[0001]
BACKGROUND OF THE INVENTION
The present invention is a construction material capable of performing construction work even when the weather and temperature at the time of construction are unsuitable for the work in construction of the construction material for constructing roofs, walls and the like by joining by heat fusion. This relates to the joint structure.
[0002]
[Prior art]
In recent years, as a building material for construction of roofs, walls, etc., a construction made of a material having a two-layer structure of a metal plate and a synthetic resin material, in which a durable and weather-resistant synthetic resin is attached to or coated on a metal plate. Many materials are being used. In addition, this type of building material is often joined by heat fusion.
[0003]
[Problems to be solved by the invention]
A heat-sealing device is used to join the building materials as described above. However, in order to perform the heat-sealing operation using the heat-sealing device, the synthetic resin portion between the building materials is heat-sealed. And join. To perform this work, the weather and temperature must be suitable. That is, if heat fusion work is performed during strong winds, the hot air ejected from the hot air ejection nozzle of the heat fusion device is diffused by the external strong wind, and heat fusion is applied to a predetermined portion of the synthetic resin of the building material. Is extremely difficult.
[0004]
In addition, when working in a situation where the temperature is extremely low, the hot air ejected from the hot air ejection nozzle of the thermal fusion apparatus is cooled, and sufficient melting is performed to thermally fuse the synthetic resin portion of the building material. Can not. Furthermore, the hot air jet nozzle of the heat fusion apparatus is inserted into the overlapping portion between the ends of the adjacent building materials, but the heat fusion device inserts the overlapping portion between the building materials into the corner portion of the base portion. In such a case, the hot air jet nozzle cannot reach the corner end, and the heat fusion at the corner and the end becomes insufficient. Furthermore, in the construction of a deformed roof in which an uneven portion is present on the base portion, the heat fusion apparatus is particularly unsuitable.
[0005]
Moreover, 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 may be excessively melted and the metal portion of the lower layer may be exposed. . Moreover, since not only hot air but also the hot air jet nozzle is hot, if the operation is mistaken, the synthetic resin may be excessively melted by the hot air jet nozzle.
[0006]
[Means for Solving the Problems]
In view of the above, the inventor has intensively studied to solve the above-mentioned problems. As a result, the present invention can be applied to both ends of the flat type main plate in the width direction from the hanging side piece and the lower end of the hanging side piece. A synthetic resin film that can be heat-sealed is coated on the upper surface of a thin metal sheet having horizontal bottom pieces formed thereon, and is constructed as a building material, and the horizontal bottom pieces of the adjacent building materials are polymerized, and the overlapping portion In the construction of building materials, which are constructed by joining by heat welding, the construction material is joined by means of resin welding, the weather and temperature at the time of construction work. Even if it is unsuitable for construction, construction work can be performed and the above-mentioned problems are solved.
