Description

The present invention relates to a building panel used as a ceiling material, a wall material, or the like.

Corrugated cardboard may be used as a building material because of its ease of handling during construction and processing (see, for example, Patent Documents 1 and 2). In Patent Document 1, an interior board is attached to a construction surface with a corrugated board interposed. As a result, the cushioning property of the corrugated board absorbs the vibration, and the sound insulation effect can be enhanced.

Further, in Patent Document 2, the corrugated plate-shaped core part is covered with an aluminum foil on the front surface or the back surface of a core material formed of a combustible material, and the non-combustibility is provided between the entire covering surface of the core material and the aluminum foil. The non-combustible corrugated cardboard having the heat insulating layer is disclosed.

Conventionally, in a building such as a factory, work may be performed behind the ceiling. In this case, a panel having a large load resistance is used as the ceiling material. However, a panel having a high load resistance, such as an iron material, generally has a large panel weight and poor workability. Moreover, in the panel used as a ceiling material, the panel may be processed depending on the situation of the site. For example, holes may be formed in the panel at the site, depending on the position of the lighting placed on the ceiling. Here, when the panel is difficult to process, efficient work cannot be realized.

The present invention has been made in view of the above problems, and an object thereof is to provide a panel that is lightweight and has high load resistance and workability.

A panel for solving the above problem is a plate-shaped panel including a plate-shaped core member and plate-shaped corrugated cardboard members arranged on both surfaces of the core member, and the core member is made of foamed plastic. The core member and the corrugated board member are planarly bonded over the entire surface. As a result, since the foamed plastic is used as the core member, it is possible to ensure lightweight, high load resistance, and workability.

-In the panel, the surface of the corrugated board member exposed to the outside is preferably covered with a noncombustible member. Thereby, fire resistance can be improved.

The panel includes a reinforcing member that covers an end surface of the laminated structure of the core member and the corrugated cardboard member, and abuts and holds a pair of panel surfaces adjacent to the end surface. As a result, since the end portion of the panel is held, the amount of bending of the panel can be reduced.

-In the above panel, it is preferable that the core member is made of extruded polystyrene foam. Thereby, in the panel having the corrugated board member, the heat insulation performance, pressure resistance, and water resistance can be secured by the extruded polystyrene foam.

According to the present invention, it is possible to ensure lightweight, high load resistance, and workability.

Hereinafter, one embodiment of the panel will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1A, the panel 10 of this embodiment has a plate shape of, for example, about 2000 mm×about 1250 mm×about 50 mm. The panel 10 is configured by stacking a plate-shaped core member 11 arranged in the center and corrugated cardboard members 20 arranged on both surfaces of the core member 11. The core member 11 of the present embodiment is made of an extruded polystyrene foam (for example, Styrofoam (registered trademark)) of a foamed plastic material. In this embodiment, the core member 11 has a thickness of about 20 mm, and the corrugated cardboard member 20 has a thickness of about 13 mm. The core member 11 and each corrugated cardboard member 20 are adhered in a planar manner (adhesive bonding) over the entire surface with an adhesive member such as a double-sided tape. This planar adhesion means that when the panel 10 is cut from the front surface or the back surface of the panel 10, the core member 11 and the corrugated cardboard member 20 around the cut area (a peripheral portion of the planned cutting area) are separated. It means a state where they are integrated and bonded without being separated.

Further, in the panel 10, a pair of opposing peripheral edge portions are covered with aluminum foils 13, respectively. Further, a reinforcing member 15 is attached to a pair of peripheral portions adjacent to the peripheral portion covered with the aluminum foil 13. The reinforcing member 15 has an elongated shape with a U-shaped cross section. The reinforcing member 15 has a length along the entire length of the side of the panel 10. Specifically, the reinforcing member 15 is formed by bending an iron plate member having a predetermined plate thickness (about 0.8 mm), and has a central portion 15a and end portions 15b connected to both ends thereof. have. The central portion 15a of the reinforcing member 15 covers the end faces of the laminated structure of the core member 11 and the corrugated cardboard member 20. The end portion 15b of the reinforcing member 15 is in contact with the panel surface 10a on the front surface or the back surface of the panel 10 and holds the end portion of the panel 10 on both sides. The width W of the end portion 15b of the reinforcing member 15 of this embodiment is about 40 mm. The width W of the reinforcing member 15 is determined with the central concentrated load of 120 kg as the withstand load when the panel length is 1250 mm.

Next, the configuration of the corrugated board member 20 will be described with reference to FIG.
As shown in FIG. 1B, in the corrugated board member 20 of the present embodiment, two intermediate liners 25 are provided between the two surface liners 21, and the intermediate liner 25 is provided between the surface liner 21 and the intermediate liner 25. A second middle core 27 is arranged between the first middle core 26 and the intermediate liner 25. The surface liner 21, the intermediate liner 25, the first and second cores 26, 27 are made of paperboard, and the first and second cores 26, 27 have a corrugated shape. The wave height of the first center core 26 is about 4.6 mm, and the wave height of the second center core 27 is about 2.6 mm. Further, an aluminum foil 29 as a nonflammable member is adhered to the surface of the surface liner 21 with an acrylic adhesive.

Next, a case where the panel 10 of the present embodiment is used as a ceiling material will be described with reference to FIG.
FIG. 2A is a perspective view of the ceiling material viewed from above, and FIG. 2B is a cross-sectional view of a main part at a mounting position of the ceiling material.

As shown in FIG. 2A, a plurality of suspension members 50 are hung from the ceiling in a separated state. The upper end of the hanging member 50 is fixed to a ceiling support member (not shown).
As shown in FIG. 2B, two base materials 51 are attached to the lower end portion of the hanging material 50. In this embodiment, an angle member having a side surface portion and a horizontal portion is used as the base material 51. The lower end portion of the hanging material 50 is sandwiched between the side surface portions of the two base materials 51, and is fixed by a fastener 52 (bolt, nut) penetrating the through hole of the hanging material 50 and the hole of each base material 51. There is. A plurality of loose holes (not shown) for fixing the panel 10 are formed on the side surface of the base material 51.

Then, the panel 10 is placed on the horizontal portion of the base material 51. In this case, the panel 10 is arranged so that the reinforcing member 15 of the panel 10 bridges the opposing base material 51. Then, the bolts are inserted into the loose holes of the base material 51, penetrate the peripheral edge of the panel 10, and are fixed.

When forming the hole h1 in the panel 10, a necessary portion (planned cutting region) is cut into a predetermined shape by a cutter. Further, the inner peripheral portion of the formed hole h1 is covered with a heat resistant member such as aluminum foil.

According to this embodiment, the following effects can be obtained.
(1) The panel 10 of the present embodiment includes a plate-shaped core member 11 made of foamed plastic, and plate-shaped corrugated cardboard members 20 arranged on both surfaces of the core member 11. Since foamed plastic is stronger and lighter than corrugated cardboard, the load bearing capacity of the panel 10 can be increased. Further, since the foamed plastic has water resistance, even if one surface of the panel 10 gets wet, it is possible to suppress the permeation to the other surface. Further, since the foamed plastic can be processed in the same manner as the corrugated board, the workability of the panel 10 can be ensured.

(2) In the panel 10 of the present embodiment, the core member 11 and the corrugated cardboard member 20 are planarly bonded over the entire surface. Thereby, when the panel 10 is cut with a cutter or the like, it is possible to cut while suppressing the displacement between the core member 11 and each corrugated board member 20.

(3) An aluminum foil 29 is adhered to the surface of the corrugated board member 20 of the panel 10 of the present embodiment. As a result, the panel 10 can be made fire resistant by the non-combustible member.

(4) The core member 11 of the panel 10 of the present embodiment is made of extruded polystyrene foam. The extruded polystyrene foam has a high heat insulating property, has a pressure resistance, is strongly resistant to water and hardly absorbs moisture, and thus can be a panel having higher durability and fire resistance.

(5) Reinforcing members 15 are attached to the pair of peripheral portions of the panel 10 of the present embodiment. The presence of the reinforcing member 15 makes it possible to increase the effective width with respect to stress and suppress local bending. Therefore, it is possible to suppress the bending at the end portion of the panel 10 and reduce the amount of bending when a load is applied to the panel 10.

(6) In the present embodiment, the panel 10 is arranged so that the reinforcing member 15 of the panel 10 bridges the opposing base material 51. Thereby, the four sides of the panel 10 can be held by the base material 51 and the reinforcing member 15, and the bending of the panel 10 can be reduced.

Further, the above embodiment may be modified as follows.
-The surface of the panel 10 of the above embodiment is covered with the aluminum foil 29 of the corrugated board member 20. A surface protection sheet may be further provided on the surface of the corrugated board member 20. Here, as the surface protection sheet, for example, a synthetic resin can be used.

-In the panel 10 of the said embodiment, the aluminum foil 29 was adhere|attached on both surfaces of the cardboard member 20. The heat-resistant member of the panel 10 is not limited to the surface of the corrugated cardboard member 20, but may be at least on the surface of the panel 10. The aluminum foil 29 on the core member 11 side is omitted, and the aluminum foil 29 on only the front surface side of the panel 10 is omitted. May be provided. Further, a heat resistant layer may be provided between the intermediate liners 25.

-The panel 10 of the above-described embodiment is provided with the reinforcing member 15 on the pair of opposing peripheral edge portions. The reinforcing member 15 may be provided on all sides of the panel 10.
Further, in the above-described embodiment, the reinforcing member 15 has a length that extends over the entire length of the side of the panel 10. The length of the reinforcing member 15 is not limited to this.

For example, as shown in FIG. 3, a panel 60 using a reinforcing member 65 divided into a plurality of parts along the entire length of the side of the panel 10 may be used. In this case, it is also possible to arrange so that the one boundary b1 of the reinforcing member 65 and the other boundary b2 do not correspond to each other at the pair of opposing peripheral portions. Thereby, the amount of bending can be reduced at the boundaries b1 and b2 at different positions on both sides.

The plate thickness of the reinforcing member 15 provided on the panel 10 of the above embodiment is about 0.8 mm, and the width W is about 40 mm. The plate thickness and width of the reinforcing member 15 are not limited to this. The width may be determined according to the plate thickness of the reinforcing member 15. In this case, the plate thickness and width can be determined in consideration of the bending amount. For example, when the plate thickness is thin (for example, about 0.6 mm), the width W is set to 55 mm or more. When the plate thickness is increased (for example, about 1.0 mm), the width W can be set to 30 mm or more. Further, the width W of the end portion 15b of the reinforcing member 15 for reducing the amount of bending may be a value corresponding to the assumed central concentrated load applied to the panel 10 and the length of the panel 10. Thereby, the amount of bending can be suppressed within a predetermined value.

-Panel 10 of the above-mentioned embodiment was used as a ceiling material. The panel 10 is not limited to a ceiling material as long as it is a building panel, and may be used as a wall material, for example.
The extruded polystyrene foam was used for the core member 11 of the panel 10 of the above embodiment. Other materials may be used for the core member 11 as long as they are foamed plastic materials.

Next, the technical ideas that can be understood from the above-described embodiments and other examples will be added below along with their effects.
(A) The panel according to any one of claims 1 to 4, wherein the core member and the corrugated cardboard member are bonded to each other in a peripheral region of a planned cutting region.
