北京人遗址保护工程单层空间网格施工技术

The Single-layer Spatial Grid Construction Technology of Beijing Ren Ruins Protection Project

周口店北京人遗址保护棚为大跨度变曲率空间网格结构,造型复杂,纵向投影距离为76m。通过对施工前模拟计算、加工过程中的精度控制、安装过程中合理的施工顺序和卸载顺序的研究,将结构变形控制在允许范围内,取得较好效果。消防、防震等措施的有效实施有利于施工过程中的文物保护。

The protection shed of Zhoukoudian Beijing Ren Ruins is a large-span space grid structure with variable curvature. Its shape is complex and its vertical projection distance is 76 m. By researching the simulation calculation before construction, the precision control during processing, the reasonable construction sequence and unloading sequence during installation,the structural deformation is controlled within the allowable range,and good results are obtained. The effective implementation of fire prevention and earthquake prevention measures is conducive to the protection of cultural relics in construction process.
