Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel, and more particularly to a heat insulating panel in which a joining structure between an oblique member of a frame and an intermediate frame member is improved to improve assemblability.

[0002]

2. Description of the Related Art As a building, there is known a wooden building in which a frame is constructed by attaching a wall panel or a roof panel made of a heat insulating panel to a frame constructed by a conventional construction method to form a frame. ing. The heat insulating panel used in this building is composed of a frame, face materials attached to both sides of the frame, and a heat insulating material provided inside the frame and the face material. This heat insulating panel is not only excellent in heat insulating properties, but also becomes a load-bearing wall by using a structural surface material as a surface material, thereby improving the strength of the building.

[0003] By the way, as the heat insulating panel, for example, one frame material constituting the frame is an oblique material, such as a corner panel, and an intermediate frame material (in the case of a roof panel, both timber and wood) is included in the frame. Is provided. In this case, the intermediate frame material must be joined obliquely, not perpendicularly, to the oblique material.
The joining structure becomes a problem.

FIG. 6 is a view showing a joining structure of a diagonal member and an intermediate frame member in a conventional heat insulating panel. In the conventional heat insulating panel, when the intermediate frame member 10 is joined to the diagonal member 6a, the end face 10a of the intermediate frame member 10 is brought into surface contact with the diagonal member 6a. End face 10
a was cut obliquely so as to form an inclined surface having the same angle as that of the oblique member 6a. Further, a screw 20 is used to fix the diagonal member 6a and the intermediate frame member 10, and the screw 20 is screwed in a direction perpendicular to the intermediate frame member 10, that is, in the longitudinal direction of the intermediate frame member 10 to be inclined. The material 6a and the intermediate frame material 10 were joined.

[0005]

However, since the heat insulating panel employs a structure in which the end of the intermediate frame is cut obliquely, the intermediate frame is first cut at a right angle. Next, two cutting steps of oblique cutting are inevitably performed, and it is difficult to obtain the accuracy of the oblique cutting, which is troublesome and increases the processing cost. In addition, since the screw was screwed vertically to the intermediate frame to join the diagonal material and the intermediate goods, the screw had to be screwed diagonally to the diagonal material. It was difficult and time-consuming to assemble.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a heat insulating panel in which processing costs are reduced and assemblability is improved.

[0007]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 3, 1 is a roof of a wooden building, and 2 is an outer wall line of the building. A skeleton is configured by attaching a wall panel (not shown) made of a heat insulating panel and a roof panel 4 to the wall 3 and the roof 1 of the frame structure of this building. The roof panel 4 is attached to a purlin material (including a purlin and eaves girder, not shown) which is a structural material of the roof portion 1.

The roof portion 1 in the illustrated example is formed as a ridge roof (also referred to as a ridge structure). The roof portion 1 has a rectangular standard roof panel 4a and an eaves roof panel 4b as roof panels. A triangular standard corner panel 4c, an eave corner panel 4d, etc., which are arranged on both sides of the corner building 5, are used. The present invention is applied to the standard corner panel 4c and the eave corner panel 4d.

FIG. 1 is a front view showing an embodiment in which the present invention is applied to an eaves corner panel, and FIG. 2 is a sectional view taken along line AA of FIG. The eaves corner panel 4d is made up of a frame 7, face members 8a and 8b attached to both sides of the frame 7, and a heat insulating material 9 which is foam-filled inside defined by the frame 7 and the surface members 8a and 8b. It is mainly composed. The framework 7
At least one frame member is a diagonal member 6a,
In the frame 7, there is a hanging wood 10 as an intermediate frame material.

These frame members 6a, 6b, 6c, 10
For example, it is made of lumbar material for a roof. Framework 7 is
A vertical member 6b, a horizontal member 6c joined to the one end of the vertical member 6b at a right angle (or a substantially right angle), and the vertical member 6b and the horizontal member 6
It is assembled in a triangular shape by the diagonal member 6a which is bridged over and joined to c. For joining these frame members 6a, 6b, 6c, for example, nails, which are fasteners, are used. In this case, in order to arrange a plurality (three in the illustrated example) of the hanging wood 10 in the frame 7 in parallel with the vertical member 6b, the horizontal member 6c is divided into a plurality of parts (four in the illustrated example). Crossing material 6
The vertical lumber 10 is sandwiched between c and fixed by nailing.

The vertical lumber 10, which is an intermediate frame member, may be referred to as an intermediate vertical member because it is parallel to the vertical member 6b. One end of the hanging wood 10 is in contact with the inner surface of the diagonal member 6a, and the other end of the hanging wood 10 penetrates the cross member 6c and protrudes out of the framework 7 to form an eave tip 10n. The other end of the diagonal member 6a also extends so as to be aligned with the eaves portion 10n of the hanging wood 10. In addition, an auxiliary vertical lumber 11 is attached to the inner side surface of a portion of the diagonal member 6a protruding from the horizontal member 6c by nailing in parallel with the vertical lumber 10.

The hanging wood 10 has an end face 10a that is substantially perpendicular (or perpendicular) to its longitudinal direction.
Oa is obliquely abutted against the inner surface of the diagonal member 6a to be joined, and the gap 12 formed between the diagonal member 6a and the end surface 10a of the hanging wood 10 is filled with the heat insulating material 9. That is, since one end of the hanging wood 10 is cut at a substantially right angle to the longitudinal direction, the hanging wood 1 is attached to the inner surface of the diagonal member 6a.
0 end face 10a, the end face 1 of the hanging wood 10
0a only partially contacts the inner surface of the diagonal member 6a,
The end surface 10a of the hanging wood 10 and the slant 6
A wedge-shaped gap 12 is generated between the inner surface of the line a. The heat insulating material 9 filled by injection foaming into the framework 7 wraps around and is buried in the gap 12, whereby the joining strength between the hanging wood 10 and the oblique material 6a is reinforced.

In order to further improve the bonding strength between the hanging wood 10 and the slant 6a, the end face of the hanging wood 10 is cut with the slant 6a.
It is preferable that the vertical lumber 10 and the oblique member 6a be joined to each other by a nail 13 which is a fixing tool which is driven into the oblique member 6a at a substantially right angle (and a right angle). In this case, since the nail 13 is driven at a substantially right angle to the diagonal member 6a, the nail 13 can be driven relatively easily, the diagonal member 6a and the hanging wood 10 can be easily joined, and the assembling property can be improved. The processing cost can be reduced due to the improvement of the assembly time and the labor for assembling. Further, if a nailing machine is used to drive the nail 13, the assembling workability can be further improved.

After the hanging wood 10 is attached to the frame 7 in this manner, the face materials 8a and 8b are attached to both sides of the frame 7. In this case, a nail may be used, but it is preferable to use a staple in terms of sticking strength and work efficiency. Face material 8
As a and 8b, it is preferable to use a surface material for a load-bearing wall, for example, a structural plywood, a particle board, an OSB (oriented strand board), or the like. In addition,
As the face materials 8a and 8b provided on both sides of the framework 7, both sides may be plywood, but one side may be paper, sheet or the like. That is, besides the plate material,
Paper, sheets, etc. are also included.

Then, the frame 7 and the face materials 8a, 8b
Are held down from the outside, the frame 7 and the face materials 8a, 8
The interior defined by b may be filled with a heat insulating material 9 made of, for example, a foamed polyurethane foam by injection foaming, whereby a roof panel made of a heat insulating panel, in this embodiment, an eaves corner panel 4d is completed. Also, in this case,
By injecting and filling the heat insulating material 9 into the interior defined by the frame 7 and the face materials 8a and 8b, as described above, the heat insulating material 9 wraps around the gap 12 between the hanging wood 10 and the oblique member 6a, and is buried. The joining strength between the wood 10 and the oblique member 6a is enhanced.

The eaves corner panel 4d thus constructed
, A frame 7, face materials 8 a and 8 b attached to both sides of the frame 7, and the frame 7 and face materials 8 a and 8 b
And at least one frame material of the framework 7 is an oblique material 6a, and there is a lumber 10 which is an intermediate frame material in the framework 7;
The hanging wood 10 has an end face 10a that is substantially perpendicular to the longitudinal direction thereof, and the end face 10a is abutted against the diagonal member 6a and joined, and the gap 12 between the diagonal member 6a and the hanging wood 10 is connected to the heat insulating material. Filled with 9. For this reason, since the end face 10a of the hanging wood 10 is joined to the diagonal member 9a while remaining substantially at a right angle, there is no need to perform diagonal cutting, and only one cutting step of cutting at a substantially right angle is required. Therefore, the cutting can be simplified and the processing cost can be reduced as compared with the conventional one requiring two cutting steps.

A gap 12 is formed between the diagonal member 6a and the hanging wood 10, and the gap 12 is filled with the heat-insulating material 9 to be foam-filled. , And the joint strength between the hanging wood 10 and the oblique member 6a can be secured.
In addition, since the hanging wood 10 and the diagonal member 6a are joined by a nail 13 driven into the diagonal member 6a at substantially right angles, the nail 1
The driving operation can be performed easily and accurately as compared with the conventional one in which the member 3 is driven obliquely to the oblique member 6a. As a result, the processing cost can be reduced and the assemblability can be improved by reducing the labor for assembling. The nail 13 is driven into the hanging wood 10 at an angle, and a gap 12 is formed between the hanging material 6a and the hanging wood 10;
However, as described above, since the heat insulating material 9 is buried in the gap 12 between the diagonal member 6a and the rafter 10 to reinforce it, the bonding strength between the diagonal member 6a and the rafter 10 is sufficient. Has been confirmed by a load test.

FIG. 5 is a front view showing an embodiment in which the present invention is applied to a standard corner panel. This standard corner panel 4
c is mainly composed of a framework 7, face members 8a and 8b adhered to both sides of the frame 7, and a heat insulating material 9 foamed and filled in the interior defined by the framework 7 and the face members 8a and 8b.

The oblique material 6a is assembled into a triangle by nailing. In this case, the rafters 10 are provided in the frame 7 in parallel with the vertical members 6b, but unlike the eaves corner panel 4d, the rafters 10
Are disposed between the oblique member 6a and the horizontal member 6c, and do not protrude outside from the horizontal member 6c.

That is, one end of the hanging wood 10 is connected to the diagonal member 6a.
And the other end of the hanging wood 10 abuts on the inner surface of the cross member 6c at a substantially right angle and is joined by nailing. The hanging wood 10 has an end face 10a that is substantially perpendicular to the longitudinal direction, and the end face 10a is joined obliquely to the diagonal member 6a. The gap 12 between the slant 6a and the hanging wood 10
Is filled with the heat insulating material 9 to be injected and foamed, and the joining strength between the hanging wood 10 and the oblique material 6a is reinforced. In order to further improve the bonding strength between the hanging wood 10 and the slant 6a, the hanging wood 10 and the slant 6a are connected to the slant 6a with the end surface 10a of the hanging wood 10 abutting against the slant 6a. Are joined by a nail 13 which is a fixing tool which is driven substantially at right angles to the fixing device. Therefore, the same effect as the eaves corner panel 4d of the embodiment can be obtained also by the standard corner panel 4c of the embodiment.

The embodiments of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to the above embodiments, and various design changes and the like can be made without departing from the gist of the present invention. Is possible. For example, as shown in FIG. 4, the present invention can be applied to an eave corner panel 4d and an eaves valley panel 4e provided on an L-shaped roof portion 1 in which a gable roof 1x and a ridge roof 1y are combined. Similarly, it can be applied to the main house roof. Further, the present invention is also applicable to an arrow cut panel which is a wall panel provided on the gable wall 3x. In this case, the present invention is applied to the joining structure of the oblique member of the framework and the intermediate frame member.
