Universal prestressed hollow slab for non-seepage flat roof

Abstract

The invention provides a seepage-free truncated roof floor system universal prestress hollow plate tile. The seepage-free truncated roof floor system universal prestress hollow plate tile is a structural construction self-waterproof system. The component production specification is in accordance with a dimensional coordination principle, and is universally applied to the field of roof waterproofing. A roof is subjected to primary rainwater drain prevention, a waterproof layer corresponds to a structural splicing slit, is subjected to self-adaptive fracture, and is in accordance with a natural law, such as thermal expansion and cold contraction and wet expansion and dry contraction, seeped water is subjected to waterproofing through a prestress hollow plate tile structure and secondary discharge prevention and seepage diversion, is then bore by a concave type waterproof water diversion ring groove, is guided into a water diversion pipe net of which the lower portion of a communication pipe is opened with a seeped water falling opening, is acted by a communication pipe principle effect, and is discharged out of a house, and in this way, the problems of roof fracture and seepage are solved. Formed is a waterproof technology effect of an integrally cooperative system which has primary discharge prevention of roof open water on a waterproof layer, conducts waterproofing through the prestress hollow plate tile structure, is shielded into the secondary discharge prevention and seepage diversion, combines the roof concave type waterproof water diversion ring groove pipe net, and guides the seeped water to be drained out.

Description

technical field [0001] The technology belongs to the field of building roof waterproofing. Background technique [0002] The structural layer of the flat roof floor is generally a reinforced concrete roof, that is, a cast-in-place reinforced concrete roof and a prefabricated reinforced concrete slab roof. [0003] The cast-in-place reinforced concrete roof obeys the law that cracks occur repeatedly from the middle, and there is also a random crack distribution or a complex crack distribution that produces both. [0004] In multi-storey residential, small high-rise and high-rise buildings, construction cracks of 0.1mm-0.2mm usually appear in the cast-in-place reinforced concrete roof structure layer, and even penetrating cracks larger than 0.2mm may appear. mm is reduced to 0.2mm, about 30% of the reinforcement needs to be increased, and the economy of waterproof technology and the effect of controlling cracks are not good.

AI Technical Summary

Problems solved by technology

[0006] At present, reinforced concrete roofs are covered with fully enclosed waterproof material technology to solve the problem of roof structure cracking and seepage. The shrinkage value is also different, so that the materials are rigid and flexible with each other, compatible and matched, the construction operation is not easy, the material is aging, and the leakage problems caused by inconsistency, etc.
