Further, please continue to refer to Fig. 8, Fig. 8 be the schematic diagram of suspension rod of present pre-ferred embodiments.As shown in the figure, described suspension rod 40 is screw thread suspension rod, the height of three-dimensional adjustable lifting sabot can be regulated by it, to adapt to the needs of different roof structure, also comprise an elastic washer, described screw thread suspension rod 40 can be connected with adjustable mounting seat by nut, and described elastic washer is positioned over below nut, plays anti-loose effect.Described connection pawl 431 is also provided with the bolt hole that can be hinged with the first syndeton of channel above, and its operating principle is the same with bolt hole 432.
Please again consult Fig. 2, described channel 500 comprises the first syndeton, main keel structure and the rider keel structure (not marking in figure) that connect successively further, in embodiments of the present invention, described main keel structure adopts 100C type keel, it is arranged in the first syndeton by securing member (such as bolt etc.), form the frame construction of whole channel, described rider keel structure adopts 40C type keel, adjacent two rider keel structure connectors connect, adjacent two row's interface positions stagger, and the level that is adjusted to after installation is straight.Described rider keel structure is arranged on main keel structure by hanging piece, and fastening with securing member, to prevent the slip of bevel direction.Internals in channel all carries out spray treatment, and color can be determined according to designing requirement.The corresponding fabrication hole of Surface Machining of rider keel structure, does not need welding, also without the need to carrying out secondary antirust treatment.Described panel 500 is arranged on the below of channel, panel can be set according to the space layout of reality, in embodiments of the present invention, described panel is aluminium alloy panel, it is connected on channel: first determine to install axis, install according to corresponding order from axis again, accomplish overall level and smooth, straight, nothing sinking sense.
Further, after panel 500 and channel 400 are installed, panel 500 should be able to bear the static load of designing requirement, and its maximum flexibility deflection must not be greater than 10mm, and amount of plastic deformation must not be greater than 2mm.Its channel 400 and panel 500 can select market-ripe standard series furred ceiling product, avoid specialized designs to make, and save cost.
, when the described ceiling system being applicable to large space curved surface steel structure roofing is in receipts position, limit, need installation one lower chord, its connection space rack and channel with should be noted that.When ceiling system is in receipts position, limit, described lower chord plays fixed ceilings keel.
The construction process of the ceiling system of the large-spatial structures of the embodiment of the present invention is as follows:
1, unwrapping wire location:
By the arrangement requirement of drawing ball node, ball node is numbered one by one.Measure the actual coordinate of each lower edge ball point one by one, and check with theoretical ball node coordinate, according to the actual height of furred ceiling finished surface, calculate the length of suspension rod, the usage quantity of changeover panel and triangular support bracket and position; Recycling total powerstation, according to rack present situation, first a fixed reference line on frame ball node, then makes the position of suspension rod by reference line, and furred ceiling finished surface distance rack lower edge ball's dead center distance is 750mm.Measuring process can adopt the modes such as bracing wire to adjust fixed point.The base position that each unit is made marks by red pigment on rack.
2, lower edge ball node installs adjustable mounting seat:
According to field measurement, lower edge ball node locates adjustable mounting seat.For receipts position, limit, as pillar, outer curtain wall place, then adopt special adjustable mounting seat on request, be arranged on lower chord.The required accurate positioning of adjustable mounting seat, installation are firmly.
3, hanger erection and upper limit nut install (in the present embodiment, described suspension rod is screw rod):
Be that the bolt hanging axis of 20mm inserts in the screw hole of adjustable mounting seat by diameter, then make upper limit nut location according to unwrapping wire, then upper limit nut is contained on bolt hanging axis.
4, three-dimensional adjustable lifting sabot is installed:
Three-dimensional adjustable lifting sabot is loaded bolt hanging axis, and lower position nut of screwing on, is namely fixed on main roofing Elements of Space Grid Truss by bolt hanging axis.
5,100 C type main joists are installed:
C type main joist is arranged on and is rotationally connected on pawl, and use bolton.Level is adjusted to straight after installation.
6,40 C type rider keels are installed:
The special hanging piece of C type rider keel is mounted on main joist, and uses bolton.Adjacent two keel connectors connect, and adjacent two row's keel interface positions stagger, and the level that is adjusted to after installation is straight.
7, installation panel suspension member:
Arrangement distance installation panel suspension member by drawing, uses M6X20 bolton.
8, perforated aluminum alloy panel is installed:
Determine that smallpox installs axis, and install according to corresponding order from axis, ethylene-propylene-diene monomer film is socketed on the flanging of plate face.And be stuck in the draw-in groove of panel suspension member.At holding screw.Different units needs the gap adjusting plate face, accomplishes level and smooth, straight.
Further, when mounting fastener, main keel structure, rider keel structure and panel, also the securing member of other models, main keel structure, rider keel structure and panel can be adopted, and to be not limited in the present invention be model in embodiment, as long as installation requirement can be met, realize the features such as whole system welding, good endurance.
Generally speaking, as shown in Figure 1, it comprises the method flow of the described ceiling system for engineering steel work:
S1, unwrapping wire is located;
S2, rack lower edge ball node installs adjustable mounting seat;
S3, installs suspension rod;
S4, installs three-dimensional adjustable lifting sabot;
