Protective bridge elastic guardrail structure and mounting method

Abstract

The invention discloses a protective bridge elastic guardrail structure and a mounting method, the protective bridge elastic guardrail structure comprises a bearing mechanism and a fixing mechanism, and the fixing mechanism is mounted at the upper end of the bearing mechanism. According to the guardrail structure, an elastic sleeve is connected between a mounting plate and the bottom surface of abearing frame; the outer wall of the side, away from a rescue rod assembly, of the bearing frame is connected with a plurality of buffer columns. A buffer plate is mounted at the front ends of the buffer columns; so that when a vehicle is out of control and collides with the guardrail, the out-of-control vehicle can be buffered for the first time by utilizing the buffer plate and the buffer columns; the impact force is prevented from directly acting on the guardrail to damage the guardrail; meanwhile, when the impact force is too large, a rubber gasket on the elastic sleeve can be used for conducting secondary buffering on the out-of-control vehicle, the head of the out-of-control vehicle can be deflected through a center rotary drum, the direction of the out-of-control vehicle head is turned to a front rail, and casualties caused by the fact that the vehicle easily breaks through the guardrail and falls into a river after colliding with the guardrail are avoided.

Description

technical field [0001] The invention relates to the technical field of bridge guardrails, in particular to a protective bridge elastic guardrail structure and an installation method. Background technique [0002] Highway bridge is a kind of highway erected in the air, which does not occupy the ground, so it can fully improve the efficiency of urban commuting. Highway bridges usually separate the forward lane and the reverse lane, and leave a space between the two highway bridges after separation. There is a gap. When the vehicle is in contact with the guardrail of the highway bridge, if the impact force is too large, the vehicle will easily cross the guardrail and fall to the ground through the gap. There is a great potential safety hazard. The existing solution is to increase the guardrail structural strength, but the effect of this method is not significant. The bridge guardrail refers to the guardrails placed on both sides of the bridge. Its purpose is to prevent out-of-...

This kind of guardrail buffer does not have the effect of buffering energy absorption, and the vehicle is easy to break through the guardrail and fall into the river after a collision

[0003] Patent No. CN201910509417.3 discloses a bridge guardrail structure, which is arranged on both sides of the bridge and includes anti-collision columns distributed at equal intervals. The lower ends of the anti-collision columns are fixedly connected to the steel frames on both sides of the bridge. A horizontal protective plate is arranged between the inner sides of the anti-collision columns, and the horizontal protective plate and each anti-collision column are connected by bolts. The inner sides of both ends of the anti-collision columns are fixed with support rods, and the outer ends of the support rods are A supporting column is arranged between, and a guide roller is arranged on the supporting column, and a connecting seat is provided at the end of the supporting column, and the outer end of the supporting bar is fixedly connected with the inner side of the connecting seat, and the inner end of the supporting bar is connected with the anti- The bumper is fixedly connected, and the two adjacent connecting seats are fixedly connected through the connecting plate. This kind of guardrail does not have the warning function and the adjustment ability is poor.

[0004] The existing bridge guardrails generally do not have the effect of buffering energy absorption. After a vehicle collides, it is easy to break through the guardrail and fall into the river. The warning function is lacking and the adjustment ability is poor.
