Description

Technical Field

[0001] The utility model relates to a fireproof and low - energy - consumption non - removable thermal insulation formwork, belonging to the technical field of building materials. Background Art

[0002] The non - removable thermal insulation formwork is cast integrally with the building structure, eliminating the formwork removal link, which can significantly improve the construction efficiency and reduce the building cost. In order to ensure the strength and thermal insulation performance of the non - removable formwork, the currently used non - removable thermal insulation formwork generally includes a thermal insulation board and a protective layer. The thermal insulation board and the protective layer cooperate with each other to make the formwork reach the required strength and fireproof and thermal insulation performance. In order to further improve the strength of the non - removable formwork, the prior art usually sets wire mesh sheets in the protective layers on both sides of the thermal insulation board respectively, and connects the wire mesh sheets in the protective layers on both sides through the web wires passing through the thermal insulation board. However, the web wires passing through the thermal insulation board and the wire mesh sheets on both sides will form a cold - heat bridge effect, which has an adverse impact on the thermal insulation performance of the building structure.
