Description

Clamp for cover fixing of cable tray {CLAMP FIXING FOR COVER OF CABLE TRAY}

The present invention, for example, relates to a clamp (CLAMP) for fixing the cover to the cable tray that is supported by the self-weight when wiring the communication cable or voltage cable in underground cavity or factory, building or tunnel, etc. In order to prevent rain or foreign matters from accumulating or damaging the cable, the cover for the cable tray used to prevent the cable from shaking and falling from the cable tray. The present invention relates to a clamp for fixing a cover of a cable tray which can be more stably fixed.

In general, when a communication cable or a voltage transmission cable or the like is routed along a ceiling or a wall of an underground cavity or a building or a tunnel, the cable may sag downward due to its own load and the cable may be damaged by vibration. In order to prevent the cable from sagging and vibration, a heavy metal cable tray is usually used to support the cable. In this case, a plurality of struts arranged at regular intervals on a ceiling or a wall are provided with corresponding channels. By fixing it horizontally and placing a trapezoidal cable tray on the plurality of channels and fixing it with a fixing bracket, the cable to be wired and installed in the cable tray is not sag and damage by vibration is prevented.

However, the cable tray as described above may damage the aesthetics by the cable installed inside after the wiring and installation is completed. Especially, since the upper part is opened, rainwater or foreign matters may fall from the top, which may damage the cable or cause a lot of fine dust. As a result, electric leakage and short-circuit may occur, which may cause a fire, as well as a case where the communication is disconnected when the cable is used for communication. Therefore, the cable tray manager must not only remove dust and foreign matter accumulated on the cable periodically, but also have difficulty in managing the cable at any time. Therefore, the cable tray manager is wrapped with a plate-like cover and then clamped. The cover is fixed by fixing means to protect the cable from rain or foreign matter.

In general, fixing clamps for fixing a flat cover to a cable tray include an out side clamp and a substantially "c" shaped clamp applied to the present invention.

The former outside clamps bend the rectangular plates vertically, and then bend the ends upwards back into the hook shape, sandwiching the flat cover and the cable tray beams at the ends of the hooked sections, and then tightening the bolts. The end of the bent portion and the end of the bolt by pressing through the plate body to compress the cover and the beam is fixed, which is inconvenient in the fastening process, and also difficult to manufacture the clamp, as well as manufacturing cost It is pointed out as a problem that takes a lot.

And the clamp for fixing the cover of the cable tray applied to the latter of the present invention, unlike the outer clamp, the fastening process is simple and easy to manufacture, while the bolt on the flat plate cover to the beam of the cable tray Tightening the bolts causes the two wings of the "c" rectangular plate to not be pressed against the top and bottom of the cover, but rather outward (bent), and also to the center of the vertical neck that connects the two wings. There is a risk that the cover may not be squeezed and secured to the cable tray stably in the outward direction without overcoming the tightening force of the cable, which may cause the cover to swing or fall off or fall off after the fastening.

Therefore, while providing a cover fixing clamp that heals the conventional problems as described above in terms of cost and a cover fixing clamp in terms of reliability, and a simple structure and assembly in terms of reliability, the cover is more stably fixed to the cable tray. It is desirable to.

Accordingly, an object of the present invention is to provide a clamp for fixing a cover of a cable tray, which allows a flat and strong cover to be secured to a cable tray to which a cable is wired and installed. "" Bending both ends of the vertical neck having a constant width and length at right angles to have a shape to form a wing, and the outward reinforcing protrusions and inward reinforcing protrusions on the inner side of the bent portion and the outer side of the vertical neck, respectively Protruding inward outward, when tightening the bolt to the nut formed on any one of the wing portion of the wing portion, both the wing portion and the vertical neck by the inner and outward reinforcing protrusion pieces, the elastic force to the bolt without bending This is achieved by applying a flat cover to the beam of the cable tray strongly.

It is another object of the present invention to provide a clamp for fixing the cover of a cable tray, which can greatly simplify the construction of the clamp to shorten the fastening time and lower the manufacturing cost of the component, and the cover fixing clamp is the outer side of the vertical neck. By forming the inner and outward reinforcing protrusion pieces projecting on the inner side of the face and the bent portion by a simple punching operation.

Further objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

According to the clamp for fixing the cover of the cable tray according to the present invention for achieving the above objects, the beam is installed horizontally to face each other on both sides of the channel, and the flat cover mounted on the upper surface of the beam of the bolt In clamps that are clamped and clamped by tightening:

The clamp is,

(1) formed of a vertical neck having a constant width and length so as to have a "c" shape as a whole, and bent at right angles at both ends of the vertical neck, and both wing portions having a nut part at one center thereof;

(2) an outwardly reinforcing protrusion piece which protrudes and is formed on an inner boundary surface between the vertical neck and both wing portions, and prevents both wing portions from bending outward when the bolt is tightened through the nut portion formed on the one wing portion; And

(3) includes an inwardly reinforcing protrusion piece that protrudes and is formed perpendicular to the outer surface of the vertical neck to prevent bending of the vertical neck when the bolt is tightened.

Optionally, the outwardly reinforcing protrusion pieces formed on the inner boundary surface of the vertical neck and both wings are protruded and formed inward at least two or more inwards by punching the outer boundary surface.

Optionally, the inwardly reinforcing protrusion pieces are characterized in that they protrude outwardly and have a predetermined length and width by punching the inner surface of the vertical neck.

In this way, when the bolts are tightened firmly to fix the flat cover to the beam of the cable tray, the two vertically bent wings are intended to be stretched vertically in the opposite direction of the bolt tightening direction, that is, along the threads of the bolts. It can be seen that the outward reinforcement protrusion piece prevents the tension function while the inward reinforcement protrusion piece prevents the vertical neck from bending inward.

As a result, the flat cover can be fixed to the cable tray to which the cable is wired and installed more stably without shaking and falling, and the bolts are not bent and both wings and vertical necks are not bent, making the work more convenient. There is an advantage that the formation and fastening time is greatly shortened.

And the metal clamp 20 for pressing and fixing the flat cover 30 to the beam 70 of the cable tray 10, as shown in Figs. An upper wing portion having a vertical neck 22 having a predetermined width and length, and an upper end portion of the vertical neck 22 bent at a right angle and having a nut portion 24c for fastening the bolt 50 at the center thereof. 24) and the lower end of the vertical neck 22 is bent at a right angle with the same width and length as the upper wing 24, when the bolt 50 is tightened, it is pressed against the lower surface of the beam 70 to support The lower wing 26 is made large.

And the nut part 24c formed in the upper wing part 24 by protruding inwardly and formed in the upper wing part 24 by the punching of the outer surface which opposes on the interface surface of the vertical neck 22 and the upper and lower wing parts 24 and 26. Two outwardly reinforcing protrusion pieces 24a, 24b and 26a and 26b which prevent the upper and lower wing portions 24 and 26 from bending outward when tightening the bolt 50 through the Has In addition, the outer surface of the vertical neck 22 is protruded and formed outwardly with a predetermined length and width by the punching of the inner surface opposite thereto, and inward to prevent bending of the vertical wood 22 when the bolt 50 is tightened. It has the reinforcement protrusion piece 22a.

The cover fixing clamp 20 of the cable tray according to the present invention made as described above will be described in more detail with reference to FIGS. 1 to 4.

After fastening the pivot nuts 62 of the channel cover 60 to the male threads 92 of the plurality of struts 90 mounted perpendicular to the ceiling, the respective channels 40 on the channel covers 60 are secured. Fix it by inserting both ends of it. Then, as shown in FIGS. 1 and 4, the two beams 70 which are kept at regular intervals by the plurality of supports 74 are placed on the channel 40 so as to face each other, and then the fixing brackets 80 are provided. The beam 70 of the cable tray 10 is stably fixed.

Thereafter, the cover 30 is placed on the upper surface of the wing portion 72 of the beam 70 formed in the cable tray 10, and the bolt 50 is inserted into the clamp 20 of the present invention to tighten the cover ( 30 is stably pressed and fixed to the beam 70.

In the above, a process for fixing the flat cover 30 to the beam 70 of the cable tray 10 with the clamp 20 will be described. First, as shown in FIGS. 1 and 4, the cover 30 is shown in FIG. In a state where the cable tray 10 is mounted on the two beams 70 and positioned horizontally, the clamp 20 having the shape of “c”, as shown in FIG. 2, is inserted into the cover 30 and the beams 70. The upper wing 24 of the ()) toward the cover 30, and the lower wing 26 to the lower wing of the beam 70 is fitted.

In this way, the clamp 20 is inserted in a state in which the cover 30 and the beam 70 are wrapped, and then the bolt 50 is fitted to the nut part 24c formed on the upper wing 24 of the clamp 20. The cover 30 is fixed to the beam 70. At this time, if the bolt 50 is continuously tightened in order to fix the cover 30 to the beam 70 more stably, the bolt 50 moves downward with respect to the upper wing 24 and the end thereof is covered with the cover 30. ) And the upper wing 24 is moved upward along the bolt 50 as opposed to the movement of the bolt 50, as a result of the lower wing formed bent at a right angle to the vertical neck 22 4, the bottom surface of the beam 70 is compressed while moving upward according to the tightening force of the bolt 50, as shown in FIG. 4.

On the other hand, if the tightening of the bolt 50 to further secure the cover 30 without shaking and falling to the beam 70 of the cable tray 10, the vertical neck ( The upper wing 24 formed in the 22 is continuously moved upward, that is, the end of the bolt 50 is moved downward to press the cover 30 more strongly, the lower side formed integrally with the lower end of the vertical neck 22 The wing 26 is moved upward with respect to the bolt 50 to press the bottom of the beam 70 more strongly. At this time, even if the bolt 50 is firmly tightened, the bent portion of the upper and lower wing portions 24 and 26, that is, the boundary portion between the vertical neck 22 and the upper and lower wing portions 24 and 26 is vertical. The cover 30 and the beam 70 are squeezed with a strong elastic force, while not bending outwardly with respect to the neck 22, ie, being unfolded without bending against the vertical neck 22. 2 outwardly reinforcing projection pieces 24a and 24b, respectively, which protrude and shape by punching the boundary portions of the upper and lower wing portions 24 and 26 and the vertical neck 22 as shown in FIGS. By the tensioning action of the boundary portion is not extended by the 26a) (26b), the cover 30 and the beam 70 is compressed by a strong elastic force is fixed. In addition, the vertical neck 22 also maintains the upper and lower wing portions 24 and 26 bent by the outwardly reinforcing protrusion pieces 24a, 24b and 26a and 26b, as a result. The force to be outwardly is transmitted toward the vertical neck 22 having a constant length and width, so that the central portion of the vertical neck 22 is forced to be curved inward. At this time, as shown in Figs. 2 to 4 on the outer surface of the vertical neck 22, the inwardly reinforcing protrusion piece 22a having a predetermined length and width protruded outward by punching the inner surface has a tension action, As the 22 is not bent inwardly, the cover 30 and the beam 70 are compressed and fixed with a strong elastic force.

On the other hand, as a comparative example, the conventional technique, that is, the tighter the bolt to fix the cover, the more the boundary between the vertical neck of the clamp and the upper and lower wing portions is bent outwards, and the vertical neck is bent inward, resulting in the beam of the cable tray. Unlike the unstable fixing force between the cover and the cover, which may cause the cover to shake or the cover to fall from the beam, the present invention is intended to allow both wings to be bent vertically when the bolt is tightened to secure the cover to the beam of the cable tray. It can be seen that the two outwardly reinforcing protrusions prevent tension from being stretched vertically along the thread of the bolt while the inward reinforcement protrusions act as a tension function to prevent bending.

In this result, according to the present invention, the cover is fixed to the cable tray in which the cable is wired and installed, without any shaking and falling, so as to securely fix it. It is convenient and has the advantage of significantly shortening the fastening time.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended utility model registration claims of the present invention.

According to the clamp for fixing the cover of the cable tray according to the present invention evident from the above description, when the cover for protecting the cable from rain or foreign matters is fastened by using the clamp to the beam of the cable tray, it is elastically fastened, The cover is stably fixed to the cable tray without shaking and dropping, and both wings and vertical necks are not bent when the bolt is tightened, thereby greatly reducing the convenience and fastening time of the work.
