Problems solved by technology

[0002] The existing highway central divider guardrail does not have a semi-rigid support system (scissors support), only a steel plate of about 310mm*200m is welded horizontally at 1 / 2 of the column (flat fill surface), and its disadvantages are: When the guardrail on one side of the road is blocked by the force alone, the resistance is very limited, and its resistance is greatly affected by the tightness of the guardrail connection, the diameter and depth of the column, the compactness of the fill in the middle zone, and the horizontal steel plate

Embodiment 1

[0019] Such as figure 1 As shown, a road guardrail, the road guardrail is provided with a semi-rigid support system for the road central divider guardrail, and the system includes two columns 1, and the two columns 1 are symmetrically provided with four hoops 2 up and down, left and right, The hoop 2 is connected to the adjustable long screw rod 4 through the connecting pin 3, the adjustable long screw rod 4 constitutes a support frame through two cross adjustment plates 5, and the adjustable long screw rod 4 passes through the positioning nut 8 and the lock nut 7 is fixed on the adjusting plate 5.

[0020] Two adjustment grooves 6 are arranged in the middle of the cross adjustment plate 5 , and the two cross adjustment plates 5 are fixed by positioning bolts 9 .

[0021] The semi-rigid support system for the guardrail of the highway central divider adopts a straddling layout along the driving direction.

[0022] The diameter of the adjustable screw 4 is 16mm-24mm.

Abstract

The invention relates to the field of highway safety facilities, in particular to a highway fence. The highway fence is also called a highway center separator fence semi-rigid supporting system and is a cross-shaped semi-rigid supporting system which comprises a left stand column, a right stand column, four hoops distributed longitudinally, transversely and symmetrically, four long adjustable threaded rods, two cross adjusting plates manufactured by profile steel, a positioning pin, a connecting pin, a positioning nut, a locking nut and the like, so that a left fence and a right fence which are not originally and mutually connected are in semi-rigid connection. The effective supporting strength of a highway center separator fence can be improved, the influence of bumping of a vehicle on the safety of the road side, safety of personnel in the vehicle and safe vehicle running of the other lane is protected as much as possible, and the security threat is reduced.

Description

technical field [0001] The invention relates to the field of road safety facilities, in particular to a road guardrail. Background technique [0002] The existing highway central divider guardrail does not have a semi-rigid support system (scissors support), only a steel plate of about 310mm*200m is welded horizontally at 1 / 2 of the column (flat fill surface), and its disadvantages are: When it is blocked by the force of the guardrail on one side of the road alone, the resistance is very limited, and its resistance is greatly affected by the tightness of the guardrail connection, the diameter and depth of the column, the compactness of the fill in the middle zone, and the transverse steel plate. Contents of the invention [0003] In order to solve the above problems, the present invention provides a road guardrail, [0004] A road guardrail, a cross-connected semi-rigid support system is set along the left and right columns of the guardrail in the middle of the highway, a...
