Waterproofing membrane for construction

Abstract

The utility model relates to the technical field of construction materials, and the utility model provides a waterproofing membrane for construction, which comprises a membrane body, and the membrane body is sequentially stacked from top to bottom with an outer layer, an aging-resistant asphalt layer, a first tire base reinforcing layer, a first asphalt bonding layer, a second tire base reinforcing layer, a second asphalt bonding layer and a separation bottom layer; a female port structure is formed on the other side of the membrane body, and a male port structure is arranged on one side of the membrane body; the male port structure can be inserted into the female port structure to connect adjacent membrane bodies; the female port structure is arranged between the first tire base reinforcing layer and the first asphalt bonding layer or on the first asphalt bonding layer; a detachable female port separation film is arranged on the first asphalt bonding layer; and the female port separation film separates the two branches of the female port structure. The double tire base reinforcing layers improve the strength of the membrane, the insertion structure guarantees the sealing property of the connection, the female port separation film prevents adhesion, the problems of insufficient strength and unreliable connection of the traditional single tire base membrane are solved, and the reliability and durability of waterproof engineering are improved.
