Field boards made of wood, etc. are nailed to the rafters, and asphalt roofing, plastic sheets, felt, and waterproof sheets made of composites of these are placed on top of the roofing boards, and roofing materials such as metal plates, slate boards, tiles, etc. are then covered. It was raised. However, a roof with such a structure has a drawback that its insulation effect is very small, and due to temperature differences, condensation tends to occur on the back side of the roofing material and the back side of the waterproof sheet, and that it is easy to corrode the roofing boards and the like. Furthermore, because it is a combination of solid members and the board thickness is thin, it has poor sound insulation and sound absorption properties, and has the disadvantage that rain noise and noise propagate indoors. Furthermore, roofing materials made of colored iron plates, for example, are susceptible to plastic deformation and distortion due to external forces, and since no backing material is applied to counteract this, the roofing surface becomes uneven and the appearance is severely damaged.

げる。 An embodiment of the roofing method according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view for explaining the method according to the present invention, in which 1 is a rafter and 2 is a composite board, which is a member in which a sheet 3, a synthetic resin foam 4, and a fiberboard 5 are integrally formed. That is, the composite board 2 is a lamination of a sheet 3, a synthetic resin foam 4, and a fiberboard 5.
When forming a synthetic resin foam, it is integrated and bonded all at once using an in-situ foaming method. To explain further, sheet 3 includes kraft paper, asbestos paper, felt, asphalt felt, synthetic resin sheet,
These include one or more types of metal foil (aluminum, iron), a sheet laminated with a net-like material, nonwoven fabric, lath wire mesh, etc., or a sheet that has been subjected to waterproof treatment. Normal roofing material is approximately 300Kg/
It needs strength to withstand m 2 (laminated snow load), and since the bending strength of the composite board 2 is directly influenced by the tensile strength of the sheet 3, a material of about 3 kg to 130 kg is used. Furthermore, when metal foil, such as aluminum foil, is used, it also has a heat radiation effect and has the function of blocking heat conduction to the outside. Furthermore, the synthetic resin foam (hereinafter simply referred to as foam) 4 is formed by mixing a blowing agent with an isocyanate-based synthetic resin raw material and forming it on-site by foaming, for example, polyisocyanurate foam, polyurethane foam, etc. foam, polyurea foam, phenol foam, etc. This foam 4 functions as a heat insulating material, a core material, and a binder. In particular, it is preferable that the foam 4 is impregnated into the communicating voids of about 1/5 to 2/3 of the thickness of the fiberboard 5 and hardened, for example, in the portion where it is bonded to the fiberboard 5. This consists of fiberboard 5 and foam 4
This means that the adhesion between the foam 4 and the fiberboard 5 becomes strong due to the reaction of the foam 4, the self-adhesive properties during foaming, and the anchoring effect of the foam 4 to the fiberboard 5. The strength of the composite board 2 is improved, and it can be used in place of the conventional roofing board. Furthermore, the density of the foam 4 is approximately
10-50Kg/m 3rd place, compressive strength is about 0.5Kg/cm2 or more,
Thermal conductivity is 0.025 kcal/m・h・℃ or more, the plate thickness is about 5 mm or more, and the cell is closed or open cell. Moreover, it is a foam that can be elastically deformed up to 10% or more to about 30% of the board thickness. In other words, the foam 4 of the composite board 2 functions as a cushioning material and a cushioning material even under the influence of snow accumulation, external force, etc., so that the elastic deformation of the roofing material is maintained, and the portion that is in contact with the rafters 1 This is to prevent the foam 4 from being plastically deformed. In addition, the fiberboard 5 has humidity control properties, heat insulation properties,
It functions as sound absorption, sound insulation, reinforcement of bending strength and compressive strength, reinforcement of elastic deformation, and as a surface for placing roofing materials, and the plate thickness is about 7 mm or more, for example, 9 mm,
12mm density less than 400Kg/ m3 , bending strength 30Kg/m3
cm2 or larger. Specifically, they include sheathing board, rock wool, glass wool cellulose fiber, etc. Furthermore, the size of this fiberboard 5 is generally 900 x 1800 mm. Composite board 2 with such a structure connects foam to rafter 1 through sheet 3.
and is fixed to the rafter 1 via nails 6.
This is to absorb the unevenness caused by the rafters 1 by elastic deformation of the foam 4 and to make the surface of the fiberboard 5 flat. Further, it is preferable that the composite board 2 is laid so that its longitudinal direction is orthogonal to the rafter 1, and the end edge 2a is located above the rafter 1. This means that most of the composite boards 2 are supported by the rafters 1, and
The reinforcing material 7, which will be described later, is attached to the edge 2 of the adjacent composite plate 2.
This is to facilitate the installation by the rafter 1 when installing the nail 6 at the connection position with a'. The reinforcing material 7 covers and connects the connecting position of the composite plate 2 at least in the rafter direction, and by covering and connecting the composite plate 2, it can resist weak points of the composite plate 2, especially compression, and From the rafter 1 to the edge 2a,
The main function is to prevent 2a' from falling off, and for example, a thin metal plate, a synthetic resin plate, etc. are used. The width l of this reinforcing material 7 is at least 5 to 20
It is large enough to cover an area of mm. In addition, in the corner part, the reinforcing material 7 covers only the edge of one sheet because there is no adjacent composite board 2. 8
is a tarpaulin sheet, such as asphalt felt,
Layer and lay waterproof sheets, etc., in order from the eaves toward the ridge. In particular, an overlapping portion 8a is provided, on which there is a waterproof sheet 8 which is subsequently laminated. Next, when the installation of the waterproof sheet 8 is completed, a groove plate 9 is used as the roofing material, the groove plate 9 is passed through and supported via a hanger 10, a cap 11 is placed on top of the groove plate 9, and the crimping process is carried out in sequence. The roof is thatched by doing this.

Also, the nails 6 on the composite board 2 other than the joints
For example, a nail head embedding prevention metal fitting as shown in FIG. 3 may be used to fix the nail head. Further, a composite plate 2 in which a sheet 3 is made to protrude outward from at least one side of a foam 4 can also be used.

る。 As described above, according to the roofing method of the present invention, the roof is provided with heat insulation properties by the composite plates, and the composite plates are laid one after another, reinforcing material is brought into contact with the joints, and the entire roof is improved. It is easy to work because it is simply fixed with nails, and it does not require roofing boards, making it easy to construct. In addition, waterproofness is sufficiently ensured by laminating waterproof sheets and is further reinforced by roofing materials. Furthermore, since the composite board is laid so that the foam is in contact with the rafters through the sheet surface, unevenness of the rafters can be eliminated. Moreover, since the contact position of the composite board is covered with a reinforcing material and connected at least in the direction of the rafters, the compressive strength of the connection part and the resistance to pulling out the nail are strengthened, and the composite board does not fall off from the rafter. Moreover, in the roofing method according to the present invention, most of the work can be done on a flat surface on the composite board,
Improves safety and work efficiency. It has the following effects and characteristics.
