Problems solved by technology

Due to the complex structural design and difficult construction of the tensegrity, there is no mature theory on the design and construction of the ring tense unit, so it is rarely used in the field of civil engineering.
Levy-type cable dome has some design and construction experience at home and abroad, but the cable dome is mostly attached to the rigid boundary and becomes the roof of the stadium. There is no engineering example of the Levy-type cable dome under the flexible boundary condition.

Embodiment

[0021] Embodiment: A kind of full-tension cable-strut roof structure system of this embodiment is as follows image 3 As shown, it consists of a Levy-type cable dome and a ring-shaped tensegrity. The outer pressure rod 11 of the ring-type tensioner is connected to the middle pressure rod 8 on the edge of the Levy-type cable dome through a ball joint 12 .

[0022] Among them, the Levy type cable dome such as figure 1 As shown, it includes a central compression rod 1, twelve inner compression rods 2 and twelve middle compression rods 3, as well as ridge cables 4, upper radial cables 5, lower radial cables 6, inner ring cables 7, middle ring cables 8. The upper oblique cable 9 and the lower oblique cable 10, wherein the inner pressure rod 2 and the middle pressure rod 3 are respectively arranged on two concentric circles with the central pressure rod 1 as the center, and the two ends of the central pressure rod 1 are connected with the inner pressure rod The top end of the inner...

Abstract

The invention provides a full-tension cable-strut roof structural system and a construction method thereof. The structure comprises a Levy-type cable dome and a ring-shaped tension entirety, wherein the ring-shaped tension entirety is connected to the edge of the Levy-type cable dome; each middle pressure lever and two outer pressure levers of each group of outer pressure levers are connected to the common pitch point; common cables are connected between the middle pressure levers and the outer pressure levers. The construction method comprises the steps of form finding, assembling and connecting of the common pitch points and the common cables. The structural system and the construction method have the advantages of high material utilization, low construction cost and the like.

Description

technical field [0001] The invention relates to a prestressed structure of a building, in particular to a full-tension cable-strut roof structure system and a construction method thereof. Background technique [0002] With the continuous improvement of architectural design theory and structural design level, tensegrity structure and cable dome structure have gained more and more attention due to their flexible expressive force, light and dynamic architectural configuration and economical steel usage. s concern. Due to the complex structural design and difficult construction of the tensegrity, there is no mature theory about the design and construction of the ring tensegrity, so it is rarely used in the field of civil engineering. Levy-type cable dome has some design and construction experience at home and abroad, but the cable dome is mostly attached to the rigid boundary and becomes the roof of the stadium, and there is no engineering example of the Levy-type cable dom...
