Description

Water seepage prevention structure of building roof

Technical Field

In order to prevent the roof connection structure from being corroded and cracked under the erosion of ponding, the prior art personnel adopt modes such as structural waterproofing at corner joints to drain water and prevent water. However, in some extreme environments, such as exposure environments, the rigid structure is waterproof and can exert a force on corners, so that the roof structure becomes unstable, the wall is easy to crack, the normal waterproof function of the roof cannot be ensured, and the maintenance cost is greatly increased.

The flexible waterproof method can be used for anti-seepage treatment of the corner of the building roof, and has the main advantages of low cost, good durability, few construction procedures and convenient maintenance. However, the puncture resistance and the ageing resistance of the waterproof layer are inferior to those of a rigid material, and when the wall body is once deformed, the flexible waterproof layer can also be directly cracked, so that rainwater is easy to leak from the waterproof layer.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, the present utility model provides a water seepage preventing structure of a building roof, which is arranged at the junction of the upper wall surface of the roof and the plane of the roof, namely, at the corner. The roof upper beam body is a roof beam or parapet and other structures. The water seepage prevention structure comprises a flexible waterproof layer 1 arranged at a corner and a structural waterproof layer 2.

The flexible waterproof layer 1 is wrapped and arranged on the corner of the building roof and extends to the wall surface and the roof plane. The flexible waterproof layer 1 is made of flexible waterproof materials including asphalt felt, glass cloth, asphalt of various cementing materials and the like.

The structural waterproof layer 2 is installed above the flexible waterproof layer 1, the structural waterproof layer 2 comprises supporting plates 201 which are mutually meshed and installed on the flexible waterproof layer 1, one ends of the supporting plates 201 are embedded and installed together through a first structure 202, and the other ends of the supporting plates 201 penetrate through the flexible waterproof layer 1 through a second structure 203 and are embedded and installed in a wall body at a corner.

Wherein the flexible waterproof layer 1 is used for performing primary waterproof on corners, and the supporting plate 201 is used for performing secondary waterproof on corners and performing rigid support on walls forming the corners.

In this embodiment, the waterproof layer 2 is rigid, and the waterproof purpose of the building is achieved by taking the compactness of the structural member as the waterproof layer, meanwhile, the flexible waterproof layer 1 is not easy to adhere, so that the waterproof layer 1 is directly installed on the wall body by penetrating through the flexible waterproof layer 1 in a structural installation mode, not only can realize the waterproof of the corner, but also can prevent rainwater from penetrating. The waterproof layer 2 can support the wall body, prevent cracks caused by later deformation of the wall body, can protect the flexible waterproof layer 1, prevent the flexible waterproof layer from oxidative cracking under the irradiation of sunlight, and improve the leakage resistance.

The general rigid waterproof material is prepared by mixing cement and sand stone as raw materials in proportion, so that the compactness between raw material interfaces is improved. In the utility model, adopt the mode of backup pad 201 interlock each other to shelter from and cover the flexible waterproof material of corner department, can improve the speed of drainage on the one hand, prevent that the wet thing from piling up, be convenient for the rainwash and walk the heap. Simultaneously be convenient for overlap joint, owing to in the utility model, structure waterproof layer 2 has the effect of support simultaneously, so structure waterproof layer 2 when in actual use, can overlap joint the corner that appears infiltration phenomenon or wall body fracture phenomenon has been started, remedy infiltration and fracture.

The rigid waterproof material and shape can be various, but in extreme environments such as sunlight exposure or extremely cold weather, the waterproof structure is easy to expand with heat and contract with cold due to the rigid waterproof material, and deform in the process of expanding with heat and contracting with cold, so that the corner connected with the waterproof structure and the flexible waterproof layer 1 are subjected to tensile force or pushing force, and the wall and the flexible waterproof layer 1 are easy to crack.

In order to solve the problem that the waterproof layer 2 is easy to deform, the supporting plate 201 is of a sheet-shaped structure, the middle position of the sheet-shaped structure is bent to be an obtuse angle, the bending position of the supporting plate 201 is provided with a mounting groove 3 for placing the first structure 202, and the first structure 202 is embedded in the mounting groove 3; the two support plates 201 are connected by a first structure 202.
