Roof water-proof thermal-insulation construction technique

Abstract

The invention provides a roof water proof heat preserving and insulating construction technology, which includes the following procedures: the roof is cleaned and wetted; a thin layer of mixed dry powder is spread on the wet roof to form a thin combined layer; the crackle resistant anti-ageing soread is adopted to pave a crackle resistant anti-ageing layer on the micro thin combined layer; the water proof heat preserving and insulating soread is adopted to pave a water proof heat preserving and insulating layer on the crackle resistance anti-ageing layer; the crackle resistant anti-ageing preventive soread is adopted to pave a crackle resistant anti-ageing preventive layer on the water proof heat preserving and insulating layer; a layer of ceramic tiles is bonded on after the crackle resistant anti-ageing preventive layer is solidified, so as to form an outer protective layer; the water proof agent is adopted to sprinkle the outer protective layer and the layer is then left dry, and those are all for the procedures. With such a technology, the construction layer and the roof are firmly combined, with extremely good affinity and outstanding binding effect; in addition, the construction technology is scientific and reasonable, simple and easy, has outstanding water proof, heat preserving and insulating effects, and thoroughly solves the technical problems of roof leakage, hollowing and crackling.

Description

technical field [0001] The invention belongs to the field of roof waterproof, thermal insulation, and in particular relates to a roof waterproof thermal insulation construction process. Background technique [0002] Roof waterproofing, heat preservation and heat insulation have always been a construction problem that plagues people. The main problems are: [0003] 1. The base layer of the roof is paved with a mixture of fly ash, perlite powder, cement and water. The floor surface is not firmly bonded, and the crispness is serious, resulting in uneven volume shrinkage. Because of the high water absorption rate, thermal expansion is easy to occur Cold shrinkage, resulting in hollowing and cracking; [0004] 2. The leveling layer mostly uses perlite waterproof board or extruded plastic board. At present, there is no joint agent at the seam of perlite waterproof board, which is easy to seep water, while extruded plastic board has poor air permeability, and the moisture below is...

AI Technical Summary

Problems solved by technology

[0003] 1. The base layer of the roof is paved with a mixture of fly ash, perlite powder, cement and water. The floor surface is not firmly bonded, and the crispness is serious, resulting in uneven volume shrinkage. Because of the high water absorption rate, thermal expansion is easy to occur Cold shrinkage, resulting in hollowing and cracking;

[0004] 2. The leveling layer mostly uses perlite waterproof board or extruded plastic board. At present, there is no joint agent at the seam of perlite waterproof board, which is easy to seep water, while extruded plastic board has poor air permeability, and the moisture below is difficult to discharge, which is easy to generate heat. Expansion and contraction, and then lead to hollowing and cracking;

[0005] 3. Usually, steel wire mesh is laid on the perlite waterproof board or extruded plastic board, and it is directly covered with cement mortar. Because the two are not the same substance, there is no affinity at all. The construction is artificial. Once the interior is hollow, cracking will appear immediately. ;

[0006] 4. In order to be waterproof, the construction unit often makes various waterproof rolls on the thermal insulation layer and seals them with waterproof paste. It will have a waterproof effect within 1-2 years, but after 2 years, especially in the strong heat in summer and the sun's ultraviolet rays Under the damage of long-term exposure, coupled with severe freezing in winter, the outer waterproof membrane will soon age, causing cracks and water seepage;

[0007] 5. The parapet has always been a headache. Now most of them use waterproof rolls and special colloids to bond the parapet. After 2 years, it is easy to fall off. The reason is that the parapet absorbs a lot of heat and is bonded with colloid. It is easy to age when exposed to high temperature. Although the colloid is made of various fabrics as strong tendons, it cannot prevent the strong damage of sunlight and ultraviolet rays. Especially in hot weather, the colloid is easy to soften, and the weather is easy to make the colloid shrink and soften. If things go on like this, it is easy to cause The parapet colloid falls off, cracks and seeps
