1, when used in the ceiling, the long side of gypsum board must be vertical with the subkeel or laid in each city, fixed parts (from tapping screw) with the distance of gypsum board about 10-16mm, when fastening, gypsum board must be fixed with the skeleton;

2. When fixing the board, fix the board with the long and short sides in the middle of the board.

3, plasterboard butt should be tight, the seam must add horizontal keel, plasterboard should be installed in a state of no stress, not forced pressure positioning, should ensure that the bottom of the vice keel in the same plane, keel extension long insertion position should stagger.

Installation method

Play line

Use level in the room (column) Angle on each wall take out point (if the wall is longer, the middle is also appropriate to copy a few points), pop-up level (level line according to the ground is usually 500 mm), from the standard line to condole carries on the design height plus 12 mm (the thickness of a layer of white bone plate), with a chalk line (column) along the wall popup level line, for suspended ceiling keel namely skin under line. At the same time, according to the ceiling plan, in the concrete roof pop-up main keel position. The main keel shall be divided from the center of the ceiling to both sides, with the maximum spacing of 1000mm, and mark the fixed points of the boom, with the spacing of the boom fixed points of 900mm ~ 1000mm. If the fixed point of the beam and pipe is larger than the design and procedure requirements, the fixed point of the boom should be added.

Fix the hanging rod

Use expansion bolts to fix the hanging rod. Not the top of the ceiling, the length of the boom is less than 1000mm, can be used with a boom of 6, if the big 1000mm, should be used with a boom of 8, also should set reverse support. The suspender may be cold-drawn and round bars, but round bars shall be mechanically straightened. The ceiling of the people, the length of the boom is less than 1000mm, can be used with 8 boom, if larger than 1000mm, should be used with 10 boom, also should set reverse support. One end of the boom should be welded with the L30×30×3 Angle code (the aperture of the Angle code should be determined according to the diameter of the boom and expansion bolt), and the other end can be used to tap out the screw rod larger than lOOmm, or the finished screw rod can be purchased for welding. The finished suspender should be rust-proof. The suspender should be fixed on the floor with expansion bolts and punched with electric hammer

Hang the rod on the beam

(1) the hanging rod shall be straight and have sufficient bearing capacity. When the embedded bars need to be extended, they must be welded firmly and fully.

(2) the distance between the boom and the end of the main keel shall not exceed 300mm, otherwise, the boom shall be added

(3) additional suspender shall be provided for ceiling lamps, tuyere and access port.

V - type hanging keel installation
1, when used in the ceiling, the long side of gypsum board must be vertical with the subkeel or laid in each city, fixed parts (from tapping screw) with the distance of gypsum board about 10-16mm, when fastening, gypsum board must be fixed with the skeleton;
2. When fixing the board, fix the board with the long and short sides in the middle of the board.

The thin wall profile with reasonable "T" section structure is made by cold rolling continuous hot dip galvanized steel strip and paint strip.

Side keel


The installation of side keel should be in accordance with the design requirements of spring line, along the wall (column) of the horizontal keel line l-shaped galvanized light steel rod with self-tapping screw fixed on the embedded wood brick; If be concrete wall (column), usable shoot nail is fixed, shoot nail space should not exceed the space of condole top second keel.


   Erection of main keel
(1) the main keel should be hung on the boom. Main keel spacing 900 ~ 1000mm. Main keel is divided into light steel keel and t-shaped keel. Light steel keel can choose UC50 medium keel and UC38 small keel. Main keel should parallel room long to install, at the same time should arch, arch height of the room span 1/200 ~ 1/300. The cantilever section of the main keel should not be greater than 300mm, or the boom should be added. The extension of the main keel should take docking, adjacent keel joint to stagger each other. Advocate keel hangs after should be basic adjust level.
(2) span is bigger than the condole top of 15m above, should be on advocate keel, every lie between 15m adds a big keel, and perpendicular advocate keel is welded firm.
(3) if there is a large modeling ceiling, the modeling part should be welded into a frame with Angle steel or flat steel, and should be firmly connected with the floor.

Erection of secondary keel

Sub - keel keelson and dark keel two. Ceiling of condole of dark keel: when installing cover face plate namely second keel is enclosed in shed, cannot see in ceiling surface second keel. Ming long bone condole supports: when installing cover face plate namely second keel is exposed in cover face plate next, can see in ceiling surface second keel. The secondary keel should be mounted against the main keel. Subkeel spacing 300 ~ 600mm. Second keel cent is keel of keel of paint of T form bake, aluminium alloy keel of T shape, and all sorts of strip gusset plate manufacturer matchs the special keel that take. Join piece of iron of T form galvanize when fixing second keel on advocate keel, the two ends of second keel should be put on the horizontal flange of L form side keel, strip gusset plate has the line of shade Angle of special side keel to do.
