Straw is insulation material's precast concrete sandwich wall body

The utility model relates to a straw is insulation material's precast concrete sandwich wall body belongs to the building materials field. The straw heated board is located between internal lobe concrete panel and the siphonal lobe concrete panel, and the inboard reinforcing bar net of individual layer is located internal lobe concrete panel, and double -deck outside reinforcing bar net is located siphonal lobe concrete panel, and straw heated board, lower extreme and double -deck outside two -way steel bar net clasp joint and inflection are passed with the inboard reinforcing bar net clasp joint of individual layer, middle part in U type or V type basalt fiber muscle connecting piece upper end. The advantage is novel structure, and wall connection's reliability both can have been guaranteed to the U type of adoption or V type basalt fiber muscle connecting piece and straw heated board, internal lobe concrete panel and siphonal lobe concrete panel's connected mode, can avoid the wall body problem of cold and
