Calcium silicate ceiling 1 Construction technology, elastic line: pop up 50cm control line according to the elevation drawn from the elevation point in advance, and determine the standard line of ceiling design elevation in each room according to the pop-up control line. Draw the step control points of the keel on the wall, and the general distance is about 900- 1200mm.
Construction technology of calcium silicate ceiling II. Installation of suspenders: determine the position of suspenders according to the requirements of construction details, and brush anti-rust paint before installing suspenders. Derrick is made of steel bars with a diameter of Φ 6, painted with antirust paint, and the spacing between lifting points is 900- 1200mm. During installation, the upper end is connected with the iron expansion bolt, and the lower end is connected with the hanger after the conductor is sheathed. The exposed length of the installed boom end shall not be less than 3mm.
Construction technology of calcium silicate slab ceiling 3. Installation of main keel: adopt UC50 or U38 keel, and the distance between main keel of ceiling is less than 1200MM. When installing the main keel, the hanger of the main keel should be connected with the main keel, and the screws should be tightened. According to the design requirements, the springing height is about 1/200 of the short span, and the extension of the main keel should be staggered. Increase the lifting point at the joint, and check the smoothness of the keel at any time. When the ventilation pipe is larger than the maximum spacing requirement of the keel, the keel frame must use angle steel of more than 30*3, and the frame cannot contact with ventilation pipes and other equipment projects.
Construction technology of calcium silicate suspended ceiling 4. Secondary keel installation: according to the different installation methods and specifications of panels, secondary keel can be divided into T-type and C-type, and the spacing of secondary keel is 600 mm. The secondary keel is hung on the large keel through a pendant, and the 600MM cross-brace keel is installed parallel to the main keel with a spacing of 600 mm or 1200 mm. When using the shelving method and tongue-and-groove method for installation, the secondary keel is T-shaped, and the C-shaped keel is selected by pasting method or other fixing methods.
Construction technology of calcium silicate slab ceiling. Installation of side keel: L-shaped side keel is adopted, which is fixed to the wall with plastic expansion pipe or self-tapping screw, with a fixed distance of 200 mm Before installation of side keel, the wall should be leveled with putty, which can avoid pollution and leveling difficulties when the wall is scraped with putty in the future.
Construction technology of calcium silicate suspended ceiling 6. Installation of "T" keel: When installing the keel, add a "T" reinforced keel around the lamps and tuyeres.
Construction technology of calcium silicate suspended ceiling. Concealed inspection: After water and electricity installation, water testing and water pressure are completed, concealed inspection shall be conducted on the keel, and the next working procedure can be carried out only after it is qualified.
Construction technology of calcium silicate slab ceiling 8. Installation of calcium silicate board: the specification and thickness of calcium silicate board are determined according to the design requirements, and the operator must wear white gloves during installation to prevent pollution.
Advantages of Calcium Silicate Ceiling
1, fire performance
Calcium silicate board is a class A incombustible material. If a fire happens carelessly, the board will not burn, let alone produce harmful smell.
2, waterproof performance
Good waterproof performance, installed in the bathroom, kitchen lamps and lanterns with high humidity will not expand, deform, crack and so on.
3, high strength
The strength of calcium silicate board is very high. 6 mm thick board is stronger than 9.5 mm gypsum board, which is very strong and not easy to break.
4, the size is stable
It adopts the most advanced formula and has very strict quality requirements. The plate will not expand or contract because it is wet or too dry.
5. Thermal insulation and sound insulation
The thermal insulation performance is good. The thermal insulation effect of 10mm board is much better than that of wall brick, which is very suitable for owners living in the city center.
6, long service life
Calcium silicate board has good stability, corrosion resistance, acid and alkali resistance and long service life, so it is worth choosing as a ceiling board.
Calcium silicate board is mainly composed of gypsum, while calcium silicate is composed of components such as time, mica and wood fiber. Secondly, the use: calcium silicate board is mainly used for indoor ceilings, and there are also high-grade, middle-grade and low-grade points. The above are the relevant contents of the construction technology of calcium silicate ceiling compiled by Bian Xiao for everyone and the advantages of calcium silicate ceiling. I hope the content of the article can help everyone.
