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

The safety railing provided with the fixing means according to the present invention comprises a vertical pipe vertically installed at a predetermined distance from the safety railing and a horizontal pipe and a clamp coupled to the vertical rail.

However, there is a technical feature different from the conventional technology in the combination of the horizontal pipe and the clamp.

First, as for the clamp,

2 is a perspective view showing a clamp according to a preferred embodiment of the present invention.

As shown in FIG. 2, the clamp 100 is formed with a fixing groove 110 having an open upper portion to which a fastening portion of a horizontal pipe is coupled. An upper portion of the fixing groove 110 and a lower wide inlet groove 122 Is extended.

The fixing groove and the inlet groove will be described in more detail.

4 is a perspective view illustrating a horizontal pipe according to a preferred embodiment of the present invention.

As shown in FIG. 4, the horizontal pipe is in the form of a long pipe, and a fastening portion 12 having a rectangular cross section at its end is formed. The fastening part 12 is engaged with the vertical pipe through the inflow groove and the fixing groove previously described with reference to FIG.

First, when passing through the narrow upper inlet groove, a direction in which the width of the fastening portion 12 is narrow is used, and the horizontal pipe is rotated in the direction of 90 degrees in the inflow groove having a wide width to prevent the horizontal pipe from being separated. And is coupled to the fixing groove through the wide surface and the interference fit.

This structure allows the horizontal pipe to remain coupled with the vertical pipe.

The horizontal pipe 10 is provided with safety protrusions 14 and 16 protruding from left and right sides of the coupling part 12 so as to be stably fixed to the fixing groove.

In this way, when the horizontal pipe is coupled with the clamp of the vertical pipe, the horizontal pipe is more stably fixed using the fixing means.

The fixing means shown in FIG. 2 includes a fixing pin 130 fixed to one side of the clamp, a supporting spring 130 having one side rotatably coupled to the fixing pin 130 and contacting the upper surface of the horizontal pipe fastening portion And a support pin 140 installed on the opposite side of the fixing pin 130 and fixing the other side of the supporting spring.

First, the support spring 150 uses a leaf spring structure. When the spring is fixed using the support pin 140 in a state where the horizontal pipe is coupled to the fixing groove, the support spring 150 elastically supports the upper surface of the coupling part.

FIG. 3 is a perspective view illustrating a combined state of a clamp and a horizontal pipe according to a preferred embodiment of the present invention. Referring to FIG.

3, when the fastening portion of the horizontal pipe 10 is engaged with the fastening groove and the support spring 150 is rotated and fixed to the lower portion of the support pin 140, the lower side of the support spring is fastened to the upper surface of the fastening portion And is elastically supported vertically downward while being in contact.

In order for the support spring 140 to be moved downward, the engagement with the fixing pin 130 is maintained in a state in which the engagement with the support pin 140 can be slightly moved forward and backward as well as in the rotation direction. By using such fixing means, the clamping force of the clamp due to the repeated cyclic load and wind vibration can be prevented in advance.

These securing means should be installed on both sides of the clamp so that both horizontal pipes can be fixed together.

Referring to another embodiment related to the fixing means,
