Description

[Detailed Description of the Invention] A conventional door made of metal plate consisting of an outer panel and an inner panel has a reinforcing frame member r arranged along its inner periphery, so that the door does not bite into the frame during an earthquake. The drawback is that it won't open.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the object of the present invention is to provide an electric field that allows the door to be deformed by the external force of the frame during an earthquake.

A feature of the present invention is that a hollow reinforcing frame member having a rectangular cross section is installed along the inner periphery of a metal plate door called an outer panel and an inner 11111 panel. After forming, insert a core tube into each cut part, fix one end of the core to one side of the cut part, and insert the other end of the core through the elongated hole provided on the other side of the cut part. A fixing screw is screwed into the end so that the door can be deformed by external force from the frame in the event of an earthquake.

Hereinafter, the illustrated embodiment of the present invention will be explained in detail. Fig. 1 is a front view of the outer panel in use with a part cut away, Fig. 2 is an enlarged cross-sectional plan view taken along line A-B in Fig. 1, and Fig. 3 is a front view of the reinforcing frame member. Figure 4 is the third
FIG. 5 is an enlarged longitudinal sectional view taken along the line C-I) in the figure, and FIG. 5 is a plan view of the main part.

In the figure, reference numeral 1 denotes a metal plate door consisting of an outer panel 2 and an inner panel 3, which is attached to a frame 4 with a hinge 5. Reference numeral 6 denotes a flange formed on the front peripheral edge of the door 1, which covers seven gaps between the door 1 and the frame 4. Reference numeral 8 denotes a hollow reinforcing frame member disposed along the inner periphery of the door 1, and has a rectangular cross-sectional shape. Cutting portions 9 are formed in the middle of each side of the hollow reinforcing frame member 8, and ten cores are inserted into each cutting portion 9. One end of the core is fixed to one side 11 of the cut part 9 by welding or the like (-. There are 13 long holes formed on the inner surface of the other side 12 of the cut part 9, and c14 is a long hole. This is a fixing screw that is screwed into the other end of the core 10 through the hole 13, and when an external force is applied to the hollow reinforcing member 8, the other end of the cut portion 9 (fill 12) is inserted into the other end of the core 10. 15.16
is a reinforcing plate attached inside the frame 4. Although the drawing shows a channel member with a U-shaped cross section as a hollow reinforcing member, it is of course possible to form it in one piece, and the drawing also shows a door with a flange. The hollow reinforcing frame member described above may also be attached to a door that does not have a flange.

One door of the present invention configured as shown in Figure 1/'J
) As shown in FIG. 2, if the hinge 5 is attached to the frame 4, the door 1 can be used in the same way as a normal door unless a strong gravitational force is applied to the door 1. When an external force is applied to the door 1 from the frame 4 during an earthquake, the external force is transmitted to the hollow reinforcing frame member 8. If the magnitude of the external force is larger than the fixing force by the fixing screws 141/C, the hollow reinforcing frame member 8 will deform along the core 1°, so the door 1 will be forced into the frame 4.
It can be easily deformed without cutting into the material. Since the reinforcing plates 15 and 16 are attached to the frame 4, the frame 4 does not deform even though the door 1 deforms.

As can be easily understood from the above explanation, in the door of the present invention, an external force acts on the door rather than the frame during an earthquake.

Then, since it is easily deformed, the door will not bite into the frame and become unable to open, and the drawbacks of conventional doors, as described in L7 at the beginning, can be fully overcome.
