Embodiment Construction
[0037] Examples see figure 1 , figure 2 As shown, this large-area lower edge embracing type high-perforation aluminum plate curved surface ceiling includes suspenders, light steel keel systems and metal ceiling panels under the steel structure beams, and is characterized in that: the steel structure beam 2 is a work The lower flange of the steel structure beam hangs and connects U-shaped clips.
[0038] The U-shaped clip includes a pair of main hanging angle steels 13 and a transverse angle steel 14 connected between the two main hanging angle steels 13, and the above transverse angle steels 14 are connected with the angle steel suspenders 3 in a T shape.
[0039] The two main hanging angle steels 13 of the U-shaped fastener are hugged and connected to the upper surface of the lower flange of the steel structure beam 2, and at least two round holes are opened on the horizontal flange of the transverse angle steel 14, and a welding nut 26 is welded under each round hole, The...

The invention provides a large-area lower edge nested aluminum plate curved hung ceiling with high punching rate and a construction method thereof. The bottom flange of an I-shaped steel beam is suspended and connected with a U-shaped fastener. The U-shaped fastener comprises a pair of main suspending angle steel and a piece of transverse angle steel connected between the two pieces of main suspending angle steel. The transverse angle steel is connected with an angle steel suspender in a T shape. The two pieces of main suspending angle steel of the U-shaped fastener are nested and connected to the upper surface of the bottom flange of the steel beam. The horizontal flange of the transverse angle steel thereon is provided with two circular holes. The lower end of each circular hole is welded with a nut. The upper end of a jackscrew passes through the nut and the circular holes and is pressed on the lower surface of the bottom flange of the steel beam. The lower end of the angle steel suspender is connected with a conversion layer steel frame, and the conversion layer steel frame is connected with a primary steel keel and a secondary steel keel in the shape of meshes and connected with a lightweight steel suspender, the lower end of the lightweight steel suspender is connected with a lightweight steel keel system by a hanger and a connecting bolt. The lightweight steel keel system is fixedly connected with a metal ceiling plate. The invention solves the technical problem of ceiling ultra-large space curved steel structure roof.
Description
technical field [0001] The invention relates to a suspended ceiling structure on a steel structure roof and a construction method thereof. Background technique [0002] In large-scale public buildings, the large-space steel structure roof has the characteristics of large structural span, construction errors in the positions between structures, complex spatial structure, and difficulties in the measurement of ceiling decoration engineering and the positioning of lifting points. There are technical problems of high construction cost and slow installation speed in the construction of suspended ceilings with super large space surfaces. The known suspended ceiling structure is a light steel keel system, the light steel main keel and the light steel secondary keel are connected by fasteners, and the suspension rod is directly connected with the steel structure. Its operability is poor, the process connection is not tight enough, the work efficiency is low, the overall speed and a...
