[Prior Art] Conventionally, in waterproofing work in construction work, for example, on flat roofs, a construction method has been used in which a waterproof sheet is spread over leveling mortar and the sheet is adhesively fixed to the top of the joint material, for example, in Japanese Patent Laid-Open No. 56 There is a technique disclosed in Japanese Patent No.-20260.

[0003] This technique involves arranging joint material with the width of a waterproof sheet on the concrete layer of the building structure, forming a layer of heat-welding material over the entire length of the top of the joint material, and applying a leveling mortar layer to the top of the joint material. After forming, a waterproof sheet is placed over it, and the opposite edges of both adjacent waterproof sheets are butted together on the joint material. In this state, hot air is blown from above the waterproof sheets onto the butt portions of the waterproof sheets to melt the heat-welding material layer at the top of the inner joint material and adhesively fix the joint material and the edges of the waterproof sheets.

[0004] In this construction method, the waterproof sheet is adhesively fixed by melting the heat-welding material, so the adhesive strength of the adhesive surface is not affected by moisture, unlike glue adhesive, and the mortar layer is not affected during construction. No need to wait for drying. Further, it has the advantage that construction can be carried out even in rainy weather.

[Problems to be Solved by the Invention] However, in the above construction method, since hot air is applied from the top surface of the tarpaulin sheet, the surface of the tarpaulin sheet, which is directly exposed to the hot air, becomes considerably hotter than the melting temperature of the welding material layer. Even if a waterproof sheet is heat-resistant up to temperatures close to that temperature, the surface of the sheet can be damaged by heat, such as thermal contraction of the surface, peeling of the adhesive surface, or formation of pinholes, which can cause water leakage. There were cases where this happened.

Therefore, an object of the present invention is to prevent high temperatures from being applied to the surface of the waterproof sheet when heating the welding material layer.

[Means for Solving the Problems] In order to solve the above problems, in this invention, electromagnetic induction heating is applied from above a waterproof sheet to a conductor having a heat welding material layer on the upper surface, so that the conductor generates heat. The sheet is then adhesively fixed by the heat generated.

[Embodiment 1] This embodiment is shown in FIGS. 1 to 4. As shown in FIG. 1, first, the periphery of the waterproof construction surface 1 is surrounded by a conductor piece 3 such as a long piece of iron about 2 mm thick. On the inside thereof, a bar f made of a conductor piece 3 is provided at a required position.

On the other hand, a heat welding material layer 5 is provided on the conductor piece 3. The heat-welding material layer 5 is made of a thermoplastic synthetic resin such as a polyester resin that melts and exhibits adhesive properties, and is formed by applying the resin powder directly onto the conductor piece 3 to a desired thickness by a hot-melt method, or by applying the above-mentioned method in advance. Paste, for example, aluminum adhesive tape coated with resin onto the conductor piece 3,
A thermal welding material layer 5 may be formed on the conductor piece 3. In this way, when aluminum tape is used, the conductor surface is formed by the aluminum base material, so a non-conductor can also be used as the conductor piece 3, and the conductor piece 3 can also be made of an aluminum base material. can. The thermal welding material layer 5 may be formed in advance at a factory or the like, but it may also be formed on-site. Further, for the conductor piece 3, it is also possible to use a vinyl chloride-coated steel plate, etc., which has a heat-weldable coating layer.

On the other hand, a waterproof sheet 2 having the same shape as the construction surface 1 is made in advance at a factory or on site by joining rolled sheets of the required width at their side edges, and the construction surface 1 to which the conductor piece 3 is attached is made. Then, the waterproof sheet 2 is placed, sufficient positioning and fine adjustments are made by cutting, and an iron-type welding tool 6 shown in FIG. The tool 6 is provided with an induction coil 7 inside thereof, and the induction coil 7 is excited by an alternating current, and an eddy current is generated in the conductor piece 3 by the electromagnetic induction effect of the generated magnetic field. For this reason, the conductor piece 3 generates heat due to eddy current loss, and the heat-welding material layer 5 on the upper surface melts, thereby adhesively fixing the waterproof sheet 2.

As described above, in this construction method, the waterproof sheet 2 is not fixed to the construction surface 1 until the heat welding material 5 is melted with the welding tool 6, so the waterproof sheet 2 can be moved as many times as necessary on the construction surface 1. , you can glue it after correcting the misalignment. For this reason, in the conventional construction method using dry adhesive, the sheet 2 was divided into small parts and carefully pasted little by little to avoid "slippage", whereas this construction method requires fewer construction steps. Moreover, it can be finished neatly without special adhesive techniques. Note that the conductor piece 3 does not have to be in the shape of a wedge, and may be a simple one in which the conductor piece 3 is provided at a required position to fix the waterproof sheet 2, as shown in FIG.

On the other hand, when the conductor piece 3 is heated, the tool body 6 does not generate heat and is safe. Furthermore, since the heat generated by the conductor piece 3 inside the waterproof sheet 2 melts the heat-welding material layer 5, the surface of the waterproof sheet 2 is heated to a high temperature. and does not cause thermal damage, such as thermal shrinkage or pinholes. Furthermore, since the conductor piece 3 is directly heated, the heating efficiency is better than that of hot air heating. Moreover, since the waterproof sheet 2 is fixed using the thermal welding material 5, there is no need to wait for the construction surface 1 to dry during construction, as in the case of using conventional hot air, and construction can be performed even in rainy weather.

Furthermore, since the welding tool 6 does not directly touch the heat welding material layer 5, the welding material 5 does not stick to the tool 6, and the user is not bothered by unpleasant odors or smoke. In addition, the welding material 5 can be easily reattached or modified by applying the tool 6 to the adhesive area.
This work is easy because it can be remelted, and the waterproof sheet 2
As for the finish after construction, the conductor piece 3 is as thin as 2 mm, so protrusion from the waterproof sheet 2 is not a concern. Note that the thickness of the conductor piece 3 is not limited to 2 mm, and can be appropriately selected depending on the construction surface (the same applies hereinafter).

[0016] Furthermore, in cases where it is not possible to bring the large waterproof sheet 2 to the construction surface 1, it is also possible to bring in a rolled sheet and cut it into sheet pieces of the required length, as in the past. However, in a factory, a waterproof sheet 2 of a size that can be brought in to cover the construction surface 1 in two to three pieces may be made by joining rolled sheets together and used. In either case, each waterproof sheet piece is fixed to the conductor piece 3 with a welding tool 6, and the edges of one side of each sheet are overlapped, and the overlapped edges are melted and bonded using a solvent or hot air as in the past. . The adhesion does not have to be performed on the beam f, but may be performed on the conductor piece 3 as shown in FIG. At this time, the waterproof sheet pieces may be butted together in the same manner as in the past, but in that case, it is preferable to perform a waterproofing treatment such as caulking on the joint edges.
