基于跨路现浇梁预留门洞结构体系的技术研究

Technical Research on the Reserved Door Opening Structure System Based on Cross Road Cast-in-place Beam

本文结合某改建工程跨路口现浇箱梁的工程实施,分析了支架预留临时横穿通道的现场应用和受力验算,阐述贝雷架+钢管立柱形式通道门洞选用的结构构件布设方式对支架体系施工稳定性进行验证分析,确保安全可靠,经济可行,同时能全面保障交叉施工,满足交通通行带来社会效果。

This article analyzes the on-site application and force verification of the temporary cross passage reserved by the bracket based on the implementation of a cross intersection cast-in-place box beam in a certain reconstruction project.It elaborates on the structural component layout method selected for the Berey frame+steel pipe column form channel door opening to verify and analyze the stability of the bracket system construction.This ensures safety,reliability,economic feasibility,and comprehensively guarantees the cross construction,meeting the social effects brought by traffic.
