Abstract

PURPOSE:To reduce field waterproofing execution in constructing a balcony large enough to stretch over two building units. CONSTITUTION:At the time of carrying out the waterproofing execution of a balcony, each of waterproof plates 40 is set up on each top face of two bedding materials 20 constituting each balcony of two balcony units A and B to be connected as adjoined with each other at the stage of unit manufacturing, and these waterproof plates 40 are attached tight to the bedding materials 20 excepting the vicinity of a connected part S between these units themselves, manufacturing the units A and B. Next, when these units A and B are connected at a construction site, a drainage ditch member 30 housed with a fitting holding member 60 is inset in a recess 25 in a gap with the bedding material 20 formed in the connected part S in a state that a nonsticking part of the waterproof plate 40 in and around the connecting part S is turned upward. In succession, after this insetting, the waterproof plates 40 of both units A and B are restored to its original form, and a joint 41 to be formed in space between both the waterproof plates 40 and 40 is closed by a joint material 70 from the upside of the waterproof plate 40, while a tip of the joint material 70 is fitted in a fitting holding member 60 in the drainage groove member 30 and locked tight.

ができる。Next, as shown in FIG. 3B, the waterproof material 40 that has been turned up is returned to its original state. A joint extending in the left-right direction between the end of the waterproof plate 40 on the balcony unit A side and the end of the waterproof plate 40 on the balcony unit B side (this joint is a joint on the joint between the balcony units). 41), the fitting recess 61 of the fitting holding member 60 is aligned, and in that state, the joint 41 of the waterproof plate 40 is closed with the joint material 70, and the fitting protrusion 71 on the lower surface of the joint material 70 is fitted. The fitting holding member 60 is fitted and fixed in the fitting concave portion 61. Thereby, the joint 41 of the waterproof plate 40 can be sealed.

Before the sealing of 1, joints extending in the front-rear direction (joints between the waterproof plates 40, 40 in each balcony unit A, B) 4
2 is sealed first. The sealing of the joint 42 extending in the front-rear direction is similar to that of the joint 41 extending in the left-right direction.
The joint 42 extending in the front-rear direction is prioritized over the joint 41 extending in the left-right direction. That is, by connecting the two balcony units A and B, the joints 42 extending in the front-rear direction of the two balcony units A and B are linearly continuous, but the joints 4 extending in the front-rear direction.
The joint 42 extending in the front-rear direction is closed by using the joint material 70 having a length that straddles both units A and B so as to continuously close the two. Then, the joint 41 extending in the left-right direction is sealed.

できる。In this way, waterproofing is performed as much as possible in advance at the stage of manufacturing the balcony unit (the waterproof plate 40 is stretched and the drain groove member 30 is fitted under the joint 42 extending in the front-rear direction). As a result, it is possible to significantly reduce the number of waterproof construction work in the field and shorten the construction period. Further, since the waterproof plate 40 is incorporated in the balcony units A and B in advance, it is not necessary to separately transport a long waterproof plate, and the transport cost can be reduced.
