The purpose of this utility model is realized by following technical proposals:
A kind of 0# sections of bracket combination formula pre-pressing systems of cantilever rigid frame-continuous girder, if pier shaft is placed per lateral bracket top surface direction across bridge
Dry group upper beam, and pier shaft both sides upper beam quantity is consistent, every upper beam passes through pressurization by several drawstrings and the pre-buried drawstring of cushion cap
System is connected as one, and compression system includes central sill, underbeam and jack, and underbeam is connect by drawstring with upper beam, and central sill is set to
Above underbeam, it is connect with the pre-buried drawstring of cushion cap by very heavy top support, central sill between central sill and underbeam.
Alternatively, the upper beam, drawstring and compression system of pier shaft both sides are symmetrical arranged.
Alternatively, jack is set to the centre position of central sill and underbeam, and the drawstring of both sides is symmetrical arranged.
Alternatively, upper, middle and lower beam is 588 shaped steel of Two bors d's oeuveres work.
Alternatively, drawstring is finish rolling deformed bar.
Alternatively, pier shaft places two groups of 588 shaped steel of Two bors d's oeuveres work, spacing 1.2m, every group of type per lateral bracket top surface direction across bridge
Steel is connected as one with the pre-buried finish rolling deformed bar of cushion cap by compression system by 4 32 finish rolling deformed bars of Φ, Mei Gejia
A jack is arranged in pressure system.
The aforementioned main scheme of the utility model and its each further selection scheme can be freely combined to form multiple schemes,
The scheme that can be used and be claimed for the utility model;And the utility model,(Each non conflicting selection)Between selection and
It can also be freely combined between other selections.Those skilled in the art are after understanding the present invention program according to the prior art and public affairs
Know that common sense can be illustrated there are many combination, is the claimed technical solution of the utility model, does not do exhaustion herein.
The beneficial effects of the utility model:It is poor to overcome traditional pre-compressed effect, precompressed weight is insufficient, and risk factor is high, at
The defects of this height, construction is inconvenient, and waste of material is serious.Easy using new-type pre-pressing system, versatile, stability is high, follows
Ring utilization rate is high, and at low cost, Saving in time costs is apparent.

Specific implementation mode
The utility model is further described with reference to specific embodiments and the drawings.
With reference to shown in figure 1,2, a kind of 0# sections of bracket combination formula pre-pressing systems of cantilever rigid frame-continuous girder, pier shaft 1 is per lateral bracket 2
Top surface direction across bridge places several groups upper beam 3, and pier shaft 1 both sides upper beam, 3 quantity are consistent, every upper beam 3 by several drawstrings 4 with
5 pre-buried drawstring 4 of cushion cap is connected as one by compression system 6, and compression system 6 includes central sill 7, underbeam 8 and jack 9, underbeam 8
Connect with upper beam 3 by drawstring 4, central sill 7 is set to the top of underbeam 8, is supported by jack 9 between central sill 7 and underbeam 8, central sill 7 with
5 pre-buried drawstring 4 of cushion cap connects.It is preferred that the upper beam 3 of 1 both sides of pier shaft, drawstring 4 and compression system 6 are symmetrical arranged, jack 9 is set to
The drawstring 4 in the centre position of central sill 7 and underbeam 8, both sides is symmetrical arranged.
As an example, certain river grand bridge, in northern access bridge 100m continuous rigid frames construction, using combined type pre-pressing system, pier
1 height 35m of body, pier shaft 1 place the upper beam 3 of two groups of 588 shaped steel of Two bors d's oeuveres work, two groups of 3 spacing of upper beam per 2 top surface direction across bridge of lateral bracket
1.2m, every group of upper beam 3 are logical by the drawstring 4 of 4 32 finish rolling deformed bars of Φ and the drawstring 4 of 5 pre-buried finish rolling deformed bar of cushion cap
System 6 is overpressurized to be connected as one, jack 9 is that power core is mounted between the central sill 7 and underbeam 8 of two groups of Two bors d's oeuveres works 588,
It checks whether the drawstring 4 of 8 finish rolling deformed bars is vertical simultaneously when installation and tenses stress, then pressurize, when pressurization requires 4 thousand
9 synchronous averagings of jin top, synchronzed press, according to 100% → total load head of 60% → total load head of construction total load head 120% → quiet stop
1h measure it is quiet after vertical and transversely deforming value → third level load stop starting load shedding for 24 hours, and observe flexible deformation value step by step.
Both sides symmetrically carry out when pressurization, and 9 corresponding pressure on top surface of each jack is 60%, 100%, 120% and avoids holder inclined
Heart stress, load should be substantially close with beam body load assignment.The deformation that observation holder is needed in loading procedure, found the abnormal situation and want
Stop preloading immediately, ascertain the reason and can continue precompressed after adopting an effective measure.Precompressed is another in the same way for the complete side of precompressed
Side, can also both sides synchronization progress.
By such pre-pressing system precompressed, workload when precompressed is reduced, bracket pre-compressed effect is improved, strengthens high pier
The safety of temporary structure when construction, and install convenient, waste of material is few, and cyclic utilization rate is high.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
