Technical Field

[0001] The utility model relates to the field of building boards, in particular to a double-insulation layer building wall without requiring disassembly of formwork. Background Art

[0002] In the current construction industry, concrete is widely used to build various buildings. However, the concrete pouring process usually requires multiple steps, including building formwork, pouring concrete, and removing formwork. Especially in the case of multi-layer pouring, these steps need to be repeated, resulting in low construction efficiency, extended construction period, large yard area, and increased ineffective construction costs.

[0003] In addition, building formwork is an indispensable tool in the concrete pouring process. At present, building formwork is mostly made of bamboo, wood, steel and other materials. However, these materials have some problems. For example, bamboo and wood formworks have a short service life, are easily deformed and damaged, and bring burdens to the environment; while steel formworks have a long service life, but are heavy and have low assembly efficiency, which brings inconvenience to construction.

[0004] With respect to the above-mentioned prior art, the inventors found that the existing building formwork is cumbersome to assemble and has a complex structure, and the building formwork is made of different materials and has poor performance, resulting in poor thermal insulation and convenience of the building formwork.
