  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  A building panel according to an embodiment of the present invention is also called a metal sandwich panel, has fire resistance and heat insulation, and is used as an outer wall, a roof, a partition, or the like of a building such as a building, a warehouse, or a house. be able to.

  As shown in FIG. 1, this building panel 1 is composed of a plate-shaped core material 2 and a pair of metals which are bonded to each other on the plate-shaped core material 2 facing upward in the figure and on the back surface facing downward in the figure. It has plate skins 3 and 4.

  The metal plate outer skins 3 and 4 are formed in a long rectangular shape having a predetermined length dimension. As the metal plate skins 3 and 4, for example, a metal plate such as a 55% aluminum-zinc alloy-plated steel plate or a coated steel plate formed into a predetermined shape by press molding, extrusion molding, roll molding or the like can be used.

  The plate-like core material 2 is configured by connecting a plurality of laminated plates 5 in the longitudinal direction. Each of the laminated plates 5 is configured by laminating and bonding a rectangular reinforcing plate 7 to a heat insulating plate 6 formed into a rectangular plate shape by plastic foam. The plurality of laminated plates 5 are perpendicular to the plate thickness direction so that the adjacent laminated plates 5 face each other at the end portion (end surface) facing the connecting direction in the direction perpendicular to the plate thickness direction of the reinforcing plate 7. The plate-shaped core material 2 having a predetermined length corresponding to the length of the metal plate outer skins 3 and 4 is configured by being connected in a long direction (in the illustrated case, the longitudinal direction of the building panel 1). .

  The adjacent laminated plates 5 are preferably connected by bringing the end portions (end surfaces) of the reinforcing plates 7 facing the connecting direction into contact with each other, but the end portions are opposed to each other with a slight gap therebetween. It can also be connected.

  Adhesion between the plate-like core member 2 and the metal plate outer skins 3 and 4 and adhesion between the heat insulating plate 6 and the reinforcing plate 7 are not particularly limited and can be performed using a known adhesive.

  Although not shown in detail, the plate-like core member 2 can be configured to connect a plurality of laminated plates 5 not only in the longitudinal direction but also in the width direction according to the width of the building panel 1.

  As the plastic foam (foamed plastic) that forms the heat insulating plate 6, various materials such as phenol foam, polyurethane foam, polystyrene foam, polyethylene foam, polypropylene foam, and the like can be used. The heat insulating plate 6 has a configuration in which a surface material such as a woven or non-woven fabric made of synthetic fiber, a glass fiber non-woven fabric, paper, a metal foil, or a plastic film is provided on at least one of the front and back surfaces. You can also The thickness dimension of the heat insulating plate 6 can be set to a desired value based on the heat insulating property required for the building panel 1.

  On the other hand, examples of the reinforcing plate 7 include inorganic boards such as gypsum board, calcium silicate board, calcium carbonate board, slate board, flexible board (fiber reinforced cement board), pearlite cement board, rock wool board, ALC panel, and plywood. Organic boards such as cardboard and various metal plates can be used, and it is particularly preferable to use a gypsum board having fire resistance and high bending performance (bending strength and bending performance). In this case, the thickness dimension of the reinforcing plate 7 can be set to a desired value based on the bending performance, heat insulation, fire resistance, and the like required for the building panel 1.

  Since the reinforcing plate 7 has higher bending performance (bending strength and bending rigidity) than the metal plate outer skins 3 and 4 and the heat insulating plate 6, the plate core 2 is laminated to the heat insulating plate 6 and the reinforcing plate 7 is laminated and bonded. By adopting such a configuration, the bending performance of the building panel 1 can be enhanced.

  The reinforcing plate 7 preferably has a higher surface smoothness and flatness than the heat insulating plate 6 formed of plastic foam. In this case, the plate-shaped core material 2 is configured by laminating and adhering the reinforcing plate 7 to the heat insulating plate 6, thereby smoothing the metal plate outer skin 3 bonded to the surface of the plate-shaped core material 2 on the reinforcing plate 7 side. The aesthetics of this building panel 1 can be enhanced by improving the properties. As described above, since the reinforcing plate 7 has higher surface smoothness and flatness than the heat insulating plate 6, the side on which the metal plate outer skin 3 is bonded to the surface of the reinforcing plate 7 is the surface of the building panel 1. The surface is preferred.

  Furthermore, the fire resistance of this building panel 1 can be enhanced by using a material having fire resistance such as gypsum board as the reinforcing plate 7.

  Although not shown in the figure, the male engaging portion is provided at one short-side end of the building panel 1 facing the direction orthogonal to the connecting direction (longitudinal direction) and the thickness direction, and the other short-side end. It can also be set as the structure which provided the female type | mold engagement part. In this case, the building panel 1 can be connected in the width direction by fitting the male engagement portion to the female engagement portion of another building panel 1. The male engaging portion and the female engaging portion do not need to be configured by the heat insulating plate 6 or the reinforcing plate 7. For example, an organic heat insulating layer is formed by pouring a stock solution between a pair of metal plate outer shells and foaming and curing the solution. Or a heat insulating layer provided between the pair of metal plate outer skins 3 and 4, such as providing an inorganic heat insulating layer by packing a compact between a pair of metal outer skins. Even in such a configuration, since the ratio of the male engaging portion and the female engaging portion to the entire building panel 1 is small, there is little adverse effect on the fire resistance and heat insulating property of the building panel 1. In addition, although not shown in the drawings, attachment portions for attaching the building panel 1 to a building can be provided at both ends in the connecting direction (longitudinal direction) of the building panel 1. In addition, the code | symbol 10 is the heat insulation layer 10 for filling the clearance gap in the edge part of the longitudinal direction of the panel 1 for construction.

  As shown in FIG. 2A, a rigid plate 12 straddles the seam portion 11 from the side where the heat insulating plate 6 is disposed on the seam portion 11 facing (abutting) between a pair of adjacent reinforcing plates 7. Is glued. That is, the joint portion 11 of the pair of adjacent reinforcing plates 7 is backed by the rigid plate 12.

  As the rigid plate 12, one having a bending performance higher than that of the reinforcing plate 7 is used. For example, as the rigid plate 12, a plate material made of the same material as the reinforcing plate 7 such as a plaster board can be used. In this case, the rigid plate 12 is preferably thicker than the reinforcing plate 7, but may have the same thickness as the reinforcing plate 7. Further, the rigid plate 12 is formed in a plate shape extending over the entire length of the joint portion 11 along the joint portion 11 of the pair of adjacent reinforcing plates 7 so as to cover the entire joint portion 11. It is preferable.

  The rigid plate 12 is not limited to a plaster board, and various organic boards and metal plates can be used as long as they have a bending performance higher than that of the reinforcing plate 7. Further, the length dimension of the rigid plate 12 in the connecting direction is preferably 4 times or more the thickness of the reinforcing plate 7 and more preferably 8 times or more.

  In this way, in the building panel 1 using a structure in which a plurality of laminated plates 5 are connected as the plate-shaped core member 2, the joint portion 11 of the adjacent reinforcing plate 7 is straddled across the joint portion 11. By bonding the rigid plate 12 having a bending performance higher than that of the reinforcing plate 7, the joint portion 11 of the reinforcing plate 7 is reinforced by the rigid plate 12, and the bending performance (bending of the plate-like core material 2 or the building panel 1 is bent). Strength and bending rigidity).

  Further, since the joint portion 11 of the reinforcing plate 7 is closed from the back side by the rigid plate 12, when a material having fire resistance such as a plaster board is used as the rigid plate 12, it is laminated. The rigid plate 12 prevents flames and heat from passing through the connecting portions of the plates 5 to the front and back of the building panel, and the fire resistance of the building panel 1 can be improved.

  Adhesion between the rigid plate 12 and the reinforcing plate 7 is not particularly limited and can be performed using a known adhesive. In this case, it is preferable to use the same type of adhesive for bonding the rigid plate 12 to the reinforcing plate 7 and the adhesive for bonding the reinforcing plate 7 to the metal plate outer skin 3. Thus, in manufacturing the building panel 1, the step of bonding the reinforcing plate 7 to the metal plate outer skin 3 is performed, and then the step of bonding the rigid plate 12 to the joint portion 11 of the adjacent reinforcing plate 7 is performed. Since the same type of adhesive can be used in these steps, these steps can be facilitated to increase the productivity of the building panel. In this case, for example, the rigid plate 12 and the reinforcing plate 7 are used as an adhesive that bonds the ends of the pair of reinforcing plates 7 that abut each other or an adhesive that bonds the ends of the pair of heat insulating plates 6 that abut each other. It is also possible to use the same type of adhesive as that for adhering to each other.

  As shown in FIG. 1, the reinforcing plate 7 is formed such that the length dimension of the laminated plate 5 in the connecting direction is longer than the length dimension of the heat insulating plate 6 in the connecting direction. It is preferable that projecting portions 13 projecting in the connecting direction with respect to the heat insulating plate 6 are integrally provided on both sides in the direction. In this case, the pair of adjacent reinforcing plates 7 oppose or abut each other at the protruding portion 13, and the rigid plate 12 is bonded across both of the pair of protruding portions 13.

  According to this configuration, a backing space for adhering the rigid plate 12 to the joint portion 11 of the reinforcing plate 7 is secured between the heat insulating plates 6 of the pair of adjacent laminated plates 5. The work of bonding the plate 12 to the joint portion 11 of the reinforcing plate 7 can be facilitated, and the productivity of the building panel 1 can be further enhanced.

  As shown in FIG. 2 (a), a structure in which a sub heat insulating plate 14 formed of plastic foam is overlapped and bonded to the back surface which is the surface opposite to the side bonded to the protruding portion 13 of the rigid plate 12. can do. As the plastic foam forming the auxiliary heat insulating plate 14, it is preferable to use the same material as the heat insulating plate 6, but it is also possible to use a material different from the heat insulating plate 6. Moreover, it is preferable to use the same type of adhesive as that for adhering the sub-heat insulating plate 14 to the rigid plate 12 and the adhesive for adhering the rigid plate 12 to the reinforcing plate 7, thereby improving the productivity of this building panel. Can be increased.

  The plate thickness of the sub heat insulating plate 14 is preferably set to a thickness obtained by subtracting the plate thickness of the rigid plate 12 from the plate thickness of the heat insulating plate 6. That is, it is preferable that the total thickness of the plate thickness of the rigid plate 12 and the plate thickness of the auxiliary heat insulation plate 14 be equal to the plate thickness of the heat insulation plate 6. In the case of such a configuration, a space for backing the rigid plate 12 is secured between a pair of heat insulating plates 6 of adjacent laminated plates 5, and is arranged in the same plane as the surfaces of the pair of heat insulating plates 6. The smoothness of the surface of the metal plate outer skin 4 can be increased by the surface of the auxiliary heat insulating plate 14.

  In the above configuration, it is preferable to set the length dimension of the rigid plate 12 in the connecting direction to be equal to the sum of the length dimensions of the pair of adjacent projecting portions 13 in the connecting direction. In this case, it is preferable that the central position of the rigid plate 12 in the connecting direction and the position where the adjacent pair of protrusions 13 face or abut each other coincide. Further, in this case, the length dimension of the auxiliary heat insulating plate 14 in the connecting direction is set equal to the total length dimension of the pair of adjacent projecting portions 13 in the connecting direction, that is, the length dimension of the rigid plate 12. It is preferable to do this. In such a configuration, the auxiliary heat insulating plate 14 abuts against the pair of heat insulating plates 6, that is, the pair of adjacent backing laminates 15 in which the rigid plate 12 and the auxiliary heat insulating plate 14 are integrated. Are bonded in a state of being fitted between the heat insulating plates 6, so that a pair of adjacent heat insulating plates 6 are integrated via the backing laminate 15, and the plate-like core material 2 is bent. The performance can be further enhanced.

  The auxiliary heat insulating plate 14 has a configuration in which the deformation amount when receiving a predetermined load in the plate thickness direction is larger than the deformation amount of the heat insulating plate 6 when receiving a predetermined load in the plate thickness direction. It is preferable to use it.

  The sub heat insulating plate 14 having such a configuration is formed of, for example, a plastic foam having a lower elastic modulus (Young's modulus) than that of the heat insulating plate 6, or is formed of the same material as the heat insulating plate 6, but has a slit or a cross section partially. It can be obtained by providing a part that is easily elastically deformed, for example, by providing a part that has been lost, or by combining these parts. The sub heat insulating plate 14 is preferably formed of the same material as the heat insulating plate 6 in consideration of adhesion stability, heat insulating properties, stretchability, and the like.

  As described above, the sub heat insulating plate 14 can be easily deformed in the thickness direction as compared with the heat insulating plate 6, so that the rigid plate 12 and the sub heat insulating plate 14 are overlapped and bonded due to an error or the like generated in the manufacturing process. Even when the thickness dimension of the backing laminate 15 having the above-described configuration is larger than the thickness dimension of the heat insulating plate 6, the metal plate outer shell 4 is bonded to the heat insulating plate 6 in the step of bonding the metal plate outer shell 4 to the plate-like core member 2. When pressed against the surface, the auxiliary heat insulating plate 14 is deformed to be larger than that of the heat insulating plate 6 by the load, and the surfaces can be made flush with each other. Therefore, the thickness error of the sub heat insulating plate 14 with respect to the heat insulating plate 6 can be absorbed, and the smoothness or flatness of the surface of the metal plate outer skin 4 can be maintained.

  The rigid plate 12 is not limited to the configuration in which the auxiliary heat insulating plate 14 is bonded to the back surface thereof, but can also be configured to have the same thickness as the heat insulating plate 6 as shown in FIG. In this case, the space between the pair of heat insulating plates 6 can be filled with the rigid plate 12 alone, and the same effect as the one-sided laminated body 15 described above can be produced.

  As shown in FIG. 3A, the plurality of laminated plates 5 can be configured such that the reinforcing plate 7 is bonded to the heat insulating plate 6 in advance before being bonded to the metal plate outer skins 3 and 4. In this case, in the manufacturing process of the building panel 1, the laminated plate 5 formed by bonding the reinforcing plate 7 to the heat insulating plate 6 in advance on the upper surface of the one metal plate outer skin 3 arranged on the work table or the like is sequentially elongated. They will be glued side by side in the direction.

  Thus, by previously laminating and integrating the heat insulating plate 6 and the reinforcing plate 7, the number of manufacturing steps of the building panel 1 can be reduced and the productivity of the building panel 1 can be increased. In particular, the adhesive for adhering the laminated plate 5 to the metal plate outer skin 3 is of a different type from the adhesive for adhering the reinforcing plate 7 to the heat insulating plate 6, or the heat insulating plate 6 and the reinforcing plate 7 are bonded. When these need to be pressurized and heated, the productivity of the building panel 1 can be increased more effectively. In addition, even when the manufacturing process of the building panel 1 is highly apparatusized, it is sufficient to provide a single device for loading the metal plate skins 3 and 4 as a plate loading device. The productivity of the panel 1 can be increased more effectively.

  Similarly, the backing laminate 15 can also have a configuration in which the auxiliary heat insulating plate 14 is bonded to the rigid plate 12 in advance. In this case, in the manufacturing process of the building panel 1, the sub heat insulating plate 14 is preliminarily attached to the rigid plate 12 in the space between the pair of heat insulating plates 6 of the adjacent laminated plates 5 bonded to the upper surface of the metal plate outer skin 3. The backing laminate 15 having a bonded structure is disposed, and the rigid plates 12 constituting the backing laminate 15 are adhered to the joint portion 11 of the protruding portion 13 that abuts each other.

  In the configuration in which the auxiliary heat insulating plate 14 is bonded integrally to the rigid plate 12 in advance, after the auxiliary heat insulating plate 14 having the same thickness as the heat insulating plate 6 is bonded to the rigid plate 12 in advance, the thickness of the auxiliary heat insulating plate 14 is changed to the rigid plate. Processing may be performed to reduce the thickness by 12 or the sub heat insulating plate 14 that has been previously thinner than the heat insulating plate 6 by the amount corresponding to the rigid plate 12 may be bonded to the rigid plate 12.

  In this way, by rigidly integrating the rigid plate 12 and the sub heat insulating plate 14 in advance, the number of manufacturing steps and the number of parts of the building panel 1 are reduced, and the productivity of the building panel 1 is increased. be able to. In particular, the rigid plate 12 and the auxiliary heat insulating plate 14 are bonded with an adhesive different from the adhesive for bonding the laminated plate 5 to the metal plate outer skin 3 or the adhesive for bonding the heat insulating plate 6 and the reinforcing plate 7. In the case where the rigid panel 12 and the auxiliary heat insulating plate 14 are bonded, when the pressure and heating are necessary for these, the productivity of the building panel 1 can be increased more effectively.

  In order to increase the productivity of the building panel 1 more effectively, as shown in FIG. 3 (b), a laminated plate 5 having a configuration in which a reinforcing plate 7 is bonded to a heat insulating plate 6 in advance is formed. It is also possible to configure the core component 16 in which the rigid plate 12 is bonded in advance to one projecting portion 13 of the reinforcing plate 7. In this case, half of the rigid plate 12 is bonded to the surface of the one protruding portion 13 on the side where the heat insulating plate 6 is arranged, and the other half is bonded to the protruding portion 13. With such a configuration, in the manufacturing process of the building panel 1, the core component 16 having a configuration in which the rigid plate 12 is bonded to the laminated plate 5 in advance on the upper surface of one metal plate outer skin 3 disposed on a work table or the like. Are sequentially aligned in the longitudinal direction and bonded, whereby the laminated plate 5 is bonded to the metal plate outer skin 3 and the rigid plate 12 is bonded to the joint portion 11 of the protruding portion 13 of the adjacent laminated plate 5. Since it can carry out by one process, the number of manufacturing processes of this building panel 1 can be reduced, and the productivity of the building panel 1 can be increased.

  Even in the case shown in FIG. 3B, the rigid heat insulating plate 14 may be integrated with the rigid plate 12 in advance. In this case, the number of manufacturing steps and the number of parts of the building panel 1 can be reduced, and the productivity of the building panel 1 can be further increased.

  In addition, as shown in FIG.3 (c), the several laminated board 5 does not set it as the structure by which the reinforcement board 7 was previously adhere | attached on the heat insulation board 6, but in the manufacturing process of the building panel 1, it is a work table. Alternatively, the reinforcing plate 7 may be bonded to the upper surface of one of the metal plate outer shells 3 that are arranged in the same manner, and the heat insulating plate 6 may be bonded to the reinforcing plate 7 after that. In this case, the rigid plate 12 may have a configuration in which the auxiliary heat insulating plate 14 is bonded in advance, but the rigid plate 12 and the auxiliary heat insulating plate 14 may be bonded in separate steps.

  FIG. 4 is an enlarged cross-sectional view showing the connection structure of laminated plates in a modification of the building panel shown in FIG. In FIG. 4, members corresponding to those described above are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 4 as a modified example, each of the plurality of laminated plates 5 includes one heat insulating plate 6 and a pair of reinforcing plates 7 that are laminated and bonded to both surfaces of the heat insulating plate 6 in the thickness direction. It can also be set as the structure provided. Also in this modified example, each of the pair of reinforcing plates 7 is configured such that the length in the connecting direction is longer than the length of the heat insulating plate 6 in that direction, and the protrusions 13 are provided at both ends thereof. Can do. In this case, the adjacent laminated plates 5 have the protruding portions 13 of the reinforcing plate 7 bonded to the surface on one side in the thickness direction of the heat insulating plate 6 opposed to or in contact with each other, and the other side in the thickness direction of the heat insulating plate 6. The protrusions 13 of the reinforcing plate 7 bonded to the surface of the reinforcing plate 7 are connected to each other in the longitudinal direction so as to face or abut each other.

  In this modified example, the rigid plate 12 straddles the joint portion 11 from the side where the heat insulating plate 6 is disposed at the joint portion 11 of the protruding portion 13 that contacts each other on one side in the thickness direction of the heat insulating plate 6. The rigid plate 12 is bonded to the joint portion 11 of the projecting portion 13 that is bonded to the other side in the thickness direction of the heat insulating plate 6 from the side where the heat insulating plate 6 is disposed across the joint portion 11. Is done. As described above, in this modification, the reinforcing plates 7 are provided on both sides in the thickness direction with the heat insulating plate 6 interposed therebetween, and the joint portions 11 of the reinforcing plate 7 are reinforced by the rigid plates 12 on both sides. The bending performance of the core material 2, that is, the building panel 1 can be further enhanced. In particular, since the reinforcing plates 7 are disposed on both sides of the heat insulating plate 6, it is possible to enhance the bending performance with respect to both the bending toward the front surface side and the bending toward the back surface side of the building panel 1. .

  Also in this modified example, the pair of rigid plates 12 can be configured such that a sub heat insulating plate 14 formed of plastic foam is adhered therebetween. As the plastic foam forming the auxiliary heat insulating plate 14, it is preferable to use the same material as the heat insulating plate 6, but it is also possible to use a material different from the heat insulating plate 6. The thickness of the sub heat insulating plate 14 is preferably set to a thickness obtained by subtracting the thickness of the pair of rigid plates 12 from the thickness of the heat insulating plate 6. That is, it is preferable that the total thickness of the pair of rigid plates 12 and the sub heat insulating plate 14 be equal to the plate thickness of the heat insulating plate 6.

  Also in the case of the modification shown in FIG. 4, as shown in FIG. 5, the plurality of laminated plates 5 can have a configuration in which a pair of reinforcing plates 7 are bonded to a heat insulating plate 6 in advance. Further, the pair of rigid plates 12 can be configured in advance as one backing laminate 15 by adhering the auxiliary heat insulating plate 14 between them. In this case, in the manufacturing process of the building panel 1, the laminated plate 5 configured by previously bonding a pair of reinforcing plates 7 to the heat insulating plate 6 on the upper surface of one metal plate outer skin 3 disposed on a work table or the like. Are adhered side by side in the longitudinal direction. Then, the backing laminate 15 in which the rigid plate 12 is bonded to both surfaces of the auxiliary heat insulating plate 14 is inserted and bonded in a short and real manner between the pair of protrusions 13 of the adjacent laminate 5. Thus, on both sides of the heat insulating plate 6, the joint portions 11 of the protruding portions 13 of the adjacent reinforcing plates 7 are backed by the rigid plates 12.

  In this modified example, on one side in the connecting direction of the laminated plates 5, the backing laminated body 15 may be fitted and bonded in advance between the pair of protruding portions 13. Thereby, the fitting operation | work of the backing laminated body 15 between a pair of protrusion parts 13 can be simplified, and the productivity of this building panel 1 can further be improved.
