Measurement positioning:

First of all, technicians are familiar with the drawings, technical measurements, but there are full-time measurement workers according to the technical requirements of the control network from the control of embedded parts and bolts of the control line and elevation control line. Design of embedded anchor bolts and embedded parts center, set specific position according to the elevation.

The fixed support should be set up first

The relative elevation points are put on the fixed support vertical pile, and the bottom should be welded reliably, completely separated from the formwork fixing frame and the steel bar fixing frame, and the rigidity and stability of the fixed frame should be ensured.

Placing bolts and temporary fixing

When the fixed frame is set up, the bolt should be fixed according to the positioning line, then the elevation is adjusted, and the temporary reinforcement is carried out according to the requirements of the scheme.

Retest and final fixation

Bolts and pre embedding by measuring work again on the bolt and embedded parts adjust and check, after checking meets the requirement, then the lower part and the fixing frame welded and fixed bolt. At the same time, the bolt holder is welded vertically and horizontally in two directions to strengthen the shear brace.
