Through above-mentioned technical scheme, the strengthening layer solidifies the back, and it is fixed with the support column to predetermine the bar planting.
Furthermore, both ends of the preset embedded steel bars extend into the newly added base layer.
Through above-mentioned technical scheme, further strengthen the joint strength between support column bottom and the raft board basic unit.
Further, the side face of the supporting column is provided with a groove face.
Through above-mentioned technical scheme, increase the area between support column lateral wall and the strengthening layer to improve the joint strength between support column and the strengthening layer.
Further, predetermine the bar planting with the connecting reinforcement is the reinforcing bar of the same model.
Through the technical scheme, the manufacturing and construction are convenient.
Further, the support column is vertically arranged on one side of the raft foundation layer.
Through above-mentioned technical scheme, be convenient for raft foundation layer provides the support for the support column steadily.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the preset embedded steel bars are fixed with the connecting steel bars, so that the connecting strength between the end part of the support column and the newly-added base layer is enhanced, and the connecting strength between the bottom end of the support column and the raft base layer is improved;
(2) furthermore, a newly-added base layer is formed by pouring on the raft base layer again, so that the structural strength of the original raft base layer of the old building and the flatness of the upper surface of the original raft base layer are improved;
(3) further, form the strengthening layer through pouring on support column week side, when improving support column bearing strength, be used for fixing predetermineeing the bar planting with the support column.
