Description
Technical field
The utility model relates to a kind of bridge cable, relates in particular to a kind of bridge steel plate twisted wire drag-line.Belong to the road and bridge technical field.
Background technology
In heavy construction structure, steel work cable stayed bridge and arch bridge, because structure is limit, require to adopt the cable spiral of less internal diameter.Traditional chill casting anchor wire digging line, hot casting anchor wire digging line and steel strand group anchor inhaul cable because the anchor head size is large, are difficult to realize this requirement.
By the extended steel strand integral bundle extruding anchor of external SEEE engineering method drag-line, because the anchor head size is little, in above-mentioned building structure and bridge engineering, be applied at present.The patent No. is that 200720083125.0(sees Fig. 1) utility model patent a kind of steel strand integral bundle extrusion anchor cable guy cable is disclosed, solved the large problem of anchor head size, but had the high weak point of cost of manufacture:
1, the anchorage cover is long, and its domestic demand is offered the slotted hole identical with the steel strand radical;
2, the anchorage cover needs to adopt special-purpose large-tonnage extrusion equipment and dedicated extruded mould to carry out whole bundle extruding; The drag-line of every kind of specification needs to be equipped with the extrusion die corresponding with this specification, and needs by verifying squeezing effect; During extruding, the suffered extruding anchored force of each layer steel strand in the anchorage cover does not wait.
3, be squeezed into the anchorage cover of one with the drag-line cable body, need threading on special purpose machine tool, for the drag-line of length greater than 20m, processing difficulties.
Exceed common chill casting anchor wire digging line, hot casting anchor wire digging line and steel strand group anchor inhaul cable 5 ~ 8 times because above-mentioned reason causes this kind drag-line price, increased the bridge construction cost.
Summary of the invention
The purpose of this utility model is above-mentioned deficiency, and little, easy to make, the lower-cost steel strand extruding anchor of a kind of anchor head size drag-line is provided.
The purpose of this utility model is achieved in that a kind of steel strand extruding anchor drag-line, drag-line cable body in the middle of comprising and the anchoring piece at two ends, described drag-line cable body is comprised of many steel strand, described anchoring piece is divided into anchoring unit and sealing unit, described anchoring unit comprises: seal closure, pressing plate, extruded sleeve, anchor cup and nut, interior loaded plate is set in the anchor cup, offer the steel strand identical with drag-line cable body radical on the interior loaded plate and pass through the hole, steel strand independently pass this hole separately, extruded sleeve is installed in the steel strand end and is made it and steel strand are squeezed into one, pressing plate is connected by bolt described extruded sleeve with the anchor cup, seal closure is with pressing plate, extruded sleeve covers and is threaded with the anchor cup, be conical cavity behind the loaded plate, described anchor cup peripheral hardware screw thread screws with nut; Described sealing unit comprises: sealing drum, constrainer, sealing ring and inserts, and the sealing drum front end is established screw thread, is connected with the threaded engagement of anchor cup rear end; Constrainer is positioned at sealing drum, and inserts is filled in seal closure, anchor cup and the sealing drum, and sealing ring is positioned at the sealing drum rear end.
The beneficial effects of the utility model are:
Because adopt said structure, the hole identical with the steel strand radical of offering in the anchor cup is more shallow, processing cost is low; Anchor cup external screw thread is processed before extruding, avoids the difficulty of the monolithic extruded rear threading of anchor cup; At every steel strand extruded sleeve is installed, is pushed anchoring with the small-sized extrusion equipment of same specification, the monolithic extruded required equipment of guy anchor cup and the extrusion die that reduce different size drop into.Therefore the steel strand extruding anchor drag-line of the utility model can greatly reduce manufacturing cost under the prerequisite of guaranteed performance.
