Problems solved by technology
[0002] In the past, the leak-proof treatment of the roof was usually to increase the waterproof material layer or improve the compactness of the roof layer or to change the material of the roof layer. The leak-proof effect of this method was not very satisfactory, because the roof was exposed to wind and sun for a long time, and it was easy to Due to thermal expansion and cold contraction, local cracks are generated, which eventually lead to leakage. If the problem of deformation cracks cannot be solved, the use of even the best waterproof materials cannot fundamentally solve the problem

[0024] (1) If figure 1 Shown, a kind of roof leak-proof structure layer is characterized in that: it comprises the foam layer 2 that is covered on the cement board 1 top of roof, the reticular layer 3 that spreads on the foam layer top, and casts on the reticular layer top and with The mesh layer is poured into an integrated cement covering layer 4 .
[0025] The cement covering layer is embedded with steel bars, and the mesh layer is steel wire or plastic or asbestos mesh layer.
[0026] As shown in Fig. 3 and Fig. 4, the cement covering layer is provided with broken seams 6 at appropriate intervals, and the sides of the broken seams are respectively provided with inverted U-shaped cement grooves 7 with upper arches, the bottom facing upwards, and the mouth facing downwards. Plastic foam 8 is filled in the channel of the U-shaped cement tank, and the tank body of the inverted U-shaped cement tank is composed of an inner layer mesh layer and an outer layer cement covering lay...

The present invention relates to one kind of antiseepage structure layer for roof and its forming process. The antiseepage structure layer for roof includes one foamed material layer on the roof cement slab, one netted layer on the foamed material layer and one cast cement layer to cover the netted layer integrally. The process of forming the antiseepage structure layer for roof includes the steps of: laying one foamed material layer on the roof cement slab, laying one netted layer on the foamed material layer, and casting one cement layer to cover the netted layer integrally. The present invention can prevent crack and leakage in roof caused by heat expanding and cold contracting effectively.
Description
technical field [0001] The invention relates to a leak-proof roof structure layer and a roof leak-proof treatment method for forming the structure layer. Background technique [0002] In the past, the leak-proof treatment of the roof was usually to increase the waterproof material layer or improve the compactness of the roof layer or to change the material of the roof layer. The leak-proof effect of this method was not very satisfactory, because the roof was exposed to wind and sun for a long time, and it was easy to Partial cracks are generated due to thermal expansion and cold contraction deformation, which eventually leads to leakage. If the problem of deformation cracks cannot be solved, the use of even the best waterproof materials cannot fundamentally solve the problem. Contents of the invention [0003] The object of the present invention is to provide a roof leak-proof structural layer and a roof leak-proof treatment method for forming the structural layer, which c...
