Lay and install the floor deck support plate and floor deck. After positioning, floor deck should be fixed to the structural members by welding immediately. Any unfixed floor deck may be blown up or slipped by the wind and cause an accident. Where the steel bearing plate overlaps with the steel beam laterally, or between the steel bearing plate and the steel bearing plate, they must be fixed across the span or at a distance of 90 cm (whichever is the smaller value). Clip). Laying and installation of steel bearing slabs and floor deck, the clamped connection between the floor decks and the floor deck, the riveting points are even and effective, so that the laying surface forms a stable whole, or the upper flange of the beam and the floor decks Laying inconsistent elevations, pad steel plates on the upper side of the beam (spot welding and beam welding are firm) to support the floor deck.

Laying and installation of floor deck bearing plates and floor deck:

1. The bending deformation should be corrected before laying.

2. The top surface of the steel beam should be kept clean to prevent moisture and dry paint.

3. Before installing the floor deck, the line where the floor deck line is laid should be marked on the beam. When laying floor decks, the corrugated notches of the ends of adjacent two rows of floor decks should be aligned. After the board is hoisted in place, start with the steel beam that has been ejected from the starting line, and place the single block in the direction of the laying. After reaching the control line, the board seam should be adjusted appropriately.

4. The board should be loosened and adjusted in strict accordance with the requirements of the drawings and specifications. The straightness of the board is a large deviation of 10mm in a single span, the staggered requirements of the board are less than 5mm, and it can be connected to the main beam after passing the inspection.

5. Laying direction of floor deck: Two adjacent plates should be overlapped along the wind direction with larger frequency.

6. Laying of irregular panels: According to the layout of the steel beams on the site, the center line of the steel beams is used to pay off, and then the control line is released to obtain the actual area of the floor deck, and then the width of the floor deck Typesetting. After that, the floor deck is staked out, cut, and the floor deck is pre-assembled on the ground on the platform. It is found that there are parts that are not tight and not tight enough to be adjusted. Lay it according to the actual layout and connect it firmly.
