Description

External wall insulation and waterproof structure

technical field

The utility model belongs to a waterproof structure, in particular to a waterproof and thermal insulation structure for walls.

Background technique

The waterproof protective layer of the thermal insulation exterior wall usually has the following situations: 1. When the paint finish is used, the waterproof layer can use polymer cement waterproof mortar or ordinary waterproof mortar. If the crack-resistant mortar layer of the insulation layer meets the performance index requirements of polymer cement waterproof mortar, it can also be used as a waterproof protective layer. Set between the insulation layer and the paint finish, the thickness of the emulsion polymer waterproof mortar should not be less than 5mm, and the thickness of the dry powder polymer waterproof mortar should not be less than 3mm; 2. When the block finish is used, the waterproof layer should be made of polymer cement Mortar, the thickness should meet the provisions of paragraph 1 of this article. If the crack-resistant mortar layer of the insulation layer meets the performance index requirements of polymer cement waterproof mortar, it can also be used as a waterproof protective layer; 3. The waterproof layer of polymer cement waterproof mortar should be reinforced with alkali-resistant glass fiber mesh or hot-dip galvanized steel wire mesh , and use anchor bolts to fix it in the structural wall; 4. When the curtain wall finish is used, the waterproof layer should be set between the leveling layer and the curtain wall finish. The waterproof layer should use polymer cement waterproof mortar, polymer cement waterproof coating, Polymer emulsion waterproof coating, polyurethane waterproof coating or waterproof vapor permeable membrane. The thickness of waterproof mortar shall comply with the provisions of paragraph 1 of this article, and the thickness of waterproof coating shall not be less than 1.0mm. When the insulation layer of the external wall is made of mineral wool insulation material, the waterproof layer should use a waterproof vapor-permeable membrane. But there are still deficiencies in practical application.

Utility model content

The purpose of this utility model is to solve the above problems and propose a thermal insulation and waterproof structure of the outer wall. Strong features.

The purpose of this utility model is achieved through the following technical solutions: the outer wall insulation and waterproof structure is provided with a reinforced concrete poured wall, which is characterized in that: the outer layer of the wall is smoothed with cement mortar to form a leveling layer, and the Anchor bolts and gaskets are used to fix the insulation layer outside the leveling layer. The insulation layer is made of fiber-shaped insulation blocks made of inorganic silicate rock. The fiber-shaped insulation blocks are soaked in cement to form a stable shape with bubbles inside. The thermal insulation block, the thermal insulation layer is coated with a waterproof layer, and the waterproof layer is coated with a decorative paint layer.

The waterproof layer is composed of waterproof glue, polypropylene cloth, and waterproof mortar layer, that is, the polypropylene cloth is pasted on the insulation layer with waterproof glue, and then waterproof mortar is applied on the polypropylene cloth.

The utility model adopts anchor bolts and pads to fix the insulation layer
