It will be firmly fixed vertically.

Further, since the cylinder connecting rods 3 are provided at the four corners of the cylinders 1 and 2, they will not be an obstacle at all during evacuation.

(Example) Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is a plan view showing the floor-embedded evacuation equipment storage box repaired by the present method invention with the top cover removed, and FIG. 2 is a cross-sectional view of FIG. Figure 3 is the first
It is a sectional view of Rollo in the figure.

In the figure, A is the concrete slab that forms the floor, and F is the cylindrical frame of the existing floor-embedded evacuation equipment storage box that is to be repaired. Further, 1 is a repair lower cylinder forming the repair assembly type storage box of the present invention, 2 is a repair downstream cylinder, 3 is a cylinder connecting rod,
4 is an upper lid, 5 is a lower lid, 6 is a lower lid hanging rod, and 7 is a ladder hanging fitting.

The repair lower cylinder body 1 is formed in a size that can be inserted into the existing frame cylinder body F, and has a frame cylinder body F at its upper end.
A locking flange f5 having a cross-sectional shape that covers the upper end flange pa and engages with the slab concrete A is formed. Also,
A hanging fitting 7 of a ladder 7 is fixedly installed inside the upper cylinder 1.
Further, on the front side wall of the locking flange 1a of the upper cylinder 1, an upper lid support fitting 1b is fixedly provided to rotatably support one side of the upper lid 4.

The repair lower cylinder body 2 has dimensions that can be inserted into the existing frame cylinder F, and its inner dimension is slightly larger than the outer dimension of the upper cylinder body 2. That is, the lower end of the upper cylinder 1 and the upper end of the upper cylinder 2 are formed to be able to overlap. Furthermore, a locking flange 2a that engages with the concrete slab A is formed at the lower end of the upper cylinder 2, which covers the lower flange Fb of the existing frame cylinder F and engages with the concrete slab A.

Tongue-shaped connecting fittings 1c and 2c are protruded from the four inner corners of the upper cylindrical body 1 and the upper cylindrical body 2, and the connecting rod 3 is inserted into the holes drilled in the connecting fittings 1e and 2c. By at least tightening the nut 3a, both cylindrical bodies 1 and 2 are firmly fixed to the concrete slab A via the upper and lower flanges la and 2a, respectively.

In this embodiment, the total length of the upper cylinder 1 and the upper cylinder 2 is made larger than the thickness of the floor, so that the ends of each are overlapped with each other when the two are assembled. However, it is also possible to shorten the lengths of the upper cylinder 1 and the upper cylinder 2 so that their ends do not overlap.

The upper lid 4 is dimensioned to cover the flange edge 1a at one end of the upper cylinder 1, and includes a support metal fitting 4a fixed to the front inner wall thereof and an upper lid support metal fitting 1b on the side of the upper cylinder 1. By connecting via a support pin 8, it is rotatably attached to the upper cylinder l.

The lower lid 5 is formed in a size that can be inserted into the lower cylinder body 2 for repair, and is formed in a so-called "drop-off lid" structure.

At the same time, remove the folding ladder C stored inside. The upper cover and the lower cover E are usually detachably attached to the frame cylinder F by means of support pins, and can be easily removed by removing the support pins.

Next, insert the upper cylindrical body l into the frame cylindrical body F from above the slab, engage the upper end flange 1a onto the upper end flange Fa of the frame cylindrical body F, and also Insert the cylinder 2 into the frame cylinder F. Thereafter, both the cylinders 1 and 2 are connected and fixed to the slab A by inserting the cylinder connecting rod 3 into the holes of the upper and lower connecting fittings 1c and 2C and tightening the nut 3a.

Finally, attach the upper cover 4 and lower cover 5 to the support pin 8 and the support pin 9.
After attaching the upper end of the folding ladder C to the ladder hanging bracket 7, the lower cover 5 is lifted and supported by the lower cover hanging rod 6, and finally the upper cover is Close 4.

In addition, in the above-mentioned FIGS. 1 to 3, the upper cover 4 and the lower cover 5 are
We have described the repair of the floor-embedded evacuation equipment storage box B, which has a mechanism that opens the lower lid 4 and the upper lid 5 separately. The storage box B includes an upper lid 4 (or lower lid 5) equipped with the link mechanism and an upper cylinder 1 (equipped with a link support mechanism).
Alternatively, after attaching the balls and the lower lids 4 and 5, respectively, using the upper cylinder body 2), the links are connected and the links are supported.

(Effect between lights) In the present invention, when repairing the floor-embedded evacuation equipment storage box B of the existing evacuation equipment, only the upper and lower covers and E are removed, leaving the frame cylinder F. At the same time, the upper cylinder 1 and the upper cylinder 2 are inserted into this frame cylinder F from above and below, and both cylinders 1.2 are tightened via the cylinder connecting rod 3, and both cylinders are attached to the concrete slab A. The bodies 1 and 2 are fixed together, and then the upper cover 4 and the lower cover 5 are attached to the upper cylinder body 1 and the upper cylinder body 2 so as to be openable and closable.

As a result, when replacing the floor-embedded evacuation equipment storage box B, there is no need to scrape the concrete slab A at all, eliminating problems such as noise generation and repairing the concrete slab after scraping, as well as the cost of repair work. It is possible to significantly reduce the

In addition, in the storage box for repair, the upper cylinder 1 having the upper end flange 1a and the upper cylinder 2 having the upper end flange line 2a are inserted into the frame cylinder F, and the upper cylinder body 2 is inserted through the connecting rod 3. The structure is such that both are tightened and fixed.

As a result, by tightening both cylindrical bodies 1, 2 with the connecting rod 3, both cylindrical bodies 1.2 are firmly fixed to the concrete slab A via the upper end and upper end collar wires 1a, 2a, and The existing frame cylinder F can be completely hidden, and the internal dimensions of the frame cylinder F will not be significantly reduced.

As described above, the present invention has excellent practical effects.
