Abstract
The invention relates to a connecting structure for a cable clamp and a suspender of a suspension bridge. The structure comprises the suspender, the cable clamp, a pressure-beating nut and a pressure-bearing rib plate, wherein the suspender comprises a suspension cable and an outer steel tube; the pressure-bearing rib plate equipped with a horizontal pressure-bearing face is firmly disposed on the upper end of the outer steel tube, a fork lug equipped with threads is disposed on the upper part of the suspension cable, and the pressure-bearing nut is in a threaded connection with the fork lug and pressed against and coordinated with the pressure-bearing rib plate; and the pressure-bearing nut is adjusted to fit the length of the outer steel tube, so that water leakage can be prevented. The connecting structure for the cable clamp and the suspender of the suspension bridge provided by the invention is improved; a pure welding manner adopted in the prior art is changed into the manner of mutual pressing and coordination of the pressure-bearing nut and the pressure-bearing rib plate; connection positions of the pressure-bearing nut and the fork lug can be adjusted, so that length tolerance of the outer steel tube can be greatly increased, and processing becomes more convenient; and force bearing of the outer steel tube is greatly simplified, so that the suspension cable is prevented from being corroded due to rainwater infiltration which is caused by cracking of the outer steel tube generated from stress changes.
Description
Technical field
The present invention relates to suspension bridge, specifically, be a kind of cord clip of suspension bridge and the syndeton of suspension rod, belong to suspension bridge technical field.
Background technology
See Fig. 1, in bridge technology field, main bridge dead load to be mainly transformed into the process of main push-towing rope by system transform by support by carrying out stretch-draw repeatedly to main push-towing rope and suspension rod, be the key link in bridge construction process.And the transmission of power is mainly realized by cord clip between main push-towing rope and hoist cable.
See Fig. 2, suspension rod 4 comprises hoist cable 4b and outside steel pipe 4a, the Conventional attachment methods of existing cord clip and hoist cable and outside steel pipe is for welding, common way first adopts screw 6 to be connected with cord clip otic placode 2a by the floor 5 of hyperboloid structure, then be welded and fixed with outside steel pipe 4a and cord clip otic placode 2a by floor 5.The hoist cable 4b of outside steel pipe 4a inside is connected by hinge with cord clip.
The syndeton of the cord clip suspension rod of this form has the shortcoming of the following aspects: 1. hoist cable outside steel pipe length cutting stock precision requires high.Main push-towing rope is connected with hoist cable and outside steel pipe by cord clip, and whether accurate the length of hoist cable outside steel pipe is will directly have influence on the linear of main push-towing rope, and then it is stressed to have influence on whole bridge construction; 2. floor difficulty of processing is high.Floor shape is Space Double curved surface, requires to fit tightly with cord clip otic placode, otherwise easily occurs phenomenons such as leaking; 3. the stressed complexity of hoist cable outside steel pipe, wayward.In system conversion process, main push-towing rope and hoist cable interlock stretch-draw, by the stress causing hoist cable outside steel pipe to produce stretch bending or press-bending, unfavorable to behavior of members under loading.
Summary of the invention
The present invention seeks to: 1. reduce difficulty of processing, save processing cost, reduce process time.In prior art, suspension rod outside steel pipe length must prepare to put in place, to guarantee that main cable alignment is accurate; Floor shape is the Space Double curved surface matched with cord clip otic placode, with true closely knit waterproof.It is very large that these require all to cause steel beam column difficulty of processing, takes time and effort; 2. cable-cabin structure is simplified stressed.In prior art, the connected mode of cord clip and suspension rod is for welding, and in system conversion process, main push-towing rope and hoist cable interlock stretch-draw, make the stressed complexity of whole suspension rod system, are unfavorable for the quality control in engineering construction.
The present invention takes following technical scheme:
The cord clip of suspension bridge and a syndeton for suspension rod, is characterized in that: comprise suspension rod 4, cord clip 2, fork ear 3a, pressure-bearing nut 7, pressure-bearing floor 8; Described suspension rod comprises hoist cable 4b, outside steel pipe 4a; Described outside steel pipe 4a upper end is fixed and is provided with the pressure-bearing floor 8 with land of mold, and the top of hoist cable 4b is connected with car threaded fork ear 3a, and described pressure-bearing nut 7 is threaded onto on fork ear 3a, and with pressure-bearing floor 8 compression fit; Regulate described pressure-bearing nut 7, can regulate and adapt with the length of outside steel pipe 4a.
The feature of the technical program is: improve the cord clip of suspension bridge and suspension rod syndeton, the mode of the pure welding adopted in prior art is changed into the mode by pressure-bearing nut and the mutual compression fit of pressure-bearing floor, by the relative position regulating pressure-bearing nut to be connected with fork ear, compression degree can be regulated.The technical program avoids the manufacturing procedure connecting floor, improves outside steel pipe length tolerance, has saved processing cost, saved process time; Meanwhile, outside steel pipe and cord clip otic placode are separated, and simplify the structure stressed, avoid in system conversion process and cause due to STRESS VARIATION outside steel pipe to break, so that rainwater infiltrates hoist cable is got rusty the generation of phenomenon.
Further, described pressure-bearing floor 8 is weldingly fixed on described outside steel pipe 4a.
Further, described pressure-bearing floor 8 is made up of square plate and 4 stiffeners, and stiffener is arranged symmetrically.
Further, described pressure-bearing nut 7 is round nut.
Beneficial effect of the present invention is:
1) suspension bridge suspention architecture is simplified stressed.Because hoist cable outside steel pipe and cord clip otic placode are separated, make structure stress clearer and more definite.By adjustment pressure-bearing nut, hoist cable outside steel pipe internal force effectively can be discharged within safe range.
2) hoist cable outside steel pipe processing length error is easy to control.Because pressure-bearing nut can move up and down adjustment, therefore hoist cable outside steel pipe processing length error requirements can reduce greatly, is not only easy to processing, also saves a large amount of processing charges simultaneously;
3) waterproof.Because pressure exists, pressure-bearing nut is combined closely with floor all the time, can prevent rainwater from infiltrating, avoid hoist cable corrosion;
4) constructability.Because the connection of hoist cable, outside steel pipe and cord clip is realized by moveable pressure-bearing nut, therefore can avoid being similar to welding job loaded down with trivial details in Conventional attachment methods construction, both accelerate construction progress, and also saved labour cost simultaneously.
