Described each connector length L is identical, and the scope of L is 200-300mm.
Large-scale steel structure pedestal embedded part localization method, the method comprises the steps:
1) make location-plate, according to diameter and the relative position of the pedestal embedded part bolt of pre-installation location, get thickness more than or equal to the steel plate of 20mm, boring makes the hole on the steel plate match with the pedestal embedded part bolt of pre-determined bit thereon;
2) lower floor's reinforcing bar of large-scale steel structure pedestal embedded part is installed, according to the pedestal embedded part design of the large-scale steel structure of pre-installation, in foundation ditch, is laid and colligation lower floor reinforcing bar;
3) connector is welded on the location-plate, utilizes level gauge to guarantee that the bottom of location-plate and connector is respectively horizontal plane after the welding;
4) end with the pedestal embedded part bolt of pre-determined bit adopts respective nut to be fixed on the location-plate, and fastening with track wrench;
5) utilize transit to determine the position of the pedestal embedded part bolt of pre-determined bit, the levelling of recycling level gauge, then will weld in the position of finding accurately of lower floor's reinforcing bar with the positioner of pedestal embedded part bolt, and then guarantee that the bottom of pedestal embedded part bolt is fixed on design attitude;
6) successively colligation middle level reinforcing bar and top reinforcement;
7) the pedestal embedded part bolt is passed the pedestal embedded part that is arranged on above the top reinforcement, utilize line pendant and level gauge to determine the upper end position of pedestal embedded part bolt, and adjust the position of pedestal embedded part;
8) at last pedestal embedded part and pedestal embedded part bolt are fixed with nut.
Compared with prior art, the invention has the beneficial effects as follows: positioning device structure of the present invention is simple, easy for installation, with low cost, and the job site makes easily; Guarantee that the pedestal embedded part shank of bolt can run-off the straight or displacement in the process of fluid concrete, and then make the location of pedestal embedded part more accurate, workmanship is improved.
