Description
Technical Field
The invention relates to the technical field of building construction, in particular to a post-pouring construction method for a toilet shear wall.
Background
Underground waterproofing, roof waterproofing and toilet waterproofing are the key points for controlling the construction quality of buildings, particularly for toilet waterproofing, once hidden dangers occur, the use function of the toilet can be influenced, great inconvenience is caused to life, and neighborhood harmony can be influenced.
Because the wall body is usually constructed and constructed after the ground structural layer is finished, a gap usually exists at the joint of the wall body and the ground, and after the house is constructed, a small crack is formed at the joint of part of the wall body and the ground due to shrinkage deformation, so that the hidden danger of water leakage is caused. In addition, when the waterproof paint is coated on a wall, the paint on the wall surface falls down due to the action of gravity and is accumulated at the corner, and once the accumulated paint is too much, the drying speed of the paint is influenced, and cracks can be generated. Therefore, the joint of the existing toilet wall and the ground is usually subjected to arc-smearing treatment, namely, the joint of the existing toilet wall and the ground is smeared into an arc shape, so that the phenomenon that coating is accumulated at a corner and is dried and cracked is avoided, and the waterproof performance is improved. However, the existing arc-wiping treatment is usually carried out independently after the wall body and the ground are finished, and the arc-wiping treatment cannot avoid cracks formed by shrinkage deformation of the wall body and the ground, so that potential water leakage hidden danger still exists.
