Description

Technical Field

[0001] This utility model relates to the field of passive ultra-low energy consumption building construction, specifically a double-coat aerogel thermal insulation system structure. Background Technology

[0002] The exterior walls account for the largest proportion of heat loss in a building envelope, approximately 30% of the total building's heat consumption. Exterior wall insulation coatings can effectively prevent thermal bridging, thus helping to ensure indoor thermal stability. Existing exterior wall insulation structures generally consist of an insulation layer, a protective layer, and fixing materials. Typically, waterproof cement mortar is applied to the wall as a protective layer, then a wire mesh is installed as a fixing material, and finally, insulation boards are fixed on top as the insulation layer. However, existing exterior wall insulation structures cannot simultaneously possess excellent insulation performance, long service life, and superior fire and water resistance. To meet the energy-saving requirements of ultra-low energy consumption housing, a superior insulation system with excellent insulation performance, long service life, and water-repellent and fire-resistant properties is needed. Utility Model Content

The thermal insulation system includes, from the base wall outwards, a thermal insulation non-removable template layer, a plastering mortar composite alkali-resistant fiberglass mesh layer, a flexible putty layer for aerogel thermal insulation coating, a primer layer for aerogel thermal insulation coating, an intermediate layer for aerogel thermal insulation coating, a primer layer for aerogel thermal insulation coating, and a topcoat layer for aerogel thermal insulation coating.

[0005] Preferably, a connector is pre-embedded in the base wall, and the thermal insulation and non-removable template layer is disposed on the connector.

[0006] The connectors embedded in the base wall are arranged in a quincunx pattern and are tied and fixed to the steel bars in the base wall.

[0007] Preferably, the longitudinal and transverse spacing of the connectors pre-embedded in the base wall is no more than 500mm.

[0008] Preferably, a limiting device is provided in the base wall, and the connection distance between the thermal insulation non-removable template layer and the base wall is controlled by the limiting device.

[0009] Preferably, the thermal insulation template layer is reinforced by connecting the thermal insulation templates with U-shaped fasteners, and the vertical spacing of the U-shaped fasteners is no more than 500mm.

[0016] The base wall ① and the thermal insulation removable formwork layer ② are constructed together, the connecting piece 9 of the thermal insulation removable formwork is embedded during the construction of the base wall, the connecting piece protrudes from the base wall, and the protruding length satisfies the hanging construction of the thermal insulation removable formwork. The embedded connecting pieces 9 in the base wall are arranged in a plum blossom shape and are fixed by being bound with the steel bars in the base wall. The longitudinal and transverse arrangement spacing of the embedded connecting pieces in the base wall is not greater than 500 mm. Limiting clamping pieces (not shown in the figure) are arranged in the base wall, and the connecting distance of the thermal insulation removable formwork layer and the base wall is controlled through the limiting clamping pieces. The thermal insulation formwork is connected and reinforced through U-shaped fasteners (not shown in the figure), and the vertical spacing of the U-shaped fasteners is not greater than 500 mm.

[0017] After the construction is completed, the surface mortar composite alkali-resistant glass fiber mesh layer ③ is constructed, a layer of surface mortar is first brushed on the thermal insulation removable formwork layer ②, the alkali-resistant glass fiber mesh is then pressed into the surface mortar layer, and then a layer of surface mortar is brushed again, so that the alkali-resistant glass fiber mesh is fixed in the surface mortar layer to form the surface mortar composite alkali-resistant glass fiber mesh layer ③.

[0018] Then the flexible putty layer ④ of aerogel thermal insulation coating is constructed, and before the construction of the flexible putty layer, the interface agent needs to be used to treat the plastering mortar layer in the thin plastering mortar composite alkali-resistant glass fiber mesh layer ③, so that the plastering mortar layer is smooth and flat.
