Double-prestressed-pipe truss structure with Y-shaped middle column for super-large span
The invention discloses a double-prestressed-pipe truss structure with a Y-shaped middle column for a super-large span, and relates to the technical field of large-span space structures. The double-prestressed-pipe truss structure with the Y-shaped middle column for the super-large span comprises the middle column, a main truss, an inhaul cable, a support rod and a support seat, wherein the middlecolumn is in a Y shape, and the main truss is connected to the top end of the middle column. According to the double-prestressed-pipe truss structure with the Y-shaped middle column for the super-large span, a prestressed truss can adapt to a large span, the stress is reasonable, and the effect of economy is achieved; the support reaction is effectively reduced by the pre-tension inhaul cable; compared with an m-shaped section, snow accumulation in the middle can be effectively avoided; the occupation of a construction site is reduced, and the influence on on-site production and operation during the construction period is reduced; and the sections of the truss and the middle column adopt a quadrilateral and inverted triangular transition form according to the section bending moment, so that the pipe diameter can be effectively reduced, and the effects of economy and reasonability are achieved.
本发明公开了一种带Y形中柱适用于超大跨度的双预应力管桁架结构,涉及大跨度的空间结构技术领域。该带Y形中柱适用于超大跨度的双预应力管桁架结构,包括中柱、主桁架、拉索、撑杆和支座,所述中柱为Y型,所述中柱的顶端连接主桁架。该带Y形中柱适用于超大跨度的双预应力管桁架结构的预应力桁架能适应大跨度,受力合理,经济节约;预拉力拉索有效降低了支座反力;相比m形剖面,本专利能有效避免在中部的积雪;减少施工场地的占用,降低施工期间对现场生产运营的影响;桁架和中柱的剖面根据截面弯矩的大小采用四边形、倒三角形过度的形式,能有效降低管径,经济合理。
