る。[Detailed description of the invention] The present invention relates to a waterproof sheet with curing tape that prevents contamination of the adhesive part of the waterproof sheet when adhering vulcanized synthetic rubber waterproof sheets to each other. A curing tape with adhesive parts on at least both ends of the strip is pasted on the joints of vulcanized synthetic rubber waterproof sheets used for water shielding of treatment ponds, irrigation canals, rivers, etc., and muddy water, earth and sand are removed from the joints of the waterproof sheets. This invention relates to a curing tape-added sulfurized synthetic rubber waterproof sheet that prevents contamination.

は、主としてコンクリート、アスフアルトが一般

た。 Traditionally, concrete and asphalt have been commonly used as water-shielding lining materials for reservoirs, etc., but recently concrete and asphalt have become more susceptible to large amounts of strain.
Vulcanized rubber sheets have come to be widely used because they have good weather resistance and can follow the movement of the substrate.

ているのが実状である。 However, due to the manufacturing technology of vulcanized rubber sheets, there are dimensional restrictions on the manufacturing equipment, and although the length may be long (about 200 m), the width is at most 6 to 10 m. It is. Therefore, in reality, such vulcanized rubber sheets are transported to the site where they are to be constructed, and the vulcanized rubber sheets are joined together at the site.

The bonded portion may peel due to a decrease in adhesive strength, and the water-blocking function will no longer be achieved.

があつて可成りの時間、手間を要していた。 Therefore, in order to improve this problem, we perform buffing and washing with water, but in the case of buffing, it is necessary to secure a power source for the buffing machine, and since the base is unstable, using a buffing machine will damage the sheet. It gets stuck. If there is no power source, it is necessary to rely on the input and it is difficult to buff to a uniform thickness. When washing with water, it is necessary to let it air dry or wipe it with a cloth, which takes a considerable amount of time and effort.

合成ゴム系防水シートにある。 The present invention was devised to improve these points by keeping in mind the current situation as described above, and aims to prevent contamination by pre-coating the joint parts of the waterproof sheet with a synthetic resin film. The feature is that a thin curing tape having adhesive parts on both ends of the strip in the longitudinal direction and in a direction perpendicular to the longitudinal direction at appropriate intervals is pasted to the joint part of the vulcanized synthetic rubber waterproof sheet. A curing tape-added sulfurized synthetic rubber waterproof sheet is constructed to prevent contamination of the joint portion of the waterproof sheet.
以下、本考案の具体的実施態様を添付図面を参
照しつつ説明する。 Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.
第１図は本考案防水シートの一例を示し、図中
１，１は互いに接合する加硫ゴムシートからなる

この場合、養生テープ３は加硫ゴムシート１の裏

硫ゴムシートの側面４をも被覆する。 Fig. 1 shows an example of the waterproof sheet of the present invention. In the figure, 1 and 1 are waterproof sheets made of vulcanized rubber sheets that are joined to each other. A curing tape 3 is attached to the joint part 2 near the end of the vulcanized rubber sheets. It's pasted.
In this case, the curing tape 3 is bent and pasted from the back side of the vulcanized rubber sheet 1 to the front side, or in the case of one vulcanized rubber sheet 1', from the front side to the back side. Cover.
このようにすれば、加硫ゴムシート１の接合部

効である。 In this way, it is possible to prevent contamination of the joint portion 2 of the vulcanized rubber sheet 1 and the exposed side surface 4 during joining.In particular, prevention of contamination of the side surface 4 is effective, for example, at the stepped portion when joining a waterproof sheet. This is effective because the side surfaces serve as adhesive surfaces when a reinforcing sheet is pasted on top.

As shown in the figure, adhesive portions 6 are provided at regular intervals at both ends of the strip 5 in the longitudinal direction (indicated by arrows) and in a direction perpendicular to the longitudinal direction. In this case, the strip 5 must be able to conform to the vulcanized rubber sheet, be able to follow the expansion and contraction of the vulcanized rubber sheet, be able to withstand trauma when the vulcanized rubber sheet is laid, such as drag resistance, that is, not tear, and be vulcanized. When joining rubber sheets, it is necessary to meet requirements such as being able to be removed without resistance and not absorbing moisture. Materials suitable for this purpose include polyethylene, nylon, polypropylene, polyvinyl chloride, etc. with a thickness of approximately 60μ. Synthetic polymer films, rubber friction woven fabrics, non-woven fabrics, etc. may be mentioned.
また、粘着部６は両面粘着テープあるいは粘着

程度で十分である。 The curing tape 3 also has an adhesive part 6 in a direction perpendicular to the tape's longitudinal direction, which prevents mud from flowing to other parts even if one part of the curing tape breaks and muddy water enters. This is to prevent it. However, this type of curing tape is only temporarily attached to the joints of waterproof sheets, and its adhesive strength is 1.0Kg/25mm.
It is enough.

設けたり、接着剤を塗布しない。 The vulcanized synthetic rubber waterproof sheet used in the present invention is preferably one with excellent weather resistance, such as one made of ethylene-propylene, terpolymer (EPT), butyl rubber (IIR), or a blend of EPT and IIR. Blends of vinyl chloride and nitrile rubber or chlorinated polyethylene are also used. Before pasting the curing tape, usually no adhesive tape or adhesive is applied to the joints of the tarpaulin sheets.

It has a structure. In this case, the sheet 9 is preferably provided with at least adhesive portions on both sides of the strip.

とができる効果をも有している。 As described above, the curing tape-added sulfurized synthetic rubber waterproof sheet of the present invention has a joint part of the waterproof sheet,
That is, in the area where the adhesive is applied or the adhesive tape is interposed, a curing tape with adhesive parts provided at both longitudinal ends of a strip such as a synthetic resin film and at appropriate intervals in a direction perpendicular to the longitudinal direction is applied. This tape is pasted together, and can effectively prevent contamination by earth, sand, muddy water, etc. at the joint, and even if a part of the curing tape is damaged, the earth, sand, etc. can be applied in the longitudinal direction and at right angles to the damaged area. It has the effect of preventing contamination by only penetrating into one area surrounded by the adhesive part in the direction, and since it is not fully adhesive, it can be removed without much resistance when the curing tape is attached to the sheet. It also has the effect of being easily removed.

傷に耐えることができる優れた実効もある。 Furthermore, due to the above-mentioned effects, the curing tape-added sulfurized synthetic rubber waterproof sheet of the present invention omits the washing and buffing work of the joints at the construction site, which was indispensable when bonding conventional synthetic rubber waterproof sheets. The waterproof sheets can be completely pre-adhesively treated by simply peeling off the waterproof sheets, and have the excellent effect of ensuring sufficient adhesion between the waterproof sheets to withstand damage during installation.
