Electromagnetic inductive heating device

Abstract

The present invention relates to an electromagnetic inductive heating device for bonding a sheet to anchoring members comprising a conductive base and a thermoplastic resin layer, characterized by bonding the anchoring members to the sheet by heat deposition of the thermoplastic resin layer by heating of the conductive base, said device comprising: a heating means for heating the conductive base via the sheet by electromagnetic induction; a temperature measurement means for measuring the temperature of the sheet; and a heating time setting means for setting heating time by the heating means according to the temperature of the sheet. With the present invention, it is possible to provide an electromagnetic inductive heating device with which it is possible to desirably bond the anchoring members and the sheet even if there are large temperature changes in a covering surface due to seasons, weather, etc., and to reliably anchor a sheet, uniformly and without unevenness, to all anchoring members even if time is required to lay down the sheet.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2012-6892 for which it applied in Japan on January 17, 2012, and uses the content here. [0002] The present invention relates to an electromagnetic induction heating device, and more particularly to an electromagnetic induction heating device for laying sheets on a roof of a building for the purpose of waterproofing and the like. Background technique [0003] When laying a waterproof sheet on the roof of a building such as a building for the purpose of waterproofing, it is necessary to fix the waterproof sheet to the roof floor by some method. As one of the methods, it is known to use an electromagnetic induction heating device. fixed method. [0004] In the method of fixing a waterproof sheet using an electromagnetic induction heating device, for example, a plurality of fixing members having a thermoplastic resin layer such as a hot-melt adhesive on a disc made of a conductive...

Problems solved by technology

[0009] However, on surfaces exposed to the outside, such as the roof floor of a building, the temperature varies greatly depending on seasons, weather, etc., and even in a day, the temperature may vary greatly between day and night.

However, in the current situation, it is difficult to perform heating that takes into account the temperature difference between the part exposed to sunlight and the part that is not, because the operator manually adjusts the heating level in two stages according to the season, climate, etc. Minor adjustments to the level

[0010] Therefore, depending on the time of laying the waterproof sheet and the weather, it is difficult to obtain a good bonding state between the fixing member and the waterproof sheet. In addition, due to the wide base of the roof, etc., it takes time to lay the waterproof sheet. , even if a good bonding state can be ensured between a part of the fixing member and the waterproof sheet, there is a possibility that the bonding state of the other fixing member and the waterproof sheet is not good
