Abstract

The invention discloses a bridge with an adjustable guardrail height. The bridge comprises a bridge foundation (1) and multiple guardrail units (2) mounted on the bridge foundation (1). Each guardrail unit (2) comprises two fixed sleeve columns (4), an upper beam (21) and a lower beam (22), wherein the two fixed sleeve columns (4) are fixed to the bridge foundation (1) in a bilateral symmetry mode, the upper beam (21) and the lower beam (22) stretch across and beyond the space between the two fixed sleeve columns (4), and the upper beam (21) and the lower beam (22) are both provided with circuit devices and fixedly connected through a vertical handrail (23); a threaded hole in screw-thread fit with a vertical stud (43) is formed in each of the two fixed sleeve columns (4), and the upper end of each vertical stud (43) stretches into the upper beam (21) and is fixedly connected with the upper beam (21) in the axial direction 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 bridge with adjustable guardrail heights. 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 ...
