The pre-embedded construction method all same of the pre-embedded bolt group of all steel column fixations in the steel structure framework；
When carrying out Embedment Construction to the pre-embedded bolt group of any steel column fixation, process is as follows：
Step 1: billet determines：The billet installed to the pre-embedded bolt group is determined, and obtains the pre-embedded bolt
The installed billet of group is the first billet or the second billet；
Step 2: bolt mounting holes group determines：According to the billet definitive result obtained in step 1, to the pre-embedded bolt
The bolt mounting holes group of group is determined：When showing that billet that the pre-embedded bolt group is installed is the first billet in step 1
When, show that the bolt mounting holes group that the pre-embedded bolt group is installed is the upper inside bolt mounting holes group and the lower inside spiral shell
Bolt mounting hole group；When the billet for showing that the pre-embedded bolt group is installed in step 1 is the second billet, show that this is pre-buried
The bolt mounting holes group that bolt group is installed is the upper outside bolt mounting holes group and the lower outside bolt mounting holes group；
Step 3: surveying setting-out：Wait for steel reinforcement cage binding set in reinforced concrete foundation residing for the pre-embedded bolt group
Before after the completion and carrying out concreting to reinforced concrete foundation, to multiple lower margins that need to construct in the pre-embedded bolt group
Pre-buried position and pre-buried height of the bolt on reinforced concrete foundation measure unwrapping wire respectively；
Step 4: mold is placed and foundation bolt is tentatively installed：It is obtained according to surveying setting-out in step 3 multiple described
Need to construct the pre-buried position of foundation bolt, and the molding embedding anchor bolts construction mould will be pre-machined and be positioned over step 3
Described on steel reinforcement cage；Multiple foundation bolts that need to construct tentatively are installed again；
When tentatively being installed to the foundation bolt that need to construct described in any one, according to the bolt mounting holes obtained in step 2
Group definitive result is installed：When showing that bolt mounting holes group that the pre-embedded bolt group is installed is the upper inside in step 2
When bolt mounting holes group and the lower inside bolt mounting holes group, from top to bottom by the foundation bolt that need to construct from upper level board
It is pierced by with the first bolt mounting holes opened on lower horizontal board；When the bolt peace for showing that the pre-embedded bolt group is installed in step 2
