シートの接続方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for connecting thick plastic sheets by thermal bonding (main bonding) using a heat seal tape, and in particular, to a method for connecting thick plastic sheets by thermal bonding (main bonding), and in particular, to This invention relates to a method for connecting thick plastic sheets by temporarily adhering heat-seal tape using a device.

最近、広い巾を有する厚手のプラスチツクスシ
ートを、潅漑用の河川、小さい池等に全面的に敷
いて、水が地中にしみこんでしまうことを防止し
ようとする試みが行われつつある。 Recently, attempts have been made to spread wide, thick plastic sheets over irrigation rivers, small ponds, etc. to prevent water from seeping into the ground.

一般に、約１mm以上の厚手のプラスチツクスシ
ートは、大きな巾のシートを成形機から直接成形
して得ることが困難であり、成形機から直接成形
される厚手のシートの巾は最大クラスで約200cm
程度であつたので、広い巾を有する厚手のプラス
チツクスシートの製造は、複数のシートを互いに
貼り合わせて接続することによつて行われてい
た。 Generally, it is difficult to obtain thick plastic sheets of approximately 1 mm or more by directly molding a wide sheet from a molding machine, and the width of a thick sheet directly molded from a molding machine is approximately 200 cm in the largest class.
Because of this, the manufacture of thick plastic sheets with wide widths was accomplished by laminating and connecting multiple sheets together.

しかし、厚手のプラスチツクスシートを貼り合
わせて接続する方法としては、例えば、厚手のシ
ートを熱融着する方法が通常行われるが、この熱
融着は、厚いシートの熱伝導が悪いために、極め

トにも巾の制限があり、その巾はせいぜい約10ｍ
程度である）、潅漑用の河川、池等の施工現場に
おいて長大な厚手のシートの接続を簡易的に行う
ことはできなかつた。 However, as a method of bonding and connecting thick plastic sheets, for example, the method of heat-sealing the thick sheets is usually used, but this heat-sealing has poor thermal conductivity of the thick sheets. It is extremely difficult, and in reality, it is only carried out in factories equipped with special equipment (there is also a width limit for factory-produced sheets, which can only be about 10 meters wide at most).
However, it has not been possible to easily connect long thick sheets at construction sites for irrigation rivers, ponds, etc.

従つて、広い巾を有する厚手のプラスチツクス
シートによる潅漑用の防水施工という上述の試み
は、実施されることが少なかつた。 Therefore, the above-mentioned attempts to waterproof irrigation systems using thick plastic sheets having a wide width have rarely been carried out.

いだし、本発明を完成した。 The inventors of the present invention have conducted intensive research on a method for connecting thick plastic sheets (thickness: 1 to 4 mm) easily even at construction sites. The tape is used to temporarily bond the heat-sealing tape to the edge of the thick plastic sheet by a specific temporary bonding device at a low temperature of about 50-110℃, and then at a high temperature of about 120-250℃. The present invention was completed by discovering a method for connecting thick plastic sheets by heating the heat-sealing sheets and thermally bonding them together.

のである。 As described above, the method of the present invention allows the heat seal tape to meander by simply moving the temporary connection device, which can be easily moved linearly without meandering, along the overlapped portion of thick plastic sheets. By using this temporary adhesion method, the subsequent main adhesion work can be done without causing wrinkles or misalignment of the heat seal tape. This can be done effectively without creating bubbles or peeling between the heat-sealing tape and the thick sheet.Moreover, since the thick sheet is not exposed to excessive heat history, the thick sheet itself can be sealed. will not be thermally deformed (curled), wrinkled, or melted and torn.
It hardly impairs the durability of thick sheets.

に仮接着される。 To explain the temporary connection device 3 in more detail, the metal roll 32 is used to perform temporary temporary bonding of the heat seal tape 2 prior to the elastic roll 34, and is placed in front of the bottom of the temporary connection device 3. It consists of a straight (cylindrical) roll made of metal. Further, the elastic roll 34 is
It connects to the metal roll 32 to perform secondary temporary bonding of the heat seal tape 2, is provided at the rear of the bottom of the temporary connection device 3, and is made of foamed urethane. The roll 32 provided at the front is a metal straight roll, and the roll 3 provided at the rear is a metal straight roll.
The reason why 4 is an elastic roll is because the front roll 32
is required to be heat resistant to the heating of the preheater 33, and the temporary connection device 3 can be moved without meandering to connect the front roll 3 as shown in FIG.
2, the heat seal tape 2 is temporarily attached to the upper part 11a of the step in the overlapping portion 11, and the rear roll 34 is used to temporarily adhere the heat seal tape 2 to the remaining lower part 11a' of the step. By doing so, the heat seal tape 2 is reliably and easily temporarily bonded to correspond to the step difference in the overlapping portion 11 without meandering.

面双方を予備加熱して行つても良い。 Further, the preheater 33 is constituted by a heating line gas burner provided in front of the metal roll 32, and heats the adhesive layer of the heat seal tape 2 to a low temperature of 50 to 110°C, particularly 60 to 100°C. This makes it possible to preheat uniformly and reliably across its width. Incidentally, the preheating of the heat seal tape 2 may be performed before the heat seal tape 2 is pressed by the metal roll 32. Therefore, the preheating by the preheater 33 is performed so that the heat seal tape 2 is heated as shown in the figure. For example, instead of pre-heating the adhesive layer of the heat-sealing tape 2, the overlapping portion 1 may be heated immediately before the temporary connection device 3 is suspended on the temporary connection device 32.
This may be carried out by preheating the surface of the heat seal tape 1 or by preheating both the surfaces of the adhesive layer of the heat seal tape 2 and the overlapping portion 11.

The heat seal tape 2 is wound around three guide rolls 35, 35, 35 between the supply roll 31 and the metal roll 32, and the heat seal tape 2 is wound between the guide rolls 35, 35, 35 as shown in the figure. It is made to run in a meandering state and is supplied to the metal roll 32. Each guide roll 35, 35, 35
is provided with flanges (not shown) on both sides thereof to prevent the heat seal tape 2 from shifting in the width direction. Heat-sealing tape 2 is given a certain tension by running on guide rolls 35, 35, 35, and is pressed against overlapping portion 11 by metal roll 32 and elastic roll 34 in a preferable state. In addition, the guide roll 35,
A brake may be attached to one of the guide rolls 35, 35, for example, located in the center, so that the tension force can be adjusted.

The edges and the heat seal tape 2 are bonded (fused) by heating as shown in FIG. In this case, in order to prevent the flame of the gas burner 5 from reaching both sides of the temporarily bonded heat seal tape 2, an appropriate flameproof wall, flameproof screen, etc. should be installed, or a flameproof sheet or board should be installed. It is appropriate to arrange these on the surfaces of the thick sheets 1, 1' on both sides of the overlapped portion 11 of the heat seal tape 2. Further, the above-mentioned preheating and the above-mentioned high-temperature heating are not only carried out using the flame of the above-mentioned gas burner, but also using other known heating means, such as electric heaters, infrared heaters, other hot wire heaters, heating rolls, This can be done by using an electric iron, spraying a heating medium, etc. Other pressing means may also be used for the pressing roll 6. Furthermore, in the method of the present invention, for example, after completing the temporary bonding work of the heat seal tape 2, the subsequent heat bonding work at a high temperature may be performed, or both processes may be performed almost simultaneously with a slight time difference. It can also be carried out in close succession.
