With the development of China's building technology in recent years, large-span, light-weight, and high-rise buildings have increased, causing major changes in the deformation of roof structures. The emergence of roofs such as parking lots, playgrounds, and gardens has also greatly increased roofing functions. Today, Xiao Bian talked about the waterproof construction of the roof, to see what problems should be paid attention to the construction of the roof waterproofing project.
Roof waterproof construction
To fundamentally solve the problem of seepage of water in roofs of existing buildings, it is necessary to proceed from the aspects of design, construction, materials, management, and maintenance of the waterproofing works, and carry out system management and comprehensive prevention and control. In order to improve the quality of waterproofing projects and prevent leakage, we will start from construction, strictly control the quality of materials, improve design standards and strengthen management, and adopt specific measures for comprehensive prevention and control.
Material selection
In the treatment of roof seepage water, we should vigorously promote the application of new types of waterproof materials. We should first select advanced polymer-modified bituminous membranes and coatings, synthetic polymeric coils and coatings, and elasto-plastic seals with relatively advanced technologies and superior performance. Materials and new rigid waterproof material. In the current mixed situation of the waterproof material market, the material quality must be strictly controlled. For the waterproof material entering the construction site, it must not only meet the national or industrial standards, but also have the factory certificate and the material quasi-use certificate. The re-inspection of unqualified materials is not required, and the application of fake and shoddy products to the leakage water treatment project shall be strictly prevented.
Roof waterproof design
The design should be based on the nature of the building, engineering characteristics, degree of importance and the use of features for waterproofing. Due to the variety of waterproof materials, various performances, different application scopes, and widely varying prices, we must carry out roof waterproof design and material selection in accordance with the principle of “according to local conditions, material selection according to demand, combination of prevention and drainage, rigidity and flexibility, and overall sealingâ€. . According to the local maximum and minimum temperature, daily temperature difference, roof slope, the form of waterproof layer (exposed or non-exposed) and the size of the structure and other specific circumstances, select the appropriate waterproof material, determine the appropriate construction program.
Construction is the key
Leakage water treatment project construction is a technically strong, high-standard waterproof material reprocessing process, so it must be trained by a professional technician, familiar with construction specifications and waterproof material performance characteristics and application scope of a well-trained professional waterproof construction team Conduct construction. In the construction process, we must strictly abide by the national standards and regulations, conscientiously implement the process standards, meticulous and careful operation, so as to ensure the quality of the project.
Strengthen management and maintenance
Strengthening management and maintenance is an important measure to reduce the leakage rate of the roof and prolong the service life of the waterproof layer.
Due to the gradual aging of materials, the repeated impact of various deformations, the effects of freezing and dripping, the scouring of rainwater, the artificial damage during use, and the blocking of drainage channels due to the accumulation of dust and dust, the use of factors such as the gradual aging of materials after the completion of acceptance of waterproof works The waterproof layer is damaged and leads to leakage. Therefore, strengthening management and maintenance is an important measure to improve the quality of waterproofing projects. Regular maintenance and maintenance of the roof, such as taking a comprehensive cleaning inspection of the waterproof layer before the onset of the rainy season each year and before entering the winter, and finding that the damaged area is promptly repaired, will reduce the leakage rate of the roof, reduce repairs, save costs, and prolong the waterproofing. The useful life of layers is of great significance.
Problems that Should Be Paid Attention to in Construction of Roof Waterproof Engineering
In the construction of polyester cloth, the construction environment temperature should not be lower than 5 °C, construction under rain, snow, fog, and five winds and above conditions is strictly prohibited.
The grass-roots level must be firm and flat, with no unevenness or severe cracks. When checked with a 2M ruler, the clearance must not exceed 5 mm. The depth of the pit must not exceed
3MM for all holes, cracks must be filled with mortar and smooth, after standing for 3 to 4 hours, lift the grassroots site and no watermark can be seen on the polyester cloth.
Before the polyester fabric is applied, the base layer should be cleaned and there should be no floating ash.
The selection of the primary treatment agent should be compatible with the properties of the polyester cloth, and the spray should be uniform.
With the principle of “first away from the bottom, first away from the first, and later far and nearâ€, the site where the nodes and the drainage are concentrated should be established first.
The polyester cloth should be laid flat and straight. The overlap size is accurate and must not be distorted. The overlapped area of ​​the polyester cloth should be modified with overflowing hot melt, and the interface should be scraped immediately.
Pipes, equipment, and embedded parts shall be installed before the construction of the polyester cloth. It is strictly forbidden to make holes or place hard and heavy objects on the waterproof layer of the polyester cloth that has been made. For all angles of yin and yang, apply 1:3 cement mortar to make R=50 or 80*80(mm).
After the construction of the waterproofing project is completed, the roofing water or water confinement test shall be used for inspection to determine whether there is no accumulation of water and no leakage.
Xiao Bian concludes : The relevant contents of the roof waterproof construction will be introduced to this, and I hope to help you. More exciting information is on this site.
