Description
Technical Field
The invention relates to a saddle groove pressing device for a suspension bridge saddle, namely a pressing beam and an assembly structure thereof.
Background
In the structure of the suspension bridge, the integral design is based on the basic assumption that the main cable does not slide in the saddle groove of the cable saddle (comprising the main cable saddle and the loose cable saddle), so that the suspension bridge does not allow the main cable to slide in the saddle groove during the service process after the bridge is formed. According to the technical requirement of industry standard, in order to enable the main cable of the suspension bridge to achieve the anti-sliding effect in the cable saddle groove, a pressing device capable of applying downward pressure and increasing friction force to the main cable in the saddle groove is required to be arranged on the cable saddle head so as to achieve the anti-sliding effect of the main cable in the cable saddle groove.
Referring to fig. 1, the conventional saddle groove pressing device for a suspension bridge saddle is mainly composed of a pressing beam 1 and a rubber backing plate 2. The specific structural forms of the compression beam 1 are more, but not a specific structural form, but according to the matching structures of the compression beam and the cable saddle in various structural forms, the compression beam can be generally summarized as: the compression beam 1 has a left end connector, a middle pressing section and a right end connector in the transverse direction corresponding to the top structure of the saddle 3, the left end connector and the right end connector of the compression beam 1 are respectively connected and fixed at the top of the saddle 3 through a plurality of locking bolts, and the middle pressing section of the compression beam 1 spans the saddle groove of the saddle 3 and is matched with the saddle groove width outline of the saddle 3, and is usually capable of extending into the saddle groove and is positioned above each baffle 4 in the saddle groove. The rubber cushion plate 2 is an integral plate structure matched with the pressing section of the pressing beam 1, namely, the rubber cushion plate 2 is a strip-shaped structure matched with the saddle groove width profile of the cable saddle 3, and can cover all the partition plates 4 in the saddle groove along the saddle groove width in the up-down direction.
Referring to fig. 1, when the suspension bridge is constructed, the main cable strands 5 are erected in the respective channels in the saddle 3 (the saddle space divided by the partitions 4 in the saddle is the channel), so that the main cable strands 5 form a cable strand row in the corresponding channel of the saddle, the cable strand rows erected in the respective channels in the saddle are not equal in height direction based on the circular or nearly circular structure of the cross section of the main cable, and in order to enable the pressing force applied by the pressing device connected later to the top of the saddle 3 to act on the respective cable strand rows, the zinc filler 6 is required to be filled in part or all of the channels in the saddle, so that the filler (including the cable strand rows and the zinc filler 6) in the respective channels can be brought into direct pressing contact with the pressing device. In theory, the top surface of the filler in each tank way of the saddle groove needs to be flush or slightly higher than the top end of the partition board 4 in the saddle groove, and the top surfaces of the filler in each tank way of the saddle groove are on the same plane, so that the whole rubber backing plate 2 of the pressing device connected to the top of the cable saddle 3 can directly and effectively press the filler in each tank way, downward pressure is applied to the filler in each tank way, and meanwhile friction force is improved, and the main cable can achieve the anti-skid effect in the saddle groove of the cable saddle 3.
However, in actual operation, due to the unavoidable direct influence of factors such as diameter tolerance of main cable steel wire, dimensional tolerance of saddle groove and installation precision of on-site main cable strand, after each channel of saddle groove is finally filled, the top surfaces of all fillers are difficult to form a complete plane in saddle groove, so that the following three possible technical conditions are easy to appear to influence the application of the pressing force and friction force of the pressing device to the main cable in saddle groove:
in the first situation, referring to fig. 2, after the zinc filling blocks 6 in each tank way of the saddle groove are filled, the top surface height of the filling material in part or all tank ways is lower than the theoretical design value, namely, the top surface height of the filling material in part or all tank ways is lower than the top end of the partition plate 4, the rubber cushion plate 2 under the pressing beam 1 of the pressing device connected to the top of the cable saddle 3 is supported by the top end of the partition plate 4, namely, the rubber cushion plate 2 under the pressing beam 1 sits on the top end of the partition plate 4 without contacting with the filling material in the tank way with lower top surface height, so that a gap A is formed between the filling material in the tank way with lower top surface height and the rubber cushion plate 4, and the acting force of the pressing device on the filling material in each corresponding tank way is influenced by the existence of the gap A, so that the pressing force of the pressing device does not effectively act on the main cable, and the anti-skid effect is obviously not in place. Of course, this situation is solved in the industry, and it is common to fill the gap a with zinc fillers to eliminate the gap, so as to ensure that the fillers in each tank can be effectively contacted with the rubber pad 2 of the compacting device, but this measure is very complicated, and affects the normal construction period and increases the construction cost.
In the second situation, referring to fig. 3, after the zinc filling blocks 6 in each tank way of the saddle groove are filled, the height of the top surface of the filling material in part or all of the tank ways is higher than the theoretical design value, which forces the connection position of the pressing device at the top of the saddle 3 to rise, even if the rubber backing plate 2 of the pressing device is in full effective downward contact with the top surface of the filling material in each tank way, a gap B is formed between the bottom surfaces of the connectors at the left end and the right end of the pressing beam and the top surface of the saddle 3, and the stability and the reliability of the connection of the pressing device on the saddle are affected by the existence of the gap B, so that the anti-skid effect is also affected; in other cases, under the condition that the heights of the top surfaces of the filling materials in part of the tank ways are too high, the top surfaces of the filling materials in all the tank ways in the saddle tank cannot form a complete plane, so that the rubber backing plate 4 of the compacting device can be influenced to be in effective pressing contact with the top surfaces of all the filling materials in the tank ways, the pressing force of the compacting device can not effectively act on the main cable, and the anti-skid effect is obviously not in place.
In the third condition, see fig. 4, the combination of the first condition and the second condition is that the top surface height of the tank filler in the saddle tank is lower than the theoretical design value, and the top surface height of the tank filler in the other portion is higher than the theoretical design value, and the bad result is the superposition of the first condition and the second condition, see the first condition and the second condition, and will not be repeated here.
In summary, the conventional saddle groove pressing device for the suspension bridge saddle is integrally and synchronously pressed, so that when the heights of the top surfaces of the fillers in the grooves below cannot be in the same plane, the rubber backing plate cannot form effective pressing contact with the top surfaces of the fillers in the saddle groove, so that the pressing force of the pressing device cannot be effectively applied to the main cable, the anti-skidding effect of the pressing device on the main cable in the saddle groove is not in place, and the construction technical difficulty is increased.
