Precast concrete waterproof structure

Abstract

The invention discloses a precast concrete waterproof structure, and belongs to the field of assembled buildings. The precast concrete waterproof structure comprises a water stop sill for isolating aneasy damping area from a damp preventing area; the water stop sill comprises a waterproof main body, and a projection part arranged at the top of the waterproof main body; the bottom of the projection part covers part of the area of the waterproof main body; the lower part of the waterproof main body is embedded in a reserved groove of a floor top surface; and the projection part and the part, not covered by the projection part, of the waterproof main body are connected with a wall, and form step type joints with the wall. Compared with the prior art, a concrete waterproof structure is prefabricated in a factory, and is directly connected with a floor reserved groove during construction; the manufacturing precision of the waterproof structure is high; the problem of need of supporting templates in scene casting is prevented; and the construction difficulty is lower.

Description

Technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a precast concrete waterproof structure. Background technique [0002] Concrete sills (used for waterproofing) generally have more water-retaining functions; such as the lower part of the door of the room, around the equipment room and other parts; concrete sills are installed in the kitchen, toilet, bathroom, etc.; the existing concrete The cast-in-place concrete sills are all cast-in-place; the cast-in-situ concrete sills have the following problems; the first is that the dimensional accuracy of the reverse sills is not enough to reach the millimeter level, resulting in poor waterproof performance; the second is that the cast-in-situ concrete is prone to vibration In the case of non-compactness, there are honeycomb pitted surfaces and holes; the third is that the construction is more difficult when constructing on the finished surface of the floor; at present, the production o...

AI Technical Summary

Problems solved by technology

[0002] Concrete sills (for waterproofing) are generally used to retain more water; such as the lower part of the door of the room, the surrounding equipment of the machine room, etc.; there are concrete sills in the kitchen, toilet, bathroom, etc.; the existing concrete The cast-in-place concrete sills have the following problems: first, the dimensional accuracy of the cast-in-place concrete sills is not enough to reach the millimeter level, resulting in poor waterproof performance; second, the cast-in-place concrete is prone to vibration If it is not dense, there will be honeycomb pockmarks and holes; the third is that the construction on the finished surface of the floor is more difficult; at present, the production of waterproof sills has become an unsolved problem in the industry and needs to be solved urgently
