[0029] Please refer to Figure 1-Figure 4 This embodiment provides a retractable roof structure system, including:

[0030] The fixed roof 100 includes a dome roof 110 and a plurality of main diameter beams 120. The plurality of main diameter beams 120 are distributed under the dome roof 110 in an umbrella-like shape along the circumference of the dome roof 110. One end of the main diameter beam 120 is connected to the dome roof 110, and the other end is fixed to the foundation. The center of the dome roof 110 has a circular opening 111.

[0031] The retractable roof 200 is disposed on the fixed roof 100 and is composed of a plurality of petal-shaped movable roof units 210 . The movable roof units 210 can move along the radial direction of the fixed roof 100 to open or cover the circular opening 111 .

[0032] By driving the movable roof unit 210 to move radially along the fixed roof 100 to open or cover the circular opening 111, the venue can achieve mutual conversion between indoor and outdoor spaces, thereby making full use of natural conditions. It has the advantages of novel opening and closing methods, reasonable structural force, convenient driving and control, etc., enriching the structural form of the retractable roof structure system, and is suitable for both new buildings and functional improvement of existing sports venues, and has good application prospects.

[0033] In this embodiment, please refer to Figure 5 The main diameter beam 120 includes a bifurcated column 121 and a steel beam 122. The bottom end of the bifurcated column 121 is fixed on the foundation 300, and the top end of the bifurcated column 121 is connected to the dome roof 110 through the steel beam 122. The main function of the main diameter beam 120 is to support the entire dome roof 110 and the retractable roof 200. The design of the bottom bifurcated column 121 improves the stability of the support. In this embodiment, the steel beam 122 adopts an arc-shaped design.

[0034] Please continue to refer to Figure 5The bifurcated column 121 includes a reinforced concrete component and a box-shaped steel frame embedded in the reinforced concrete component, the box-shaped steel frame extends to the top of the reinforced concrete component and is welded to the bottom of the steel beam 122. The box-shaped steel frame is embedded in the pre-embedded box to facilitate the connection between the reinforced concrete component and the steel beam 122, while increasing the mechanical properties of the bifurcated column 121.

[0035] Preferably, the fixed roof 100 further includes an external tie ring beam 130, which is circumferentially arranged at the top ends of all the bifurcated columns 121. The external tie ring beam 130 is used to improve the overall rigidity and stability of the roof structure, reduce the displacement and vibration of the fixed roof 100, and resist deformation under non-uniform loads.

[0036] Optionally, the outer ring beam 130 is a steel strand, a cable or a steel member, which is not limited in the present invention. Preferably, the outer ring beam 130 is a cable to form a ring cable roof structure system. This structure system improves the rigidity of the entire roof by pre-tensioning the cable, thereby reducing the displacement and vibration of the roof, and can maintain a stable shape under non-uniform loads.

[0037] Please continue to refer to Figure 3-Figure 4 The dome roof 110 is a dome-shaped grid structure formed by connecting an internal pressure ring beam, a plurality of secondary ring beams, a plurality of secondary radial beams and a plurality of lace beams. Specifically, in this embodiment, the internal pressure ring beam is located at the top of the dome roof 110, a plurality of secondary ring beams are arranged along the circumferential direction of the dome roof 110, a plurality of secondary radial beams are arranged along the radial direction of the dome roof 110, and the lace beams are arranged at the outer edge of the dome roof 110 in an arc shape.

[0038] Please continue to refer to Figure 1-Figure 2 , the movable roof unit 210 corresponds to the main diameter beam 120 one by one and is movably arranged on the corresponding main diameter beam 120, and the movable roof unit 210 can move along the extension direction of the main diameter beam 120. In this embodiment, the center of the dome roof 110 has a circular opening 111, and the movable roof unit 210 can move along the extension direction of the main diameter beam 120 to switch between an open state and a closed state. In the open state, the circular opening 111 is fully exposed; in the closed state, the retractable roof 200 covers the circular opening 111 to form a closed dome structure.

[0039] In this embodiment, the number of the movable roof units 210 is an integer multiple of 3.

[0040] Exemplarily, the movable roof unit 210 is 12 pieces, and the top angle of each movable roof unit 210 is 30°. Each movable roof unit 210 can move independently, and can also be opened and closed synchronously. Tracks can be set on both sides of the main diameter beam 120, and each movable roof unit 210 is provided with a track beam, and each track beam corresponds to two tracks. By setting a corresponding driving mechanism such as a trolley, the movable roof unit 210 can be driven to move along the extension direction of the main diameter beam 120, and the present invention is not limited to this.

[0041] In this embodiment, the movable roof unit 210 is a pipe truss structure.

[0042] Furthermore, the outer surface of the movable roof unit 210 is covered with a metal skin, such as an aluminum-magnesium-manganese plate, which is not limited in the present invention.

[0043] In this embodiment, the construction steps of the retractable roof structure system are roughly as follows:

[0044] S1, first pouring the bifurcated column 121 and completing curing;

[0045] S2, temporarily supporting the field core and hoisting the internal pressure ring beam of the dome roof 110;
