Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an outer wall insulation structure for buildings and structures. BACKGROUND OF THE INVENTION It has been advocated that buildings, such as wooden buildings, be provided with an external wall insulation structure from the standpoint of livability and energy conservation. This is 1/2 of the current amount of kerosene used.
This is because there are economic and psychological advantages such as the amount of electricity used by coolers and the like can be reduced by about 1/3, various problems caused by condensation etc. can be eliminated, and livability can be greatly improved.

However, conventionally, for example, mortar walls and walls using siding materials were made by filling the main pillars and between the studs with glass fiber, nailing a lower pond board such as lath board on top of it, and placing a waterproof sheet on top of it. Stretch it.

After that, if you have a mortar wall, you can fix the lath material with a stable and apply mortar wall material on top of it, or if you are using siding material, you can either provide a rim on the waterproof sheet or install a waterproof sheet. It was common for the outer wall to be formed by directly fixing the rim to the main pillars and studs, and then nailing siding material thereon.

However, in the case of this type of exterior wall structure, mortar walls (2ON)
The heat transfer coefficient is approximately 2.3 Kcal / rrr h”
C, which is in a bad position as a heat insulating structure. In other words, the national insulation standard is 0.5 to 0.9 Kcal for walls.
/rd h'c. In addition, poor insulation properties mean that differences in temperature are directly transmitted to the mortar wall material and siding material, which increases the imbalance in the expansion and contraction ratios of the various constituent materials of the composite laminated structure, resulting in mortar wall spalling, Cracks were occurring more quickly, and the joints of the siding materials were often dislodged. Furthermore, the large heat transfer coefficient inevitably leads to the occurrence of dew condensation, which has the disadvantage of corroding the structural materials and causing the glass fibers to become wet.

In order to eliminate these drawbacks, the present invention is designed to: The object of the present invention is to provide a thermal insulation structure for buildings that has greatly improved construction efficiency.

EMBODIMENT OF THE INVENTION Below, one Example of the thermal insulation structure for buildings based on this invention is described in detail using drawings. Figure 1 is an explanatory diagram showing a cross section of an architectural insulation structure that combines siding boards and composite boards, where 1 is the main pillar, 2 is the stud, 3 is the interior base board, and the soil is composed of the composite board. A resin foam 5 (hereinafter simply referred to as foam) is sandwiched between sheet-like materials 6 and 7, and is mainly used as a cushioning material, a heat insulating material, a waterproof material, a sound absorbing material, and a material for controlling the height difference of the base. It functions as a moisture barrier. A specific example thereof is a configuration as shown in FIG. 2 (al~←). That is, the ta1 diagram shows a composite board with adhesive tape 6α attached to both ends of the form 5, and the ib1 diagram shows a sheet-like material 6.
．． A composite board in which a form 5 is sandwiched between 7 and 7, (Figure C1 is a composite board in which a face material, a composite core JfA8, such as PB, ^It % Pe-, wire mesh, or asbestos) is interposed in the middle of the form 5. , +d1 shows a composite plate in which one of the sheet-like materials has overlapping pieces 7a protruding from the two sides of the form 5, (Fig. 81 shows a composite plate in which the overlapping pieces 7a of the sheet-like object 7 protrude from the four sides of the form 5 To explain further, the size of the composite board ↓ is width 900++n x length 1

It consists of one type of foam, a foam made by bonding and integrating inorganic hollow particles such as pearlite grains and shirasu balloons with an adhesive, and a foam added with mineral fibers such as rock wool and glass wool.Of course, soft polyurethane foam It also includes a foam in which a thin layer of hard foam is formed on both surfaces.Also, the sheet-like material 6.7 may be of the same or different material, and is mainly used as a release material, a reinforcing material, a heat insulating material, a sound insulating material, Consists of one or more types of noncombustible materials, sound-absorbing materials, etc. Specific examples include gravel 4 = figure → Yoli half ÷ asphalt felt, terfelt, synthetic resin film, rubber sheet, and polyethylene sheet, asbestos paper, lead. foil, kraft paper,
A non-combustible thin film (a sheet-like material made by laminating metal foil on a product name KG receipt, etc.). 9 is a siding board (hereinafter simply referred to as a board), for example a composite board as shown in Figures 3 to 6. (Surface material A, core material B, back material C

It consists of one type of board as shown in fl, and is mainly used as exterior material,
It is useful as a cosmetic material. The size of the board 9 is 2424 to 7272 m in length and 180 to 450 m in width.
The thickness is approximately 10 to 50 mm.

It was C. Furthermore, no dew condensation phenomenon was observed.

Comparative Example In addition, the heat transmission coefficient of a structure in which the above-mentioned true wall was directly attached to the body rim or the like was about 1.12 Kca'l/rrrh''c, and there was dew condensation at the joints.

Furthermore, in the double wall structure, vibrations from the lli body were hardly propagated to the board in the example, whereas a rattling sound was heard in the comparative example.

What has been described above is only one embodiment of the thermal insulation structure for buildings according to the present invention, and as shown in FIG. You can also. In this case, cracks were less likely to form in the mortar wall 11.

As mentioned above, the architectural insulation structure according to the present invention has a lightweight composite board that is waterproof, moisture-proof, and heat-insulating, and is interposed between the 11 panels and the board, making the wall highly insulating and highly efficient. It has the characteristic that it can be formed by In addition, since the composite plate has elasticity and cushioning properties, springback acts at each striking portion and contact portion, resulting in a more airtight mounting structure and improved waterproofness and air impermeability.

Furthermore, when forming a cement mortar wall, the insulation, elasticity, low water absorption, and low moisture absorption of the synthetic resin foam,
Because it has functions such as adhesion between mortar and synthetic resin foam, there will be no cracking or peeling of the mortar wall, and there will be no corrosion of the constituent materials.In addition, it exhibits excellent heat insulation and dew condensation prevention functions. There is.
