Truss crossed K-shaped node structure and mounting method thereof
The invention discloses a truss crossed K-shaped node structure and a mounting method thereof, belongs to the technical field of trusses, and solves the problem that an existing truss node is not provided with a crossed structure. The device comprises a vertical rod, and two K-shaped upper beam structures and two lower chord beams are arranged at the upper end and the lower end of the vertical rod in a crossed mode respectively. Each upper beam structure comprises two inclined rods and an upper chord beam, and reinforcing supports which are used for adapting to thermal expansion and cold contraction of the upper beam structures and can resist shock and dissipate energy are further arranged at the connecting joints of the vertical rods. By means of the two K-shaped upper beam structures, the truss is provided with a cross structure to achieve corner change, seismic resistance and energy dissipation are achieved through the reinforcing supports, the strength of the cross structure is improved, the reinforcing supports can adaptively rotate or incline along with uneven expansion caused by heat and contraction caused by cold of the upper chord beams and the inclined rods, and the strength of the cross structure is improved. The upper beam structure is reinforced, and meanwhile the stand columns are prevented from being damaged due to stress concentration.
本发明公开了一种桁架交叉K字节点结构及其安装方法，属于桁架技术领域，解决了现有桁架节点自身没有交叉结构的问题；其包括立杆，立杆的上端和下端分别交叉设置有两个呈K型的上梁结构和两根下弦梁；每个上梁结构包括两根斜杆和上弦梁，立杆在连接节点处还设置有用于适应上梁结构热胀冷缩且能抗震消能的加固支座。本发明利用两个呈K型的上梁结构不仅使桁架自身具有交叉结构来实现转角改变，并通过加固支座抗震消能，提高交叉结构的强度，且加固支座能够随着上弦梁和斜杆的不均匀热胀冷缩发生适应性转动或者倾斜，加固上梁结构的同时避免了立柱由于应力集中而损坏。
