Concrete-filled steel tube structure, pouring method, concrete material and building
The invention provides a concrete-filled steel tube structure, a pouring method, a concrete material and a building, and relates to the technical field of buildings. The concrete-filled steel tube structure comprises an outer tube body, an inner tube body, a first filling body and a second filling body, the outer diameter of the inner pipe body is smaller than the inner diameter of the outer pipe body, and the inner pipe body is sleeved with the outer pipe body. The first filling body is located in the inner pipe body, and the second filling body is located between the inner pipe body and the outer pipe body. And the first filling body and the second filling body are formed by pouring concrete materials. According to the concrete-filled steel tube structure, the filling body is good in crack resistance and shrinkage resistance, the overall stability can be improved, the bearing capacity of a tubular column is improved, the defect of stress concentration is overcome, and therefore the local buckling resistance of the tubular column is further improved.
本公开提供了一种钢管混凝土结构、浇筑方法、混凝土材料及建筑物，涉及建筑技术领域。钢管混凝土结构包括：外管体、内管体、第一填充体和第二填充体；内管体的外径小于外管体的内径，内管体套设于外管体内；第一填充体位于内管体内，第二填充体位于内管体和外管体之间；第一填充体和第二填充体采用混凝土材料浇筑形成。本公开的钢管混凝土结构，填充体的抗裂能力、抗收缩能力好，能够提高整体稳定性，改善管柱的承载能力，克服应力集中的缺陷，从而进一步提升管柱的局部抗屈曲性能。
