Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ceiling finishing material which prevents hanging in the longitudinal direction.

[Conventional technology and its problems]

For plywood and other wood finishing materials used as ceiling finishing materials in Japanese-style rooms, generally thin board materials are used. For this reason, a long ceiling finishing material cannot be supported alone, and in consideration of workability, a reinforcing material is provided in the ceiling finishing material.
An example thereof is shown in FIG.

In this example, reinforcing materials 2 and 3 are arranged and fixed on the back surface of the ceiling finishing material body 1 at the respective ends in the longitudinal direction and the width direction thereof, and the reinforcing material is reinforced at predetermined intervals in the longitudinal direction of the ceiling finishing material body. The middle reinforcing member 4 is arranged so as to be substantially parallel to the member 3, and the end faces of the reinforcing member 3 and the middle reinforcing member 4 are brought into contact with the inner surface of the reinforcing member arranged in the longitudinal direction and fixed by the staple 5. There is.

In this case, since the middle reinforcing materials 4 are arranged in parallel, when manufacturing the ceiling finishing material, the middle reinforcing materials 4 are densely arranged without gaps, and the ceiling finishing material main body is formed with a considerable number of steps. If the ceiling reinforcing material 4 and the middle reinforcing material 4 are not fixed, the ceiling finishing material body hangs down, that is, the central portion of the ceiling finishing material body hangs down, which not only spoils the aesthetics of the ceiling surface but also causes a large number of staples. It takes time to hit.

An object of the present invention is to provide a ceiling finishing material capable of preventing hanging of the ceiling finishing material even when the number of staples used is reduced when manufacturing the ceiling finishing material.

[Means for solving problems]

In order to achieve the above object, the ceiling finishing material of the present invention is integrally provided with reinforcing members which are parallel to each other along both longitudinal and widthwise ends on the back surface of the main body of the ceiling finishing material and the reinforcing material provided in the longitudinal direction. The gist is that a zigzag middle reinforcing material is provided between the materials.

[Action]

The middle stiffener that extends in a zigzag pattern between the reinforcements provided on the back side of the ceiling finisher body makes the longitudinal direction of the ceiling finisher body asymmetrical in the width direction of the ceiling finisher body. It is supported in the form of a truss, which increases the restraining force of the ceiling finishing material body and prevents the ceiling finishing material body from hanging in the longitudinal direction.

〔Example〕

Hereinafter, the ceiling finishing material of the present invention will be described based on the illustrated embodiment.

In the figure, reference numeral 1 denotes a ceiling finishing material body having a required size and using a base plate or other desired material.

The reinforcing material 2 is arranged along the longitudinal end portion of the ceiling finishing material body 1, has a length over the entire length of the ceiling finishing material body 1 in the longitudinal direction, and is adhered or by another method. It is integrally joined with 1. The reinforcing materials 2 and 2 are arranged in parallel.

The reinforcing material 3 is arranged along the widthwise end portion of the ceiling finishing material body 1 and between the end portions of the reinforcing material 2, and is integrally bonded to the ceiling finishing material body 1 by adhesion or another method like the reinforcing material 2. To be joined. The end surface of the reinforcing material 3 is in contact with the inner surface of the end portion of the reinforcing material 2, and the reinforcing materials 2 and 3 are connected and fixed by a staple 5.

In this way, the frame-shaped reinforcing members 2 and 3 are joined to the ceiling finishing material body 1 and fixed integrally.

The middle reinforcing material 4 is arranged so as to bridge between the two reinforcing materials 2 arranged along the longitudinal end surface of the ceiling finishing material main body 1. It is arranged in an oblique direction so as to abut at a predetermined angle. Then, the zigzag shape is formed by alternately arranging the slanting directions of the strips one by one. The end surface of the middle reinforcing member 4 is brought into contact with the inner surface of the reinforcing member 2, and the staple 5 is connected and fixed.

[Effect of device]

According to the present invention, reinforcing members which are parallel to each other along both longitudinal and widthwise ends are integrally provided on the back surface of the main body of the ceiling finishing material, and zigzag-shaped intermediate reinforcing members are provided between the reinforcing members provided in the longitudinal direction. Since it is provided by straddling, the middle reinforcing material provided in a zigzag shape supports one part in the longitudinal direction of the ceiling finishing material body in a truss shape asymmetrically in the width direction of the ceiling finishing material body. It is possible to improve the accuracy of the ceiling finishing surface by increasing the restraining force of the finishing material body to prevent the hanging of the ceiling finishing material body in the longitudinal direction. Further, as compared with the conventional ceiling finishing material in which the middle reinforcing material is provided in parallel, it is possible to prevent the hanging of the ceiling finishing material body in the longitudinal direction even if the number of the middle reinforcing materials to be arranged is reduced. Therefore, it is possible to reduce the number of staples required to fix the main body of the ceiling finishing material and the middle reinforcing material, and it is possible to improve the work efficiency at the time of manufacturing the ceiling finishing material.
