The present invention is intended to solve the above-described problems, and an object of the present invention is to provide a waterproof treatment method that can completely prevent water leakage in the outer wall through piping construction of an existing structure.
Therefore, the invention of claim 1 is the waterproof processing method of the outer wall through piping construction in which the outer wall of the existing structure is cored and the piping is passed through the cored portion.
An outer wall portion that has been slightly cored on the outer surface side of the outer wall of the cored portion, and a tubular member in which a draining collar has been formed on the entire outer surface of the predetermined portion is inserted into the cored portion to perform a larger core. After fixing the flange to the pipe, the pipe is penetrated through the tubular member, and waterproof treatment is performed between the tubular member and the outer wall, and between the tubular member and the pipe.
The invention according to claim 2 is characterized in that the draining collar is welded to the entire circumference of the outer surface of the tubular member to form a bolt hole for fixing to the outer wall.
The invention of claim 3 is characterized in that a waterproof sealant is filled around the outer wall and the tubular member, the brim portion is caulked, a spacer is filled in the gap between the tubular member and the pipe, and the waterproof treatment is performed.
The invention of claim 4 is further characterized in that a root-rolled concrete is placed so as to cover a tubular member protruding to the outer surface of the outer wall, and a waterproof treatment is performed between the root-wrapped concrete and the outer wall.
本発明は、既存構造物の外壁をコア抜きし、コア抜き部に配管を通す外壁貫通配管工事の防水処理方法において、前記コア抜き部の外壁外面側に一回り大きいコア抜きを行い、所定箇所外面全周に水切り用ツバを形成した管状部材を前記コア抜き部に挿入して一回り大きいコア抜きを行った外壁部に前記ツバを固定した後、管状部材を通して配管を貫通させ、管状部材と外壁との間、管状部材と配管との間に防水処理を施したので、地下室などの場合であっても水等の浸入を防止することが可能となる。 The present invention relates to a waterproofing method of an outer wall through pipe construction in which an outer wall of an existing structure is cored and a pipe is passed through the cored part, and the cored part is slightly larger on the outer wall outer surface side of the cored part. After inserting a tubular member having draining collars on the entire outer surface into the cored part and fixing the collar to the outer wall part that has been cored slightly larger, pipe is passed through the tubular member, Since waterproofing is performed between the outer wall and between the tubular member and the piping, it is possible to prevent water and the like from entering even in the case of a basement or the like.
