Recycled concrete T-shaped steel pipe special-shaped column
The invention discloses a recycled concrete T-shaped steel pipe special-shaped column, and relates to the field of recycled concrete T-shaped steel pipe special-shaped columns. According to the recycled concrete T-shaped steel pipe special-shaped column, a large-diameter steel pipe is employed on a T-shaped special-shaped column to confine recycled concrete, and the whole special-shaped column isconnected more tightly by a connecting rib in an L-shaped fastening steel plate, so that the overall anti-torsion capacity is improved, and the bearing capacity and the seismic resistance of the recycled concrete confined by the steel pipe are improved; longitudinal reinforcing ribs, transversal reinforcing ribs and stirrups are added into recycled aggregate concrete poured in a structure, so thatthe compressive strength and the tensile strength of the overall structure are enhanced; by installing protruding blocks, contact area between the recycled aggregate concrete and the surface of the circular steel pipe is increased, so that the L-shaped fastening steel plate is connected with the surface of the circular steel pipe more tightly through the recycled aggregate concrete, the compressive strength, the shearing strength and the tensile strength of the overall structure are enhanced, and the problem that the internal recycled concrete has microcracks under the action of pressure is effectively avoided; and the recycled concrete T-shaped steel pipe special-shaped column has a certain application prospect.
本发明公开了一种再生混凝土T型钢管异形柱，涉及再生混凝土T型钢管异形柱领域。本发明在T型异形柱采用大直径的钢管约束再生混凝土，以及通过L型紧固钢板内部的连接筋使整个异形柱连接更为紧密，提高了整体的抗扭转能力，并提高了受钢管约束的再生混凝土的承载力和抗震性，在结构浇筑的再生骨料混凝土中增加纵向加强筋、横向加强筋与箍筋，增强了整体结构的抗压抗拉强度，设置的凸出块增加了再生骨料混凝土与圆形钢管表面的接触面积，使的L型紧固钢板通过再生骨料混凝土与圆形钢管表面连接更加紧固，增加了整体结构的抗压抗剪抗拉强度，有效的防止了内部再生混凝土在压力作用下出现微裂纹的问题，具备一定的使用前景。
