［摘要］天府國際會議中心項目前廳檐廊在傳統榫卯結構基礎上進行創新，采用鋼木混合榫卯結構技術。木結構采用CLT（交錯層壓木材）技術制造的膠合木，受力變形有保障，耐火性優異。工程全過程采用CADWork軟件進行建模，對各復雜節點提供可視化指導，在保證工程建設進度的同時減少返工。由于膠合木安裝高度較大，質量控制存在困難，因此采用屋面分段吊裝+高空拼裝固定的方式進行施工，降低施工難度，同時有效控制質量和施工進度。

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
