低合金钢管在土建施工中的适应性试验研究

Experimental Research on Adaptability of Low-alloyed Steel Tube in Construction

对低合金钢管作脚手架和模板支撑架的适应性作了一系列对比试验，经过分析得出在土建施工中使用低合金钢管时，可锻铸铁扣件对其扣接能力无影响、搭设外脚手架的高度比普碳钢管架的限值降低２５％ 及搭设排架在以往经验尺寸上减小２０％ 等５

Analyzing a series of compare and contrast experiments on the adaptability of the low\|alloyed steel tube used in scaffold and bearing\|rack of formwork,we can draw five conclusions.For example,when low\|alloyed steel tube is used in construction,the fastening ability of forging fasteners is equal to that of a normal one,the height of the outside scaffold is 25% lower than the maximum value of normal steel tube,and the size of framework is 20% smaller than the usual ones and so on.
