Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a panel material that can be used as architectural wall material, floor material, etc.

[Background Art] Panel materials containing synthetic resin foam molding materials have a heat insulating effect and are therefore widely used as architectural interior materials, walls, floors, roofing materials, partitions, doors, and furniture materials.

This panel material generally has a structure in which a synthetic resin foam is filled into a core material of a honeycomb structure, and surface materials are fixed to both sides of the core material (see Japanese Patent Application Laid-Open No. 58-3861). .

In this panel material, the synthetic resin foam within the honeycomb structure has a heat insulating effect, and the honeycomb structure and the surface material maintain their strength.

However, this panel material with a honeycomb structure requires large-scale manufacturing equipment, making it difficult to uniformly fill the honeycomb structure with foam, which can cause unevenness on the surface material and deformation (warp) due to expansion and contraction of the foam. becomes.

For this reason, a panel material in which only a portion of the honeycomb structure is filled with foam has been proposed. JP-A-57-1874
No. 55). However, even in this case, it is not possible to eliminate the unevenness that occurs on the surface material and the deformation (warpage) of the panel material, and the strength and heat insulation properties are lower than that of a panel material that is filled without any gaps inside the honeycomb structure.

[Object of the invention] Taking the above facts into consideration, the present invention is lightweight and has high strength,
Moreover, the objective is to obtain a panel material with high heat insulation properties.

[Structure of the Invention] The panel material according to the present invention is obtained by cutting a laminated panel with a face material attached to at least one side of a core material into strips to form a unit body, and then cutting the unit body into strips between adjacent unit bodies. They are connected in a plate shape with the materials sandwiched between them. Therefore, there is no need to fill the honeycomb structure with a foamed material or the like, thereby eliminating a decrease in strength due to insufficient filling and providing high heat insulation properties.

[Embodiment of the Invention] FIG. 1 shows a panel material 10 according to a first embodiment of the invention, and the panel material 10 has a plurality of units 12. These units 12 have thin face members 16 fixed to both sides of a core member 14 having a rectangular cross section. These face materials 16 are arranged to be sandwiched between adjacent unit bodies 12 and fixed with an adhesive or the like, so that the panel material 10 as a whole has a plate shape.

The core material 14 is a composite of hard urethane foam, incyanurate foam, phenol foam, etc.
Alternatively, an inorganic material having a heat insulating effect such as glass wool can be used. The facing material 16 is paper, asbestos paper, aluminum foil,
Although wood, iron plate, etc. can be used, it is preferable to use a material that is lightweight and has high strength.

FIG. 2 shows a laminated panel 18 for manufacturing the panel material 10 of FIG. This laminated panel 18 is constructed by adhesively laminating face materials 16 on the front and back surfaces of a plate-shaped core material 14, respectively. After stacking a plurality of laminated panels 18, the laminated panels 18 are cut into strips as shown by arrow A. The panel material 10 shown in FIG. 1 is obtained by rotating the thus cut strip-shaped portion by 90 degrees. That is, the first
Panel material 1 consisting of six units 12 as shown in the figure
0, the laminated panel 1 shown in FIG.
8 can be made by stacking six sheets and cutting them into strips.

FIG. 12 shows a manufacturing apparatus and procedure for manufacturing the laminated panel 18 of FIG. 2. The lower material 16A is guided to the cutter 104 on the heating table lOO and the lower belt conveyor 102, and the upper material 16B is guided to the cutter 104 on the heating table lOO and on the lower belt conveyor 102.
It is guided to the lower surface of the heating table 100 and separated from the lower surface material on the heating table 100, but after being guided to the lower surface of the upper belt conveyor 108 and approaching the lower surface material 16A, it is guided to the cutter 104.

The foamed material from the low-pressure foam @110 is foamed from the nozzle 112 onto the bottom material 16A on the heating table 100, and is transferred between the top and bottom belt conveyors 108 and 102 to the top and bottom materials 16B and 16A.
move with Here, this upper and lower belt conveyor 108
．． The laminated panel 18 is formed by pressure molding at 102 and cut by a cutter 104. Therefore, the unit body 12 manufactured by this procedure is in the longitudinal direction of the foamed material (the parallel direction of foaming).
is perpendicular to the face material 16.

In this way, the panel material 10 of this embodiment can be manufactured by simply cutting the laminated panel 18 into strips, and since the face material 16 prevents the core material 14 from deforming, the panel material 10 is lightweight and has high strength.
0 can be produced.

Although it is possible to apply adhesive over the entire surface of the plurality of laminated panels 18 shown in FIG. 2 between adjacent panels 16, as shown in FIG. Other adhesive means, such as providing only the adhesive surface 19, can also be employed. As the adhesive, various types such as urethane type, epoxy type, rubber type, phenol type, melanin type, urea type, etc. can be used.

FIG. 4 shows a panel material 20 according to a second embodiment of the present invention. This panel material 20 is a composite board in which face materials 22 are fixed to the front and back surfaces of the panel material 10 of the above embodiment. This surface material 22 can be made of plywood, iron plate, gypsum board,
A synthetic resin board etc. can be used. This face material 22 can completely prevent deformation of the panel material 10.

FIG. 5 shows a third embodiment of the invention. In each of the above embodiments, the unit body 12 was in close contact with the adjacent unit body 12, but in this embodiment, the unit body 12
are arranged with a gap 24 between them and adjacent unit bodies 12. Therefore, the manufacturing procedure shown in FIG. 2 cannot be applied to the unit body 12 of this embodiment, and the unit body 12 is
2 will be glued and attached sequentially.

Incidentally, it may be arranged between the unit bodies 12 in a direction intersecting another unit body 12 in a protruding shape. In this case, unit 1
Another unit to be placed between the two units may be cut to the size between the adjacent units, or a long unit may be joined to the unit 12 by notches.

FIG. 6 shows a panel material 26 according to a fourth embodiment of the present invention. The panel material 26 of this embodiment has a structure in which the panel material units of the second embodiment shown in FIG. 4 are superimposed in the orthogonal direction. Therefore, the anisotropy is improved and warping during thermal deformation is significantly reduced.

FIG. 7 shows a panel material 2B according to a fifth embodiment of the present invention. In this panel material 28, the shape of the face material is different from that of the second embodiment shown in FIG. The face material 30 of this embodiment has a U-shaped rib 32 formed in the middle part,
The inside of the rib 32 becomes an air layer. This air layer not only improves the heat insulation effect but also serves as an escape route for combustion gas and has a fire prevention effect.

Further, FIG. 8 shows a sixth embodiment of the present invention. In this embodiment, the panel material 2 of the second embodiment shown in FIG.
0 is inserted into the rectangular reinforcing frame 34,
It is advantageous in terms of strength. Therefore, the panel material 36 of this embodiment
is particularly suitable for manufacturing furniture, etc.

Next, FIG. 9 shows a manufacturing procedure different from the first embodiment shown in FIG. 2. That is, cut lines 3 are cut alternately from the front and back surfaces of the laminated panel 18 formed in the same manner as in the first embodiment.
Enter 8. This cut line 38 does not completely cut the laminated panel 18, but forms a connecting portion 40 in which at least the face material 16 remains near the front and back surfaces.

Thereafter, the cut laminated panel is bent around the connecting portion 40, and the panel members 16 bent in a U-shape around the connecting portion 40 are adhered to each other to form a panel material 42.

Next, dimensional changes when a synthetic resin foam is used as the core material 14 of the panel material using the present invention will be explained.

As shown in FIG. 10, the dimensional stability against temperature changes due to the effect of the cell structure of the synthetic resin varies significantly depending on the direction of foaming. That is, as shown in FIGS. 11(A) and 11(B), the longitudinal direction of the cells of the foam material is the foaming parallel direction,
Thermal deformation in this direction is significantly smaller than that in the direction perpendicular to foaming. Therefore, in the case of a general laminated panel 18 manufactured by the manufacturing procedure shown in FIG. ) As shown in the figure, the panel material 1 is placed so that the width direction of the panel material (left-right direction in FIG. 11) is parallel to the foaming direction.
6 adjacently, the length direction of the panel material (the 11th
Expansion and contraction in the direction perpendicular to the plane of the drawing (A) and in the width direction can be significantly suppressed. Conversely, in the thickness direction (Fig. 11 (
Although the thermal deformation in the A) vertical direction increases, since the face material 16 has the role of suppressing the expansion and contraction of the core material 14, it is possible to obtain a panel material with small thermal deformation as a whole.

It goes without saying that the present invention is not limited to the foaming direction shown in FIG. 11, but can also be applied to the case where the foaming direction is the opposite direction.

Further, in each of the above embodiments, the structure in which the laminated panel 18 for creating the unit body 12 is flat is shown, but this laminated panel may have a bent shape such as a corrugated shape.

[Effects of the Invention] As explained above, the panel material according to the present invention is lightweight and has high strength because the unit bodies cut into strips from the laminated panel are connected in a plate shape by sandwiching the face material between adjacent units. It is possible to obtain a panel material with high heat insulation properties, and the dimensional change is small, making it suitable for construction materials such as furniture.
