Embodiment Construction

[0017] The present invention will be described in detail below by means of the accompanying drawings.

[0018] Such as figure 1 , 2 , shown in 3, a combined structure formed by a statically indeterminate ring truss structure and a cable dome structure, including a peripheral statically indeterminate ring truss structure and a cable dome structure, and the cable dome structure and the peripheral statically indefinite ring truss are connected by hinges Way.

[0019] The combined structure formed by the statically indeterminate ring truss structure and the cable dome structure can effectively solve the problem that ordinary long-span buildings need multiple internal load-bearing columns, and achieve the effect of releasing space.

[0020] The peripheral ultra-static ring truss structure includes load-bearing piers 1, load-bearing columns 2, struts 3 and truss rods 4; And pressure bar 9.

[0021] The peripheral statically indeterminate ring truss structure is consolidated with...

Abstract

The invention provides a combination structure of a statically-indeterminate ring truss structure and a cable dome structure. The combination structure comprises a peripheral statically-indeterminatering truss structure and the cable dome structure. Outer ends of upper chord ridge cables and lower chord oblique cables are connected with ring trusses through cable connection lug boards. The peripheral statically-indeterminate ring truss structure is fixedly connected with the ground. A self-stress space structure system is formed by the cable dome structure and press rods through the upper chord ridge cables and the lower chord oblique cables. Outer ends of the peripheral upper chord ridge cables and the peripheral lower chord oblique cables in the cable dome structure are fixed on the peripheral statically-indeterminate ring truss structure to form an all-tension combination body. The shape of an overall structure is fixed by outer ring beams, an inner ring beam and a press rod. Afterprestressing force is acted upon the combination structure formed by the statically-indeterminate ring truss structure and the cable dome structure, the combination structure is shifted to be in an all-tension state. Therefore, the overall structure is balanced. Finally, purposes of achieving large-span space, low-weighted overall structure, damping and earthquake resistance are fulfilled.

Description

technical field [0001] The invention relates to a composite structure, in particular to a composite structure formed by a statically indeterminate ring truss structure and a cable dome structure. Background technique [0002] Problems existing in the existing cable dome structure: ① heavy and bulky compression ring beam; ② the upper layer cable is easy to slack and withdraw from work; The connection of the roof covering is more complicated and so on. Contents of the invention [0003] In order to solve the above problems, the present invention provides a combined structure formed by a statically indefinite ring truss structure and a cable dome structure, including a peripheral statically indeterminate ring truss structure and a cable dome structure, and the peripheral statically indeterminate ring truss structure includes a load-bearing Pier 1, load-bearing column 2, strut 3 and truss rod 4; the cable dome structure includes upper chord ridge cable 5, lower chord cable 6,...
