Abstract

(57) [Summary] [Purpose] Even if a reinforcing material is provided, it is possible to reduce the labor at the time of manufacturing. Don't increase costs. [Structure] The surface material 3 is attached to the upper surface and the lower surface of the frame body 4 to form the panel body 1. The reinforcing material 2 that abuts on the inner surfaces of both surface materials 3 attached to the upper and lower sides of the panel body 1 is formed by injecting and foaming the foamed resin 5. Due to the self-adhesiveness of the foamed resin 5, the reinforcing material 2 can be fixed to the inner surface of the surface material 3 without an adhesive. Further, since the reinforcing material 2 is in contact with both inner surfaces of the surface material 3, the surface material 3 can be reinforced with the reinforcing material 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a building panel used for a floor or wall of a house.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, building panels formed by attaching surface materials 3 to the upper and lower sides of a frame body 4 are often used to form floors and walls of houses, especially outer walls and partition walls. In such a construction panel, the surface material 3 is made as thin as possible in order to reduce the weight, but on the other hand, there is a problem that the strength of the surface material 3 is lowered.

Therefore, as shown in FIGS. 3 (a) and 3 (b), a reinforcement body 10 formed of a stepped ball is arranged at the substantially central portion inside the panel body 1, and the upper and lower surfaces of the reinforcement body 10 are arranged. A building panel has been proposed in which the inner surface of the upper and lower surface materials 3 is bonded and fixed using an adhesive. With such a construction panel, even if the thickness of the surface material 3 is thin, the reinforcing material 10 can reinforce the surface material 3 and prevent the strength of the surface material 3 from decreasing. Is.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, the reinforcing body 10 has to be adhered and fixed to the surface material 3 with an adhesive, which increases the time and labor required for manufacturing the building panel. It also led to cost increase. The present invention has been made in view of the above points, and it is an object of the present invention to provide a building panel that does not increase the cost by reducing the labor at the time of manufacturing even if a reinforcing material is provided. .

[0005]

[Means for Solving the Problems]

 In the building panel according to the present invention, the surface material 3 is attached to the upper and lower surfaces of the frame body 4 to form the panel body 1, and the panel body 1 is reinforced by abutting the inner surfaces of both surface materials 3 attached above and below the panel body 1. The material 2 is formed by injecting and foaming a foamed resin 5.

[0006]

[Action]

 Since the reinforcing material 2 that comes into contact with the inner surfaces of both the surface materials 3 attached to the upper and lower sides of the panel body 1 is formed by injecting and foaming the foam resin 5, the self-adhesiveness of the foam resin 5 causes the surface of the reinforcement material 2 without an adhesive. It can be fixed to the inner surface of the material 3. Further, since the reinforcing material 2 is in contact with both inner surfaces of the surface material 3, the surface material 3 can be reinforced with the reinforcing material 2.

[0007]

【Example】

Hereinafter, the present invention will be described in detail with reference to embodiments. The reinforcing material 2 is formed by foaming the foamed resin 5 by heating or the like, and may be any as long as it is foamed to form the reinforcing material 2. For example, a phenol resin or urethane resin may be used as a foaming agent or It is possible to use the one prepared by blending a curing catalyst and the like. In this embodiment, a phenol resin is used as the resin. As the foaming agent, Freon R-11, R-113, methylene chloride and the like can be used alone or in combination. As the curing catalyst, sulfuric acid, hydrochloric acid, phosphoric acid or the like can be used as the inorganic acid, and benzene sulfonic acid, toluene sulfonic acid, phenol sulfonic acid or the like can be used as the organic acid. In addition, a foam stabilizer, a flame retardant and the like can be added if necessary. The mixing ratio of the phenol resin, the foaming agent, and the curing catalyst is determined in consideration of the reactivity and the density of the reinforcing material 2 formed after foaming, and in this embodiment, foaming having a density of 20 kg / m ³ is performed. Resin 5 is used.

The surface material 3 has been conventionally used for floor panels and wall panels, and examples thereof include gypsum board and particle board. The thickness is appropriately determined depending on the construction conditions, but when it is used for a wall, it is preferably about 6 to 9 mm. The frame body 4 is formed by assembling wood or the like into a rectangular frame shape. Next, the manufacturing process of the building panel of this embodiment will be described. First, the surface material 3 is attached to the lower surface of the frame body 4 to form the panel substrate 6. Next, as shown in FIG. 2A, the foamed resin 5 is injected from above the panel substrate 6 by spraying or the like to the substantially central portion of the inner surface of the surface material 3 provided on the panel substrate 6. Prior to the injection and injection of the foamed resin 5, the panel substrate 6 may be preheated by heating with a device or the like capable of heating the medium wavelength infrared rays. Thereafter, as shown in FIG. 2B, the foamed resin 5 is foamed to form the reinforcing material 2. This foaming may be carried out by heating the foamed resin 5, and as the heating device, a ceramic panel heater or the like capable of performing far-infrared heating is used. Next, as shown in FIGS. 2C and 2D, the panel substrate 6 is passed under the press roll 7 so that the upper portion of the reinforcing material 2 protruding above the upper surface of the frame 4 is pressed by the press roll 7. To prevent the upper surface of the reinforcing member 2 from projecting above the upper surface of the frame body 4. Finally, by attaching the surface material 3 to the upper surface of the frame body 4 of the panel substrate 6 and bringing the inner surface of the surface material 3 into contact with the upper surface of the reinforcing material 2, the reinforcing material is provided inside the panel body 1 as shown in FIG. The building panel provided with 2 is formed.

In the building panel thus formed, since the reinforcing material 2 abuts on the inner surface of the surface material 3 provided on the upper and lower sides of the panel body 1, the surface material 3 can be partially reinforced, and the thin structure is thin. It is possible to prevent the strength from decreasing even if the surface material 3 is used. Further, since the reinforcing material 2 is formed by injecting the foamed resin 5 on the inner surface of the lower surface material 3 and then foaming it, the reinforcing material 2 is formed by the self-adhesiveness of the foamed resin 5 and thus the inner surface of the lower surface material 3. It is fixed on the top and does not require an adhesive for attaching the reinforcing material 2.

[0010]

[Effect of device]

 As described above, according to the present invention, since the reinforcing material that comes into contact with the inner surfaces of both the surface materials mounted on the upper and lower sides of the panel body is formed by the injection foaming of the foamed resin, the reinforcement material is bonded by the self-adhesiveness of the foamed resin. Can be adhered to the inner surface of the surface material without the use of a reinforcing material, and since the reinforcing material is in contact with both inner surfaces of the surface material, the surface material can be reinforced with a reinforcing material, and even if a reinforcing material is provided, it can be manufactured. It saves time and effort and does not increase costs.
