Abstract
Description
Technical Field
[0001] The utility model relates to the field of building materials, and particularly relates to an assembled composite thermal insulation wall panel. Background Art
[0002] In the process of traditional building wall construction, the commonly used methods are on-site casting or masonry. This method not only has low construction efficiency, but also due to the uncertainty of on-site construction conditions, it is often difficult to ensure the thermal insulation performance of the wall and the uniform stability of the structure. In addition, after the traditional wall materials complete the structure construction, secondary thermal insulation treatment is usually required, that is, additional thermal insulation materials are added outside the wall. This process not only increases the construction complexity and cost, but also prolongs the entire construction period.
[0003] Specifically, for the cast-in-place wall, formwork needs to be erected first, then concrete is mixed and poured on-site, and then the formwork needs to be removed and cured. All these steps require a large amount of time and labor. For the masonry wall, a large number of bricks or blocks and corresponding mortar are required, and workers need to build the wall piece by piece. This method has a high labor intensity and low efficiency.
[0004] The secondary thermal insulation treatment is usually to apply or paste thermal insulation materials on the surface of the wall after it is built. This subsequently added thermal insulation layer is often separated from the wall itself, and is prone to phenomena such as peeling and falling off, which affects the aesthetics and thermal insulation effect, and increases the maintenance cost.
[0005] Traditional building wall materials need to be constructed in multiple layers on-site, with cumbersome processes, difficult quality control, especially difficult to ensure the uniformity and stability of the thermal insulation performance, and also require secondary thermal insulation treatment, which increases the construction cost and cycle, and has a high maintenance cost. With the increasing requirements of the construction industry for energy conservation, emission reduction and construction efficiency, this traditional wall can no longer meet the needs of modern buildings.
