The construction of suspended ceiling includes four steps:
1. Prepare the materials for the suspended ceiling, measure and mark the ceiling ceiling; 2. Install wooden keel and light steel keel; 3, make a wooden ceiling modeling; 4. Ceiling sealing plate.
1. Read the drawings and fully understand the drawing modeling
2, plane the wood, brush on fire retardant paint
3, on the wall to pop out of the ceiling horizontal line, and according to the need, on the top of the first to fix a few longitudinal keel
4, the production of keel frame, can be nailed on the ground first, the special-shaped top of the application of joinery board to make a model
5, use the derrick to fix the wooden keel, and pay attention to adjust the horizontal and vertical
6. Reserve the bottom plate of the lamp holder or the position of the lamp slot
7, by the electrician will connect the wire, and put aside the wire head
8. Fix the cut gypsum board with self-tapping nails
1) use the horizontal tube to find the horizontal point, and use the ink bucket to bounce the horizontal line along the horizontal point;
2), light steel keel: wooden keel as dragon, lamp chamfer position made of wooden keel or carpentry board, there are wooden as must brush fire retardant coating, keel at least 50, 30 centimeters advisable, spacing between 60-80 centimeters advisable, hanging spacing between gypsum board and board to artificial reserved 5-8 mm gap, plasterboard 1-2 mm tapping screw retraction and do the embroidery processing, to achieve smooth and firm, to achieve the smooth lines.
3), wooden keel, keel at least above 3 * 4, spacing between 30 centimeters advisable, 60-80 centimeters advisable, hanging spacing steel hanger forbidden directly using the wedge shape of studs on the top, brush fire retardant coating closely until see color wooden keel, keel on cast a layer of full scale on plasterboard again after nine mile willow eucalyptus core board, gypsum board and the board to artificial reserved 5-8 mm space between, plasterboard 1-2 mm tapping screw retraction and do the embroidery processing, to achieve smooth and firm, to achieve the smooth lines.
4), aluminum gusset plate: strict requirements of the level, light steel keel teeth to align, keel spacing within 50, hanging bar spacing 60-80 cm is appropriate, the hand to be light when the board, so as not to press the board surface out of the pit, the edge and ceramic tile contact is not strict to use sealant.
5), aluminous model board: wooden keel at least above 3 * 4, spacing between 30 centimeters advisable, hanging spacing 60-80 centimeters advisable, brush fire retardant coating closely, covered a layer of full scale on keel willow eucalyptus core adhesive paste of the reoccupy after nine mile board aluminous model board, aluminous model board with board between to reserve 3-4 mm gap, has played a frame for fill other colour effect, to achieve smooth and firm, alien to do line is fluent, fold the sleek Angle to be broken.
Process flow of aluminum gusset ceiling
1, according to the ceiling of the pipe, determine the height of the ceiling, and according to the height of the horizontal line.
2. Make holes to fix the edge and corner bar of the aluminum gusset along the horizontal line, and the corner bar shall be diagonal at the Angle of 45 degrees at the corner.
3, determine the position of the main keel, holes in the ceiling, the installation of hanging bar.
4, the use of hanging bar will be the main keel fixed.
5, the aluminum gusset plate in turn on the main keel (strip aluminum gusset plate shall be cut into a suitable length)
6. Level the aluminum gusset plate.
Acceptance process of wooden keel ceiling
Concrete base without ceiling
1. Construction shall be carried out according to the operation order.
2, the basic level is clean, and the ground ash combined firmly, no empty drum.
3, the surface is flat and smooth, can not see the trace of the iron float, no foaming, peeling, cracks.
4, if the surface brush emulsioni paint, the quality requirements can refer to the wall cylinder emulsion coating quality inspection requirements for inspection.
Wooden ceiling
1. Construction shall be conducted in the order of operation.
2, the wooden keel without the knot scar, the wooden keel is connected firmly, the derrick and the wooden keel, the floor plate is connected firmly.
3, keel are to be painted with fire resistant paint.
4, ceiling keel to consider future sag, so after installation, the center should be short side arch 1/200.
5, where there are lampshades, curtain boxes and other positions should be increased keel, ceiling fans can not bear in the keel frame.
6, cover panel should be flat, no warping Angle, peeling, degumming phenomenon, such as Mosaic, pattern should be designed according to the requirements of the regulations.
Lath, wire mesh plaster ceiling
1, wooden keel frame requirements with wooden ceiling.
2, the strip joint must be staggered, the surface should not be over light, the strip and wire mesh are nailed.
3, stone plaster must be fully mature, do not allow lime fixed particles, so as not to puff up bubbles after plastering.
4, the strip is dry, easy to expand water absorption, water absorption after the plastering dry easy to crack, so the bottom of the ash should be dry water wetting, then wipe the leveling layer can be combined with each other.
Light steel keel ceiling
1, the selection of light steel keel should meet the design requirements, to ensure quality.
2. All parts and keels in the ceiling shall be galvanized.
3, keel, derrick, connecting parts should be in the correct position, the material level off, straight, firmly connected, no loose.
4, where there are suspended load bearing parts must be increased transverse keel.
5. The derrick shall not exceed 300mm from the end of the main keel.
6, quality allowed deviation standard can refer to the wooden ceiling.
Of aluminium alloy keel condole top decorate quality how to check, also can consult light steel keel condole top.
