There is an advantage that it can significantly reduce the installation man-hours of safety facilities.

In addition, the first and second sliding fasteners 133a and 133c are provided on the extension support cover 133 of the extension support module 130 to provide the first sliding connection part 133a or the second sliding connection part 133c. In the safety facility or the fixing bracket 210 of the sign 200 can be fixed by adjusting the height only by a simple bolting operation without separate welding or bending work.

In other words, in the case of a conventional general guardrail, in order to install a sign, a separate post is made and buried, or the sign is combined with the post by banding, so that the sign is inverted by an external force or rotated around the post, so that the driver As situations that cannot be properly recognized occur very frequently, there is a problem in that the driver cannot properly recognize the road conditions while driving, and thus the driver is placed in a very dangerous situation.

On the other hand, the expandable guard rail 100 capable of installing a safety facility according to an embodiment of the present invention has a first sliding connection part 133a or a second sliding connection part without a bend or buried construction by making a separate post. A simple bolting operation on (133c) can be installed by adjusting the height of the fixing bracket 210 of the safety facility or the sign 200.

Therefore, not only can the installation time and cost of the safety facility or the sign 200 be significantly reduced, but also the sign 200 that can inform the driver of a very important road situation during driving may fall or the post 110 The advantage is that the driver does not properly grasp the road situation because it is rotated around the center.
