Bidirectional ribbed multi-cavity concrete-filled steel tube pier and framework and construction method thereof
The invention aims to provide a bidirectional ribbed multi-cavity concrete-filled steel tube pier and a framework and a construction method thereof. High strength advantage is achieved, according to the technical scheme, a central pipe column and outer pipes surrounding the central pipe column are comprised, wherein two adjacent outer pipes are arranged at an interval, a rib plate is arranged at the interval between each two adjacent outer pipes; it is characterized in that each rib plate comprises a base plate and flanges led out from the base plate, the rib plates are divided into one-way rib plates and two-way rib plates, and second welding seams are arranged among the outer pipes, the one-way rib plates and the two-way rib plates. The constraint effect on core concrete can be enhancedthrough the inner and outer bidirectional ribs and the central steel pipe, the steel pipe disengagement phenomenon and the core concrete cracking phenomenon are reduced, the lateral resistance, bending resistance and seismic resistance of the pier are improved, and the corrosion resistance and durability are enhanced through an outer protection layer.
本发明的目的是提供一种双向带肋多腔钢管混凝土桥墩及其骨架、施工方法，具有高强度的优势，技术方案包括中心管柱、环绕于中心管柱四周的外管，相邻两外管之间间距设置，相邻两外管之间的间距处设有肋板，其特征在于，所述肋板均包括基板、从基板上引出的翼缘，肋板分为单向肋板和双向肋板，外管、单向肋板和双向肋板之间设有第二焊缝。本发明能够通过内外双向带肋和中心钢管增强对核心混凝土的约束作用，降低钢管脱开现象和核心混凝土开裂现象，提高桥墩抗侧、抗弯和抗震性能，通过外侧保护层增强耐腐蚀性能和耐久性能。
