Description

Sleeve Joint connector for cable tray {Sleeve Joint connector for Cable-Tray}

The present invention relates to a sleeve joint connector for a cable tray for connecting a cable tray positioned by a granular layer to a sleeve by a technique relating to a sleeve joint connector for a cable tray.

In the process of constructing the building, slabs (a structure made by pouring concrete into layers) are formed to connect the cable trays vertically and pass between the slabs.

The slab requires an upwardly and downwardly opened sleeve to receive the cable tray to secure the cable tray. In order to fix the sleeve to the opened passage of the slab, the support frame is horizontally protruded upward and downward and fixed by bolts.

The sleeves can be manufactured to a certain size according to the specification, or they can be produced by custom production. Since the slab is poured by the concrete, the height error always occurs in the slab process.

FIG. 1 is a view showing an example of installed sleeves according to a granular layer, in which a cable tray 20 is vertically passed between slabs 10, and a cable tray is fixed to a slab 10 by a sleeve 100.

In this case, there is always a difficulty in fixing the sleeve because the height of the sleeve does not match the height of the sleeve due to the error of the thickness of the slab. Also, since the sleeve is a connection port for connecting the cable tray, a grounding structure by electric leakage is needed.

FIG. 1 is a view showing an example of a sleeve installed by a granular layer. In the sleeve 100, a cable tray 20 is installed through a slab 10 to be vertically connected, opened upward and downward, Is formed.

FIG. 2 is a perspective view of a sleeve joint connector for a cable tray showing an example of the present invention, and FIG. 3 is an installation cross-sectional view of a sleeve joint connector for a cable tray.

Referring to FIGS. 2 and 3, the present invention can be implemented as follows.

As shown in FIGS. 2 and 3, a plurality of cable trays are accommodated on both sides of the cable tray 20 between a pair of mutually spaced apart spaces in the sleeve 100 to be vertically connected, The joint panel 500 is fixed to the joint panel 500.

That is, the joint panel 500 supports the inside of both sides of the sleeve 100, and the cable tray 20 can be slidably moved between them.

The joint panel 500 includes an intermediate plate 540 fixed to the inner surface of the sleeve 100 to be fixed to the sleeve and a cable tray 20 extending upward from the intermediate plate 540, And a lower plate 560 extending below the intermediate plate 540 and coupled with a cable tray 20 located at a lower portion of the slab.

As shown in FIG. 2, the upper plate 520 and the lower plate 560, which are formed so as to step outward from the middle plate 540 in an upwardly and downwardly manner, are formed to be in close contact with the upper and lower surfaces of the sleeve 100 And it is possible to secure a sufficient space for the cable tray 20 to be drawn in.

A bolt fastening hole 542 is formed in the intermediate plate 540 and is fixed to the slab 10 through the sleeve 100 in the joint panel 500 by an anchor bolt which is a fastening part 200.

The upper plate 520 and the lower plate 560 extend inwardly bent at one end to form auxiliary plates 522 and 562 which are in close contact with the cable tray 20 inserted between the joint panels.

The auxiliary plates 522 and 562 are formed on the top plate 520 and the bottom plate 560 so that the front side and the back side of the joint panel 500 provided on both sides of the inside of the sleeve 100 are closed and the front side is closed, So that the cable tray can be retracted to the rear side.

It is also in close contact with one side of the cable tray drawn by the auxiliary plates 522, 562 to support it.

The auxiliary plates 522 and 562 can be formed on both side edges of the upper plate 520 and the lower plate 560. At this time, the auxiliary trays 522 and 562 may be extended while the cable tray is inserted, and then bent and closely contacted with the cable tray.

A bolt hole is formed in the upper plate 520 and the lower plate 560. Particularly, a bolt hole having a long upper and lower lengths is formed on the lower plate so that the coupling position of the cable tray located under the slab can be adjusted by bolts Therefore, there is an advantage that the installation error of the cable tray can be corrected.

The upper plate and the lower plate are provided with a copper plate 320, and the jumper wire is further connected to the copper plate so as to be grounded. Thus, the electrical leakage of the cable tray can be grounded.

The copper plate is composed of a lower copper plate having a bolt hole connected to the upper plate and a handle plate protruding from the upper portion of the lower copper plate so as to be held by the operator so that the operator grips the inside of the upper plate with the handle plate, It can be connected to the lower copper plate by bolts, thus enhancing work convenience.

4 is a cross-sectional exemplary view showing a sleeve joint connector for a cable tray according to another embodiment of the present invention.

The sleeve 100 is divided into at least two or more along the up and down direction. In FIG. 2, the sleeve 100 is divided into an upper portion and a lower portion, and the divided sleeves 120 and 140 are overlapped with the lower portion of the upper sleeve and the upper portion of the lower sleeve.

The lower end of the sleeve 120 divided into the upper part of the divided sleeves 120 and 140 is fitted to and overlapped with the upper end of the sleeve 140 divided into the lower part, .

A coupling part 200 is further formed to penetrate the side surface of the overlapped portion of the divided sleeves 120 and 140 to engage with the cable tray 20 to join the divided sleeves 120 and 140. Here, the fastening part 200 is fixed to the final slab 10 through the sleeves 120 and 140 divided in the cable tray as an anchor bolt.

At this time, a jumper wire is further formed, which is electrically connected to the coupling part 200 to be electrically connected to the cable tray 20 and grounded, so that an end of the jumper wire is connected to the reinforcing bar or the ground bar to ground the cable tray 20 It is possible.

The sleeve 100 is formed with a slotted bolt hole in the support frame 110 so that the sleeve 100 adjusts the position of the sleeve 100 in the horizontal direction inside the slab 10 and bolts the bolt to the upper portion of the slab 10 So that the sleeve 100 is fixed.

In the meantime, a longitudinal slot is formed in the divided sleeves 120 and 140 so that the overlapped lengths of the divided sleeves 120 and 140 are adjusted to be fixed to the coupling part 200, Can be adjusted.

The reason why the overall length of the sleeve 100 is adjusted is that the height error is generated because the slab 10 is poured into the cement and the height of the sleeve 100 is adjusted to correspond to the height error, have.

5 is a view showing a modified example of the present invention.

5, a sleeve 100 is provided inside the slab 10 to vertically connect a plurality of cable trays 20 and is opened upward and downward, and has a support frame coupled to the slab 10 at an upper end and a lower end. A pair of joint panels 500 are installed inside the sleeve 100. The joint panel includes an intermediate plate fixed to the sleeve and closely attached to the inner surface of the sleeve, An upper plate coupled to the outer surface of the cable tray located on the upper portion of the slab and a lower plate coupled to the inner surface of the cable tray extending below the intermediate plate and located at the lower portion of the slab.

Here, the upper plate of the joint panel 500 is stepped inward to be coupled to the inside of the cable tray, and the lower plate is stepped outwardly to the intermediate plate to be coupled inside the cable tray to prevent the flexure of the joint panel 500 Respectively.

The sleeve connector for a cable tray according to the present invention described above is not limited to the above-described embodiments, and various modifications and changes may be made without departing from the spirit and scope of the present invention. It should be regarded as belonging to the scope of protection of the patent claims to the extent that it can be variously changed by anyone who possesses it.
