Anchoring device for bridge support heightening
The invention relates to the technical field of bridge support heightening, and discloses an anchoring device for bridge support heightening, which comprises an anchor rod, an outer sleeve, an anchoring bolt, a heightening sleeve, a limiting structure, a bridge bottom plate and a support top plate, the anchor rod is in threaded connection with the top end of the outer sleeve, and the heightening sleeve is sleeved in the outer sleeve; the height adjusting sleeve and the outer sleeve can move in the relative axial direction. The limiting structure is used for limiting the circumferential rotation of the height adjusting sleeve; the end of the outer sleeve is fixed to a bridge bottom plate, the anchor bolts sequentially penetrate through the support top plate and the bridge bottom plate to be in threaded connection with the heightening sleeve, and after the bridge support is heightened, the space between the bridge bottom plate and the support top plate is filled with a heightening base plate. According to the anchoring device for bridge support heightening, bridge support heightening can be achieved under the condition that the bolts are not dismounted, meanwhile, the bolting length of the anchoring bolts is not reduced, and the anchoring performance is not affected.
本发明涉及桥梁支座调高技术领域，公开了一种用于桥梁支座调高的锚固装置，包括：锚杆、外套筒、锚固螺栓、调高套筒、限位结构、桥梁底板和支座顶板，所述锚杆与外套筒顶端通过螺纹连接，所述调高套筒套在外套筒内，调高套筒和外套筒两者之间可以在相对轴向进行移动；所述限位结构用于限制所述调高套筒进行周向转动；所述外套筒端部与桥梁底板固定，所述锚固螺栓依次穿过所述支座顶板和桥梁底板与所述调高套筒螺纹连接，当桥梁支座调高后，桥梁底板和支座顶板中间填充有调高垫板。本发明提供的一种用于桥梁支座调高的锚固装置可在不拆除螺栓的情况下实现桥梁支座调高，同时锚固螺栓的栓接长度未减小，不影响锚固性能。
