Description

Technical Field

[0001] The utility model belongs to the field of positioning of guardrail embedded parts, and specifically relates to a combined steel guardrail embedded part positioning trolley. Background Technique

[0002] Most of the existing bridge guardrails are combined steel guardrails. The combined steel guardrail is a beam structure fixed by columns, and relies on the bending deformation and tensile force of the guardrail to resist vehicle collisions. The anti-collision guardrail has a certain stiffness and toughness, and absorbs the impact energy through the deformation of the cross beam. The combined steel guardrail is mainly composed of components such as cross beams, columns, and bases, and its damaged components are easy to replace. It also has a certain sight guidance effect, can be coordinated with the road alignment, and has a beautiful appearance. The combined steel guardrail relies on the foundation embedded parts for stability. Before installing the guardrail, it is necessary to pre-reserve the guardrail embedded parts on the bridge deck paving layer in advance. The installation quality of the embedded parts directly affects the overall firmness and appearance quality of the subsequent guardrail. Therefore, higher requirements are put forward for the installation of anti-collision guardrail embedded parts.

[0003] The combined steel guardrail has a long design length and a small installation reserved gap, and has extremely high requirements for the installation accuracy of the base embedded parts. Insufficient embedding accuracy will lead to a series of problems such as great difficulty in the subsequent overall assembly of the guardrail and poor guardrail line type. The conventional measurement method is time-consuming and laborious, which is not conducive to on-site construction. Content of the Utility Model
