折线形梯段在图纸上,只有上水平距离尺寸,没有下水平距离尺寸,确实给施工人员带来了一些复杂问题。下水平距离的尺寸,虽然能用简单的方法计算出来。但对于在现场工作的工人来说,还是不太方便。根据我的实践经验,在木工配制模板时。如使用“差距角”。直接在模板上划出上、下水平的差距,比使用计算的方法,更为简便易行。“差距角”就是上水平距离与 On the drawing, only the horizontal distance dimension, no horizontal distance dimension, has caused the construction staff some complicated problems. The size of the lower horizontal distance can be calculated by a simple method. However, it is still inconvenient for workers who work on site. According to my practical experience, when the carpentry prepares the template. Use “gap angle”. It is easier and more convenient to use the calculation method to draw the gap between the top and bottom levels directly on the template. “Gap angle” is the distance and
