Abstract

PURPOSE:To carry out a connection of, e.g., intratunnel waterproof sheets firmly and in good workability, by heating to a transparency point the specified portions formed on the hot-melt adhesive layers at the end of each film to be connected. CONSTITUTION:For example, either or both of sheets 1 and 1' to be connected each other is coated with a transparent hot-melt adhesive of lower melting point than those of said sheets (said adhesive e.g., being prepared by blending an ethylene-vinyl acetate copolymer with a resin such as rosin ester) to form adhesive layers 2, 2'. On the surfaces of these layers, is formed a finely rough pattern using, e.g., a knurling tool, to opacify those parts. Subsequently, the resulting layers are mutually brought into contact followed by heating to a transparency point the opacified portions 3, 3' by, e.g., a hot-air stream, thus achieving the objective.

[Detailed Description of the Invention] The present invention provides a method for reliably connecting sheets with ease of construction! , 1. In particular, the present invention relates to a method of connecting large sheets such as waterproof sheets placed in a tunnel with an adhesive that melts when heated, such as a true-melt thread adhesive.

When installing a tarpaulin sheet, connect the - tarpaulin sheet and other tarpaulin sheets one after another.
If there is even a slight gap of 11ζ at the connection point, active water from the ground side will leak through this gap to the secondary concrete side, so it is desirable to connect the sheets in a watertight manner. Furthermore, when connecting sheets, it is also desirable to be able to easily align the sheets with each other and to connect them reliably with a simple method.

The present invention has been made in view of the above circumstances, and involves heating one or both of the connecting tubes of the sheets to be connected to each other with a substance having a melting point lower than that of the sheets, thereby melting the sheets.
At the same time, the surface of this contact x1c11 layer is made opaque by knurling or the like without forming minute irregularities, and then the adhesive layer is made opaque. By heating and adhering until the opaque portion becomes transparent, it can be determined whether the sheets are firmly adhered to each other or not, using whether the opaque portion becomes transparent or not as an indicator. This allows the sheets to be connected to each other without making any mistakes, as well as ensuring that the sheets are connected securely without forming any gaps. Therefore, it is an object of the present invention to provide a method for connecting sheets that can completely prevent water leakage at the point where the roof is attached.

Therefore, if there is a problem in the method of connecting the sheets 1.1' to each other as described above, it is possible to bond the sheets 1.1' with a bonding agent A5 that melts when heated, such as a hot melt yarn bonding agent 5 having a lower melting point than that of the sheet 1.1'.

It goes without saying that there is no mistake in stopping the work in jiiJ when the two are completely LN Ii, and the engraving agent Nt 2 e 2'
After the joint has been completely removed, there is no risk of excessive heating of the connecting part (adhesive part) 4 by continuing the operation.

Therefore, since the adhesive layers 2 and 2' can be completely bonded and integrated without any mistakes, the connecting portion (adhesive portion) 4
is in a completely wet state, and there is no fear of water leaking from the connecting portion 4. Therefore, the above-mentioned method of connecting the seam 41.1' can be suitably adopted as a method of connecting a waterproof sheet disposed in a tunnel. It is.

On the other hand, if no opaque parts are formed on the adhesive layer due to fine irregularities, it is possible to detect whether or not the adhesive layer has completely adhered. It may happen that the gluing operation is stopped or, conversely, it continues even after complete gluing, so that the adhesive layer is not reliably bonded - gaps may appear or remain in the connection flB. Note, there is a risk of water leaking from the jY connection, and the object of the present invention cannot be achieved.

Furthermore, depending on the above connection method, the sheet 1.1'
Since adhesive 1'W2t2' is formed, it can be easily bonded by simply heating at the construction site, and the mutual positioning of adhesive layers 2 and 2' can be easily
ij can be easily carried out, and the splicing work is also carried out by determining whether or not the opaque portions 6 and 6' are made transparent. Since it is a J, work efficiency is good, and the work of connecting sheets can be done efficiently by deJ.

In addition, in the above implementation, fine irregularities were formed on the entire surface of the adhesive layers 2 and 2' to form an opaque portion on the entire surface, but these irregularities were formed by knurling. The fine irregularities do not necessarily have to be formed on the entire surface, but may be formed partially to give the surface a partial opacity ratio. However, in this case, it is preferable that the circular irregularities, and hence the opacity + SB portion 6, be formed continuously along the length direction of the boat accommodation 1J layer 2 as shown in FIG.
Thereby, it is possible to reliably judge whether the light adhesion is broken or old over the entire graft layer 2.

Furthermore, in the above practical example, adhesive layers 2, 2' are formed on both sheets 1.1', respectively, and these

As explained above, ``Ki-en Ichishi'' is a method in which two sheets to be connected to each other are heated and bonded with an adhesive, and one or both of the sheets are bonded together. At the same time, the adhesive layer is formed with an adhesive that melts when heated and has a melting point lower than that of the sheet, and at the same time, fine irregularities are formed on the surface of this adhesive layer to form the part.

It is possible to connect the sheets while doing the I M, which makes it easy to work and connect the sheets to each other without making any mistakes. (6) It can be adhered to the fruit and has good water resistance at the connection part,
Therefore, it is suitably adopted as a method for connecting waterproof sheets, especially waterproof sheets disposed inside tunnels.

[Scope of Claims] 1. A method of connecting two sheets to be connected to each other using an adhesive that melts when heated, and one or both of the sheets is coated with a transparent material having a lower melting point than that of the other sheet. An adhesive layer is formed using a adhesive that melts when heated, and fine irregularities are formed on the surface of this adhesive layer to make the part opaque, and then the adhesive layer described in 11J is applied to the opaque part. A method for attaching sheets to a roof, characterized in that the facing sheets are connected to each other by heating until they become transparent. 2. The method according to item 1, in which fine irregularities are continuously formed along the length of the adhesive layer.
