Because the broken bridge connecting piece 4 of encorbelmenting is fixed to be set up in stand subassembly below, and it carries out fixed connection with stand subassembly and beam assembly respectively, stand subassembly and beam assembly at this place need bear bigger load, so need improve the support bearing capacity of the broken bridge connecting piece 4 of encorbelmenting, support two sets of fourth joint pieces 402 through two sets of parallel arrangement's fourth backup pad 403 and fixed a plurality of groups ' division boards 404 that set up between two sets of backup pads, furthest's improvement encorbelments the whole intensity of broken bridge connecting piece 4. Simultaneously at the bottom of the outside of inner bottom plate 406, angle steel mounting groove 407 has been seted up to fixedly connected with fourth fixed plate 410 here, installs angle steel 601 in angle steel mounting groove 407, prevents that the angle steel from protruding out, influences the wholeness of assembled composite wall.

A fourth arc-shaped mounting groove 409 is formed in the outer side of the inner bottom plate 406 of the C-shaped plate 405, and the C-shaped plate 405 and the C-shaped steel 501 are fixedly connected through screws. A fourth bridge opening 411 is formed on the fourth supporting plate 403 and the isolation plate 404. The plurality of sets of the isolation plates 404 are parallel to each other, and the isolation plates 404 are parallel to the fourth fixing plate 410. By providing the fourth bridge opening 411 on the fourth support plate 403 and the isolation plate 404, energy transfer generated by a thermal bridge is reduced, and thermal loss is reduced.

The bottom surfaces of the fourth supporting block and the two groups of fourth clamping blocks are located on the same horizontal plane, the heights of the two groups of fourth clamping blocks are different, the upper top surfaces of the relatively low group of fourth clamping blocks and the upper top surfaces of the fourth supporting block are located on the same inclined plane, the size of the fourth supporting block is reduced, and the connection strength of the cantilever broken bridge connecting piece is guaranteed not to be suddenly reduced while the heat loss generated by a heat bridge is reduced.
