Abstract

PURPOSE:To simplify the welding of a waterproof sheet by putting the upper electrode and the earth electrode of a high frequency heater on a sheet fixture, above the water sheet layed of the metallic plate-shaped sheet fixture, and applying high frequency while pressing them. CONSTITUTION:On a sheet fixture 3, a coated layer 5 weldable with a waterproof sheet 2 is formed. Moreover, a hand-type high frequency heater 6 is provided with a high frequency generator 7, an earth electrode and an upper electrode 10 and 11, etc. Next, in the case of welding the sheet 2 to the fixture 3 fixed to a building 1, the electrodes 10 and 11 are carried right above the fixture 3 over the sheet 2 so as to do pressure-welding. And the fixture 3 doubles as a lower electrode, and a closed circuit is formed between the upper and lower electrodes, and the fixture 3 is heated at a high frequency voltage to dissolve a layer 5, thus the sheet 2 is welded to the fixture 3. Accordingly, it can be welded simply and securely.

４に溶着固定する。There are various ways to install the waterproof sheet, one example of which is the insulation method (waterproof sheet floating method).
As shown in Fig. 4, this construction method involves applying a coating film that can be welded to the waterproof sheet at multiple locations corresponding to appropriate locations on the central side of each waterproof sheet 22, excluding the periphery, on the partition surface 21 on which the waterproof sheet is to be laid. After fixing the sheet fixing tool 24 in the form of a metal plate with a metal plate 23 on the surface by driving screws 25, each waterproof sheet 22 is laid, and the overlapping edges of the laid waterproof sheets with the adjacent waterproof sheets are welded (not shown). ), then attach the sheet fixing tool 2 to the appropriate place on the center side of the tarpaulin, excluding the periphery.
Weld and fix to 4.

Inject the solvent 26 using the syringe 27 (Tokuma Sho 53-3 1 32
No. 4). In the figure, 28 is an injection needle of the syringe 27.

）。A sheet fixing device in the form of a metal plate whose surface has a coating layer that can be welded to the tarpaulin sheet is fixed in advance to the surface where the tarpaulin sheet is to be laid by driving screws, and then each tarpaulin sheet is laid and the surface side of the tarpaulin sheet is fixed. Even if the solvent is injected toward the surface of the sheet fixing device, the welding between the waterproof sheet and the sheet fixing device may be incomplete if the outside temperature is low.
Therefore, hot air is blown onto the surface of the tarpaulin sheet where the sheet fixing device is located, but the welding process is extremely complicated. By the way, there is a method that uses high-frequency heating equipment for welding.
However, conventionally used high-frequency heating devices have a high-frequency generator and a press device mounted on the outer frame, and an upper electrode is connected to the high-frequency generator with a lead wire, and the press device presses the workpiece by moving up and down. , a high-frequency circuit is formed through a metal table that receives the workpiece, and in order to weld the workpiece, the workpiece, regardless of its size, must be placed on the table, so a sheet fixture fixed to the building is used. Although it is not possible to place the waterproof sheet to be welded thereon on the table of the high-frequency heating device, fortunately a hand-type high-frequency heating device has been developed (Utility Model Application No. 60-99798).

An upper electrode is constructed at the pole part through an insulator, and although this device itself does not have a lower electrode that opposes the upper electrode, there is a sheet fixing device on the underside of the waterproof sheet laid on the building. Since it is fixed to the building, the hand-type high-frequency heating device is carried by the handle onto the waterproof sheet that has been laid down, and the ground electrode and upper electrode are placed on the sheet fixture and attached to the sheet fixture. By press-welding, the sheet fixing device in the form of a metal plate doubles as the lower electrode, forming a closed circuit with the upper electrode, and a high frequency voltage is applied, which heats the sheet fixing device and melts the coating layer on the surface. The waterproof sheet can be reliably welded, the work of welding the waterproof sheet and the sheet fixing tool can be extremely efficient, and waterproofing work can be carried out even when the outside air is low temperature without worrying about this.
