Problems solved by technology

According to the requirements of the "Technical Regulations for Waterproof Engineering of Building Exterior Walls", the existing waterproofing of external walls can only set up the waterproof layer between the insulation layer and the base layer of the structural wall, not between the insulation layer and the surface layer. As a result, when the insulation board is fixed with fixing parts for external wall insulation, the anchor bolts used to fix the insulation layer will destroy the integrity of the waterproof layer between the base layer and the surface layer of the structural wall, resulting in hidden dangers of water leakage

When the anti-cracking mortar leaks and cracks, water will enter the insulation layer and thus enter the inner wall. When there is moisture in the insulation layer, the insulation layer will fall off due to the damage of the freeze-thaw cycle in autumn and winter, and...

Abstract

The invention discloses a building external wall waterproof and crack resistant thermal insulation structure. The building external wall waterproof and crack resistant thermal insulation structure comprises a wall base layer. A polymer waterproof mortar bottom layer is arranged on the wall base layer, the polymer waterproof mortar bottom layer is provided with a galvanized steel wire net, and thegalvanized steel wire net is provided with a polymer waterproof mortar surface layer; and the polymer waterproof mortar surface layer is provided with a thermal insulation layer, and the thermal insulation layer is provided with a polymer waterproof crack resistant mortar layer. According to the building external wall waterproof and crack resistant thermal insulation structure, compared with the prior art, the problem that the crack resistant strength of a building external wall is poor can be solved, the waterproof performance of the wall base layer is improved, the reinforcing effect of thewall base layer is achieved, the structure is simple, construction is convenient, the cost is low, and the service life is long.

Example Embodiment

[0019] Example 1: A waterproof and crack-resistant thermal insulation structure for building exterior walls, comprising a wall base layer 1, on which a polymer waterproof mortar bottom layer 2 is arranged, and the polymer waterproof mortar bottom layer 2 is away from the wall base layer 1 The side of the galvanized steel wire mesh 3 is provided with a polymer waterproof mortar surface layer 4 away from the wall base layer 1 of the galvanized steel wire mesh 3, and the polymer waterproof mortar surface layer 4 is away from the wall base layer 1 There is an insulation layer 5 on one side of the insulation layer 5, and a polymer waterproof and crack-resistant mortar layer 6 is provided on the side of the insulation layer 5 away from the wall base layer 1.

[0020] It should be noted that, through the above improvement, the ordinary mortar layer is changed to a polymer waterproof mortar layer, which can improve the waterproof effect. The anti-cracking mortar layer on the insulation layer is changed to a polymer waterproof and anti-cracking mortar layer 6 to avoid the use of After fixing the thermal insulation layer, the anchor bolts will affect the waterproof effect after the polymer waterproof mortar layer is penetrated by the anchor bolts. Setting a waterproof and anti-crack layer on the surface layer can prevent rainwater from entering the wall base layer.

[0021] The other parts of this embodiment are the same as the above-mentioned embodiment, so they will not be described again.

Example Embodiment

[0022] Example 2: The total thickness of the polymer waterproof mortar bottom layer 2, the galvanized steel wire mesh 3 and the polymer waterproof mortar surface layer 4 does not exceed 35mm; the polymer waterproof mortar bottom layer 2, the galvanized steel wire mesh 3 and the polymer waterproof When the total thickness of the mortar surface layer 4 exceeds 35 mm, the base layer of the wall is planted with reinforcement, and then the galvanized steel wire mesh 3 is installed; the galvanized steel wire mesh 3 is a hot-dip galvanized steel wire mesh.

[0023] It should be noted that through the above improvements, it is possible to effectively avoid the possibility of workers completing the polymer waterproof mortar layer at one time during the construction process, and the installation of steel wire mesh can effectively prevent the wall base from cracking; The polymer waterproof mortar layer of more than 35mm is reinforced with steel wire mesh after planting bars; the hot-dip galvanized steel wire mesh has the characteristics of thick coating, strong corrosion resistance and firm coating, and has a long service life; hot-dip galvanized The installation of steel wire mesh on the base of the external wall is exactly a reinforcement of the base of the external wall.

[0024] The other parts of this embodiment are the same as the above-mentioned embodiment, so they will not be described again.

Example Embodiment

[0025] Example 3: The polymer waterproof and crack resistant mortar layer 6 has a thickness of 3-5 mm; the polymer waterproof and crack resistant mortar layer 6 is constructed in two times.

[0026] It should be noted that through the above improvements, the thickness of the polymer waterproof and anti-cracking mortar layer 6 is 3-5 mm through two constructions, which can effectively avoid the occurrence of cracking caused by one construction.
