Description

Composite paving equipment for self-adhesive waterproof coiled material and building construction method

Technical Field

Background

With the vigorous development of the building industry, the number and the form of underground structures and high-rise buildings are more and more, and the requirements on the construction quality, the construction efficiency and the safety and environmental protection of the building waterproof engineering are also improved year by year. However, the leakage problem of underground structures, roofs and other parts of old and even newly built construction projects is serious, and the service function and the safe service life of the buildings are directly influenced. In order to deal with the problem of endless leakage, the building waterproof material is developed from the original single asphalt felt to the current waterproof coiled material, waterproof paint, rigid waterproof plate, water stop and the like, and a waterproof system is also developed from the original single material to a multilayer waterproof system compounded by a plurality of waterproof materials, so that the limitation of single material performance is broken through, the complementary performance and the synergistic effect of the advantages of the materials are exerted, and the reliability of the building waterproof system is improved.

The composite construction system of the waterproof coating and the waterproof coiled material is most widely applied, and particularly, the waterproof performance is particularly outstanding in the composite paving construction system of the non-cured rubber asphalt waterproof coating and the self-adhesive waterproof coiled material. The non-cured rubber asphalt waterproof coating has high-strength bonding capability on various base layers with different properties, has good elastic-plastic performance and creep performance, can effectively make up for the defects of the base layers in a viscous state after construction, realizes integral sealing on the base layers, can be bonded and compounded with the waterproof coiled material, has strong adaptability to cracking or stretching of the base layers, cannot transfer the stress of the base layers to the waterproof coiled material, and has high waterproof reliability. The self-adhesive waterproof coiled material does not need hot melting operation during construction, a coating layer cannot be damaged, the risks of environmental pollution and fire disasters do not exist, and safety and environmental requirements are guaranteed.

When the complex system is constructed, the non-cured rubber asphalt waterproof coating needs to be firstly blade-coated or sprayed on the base layer to form a coating layer with a certain thickness, and then the self-adhesive waterproof coiled material is quickly paved on the coating layer in a very short time so that the waterproof coiled material and the coating layer are firmly adhered together. The existing artificial pavement mode has more disadvantages: if the qualification and the proficiency of constructors are different, the construction quality and the construction efficiency are difficult to ensure; the coating thickness of the non-cured rubber asphalt waterproof coating is 1-2mm, the thickness is difficult to be uniform in manual operation, and the phenomenon of bottom exposure or accumulation exists; the coating width of the coating needs to be consistent with that of the waterproof coiled material so as to avoid the defects of pollution or full adhesion of a coating layer, the fine construction is difficult to achieve through manual operation, and the coating waste or missing coating phenomenon exists; the manual operation needs the constructors to squat or bend over to lower the head, the labor intensity is high, the posture is difficult to be affected, and the long-time operation is difficult. Although some simple waterproof roll paving devices exist at present, the devices do not consider the overlapping problem of a waterproof coating and waterproof roll composite system, and need manual operation or manual auxiliary operation, and the defects also exist. Therefore, it is urgently needed to develop a novel composite paving device for self-adhesive waterproof rolls to solve the above problems.
