2.3.5 roof cover panel before the installation, should be finished wall, ground wet operation projects.
2.3.6 set ceiling construction manipulator frame.
2.3.7 light steel roof in large area before construction, should be done between example, on the ceiling of the bulging, the lamp chamfer, vents and structure processing, by making decision between example block and fixed method, identified recognition after large area construction.
3 operation process
3.1 process:
Play the ceiling elevation to delimit keel along the line, install the horizontal to install the main keel, keel boom
Install a keel installed to cover panel to brush paint, layering
3.2 play ceiling elevation level: according to the floor level is horizontal, vertical to the ceiling design elevation, with your ruler along the wall, and went to play around the ceiling level is horizontal.
Step 3.3 cross keel line: according to the design requirements of the main keel span arrangement, time, in has good ceiling elevation level keel along the line.
Derrick: 3.4 install the keel play ceiling elevation and keel along horizontal line of position, determine the level of end under the boom, according to the main keel position and hanging space, will be no one end of the bolt screw thread with derrick floor embedded bar fixed connection. Not when embedded bar available expansion bolt.
3.5 install the keel:
3.5.1 track of with telescopic boom nut.
3.5.2 install hanging in the main keel accessories.
3.5.3: install the keel will be assembled crane accessories main keel, according to the step line position, the widget through corresponding cup bolt, screw like mother.
3.5.4 main keel thru installed connectors, adjust the elevation, arch of peace.
2.6.2 installation hole additional main keel, according to the atlas of the corresponding node structure, set up the connection card firmware.
3.5.6 nailed keel, using nail fixed. No specific design, nail spacing is 1000 mm.
3.6 installation times keel:
3.6.1 track along the line, according to the good times keel card put times keel accessories.
3.6.2 hang times keel, keel span of time, as stipulated in the design the first keel through condole hang hang on the large keel, design requirements, general spacing is 500 mm to 600 mm.
3.6.3 when times keel length needs to root for long, keel fittings in time, at the same time of hanging times keel, straightening and fixed.
3.6.4 radar echoes captured when using T keel of light steel keel keel card file should be in installing a cover panels, each with a hood panel has installed a level keel.
3.7 installation cover panel: before install cover panel pipeline inspection must be within the ceiling on a variety of acceptance, and after suppression test, are allowed to install the cover panel. Roof cover panel variety, generally in the design document should be clear to choose the type, specification and fixed way. Cover panels and light steel frame fixed way is divided into: cover panel self-tapping screw nail fixation method, cementing cement cover panel method, three kinds of cover panel topkapi fixed method.
3.7 l cover panel self-tapping screw nail fixation method: light steel skeleton has been installed and experienced the following, according to the cover of the specifications of the panel, gap, partition line, from the ceiling in the middle of shun tong long times keel direction to a row cover panel first, as a benchmark, then branches stretches out to the sides installation, fixed cover panel of self-tapping screw spacing is 150 mm to 170 mm.
3.7.2 cover panel cementing cementation method: according to the requirements of design and a variety of cover panels, material selection of cementing material, generally available 401 adhesive, cover panel shall be optional trim, uniform thickness, size, edge stare blankly, neat. Each cover panel bonding should be led the pack, then brush glue in pre-installed keel box bottom, and four surrounding the cover panel of 10 mm to 15 mm wide range brushing glue, after 5 min, to press the cover panel glued to the pre-installed parts; Each roof from middle row first, then to the adhesive on both sides of the branch.
3.7.3 cover panel topkapi fixed method: when the light steel keel is T, more for topkapi fixed method of installation.
T light steel keel installed long time, through inspection level, spacing, straightness and comply with the design requirements of hanging load, perpendicular to the tong long times keel block and keel line card file. Cover panels installed at the end of the line in the middle of the time by ceiling keel, keel, first to a root had class will cover panel slot again into the tee times keel flange or there can be no slot of cover panel is installed in the T on the edge, then install the other side long level keel. Stay adjustable branch installation according to the above procedure, the final branch tee Ming dragon bone.
3.8 installation layering: cover panel ceiling design requirements such as layering, with a roof cover panel installed, adjusted the position, make the seam evenly, to sew the whole hand, according to the layering position line, and then wiring for layering installation. The fixed methods appropriate USES self tapping screw, screw spacing is 300 mm; Cement paste is also available.
3.9 brush anti-rust paint: light steel frame cover panel ceiling, carbon steel and the surface of the welding place treatment done at the end of the (such as embedded parts, accessories, fittings, nailed accessories, etc.), in the process before installation should brush anti-rust paint.
