Waterproof construction method of roof of building

Abstract

The invention relates to a waterproof construction method of a roof of a building. The waterproof construction method specifically comprises steps as follows: (1) an organic silica sand blending solution is sprayed to silica sand, the silica sand is uniformly stirred, aired and dewatered, organic silica sand is formed and then paved on a structure layer of the roof, and an organic silica sand layer is formed after a slope is found; (2) cement, sand, stone and fibers are blended with the organic silica sand blending solution and stirred uniformly, and concrete prefabricated slabs are prepared for standby use; (3) a plurality of concrete prefabricated slabs are closely paved on the organic silica sand layer block by block, and a V-shaped groove is formed between two adjacent prefabricated slabs; (4) firstly, a silicone structural adhesive is extruded at the bottom of the V-shaped groove, and after the adhesive is cemented firmly, cement mortar is poured into the V-shaped groove until the motor is flush with the upper surface of the prefabricated slabs. By means of the method, the roof is long in service life and low in cost, causes no pollution, can effectively resist water, is not prone to cracking and water leakage and has proper waterproof, thermal insulation and heat preservation functions.

Description

technical field [0001] The invention relates to a building construction method, in particular to a waterproof construction method for a building roof. Background technique [0002] The roof is the main aspect of heat conduction, and its quality directly affects the indoor temperature, resulting in the common situation of cold in winter and hot in summer. The waterproof treatment of the roof of the house has always been a difficult problem in the construction field. At present, the commonly used waterproof membrane has a short service life, is not easy to guarantee the quality, pollutes the environment, and is expensive. Under the aging of materials and the alternating effects of cold and heat, The coiled material cracks, and rainwater easily enters under the coiled material, and due to the sealing effect of the coiled material, the leaked water is not easy to escape. After a few years, the roof surface is damaged by freezing, water leaks inside the house, and the thermal ins...

The waterproof treatment of the roof of the house has always been a difficult problem in the construction field. At present, the commonly used waterproof membrane has a short service life, is not easy to guarantee the quality, pollutes the environment, and is expensive. Under the aging of materials and the alternating effects of cold and heat, The coiled material cracks, and rainwater easily enters under the coiled material, and due to the sealing effect of the coiled material, the leaked water is not easy to escape. After a few years, the roof surface is damaged by freezing, water leaks inside the house, and the thermal insulation layer fails, resulting in indoor damage. Common conditions of cold in winter and hot in summer

In addition, due to the instability of concrete, it is very easy to crack, rigid waterproofing is not easy to succeed, and the number of maintenance and repairs is too many, so that residents are unwilling to buy the top floor.
