Concrete-filled steel tube column
The invention discloses a concrete-filled steel tube column, and relates to the field of structural engineering. The concrete-filled steel tube column comprises a steel tube, concrete and stiffening ribs, wherein internal threads for mounting the stiffening ribs are formed in the inner wall of the steel tube; each stiffening rib is formed by fixedly connecting a stiffening plate and a side stiffening plate; the steel tube is filled with the concrete; external threads are formed in the outer side wall of each side stiffening plate; and a through hole is formed in each stiffening plate; the positions of the stiffening ribs can be adjusted along the internal threads. The internal threads improve the binding power of the steel tube and the concrete, and the stiffening plates can prevent relative slippage of the concrete, so that cracking of the concrete is effectively inhibited. The stiffening ribs are simple and convenient to mount, enhance the tightening effect of the steel tube and prevent buckling deformation of the steel tube; the critical force of the steel tube is improved, so that the bearing capacity of the steel tube is improved; and the diameter of the steel tube is prevented from being too large, the structural space is saved, and the debonding phenomenon of the steel tube and the concrete is prevented.
本发明公开了一种钢管混凝土柱，涉及结构工程领域，包括钢管、混凝土和加劲肋，钢管内壁设置有供加劲肋安装的内螺纹，加劲肋由加劲板和侧加强板固定连接组成，钢管内填充有混凝土。侧加强板外侧壁具有外螺纹，加劲板上具有通孔，加劲肋的位置可沿内螺纹调节。内螺纹提高了钢管与混凝土的粘结力，加劲板能防止混凝土的相对滑移，有效抑制了混凝土的开裂。加劲肋安装简便，加劲肋加强了钢管的紧箍作用，防止钢管的屈曲变形；提高了钢管的临界力，从而提高钢管的承载力；避免了钢管直径过大，节约结构空间，防止钢管与混凝土的脱黏现象。
