Bridge deck steel guardrail embedded part positioning structure

Abstract

The invention discloses a bridge deck steel guardrail embedded part positioning structure. The structure comprises steel guardrail embedded parts on the left side and the right side, the steel guardrail embedded parts on the left side and the right side are located on the two sides in a transverse pouring groove, a longitudinal pouring groove is vertically formed in the middle of the transverse pouring groove, a transverse reinforcement cage is arranged in the transverse pouring groove, and a longitudinal reinforcement cage is arranged in the longitudinal pouring groove; each steel guardrail embedded part comprises a steel guardrail embedded part bottom plate, three screws are arranged on each of the two sides of the upper end face of the steel guardrail embedded part bottom plate, and positioning blocks are movably arranged on the three screws on the same side. According to the invention, the steel guardrail embedded parts are simple to fix, the relative position of the steel guardrail embedded parts can be accurately controlled, construction similar to that of the guardrail embedded parts can be met, the quality problem that a bridge deck steel guardrail cannot be installed subsequently or the guardrail line type is not straight due to insufficient installation accuracy of the embedded parts is solved, and the bridge deck steel guardrail embedded part has the beneficial effects of being good in overall stability and easy to operate.

Description

technical field [0001] The invention relates to a lateral positioning structure, in particular to a positioning structure for embedded parts of steel guardrails on a bridge deck. Background technique [0002] In the steel structure bridge system, the bridge deck guardrail is the most intuitive structure on the bridge surface, and the line type and elevation of its embedded parts are the key to the construction quality control. During the construction process of the PLTJ-12 section of the PLTJ-12 section of the Pingtang-Luodian section of the Yuqing-Anlong Expressway in Guizhou Province, the bridge deck steel guardrail embedded parts in the prior art are in the pouring process. The embedded parts of the steel guardrail are difficult to fix and are prone to offset, which leads to the inability to install the steel guardrail on the bridge deck in the subsequent installation of the embedded parts of the steel guardrail or the quality problem that the line of the guardrail is not...

Problems solved by technology

During the construction process of the PLTJ-12 section of the PLTJ-12 section of the Pingtang-Luodian section of the Yuqing-Anlong Expressway in Guizhou Province, the bridge deck steel guardrail embedded parts in the prior art are in the pouring process. The embedded parts of the steel guardrail are difficult to fix and are prone to offset, which leads to the inability to install the steel guardrail on the bridge deck in the subsequent installation of the embedded parts of the steel guardrail or the quality problem that the line of the guardrail is not straight due to insufficient installation accuracy of the embedded parts. Excavating the offset steel guardrail embedded parts and re-casting the steel guardrail embedded parts is labor-intensive and costly, and the steel structure on the original steel guardrail embedded parts will be destroyed during the excavation-re-pouring process. Reduce the overall stability of the bridge deck steel guardrail embedded parts, resulting in poor impact resistance on the bridge deck steel guardrail embedded parts; at the same time, it is strictly forbidden to use welding and fixing methods during the installation process of steel guardrail embedded parts to avoid the influence of high temperature and current The performance of the embedded parts of the steel guardrail, so the fixing of the embedded parts of the steel guardrail is difficult and complicated
