Description

[Detailed explanation of the invention] The switchboard is called a mosaic panel, and the necessary instruments are arranged and stored within the grids at desired positions of the panel frame, which is structured in a vertical and horizontal grid pattern. tiles (plastic or metal plates)
It is known that the panel surface is constructed by attaching a

Furthermore, in configuring this panel frame, the first
As shown in the figure, a panel frame is formed by mechanically connecting a number of hollow metal blocks molded into rectangular tube shapes (cut-free mosaic panel).
There is.

The present invention relates to a cut-free mosaic panel in which a panel frame is constructed by connecting a large number of hollow blocks, and more specifically relates to the structure of the connecting portions between the hollow blocks.

Conventionally, in cut-free mosaic panels, it has been common to use special bolts and nuts to connect a large number of hollow blocks.

However, there was a drawback in that it was very time-consuming to assemble and disassemble a large panel frame using special bolts and nuts.
The present invention provides a panel frame which is easy to assemble and disassemble, and which is relatively sturdy when assembled.

Hereinafter, the panel frame for a mosaic panel of the present invention will be explained based on the attached drawings, which are examples.

As shown in Fig. 1, the cut-free type mosaic panel panel frame is made of a rectangular hollow block 1 made of aluminum die-casting or the like.
A large number of blocks 1 are connected vertically and horizontally to form a frame corresponding to the size of the panel surface, and the instruments A are appropriately arranged in the panel frame and accommodated in the channel B, which is the inside of the cylinder of the hollow block 1. , Tile C is installed on the other surface of the wall.

In the present invention, when connecting rectangular cylindrical hollow blocks to each other, the hollow blocks are arranged vertically and horizontally, and a connecting piece 2 having elasticity is fitted from both the front and back surfaces at the portion where the corner portions of each hollow block are abutted against each other. allows the hollow blocks to be interconnected.

Connecting piece 2 for connecting hollow blocks 1 and 1
In this example, holding pieces 2b, 2b are vertically disposed on both the left and right sides at both the front and rear ends of a thin top plate part 2a (width approximately twice as wide as the thickness of the hollow block), and the cross-sectional shape of the part is approximately U-shaped. The tip of the holding piece 2b is bent inward. [FIG. 2] The connecting piece 2 is made of a resilient material, for example, a plate spring.

On the other hand, on the inner surface of the rectangular cylindrical hollow block 1, as shown in FIG. 4, stepped portions 3, 3 of a constant width W are provided at a constant distance L from the corner. That is, the thickness t of the portion to be the stepped portion 3 is made thinner than the thickness T of the other portions.

Incidentally, in the range of dimensions L and L up to the provision of the step portions 3, 3, that is, the four corner portions of the hollow block, step portions 4, 4 are formed slightly downward from both the front and back surfaces. Also,
The stepped portion 3 is provided with a window hole 5 penetrating the wall surface or a stepped portion further down one step at a constant distance from both the front and back surfaces (cylindrical end surfaces).

The width of the point plate portion 2a of the connecting piece 2 is the same as that of the hollow block 1.
The length is approximately twice the thickness T of the wall of the hollow block, and the length thereof is approximately twice the dimension L from the corner of the hollow block to the stepped portion 3, that is, the dimension L of the stepped portion 4. Further, the width W of the stepped portion 3 provided on the inner peripheral surface of the hollow block is approximately the same as the width of the holding piece 2b of the connecting piece 2.
b can fit into the stepped portion 3.

In order to connect a plurality of hollow blocks using such a connecting piece 2, as shown in FIGS. 2 and 3, four adjacent hollow blocks 1a, 1b, 1
At the part where the corners of c and 1d are butted together, the connecting piece 2 is fitted vertically and horizontally from both the front and back end surfaces of the block, and the holding piece 2b of the connecting piece 2 holds a part of the adjacent block. .

In other words, referring to FIG. 2, a connecting piece 2 is fitted in the vertical direction on the front side, the upper holding piece holds the lower side walls of the hollow blocks 1a and 1b, and the lower holding piece holds the lower side walls of the hollow blocks 1c and 1d. Hold the upper part of each side wall. There is also a connecting piece 2 horizontally on the back side.
One holding piece holds the lower wall of the hollow block 1a and the upper wall of the hollow block 1d, and the lower holding piece holds the lower wall of the hollow block 1b and the upper wall of the hollow block 1c, respectively.
At this time, the holding pieces 2b of the connecting pieces 2 are all fitted into the stepped portions 3 of the hollow block.

Therefore, in this part, the four hollow blocks 1a to 1d are connected to each other by simply fitting the connecting pieces 2, 2 from the front and back sides of the blocks, and once connected, the holding pieces As a result of being fitted into the stepped portion 3, it exhibits a strong bonding force against forces in both the vertical and horizontal directions.

In addition, there are stepped portions 4 at the corners of both the front and back sides of the hollow block.
If provided, the top plate portion 2a of the connecting piece 2 will not protrude from the surface of the completed panel frame, and a window hole 5 will be provided in a part of the stepped portion 3 so that the tip of the holding piece 2b can be engaged. By doing so, the connecting piece can be prevented from accidentally falling off.

According to the panel frame for a mosaic panel of the present invention, a firmly connected panel frame can be obtained simply by fitting connecting pieces from both the front and back sides into the corners where a plurality of hollow blocks are butted against each other. Moreover, by fitting the holding pieces of the connecting pieces into the stepped portions 3 provided on the inner surface of the hollow block, it is possible to make the block more durable.
