This structure requires tie rods at the top, placing high demands on construction and design, and also affecting the canopy's aesthetics and usability. Traditional cantilevered canopies require tie rod support for extremely large spans. Therefore, this invention relates to a tie-rod-free, irregularly shaped cantilevered canopy for extremely large spans and its construction method, primarily solving the problem of traditional cantilevered canopies requiring tie rod support for extremely large spans.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] This invention utilizes software such as Tekla Structures to model and refine the design of the building structure and the cantilevered canopy. Addressing challenges such as difficulty in controlling beam end deflection, out-of-plane stability of single cantilevered frames, and handling the root joints of the cantilevered main beams, it rationally selects appropriate steel beam dimensions, employs an inverted arch structure, and strengthens lateral connections. Subspace iterative analysis is used for eigenvalue analysis, and the removal of key components is employed to perform progressive collapse resistance calculations on critical parts, ensuring that the structural non-collapse analysis results meet relevant requirements.

[0026] The building's main structure includes multiple cantilever beams and supporting columns. The cantilever beams feature an irregular cross-section design, enabling them to withstand greater loads during ultra-large spans. The supporting columns are responsible for supporting the weight of the cantilever beams and transferring it to the ground.

This invention provides a large-span, tie-free, irregularly shaped cantilevered canopy, comprising: multiple main trusses 10, which are arranged alternately on a main structure 20.

[0029] Two secondary trusses 11 are laterally connected between multiple main trusses 10.

[0030] The two secondary trusses 11 are arranged in parallel. The secondary trusses 11 are curved upward in the middle. The secondary trusses 11 correspond to the main trusses 10, with the middle being higher and the sides being lower.

The multiple second diagonal braces 112 are connected end to end, and the second vertical braces 113 are vertically connected to the connection points of the second diagonal braces 112, connecting the two upper and lower secondary beams 111 to form a whole.

[0051] See Figure 1 The image shows an elevation view of a large-span, tie-free, irregularly shaped cantilevered canopy. The present invention provides a large-span, tie-free, irregularly shaped cantilevered canopy, the supporting frame 12 including: a first support portion 121, which is disposed in the middle of a plurality of main trusses 10, and is arranged parallel to the main trusses 10.

[0052] One side of the first support 121 is connected to the side wall of the main structure 20, and the first support 121 is positioned higher than the multiple main trusses 10.

[0057] The third connecting component is vertically connected between the two first keels 1211.

[0058] The third connecting component includes multiple third diagonal rods 1212 and multiple third vertical rods 1213. The multiple third diagonal rods 1212 are connected end to end between two first keels 1211, and the third vertical rods 1213 are vertically connected to the connection points of the third diagonal rods 1212. The third diagonal rods 1212 and the third vertical rods 1213 connect the two first keels 1211 into a whole.

[0059] In this embodiment, the second support 122 includes a plurality of second keels and a plurality of fourth connecting components. The second keels are arranged parallel to each other vertically. The second keels are made of the same material as the first keel 1211.

[0061] The connector 123 is disposed on the upper main beam 101 and the lower main beam 102 of the main truss 10, and on the first keel 1211 of the first support part 121.

[0062] Multiple reinforcing rods 124 are supported on the main truss 10 and the first support part 121, and the two ends of the multiple reinforcing rods 124 are connected to the connectors 123 respectively.

[0063] The reinforcing rod 124 can be diagonally braced between the upper main beam 101 and the first keel 1211, or horizontally supported between the lower main beam 102 and the first keel 1211. The reinforcing rod 124 transfers and distributes the load-bearing capacity on the main truss 10 to the supporting frame 12, reducing the burden on the main truss 10 and improving the structural stability of the cantilevered canopy.

[0064] In this implementation method, for the main trusses 10 with longer lengths, reinforcement members 125 can be installed to connect and strengthen them. The reinforcement members 125 are connected in a Z-shape and support each other between adjacent main trusses 10, which strengthens the connection between the main trusses 10 and enables them to withstand larger loads.
