Abstract

<P>PROBLEM TO BE SOLVED: To simplify a connecting work and to shorten a time required to bond by heating a waterproof water barrier sheet thereon or from a slightly separated place by electromagnetic induction heating to melt a thermoplastic material. <P>SOLUTION: A method for bonding the waterproof water barrier sheet 1 comprises the steps of superposing ends 4a, 4b of the waterproof water barrier sheet 1, and connecting the ends 4a, 4b of the sheet 1. The method further comprises the steps of interposing a connecting tape 5 containing a metal member in a thermoplastic material at a bonding part, moving the tape 5 along the bonding part while the tape 5 is heated and melted by an electromagnetic induction heater D, and sequentially bonding the sheet. <P>COPYRIGHT: (C)2003,JPO

ている。Therefore, normally, a work of bringing a sheet having a certain width (for example, about 1 to 2 m) to the site of the disposal site and laying it while joining the sheets is performed. However, it is too inefficient to bring in only one sheet, so a predetermined number of waterproof / water-impervious sheets were joined in advance in the factory, and a certain number of sheets became a unit. By using a wide waterproof / impermeable sheet, the work of joining at the site is reduced and the laying efficiency of the work of laying the waterproof / impermeable sheet at the disposal site is improved.

せていき、順次接合してゆくことを特徴とする。According to a third aspect of the present invention, there is provided a waterproof / water-impermeable sheet joining method in which edges of the waterproof / water-impermeable sheet are superposed and joined to each other. In the joining portion, a metal net material is embedded in a thermoplastic material. With a bonding tape intervening, the thermoplastic material is melted by heating the metal net material in the bonding tape with an electromagnetic induction heater, and the edges of the waterproof / water shield sheets are heat-fused to each other, and electromagnetic induction is applied. It is characterized in that the heating machine is moved along the joining portion and the joining is sequentially performed.

き、順次接合してゆくことを特徴とする。According to a fourth aspect of the present invention, there is provided a method of joining waterproof / impermeable sheets in which end portions of waterproof / impermeable sheets are superposed and joined to each other, wherein the joining portion is a joining tape in which a metal plate is embedded in a thermoplastic material. The metal plate in the joining tape is heated by the electromagnetic induction heater to melt the thermoplastic material and heat-bond the end portions of the waterproof / water shield sheet to each other. It is characterized in that it is moved along the joint portion and is sequentially joined.

合するのに要する時間も短縮することができる。According to the above method, the metal tape which generates heat by electromagnetic induction heating is included in the bonding tape made of the thermoplastic material in various forms, so that the metal tape can be placed on the waterproof / water shield sheet or at a distance from the waterproof / water shield sheet. Even from this point, the thermoplastic material can be melted by heating by electromagnetic induction heating.
Therefore, since it is not necessary to directly heat the joint surfaces, it becomes extremely easy in terms of work, and the time required for joining the waterproof / waterproof sheets can be shortened.
