Description

Technical Field

[0001] This utility model relates to the field of safety guardrail technology, and more specifically, to a guardrail for highway bridges. Background Technology

[0002] As a key node in modern transportation networks, the safety performance of highway bridges is of paramount importance. Bridge railings are passive safety protection facilities installed on the sides or central median of bridges. Their main functions include: blocking and guiding, protecting pedestrians and non-motorized vehicles, and providing visual guidance.

[0003] While existing bridge railings play a vital role in ensuring traffic safety, they still have some drawbacks. Some railings have insufficient impact resistance, resulting in poor energy absorption and excessive acceleration transferred to vehicle occupants during collisions, potentially causing serious injuries or fatalities. Furthermore, railings can be penetrated, broken, or excessively deformed, allowing vehicles to veer off the bridge. Existing railing designs often neglect the high humidity and water accumulation issues common in bridge environments. Rainwater and snowmelt tend to accumulate at the railing base, failing to drain quickly. Prolonged water accumulation keeps metal components in a constantly damp environment, significantly accelerating electrochemical corrosion. Therefore, there is an urgent need to design a new type of highway bridge railing to address these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a guardrail for highway bridges to solve the technical problems mentioned in the background art, such as low anti-collision performance, lack of effective drainage mechanism, and easy rusting and corrosion of the base.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A guardrail for highway bridges includes a base, a drainage mechanism, a buffer mechanism, and a reinforcement mechanism. The base is fixed to the ground at both ends by bolts. A horizontal bar is connected to the upper surface of the base, and three vertical bars are connected to the upper surface of the horizontal bar. A second horizontal bar is connected to the upper surface of each vertical bar, and connecting rods connect the vertical bars. The drainage mechanism is connected to the lower surface of the base. The drainage mechanism includes a filter screen and a V-shaped plate. The filter screen is V-shaped, and its side is connected to the side of the V-shaped plate. The upper surfaces of the filter screen and the V-shaped plate are connected to the lower surface of the base. The buffer mechanism includes a pressure plate and a fixing component. The fixing component is connected to the surface of the connecting rod, and the pressure plate is connected to the fixing component. The pressure plate has an arc-shaped design. The reinforcement mechanism is connected to the connecting rod.

[0009] This invention is further configured such that a first drainage groove is formed on the side of the filter screen, and a second drainage groove is formed on the side of the V-shaped plate. This dual-stage drainage system prevents impurities from clogging the system, ensuring smooth drainage and effectively preventing water accumulation.

[0010] This invention is further configured such that the fixing assembly comprises four sets, including a mounting plate, a connecting block, and a locking bolt. One side of the mounting plate is connected to a connecting rod, and the other side is connected to a connecting block. The mounting plate is connected to the connecting rod via the locking bolt, and one side of the connecting block is connected to a pressure plate. Upon impact, the pressure plate absorbs most of the impact force, and the remaining impact force is transmitted to the mounting plate and dispersed through the connecting block. Simultaneously, the locking bolt design facilitates the replacement of damaged pressure plates.

[0011] The present invention is further configured such that the reinforcement mechanism includes a reinforcing plate, a reinforcing rod, and a support base. The reinforcing plate is disposed between the connecting rods. A reinforcing rod is connected to one side of the reinforcing plate, and a support base is connected to the other end of the reinforcing rod. The reinforcing rod provides oblique support, and the triangular reinforcement system significantly improves the impact resistance of the guardrail.

[0012] The present invention is further configured such that a damping plate is connected to the lower end face of the support base. The damping plate absorbs the vibration transmitted by the reinforcing rod, reduces structural resonance and noise caused by vehicle impact, reduces the impact on the ground anchor point, and maintains the stability of the installation.

[0013] The present invention is further provided that a support sleeve is fitted onto the surface of the reinforcing rod. The support sleeve prevents the reinforcing rod from bending and deforming under pressure, thereby further improving the stability of the guardrail.

[0014] This invention is further configured such that three sets of mounting seats are provided on the upper end face of the second crossbar, and lighting lamps are provided on the upper end face of the mounting seats. The lighting lamps improve road safety under low visibility conditions.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a guardrail for highway bridges, which has the following beneficial effects:

[0017] 1. This utility model is equipped with a drainage mechanism. Rainwater flows into the first drainage trough along the inclined surface of the V-shaped filter screen. The filter screen effectively intercepts impurities such as leaves. The rainwater is guided by the V-shaped plate to the second drainage trough for centralized discharge. The dual-stage drainage avoids blockage by impurities, ensures smooth drainage, effectively prevents water accumulation, and eliminates corrosion in the contact area between the base and the ground.

[0018] 2. This utility model is equipped with a buffer mechanism. If a vehicle hits the pressure plate, the arc-shaped pressure plate absorbs most of the impact force, and the remaining impact force is transmitted to the mounting plate through the connecting block, and then dispersed to the connecting rod and the overall frame to achieve effective buffering. At the same time, the locking bolt connection design makes it easy to replace the damaged pressure plate.

[0019] 3. This utility model is equipped with a reinforcement mechanism. After the impact force is dispersed by the buffer mechanism, it is transmitted obliquely to the support seat through the reinforcing plate to the reinforcing rod. The damping plate absorbs the vibration transmitted by the reinforcing rod, reducing structural resonance and noise caused by vehicle collision, reducing the impact on the ground anchor point, and maintaining the stability of the installation. The reinforcing rod is obliquely supported, and the triangular reinforcement system greatly improves the impact resistance of the guardrail. The support sleeve prevents the reinforcing rod from bending and deforming under pressure, further improving the stability of the guardrail. Attached Figure Description

[0029] Please see Figures 1-5 A guardrail for highway bridges includes a base 1, a drainage mechanism, a buffer mechanism, and a reinforcement mechanism. The base 1 is fixed to the ground at both ends by bolts 2. A horizontal bar 3 is connected to the upper surface of the base 1. Three vertical bars 4 are connected to the upper surface of the horizontal bar 3. A second horizontal bar 5 is connected to the upper surface of each vertical bar 4. A connecting rod 6 connects the vertical bars 4. The drainage mechanism is connected to the lower surface of the base 1. The drainage mechanism includes a filter screen 7 and a V-shaped plate 8. The filter screen 7 is V-shaped, and its side is connected to the side of the V-shaped plate 8. The upper surfaces of the filter screen 7 and the V-shaped plate 8 are connected to the lower surface of the base 1. The buffer mechanism includes a pressure plate 9 and a fixing component. The fixing component is connected to the surface of the connecting rod 6. The pressure plate 9 is connected to the fixing component and has an arc-shaped design. The reinforcement mechanism is connected to the connecting rod 6.

[0030] In a further embodiment, the filter screen 7 has a drainage groove 10 on its side, and the V-shaped plate 8 has a drainage groove 11 on its side. The V-shaped filter screen 7 intercepts impurities such as leaves, and rainwater flows into the drainage groove 10 along the inclined surface, and is then guided by the V-shaped plate 8 to the drainage groove 11 for centralized discharge. This dual-stage drainage avoids blockage by impurities, ensures smooth drainage, and effectively prevents water accumulation.

[0031] In a further embodiment, the fixing assembly comprises four sets, including a mounting plate 12, a connecting block 13, and a locking bolt 14. One side of the mounting plate 12 is connected to the connecting rod 6, and the other side is connected to the connecting block 13. The mounting plate 12 is connected to the connecting rod 6 via the locking bolt 14, and one side of the connecting block 13 is connected to the pressure plate 9. If a vehicle impacts the pressure plate 9, the arc-shaped pressure plate 9 absorbs most of the impact force, and the remaining impact force is transmitted to the mounting plate 12 via the connecting block 13, and then dispersed to the connecting rod 6 and the overall frame, achieving effective buffering. Simultaneously, the locking bolt 14 is designed to facilitate the replacement of damaged pressure plates 9.

[0032] In a further embodiment, the reinforcement mechanism includes a reinforcing plate 15, a reinforcing rod 16, and a support base 17. The reinforcing plate 15 is disposed between the connecting rods 6, and the reinforcing rod 16 is connected to one side of the reinforcing plate 15. The other end of the reinforcing rod 16 is connected to the support base 17. A damping plate 18 is connected to the lower end face of the support base 17. A support sleeve 19 is fitted onto the surface of the reinforcing rod 16. The reinforcing rod 16 obliquely transmits the impact force to the support base 17. The damping plate 18 absorbs the vibration transmitted by the reinforcing rod 16, reducing structural resonance and noise caused by vehicle impact, reducing the impact on the ground anchor point, and maintaining installation stability. The support sleeve 19 prevents the reinforcing rod 16 from bending and deforming under pressure, further improving the stability of the guardrail.

[0033] In a further embodiment, three sets of mounting seats 20 are provided on the upper end face of the second crossbar 5, and lighting lamps 21 are provided on the upper end face of the mounting seats 20. The lighting lamps 21 cover the outline of the guardrail and improve nighttime visibility.

[0034] In summary, when using the overall equipment:

[0035] In this invention, the base 1 is rigidly anchored to the ground by bolts 2, forming a stable foundation. When it rains, rainwater flows into the drainage trough 10 along the inclined surface of the V-shaped filter screen 7. The filter screen effectively intercepts impurities such as leaves. The rainwater is guided by the V-shaped plate 8 to the drainage trough 21 for centralized discharge. The dual-stage drainage avoids blockage by impurities, ensures smooth drainage, effectively prevents water accumulation, and eliminates corrosion in the contact area between the base 1 and the ground.

[0036] If a vehicle collides with the guardrail, the arc-shaped pressure plate 9 absorbs most of the impact force, and the remaining impact force is transmitted to the mounting plate 12 through the connecting block 13. The mounting plate 12 then disperses the impact force to the frame composed of the connecting rod 6 and the vertical rod 4, achieving effective buffering. The impact force is further distributed laterally by the reinforcing plate 15 and transmitted obliquely to the support seat 17 by the reinforcing rod 16. The damping plate 18 absorbs the vibration transmitted by the reinforcing rod 16, reducing structural resonance and noise caused by vehicle collision, reducing the impact on the ground anchor point, and maintaining installation stability. The reinforcing rod 16 provides oblique support, and the triangular reinforcement system greatly improves the guardrail's impact resistance. The support sleeve 19 prevents the reinforcing rod 16 from bending and deforming under pressure, further improving the stability of the guardrail. At the same time, the locking bolt 14 connection design facilitates the replacement of damaged pressure plates 9.

[0037] The lighting 21 is integrated into the top of the crossbar 25 via the mounting bracket 20, projecting a warning light strip at night to clearly outline the guardrail.
