Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel of a building which is particularly effective for forming an outer heat insulating of the building.

[0002]

2. Description of the Related Art The revised Energy Conservation Law requires not only improving the heat insulating property of a building but also ensuring airtightness. Particularly in cold regions, it is important to improve the heat insulation and airtightness of buildings. At that time, if the heat insulating layer and the airtight moisture-proof layer are misplaced, dew condensation will occur in the wall, and the durability of the building will be significantly reduced. In order to prevent this, it is necessary to continuously provide an airtight and moisture-proof layer on the indoor side of the outer peripheral wall and continuously provide a heat insulating layer on the outer side thereof.

For example, FIG. 10 shows an example in which only the heat insulating layer (1) is provided between the exterior material (2) and the interior base material (3) without providing the airtight layer. The water vapor that has permeated 1) comes into contact with the low temperature part outside the heat insulating layer (1) to cause dew condensation. Further, in FIG. 11, an airtight moisture-proof layer (4) is provided outside the heat insulating layer (1) and a ventilation layer (5) is provided between them (1) and (4). It is unavoidable to pass through the layer (1) and go out to the outside, and even if condensation can be somewhat reduced by diffusing and diluting in the aeration layer (5), if the amount of water vapor is large, the airtight moisture-proof layer (4) Condensation will occur inside the. On the other hand, FIG. 12 shows that the airtight moisture-proof layer (4) is arranged inside the heat-insulating layer (1), whereby the moist air on the indoor side is blocked inside the airtight moisture-proof layer (4). Even if it permeates through the gap of the moisture-proof layer (4) or the like, since the amount is small, it is possible to prevent it from being diffused and diluted by the outer ventilation layer (5) to cause dew condensation.

That is, in terms of the relationship between the heat insulating layer (1) and the airtight moistureproof layer (4), it is desirable to dispose the airtight moistureproof layer (4) inside the heat insulating layer (1).

On the other hand, regarding the arrangement of the heat insulating layer (1), as shown in FIG. 13, the inner heat insulating construction method in which the heat insulating layer (1) is arranged inside the structural body (6), and the structure shown in FIG. There is an external heat insulation construction method that is placed inside the body (6). In this case, in the internal heat insulation, the airtight moisture-proof layer (4) is naturally provided on the inner wall portion inside the heat insulation layer (1) from the above point. 10 to 12, the heat insulating layer (1) is provided inside the structural body, but this is also a wide sense of internal heat insulating.

[0006] Comparing the outer insulation with the inner insulation, the outer insulation is more advantageous in the cold region where constant heating is required because the heat storage capacity of the structural body can be utilized. Furthermore,
In the internal heat insulating structure, as shown in FIG. 13, since many openings such as a downlight opening (7) from the ceiling, a large number of outlet openings (8), and an electric switch opening (9) are formed, This opening easily impairs the continuity of the heat insulating layer (1) and the airtight moisture-proof layer (4), and from this point, it can be said that the outer heat insulating is excellent.

[0007]

However, even in external heat insulation, even though the above-mentioned opening is not present and the number of defects in the heat insulation layer is small, heat insulation construction is performed using a heat insulation panel made of hard foam synthetic resin or the like. When this is done, because the heat insulation panel is hard, there is a gap between the window eaves (11) and the arm timber (12) such as the window handrail (10) as shown in FIG. This is apt to occur, and for this reason, there is a problem that it is necessary to repair the clearance between the panels. On the other hand, even in the airtight layer, it is necessary to carry out airtight repair by taping or caulking with an asphalt adhesive tape. However, heat insulation repair and airtight repair require precise construction and much labor. In addition, a high level of skill is required for on-site construction for heat insulation and airtightness, and the technical level at the site affects building performance. On the other hand, it is the current situation that almost no heat insulating and airtight construction methods are available by industrial methods that do not require special skills.

The present invention has been made for the purpose of providing a novel heat insulating panel which is excellent in heat insulating property and airtightness and has good workability without requiring precise work and much labor.

[0009]

In order to solve the above-mentioned problems, the heat insulating panel of the present invention has a pair of split members obtained by splitting one heat insulating panel into two and connecting them in a mutually bendable manner. , Characterized in that an airtight material is attached to an end surface of each division member extending in a direction perpendicular to the bending line, and a curl prevention tape is attached to extend from the outer surface of the airtight material to the side surface of the division panel. And

In the above-mentioned invention of claim 2 of the present application, the central portion in the width direction of the outer surface of the airtight material is exposed more than the curl prevention tape and bulges outward.

As the heat insulating panel of the present invention, a hard foam synthetic resin material such as a hard urethane foam can be considered. Further, the heat insulation panel of the present invention is not limited to the outer wall of the building,
It can be used for roof (ceiling), alcove eaves, and their joints, outer wall and foundation, and so on.

[0012]

The heat insulating panel composed of the divided members connected to each other is mounted by pushing them in a state in which they are bent in a dogleg shape. In this case, if there is another heat insulating panel or arm lumber adjacent to the split member end face side extending in the direction perpendicular to the bending line, the airtight member of the panel end face and the airtight member of the pushed panel end face mutually. The end faces of the panel come into close contact with each other in a compressed state.

Further, in this case, when the airtight material portion is pushed, there is a possibility that the airtight material portion may be rubbed with another member such as an adjacent airtight material portion or an armrest to be displaced and peeled off. It is well-cured, and it stays in a regular position while maintaining elasticity, ensuring airtightness.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the steps from production to installation of a heat insulating panel when the present invention is applied to the outer wall of a building will be described in order.

In FIG. 1, (21) and (21) are rectangular split members of the same shape, which are made of a hard foam synthetic resin material having heat insulating performance, such as foam polystyrene or hard urethane foam. . And these division | segmentation members (21) (21) match | combine these division | segmentation edge parts mutually, and adhere the connecting tape (22) so that it may straddle between the division | segmentation edge parts, and it may be the same as before division. It forms a rectangular insulation panel (23) of one shape. As a result, each of the division panels (21) (21) has the tape (23) as a fulcrum with respect to the vertical folding line (24) as a division line.
Can be bent to each other to at least a dogleg shape. As the tape (22), a tape having airtightness and moisture resistance is used.

Next, the divided members (21) connected to each other.
As shown in FIG. 2, strip-shaped hermetic packings (25) and (26) each having a required thickness are provided on the upper and lower end surfaces and the end surface on the opposite side to the end surface on the split side, as shown in FIG. ) Is attached so as to cover the entire circumference. The airtight packings (25) (26) are made of an airtight material having flexibility such that they are easily compressed and having low moisture permeability. For example, an independent foam sponge material such as EPT SEALER (trademark) is used. Etc. are used. The width thereof is the same as the thickness of the split members (21) (21). Further, as shown in FIG. 8, at the outer corner portions of the airtight packing (25) on both the upper and lower end surfaces, the outer surface of the upper or lower part of the airtight packing (25) extends over the side surface of the split member (21). The anti-roll-up tape (27) is attached to each other so as not to cause slipping or peeling by rubbing with the heat insulating panel (23) or the arm member adjacent to the upper side or the lower side. At that time, each anti-rolling tape (27)
Both sides in the width direction of the outer surface of the airtight packing (25) to which (27) is bonded are pressed by the tape (27) to be lowered. As a result, the central portion (28) of the outer surface, which is not pressed by the tape (27), relatively bulges outward.

The airtight packing (25) (2
The heat-insulating panel (23) to which 6) is attached is bent in a V shape toward the surface side as shown in FIG. 3, and is turned upside down in the direction of the arrow, and then the tape (23) is attached as shown in FIG. Is attached by pushing in from the opposite surface, so that the end surface of the split panel (21) opposite to the connecting portion projects from the end surface of the adjacent heat insulating panel (22) or the structural frame as shown in the figure. Airtightly adhere to the outer peripheral surface of each arm member (29). Furthermore, the heat insulation panels (22) adjacent to each other in the vertical direction of the figure
If there is such a thing, the airtight packing (25) part is pushed by rubbing against the end surface of the adjacent member at the time of this pushing, but since it is cured by the curl prevention tape (27) as described above, It can be placed in the proper position without any displacement or peeling. Then, as shown in FIG. 9, the airtight packing (25) is compressed by contacting the airtight packing (25) with the bulging portion (28) at the center of the outer surface, or like another armpiece. Even if there is an object, it is deformed flexibly along its outer shape, so that almost no gap is generated and reliable airtightness can be secured.

That is, such a curl prevention tape (27)
If there is not, and you push in from the state shown in Fig. 15,
As shown in FIG. 6, when pushed, one or both of the airtight packings (25) are rolled up, but the tape (27) prevents the airtight packings (25) from peeling off each other as shown in FIG. That is, the bulging part of will enter while compressing.

[0019]

As described above, according to the present invention, the pair of divided members are pushed into each other from the state of being bent in the shape of a dogleg to the shape of a flat plate to be attached to the heat insulating panel. The effect is that it can be attached closely to and without any gaps.

In particular, according to the present invention, if there is another heat insulating panel, armor or the like adjacent to the end surface side of the dividing member extending in the direction perpendicular to the bending line, the airtight material of the pushed panel end surface is compressed. In this state, the end faces of the panel are in close contact with each other, and since the airtight material is cured by the curl prevention tape, it can be securely placed in the proper position without peeling or curling.

Further, according to the invention of claim 2 of this application, not only is it cured by the anti-bending tape as described above, but also the central portion of the airtight material is exposed to the outside in a bulging manner. There is an effect that the airtightness can be more surely maintained by firmly adhering to the airtight material while being compressed.
