Embodiment Construction

[0031] The present invention will be described in further detail below.

[0032] The construction method of a roof waterproof project disclosed in the present invention includes the following steps:

[0033] S1. Repair the leveling layer, check the construction quality of the leveling layer before construction, repair the local unevenness, sanding, peeling, cracks, and pre-buried instability that appear in the leveling layer, and apply a layer of mixing on the surface of the leveling layer. Fill the cement mortar with glue 107 and smooth it, and fill the special parts of the roof with the cement mortar mixed with glue 107 to finally form the base layer for the first waterproof layer; after the leveling layer is dry, use a waterproof membrane to cover it On the surface of the base layer, let it stand for 2 to 3 hours until there is no watermark on the surface of the base layer where it is covered, and then start painting the first waterproof layer.

[0034] S2. Paint the first waterp...

Abstract

The invention relates to a waterproofing roof engineering construction method. The method comprises the following steps: S1. repairing a leveling layer; S2. brushing a first waterproof layer, whereinthe first waterproof layer is formed by brushing a base layer by polyurethane cement-based waterproof paint; S3. paving a second waterproof layer, wherein the second waterproof layer is formed by paving a waterproof coil on the first waterproof layer after the paint is dried to form a film; S4. brushing a third waterproof layer, wherein the third waterproof layer is formed by brushing the upper surface of the second waterproof layer by the polyurethane cement-based waterproof paint; and S5. paving a protective layer. The method has the advantages that three layers of waterproof measures are adopted for the roof, the tolerance for paving defects is strong, the durability of the waterproof layers is increased, rainwater can hardly enter the roof surface from the gap at special parts of the roof, which have good waterproof effect, and the risk of rainwater infiltration is reduced.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of roof waterproofing engineering. Background technique [0002] Roof waterproofing is a very important project in house construction. The quality of roof waterproofing works is directly related to the service life of the building and also affects people's normal life. [0003] In the existing roof waterproofing project, the main construction method is to bond the waterproof layer on a large area of ​​the roof. However, it is suitable for roofs with uneven surfaces such as cornices, gutters, gutters, water downs, and connecting structures protruding from the roof. In the paving process of special parts, paving defects are easy to appear, and the waterproof effect is poor. Summary of the invention [0004] The purpose of the present invention is to provide a roof waterproof project construction method with better waterproof effect on special parts of t...
