Embodiment
More detailed illustrate is carried out to present disclosure below：
It is an object of the invention to the construction method that invention superposed column pre-embedded anchoring bolts are vacantly positioned, it is ensured that foundation bolt is fixed
The construction quality of position, so as to overcome foundation bolt to be accurately positioned the big mass defect of deviation.
1st, hanging line setting
Axis pilot measurement is bound on slab form using BIM modeling auxiliary total powerstation axial line control points, also with principles above
By in another azimuth axis also pilot measurement to template, crossing point of axes is made in bracing wire, and with total Station Measured, this space coordinate put is
For superposed column built-in fitting foundation bolt centre point spatial value.
2nd, foundation bolt support makes
Embedding anchor bolts part is made up of band steel frame, the vertical angle steel of level and diagonal brace angle steel up and down, and foundation bolt support is above and below
Band steel frame is connected by the wide band steels of 6mm thickness 80mm（Depending on size of the band steel width of frame according to superposed column）, beaten up and down in the middle part of band steel frame
