Concrete filled steel tubular column connecting structure and checking calculation and construction method
The invention discloses a concrete filled steel tubular column connecting structure and a checking calculation and construction method. The concrete filled steel tubular column connecting structure comprises two steel tubes which are connected up and down, in-tube concrete, an outer steel connecting piece, outer slurry and a structural beam, the lower end of the upper steel pipe is fixedly connected with the upper end of the lower steel pipe; the outer steel connecting piece is located on the outer side of the steel pipe, corresponds to a to-be-installed structural beam and is fixedly connected with the steel pipe. The outer steel connecting piece comprises a transverse outer connecting steel plate and a vertical outer connecting steel plate; filling the steel pipe with concrete in the pipe; the transverse outer connecting steel plate comprises an upper transverse connecting steel plate and a lower transverse connecting steel plate; the outer slurry is filled between the upper transverse connecting steel plate and the lower transverse connecting steel plate and wraps the steel pipe. The structure has the advantages that the node area is high in bearing capacity and ductility, concrete shrinkage and creep are reduced, and disengaging of the lower portion of the inner partition plate is reduced.
一种钢管混凝土柱连接构造、验算及施工方法，包括有两个上下连接的钢管、管内混凝土、外钢连接件、外浆料、结构梁；上钢管的下端与下钢管的上端固定连接；外钢连接件位于钢管的外侧，与待安装的结构梁对应设置，与钢管固定连接；外钢连接件包括横向外连接钢板和竖向外连接钢板；管内混凝土填充钢管；横向外连接钢板包括上横向连接钢板和下横向连接钢板；外浆料填充在上横向连接钢板和下横向连接钢板之间，包裹钢管。本发明具有节点区承载力高、延性高，减少混凝土收缩徐变，减少内隔板下部脱空的优点。
