仿古建筑琵琶科节点施工技术

Construction Technology of the Lute-type Joint of Pseudo-classic Architecture

高景山白鹤寺改扩建工程在混凝土框架结构上部安装琵琶科斗拱,采用琵琶料节点。以往古建筑中琵琶科主要以榫卯连接为主。由于现在的木材多为速生材,较软,在琵琶科节点中通过对拉螺杆进行加固。详细介绍了琵琶科节点施工方案的选择,榫卯加螺杆双重连接节点设计、加固方法及施工技术。

In the retrofitting project of Baihe Temple in Gaojingshan Mountain,the lute-type joint is used to connect the PC frame structure and the upper structure. In ancient buildings,the lute-type joints is often to be connected by mortise and tenon. But because the modern wood is usual soft,the lute-type joints need to be strengthened by screw. In this article,the authors introduce in detail the selection of construction schemes,joint design of double connection of mortise and screw,strengthening method and construction technology of the lute-type joint.
