Carcass-free waterproof roll expansion force balancing device

Abstract

The invention discloses a carcass-free waterproof roll expansion force balancing device which comprises a carcass-free waterproof roll body, the carcass-free waterproof roll body comprises a protective layer, a first waterproof layer, a first elastic layer, a balancing layer, a second elastic layer, an isolation layer, a second waterproof layer and a slope making layer; the second waterproof layeris bonded to the top end of the slope making layer; the isolation layer is bonded to the top end of the second waterproof layer, the second elastic layer is bonded to the top end of the isolation layer, the balancing layer is bonded to the top end of the second elastic layer, and the first elastic layer is bonded to the top end of the balance layer. According to the carcass-free waterproof roll,the balancing layer is arranged, a tensile adhesive tape is arranged between the plastic strips of the balancing layer, so that the carcass-free waterproof roll has relatively high tensile resistance,and the expansion force balance of the carcass-free waterproof roll is ensured through the tensile force of the tensile adhesive tape when the waterproof roll is pasted; and protruding caused by unbalanced expansion force of the waterproof coiled material at the slope and the corner is effectively avoided, and the waterproof effect of the waterproof coiled material is prevented from being affected.

Description

technical field [0001] The invention relates to a carcass-free waterproof coiled material, in particular to a device for balancing expansion force of a carcass-free waterproof coiled material, and belongs to the technical field of waterproof coiled materials. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection with the building. It is the first barrier for waterproofing the whole project and plays a vital role in the whole project. Fibre-based membranes, glass cloth-based membranes and polyethylene-based membranes. [0003] In the process of laying the existing carcass-free waterproof membrane, the expansion force on the corner and bevel is unbalanced, which may easily cause the waterproof membrane at the key and bevel to bulge o...
