Description

Technical Field

[0001] This utility model belongs to the technical field of road traffic safety facilities, specifically relating to a connection device between a concrete guardrail and a corrugated beam guardrail. Background Technology

[0002] Currently, concrete guardrails and corrugated beam guardrails are two commonly used protective facilities in road engineering. Concrete guardrails are characterized by high rigidity and outstanding impact resistance, making them suitable for road sections with large embankment heights and a high risk of vehicles running off the road. Corrugated beam guardrails, on the other hand, are widely used in general road sections due to their good flexibility and ability to absorb collision energy through deformation.

[0003] However, the connection between the corrugated beam guardrail and the concrete guardrail is mainly achieved through the transition section of the wing wall. But this method requires the separate pouring of concrete wing walls, which is quite troublesome and increases the amount of work and construction costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a connection device for concrete guardrails and corrugated beam guardrails.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a connection device for concrete guardrails and corrugated beam guardrails, including a connector, a main support member installed below the connector, a cavity I inside the connector, a baffle I installed inside the cavity I, a through hole I on the side of the connector, a through hole II on the side of the connector away from the through hole I, a concrete guardrail fitting inside the through hole I, a corrugated beam guardrail fitting inside the through hole II, a limiting mechanism I installed inside the cavity I near the concrete guardrail, and a limiting mechanism II installed inside the cavity I near the corrugated beam guardrail.

[0006] Preferably, the limiting mechanism includes a bidirectional screw and a drive fixing assembly. The bidirectional screw passes through both sides of the cavity and has two limiting plates fitted on it. The two limiting plates are arranged opposite to each other, and the concrete guardrail is located between the two limiting plates. The drive fixing assembly is installed on the outside of the connector and is fitted with the end of the bidirectional screw.

[0007] Preferably, the limiting mechanism 2 includes two sliding parts 1 and two fixing parts 1. Both sides of the connecting member are provided with through holes 3. The two sliding parts 1 are respectively located in the through holes 3 on both sides of the connecting member. The ends of the two sliding parts 1 are each equipped with a limiting plate 2. The corrugated beam guardrail is located between the two limiting plates 2. The two fixing parts 1 are respectively installed on both sides of the connecting member. The side of the fixing part 1 is provided with a fixing hole 1. The side of the sliding part 1 is provided with multiple fixing holes 2. A pin 1 is provided between the fixing hole 1 and the corresponding fixing hole 2.

[0008] Preferably, the drive fixing assembly includes a rotating shaft and two fixing parts 2. The rotating shaft is installed at the end of a bidirectional screw, and a handle is installed on the side of the rotating shaft. Both fixing parts 2 are installed on the side of the connector, and both fixing parts 2 have through holes 4. A sliding part 2 is slidably connected in the through holes 4. An arc-shaped clamping part is installed at the end of the sliding part 2. Fixing holes 3 are opened on the side of the two fixing parts 2, and multiple fixing holes 4 are opened on the side of the sliding part 2. A pin 2 is provided between the fixing holes 3 and the corresponding fixing holes 4. The arc-shaped clamping part is engaged with the outer periphery of the rotating shaft.

[0009] Preferably, a guide rod is installed inside the cavity, and the guide rod passes through two limiting plates, both of which are slidably connected to the guide rod.

[0010] Preferably, the connector has multiple buffer components mounted on its side, each of which includes a buffer head and a connecting post. The connecting post is mounted on the side of the connector, and the buffer head is mounted on the end of the connecting post.

[0011] Preferably, a buffer spring is installed between the connector and the buffer head, and the connecting post is located between the buffer springs.

[0012] Preferably, the main support member is detachably connected to a side support member one on the side near the concrete guardrail, and the main support member is detachably connected to a side support member two on the side near the corrugated beam guardrail.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] (1) The existing connection between the corrugated beam guardrail and the concrete guardrail is through the transition section of the wing wall. However, this utility model sets a connector between the corrugated beam guardrail and the concrete guardrail, and the connector has a cavity. The concrete guardrail is fixed by the first through hole and the limiting mechanism, and the corrugated beam guardrail is fixed by the second through hole and the limiting mechanism. This can greatly improve the connection stability between the corrugated beam guardrail and the concrete guardrail, and there is no need to pour it separately, which reduces the amount of construction work and construction cost.

[0015] (2) The two limiting plates driven by the bidirectional screw can fit tightly against both sides of the concrete guardrail, and with the guidance of the guide rod, ensure that the clamping process is accurate and stable; at the same time, the arc-shaped clamping parts in the drive fixing assembly can lock the rotating shaft from both sides, effectively preventing the bidirectional screw from loosening and further strengthening the fixing effect of the concrete guardrail.

[0016] (3) The buffer assembly uses a rubber buffer head combined with a buffer spring, which can absorb the impact force when the guardrail is hit, reduce the damage to the connecting device and the guardrail body, and extend the service life of the overall structure.

[0017] (4) The main support component is combined with the side support component one and the side support component two with triangular cross sections to form a stable triangular support structure, which significantly improves the overall load-bearing capacity and anti-overturning performance of the device, and ensures that the structure can remain stable under complex road conditions or external forces.

The concrete guardrail 1 is located between the two limiting plates 11. The drive fixing assembly is installed on the outside of the connector 2 and is fitted with the end of the bidirectional screw 12.

[0031] like Figures 1-3 As shown, the limiting mechanism 2 includes two sliding parts 7 and two fixing parts 8. Both sides of the connecting part 2 are provided with through holes 3. The two sliding parts 7 are respectively located in the through holes 3 on both sides of the connecting part 2. Limiting plates 2 are installed at the ends of the two sliding parts 7. The corrugated beam guardrail 3 is located between the two limiting plates 2. The two fixing parts 8 are respectively installed on both sides of the connecting part 2. The side of the fixing part 8 is provided with fixing holes 1. The side of the sliding part 7 is provided with multiple fixing holes 2. A pin 9 is provided between the fixing holes 1 and the corresponding fixing holes 2.

[0032] like Figures 1-5 As shown, the drive fixing assembly includes a rotating shaft 16 and two fixing parts 18. The rotating shaft 16 is installed at the end of the bidirectional screw 12. A handle is installed on the side of the rotating shaft 16. The two fixing parts 18 are installed on the side of the connector 2. Both fixing parts 18 have through holes 4. A sliding part 19 is slidably connected in the through holes 4. An arc-shaped clamping part 17 is installed at the end of the sliding part 19. Fixing holes 3 are opened on the side of the two fixing parts 18. Multiple fixing holes 4 are opened on the side of the sliding part 19. A pin 20 is provided between the fixing hole 3 and the corresponding fixing hole 4. The arc-shaped clamping part 17 is engaged with the outer periphery of the rotating shaft 16.

[0033] like Figure 3 As shown, a guide rod 14 is installed inside the cavity, and the guide rod 14 passes through two limiting plates 11. Both limiting plates 11 are slidably connected to the guide rod 14.

[0034] like Figures 1-4 As shown, multiple buffer components are installed on the side of the connector 2. Each buffer component includes a buffer head 10 and a connecting post 15. The connecting post 15 is installed on the side of the connector 2, and the buffer head 10 is installed at the end of the connecting post 15.

[0035] like Figures 1-4 As shown, a buffer spring is installed between the connector 2 and the buffer head 10, and the connecting post 15 is located between the buffer springs.

[0036] like Figures 1-4 As shown, the main support member 4 is detachably connected to a side support member 5 on the side near the concrete guardrail 1, and the main support member 4 is detachably connected to a side support member 6 on the side near the corrugated beam guardrail 3.

[0037] In this utility model, the cross-sections of side support member 5 and side support member 6 are both triangular structures.

[0038] In this invention, the buffer head 10 is made of rubber.

[0039] In this utility model, the two arc-shaped clamping members 17 corresponding to the two fixing members 18 are arranged opposite to each other.

[0040] In this utility model, both through hole one and through hole two are connected to cavity one.

[0041] The working principle of this utility model is as follows: During installation, the worker first needs to place the connector 2 in a suitable position, that is, the constructed concrete guardrail 1 is located in the through hole. Then, one end of the main support 4 is fixed to the connector 2, and the other end is fixed to the ground. The worker drives the bidirectional screw 12 to rotate by the handle. Since the two limiting plates 11 cooperate with the bidirectional screw 12 and are set opposite to each other, the rotation of the bidirectional screw 12 will drive the two limiting plates 11 to slide relative to each other or towards each other along the guide rod 14, so that the two limiting plates 11 gradually approach each other until they are tightly attached to both sides of the concrete guardrail 1, thus completing the limiting of the concrete guardrail 1. After the limiting plates 11 clamp the concrete guardrail 1, the sliding part 19 on the fixing part 2 18 is pushed, so that the two arc-shaped clamping parts 17 clamp from both sides of the rotating shaft 16. Tighten, then use pin 20 to pass through the fixing holes 3 and 4 corresponding to the fixing parts 18 and 19 to fix the position of the arc-shaped clamping part 17, thereby locking the rotating shaft 16 and preventing the double screw 12 from loosening, further ensuring the fixed stability of the concrete guardrail 1; then place the corrugated beam guardrail 3 to be constructed into the through hole 2, and the workers push the sliding parts 7 on both sides so that the two limiting plates 2 approach and clamp from both sides of the corrugated beam guardrail 3. At this time, the fixing hole 2 on the side of the sliding part 7 is aligned with the fixing hole 1 on the side of the fixing part 8, and the pin 9 can be inserted to fix the position of the sliding part 7. Finally, the workers detachably connect the side support 5 and the side support 6 to the two sides of the main support 4, and the lower sides of the side support 5 and the side support 6 also need to be fixed to the ground.
