[Effects of the Invention]
[0009] According to the present invention, on-site work at construction sites can be simplified. [Brief explanation of the drawing]
[0010] [Figure 1] This figure illustrates the configuration of the building panel 1 in the embodiment. [Figure 2] This diagram illustrates a surface structure with building panel 1 attached. [Figure 3] This is a flowchart illustrating the installation method (S10) for building panel 1. [Modes for carrying out the invention]
[0011] Embodiments of the present invention will be described below with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples. Figure 1 is a diagram illustrating the configuration of the building panel 1 in an embodiment. Figure 1(A) is a diagram illustrating the building panel, and Figure 1(B) is a cross-sectional view illustrating the building panel. As illustrated in Figures 1(A) and 1(B), the building panel 1 comprises an insulating material 10, a gypsum board 20, a viscoelastic member 30, and an adhesive 50. The building panel 1 is formed by bonding gypsum board 20, which has been pre-cut in advance at a factory or other location other than the construction site based on the design information of the house, to insulation material 10, which has also been pre-cut in a factory or other location other than the construction site based on the design information of the house, at bonding positions based on the design information of the house. Here, the design information of the house refers to drawing data of structural drawings that show the structural members of the building, such as columns, girders, beams, rafters, roof trusses, and ridge beams, and includes, for example, information on the distance between two structural members (span length), or dimensional information of the space enclosed by the structural members.
[0012] The insulation material 10 is an insulation material formed from foamed synthetic resin into a plate shape. The insulation material 10 is a foamed plastic insulation material, such as polystyrene foam, phenolic foam, or rigid polyurethane foam. In this example, the insulation material 10 is phenolic foam from the viewpoint of thermal insulation and flame resistance. The insulation material 10 is pre-cut in advance at a factory or other location outside the construction site, and is cut to the size (dimensions) and shape according to the design information of the house. The insulation material 10 is pre-cut to a size smaller than the gypsum board 20, specifically, the surface area of the insulation material 10 is pre-cut to be smaller than the surface area of the gypsum board 20. Furthermore, the insulation material 10 is bonded to the bonding position corresponding to the design information of the house, and is bonded to the inside of the outer edge of the gypsum board 20. Note that the insulation material 10 is an example of an insulation board according to the present invention.
[0013] Gypsum board 20, also known as plasterboard, is a board-shaped building material primarily composed of gypsum. Specifically, gypsum board 20 is a building material for interior or exterior use, consisting of a board-shaped core material primarily composed of gypsum covered with gypsum board paper. Gypsum board 20 is a base gypsum board used for walls and ceilings of buildings, and is, for example, a structural gypsum board (Type A, Type B), gypsum board, or reinforced gypsum board as specified in JIS A 6901 (Gypsum Board Products). Gypsum board 20 is an inorganic load-bearing surface material and is installed as a surface material for load-bearing walls. In addition, gypsum board 20 has functions such as fire resistance, earthquake resistance, high water resistance, and high mold resistance. Furthermore, the gypsum board 20 is pre-cut in advance at a factory or other location other than the construction site, and is cut (processed) to the size (dimensions) and shape according to the design information of the house. The gypsum board 20 is pre-cut to a size larger than the insulation material 10, specifically, the surface area of the gypsum board 20 is pre-cut to be larger than the surface area of the insulation material 10. The gypsum board 20 is an example of the gypsum board according to the present invention.
[0014] The viscoelastic member 30 is an example of a viscoelastic member according to the present invention, and is a tape material that is adhesive and elastic, and is installed on the surface of a gypsum board 20 to which the insulation material 10 is not adhered. The viscoelastic member 30 is, for example, made of a butyl rubber-based material in the shape of a tape, and has adhesive layers on both sides thereof. The viscoelastic member 30 is located between the gypsum board 20 and the building frame when the gypsum board 20 is installed on the building frame of the house. Furthermore, the width of the viscoelastic member 30 is, for example, 30 mm or more and 100 mm or less. Also, the thickness of the viscoelastic member 30 is, for example, 5 mm or less and 1 mm or more and 3 mm or less.
[0015] The adhesive 50 is used to bond pre-cut insulation material 10, which is also pre-cut based on the house design information, to pre-cut gypsum board 20, which is also pre-cut based on the house design information. The adhesive 50 is, for example, a hot-melt adhesive. For example, if the adhesive 50 is a non-reactive hot-melt adhesive, it is an EVA resin-based, synthetic rubber-based, polyamide-based, or polyester-based adhesive, and if it is a reactive hot-melt adhesive, it is a PUR (urethane resin reaction)-based or POR (olefin resin reaction)-based adhesive. The adhesive 50 can be appropriately selected as either non-reactive or reactive.
[0016] Figure 2 illustrates a wall structure with building panel 1 attached. Figure 2(A) is an example of the internal structure of a load-bearing wall, and Figure 2(B) is an enlarged view illustrating the internal structure. As illustrated in Figures 2(A) and 2(B), the building panel 1 is installed, for example, as a shearing material for a load-bearing wall in a large-wall construction method. The building panel 1 may be installed as a shearing material for a large-wall construction method or as a shearing material for a traditional Japanese wall construction method. In this example, the building panel 1 is a shearing material for a large-wall construction method. The building panel 1 is installed on the structure of the house from the exterior side to the interior side. Specifically, the building panel 1 is installed so that the gypsum board 20 is located on the exterior side and the insulation material 10 is located on the interior side. The building panel 1 is installed so that the insulation material 10 fits into the space formed by the columns (including studs), beams, or girders that constitute the structure of the house, and the gypsum board 20 covers the framework of the columns, beams, or girders. The viscoelastic member 30 is located between the gypsum board 20 and the column or stud when the gypsum board 20 is installed on the structure of the house, and is bonded to the gypsum board 20 and the column or stud. For example, when a house shakes due to an earthquake or the like, columns and beams deform while maintaining a predetermined angle, whereas the gypsum board 20 does not deform, so a relative displacement occurs. However, since the viscoelastic member 30 can reduce this displacement, it is possible to prevent bending and pulling out of nails and screws that fix the gypsum board 20.
[0017] FIG. 3 is a flowchart for explaining a manufacturing method (S10) of the building panel 1. As illustrated in FIG. 3, in step 100 (S100), an operator, for example, at a processing factory, cuts (precuts) the gypsum board 20 into a size (dimension) and shape corresponding to the housing design information based on the housing design information. The operator precuts the gypsum board 20 to have a larger board surface area than the board surface area of the heat insulating material 10 described later.
[0018] In step 102 (S102), an operator, for example, at a processing factory, cuts (precuts) the heat insulating material 10 into a size (dimension) and shape corresponding to the housing design information based on the housing design information. The operator precuts the heat insulating material 10 to have a smaller board surface area than the board surface area of the gypsum board 20.
[0019] In step 104 (S104), an operator adheres the heat insulating material 10 precut based on the housing design information to a position based on the housing design information on the gypsum board 20 precut based on the housing design information. Specifically, the operator applies an adhesive 50 between the heat insulating material 10 and the gypsum board 20, and adheres the heat insulating material 10 and the gypsum board 20 (hot melt bonding) with the heat insulating material 10 positioned inside from the outer edge of the gypsum board 20.
[0020] In step 106 (S106), the worker adheres the viscoelastic member 30 to the surface of the gypsum board 20, to which the insulation material 10 has not yet been attached, at the processing plant, in a position based on the house design information. Specifically, the worker adheres the viscoelastic member 30 to the surface of the gypsum board 20 at the position where the gypsum board 20 will come into contact with the framework, such as columns or studs, while the gypsum board 20 is installed on the house frame. The worker adheres the viscoelastic member 30 so as to surround the insulation material 10. In this way, workers can reduce the amount of work at the construction site by manufacturing the building panels 1 at the processing plant. In this method, the case in which the gypsum board 20 is pre-cut before the insulation material 10 is pre-cut is described, but this is not the only way; the insulation material 10 may be pre-cut before the gypsum board 20, and the order of work can be changed.
[0021] As described above, the building panel 1 in this embodiment simplifies work at the construction site by manufacturing the building panel 1 at a processing plant. This reduces the workload on workers and shortens working time. Furthermore, it allows for consistent quality of the building panel 1. Furthermore, by using gypsum board as the facing material, the building panel 1 is less prone to cracking than volcanic glass composite boards and has higher fire resistance than wood-based structural MDF boards, thus improving these performance characteristics. Although embodiments of the present invention have been described above, the invention is not limited thereto, and various modifications and additions are possible without departing from the spirit of the invention.
