北京香格里饭店三层以上为标准层,其高层部的一部分柱子和底层柱子不在同一铅直线上。上部结构受力后,借助于三层(设备层)的三角形构架,将上部荷载力向两侧分散而传至下层柱子上(图1)。因此,三层构架的地板梁须承受很大的拉力。在施工期间,为保证工程正常进行,需了解其受力情况,即测定SRC梁的伸长量和裂纹宽度,此项工作一直进行到积层法施工结束,本文简述此项工作的使用工具及方法。
The Shangri-La Hotel, Beijing is a standard floor above the third floor, where some of the pillars and the bottom pillars are not on the same vertical line. After the upper structure is subjected to the force, the upper load force is dispersed to both sides and transmitted to the lower column by means of a triangular structure of three layers (apparatus layers) (Fig. 1). Therefore, the floor beams of a three-story structure must withstand a great deal of tension. During the construction period, in order to ensure the normal operation of the project, it is necessary to understand the stress conditions, that is, to determine the elongation and crack width of the SRC beam. This work has been carried out until the completion of the construction of the laminate method. This article describes the use of tools in this work. And methods.
