Hanging basket rear anchoring auxiliary device for cantilever beam pouring, setting method and application
The invention provides a hanging basket rear anchoring auxiliary device for cantilever beam pouring. The device comprises an anchor rod, a jack, an anchor box and a connecting sleeve, the anchor box is welded to the end of a hanging basket rear anchor beam, through holes are formed in the upper surface and the lower surface of the anchor box, the jack is arranged in the anchor box, the anchor rod penetrates through the anchor box and the jack, the lower end is connected with a bridge deck concrete pre-embedded deformed steel bar through the connecting sleeve, and the upper end is fixed on the jack; a base plate is arranged on the upper portion of the jack, a through hole corresponding to the anchor box is formed in the base plate, the connecting sleeve is arranged on the base plate, and the anchor rod is fixed to the jack through the base plate and the connecting sleeve. A hanging basket and a beam body are integrally pressed down and integrally anchored when being fixed and released, so that the risk of breakage caused by concentrated stress of anchoring finish rolling reinforcing steel bars during single anchoring is avoided, and the construction safety is ensured. The manufacturing cost is low, the operation is easy, the construction period is shortened, and potential safety hazards are reduced.
本发明公开了一种悬臂梁浇筑用的挂篮后锚固辅助装置，包括锚杆、千斤顶、锚盒、连接套筒，其中，锚盒焊接于挂篮后锚梁端部，锚盒的上下表面开设通孔，锚盒内设置千斤顶，锚杆穿过锚盒、千斤顶，下端通过连接套筒与桥面混凝土预埋螺纹钢连接，上端固定在千斤顶上；千斤顶上部设置垫板，垫板上开设与锚盒相应的通孔，垫板上设置连接套筒，通过垫板与连接套筒将锚杆固定在千斤顶上。挂篮与梁体间的固定和解除施工时采用整体下压，整体锚固，避免了单根锚固时锚固精轧钢筋集中受力产生断裂的危险，保证施工安全。制造成本低，操作简单，缩短工期，降低了安全隐患。
