Problems solved by technology

[0003] The anti-collision guardrail installed on the road can effectively reduce or even avoid the damage to the vehicle itself, personnel and road facilities caused by the accidental impact caused by the shuttle on the road. At present, most of the anti-collision guardrails on the road are made of steel structure. , such as guardrails formed by round steel pipes, square steel pipes or profiled steel plates, cannot absorb external forces, reduce impacts, and cannot play a supporting role, and will fracture and deform, causing injuries to personnel and damage to property

Embodiment 1

[0029] like figure 1 As shown, a railing for a buffer guardrail includes a railing body 1, two ends of the railing body 1 are provided with an end connecting sleeve 2, and the outer end of the end connecting sleeve 2 is provided with a threaded connection unit. The threaded connection unit is to connect the internal threaded hole 3, such as figure 2 As shown, the threaded connection unit can also be a connection stud 6 with external threads. The other ends of the two end connecting sleeves 2 are connected by reinforcing ribs 4 . The railing body 1 is made of waste rubber. The waste rubber can be prepared by putting the waste rubber into the crusher in a formula amount, crushing it into waste rubber particles with a diameter of 1-4mm, and then mixing with the curing agent and anti-aging agent, and then curing. production. This solves the problem of recycling waste rubber, especially waste tires; the cross section of the railing body 1 can be circular, square or hexagonal. ...

Embodiment 2

[0032] like image 3 As shown, on the basis of the above-mentioned embodiment 1, a middle connecting sleeve 5 is provided between the two end connecting sleeves 2 , and the two end connecting sleeves 2 and the middle connecting sleeve 5 are connected by reinforcing ribs 4 . One end of the middle connecting sleeve 5 is provided with a threaded connection unit, and the axis of the threaded connection unit is perpendicular to the centerline of the railing body 1 . The number of the middle connecting sleeves 5 is 2-15. The threaded connection unit at the outer end of the end connecting sleeve 2 and the threaded connecting unit at one end of the middle connecting sleeve 5 are both connecting internal threaded holes 3 . like Figure 4 As shown, the threaded connection unit at the outer end of the end connection sleeve 2 and the threaded connection unit at one end of the middle connection sleeve 5 are connection studs 6 .

[0033] The railing described in Embodiment 2 can be used ...

Embodiment 3

[0035] like Figure 5 As shown, on the basis of the above-mentioned embodiment 2, both ends of the middle connecting sleeve 5 are provided with threaded connection units, and the threaded connection units are connecting internal threaded holes 3 . like Image 6 As shown, the threaded connection unit can also be a connection stud 6 with external threads. At this time, this embodiment can only be used as an intermediate column, and both sides of the column can be connected with the upper beam and the lower beam.

Abstract

The invention provides a handrail of a buffer guardrail. The handrail comprises a handrail body (1), end connecting sleeves (2) are arranged at the two ends of the handrail body (1), threaded connecting units are arranged at the ends of the outer ends of the end connecting sleeves (2), and the other ends of the two end connecting sleeves (2) are connected through reinforcing ribs (4). The buffer guardrail manufactured through the method is simple in structure, reasonable in design, convenient to disassemble and assemble, high in deformation capacity, capable of being repeatedly used, good in using effect and longer in service life.

Description

technical field [0001] The invention relates to a buffer guardrail, in particular to a railing of an improved buffer guardrail. Background technique [0002] Existing guardrails usually include guardrails, support poles, guardrail bases and guardrail jacks. There is only one row of fixed guardrails. [0003] The anti-collision guardrail installed on the road can effectively reduce or even avoid the damage to the vehicle itself, personnel and road facilities caused by the accidental impact caused by the shuttle on the road. At present, most of the anti-collision guardrails on the road are made of steel structure. , such as guardrails formed by round steel pipes, square steel pipes or profiled steel plates, cannot absorb external forces, reduce impacts, and cannot play a supporting role, and will fracture and deform, causing injuries to personnel and damage to property. Therefore, it is necessary to design a highway anti-collision guardrail with simple structure, reasonable d...
