A keel is needed to install the ceiling. The following briefly introduces the construction technology of wooden keel ceiling:
Construction technology of wooden keel ceiling: 1, lofting
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). Can be measured by level or water column method.
Step 2: Determine the modeling line: according to the design requirements, draw the modeling line with * * * on the top surface or culture surface.
Construction technology of wooden keel ceiling: 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 bolt, embedded parts, etc. Usually used to install lifting points and lifting rods. The lifting rod can be steel bar, angle steel or square wood, and the lifting point and lifting rod can be connected by welding, binding, hook, bolt or screw.
Construction technology of wooden keel ceiling: 4. Fix the keel along the wall.
Drill a hole above the elevation line with an impact drill, mark the hole with a wooden wedge, and nail the keel on the wooden wedge along the wall.
Construction technology of wooden keel ceiling: 5. Hoist and fix the keel.
Hang the assembled wooden keel directly above the elevation line with iron wire, temporarily fix it, and pull out several parallel lines and oblique lines along the ceiling elevation line with rod rope or nylon line. Based on this, slowly move the keel to be flush with the elevation line, and then connect it with the derrick. Similarly, the keel of the cascade ceiling is fixed, and the upper and lower keel are connected.
Construction technology of wooden keel ceiling: 6. Leveling and arching of keel.
After the whole keel is connected, pull out the diagonal crosshair below the bottom of the ceiling, check and adjust the flatness of the ceiling, and arch camber can be achieved when the area is large, and the arch camber height is about 1/200~ 1/3000 of the room span.
Construction technology of wooden keel ceiling: 7. Install paper reinforced gypsum board.
Nail the paper reinforced asbestos board to the keel with self-tapping screws. During installation, it should be noted that the long side of gypsum board must cross the secondary keel vertically, so that the end edge falls in the center of the secondary keel.
Gypsum board should be installed in a free state and fixed from the center of the board to the periphery in turn, leaving a gap of 6mm between gypsum board and culture surface.
The distance between the screw and the plate edge is 10- 15mm, and the nail spacing of self-tapping screws is not more than 200mm (optional 150- 170mm).
After the plate nailing is completed, plastering putty is used to fill the plate joints and nail holes, and seam paper tape or glass fiber mesh tape is used to repair the dry plate joints of solid materials. All caulking shall be carried out after the previous caulking putty is dried.
Through the above introduction, we know the construction technology of wooden keel ceiling, so it is easier to solve the construction problem of light steel keel ceiling. The above is our summary and arrangement, and we sincerely hope to provide you with more and more useful information when decorating together.
