BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating panel arranged inside an outer wall of a detached house or the like.
[0002]
[Prior art]
In general, the wall of a conventional wooden building is difficult to ensure the rigidity of the joint, so it is reinforced by bracing to prepare for horizontal force such as seismic force. In order to construct, pillars are built one by one between the pillars, and in many cases, the walls are filled with heat insulating material.
[0003]
However, reinforcement by bracing is used to fix the end of the bracing, and part of the columns and beams, and when the bracing intersects, the bracing body is often partially cut off, so the strength due to the cross-sectional defect Decline is inevitable, and bracing cannot be installed on all walls, so it is not always possible to sufficiently reinforce, in many cases it is necessary to reinforce bracing joints with reinforcing brackets, etc. It had many problems to be solved.
[0004]
Therefore, for example, Japanese Patent Laid-Open No. 5-302387 (Patent Document 1) enables on-site construction to be simplified, omitted, and the construction period can be shortened while maintaining durability, functionality, heat insulation, airtightness, and the like. As a wall panel that enables improvement, a plurality of inter-columns are connected by upper and lower connecting members, a reinforcing plate is attached to one side portion of the inter-posts and the connecting member, a heat insulating material is attached to the outdoor side of the reinforcing plate, and It has been proposed to form a rectangular plate by attaching a ventilator edge to the outdoor side of the heat insulating material.
[0005]
In Japanese Patent Laid-Open No. 9-23596 (Patent Document 2), the space portion is closed by fitting into a space portion surrounded by aggregates such as pillars, duck, beams, bundles, rafters, etc. of a wooden house. When a frame is provided, a frame is provided, a flat plate is provided on one side of the frame, and the flat plate is fitted in the space portion in a state of being located on the inner side of the frame, the flat frame A heat insulating material to which an inner wall material is attached with a predetermined thickness is provided on the entire surface opposite to the surface on which the body is provided, and this heat insulating material has a thickness that is the same as the thickness of the aggregate between the frame and the flat plate. Panels for building wooden houses that have been set up are proposed.
[0006]
[Problems to be solved by the invention]
The panels described in each of the above-mentioned patent documents all have a heat insulating effect, and when a heat insulating material is attached to a flat face material fixed to a rectangular frame member, most of the heat insulating material used is foamed. Since it is made of resin and adhesive is applied to the entire surface of the face material and the heat insulating material is adhesively bonded, it is extremely difficult to separate and dispose of the heat insulating material from the face material when disassembling. However, it has been pointed out that the component members cannot be separated and recycled.
[0007]
For this reason, there is a method of fixing the heat insulating material to the face material with a fastener such as a nail or a screw. However, since the heat insulating material is generally made of foamed resin, a nail or screw is used for fixing. Since it is difficult to fix the heads of all of them at a constant level and easily transfer heat, the surroundings of the nails or screws are likely to condense, and the water droplets adhere to the face materials, foundations, pillars, etc. May cause rotting.
[0008]
In view of the present situation, the present invention can fix a heat insulating material to a face material using a fastener such as a screw, without causing condensation, and when disposing of the heat insulating material and the face material, It is intended to provide an insulating panel that can be easily separated.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of the heat insulation panel according to the present invention will be described. The heat insulation panel 1 includes a pair of left and right vertical frame members 2 and 3 disposed at a predetermined interval, and the pair of vertical frame members 2. , 3, a rectangular frame member 6 composed of a pair of upper and lower horizontal frame members 4, 5 that integrally connect the upper and lower portions of the frame member 3, and a frame member 6 on one side, for example, the front side thereof. A flat plate member 7 having the same thickness as the frame member and having a required thickness, and a heat insulating material 8 mounted on the surface member 7 and the heat insulating member 8 are attached to the plate member 7 or the frame member. 6 and a fastener 10 for fixing to 6.
[0016]
In general, the frame material forming the rectangular frame member 6 is basically four pieces, upper and lower and left and right. However, an auxiliary vertical member is provided between the central portions of the upper and lower horizontal frame members 4 and 5. There are no particular restrictions on the size or thickness of the frame material used.
[0017]
If the face material 7 has the same shape as the frame member 6 and a flat plate shape, the thickness thereof is not particularly limited, and on the surface thereof, rock wool, glass wool, foam polyethylene, polyurethane foam, pearlite, installation board, etc. Particularly preferably, a heat insulating material 8 made of extruded polystyrene foam is fixed to the frame member 6 using a fastener 10.
[0018]
Specifically, the fastener 10 is a screw having a screw formed on a shaft having a required length or a shaft having a required length, and the fixing of the heat insulating material 8 by the fastener 10 has a specific shape. A washer 11 and a cap 16 that is press-fitted into the washer 11 are used. Note that the length of the fastener differs depending on the thickness of the heat insulating material 8 to be used, and whether the tip end of the fastener is fixed to the face material 7 or the frame member 6.
[0019]
As is apparent from FIGS. 2 to 3, the washer 11 is composed of a synthetic resin-made truncated inverted conical hollow body, the top portion 12 of which is closed by a homogeneous thin film 13 and the inner periphery thereof. A ring-shaped step portion 14 that engages with a screw head 10a as an example of the fastener 10 is formed in the portion, and an engagement portion 15 that engages and holds the outer peripheral portion of the cap 16 is formed. Yes.
[0020]
On the other hand, the cap 16 has a dome shape as a whole, and has a diameter that allows the outer periphery of the cap 16 to be engaged with the engaging portion 15 of the washer 11. The cap 16 is molded of the same synthetic resin as the washer 11. As long as the engaging portion 15 can engage and hold the outer peripheral portion of the cap 16, the shape of the engaging portion 15 is not particularly limited.
[0021]
In order to fix the heat insulating material 8 to the frame member 6 using the washer 11, the cap 16 and the fastener 10, first, the tip 10b of the fastener 10 is pierced into the thin film 13 that closes the top 12 of the washer 11. After that, for example, in the state where the penetrated head portion 10 a is immersed in the washer 11, the tip portion of the screw 10 is press-fitted into the heat insulating material 8, and the face material 7 fixed to the frame member 6 or the frame member 6 is configured. When the distal end portion 10 b comes into contact with the vertical frame members 2, 3 or the horizontal frame members 4, 5, the fastener 10 is tightened and screwed to fix the heat insulating material 8 to the face material 7 or the frame member 6.
[0022]
As described above, the washer 11 is made of a truncated conical hollow body, so that the washer 11 can be easily bited into the heat insulating material 8 when the fastener 10 is screwed in. As shown in FIG. 3, the thin film 13 punctured by 10 b comes into close contact with the shaft portion of the fastener 10 due to the elasticity of the thin film 13, so that water droplets or the like pass through the shaft portion and the heat insulating material 8. It is possible to prevent entry into the inside as much as possible.
[0023]
In this state, the washer 11 is also immersed in the heat insulating material 8, the opening on the fastener insertion side is flush with the surface of the heat insulating material 8, and the head 10 a of the fastener 10 is connected to the stepped portion 14 in the washer 11. The cap 16 is pushed into the washer 11 while being pressed lightly, so that the outer peripheral portion of the cap 16 is formed in the washer 11. At the same time as engaging 15, the back surface of the fastener 10 is kept in close contact with the top surface of the head 10 a.
[0024]
Therefore, since the fastener 10 is held in the washer 11 in a sealed state by the cap 16, it is almost completely shut off from the outside air, and heat is hardly transmitted to the shaft portion of the fastener 10, so that almost no condensation occurs. It does not occur, and there is no possibility that water droplets generated by condensation adhere to the face material 7 or the frame member 6.
[0025]
In FIG. 1, reference numeral 17 denotes a trunk edge disposed in the center of the heat insulating material 8, and the outer wall is attached using the trunk edge 17.
[0026]
The washer 21 shown in FIGS. 4 to 5 is an example of another washer used in the heat insulating panel 1 of the present invention. Like the washer 11 in FIG. 3, a truncated inverted conical hollow made of synthetic resin is used. The opening of the top 22 of the body is closed with a thin film 23 of the same quality, and a cap 26 is integrally attached to a part of the outer periphery of the bottom via a thin belt 27, A step portion 24 that engages with the head portion 10a of the fastener 10 is integrally formed in a ring shape on the peripheral portion, and an engagement portion 25 that engages with the outer peripheral portion of the cap 26 is formed on the upper portion thereof. It is formed in a ring shape, and is different from the washer 11 shown in FIGS. 2 to 3 in that the cap 26 is provided integrally with a washer 21 and a belt 27 having a required length. It is.
[0027]
4 and 5, reference numeral 28 denotes a guide groove formed to prevent the cap 26 from being lifted by the belt 27 when the cap 26 is engaged and held by the engaging portion 25.
[0028]
Further, in order to separate the heat insulating material 8 from the frame member 6, when the cap 16 is independent of the washer 11, as shown in FIG. 3, the outer peripheral portion of the washer 11 is pressed toward the heat insulating material 8 with the fingertip. For example, the cap 16 is pushed upward by the head portion 10a of the fastener 10 and can be easily removed from the washer 11. Also, as shown in FIGS. 4 to 5, the cap 26 is connected to the washer 21 and the belt 27. The cap 26 can be removed by lifting the belt 27 upward.
[0029]
【The invention's effect】
The heat insulating panel of the present invention uses a fastener when fixing the heat insulating material to the frame member or the face material constituting the heat insulating panel, and the head of the fastener is placed in a washer made of synthetic resin. Since the head is sealed with a cap, the fastener is completely blocked from the outside air, the outside air temperature is not directly transmitted to the fastener, condensation is unlikely to occur, and water droplets adhere to the face material and frame member, etc. Corrosion can be prevented.
[0030]
In particular, since the heat insulating panel of the present invention uses a fastener when fixing the heat insulating material to the face material or the frame member, it forms a nonflammable heat insulating material and the face material or the frame material when dismantling the house. Since it can be easily and easily separated from the wood to be used, each component can be recycled as necessary, and can be separated and disposed of, and has a great effect on preventing condensation. Since the durability of the housing is improved and no adhesive is used, there are great effects such as no generation of harmful substances in the production and disposal of the heat insulation panel.
[0031]
Further, when using a synthetic resin washer so that the outside air temperature is not transmitted to the fastener, by making the washer into a truncated conical hollow body, the washer can easily bite into the heat insulating material, By closing the opening at the top of the hollow body with a thin film in advance and breaking through the thin film at the tip of the fastener, the broken thin film adheres to the shaft of the fastener, further improving the dew condensation prevention effect. In addition, the structure is simple and easy to handle.
