Abstract
The utility model relates to a variable wave form guardrail. The problem of present guardrail establish the sleeve and improve guardrail plate height degree with adding through lifting the stand, cause the road bed not hard up, the stand receives the damage is solved. The guardrail includes the stand, connects the guardrail board on the stand through preventing block around the stand respectively vertical division have microscler groove, be equipped with fixing bolt on the stand, fixing bolt crossed two microscler grooves, the fixing bolt front end is fixed on preventing block, has penetrated the lifting screw at the stand top, the lifting screw passes through lifting adjusting mechanism swing joint on the stand, the lifting screw lower extreme is equipped with the barb, the barb catches hold of with a hook on fixing bolt. The utility model has the advantages that need not to lift the stand and establish the sleeve with adding, on the basis of original wave form guardrail, need not destroy original road bed and not plus under the mode such as sleeve, lead to and adjust the lifting screw, drive fixing bolt to reach the purpose of adjusting guardrail plate height degree, simple structure, convenient operation.
Description
Technical field
The utility model relates to a kind of guardrail, particularly relates to a kind of type variable corrugated guardrail of flexible modulation guardrail board height.
Background technology
At present because of the impact of cover project in engineering for pavement maintenance, original corrugated guardrail height is not enough, and the old guardrail of main employing lifts and adds sleeve two kinds of modes.But also there is certain defect in these two kinds of modes.
Guardrail lifts exists following two problems:
1) former trackside and median barrier column are driving into type or bury people's formula steel pipe post, if lifted by column, then foundation of road bed may be caused to loosen, and particularly may cause loosening of semi-rigid base course, cause pavement strength not enough.
2) pre-buried many communication pipes inside general median barrier, arbitrarily lift column, are easily scratched by pre-buried pipeline, cause damage, thus cause the interruption of road telecommunication, have influence on the normal operation of highway to communications optical cable (cable).
Add sleeve and there is following two problems:
1) sleeve and original fence upright carry out mechanics connection only by bolt, when vehicle collision, this point will become stressed most weak spot, therefore, whether the program can meet < freeway guardrail security performance evaluation standard) requirement of (JTG/TF83-01-2004), experimental study of still needing is determined.
2) add sleeve need again to punch installation, punching may damage column, causes waste.
Summary of the invention
The utility model mainly solves divider current and improves guardrail board height by lifting column and adding sleeve, roadbed is caused to loosen, the problem that column is damaged, provides a kind of without the need to lifting column and adding sleeve, the type variable corrugated guardrail of energy flexible modulation guardrail board height.
The utility model solves the technical scheme that its technical problem adopts: a kind of type variable corrugated guardrail, comprise column, the guardrail board on column is connected to by obstruction block, vertically elongate slots is had respectively before and after described column, column is provided with set bolt, set bolt passes across two elongate slots, set bolt front end is fixed on obstruction block, column top has penetrated lifting screw, lifting screw is movably connected on column by lifting regulating mechanism, lifting screw lower end is provided with barb, and barb is hooked on set bolt.The utility model can flexible modulation guardrail board to the height on ground, solving conventional method needs to lift column or again punch on column, and foundation of road bed can be caused to loosen, and column is damaged, wasting problem.The utility model, on the basis of original corrugated guardrail, need not destroy existing roadbed and not under the mode such as additional sleeve, set up adjustable guardrail board terrain clearance mechanism.As long as regulate lifting screw height during operation, lifting screw drives set bolt to be elevated in elongate slots, and obstruction block is elevated with set bolt, thus reaches the object regulating guardrail board height.
As a kind of preferred version of such scheme, described lifting regulating mechanism comprises pad, hold-down nut and adjusting nut, and described pad, hold-down nut and adjusting nut are enclosed within lifting screw successively and expose on one section of column end face.Lifting screw and column end face fix by pad, hold-down nut, regulate lifting screw to be elevated by rotating adjusting nut.
As a kind of preferred version of such scheme, described obstruction block is the square tubular of upper and lower opening, and the one side that obstruction block and column contact is the cambered surface of the indent matched with column side, fixes before obstruction block with guardrail board.The cambered surface of obstruction block matches with column side, can tightly paste firm column during installation, and obstruction block upper and lower opening convenient operation person stretches in obstruction block and carries out nut fixing operation.
As a kind of preferred version of such scheme, have fixing hole in the middle of described cambered surface, described set bolt front end is passed fixing hole and is fixed by obstruction block by nut.Obstruction block cambered surface coordinates with leg surface, is then just fixed by obstruction block by set bolt.
The utility model has the advantages that: without the need to lifting column and adding sleeve, on the basis of original corrugated guardrail, existing roadbed need not be destroyed and not under the mode such as additional sleeve, logical adjustment lifting screw, drive set bolt, thus reaching the object regulating guardrail board height, structure is simple, easy to operate.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
A kind of type variable corrugated guardrail of the present embodiment, as shown in Figure 1, comprise column 1, column is provided with obstruction block 2, obstruction block is connected with guardrail board 3, before and after on column, vertically have elongate slots 10 respectively, column is provided with set bolt 8, set bolt passes across two elongate slots, and the nut of set bolt is stuck in column elongate slots below, and set bolt front end is through to penetrate after elongate slots on obstruction block and to be fixed on obstruction block.
Column top has penetrated lifting bolt 5, and lifting screw is movably connected on column by lifting regulating mechanism, and as shown in Figure 2, lifting screw lower end is provided with barb 6, and barb is hooked on set bolt.
As shown in Figure 1, obstruction block 2 is the square tubular of upper and lower opening, and the one side that obstruction block and column contact is the cambered surface of the indent matched with column side, fixes before obstruction block with guardrail board.Have fixing hole in the middle of cambered surface, then obstruction block is fixed on column by nut through fixing hole by the front end of set bolt.
Lifting regulating mechanism comprises pad 7, hold-down nut 8 and adjusting nut 9, and pad, hold-down nut and adjusting nut are enclosed within lifting screw 5 successively and expose on one section of column end face.
