议板式楼梯施工缝留置位置及处理方法

Discussion on the Position and Treatment of Construction Joint of Slab Staircase

结合工程实践经验,通过对楼梯板结构受力的分析确定楼梯施工缝位置,避免留置不当造成结构的危害。以某工程为例,阐述了现浇楼梯施工缝留置的方法、低温情况下混凝土板式楼梯施工缝的处理方式、以及楼梯板施工缝处支立模板的做法注意事项,旨在改善和提高混凝土板式楼梯的工程质量。

This article combines the practical experience of the project, through the analysis of the force of the stair structure to determine the position of the construction joints of the stairs to avoid the structural damage due to improper placement. An engineering case was used as an example to illustrate the method for retaining the construction joints of cast-in-situ staircases, the treatment methods for construction joints of concrete slab stairs at low temperatures, and the precautions for installing the formwork at the construction joints of the staircase slabs. It is hoped that the concrete slab staircases will be improved. Quality has improved.
