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.
Description
technical field [0001] The invention relates to the technical field of construction of non-standard inclined large-span steel-concrete structures for venues, in particular to a large-span special-shaped steel-concrete column and a construction method thereof. Background technique [0002] For gymnasiums and other large-space venue buildings, the area is irregular in shape, such as fan-shaped. The roof is used as a planted roof, or is designed with photovoltaic panels, so it is necessary to construct inclined roof panels (trusses). like figure 1 As shown, this type of building only relies on the columns at both ends to bear the long-span roof load. If the columns and the roof adopt an all-steel structure, the all-steel columns support 1a the inclined roof 2a, and the height of one end is higher and the height of the other end is lower. If the drop is large, the steel column on the lower side will be subjected to a larger overturning moment, and the risk of installation will...
