Building masonry wall self preservation temperature bridge cut -off combination building block

Building masonry wall self preservation temperature bridge cut -off combination building block belongs to the design and manufacture technical field of building block. The terminal surface upper band has the zigzag boss around the body, has the dovetail between the zigzag boss. The intermediate part of building block has the insulation material chamber. The utility model discloses a formed by building block monomer combination, building block two inboard dovetails are geared to the needs of the job mutually and form the concrete and pour into the chamber when building by laying bricks or stones, make dabbling concrete and dovetail be tenon shape and combine, make two building block combination meetings more firm, improve the building quality. The dovetail in the outside utilizes to combine with the tenon shape of wall ash, and it is more firm to grab the ash, has prevented that subsequent wall skin problem that drops from taking place. In addition, the cold bridge of perps of building block can be blockked up in building block dislocation half block building block about when building by laying bricks or stones, and the cold bridge of the flush joint that can block up the building block is built by laying bricks or stones in upper and lower building block dislocation, has improved the heat preservation effect greatly. The utility model discloses simple structure, reasonable in design. The problem of current building block exist is solved.
