Primary and secondary beam cross lap connecting structure and connecting method thereof
The invention discloses a primary and secondary beam cross lap connecting structure and a connecting method thereof. The connecting structure comprises a prefabricated main beam and a prefabricated secondary beam which are formed by pouring concrete, and is characterized in that a notch is formed in the prefabricated main beam; the prefabricated secondary beam comprises a first prefabricated secondary beam and a second prefabricated secondary beam which are connected through a plurality of reinforcing steel bars; the reinforcing steel bars on the lower layer of the prefabricated secondary beamare supported at the bottom of the notch; and a concrete pouring cavity is defined by the first prefabricated secondary beam, the second prefabricated secondary beam and the notch. According to the primary and secondary beam cross lap connecting structure and the connecting method thereof, by processing joints at the lap joints of the main beam and the secondary beam, the problems of blockage andthe like during sleeve installation are avoided, the structural safety is improved, and the assembly difficulty is reduced. Furthermore, the connecting method reduces the lap joint of prefabricated secondary beam steel bars, reduces consumption of the steel bars, and conforms to the concept of sustainable development. Meanwhile, the mode that main reinforcements of the main beams are not disconnected, and all reinforcements of the secondary beams are not disconnected is adopted, so that the connecting strength of the prefabricated secondary beams is improved, and the overall structural safetyis greatly guaranteed.
本发明公开了一种主次梁十字搭接连接结构及其连接方法，连接结构包括采用混凝土浇筑成型的预制主梁和预制次梁，其特征在于，预制主梁上设置有缺口，预制次梁包括通过多根钢筋连接的第一预制次梁和第二预制次梁，预制次梁下层的钢筋支撑在缺口的底部，第一预制次梁、第二预制次梁和缺口围设成一混凝土浇筑腔。本发明通过对主次梁搭接处节点处理，避免安装套筒时产生的堵塞等问题，提高结构安全性，降低装配难度。进一步的，该连接方式减少了预制次梁钢筋搭接，降低了钢筋消耗，符合可持续发展理念。同时，采用的是主梁主筋不断开，次梁所有钢筋均不断开的方式，提升了预制次梁的连接强度，整体的结构安全得到更大的保障。
