Abstract

PROBLEM TO BE SOLVED: To accommodate to various wall surface (openings) structures and design changes and raise free of degree in construction by making it available to cut panels and change sizes. SOLUTION: The wall surface heat insulation panel has a heat insulation layer 16 formed by injecting a foam resin material (a hard foam urethane) between boards 12, 13. A stopper 12a availing the panel to be fixed is formed by extending the outdoor side board 12 beyond the heat insulation layer 16 and the indoor side board 13 by a specific width circumference and making it abut on wall assembly members. A separation means 21 capable of making the board 12 and the heat insulation layer 16 separatable is arranged beforehand on the inner surface of the board 12 at suitable intervals. The preferable direction of arranging the separation means 21 is in the vertical direction. The separation means 21 is composed by, for example, taping the back of the board 12 with a smooth adhesive tape or by directly applying a separation agent on the board 12. When the panel is cut and the stopper 12a is formed on the cut section, the heat insulation layer 16 can be easily removed because the separation means 21 is arranged.

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 in which a plate material and a heat insulating material are integrated, and more particularly, to a structure of a panel which enhances flexibility in cutting and using as required.

[0002]

2. Description of the Related Art Recently, various types of heat insulating panel materials in which a building structural material and a heat insulating material are integrated in advance have been proposed. For example, Japanese Examined Patent Publication No. 5-38101 constructs a building floor surface, a wall surface, and a ceiling surface by using panel materials 1 and 2 integrally provided with a heat insulating material as shown in FIG. Inject foamable resin into wood frames 1a-1h, 2a-2h,
The heat insulating material 3 is formed integrally. These various panels provided with a heat insulating material in advance have an advantage that the work efficiency can be increased and the construction cost can be reduced as compared with a conventional heat insulating method in which a heat insulating material such as glass wool is loaded on site.

[0003]

However, in the conventional heat insulating panel, there are many cases where the cutting use of the panel becomes complicated or difficult. In addition, since it is difficult to freely cut and use, there are cases where it is difficult to respond to various requests and requests that occur for each individual building, such as design changes, and there is a difficulty in the flexibility of construction.

For example, when it is desired to change the height position of the window frame opening, it is difficult to freely change the window position with a conventional heat insulating panel. Including the Japanese Patent Publication No. 5-38101,
This is because the conventional heat-insulating panel is provided with various frame materials. When the panel is cut, the frame (reinforcement aggregate) is separated and does not function as a wall panel.

[0005] In addition, various openings such as door openings, windows in living rooms and bedrooms, ventilation windows in baths and toilets are required on the wall surfaces, and the size and arrangement of these openings are different for each individual house. In many cases, it is different, and it is difficult to construct a wall only with a combination of panels of an existing size.

On the other hand, it is conceivable to prepare a large number of panel sizes so as to be able to respond finely to various wall (opening) structures and design changes. However, if the number of types of panels is increased, the production cost is increased and Problems such as increasing the number of products in stock and complicating on-site material management and construction may occur, and the benefits of using panel materials (such as lower cost and more efficient construction) may be reduced. is there.

An object of the present invention is to make it possible to freely cut a panel and to freely cope with various wall structures and design changes.

[0008]

Means for Solving the Problems In order to achieve the above-mentioned objects and to solve the problems, a wall heat insulation panel according to the present invention is provided by injecting a foamable resin material between plate members arranged at predetermined intervals,
Assuming that a heat insulating panel having a heat insulating layer formed between the plate materials is a technical premise, an outdoor side plate material of the plate materials is extended around a predetermined width from the heat insulating layer and an indoor side plate material, and is brought into contact with a wall assembly material. While forming a locking portion capable of fixing the panel, peeling means capable of separating the heat insulating layer from the outdoor side plate material were previously disposed on the inner surface of the outdoor side plate material at appropriate intervals.

In some cases, the direction in which the peeling means is provided is the vertical direction.

[0010]

The heat insulation panel of the present invention is a panel material for constructing a wall surface, and is formed by injecting a foamable resin material between plate materials arranged at predetermined intervals to integrally form a heat insulation layer. Panels will be installed from the outdoor side into wall sets (including columns, studs, eaves girder, body gap, base, windows and door opening frames). Therefore, among the plate members constituting the panel, the outdoor side plate member (hereinafter, referred to as an outer plate) is extended around a predetermined width from the heat insulating layer and the indoor side plate member (hereinafter, referred to as the inner plate). The stop is brought into contact with the wall assembly so that the panel can be fixed. Note that a core material, an interior receiving material, and the like may be appropriately provided in the panel (between the outer plate and the inner plate).

On the other hand, on the inner surface of the outer plate (outdoor side plate material), a peeling means capable of peeling off the heat insulating layer from the outer plate is provided in advance. This peeling means enhances the workability when the panel is cut and the size is changed.

That is, since the present panel does not have a structure in which a wood frame is provided around the panel unlike a conventional panel material,
It is possible to cut the panel freely on site and change the height and width dimensions. However, when the panel is cut, the locking portion for fixing the panel is lost in the cut portion, so that the inner plate (the indoor side plate material)
It is necessary to remove the heat insulating layer and the predetermined width (by the width of the locking portion) and newly form the locking portion. However, the foamable resin (for example, hard urethane foam) that forms the heat insulating layer has a strong self-adhesive force, and it is not easy to remove the heat insulating layer that is in close contact with the outer plate. Therefore, in this panel, a peeling means is disposed in advance between the outer plate and the heat insulating layer so that the heat insulating layer (along with the inner plate) can be easily removed.

Specifically, for example, an adhesive tape having a smooth back surface (a so-called gum tape or resin tape) can be used as the peeling means. Further, it is also possible to constitute a peeling means by directly applying a peeling agent (for example, a silicone resin) to the inner surface of the outer plate. However, these peeling means are not provided on the entire inner surface of the outer plate (the entire contact surface with the heat insulating layer), but are preferably provided at appropriate intervals (for example, in a stripe shape). While facilitating the formation of the locking portion (peeling of the heat insulating material), it also prevents the heat insulating layer from peeling off from the outer plate during panel transport or construction, and further ensures the hermetic insulation of the panel after construction. That's why.

The direction in which the peeling means is disposed is preferably in the vertical direction (vertical direction). As a result of conducting various studies on the arrangement pattern of the peeling means, it was found that a favorable result that the heat insulating layer can be easily peeled and the locking portion can be formed regardless of the cutting position (especially the height position) regardless of the cutting position of the panel. Obtained
This is because there is no following inconvenience. That is, when the peeling means was provided in a scattered manner (in a polka dot shape), the effect of disposing the peeling means was not sufficient, and it was somewhat difficult to peel off the heat insulating layer.
In addition, when the peeling means is arranged horizontally at appropriate intervals, when the upper end of the heat insulating layer comes to the position where the peeling means is disposed, the upper end of the heat insulating layer is easily peeled off during construction and becomes unstable. was there. However, the present invention does not exclude a pattern other than the vertical direction in the arrangement pattern of the peeling means. This is because workability is improved even when provided in a scattered manner as described above or when provided in a horizontal direction, as compared with a panel configuration in which no peeling means is provided.

[0015]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 are a perspective view showing an example of a wall heat insulation panel according to the present invention and a cross-sectional view showing a construction state. As shown in these figures, the panel material 11 includes a structural plywood 12 (eg, 9 mm thick) as an outdoor side plate material and a Rawan veneer plywood 13 (eg, 4 m thick) as an indoor side plate material.
m thickness), a core material 14 and a body edge (interior receiving material) 15 are provided between these plywoods 12 and 13, and a heat insulating layer 16 is formed. In forming the heat insulating layer 16, the plywood 12, 1
After the periphery of 3 is closed with a jig, for example, urethane foam (hard urethane foam resin) is injected into the inside. In FIG. 1, panels (the inner plate 13, the heat insulating layer 16, etc.) are partially cut away to show the internal structure.

The panel 11 is installed on a wall (post 30, stud 3).
1, base 32, body gap 33, eaves girder 34, etc.) from outside. For this reason, the outdoor side plate member (outer plate) 12 is extended from the indoor side plate member (inner plate) 13 and the heat insulating layer 16 to the periphery, and a locking portion 12 for fixing the panel 11 to the wall assembly member.
a is formed. An airtight material 17 is provided on the inner peripheral edge of the locking portion 12a so as to surround the heat insulating layer 16, and an airtight material 18 is provided on the entire inner peripheral end of the heat insulating layer 16 on the indoor side. It is. These airtight materials 17, 18
Is made of an elastic material such as urethane resin or sponge material, and the airtight material 17 is provided on the outdoor surface of the wall assembly and the airtight material 18 is provided on the side surface or the upper and lower surfaces of the wall assembly with the installation of the panel 11. Each abuts to allow air tightness between the panel and the wall assembly. Note that in FIG.
Is an airtight tape stuck around the indoor side of the panel (inner plate). Further, the fixing of the panel 11 to the wall assembly is performed by using
Nails from outside.

On the other hand, on the inner surface of the outer plate 12 (the portion where the heat insulating layer 16 is formed), a peeling tape 21 that allows the outer plate 12 to be separated from the heat insulating material 16 is attached in advance before the heat insulating layer 16 is formed. Keep it. This is because, when the panel size is changed, the locking portion (12a) can be easily formed at the cut portion.

The change of the panel size (for example, height) is specifically performed as follows. As shown in FIG. 3, the panel 11 is cut along the line AA, for example, so as to have a desired height. When the panel is cut, the locking portion (12a) of the cut portion is lost, so it is necessary to form the cut portion. Therefore, as shown in FIG.
From A), only the inner plate 13 and the heat insulating layer 16 are cut by the width of the locking portion (leaving the outer plate 12) (line BB). For cutting, for example, a circular saw may be used. Cut inner plate and heat insulation layer (hatched in Fig. 4)
Is peeled from the outer plate 12 and removed. With the interposition of the release tape 21, the heat insulating layer can be easily separated. Thereby, a new locking portion can be formed in the cut portion C. Cutting surface of newly formed locking part and heat insulation layer (B-
The airtight materials 17 and 18 are supplemented for the (B line portion). It is also possible to change the width in the same manner.

As described above, the size of the present panel can be freely changed by appropriately cutting the panel. Therefore, for example, as shown in FIG.
By setting the heights h ₁ and h ₂ of the lower and upper panels 11b to appropriate dimensions, the installation position of the window opening frame 35 can be shifted in the vertical direction, and the height position of the window 35a can be freely changed. You can do it. Also, as shown in FIG. 6, even for a wall structure having window openings 35b to 35f having various heights and sizes, there is no need to prepare panels having different sizes corresponding to the respective openings in advance. Thus, the panel can be cut efficiently, and the panel construction around the opening 40 to 49 can be performed efficiently.

Since the peeling tape is interposed between the outer plate and the heat insulating layer as described above, the outer plate and the heat insulating layer are firmly adhered to each other even if hard foamed urethane is used for the heat insulating layer. Without these, these are peeled off without difficulty to form a locking part,
It is possible to install a panel around the opening.

The arrangement pattern of the peeling means (tape 21) is not necessarily limited to the illustrated example. For example, it is also possible to provide a peeling means in a net shape or a grid shape, or to attach a tape at an appropriate interval in an oblique direction. Also, as described above, it is difficult to dispose the peeling tape horizontally (in a polka dot shape) or at an appropriate interval horizontally. In the latter case, the upper end of the heat insulating layer (B-
(B line) just comes to the tape position, the upper end of the heat-insulating layer is easily peeled off at the time of construction, which makes it unstable.) Is possible from

However, as in the above embodiment, the peeling means may be provided at appropriate intervals in the vertical direction, more specifically, so that the tape width W (FIG. 3) is, for example, 3 cm and the tape interval S is, for example, 1 cm. In addition, it is possible to obtain a good result that the heat insulating layer can be easily peeled off and the engaging portion can be formed regardless of the cutting position (particularly the height position) regardless of the cutting position (particularly the height position) without impairing the integrity of the panel.

Further, the presence or absence of the core material (reinforcement material) and the body edge (interior receiving material), the number of arrangements, and the like can be appropriately changed as necessary, and the present invention is not limited to the above embodiment. . In the embodiment, urethane foam (hard urethane foam) is used for the heat insulating layer. However, it is not prohibited to form a panel using a heat insulating resin other than urethane.
