It has a stacked configuration.

[0006] The construction method of the conventional building panel constructed as described above will be described below. In the case of a building panel for a wall, the panel is fixed to the base frame with a nail or the like or an adhesive, and then the finishing material such as a waterproof sheet or a surface material is doubled and tripled so that wrinkles and the like do not get bent. It was fixed by applying adhesive or the like while bonding. In the case of building panels for roof bases and outer wall materials, tap screws or the like at the time of construction, glue dango etc. are arranged at equal intervals and without leakage, and then the panel is fixed on it I was When tightening with a tap screw at the time of construction, the accident that the surface material was crushed by the tightening of the screw was constantly required, and the work required skill. After the construction, a waterproof finish such as a waterproof paint or a waterproof sheet was further performed.

[0007]

However, in the above-mentioned conventional construction, when a building panel is used as a heat insulating wall material or the like, kraft paper and a wirelass are separately provided on one or both sides of the building panel, and then mortar. There is a problem that workability at the time of construction, such as application or application of an adhesive, is poor, and a great deal of labor is required. If the surface is a hygroscopic board such as gypsum board or concrete panel, attach a waterproof sheet such as asphalt roofing,
There has been a problem that the waterproofing work is required by applying a waterproof coating film such as an asphalt primer, the work is complicated, and the construction period is extended over many branches.

[0008] The present invention solves the above-mentioned conventional problems, and does not require the work of arranging wires and the like at the time of construction. An object of the present invention is to provide a building panel which can be remarkably shortened and can save labor, is excellent in high quality and high productivity in factory production, is low in cost, and is suitable for mass production.

[0009]

According to the present invention, there is provided a building panel comprising a nonwoven fabric made of an organic fiber material or a needle-punched sheet or mat made of an inorganic fiber material. And self-adhesive waterproofing mainly composed of straight or blown asphalt , rubberized asphalt , vulcanized or non-vulcanized rubber of polyolefin rubber or synthetic resin of polyvinyl chloride. And a plate material layer formed of any one of a wood wool cement board , a calcium silicate board , a cement board , and a gypsum board. The architectural board according to claim 2 of the present invention is a nonwoven fabric made of an organic fiber material or a base fabric layer made of a needle punched sheet or mat made of an inorganic fiber material, and a straight or blown asphalt or rubberized material. A self-adhesive waterproof layer mainly composed of one of a vulcanized or non-vulcanized rubber of asphalt or polyolefin rubber or a synthetic resin of polyvinyl chloride , and plywood , veneer board , wood board , wood wool cement board , A calcium silicate plate , a cement plate , or a gypsum board, and a foam layer disposed on the lower surface of the plate layer.

Here, the non-woven fabric is a sheet-like material obtained by arranging fibers in a thin cotton or mat shape by an appropriate method and bonding the fibers to each other by an adhesive or the fusion force of the fibers themselves. Examples of the material of the nonwoven fabric include synthetic resins such as polyester, polyamide, polyacrylonitrile, polyvinyl chloride, and polyolefin, and natural fibers such as plants. The needle punch sheet refers to a sheet formed by pressing a needle against a fiber mass to lock the fibers and thereby form a sheet. The mat refers to a needle punch sheet having a large thickness. Examples of the material of the needle punch sheet and the mat include glass fiber and mineral fiber.

[0011] The waterproof layer is made of straight or blown asphalt or rubberized asphalt having tackiness at normal temperature,
Alternatively, it is made of a vulcanized or non-vulcanized rubber of polyolefin rubber such as polychloroprene rubber or butyl rubber, or a synthetic resin such as polyvinyl chloride. As the waterproof layer, in addition to the adhesiveness, the one that impregnates the surface of the base fabric layer or the plate material layer at room temperature and has an anchor effect has a strong adhesive strength and is preferable. The most suitable one is selected and used according to the purpose such as floor, wall, roof and the like.

Examples of the board material layer include a wood wool cement board, a calcium silicate board, a cement board, and a gypsum board.
The plate material layer preferably has at least one porous surface and can be impregnated with a waterproof layer. When a foam layer is further provided on the other surface of the plate material layer, it is preferable that the laminate surface with the foam layer also has a porous surface. In addition, a waterproof layer and a base fabric layer may be formed on both sides of the plate material layer as well as on one side. It is convenient when mortar coating etc. is performed on both sides as a wall material. The plate material layer may be composed of one or more laminates. This is because the required properties differ depending on the application, and therefore, mechanical strength and the like corresponding to each application are provided.

As the foamed layer, a foamed board made of synthetic resin such as urethane foam, polyolefin foam, polystyrene foam, or a foamed concrete board is used. If a foam board having self-adhesive properties, such as rigid urethane foam, can be used to manufacture a building panel by integral molding, the step of laminating the foam board and the plate material layer can be omitted, and the number of production steps can be reduced, which is preferable. When the foam layer is provided, the thickness of the foam layer may be increased without using the foam plate in the plate material layer. The lamination of the foam layer and the plate material layer may be self-adhesive when an isocyanate-based one is used for the foam layer, or may be adhered with an adhesive or the like like other foam layers. By providing a foam layer, it can be used not only as a general building but also as a wall material for heat storage warehouses such as refrigeration, ships, vehicles, breweries and drying cabinets, and as a material for agricultural facilities such as chicken raising, pig raising, silos, etc. Can be.

In the manufacture of a building panel, a waterproof layer is formed on one or both sides of a board material layer, and then a base fabric layer is laminated or
Alternatively, the base fabric layer and the waterproof layer may be laminated in advance and then laminated on the plate material layer. After lamination,
Curing is preferable because the anchor portion is firmly formed.

[0015]

According to this structure, since the base fabric layer is firmly held by the waterproof layer, mortar coating can be performed directly on the base fabric layer, and mortar or the like enters between the fibers of the base fabric layer. Since the effect as an anchor material is exhibited, a strong mortar wall can be formed. In addition, since the waterproof layer is directly adhered or impregnated to the board material layer, if it is used as a roofing material, the roof foundation can be constructed in one process without installing a waterproof sheet etc. Floors and pillars under construction can be protected from rainwater without the need for construction of roof fins and the like. Further, since the foam layer is formed integrally, the soundproofing and heat insulating effects can be significantly improved, and the energy saving can be strongly promoted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. 1 is a side view of a main part of a building panel according to a first embodiment of the present invention, and FIG. 3 is an enlarged view of a main part of part A in FIG. Reference numeral 5 denotes a base fabric layer made of a nonwoven fabric such as polyester, 6 denotes a waterproof layer made of rubberized asphalt or the like, and 7 denotes a plate material layer made of a concrete panel or the like. In FIG. 3, reference numeral 8 denotes the base fabric layer 5.
The base material layer anchor portion 9 has a lower portion embedded and fixed in the waterproof layer 6, and 9 is a plate material in which a part of the waterproof layer 6 is impregnated on the upper surface of the plate material layer 7 and plays a role of an anchor material and is firmly fixed. It is a layer anchor part.

The method of using the thus constructed construction panel of this embodiment will be described below. When using as a floor, wall material or field board, use a sheet material layer on
7 is arranged and driven and fixed with nails or the like from the base fabric layer 5 side. Since the waterproof layer 6 is made of rubber-like asphalt or the like, the waterproof layer 6 is sticky and entangles around the nail, and due to its elasticity, the waterproof layer 6 closely adheres to the shape of the nail and moisture enters from around the nail portion. To prevent Even if the nail is accidentally hit and the nail is later pulled out, the nail hole covers the nail hole with the elasticity and self-adhesiveness of the waterproof layer 6, so that rainwater or the like does not enter the plate material layer 7. . Next, if mortar is applied to the surface of the base fabric layer 5, the fibers on the surface of the base fabric layer 5 are applied into the mortar layer.
It is possible to firmly fix the mortar layer without stretching a wire or the like.

(Embodiment 2) FIG. 2 is a side view of a main part of a building panel according to a second embodiment of the present invention. 5 is a base fabric layer, 6 is a waterproof layer, 7 is a plate material layer excluding a foam board, 8 is a base fabric layer anchor portion, and 9 is a plate material layer anchor portion, which are the same as those in the first embodiment. The same numbers are assigned and the description is omitted. Reference numeral 10 denotes a foam layer made of a rigid polyurethane foam or the like. Since the foamed layer 10 is made of a rigid polyurethane foam, the foamed layer 10 is integrally foamed on a laminated board composed of the base fabric layer 5 to the board material layer 7 and the rigid polyurethane foam is laminated in one step.
Note that the foamed layer may be formed by laminating with an adhesive or the like without integrally foaming. Further, the waterproof layer 6 and the base fabric layer 5 may be further provided on the surface of the foam layer 10. This is because it is convenient when used as a wall material.

The method of using the thus constructed construction panel of the second embodiment of the present invention will be described below. When used as an interior material, a floor, or a ceiling material of an inner wall, a building panel is fixed to a body edge, a joist, a ceiling edge, or the like in the same manner as in the first embodiment. Because of the foam layer, it functions as a heat insulating material and sound-absorbing material, effectively preventing dew condensation and achieving energy savings. it can. Conventionally, foaming boards were stuck with an adhesive one by one, or fitted between studs, etc., and heat insulation and soundproofing work required a great deal of labor and time. When the panel is used for construction of a wall or the like, a heat insulating and soundproof wall can be formed in one process, and the construction work can be remarkably reduced and the construction period can be shortened. If necessary, if a metal plate or a decorative plate is adhered and formed integrally on the surface of the foam layer, the surface finishing step becomes unnecessary, and the construction period can be further shortened.

[0020]

As described above, the present invention comprises a laminate of a base fabric layer, a waterproof layer, a plate material layer, and a foam layer provided as required, so that mortar coating or the like can be performed without using a wirelass or the like. It is possible to significantly improve workability during construction and to provide a low-cost house. Even when used with nails or the like, the adhesiveness and elasticity of the waterproof layer makes it adhere to the nail material, making it possible to completely waterproof, and the work of attaching conventional asphalt roofing, etc. Since it is unnecessary, the number of work steps during construction can be significantly reduced and the construction period can be significantly reduced. In addition, since the plate material layer is formed of a material having a low thermal conductivity and can be constructed with high airtightness, heat conduction in the room to the outside is small and the heat insulating effect is high. Accordingly, since the temperature of the inner surface is not reduced and dew condensation hardly occurs, deterioration over time due to moisture is small and durability can be improved. Since it has a foamed layer, it is excellent in heat insulation and soundproofing properties, and it is possible to carry out these constructions in one step, thereby making it possible to significantly reduce labor. Further, it is possible to realize an excellent architectural panel which can be easily manufactured in a factory and can be mass-produced at a low cost with high quality.
