Description

Waterproof roll easy to splice

Technical Field

The utility model relates to a construction technical field especially relates to a waterproofing membrane of easily splicing.

Background

The waterproof coiled material is mainly used for building walls, roofs, tunnels, highways, refuse landfills and the like, can be curled into a roll-shaped flexible building material product for resisting external rainwater and underground water leakage, is used as a leakage-free connection between an engineering foundation and a building, is a waterproof first barrier of the whole engineering, and plays a vital role in the whole engineering.

Current waterproofing membrane, during the use, long limit direction needs the overlap joint, makes upper waterproofing membrane overlap joint on lower floor waterproofing membrane, and the overlap joint is accomplished the back, for guaranteeing water-proof effects, needs to use the waterproof glue to further handle in the overlap joint department. Because the lapping part of the waterproof coiled material is longer, the waterproof glue is time-consuming and labor-consuming for further treatment.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the waterproof roll easy to splice of the present invention comprises an upper layer roll 1 and a lower layer roll 2; the lower surface of the upper layer coiled material 1 and the upper surface of the lower layer coiled material 2 are both provided with bonding layers 4, so that the upper layer coiled material 1 and the lower layer coiled material 2 are bonded; the long edge of upper coiled material 1 all sets up isolation layer 3 with the long edge of lower floor's coiled material 2, makes upper coiled material 1 with lower floor's coiled material 2 is in the separation of long edge. During the use, will treat lapped waterproofing membrane's upper coiled material 1 and lower floor's 2 edges of coiled material isolation layer 3 and tear, make upper coiled material 1 and lower floor's coiled material 2 bond, then fill in lapped waterproofing membrane with it with holistic form, between lapped waterproofing membrane's upper coiled material 1 and lower floor's coiled material 2 promptly, tear lapped coiled material's isolation layer, make lapped coiled material's tie coat 3 glue and hold and treat lapped waterproofing membrane. And finishing the lapping work. The effect is shown in figure 2. Since two adjacent waterproofing rolls are overlapped in a half-wrapped manner, the waterproofing effect is sufficiently ensured. Simultaneously, need not to further use the waterproof glue at waterproofing membrane's long limit department and handle, only need in the handing-over department coating waterproof glue of long limit and minor face can, easy operation, labour saving and time saving.

The middle and upper coiled material 1 of the utility model comprises an upper tyre base layer 1-1, a first modified asphalt layer 1-2, a non-woven fabric layer 1-3, an isolation layer 1-4 and a protection layer 1-5 which are arranged from bottom to top in sequence; the lower coiled material comprises a lower tire base layer 2-1, a second modified asphalt layer 2-2, a PVC alloy layer 2-3, a glass fiber cloth layer 2-4 and a polyvinyl acetate layer 2-5 which are sequentially arranged from top to bottom. See fig. 3. The utility model is provided with two modified asphalt layers, which increases the self-healing capacity of the waterproof coiled material; the PVC alloy layer is arranged, so that the flame retardance and the puncture resistance are enhanced.

Preferably, the upper base course layer 1-1 and the lower base course layer 2-1 are both plant bast fiber layers. The plant bast fiber layer increases the tensile strength of the waterproof roll.

Preferably, the adhesive layer 4 is a bisphenol a epoxy resin adhesive layer 3, which has high adhesiveness.

Preferably, the isolation layer 3 is a release film, and the release film is a PP or PE film.
