异形三角锥网架是一种用于中、大跨度建筑的屋面结构.该网架由上弦杆、下弦杆、腹杆及球节点组成.上弦杆件网格图由正三角形及少量的直角三角形组成.下弦杆件网格图由正三角形及少量的非正三角形组成.弦杆与腹杆组成的三角锥大部分为正三角锥,少量为非正三角锥.该网架应用于矩形、不等边八边形及其派生出来的其他复杂的建筑平面.该网架具有空间刚度好、受力条件好、节省钢材、造型美观及便于整体吊装等优点.
Profiled triangular cone grid is a kind of roof structure for medium and large span buildings. The grid consists of top chord, bottom chord, web strut and ball joint. The grid of top chord is made up of a right triangle and a small number of right triangles. Composition. The lower chord mesh is composed of a regular triangle and a small number of non-standard triangles. The triangular cone formed by chords and webs is mostly a positive triangle cone, and a small amount is a non-positive triangular pyramid. The grid is applied to a rectangle, not Equilateral octagon and other complex architectural planes derived from it. The grid has the advantages of good space rigidity, good stress conditions, saving steel, attractive appearance, and easy overall lifting.
