本発明は加硫ゴムシート同志又は加硫ゴムシートと熱可
塑性エラストマーシートを接着する防水シートの接合方
法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof sheet joining method for adhering vulcanized rubber sheets together or a vulcanized rubber sheet and a thermoplastic elastomer sheet.
従来、貯水池などの遮水用ライニング材としては、主と
してコンクリートアスファルトが一般に使用されてきた
が、最近では歪量が大きく、耐候性がよく、そして下地
の動きに追従できるものとして加硫ゴムシートが巾広く
使用されるようになった。Traditionally, concrete asphalt has been mainly used as a water-shielding lining material for reservoirs, etc., but recently vulcanized rubber sheets have been used as a material with a large amount of strain, good weather resistance, and the ability to follow the movement of the substrate. It has become widely used.
しかしながら、加硫ゴムシートの製造技術からして、製
造設備に寸法上の規制があり、長さの方は長尺可能（２
００ｍ）程度であっても、幅の方は６〜１０程度である
。 従って、このような加硫ゴムシートを施工現場まで
運搬し、現場において加硫ゴムシート同志を接合してい
た。However, due to the manufacturing technology of vulcanized rubber sheets, there are dimensional restrictions on the manufacturing equipment, and the length can be longer (2.
Even if it is about 00 m), the width is about 6 to 10 m. Therefore, such vulcanized rubber sheets were transported to the construction site, and the vulcanized rubber sheets were joined together at the construction site.
ところが、この接合部の漏水防止処理に関しては、従来
から種々の方法があるがこれと言った決め手がなく、接
着剤による方法、未加硫ゴムを使用する方法が主に採用
されている。However, although there have been various methods for preventing water leakage at the joint, there is no definitive method, and methods using adhesives and methods using unvulcanized rubber are mainly employed.
接着剤を使用する方法は、塗布むらができ均一な皮膜が
できないため接着不均一になり、またオープンタイムの
取り方により接着力の変化が大きく、更に決定的な欠点
としては材料がいくらよくても施工者の能力によって接
着状態が大きく左右されるため目標とする接着力そして
遮水機能を保証することは非常に困難である。Methods using adhesives result in uneven adhesion, as a uniform film cannot be formed, and the adhesive strength varies greatly depending on how the open time is taken.Another decisive drawback is that the material may not be as good as it is. However, it is extremely difficult to guarantee the desired adhesion strength and water-shielding function, as the adhesion condition is greatly influenced by the ability of the installer.
また、未加硫ゴムテープを使用する場合では。Also, when using unvulcanized rubber tape.

There is a method of spot curing by heating to 200°C and applying pressure of ioo to 150 kg/cJ (see Japanese Patent Publication No. 53-5459), but in this case it is necessary to bring a vulcanizer to the construction site, and the high temperature Unless the adhesive is vulcanized at high pressure, the target adhesive force cannot be obtained, and furthermore, it takes a lot of time and is inefficient.

ートの接合において、加硫ゴムシートとしてエチレン。The present invention aims to improve these points, and its purpose is to increase work efficiency, increase the adhesion between vulcanized rubber sheets or between vulcanized rubber sheets and thermoplastic elastomer sheets, and achieve adhesion with less variation. It provides a bonding method that obtains force, and its feature is that ethylene is used as the vulcanized rubber sheet in bonding vulcanized rubber sheets together or vulcanized rubber sheets and thermoplastic elastomer sheets.

An adhesive material (3) made of thermoplastic elastomer is applied to this butt part (2) (1) (
MM is performed so as to straddle 1). After that, a hot air welding machine with a rotatable pressure roll and a hot air device is placed on the adhesive tape (3), and while blowing hot air of approximately 400 to 600°C onto the surface of the adhesive material (3), the pressure roll is used to bond the adhesive. The material (3) is rolled into a vulcanized rubber sheet (11+l) and the vulcanized rubber sheet +11 (11 pieces are joined together).

When using a hot air welding machine, the hot air temperature should be 400 to 600°C, the free running speed should be 1 to 4 m/min, and the pressure of the pressure roll should be 5 to 10 kg/cm. Alternatively, the pressure roll and the hot air device may be prepared separately, and the worker may carry out the bonding work by holding the hot air device in one hand and the pressure roll in the other hand.
