DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building panel forming a floor or a wall and serving as a structural frame of a building, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, panel-type buildings constructed by combining a plurality of building panels such as floor panels and wall panels have been used. Such a building panel is formed into a rectangular flat plate, and forms a building frame of the building. A general building panel is composed of a frame formed by combining a plurality of frame members cut into dimensions according to the panel in a frame shape, and a face material attached to each of both sides of the frame. Have.

[0003]

As such a building panel, there are used a panel in which a plurality of panels are attached to a frame, and a panel in which one panel is attached to a frame. I have. Comparing these two, it is generally said that since there is no seam on the surface, the strength of the latter building panel to which one sheet of material is attached is higher. On the other hand, in the case where one piece of face material is attached to each side surface of the frame, when the face material is cut in accordance with the building panel, scraps are generated, and the scraps are often discarded. There is a problem that the effective utilization rate of raw materials is not good. Such a problem also occurs when one square member is provided on each side of the frame. In addition,
As a building panel, a plurality of long members formed in a short cylindrical shape by a finger joint are added in a longitudinal direction by finger joints, and these long members are arranged in a width direction and are adjacent to each other. In addition, there is known a material in which the side surfaces of other long materials are adhered to each other (see Japanese Utility Model Laid-Open No. 61-175412). In such a building panel, since it is necessary to form a cylindrical bar, the processing work is troublesome, and when forming the bar into a cylindrical shape, cutting waste is generated and waste of raw materials is large. There is a problem.

An object of the present invention is to provide a building panel and a method for manufacturing the same, which ensure sufficient strength, facilitate processing, and reduce waste of raw materials.

[0005]

A panel for a building according to the present invention will be described with reference to the drawings. A plurality of face materials 3 are arranged on the surface of a frame 2 in which a shaft assembly 4 is assembled in a frame shape. A plurality of face materials 3 that are adjacent to each other and are joined by a scarf joint 6. In the present invention, since the joining surfaces of the face materials 3 cut obliquely are joined to each other with an adhesive or the like, the joining area is enlarged as compared with the case where the joining surfaces are cut vertically, Even if the material 3 is thin, the face materials 3 are firmly joined to each other. For this reason, if the face material 3 integrated by the scarf joint 6 is attached to the surface of the frame body 2, the strength of the building panel 1 will be sufficiently secured, and the building panel 1 itself will not easily deform. Become. As a result, a face material obtained by joining plywood or the like having a small size with almost no scrap material at the time of cutting can be adopted as the face material 3 of the building panel 1, and generation of the scrap material is suppressed to a minimum.
Raw material waste can be reduced.

At this time, the frame member 4 is formed by adding a plurality of short prism members 5, and these prism members 5 are desirably joined by finger joints 7. . In this way, the frame member 4

End faces are joined together with an adhesive or the like and joined together, so that a framed material 4 having sufficient strength can be formed. In this regard, the generation of end pieces is suppressed to a minimum, and waste of raw materials is reduced. Can be reduced.

Further, it is desirable that the position of the finger joint 7 of the frame member 4 and the position of the scarf joint 6 of the face member 3 are shifted by at least one position. In this way, if the position of the finger joint 7 of the frame member 4 is shifted from the position of the scarf joint 6 of the face member 3, the external force applied to the building panel 1 causes the joint surface of the frame member 4 and the face member 3 to change. When the two are to be separated from each other, the firmly bonded frame member 4 and the face member 3 must be moved in the shearing direction, so that the joining surfaces of the face members 3 are less likely to be separated from each other. Compared to the case where the joining positions of the face materials 3 are set to the same position, a significantly greater strength is given to the building panel 1.

Further, the frame 2 has a pair of vertical bars 4A provided on both side edges, a pair of horizontal bars 4B connecting ends of the vertical bars 4A, and a pair of horizontal bars 4B. And an intermediate bar portion 4C for connecting the intermediate portions of the vertical bar to each other. On the surface of the frame 2, a face material 3 having a length corresponding to the length of the horizontal bar portion 4B is provided. It is desirable that a plurality of sheets be arranged along the portion 4A. In this way, when the face material 3 to be attached to the frame body 2 is replaced with a long and narrow X-shaped brace along the horizontal rail 4B,
Even if the angle of inclination of the brace becomes small and a strip-shaped face material disadvantageous in strength is adopted, the intermediate bar 4C is joined to the middle part of the face material 3 so that two The brace is formed, the inclination angle of the brace is greatly expanded, the deformation of the building panel 1 to which the face material 3 is attached is sufficiently suppressed, and the building panel 1 itself has sufficient rigidity. Become so.

In the method for manufacturing a building panel 1 according to the present invention, a plurality of face materials 3 are provided on a surface of a frame 2 in which a frame assembly material 4 is assembled in a frame shape.
In which the frame members 2 are formed by joining short prismatic members 5 with finger joints 7 to form a frame 2.
Is formed, a plurality of face materials 3 are attached to the surface of the frame 2, and adjacent face materials 3 are joined to each other by a scarf joint 6. In such a manufacturing method, when attaching the face material to the frame body 2 formed by the frame assembly material 4, the peripheral edge of the frame body 2 serves as a ruler for adjusting the position of the face material 3, and the frame body 2 of the face material 3 Can be easily adjusted. Thereby, the attaching work of the face material 3 can be easily performed, and the manufacturing operation can be easily performed.
