Superimposed beam and construction method thereof
The embodiment of the invention discloses a superposed beam and a construction method thereof. According to one specific implementation mode of the superposed beam, two precast beams with the L-shaped or inverted-T-shaped cross sections and a post-cast superposed layer are spliced into the whole superposed beam, precast beam stirrups extend out of a precast beam rectangular body and the top faces of lifting lugs, and the precast beams and post-cast concrete work together through cooperation of the stirrups and key grooves; and a space without transverse barrier up and down is formed between the vertical side surface of the rectangular main body of the precast beam and the stirrups extending out of the top surfaces of the lifting lugs, and precast beam processing is realized through secondary concrete pouring. Through optimization of the cross section of the precast beam, the stirrup form and the machining process, on the basis that the self weight of the precast beam can be reduced by 80%, the range of the post-cast laminated layer is expanded, connection of the two precast beams is enhanced, the torsion resistance of the assembled laminated beam is improved, meanwhile, efficient machining of the precast beam with the exposed ribs and universality of molds are achieved through the split side molds, and the production cost is reduced. And the labor cost of precast beam processing and the mold spreading cost are reduced.
本公开的实施例公开了叠合梁及其建造方法。该叠合梁的一具体实施方式包括：采用两根横截面为L形或倒T形的预制梁与后浇叠合层拼装为整体叠合梁，预制梁箍筋从预制梁矩形主体、挑耳顶面伸出，依靠箍筋、键槽协同预制梁与后浇混凝土的共同工作，在预制梁矩形主体竖向侧面与挑耳顶面伸出的箍筋之间形成上下无横向阻隔的空间，通过混凝土二次浇筑实现预制梁加工。本公开通过预制梁横截面、箍筋形式和加工工艺优化，在可将预制梁自重降低80％的基础上，扩大后浇叠合层范围增强了两根预制梁的连接，改善了组装叠合梁的抗扭性能，同时采用分体侧模实现了带出筋预制梁的高效加工和模具通用，降低了预制梁加工的人工成本和模具摊销成本。
