Description

[Detailed description of the invention] This invention relates to a separator support fitting for cable racks, and when electrical wiring is installed in structures such as factories and buildings, cable racks are used in which the cables are bundled and supported. The present invention relates to a separator support fitting that allows a separator that partitions the inside of a cable rack according to the amount of cables or for each type of cable to be fixedly supported on the cable rack simply, quickly, and reliably.

Conventionally, when wiring cables using a wide cable rack, it was necessary to use only one half of the rack when the number of wires was small, or to separate several wires for different types of instruments. At this time, the interior of the cable rack is divided using long plate-like separators for partitioning.

This separator is fixed to the sub-girder part of the cable rack by welding, screwing, etc.
Therefore, in addition to poor work efficiency, once the separator was fixed to the child girder, it was extremely difficult to change the compartment space.

In order to solve this problem, the applicant proposed the
Various separator support fittings have been proposed in Publications No. 8 to 40871 and No. 51-22313, but all of them are set from above the separator so as to straddle it, making the fitting itself large and difficult to handle. It was recognized that there were drawbacks such as being troublesome and having to separately prepare separators of various sizes depending on the shape and size of the separator.

Therefore, in consideration of the above points, this invention was designed to make the metal fittings themselves smaller and more versatile. In a separator support fitting for fixing and supporting a separator having a cross-section with a cross section that partitions the inside of a cable rack having a substantially ladder shape in plan view on a sub-girder, an abutting piece that comes into contact with a side surface of an upright partition plate of the separator is provided upright. At one end of the main holding piece, an engaging piece that engages with the lower end of the child girder is bent and raised, and the main holding piece has an L-shape on the side, and a tightening piece into which the tightening fixing screw inserted through the main holding piece is screwed. and a U-shaped clamping support body which is connected to the upper and lower edges of the main clamping piece so that the engaging pieces that engage with the horizontal mounting substrate of the separator face each other.

An embodiment of this invention will be described below with reference to the drawings.

L shown in the figure is a cable rack, which is constructed so that a plurality of child girders 21 are installed between a pair of parent girders 20 facing each other to form a roughly ladder shape with reinforcement taken into consideration. The main girder 20 has a generally bow-shaped cross section, and the child girder 21 has a concave upper surface and a generally inverted U-shaped cross section with an open bottom.

In addition, S is a separator formed in a cross-sectional shape from the upright partition plate 30 and the horizontal mounting board 31 placed on and in contact with the sub-girder 21 in order to partition the inside of the cable rack L. be.

Here, the separator S is fixedly supported on the cable rack L by the metal fitting main body 1 having an angular shape when viewed from the side, and the fastening member 8 having a U-shape when viewed from the side.

The metal fitting body 1 has an engagement piece 5 that engages with the lower end of the child girder 21, which is bent and raised at the 2 ends of the main holding piece, on which the abutment pieces 4 that come into contact with the side surfaces of the partition plates 30 of the separator S are erected. It is.

The main holding piece 2 in the illustrated example is formed into a substantially rectangular plane shape in order to achieve further stability when attached, and the abutment piece 4 is placed inside the cable rack L, that is, on the child beam 21. At the protruding part, in order to effectively prevent damage to the cable W sheathing through which the wire is passed, both sides of the protruding part are cut obliquely to form a substantially trapezoidal shape from the front, and are slightly rounded. There is.

Then, the engagement piece 5 should be engaged with a part of the child spar 21 when the metal fitting main body 1 is attached to the child spar 21 from below the child spar 21 (as shown in the figure, Since it has a substantially inverted U-shaped cross section, it is engaged with the lower edge of one side thereof.

At this time, as shown in FIG. 4, in order to ensure a reliable stopping state, the separator S is placed orthogonally on the child spar 21, and the side part of the child spar 21 itself has a slight wall thickness.
Between the contact piece 4 and the engagement piece 5, which are arranged orthogonally to each other,
A child beam 21 is attached to the end of the main holding piece 2 along the width direction of the contact piece 4.
A gap is provided corresponding to the wall thickness of the side part.

In other words, the side portion of the child spar 21 is sandwiched between the gaps when viewed from the length direction of the child spar 21, and the inner surface of the engagement piece 5 is brought into contact with the inner side of the side, and the base of the abutment piece 4 is held in place. The side edges are formed in a vertical line shape so as to be in close contact with the outer surface of the side part.

In addition, as shown in the figure, by bending and erecting the engaging pieces 5 at both ends of the main holding piece 2 so that they face each other, even if the separator S is attached to the separator S from either the left or the right, one of the engaging pieces 5 21, thereby improving usability and greatly improving work efficiency.

The fastening member 8 includes a fastening piece 10 into which the fastening fixing screw 6 inserted into the main holding piece 2 is screwed, and the mounting board 31.
The engaging pieces 12 that engage with the main fastening piece 9 are arranged facing each other on the upper and lower edges of the main tightening piece 9.

Therefore, the main holding piece 2 is provided with a through hole 3 of a slightly large diameter through which the tightening fixing screw 6 is inserted, and as shown in FIG. Tighten the fixing screw 6 so that it can be tilted freely.

Note that 11 is a screw hole provided in the tightening piece 10.

As shown in FIGS. 3 and 4, when attached to the separator S, the side edges of the tightening piece 10 and the main tightening piece 9 are brought into contact with the outer surface of the child beam 21, and the hooking piece 12 The tightening piece 10 is formed longer than the one shown in FIG. By doing so, it is preferable to improve the attachment stability of the fastening member 8 to the fitting main body 1, child beam 21, and separator S.

Furthermore, by inserting the tightening fixing screw 6 into the fitting main body 1 and screwing it into the tightening holding body 8 in advance, the fitting main body 1 and the tightening holding body 8 are integrally connected and connected, and both are connected at an angle of 1°8. mutual estrangement,
To prevent loss and facilitate ease of handling.

Next, to explain the use of this, an example is: First, separators S are placed orthogonally on the child beam 21 in correspondence with the compartment size of the number of cables W to be wired and stored in the cable rack L. On the other hand, the tightening fixing screw 6 is inserted through the metal fitting main body 1 and screwed into the tightening fixture 8, so that both 1 and 8 are set together.

Next, insert the hooking piece 12 from below the child girder 21 into the separator S.
At the same time, with the contact piece 4 in contact with the side surface of the partition plate 30 of the separator S, the engagement piece 5 is engaged with the lower end of the child beam 21. By aligning them, the metal fitting main body 1 is attached.

Thereafter, the tightening fixing screw 6 is screwed in, and in connection with this screwing action, the tightening fixing body 8 and the metal fitting main body 1 are drawn together, and the separator S is brought into pressure contact with the child beam 21.

Therefore, as the tightening fixing screw 6 is screwed in, the fitting body 1 and the tightening support body 8 are attracted to each other, and the former 1 is engaged from below the child girder 21 via the engagement piece 5, and the latter 8 is engaged from below. Piece 1
2, it is engaged with the separator S and from above the child girder 21,
They are strongly approached with the child spar 21 interposed between them, and the child spar 2
A separator S is firmly supported on top of the separator S.

Moreover, both the metal fitting body 1 and the fastening support body 8 have child beams 21.
Since it is attached only to the cable rack L, the cable rack L does not have to be large enough to straddle the separator S as in the past, and the internal space within the cable rack L can be used extremely effectively without reducing the wire passage volume.

In addition, the metal fitting body 1 is engaged with the separator S from below the child spar 21, and the tightening holding bodies 8 are respectively attached from above the child spar 21, and both are screwed together with the tightening fixing screws 6. Since they only need to be connected, handling is easy and work can be carried out extremely efficiently.

Further, the abutment piece 4 erected on the main holding piece 2 of the fitting body 1 is placed on the side surface of the erected partition plate 30 of the separator S, and the engaging piece 12 of the fastening support body 8 is placed on the sub-girder 21. Since it is engaged with the horizontal mounting board 31, the mounting board 31 is brought into pressure contact with the upper surface of the child beam 21 as the tightening fixing screw 6 is screwed in, and the separator S itself is in an upright state. Child digit 2
It is firmly supported on the top of the separator S, does not wobble at all due to external shocks or vibrations, and can be used regardless of the size of the separator S itself, making it extremely versatile.

Since the fastening support body 8 is constructed by connecting the top and bottom edges of the main fastening piece 9 with the fastening piece 10 and the engaging piece 12 facing each other, the fastening fixing screw 6 can be tightened against the fastening piece 10. The screwing is directly transmitted to the engaging piece 12 via the main tightening piece 9 and acts as a pressing force on the mounting board 31.

At this time, the length of the tightening fixing screw 6 itself, and also the length of the tightening piece 1
It can be used even if the height of the child girder 21 itself changes slightly depending on the screwing distance with respect to 0, so it has great versatility, and when screwing in, it prevents the tightening solid support 8 from opening due to over tightening. Even if the fixing screw 6 is loosened after installation, there is no risk of it falling off, and the device is extremely stable and safe.

In addition, since the metal fitting body 1 is formed in a curving shape on the side, and the fastening support body 8 is formed in a substantially U-shape on the side, both can be obtained as one piece by cutting and bending a thick plate material as appropriate. and can be provided at an extremely low cost.

As explained above, according to this invention, in a cable rack that connects and supports cables in structures such as factories and buildings, the inside of the rack is divided into sections according to the amount of cables and cable types. Fixed support to the rack can be performed simply, quickly, and reliably. Moreover, since the lower part of the separator is supported by the child girder, it is highly versatile and reduces the cable accommodation space in the cable rack. In addition, it does not damage the cable sheathing, the installation work and even the rezoning are extremely simple, the work can be carried out efficiently, and the structure is simple and can be provided at low cost. It is.
