Office building silicon calcium board ceiling, the actual construction practices: light steel keel spacing 1000mm, small keel spacing 600mm meet the requirements
Light steel keel skeleton after acceptance, began to install the first layer of cement fiberboard. First in accordance with the room space on the cement fiber board layout, layout is not allowed to appear below 100mm slats. After the completion of the version, according to the layout placed cement fiber board, and with self-tapping wire fixed firmly. Self-tapping screw spacing of 150-170mm. After the completion of the first layer of cement fiberboard, should check the flatness of the allowable error should be controlled within 3mm. The first layer of cement fiberboard after the acceptance of the installation has been compressed composite panels, the installation of the use of adhesive method, the installation of the first two sides and then the middle.
Install the main keel
1> equipped with boom pheasant
2> Install the pendant on the main keel
3> Install the main keel: the main keel will be assembled hanging pendant, according to the location of the sub-line to hang the hanging pieces into the corresponding ring bolt.
4> main keel connected with the installation of connectors, pull the line to adjust the elevation, from the arch and straight.
5> around the keel with nailing Hong Ding set. Design no requirements, the nail spacing of 1000mm.
Construction Measures of Caustic Sintered Calcium Silicate Board Ceiling
1, the roof height level: according to the level of the floor level, with the vertical foot to the ceiling design elevation, along the wall to the surrounding height of the ceiling.
2, designated keel file line: according to the design requirements of the primary and secondary keel spacing arrangement, has been on the roof of the standard elevation of the keel sub-line.
3, the installation of the main keel boom, playing a good ceiling elevation and keel sub-file position, to determine the boom under the head of the elevation, according to the main keel location and hanging spacing, the end of the bucket without screw button embedded with the floor expansion Bolt connection is fixed.
