Large-area foamed concrete cast-in-place heat preservation structure and construction formwork system

The utility model discloses a large-area foamed concrete cast-in-place heat preservation structure which comprises a foamed concrete heat preservation layer, a supporting assembly arranged in the heat preservation layer and a protection layer used for protecting the heat preservation layer, and the supporting assembly is connected with the protection layer. The supporting assembly and the protective layer are adopted to protect the heat preservation layer, and the situation that the heat preservation layer is damaged due to pressure, and the heat preservation effect is reduced due to bubble penetration in concrete is avoided. 本实用新型公开了一种大面积发泡混凝土现浇保温结构，包括发泡混凝土保温层、设在保温层中的支撑组件和用于保护保温层的防护层，所述支撑组件与防护层连接。本实用新型采用支撑组件和防护层对保温层进行保护，避免保温层受压损坏，混凝土中的气泡贯通而降低保温效果。
