Description

[Detailed explanation of the invention] The switchboard is called a mosaic panel, and the necessary instruments D are arranged and stored in the squares A at the desired positions of the panel frame, which is integrally configured in a vertical and horizontal grid pattern, and other squares are arranged and stored. It is known that tiles B (plastic plates or metal plates) are attached to the road surface to form a panel surface.

Furthermore, in constructing this panel frame, a large number of metal hollow blocks C, C, which are called cut-free type and are formed into a rectangular tube shape, are mechanically connected to form an arbitrarily shaped panel frame, as shown in Fig. 11. is being constructed.

To connect multiple hollow blocks, a bolt with a cross-shaped hook formed on the head and a washer also having a cross-shaped hook are used, and at the part where the corner parts of the four hollow blocks are butted, The adjacent hollow blocks can be integrally connected by engaging hooks formed on the bolt head and washer and tightening the nut.

However, at the periphery of the panel frame, only 2
Since the hollow blocks are continuous on both sides, two of the four hooks are free and cannot be connected.

In order to avoid this, it is conceivable to penetrate the wall surfaces of two adjacent hollow blocks in the right angle direction and fix them with another bolt E, as shown by the two-dot chain line in Fig. 1, but in this case, the peripheral part Inside the small hole, the bolt head and nut of bolt E protrude from the walls on the top and bottom or left and right sides of the small hole, and instruments D
It has the disadvantage that it gets in the way when you place and store it.

In view of these drawbacks, the present invention has been devised so that the hollow block can be connected to the fasteners by using hook bolts with hooks formed in the peripheral area of the panel frame in the same way as in other areas.

Hereinafter, the present invention will be explained based on the attached drawings, which are examples.

FIG. 1 shows an example of a cut-free mosaic panel, in which a large number of rectangular cylindrical hollow blocks 1 shown in FIG. 2 are connected.

As shown in FIG. 2, the hollow blocks 1 are provided with cutout surfaces 2 by recessing the ridgeline portions of the four corners, and when the hollow blocks 1 are arranged vertically and horizontally as shown in FIG. A void space a is formed in a portion surrounded by surfaces 2 and 2.

To connect a plurality of hollow blocks 1, 1, when arranging the hollow blocks 1, 1 as shown in Figs. 3 and 4, insert a hook bolt into the cavity a formed by butting the corners of the hollow blocks. Insert 4,
Hook bolts 3 formed on the head are respectively engaged with four adjacent hollow blocks on the back side of the hollow block 1, and a washer equipped with cross-shaped hook hooks 5, 5 is provided on the threaded portion of the hook bolt 4 projecting to the front side. 6, and engage the hooks 5, 5 on each of the four hollow blocks 1, 1, and then tighten the nut 7 from above to firmly connect the four adjacent hollow blocks to each other.

By performing the above operations continuously in all directions, a large grid-like panel frame of any shape can be constructed.

At the corner portions where the hollow blocks are connected, stepped portions 8 and 8' are formed so that the hook bolts 4 and nuts 7 do not protrude from the surface of the completed panel frame, and these portions are made narrow.

When connecting hollow blocks, see Figure 7.
As shown in FIG. 8, a hook bolt without a hook on the head may be used, and a washer 6' having a hook 5' may be interposed between the hollow block 1 and the head of the hook bolt.

By the way, since the hollow blocks 1, 1 are simply continuous in the vertical or horizontal direction at the top, bottom, right and left sides of the panel frame (Fig. 1), the four hook bolts 4 on the outer peripheral surface of the entire panel frame are Inside the hanging nail 2
The book becomes free and no strong connection can be made in that part.

Therefore, in the present invention, a patch plate 9 is brought into contact with the outer peripheral surface of a panel frame in which hollow blocks are arranged.
By forming a bulging portion 10 in the front, the four hooks of the hook bolt 4 and the washer 6 can be engaged in a well-balanced manner and can be firmly connected.

That is, as shown in FIG. 1, this contact plate 9 is provided with semicircular bulges 10 at regular intervals (the length of one side of the hollow block).
As shown in the figure, a hollow part a through which the hook bolt 4 passes is formed between the notch surface 2 of the other two hollow blocks 1 and the bulge part 10 of the backing plate 9, similar to the connecting part in the center part shown in FIG. Allow to form.

The patch plate 9 may be a long piece with bulges 10 provided at predetermined intervals;
As shown in Fig. 10, the total length is shorter than one side of the hollow block, and there is a
It may also be provided with bulges 10 at certain locations.

In the case of a long piece, for example, one side of the panel frame can be entirely covered with one backing plate. However, the places where it can be used are naturally limited.

On the other hand, if it is made as short as one hollow block, it can be arbitrarily placed in any part.

Note that the bulging portion of the backing plate 9 is the stepped portion 11, 11'.
are provided so that they have the same width as the corner portions of the hollow block 1.

In the panel frame formed in this way, the inside of each hollow block 1, 1 becomes one channel A, where the necessary instruments D are placed as appropriate, and the other channels are filled with tiles. B is inserted into the hole.

The bulging part of the backing plate 9 protrudes to the outer peripheral surface of the combined panel frame, and does not affect the holes in each hollow block. can be installed.

When trying to form a large conduit, for example, as shown in Fig. 1, a conduit four times the size of conduit A is used.
When forming A', it is sufficient to remove four hollow blocks in the part of the channel concerned.

In this case, the four sides of the conduit A' are brought into contact with the backing plates 9, 9 in the same way as in the case of the outer surface of the panel frame, and the hollow blocks 1, 1 are connected with the hook bolts 4 to form a large conduit A'. do.

The bulge 10 of the backing plate 9 will protrude from the inner surface of the large channel A' formed in this way, but since the channel A' is large, it will not cause much trouble in mounting instruments. do not have.

According to the cut-free type mosaic panel panel frame of the present invention, the hollow blocks at the periphery can be connected to the fasteners using hook bolts having hooks on all sides in the same way as the hollow blocks at the center, and, The hollow block in the center of the assembled peripheral hollow blocks does not create unnecessary protrusions on the walls of the upper and lower sides or the left and right sides of the hollow block, as in the case of bolting through the wall. Instruments can be installed under the same conditions as the block channel.
