Fully-prefabricated concrete-filled steel tube vertical connection joint, row concrete-filled steel tube structure and construction method
The invention relates to a full-prefabricated assembly type steel pipe concrete vertical connection joint, a row steel pipe concrete structure and a construction method. The connection node comprises: an upper concrete filled steel tube; the upper connecting section is arranged at the bottom of the upper steel pipe concrete in an annular shrinkage mode, the upper connecting section and the upper steel pipe concrete are integrally poured, and at least one annular inserting groove is formed in the side wall of the upper connecting section; the lower steel pipe concrete is arranged below the upper steel pipe concrete; the lower connecting section is annularly expanded and arranged at the top of the lower steel pipe concrete, a vertical inserting part is arranged between the lower connecting section and the top of the lower steel pipe concrete, the upper connecting section and at least part of the upper steel pipe concrete are inserted into the vertical inserting part, an annular gap is reserved between the upper connecting section and the lower connecting section, and the annular gap communicates with the vertical inserting part; a plurality of inserting holes are formed in the side wall of the lower connecting section in the radial direction corresponding to the annular inserting grooves; the plurality of plugging keys are matched with the plurality of plugging holes and are suitable for being plugged and fixed to the annular plugging groove through the plugging holes; and the grouting material is suitable for being poured into the annular inserting groove and the vertical inserting part through the annular gap. Internal force is transmitted between the upper concrete filled steel tube and the lower concrete filled steel tube in an inserting key and anchoring connection mode, welding construction is not needed, and therefore the defect that prefabricated concrete in the steel tubes is damaged by welding high heat is overcome, operation is easy, labor can be greatly saved, and production efficiency is improved.
本发明涉及一种全预制装配式钢管混凝土竖向连接节点、排钢管混凝土结构及施工方法。该连接节点包括：上钢管混凝土；上连接段，环向收缩设置在上钢管混凝土的底部，与上钢管混凝土一体浇筑，上连接段的侧壁设有至少一道环向插接槽；下钢管混凝土，设置在上钢管混凝土的下方；下连接段，环向扩大设在下钢管混凝土的顶部，与下钢管混凝土的顶部之间具有竖向插接部，上连接段以及至少部分上钢管混凝土插接至竖向插接部，与下连接段之间预留有环向空隙，环向空隙与竖向插接部连通，并且下连接段的侧壁对应环向插接槽径向开设有多个插接孔；插接键，设有多个，与多个插接孔相匹配，适于通过插接孔插接固定至环向插接槽；灌浆料，适于通过环向空隙灌注至环向插接槽和竖向插接部。本发明采用插接键+锚固连接方式在上、下钢管混凝土之间传递内力，不再焊接施工，从而解决焊接高热量损伤钢管内预制混凝土的缺陷，易于操作，能够大量节省劳动力、提高生产效率。
