Construction method for layered lifting of large-span open-web corridor steel platform
The invention relates to a construction method for layered lifting of a large-span open-web corridor steel platform, and belongs to the technical field of building steel structure installation and construction. The problems that when a multi-layer large-span corridor between high-rise buildings is constructed, the corridor steel platform needs to be hoisted layer by layer, hoisting is conducted from bottom to top through a traditional method, the requirement for a construction site is large, and the requirement for the station position of hoisting device is met are solved. The problem that the safety is poor due to the fact that an upper-layer steel platform is assembled on the basis of a lower-layer steel platform and then hoisting operation is conducted, but the construction face is insufficient is solved. According to the steel platform lifting construction method, main beam brackets are installed on the buildings on the two sides to serve as pre-installation pieces, and the lengths of the main beam brackets are decreased layer by layer from top to bottom; the lengths of main beams of the steel platform are increased layer by layer from top to bottom; and the open-web corridor steel platform is integrally assembled on the ground, and then layered lifting installation is conducted from top to bottom. Compared with a traditional construction scheme, reverse operation is achieved, construction is rapid, operation is easy, and the overall occupied area is small.
本申请涉及一种用于大跨度空腹连廊钢平台分层提升的施工方法，属于建筑钢结构安装施工技术领域。为解决高层建筑间多层大跨度连廊施工时，需要逐层吊装连廊钢平台，利用传统方法从下往上进行吊装，对于施工场地要求大，以解决吊装设备站位需要。通过在下层钢平台基础上拼装上层钢平台再进行吊装作业，但又存着施工面不足导致安全性差的问题。本申请提供的钢平台提升施工方法，通过在两侧建筑物上安装主梁牛腿作为预安装件，且主梁牛腿长度从上至下逐层减短设置；将钢平台主梁长度从上至下逐层增加设置；在地面进行空腹连廊钢平台整体拼装，再从上至下分层提升安装。相比传统施工方案，属于逆向操作，施工快速，操作简单，整体占地小。
