Cross-shaped steel concrete column stirrup constraint structure and manufacturing method

JIANG HAN / ZHAO XUEFEI

The invention relates to the technical field of building structure design and civil engineering construction, in particular to a cross-shaped steel concrete column stirrup constraint structure and a manufacturing method. The problems that in the prior art, when stirrups are configured, holes need to be formed in profile steel to form an effective constraint effect on concrete, and construction is complex are solved. The cross-shaped steel concrete column comprises cross-shaped steel arranged in the center of the cross-shaped steel concrete column, peripheral stirrups arranged on the peripheries in all cross sections of the cross-shaped steel concrete column, and longitudinal bars arranged between the cross-shaped steel and the peripheral stirrups and extending in the column height direction. Each cross section of the cross-shaped steel concrete column is further internally provided with an internal stirrup for restraining the longitudinal bars. The stirrups do not penetrate through the profile steel, construction is convenient, the aperture ratio of the cross-shaped steel is reduced, and the bearing capacity of the steel reinforced concrete column can be improved.

本发明涉及建筑结构设计与土建施工技术领域，具体涉及一种十字型钢混凝土柱箍筋约束结构及制作方法，旨在解决现有技术箍筋的配置往往需要在型钢上开孔以形成对混凝土的有效约束作用，施工较为复杂的问题，本发明中的十字型钢混凝土柱包括设于十字型钢混凝土柱中心的十字型钢，设于十字型钢混凝土柱各个横截面内的外围的外围箍筋，以及设于十字型钢和外围箍筋之间沿柱高方向延伸的纵筋；十字型钢混凝土柱的各个横截面内还设有对纵筋形成约束的内围箍筋。本发明中的箍筋不穿过型钢，施工方便，且减小了十字型钢的开孔率，能够提高型钢混凝土柱的承载力。
