Technical Field
The invention belongs to the field of waterproof coiled materials, and particularly relates to a waterproof coiled material structure and a laying method thereof.
Background
Waterproofing is an important project in the construction of the roof of a building. The most common waterproofing method is to lay a waterproofing roll on top of the finished building. With the increasing demand of waterproof coiled materials, people have higher and higher performance requirements on the waterproof coiled materials, and the waterproof coiled materials with various performances such as ageing resistance, corrosion resistance, water resistance, hydrophobicity, degerming and the like are in the future. Among them, the most interesting is also the basic property of the waterproofing rolls, i.e. the waterproofing.
At present, waterproof rolls with excellent waterproof performance have ideal waterproof effect under experimental conditions, but in practical application, the experimental waterproof performance of the waterproof rolls cannot be fully exerted, and the main reason is that the structural design of connecting parts of the waterproof rolls, the laying technology and the like are insufficient.
Initially, people directly lay the waterproofing membrane by splicing two adjacent waterproofing membranes into a plane, and this laying technique does not have any special structural requirements for the joints of the waterproofing membranes. But the splicing area has a gap which can cause water seepage. Moreover, during the use process, the waterproof roll material in the splicing area is easy to curl, bulge and the like in the area due to various reasons such as stress, aging and the like, so that the service life of the waterproof roll material is greatly reduced.
Later, people tried to lay waterproofing membrane with two adjacent waterproofing membrane to carry out the mode of overlap joint, and the overlap joint can form the overlap region to avoided the gap, however, still can not effectively solve the coiled material at the overlap joint regional curling, the uplift scheduling problem that produces because of various reasons such as stress, ageing. And the thickness of the lap joint area is twice of that of other areas, and the whole waterproof layer is uneven and not attractive.
Afterwards, the researchers provide that the two opposite edge areas of the waterproof roll are provided with a thinning splicing part with a groove and a convex strip, then the splicing parts of the two adjacent waterproof rolls are overlapped, and the groove and the convex strip are clamped mutually, so that the whole waterproof layer is laid into a flat plane, and the mutual conflict, the bulge and the like between the waterproof rolls can be relieved. However, the structure and the laying method still cannot solve the gap generated by the overlapping method and the curling phenomenon initiated from the gap area caused by the stress.
Therefore, the invention aims to provide a waterproof roll structure and a laying method thereof, which can effectively solve the problems of water seepage and curling of a waterproof roll and a waterproof layer laid by the waterproof roll in a lap joint mode, improve the waterproof effect of the waterproof layer and prolong the service life of the waterproof layer.
