Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in fig. 1~fig. 5, a kind of landscape suspension bridge, including bridge tower, the main push-towing rope 1 being set up on bridge tower, bent cap 4, erection
In girder, anchorage system 3 and sunpender 9 on bent cap 4；The longeron 2 parallel with girder longitudinal central axis line is arranged in 1 lower section of main push-towing rope, and
It is connect with longeron 2 by more sunpenders 9；2 middle part of longeron and 5 vertical connection of crossbeam being extend horizontally away from 4 tail end of bent cap, longeron
2 being partially embedded in bridge tower by bridge tower, 2 both ends of longeron and anchorage system 3 are connect after pouring integrally with 1 both ends of main push-towing rope；
The anchorage system 3 includes abutment cushion cap 15, positioned at the anchorage block 18 of 15 upper outer of abutment cushion cap and positioned at abutment cushion cap
The abutment sidewall 14 of 15 tops inside.
Longeron 2 include two open ends backwards to and the channel steel that is mutually parallel, sunpender 9 pass through positioned at 2 left and right sides of longeron
Steel plate 11 and bolt 8 are fixed between two channel steels, and pass through the upper padding plate 6, lower bolster 7 and nut positioned at 2 upper and lower of longeron
10 fixed derrick, 9 lower end；5 one end of crossbeam and 11 vertical welding of steel plate, the other end are passed perpendicularly through through reinforcing bar 1, run through steel
Muscle 1 is poured by pre-buried in bent cap 4.
The bolt 8 passes perpendicularly through 9 axis of sunpender.
The tail end of longeron 2 is passed through through reinforcing bar 2 13, is poured in anchorage system 3 by pre-buried through reinforcing bar 2 13.
The crossbeam 5 is made of multigroup I-steel.
The anchorage block 18 includes anchorage block body, anchorage 16, bellows 17 and is located at anchorage block body internal reservation
Through hole 19, the anchorage 16 is used to be secured across the main push-towing rope 1 of through hole 19 and bellows 17, and the bellows 17 is used
In package main push-towing rope 1.
9 upper end of sunpender is fixed on by cord clip on main push-towing rope 1.
A method of decorative suspended-cable structure is installed on above-mentioned landscape suspension bridge, is included the following steps：
S1:It pours 5 one end of crossbeam is pre-buried in bent cap 4, it is another that the side channel steel of longeron 2 is then welded on crossbeam 5
End installs the other side channel steel of longeron 2, sunpender 9 is stuck between two channel steels；
S2:Construct bridge tower and anchorage structures, longeron 2 be partially embedded in by bridge tower in bridge tower, by longeron 2 both ends with
Anchorage system 3 pours integrally；
S3:Main push-towing rope 1 is erected on bridge tower, in place, 1 both ends of main push-towing rope are anchored on anchorage system 3 for tensioning main push-towing rope 1；
S4:It is symmetrically installed sunpender 9, and 9 lower end of fixed derrick from bridge tower toward both ends.
Anchorage system 3 and abutment sidewall 14, the steel bar overall binding in construction work of abutment cushion cap 15, one-piece casting coagulation
The bellows 17 of earth forming, package main push-towing rope 1 passes through through hole 19,1 end of main push-towing rope to anchor and fix by anchorage 16, final main push-towing rope
1 pulling force is undertaken by 3 its own gravity of anchorage system.
Since the suspended-cable structure of the present invention belongs to main bridge decorative parts, be not involved in the main stress of main bridge, suspended-cable structure with
The separation of main bridge is individually designed, and for 9 anchoring lower ends of sunpender on longeron 2, longeron 2 is partially embedded in bridge tower, anchor by bridge tower, abutment
In ingot structure, crossbeam 5, which is supported in, to be embedded on 4 beam-ends of bent cap.It need to be accurately controlled in bridge tower, abutment, pier cap beam construction vertical
The embedding absolute altitude of beam 2, crossbeam 5,2 upper hanger 9 of longeron reserve hole site and also answer setting-out accurate.It is needed in the production process in main push-towing rope
Accurate marker is carried out on 1, then calculates the absolute altitude at each control point, and jack can be used in anchorage zone tensioning in the adjustment of main push-towing rope 1.
The vertical distribution for first adjusting main span span centre cable is completed to fix at cable saddle.The label on main push-towing rope 1 be should refer to when adjustment to ensure rope
Adjusting range.Main span adjust after, end bay according to design provide Suo Li by 1 tensioning of main push-towing rope in place.Sunpender is in installing Cable-clamp
It installs immediately after the completion.Small-sized sunpender is using manually installed, and large-scale sunpender is using crane cooperation installation.9 in-site installation of sunpender needs
Want tensioning.The installation and tensioning of sunpender 9 carry out successively from bridge tower toward both sides, and both sides bridge tower hanger erection tensioning needs symmetrical equilibrium to apply
Work ensures 9 apparent perpendicular shape of sunpender and main cable alignment.First time tensioning applies 1/4 design power by each sunpender 9
Temporary locking, second of sequence is identical as first time, complete by design power tensioning, then detects the actual loading of each sunpender 9,
Finally specifically each sunpender 9 is finely adjusted according to design power.For two sunpenders 9 close to 1 anchor point of main push-towing rope, due to hanging
Pole length is shorter, using push-and-pull rod.The theoretical anchor point of anchorage block 18 answers setting-out accurate, and absolute altitude must accurately control.It waits mixing
Solidifying soil intensity reaches 100%, can install main push-towing rope.It is pre-buried accurate that anchorage 16 etc. at 1 anchoring of main push-towing rope is answered, and ensures in stretching process
Cable is always positioned at the center of reserved bellows 17, and with bar-mat reinforcement spot welding around.
Sunpender 9 is fixed on longeron 2 and crossbeam 5 by anchoring process through the invention, rather than sunpender 9 is directly fixed
In on beam body flange plate, to reduce the adverse effect to beam body, abutment cushion cap 15, anchorage block 18 and abutment sidewall 14 are designed
It is structure as a whole, 1 pulling force of main push-towing rope is passed to by entire anchor system 3 by anchorage block 18, anchor system 3 again passes entire load
It is handed to abutment sidewall 14 and abutment cushion cap 15, abutment sidewall 14 and abutment cushion cap 15 provide sufficiently large resistance to balance main push-towing rope
1 huge pulling force prevents bridge tower from tilting and even collapses, to play the anchorage effect of balance 1 pulling force of main push-towing rope, makes full use of and finish
Its own gravity of structure avoids construction large volume anchorage structures from improving the stability and durability of structure to save cost.
