Embodiment Construction

[0022] combine Figure 1-4 , to further describe the preferred examples of the present invention in detail.

[0023] A preferred example of the present invention is a stadium structure with a retractable roof, which is composed of a fixed roof 2, a movable roof 1 and a mechanical drive system. The long axis span of the fixed roof 2 is 260m, and the short axis span is 200m. The long main trusses 3 are arranged along the moving track of the movable roof, and the short main trusses 4 are arranged in a direction perpendicular to the long main trusses, thereby forming a "well"-shaped two-way three-dimensional main truss. The movable roof 1 is composed of two unit blocks, adopts a planar truss structure, and a total of 14 trusses are arranged along the span direction. The opening area is 12,350 square meters, and the opening or closing is realized by the hoist and the upper self-driven trolley 5.

[0024] Considering the stress characteristics of the structure during the opening ...

Abstract

The invention belongs to the field of building structures of retractable roofs, and particularly relates to a method for constructing movable structures of retractable roof systems. The method includes steps of 1), determining ajar states; 2), lifting the movable structures; 3), fixedly connecting supports; 4), adjusting vertical force of trolleys; 5), debugging the movable structures to open and close the movable structures. The method has the advantages that the movable structures are mounted in the ajar states, accordingly, the problem of difficulty in detaching bending rods of mounting cranes in fully-closed states can be solved, the construction efficiency can be improved, and the construction cost can be reduced; the movable structures are welded after the supports are connected, the movable structures and the mechanical trolleys are integrally mounted, accordingly, mounting deviation of center points of the supports of the movable structures can be eliminated, the center lines of the supports of the movable structures assuredly coincide with the center lines of the mechanical trolleys, and the mounting precision can be guaranteed.

Description

technical field [0001] The invention belongs to the field of retractable roof building structures, and in particular relates to a construction method for a movable structure of a retractable roof system. Background technique [0002] The retractable roof structure is a new type of building that can automatically open or close the roof within a controllable time. It breaks the boundaries between indoor and outdoor spaces and is multifunctional. It can integrate sports events, exhibition functions and performing arts. Due to its unique use function, it will become a development trend to choose open roof structure in future large public buildings. [0003] According to the current level of construction technology, the installation of movable structures can adopt construction methods such as direct hoisting by large cranes, overall vertical in-situ lifting, and high-altitude scaffolding installation. Obviously, the overall vertical lifting and the installation of high-altitude ...
