Adjustable spherical joint of rib ring type cable dome structure
The invention discloses an adjustable spherical joint of a rib ring type cable dome structure. The spherical joint consists of a spherical shell center body, a guide rail type lug plate, and a conicaljoint conversion element; a hole matched with the guide rail type lug plate in shape is formed in the surface of the spherical shell center body; the guide rail type lug plate is provided with a pinhole for being connected with a tension element; the guide rail type lug plate is clamped into a clamping groove of the spherical shell center body through 90-degree rotation and is fixed through a guide rail attached to the inner circle of a spherical shell; the bottom end of the spherical shell adopts a plane design and can be connected with the conical joint conversion element; and a slotted hole with a thread is formed in the lower surface of the conical joint conversion element for being connected with a pressed element. According to the adjustable spherical joint of the rib ring type cable dome structure, on the premise that the stress performance is guaranteed, different combinations of the different clamping grooves and the guide rail type lug plates provide a plurality of angle free combination modes for the joint, so that the adjustable performance of the joint is achieved, and the hollow spherical shell design reduces the dead weight and the assembly error of the joint.
本发明公开了一种肋环型索穹顶结构可调节式球形节点；它由球壳中心体、导轨式耳板、锥形接头转换构件组成；球壳中心体表面上开有与导轨式耳板形状匹配的孔洞；导轨式耳板上开有销孔供受拉构件连接使用；导轨式耳板通过90°旋转卡入球壳中心体的卡槽，利用与球壳内圆相贴合的导轨进行固定；球壳底端选用平面设计，可与锥形接头转换构件进行连接；锥形接头转换构件下表面开有带螺纹的槽孔供受压构件连接使用；本发明提供的肋环型索穹顶结构可调节式球形节点在保证受力性能的前提下，不同卡槽与导轨式耳板的不同组合为节点提供了多种角度自由组合方式，实现了节点调节的可性能；镂空球壳形设计减小了节点自重和装配误差。
