Technical Field

[0001] The utility model relates to the technical field of anti-collision guardrails, in particular to an anti-collision guardrail for a central isolation zone of an expressway. Background Art

[0002] Highway isolation belts are important transportation infrastructure. my country's expressways have been developed since the 1980s. They play an important role in the development of the national economy and society. Highway isolation belts are important maintenance and safety facilities for highways. However, when driving on highways at night, because there are no street lights, drivers often hit the isolation belts due to careless driving. Therefore, most isolation belts have anti-collision and warning devices.

[0003] Common isolation belts are made of steel structural materials. Due to the inherent characteristics of steel structural materials, their deformation capacity is very small and they have almost no flexibility. After being hit by a car, the anti-collision plate has no buffering effect and the front of the vehicle will be severely damaged due to the hard impact. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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] As attached Figure 1 , Attachment Figure 2 and attached Figure 4 As shown, a highway central isolation zone crash barrier includes multiple sets of support members 1 and multiple sets of crash barrier panels 3. The lower end of the support member 1 is connected to a mounting member 2. The mounting member 2 includes a mounting base 201. The mounting base 201 is penetrated by multiple sets of mounting ground plugs 202.

[0025] The support member 1 includes a support pile 101, and a plurality of mounting grooves 102 are provided on one side of the support pile 101 from top to bottom. A plurality of springs 103 are provided at the bottom of the mounting grooves 102, and a connecting plate 104 is connected between the other ends of the plurality of springs 103;

[0026] The crash barrier 3 includes an arc-shaped plate 301 , and connecting strips 302 are respectively provided at the upper and lower side edges of the arc-shaped plate 301 . Two groups of connecting strips 302 are respectively passed into the interiors of two adjacent groups of mounting grooves 102 and fixedly connected to the connecting plate 104 .

[0027] Through the above structure, multiple groups of installation plugs 202 pass through the installation base plate 201 and are fixedly inserted into the road surface, and the support member 1 is fixedly installed. The crash barrier 3 is segmented, and the length of a group of crash barrier 3 is 30-50m. The connecting strips 302 on the upper and lower sides of the crash barrier 3 are slid into the two groups of corresponding installation grooves 102 on the multiple groups of support piles 101, and the connecting strips 302 are fixedly connected to the connecting plate 104. When a vehicle hits the crash barrier 3, the impact force on the crash barrier 3 is buffered by the multiple groups of springs 103 to prevent the crash barrier 3 from causing serious collisions with the front of the vehicle. The specific structure is as follows:

[0028] Combined with attachment Figure 1 and attached Figure 2 As shown, the arc plate 301 and the connecting bar 302 are an integrally formed structure, and a plurality of threaded holes 303 are correspondingly provided on the two groups of connecting bars 302. Bolts 5 pass through the threaded holes 303, and one end of the bolt 5 is threadedly passed into the interior of the connecting plate 104. A groove 105 for the bolt 5 to pass through is provided on one side wall of the mounting groove 102.

[0029] With the above structure, after the connecting bar 302 is inserted into the installation groove 102 , the bolt 5 is passed through the groove 105 and inserted into the connecting bar 302 and the connecting plate 104 to install the crash barrier 3 .

[0030] Combined with attachment Figure 2 and attached Figure 3 As shown, the outer wall of the cross-section of the arc plate 301 is an isosceles trapezoidal structure and the inner wall is an arc structure. The arc plate 301 is located outside the installation groove 102, and the connecting strip 302 does not contact the inner wall of the installation groove 102.

[0031] Through the above structure, the outer wall of the arc plate 301 with an isosceles trapezoidal structure increases the contact area with the vehicle, and the inner wall of the arc plate 301 with an arc structure increases the supporting force of the arc plate 301. The anti-collision guardrail 3 does not have a hard contact with the support member 1, reducing the impact force on the support member 1 and protecting the support member 1.

[0032] Example 2

[0033] Based on the first embodiment, please refer to the attached Figure 2 A warning strip groove 4 is provided in the middle of the outer wall of the arc plate 301 away from the support member 1.

[0034] Through the above structure of the second embodiment, by pasting the reflective warning strip inside the warning strip pasting groove 4, it plays a role of prompting at night.
