Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-functional structural panel.

[0002]

[Prior art]

 In wooden structures and the like, heat insulating materials made of expanded synthetic resin are widely used in order to enhance the airtightness and heat insulating properties inside the buildings.

On the other hand, from the viewpoint of simplifying the construction work of a wooden building, a panel in which a plate material or the like is joined to both surfaces of a heat insulating material has been developed and put into practical use. If such a panel is formed with the plate materials on both sides having a certain strength, it is possible to construct walls, floors, etc. without using the structural members of wooden structures such as columns and joists that were required in the past. You can do it.

Further, according to the construction method using such a panel, not only these structural members can be omitted, but also the assembling is easy and almost no carpentry skill is required, the construction period can be shortened, and the panel can be consistently manufactured. There is an advantage that the cost can be reduced by the production.

FIG. 7 shows such a conventional structural multifunctional panel. In this panel 1, a heat insulating material 2 made of expanded polystyrene is used as a core material, and plywoods 3 and 3 having a predetermined strength are attached to both surfaces thereof.

When the panels 1 and 1 are to be matched with each other, as shown in FIG. 8, the end portions are brought into contact with each other and the sub plates 4 and 4 are placed in the gap of the heat insulating material 2 so that both of them are joined together. The spaces are joined.

[0007]

[Problems to be solved by the device]

 By the way, when such a panel 1 is incorporated into a building, there are the following problems.

That is, in winter and the like, the temperature inside the room is higher and the humidity is higher than that outside. Therefore, the water vapor on the indoor side tends to radiate outward through the plywood 3'on the inner side. Therefore, water vapor may pass through the plywood 3 ′ and enter the heat insulating material 2.

However, when the water vapor enters the heat insulating material 2 in this way, the water vapor is condensed on the contact surface between the heat insulating material 2 and the plywood 3 on the back side when the temperature becomes cold at night. There is a problem that ends up.

In particular, such a phenomenon tends to occur when the moisture permeability resistance of the plywood 3 is larger than that of the heat insulating material 2. Therefore, in order to prevent the dew condensation in the conventional panel 1, it is necessary to sufficiently consider the magnitude of the moisture permeation resistance when selecting the material of the panel constituent member.

In view of the above situation, the present invention can reliably prevent dew condensation in the panel regardless of the selection of the material of the panel constituent member such as the structural plate material, and maintains an appropriate heat insulating effect for a long time. The purpose of the invention is to provide a structural multi-functional panel suitable as a constituent material for walls, floors, roofs and the like.

[0012]

[Means for Solving Problems]

 The present invention for achieving the above object is provided with a plate-shaped heat insulating material made of a foamed synthetic resin and structural plate materials attached to both sides of the heat insulating material, and the end portions of the heat insulating material are abutted against each other on a base and arranged. By doing so, it is possible to construct a wall of a self-supporting building, and by arranging the ends of the building on the wall of the building, the ceiling or floor that can bear the load by itself can be constructed. The functional panel is characterized in that a ventilation layer is formed between the heat insulating material and one of the structural plate members on the side of the structural plate member that is arranged outside the building.

[0013]

[Advantageous Effects] According to the above configuration, since the ventilation layer is formed on the surface arranged on the outside of the building, even if steam enters the plate material of the panel from the inside of the building, the water vapor will pass through the ventilation layer. It leads you to the upper side of the building. Therefore, if a predetermined opening is provided above, water vapor can be released from the opening to the outside air.

Therefore, there is no risk of dew condensation within the panel even when the magnitude of the moisture vapor transmission resistance of the panel constituent members is not taken into consideration, which makes it possible to provide a highly insulated building with excellent airtightness. Can contribute.

Further, since this panel itself is a constituent material for walls, floors, roofs, etc., when it is used as a wall panel, for example, structural members such as columns and studs become unnecessary, and carpentry skills are improved. It can be made almost unnecessary and the construction period can be shortened.

Further, it is possible to freely design by combining the panels.

【Example】

 The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 shows a multi-function panel 10 according to an embodiment of the present invention.

The multi-function panel 10 is made up of a plate-shaped heat insulating material 11 and rectangular structural plate materials 12 and 13 attached to both surfaces of the heat insulating material 11. The plate-shaped heat insulating material 11 is made of synthetic foam resin such as expanded polystyrene, expanded polyurethane, and expanded polypropylene.

Further, as another heat insulating material having a predetermined heat insulating property, for example, a quasi non-combustible material made of a foam containing a vinyl chloride resin containing an inorganic filler or a chlorinated vinyl chloride resin as a main component. There is a heat insulating material composed of. In this case, not only the heat insulation performance, but also the fire resistance performance and light weight are excellent. Further, the other heat insulating material may be a heat insulating material formed of, for example, acrylic resin, vinyl chloride, phenol resin, or the like. In short, the material is not limited as long as it is a synthetic resin having a heat insulating property. Moreover, the expansion ratio is arbitrary.

As shown in FIG. 1, the heat insulating material 11 has predetermined voids S, S formed in the upper and lower portions in a state of standing upright in the longitudinal direction. That is, the length in the longitudinal direction is set shorter than that of the structural plate members 12, 13. On the other hand, substantially rectangular projections 21 are formed at predetermined intervals on the surface of the heat insulating material 11 that is in contact with one of the structural plate materials 13. As a result, the panel 10 is formed with the ventilation layer A continuous in the vertical and horizontal directions.

Further, in a state in which the panel 10 is erected, recesses 14 and 14 for inserting a sub plate later are formed on a lateral end surface of the heat insulating material 11, whereby the end surface is formed in a convex shape. ing.

The structural plate members 12 and 13 are made of the same material, and are, for example, structural plywood such as a chip board and a wafer board. Further, other materials may be used, and the material is not limited at all.

A plurality of panels 10 formed in this way are prepared and can be used as wall panels, for example, as shown in FIG. That is, the floor material 16 is arranged on the foundation 15. This floor material 16 may also be constructed from the panel 10.

Further, the lower frame 17 is struck on the upper portion of the floor material 16 with a nail or the like. The lower frame 17 is made of a long object that fits into the gap S provided above and below the panel 10.

After hitting the lower frame 17 as described above, the lower part of the panel 10 is sandwiched in the lower frame 17, and the panel 10 is aligned and erected. At that time, the structural plate material 13 provided with the ventilation layer A is arranged on the outdoor side, and the other structural plywood 12 is arranged on the indoor side.

When one panel 10 is placed in this manner, a structural adhesive is applied to the entire joint surface between this panel 10 and the adjacent panel 10, and as shown in FIG. The sub plates 18, 18 are inserted into the recesses 14, 14. Next, as shown in FIG. 4, nails 20 are driven into the panel 10 at a predetermined interval to join the panels.

A structural adhesive may be applied between the sub plates 18 and 18 and the structural plate members 12 and 13. In this way, the panel 10 and the adjacent panel 10 are arranged side by side, and a wall that can bear the load by itself is constructed. Further, air can freely flow in the ventilation layer A arranged on the outer side of the building.

As shown in FIG. 3, an upper frame 19 of a long object is provided above the panel 10 like the lower frame 17. As a result, a wall portion, which is integrated with the lower frame 17 and the upper frame 19, is constructed around the building.

As described above, when the panel 10 is used upright as a wall panel, the vertical compressive force can be borne by the structural plate members 12 and 13 on both sides. Therefore, by using the panel 10 of this embodiment, it is possible to construct a wall portion having a predetermined strength without using structural members such as columns, studs, and braces.

Therefore, the building can be constructed with saving resources, and the workability and productivity of constructing a wooden building are improved. Further, when a window or the like is installed, a cut may be formed in a predetermined place of the panel 10 in advance, and a window frame may be fitted in this portion. As a result, it is possible to easily perform processing such as opening on the spot.

Next, with reference to FIG. 5, the connection between the wall surface and the roof will be described. On the upper part of the panel 10 installed as a wall panel, a rafter receiver 26 having an appropriate inclination is arranged. Due to the inclination of the rafter receiver 26, the upper roof material 27 is supported at a predetermined inclination. A panel similar to the panel 10 may be used as the roof material.

The roof material 27 and the panel 10 are integrally fastened by inserting the nail 28 from the roof material 27 into the upper frame 19. On the roof material 27, a ventilation layer B communicating with the ventilation layer A of the panel 10 is formed. This operation can be easily performed on site when the panel 10 is used as a roofing material, but may be formed in advance.

In this way, the ventilation layer A is communicated with the ventilation layer B communicating with the outside air in the upper portion of the panel 10. When the panel 10 is used as a wall panel as in the present embodiment, the air flow in the ventilation layer A is always upward. Therefore, by forming the connecting portion in this way, the air in the ventilation layer A can be released to the outside air through the ventilation layer B.

Therefore, according to the present embodiment, the warm water vapor on the indoor side reaches the boundary surface between the heat insulating material 11 and the structural board material 13 through the structural board material 12 and the heat insulating material 11 of the panel 10 in the winter season. Even so, the water vapor is guided to the upper side of the panel 10 by the air flowing through the ventilation layer A, further flows into the ventilation layer B, and is diverged outward from the ventilation layer B.

Therefore, dew condensation does not occur in the panel 10. Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiment, the substantially rectangular protrusion 21 is formed on one surface of the heat insulating material 11 in order to form the ventilation layer A. However, the shape of this protrusion 21 is different from that of the embodiment. The shape is not limited, and may be, for example, a round shape or a rhombus shape. Further, in the embodiment, the protrusions 21 are arranged vertically and horizontally at predetermined intervals, but the protrusions 21 may be arranged in a staggered manner. Further, although the ventilation layer A of the above-mentioned embodiment is communicated in the vertical and horizontal directions, the projection may be formed in a strip shape extending in the vertical direction so that the ventilation layer may be communicated only in the vertical direction. As described above, the shape of the protrusion is not limited to the embodiment.

Further, although the present invention is applied to the wall panel in the above-mentioned embodiments, these panels can be used as a floor panel or a roof panel. When the panel 10 is used horizontally as a floor panel, the structural plate members 12 and 13 on both sides can bear the compressive force and the tensile force due to bending, and the shear force can be applied to the heat insulating member 11 and the structural plywood plates 12 and 13. Can be covered by

Further, in the above embodiment, an example of constructing a building by completely omitting structural members such as columns is shown. However, if necessary, a corner portion of the building or a portion to which a vertical load is applied is provided with a stud. You may insert material.

Further, in the above embodiment, the heat insulating material 11 and the other structural plate material 12 are directly adhered to each other. However, as shown in FIG. 6 between them, the moisture proof that does not allow water vapor to pass therethrough. The layer 27 may be interposed. The moisture-proof layer 27 is formed of, for example, a waterproof coating film layer having adhesiveness such as urethane resin. When such a resin is applied, its thickness is 0.5 to 1 mm or more. Other moisture-proof layers include plastic films such as polyethylene, biphenyl chloride, and vinylidene chloride. You may adhere | attach these films and form a moisture-proof layer. In that case, the thickness of the film is about 100 to 300 μm. Further, as another moisture-proof layer, an asphalt sheet having a thickness of about 1 to 2 mm may be bonded and formed. Alternatively, an aluminum foil, an aluminum vapor deposition film, or the like having a thickness of 30 to 100 μm may be attached. However, it is rational to apply urethane resin, which has adhesiveness, considering the process at the site.

By interposing such a moisture-proof layer 27, it is possible to prevent further permeation of water vapor on the indoor side after passing through the structural plywood 12, thereby further preventing the occurrence of dew condensation. can do.

[Effect of device]

 As described above, according to the multi-function panel of the present invention, even if water vapor enters the plate material of the panel from the inside of the room, the water vapor will be transmitted to the outside by the air flowing through the outside ventilation layer. Can be discharged to.

Therefore, even if such a panel is used for a long period of time, there is no risk of dew condensation within the panel, which can contribute to the provision of a highly insulated building having excellent airtightness.

Further, since this panel itself becomes a constituent material for walls, floors, roofs, etc., when it is used as a wall panel, for example, structural members such as columns and studs become unnecessary, and carpentry skills are improved. It can be made almost unnecessary and the construction period can be shortened.
