Concrete-filled steel tube composite structure made of coal gangue sand
The invention discloses a concrete filled steel tube composite structure made of coal gangue sand, and relates to the technical field of building structures and the technical field of concrete. The concrete-filled steel tube composite structure made of the coal gangue sand comprises a cylindrical steel tube and concrete made of the coal gangue sand, the inner side of the steel tube is fixedly connected with a T-shaped connecting steel plate and an annular steel rib stiffener arranged in the steel tube, and the concrete is poured into the steel tube and the annular steel rib stiffener; the annular steel rib stiffener comprises a plurality of annular plates distributed in the length direction of the steel pipe, and the annular plates are fixedly connected through arc-shaped steel sheets extending in the length direction of the steel pipe. And a plurality of arc-shaped steel sheets are arranged. The invention provides a concrete-filled steel tube column made of coal gangue sand, the steel tube coal gangue concrete is made of mineral waste coal gangue to make up the defects of the concrete caused by replacing natural fine aggregate with mineral waste, and the problem that the natural fine aggregate of the concrete is increasingly in shortage is relieved while the working performance of a component is met; and meanwhile, by utilizing the double constraint effects of the externally-wrapped steel pipe, the internally-arranged annular steel rib stiffeners and the T-shaped steel plates on the core concrete, the strength and peak strain of the concrete are further improved, and the axial compression bearing capacity and ductility of the concrete column are improved.
本发明公开了一种煤矸砂制作钢管混凝土组合结构，涉及建筑用结构技术领域、混凝土技术领域。该煤矸砂制作钢管混凝土组合结构，包括圆柱状钢管、煤矸砂制作混凝土、钢管的内侧固定连接有T型连接钢板以及设置在所述钢管内的环状钢骨加劲件，所述钢管以及环状钢骨加劲件内部浇筑有混凝土；所述环状钢骨加劲件包括沿钢管长度方向分布的多个环向板，多个环向板通过沿钢管长度方向延伸的弧形钢片固定连接；所述弧形钢片设有多个。本发明提供一种煤矸砂制作钢管混凝土柱，利用矿产废物煤矸石制作钢管煤矸砂混凝土来弥补因矿物废料替代天然细骨料而导致混凝土自身缺陷，在满足构件工作性能的同时，缓解混凝土天然细骨料日益短缺问题；同时利用外包钢管及内配环状钢骨加劲件、T型钢板对核心混凝土的双重约束作用，进一步提高混凝土的强度和峰值应变，以及提高混凝土柱的轴压承载力和延性。
