Description

Technical Field

[0001] The invention relates to the field of large-span construction projects such as cable-structured stadiums, and in particular to a horizontal truss structure system supported by hinged columns. Background Art

[0002] The roof of a stadium project adopts a spoke-type cable truss structure with an elliptical boundary. Under the action of cable tension, the ring beam is subjected to uneven force and stiffness due to its elliptical shape, so that the ring beam not only bears a large axial pressure, but also bears a large bending moment in the horizontal direction, resulting in a large cross-sectional width of the ring beam, poor economic efficiency, and affecting the architectural effect and use. How to design a supporting structure system suitable for an elliptical boundary cable structure has become a technical problem that technicians in this field need to solve urgently.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides a horizontal truss structure system supported by hinged columns, comprising a horizontal ring truss, an inner ring column and an outer ring column; wherein:

[0007] The horizontal ring truss includes an inner ring beam, an outer ring beam and a cross beam system for connecting the inner ring beam and the outer ring beam; the horizontal ring truss is hingedly connected to the inner ring column through the inner ring beam, and the horizontal ring truss is hingedly connected to the outer ring column through the outer ring beam.

[0008] As a further technical solution, the inner ring beam is rigidly connected or hingedly connected to the cross beam system, and the outer ring beam is rigidly connected or hingedly connected to the cross beam system.

[0009] As a further technical solution, the intersection points of the inner ring beam and the cross beam system correspond one-to-one to the intersection points of the cable structure and the inner ring beam.

[0010] As a further technical solution, the inner ring columns are arranged in pairs in a V-shape, and the ends of two adjacent pairs of inner ring columns intersect at the same point of the inner ring beam.

[0011] As a further technical solution, the outer ring column is arranged individually.

[0012] As a further technical solution, the inner ring column and the outer ring column are both hinged columns at both ends.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects:

[0014] 1. The structural system provided by the present invention bears the tension of the cable structure through the overall action of the horizontal ring truss, and eliminates the local bending moment of the inner ring beam caused by the tension of the cable structure through the one-to-one correspondence between the horizontal ring truss nodes and the cable nodes. It has a clear idea and clear force transmission, and can reduce the cross-section of the ring beam, thus solving the problem of the prior art that the cross-section of the ring beam is large and affects the construction effect and use.

[0015] 2. In the structural system provided by the present invention, all supporting columns are hinged columns at both ends, which are simple to bear force and can make the column section design and lower structure design more convenient and reasonable.
