Construction method of woodworking keel ceiling What are the precautions for the installation of woodworking keel ceiling?

When we decorate, there are many places to pay attention to when choosing materials. You can pay attention to the ceiling of woodworking keel, because it is relatively convenient to install and beautiful. Then do you know the construction method of woodworking keel ceiling? What are the precautions for the installation of woodworking keel ceiling? The following small series will continue to give you a comprehensive analysis.

A, carpentry keel ceiling construction method

1, pay-off

Steps: Determine the elevation line, take the floor reference line as the starting point, measure the height of the ceiling (plus the thickness of a plate) 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.

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 can be connected with the lifting rod by welding, binding, hooks, bolts or screws.

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.

5, keel lifting fixed

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.

6, keel leveling, bulging

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.

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 be perpendicular to the secondary keel, 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.

Second, what are the precautions for the installation of woodworking keel ceiling?

1, during installation and construction, attention should be paid to the protection of all kinds of pipes installed in the ceiling, and the wooden derrick and keel are not allowed to be fixed on ventilation pipes and other equipment. Wood skeleton materials, especially decorative plates, should be properly managed in the process of entry, storage and use, so that they are not deformed, damaged by moisture and polluted.

2. Pay attention to all exposed iron pieces on the ceiling. Anti-corrosion paint must be painted before nailing the panel, and the contact surface between the wooden frame and the structure should be treated with anti-corrosion treatment.

3. Pay attention to the varieties of ceiling panels installed at the bottom of the wooden frame, and their varieties, specifications and fixed construction should be carried out according to the design requirements. The cover plate and the wooden frame are fixed with wooden screws.

The above is the construction method of woodworking keel ceiling shared by Bian Xiao.
