Description

Technical Field

[0001] This utility model relates to the technical field of anti-glare panels, and in particular to an anti-glare panel installation structure for cable-stayed bridges. Background Technology

[0002] Anti-glare panels are traffic safety products manufactured and installed on the central median strip of highways to solve the problem of glare from oncoming vehicle lights. They are mostly installed on the median guardrail or in the middle of the guardrail, and some are also installed on the central opening of the movable guardrail. In terms of material, they are divided into steel anti-glare panels, plastic anti-glare panels, and fiberglass anti-glare panels. In terms of appearance, common types include ordinary straight panels, reverse S-shaped panels, imitation embossed anti-glare panels, and highway landscape anti-glare panels.

[0003] The prior art Chinese utility model patent with application number CN201921985703.9 relates to an installation structure for an anti-glare panel, including an anti-glare panel, a base, mounting holes, screws, an isolation strip, a groove, a locking block, and a spring, which can make the installation of the anti-glare panel more stable and prevent it from being pulled up from the top of the isolation strip by wind force, thereby reducing safety hazards.

[0004] However, in actual use, the aforementioned devices are easily scattered on the road after being damaged by external impacts. Due to the width limitation of the bridge body, the middle of the cable-stayed bridge usually does not have a green area between the two-way roads, meaning that the fragments are easily scattered on the road surface and affect the normal driving of vehicles. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-glare plate installation structure for cable-stayed bridges that facilitates the rapid installation, disassembly, and maintenance of the entire equipment through a connecting device, increases the strength and toughness of the equipment by strengthening the structure to reduce the situation of the equipment breaking and falling apart, and facilitates the adjustment of the effective shielding width of the equipment through an extension device, thereby improving the practicality of the device.

[0006] This utility model discloses an anti-glare panel installation structure for cable-stayed bridges, comprising a connecting device, a reinforcing structure, and an extension device. The reinforcing structure is installed on the connecting device, and the extension device is also installed on the connecting device. The connecting device facilitates the rapid installation, disassembly, and maintenance of the entire device. The reinforcing structure increases the strength and toughness of the device, reducing the likelihood of fragmentation and falling of broken pieces. The extension device allows for adjustment of the effective shielding width of the device, thus improving its practicality.

[0007] Preferably, the connecting device includes an embedded base, embedded reinforcing bars, a limiting protrusion, a connecting seat, and connecting bolts. Multiple sets of embedded reinforcing bars are embedded in the lower part of the bridge deck on the lower end face of the embedded base. A limiting protrusion is provided on the upper end face of the embedded base. A limiting groove is provided at the lower part of the connecting seat. An internal threaded hole is provided on the upper end face of the limiting protrusion. The connecting seat is fixed to the embedded base by connecting bolts. The embedded base and embedded reinforcing bars are embedded in the ground, increasing the stability of the device. The limiting protrusion limits the installation angle of the connecting seat, preventing tilting of the equipment. Furthermore, the connection and fixation by connecting bolts facilitates quick replacement and maintenance of the equipment, improving the practicality of the device.

[0008] Preferably, the reinforcing structure includes a main anti-glare plate, reinforcing steel bars, and wire mesh. The main anti-glare plate is installed on the upper part of the connecting seat. A set of reinforcing steel bars is vertically embedded in the left and right parts of the main anti-glare plate, and a set of wire mesh is embedded in the front and rear parts of the main anti-glare plate. The main anti-glare plate blocks the headlights of vehicles in the oncoming lanes. The reinforcing steel bars increase the overall toughness and strength of the main anti-glare plate. The wire mesh reduces the dispersion and falling of debris after the main anti-glare plate breaks, reducing the impact on driving vehicles and improving the practicality of the device.

[0009] Preferably, the expansion device includes a side-opening slot, a rod, an expansion plate, a limiting connecting rod, a fixed end cap, and fixing bolts. The left and right sides of the side-opening slot each have a set of vertical side-opening slots. An expansion plate is provided on the side of the rod, allowing the rod to be inserted into the side-opening slot. A vertical limiting connecting rod is provided in the lower part of the main anti-glare plate, and a limiting slot is provided on the lower end face of the rod. The fixed end cap covers the top of the main anti-glare plate, and a set of internal threaded grooves is provided on the left and right sides of the upper end face of the main anti-glare plate. The fixed end cap is connected to the upper end face of the main anti-glare plate by fixing bolts. The fixed end cap limits and fixes the position of the rod and facilitates the replacement and maintenance of the expansion plate. Different sizes of expansion plates can be selected according to usage requirements, and the rod can be inserted into the side-opening slot to adjust the effective shading area of ​​the main anti-glare plate, enabling the device to adapt to different working needs. The side-opening slot, rod, and limiting connecting rod limit the expansion plate, improving the stability and practicality of the device.

[0010] Preferably, it also includes air guide holes. Multiple sets of air guide holes are evenly arranged on the main anti-glare panel body, and the air guide holes themselves are inclined at both ends. The air guide holes reduce the impact of gusts on the main anti-glare panel body. At the same time, the air guide holes themselves are in an inclined state, so the parallel headlights of the vehicle cannot pass through the air guide holes to the main anti-glare panel, which improves the practicality and stability of the device.

[0011] Preferably, it also includes side reinforcing ribs, with a set of side reinforcing ribs respectively provided on the left and right sides between the lower part of the main anti-glare plate and the connecting seat; the side reinforcing ribs increase the connection strength between the main anti-glare plate and the connecting seat, reduce the risk of cracks at the connection, and improve the practicality of the device.

[0012] Preferably, it also includes rounded chamfers, with rounded chamfers provided on the edges of the side opening slots on both the left and right sides of the main anti-glare panel; the rounded chamfers reduce the wear caused to the main anti-glare panel body by the vibration of the extension plate when facing the wind, thus improving the practicality of the device.

[0013] Compared with the prior art, the advantages of this utility model are as follows: the connecting device facilitates the quick installation, disassembly and maintenance of the equipment as a whole; the reinforced structure increases the strength and toughness of the equipment, reducing the situation of the equipment breaking and falling apart; and the extension device facilitates the adjustment of the effective shielding width of the equipment, thus improving the practicality of the device.
