Description

  The present invention relates to a waterproof sheet for a waterproof construction for a floor of a building or a sloped roof of a building, a floor of a house veranda or a roof balcony, or a waterproofing work for civil engineering, and the like. More specifically, a waterproof sheet construction method for mechanically fixing a waterproof disk on a waterproof construction surface. More specifically, a fixed disk plate whose upper surface is covered with a heat welding layer is fixed on the waterproof construction surface with screws, After installing a waterproof sheet, place an induction heating device on the upper surface of the waterproof sheet at a position corresponding to the fixed disk plate, and use it when constructing a waterproof sheet that melts and integrates the waterproof sheet with the heat-welded layer by induction heating The present invention relates to a positioning jig for an induction heating device.

  Conventionally, a waterproof sheet made of a synthetic resin is generally laid by a mechanical fixing method on the surface of an outdoor housing in a structure such as a building or a house in order to prevent rainwater or the like from entering. . This mechanical fixing is also called an insulation method, and a fixed disk plate made of a thermoplastic resin cover plate such as a vinyl chloride resin is attached to the surface of the structural body with a fixing tool such as a plug or a screw. A large number of fixings are installed in the existing state, and a waterproof sheet made of a resin compatible with the thermoplastic resin is laid on the surface of the housing so as to cover the fixed disk plate, and a thermoplastic resin layer is formed on the upper surface of the fixed disk plate. The waterproof sheet is laid by bonding with heat, bonding with a solvent or adhesive, or bonding with an induction heating device.

  In this case, it is necessary to position the induction heating device and the fixed disk plate so as not to be displaced in order to perform reliable bonding between the fixed disk plate and the waterproof sheet. If the positioning is estimated, the thickness of the fixed disk plate (usually a few millimeters thick) is not so thick, which may cause misalignment. become unable.

In order to prevent such displacement, an induction heating apparatus positioning jig (see Patent Document 1) and an induction heating apparatus provided with a positioning member (see Patent Document 2) have been proposed.

  However, in the technique of Patent Document 1 or 2, although the displacement of the induction heating device can be prevented, the coil bottom surface of the induction heating device and the waterproof sheet are in direct contact with each other, so that the coil bottom surface of the induction heating device becomes dirty. In addition, when used for a long period of time, the coil bottom surface of the induction heating device wears, making it impossible to perform proper positioning, as well as changing the distance from the fixed disk plate.

  The difference in the distance between the fixed disk plate and the induction heating device greatly affects the heating of the fixed disk plate. As a result, the thermoplastic resin on the fixed disk plate is insufficiently melted due to insufficient heating of the fixed disk plate, and the waterproof sheet. And sufficient fusion strength cannot be obtained. Further, when the fixed disk plate is heated to a higher temperature than necessary, the waterproof sheet is thinned.

  The present invention has been made in view of such a current situation, and the object of the present invention is to facilitate positioning, prevent contamination and wear on the bottom surface of the coil of the induction heating device, and manufacture at low cost. An object of the present invention is to provide a positioning jig for an induction heating apparatus capable of performing the above.

The means taken by the present invention to achieve the above object is to fix a fixed disk plate formed by laminating and integrating a thermoplastic resin on the upper surface of a conductive metal plate on a base surface on which a thermoplastic resin waterproof sheet is applied. And a positioning jig of an induction heating device used for construction of a waterproof sheet that is fused by placing the waterproof sheet on the upper surface of the fixed disk plate by placing the waterproof sheet on the fixed disk plate. The fixed disk plate having a sheet body larger than the coil bottom surface of the induction heating device, the sheet body being provided with a mark A corresponding to the outer periphery of the coil bottom surface, and fixed on the ground surface inside the mark A is the title B corresponding subjected to, the inner of the title B is that the positioning jig made of sheet (claim 1), the inner portion of the title B than the outer portion of the title B is mutable Is to have a positioning jig is a sex (claim 3), also a thermoplastic resin-made waterproof sheet on the lower ground of applying a on the upper surface of the conductive metal plate formed by integrally laminating a thermoplastic resin fixed disk Positioning of the induction heating device used for the construction of the waterproof sheet that fixes the plate and places the waterproof sheet on the fixed disk plate and fuses the waterproof sheet by induction heating on the upper surface of the fixed disk plate A jig comprising a sheet body larger than the coil bottom surface of the induction heating device, the sheet body is provided with a mark A corresponding to the outer periphery of the coil bottom surface, and is fixed on the base surface inside the mark A title B corresponding to the fixed disk plate is subjected is that the inner portion of the title B than the outer portion of the title B has a positioning jig is easily deformable (claim 2), the inner portion of the title B Cut is to have a positioning jig put (Claim 4), is that the further title A has a positioning jig is a step (claim 5).

  With the positioning jig of the present invention, the bottom surface of the coil of the induction heating device is not soiled, and even when used for a long time, the bottom surface of the induction heating device coil is not worn and the distance from the fixed disk plate can be kept constant. It becomes like this. As a result, it is possible to obtain a stable fusion strength for joining the fixed disk plate and the waterproof sheet.

  In order to fuse the waterproof sheet to the fixed disk plate by induction heating, as shown in FIG. 1, first, the positioning jig of the present invention is placed so that the mark B matches the position of the fixed disk plate. The coil bottom surface of the induction heating device may be arranged so as to match the mark A of the positioning jig, and a magnetic field may be generated by the induction heating device. The fixed disk plate is induction-heated, and the waterproof sheet and the fixed disk plate can be fused and bonded.

  The coil bottom surface of the induction heating device can be placed precisely in correspondence with the center of the fixed disk plate simply by aligning the positioning jig from the top of the waterproof sheet and placing it at the corresponding position of the fixed disk plate. Since the coil bottom surface and the fixed disk are in contact with each other without inclining, the joining operation is simple and accurate. In addition, the bottom surface of the coil of the induction heating device is not contaminated or worn.

  The fixed disk plate for joining the waterproof sheet is a disk (disk plate) made of a thermoplastic resin coated steel plate, but is a thermoplastic resin compatible with the waterproof sheet and a metal that generates heat by high-frequency induction heating. As long as it is a plate-like body obtained by laminating and integrating, the shape is not limited to a disc shape, and may be other shapes such as a square shape.

  The positioning jig of the present invention is shown in FIG. The positioning jig 3 is used to determine the position of the induction heating device when laying the waterproof sheet. The positioning jig 3 is made of a sheet body larger than the coil bottom surface of the induction heating device, and a mark A corresponding to the outer periphery of the coil bottom surface is applied to the sheet body. It is. The positioning jig 3 is made of synthetic resin, ceramic, glass, paper, wood, etc., and is preferably made of synthetic resin in consideration of workability and cost.
