Vertical connection: the bottom of the lower edge beam 6 is provided with a second notch 61, the top of the upper edge beam 9 is provided with a second convex opening 92, and when the two assembled wall body components are vertically connected, the second convex opening 92 of the edge beam and the second notch 61 are embedded.
To sum up, the utility model relates to an assembled self preservation temperature recycled concrete block wall and construction method thereof, from the structural design and the material optimization of building block, obtained one kind and collected energy-conserving useless, thermal-insulated and built-in pipeline in the building block masonry structure layer of an organic whole that keeps warm. The assembled self-heat-preservation recycled concrete block wall component is obtained by arranging the decorative layer and the beam column system on the outer side of the structural layer. The component solves the problems of accumulation of waste concrete, high energy consumption of a traditional wall body, pipeline confusion during decoration construction, secondary damage of the wall body and the like, has simple structure, reasonable design and good integrity, and improves the flexibility and the safety of building construction efficiency and later-stage decoration transformation.
The above contents are only for explaining the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical solution according to the technical idea of the present invention all fall within the protection scope of the claims of the present invention.
