Abstract
An inclined pulled rope connector relates to tool technology field for architecture pre-stress construction, which comprises a connection barrel and a connection rod which passes through one end of the connection barrel. A bearing is provided between the connection barrel and the connection rod. Compared to prior art, the utility model can eliminate torsion stress during traction of towing cable or inclined pulling rope, thus achieves purpose of safely drawing.
Description
Technical field
The utility model relates to building pre-stress construction technical field of tools, the connector that especially a kind of suspension cable installation that is used for cable stayed bridge is used.
Background technology
Existing stayed-cable bridge is when installing its suspension cable, for the suspension cable anchor head is installed on the bridge tower, usually draw with the jack tension drag cable, in the traction stretching process, jack acts on the anchor head of suspension cable successively by the connecting rod of drag cable, connector.It has connecting cylinder the existing connector that is used for the stretch-draw suspension cable, and connecting rod passes with connecting cylinder from connecting cylinder one end fixedlys connected, and connecting cylinder is connected with drag cable, and suspension cable connects jack again, and drag cable and suspension cable are relatively-stationary.Because there is torsional stress in suspension cable after making, and drag cable is turned round system, also there is torsional stress during tension, so when traction stretch-draw suspension cable, suspension cable can produce twisting resistance, because jack is to fixedly connected with suspension cable, the twisting resistance of suspension cable can cause drag cable to reverse, when serious even can twist off drag cable, cause accident.The way of reversing internal force when overcoming suspension cable traction stretch-draw at present is that the drag cable symmetry arrangement with left and right rotation direction allows it offset torsional stress voluntarily, this way is not fundamentally eliminated torsional stress, and just allow the drag cable of symmetry arrangement of left and right rotation direction be subjected to opposite torsion mutually, when torsion is excessive, drag cable also has the precedent that twists off, and has potential safety hazard.
Summary of the invention
The utility model provides a kind of suspension cable connector, and it solved produces the problem of torsional stress when being drag cable or suspension cable traction stretch-draw.
To achieve these goals, the technical scheme that the utility model adopted is: it includes connecting cylinder and from the connecting rod that this connecting cylinder one end passes, between described connecting cylinder and described connecting rod bearing is housed.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
Between connecting cylinder and connecting rod, bearing is housed, because the turnability of bearing, connecting rod and connecting cylinder can relatively rotate, the two is connected with suspension cable anchor head, drag cable respectively, drag cable is connected with jack again, make between suspension cable, drag cable and the jack three to become rotating connection, make the three not be subjected to the torsional stress effect fully, improved safety of construction greatly by fixedly connected.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Instantiation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Among the embodiment as shown in Figure 1, it includes the utility model connecting cylinder 3 and from the connecting rod 2 that this connecting cylinder one end passes, between connecting cylinder 3 and connecting rod 2 bearing 4 is housed, and this bearing is a taper roll bearing, and bearing 4 is contained on the shaft shoulder of connecting rod 2.When connector is subjected to huge axial tension, because the effect of bearing 4, connecting cylinder 3 and connecting rod 2 can rotate, connecting rod 2 and suspension cable anchor head 1 are by being threaded, connecting cylinder 3 its other ends are provided with anchor slab 8, and wedge shape intermediate plate 7 is housed on this anchor slab, and wedge shape intermediate plate 7 is used for clamping an end of drag cable, drag cable is steel strand 5 herein, and steel strand 5 other ends are clamped by the wedge shape intermediate plate on the jack 69.When steel strand 5 are strained by jack 6, when suspension cable or steel strand 5 twist, suspension cable anchor head 1 is owing to be connected with connecting rod 2, connecting rod 2 will drive bearing 4 rotations, and connecting cylinder 3 is motionless, and the steel strand 5 that are connected with connecting cylinder 3, jack 6 all are not subjected to the torsional stress effect like this, has just eliminated the torsional stress of suspension cable or steel strand 5, reach safe traction, the purpose of safe stretch-draw.
