  碗扣脚手架的基本要求七星彩走势图:其宽度应满足工人操作、材料堆放和运输的要求,坚固稳定,装拆方便,能多次周转使用.


  碗扣脚手架结构主要指作业层、横向构架和纵向构架三部分.作业层是直接承受施工荷载,荷载由脚手板传给小横杆,再传给大横杆和立柱.横向构架由立杆和小横杆组成,是碗扣脚手架直接承受和传递垂直荷载的部分,它是碗扣脚手架的受力主体.纵向构架主要是提高碗扣脚手架的整体稳定性.

  碗扣脚手架七星彩走势图由横杆、立杆组成.采用承插式的工作方式,相对于扣件式钢管脚手架拆装方便、便于运输、承受力大、安全性高.造价比扣件式钢管脚手架高,所以国内只有桥梁、地下室等对承受力有要求的工程项目中使用.房建大都采用扣件式钢管脚手架.


  碗扣脚手架的原理七星彩走势图:碗扣接头是碗扣脚手架的核心部件,它由上碗扣、下碗扣、横杆接头和上碗扣的限位销等组成,它可以同时连接四根横杆.钢管架的立杆和顶杆上每隔600mm设置一副碗扣接头.下碗扣和限位销直接焊在立杆或顶杆上.当上碗扣的缺口对准限位销时,上碗扣可沿立杆向上滑动一段距离,横杆接头随即可插入下碗扣带齿的齿碗内,将上碗扣沿限位销重新滑下扣住横杆接头,并顺时针旋转扣紧.


  碗扣脚手架的规格:碗扣脚手架分为横杆和立杆.常用的横杆规格为:HG-150,HG-120,HG-90,HG-60常用的立杆规格为:LG-300,LG-240,LG-180,LG-150,LG-120,LG-90,LG-60.
