Novel composite constraint square steel tube concrete column
The invention discloses a novel composite constraint square steel tube concrete column, and relates to the field of assembling type constructional engineering. The novel composite constraint square steel tube concrete column comprises a reinforcement cage, a square steel tube, stiffening ribs and core concrete, wherein four inner walls of the square steel tube are independently welded with the stiffening rib; the square reinforcement cage is arranged in the square steel tube; four longitudinal ribs of the reinforcement cage are independently connected with four stiffening ribs; and the core concrete is poured in the square steel tube. The square steel tube and square stirrups perform a composite constraint effect on the core concrete, large confining pressure is provided, the core concreteis under a three-directional stress state, the compression bearing capacity of the concrete is increased, and the brittle failure of the concrete is delayed. In addition, requirements, including goodeconomic efficiency, a simple production technology, convenience in construction and installation and the like, can be met, and the novel composite constraint square steel tube concrete column can bewidely applied to an assembling type structural system.
本发明公开了一种新型复合约束方钢管混凝土柱，涉及装配式建筑工程领域。一种新型复合约束方钢管混凝土柱，包括钢筋笼、方钢管、加劲肋和核心混凝土。方钢管的四个内壁上均焊接有加劲肋，所述方钢管内设置有方形的钢筋笼，钢筋笼的四根纵筋分别与四个加劲肋连接，方钢管内浇筑有核心混凝土。本发明的方钢管和方箍筋对核心混凝土起到复合约束效果，提供了较大的围压，使核心混凝土处于三向受力状态，增大了混凝土抗压承载力，并延缓了混凝土的脆性破坏。且本发明满足了经济型好、生产工艺简单、便于施工安装等要求，可广泛的应用在装配式结构体系中。
