Waterproof construction method for building roof

Abstract

The invention discloses a waterproof construction method for a building roof. The waterproof construction method comprises the following steps that firstly, on-site inspection of a leakage part of theroof is carried out, the leakage part is determined, the reason is ascertained, and the repairing processes are determined, wherein the specific steps include that firstly, multiple water separatingtrenches are dug in the roof to prevent water flowing in a roof insulation layer; the two sides of each water separating trench are plugged with a leakage stoppage material, macromolecule waterproof rolled materials are pasted, and therefore waterproof layers are made; and backfill of insulating layers of the water separating trenches is carried out, and when filling is carried out to be about 4 cm away from a leveling layer, inorganic aluminum salt water-proofing agent doped cement mortar is used as the leveling layer. By means of the waterproof construction method for the building roof, thetrenches are dug in the roof, the trenches are filled with a waterproof material, therefore rainwater is difficult to permeate to other places through an insulation layer box, and occurrence of waterleakage at multiple places is avoided; and the leveling layer is provided with separation seams and is filled with a sealing material, so that the rainwater is difficult to diffuse in the leveling layer, the rainwater diffusion area is limited, and control over permeation of the rainwater is facilitated.

Description

technical field [0001] The invention relates to the technical field of building waterproofing engineering, in particular to a building roof waterproofing construction method. Background technique [0002] Generally, a soft waterproof layer and a rigid cement layer must be laid on the roof for waterproofing, and the construction method must be strictly followed to ensure that the roof is effectively waterproof for decades. However, due to lack of maintenance and maintenance measures, the roof of the house is aging and damaged, thus The rainwater penetrates the roof through the waterproof layer, or there are cracks between the parapet and the roof, which causes rainwater to penetrate and cause the roof to leak. [0003] In the existing technology, the waterproof coiled material is laid on the roof, and the waterproof layer is laid on the roof by hot-melt paving or cold bonding method, so that the waterproof coiled material is attached to the roof surface, and the waterproof co...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a waterproof construction method for building roofs, which solves the problem of rainwater permeating into the roof after aging and damaged waterproof coiled materials, and the rainwater quickly accumulates in the insulation layer of the roof and Spread to other places, resulting in water leakage in many places on the roof, and the waterproof membrane often appears hollow during the laying process. As the temperature increases, the internal steam pressure will be very high, which will cause Break the waterproof membrane to reduce the use time of the waterproof membrane
