What is the construction procedure of wooden ceiling?
1, pay off? Step 1: Determine the elevation line, take the floor datum line as the starting point, measure the height of the ceiling (plus the thickness of a layer of board) on the cultural (column) surface according to the design requirements, and draw a marking line at this point (as the lower leather line of the ceiling keel). Available level or water column method. ? The second part: Determine the positioning line of modeling: according to the design requirements, draw the specific positioning line of modeling on the top surface or cultural surface.

2. Wooden keel assembly? Before hoisting, the wooden keel shall be assembled on the floor (ground), and the assembly area shall generally not exceed 10 floor. The method of keel assembly often adopts the method of bite and semi-Zen buckle assembly. Its specific practice: keel grooving, biting groove, glue groove, and fixing with nails. ? Construction technology of wooden keel ceiling.

3. Install lifting points? Expansion bolts are often used to install lifting points and lifting points of lifting rods.

Or: 1. Determine the elevation line; 2. Determine the modeling position line; 3. Determine the location of the lifting points: suspended ceiling suspended ceiling, the lifting points are generally per square meter 1 piece, evenly distributed on the suspended ceiling. For the ceiling with cascade shape, attention should be paid to the arrangement of lifting points at the junction between floors, with the spacing of lifting points being 0.8 ~ 1.2m, and lifting points should be arranged separately for larger lamps. Then, the wooden keel was screened and treated with fire prevention. Generally, the wood surface is painted with fireproof paint, or the wood can be immersed in a fireproof paint tank.
