Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the construction of construction materials for roofs, walls, etc., which are joined by heat fusion, even if the weather and temperature during the construction are unsuitable for the work. The present invention relates to a joint structure for building materials capable of performing the following.

[0002]

2. Description of the Related Art In recent years, as a building material for constructing a roof, a wall, etc., a durable and weather-resistant synthetic resin is adhered to or coated on a metal plate to form a two-layer structure of a metal plate and a synthetic resin material. Building materials made of such materials are increasingly used. Further, this type of joining means for building materials is often based on heat fusion.

[0003]

A heat-sealing apparatus is used to join building materials as described above. However, in order to perform a heat-sealing operation using the heat-sealing apparatus, it is necessary to use a heat-sealing apparatus. The synthetic resin portions are joined by heat fusion. To do this, the weather and temperature must be favorable. That is,
If the heat fusion operation is performed during strong winds, the hot air spouted from the hot air jet nozzle of the heat fusion device will be diffused by the external strong wind, and it will be extremely difficult to perform heat fusion at a predetermined location of the synthetic resin for building materials. It will be difficult.

Further, when the operation is performed in a situation where the air temperature is extremely low, the hot air blown out from the hot air blowing nozzle of the hot fusing device is cooled, so that the hot air blown out of the hot air blowing nozzle is melted enough to heat fusing the synthetic resin portion of the building material. Can't do it. Further, the hot-air jet nozzle of the heat-sealing device is inserted into the overlapping portion between the ends of the adjacent building materials, but the heat-sealing device inserts the overlapping portion between the building materials into the corner portion of the base portion or the like. In such a case, the hot-air jet nozzle cannot reach the corners, and the heat fusion at the corners and at the ends becomes insufficient. Further, in the construction of a deformed roof having an uneven portion on a base portion, a heat sealing apparatus is particularly unsuitable.

[0005] In the heat fusion, if the hot air from the hot air jet nozzle is not properly applied to the synthetic resin of the building material, the synthetic resin is excessively melted, and the metal portion of the lower layer is exposed. It is possible. In addition, since not only the hot air but also the hot-air jet nozzle has a high heat, if the operation is wrong, the hot-air jet nozzle may sufficiently melt the synthetic resin.

[0006]

The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, have found that the present invention relates to a construction in which a thin metal sheet is coated with a synthetic resin film which can be thermally fused. The building material is constructed by joining the end portions of the material A with each other and joining the overlapped portion through a means of resin welding to form a building material. In the construction of lumber, even if the weather and the temperature at the time of construction are unsuitable for the work, the construction work can be performed and the above-mentioned problem has been solved.
