Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in Figures 1 to 4, it is that the temporary support one provided by the utility model for being used to support steel box-girder is preferably implemented
Example, the temporary support include four tubing strings 1 on the basis of being fixed on, and four tubing strings 1 enclose jointly to be set as one and be easy to accommodating pier
Post A space, pier stud A are used to be permanently fixed steel box-girder B.In the present embodiment, four tubing strings 1 are tubular pillar, its bottom
End is connected by expansion bolt (not shown) with basis, is easy to carry out dismounting recycling to tubular pillar.In four pipes
In post 1, some first crossbeams 2 being mutually detachably connected are erected between adjacent two upper ends of tubing string 1, some first is horizontal
Beam 2 is H profile steel, and H profile steel is enclosed jointly is set as a rectangular main frame 20, and the upper end of main frame 20 is fixed with some be used for
Support steel box-girder B backbar 3.Specifically, interfixed between first crossbeam 2 and tubing string 1 by welding, ensure first crossbeam
2 stability being connected with tubing string 1, are fixedly connected between first crossbeam 2 and first crossbeam 2 by bolt 4, are easy to first crossbeam 2
It is detachably connected between first crossbeam 2, is easy to first crossbeam 2 to reuse and carries out bolt 4 by adding first crossbeam 2
Connection, so as to increase the length of main frame 20, some backbars 3 are evenly distributed in the surrounding of main frame 20, with according to steel case
Beam B width demand, is supported to steel box-girder B, has cost low, sets up the advantages of easy, time saving and stability is good.
In above-described embodiment, in order to further increase the stability of four tubing strings 1, in four tubing strings 1, adjacent tubing string
Some second cross beams 5 being mutually detachably connected are erected between 1 lower end.Specifically, second cross beam 5 is H profile steel, second cross beam
Interfixed, be fixedly connected between second cross beam 5 and second cross beam 5 by bolt 4, so as to right by welding between 5 and tubing string 1
Second cross beam 5 is reused.In addition, it is welded between the first crossbeam 2 of the upper end of tubing string 1 and the tube wall of tubing string 1 and leads to
Cross reinforcement 6 to be welded and fixed, first crossbeam 2, reinforcement 6 and tubing string 1 form a triangular structure, meet above-mentioned interim branch
Support support steel box-girder B intensity requirement.
The construction method of above-mentioned temporary support comprises the following steps：
S1, according to site operation situation and the steel box-girder B width situations to be supported, by the installation position of four tubing strings 1
Put structure and be set as a rectangle, and basis is fixed in the bottom of four tubing strings 1 by expansion bolt；And in four tubing strings 1
In adjacent two lower ends of tubing string 1 be welded and fixed second cross beam 5, connected between second cross beam 5 and second cross beam 5 by bolt 4
Connect, to strengthen the stability of the temporary support.
S2, four upper ends of tubing string 1 first crossbeam 2 is welded and fixed, passed through between first crossbeam 2 and first crossbeam 2
Bolt 4 is fixedly connected, to meet the width demand of steel box-girder B width.And in the first crossbeam 2 of the every upper end of tubing string 1 and this
Reinforcement of weld beam 6 between the tube wall of root tubing string 1, further enhance the stability of the temporary support.
S3, in some backbars 3 of the upper end vertical welding of first crossbeam 1, for temporary support steel box-girder.
Above-mentioned temporary support has the following advantages that：
(1) H profile steel and tubular pillar of wide material sources can be made full use of, can live processing and fabricating, save construction duration.
(2) welding and bolt connecting mode are passed through, you can be rapidly completed installation and dismounting, it is steady on the one hand can to increase connection
Solidity, on the other hand the temporary support can be dismounted, facilitate entrucking to be reused.
(3) bolt connection is carried out, between two second cross beams by adding first crossbeam between two first crossbeams
Bolt connection is carried out by adding second cross beam, suitable for being supported to the steel box-girder in different wide faces.
(4) for supporting higher steel box-girder, tubular pillar can save traditional institute according to required random length is taken
With the waste of multiple rows of Bailey bracket material, cost is reduced.
(5) backbar being fixed on main frame can coordinate the Secondary Control correction of jack progress height.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
