新厂房角柱、托梁及其在旧厂房上的支座设计

DESIGN OF CORNER COLUMN,JOIST AND SUPPORT ON THE EXISTING MAIN FACTORY BUILDING FOR A NEW MAIN FACTORY BUILDING

某新建主厂房与已经建成投产的旧有主厂房毗邻。新建主厂房有一根角柱被已经建成的两座辅助房屋夹在中间,无法设置。就新建主厂房缺下角柱的排架计算单元、上角柱的设置、托梁与旧有主厂房的连接和节点方案等问题进行了分析、比较,选择了一个利用旧有主厂房边柱支承新建主厂房上角柱、并能满足现行国家规范要求、构造简单、便于施工、安全合理的托梁及其支座。

A new main factory building is adjacent to the existing main factory building. A comer column of the new main factory building located among two existing auxiliary buildings is unable to be set. The analysis and comparison are made to solve the problems, including calculation unit of the bent frame without low-comer column, setting of the up-corner column, connection schemes between existing building and joists, etc. According to the above result, a better scheme is selected to make use of the side column of existed building to support the new up-corner column. This scheme can meet the commands of current national codes. In this scheme, the joists and supports are designed as simple-structure which is convenient for construction, safe and reasonable.
