BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-shaped composite heat insulating material having a ventilation groove formed on the surface side, and more particularly, to a laminated body of a plate-shaped heat insulating material having a ventilation groove and an exterior material. The present invention relates to a plate-shaped composite heat insulating material.

2. Description of the Related Art A plate-shaped heat insulating material provided with a ventilation groove, which is used as a heat insulating material for a wooden house, is one of the most widely used effective plate heat insulating materials as a method for preventing dew condensation inside a frame by heat insulation of a house. One.

In recent years, attention has been paid to hermetic housing in order to minimize heat loss in the house. For this hermetic sealing, a method of installing a heat insulating material outside a frame called an external heat insulating method is used. Is known to be effective. Therefore, in order to obtain the advantages of both the ventilation method and the external heat insulation method, it is conceivable to use these methods in combination. In addition to the mother house and rafters, a member called a ventilation rafter for forming ventilation grooves is also required in the heat insulating material, which increases the number of steps at the time of construction and takes time and costs. There was such a problem.

In order to solve these problems, conventionally, the surface is covered with a surface material such as waterproof paper, for example.
In addition, there is a plate-shaped heat insulating material made of foamed plastics such as rigid urethane foam having a large number of ventilation grooves formed on the surface. This is to prevent the internal dew condensation of the skeleton by exhausting the indoor humidity through the ventilation groove,
Moreover, the foamed plastics can minimize the heat loss in the room and make the house airtight.
However, in this case, since the surface is covered with a face material such as waterproof paper, it cannot be said that the heat insulating material is necessarily satisfactory in terms of mechanical strength.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional technique. An outer material such as an outer wall material or a base material is provided on the surface of a grooved foamed plastic heat insulating material, and the inner material is provided. It is an object of the present invention to provide a plate-shaped composite heat insulating material in which a ventilation space is formed.

[0006]

SUMMARY OF THE INVENTION The present invention is a laminate of a plate-like heat insulating material and an exterior material, wherein the plate-like heat insulating material comprises at least a foamed plastics layer, and a foamed plastic layer is formed by buckling. The present invention provides a plate-like composite heat insulating material having a ventilation groove, and the exterior material is adhered to the plate-like heat insulating material on the side where the ventilation groove is formed.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, a plurality of slits are formed on at least one surface of a plate-like heat insulating material. after that,
The ventilation grooves are buckled by pressing the slits adjacent to each other with a rotating roll or a convex shape at every other slit.

As described above, since the pressing process is employed instead of the cutting process, generation of dust at the time of grooving can be prevented, and grooving can be performed regardless of in-line or off-line.
In addition, good productivity can be obtained because it can be mechanized, and the structure of the equipment used for groove processing is simple, so maintenance is easy and it can be manufactured with low-cost equipment. Since the exterior material is adhered to the groove forming surface side, it is easier to handle than a plate-shaped heat insulating material having a ventilation groove, is superior in strength, and simplifies construction of the exterior material.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a composite heat insulating material according to an embodiment of the present invention. The ventilation groove forming method of the plate-shaped heat insulating material constituting the plate-shaped composite heat insulating material according to the present invention is performed by a plate heat insulating material S having a foamed plastics layer 10 as shown in FIG.
A plurality of slits 20 are formed on one side S1, and then, as shown in FIG. 2, every other slit 20 adjacent to each other is pressed with a pressing device (rotary roll or convex type) 30 at every other interval, and as shown in FIG. The illustrated ventilation groove 40 is buckled.

As a material of the foamed plastics layer 10, for example, rigid urethane foam, urethane-modified isocyanurate foam, isocyanate-modified urethane foam, isocyanurate foam, phenol foam, epoxy foam, phenol-modified urethane foam, polystyrene foam, etc. are used. In this embodiment, the rigid urethane foam is used.

The thickness of the foamed plastics layer 10 is preferably from 10 to 150 mm, particularly preferably from 15 to 75 mm, and if it is less than 10 mm, it is not possible to secure a predetermined ventilation groove capable of eliminating moisture. On the other hand, since there is no change in the heat loss due to, for example, the area around the sash or the ventilation other than the heat-insulated portion, a heat-insulating material having a thickness exceeding 150 mm is not required.

The plate-shaped heat insulating material S of this embodiment has at least the foamed plastics layer 10 although the face material layers 11 and 12 are laminated on the front and back surfaces of the foamed plastics layer 10. In addition, for example, an intermediate layer (not shown) made of a suitable material may be provided. In addition, face material layer 1
1 and 12 may be provided not only on both sides but also on only one side.
As a material of the facing material layers 11 and 12 of this embodiment, a polyolefin material is used that exhausts indoor moisture to the outside, but does not allow rainwater from outside to enter the interior of the room. Although a nonwoven fabric is used, it is not necessarily limited to this. For example, a polyolefin or polyvinyl polymer film, a metal foil (a simple substance such as an aluminum foil or an iron foil), or a polyolefin film and paper A composite of a polyolefin-based film with paper and aluminum foil,
The material is not limited as long as it has moisture-proof and waterproof properties, such as asbestos paper impregnated with asphalt.

The slit 20 shown in FIG. 1 is a slit cut into a plate-like heat insulating material S using a knife H shown in FIG. 4 such as a knife or a cutter. In this embodiment, as shown in FIG. Although formed on one surface S1 of the plate-shaped heat insulating material S in parallel in the vertical direction, it may be formed on both front and back surfaces or in parallel in the horizontal direction or both in the vertical and horizontal directions. The interval between these slits 20 is 5 to 100 mm, especially 10
The thickness is preferably 30 to 30 mm, and if it is less than 5 mm, the strength of the crest formed by the groove processing is reduced and buckling is likely to occur.
If it exceeds 00 mm, it becomes difficult to form grooves by pressing.

The depth of the slit 20 does not necessarily have to be the same as the depth of the ventilation groove. For example, when a rigid polyurethane foam is used, the pressing force acts as a shearing force, and a groove is formed. Therefore, the depth of the slit 20 is preferably equal to or greater than the depth of the groove, and can be appropriately selected depending on the degree of buckling of the foamed plastic layer. Here, the shape of the ventilation groove can be formed as shown in FIG. 5 or FIG. 6 by selecting the form of the roll 33.

The depth of the ventilation groove is 5 to 30 mm, especially 15
２５25 mm is preferable, and if it is less than 5 mm, there is a problem in air circulation, and the moisture elimination effect is significantly reduced.
The moisture exclusion effect does not change even if the pressure exceeds the limit. Further, although the number of the slits 20 formed is not limited as long as it is two or more, as described above, every other slit 20 adjacent to each other is pressed by the roll pressing device 30 shown in FIG. Is preferably an even number.

The roll pressing device 30 includes a slit 20
This is a pressing device in which the air gap 40 is formed on one surface S1 of the plate-shaped heat insulating material S by crushing the spaces between every other slits. However, the present invention is not necessarily limited to the roll pressing device 30. A convex pressing device (convex type) (not shown) having a plurality of streaky convex portions that can be crushed may be employed. The pressing force may be any value as long as the foamed plastic layer is crushed and permanent deformation remains, and is appropriately selected depending on the material. For example, for rigid polyurethane foam, 1.5 k
g / cm ² or more, preferably 2.0 kg / cm ² or more.

As shown in FIG. 4, a specific heat-insulating material S is produced by applying a stock solution 13 of a foamed plastics layer 10 to an upper surface thereof while continuously moving one face material layer 11 as shown in FIG.
It is discharged by 0 and foamed. On the other hand, the other face material layer 12 is carried into the carry-in conveyor 60 and is carried to the double conveyor 70. The one face material layer 11 is turned upside down during the feeding, and the foamed plastics layer 10 formed on the sheet surface is superimposed on the other face material layer 12, and this is put into the double conveyor 70. The foamed plastics layer 10 is heated and cured while passing through the inside of the double conveyor 70, and at the same time, the three members are firmly joined by the self-adhesive force of the foamed plastics layer 10, and then the blade H A plurality of slits 20 are inserted from the side of the face material layer 11 with the roll, and then, the roll pressing device 30 crushes the slits 20 alternately, so that one side S1 of the plate-shaped heat insulating material S is formed.
It is manufactured by shaping the ventilation groove 40 and then cutting it again by the cutter 80 to a predetermined length.

Next, on one side S1 of the plate-like heat insulating material S,
As shown in FIG. 7, an exterior material such as a plywood, a particle board, a hard board, a hard wood chip cement plate, a siding material, a lath board, and an exterior material 90 as a base material are laminated via an adhesive. In this manner, the plate-shaped composite heat insulating material T manufactured by attaching the exterior material 90 to the ventilation groove forming surface side of the plate-shaped thermal insulation material S has the exterior material 90 side facing the outside and the length of the ventilation groove 40. It is assembled to a shaft set (not shown) with its height direction facing up and down the wall. As described above, the embodiment of the present invention has been described, but the present invention is not limited to this embodiment,
Even changes in the configuration and operation without departing from the gist are included in the present invention.
