Expansion joint force transfer structure for continuous reinforced concrete pavement and construction method
The invention discloses a continuous reinforced concrete pavement expansion joint force transfer structure and a construction method. The force transmission structure is installed at the expansion joint after binding of a steel bar frame of a concrete slab is completed, an end formwork is erected and before concrete pouring, the force transmission structure comprises a force transmission rod and an expansion joint plate fixed to the middle of the force transmission rod, the expansion joint plate is arranged in the expansion joint, and the expansion joint plate is connected with the expansion joint. Through holes are correspondingly formed in the portions, on the two sides of the expansion joint, of the first end formwork and the second end formwork, the two ends of the dowel bar penetrate through the first end formwork and the second end formwork respectively to stretch into the first concrete reinforcement frame and the second concrete reinforcement frame on the two sides of the expansion joint, and a buffer sleeve is arranged at one end of the dowel bar. And the buffer sleeve and the buffer mechanism are respectively connected with the concrete reinforcement frame on the corresponding side. In the construction process, fixation is stable, deformation and displacement of the dowel bar can be avoided, after the dowel bar is installed, the dowel bar can automatically contract along with expansion of concrete in the concrete expansion process, and the force transmission effect is improved.
本发明公开了一种连续配筋混凝土路面胀缝传力结构及施工方法。所述传力结构在混凝土板的钢筋框架绑扎完成、且端头模板架设后，混凝土浇筑前安装在胀缝处，所述传力结构包括传力杆和固定在传力杆中部的胀缝板，所述胀缝板置于胀缝内，在胀缝两侧的第一端头模板和第二端头模板上对应开设有穿孔，所述传力杆的两端分别穿过第一端头模板和第二端头模板伸入胀缝两侧的第一混凝土钢筋框架和第二混凝土钢筋框架，所述传力杆一端设有缓冲套筒，所述缓冲套筒和缓冲机构分别与对应侧的混凝土钢筋框架连接。本发明在施工过程中固定稳定，可以避免传力杆变形、移位，且传力杆安装好之后在混凝土膨胀过程中，能够随着混凝土的膨胀自收缩，提高传力效果。
