Bracket-free construction method for double-limb thin-wall high-pier tie beam
The invention discloses a double-limb thin-wall high pier tie beam support-free construction method which comprises the steps that after a creeping formwork climbs, the top elevation is located at thebottom elevation of the tie beam, the lower chamfer height of the tie beam is reduced, pier body concrete of the section is poured, and after the concrete reaches a certain strength, a hanging beam at the top of the creeping formwork is dismantled; a tie beam lower chamfer section formwork, a tie beam middle section formwork and a tie beam upper chamfer section formwork are installed respectively, then concrete is poured, and then the tie beam upper chamfer section, the tie beam middle section, the tie beam lower creeping formwork operation platform, the transverse bridge direction connectingbeam, the pier column formwork located on the transverse bridge direction side and the tie beam lower chamfer section formwork are dismantled in sequence. According to the method, the problem of repeated mounting and dismounting caused by the fact that all original pier body templates need to be dismounted during high pier tie beam construction is solved; the pier body construction system and thetie beam construction system achieve the fusion effect, no support is needed in the whole tie beam construction process, meanwhile, a formwork integrated platform in pier body construction is utilized, the effect is guaranteed, and the safety guarantee is greatly improved.
本发明专利公开了一种双肢薄壁高墩系梁无支架施工方法，包括步骤：爬模爬升后顶标高位于系梁底标高减系梁下倒角高度，浇筑本节段墩身混凝土、待混凝土达到一定强度，拆除爬模顶部悬挂梁，分别安装系梁下倒角段模板、系梁中段模板、系梁上倒角段模板，再浇筑混凝土，再依次拆除系梁上倒角段、系梁中段、位于系梁下爬模操作平台和横桥向连接梁、横桥向侧的墩柱模板、系梁下倒角段模板；本发明解决了高墩系梁施工时需全部拆除原有墩身模板，造成反复安拆的问题；墩身、系梁两个施工体系达到融合效果，系梁施工整体过程中无需任何支架，同时利用墩身施工中的模板一体平台，及保证了功效，又大大提高了安全保障。
