As shown in Figures 1 to 4, be provided by the present invention for support steel box-girder the preferred embodiment of temporary support one,
The temporary support includes 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 stud A
Space, pier stud A be used for steel box-girder B is permanently fixed.In the present embodiment, four tubing strings 1 are tubular pillar, and its bottom is equal
It is connected by expansion bolt (not shown) with basis, is easy to carry out dismounting recycling to tubular pillar.In four tubing strings 1
In, it is erected with some first crossbeams 2 being mutually detachably connected, some first crossbeams 2 between two adjacent upper ends of tubing string 1
It is H profile steel, H profile steel is enclosed jointly is set as a rectangular main frame 20, the upper end of main frame 20, which is fixed with, some is used for branch
Support steel box-girder B backbar 3.Specifically, interfixed between first crossbeam 2 and tubing string 1 by welding, it is ensured that first crossbeam 2
The stability being connected with tubing string 1, is fixedly connected between first crossbeam 2 and first crossbeam 2 by bolt 4, be easy to first crossbeam 2 with
It is detachably connected between first crossbeam 2, is easy to first crossbeam 2 to reuse and connect by adding the progress bolt 4 of first crossbeam 2
Connect, 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 box-girder B
Width demand, steel box-girder B is supported, it is low with cost, set up the good advantage of easy, time saving and stability.
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 constitute a triangular structure, meet above-mentioned interim branch
Support support steel box-girder B intensity requirement.
The embodiment of the present invention additionally provides a kind of construction method of temporary support as described above, and the construction method includes
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 enhances 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：
