Self-insulation bridge-cutoff core foam concrete block

The utility model relates to exterior wall tiles for building engineering, in particular to a self-insulation bridge-cutoff core foam concrete block, which comprises a hollow cylindrical composite concrete outer casing with two bottomless pass-through ends and cement fly-ash foams filled inside a cylindrical cavity. The block is in the shape of a rectangle and includes length edges, width edges and height edges, an insulating plate is inlaid on the bottom surface of the length edges and width edges of the outer casing along the length edge direction, and another insulating plate is inlaid on the left lateral surface and/or the right lateral surface of the width edges and the height edges of the outer casing along the height edge direction. The self-insulation bridge-cutoff core foam concrete block can eliminate severe heat loss caused by block building grey cast penetrating through straight slits in the prior art, has fine heat insulation effect, is low in cost, long in service life and high in effect of savi
