Description

[Detailed description of the invention] This invention relates to the improvement of a heat-insulating exterior material that is suitable for use as roofing materials and exterior wall materials for livestock barns such as chicken houses, pig houses, and cow houses. The purpose of the present invention is to provide an insulating exterior material that is less susceptible to insect damage.

In recent years, a heat insulating exterior material 3a as shown in FIG. 1, which is formed by covering a synthetic resin substrate 1a such as a corrugated plate with a heat insulating material 2a such as styrene or urethane, has been used for poultry houses,
It is widely used as roofing material and exterior wall material for livestock barns such as pig pens to keep the environmental temperature comfortable in summer and winter, but when a plurality of such exterior materials 3a are laminated together as roofing material to cover the roof. for,
In order to prevent rainwater from entering through the bonded areas, each exterior material 3a must be bonded in sequence so that four layers are stacked at the corners.
For this reason, it is necessary to cut out the heat insulating material 2a in a portion corresponding to the overlapping margin of each exterior material 3a.

However, if the exterior materials are pasted one after another with the insulation material removed from the portion of the exterior material that corresponds to the overlap, insect pests such as mealworms can enter the holes exposed on the cut surfaces. There are many serious problems in which the insects invade and build nests, and in severe cases, they can pierce the insulation material like a honeycomb, and as a result, the expected useful life of the insulation material is significantly shortened.

The present invention was developed in view of the above circumstances, and it solves the problems of the conventional heat insulating exterior material, which is made of a synthetic resin substrate covered with a heat insulating material. In addition to cutting off the heat insulating material in the area corresponding to the overlap, a synthetic resin film is attached to the cut surface or paint is applied to the cut surface so as to close the hole exposed on the cut surface. This is intended to facilitate roofing work and provide an insulating exterior material that is less susceptible to insect damage.

An embodiment of the present invention will be explained below with reference to the accompanying drawings. Figures 2 and 3 show an embodiment of the exterior material of the present invention, and 1 shows a structure in which a synthetic resin corrugated plate is used as the synthetic resin substrate. The corrugated plate substrate has a heat insulating material 2 made of urethane, styrene, etc. adhered to its lower surface using an adhesive or the like. This synthetic resin substrate 1 is made of vinyl chloride, acrylic, polycarbonate, etc., or a synthetic resin board reinforced by adding glass fiber to these synthetic resins. Opaque, especially white, is desirable to prevent this.

In addition, the heat insulating material 2 has a portion corresponding to the overlapping portion of the exterior material 3, that is, one side portion 11 and the lower side portion 12 in the embodiment shown in FIG.
Furthermore, if the cut surface 4 of the excised portion is not smooth and the hole is exposed, the hole exposed on the cut surface is covered by covering it with a synthetic resin film or applying paint. This surface treatment prevents insects that feed on the insulation material, such as mealworms, from entering through the holes exposed in the cut surface 4 of the insulation material 2.

In addition, when performing such surface treatment,
It goes without saying that it is always desirable to apply insecticides effective against insect damage to insulation materials, such as chlorpyrifosmethyl and carbaryl.

FIG. 4 shows an example of the use of the heat insulating exterior material of the present invention as a roofing material, particularly when a plurality of exterior materials of the present invention are laminated together for roofing.

As shown in this figure, according to the exterior cladding material of the present invention, when a plurality of these are laminated together to cover a roof, the insulation material 2 in the overlapping portion of the exterior cladding material 3 is cut out, so that the overlapping portion Since there is no need for extra thickness or gaps, there is no risk of rain leaking.Also, since the insulation layer is formed almost flush with the inner surface of the roofing material, the insulation of the insulation material 2 is It won't affect the effect.

Moreover, the cut surface 4 of the heat insulating material 2 of each exterior material 3
1 and 41 are subjected to a surface treatment that closes the holes exposed on their surfaces, thereby effectively preventing the intrusion of insulation material-eating insects such as mealworms.

The exterior material of the present invention has the above structure, but
According to the exterior material of the present invention, the insulation material in the portion corresponding to the overlap of the exterior material is cut out in advance, and a synthetic resin film is pasted or paint is applied so as to close the holes exposed on the cut surface. Because of this, it is easy to install when multiple sheets are pasted together for roofing, exterior wall materials, etc., and there is no risk of insulation insect pests such as mealworms entering through the cut surfaces of the insulation, so livestock barns have been used in recent years. It can effectively prevent insect damage to insulation materials, which frequently occurs in Japan. Furthermore, since the heat insulating material 2 is removed from the overlapped portion of the exterior material 3, there is no need for excessive thickness or gaps in the overlapped portion, so there is no risk of rain getting into the roof. Since the heat insulating material layer is formed substantially flush with the inner surface of the material, the heat insulating effect of the heat insulating material 2 is not impaired.

In addition, although the example of use as a roofing material was explained in the Example, it cannot be overemphasized that the exterior material of this invention can be used not only in such an example but also as an exterior wall material. In addition, the synthetic resin substrate constituting the exterior material of the present invention may be a flat plate or other modified shape other than the corrugated plate shown in Figures 2 to 4. A similar effect can be obtained even if the value is changed to .
