西安市西京医院制剂楼一层⑦—⑧轴、(?)—(?)轴间有一旋转楼梯,旋转角度为135°,水平投影面积为17.2米~2。见图1。如采用通常的木模施工,需用木材2.38米~2,而且是一次投入,无法周转。工地施工人员根据现场条件和职工技术情况,经多次讨论,提出钢模板附加砖胎模的施工方案。具体方案如下。一、旋转楼梯为两跑楼梯,中间有一扇形休息平台:从-0.030米至+
There is a spiral staircase between the 7-8 axis and (?)-(?) axis on the first floor of the preparation building of Xijing Hospital in Xi’an. The rotation angle is 135°, and the horizontal projection area is 17.2 meters-2. see picture 1. If the usual wood mold construction is used, wood 2.38 m~2 must be used, and it is a one-time investment and cannot be turned around. The construction site construction personnel have discussed several times based on the site conditions and the technical conditions of the employees, and put forward the construction plan of the steel formwork with the addition of brick molds. The specific plan is as follows. First, the spiral staircase is a two-run staircase with a fan-shaped rest platform in the middle: from -0.030 meters to +
