Embedded rigid connection steel pipe concrete column base joint
The invention discloses an embedded rigid connection steel pipe concrete column base joint, and relates to the technical field of steel pipe concrete embedded rigid connection column base joints. The embedded rigid connection steel pipe concrete column base joint comprises a lower-layer steel bottom plate and a steel pipe column outer wall steel plate lower section and an upper-layer steel bottom plate. The lower-layer steel bottom plate is embedded in a bottom structure and located on the upper portion of non-shrinkage fine stone concrete, the steel pipe column outer wall steel plate lower section is vertically welded to the upper portion of the lower-layer steel bottom plate, and the upper-layer steel bottom plate is welded to the upper end of the steel pipe column outer wall steel plate lower section. Column inner studs are welded to the inner side of the steel pipe column outer wall steel plate lower section, column outer studs are welded to the outer side of the steel pipe column outer wall steel plate lower section, lower-layer steel bottom plate outer side positive stiffening ribs are welded between the steel pipe column outer wall steel plate lower section and the lower-layer steel bottom plate, and upper-layer steel bottom plate outer side inverted stiffening ribs are welded between the upper portion of the steel pipe column outer wall steel plate lower section and the upper-layer steel bottom plate. According to the embedded rigid connection steel pipe concrete column base joint, more concrete and steel bars are saved, the stress is reliable, the construction is convenient, and the on-site construction progress is accelerated; meanwhile, the joint can also reduce hydration heat of mass concrete, so that the safety of a foundation is ensured to a certain extent; and moreover, the cost of on-site excavation and earthwork transportation is reduced, the depth of a foundation pit is reduced, and the foundation pit support cost is reduced.
本发明公开了一种埋入式刚接钢管混凝土柱脚节点，涉及钢管混凝土埋入式刚接柱脚节点技术领域。本发明包括埋入底部结构内且位于无收缩细石砼上部的下层钢底板、竖直焊接于下层钢底板上部的钢管柱外壁钢板下段、焊接于钢管柱外壁钢板下段上端的上层钢底板；钢管柱外壁钢板下段内侧焊接有柱内栓钉，外侧焊接有柱外栓钉，钢管柱外壁钢板下段下部与下层钢底板之间焊接有下层钢底板外侧正加劲肋，钢管柱外壁钢板下段上部与上层钢底板之间焊接有上层钢底板外侧倒加劲肋。本发明节省较多混凝土和钢筋的用量，受力可靠，施工方便，加快了现场施工进度；同时节点还能够降低大体量混凝土的水化热，在一定程度上保证了基础的安全；并且，减少了现场开挖和运输土方的费用，且减小了基坑深度，减少了基坑围护费用。
