall panel, a lower window frame, polyethylene tubes, a weather-proof adhesive layer, a foamed PVC rod, and a high-strength fine concrete layer. The outer side of the connecting plane of the first prefabricated external wall panel and the upper window frame is provided with a slope. The outer side of the connecting plane of the second prefabricated external wall panel and the lower window frame is provided with a slope, and the inner side is provided with the polyethylene tube. The connecting layer is in a raised shape, and the left side is provided with the weather-proof adhesive layer and the foamed PVC rod, the top end is filled with the foamed PVC rod, and the right side is provided with the high-strength fine concrete layer. Through arranging the slope on the outer side of the connecting plane of the first prefabricated external wall panel and the upper window frame, a dripping function is added. The outer side of the connecting plane of the second prefabricated external wall panel and the lower window frame is provided with the slope, and the inner side is provided with the polyethylene tube, so as to prevent water from permeating. The connecting layer is made in the raised shape, multiple waterproofing is formed, and a problem of wall leakage caused by non-waterproofness of the wall panel is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a waterproofing technology for prefabricated outer wall panels; it is mainly used for prefabricated houses. Background technique [0002] The exterior wall of the building is eroded by rain all the year round. It should meet higher requirements in terms of safety and durability, especially in terms of waterproofing. If the exterior wall is not waterproof, the erosion of rainwater all the year round will cause the wall to absorb a lot of water. In a water environment, and often exposed to sunlight, the service life of building materials and decorative materials will be greatly reduced; When evaporation occurs in the wall, the inner wall will become damp, moldy, peel off, etc., which is extremely harmful; therefore, the waterproof treatment between the prefabricated outer wall panels and the prefabricated outer wall panels and window frames is a must for residents' l...

[0002] The exterior wall of the building is eroded by rain all the year round. It should meet higher requirements in terms of safety and durability, especially in terms of waterproofing. If the exterior wall is not waterproof, the erosion of rainwater all the year round will cause the wall to absorb a lot of water. In a water environment, and often exposed to sunlight, the service life of building materials and decorative materials will be greatly reduced; When evaporation occurs in the wall, the inner wall will become damp, moldy, peel off, etc., which is extremely harmful; therefore, the waterproof treatment between the prefabricated outer wall panels and the prefabricated outer wall panels and window frames is a must for residents' lives. Important guarantee; therefore, the present invention provides a prefabricated exterior wall panel waterproofing technology, by providing a slope on the outside of the connection plane between the first prefabricated exterior wall panel and the upper window frame, and adding a dripping function, between the second prefabricated exterior wall panel and the lower window There is a slope on the outside of the connection plane of the frame, and a polyethylene pipe on the inside to prevent water intrusion. The connection layer is made into a convex shape to form multiple waterproofing, which can effectively reduce the wall leakage and cracks caused by the non-waterproof wallboard. , which greatly guarantees the use and appearance of the building, the appearance of the city, and the safety of residents
