Integrated tension cable-diaphragm structure of back cable open type and construction method thereof

Abstract

The invention provides an integrated tension cable-diaphragm structure of back cable open type and a construction method thereof. The tension cable-diaphragm structure comprises a dorsal chord, a vale cable, an interior cable composed of loop cables, and a dorsal cord set composed of an exterior spinal cord, a lateral spinal cord, and an inhaul cable and the like cable components arranged on the outer ring, tension modus holding stiffness is formed by the dorsal cord set, a connection point is provided for the dorsal chord by a mast, elevation difference is generated by the dorsal chord and the vale cable, vertical stiffness is generated by the overall structure and load capacity is provided. By the arrangement of the mast and the dorsal system, a radial cable and an outer ring steel structure are auto-balanced with an upper cable rod structure, the steel capacity of an annular girder is saved, the upper system is auto balanced in a circle direction, at the same time the former great moment at the top section of a lower strut structure is deducted, and the issue of big steel capacity of the exterior steel structure of a sports field with the indent tension cable-diaphragm structure is resolved. By the construction method of the integrated tension cable-diaphragm structure, a sub-step elevated integral tension construction method of the cable- diaphragm structure is adopted, the requirements of the shape of the programming structure after the completion of the reality outspread construction are met as pledged, and the whole construction process is manageable and efficient.

Description

technical field [0001] The invention relates to a composite tensioned cable-membrane structure, in particular to an open-type integral tensioned cable-membrane structure with a back cable system and a construction method thereof. Background technique [0002] The tensioned cable-membrane structure is a structural system that relies on the tension of the membrane itself and the cables. The structure is mainly composed of a cable system and a covered membrane. In this type of structure, the membrane is fully tensioned and can withstand a certain load. The membrane can also act as a connection between the levels of the structure, and has a good absorption effect on earthquake and wind loads in the horizontal direction. Tensioned cable-membrane structures can be divided into: [0003] (1) General tensioned cable-membrane structure. The membrane is the main stress-bearing part. This structure makes the membrane have a certain rigidity by applying a certain prestress to the mem...

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of open-type overall tensioned cable membrane structure and its construction method with back cable, to solve the need for large height difference between the ridge cable and the valley cable of the inner concave tensioned cable membrane structure stadium, and the need for peripheral steel The technical problems of high overall rigidity requirements of the structure and the large amount of steel used for the surrounding steel structure have also been solved.
