る。In the case of the waterproof structure shown in FIG. 15 or the waterproof structure in which the joint 15 is filled with a caulking material, if a building is deformed due to an earthquake or ground change, the deformation is caused by this deformation. It is difficult for the waterproof structure or the caulking material to follow the dimensional change of the joint 15, which causes a crack or a gap. For this reason, there was a problem that the waterproof function became incomplete and water leaked. As one means for solving this problem, there is a means for fitting a retrofitted outer wall into a portion where the joint 15 is formed, suppressing deformation of the joint 15 and maintaining a waterproof effect. However, in this case, water leakage occurs unless the waterproofing around the joints reinforced and covered by the retrofitted outer wall or the retrofitted outer wall is completed.

In addition, since the deformation is prevented by the retrofitted outer wall, water leakage from around the joint is almost completely prevented. 2) According to the waterproof structure around the outer wall joint having the retrofitted outer wall according to claim 2 of the present invention, the draining sheet is made of CPP.
And butyl rubber, etc., which improve dimensional stability and durability, improve sealing performance, and provide almost perfect waterproofing for a long period of time. 3) According to the waterproof structure around the outer wall joint having the retrofitted outer wall according to the third aspect of the present invention, the upper surface side of the pillar portion that is likely to leak water is sealed by the superposed structure of the draining sheet, so that water leaks from this portion. Is more completely prevented. 4) According to the waterproof structure around the outer wall joint having the retrofitted outer wall according to claim 4 of the present invention, since the retrofitted outer wall is positioned by the cap-shaped drainer sheet, it is reliably held at a predetermined position.
