(3) wallboard installation
1. gypsum board installation
(1) Before the gypsum board is installed, local strengthening measures should be taken for the pipes and related auxiliary equipment in the embedded partition wall.
(2) Gypsum board should be laid vertically, and the long side (i.e. enclosure surface) joint should fall on the vertical keel. But when the partition is a firewall,
Gypsum board should be laid vertically; Gypsum board used for curved walls should be laid horizontally.
(3) The gypsum boards on both sides of the keel and the two layers of gypsum boards on one side of the keel shall be staggered, and the joints shall not fall in the same place.
On the keel.
(4) Gypsum board is fixed with self-tapping screws. The screw spacing along the periphery of gypsum board should not be greater than 200mm, and the middle part should be fixed with screws.
The nail IJC distance should not be greater than 300mm, and the distance between the screw and the plate edge should be 0 0-16mm.
(5) When installing gypsum board, it should be fixed from the middle of the board to the four sides of the board. The nail head is slightly embedded in the human board, but the paper shall not be damaged.
noodle Nail holes shall be leveled with gypsum putty.
(6) gypsum board should use the whole board. If docking is needed, it should be close, but it cannot be forced into place.
(7) The joints of plasterboard shall be treated according to the design requirements.
(8) The gypsum board at the end of the partition wall and the surrounding walls or columns shall have a 3 mm notch. During construction, first add it at the notch.
Inject caulking paste, then unfold the plate and squeeze the caulking paste to make it closely contact with the adjacent surface layer.
(9) When the gypsum board partition wall is connected in a T-shape or a cross shape, the internal corners shall be filled with putty and attached with joint tape; exterior angle
Corner protection should be done there.
(l0) When installing the firewall gypsum board, the gypsum board shall not be fixed on the keel along the top and along the ground, and a cross brace keel shall be added separately.
To repair.
2. Plywood and fiberboard installation
(1) When linoleum and oil paper are installed on the surface of plywood substrate to prevent moisture, they should be laid flat, tightly overlapped and without wrinkles.
Folds, cracks and through holes, etc.
(2) If the plywood is fixed with nails, the nail spacing is 80- 150mm, the nail cap is flattened and enters the board surface for 0.5- 1mm, and the nails are nailed.
Smooth your eyes with oily putty.
(3) When the surface of plywood is painted with varnish, the wood grain and color of adjacent panels should be similar.
(4) Fiberboard is fixed with nails, the nail distance is 80- 120mm, the nail length is 20-30mm, and the nail cap should enter the board surface.
0.5 mm, nail hole with oily putty. Hard fiberboard should be soaked in water, dried naturally in the shade and installed.
(5) The wall shall be decorated with plywood and fiberboard, and the corner protector shall be provided at the external corner.
(6) When plywood and fiberboard are fixed with battens, the nail spacing should not be greater than 200 mm, and the nail cap should be flattened.
Layered 0.5- 1mm, nail holes shall be leveled with oily putty.
(4) Equipment and electrical installation
1. Set shelves for closets and attics on the double deck, and install water tanks, radiators, radiator clips, cookers, etc. Which one should I be in?
The keel is added to a fixed position on the board.
2. When setting switches and sockets on both sides of the wall, the holes should be staggered to avoid punching through the wall and affecting fire prevention and sound insulation.
Effect.
3. When installing water pipes inside, heat preservation materials should be wrapped outside the pipes and gas barriers should be made.
4. Partition walls with sound insulation requirements should not be equipped with devices such as through-wall pipes, water tanks, electrical switches, sockets and radiators, if necessary.
Reliable sound insulation measures should be taken during installation.
(5) Surface treatment of plate
1. The flat seam of gypsum wallboard can be leveled with gypsum putty and joint paper tape; When the partition wall length is about 12m, it shall be
Set the control seam (slit the partition wall with metal or plastic battens).
2. Plywood and fiberboard wallboard are generally pressed into layering with wooden strips, metal strips or plastic strips at the gaps.
