Construction Technology of Silicon and Caelite Ceiling in Light Steel
Construction method
?A. Balls: According to the level of the floor level, according to the design of the ceiling ceiling, along the wall around the bottom of the ceiling height of the ceiling, and along the elevation of the ceiling line in the wall with a good keel position line.
?B. Installation of hanging bars: hanging wire selection φ8 hanging bar, one end and L30 * 3 * 40 (long) angle steel plate welding, the other end of the steel head 50mm long thread, and Ф8 expansion bolts fixed to the structure of the ceiling, For the 1200mm-1500mm, against the wall from the wall of the distance of 200-300mm, when encountered a larger ventilation pipe, more than the requirements of the spacing of the boom when the use of angle steel frame keel. Before installing the bucket, you must brush the antirust paint.
?C. Installation of the main keel: the main keel selection UC38 light steel keel, spacing 1200mm ~ 1500mm, the installation of the use of keel matching pendant and hanging connection, pendant with the plug of the wire is fixed, requiring screw cap beyond the screw 10mm. Must pull the main keel pre-adjusted neatly, the same height, check the correct after the next process. D. Installation side keel: the elevation of the wall on the wall around the wall with cement nails fixed 25 * 25 paint keel, fixed spacing of not more than 300mm. Install the side keel before the completion of the wall putty leveling.
Construction process:
?? Bracelet → Striper Slot → Install keel → Install calcium silicate board
Calcium silicate board ceiling is the main advantage of light, waterproof, sound absorption, construction is simple.
1) Material requirements Calcium silicate board specifications, performance indicators meet the design and the corresponding acceptance requirements. The keel, boom and fittings required for the ceiling meet the requirements of the design and catalog specifications.
2) The main construction tools Electric saw, no tooth saw, nail gun, hand saw, hand plane, pliers, screwdriver, wrench, square feet, steel ruler, steel tape and so on.
3) construction conditions and related environment around the wall playing a good roof + 50cm level elevation control line, and verification is completed.
?Install the roof of the various lines and ventilation ducts, to determine the light, ventilation and a variety of exposed Ming mouth position. And check the height of the ceiling and its equipment within the impact of elevation.
?Check whether the materials and fittings used are well prepared. Before the keel, you must complete the wet work on the wall surface. Erected a roof construction platform.
Calcium silicate board keel ceiling in a large area before the construction, should do the model, the ceiling from the crown, lamp trough, vents of the tectonic treatment, block and fixed method should be tested and identified after a large area construction.
