Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction tools, in particular to a shear wall screw hole plugging tool. BACKGROUND

[0002] The shear wall, also known as the anti-seismic wall, is a wall that mainly bears the horizontal load and vertical load caused by wind load or earthquake action in a house or structure to prevent shear failure of the structure. The shear wall is usually cast using a mold, and the mold is fixed using a screw. When the mold is removed later, the screw is also removed, thus leaving a screw hole on the shear wall. If the screw hole is not tightly plugged, the probability of wall leakage will be greatly increased.

[0003] The existing plugging method for the screw hole usually requires inserting a hole plug into the screw hole of the outer wall first, and then pouring cement mortar into the screw hole. If the hole plug is not inserted into the screw hole and the cement mortar is directly poured, the cement mortar will overflow from the screw hole. The existing hole plug installation is usually performed manually by workers. If the workers are negligent, the hole plug may not be installed in some screw holes. The workers need to frequently move on the outer wall during the installation of the hole plug, and the installation of the hole plug has a high risk coefficient. Moreover, the risk coefficient of the installation of the hole plug increases with the increase of the floor.
