Description

Technical Field

[0001] The utility model relates to a concrete thermal insulation formwork disassembly-free structure. Background Art

[0002] The concrete insulation formwork non-removal structure is a composite insulation wall formed by the wall structure relying on insulation materials. It integrates insulation and wall maintenance functions. The wall does not need to take additional insulation measures to meet the current standard requirements. The exterior wall insulation and structural integration technology is suitable for high-rise, multi-story and low-rise residential buildings and public buildings in severe cold, cold and hot summer and cold winter areas with insulation requirements. It is an important measure to effectively solve the common quality problems of energy-saving insulation projects and fire safety. The pouring area between the inner insulation board and the outer insulation board in the concrete insulation formwork non-removal structure needs to be tied with wall steel bars. At present, when tying wall steel bars, it is easy to have loose connections. At the same time, there are twice as many joint steel bars in the steel bar overlap area. Too many steel bars occupy the cross-sectional area. The steel bars at the rod nodes are tied and cannot be released. The force transmission performance is poor. In addition, this process requires professional construction personnel to tie, and the construction progress is slow, which is not conducive to pouring and vibrating dense concrete, and will affect the quality and stability of the entire structure.
