Description

RACEWAY HANGER FOR EARTHQUAKE-PROOF

The present invention relates to a hanger for a raceway having the ability to withstand earthquakes, and more particularly, to secure a certain strength to withstand earthquakes, and also to prevent the raceway from falling due to shaking. It's about hangers.

In general, on the ceiling of a large building having a large space such as an underground parking lot, a parking-only building, a factory, a library, or an underground passage, there is a raceway ( race way) is installed.

Recently, by installing lighting equipment and various sensors in one piece along with electrical and communication line wiring, it is possible to reduce the cost and time required for installation work, increase space efficiency and effectiveness, and also prevent safety accidents due to contact interference and friction between wires. In order to minimize electromagnetic interference and noise generated from electric wires, in the event of a fire, emergency broadcasting speakers, emergency induction lights, fire hydrant starting devices, alarm devices, etc. It is manufactured in a form having a certain length so that the power circuit such as the electric power wire such as sensor, indoor fire hydrant, sprinkler, and smoke facility can be separated and wired.

Considering the weight and width of these raceways, hanger rods are usually installed on the ceiling at intervals of 1.5 to 2.5 m, and they are used to hang from the ceiling and support them. There is a problem that is structurally vulnerable to external vibrations, such as the power supply is not smooth due to falling or damaged wires.

Accordingly, in the event of an earthquake, seismic measures for lighting, electrical, and power supply facilities, which have an essential effect on various countermeasures such as securing an escape route in an emergency situation, and As the importance of seismic design has been highlighted, a hanger device for raceways with seismic performance has been proposed.

For example, Patent Document 1 discloses a cable tray support member earthquake-resistant device. This is a cable comprising a pair of vertical members 120 fixed to the ceiling of a building and arranged in a vertical direction, and a horizontal member 110 coupled to the pair of vertical members 120 in a horizontal direction to support a cable tray. The horizontal member 110 by the tray support member 100 and the first hinge part 210 and the first hinge part 210 that are rotatably coupled (moving by changing the direction) with respect to the horizontal member 110 . ) is rotatably connected to the vertical member 120 and is installed at an angle to the connection part 220, and one side is rotatably connected to the connection part 220 and the other side is fixed to the ceiling, the connection part 220 It is made of a seismic device 200 including a second hinge part 230 for rotatably supporting the ceiling with respect to the earthquake flexibly in response to the movement in various directions to absorb the vibrations of the earthquake.

However, since the vertical member 120 is a structure that is fixed to both ends in a bolting manner along the longitudinal direction of the horizontal member 110, if this is applied to a method of connecting and installing several raceways, maintenance and installation work is It is quite difficult and has inconvenient limitations.

On the other hand, the electric wire duct clamp is disclosed by patent document 2. As shown in FIG. 1 , this includes a hanger rod 100 , a body 101 formed to be movable up and down while engaged with the thread of the hanger rod, and a rotation bracket 102 rotatably formed around the support shaft 110 . ) and a support bar 103 in which the support shaft 110 and the body 101 are integrally fixed to the upper part and a locking jaw 105 is formed to hang the electric wire duct 200 inside the lower part.

However, since such a conventional clamp simply supports the wire duct (raceway) by hanging it on the protrusion 105, even when an earthquake occurs, the wire duct easily falls out of the support bar 103 and there is a high risk of falling. There is this.

A long hole 314 into which the lower end of R) is inserted is drilled.

That is, the support bracket 310 is made in a '∩' shape, and is coupled by double tightening the nut (N) having a diameter larger than the long hole (314) while adjusting the height hanging on the hanger rod (R).

And the lower portion of the left side portion 312 and the right side portion 313 is formed with close contact portions 315 that are in close contact with both sides of the upper surface of the raceway W in the horizontal direction, and lock holes 316 are formed on both sides thereof. .

The levers 320 are respectively attached to both sides of the lower sides of the support brackets 310 by pin (P) joints, and on both sides of the upper portions of the levers 320, they are elastically inserted into or removed from the lock holes 316 by elastic deformation to lock them. Locking projections 321 for maintaining and unlocking the state are formed, respectively.

That is, the front and rear edges of the lever 320 are formed in a shape having a curved surface as if surrounding a part of the left surface portion 312 or the right surface portion 313 , and a locking protrusion 321 is formed on each of the bent surfaces. It is formed to protrude toward the lock hole 316 of the left side part 312 or the right side part 313 .

In addition, a handle 323 curved outwardly is formed on the upper portion of the lever 320 to secure the ease and convenience of opening and closing the lever 320 .

Therefore, the lever 320 rotates about the connection pin P with respect to the support bracket 310 so that the lock protrusions 321 on both sides thereof are elastically fitted into the lock holes 316 of the support bracket 310 or By pulling out the locking protrusions 321 from the locking holes 316, the lower portion of the latch 330 is inserted into the locking groove G of the raceway W to stably maintain or release the hooked state.

That is, according to the operation of rotating the lever 320 in a locked state, the close contact portion 315 of the support bracket 310 presses the upper edge of the raceway W while the clasp 330 engages the locking groove G of the raceway. ), so that the middle part of the raceway (W) does not shake, it can be fixed and supported on the hanger rod (R).

Here, the upper surface portion 311 of the support bracket 310 is preferably treated or has a shape and structure to prevent the nut (N) from loosening by itself.

And the hanger rod (R) is a round rod used to hang and support the raceway (W) from the ceiling, and a screw is made at the end so that the nut (N) can be tightened.

On the other hand, the support bracket 310, the lever 320, and the clasp 330 may be formed to suit the purpose of use by applying a compressive force to the metal plate and plastically deforming it to form a predetermined curved surface.

The main action and operating principle of the inner running gusset 300 for a raceway according to an embodiment of the present invention configured as described above will be described as follows.

First, it is possible to simply and easily install the raceway (W) to the hanger rod (R) by an opening/closing operation of rotating the lever 320 without a separate tool.

At this time, since the locking protrusion 321 of the lever 320 is elastically inserted into the locking hole 316 of the support bracket 310 by elastic deformation to maintain the locked state, the lever 320 is subjected to an earthquake or external force such as an impact. It is possible to improve the installation stability by preventing the lock from being released by itself.

Moreover, as shown in FIG. 4, the support bracket 310 is firmly in close contact with the upper surface edge of the raceway W according to the locking operation of the lever 320, and at the same time, the clasp 330 locks the raceway W. The raceway (W) can be fixed and supported more firmly because it is elastically inserted into the locking groove (G) to maintain the operation state of pressing and pulling in opposite directions.

That is, by changing the angle of the clasp 330 connected to the lever 320 by a pin (P) joint, pull the support bracket 310 to apply a force to adhere to the raceway (W), and use the clasp 330 to the raceway ( Since it is a structure that pulls and locks W), it is possible to firmly fix and support the raceway (W) by the action of frictional force.

Therefore, even if several raceways (W) are connected and installed, a certain strength to withstand earthquakes is secured, and even if the building shakes during an earthquake, etc., the raceway (W) is firmly fixed and supported to prevent torsion deformation. In addition, it is possible to prevent the risk of disasters due to the departure and fall of the raceway (W).

On the other hand, as shown in FIG. 5 , the inner running guide 300 for a raceway according to another embodiment of the present invention includes the left side part 312 of the support bracket 310 and the Through holes 317 passing through each other are formed in the right side portion 313 , and pin holes 322 are formed at positions corresponding to the through holes 317 in the locked state of the levers 320 .

Then, the through bolt 340 is passed through the pin hole 322 of the lever 320 and the through hole 317 of the support bracket, and is fixed to the raceway W by tightening it with a tightening nut 341 from the opposite side.

That is, since the through bolt 340 and the tightening nut 341 have a double locking structure of the lever 320, the lever 320 is automatically released by an external force such as an earthquake or an impact to prevent the locking state from being released. It is possible to keep the installed state of the raceway (W) safer and more robust.

Here, among the components related to the inner jog 300 for raceway according to another embodiment of the present invention, components having the same or similar operational effects as those of the above-described embodiment use the same reference numerals as those of the above-described embodiment, Repetitive and detailed descriptions of these will be omitted.
