Background
Whether it is a tunnel, a bridge, a dam, a road, a building or a house which people live in daily life, the waterproof is a problem which cannot be ignored. The main structures of house buildings include foundations, walls, columns, buildings, floors, balconies, rainsheds, staircases, doors and windows, building roofs and the like, and among these structures, the building roofs, the walls of the main structure, the foundations, the floors, the doors and windows, the staircases, the balconies and the rainsheds are closely related to water proofing. The roof is arranged on the top of the building and mainly used for preventing rain (snow) water and ultraviolet rays from entering a room and insulating the room. The structure of the building mainly comprises a structural layer, a slope finding layer, a leveling layer, a steam barrier layer, a heat preservation layer, a waterproof layer, a protective layer, a ventilation and heat insulation layer or a veneer and the like. Because of the needs of buildings, the roof is often provided with a water outlet, an air outlet, a chimney, an access hole, a skylight and a tiger window, or the roof is provided with equipment or used as a swimming pool, a sports ground, an apron and the like, so the roof structure is relatively complex and has high waterproof requirements.
The roof of a building is generally provided with short walls, called parapet walls and grandson parapet walls, around the roof, which mainly have the main functions of maintaining safety, and applying waterproof pressed bricks at the bottom to prevent water seepage of a waterproof layer or overflow of rainwater on the roof. The parapet wall on the roof of the person is used for protecting the safety of the person and has a decorative effect on the building facade. The parapet wall without a roof has the function of fixing the asphalt felt besides the function of facade decoration. According to the national building code, the height of the parapet wall on the roof of the upper part of the house is generally not less than 1.1m and not more than 1.5m at most.
As is well known, the waterproof material has aging characteristics, and after a building is used for a certain period of time, the phenomenon of water leakage and water seepage caused by the aging of a waterproof layer is inevitable, so that the parapet cannot be used, especially the joint of the parapet and a flat roof, and therefore, the waterproof material is an important part for the waterproof repair of the existing building besides the waterproof design of the roof of a newly-built building. For the waterproof repairing of the parapet and the joint of the parapet and the flat roof, the prior art generally only focuses on the waterproofing and repairs or replaces the waterproof layer, but the influence of the bonding strength of the parapet and the flat roof on the service life of the waterproof layer is not considered, and the influence is exactly a key factor influencing the waterproof repairing effect.
