【発明の詳細な説明】DETAILED DESCRIPTION OF THE INVENTION

【０００１】[0001]

【産業上の利用分野】本発明は、構造物の防水構造のう

風による吸引力に対して強固にできる防水シートの固定
構造及びその固定方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for waterproofing a structure by means of mechanical fixing means, and more particularly, to a structure for fixing a waterproof sheet which can make the waterproof sheet strong against suction force by wind and the fixing thereof. Regarding the method.

【０００２】[0002]

【従来の技術】従来、機械的固定手段による防水シート
固定構造の固定手順は次のようなものが一般的であっ
た。2. Description of the Related Art Conventionally, the fixing procedure of a waterproof sheet fixing structure using mechanical fixing means has been generally as follows.

【０００３】それは、一定の幅を有するロール状に巻か
れた防水シートを屋上床などの被防水体の表面上に展開
した後、その一方の長縁から数十mmの所を長縁に沿って
ビスや釘など下地に応じて適宜選択したファスナーで一
定間隔に留付ける。It is a method in which a roll-shaped waterproof sheet having a certain width is spread on the surface of an article to be waterproofed, such as a rooftop floor, and then several tens of millimeters from one of the long edges extends along the long edge. Fasteners such as screws and nails are fixed at regular intervals with fasteners that are selected according to the substrate.

【０００４】次いで、他の防水シートを先に固定した防
水シートの固定側に１００mm程度重なるように展開し、
この重なり部分のうち重合箇所の上部側防水シートの端
縁に近い側を熱風にて熱融着する。Then, the other waterproof sheet is developed so as to overlap the fixed side of the waterproof sheet previously fixed by about 100 mm,
Of the overlapping portion, the side close to the edge of the upper waterproof sheet at the overlapping portion is heat-sealed with hot air.

【０００５】上記作業を順次繰り返して防水性を有する

シートの一縁は全長に亘りファスナーで一定のピッチで

両端縁が下地に固定されることになり、防水シートは風
などによって飛ばされないように構成されている。The above work is repeated in sequence to construct a waterproof roof, wall, or other enclosure. In this way, one edge of the waterproof sheet is fastened to the base of the article to be waterproofed with a fastener at a constant pitch over the entire length, and the other edge is fixed to the previously fastened waterproof sheet. Since both edges of the waterproof sheet are fixed to the base, the waterproof sheet is configured not to be blown off by wind or the like.

【０００６】[0006]

【発明が解決しようとする課題】しかるに、図８に示す
ように、このように防水シートａの両端縁を留付けられ
た後に、該防水シートａに風の負圧による吸引力が作用
すると、防水シートａの中央部は上方に膨らんで防水シ

の固着部を引き剥がすような働きをすると共に、左右の
防水シートａ，ａの面内引張力の合力がファスナーを引
き抜くような作用をし、強風の場合には防水シートａが
下地より剥がれることになる。However, as shown in FIG. 8, when the suction force due to the negative pressure of the wind acts on the waterproof sheet a after the both edges of the waterproof sheet a are fastened as described above, The central portion of the waterproof sheet a swells upward to generate an in-plane tensile force on the waterproof sheet a, and this tensile force acts to peel off the fixed portion at the overlapped portion, and the left and right waterproof sheets a, a The resultant force of the in-plane tensile force acts to pull out the fastener, and in the case of strong wind, the waterproof sheet a is peeled off from the base.

【０００７】従って、この場合に構成材料に必要な強度
特性としては、風によって起こる面内引張力によって
防水シートが破れないこと、防水シートの融着部が引
き剥がされないこと、ファスナーが引き抜かれず、フ
ァスナー部近傍の防水シートがち切れないこと、などが
挙げられる。Therefore, in this case, the strength characteristics required for the constituent materials are that the waterproof sheet is not broken by the in-plane tensile force generated by the wind, the fused portion of the waterproof sheet is not peeled off, the fastener is not pulled out, For example, the waterproof sheet near the fastener part may not be cut off.

【０００８】これらの耐力を向上させるには、は防水
シートに補強繊維を入れることにより、はファスナー
間隔を小さくすることなどにより可能であるが、は防
水シートの接合を融着によっている場合はすでに耐力の
上限であるから耐力値そのものを増大させることは不可
能である。（引き剥がしの場合は端から順に剥がれてい
くので、融着幅を広くするなどの対策は無効である。）To improve the proof stress, it is possible to insert reinforcing fibers into the waterproof sheet, reduce the fastener interval, and the like. Since it is the upper limit of yield strength, it is impossible to increase the yield strength itself. (In the case of peeling, since it peels off in order from the edge, measures such as widening the fusion width are invalid.)

【０００９】そこで、の耐力が不足する場合には防水
シート幅を狭くすることによって面内応力を小さくして
やる必要がある。Therefore, when the proof stress is insufficient, it is necessary to reduce the in-plane stress by narrowing the width of the waterproof sheet.

【００１０】しかし、そうするとファスナー固定の列数
も融着の列数も増えてしまうので工事のコストが非常に
高くなる欠点があった。However, in that case, the number of rows for fixing the fasteners and the number of rows for the fusion bonding increase, so that there is a drawback that the construction cost becomes very high.

題を解決したものである。Therefore, as a result of intensive studies, the inventors of the present invention have found that, as a result of the invention, a plurality of fasteners are appropriately provided along the edge of a waterproof sheet having a predetermined width. Are fastened in a line in a row at the interval of, and the waterproof sheet is fixed on the base portion, the edge of the waterproof sheet adjacent to the edge of the waterproof sheet is overlapped, and the row of fastener fixing points in the row is straddled. In this way, both polymerization points are pasted with an adhesive to form a fixing structure for a waterproof sheet having an inner joint portion and an outer joint portion, or on the edge of a waterproof sheet having a fusion resistance of a predetermined width. Along the line, fasten a plurality of fasteners in a row at appropriate predetermined intervals, fix the waterproof sheet on the base, then superimpose the edges of the adjacent waterproof sheet on it, and flatten it by the superposed location. -Shaped two inner hot air outlets and outer heat Insert the air outlet across the one row of fastener rows, and move the inner hot air outlets ahead of the outer hot air outlets to obtain hot air from the inner hot air outlets and the outer hot air outlets. By melting both polymerization points across the row, heat-bonding both polymerization points by pressure bonding immediately after this, by using both of these points as an inner joint part and an outer joint part by the method of fixing the waterproof sheet. , For example, even if the peeling action works, the force is applied to the inner joint part of the two places, but since it acts as shear stress, it can be made extremely strong, and the above-mentioned problems were solved. It is a thing.
