Large-span special-shaped steel-concrete column and construction method thereof
The invention provides a large-span special-shaped steel-concrete column. The large-span special-shaped steel-concrete column comprises a concrete base buried underground; the lower part of the Y-shaped steel column is vertically mounted on the concrete base, and the upper part of the Y-shaped steel column is provided with an outer side column and an inner side column which are oppositely diverged; the concrete anchoring foundation is poured on the upper portion of the concrete base, and the lower portion of the Y-shaped steel column is embedded in the concrete anchoring foundation; the concrete supporting column is poured on the upper portion of the concrete anchoring foundation, and the inner side column is embedded in the concrete supporting column. The method has the beneficial effects that the inner side column of the Y-shaped steel column and the concrete anchoring foundation are integrally stressed, so that the overturning moment of the roof truss can be resisted, and the stability and the safety during installation of the roof truss are ensured; jig frame measures are avoided, the thickness of the base is reduced, the pouring workload is reduced, and the construction efficiency is improved; concrete is poured into the Y-shaped steel column so as to guarantee the upper eccentric load requirement, reduce the anchoring depth needed by foundation eccentric stress and reduce the foundation thickness.
本发明提供一种大跨度异形钢混柱，包括：埋设于地下的混凝土基座；Y形钢柱，其下部竖直安装于所述混凝土基座上、上部设有相对岔开的外侧柱和内侧柱；浇筑于所述混凝土基座上部的混凝土锚固基础，所述Y形钢柱下部埋设于所述混凝土锚固基础内；以及浇筑于所述混凝土锚固基础上部的混凝土支柱，所述内侧柱埋设于所述混凝土支柱内。本发明的有益效果：Y形钢柱的内侧柱与混凝土锚固基础整体受力，可以抵抗屋面桁架的倾覆力矩，保证屋面桁架安装时的稳定及安全性；避免使用胎架措施，减低基座厚度，降低浇筑工作量，提高施工效率；Y形钢柱的内部浇筑混凝土，以保证上部偏心荷载要求，减少基础偏心受力所需锚固深度，降低基础厚度。
