Roof water-proofing construction method

Abstract

The roofing water-proofing construction method includes the following steps: firstly, sticking a clock over the edge of roof with PVC oil paste, coating a layer of PVC oil paste on the cloth laid on the roof, laying another layer of cloth on the PVC oil paste, then laying a layer of water-proofing coil material on the PVC oil paste layer sandwiched between the above-mentioned two layers of clothes, adhering the edge of the water-proofing coil material, brushing PVC oil paste on overlapped places of water-proofing coil material, laying cloth and more brushing the PVC oil paste so as to obtain one integrated roofing water-proofing layer.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a roof waterproof construction method. Background technique [0002] At present, the waterproof materials used for building waterproofing mainly include SBS waterproof membrane, or APP waterproof membrane, or polyethylene composite waterproof membrane, or ternary butyl rubber waterproof membrane, because SBS waterproof membrane and APP waterproof membrane belong to asphalt materials It has certain limitations, especially in areas with relatively large temperature differences. In the case of roof deformation, water leakage will occur in parapets, deformation joints, and rainwater outlets. These two materials are liquefied gas furnaces or blowtorch baking materials. When the bitumen itself is baked and pasted, if it is fully baked, the base surface will expand through the gas, and the waterproof layer will easily break; in addition, the materials of these two waterproof materials...

[0002] At present, the waterproof materials used for building waterproofing mainly include SBS waterproof membrane, or APP waterproof membrane, or polyethylene composite waterproof membrane, or ternary butyl rubber waterproof membrane, because SBS waterproof membrane and APP waterproof membrane belong to asphalt materials It has certain limitations, especially in areas with relatively large temperature differences. In the case of roof deformation, water leakage will occur in parapets, deformation joints, and rainwater outlets. These two materials are liquefied gas furnaces or blowtorch baking materials. When the bitumen itself is baked and pasted, if it is fully baked, the base surface will expand through the gas, and the waterproof layer will easily break; in addition, the materials of these two waterproof materials are relatively hard, and they are very difficult at the parapet and air vents. It is difficult to do waterproof well; while the polyethylene composite waterproof membrane uses a mixture of cement and 107 glue as an adhesive, and then coats a layer of cement on the surface. Due to the relatively large temperature difference in the northern region of our country, the waterproof layer will It is easy to break; the ternary butyl rubber waterproof membrane is currently the most anti-aging waterproof material. It is relatively soft, and its tensile strength and elongation are relatively strong. Cause damage to the roof, the current roof waterproof construction method is to spread the waterproof membrane on the roof, the waterproof effect is poor
