Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support section for a vertically laid bus duct useful as a vertical main line in buildings and other structures.

Generally, the supporting part of this type of bus duct is an angle 20 installed on the floor F, as shown in FIGS. 1 and 3.
Between a plurality of support bolts 10 vertically installed with nuts at predetermined intervals, and a bus duct 30 vertically erected through the through hole Fh of the floor F, A method is adopted in which a channel-shaped support member 1 bent in an L-shape is connected and supported, and in this case, one piece 1b of the support member 1 is connected to the side of the bus duct 30 with the L-shaped bent part 1a as a boundary. This fixation allows the support bolt 10 to be inserted vertically through the other piece 1c that protrudes from the side of the bus duct at a right angle. The bus duct is supported on the floor by, for example, placing the member 1 on a certain spring 11.

By the way, as is well known, this type of bus duct consists of a rectangular duct with a rectangular cross section.
There are two types of support surfaces that communicate with the opposing support bolts 10, one on the short width side and one on the long width side, and therefore two types of support methods are required.

FIG. 1 shows an example in which the short width side of the bus duct 30 is used for support, while FIG. 2 is an example in which the bus duct 30 is provided in support on the long width side.

This separate support method is used when it is not possible to provide support on the short side of the bus duct, as shown in Figure 1, due to the proximity of walls or the presence of obstacles on the short side of the bus duct. This is to provide support by moving the support element to the longer width side of the bus duct as shown in FIG.

However, as is clear from the figure, in the double support method, the support member 1
, 1' are changed, and 1' must be longer than member 1, which requires at least two types of support members.

It would be fine if it was just that, but angle 20.
The design of the support members 1, 1' will also differ depending on how the support bolts 10 and 20' are attached.

By the way, the angle is 20.20' and the support bolt is 10.
The installation is based on the location of the steel frame of the building or the location where
It depends on the number of bus ducts used and may differ even within the same building.

Therefore, it is currently not possible to design the support elements of the bus duct until the installation of the angles and support bolts is finally completed, and even though speedy work is required these days, subsequent indoor wiring work is also delayed. This will lead to a situation that is clearly disadvantageous.

The present invention has been made in view of such a situation, and its purpose is to install angles and support bolts regardless of whether they are located on the short or long side of the bus duct. It is an object of the present invention to provide a support member of this type that can be freely supported in one type of shape.

That is, the support member of the present invention, as shown in the embodiment in FIG.
A vertically elongated piece 100b is bent into an L-shape 100a with each piece separated from both longitudinal edges of the piece 100b.
The longitudinal width of the piece 100b is set to be larger than the width of the short side of the bus duct side, and the separated pieces 100c and 100c are separated from each other. In between, a concave notch 200 that reaches the inner surface of the piece 100b from the protruding tip side of the piece 100c is set with a width at least equal to or larger than the width of the short side of the bus duct, and is vertically long. The piece 100b is used as a fixing piece to the short width side of the bus duct, and the pieces 100c, 100c are separated from each other.
is formed as a protruding piece through which each of the plurality of support bolts vertically inserted is installed at a predetermined interval based on the fixation of the fixing piece 100b to the short width side of the bus duct. .

Such a support member 100 is made, for example, by cutting an angle steel material into a predetermined length as shown in the example drawings to obtain a basic shape, and then cutting the substantially central part of one piece so that it reaches the bent part. By cutting it to a predetermined width, it is possible to obtain the desired form in which the recessed portion 200 is formed.

However, it can also be created in other ways.

For example, the basic members to be supplied include a piece corresponding to the fixed piece part 100b and a protruding piece part 100c.

The desired member can be obtained by separately preparing the parts corresponding to 100c, positioning each part so as to define a predetermined recessed part 200, and welding and joining them together.

5 and 6 show two embodiments of a bus duct support section constructed using the support member according to the present invention. In the case of FIG. 5, the angle 20 and the support bolt 10 are attached to the bus duct 30. This is an example in which the angle 20' and the support bolt 10 are installed along the short width side of the
' is an example in which the bus duct 30 is installed along the long side.

According to the present invention, in the former case, the outer surface of the fixing piece part 100b is applied while facing the short width side of the bus duct 30, and fixed by the port I-B, and by that fixing. A protruding piece portion 100c protrudes outward at a right angle on the short width side of the bus duct 30.

Support bolt 10 erected on angle 20 at 100c
．． 10 can be inserted vertically to support the bus duct 30. On the other hand, in the case of FIG.
The fixing piece part 100 is housed so as to vertically pass through the side part of the
The inner surface of b' faces the short width side of the bus duct 30 and is fixed with the bolt B, and at the same time, the long side of the bus duct 30 is fixed to the short width side of the bus duct 30. A protruding piece portion 100c” that can protrude along.

A support bolt 10', which is erected on an angle 20' at 100 c', can be inserted vertically to provide support.

In this way, simply invert the support member 100 and connect the bus duct 3.
By simply fixing to the short width side of the bus duct, common support can be achieved regardless of whether the support bolt is installed on the short or long side of the bus duct, so it can be made into a single product without making different types. can.

Further, according to the present invention, it is also applicable to changing the size of a bus duct.

That is, the width between the pieces 100c and 100c of the recessed notch 200 is set wider than the short side width of the bus duct size that can be inserted normally, and even if the size of the bus duct changes, It can be stored in a recessed part, and there is no need for one specifically tailored to the size of the bus duct, and it can be prefabricated.

The bolt insertion holes (see Fig. 4) necessary for the members of the present invention can be easily drilled with a drill or the like in accordance with the actual situation at the site, so they can be made as appropriate even when there is a large deviation in the position of the angle, etc. can be adapted.

In addition, when fixing the member L of the present invention to the side of the bus duct 30, as shown in FIGS.
0b and 100b' are directly fixed to the short width side of the path duct 30, thereby contributing to a reduction in the number of installation steps.

However, similar to the conventional method, a light beam (see Fig. 3, 12) is used, and this is attached to the fixing pieces 100b, 100b' and the bus duct 3.
Of course, it may be fixed by being interposed between it and the short width side portion of 0.

Further, the member 100 of the present invention may be provided with a reinforcing material or may have a reinforcing portion formed therein to the extent that it does not interfere with the purpose of use, such as fixing to a bus duct or inserting a support bolt.

As explained above, in the support member of the present invention, the width in the longitudinal direction of the fixing piece that can be fixed to the short width side of the bus duct is set larger than the width of the short width side of the bus duct, and the fixing piece A state in which protruding pieces that are bent in an L-shape and integrally protrude from the longitudinal side edges of the fixing piece and through which a plurality of support bolts installed at predetermined intervals are inserted are separated from both longitudinal ends of the fixing piece. Furthermore, between the separating protruding pieces, a recessed part is formed that reaches the side edge of the fixed piece from the protruding tip side of the protruding pieces, at least the short width of the bus duct. Set the width to be wider than the side width, and select either the protruding side of the fixing piece for the short width side of the bus duct or the opposite side. By fixing them facing each other, the protruding piece portion protrudes toward either the short width side or the long width side of the bus duct.

Therefore, according to the support member of the present invention, when the positions of the plurality of support bolts erected on the angle at predetermined intervals are on the short width side of the side part of the bus duct, the short width side of the bus duct approaches the wall. Even when the support bolt is installed separately on the long side of the bus duct because there is not enough space, the fixing piece can be fixed to the short side of the bus duct. The configuration in which the protruding piece protrudes to the short width side and is connected and supported by the support bolt is made such that the bus duct is passed through the recessed part by simply inverting the fixing piece without changing the mounting position. By fixing the protruding piece with the bus duct, the protruding piece moves back from the short width side of the bus duct and protrudes into a wide space within the long side of the bus duct, allowing communication and support with the support bolts. When providing support by erecting support bolts at 90° different positions on the short width and long width of the bolt, it is not possible to use members with different shapes and dimensions to connect and support them with separate specifications, as in the past. The fixing work can be done in a unified manner from the short width side of the bus duct using common parts without using the bus duct, and the support installation of the bus duct can be done easily and quickly, improving work efficiency and making it possible to make it into a single product. Therefore, it is possible to produce large quantities and prepare for installation, which has great benefits such as facilitating inventory management and contributing to cost reduction.
