The invention discloses an assembled bridge guardrail. The assembled bridge guardrail comprises a plurality of stand columns which are arranged in a ladder manner at an interval and a guardrail rod connected between the stand columns; each stand column comprises a vertically-arranged C-shaped steel plate and a flat plate base arranged at the bottom of the C-shaped steel plate, and two sliding blocks are arranged in each C-shaped steel plate; two threaded holes are formed in each sliding block, and the two ends of the guardrail rod are each provided with a waist hole; and the ends of the guardrail rod are connected with the corresponding sliding blocks respectively, and bolts corresponding to bole holts are arranged in the waist holes. By means of the assembled bridge guardrail, sliding of the sliding blocks in the C-shaped steel plates is utilized for conveniently adjusting the angle of the guardrail, and the guardrail is firm in structure and convenient to adjust, has the good adaption to the bridge surface slope, and is suitable for guardrail mounting of various bridges or ladders.
Description
technical field [0001] The invention relates to the field of bridge engineering, in particular to an assembled bridge guardrail. Background technique [0002] There are usually guardrails on both sides of the bridge for safety protection. In order to improve construction efficiency, the guardrails are mostly standard parts processed according to the drawings, which are directly transported to the bridge for assembly and installation, and are connected by bolts or welded to ensure a firm structure. [0003] When installing guardrails on straight bridges, the installation error is small and the construction speed is fast. However, due to angle problems, the construction of stepped bridges or arc bridges is difficult, and even cannot be installed due to large component errors, requiring rework, which affects improved construction efficiency. Contents of the invention [0004] The technical problem mainly solved by the invention is to provide an assembled bridge guardrail, w...
