Rectangular octagonal combined spiral hoop and reinforced concrete column applying same
The invention belongs to the technical field of structural engineering, and discloses a rectangular octagonal combined spiral hoop and a reinforced concrete column applying the same. According to thetechnical scheme, the rectangular octagonal combined spiral hoop is characterized in that a single steel bar is spirally and continuously machined to form multiple turns of stirrups, octagonal stirrups and rectangular stirrups are arranged at intervals in each turn, and the octagonal stirrups are formed after four corners of the rectangular stirrups are cut off. The concrete column takes the rectangular octagonal combined spiral hoop as a stirrup, and the number of main reinforcements on each side of the column is 4-7 under the condition that no tie short stirrup is additionally arranged. Thestress performance and the workability of a concrete column component are improved, and the application range of the concrete column component is widened under the condition of not supplementing additional tie short stirrups.
本发明属于结构工程技术领域的矩形八角形组合螺旋箍及其应用的钢筋混凝土柱，技术方案为：一种矩形八角形组合螺旋箍，单根钢筋螺旋式连续加工形成多匝箍筋，每匝由八角形箍筋和矩形箍筋间隔布置，八角形箍筋的形状为矩形箍筋的形状切除四角后形成的形状。混凝土柱以矩形八角形组合螺旋箍为箍筋，在不附加拉结短箍筋的情况下柱每边主筋为4至7根。其提升混凝土柱构件受力性能、易加工性能，以及拓宽了在不补充附加拉结短箍筋条件下的适用范围。
