Abstract
The utility model discloses a roofing waterproof layer crack control structure, including prefabricated roof boarding, adjacent prefabricated roof boarding end seal department sets up the buffer layer, the buffer layer is for spreading dry first waterproofing membrane on adjacent prefabricated roof boarding end seam, first waterproofing membrane's width is greater than the wide more than 8 times of adjacent prefabricated roof boarding end seam, bond second waterproofing membrane on the buffer layer, second waterproofing membrane's width is greater than first waterproofing membrane's width and its both sides respectively towards first waterproofing membrane both sides edge outside extension at least 6cm, the part of the outside extension of second waterproofing membrane bonds and laminates on prefabricated roof boarding. The roof waterproof layer anti-cracking structure reduces cracks and avoids leakage.
Description
The technical field is as follows:
the utility model relates to a roof waterproof layer crack control structure.
Background art:
in the existing building, because the waterproof coiled material is completely adhered and attached to the prefabricated roof panel, cracks and node cracks are easy to occur along the end of the prefabricated roof panel in the waterproof layer, so that leakage is caused.
The utility model has the following contents:
the utility model aims to solve the technical problem that a thereby provide a roofing waterproof layer crack control structure of seepage is avoided to reducible crack.
The technical solution of the utility model is, a roofing waterproof layer crack control structure is provided, including prefabricated roof boarding, adjacent prefabricated roof boarding end seal department sets up the buffer layer, the buffer layer is for spreading the first waterproofing membrane on adjacent prefabricated roof boarding end seam futilely, first waterproofing membrane's width is greater than the wide more than 8 times of adjacent prefabricated roof boarding end seam, bond second waterproofing membrane on the buffer layer, second waterproofing membrane's width is greater than first waterproofing membrane's width and its both sides respectively towards first waterproofing membrane both sides edge outside extension at least 6cm, the part of the outside extension of second waterproofing membrane bonds and laminates on prefabricated roof boarding.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: through setting up first waterproofing membrane as the buffer layer, can reduce the fracture of second waterproofing membrane to reduce the seepage risk.
Preferably, the width of the first waterproofing membrane is 20cm, and the width of the second waterproofing membrane is 35 cm.
Furthermore, first waterproofing membrane and second waterproofing membrane are APP modified asphalt waterproofing membrane.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1, a roof waterproof layer anti-cracking structure comprises prefabricated roof panels 1, wherein a buffer layer is arranged at the end sealing position of each adjacent prefabricated roof panel 1, the buffer layer is a first waterproof coiled material 2 laid on the end seam of each adjacent prefabricated roof panel in a dry mode, the width of the first waterproof coiled material 2 is more than 8 times larger than the width of the end seam of each adjacent prefabricated roof panel, a second waterproof coiled material 3 is bonded on the buffer layer, the width of the second waterproof coiled material 3 is larger than the width of the first waterproof coiled material 2, two sides of the second waterproof coiled material respectively extend outwards for at least 6cm towards the edges of two sides of the first waterproof coiled material, and the outwards extending part of the second waterproof coiled material 3 is bonded and attached to the prefabricated roof panels by using. In this embodiment, considering that the width of the end seam of the prefabricated roof panel is about 1cm, the width of the first waterproof roll is 20cm, and the width of the second waterproof roll is 35 cm. And moreover, the APP modified asphalt waterproof coiled material with high elongation is selected for the first waterproof coiled material and the second waterproof coiled material. First waterproofing membrane is empty to be spread and uses as the buffer layer on prefabricated roof boarding's end seam to can effectively reduce the fracture of second waterproof layer, and use as reserve layer, thereby reduce the seepage risk.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
