无锡交校图书室加固设计与施工

The reinforcement design and construction of a school library

我校图书室由原教学楼改造而成,因设计荷载变化,故对原教学楼进行加固。在加固设计时,楼面板采用面层现浇及碳布增强其强度,采用附加梁减小楼面板跨度并传递楼面板新增荷载,KJ-1框架梁采用增大截面技术以满足承载要求,而结构柱则采用外包型钢加固技术来满足竖向荷载的要求。同时,对不同加固技术的施工要点进行了简要阐述。通过各种加固技术的综合应用,为今后学校老旧建筑物的改造加固探索一种简便而可行的方法。

Our school library is transformed by the teaching building. Because the design load is changing, the teaching building must be reinforced. While making the reinforcement design ,the means of surface cast-in-situ and carbon cloth are applied to strengthen the floor plates;the additional beam is applied to reduce the span of floor plates and to transmit the new load of the floor plates; the technology of magnifying cross section is applied to fulfill the request of the load of the frame beam; and the reinforcement technology of wrapping pillar with steel is applied to satisfy the request of the vertical load of the structural column. Meanwhile this paper briefly states the construction points of different reinforcement technology. Through the comprehensive application of reinforcement technology, we will explore a simple and feasible reinforcement method for the transformation of schools＇ old buildings in the future.
