悬挑脚手架工作性能试验研究

Experimental study on suspended scaffold

以郑州某实际工程为试验背景,将力传感器分别安装在悬挑脚手架锚固端和斜拉钢丝绳中,并随施工进展连续监测各监测点位置处内力发展过程。试验发现,正常设计的悬挑型钢锚固端内力(单道)和斜拉索内力均在5 k N以下,而在悬挑长度大于锚固长度的转角部位,型钢锚固端内力可达16 k N。

Some monitoring sensors are employed in the suspended scaffold to determine the development course of internal forces,such as the force in the suspending wire and the anchorage of cantilever beam. The results of the monitoring show that for the normal designed suspended scaffold,the internal forces in the wire and anchorage are no more than 5 kN,however,when the cantilever segment is longer than the anchorage segment,the anchorage force may be 16 kN.
