BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating panel used for a roof portion of a building and a heat insulating structure using the panel.
[0002]
[Prior art]
Conventionally, as a means for improving the heat insulation performance of the roof portion of a building, for example, a heat insulation structure as shown in FIG. 3 (see FIG. 4 of Patent Document 1) is known. In this heat insulating structure, a heat insulating panel 100 is fitted between shaft members 121 such as rafters. The heat insulating panel 100 is formed in a structure in which the heat insulating plate 111 and the face material 101 are integrated, and a portion of the heat insulating plate 111 is fitted between the shaft members 121. Further, a notch 113 is provided in each of the portions near one end of one side of the heat insulating plate 111, and the notch 113 is elastically deformable. Therefore, even if the spacing between the shaft members 121 and the size of the heat insulating plate 111 vary, the heat insulating material 111 can be reliably fitted between the shaft members 121. Further, when the heat insulating plate 111 is fitted between the shaft members 121, the notch 113 can be elastically deformed and fitted, so that such an operation can be easily performed.

[Problems to be solved by the invention]
In the above structure, by forming the notch 113, the bending rigidity is lowered, and the heat insulating plate 111 installed in the building is likely to be bent and deformed. Such a decrease in bending rigidity is intended to increase the amount of dimensional adjustment. Increasing the number of notches 113 becomes more prominent. Therefore, when the heat insulating plate 111 is installed between the shaft members 121 of the roof portion, there is a possibility that the intermediate portion in the width direction of the heat insulating plate 111 may bend and bend. Further, when the heat insulating plate 111 is fitted between the shaft members 121, the heat insulating plate 111 may be cracked from the notch 113.
[0005]
Therefore, the present invention is a heat insulating panel that can be installed by absorbing the dimensional error even if a dimensional error occurs between the shaft members or the heat insulating panel, and can also ensure high heat insulating properties and sufficient bending rigidity. Is to provide.
[0006]
[Means for Solving the Problems]
The present invention is a heat insulating panel that is fitted between shaft members of a building roof portion, and the heat insulating panel is interposed between the heat insulating plate and the heat insulating plate and the shaft member. A pair of end members that are respectively attached to the end portions of the heat insulating plate, and the heat insulating panel is mounted on the shaft member on both front and back surfaces of the end portions of the heat insulating plates to which the end members are attached. A plurality of notches extending in a direction substantially perpendicular to the direction of the plurality of notches are formed side by side in a direction perpendicular to the longitudinal direction, and the end member is a heat insulating plate into which an end of the heat insulating plate in which the notches are formed is fitted And a shaft member contact portion that press-contacts the shaft member when the heat insulating panel is fitted between the shaft members, and the heat insulating plate insertion portion is an end of the heat insulating plate to be inserted into the shaft member contact portion. Of the end abutment surface that abuts the end surface of the part and the end of the heat insulating plate Also it has a holding surface for holding a portion of said notch is provided from the front and rear sides, and has a shape that holding the end of the insulating plate in a region including all of these notches The overall size of the heat insulation panel is increased or decreased in the width direction of the notch by elastically deforming the heat insulating plate so that the width of the notch varies in the fitted state.
[0007]
As the heat insulation structure of the building roof part using this heat insulation panel, as in claim 3 , the heat insulation panel is a heat insulation structure fitted between the shaft members of the building roof part,
The pair of end members are respectively fitted in both end portions of the heat insulating plate of the heat insulating panel in a state of completely covering the notch of the heat insulating plate with the heat insulating plate insertion portion of the end member,
It is possible to adopt a structure in which the heat insulating panel is fitted between the shaft members in a state where the shaft contact portions of the end members are in pressure contact with the shaft members.
[0008]
If this heat insulation panel is used, the said heat insulation board will elastically deform so that the width | variety of the notch formed in the front and back of the said heat insulation board may become narrow by applying compressive force from the both-ends side. Therefore, the dimension in the width direction of the heat insulating plate is increased or decreased, and the dimension in the width direction of the heat insulating panel can be adjusted. Therefore, even if a dimensional error between the shaft members or the heat insulating panel occurs, the heat insulating panel can be reliably fitted between the shaft members.
[0009]
Furthermore, since the heat insulating plate is inserted in a state in which the notch is completely covered and the front and back of the heat insulating plate are sandwiched between the holding surfaces, the notch portion is It is possible to suppress a decrease in bending rigidity due to being provided. Therefore, it becomes possible to make the heat insulating panel installed on the roof portion difficult to bend and deform while having a dimension absorbing function by forming the notches. Moreover, at the time of installation of a heat insulation panel, a heat insulation board (especially the part in which the notch was formed) can be effectively protected by an end member. In particular, when a plurality of notches are formed in the heat insulating plate, sufficient bending rigidity can be maintained by sandwiching the notch forming region with the end member while increasing the dimensional absorption amount. Furthermore, a plurality of notches are formed on both the front and back surfaces of the end portion of the heat insulating plate in a direction perpendicular to the longitudinal direction, and the end portion of the heat insulating plate is sandwiched in a region including all these notches. Since the shape of the heat insulating plate insertion portion is set as described above, it is high by holding the portions where these notches are formed while increasing the adjustable dimensions by forming a plurality of notches side by side. Bending rigidity can be maintained.
[0010]
It is possible to absorb the dimension by providing a gap between the end face of the heat insulating plate and the inner surface of the heat insulating plate insertion portion, and adjusting the size of the gap. In the present invention, the heat insulation performance is lowered due to the presence of the gap, whereas in the present invention, the end surface and the end contact surface come into contact with each other so that a gap is not generated between the members as much as possible. Since the dimension is absorbed by the elastic deformation of the material, it is possible to effectively suppress the deterioration of the heat insulation performance due to the gap.
[0011]
According to a second aspect of the present invention, in the state where the end portion of the heat insulating plate is inserted into the heat insulating plate insertion portion, the heat insulating plate insertion portion so that the holding surface is in close contact with both front and back surfaces of the end portion of the heat insulating plate. It is a heat insulation panel in which the shape is set.
[0012]
In the configuration of the heat insulating panel, the sandwiching surfaces are in close contact with both front and back surfaces of the end portion of the heat insulating plate, so that the bending deformation amount of the heat insulating plate can be suppressed and the bending rigidity can be increased.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. However, the present invention is not limited to the following embodiments.
[0014]
FIG. 1 is a cross-sectional view of a roof portion of a building and shows an installation state of a heat insulating panel 1.
[0015]
The roof portion is provided with a roof finishing material 15, waterproof paper 13, field plywood 11, and rafters 21 (shaft members) from the outside of the roof. The rafters 21 are arranged at regular intervals along the roof portion, and the heat insulation panel 1 is inserted between the adjacent rafters 21.
[0016]
Hereinafter, the configuration of the heat insulating panel 1 will be described with reference to FIG. The heat insulating panel 1 includes a heat insulating plate 3 and an end member 7. As the material for the heat insulating plate 3 and the end member 7, a material obtained by foaming a synthetic resin such as polystyrene, urethane, or phenol is mainly used. From the viewpoint of heat insulation, it is more preferable to use foamable phenol. Moreover, when importance is attached to workability, it is more preferable to use polystyrene.
[0017]
The heat insulating plate 3 has a substantially rectangular plate shape. Then, on both the front and back surfaces, a plurality of notches 31 (two surfaces in FIG. 2) are perpendicular to the longitudinal direction at both ends in the direction perpendicular to the longitudinal direction (the front-rear direction of the paper in FIG. 2). These notches 31 are formed side by side and are formed to extend in the longitudinal direction. Further, all the cutouts 31 have the same shape, and are formed at substantially equal intervals alternately on the front and back sides. Note that an aluminum sheet 35 is bonded to the surface of the heat insulating panel 1 (the upper surface in FIG. 2) in order to enhance the heat shielding effect.
[0018]
The end member 7 is formed with a concave heat insulating plate insertion portion 70 into which an end portion of the heat insulating plate 3 is inserted, and a shaft member contact portion 75 that contacts the rafter 21. And the inner side surface of the heat insulation board insertion part 70 is the contact surface 73 which contacts the end surface 33 of the clamping part 71 which clamps the edge part in the state closely_contact | adhered to both the front and back both surfaces of the heat insulation board 3, and the end part 33 It consists of The shaft member contact portion 75 is formed in a shape that is recessed in a substantially L shape so as to be able to contact the upper side surface and the upper surface of the rafter 21.
[0019]
And when the edge part of the heat insulation board 3 is inserted in the end member 7, it is pinched so that the area | region including all the notches 31 among the front and back both surfaces of the heat insulation board 3 edge | part may contact | adhere to the pinching surface 71, And the heat insulation board end surface 33 and the contact surface 73 of the heat insulation board 3 contact | abut. Moreover, when the heat insulation panel 1 in the state in which the end portion of the heat insulating plate 3 is inserted into the end member 7 is inserted between the rafters 21, a compressive force is applied from both side end portions of the heat insulating panel 1 to the heat insulating plate 3. When the compressive force is applied from both side end portions, the width of the notch 31 is narrowed, the heat insulating plate 3 is elastically deformed, and the direction perpendicular to the longitudinal direction of the heat insulating panel 1 (the width of the notch is defined in claim 1). (Direction) is reduced so that it can be inserted between the rafters 21. In addition, since this deformation | transformation is elastic deformation, the dimension of the heat insulation panel 1 can be increased / decreased in the direction orthogonal to the longitudinal direction of the heat insulation panel 1. FIG.
[0020]
Returning to FIG. 1, the continuation will be described. As a situation in which the heat insulating panel 1 is inserted between the rafters 21, a pair of end members 7 attached to both ends of the heat insulating plate 3 include a rafter 21 and a field plywood 11. The shaft member contact portion 75 of the end member 7 is in pressure contact with the rafter 21.
[0021]
Although not shown, in such a state, the notch 31 is in a direction substantially perpendicular to the arrangement direction of the rafters 21 (the left-right direction in FIG. 1), that is, the direction in which the rafters 21 extend (in FIG. It is arrange | positioned in the state extended in the direction substantially equal to the front-back direction.
[0022]
Further, the heat insulating plate 3 is arranged in a state where the aluminum sheet 35 faces the field plywood 11, and a ventilation portion 23 is provided in a portion surrounded by the aluminum sheet 35, the field plywood 11, and the adjacent end members 7. Is formed.
[0023]
When this heat insulating panel 1 is used, the heat insulating plate 3 is elastically deformed so that the width of the notch 31 formed on the front and back of the heat insulating plate 3 is narrowed by applying a compressive force from both side end portions. It is possible to adjust the dimensions of the heat insulation panel 1 in a direction orthogonal to the longitudinal direction. Therefore, even if a dimensional error between the rafters 21 or the heat insulating panel 1 occurs, the heat insulating panel 1 can be reliably fitted between the shaft members.
[0024]
The dimensional error between the rafters 21 includes a dimensional error caused by a slightly different interval between the rafters 21, a side surface of the rafters 21 (portions located at the left and right ends of the rafters 21 in FIG. 1), and the field. There are two types of dimensional errors that occur when the angle formed between the plywoods 11 is slightly deviated from the vertical, but when this thermal insulation panel 1 is used, the thermal insulation panel is surely secured regardless of which dimensional error occurs. 1 can be fitted between the shaft members.
[0025]
Further, the heat insulating plate insertion portion 70 is provided with the notch 31 because the notch 31 is completely covered and the heat insulating plate 3 is fitted in a state where the front and back of the heat insulating plate 3 are held between the holding surfaces 71. It is possible to suppress a decrease in bending rigidity due to the above. Therefore, it becomes possible to make the heat insulating panel 1 installed on the roof portion difficult to bend and deform while having a dimension absorbing function by forming the notch 31. Further, when the heat insulating panel 1 is installed, the heat insulating plate 3 (particularly, the portion where the notch 31 is formed) can be effectively protected by the end member 7. In particular, when a plurality of cutouts 31 are formed in the heat insulating plate 3, sufficient bending rigidity can be maintained by holding the formation region of the cutouts 31 with end members while increasing the amount of dimension absorption.
[0026]
The above-described dimension absorption can also be performed by providing a gap between the end face of the heat insulating plate and the inner surface of the heat insulating plate insertion portion and adjusting the size of the gap. However, when such a structure is adopted, the heat insulating performance is degraded due to the presence of the gap. With respect to such a structure, the heat insulating panel 1 of the present invention has a state in which the heat insulating plate end surface 33 and the contact surface 73 are in contact with each other so that a gap is not generated between the heat insulating plate 3 and the end member 7 as much as possible. Since the dimension is absorbed by the elastic deformation of the notch 31 formation portion, it is possible to effectively suppress the deterioration of the heat insulation performance due to the gap.
[0027]
Further, since the sandwiching surfaces 71 are in close contact with both the front and back surfaces of the end portion of the heat insulating plate 3 with the end portion of the heat insulating plate 3 inserted into the heat insulating plate insertion portion 70, the amount of bending deformation of the heat insulating plate 3 is suppressed. , Bending rigidity can be increased.
[0028]
Furthermore, since a plurality of cutouts 31 are formed on both the front and back surfaces of the end portion of the heat insulating plate 3 in a direction perpendicular to the longitudinal direction, these are adjusted while increasing the adjustable dimensions of the heat insulating panel 1. High bending rigidity can be maintained by holding the portion where the notch 31 is formed.
[0029]
In addition, the notches 31 formed at a plurality of positions arranged in the direction orthogonal to the longitudinal direction on the front and back surfaces of the heat insulating plate 3 are all substantially in the same shape, and are formed in a state where the front and back surfaces are alternately spaced at substantially equal intervals. Therefore, when a compressive force is applied from both end portions of the heat insulating plate 3, the heat insulating panel 1 is compressed in a substantially uniform state, and the dimensions of the heat insulating panel 1 can be adjusted without unevenness.
[0030]
Note that the end portion of the heat insulating plate 3 and the sandwiching surface 71 are not necessarily in close contact with each other. Even in such a case, bending deformation of the heat insulating plate 3 can be suppressed. However, it is more preferable that the end portion of the heat insulating plate 3 and the sandwiching surface 71 are in close contact with each other in order to suppress bending deformation of the heat insulating plate 3.
[0031]
【The invention's effect】
As described above, the heat insulating panel of the present invention includes a heat insulating plate and a pair of end members respectively attached to end portions of the heat insulating plate so as to be interposed between the heat insulating plate and the shaft member. The front and back surfaces of the end portion of the heat insulating plate to which the end member is attached have a plurality of notches extending in a direction substantially orthogonal to the direction in which the shaft members are arranged in a state where the heat insulating panel is mounted on the shaft member. The end member is formed side by side in a direction perpendicular to the direction, and the end member is an insulating plate insertion portion into which an end portion of the insulating plate in which the notch is formed is inserted, and an end surface of the end portion of the insulating plate into which the end member is inserted And an end abutting surface that abuts with each other, and at least a portion of the end portion of the heat insulating plate that is provided with the notch from both the front and back sides, and includes all these notches region has a shape that holding the end of the heat insulating plate, the its The heat insulating plate such that the width of the notch varies with fitted state in which the overall dimensions of the insulating panel is increased or decreased in the width direction of the cut by elastic deformation.
[0032]
As described above, when this heat insulating panel is used, the heat insulating plate is reliably pressed between the shaft members even if a dimensional error occurs between the shaft members or the heat insulating panel by applying a compressive force from both side end portions. Can be fitted. Further, the heat insulating plate insertion portion is formed with the notch because the notch is completely covered and the heat insulating plate is fitted in a state where the front and back of the heat insulating plate are sandwiched between the holding surfaces. Therefore, it is possible to make a structure in which the heat insulating panel installed on the roof portion is difficult to bend and deform while having a dimension absorbing function.
[0033]
Particularly it can increase the dimensions absorption by Rukoto put plurality of notches in the heat insulating plate, moreover, to maintain a sufficient flexural rigidity by holding these formation regions of the cutouts in the end member I can do it.
[0034]
In addition, since the heat insulating plate end surface and the end contact surface are in contact with each other and the gap is not generated as much as possible, the dimension is absorbed by elastic deformation of the notch forming portion. It is possible to effectively suppress a decrease in heat insulation performance due to the gap.
