る。2. Description of the Related Art It is known that a waterproof sheet made of a vinyl chloride resin is fixed on a rooftop of a building to provide waterproofing. Such waterproofing methods include a so-called contact method and an insulating method. Among these, the contacting method is a method in which a bonding agent is applied to the under ground of a building, whereby the waterproof sheet and the ground surface are brought into close contact and joined. However, in this method,
The operation of applying and drying the bonding agent is very troublesome, and a large amount of solvent evaporates during drying, thus deteriorating the working environment.

を示す正面図である。On the other hand, in the insulation method, the entire surface of the waterproof sheet is not joined to the base, but a fixing member is provided at a key point on the base. This fixing member is provided with a coating layer of vinyl chloride resin on the surface of a steel plate. And
This steel plate is fixed to the base surface with an anchor or the like, and the coating layer of the fixing tool is solvent-welded or heat-fused to the waterproof sheet. This method is excellent in terms of workability,
It is a construction method with high waterproof performance. FIG. 4 is a front view showing a state in which a vinyl chloride resin sheet has been applied to a corner of a building by an insulating method.

The fixing member 6 is preferably composed of a steel plate made of a galvanium steel plate and a coating layer of a vinyl chloride resin covering at least a main surface of the steel plate. The fixing member 6 is for a corner, and has a substantially L-shape as a whole. The fixing member for the flat part is substantially flat.
The horizontal part 6a of the fixing member 6 is brought into contact with the flat part 1a,
The vertical portion 6 b is brought into contact with the vertical wall surface 1 c, and the fixing member 6 is installed at the corner 10. At this time, the corner between the horizontal part and the vertical part of the fixing member 6 is set along the corner line 1b. The fixing member 6 is fixed to the flat part 1a by a fixing device 4 such as an anchor.

The two are joined. Next, the wall surface 1c is covered with the main body portion 15a of the vinyl chloride resin sheet 15, and the end 15b of the vinyl chloride resin sheet 15 is joined to the vertical portion 6b of the fixing member 6, and at the same time, the end 15b is connected to the vinyl chloride resin sheet. 12 are mounted on the end 12b, and both are joined. In this state, each end 12b, 15 of the vinyl chloride resin sheets 12 and 15
b are superimposed on the horizontal portion 6a. Next, a liquid sealing material is caused to flow at a boundary between the end portion 15b and the vinyl chloride resin sheet 12, and the liquid sealing material is cured to form the sealing material layer 3.

に覆われており、固定部材６の露出部分が小さく、かつ
その露出部分の形状も、非常に細長い形状である。However, as a result of further study of this insulation method by the present inventor, they have found the following problem. That is, the operation of placing the vinyl chloride resin sheet 12 on the horizontal portion 6a and joining the two is relatively easy because the joining area is large. However, when joining the end portion 15b of the vinyl chloride resin sheet 15 on the wall surface 1c at the corner to the vertical portion 6b of the fixing member 6, most of the fixing member 6 has already been used. , The exposed portion of the fixing member 6 is small, and the shape of the exposed portion is also very elongated.

り、施工能率が悪かった。Therefore, even if the end portion 15b is fused to the exposed portion of the fixing member 6 by heat or is welded by using a solvent, the vinyl chloride resin is preferably applied to such a narrow and elongated region. The work of fusing or fusing the sheet 15 is actually difficult to perform, requires a very high level of skill, requires a long working time, and has a poor working efficiency.

る。In particular, in the joining area 16 between the vinyl chloride resin sheet 15 and the fixing member 6, the joining area is small,
Further, since the joining portion is elongated, the joining strength tends to be insufficient, and the joining portion 1 of the vinyl chloride resin sheet 15 is partially formed.
7 could rise from the fixing member 6 and required repair. If such a phenomenon occurs, the appearance of the construction site is impaired, and the waterproof performance is adversely affected.

を被覆することを特徴とする。According to the waterproofing method of the present invention, in order to waterproof a wall surface of a building and a flat field portion, the waterproofing method is carried out through a fixing member at a corner where the wall surface contacts the flat field portion via a fixing member. When constructing a vinyl resin sheet, the fixing member is made of a steel plate having a vertical portion and a horizontal portion, the surface of which is covered with a vinyl chloride resin, and the vinyl chloride resin sheet covers one of the vinyl chloride resin sheets and It consists of the other vinyl chloride resin sheet covering the flat area,
Bonding the one vinyl chloride resin sheet to the fixing member in advance and covering at least the vertical portion with the one vinyl chloride resin sheet and covering the wall surface with the one vinyl chloride resin sheet; Leave the wall covering portion, then fix the fixing member to the corner, cover the wall with the wall covering portion, and attach the end of the other vinyl chloride resin sheet to the one vinyl chloride resin sheet. The horizontal portion and the flat portion are covered with the other vinyl chloride resin sheet.

After coating, the fixing member is fixed to the corner, and the end of the other vinyl chloride resin sheet is joined to one vinyl chloride resin sheet. That is, since one of the vinyl chloride resin sheets is previously bonded to the vertical portion of the fixing member, if the fixing member is installed at the corner and fixed, the vinyl chloride resin sheet is now formed. Is securely fixed to the vertical portion of the fixing member, and the vinyl chloride resin sheet does not float. At this stage, the fixing of the vinyl chloride resin sheet has been completed, so that the step of positioning the vinyl chloride resin sheet again with respect to the fixing member on site, and joining and fixing the sheet becomes unnecessary.

きる。Therefore, in the waterproofing method at the corners of the building, the vinyl chloride resin sheet can be easily applied, the construction state does not deteriorate, and the construction efficiency can be improved. In addition, since the polyvinyl chloride resin sheet and the fixing member are pre-joined, and there is no need to perform difficult joining work on site, it is possible to prevent the occurrence of poor joining between the polyvinyl chloride resin sheet and the fixing member, It is possible to prevent the resin sheet from floating around the corner.
