Anti-leakage prefabricated component

Abstract

The invention provides an anti-leakage prefabricated component which comprises a prefabricated component base layer and a drainage body. The prefabricated component base layer comprises a groove cement plate and a filling layer, the filling layer is disposed between the groove cement plate and the drainage body, a groove of the groove cement plate is of a U type, the left side and the right side of the groove cement plate are provided with connection grooves arranged oppositely, and a drainage hole is formed in the bottom of the drainage body. The anti-leakage prefabricated component has the advantages that cracking does not happen when the component is used, the service life is long and the component does not need to be maintained frequently.

Problems solved by technology

[0002] At present, the sloped roof of prefabricated components often adopts a light structure, and cracks often appear after a period of use, causing water leakage; or leakage occurs due to the micropores and capillary pores formed during the hydration and hardening process of the roof cement

After the roof waterproof layer fails and leaks, it needs to be repaired and repaired. However, because light prefabricated concrete components should not be drilled in large quantities, and this type of early-built houses often cannot meet the requirements of energy saving and emission reduction, so this type of roof cannot increase the load, and it is difficult to carry out thorough repairs. transform

There is also a simple leak-proof and leak-repairing method that is used to scald the roof surface with asphalt. The disadvantage of this method is that the service life is short, generally 3-5 years

At the same time, prefabricated reinforced concrete porous slabs are generally used for the roof of housing construction. Expanded perlite is used as an insulation layer on the top of the slab, and then waterproof rolls are laid with asphalt to make three-oil and two-stick waterproof materials. Soft materials are also used. For example, plastic ointment, modified asphalt and some other plugging agents are used as waterproof materials. This kind of structure has low cost, simple construction, and low labor intensity. Roof leaks are inevitable when cracks develop

In addition, there is another kind of reinforced concrete poured on site as the roof structure. This structure has the advantage of strong anti-leakage ability, but it has the weight of the entire roof, cumbersome construction technology, long cycle, high labor intensity, and high cost. High, unsatisfactory thermal insulation performance
