Fabricated type concrete-filled steel tube column based on mortise-tenon connection
The invention discloses a fabricated type concrete-filled steel tube column based on mortise-tenon connection. The fabricated type concrete-filled steel tube column comprises a reinforced concrete support, a concrete column and a steel tube. The reinforced concrete support comprises a rectangular groove, an annular mortise is further formed in the side wall of the periphery of the rectangular groove, and a cross-shaped tenon is arranged in the rectangular groove. A cross-shaped mortise connected with the cross-shaped tenon in a matched mode is formed in the bottom of the concrete column, the concrete column is placed in the rectangular groove of the reinforced concrete support, and the cross-shaped tenon in the rectangular groove is embedded into the cross-shaped mortise in the bottom of the concrete column. The steel tube is a hollow rectangular cavity, the concrete column is sleeved with the steel tube, and the lower end of the steel tube is embedded into the annular mortise of the reinforced concrete support. Compared with a concrete-filled steel tube column obtained in a cast-in-place mode, the concrete-filled steel tube column is convenient to install, and the problems that the construction period is long because of the casting mode, and the structural mechanical property is unstable due to condition constraints in the construction process are solved.
本发明公开了一种基于榫卯连接的装配式钢管混凝土柱，包括钢筋混凝土支座、混凝土柱和钢管；所述钢筋混凝土支座包括矩形凹槽，所述矩形凹槽外围的侧壁上还设有环形榫槽，矩形凹槽中设有十字型榫头；所述混凝土柱底部设有与十字型榫头相配合连接的十字型榫槽；所述混凝土柱放置在钢筋混凝土支座的矩形凹槽中，矩形凹槽中的十字型榫头嵌入混凝土柱底部的十字型榫槽中；所述钢管呈中空矩形腔体，所述钢管套设在混凝土柱外且钢管下端部嵌入钢筋混凝土支座的环形榫槽中。相比于现场浇筑方式得到的钢管混凝土柱，本发明钢管混凝土柱安装方便，解决了浇筑方式带来的施工工期长和施工过程中受条件制约引起的结构力学性能不稳定的问题。
