Description

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

  Corrugated cardboard is sometimes used as a building material because it is easy to handle and work during construction (see, for example, Patent Documents 1 and 2). In Patent Document 1, an interior board is attached to a construction surface with cardboard interposed. Thereby, the vibration is absorbed by the cushioning property of the cardboard, and the sound insulation effect can be enhanced.

  Further, Patent Document 2 discloses that a core material in which a corrugated core is formed of a combustible material is coated with an aluminum foil on the front surface or the back surface of the corrugated sheet, and is nonflammable between the entire coated surface of the core material and the aluminum foil. Non-combustible corrugated cardboard having a heat insulating layer interposed therebetween is disclosed.

In the present embodiment, the core member 11 has a thickness of about 20 mm, and the corrugated board member 20 has a thickness of about 13 mm. The core member 11 and each corrugated cardboard member 20 are bonded to each other in a planar shape (planar adhesion) by 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 region (a portion around the planned cutting region) are separated. It means a state of being integrated and bonded without being separated.

  Further, in the panel 10, a pair of opposing peripheral portions are covered with an aluminum foil 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 a long shape with a U-shaped cross section. The reinforcing member 15 has a length over 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 includes a central portion 15a and end portions 15b connected to the both end portions. have. The central portion 15 a of the reinforcing member 15 covers the end surface of the laminated structure of the core member 11 and the cardboard member 20. The end 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 of the panel 10 on both surfaces. 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 a central concentrated load of 120 kg as a load resistance when the panel length is 1250 mm.

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

Next, the case where the panel 10 of this embodiment is used as a ceiling material is demonstrated using FIG.
FIG. 2A is a perspective view when the ceiling material is viewed from above, and FIG. 2B is a cross-sectional view of the main part at the mounting position of the ceiling material.

As shown in FIG. 2A, a plurality of suspension members 50 are suspended from the ceiling in a separated state. The upper end portion of the suspension 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 suspension material 50. In the present 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 suspension material 50 is sandwiched between the side portions of the two base materials 51 and is fixed by fasteners 52 (bolts and nuts) penetrating through the through holes of the suspension material 50 and the holes of the base materials 51. Yes. 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, a bolt is inserted into the loose hole of the base material 51 and penetrated into the peripheral portion of the panel 10 and fixed.

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

According to this embodiment, the following effects can be obtained.
(1) The panel 10 of the present embodiment includes a plate-like core member 11 made of foamed plastic, and plate-like cardboard members 20 disposed on both surfaces of the core member 11. Since the foamed plastic is stronger and lighter than the cardboard, the load resistance of the panel 10 can be increased. Furthermore, since the foamed plastic has water resistance, even when one surface of the panel 10 gets wet, the penetration to the other surface can be suppressed. Moreover, since the foamed plastic can be processed in the same manner as the cardboard, the workability of the panel 10 can be ensured.

  (2) As for the panel 10 of this embodiment, the core member 11 and the corrugated cardboard member 20 are adhere | attached planarly over the whole surface. Thereby, when the panel 10 is cut by a cutter or the like, the panel 10 can be cut while suppressing the deviation between the core member 11 and each cardboard member 20.

  (3) An aluminum foil 29 is bonded to the surface of the cardboard member 20 of the panel 10 of this embodiment. Thereby, fire resistance can be given to the panel 10 by a nonflammable member.

  (4) The core member 11 of the panel 10 of the present embodiment is made of extruded polystyrene foam. Extruded polystyrene foam has high heat insulation performance, has pressure resistance, is strong against water, and is difficult to absorb moisture, and thus can be a panel having higher durability and fire resistance.

  (5) A reinforcing member 15 is attached to a pair of peripheral portions of the panel 10 of the present embodiment. By having the reinforcing member 15, the effective width | variety with respect to stress can be increased and local bending can be suppressed. Therefore, bending at the end of the panel 10 can be suppressed, and the amount of bending when a load is applied to the panel 10 can be reduced.

  (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.

Moreover, you may change the said embodiment as follows.
The surface of the panel 10 of the above embodiment is covered with the aluminum foil 29 of the corrugated cardboard member 20. A surface protection sheet may be further provided on the surface of the cardboard member 20. Here, as the surface protective sheet, for example, a synthetic resin can be used.

  In the panel 10 of the above embodiment, aluminum foil 29 is bonded to both surfaces of the cardboard member 20. The heat-resistant member of the panel 10 is not limited to the surface of the corrugated board 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 is provided only on the surface side of the panel 10. May be provided. Furthermore, a heat resistant layer may be provided between the intermediate liners 25.

-The panel 10 of the said embodiment provided the reinforcement member 15 in a pair of peripheral part which opposes. The reinforcing members 15 may be provided on all sides of the panel 10.
In the above 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, it is good also as the panel 60 using the reinforcing member 65 divided | segmented into plurality in the full length of the edge | side of the panel 10. As shown in FIG. In this case, it is also possible to arrange so that one boundary b1 and the other boundary b2 of the reinforcing member 65 do not correspond to each other at the pair of opposed peripheral edge 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 amount of deflection. For example, when the plate thickness is reduced (for example, about 0.6 mm), the width W is set to 55 mm or more. Further, 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 deflection may be a value corresponding to the assumed central concentrated load applied to the panel 10 and the panel 10 length. Thereby, the amount of bending can be suppressed within a predetermined value.

-The panel 10 of the said 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 extrusion method polystyrene foam was used for the core member 11 of the panel 10 of the said embodiment. The core member 11 may be made of other materials as long as it is a foamed plastic material.
