Problems solved by technology
After the construction of the project is completed, there will be a wide range of grout leakage in these holes. Whether it is the quality of the concrete after the demolition of the formwork or the later repair of the plug holes, the quality and perception of the effect are very poor.
At present, the solution for the inner and outer wall holes during construction in this field is basically to add rubber rings on both sides of the pull screw to seal the outer wall, and the inner wall is only reinforced with formwork for the tie rods, basically without any anti-leakage measures.

The invention discloses a plugging device for the hole of the template through the wall of the anti-tension screw, which comprises a stretchable elastic sponge stop layer sleeved on the anti-tie screw, which is set on the outer side of the stretch elastic sponge stop layer for fixing it on the anti-tie The collar on the screw rod, and the side-drawing screw nuts located outside the collar and sleeved on the side-drawing screw, wherein the collar is an openable and closable structure. The formwork wall-penetrating plugging device for the hole of the pulling screw proposed by the invention ensures the construction quality at the hole of the inner and outer walls.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a plugging device and an operation method for a hole of a formwork penetrating a drawing screw through a wall. Background technique [0002] During the construction of concrete shear wall columns or frame structures, the size of the tie rod holes left on the outer wall is basically the same. In order to prevent water seepage, rubber rings are generally used to seal the tie rod holes on both sides of the formwork. However, the rubber ring is generally not provided on the parts of the inner wall that do not involve water seepage. After the construction of the project is completed, there will be a wide range of grout leakage at these holes. Whether it is the quality of the concrete after the demolition of the formwork or the later repair of the plug holes, the quality and perception of the effect are very poor. At present, the solution for the inner and outer wall hol...
