Description

[Detailed Description of the Invention] The present invention relates to a guardrail adjustment post that raises and supports the guardrail in response to the raised road surface due to road repair.

Conventionally, such adjustment posts have a hollow cylindrical shape that is crowned on an existing column, with a hole for installing a guardrail formed through the upper part, and an elongated hole extending vertically through the lower part. A bolt for fixing to the column was inserted through the column, and then tightened and fixed with a nut at a predetermined height.

However, since such adjustment posts are fixed to the pillars at predetermined positions in the long holes simply by the tightening action of the Pol I bolts and nuts, the bolts may loosen even slightly due to vibrations, contact, etc. when a vehicle passes by. The adjustment post has the drawback of sliding down, and the adjustment post must be kept raised at the desired height during the raising operation, which is extremely difficult.

In view of the above-mentioned drawbacks, the present invention has been developed by forming locking grooves on both sides of a vertically extending elongated hole, which is provided to vertically adjustably fix the adjustment post to a column, and forming locking grooves in stages, alternating left and right. An embodiment of the present invention will be described below based on the drawings, with the aim of solving the above-mentioned drawbacks by making it possible to insert and support bolts. 1 shows the main body of a guardrail adjustment post that is mounted on an existing support post 2; It is made of metal and has a hollow cylindrical shape, and a cap body 3 is fixed to the upper end surface.

Elongated holes 5, 5' extending vertically over appropriate lengths are provided through the opposing wall surfaces 4, 4' at the bottom of the main body 1, respectively, and elongated holes 5 are provided on both sides of the elongated holes 5, 5'. , 5' are formed in a stepwise manner alternately on the left and right sides.

The groove widths of the elongated holes 5, 5' and the locking grooves 6, 6' are set to be slightly larger than the diameter of the bolt 7 for fixing the main body 1 to the support column 2. .

Note that 8, 8', . . . are ribs that are not recessed inwardly on both sides of the elongated hole 5 in the wall surface 4.

Furthermore, the locking groove 6 is formed in the wall surfaces 4, 4' at the upper part of the main body 1.
, 6'..., elongated holes 9, 9 extending left and right in correspondence with
' are provided through each.

The support column 2 has a hollow cylindrical shape with a predetermined standard outer diameter, as shown in FIG.
The base of the guardrail 11 is fixedly supported by bolts 13 through the mounting holes 12 using the mounting holes 10 and 10'.

Next, to explain how to use the guardrail adjustment post I- according to the present invention, first, the guardrail 11 fixed to the support column 2 is removed.

Next, the main body 1 is mounted on the outer periphery of the support 2, and the bolts 7 are inserted into the long holes 5, 5' at the bottom of the main body 1 and into the mounting holes 10 of the support 2.
．． 10', and then lift the main body 1 along the elongated holes 5, 5' to the desired raised position and rotate it to either the left or right and lock the locking grooves 5//, 6/ in that position.
The main body 1 is fixed to the support 2 by inserting a bolt 7 into the inside and screwing a nut 14 into the tip of the bolt 7.

Next, the guardrail 11 removed from the support 2 is brought into contact with the upper part of the main body 1, and the mounting hole 12 of the guardrail 11 is
and insert the bolts 15 into the long holes 9, 9' in the upper part of the main body 1,
A nut 16 is screwed into the tip of the bolt 15 to fix the guardrail 11 to the main body 1.

In the figure, 17, 17', . . . are washers. Next, if it becomes necessary to raise the guardrail 11 again, loosen the nuts 16 that fixed the guardrail 11 and the nuts 14 that fixed the main body 1 to the support 2, and then rotate the main body 1 and lock it. Remove the bolts 7 from the grooves 6'', 6'', lift the main body 1 along the elongated hole 5.5' to the desired height, and remove the locking grooves 6ttt, 6/
// After inserting the bolt 7 inside, loosen it again) 14.1
It can be easily adjusted by tightening 6.

It goes without saying that the main body 1 can be used not only by being fixed to the existing pillar 2, but also by being fixed to the pillar 2 in the lowest position in advance when constructing a new guardrail.

In short, the present invention has long holes 5, 5' extending vertically in the opposing wall surfaces 4, 4' at the bottom of the main body 1 in a hollow cylindrical adjustment post that is crowned by a post on which a guardrail is attached.
are provided through the elongated holes 5, 5' on both sides of the elongated holes 5, 5'.
Since the locking grooves 6, 6', . . . communicating with the 5//, 5
By fitting inside //, the vertical movement of the main body 1 is regulated, so that the main body 1 does not slide down due to vibration or contact when a vehicle passes, and the guardrail 11 can be reliably held in a fixed position. During the tightening operation of the nut 14 against the bolt 7, the bolt 7 is held in the grooves 6, 6'...
・By fitting inside, there is no need to maintain the main body 1 in a lifted state, and the raising operation can be performed extremely easily.Furthermore, the locking grooves 6, 6'... are arranged in stages alternately on the left and right. Since the bolts 7 can be smoothly inserted into the locking grooves 6///, 6/// when raising the body 1 again, the upper wall surface 4,
4' has elongated holes 9 and 9' extending left and right corresponding to the locking grooves 6 and 6', so that the elongated holes 9 and
When inserting the fixing bolt 15 of the guardrail 11 into the elongated hole 9.9', the bolt 15 has a large opening area.
The tip of the body 1 can be easily penetrated, thereby greatly improving the work efficiency.Furthermore, the body 1 can be rotated by a predetermined width simply by loosening the nut 16 screwed into the bolt 15, so there is no need to remove the guardrail 11 when raising the height. Its practical effects are enormous.
