Embodiment Construction
[0020] Such as figure 1 As shown, the cable-rod folding grid structure consists of a plane truss structure 1, a rigid compression bar 2, active cables 3 and passive cables 4. The upper chord nodes of planar truss structure 1 are connected to the corresponding nodes of the upper and lower chords of adjacent planar trusses through rigid compression bars, and the connection mode is hinged; the lower chord nodes of planar truss structure 1 are connected to the upper chord and The node connection at the corresponding position of the lower chord is hinged.
[0021] The planar truss structure 1 can be a double-layer grid or a multi-layer grid.
[0022] The shape of the planar truss structure 1 can be rectangular, fish-bellied, trapezoidal or arched. The planar truss in this example is a double-layer grid, and its shape is a rectangle.
[0023] The planar truss structure 1 has multiple trusses, and the two ends of one truss at the fixed end of the roof are respectively hinged with ...

The invention discloses a cable rod type retractable roof structure. The cable rod type retractable roof structure comprises multiple plane truss structures, upper cord nodes of the plane truss structure are hinged with nodes at positions corresponding to an upper cord and a lower chord of one adjacent plane truss through a rigid compression rod; lower cord nodes of the plane truss structure are also hinged with the nodes at the positions corresponding to the top chord and the lower chord of the adjacent plane truss through the rigid compression rod; the two ends of one plane truss structure at the fixed end of a roof are respectively hinged with a lower support, and the two ends of every other plane truss structure are arranged on a guide rail along the roof retracting direction; and a driving cable and a plurality of driven cables are arranged on the multi-plane truss. According to the cable rod type retractable roof structure, the high-strength stress property of cable material is fully utilized, so that the weight of the structure is reduced, the materials are saved, and the cost is lowered; and due to the characteristic of unidirectional stress of the cable, the cable rod type retractable roof structure is large in contractibility, reasonable in structure and simple in design and construction and can be widely used for large-span retractable roof systems such as convention centers, multifunctional gymnasiums and the like.
Description
technical field [0001] The invention relates to a retractable roof structure used in the construction field, in particular to a cable-bar type retractable roof structure. Background technique [0002] In recent years, the folded grid structure has played an increasingly important role in the fields of architecture, military affairs, aerospace and people's daily life. For many temporary and semi-permanent buildings, folded structures have good economic indicators due to the significant advantages of reusability, and folded structures can be easily transferred as tasks change, and can also be designed into various beautiful shapes. In the field of construction engineering, from the basic requirements of sheltering from wind and rain and resisting infringement, to various performances and parties, the functions of buildings are constantly evolving with the improvement of people's living standards. From the Pantheon in ancient Rome to many modern large-span public buildings wit...
