Abstract

A bridge with lifting guard bars comprises a bridge body (1) and a plurality of guard bar units (2) installed on the bridge body (1). Each guard bar unit (2) comprises two fixing sleeving columns (4) fixed to the bridge body (1) in left and right symmetry, an upper cross beam (21) and a lower cross beam (22); the upper cross beam (21) and the lower cross beam (22) stretch across and extend beyond the two fixing sleeving columns (4); the upper cross beam (21) and the lower cross beam (22) are both provided with circuit elements and fixedly connected with each other through vertical handrails (23); each fixing sleeving column (4) is provided with a screw hole matched with a corresponding vertical screw column (43) in a threaded mode; and one end of each vertical screw column (43) extends into the upper cross beam (21) and is fixedly connected with the upper cross beam (21) through an upthrust bearing (431) and a downthrust bearing (432).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge with liftable guardrails. Background technique [0002] There are often guardrails on both sides of the road surface of the bridge to ensure traffic safety on the bridge road surface. On some bridge facilities, in order to provide lighting, aesthetics and safety indicator lights, the guardrails of bridges are often provided with electrical components such as circuits. Electrical components such as these circuits should often prevent water from entering and affecting normal use. At the same time, other devices that are easily affected by ponding or other road surface interference factors may also be installed at the bottom beam of the bridge guardrail, such as some sensing devices or beautiful decorative materials. Therefore, in some specific situations, it becomes necessary to adjust the height of the guardrail to avoid damage to the guardrail (especially the bottom of the guard...
