Hollow interlayer steel pipe joint connected through U-shaped inserting plates
The invention relates to a joint connecting structure design, in particular to a hollow interlayer steel pipe joint connected through U-shaped inserting plates. Comprising an outer-layer steel pipe, an inner-layer steel pipe and interlayer concrete, the inner-layer steel pipe is sleeved with the outer-layer steel pipe and is concentrically arranged, the interlayer concrete is arranged between the inner-layer steel pipe and the outer-layer steel pipe, a central annular plate is arranged on the pipe wall of the outer-layer steel pipe, and a branch pipe is connected with the central annular plate. And the stress performance is superior to the simple superposition of the performance of the two materials. The structure can give full play to and utilize the characteristics of steel and concrete materials, and achieves advantage complementation in performance. The double-layer concentric circular steel pipe is adopted for pouring concrete into the annular part between the two layers of steel pipes, the inner steel pipe is kept hollow, the dead weight of the column body is reduced through the hollow section, the requirements for stiffness and strength can be met, meanwhile, the steel pipe column has moderate lateral toughness, and is suitable for power transmission towers, ocean platforms, bridge structures and the like.
本发明涉及一种节点连接结构设计，具体为一种U型插板连接的中空夹层钢管节点；包括外层钢管、内层钢管和夹层混凝土，所述内层钢管套接在外层钢管内且为同心设置，所述内层钢管和外层钢管之间设有夹层混凝土，所述外层钢管的管壁上设有中央环板，支管与中央环板连接。其受力性能优于两种材料性能的简单叠加。这种结构能充分发挥和利用钢和混凝土材料的特点，在性能上达到优势互补。采用双层同心圆形钢管于两层钢管间环形部分灌注混凝土，但内钢管保持空心，利用中空的断面减轻柱体自重，并能满足劲度与强度需求，同时具有适度的侧向韧性，适用于输电塔、海洋平台及桥梁结构等。
