Peripheral support large-span space steel truss mounting structure and mounting method thereof
The invention provides a peripheral support large-span space steel truss mounting structure and a mounting method thereof. The peripheral support large-span space steel truss mounting structure comprises a peripheral support, an internal steel truss and a pre-stretching structure, the pre-stretching structure comprises fastening I-shaped steel, a fastening suspension part and a first steel strand, the internal steel truss comprises a plurality of I-shaped steel beams, two pieces of fastening I-shaped steel are fixedly installed at the bottom of a lower flange of each I-shaped steel beam through fixing bolts, the fastening suspension part is cylindrical, a through first long-strip-shaped groove is formed in the side wall of the fastening suspension part in the axial direction, and the first long-strip-shaped groove is communicated with the first long-strip-shaped groove. The fastening hanging piece is fixedly installed at one end of one fastening I-shaped steel beam, the anchoring plate is fixedly installed at the end of the other fastening I-shaped steel beam, the end of the first steel strand is fixedly installed on the anchoring plate through the fastening piece, and the first steel strand is wound on the two fastening I-shaped steel beams at the bottom end of each I-shaped steel beam. The internal steel truss is reinforced by adopting a prestress reinforcing method, so that the structural deformation is reduced.
本发明提供周边支承大跨度空间钢桁架安装结构及其安装方法，周边支承大跨度空间钢桁架安装结构包括周边支承、内部钢桁架、预拉伸结构；预拉伸结构包括：紧固工字钢、紧固悬挂件、第一钢绞线，内部钢桁架包括若干工字钢梁，每个工字钢梁的下翼缘底部通过固定螺栓固定安装2个紧固工字钢，紧固悬挂件呈圆柱筒形，在紧固悬挂件的侧壁上沿轴向开设有贯通的第一长条槽，紧固悬挂件固定安装在在其中一个紧固工字钢的一端，在另一个紧固工字钢的端部固定安装有锚定板，第一钢绞线的端部通过紧固件固定安装在锚定板上，第一钢绞线缠绕在每个工字钢梁的底端的两个紧固工字钢上。本发明采用预应力加固法对内部钢桁架进行加固，以减小结构变形。
