Description

Metal beam column type bridge guardrail Technical Field The utility model relates to the technical field of bridge construction, in particular to a metal beam column type bridge guardrail. Background In the use of road and bridge, anticollision barrier is an important measure of guarantee driving safety, and when the guardrail received the car striking, collision load passed through the crossbeam and transmitted to the stand, and the anchor connection of rethread stand bottom transmits the girder, and the reliable connection between anticollision barrier and road and bridge has been guaranteed to the anchor mode of stand bottom. However, when the collision load exceeds the bearing value of the guardrail, the stand column and the bridge flange plate are anchored, so that the stand column drives the bridge flange plate anchored at the bottom to deform after being collided, the bridge flange plate is damaged, the bridge structure is affected, the later maintenance is difficult, and the whole use of the bridge is affected. Meanwhile, the existing guardrail is inconvenient to install between the upright posts and the cross beams, two people often need to work simultaneously, one person lifts the cross beams to the appointed positions of the upright posts, and the other person is fixed, so that the installation efficiency is low. Disclosure of utility model The utility model aims to provide a metal beam column type bridge guardrail, which aims to solve the problems in the background technology. The aim of the utility model is realized by the following technical scheme: the utility model provides a metal beam column formula bridge guardrail, includes stand, crossbeam, the stand anchor is on the flange plate, the crossbeam with the stand is connected, the stand is kept away from a side bottom of crossbeam is equipped with the recess, the stand is close to one side of crossbeam is equipped with angle steel and lower angle steel, go up the angle steel with lower angle steel symmetrical arrangement, the crossbeam is located go up the angle steel with between the angle steel down. Further, the lower angle steel is welded with the cross beam, the upper angle steel is connected with the cross beam through bolts, and the cross beam is connected with the upper angle steel and the lower angle steel through bolts. Further, the stand is H-shaped structure, the stand with one side that the crossbeam is connected with the flange plate is perpendicular, the stand is kept away from one side of crossbeam is the inclined plane, be equipped with a plurality of connecting plates in the stand, the connecting plate with the flange plate is parallel. Further, the cross section of the cross beam is D-shaped, the vertical surface of the cross beam is abutted to the upright post, connecting pipes are arranged in two adjacent cross beams, and the two adjacent cross beams are connected with the connecting pipes through bolts.
