TECHNICAL FIELD

[0001] The utility model relates to new wall body anti -cracking technical field, concretely relates to a plant tendon structure of reducing wall body cracking. BACKGROUND

[0002] There are many reasons for the cracks between new and old wall bodies, mainly including humidity difference, material difference, external factors and improper construction, and the humidity of new wall and old wall is often unbalanced. The old wall has a relatively high dryness because of a long time, and the new wall is relatively wet and needs a period of time to evaporate the moisture in the wall. In this process, the volume of the new wall will shrink slightly, resulting in cracks at the joint between the new and old walls. The traditional process of laying a hanging net between the new and old wall bodies can effectively reduce the generation of cracks, but the hanging net is easy to move during the fixed laying process, and another person is needed to assist in fixing the hanging net. The construction of the hanging net needs to be improved. The new wall and the old wall body have no intermediate bridge for fastening connection, and there is tensile stress between the new wall and the old wall body, which also easily leads to wall cracking. Therefore, we propose a plant tendon structure for reducing wall cracking. SUMMARY
