Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a novel thermally insulating wall for buildings.

[Background of the Invention] In recent years, energy conservation has become a social goal due to the rapid rise in energy costs and the uncertain future energy supply situation. Various energy-saving measures are being implemented, and as part of these efforts, insulation materials with the function of preventing heat dissipation and infiltration through walls, floors, ceilings, etc. are being developed with the aim of saving energy in buildings such as houses and buildings. is recommended.

[Prior Art and its Problems] Conventionally, as insulation materials for buildings, insulation materials containing a large amount of air, such as fibrous materials such as rock wool and glass wool, or synthetic resin foams, have been used.

However, since the fibrous material used as a heat insulating material basically consists of fibers containing a large amount of air, air may flow inside the fibrous material and the heat insulation efficiency may not be sufficiently improved.

In addition, the moisture contained in the air flowing through the fibrous body condenses due to the temperature difference, and this moisture accumulates in the fibrous body, gradually increasing the water content in the fibrous body and eventually forming a fiber. There is a problem when the particles aggregate at the bottom.

Furthermore, traditionally used insulation materials such as fibrous bodies and synthetic resin foams are very bulky and require considerable space to transport or store, and are themselves expensive and therefore There is also the problem that the cost of insulation is high.

Focusing on the shortcomings of such fibrous materials as heat insulating materials, aluminum foil, aluminum vapor-deposited film, etc. ( (Hereinafter, both may be collectively referred to as "aluminum film"). The insulation method using aluminum film basically uses aluminum film to block air flow in the thickness direction of building structures such as walls, floors, and ceilings, and also uses aluminum film inside the building structure. The idea is to create an air layer made of wall material, etc., use this air layer to increase insulation efficiency, and further increase the insulation effect by reflecting radiant heat on the surface of the aluminum film. be.

This method using aluminum film has a good insulation effect because air does not flow through the insulation material like the fibrous insulation material mentioned above, and furthermore, the water-containing insulation material coagulates due to condensation of moisture in the air. It is attracting attention as a new insulation method because it does not lose its insulation effect and is relatively inexpensive. However, it is relatively difficult to attach aluminum film to building structures. many.

In addition, heat insulating materials are known that are made by further improving aluminum films and are made by laminating aluminum films so that there is an air space between them, but like aluminum films, this is also difficult to attach to architectural structures. Furthermore, since the aluminum film laminate contains an air space, there remains the problem that it requires a considerable amount of space for storage or transportation.

[Object of the Invention] An object of the present invention is to provide a heat-insulating wall body for a building that is easy to construct and utilizes the excellent heat-insulating material of aluminum film.

[Summary of the Invention] The present invention provides a pair of self-supporting plate-like members having a connecting portion perpendicular to the longitudinal direction that bends only on one side in the center portion of the length, and having no bent portion. A pair of self-supporting plate-like members, the plate-like member having a connecting portion and the plate-like member having a connecting portion facing each other so that the bending direction is outward, and a plate having no bending portion. A frame body having a square or rectangular internal cross section, in which a shaped member and a plate-shaped member having no bent portion are arranged so as to face each other, and are connected so as to be bendable at the ends of each member,
A heat insulating structure made of at least one aluminum film stretched between a pair of plate-like members having no opposing bent portions so as to cover the internal cross section of the frame body. There is provided a heat insulating wall body for a building, characterized in that two or more wall bodies are arranged in parallel in each of the vertical and horizontal directions along the above-mentioned cross section.

DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described in more detail with reference to the accompanying drawings.

FIG. 1 is a perspective view schematically showing a preferred embodiment of a heat insulating structure constituting a heat insulating wall of a building according to the present invention.

As shown in FIG. 1, the heat-insulating structure constituting the heat-insulating wall of the building of the present invention is basically composed of plate-like members A, B, C, and D that are sequentially connected at their ends. An aluminum film Q is stretched between a frame body with a square or rectangular internal cross section and plate members A and C facing each other so as to block the inside of the frame body along the above cross section. Become.

There is no particular restriction on the material of the plate-like member as long as it has enough rigidity to maintain its own shape. Examples of materials that make up plate-like members include:
Mention may be made of cardboard, synthetic resin foam, plastic, wood and metal. Moreover, various composite materials made of these materials can also be used.

In particular, cardboard is easy to form into a frame;
Furthermore, since it itself has heat insulating properties, it is suitable as a material for plate-like members.

Each of the plate-like members is foldably connected as shown in FIG. It is provided.

For example, if two long pieces of cardboard are used as the constituent material of a plate-like member, as shown in FIG. In the case of an embodiment in which the connection is made at the center part 1b in the direction, the connection part 2a of two long cardboards,
By marking the portions corresponding to 2b, 2c, and 2d, the connecting portions 2a, 2b, 2c, and 2d are connected in a foldable manner. However, the connection of the plate-like members is not limited to the above-mentioned mode, and the plate-like members A, B, C,
Of course, it is also possible to manufacture each D separately and connect them with engagement means such as adhesive tape or hinges.

Further, the connecting portions 4a and 4b can be connected by the same connecting method or means as the above-mentioned connecting portions. When folding the heat insulating structure, it is possible to fold the connecting parts 4a and 4b so that they bite into the inside of the frame 3, but usually they are folded so that they protrude outside the frame 3. It will be done. Therefore, the connecting portions 4a, 4b are generally connected so as to be foldable on the outside of the frame.

The frame body 3 constituted by the plate-like members A, B, C, and D has a square or rectangular internal cross section. The shape of the internal cross section may be either square or rectangular, and the shape can be set as appropriate to match the shape of the heat insulating building structure of the present invention constructed by combining heat insulating structures. can.

In the heat insulating structure, at least one aluminum film Q is stretched between opposing plate-like members A and C so as to block the frame body 3 along its cross section.

The aluminum film Q needs to be stretched between at least the opposing plate members A and C.

As shown in FIG. 1, the foldable heat-insulating structure is attached to a cross section near the center inside the frame 3 between plate-like members A and C that do not have a connecting part in the center. It is stretched out.

However, when stretching the aluminum film,
It is not limited to this part, for example,
It can also be stretched over the side edges in the length direction of the plate-like member constituting the frame 3.

It is necessary to have at least one layer of aluminum film stretched over it, and in normal use, a single layer of aluminum film provides sufficient insulation, but for example, in cold regions such as Hokkaido, or when it is necessary to further increase the degree of insulation, use multiple sheets of aluminum film, specifically about 2 to 6 sheets, stretched so as to form an air layer between the other films. It is preferable to hand it over.

In this way, by stretching a plurality of aluminum films with an air layer in between, the air layer acts as a heat insulating layer, and the heat insulating effect is dramatically improved.

There is no particular restriction on the method of stretching the aluminum film, and it can be stretched in accordance with a conventional method. In particular, heat-fusible adhesive is placed in advance on at least the portions of the inner surfaces 5 of the plate-like members A and C where the aluminum film is to be bonded (preferably the entire inner surface of the plate-like members A and C), and the adhesive portion 6 of the aluminum film Q is bonded. It is preferable to use a method of heat-pressing. At this time, a heat-fusible adhesive is attached to at least the adhesive part 6 of the aluminum film,
Adhesiveness is further improved by arranging an aluminum film so that this adhesive and the adhesive disposed on the plate member face each other and bonding them under heat and pressure. In addition, by using an aluminum film in which aluminum is vapor-deposited on a resin film having thermal adhesive properties as described above, the aluminum film has good strength and also has adhesive properties.
It is preferable that there is no need to separately apply a heat-fusible adhesive, and the workability of attaching the aluminum film is improved.

Examples of aluminum films include aluminum foil, aluminum vapor-deposited film in which aluminum is vapor-deposited on synthetic resin film (e.g., polyolefin resin film, heat-adhesive resin film), and laminates of aluminum foil and synthetic resin film (e.g., polyester film). Film/Aluminum foil/
Examples include nylon film/polyethylene film laminate). In particular, when stretching multiple aluminum films, even if multiple sheets of one type of aluminum film are used,
It is also possible to appropriately select and combine different types of films from the above-mentioned films.

The size of the insulating structure, as well as its shape,
It can be set appropriately according to the size of the building. However, considering the rigidity and workability of the heat insulating structure, the lengths of plate members A and C are usually 32 to 70 cm (preferably 38 to 65 cm), and the lengths of plate members B and D are 10~50cm (preferably 15~
45cm), and the width of the plate member is 5 to 15cm (preferably 7cm).
~13cm) is desirable.

Furthermore, when used in a cold region such as Hokkaido, the lengths of plate members A and C should be 32 to 32 cm.
110cm (preferably 38-100cm), the length of plate members B and D is 10-55cm (preferably 15-50cm),
The width of the plate member is 5 to 15 cm (preferably 7 to 13 cm)
In the range of , the insulation effect is dramatically improved by stretching 2 to 6 aluminum films.

The heat insulating structure described above is used in the following manner to form the heat insulating wall of the present invention.

FIG. 2 is a perspective view schematically showing one embodiment of the heat insulating wall of the present invention.

In the heat insulating wall body of the present invention, two or more of the above heat insulating structures are arranged in parallel in each of the vertical and horizontal directions along the cross section of the structure.

The heat insulating wall body of the present invention can have a structure in which two or more heat insulating structures are simply arranged vertically and horizontally along the cross section of the structure, but It is preferable that the wall surface to be installed is first divided into a size that allows insertion of one or more of the above-described heat-insulating structures, and the heat-insulating structures are inserted into the partitioned portions.

That is, by combining the partitioning members 11, such as wood, for example, the heat insulating surface of the wall is partitioned into a size that allows at least one heat insulating structure 12 to be inserted into the partitioned portion.

Note that the object of the present invention can also be sufficiently achieved by partitioning the partitions so that two or more wall heat-insulating structures 12 can be inserted therein. It is particularly preferable to divide the entire heat-insulating surface of the wall into sections having a size that allows one structure 12 to be inserted therein. By dividing the wall so that one section is large enough to insert one heat-insulating structure, it is not only possible to attach the heat-insulating structure easily, but also to
The strength of the building itself is also increased, which is preferable.

The heat insulating structure 12 is housed in a partitioned portion (accommodation portion) of the wall partitioned by the partitioning member 11 in this manner.

It is advantageous to use a collapsible heat-insulating structure, in particular, because it does not take up too much space when storing and transporting the heat-insulating structure before construction.

FIG. 1-a is a perspective view showing the heat insulating structure shown in FIG. 1 in a folded state.

FIG. 1-b is a perspective view showing the state when the heat insulating structure shown in FIG. 1 is folded.

When using the heat insulating structure of the present invention,
Push plate members B and D in the direction of the arrow shown in Figure 1-b to form a frame body with a rectangular (or square) internal cross section as shown in Figure 1. , so that a tensioned aluminum film is stretched over the entire interior of the frame. That is,
The heat insulating structure is in a folded state such that the plate members A and C are in contact with each other as shown in FIG. 1-a until just before use, and is assembled as described above.

The heat insulating structure assembled in this way is
Inserted (accommodated) into the compartment of a building. Generally, building structures are constructed with standardized dimensions, so insulating structures are manufactured to meet these standards.
If the wall surface is divided according to the heat insulating structures, the heat insulating structures can be arranged side by side on the wall surface without gaps.

It is also possible to construct a separate frame for installing the heat-insulating structures in parallel, insert the heat-insulating structures into this frame to form a panel-like body, and then attach the panel-like body to a wall surface, etc. It is.

The heat insulating structures 12 arranged in parallel are the partition members 11
Alternatively, although it is not necessary to engage the adjacent heat insulating structure, it is also possible to engage with the adjacent heat insulating structure using an adhesive tape or an engagement tool (not shown), if desired.

In this way, the heat insulating structure is
Alternatively, an exterior material (not shown) is attached to the surface of walls or the like that are lined up without intervening.

The thermally insulating wall of the building of the present invention is easy to construct and exhibits good thermal insulation properties.

The structure of the present invention can be applied not only to walls but also to floors, ceilings, etc. Therefore, the wall in the present invention refers to only ordinary walls (outer walls and inner walls). Rather, it includes all structures such as floors and ceilings that have the function of dividing space in a building. Moreover, the wall body of the present invention can also be used in combination with other heat insulating materials.

[Effects of the Invention] The heat-insulating wall of the present invention has a heat-insulating effect equivalent to that of a heat-insulating wall made of aluminum film, and is easy to manufacture.

Furthermore, by using the insulating structure of the present invention, it can be assembled and used immediately during construction, and unlike conventional insulating structures, it does not take up excessive space during storage and transportation before construction. There is no problem, and the workability is good.
