A kind of double-layer two-way
layout high formwork construction method of Bailey frame, comprises the following steps: (1) the construction of lattice type steel
pipe column, comprises the construction of independent foundation under steel
pipe column, the arrangement of oblique support between steel
pipe column, lattice structure Erection of the I-steel cover beam on the top of the lattice-type steel pipe column; (2) Lay the main Bailey frame on the upper part of the I-steel cover beam of the lattice-type steel pipe column, parallel to the direction of the main beam, and used for the lower support of the main beam during concrete pouring ;(3) Lay the secondary Bailey frame on the upper part of the main Bailey frame, parallel to the direction of the secondary beam, for the lower support of the secondary beam concrete pouring; (4) Lay the I-beam distribution beam on the upper part of the main and secondary Bailey frame , evenly transfer the upper load to the lower Bailey frame; (5) Set up a
scaffold above the I-beam distribution beam for the formwork of the primary and secondary beams. The present invention adopts a high-support formwork
system combined with lattice-type steel pipe columns and Bailey beams arranged vertically and horizontally, which has good strength, rigidity and stability, high erection height and large span, effectively solving the
bearing capacity and The problem of insufficient stability and limited erection height is suitable for concrete pouring of beams with high height from the ground, large cross-section and large span, and vertical and horizontal arrangements.
