The wooden keel for the ceiling is made of wood of about the same size.
Light steel keel is made of iron sheet, it includes: main keel, sub keel, hanging bar, big hanging (big hanging), in hanging (hanging), expansion bolts, edge keel, and various specifications of the joint. When installing gypsum board, also need to tap screw (dry wall nails)
Construction technology of gypsum board ceiling in home decoration
In the construction of ceiling of plasterboard condole in the home outfit, every city has adornment association to unite the adornment construction standard that issues. This problem you can go to the association to inquire directly.
Will tell simply, gesso board advocate keel space is in commonly 600~800 between, vice keel space is installed according to modelling inside 600. The hanging bar is 8 mm diameter spiral hanging bar.
Light steel keel gypsum board ceiling construction technology
I. construction conditions
1. First, a main control line shall be released at the construction site according to the provisions in the previous design and construction drawings.
2, ceiling has been according to the keel position of the line
Ii. Construction technology
Construction sequence: the position line of the sling point -- the height line of the sling ceiling -- the perforation installation boom -- the installation of the main keel -- the installation of the t-type main keel and the small bone -- the installation and acceptance of mechanical and electrical equipment -- the installation of gypsum board
1, according to 50 room is horizontal, vertical vector to condole carries on the design elevation, with your ruler office 2.6 m (50 online back to 2.1 m, horizontal allowable deviation plus or minus 3 ㎜), corridor, 2.3 m (50 online back to 1.8 m) along the wall around the ceiling elevation level, and good in the picture on the wall keel along the line, derrick is 150 mm from the wall, both ends of the main keel of wall distance not greater than 150 mm, to 1 m, and every keel spacing below the floor to play good line 1 m * 1 m square. Arch 20mm from the ceiling of the open general office, 5mm from the small office. Arch 2mm from the corridor, arch 2mm from the short span of the room.
2, play ceiling elevation and keel along horizontal line place, to determine the level of the bottom of derrick, according to the big keel spacing, location and boom boom without turnbuckle end with Angle of 40 * 40 * 4 yards welding, derrick with Φ 8 bolts and ceiling.
3. The exposed thread length of the derrick end shall not be less than 3mm. When installing the large keel, connect the large keel with hanging pendant on the derrick and tighten the screws. Large keel length can be connected by connecting plug body. The keel should be leveled after installation.
4, 38 and 50 main keel should be arranged parallel to the direction of lamps and lanterns, derrick should avoid the position of tuyere, lamps and lanterns. Open office ceiling requires 12 meters in the big keel on the top of the horizontal keel welding together, in order to strengthen the lateral stability of the big keel and derrick integrity.
5, the keel installation, elevation, spacing, straightness and hanging load in accordance with the design requirements, after the installation of the roof in the middle row by ceiling keel, starting at the end of the first one had file small keel, and then the calcium silicon on three sides keel flange plate, and then install the other side of the small keel, branch installation according to the above procedure, the last guy to adjust T Ming dragon bone. Smallpox can be installed after water, electricity, air conditioning and other professional processes are completed.
6. The ribs on the back side of the gypsum board shall be cut neatly when the gypsum board meets the lamp mouth, tuyere and wall. Lamps and lanterns, tuyere should adjust well, make board all round in same level line. Non - integral board can be slotted with a plane so that the side of the cutting down to keep it level, the corridor gypsum board must be installed after the nail holes do anti-rust treatment (brush anti-rust paint).
(3) wood keel gypsum board ceiling construction technology
1, wooden keel plasterboard condole in the construction of the top of every square meter with wooden keel about 1.1 meters, because plywood or paper plasterboard is 1.22 meters *2.44 meters of size, generally is the wooden keel into 300*300 grid. Of course it can be decided according to the actual situation.
2, between the two ends of the pull line (cement rope or fish wire), will pull the line tight, you can know whether flat. Plastic water pipe is used to fix the plane waterline, fixed the plane waterline can determine whether the ceiling ends are the same height.
3, in the fixed pull wire must be the time to do a good job of the shelf, after rising, to do a fixed!
4. Wooden wedges.
5, the last is to draw water, 6 mm expansion screws to 5 * 3 wooden keel fixed by the end of the original smallpox (about 1.2 meters) interval, advances the 3 * 2 * 3 (5 (length is slightly lower than smallpox (down), wooden keel frame, hung connect shelf to smallpox was 2 * 3 wood square, adjust the level, highlighted the keel frame will be down (part of the cut, gypsum board. The practice before is the beam that USES whole fir wood house two ends or the wall makes false beam, it is to use 6 li to expand screw now mostly 5*3 wooden square fix to go up to cement smallpox make it small false beam, in order to fix hang down small wooden square.
Arc gypsum board ceiling construction process
Make modelling according to arc with woodworking board first (serve as keel to use), fix plasterboard to go up in woodworking board next. You can't use a light steel keel for this kind of modeling.
