Threaded obliquely-arranged ribbed steel tube concrete column and design method thereof
The invention relates to a threaded obliquely-arranged ribbed steel tube concrete column and a design method thereof. The threaded obliquely-arranged ribbed steel tube concrete column comprises a ribbed steel tube and concrete, the ribbed steel tube comprises a steel tube and a plurality of ribs fixed on the steel tube, the multiple ribs are fixed on the steel tube in a spiral ascending mode, andthe vertical distance between the adjacent ribs is 0.15-0.3 m. The design method comprises the following steps that the size and shape of the steel tube for engineering are determined, and the steel tube is manufactured; the ribs are produced according to the shape and the size of the steel tube, as for the circular steel tube, the length of the ribs is 20% of the diameter of the circular steel tube, and as for the rectangular steel tube, the length of the ribs is 20% of length of the rectangular short edges, and the width of the ribs is 50% of the length of the ribs; and the produced ribs arewelded to the inner wall of the steel tube in a spiral ascending mode. The problems that coarse aggregate is accumulated at the lower part due to too fast sinking of the coarse aggregate at the maintenance stage after concrete pouring is completed, the concrete segregation phenomenon is caused, consequently, the compactness of the concrete is affected, the strength of the concrete is reduced andthe steel tube concrete column cannot exert excellent performance are solved.
本发明为螺纹倾斜布置肋钢管混凝土柱及设计方法，包括带肋钢管和混凝土，所述带肋钢管包括钢管和固定在钢管上的多个肋，多个肋呈螺旋上升方式固定在钢管上，相邻肋的竖直距离为0.15‑0.3m。该设计方法包括以下内容：确定工程采用钢管的尺寸及形状，制作成钢管；根据钢管的形状及尺寸生产肋，对于圆形钢管，肋的长度取圆形钢管直径的20％，对于矩形钢管则取矩形短边长度的20％；肋的宽度取肋长度的50％；将生产的肋按照螺旋上升方式焊接在钢管内壁。解决了由于在混凝土浇筑完成后养护阶段粗骨料的过快下沉会形成下部粗骨料积聚，导致混凝土离析现象的产生，从而影响混凝土的密实度，造成混凝土的强度降低、钢管混凝土柱发挥不了优良性能的问题。
