Problems solved by technology

Since the middle of the stadium is often an open field, the roof is a curved surface with large openings. If the middle part of the rigid upper chord of the tension string structure is set as a large opening structure, the upper chord cannot form a complete shell. To obtain the required rigidity and Bearing capacity is very difficult to design. Therefore, there are no relevant reports on the application of tension grid system to open-air stadiums in the world.

Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the technology of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0024] Such as figure 1 and 2 As shown, a large-opening spoke-type cable-supported grid structure includes an upper chord rigid grid system and a lower chord tensioned cable rod system. The upper chord rigid grid system and the lower chord tensioned cable rod system are connected to the outer ring beam Hinged, the outer ring beam 7 is fixedly connected with the support system 8 .

[0025] Such as Figure 3-9 As shown, the upper chord rigid grid system has a large opening structure in...

Abstract

The invention discloses a large opening car spoke type cable supported grid structure which comprises an upper chord rigid grid system and a lower chord tensioning cable-strut system. The upper chord rigid grid system is a structure with a large opening in the middle, and the lower chord tensioning cable-strut system comprises a strop and a plurality of radial tensioning cables, wherein the strop is correspondingly arranged below the opening of the upper chord rigid grid system, and the radial tensioning cables are arranged in a car spoke type in the radial direction of the strop. the end portion of each radial tensioning cable is hinged to the strop, a supporting rod is arranged between the radial tensioning cables and the upper chord rigid grid system in the arrangement direction of the redial tensioning cables, and a diagonal web member is arranged between the strop and the upper chord rigid grid system in the ring direction of the strop. By means of the large opening car spoke type cable supported grid structure, the high strength material characteristic of the tensioning cables is fully used, the cantilever stress state of the upper chord rigid grid system is changed to the stress state of an elastic support continuous beam, the rigidity of the overall structure is guaranteed, building material is saved, and the attractive architectural effect is achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a large-opening spoke-type cable-supported grid structure suitable for stadiums. Background technique [0002] The string structure has been used in Europe and Japan for a long time. Because the steel beam was used for the winding string at first, it is called Beam String Structure in English. In 1986, Professor Masao Saitoh of Nihon University defined this structure as "stretching the string and combining it with the beam", which is called the string beam. The string structure built earlier, such as a kindergarten gym in Japan, used string beams arranged in parallel. The plane size is 26m×36m. The Nihon University Gymnasium designed by Professor Masao Saitoh also uses parallel string beams with a plane size of 58m×85m. [0003] In recent years, the application of string beams has become more and more extensive. The form of the upper string has also developed fr...
