Description

[Detailed description of the invention] This invention relates to an exterior wall material for buildings that has both heat collection and heat insulation effects.

There are two main types of building exterior wall materials:
One is wet wood and the other is dry wood.

This invention belongs to dry lumber among these.

In the past, the mainstream dry material was a composite of plasterboard and iron plate, which was relatively easy to conduct heat, but since energy conservation began to be called for, materials with insulation properties such as urethane have become available on the market. , coupled with energy conservation policies, seem to be well received.

However, it is difficult to say which is better from the point of view of energy conservation.

In the winter, uninsulated buildings are better at letting in solar heat, but they are inconvenient at night or when there is no sunlight.

Also, if the building is insulated, there will be a problem that it will not be able to absorb solar heat.

In other words, the problem lies in the fact that the properties of the material are thermally insulated or non-insulated.

For example, in the winter, a single material can perform a sufficient function as long as it has the so-called dual function of taking in solar heat on the solar irradiated surface and insulating the non-solar irradiated surface.

This invention provides an exterior wall material for buildings that provides both of the above-mentioned effects.

Hereinafter, one embodiment of the building exterior wall material according to this invention will be described with reference to the drawings.

Reference numeral 1 indicates an exterior wall material for a building, which is composed of a metal outer covering board 2, a heat insulating board 3, and a plasterboard board 4.

The outer cover plate 2 is provided with opposing inner protruding sides 6 and 7 by bending the end of the groove-shaped main body 5 inward, and also by folding back the inner protruding sides 6 and 7 to form an outer protrusion over the entire length in the width direction. forming the side 8 and the nailing side 9,
Furthermore, a long connecting groove 10 is formed between the inner projecting side 7 and the nailing side 9.

The heat insulating plate 3 for the outer cover plate 2 is made of a material with good heat insulation properties, such as foamed synthetic resin, and the heat insulating plate 3 is formed on the outer cover plate 2 as shown in FIG. The heat insulating board 3 has a width and thickness that can be inserted between the back surface of the groove-shaped main body 5 and the inner protruding sides 6 and 7, and the heat insulating board 3 has vertical bars 12 on the surface of the box-like body 11 having frames at the side ends. and horizontal bars 13 are provided at approximately the same intervals, and a large number of recesses 14 are formed between the vertical bars 12 and the horizontal bars 13.

A vent hole 15 passing through the bottom plate 11a of the box-like body 11 is provided in each upper portion of the recesses 14.

In the embodiment shown in FIG. 3, the bottom of the recess 14 and the vent 15 are provided at an angle.

The plasterboard plate 4 used by being superimposed on the surface of the heat insulating board 3 on which the recesses 14 are formed is a board having approximately the same size as the heat insulating board 3.

The heat insulating board 3 and the plasterboard board 4 configured in this way fit into the recess 1 as shown in FIGS. 1 and 2.
The plasterboard plate 4 is placed on top of the surface having a groove-shaped main body 5 and the inner protruding sides 6 and 7, with the plasterboard plate 4 facing the back side of the outer cover plate 2, and both left and right end portions thereof being grooved. It is constructed by being inserted into the portion 16.

The building exterior wall materials 1 constructed in this manner are, as shown in FIG. 5, nailed and fixed in parallel to the entire wall surfaces of the sun-radiated surface A and the non-sun-radiated surface B of a building.

At that time, the building frames 17, 17, . . . are successively connected and fixed with nails in the same way as conventional exterior wall materials.

In the figure, 21 is the foundation, 22 is the foundation, 23 is the inner wall, 2
4 is the underfloor space, 25 is the inner wall 23 and the building exterior wall material 1
...The ventilation space formed between them, 26, indicates the attic space.

Next, let's take a look at the function of the building exterior wall material 1 according to this invention in a building.

In winter, if the sun is shining from the right-hand direction in Fig. 5, the outer covering board 2 and plasterboard board 4 will be heated by the radiant heat of the sun's rays, and eventually the recess 1
4... The air inside is heated and flows into the ventilation space 25, and the cold air from the ventilation space 25 instead flows into the recess 14, where it is heated again and rises due to the air convection phenomenon.

The high temperature air in the ventilation space 25 rises and flows into the attic space.

In the underfloor space 24, cold air is sent into the ventilation space 25 to create a negative pressure, and the air in the ventilation spaces 27 and 28 begins to fall.

At this time, the heat is absorbed by the inner wall panel 23a, thereby warming the room.

On the other hand, on the non-solar surface B, the outer covering board 2 and the plasterboard board 4 are cooled, and the air in the ventilation space 28 accumulates in the recesses 14 and becomes still air that does not cause convection, and the insulation wall together with the building exterior wall material 1 It becomes.

In this way, this kind of exterior wall material for buildings can collect heat when there is sunlight, and can provide insulation on non-solar surfaces or at night.

In the summer, the underfloor vents and attic vents (not shown) are opened to release hot air outside and dispose of it to cool the building.

As described above, the building exterior wall material of this invention is a type of material that functions as both heat collection and heat insulation, and has a very large energy-saving effect.

In addition, this building exterior wall material has a heat insulation board and a plasterboard board stacked on the back side of the exterior cladding board, so
Not only does this improve the strength, but the recesses are reliably formed and have the effect of preventing air leakage.
