Dual-keel heat preservation outer wall structure

The invention discloses a dual-keel heat preservation outer wall structure. The structure comprises an outer frame structure formed by a formwork and further comprises an inner vertical keel unit andan outer vertical keel unit which are arranged in the outer frame structure. The formwork is filled with light aggregate concrete, and the inner vertical keel unit and the outer vertical keel unit areconnected through a connecting part. The dual-keel heat preservation outer wall structure is good in heat preservation and heat insulation effect, the cold bridge phenomenon appearing in the wall isavoided, and the heat preservation and insulation effect of the wall is greatly improved. 本发明公开了一种双龙骨保温外墙结构，包括模板组成的外框结构和设置在所述外框结构内的内竖向龙骨单元与外竖向龙骨单元，所述模板内填充有轻集料混凝土，所述内竖向龙骨单元与所述外竖向龙骨单元通过连接件连接。本发明的双龙骨保温外墙结构保温隔热效果好，避免了墙体出现冷桥现象，大大提高了墙体的保温隔热效果。
