Prefabricated box culvert steel bar self-positioning device and mounting method thereof
The invention discloses a prefabricated box culvert reinforcing steel bar self-positioning device and an installation method thereof, and belongs to the technical field of prefabricated box culverts.The prefabricated box culvert reinforcing steel bar self-positioning device comprises a prefabricated concrete box body and longitudinal bars pre-buried in the prefabricated concrete box body, one ends of the longitudinal bars are pre-buried in the prefabricated concrete box body, and the other ends of the longitudinal bars are pre-buried in the prefabricated concrete box body; the other end of the longitudinal bar extends out of one end face of the prefabricated concrete box body in the longitudinal direction, and a steel bar self-positioning assembly is arranged at the other end, corresponding to the longitudinal bar, of the prefabricated concrete box body; the reinforcing steel bar self-positioning assembly comprises an axial abutting device, an outer cylinder sleeve and an inner inserting rod, an inserting hole is formed in the end face of the prefabricated concrete box body, the axial abutting device is arranged in the inserting hole, and the inner end of the inner inserting rod is matched with the axial abutting device. According to the device, the prefabricated box culvert reinforcing steel bars can be conveniently positioned, and the assembling efficiency of the prefabricated box culvert can be greatly improved through the self-positioning effect.
本发明公开了一种预制箱涵钢筋自定位装置及其安装方法，属于预制箱涵技术领域，包括预制混凝土箱体以及预埋在所述预制混凝土箱体内的纵筋，所述纵筋的一端预埋在所述预制混凝土箱体内，另一端沿纵向从预制混凝土箱体的一端面伸出，与所述纵筋对应在预制混凝土箱体的另一端设置有钢筋自定位组件；所述钢筋自定位组件包括轴向抵紧装置、外缸套和内插杆，所述预制混凝土箱体的端面上形成有插孔，所述轴向抵紧装置设置在所述插孔内，所述内插杆的内端与所述轴向抵紧装置配合。本发明装置可以便于预制箱涵钢筋的定位，通过自定位的效果，可以极大提高预制箱涵的拼装效率。
