Description

Technical Field

[0001] This application relates to the field of traffic guardrail design, and more particularly, to a corrugated guardrail. Background Art

[0002] A corrugated guardrail is a combined corrugated plate movable steel guardrail used at the opening of the central separation belt of a highway. The guardrail consists of two corrugated steel guardrail plates and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail plates.

[0003] When a vehicle travels on the road and rushes out of control towards the corrugated guardrail, the corrugated guardrail usually collapses to absorb the kinetic energy of the vehicle, so as to reduce the impact on the people in the vehicle. The common corrugated guardrail consists of corrugated plates and columns. The corrugated plates are in contact with the columns and fixed by bolts. Therefore, the impact force will directly be guided to the columns through the corrugated plates, and the columns are stably fixed in the foundation, so the reaction force on the vehicle will be very strong, and thus the buffering effect on people is poor. Summary of the Invention

[0004] The content part of this application is used to briefly introduce the concepts, which will be described in detail in the following detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] To solve the technical problems mentioned in the above background art part, some embodiments of this application provide a corrugated guardrail, including: corrugated plates; columns standing on the back of the corrugated plates, with the lower ends of the columns buried underground; a support plate in a U-shape, with both ends of the support plate in contact with the back of the corrugated plates, and the middle part protruding towards the columns and abutting against the columns; a fastening structure for connecting the corrugated plates and the columns.

[0006] Further, the fastening structure includes: screws; a transverse first long circular hole is formed in the middle of the support plate, a threaded through hole coaxial with the first long circular hole is formed in the column, one end of the screw is threadedly connected to the threaded through hole of the column, and the other end of the screw passes through the first long circular hole and is fixed to the corrugated plate.

[0007] Further, the fastening structure includes: screws and washers; a transverse first long circular hole is formed in the middle of the support plate, a threaded through hole coaxial with the first long circular hole is formed in the column, a transverse second long circular hole is formed in the corrugated plate, the washer is pressed on the front of the corrugated plate away from the column, the rod part of the screw is threadedly connected to the threaded through hole of the column, and the head of the screw passes through the first long circular hole and the second long circular hole in sequence and is sleeved with the washer.

[0008] Further, it further includes: a fixing plate; the fixing plate is fixed to the part of the upright column buried underground, and the plate surface of the fixing plate is parallel to the length direction of the corrugated plate.

[0009] Further, it further includes: a fixing plate and a connecting rod; the fixing plate is placed on the side of the upright column away from the corrugated plate, both the connecting rod and the fixing plate are buried underground, one end of the connecting rod is fixed to the part of the upright column buried underground, the other end of the connecting rod is fixed to the fixing plate, and the plate surface of the fixing plate is parallel to the length direction of the corrugated plate.

[0011] Further, it further includes: a reflective bead; the reflective bead is fixed on the upright column, and the reflective bead is placed on the side of the upright column facing the corrugated plate.

[0012] The beneficial effects of the present application are as follows:

[0013] The corrugated plate is connected to the middle of the supporting plate, and the supporting plate is connected to both ends of the upright column. Since the supporting plate is in a U-shape, when a vehicle impacts the corrugated plate, the impact force is first transmitted to the supporting plate, and the middle of the supporting plate sinks towards the upright column to absorb part of the energy, thereby reducing the reaction force transmitted by the upright column to the vehicle and improving the buffering effect on personnel.

[0028] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0029] Refer to Figures 1-5 ,

[0030] A corrugated guardrail includes: a corrugated plate 1, a column 2, a support plate 3 and a fastening structure. The column 2 is placed on the back of the corrugated plate 1, the support plate 3 is placed between the upper end of the column 2 and the back of the corrugated plate 1. The support plate 3 is in a U shape, and both ends of the support plate 3 are in contact with the back of the corrugated plate 1 and fixed by bolts. The middle part of the support plate 3 protrudes towards the column 2 and abuts against the column 2, so that a gap for collapse buffering is formed between the corrugated plate 1 and the column 2. The fastening structure is used to connect the corrugated plate 1 and the column 2, so as to press the corrugated plate 1 towards the column 2 and press it on the support plate 3.

[0031] Specifically, the fastening structure includes: a screw 4. A transverse first long circular hole 31 is formed in the middle of the support plate 3, and a threaded through hole 21 coaxial with the first long circular hole 31 is formed in the upright column 2. The rod portion of the screw 4 is threadedly connected to the threaded through hole 21 of the upright column 2, and the head of the screw 4 passes through the first long circular hole 31 and is fixed to the corrugated plate 1. Since the support plate 3 is sandwiched between the corrugated plate 1 and the upright column 2, it is difficult for the worker to see the position where the rod portion of the screw 4 extends into the support plate 3 during the installation of the screw 4, and the first long circular hole 31 is more convenient for the screw 4 to pass through due to its larger opening area compared with an ordinary circular hole.

[0032] Specifically, it further includes: a fixing plate 5. The fixing plate 5 is welded and fixed to the part of the upright column 2 buried underground, thereby increasing the contact area between the lower part of the upright column 2 and the foundation. The plate surface of the fixing plate 5 is parallel to the length direction of the corrugated plate 1. When the corrugated plate 1 receives an impact force towards the upright column 2, due to the large contact area between the fixing plate 5 and the foundation, the fixing plate 5 can make the upright column 2 stand more stably on the ground and prevent the upright column 2 from tilting.

[0033] In another embodiment, the fastening structure includes: a screw 4 and a washer 8. A transverse first long circular hole 31 is formed in the middle of the support plate 3, a threaded through hole 21 coaxial with the first long circular hole 31 is formed in the upright column 2, a transverse second long circular hole 11 is formed in the corrugated plate 1, the washer 8 is pressed on the front surface of the corrugated plate 1 away from the upright column 2, the rod portion of the screw 4 is threadedly connected to the threaded through hole 21 of the upright column 2, and the head of the screw 4 sequentially passes through the first long circular hole 31 and the second long circular hole 11 and is sleeved with the washer 8. The impact force received by the corrugated plate 1 can be decomposed into a component force coaxial with the screw 4 and a component force perpendicular to the axis of the screw 4. The component force coaxial with the screw 4 causes the corrugated plate 1 and the screw 4 to move towards the upright column 2 along the axis of the threaded through hole 21, thereby forming a buffer. The component force perpendicular to the axis of the screw 4 causes the corrugated plate 1 to slide laterally relative to the screw 4 through the second long circular hole, thereby forming a buffer.

[0034] Specifically, it further includes: a fixing plate 5 and a connecting rod 6. The fixing plate 5 is placed on the side of the upright column 2 away from the corrugated plate 1, both the connecting rod 6 and the fixing plate 5 are buried underground, one end of the connecting rod 6 is welded and fixed to the part of the upright column 2 buried underground, the other end of the connecting rod 6 is welded and fixed to the fixing plate 5, and the plate surface of the fixing plate 5 is parallel to the length direction of the corrugated plate 1, thereby increasing the distance between the fixing plate 5 and the lower part of the upright column 2, increasing the moment of the fixing plate 5 acting on the upright column 2, and increasing the stability of the upright column 2.

[0035] Specifically, an arc surface is formed in the middle of the support plate 3, and the arc surface fits the circumferential surface of the upright column 2, so that the support plate 3 is stably connected to the upright column 2 in the transverse direction.

[0036] Specifically, it further includes: a reflective bead 7. The reflective bead 7 is fixed to the middle of the upright post 2, and the reflective bead 7 is placed on the side of the upright post 2 facing the corrugated plate 1 to remind the driver of the vehicle of the position of the corrugated guardrail by reflection.
