The 4th root post the 4, the 5th root post 5, six roots of sensation column the 6, the 7th root post the 7, the tenth root post the 10, the 12nd root post the 12, the 13rd root post the 13, the 14th root post the 14 and the 18th H profile steel the 18, the 19th H profile steel the 19, the 21st H profile steel the 21, the 22nd H profile steel 22 is utilized to control the position of stage casing, both sides column；
Six roots of sensation column the 6, the 7th root post the 7, the 8th root post the 8, the tenth root post the 10, the 11st root post the 11, the 12nd root post 12 column and the 18th H profile steel the 18, the 22nd H profile steel 22 is utilized to control the position of hypomere column；
The 8th root post the 8, the 9th root post the 9, the 11st root post 11 column and the 17th H profile steel 17 is utilized to control the position of lower half circular beam；
Step 3, is positioned over group on smooth place mold, if the space is insufficient smooth can ground lay steel plate；
Step 4, is all that as shown below point 8 sections transports are to scene when hydraulic press frame transports job site；
Hydraulic press frame transports job site and is placed in group to mold front；Putting position is followed successively by from front to back: upper half circular beam, lower half circular beam, epimere column, hypomere column and stage casing column；
Step 5, slings upper half circular beam hydraulic pressure straddle truck and is placed on group on mold, the level of beam to be ensured during lifting；
Step 6, by epimere column with hydraulic pressure gantry crane lifting to group on mold；
Step 7, by stage casing column with hydraulic pressure gantry crane lifting to group on mold；
Step 8, by hypomere column with hydraulic pressure gantry crane lifting to group on mold；
Step 9, by lower half circular beam with hydraulic pressure gantry crane lifting to group on mold.
Group to process in the middle of the gap that has only to adjust between each section of beam the most permissible；Use group mold is carried out the group of frame to compare use cushion block the most directly organize right, the most a lot of to the quality control of frame group pair, and efficiency of construction is higher.
130mm*130mm*240mm cushion block is installed at described column top.
Described column specification is:: the H profile steel of HW250*250mm, height is 500mm.
