Further, the arched horizontal plane is rectangular. I.e. its ground projection is rectangular in shape. The horizontal projection of the transverse cables is parallel to the wide line of the rectangle and perpendicular to the long line of the rectangle, so the transverse cables are called as the transverse cables. The transverse cables are at least two, so the transverse cables are also called transverse reinforced double cables.
Furthermore, the transverse cables are uniformly distributed in the arch shape.
Furthermore, the cross reinforcing cables have the same structure.
The cross reinforcing cable is formed by crossing two large-diameter steel cables and is in an X shape. When the "X" shape is rotated by a certain angle, the "X" shape can be regarded as a rough "cross" shape, so the "X" shape is called as a cross reinforcing cable. The diameter of the large diameter steel cord is greater than 33.0 mm.
The utility model discloses in, horizontal cable plays the effect of cross section restraint unit, and the cross is strengthened the cable and is played the effect of alternately restraint unit. They act together to constrain local horizontal deformation of the main body of the air-bearing membrane inside the rope.
Furthermore, the cross reinforcing cables are respectively connected with the cross single cable net.
Horizontal cable, cross reinforcing cable and alternately single cable net combine to constitute the utility model discloses a reinforcing cable net system, it is connected with alternately single cable net as main horizontal atress component, further retrains the local horizontal deformation of the inside gas of cable bearing membrane main part.
Furthermore, the included angle between the cross reinforcing cable and the long side line of the air bearing membrane main body is 44-46 degrees. The degree is an angle.
The utility model has the advantages that:
1) The utility model discloses a strengthening cable net system can strengthen the whole horizontal rigidity of air-supported membrane main part, undertakes more horizontal wind load, and the at utmost reduces the wind load to the effect of alternately single cable net, reduces alternately single cable net's atress.
2) The transverse reinforcing double cables in the reinforcing cable net system have obvious control effect on the horizontal displacement of the air bearing film main body;
3) The stress reduction effect of the crossed single-cable net between the crossed reinforcing cables in the reinforcing cable net system and restrained by the crossed reinforcing cables is obvious, and the stress of the crossed single-cable net can be homogenized.
4) Can be used in typhoon areas, and the application range is enlarged.
5) The utility model discloses a cable system is strengthened to air supporting membrane major structure cross has that the form is novel, pass power simply clearly and definitely, and the atress is reasonable, does not influence whole building outward appearance, is convenient for make and install, has stronger actual meaning.
