Description

Side rail and rung connection structure of cable tray {STRUCTURE FOR FIXING SIDE RAIL AND RUNG OF CABLE-TRAY}

The present invention relates to a connection structure of the side rail and the rung of the cable tray, and more particularly, a cube-shaped insert having a tapped hole is inserted into the end of the rung, and a caulking protrusion and an end of the rung are fixed to fix the inserted insert. It relates to the connection structure of the side rail and the rung of the cable tray in which the bent portion is formed.

Korean Patent No. 10-941862 (registered on February 3, 2010) introduces a method of fixing a rail and a rung of a cable tray.

The method of fixing the connection between the rail and the rung of the cable tray includes inserting brackets at both ends of the rung, and recessing the bottom of one end of the bracket having a fastening member inserted into the rung and including a fastening hole therein. A process of forming, a process of recessing as much as the recessed portion of the bracket when both ends of the rung is recessed while the bracket is inserted in the rung, and a square hole at both ends of the rung to which the bracket is coupled as described above. The perforated rails are in contact with each other so as to match the fastening holes of the brackets with the holes of the rails; The process of contracting the fixing portion to form a wrinkle by the pressing of the head of the support portion by pulling the support of the, and the outer diameter of the fixing portion is expanded when the fixing portion is contracted When the outer diameter of the fixing part is expanded, the fixing part is deformed as the shape of the hole in the hole of the rail to seal the hole, and the outer diameter of the fixing part is expanded to close the fixing groove of the fastening hole. The rail and the rung are firmly fastened by the action of the rivet in the fastening hole of the bracket fixed to the rung.

However, the fastening and fixing method of the rail and the rung of the conventional cable tray as described above has a disadvantage in that the number of parts is large and the structure and connection work are complicated.

Accordingly, an object of the present invention is to insert a hexagonal insert having a tab hole at the end of the rung, and a caulking protrusion and a bent portion are formed at the end of the rung to fix the inserted insert, so that the bolt is connected through the bolt hole of the side rail. By fastening to the tapped hole of the insert, the number of parts can be reduced and the cost of the product can be reduced, and the structure of the cable tray side rail and the rung is provided to simplify the structure and connection work.

The connection structure of the side rail and the rung of the cable tray according to the present invention for achieving the above object is that the end of the rung is connected to the side rail so that a plurality of rungs are arranged at regular intervals between the two side rails facing each other. In the cable tray, a cube-shaped insert having a tapped hole is inserted at the end of the rung, and a caulking protrusion and an end bent part are formed at the end of the rung to fix the inserted insert, and the bolt is inserted through the bolt hole of the side rail. It is characterized in that it is fastened to the tab hole.

As a result, the connection structure of the side rail and the rung of the cable tray according to the present invention is that the insert is not separated from the rung by external force, and the rung is formed of a square pipe, so that the operator does not deform when stepping on the rung, Since it is molded from a steel material, the clamping force between the insert and the bolt is strong, the number of parts can be reduced, and the cost of the product can be lowered.

Figure 2 is a cross-sectional view taken along line AA of Figure 1 showing a connection structure of the side rail and the rung of the cable tray according to the present invention
Figure 3 is a side view showing the end of the rung inserted insert

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3, in the cable tray according to the present invention, a plurality of rungs 20 are disposed at regular intervals between two side rails 10 facing each other, so that the ends of the rungs 20 are side rails ( 10) respectively.

In the cable tray as described above, the connection structure of the side rail and the rung of the cable tray according to the present invention is inserted into the insert 30 having a hexahedral shape, the tab hole 31 is formed at the end of the rung 20, A caulking protrusion 21 and an end bent portion 23 are formed at the end of the rung 20 to fix the insert 30, and the bolt 40 is inserted through the bolt hole 11 of the side rail 10. It is fastened to the tab hole 31 of (30).

The side rail 10 is formed in a "c" shape, the lower horizontal portion 12 is to support the end of the rung (20).

The rung 20 is made of a square pipe, and inserts the insert 30 of the steel material at the end, and at the same time by molding the coating protrusion 21 and the bent portion 23 by a press working method to fix the insert, The caulking protrusion 21 may be molded, the insert 30 may be inserted into an end portion of the hollow portion 25, and then the bent portion 23 may be bent to fix the insert 30.

In the connection structure of the side rail and the rung of the cable tray according to the present invention configured as described above, the insert 30 is inserted into the hollow portion 25 end of the rung 20 to the caulking protrusion 21 and the bent portion 23. It is fixed by the insert, the insert 30 is not easily released from the rung 20 by the external force, the rung 20 is composed of a square pipe, the operator does not deform when stepping on the rung, the insert 30 is steel Molded from the material, the fastening force of the insert 30 and the bolt 40 is strong, the number of parts can be reduced to reduce the product cost, the structure is simple, there is an advantage of easy connection work.
