Variable-stiffness steel box concrete composite beam, structure and construction method
The invention discloses a variable-stiffness steel box concrete composite beam, a structure and a construction method. Openings are formed in upper flange plates of the composite beam in the length direction of the beam, the ends of upper flanges are connected into a whole, or openings in the ends are smaller than openings in the middles, or the thickness of the ends of the upper flanges is larger than that of the middles; and the composite beam structure and a column body or a shear wall form a connecting system and are correspondingly connected. Through the variable-opening design of the composite beam, the requirements of different rigidities can be met; studs and shear-resistant pieces are arranged in the composite beam, so that the work together with concrete can be improved; through combined arrangement of in-beam concrete, in-beam stirrups, in-beam longitudinal bars and in-beam connecting ribs, the overall strength of the composite beam can be enhanced, and the connection with other structures is facilitated; through the T-shaped arrangement of the composite beam, the connection with an upper floor slab is facilitated, and the stress of a transverse part and the integrity of connection of an upper structure and a lower structure are guaranteed; through the arrangement that the composite beam is connected with the column body and the shear wall, convenient and fast construction of a fabricated building is facilitated; and the overall rigidity and the anti-seismic property are effectively improved.
本发明公开了一种变刚度钢箱混凝土组合梁、结构及施工方法，其中组合梁上翼缘板沿着梁长度方向开口，上翼缘端部连为一体或端部开口小于中部开口，或上翼缘端部厚度大于中部厚度；组合梁结构分别与柱体或剪力墙形成连接体系并对应连接。本发明通过组合梁的变开口设计，利于适应不同刚度的需求；组合梁内部设置有栓钉和抗剪件，可提升与混凝土的共同工作；通过梁内混凝土、梁内箍筋、梁内纵筋和梁内连骨的联合设置，可加强组合梁整体强度，便于与其他结构的连接；通过组合梁T形设置，利于与上部楼板连接且保证横部的受力和上下结构连接的一体性；通过组合梁与柱体和剪力墙连接的设置，利于装配式建筑的便捷施工；有效提升整体刚度和抗震性能。
