Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated guardrails and relates to a staggered buffer corrugated guardrail structure. Background Art

[0002] Corrugated guardrails are anti-collision structures commonly used on both sides of roads. When a vehicle hits a corrugated guardrail, the impact force can be dispersed and buffered by the corrugated force-bearing surface of the corrugated guardrail. Existing corrugated guardrails usually have only one layer of corrugated anti-collision plate structure. Since the contact area between one layer of corrugated anti-collision plate structure and the vehicle collision is limited, when the impact force of the vehicle hitting the corrugated guardrail is large, it is difficult to effectively buffer and reduce the impact force with only one layer of corrugated anti-collision plate structure. Especially for freight vehicles with larger tonnage, their own weight is very large, and the impact force on the guardrail is huge. Existing corrugated guardrails are difficult to effectively buffer and dissipate energy when subjected to huge impacts, and their protective strength is limited.

[0003] Therefore, in order to solve the defects of the existing corrugated guardrails, such as limited protection strength and limited buffering contact area, the utility model discloses a corrugated guardrail structure with staggered buffering. Utility Model Content

[0004] The purpose of the utility model is to provide a corrugated guardrail structure with staggered buffering, which can effectively increase the buffering force-bearing area and thus improve the protective performance of the corrugated guardrail.

[0005] The utility model is achieved through the following technical solutions:

[0006] A staggered-level buffer corrugated guardrail structure includes a mounting post, a connecting seat fixedly mounted on one side of the mounting post, a first corrugated guardrail mounted on the end of the connecting seat away from the mounting post, and a second corrugated guardrail mounted on the side of the first corrugated guardrail close to the mounting post via a connecting piece; a gap is left between the first corrugated guardrail and the second corrugated guardrail, and the crest of the second corrugated guardrail is located inside the deformation and bending area of the first corrugated guardrail.

[0007] The first corrugated guardrail is first impacted by a vehicle, bending and deforming to provide primary impact protection. The bent first corrugated guardrail then contacts the second corrugated guardrail, transferring the impact force to the second corrugated guardrail, which then bends and deforms to provide secondary impact protection. By creating a staggered guardrail structure with the first and second corrugated guardrails, the impact protection area is increased, improving the corrugated guardrail's impact protection performance.

[0008] In order to better realize the present utility model, further, the first corrugated guardrail includes at least two crests, a connecting piece is installed on the side of the crest close to the mounting column, a clamping block is provided on one end of the connecting piece close to the second corrugated guardrail, and a clamping groove corresponding to the clamping block is provided on the side of the second corrugated guardrail close to the connecting piece.

[0009] In order to better realize the present invention, further, a connecting seat is provided at one end of the connecting member close to the first corrugated guardrail, and the connecting seat is fixedly connected to one side of the crest of the first corrugated guardrail.

[0010] In order to better implement the present invention, further, at least one set of notches is provided in the area between the two ends of the connecting piece.

[0011] In order to better realize the present invention, further, a first through hole is provided at the crest and / or trough of the first corrugated guardrail, and a second through hole is provided at the crest and / or trough of the second corrugated guardrail. Connecting bolts are inserted in the first through hole and the second through hole, and one end of the connecting bolt is matched with the threaded hole on the connecting seat.

[0012] In order to better realize the present utility model, further, the connecting seat includes a first connecting plate, a second connecting plate, and a connecting beam. The first connecting plate and the second connecting plate are symmetrically distributed on both sides of the mounting column, and the first connecting plate and the second connecting plate are connected by a connecting beam; a connecting bolt is passed through the first connecting plate and the second connecting plate, and a through hole for the connecting bolt to pass through is provided on the mounting column.

[0013] In order to better realize the present invention, further, the gap between the first corrugated guardrail and the second corrugated guardrail is 1-3 cm.

[0014] In order to better implement the present invention, further, an anti-glare strip is provided on the side of the first corrugated guardrail away from the installation column.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] The utility model arranges the first corrugated guardrail and the second corrugated guardrail in sequence, and makes the crest of the second corrugated guardrail located inside the bending deformation zone of the first corrugated guardrail, so that the first corrugated guardrail is first hit to perform primary buffering and energy dissipation, and at the same time, the first corrugated guardrail contacts the second corrugated guardrail after bending and deformation, and transmits the impact force to the second corrugated guardrail, which performs secondary buffering and energy dissipation through the bending deformation of the second corrugated guardrail, which is equivalent to indirectly increasing the buffering force area, thereby significantly improving the anti-collision performance of the corrugated guardrail.

[0030] The bottom end of the mounting column 1 is pre-buried under the ground as a pile foundation. A connecting seat 2 is provided on the side of the mounting column 1 located above the ground and close to the road. A first corrugated guardrail 3 is fixedly installed on the end of the connecting seat 2 away from the mounting column 1, that is, on the end of the connecting seat 2 close to the road. The first corrugated guardrail 3 serves as a first-level anti-collision buffer structure. A second corrugated guardrail 5 is detachably mounted on the side of the first corrugated guardrail 3 away from the road through a connector 4, and the crest of the second corrugated guardrail 5 is located inside the deformed bending area of the first corrugated guardrail 3. When a vehicle hits the first corrugated guardrail 3, the first corrugated guardrail 3 performs the first-level buffering and anti-collision. At the same time, the first corrugated guardrail 3 bends and deforms under the action of the impact force. The bent and deformed first corrugated guardrail 3 contacts the second corrugated guardrail 5, further transmitting the impact force to the second corrugated guardrail 5. The second corrugated guardrail 5 performs the second-level buffering of the impact, which is equivalent to indirectly increasing the impact force area, effectively improving the buffering and anti-collision effect of the corrugated guardrail.

[0031] Example 2:

[0032] A staggered buffer corrugated guardrail structure is improved on the basis of embodiment 1, such as Figure 5 and Figure 6As shown, the first corrugated guardrail 3 includes at least two crests, and a connecting member 4 is installed on the side of the crest close to the mounting column 1, and a clamping block 41 is provided on the end of the connecting member 4 close to the second corrugated guardrail 5, and a clamping groove 51 corresponding to the clamping block 41 is provided on the side of the second corrugated guardrail 5 close to the connecting member 4; a connecting seat is provided on the end of the connecting member 4 close to the first corrugated guardrail 3, and the connecting seat is fixedly connected to one side of the crest of the first corrugated guardrail 3.

[0033] One end of the connector 4 is provided with a connection seat, which is fixedly connected to one side of the first corrugated guardrail 3 by welding or bolting. The other end of the connector 4 is provided with a T-shaped clamping block 41. A T-shaped clamping slot 51 is provided on one side of the second corrugated guardrail 5 to correspond with the clamping block 41. By directly engaging the clamping slot 51 with the clamping block 41, the second corrugated guardrail 5 can be quickly and conveniently installed on the side of the first corrugated guardrail 3. In actual use, the second corrugated guardrail 5 can be removed for sections of road with less impact.

[0034] Furthermore, at least one group of notches 42 is provided in the area between the two ends of the connecting member 4. By providing the notches 42, when the first corrugated guardrail 3 is hit, the connecting member 4 can bend and deform along the direction of the notches 42, thereby assisting the first corrugated guardrail 3 to bend and deform and contact the second corrugated guardrail 5.
