Abstract
A low tower stayed-cable bridge cable saddle with anti-skid anchor includes a cable saddle and two anti-skid anchors. The utility model is characterized in that: A stayed-cable gets across the cable saddle and be locked firmly by the two anti-skid anchors which are arranged at the two sides of the cable saddle. The cable saddle is composed of a cable saddle outer tube (6) and a cable saddle inner tube (7); the anti-skid anchor is composed of an anti-skid anchor tube (2), a gland (4), a base plate (5) and epoxy mortar (3) which is filled in the anti-skid anchor tube (2); an anti-skid cable clip (9) is arranged in the anti-skid anchor tube (2); the anti-skid cable clip (9), which is connected firmly with a seal plate (4)by means of an anti-skid cable clip clamping device, is clipped on the stayed-cable (1) and be locked tightly by means of a locking bolt (10); the anti-skid cable clip clamping device is a bolt (81) or a locknut (82). The utility model can enlarge the interface of the epoxy mortar and a strand so as to make the anchor-hold to be more reliable; moreover, enough anti-skid force can be obtained but the size of the inner tube is comparatively small under the same conditions.
Description
Technical field
The utility model relates to a kind of cable-stayed bridge cable cable saddle, particularly with the cable saddle of anti-skidding ground tackle.
Background technology
The low-pylon cable-stayed bridge drag-line adopts cable saddle support on the tower in the market, because reasons in structure unavoidably brings tower both sides drag-line to be subjected to force unbalance in building and operating, therefore the drag-line to the cable saddle section will limit, and promptly anti-skid anchor must be arranged.At present, low-pylon cable-stayed bridge adopts the perfusion epoxy mortar to bond in the tower both sides to the drag-line outlet section both at home and abroad, as shown in Figure 5: the low-pylon cable-stayed bridge cable saddle of existing band anti-skid anchor is made up of drag-line (20), anti-skid anchor tube (21), epoxy mortar (22), sealing mat (23), backing plate (24), cable saddle outer tube (25), the interior pipe of cable saddle (26) etc., from implementation result is can satisfy the antiskid requirement substantially, and feasible process.But also have following weak point: 1, in the interior pipe of cable saddle, the contact surface of steel strand and epoxy mortar is less, and for the contact surface that guarantees that it is enough, size of pipe will be done greatlyyer in it; 2, in the interior pipe of cable saddle, the contact surface of steel strand and epoxy mortar has only upper surface, and bottom steel strand and epoxy mortar fully do not bond, the skid resistance skewness of formation.
Technology contents
The technical problems to be solved in the utility model is: the existing steel strand of low-pylon cable-stayed bridge cable saddle of existing this band anti-skid anchor and the contact surface of epoxy mortar have only the contact surface of upper surface, steel strand and epoxy mortar less, steel strand and epoxy mortar fully do not bond, the skid resistance skewness that forms with and the size of interior pipe to do greatlyyer problem, a kind of contact surface that increases steel strand and epoxy mortar is provided, makes steel strand and epoxy mortar is more abundant bonds, safe and reliable, skid resistance is enough big and the cable saddle of the band friction skidding device that interior pipe size is less.
The technical scheme that solves its above-mentioned technical problem is: a kind of low-pylon cable-stayed bridge cable saddle with anti-skid anchor, comprise cable saddle and be positioned at the anti-skidding anchor head at two ends, drag-line passes the anti-skidding anchor head anchoring that cable saddle is positioned at the cable saddle two ends, described cable saddle is by the cable saddle outer tube, pipe constitutes in the cable saddle, described anti-skidding anchor head is by the anti-skid anchor tube, sealing mat, backing plate and the can epoxy mortar in the anti-skid anchor tube constitutes, it is characterized in that: the antiskid cord clip is arranged in the anti-skid anchor tube, this antiskid cord clip is stuck on the drag-line, tighten with lock bolt, and connect with sealing plate is fastening by cord clip antiskid top-fastener.
Described cord clip antiskid top-fastener can be a bolt, also can be locking nut.
Owing to adopt said structure, the low-pylon cable-stayed bridge cable saddle of the band anti-skid anchor of the utility model is compared with the low-pylon cable-stayed bridge cable saddle of existing band anti-skid anchor has following good effect:
1, owing to be provided with the antiskid cord clip in the cable saddle, the antiskid cord clip can provide a part of skid resistance, makes that the antiskid of cable saddle is more reliable;
2, owing to used the antiskid cord clip, the shape constraining at the drag-line in cable saddle exit is become regular hexagon, make drag-line in cable saddle, reduce greatly with the contact surface of interior pipe, drag-line can contact fully relatively with epoxy mortar, the uniform relatively skid resistance of formation;
3, under the prerequisite of anchoring quantity of the same race, quality drag-line, can reduce the cable saddle size, reduce cost.
In the utility model cable saddle, because drag-line and epoxy mortar have enough big contact surface, assurance has enough big skid resistance, under the prerequisite of quantity of the same race, quality drag-line, the radial dimension of pipe can dwindle in the cable saddle, and along with dwindling of interior pipe, outer tube dwindles too, because reducing of whole cable saddle radial dimension makes Sarasota less in the weakening of cable saddle place intensity; While is owing to the cable saddle size reducing, cord clip is constrained to regular hexagon to drag-line, make the size of outsourcing PE pipe of supporting rope dwindle greatly, the cost of PE pipe can reduce greatly, the cost that reduces also can reduce greatly cable saddle of cable saddle size, make the cost of auxiliary equipment of whole drag-line reduce greatly, make the product of this type have more competitiveness.
