With the railway station awning is example, and it is as follows to adopt ceiling connecting structure of the present utility model to carry out the step of furred ceiling construction:
1, measurement and positioning unwrapping wire
According to furred ceiling design construction measurement scheme, according to the actual conditions at scene, each platform is established the major control line of 2 road parallel longitudinal lines (being parallel to line direction) as east-west direction, guarantees vertical straightness accuracy.According to former I road parallel lines, emit two control points of every axis on the ground, utilize total powerstation to project on the main couple, and make a mark with the red symbol pen, stride whenever then and hang up logical line.
Utilize and emit vertical control point on the ground, utilize the total powerstation horizontal direction to revolve and turn 90 degrees, project on the purlin, at the 1-2 of each platform axle, the 25-26 axle is respectively put horizontal (horizontal path) line, and makes a mark with the red symbol pen, as the foundation of the horizontal control of furred ceiling.With transit or total powerstation the coordinate control point is led on furred ceiling face structure or the keel.Laterally line, vertical hanging wire is determined control sideline, inclination angle and the absolute altitude of each bar (piece) ceiling board and keel.
The furred ceiling absolute altitude draws instruments such as establishing available non-prism total powerstation, laser range finder, level gauge.
2, primary and secondary skeletal frame is installed and is proofreaied and correct
Main joist is 40 * 4 galvanizing angle steel, the first long locating hole of 50mm is driven on one side of angle steel, the hole center distance is 150mm, and main joist requires to be welded in steel work purlin bottom flange epithelium, and spacing is 1 meter, length is according to the actual measurement of on-the-spot purlin spacing, with the effective lap length of i iron purlin greater than 80mm, the fillet weld both sides are elongated, face of weld adopts preservative treatment, angle steel is necessary for whole section, must not dock, overlap.U type keel add that two flanks constitute special windproof keel, and thickness is 1.0mm, the preservative treatment of surface black baking vanish, suspension rod is a M8 galvanizing screw rod, and the link of suspension rod and U type keel is fixed, the elongated mantle fiber of screw rod, the suspension rod theoretical length is 130-160mm, and the suspension rod spacing is 800mm.U type keel and suspension rod march into the arena and qualified by inspection after, assemble on ground, the end that suspension rod is fixing penetrates in second locating hole of holding successfully on the U type keel, the other end is tightened with nut, refills two nuts then, is used to lift being connected of back and main joist.After U type keel and suspension rod assembling are finished,, must there be two personal two ropes to winch to the top simultaneously from ground during lifting by manually lifting to awning from ground, the rope of lifting usefulness must be solid reliable, makes regular check on, and finds to have fracture of wire, phenomenons such as wearing and tearing are changed immediately.U type keel are installed after winching to the awning top, suspension rod are penetrated in first locating hole of accomplishing fluently on the main joist, adjust the keel height according to the absolute altitude line that truss two ends band is good, then double nut about screw rod and the main joist employing is fixedly tightened,
3, ceiling board vertical transport
Utilize rope that furred ceiling system is hung firmly forward to draw and hang work plane (keel below)
4, ceiling board fixed installation
Metal batten (on-gauge plate) amplifier that will have bound edge is to the correspondence position below, use nylon rope to winch on the awning, bound edge with metal batten is anchored in the installing hole of U type keel correspondence again, the bound edge and the corresponding metal batten mouth fixture block of metal batten are fixed, then the windproof fixture block of corresponding elasticity is depressed.
5, the metal batten adjustment is proofreaied and correct
Adjust correction with regulating the absolute altitude of bolt with metal batten, inclination angle, axis, skew, plate seam, planeness etc., make it to reach designing requirement.The principle of adjusting is: vertical hanging wire, and laterally horizontal sliding guarantees that the position of every block of plate and absolute altitude are accurate, and big face vertically becomes line, and plate stitches evenly, the requirement of planeness compliant.
Suspended ceiling connecting system described in the utility model is successful Application on multinomial actual engineering, has obtained significantly through benefit, and the utility model is enumerated following case history:
Case history one:
Station, Taiyuan 1-4 platform does not have post awning engineering in construction on December 25,26 days to 2008 November in 2008, the wherein about 32000m of platform shed furred ceiling area
2All platforms all are the operation passenger platform, electric locomotive traction, and the 27500W contact net is all charged, furred ceiling maximum height 13.8m, workload is big, operation danger, and the duration is tight, construction period is on the occasion of closing on spring transportation, train arrival ﹠ leaving density is big, and the volume of the flow of passengers is multiplied, and passenger's traffic can not be affected in the construction; Furred ceiling duration of a project pressure is huge, also must parallel flowing water construction with the platform construction organization that is carrying out simultaneously on preceding working procedure steel roof truss, purlin operation and part ground.If adopt traditional furred ceiling mode to construct, only turnover expects to pile with platform, and not only the tissue difficulty of shelf work post, turnover material gives passenger transportation management's influence at station very big.
Adopt shaped metal batten ceiling system described in the utility model and corresponding construction method of installation thereof to construct, and succeed.Realized the speed at the thousands of square meters of construction section day furred ceiling, 5 day time, 32000m are only used in the continuous construction of a platform furred ceiling operation
2Furred ceiling was all finished in 29 days, guaranteed finishing of total duration, acceptance of engineering quality is all qualified, and a routine security incident does not take place, and save more than 130 ten thousand yuan of cost direct costs, for having guaranteed that the station, Taiyuan normally runs the indirect value and the social benefit of generation and have more importantly meaning.
Case history two:
Station, Jiujiang reconstruction and extension project of Hot work in progress at present is that station, Jiujiang does not have platform post awning and is about 500 meters, and width is about (single platform) 17 meters, and the ceiling board construction area is about 60000 square meters, and furred ceiling adopts the inferior white aluminium alloy plate of 180/120 bar shaped, thickness of slab 1.0MM.Aluminium-plastic panel closing in construction area is about 6000 square meters, and material adopts the thick white aluminum veneer of 2.5MM.The absolute altitude of awning peak is about 19 meters, and the absolute altitude of minimum point is about 15 meters.Because job site complicated condition, abominable, the position of formal engineering is born the interim processing district of several units of taking part in building of underground construction substantially, the construction passage is occupied, can not rise shared place basically.
In order to change the passive situation of this no operatton face, guarantee that the node duration finishes on schedule, project management department has carried out detailed investigation to the influence factor at scene, and in conjunction with the construction experience of relevant works, adopt shaped metal batten ceiling system described in the utility model and corresponding construction method of installation thereof to construct, utilize a tangent space to carry out construction organization with all strength.Quality safety is controlled in order, has reached the duration target of expection, and has saved more than 240 ten thousand yuan of cost direct costs, has obtained obvious social and economic benefit.
