Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a floor box such as an outlet box for accommodating outlets arranged on a floor of a building.

[Conventional technology]

Word processors, facsimiles, office computers, copiers, etc.
With the increase in office equipment in offices, a large number of floor outlets for supplying power to these office equipment have been installed on the floor of the office. For this reason, floor boxes that store these floor outlets have been pre-arranged on concrete slabs when building a building, but outlets with different uses such as for low-power and high-power use. When the boxes for storing the boxes are configured as independent boxes, there is a problem that the work becomes complicated due to the large number of the boxes and the relationship with the bar arrangement work and the like at the site.

In order to eliminate such problems,
As seen in 62-132624 and 62-132625, the box bodies are connected to each other near the corners.
A device that improves workability on site has been proposed.

[Problems to be solved by the device]

As described above, there is known a floor box in which the box bodies are connected to each other in the vicinity of their corners in order to improve the workability of electric installation work at the site. However, in this conventional connection-type box, the corners of the box are connected by welding, and even if a connecting plate is used, it is a flat connecting plate, so the front and back of the box body between the corners.・ If a space cannot be obtained in the left-right direction, and if there is an intersection of reinforcements near the corner of the box body, there will be new problems such as having to cut the reinforcements on site each time. It turned out to occur.

Therefore, the present invention solves the above-mentioned disadvantages of the conventional floor box, and by using a crank type connecting plate, it is possible to obtain a front-rear and left-right space between the corner portions of the box body. A space is created between the bottom surface of the box body and the floor surface of the building by using the L-shaped grounding leg so that the bar arrangements can be inserted between the corners of the box body and the bottom surface of the box body. It is an object of the present invention to provide a concatenated floor box that dramatically improves the workability of electrical installation work on site.

[Means for solving the problem]

The configuration of the present invention for achieving the above object will be described in detail. In a connected floor box for accommodating outlets arranged on a floor of a building, etc., a corner portion of a box body having a rectangular or rectangular shape. By connecting each other via a crank-type connecting fitting that has two sides that are almost parallel, front and back between the corners of adjacent box bodies
In addition to creating a space in the left-right direction, attach an L-shaped grounding leg to the side plate of the box body to create a space on the bottom surface of the box body, and arrange the bars between the corners of the box body and the bottom surface of the box body. It is a concatenated floor box characterized in that it can be inserted through a class.

〔Example〕

Hereinafter, a specific structure of the concatenated floor box of the present invention will be described in detail with reference to the illustrated embodiment.

FIG. 1 is a plan view showing an embodiment of the floor box of the present invention, FIG. 2 is a front view of the floor box shown in FIG. 1, and FIG. 3 is a partially enlarged perspective view showing an essential part of the present invention.

In the figure, reference numeral 1 denotes a box body having a square or rectangular shape with an upper surface opened, and a side plate 2 of the box body 1 is provided with a knockout hole for attaching a conduit or the like. Further, a lid plate 3 having a mounting hole for mounting a floor article such as a floor outlet is fixed to the top opening of the box body 1 with a screw 4.

According to the present invention, the corner portions 5 of the box body 1 are connected to each other by using the crank-shaped connecting fittings 6, and the space between the corner portions 5 of the adjacent box bodies 1 in the front-rear and left-right directions is set. It is configured to generate, and as a result of connecting using the illustrated crank-type connecting fitting 6,
The mounting surfaces of the conduits, etc. on the box bodies 1 and 1 are connected while maintaining an opening of about 90 degrees.

The crank-shaped connecting fitting 6 has mounting portions 7 and 7 for the side plates 2 and 2 of the box main bodies 1 and 1 on two sides substantially parallel to each other, and an intermediate portion 8 for connecting the mounting portions 7 and 7 is formed. Along the length, there is a front-rear or left-right space between the corner portions 5 and 5 of the box bodies 1 and 1, and the lengths of the mounting portions 7 and 7 are somewhat longer as shown in FIG. Therefore, in the connected state, a space in the left-right or front-back direction is generated between the corner portions 5 and 5, and accordingly, the bar arrangements 11A and 11A are provided near the corner portions 5 and 5 of the box body 1 and 1.
Even when the intersection of B comes, it is possible to obtain the front-rear and left-right intervals enough to insert the reinforcing bars 11A and 11BB (first).
Figure).

In the illustrated embodiment, a relatively long notch 10 through which the shaft portion of the mounting screw 9 can be inserted is formed at the end edge of the mounting portion 7 of the connecting fitting 6, and thus the box body 1 is formed. This is preferable because the front-rear or left-right spacing between the corner portions 5, 5 can be adjusted to some extent, and the connecting work between the box main bodies 1 becomes easy. However, it is not always necessary to use this mounting structure, and for example, a through hole for inserting the mounting screw 9 may be formed near the end edges of the mounting portions 7, 7, or the mounting portion 7 , 7 may be connected to the side plates 2, 2 by welding so that there is a space in the front-rear and left-right directions between the corner parts 5, 5.

In addition, 12 in the drawing is a side plate 2 to which the connecting fitting 6 is attached,
L-shaped grounding legs fixed to the side plates 2 and 2 of the box body 1 other than 2 with screws. The grounding legs 12 are grounded, for example, on a floor formwork at a construction site, and the box body 1 is It is arranged on the floor formwork. By doing so, a space is generated between the bottom surface of the box body 1 and the floor form, so that the bar arrangements can be inserted between the corners of the box body 1 and the bottom surface portion of the box body 1. .

According to the concatenated floor box of the present invention, since the front and rear and left and right spaces can be obtained between the corner portions 5 and 5 of the box main body 1 and 1 as described above, even if the intersection of the bar arrangements 11A and 11B is the corner portion, Even when it comes to, the bar arrangement 11A, 11B
Can be inserted without any trouble, and the bar arrangements can also be inserted into the bottom surface of the box body 1.

Furthermore, since the mounting surfaces of the conduits of the adjacent box bodies 1 and 1 can maintain an opening of approximately 90 degrees, the workability of electrical installation work will be extremely good.

[Effect of device]

As described above, according to the present invention, the floor box can be arranged without any trouble even when the intersections of the reinforcing bars come near the corners of the box body, and the reinforcing bars are cut as in the conventional case. It is possible to save time and effort, and the mounting surface of adjacent conduits such as conduits of the box main body is almost 90
The fact that the degree of opening can be maintained makes it easier to construct the electrical installation.
