In order to achieve the above object, the present invention is realized in：
A kind of support lifted for steel structural overhead, it includes column, crossbeam, brace, support bracket, lifter, connection wirerope, top joist and bottom joist；Column arranges that column bottom plate is arranged on column bottom vertically, and column is welded on the top of building post by column bottom plate；Crossbeam and support bracket are located at the top and middle part of column respectively, and brace is supported between crossbeam and bracket；Top joist is located at cross rail top and is fixedly connected with crossbeam top plate, and transverse stiffener is provided between top joist and crossbeam；Bottom joist is connected by transverse stiffener with elevated structure；Top joist and bottom joist are all symmetrically provided with through hole in crossbeam both sides, and top joist is corresponding with the through hole on the joist of bottom, and connection wirerope is worn with being connected top joist and bottom joist in through hole.
The application method of the support, including
Step 1：Holder device is welded on building iron column top by the column bottom plate of bottom, wherein, when it is concrete column to build post, then it is welded on the pre-embedded steel slab at the top of it；
Step 2：Two hydraulic rockshafts are set on the joist of top；
Step 3：Bottom joist is welded on to the bottom of elevated structure；
Step 4：Connection wirerope is installed, structure is lifted to design attitude and installed using wirerope is connected；
Step 5：Slow unloading, bottom joist is separated simultaneously with elevated structure；
Step 6：Holder device is cut off, lifting construction is completed.
Two table lifters can be set in this holder device, and are held in the palm by bottom joist and hold elevated structure, to reach that suitable suspension centre is arranged on the purpose of elevated structure bottom, it has easy construction, it is safe and stable the characteristics of.
