Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-3, the utility model provides a composite waterproof roll, which comprises a roll cloth core 1, a first mesh cloth 3 and a second mesh cloth 4 adhered on the upper and lower surfaces of the roll cloth core 1;

the middle positions of the upper surface and the lower surface of the coiled material cloth core 1 are respectively provided with a groove 2, first grid cloth 3 is bonded in the groove 2 formed in the upper surface of the coiled material cloth core 1, and the first grid cloth 3 is bonded in the groove 2 formed in the lower surface of the coiled material cloth core 1;

the upper surface of 1 one end of coiled material cloth core and the lower surface of the 1 other end of coiled material cloth core have all been seted up and have been coincided groove 5, have protruding 7 in the groove 5 that coincide of 1 upper surface of coiled material cloth core, and the upper surface bonding of protruding 7 has sealed glue 8, has seted up strip groove 6 in the groove 5 that coincide of 1 lower surface of coiled material cloth core.

In the utility model, in the using process, the two sides of the waterproof cloth can be spliced, so that the bulge 7 is clamped into the strip-shaped groove 6, the anastomosis grooves 5 on the two coiled material cloth cores 1 are jointed, then the bulge 7 can be clamped into the strip-shaped groove 6, the jointing degree is better after each coiled material is jointed after being jointed, the seam is smoother, then the sealant 8 is adhered to the inner wall of the strip-shaped groove 6, and the anastomosis grooves 5 jointed on the two coiled materials are fixed together;
