Problems solved by technology

Since the objects of leak repair are mainly existing buildings or structures, the previous repair methods are often incomplete, improper repair methods, or use of unreasonable materials, etc., resulting in poor repair effect and secondary leakage on the roof
Once leakage occurs in larger projects in existing life, the repair is generally more complicated and the repair cost is also higher. If it cannot be arranged reasonably, it will inevitably cause greater losses

Embodiment 1

[0030] Example 1 : Construction method for leak repair of membrane waterproof roof

[0031] The method includes: leak investigation, repair plan design, grass-roots treatment, detailed repair, large-scale repair, water storage test, management and maintenance and other processes.

[0032] (1) Leak investigation

[0033] The leak site investigation steps are as follows:

[0034] (1) Investigation content: analyze the environment around the location of the project, the use conditions, and the impact of climate change on the project; find the leak point, determine the location and current situation of the leakage water; the change law of the leakage water; the quality of the waterproof layer at the leakage site Current status and degree of damage; current status of detailed waterproofing; analysis of the cause of leakage, scope of influence, evaluation of structural safety, energy conservation of the outer enclosure structure and damage to other functions; submit a written rep...

Embodiment 2

[0085] Example 2 : Waterproof roof leakage repair construction method

[0086] The construction method is the same as that of Example 1, except that the coils used are synthetic polymer waterproof coils, the coating is sprayed polyurea waterproof coating, and the sealing material is butyl rubber waterproof sealing tape.

Embodiment 3

[0087] Example 3 : Construction method is identical with embodiment 1, difference is:

[0088] The membrane used is waterproof membrane without asphalt, the coating is sprayed polyurea waterproof coating, and the sealing material is butyl rubber waterproof sealing tape.

[0089] The specific proportion of the waterproof membrane without asphalt is as follows in parts by weight: 65 parts of rosin, 50 parts of vegetable oil, 40 parts of styrene-butadiene-styrene block copolymer, and 10 parts of talcum powder. Production method: use heat conduction oil heating equipment to heat, first add rosin, add vegetable oil when heated to 160-200 ° C, stir evenly; then add styrene-butadiene-styrene block copolymer, talcum powder, stir evenly That is, the waterproof membrane of the present invention is obtained. The construction method is the same as that of the modified asphalt coil.

Abstract

The invention relates to a method for repairing a leaked coiled-material water-proof roof. The method comprises the steps of basic layer processing, detail repairing, large-area repairing, and the like. The step of detail repairing comprises: repairing cracked gutters and eaves gutter coiled-materials, repairing flashing parts and repairing deformed joints. The step of large-area repairing comprises: paving water-proof coiled materials, repairing cracks on a coiled-material water-proof layer, repairing the raised edges of a joint opening, repairing a raised part, and the like. The whole repairing scheme of the invention has the advantages of scientific design, reasonable system, overall prospection, rigorous analysis, practicability and good construction effect, and ensures that leaked houses can be effectively repaired. In the method, the materials, construction manner, construction environment, and the like, are all comprehensively considered. The construction cost performance is high and the use range is wide. The construction method is safe and environment-friendly, can meet the demands of building use and safety, can ensure that the manpower, material resources and financial resources are saved, and is suitable for various repairing for the leaked coiled-material water-proof roof. The application and practice show that the construction condition of the method is in good condition.

Description

technical field [0001] The invention relates to a method for repairing roof leakage, in particular to a construction method for repairing leakage of a coiled material waterproof roof. Background technique [0002] At present, there are different degrees of water leakage in the membrane waterproof roof of housing construction in our country. There are many reasons for the leakage. The comprehensive analysis mainly includes four factors: design, construction, materials and use management. Since the objects of leak repair are mainly existing buildings or structures, the previous repair methods are often incomplete, improper repair methods, or use of unreasonable materials, etc., resulting in poor repair effect and secondary leakage on the roof . Once leakage occurs in larger projects in existing life, the repair is generally more complicated, and the repair cost is also higher. If it cannot be arranged reasonably, it will inevitably cause greater losses. Contents of the inve...
