Large-span underground structure externally-wrapped U-shaped steel reinforced concrete beam and manufacturing method thereof
The invention provides a novel large-span underground structure externally-wrapped U-shaped steel reinforced concrete beam and a manufacturing method thereof. The concrete beam structurally comprises a concrete beam body, U-shaped section steel, shear connectors and steel bars; the U-shaped section steel is externally wrapped outside the concrete beam and located on the lower middle side of the concrete beam; the shear connectors are welded to the inner side of the U-shaped section steel and used for connecting the U-shaped section steel and the concrete beam and transmitting shear force; and a steel bar frame is arranged in the concrete beam and is not in contact with the U-shaped section steel and the shear connectors. The externally-wrapped U-shaped steel reinforced concrete beam structure can remarkably improve the tensile bending resistance of the beam, improve the bearing capacity of the structure and reduce the cross section size of the beam, can be widely applied to building structures, bridge structures and other engineering structures, and is particularly suitable for large-span underground structures with the large-load characteristic.
本发明提供一种新型大跨地下结构外包U型型钢混凝土梁及其制作方法，混凝土梁结构包括混凝土梁本体、U型型钢、抗剪连接件和钢筋，所述U型型钢外包于混凝土梁外，位于混凝土梁中下侧；抗剪连接件焊接于U型型钢内侧，用于U型型钢和混凝土梁之间的连接，并传递剪力；钢筋架设于混凝土梁内，与U型型钢、抗剪连接件无接触。本外包U型型钢混凝土梁结构能显著提升梁的抗拉弯性能，提高结构承载力，减小梁截面尺寸，可广泛应用于建筑结构、桥梁结构及其它工程结构中，特别适用于具有大荷载特点的大跨地下结构。
