[摘要]天府国际会议中心项目前厅檐廊在传统榫卯结构基础上进行创新,采用钢木混合榫卯结构技术。木结构采用CLT(交错层压木材)技术制造的胶合木,受力变形有保障,耐火性优异。工程全过程采用CADWork软件进行建模,对各复杂节点提供可视化指导,在保证工程建设进度的同时减少返工。由于胶合木安装高度较大,质量控制存在困难,因此采用屋面分段吊装+高空拼装固定的方式进行施工,降低施工难度,同时有效控制质量和施工进度。

Abstract:The front hall of the Tianfu International Conference Center project is innovated on the basis of the traditional tenon and mortise structure, using steel wood mixed tenon and mortise structure technology. The wooden structure adopts the glulam made of CLT technology, which is guaranteed to be deformed under stress and has excellent fire resistance. The whole process of the project is modeled by CADWork software to provide visual guidance for each complex node, which can reduce rework while ensuring the progress of the project. Due to the high installation height of glulam and the difficulty in quality control, the method of roof segmental hoisting + high altitude assembling and fixing is adopted to reduce the difficulty of construction, while effectively controlling factors such as quality and construction progress.

Keywords:steel wood mixed; tenon and mortise; eaves gallery; hoisting; CLT technology
