BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating panel used for a building in which air is circulated by communicating an underfloor space and an attic space of a building through an air passage provided in an outer wall portion.
[0002]
[Prior art]
Conventionally, as one method for adjusting the temperature inside a building to a comfortable temperature, the underfloor space of the building and the attic space are communicated with each other through a communication passage provided inside the outer wall portion, and air such as warm air and cold air is supplied. By circulating, there is a method of circulating these airs in the under floor portion, the communication path, and the attic space.
[0003]
In this structure, in order to insulate the inside of the building from the outside air, it is necessary to install a heat insulating panel inside the outer wall portion. However, as shown in FIG. The heat insulation panel 110 in which the recessed part 113 was provided in the surface of the heat insulation layer 111 made from is used. When installing this panel, as shown in FIG. 18 (b), if the surface provided with the recess 113 is in contact with the structural column 121, even if the structural column 121 exists, The air can flow through the recess 113 and does not hinder the air circulation.
[0004]
As a method for constructing such a heat insulating panel 110 at a corner of a building, the following method has been adopted.
[0005]
(1) As shown in FIGS. 19 (a) and 19 (b), the corners of the heat insulating panel 110 are cut obliquely to form the cut surface 110a, and the inner wall board 132 is formed as shown in FIG. 20 (a). Two heat insulation panels 110 are attached to the two side surfaces of the structural column 121 installed outside the corner portions 132. At this time, the surface on which the recess 113 is provided and the structural column 121 are brought into contact with each other, and the cut surfaces 110a of the heat insulating panels 110 and 110 are brought into contact with each other. Thereafter, as shown in FIG. 20B, the outer wall material 131 is attached to the outside of the heat insulating panel 110. An air circulation communication path 150 is formed in the gap between the inner wall board 132 and the heat insulation panel 110.
[0006]
(2) As shown in FIG. 21A, by cutting the heat insulating panel 110 and attaching the corner heat insulating panel 115 having a width smaller than that of the heat insulating panel 110 to the structural column 121, The two sides of the column 121 are covered with the heat insulation panel 110 and the corner heat insulation panel 115. Thereafter, as in the construction method (1), the outer wall material 131 is attached to the outside of the heat insulating panel 110. In addition, in order to maintain the heat insulating performance in the corner portion, the concave portion 117 of the corner heat insulating panel 115 is filled with a filler such as urethane.
[0007]
(3) A corner heat insulating panel in which a ventilation groove b is formed on the inner side surface of a heat insulating material a having an L-shaped cross section as shown in FIG. 22 (see Patent Document 1) is installed at a corner portion of a building. .

[Problems to be solved by the invention]
However, when the construction methods (1) and (2) are used, the recesses 113 and 117 are made continuous at the connecting portions between the heat insulation panels 110 or between the heat insulation panels 110 and the corner heat insulation panel 115. Is extremely difficult, and when communicating the communication paths 151 adjacent to the corner portions with the recesses 113 and 117, it is necessary to take considerable effort at the work site.
[0010]
Moreover, when installing the heat insulation panel a as described in said construction method (3) in a building, when conveying to a building site, the shape of the said heat insulation panel a is bulky because it is an L-shaped cross section. In particular, when transporting a plurality of the above heat insulation panels, the space formed when the heat insulation panels are overlapped is large, and the influence of a decrease in transport efficiency is great.
[0011]
Therefore, this invention provides the heat insulation panel for corners installed in the corner part of a building, Comprising: The thing which improved the conveyance efficiency, reducing the effort at the time of construction is provided.
[0012]
[Means for Solving the Problems]
  The present invention is a heat insulating panel for a corner that covers at least two side surfaces of a corner portion of a building, and includes at least two heat insulating units made of foamable synthetic resin and a bonding material for bonding the heat insulating units to each other.

By switching the contact surfaces, the contact surfaces are separated from each other to be substantially flat, and the contact state is brought into contact with each other so that the contact surfaces are in contact with each other to be bent to cover the corner portion. It joins so that it becomes possible, and it is constituted so that the crevice formed in each heat insulation unit may continue in the state where the above-mentioned contact surfaces are in contact.The concave portion further has an intersecting portion that intersects the first concave portion and the second concave portion at a portion where the heat insulating units are in contact with each other.Is.
[0013]
  The present invention also providesHow to install thermal insulation panels for corners of buildingsBecause,A process for producing the heat insulating panel for the corner;A step of separating the contact surfaces of the heat insulating panel for corners and conveying the entire panel in a substantially flat state, and a state in which the entire heat insulating panel is bent by bringing the contact surfaces into contact with each other. Installing the panel so that the thermal insulation panel covers two sides of the corner portion of the building.Is a thing.
[0014]
Therefore, when transporting the heat insulating panel for corners, the entire panel can be substantially planar, so there is little gap between the heat insulating panels even when the heat insulating panels are stacked, Compared with the prior art, the conveyance efficiency is improved.
[0015]
Further, when installing the corner heat insulation panel at the corner of the building at the work site, the corner heat insulation panel is bent around the butted portion of the heat insulation units, and the contact surfaces are brought into contact with each other. Thus, the recesses formed in the mutual heat insulation units can be made continuous by simply bending the entire heat insulation panel. Therefore, unlike the conventional construction methods {circle around (1)} and {circle around (2)}, it does not take time to continue the concave portions located at the corner portions at the work site.
[0016]
  In addition, the corner insulation panel as described aboveThe concave portion includes a first concave portion extending substantially linearly in a right oblique direction when viewed from the inner surface side, and a second concave portion extending substantially linearly in a left oblique direction and intersecting the first concave portion. Therefore, it is preferable in improving the air circulation state. In such a recess,Conventional construction method1as well as2If the position of the heat insulation panel is taken, the vertical position of the recesses will be shifted depending on the position at which the heat insulation panel cuts, and it will be particularly difficult to connect the recessesThe present inventionEspecially effectiveInThe In such a heat insulating panel for corners, the direction of the concave portion has both a horizontal component and a vertical component, so that the circulation is ensured while ensuring the function of communicating the communication passages in the horizontal direction. Air can smoothly flow in the vertical direction, and higher air conditioning is ensured.
[0017]
  The concave portion further includes an intersecting portion that intersects the first concave portion and the second concave portion at a portion where the heat insulating units are in contact with each other.Have. Moreover, this intersection may have a shape extending in the vertical direction.
[0018]
According to a fourth aspect of the heat insulating panel for corners, the concave portion and the contact surface are formed by removing the surface of the heat insulating unit.

  As a method of manufacturing such a heat insulating panel for corners, a foamable synthetic resin is molded into a plate shape as described in claim 5.DoA step, a step of forming a recess by removing the surface of the foamable synthetic resin molded into the plate shape, a step of forming the contact surface and the heat insulating unit by cutting the heat insulating material, Each insulation unitThe sides of the contact surfaceAnd joining the bonding material to the butted portion so as to be bendable around the butted portion. In the step of joining the joining material, the contact surfaces of the heat insulating units are Concave parts formed in mutual heat insulation units when contactedSo that one side of each heat insulation unitYou can take the method.
[0020]
In this regard, in the heat insulating panel for a corner as described in the prior art (3), the synthetic resin is injected into a mold in which a recess is formed in advance, and the synthetic resin is foamed in the mold. It is necessary to manufacture by a molding method. In this case, the expansion ratio of the portion where the recess is formed varies, and stable heat insulation performance cannot be ensured.
[0021]
On the other hand, in the present invention, the corner heat insulating panel is formed by molding the foamable synthetic resin into a plate shape, and removing the surface of the foamable synthetic resin molded into the plate shape so that the concave portion and the contact surface are formed. Therefore, the situation where the expansion ratio is lowered as in the conventional case is prevented, and the heat insulation performance is prevented from being lowered.
[0022]

Match. And the heat insulation panel 10 for corners of FIG. 1 is created by bonding the adhesive tape 12 to the outer side surface 11c of the heat insulation unit 11, and joining the said butt | matching part. The pressure-sensitive adhesive tape 12 is such that the heat insulating unit 11 can be bent around its abutting portion, and the concave portions 13 formed in the heat insulating units 11 are continuous when the contact surfaces 11a come into contact with each other. Bond in such a state.
[0036]
The structure of a building using such a heat insulating panel 11 for corners is shown in FIG. FIG. 11 is a cross-sectional view of the wall structure in the vicinity of the corner portion of the air circulation building according to the present embodiment from above. In this building, a plurality of structural columns 121 that support the entire structure are installed at intervals. In the figure, only the structural pillar 121 installed at the corner is shown.
[0037]
Then, the heat insulating panel 110 and the corner heat insulating panel 10 are installed in close contact with the outer surface of the structural column 121. Further, the ventilator edge 116 is installed on the outer side, and the outer wall member 131 is installed on the outer side. ing. An inner wall board 132 is installed inside the structural pillar 121 and faces the inside (inside the room) of the building.
[0038]
The corner heat insulating panel 10 and the structural column 121 are fixed by installing a ventilator edge 116 on the outer side of the corner heat insulating panel 10 and penetrating screws 141 from the outer side. Although not shown, the heat insulation panel 110 and the structural pillar 121 are fixed by installing a ventilator edge 116 on the outside of the heat insulation panel 110 and inserting a screw 141 from the outside. Further, the fixing of the outer wall member 131 to the heat insulating panel 110 and the corner heat insulating panel 11 is also performed by inserting a screw 141.
[0039]
According to such a structure, a gap serving as the communication path 150 is formed in a portion surrounded by the inner wall board 132 of the structural column 121 and the heat insulating panel 110. Although not shown, the communication path 150 communicates with a space configured in the attic portion and a space configured in the underfloor portion, and air such as cold air or warm air produced by an air conditioner installed in the underfloor portion, It flows and circulates to the attic. The cold air or warm air flows in the communication passage 150, whereby the heat of the cold air or warm air is transferred to the inside of the building through the inner wall board 132, and the inside of the building is adjusted to a comfortable temperature. It should be noted that moisture or the like existing between the inner wall board 132 and the outer wall member 131 is formed in a gap between the outer wall member 131 and the heat insulating panel 110 and communicated with the outside air (not shown). It is discharged to the outside air through the air passage 151.
[0040]
Further, as shown in FIG. 12, the recesses 13 and 113 are configured to communicate with the outer surface of the structural column 21, and the adjacent communication paths 50 communicate with each other through the recesses 13 and 113.
[0041]
Next, a method for constructing the building using the heat insulating panel 10 for corners will be described with reference to FIGS.
[0042]
Process {circle around (1)} (see FIG. 13A): The heat insulating panel for corner 10 is transported to the work site. At this time, the corner heat insulating panel 10 is in a state where the contact surfaces 11a are separated from each other so that the whole corner heat insulating panel 10 is substantially flat, and a plurality of such corner heat insulating panels 10 are stacked. Transport.
[0043]
Step (2) (see FIGS. 13B and 13C): At the work site, the heat insulating panel 10 for the corner, which is generally flat as shown in FIG. The contact surfaces 11a formed on the heat insulating unit 11 are brought into contact with each other as shown in FIG.
[0044]
Process {circle over (3)} (see FIG. 11): In a building in which the inner wall board 132 and the structural pillar 121 are installed in advance, the corner heat insulating panel is provided on the two side surfaces which are the outer surfaces of the structural pillar 121 located in the corner portion. 10 is installed so that its inner surface contacts. The structural pillar 121 is provided with a heat insulating panel 110 except for the corner portion. When the corner heat insulating panel 10 is installed at the corner portion, the concave portion 13 and the concave portion 113 are formed as shown in FIG. It arrange | positions so that it may continue, and the adjacent communication paths 150 communicate with each other through the recessed parts 13 and 113. Then, the ventilation trunk edge 116 is installed outside the heat insulating panel 10 for the corner and the heat insulating panel 110, and the heat insulating panel 110 and the heat insulating panel 10 for the corner are inserted by penetrating the screw 141 from the outside to the structural column 121. The structural column 121 is fixed. And the outer wall material 131 is installed, and the heat insulation panel 110 and the heat insulation panel 10 for corners, and the outer wall material 131 are fixed by penetrating the screw 141 from the outside.
[0045]
When such a corner heat insulation panel 10 is used, when transporting to a work site, the corner heat insulation panel 10 is in a state of being substantially planar, and thus a plurality of corner heat insulation panels 10 are laminated. However, since there are few gaps between the said heat insulation panels 10 for corners, conveyance efficiency improves compared with a prior art.
[0046]
Furthermore, when installing the heat insulation panel 10 for corners in the corner part of a building at a work site, the abutting part (the outermost surface side of the contact surfaces 11a) of the heat insulation units 11 of the heat insulation panel 10 for corners. It is formed in the mutual heat insulating unit 11 only by bending the contact sides 11a to each other and bending the entire heat insulating panel 10 for the corners by bending the center of the adjacent sides 11b and 11b). The recessed part 13 made can be made continuous. Then, just by installing the corner heat insulation panel in such a state at the corner portion of the structural column 121, as shown in FIG. 12, the concave portion 13 and the concave portion 113 are arranged so as to be continuous, and the adjacent communication passages 150 are connected to each other. The recesses 13 and 113 communicate with each other. Therefore, unlike the conventional construction methods {circle around (1)} and {circle around (2)}, it does not take time to continue the concave portions located at the corner portions at the work site.
[0047]
Therefore, if this corner heat insulation panel 10 is used, the trouble at the time of construction in the corner part of a building can be reduced, and further, the efficiency of transporting the corner heat insulation panel 10 to the work site is also improved. I can do it.
[0048]
In addition, making the heat insulating panel 110 as described above is particularly effective in a shape in which the concave portions 13 and 113 are formed so as to extend substantially linearly in an oblique direction. This is because when the conventional construction methods {circle around (1)} and {circle around (2)} are adopted, the vertical positions of the concave portions are shifted depending on the position at which the heat insulating panel is cut, and it is particularly difficult to connect the concave portions. Since the recesses 13 and 113 are formed so as to extend substantially linearly in an oblique direction, the recesses 13 and 113 have both a horizontal component and a vertical component, and the communication paths 150 are connected to each other. It is possible to smoothly flow the circulating air in the vertical direction while ensuring the function of communicating with the horizontal direction, and to ensure higher air conditioning.
[0049]
Further, the recesses 13 and 113 are formed so as to extend substantially linearly in the upward direction when viewed from the inner surface of the heat insulation panel, and extend substantially linearly in the upward direction. Since the recessed portions 13 and 113 are formed so as to intersect with each other, air can be circulated in more directions than in the case where the recessed portion 13 is formed so as to extend only in either the left or right direction. The possibility of hindering air circulation can be further reduced, and the air circulation state can be further improved.
[0050]
Moreover, since the heat insulation panel 11 for corners is formed by removing the surface of the said heat insulation unit, the recessed part 13 and the contact surface 11a are formed in the metal mold | die in which the recessed part was previously formed like the past. As in the case of manufacturing by a method in which a resin is injected and the synthetic resin is foamed and molded in a mold, a situation in which the expansion ratio of the portion where the concave portion is formed does not decrease does not occur. Therefore, it becomes possible to improve heat insulation performance conventionally.
[0051]
Other embodiments
1) As shown in FIG. 15, the shape of the concave portion 13 is such that the contact surfaces 11a of the heat insulating units 11 are brought into contact with each other, and when the heat insulating units 11 are brought into contact with each other, You may provide the crossing part 13a which cross | intersects the X-shape in the part which the recessed part 13 extended in the left upward direction contact | abutted. FIG. 14 shows a state in which the contact surfaces 11a of the heat insulating unit 11 are separated from each other in the corner heat insulating panel 10 of FIG.
[0052]
2) The intersection 13a is not limited to the X shape as described above. For example, as shown in FIGS. 16 and 17, the length direction (vertical direction in FIGS. 16 and 17). ) May be extended to the shape.
[0053]
3) Insulation between the heat insulating units 11 is performed by using, for example, a sheet made of a material such as a nonwoven fabric or a synthetic resin, instead of bonding the adhesive tape 12 to the heat insulating unit 11, and is bonded to at least the sheet or the heat insulating unit 11. A material may be applied to adhere the sheet to the heat insulating unit 11. In addition, as an example of this sheet | seat, the thing made from the nonwoven fabric provided with waterproofness, a windproof property, and moisture permeability is mentioned. When the heat insulating panel 10 to which this sheet is bonded is installed in a building, moisture existing inside the building is discharged to the outside from this sheet, and the entry of wind and moisture from the outside of the building is reduced from this sheet. It becomes possible.
[0054]
【The invention's effect】
As described above, according to the present invention, since the corner heat-insulating panel can be substantially flat in the transport state, the heat-insulating panel can be used even when the heat-insulating panels are stacked. There are few gaps between them, and the conveyance efficiency can be improved as compared with the prior art.
[0055]
Furthermore, when installing the heat insulation panel at the corner of the building at the work site, the heat insulation panel is bent around the abutting portion between the heat insulation units, and the contact surfaces are brought into contact with each other so as to contact the heat insulation panel. The concave portions formed in the mutual heat insulating units can be continued only by setting the whole to bend. Therefore, if this heat insulating panel for a corner is used, it is possible to reduce the labor for construction in the corner portion of the building, and it is possible to improve the efficiency of transporting this panel to the work site.
[0056]
  The concave portion includes a first concave portion extending substantially linearly in a right oblique direction when viewed from the inner surface side, and a second concave portion extending substantially linearly in a left oblique direction and intersecting the first concave portion. Therefore, it is preferable in improving the air circulation state.
