Multi-cavity ribbed concrete-filled steel tube pier and construction method thereof
The invention discloses a multi-cavity ribbed concrete-filled steel tube pier and a construction method thereof. The multi-cavity ribbed concrete-filled steel tube pier comprises square outer steel tubes, concrete, outer ribbed steel plates, an inner rectangular large steel tube, first weld joints and second weld joints; the four square outer steel tubes are dispersed on the four sides of a rectangular outer frame at certain intervals respectively; each outer ribbed steel plate is formed by bending and welding two sides of a common steel plate; after being welded for a certain length, the outer ribbed steel plates are welded with the square outer steel tubes so as to form the rectangular outer frame; steel plate ribs face the inner side of the rectangular outer frame; the inner rectangularlarge steel tube is embedded into an inner rectangular frame formed by the square outer steel tubes; the first weld joints are located at the joints of the inner rectangular large steel tube and thesquare outer steel tubes; the second weld joints are located at the joints of two outer ribbed steel plates. As an internal space is large, few materials are consumed, and an engineering quantity is small; steel is dominantly is used, so that the weight of the multi-cavity ribbed concrete-filled steel tube pier is light, and the structural rigidity and strength of the multi-cavity ribbed concrete-filled steel tube pier are good; the cross section of the multi-cavity ribbed concrete-filled steel tube pier is in a rectangular multi-cavity shape; the modulus of the cross section of the multi-cavity ribbed concrete-filled steel tube pier is large; and anti-rollover and anti-seismic properties of the multi-cavity ribbed concrete-filled steel tube pier are excellent. The multi-cavity ribbed concrete-filled steel tube pier and the construction method thereof are mainly used for the fabricated pier construction industry.
本发明公开了一种多腔带肋钢管混凝土桥墩及其施工方法，包括方形外钢管和混凝土，外侧带肋钢板，内部矩形大钢管，第一焊缝和第二焊缝。方形外钢管按一定间距分散于矩形外框架四边，四角各有一个；外侧带肋钢板由普通钢板两边弯折互相焊接形成，焊接一定长度后和方形外钢管相互焊接形成矩形外框架，钢板肋朝向矩形内侧；内部矩形大钢管嵌于方形外钢管所形成的内矩形框架；第一焊缝位于内部矩形大钢管和方形外钢管连接处，第二焊缝位于两外侧带肋钢板连接处。由于内部空间大，耗材少，工程量小；主要材料为钢材，自重轻，结构刚度和强度较好；截面为矩形多腔状，截面模量大，抗侧翻、抗震性能优越。本发明主要用于装配式桥墩建设行业。
