Abstract

The invention provides an ascending and descending railing structure for a municipal bridge. The ascending and descending railing structure for the municipal bridge comprises a bridge base body (1) and a plurality of railing units (2) arranged on the bridge base body (1), wherein each railing unit (2) comprises two fixed sleeve upright posts (4), an upper cross beam (21) and a lower cross beam (22); the two fixed sleeve upright posts (4) are symmetrically fixed on the bridge base body (1) at the left side and the right side; the upper cross beam (21) and the lower cross beam (22) transversely span across and extend through a position between the two fixed sleeve upright posts (4); the upper cross beam (21) and the lower cross beam (22) are respectively provided with circuit devices and are fixedly connected by vertical railings (23); each of the two fixed sleeve upright posts (4) is provided with a screw hole matched with a vertical stud (43) through screw threads; the upper end of each vertical stud (43) extends into the upper cross beam (21) and is axially and fixedly connected with the upper cross beam (21) through an upper thrust bearing (431) and a lower thrust bearing (432).

Description

technical field [0001] The invention relates to the field of bridges, in particular to a liftable guardrail structure for municipal bridges. 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 ...
