Embodiment Construction

[0022] In conjunction with Figures 1-4, the preferred examples of the present invention will be further described 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 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 mechanical trolley 5.

Abstract

The invention belongs to the field of opening and closing roof building structures, and in particular relates to a construction method for a movable structure of an opening and closing roof system, which comprises the following steps: 1) determining a slightly open state; 2) hoisting the movable structure; ; 4) Adjust the vertical force of the trolley; 5) Debug to open and close. The installation movable structure in the slightly open state proposed by the invention solves the difficulty in removing the squat rod of the installation crane in the fully closed state, improves the construction efficiency, and reduces the construction cost; the proposed connection support is welded after the connection and is installed in an integrated manner with the mechanical trolley. The installation deviation of the center point of the movable structure support is eliminated, the center line of the movable structure support and the center line of the mechanical trolley are overlapped, and the installation accuracy is ensured.

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 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 full-house s...
