Beam technical field of construction.
Background technology
In existing suspension bridge bridge construction, main push-towing rope is typically made up of many strands, takes partly accepting and partly rejecting between multiply
Principle set up when, strand section is non-round, voidage is big, it is impossible to meet install cord clip needs.A kind of instrument is needed for this
Loose strand is tightened up the circular cross-section for design needs and reaches voidage and is required.When typically adopting large-scale cable compacting machine,
Due to complex structure, cable compacting machine limited amount（General every only 2, bridge）Tight cable efficiency is low, and tight cable out-of-roundness difference is difficult to meet design
Need.Conventional cable compacting machine is not suitable for duration nervous suspension bridge main cable construction.
The content of the invention
Proposed by the present invention is a kind of tight cable tool structure of main rope of suspension bridge and design cycle, and its purpose is intended to using steel structure
Upper and lower two parts oval structure made by part, by jack tension upper lower half circle is tightened up, and reaches the voidage that design needs,
Simultaneously out-of-roundness reaches control well, facilitates follow-up installing Cable-clamp.
The technical solution of the present invention：
The tight cable tool structure of main rope of suspension bridge, its structure is upper semi-circle bitt compressor 1, lower half circle bitt compressor 2, tight cable distribution beam
3rd, tension rod 4,30t jack 5 are arranged on main push-towing rope 6, wherein being 30t jack between tight cable distribution beam 3 and lower half circle bitt compressor 2
5；Tensioning tension rod 4 has the gap of 1 ~ 2mm tightening up the section of main push-towing rope 6 between upper semi-circle bitt compressor 1 and lower half circle bitt compressor 2.
The method for designing of the tight cable tool structure of main rope of suspension bridge, comprises the steps：
1）Upper semi-circle bitt compressor 1 is installed on the main push-towing rope of original state；
2）Tension rod 4 and top nut are installed, then lower half circle bitt compressor 2 and intermediate nut are installed, tight cable distribution is finally installed
Beam 3 and lower nuts；
3）30t jack 5 are installed, the section of main push-towing rope 6 is tightened up by jack tension tension rod, until reaching design needs
Section voidage；Because the radius of bitt compressor is calculated according to the voidage that design needs, the out-of-roundness of rear main push-towing rope 6 is tightened up
Automatically design needs are met；
4）Main push-towing rope section is fixed with strap, tight cable tool structure is removed and is moved on to next main push-towing rope section operation.
Advantages of the present invention：Using this kind of tight cable frock, many operations can be realized with many sets of little cost manufacture, dispersion construction
Construct simultaneously in face；It is simultaneously simple for structure, it is easy to operation, tight cable speed is fast；Using Manual tightening, control out-of-roundness can be in real time measured
And voidage, tight cable quality is easily controlled.Low cost when this tight cable frock is constructed, it is fast and convenient, it is safe and reliable, with larger
Promotional value.
Description of the drawings
Accompanying drawing 1 is the tight cable frock general assembly drawing of main rope of suspension bridge.
Fig. 2-1 is the schematic diagram that upper semi-circle bitt compressor is installed on main push-towing rope.
Insert for Fig. 2-2 pair and lower half circle tightener is installed, finish rolling deformed bar is penetrated, the schematic diagram that two ends are attached the names of pre-determined candidates.
Fig. 2-3 installs reaction beam and jack, installs the schematic diagram of reaction beam back nut.
Main push-towing rope is tightened up in Fig. 2-4 jack finish rolling deformed bar tensioning, until the porosity for needing, is fixed with bailing band
After loosen jack, moving on to next place carries out the schematic diagram of tight cable work.
In figure 1 is upper semi-circle bitt compressor, 2 is lower half circle bitt compressor, 3 is tight cable distribution beam, 4 is tension rod, 5 is 30t
Jack, 6 be main push-towing rope, 7 be nut.
Specific embodiment
Control Fig. 1, the tight cable frock of main rope of suspension bridge, its structure is upper semi-circle bitt compressor 1, lower half circle bitt compressor 2, tight cable point
It is arranged on main push-towing rope 6, wherein being 30t thousand between tight cable distribution beam 3 and lower half circle bitt compressor 2 with beam 3, tension rod 4,30t jack 5
Jin top 5；Tensioning tension rod 4 has 1 ~ 2mm's tightening up the section of main push-towing rope 6 between upper semi-circle bitt compressor 1 and lower half circle bitt compressor 2
Gap.
Control accompanying drawing 2-1,2-2,2-3,2-4, the method for designing of the tight cable tool structure of main rope of suspension bridge, including following step
Suddenly：
1）Upper semi-circle bitt compressor 1 is installed on the main push-towing rope of original state；
