End bracing column of power transformation framework and multi-span connecting framework
The invention discloses an end bracing column of a power transformation framework and a multi-span connecting framework. The end bracing column of the power transformation framework comprises an end bracing herringbone column, a diagonal bracing and diagonal web members, wherein the top end of the end bracing herringbone column is connected with the top end of the diagonal bracing to form a quadrihedron structure with an isosceles triangle section, the diagonal web members are arranged between the end bracing herringbone column and the diagonal bracing and arranged in a zigzag shape from bottom to top, a plane truss consisting of column limbs of the end bracing herringbone column, the diagonal bracing and the diagonal web members is formed in a diagonal plane where the two column limbs ofthe end bracing herringbone column and the diagonal bracing are located, and the plane truss and the end bracing herringbone column form a quadrihedron space lattice type end bracing column. Accordingto the arrangement mode, the statically indeterminate times of the structure are increased, the overall and local bending rigidity, the torsional rigidity and the upright post stability of the end bracing can be remarkably enhanced, the local horizontal action from the middle of a column body of the framework is effectively resisted, the stress states of the end bracing herringbone column, the end bracing column and the whole framework are improved, and the aims of optimizing the section sizes of the end bracing column and the end bracing herringbone column and improving the safety of the structure are achieved.
本发明公开的一种变电构架的端撑柱及多连跨构架，包括端撑人字柱、斜撑和斜腹杆；所述端撑人字柱的顶端与斜撑的顶端连接，形成断面为等腰三角形的三角锥结构，斜腹杆设置在端撑人字柱和斜撑之间，自下而上呈之字状布置，在端撑人字柱两个柱肢与斜撑所在的斜平面内，形成由端撑人字柱的柱肢和斜撑以及斜腹杆构成的平面桁架，再与端撑人字柱共同构成三角锥空间格构式端撑柱。该布置形式提高了结构的超静定次数，能显著增强端撑的整体和局部抗弯刚度、抗扭刚度以及立柱的稳定性，有效抵抗来自于构架柱身中部的局部水平作用，改善端撑人字柱、端撑柱及整个构架受力状态，进而做到优化端撑柱及端撑人字柱截面尺寸，提高结构的安全度的目的。
