PK segmental beam high-altitude prefabricated support structure and method for carrying out sliding construction through PK segmental beam high-altitude prefabricated support structure
The invention discloses a PK segmental beam high-altitude prefabricated support structure and a method for carrying out sliding construction through the PK segmental beam high-altitude prefabricated support structure. The PK segmental beam high-altitude prefabricated support structure comprises side box support systems and a bilateral inter-box support system, and the side box support systems are arranged on the two sides of the bilateral inter-box support system; the side box support system comprises a side box pile foundation, a side box bearing platform, a side box steel pipe stand column supporting structure, a side box steel mold supporting structure and a side box steel mold structure, and the side box steel mold supporting structure is connected with a side box steel mold supporting structure sliding rail. The bilateral inter-box support system comprises a middle pile foundation, a middle bearing platform, a middle steel pipe stand column supporting structure and a middle area formwork supporting frame body, the middle steel pipe stand column supporting structure comprises an upper frame body and a lower frame body, and the two sides of the upper frame body are connected with the inner sides of the side box steel pipe stand column supporting structures through telescopic jacks; a lifting adjusting device is arranged at the top of the lower frame body, and the lower frame body is arranged below the upper frame body in a sliding mode. The problems that when an existing ultra-wide PK type box girder is prefabricated through a high-altitude support method, demolding is difficult, and a girder body is prone to cracking are solved.
本发明公开了一种PK节段梁高空预制支架结构及用其进行滑移施工的方法，包括边箱支架系统和双边箱间支架系统，边箱支架系统设置在双边箱间支架系统两侧，边箱支架系统包括边箱桩基础、边箱承台、边箱钢管立柱支撑结构、边箱钢模支撑结构和边箱钢模结构，边箱钢模支撑结构与边箱钢模支撑结构滑移轨道相连，双边箱间支架系统包括中部桩基础、中部承台、中部钢管立柱支撑结构和中间区域模板支撑架体，中部钢管立柱支撑结构包括上架体和下架体，上架体两侧通过伸缩千斤顶与边箱钢管立柱支撑结构内侧相连，下架体的顶部设有升降调节装置，下架体滑动的设置在上架体下方。解决现有超宽PK型箱梁在采用高空支架法预制时存在脱模困难以及易导致梁体开裂的问题。
