烟囱、水塔砌筑所用的木引尺,使用时侧向稳定性差,摆动大,挠度也大,对中比较困难。标尺杆与架杆之间有高度差(木架杆一般高160mm 左右),在每次测量校正时都存在比较大的偏差。既影响施工质量,也给施工人员操作带来一定的难度。我们在施工30m 高砖砌水塔过程中,将木引尺改制成钢木引尺,即将木引尺架改为 Chimes and water tower masonry are used with wooden rulers that have poor lateral stability, large swings, and large deflections, making them difficult to center. There is a height difference between the rod and the rod (the rod is generally 160 mm high), and there is a large deviation in each measurement correction. It not only affects the construction quality, but also brings certain difficulties to the construction personnel. During the construction of a 30m high brick water tower, we changed the wooden lead to a steel wood lead, that is, to change the wooden lead frame to
