Description

{Extruding safety guardrail for level adjustment}

The present invention relates to an extrusion type safety rail which is installed in a barrier wall, and in particular, it is possible to adjust the level of height through the level base without changing the leveling post, The present invention relates to an extrusion type safety rail which is low in construction cost.

In general, safety rails installed on one side of bridges and roads are safety facilities that prevent damage caused by fall of roads when the vehicle is running, thereby preventing damage to persons and property caused by falling accidents. Therefore, a railway stake is installed on a barrier or a concrete on one side of a bridge and a road, and a rail with a guard rail is installed on the railway stall to prevent the vehicle from falling out of the road.

In this case, horizontal leveling should be done when the balustrade is installed on the top of the barrier. In the case of the barrier wall, the roughness of the surface becomes uneven after the construction because it is made by the casting of the concrete, so that it is difficult to install the railway support at the correct horizontal level. In this case, the position of the guardrail to be installed on the railing support is changed and the workability is lowered.

In addition, conventionally used railing supports are made of castings and have a drawback that their weight is heavy, mass production is difficult, precision is low, and post-work is accompanied, resulting in very low productivity.

As a background of the present invention to solve this problem, Korean Patent Registration No. 10-0557227 discloses an extrudable type railing post and a reinforcing post thereof. This is to prevent the vehicle from falling out of the road due to breakage or deformation of the post when the vehicle collides with the railing by greatly improving the strength of the railing post which provides the supporting force of the railing. And the outer surface of the reinforcing post is provided with outer surface irregularities which are fitted to the inner surface of the railing post.

However, the above background art does not disclose a method for accurately setting the level of a railing post on a railing post, and there is no technical means for adjusting the level of a railing post.

The first level base 20 is supported through a point on the upper surface of the barrier 10 so that the leveling of the barrier post 30 is possible without being affected by the upper surface roughness of the barrier 10. Here, 'point' means a smaller surface contact than the bottom surface of the linear or paraplegic strut 30.

Further, the elevation level of the railing support 30 can be adjusted without replacing the railing support 30 according to the selection of the height of the first level base 20.

3 and 4, a plurality of anchor bolts 12 are installed on the upper surface of the barrier wall 10 so as to protrude upward for each portion where the railing support 30 is installed at regular intervals. The anchor bolts 12 may be provided in a plurality of positions in one place.

A plurality of points P1, P2 and P3 are supported on the upper surface of the barrier wall 10 by a tightening force of the nuts 13 fastened to the anchor bolts 12 at respective positions where the railing supports 30 are installed, A level base 20 is installed.

The first level base 20 includes a column support portion 21 for supporting the bottom surface of the extruded railing support 30 and a nut for fastening the anchor bolt 12 downward on the upper surface of the column support portion 21 A nut receiving portion 22 having an insertion hole 22b of an anchor bolt 12 formed on a bottom surface of a nut fastening groove 22a formed to be positioned at a lower end of the nut holding groove 22a, A plurality of branch legs 23 protruding and extending further downward by a predetermined amount G than the lower surface of the nut receiving portion 22 and a plurality of branch leg portions 23 extending upward from both side portions of the landholder receiving portion 21, And a base joint portion (24, 25) for fastening the bolt (14) to the bolt (30).

The extruded railing support 30 is manufactured by aluminum extrusion in this embodiment, and its lower end is coupled to the first level base 20 through bolts 14 and nuts 15. It is preferable that the extruded railing support strut 30 is formed in a shape having a plurality of hollows in consideration of strength, light weight, and manufacturing cost.

A hollow guardrail (40) is provided on the upper end of the extruded railing support (30). The hollow guard rails 40 are fixedly mounted on the side of the extruded railing support 30 via fastening means (bolts and nuts) not shown.

In the safety railing constructed as described above, the first level base 20 is fixed to the upper surface of the barrier 10 by using the anchor bolts 12 and the nuts 13.

At this time, when the tightening force of the nut 13 is generated, the three pointing legs 23 act as points on the upper surface of the barrier wall 10, so that the horizontal level of the first level base 20 is achieved. That is, even if there is a slight rugged portion on the upper surface of the barrier 10, the first level base 20 is stably installed without losing the horizontal balance.

Then, a railing support 30 is installed on the first level base 20. The bottom of the railing support 30 is brought into close contact with the upper surface of the column support portion 21 of the first level base 20 and the base joints 24 and 25 are fastened to each other through the bolts 14 and the nuts 15 To the railing support (30).

At this time, since the first level base 20 has a horizontal level, the parapet 30 is installed in the same horizontal posture.

Then, the hollow guard rail 40 is fixed to the railing support 30.

The extrusion safety rail according to the first embodiment of the present invention is constructed such that the first level base 20 and the railing support 30 are made of extruded material and then cut by a desired length to reduce the production cost. In addition, since the first level base 20 has a horizontal level, the guard rail 40 installed on the side of the railing support 30 as well as the railing support 30 can be accurately aligned.
