盖梁悬吊支架平台的设计及应用探讨OA
Design and Application of the Suspended Bracket Platform for the Cap Beam
为解决西非几内亚等资源匮乏地区在桥梁盖梁施工中面临的材料与设备限制问题,旨在设计一种安全可靠、经济适用且便于实施的盖梁支架方案,以替代落地支架、抱箍法及穿钢棒法等传统施工方法.以几内亚某运矿道路中桥为工程背景,提出一种悬吊型钢支架平台方案.该方案采用多根Ø32 mm圆钢悬吊于墩柱顶部,下部承载双拼工字钢主梁,主梁上布置密排工字钢分配梁,形成承重平台.按照规范对平台各杆件进行承载力及变形验算,并编制了平台搭拆施工工序和要点.实践证明,该悬吊支架平台灵活方便、搭设工艺简单、安全可靠,适合项目所在地资源匮乏的情况,可为类似地区桥梁盖梁施工提供参考.
To address the material and equipment constraints in the construction of bridge bent caps in resource-scarce regions of Guinea,West Africa,this paper aims to design a safe,reliable,cost-effective,and easily imple-mentable bent cap support scheme to replace traditional construction methods such as ground support brackets,hoop methods,and steel bar insertion methods.Taking a medium-sized bridge on a mining road in Guinea as the engineering context,a suspended steel platform scheme is proposed.In this scheme,multiple Ø32 mm round steel bars are suspended at the top of the pier columns and supported a double I-beam main girder at the lower section,on which closely spaced I-beam distribution girders to form a load-bearing platform.According to relevant stan-dards,the bearing capacity and deformation of each platform component are calculated,and the construction proce-dures and key points for the platform's assembly and disassembly are developed.Practice has proven that this sus-pended steel platform is flexible,convenient,simple construction,safe and reliable,making it suitable for re-source-scarce project locations and serving as a reference for bridge construction in similar regions.
