Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a central isolation belt guardrail. Background Art

[0002] As traffic continues to grow, road safety issues are becoming increasingly serious. As a key component of road infrastructure, central median barriers not only separate oncoming traffic and reduce the likelihood of traffic accidents, but also, to a certain extent, protect the safety of vehicles and pedestrians in accidents.

[0003] The height of traditional median guardrails is usually fixed and cannot be flexibly adjusted according to the specific conditions of the road and changes in traffic flow. For example, when a large number of large trucks and buses pass through the road section, the guardrails may not provide adequate protection. In addition, pedestrians can easily cross the central median, and the overall safety is not high. Moreover, the median guardrails are mostly protected by multiple vertical bars, and the anti-collision effect is poor. When a vehicle hits the guardrail, the impact force is often concentrated on the vertical bar that is hit, which can easily cause the vertical bar to deform or be damaged, and cannot effectively block the vehicle, increasing the risk of the vehicle rushing out of the guardrail and colliding with other vehicles or obstacles. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] Combined with attachment Figure 1 and attached Figure 2 A central isolation belt guardrail includes at least one counterweight base 1, the top of each counterweight base 1 is provided with a column 2, an extension column 3 is inserted in the column 2, and the top of each extension column 3 is provided with a fixedly connected top seat 4, and multiple horizontal connecting rods 5 that are easy to disassemble and assemble are provided between the columns 2 and the extension columns 3, and multiple vertical connecting rods 6 that are evenly distributed are provided between the horizontal connecting rods 5.

[0025] Through the above structure, the entire guardrail can be formed by using the horizontal connecting rod 5, the vertical connecting rod 6, the column 2 and the extension column 3. The structure is simple and easy to implement.

[0026] Combined with attachment Figure 4 and attached Figure 5 A locking structure is provided between the extension column 3 and the column 2. The locking structure includes a stud 9 which is inserted into the column 2 and passes through the bottom end of the extension column 3. Both ends of the stud 9 are provided with threaded locking nuts 10. The thread directions of the locking nuts 10 on both sides are opposite. Both ends of the extension column 3 are provided with through holes 13 for use with the stud 9.

[0027] Through the above structure, the extension column 3 is stretched outward, and then the stud 9 is passed through the column 2 and the through hole 13 in turn, and the column 2 and the extension column 3 are locked and fixed using the locking nuts 10 on both sides. The overall structure is easy to adjust and the guard height can be easily increased. It can not only improve the guard effect, but also prevent pedestrians from climbing at will, and the overall safety is high.

[0028] Combined with attachment Figure 5Both sides of the transverse connecting rod 5 are provided with fixed plates 11, and the four corners of the fixed plate 11 are fixed and locked together with the two sides of the column 2 and the extension column 3 through fastening bolts 12. Both sides of the column 2 and the extension column 3 are provided with multiple threaded holes 14 used for fastening bolts 12.

[0029] Through the above structure, both sides of the transverse connecting rod 5 can be directly fixed to the column 2 or the extension column 3 through the fixing plate 11 and the fastening bolts 12, which has a simple structure and is convenient for disassembly and assembly.

[0030] Example 2

[0031] Combined with attachment Figure 3 Both sides of the vertical connecting rod 6 are provided with a fixedly connected corrugated anti-collision plate 7, and the corrugated anti-collision plate 7 is provided with at least one reflective strip 8, and the reflective strip 8 is glued to the corrugated anti-collision plate 7.

[0032] Through the above structure, the corrugated anti-collision plate 7 can produce a certain amount of plastic deformation when a vehicle collides, thereby effectively absorbing the impact energy, reducing the impact force of the vehicle, and greatly reducing the deformation or damage to the guardrail. In addition, the reflective strip 8 can improve visibility and warning effects at night and in severe weather conditions.

[0033] Combined with attachment Figure 3 The upright column 2, extension column 3, transverse connecting rod 5, vertical connecting rod 6 and corrugated anti-collision plate 7 are all made of steel, with high overall strength and corrosion resistance.

[0034] When the utility model is implemented:

[0035] First, place the columns 2 and the counterweight base 1 on both sides directly on the ground. The counterweight base 1 is fixed directly to the ground through expansion screws. The two sides of the transverse connecting rod 5 can be directly fixed to the column 2 through the fixing plate 11 and the fastening bolts 12. Since there are threaded holes 14 on both sides of the column 2, multiple guardrails can be connected and assembled into one, with a simple structure and easy disassembly and assembly.

[0036] When the road needs to pass a large number of large trucks, buses or pedestrians climbing the guardrail multiple times, unscrew the studs 9 and locking nuts 10 on the column 2, and stretch the extension column 3 outward, then pass the studs 9 through the column 2 and the through hole 13 in turn, and use the locking nuts 10 on both sides to lock and fix the column 2 and the extension column 3. The overall adjustment is convenient and the height of the barrier can be increased conveniently, which not only improves the barrier effect, but also prevents pedestrians from climbing at will, and the overall safety is high.

[0037] The corrugated anti-collision plate 7 can produce a certain amount of plastic deformation when a vehicle collides, thereby effectively absorbing the impact energy, reducing the impact force of the vehicle, and greatly reducing the deformation or damage to the guardrail. In addition, the reflective strip 8 can improve visibility and warning effects at night and in severe weather conditions.
