Description
Technical Field
This scheme belongs to roofing waterproof repair technical field, concretely relates to roofing seepage repair structure.
Background
Roof refers to the surface of the roof of a building and also to the portion between the ridge and the eaves. This portion occupies a larger area of the roof or the roof is a larger area portion of the roof. The construction method generally comprises a concrete cast-in-place floor, a cement mortar leveling layer, a heat insulation layer, a waterproof layer, a cement mortar protective layer, a drainage system, a parapet wall, lightning protection measures and the like, and the construction of tile surfaces (tile hanging strips) is also carried out during special engineering. When a roof leaks, the following repair techniques are generally used for repair, but these repair techniques have many drawbacks.
1) Repairing the roof leakage water by destructive excavation;
various machines and equipment need be used to the excavation in-process, and big power destructive demolishs, causes the irreversible destruction of structure easily, causes permanent loss after the structural destruction, is unfavorable for guaranteeing the service life of structure, even waterproof maintenance back again, can not ignore the damage that the structural destruction brought.
2) Repairing the roof leakage water by local cutting;
the method is characterized in that partial excavation is carried out on the water leakage part, although the price is reduced, the continuous hollowing of the protective layer is easily caused by the partial excavation, a gap is formed between the damaged waterproof layer and the newly repaired waterproof layer, the components of the new and old waterproof layers are inconsistent, the service life is reduced, and the method is not an effective waterproof method in general.
3) Directly paving the surface layer with the coiled material for repairing;
the waterproof layer is directly laid with the roof with water leakage, the structure cannot be damaged, but the method is equivalent to wearing a coat, the waterproof layer is directly exposed to the outdoor environment, and once the waterproof layer is damaged, the waterproof layer loses the waterproof effect.
4) Performing crack filling and waterproof treatment on the concrete surface crack by using asphalt factice;
the method only seals the large cracks seen on the surface, many small cracks cannot be repaired, only can play a temporary role, and the asphalt material is easy to age and greatly influenced by the environment and cannot meet the waterproof requirement.
Therefore, there is a need for improvement in the technique of repairing the leakage water on the roof.
Disclosure of Invention
In view of this, this scheme aims at overcoming at least one kind in the prior art not enough, provides a roofing seepage repair structure, solves current roofing repair or to the structure destructive damage, or the technical problem that life is lower.
In order to solve the technical problem, the following technical scheme is adopted:
the utility model provides a roofing seepage repair structure, includes former roofing structure, and former roofing structure includes structural layer, heat preservation, waterproof layer and the protective layer that sets up from bottom to top in proper order at least, still includes reverse slip casting repair structure, and reverse slip casting repair structure includes that the back fills in the first structure of filling in of locating the pressure release hole, and the pressure release hole is seted up on former roofing structure, is extended to the heat preservation by the structural layer lower surface.
