Waterproof connection method for coils

Abstract

The invention relates to a waterproof connection method for coils, which is characterized in that one end of one coil and one end of the other coil are connected together by vertical butt hooking or coiling, and accordingly waterproof leak-proof connection of the connecting ends of the coils is realized. By the method that the connecting ends of the coils are ingeniously connected by vertical butt hooking or coiling, a seam at the connection of the connecting ends which is prone to water penetration and seepage is wrapped inside formed joints, and water on the upper surfaces of the coils or on the lower surfaces of the coils cannot leak from the seam at the butt connection during use of the coils, and accordingly, the waterproof leak-proof connection of the connecting ends of the coils is realized. The waterproof connection method is simple in operation, timesaving and material-saving, and is widely applicable to connection of various coils, especially waterproofing work for base surfaces in the building industry.

Description

technical field [0001] The invention relates to the construction field, in particular to a method for waterproof connection of coiled materials. Background technique [0002] Waterproof membrane is mainly used in the base surface waterproofing treatment of various buildings. As we all know, in the existing construction field, when the coiled material is spread on the base surface of the building to form a complete waterproof layer, the problem of poor joint connection of the coiled material waterproof layer and the prevention and control of the joint connection of the coiled material waterproof layer are very critical. It is related to the sealing integrity of the waterproof layer of the coiled material. If the joints are not handled well or the connection is poor, water will seep in along the joint gaps and water seepage and water penetration will occur. At present, there are roughly two ways to solve the problem of joint connection between coils: one is to use the lap jo...

Problems solved by technology

At present, there are roughly two ways to solve the problem of joint connection between coils: one is to use the lap joint method, that is, the end or side of one coil is lapped on the end or side of another coil. On the edge, and apply adhesive on the overlapping joints to form a so-called adhesive film, but the connection effect of this overlapping and bonding is not good, and the joints are prone to water seepage and water penetration during use, so The waterproof function is not achieved, and because the length of the lap is generally about 150MM, the waste of the coil is large, resulting in high cost of use; the other is to use butt joint treatment, and then use 200-250mm wide on it The non-compound layer PVC coil covers the lap welding, which is cumbersome to operate, and there is also the phenomenon of water seeping through the welding seam and the butt seam
