Problems solved by technology

[0004] The disadvantages of the above structure are: the layers of organic and inorganic materials are not firmly bonded, and the phenomenon of drumming and falling off due to the inconsistent thermal expansion and contraction of the two, the process is complicated, cannot meet the needs of popular construction, the cost is high, and the fire protection level cannot be achieved. Class A fire protection requirements issued by the Ministry of Public Security
The waterproof fortification is not ideal enough, causing the common problem of water seepage and falling off

Embodiment Construction

[0016] like figure 1 As shown in the figure, an external wall waterproof and thermal insulation integrated structure includes a mortar bonding layer 1, a foam concrete thermal insulation board 2, an anti-cracking mortar plastering layer 3, and a polymer cement glue arranged from the inside to the outside of the external wall base 100. Adhesive layer 4, polyethylene polypropylene waterproof membrane layer 5, plastering anti-cracking mortar protective layer 6, finishing layer 7.

[0017] The mortar bonding layer 1 requires that the base 1:3 cement mortar leveling layer 200 applied on the surface of the outer wall base 100 should be flat, and the average thickness of the mortar bonding layer 1 should be 5mm, and the thinnest part should not be less than 3mm.

[0018] Foamed concrete insulation board 2, also known as cement foam insulation board, inorganic A-level waterproof insulation board, the thickness of the insulation board should not be less than 30mm, and its compressive s...

Abstract

An outer wall waterproof and heat-preservation integrated structure comprises a mortar bonding layer, a foam concrete heat-preservation plate, an anti-cracking mortar plastering layer, a polymer cement bonding layer, a polyethylene polypropylene fiber waterproof roll layer, a plastering anti-cracking mortar protective layer and a veneer layer arranged from inside to outside. The outer wall waterproof and heat-preservation integrated structure is high in construction speed. The materials in each layer are inorganic bonding materials, and the overall stability is good. The heat-preservation layer is arranged in the waterproof layer, the heat-preservation effect acts for a long time, and the inorganic materials do not burn and meet the A-level waterproof requirement. The outer wall waterproof and heat-preservation integrated structure is good in durability, has the same service life with a building, is low in comprehensive manufacturing cost, is small in construction difficulty and is easy to learn and implement.

Description

【Technical field】 [0001] The invention belongs to the technical field of building materials, and particularly relates to an integrated structure for waterproofing and thermal insulation of external walls. 【Background technique】 [0002] In the field of construction, as people have higher and higher requirements for building quality, the country's requirements for energy conservation, low carbon, and fire safety are also increasing. . The materials between the layers are not firmly bonded, the construction is complicated, the structural cost is high, the durability is poor, and the maintenance is difficult. [0003] At present, one solution of the exterior wall waterproof and thermal insulation structure in the industry is: from the inside to the outside, it is a polyurethane moisture-proof primer, a rigid polyurethane foam insulation layer, a polyurethane interface mortar, a rubber powder polystyrene particle slurry leveling layer, and an anti-cracking mortar. Composite fi...
