Abstract

The utility model relates to the technical field of wall repair, in particular to an old community wall inner side repair structure, which comprises an outer wall, wherein an inner wall is arranged on the side edge of the outer wall, and a repair structure is arranged at the corner of the inner wall and the outer wall. The inner side repair structure of the old community wall body gradually reduces heat loss of a heat bridge part along with the increase of the thickness of the heat insulation mortar layer, the heat insulation performance of the wall body is better, the reduction range is reduced along with the increase, the thickness range of the heat insulation mortar layer is 20-50 mm, the thickness of the heat insulation mortar layer of the inner wall is considered to have larger influence on indoor use space and attractiveness, therefore, the economy and practicality are comprehensively considered, the thickness of the heat insulation mortar layer is preferably 20mm, compared with an outer wall structure without the heat insulation mortar layer coated along the inner wall, the heat loss effect of the heat bridge part can be reduced by coating the heat insulation mortar layer, the heat loss can be reduced by adding heat insulation measures of the heat insulation mortar layer at the heat bridge part, the whole heat insulation performance of the outer wall is poorer, and the effect of the heat bridge heat insulation measures is increased more obviously.
