Anchorage device for tensioning arch bridge sling
The invention relates to the technical field of arch bridge sling tensioning anchorage devices, in particular to an anchorage device for arch bridge sling tensioning, which comprises a first tensioning groove, a first anti-skid groove, a clamping piece, a stranded wire hole, a second anti-skid groove and a tensioning reinforcing piece, the bulletproof fixing device has the beneficial effects that a limiting block is jacked by a jacking spring to enter a limiting groove to limit a fixing rod, an anti-disengaging rod prevents the limiting block from disengaging from the jacking groove, and after the bulletproof fixing rod enters a bulletproof outer plate and a bulletproof inner plate, the bulletproof limiting block is pressed into the bulletproof limiting groove through an inclined face formed in the bulletproof limiting block, so that the bulletproof fixing rod enters the lower end of the bulletproof limiting block; the bulletproof limiting spring abuts against the bulletproof limiting block to limit the bulletproof fixing rod, the clamping pieces are prevented from rebounding, the two sets of clamping pieces are spliced, the two sets of third tensioning grooves are matched with the third tensioning blocks, the tensioning blocks are matched with the second tensioning grooves, and therefore friction between the clamping pieces and the steel strand is enhanced, the steel strand is effectively prevented from loosening, and tensioning of the sling is guaranteed.
本发明涉及拱桥吊索张拉锚具技术领域，具体为一种用于拱桥吊索张拉的锚具，所述用于拱桥吊索张拉的锚具包括：第一张拉槽、第一防滑槽、夹片、绞线孔、第二防滑槽及张拉加强件；有益效果为：通过顶持弹簧顶持限位块进入限位槽内部对固定杆限位，防脱杆防止限位块脱离顶持槽，防弹固定杆进入防弹外板与防弹内板内部后，通过防弹限位块开设的斜面将防弹限位块压入防弹限位槽内部，从而进入防弹限位块下端，使得防弹限位弹簧顶持防弹限位块对防弹固定杆限位，防止夹片回弹，两组夹片拼接，则两组第三张拉槽与第三张拉块配合，且张拉块与第二张拉槽配合，从而加强夹片与钢绞线的摩擦，有效防止钢绞线松动，从而保证了吊索的张拉。
