Reliably；2. by setting polylith vertical plate or level board in saddle groove, main push-towing rope anti-slide performance is improved by increase rubbing surface.And
In fact, because the anti-slide performance of main cable strand has larger difference from top to bottom, top layer strand is because of antiskid frictional force minimum
It can slide first, therefore which can not effectively make up the antiskid " short slab " of top layer strand, therefore, it is difficult to ensure that the entirety of main push-towing rope resists
Sliding security；3. by tower rigidity in weakening, the main push-towing rope power that reduction is likely to occur is poor, so that evade the sliding risk of main push-towing rope, but
This processing mode can reduce full bridge structure rigidity and wind resisting stability, while construction costs can be also dramatically increased, therefore it is this
The practice also not a kind of favourable solution.

The moving up and down friction clamping plate of cooperation and in the neck 6 that can not vertically move；
Two described secondary anti-skid devices are symmetrically disposed in the two ends on main saddle top, anti-skid device include lower plate 7,
Train wheel bridge 8 and the fastening bolt 9 for coupling lower plate and train wheel bridge；The thickness and upper and lower surface and friction clamp of lower plate 7
Plate is consistent；The inner section shape of train wheel bridge 8 is consistent with the arrangement of upper strata strand 3；The end face of lower plate 7 and train wheel bridge 8 with master
Saddle is held out against, and leaves the hole for being available for fastening bolt 9 to pass through；Upper strata strand is clamped by fastening bolt 9 and prevents it from indulging
To sliding.
Further, the quantity of described upper strata strand 3 is less than the quantity of lower floor's strand 2.
Further, friction clamping plate whole process in two secondary anti-skid devices are interval is arranged on upper strata strand 2 and lower floor's rope
Between stock 3.Friction clamping plate at least has four.
The beneficial effects of the invention are as follows：The present invention compared with prior art, by setting friction clamping plate, can provide for main push-towing rope
Extra antiskid rubbing surface, makes full use of the immense pressure that strand itself is produced on plate, to effectively improve lower floor's strand with this
Antiskid level；By setting up anti-skid device, top layer strand can be avoided because of anti-slide performance is weak and slides first risk.Cause
This, the processing mode of above-mentioned layering antiskid can be obviously improved the overall antiskid performance of main push-towing rope, with clearly defined objective, stress of setting up defences
The advantages of relation is simple, operability is good, if empty for the selection that middle tower rigidity in multi-span suspension bridges structure, can be substantially improved
Between, it thus can optimize the behavior of full-bridge stress and save substantial amounts of engineering cost.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
In the main push-towing rope layering anti-skid construction embodiment shown in Fig. 1~Fig. 5, some pieces are provided with along the longitudinal direction of main saddle saddle groove
Friction clamping plate 1, so that main cable strand is divided into lower floor's strand 2 and upper strata strand 3.The upper and lower surface of friction clamping plate 1 is both designed as
Arcwall face, can be such that main cable strand is in close contact with friction clamping plate 1.The both sides of each piece of friction clamping plate 1 are equipped with tenon 4, and tenon 4 can
Moved up and down along the neck 6 on main saddle side wall 5, so as to the pressure transmission that acts on upper strata strand 3 on friction clamping plate 1 extremely
