Embedded steel truss and reinforced concrete combined cast-in-place beam structure and construction method
The invention discloses an embedded steel truss and reinforced concrete combined cast-in-place beam structure and a construction method. The combined cast-in-place beam structure comprises a steel truss and a steel reinforcement framework. At least two steel trusses are arranged, and the steel trusses are connected into a truss frame through truss connecting pieces; the steel bar framework comprises a plurality of stirrup rings arranged outside the steel truss in a sleeving mode and connecting steel bars connected with the stirrup rings, latticed tie bars are arranged in the stirrup rings, the plane where the stirrup rings are located is perpendicular to the length direction of the steel truss, and the latticed tie bars are fixed to the truss frame. The steel reinforcement framework is filled with concrete, and the steel truss and the steel reinforcement framework are wrapped by the concrete. The combined cast-in-place beam structure is reasonable in structural design, the embedded steel truss serves as a structural main supporting piece, the steel reinforcement framework is matched to provide support for concrete of the beam, the characteristic that a reinforced concrete structure and the steel truss structure are large in bearing capacity can be jointly exerted, and the combined cast-in-place beam structure is suitable for large-span engineering and has the fireproof performance of a concrete beam; the application prospect is good.
本发明公开了一种内嵌钢桁架与钢筋混凝土组合现浇梁结构及施工方法，组合现浇梁结构包括钢桁架和钢筋骨架；钢桁架至少有两片且钢桁架之间通过桁架连接件连成桁架框；钢筋骨架包括套设在钢桁架外的多个箍筋环和连接多个箍筋环的连接钢筋，箍筋环内设有网格状拉结筋，箍筋环所在平面与钢桁架的长度方向垂直，网格状拉结筋与桁架框固定，钢筋骨架内填充有混凝土且钢桁架及钢筋骨架被混凝土包裹在内。本发明的组合现浇梁结构，结构设计合理，以内嵌钢桁架作为结构主支撑件，配合有钢筋骨架为梁的混凝土提供支撑，能够共同发挥钢筋混凝土结构与钢桁架结构承载力大的特点，适用于大跨度工程，同时兼具混凝土梁的防火性能，应用前景好。
