论现浇肋梁楼盖模板支撑架的水平杆步距设置

现浇混凝土梁板结构模板支撑体系在进行水平杆设置时,由于受到肋梁高度变化的影响,导致步距设置不均匀,应根据肋梁高度的具体情况进行步距的专项设计。该文就架体地基顶面有高差、梁截面高度不超过标准步距以及梁截面高度超过标准步距三种情况下的步距设置方法进行了探讨,给出了具体的对策,并给出了确保步距均匀、架体结构简单的优化方法。

Lift Height Setting of Horizontal Tube in Formwork Support in Cast-in-situ Beam-slab Floor

When setting the horizontal tube of cast-in-situ concrete beam slab formwork support system, beam height changing will cause uneven lift step, so a special design should be done in accordance with the specific height. The setting methods are discussed under three different conditions of foundation surface with height difference, beam section with height no more than standard lift step and that exceeding standard one, specific countermeasures are also presented, with optimization methods for even lift step and simple structure offered.
