Description

Technical Field

[0001] This invention relates to the technical field of architectural design, specifically to a space frame and single-layer reticulated shell structure system suitable for column-free spaces. Background Technology

[0002] Modern public cultural buildings, such as theaters and art galleries, typically require interior spaces with significant span and height flexibility to meet functional needs such as stage setup, exhibition continuity, and audience flow. Traditional reinforced concrete or ordinary steel frame structures suffer from problems such as high material consumption, large structural thickness, and complex construction when realizing large-span column-free spaces.

[0003] In recent years, spatial structures such as space frames and grid shells have been increasingly applied to large public buildings. For buildings requiring column-free spaces, space frame structures perform better in handling large spans and multidimensional loads, but their overall shape is relatively simple and difficult to meet the requirements of complex curved surfaces. Grid shell structures can achieve complex curved surface requirements, but they have certain limitations in terms of stress and stability, and are insufficient in handling large spans and multidimensional loads. Therefore, neither simple space frame structures nor grid shell structures can meet the requirements of complex curved surfaces and large spans and multidimensional loads in column-free space buildings. Based on this, this application aims to provide a structural system combining grid shell structures and space frame structures to fully leverage the advantages of each structure and meet the requirements of complex curved surfaces and large spans and multidimensional loads in column-free space buildings. Summary of the Invention

[0004] Based on the above description, the present invention provides a space frame and single-layer space shell structure system suitable for column-free spaces, so as to give full play to the advantages of the space shell structure and the space frame structure respectively, and meet the requirements of large span and multi-dimensional load of column-free space buildings.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: This application provides a space frame and single-layer reticulated shell structure system suitable for column-free spaces, and the technical solution adopted is as follows: A space frame and single-layer reticulated shell structure system suitable for column-free spaces, comprising: The main structure includes an upper single-layer reticulated shell and a lower single-layer reticulated shell distributed vertically, both of which extend on a horizontal plane. The main structure includes a first region and a second region distributed on the horizontal plane. In the first region, the upper single-layer reticulated shell and the lower single-layer reticulated shell are connected by a linkage system to form a space frame structure; In the center of the second region, the lower single-layer mesh shell is recessed downward to form an annular outer wall supported on the ground, and the upper single-layer mesh shell is recessed downward to form an annular inner wall that passes through the annular outer wall and is supported on the ground. An annular space is formed between the annular outer wall and the annular inner wall.

[0006] Preferably, in the first region, the main body of the structure has a curved shape with its height gradually decreasing from the center to the surrounding area.

[0007] Preferably, curtain walls are provided on the outer surface of the annular outer wall and the inner surface of the annular inner wall, and the rods constituting the annular outer wall and the annular inner wall serve as curtain wall keels.

[0008] Preferably, the curtain wall on the inner side of the annular inner wall is a glass curtain wall.

[0009] Preferably, the curtain wall on the outer side of the annular outer wall is an aluminum panel curtain wall.

[0010] Preferably, the outer annular wall and the inner annular wall are connected by steel beams.

[0011] Preferably, at the edge of the second region, the upper single-layer mesh shell and the lower single-layer mesh shell are connected by the linkage system.

[0012] Preferably, the annular space is provided with a spiral ramp surrounding the annular inner wall, and the spiral ramp is connected to the annular inner wall.

[0013] Preferably, both the upper single-layer mesh shell and the lower single-layer mesh shell are triangular mesh structures.

[0014] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: 1. This application sets the main structure as consisting of an upper single-layer reticulated shell and a lower single-layer reticulated shell distributed vertically. The two single-layer reticulated shells constitute the main form of the building. Due to the use of a two-layer single-layer reticulated shell structure, it can be designed into various complex curved surfaces according to actual needs, thereby meeting the complex curved surface requirements of column-free space architecture. At the same time, according to the functional requirements of the building, the main structure is divided into two regions distributed on the horizontal plane: a first region and a second region. In the first region, the upper and lower single-layer reticulated shells are connected by a linkage system to form a space frame structure, which can achieve a larger span. The multi-directional force of the linkage system improves the stability under multi-dimensional loads, thus meeting the functional requirements of column-free large space architecture. In the second region, the upper and lower single-layer reticulated shells are recessed downwards at their centers, forming annular outer and inner walls supported on the ground, respectively. An indoor annular space is formed between these outer and inner walls. Thus, the main structure in the second region forms a double-layer reticulated shell structure with a complex curved shape. This double-layer reticulated shell structure offers better stress distribution and stability, exhibiting higher stability under multi-directional loads, meaning it better handles multi-directional loads while meeting the requirements of complex curved surfaces. The indoor annular space formed between the two layers of the reticulated shell structure fulfills the functional requirements of an annular interior space. Therefore, the structural system of this application, combining a space frame structure and a reticulated shell structure, can fully leverage the advantages of both structures, thereby meeting the needs of column-free spatial architecture for complex curved surfaces, large spans, multi-functional spaces, and multi-dimensional loads.

[0022] This embodiment provides a space frame and single-layer space shell structure system suitable for column-free spaces, aiming to give full play to the advantages of space shell structure and space frame structure to meet the requirements of complex curved surfaces, large spans and multi-dimensional loads of column-free space buildings.

[0023] Figure 1 This embodiment shows an overall structural diagram of a space frame and single-layer reticulated shell structure system suitable for column-free spaces, which includes a main structural body 1, wherein, referring to... Figure 2-3As shown, the main body of the structure 1 includes an upper single-layer reticulated shell 2 and a lower single-layer reticulated shell 3 distributed vertically. Both the upper single-layer reticulated shell 2 and the lower single-layer reticulated shell 3 extend on the horizontal plane. The main body of the structure 1 includes a first region 11 and a second region 12 distributed on the horizontal plane.

[0024] Specifically, the first area 11 and the second area 12 are designed according to the functional requirements of the building space, wherein, referring to Figure 2 As shown, in the first region 11, the upper single-layer reticulated shell 2 and the lower single-layer reticulated shell 3 are connected by a linkage system 4 to form a space frame structure.

[0025] Since the main structure 1 is formed by two single-layer reticulated shells, the upper single-layer reticulated shell 2 and the lower single-layer reticulated shell 3, it can be designed into various complex curved surfaces according to actual needs, thereby meeting the complex curved surface requirements of column-free space architecture.

[0026] Specifically, since the space frame structure performs better in dealing with large spans and multidimensional loads, the first region 11 is connected to the upper single-layer space shell 2 and the lower single-layer space shell 3 through the linkage system 4 to form a space frame structure. The multi-directional force of the linkage system 4 improves the stability under multidimensional loads, enabling it to have a large span and form a column-free large space roof, thus meeting the functional requirements of a column-free large space in the building.

[0027] Reference Figure 1 and Figure 2 As shown, further, in the first region 11, the main structural body 1 has a curved shape with its height gradually decreasing from the center to the surrounding area. That is, the main structural body 1 forms an upwardly convex space frame structure in the first region 11. The space frame structure is formed by stacking two single-layer space shell structures and adding a connecting rod system 4, which can effectively utilize the mechanical properties of the structural materials and give the space frame structure a lower spatial cross-sectional height.

[0028] The space frame structure connects the members of the two single-layer space shells into a whole through the linkage system 4, forming a structure that experiences forces along both the tangent and normal directions of the curved surface. Its mechanical characteristics offer great flexibility. Using the space frame structure as the roof creates a large, column-free space beneath the first area 11 of the main structure 1. The space frame structure can also provide support for the structures of the functional spaces below. For example, when the space beneath the first area 11 is used as a theater, the acoustic bridges, lighting bridges, reflective ceilings, single-point suspensions, and some equipment pipelines of the auditorium can be suspended from the roof of the space frame structure, fully utilizing the spatial and mechanical characteristics of the space frame structure and improving structural utilization.

[0029] Reference Figure 1 , Figure 2 and Figure 3As shown, in the center of the second region 12, the lower single-layer mesh shell 3 is recessed downward to form an annular outer wall 31 supported on the ground, and the upper single-layer mesh shell 2 is recessed downward to form an annular inner wall 21 that passes through the annular outer wall 31 and is supported on the ground. An annular space is formed between the annular outer wall 31 and the annular inner wall 21.

[0030] In this structure, the span of the first region 11 of the main body 1 is greater than the span of the second region 12. Based on the two-layer single-layer reticulated shell structure, the structural system forms a natural transition between the reticulated frame and the single-layer reticulated shell structure at the connection between the first region 11 and the second region 12, integrating mechanical properties with spatial functions to create a reticulated frame and single-layer spatial reticulated shell structure system suitable for large, column-free spaces.

[0031] Specifically, based on the building design of the ground below, the outer ring wall 31 and the inner ring wall 21 can be directly connected to and supported on the ground, or connected to and supported on the building below, so that the bottom of the outer ring wall 31 and the inner ring wall 21 can be effectively supported and fixed.

[0032] The main structure 1 forms a double-layered reticulated shell structure with a complex curved shape in the second region 12. The double-layered reticulated shell structure has better stress distribution and stability, and higher stability under multi-directional loads, that is, it has better performance in coping with multi-directional loads while meeting the requirements of complex curved surfaces. Moreover, the indoor annular space formed between the two layers of the reticulated shell structure can meet the functional requirements of an annular indoor space.

[0033] Reference Figure 3 As shown, both the annular outer wall 31 and the annular inner wall 21 are cylindrical with their axes perpendicular to the ground, and are connected to the corresponding single-layer reticulated shell by an arc surface to optimize the structural stress and improve stability.

[0034] Reference Figure 2 As shown, further, at the edge of the second region 12 away from the first region 11, the edge of the lower single-layer reticulated shell 3 extends upward to connect with the edge of the upper single-layer reticulated shell 2 to form an integral whole. Furthermore, at the edge of the second region 12, the upper single-layer reticulated shell 2 and the lower single-layer reticulated shell 3 are connected by a linkage system 4. This further connects the lower single-layer reticulated shell 3 and the upper single-layer reticulated shell 2 in the second region 12 to form an integral whole, resulting in a double-layer reticulated shell structure that acts as a complete closed whole, resulting in greater stress balance.

[0035] The outer ring wall 31 and the inner ring wall 21 are also connected by steel beams. The steel beams are arranged along the axial direction of the ring space. The specific parameters and number of steel beams are designed according to actual needs to further improve the structural stability.

[0036] In the design, the column-free circular space formed between the outer ring wall 31 and the inner ring wall 21 offers greater design freedom and can meet various spatial functional requirements. Specifically, to achieve vertical circulation within the circular space, a spiral ramp is installed around the inner ring wall 21. The spiral ramp connects to the inner ring wall 21, and its function as a vertical circulation channel is more aesthetically pleasing. In the design, the circular space can be vertically divided into multiple levels, with the spiral ramp connecting these levels, creating an exhibition and tour space based on an inner courtyard and the inner spiral ramp, which can meet the functional requirements of column-free exhibition spaces such as art galleries.

[0037] Furthermore, curtain walls are provided on the outer surface of the annular outer wall 31 and the inner surface of the annular inner wall 21, and the members constituting the annular outer wall 31 and the annular inner wall 21 serve as curtain wall keels. The members of the single-layer grid shell structure also serve as curtain wall keels, and the keel claws are directly welded to the intersections of the members, which greatly reduces the number of secondary components, improves material utilization, and forms a lightweight, transparent, and highly tough enclosure system.

[0038] Specifically, the inner side of the inner ring wall 21 is a glass curtain wall, which gives the ring space a large lighting surface and meets the lighting requirements of the ring space. The outer side of the outer ring wall 31 is an aluminum panel curtain wall, which serves as an exhibition space for artificial lighting. The lighting system for the space under the roof of the outer ring wall 31 is arranged on the aluminum panel curtain wall to maximize the exhibition space.

[0039] Specifically, in this embodiment, both the upper single-layer reticulated shell 2 and the lower single-layer reticulated shell 3 are triangular mesh structures. The triangular mesh structure creates a mechanically stable self-supporting system for the structural members, providing excellent lateral stiffness and deformation control. By combining and separating the two single-layer reticulated shell structures, a space frame roof suitable for column-free large spaces and a single-layer reticulated shell enclosure system suitable for column-free large spaces are formed.

[0040] Taking the area below Zone 11 as a theater and the circular space as an art museum as an example, the structural system of this embodiment can meet the functional requirements of a theater with a high stage, a transparent circular hall, and an art museum with a cohesive exhibition space. While meeting the requirements of the city's image, the theater and art museum are integrated into one, using a convex and concave architectural form to create a complete architectural image, while allowing the theater and art museum to operate independently. The area between Zone 11 and Zone 12 can be designed as an outdoor space, thus forming a corridor that allows passage through the city between the theater and the art museum.

[0041] Within the circular space, the vertical division into multiple exhibition areas is achieved. Steel beams serve as the floor support system, maximizing their structural support. Spiral ramps connect these areas, creating a vertical visitor flow. The circular space functions as an art museum, employing both glass and aluminum panel curtain walls. These systems complement the museum's inward-facing spatial characteristics. Naturally lit circulation and interaction spaces are arranged around the interior, with the glass curtain walls providing ample natural light to meet the exhibition space's lighting requirements. The single-layer grid shell structure's members also function as the curtain wall's framework, significantly improving material utilization efficiency. Only secondary frameworks are needed to accommodate the curtain wall unit dimensions, resulting in a simple and lightweight glass curtain wall enclosure structure.

[0042] The cylindrical structure of the outer ring wall 31 and the inner ring wall 21 is connected at the top to form an integral structure. Combined with steel beams and spiral ramps, it forms a composite structural system with sufficient stability and meets the spatial functional requirements of the art museum.

[0043] The space frame and single-layer reticulated shell structure system applicable to column-free spaces in this embodiment uses two single-layer reticulated shells to form the main building shape. A convex curved surface is formed in the first region 11, and a complex double-layer cylindrical curved surface is formed in the second region 12, resulting in a complex curved shape for the entire building. The first region 11 forms a large-span reticulated shell structure, satisfying both the requirements of the complex curved surface and the needs of a large-span column-free space and multi-dimensional loads. The double-layer reticulated shell structure in the second region 12 satisfies the requirements of the complex curved surface and also has better performance in handling multi-directional loads. Therefore, the structural system of this embodiment combines space frame and reticulated shell structures, fully leveraging the advantages of each to meet the needs of column-free space buildings for complex curved surfaces, large spans, multi-functional spaces, and multi-dimensional loads.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
