Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement in the heat insulating structure of a roofing panel for a thatch and an exterior panel.

[Conventional technology]

Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 60-138928 as a heat insulating structure for a roofing panel for roofing and exterior panels, there is no rib between the inner and outer synthetic resin plates, or there is a rib. There is known an adiabatic corrugated plate which is integrally formed by being entirely filled with a resin foam.

Further, as shown in Japanese Utility Model Laid-Open No. 58-153622, rising engaging portions are formed on the left and right edges of a metal vertical roofing board, and the engaging portions are formed by a hanger made of an aluminum extruded material and a cover plate. Engaging vertical roofs are also known.

[Problems to be Solved by the Invention]

However, in the adiabatic corrugated sheet disclosed in Japanese Utility Model Laid-Open No. 60-138928, since the inner side surface plate and the outer side surface plate are formed of synthetic resin and the foam material is filled, the width and the thickness are reduced. Since it is limited to a certain size, it is impossible to select each face plate as an appropriate one according to various purposes of use, and there is little freedom, and the entire surface of foam material etc. When it is desired to use it in a place that does not require filling, it cannot be used, and the purpose of use for buildings is limited to a narrow range. In addition, since it is flammable, in addition to problems such as emitting toxic gas during a fire,
There was also a problem in terms of durability.

Further, in the above-mentioned Japanese Utility Model Laid-Open No. 58-153622, in the case of a structure that does not use a wooden board etc. as a heat insulating material, heat conduction between the inside and outside of the building is performed through the connecting part of the vertical roofing board, and the heat insulating function is There was a problem that it was not fully achieved. Further, in the above invention, it is impossible to provide a heat insulating space that can be adjusted by the roof plates.

The present invention is intended to improve the conventional problems as described above, and in order to more effectively exhibit the heat insulating effect, the roofing panel and the exterior panel for vertical roofing are roll-formed. It consists of two members, an outer side plate and an inner side plate,
It is an object of the present invention to provide a heat insulating structure in which various flat heat insulating holding plates are interposed between the inner and outer two-layer metal plates to form a heat insulating space and the size of the heat insulating space can be adjusted.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is an exterior structure in which the left and right joints of a metal roofing plate for roofing and a metal exterior plate are engaged by a suspension and a cover plate, a bolt and a nut, or caulking. In the above, the roof plate and the exterior plate are roll-formed into an outer face plate and an inner face plate, and the outer face plate and the inner face plate are provided with a required number of inward gutter-shaped receiving portions, respectively, and the inside of these. The outer receiving portions are integrally heat-insulated by a flat heat insulating holding plate.

[Action]

According to the present invention, a metal roof plate and a metal exterior plate are roll-formed into an outer face plate and an inner face plate, and a required number of inward gutter-shaped receiving portions are respectively placed on the outer face plate and the inner face plate. Since the inner and outer receiving portions are integrally heat-insulated by the flat heat-insulating holding plate, the following effects can be obtained.

That is, by adjusting the height of the flat-plate heat insulating holding plate, it is possible to freely adjust the vertical width of the heat insulating space formed between the outer side plate and the inner side plate. Therefore, in a cold region or a high temperature region where the sun is strong, it is possible to easily obtain a roof or the like having an excellent heat insulating structure by setting the above vertical width to be larger than the heat insulating function of a roof or the like in a warm region. You can

Further, the width of the heat insulating space can be freely adjusted by changing the number or the holding position of the flat heat insulating holding plate to the receiving portion. For this reason, it becomes possible to freely select it according to the required heat insulation function of the roof and the like, and by increasing the heat insulation holding plate, the strength of the roof and the like is also increased. Therefore, in addition to the heat insulation function, It is possible to easily and accurately reinforce a portion requiring strength.

In this way, by adjusting the size and number of the flat heat insulating holding plates by adjusting the vertical width or the horizontal width of the metal outer side plate and the inner side plate, it is possible to freely adjust the heat insulating space or the like that can be adapted to various purposes of use. Besides, it is possible to easily fill the non-combustible heat insulating material such as glass wool by utilizing this heat insulating space.

Moreover, the material and thickness of the metal inner and outer side plates are
It can be arbitrarily selected according to the purpose of use of the building, and since the flat plate-like heat insulating holding plate is lightweight, a light and strong heat insulating structure can be obtained.
