Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a flash panel in which a core material is arranged.

[0002]

2. Description of the Related Art In a conventional flash panel, a core material cut into a size corresponding to the internal size of the panel frame is loaded into a rectangular panel frame, and both sides of the panel frame loaded with this core material are loaded. It was formed by attaching an outer plate.

[0003]

In the conventional example having the above-mentioned structure, since the core material is simply put in the inside of the panel frame, the core material has a size corresponding to the inside dimension of the panel frame. It is necessary to cut the core material, and it is necessary to cut the core material to an accurate dimension.If the cutting accuracy is poor, the core material will shift inside the panel frame and it will not be possible to obtain stable quality. In addition, when forming flash panels with different dimensions, it is necessary to prepare core materials with different dimensions in addition to the frame material and face plate, and there is a problem that it is not possible to easily deal with size changes. . Further, when the panel frame is made of wood, not only the appearance is good, but warpage is likely to occur, and the strength is not sufficient.

The present invention has been made in view of the above-mentioned problems of the prior art, and its object is to prevent the core material from shifting and to easily apply it to flash panels of different sizes. You can change the dimensions and load the core material,
Another object of the present invention is to provide a method of manufacturing a flash panel which is hard to warp and has high strength even though the outer peripheral portion is made of wood and has a good appearance.

In this embodiment, two iron cores 1 are connected by an expandable core material 2 and a wooden horizontal frame 5a is installed between the upper ends and lower ends of both iron cores 1 to connect the horizontal frame 5a to the iron core 1. To form a frame body 3a as shown in FIG. 8 (a). In this case, the elastic core material 2 is stretched to a length corresponding to the length of the horizontal frame 5a. Therefore, by changing the length of the horizontal frame 5a, it is possible to configure the frame bodies 3a having different sizes. Here, the middle horizontal rail 7 is inserted in the middle horizontal rail placement gap 6.
Is fitted. As shown in FIG. 8B, a wooden vertical frame 5b is fixed to the outer surface of the iron core 1 located on both sides of the frame body 3a having such a structure. In this case, the horizontal frame 5a
The iron core 1 is fixed to the horizontal frame 5a or the middle horizontal bar 7 and the frame member 5 by fixing the middle horizontal bar 7 and the vertical frame 5b with a fixing tool 11 such as a tacker nail. Become. Of course, the iron core 1 and the vertical frame 5b may be directly fixed to each other. Also, iron core 1
The middle cross rail 7 may be directly fixed to each other. Then, the outer panel 4 is attached to both front and back surfaces of the frame body 3a having the vertical frames 5b fixed to both sides to form a flash panel as shown in FIG. 7, and such a flash panel is, for example, a door. It will be. In this embodiment, it is possible to deal with flash panels of various sizes by expanding and contracting the core material 2 only by changing the lengths of the upper and lower horizontal frames 5a and the middle horizontal rails 7.

FIG. 9 and FIG. 10 show still another embodiment of the present invention. In this embodiment, the basic manufacturing method is the same as that of the embodiment shown in FIGS.
In the embodiment shown in FIG. 8, step portions 15 are further provided at both ends of the wooden horizontal frame 5a, and the iron core 1 is positioned on the step portions 15 so that the upper and lower end surfaces of the iron core 1 are connected to the ends of the horizontal frame 5a. It is covered with a section. When the wooden vertical frames 5b are fixed to the outer surfaces of the iron cores 1 on both sides in this manner, the iron cores 1 are not exposed at the outer peripheral portion as shown in FIG. 10, and the wooden vertical frames 5b and the wooden horizontal frames are provided at the outer peripheral portion. The frame 5a is exposed and the appearance is improved.

FIG. 11 shows still another embodiment of the present invention. In this embodiment, the iron core 1 is provided with a biting protrusion 8 for fixing the middle cross rail. That is, in fixing the middle horizontal rail 7 to the iron core 1 in each of the above-described embodiments, the core material is set so as to separate the two iron cores 1 from the middle horizontal rail 7 by a distance as shown by an arrow a in FIG. 2 is expanded further, and then the iron core 1 is moved as shown by an arrow B to press the iron core 1 against the end face of the middle horizontal rail 7, thereby causing the biting protrusion 8 to bite into the middle horizontal rail 7. 7 and the iron core 1 are fixed to each other. In this case, the biting protrusion 8 can be surely bited into the middle horizontal rail 7 by hitting the iron core 1 with a hammer or pressing the iron core 1 with a pressing device. In this way, by providing the iron core 1 with the biting projection 8 for fixing the middle horizontal rail, the middle horizontal rail 7 and the iron core 1 can be easily fixed.
