Bailey piece flower rack

Lay I20 I beam distribution above the beam and longitudinal beret beam. The I-beams are arranged at a spacing of 50cm. The bottom formwork, the inner and outer formwork and the flange plate formwork are supported by steel pipe frames. Top brackets and bottom brackets are added up and down, and square wood and wedge are placed on the top brackets and bottom brackets to adjust the Angle. The bottom of the steel pipe frames in the box girder must be padded with the same strength pad as the beam body to separate the steel pipe from the bottom formwork. The layout density of the vertical vertical rod of the steel pipe support frame is 60cm×60cm between the middle part of the bottom plate, 30cm×60cm under the web position and 90cm×60cm under the flange plate. The perpendicality of the spiral steel pipe column should be less than or equal to 1/200. At the same time, the maximum deviation of verticality should be controlled not more than 50mm; The horizontal deviation of the longitudinal Beret main beam should be no more than 10mm. And the horizontal deviation of the whole frame length is not more than 50mm.
