[0002] Large-span spatial structures have been one of the fastest-growing structural forms in the past three decades, widely used in large public buildings such as transportation hubs, stadiums, and convention centers. With advancements in building technology, prefabricated spatial structure systems, especially modular spatial structure systems, have experienced rapid development due to their unique advantages. Modular spatial structure systems, with their factory prefabrication, rapid on-site assembly, high processing precision, ease of transportation and storage, and disassembly and reuse, significantly improve the level of building industrialization and exhibit higher material and time efficiency compared to traditional "member-node" systems.

[0003] Furthermore, with the diversification of social needs, there is a growing demand for buildings that can be rapidly assembled, used for short periods, and are easily disassembled and reused, such as temporary exhibition halls and emergency rescue facilities. These specialized buildings require rapid assembly, short-term use, and a high degree of disassembly and reuse. Traditional building systems are inadequate in meeting these demands, exhibiting problems such as slow assembly speed, inconvenient disassembly, and low reuse rates. Modular spatial structure systems precisely meet these needs, offering not only rapid assembly and convenient disassembly but also high reuse rates, effectively overcoming the limitations of traditional building systems in addressing such requirements. The development of modular spatial structure systems has provided the construction industry with efficient and flexible solutions, driving innovation and progress in building technology.

[0045] Figure 1 The schematic diagram illustrates the structure of a modular mesh system according to an embodiment of the present disclosure.

[0046] According to embodiments of this disclosure, a modular mesh system is provided, such as... Figure 1 As shown, the system includes multiple modular units 1, which are arranged sequentially in rows and / or columns in the same plane. Each modular unit 1 includes an integrally formed upper chord 11 and lower chord 12, as well as a web member 13. The web member 13 is adapted to connect the upper chord 11 and the lower chord 12 and to transmit loads. The upper chords 11 of adjacent modular units 1 are configured to be detachably connected, and a cable 2 is provided between the lower chords 12.

[0047] According to the above arrangement, each module unit 1 includes an upper chord 11, a lower chord 12, and a web member 13. The upper chords 11 of adjacent module units 1 are detachably connected, significantly improving the disassembly and repeatability of the building structure using this modular grid system. The lower chords 12 of adjacent modules 12 are connected by cables 2. Using cables 2 can maximize the saving of steel consumption in the grid system and maximize material strength. Arranging the module units 1 sequentially in the same plane ensures the stability of the structure and enables rapid installation and disassembly, thereby greatly improving the flexibility of building use and material utilization, and meeting the modern construction industry's demands for high efficiency, environmental protection, and adaptability.

[0048] In one illustrative embodiment, the cable 2 can be in the form of a steel wire bundle, steel strand, steel wire rope or steel tie rod, etc., wherein the mechanical performance parameters and structural requirements of the cable 2 can be determined according to the "Technical Specification for Design of Cable Structure Joints in Buildings".

[0049] Figure 2 The schematic diagram illustrates the structure of a module unit according to an embodiment of the present disclosure.

[0050] In one illustrative embodiment, such as Figure 2 As shown, the upper chord 11 includes two upper chord bars 111 arranged in a cross configuration, with the intersection of the two upper chord bars 111 located at the center of the upper chord bars 111.

[0051] In one illustrative embodiment, such as Figure 2 As shown, the upper chord 111 includes a hollow square bar.

[0052] According to the above arrangement, the upper chord 11 is composed of two hollow square upper chord rods 111 arranged in a cross configuration, with the cross position located at the center. This structure ensures the overall stability of the module unit 1, and also effectively reduces the structural weight due to the use of hollow square rods.

[0053] Among them, the square-section upper chord 111 can provide a larger bending moment of inertia, making it suitable for structures subjected to large bending moments.

[0054] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the two upper chords 111 are constructed in an orthogonal cross shape, and the intersection is connected by welding.

[0055] According to the above configuration, the cross-shaped upper chord 11, formed by two upper chord members 111, constitutes the upper orthogonal grid of the large-span spatial grid structure. Combined with the oblique grid formed by the lower chord 12 connected by cables 2, a good spatial force-bearing system is formed. This system not only has a large open space but also uses less steel and has good load-bearing performance. Under vertical loads, the upper chord 11 is under compression, and the lower chord 12 is under tension, resulting in high material strength utilization.

[0056] In one illustrative embodiment, such as Figure 2 As shown, the web member 13 includes: a vertical web member 131, which is located at the intersection of the two upper chord members 111 and is perpendicular to both upper chord members 111; and a diagonal web member 132, which is located between the end of the vertical web member 131 away from the upper chord 11 and the upper chord members 111.

[0057] In one illustrative embodiment, such as Figure 2 As shown, module unit 1 includes four diagonal web members 13.

[0058] According to the above arrangement, module unit 1 further enhances the stability and load-bearing capacity of the structure through four diagonal web members 132 and one vertical web member 131. The vertical web member 121 is located at the intersection of the two upper chord members 111 and is perpendicular to them, which not only enhances the stability of the structure but also provides effective support. One end of the diagonal web member 132 is connected to the end of the vertical web member 131 away from the upper chord 11, and the other end is connected to the upper chord member 111, forming a stable triangular support structure. The arrangement of the diagonal web members 131 helps to distribute and transfer loads, reducing stress concentration in individual members, thereby improving the stability and seismic resistance of the entire module unit 1. A triangle is one of the most stable geometric shapes in nature; the triangular support structure formed by the diagonal web members 132, the vertical web member 131, and the upper chord member 111 can effectively resist external loads and enhance the load-bearing capacity of the module unit.

[0059] In one illustrative embodiment, such as Figure 2 As shown, the lower chord 12 includes a connecting plate 121, which is installed at the end of the vertical web 131 away from the upper chord 11. The connecting plate 121 is provided with a connecting hole 1211 suitable for connecting the cable 2.

[0060] In detail, the connecting plate 121 is provided with four connecting holes 1211. In the projection on the horizontal plane, the connecting holes 1211 and the ends of the upper chord 111 are spaced apart along the circumference of the connecting plate 121.

[0061] According to the above configuration, the connection plate 121 and the connection hole 1221 thereon facilitate the connection of the cable 2, thereby realizing the connection of the cable 2 between the lower chords 12.

[0062] In one illustrative embodiment, such as Figure 2 As shown, both the vertical web member 131 and the diagonal web member 132 are constructed as hollow square bars with the same width as the upper chord member 111.

[0063] In one illustrative embodiment, the upper chord 111, the vertical web 131, and the diagonal web 132 also include a circular tube, an I-shaped cross-section, and a triangular cross-section.

[0064] Based on the above configuration, circular cross-section bars have good compressive and torsional resistance and are suitable for various structural layouts; I-shaped cross-section bars can optimize material distribution, reduce weight while maintaining structural strength and stability; triangular cross-section bars have good geometric stability and are suitable for space frame structures.

[0065] In one illustrative embodiment, the materials used to manufacture the upper chord 111, the vertical web 131, and the diagonal web 132 include steel, aluminum alloy, titanium alloy, and composite materials such as carbon fiber reinforced plastic and glass fiber reinforced plastic.

[0066] Based on the above setup, the members of module unit 1 can be made of different materials according to structural design requirements, budget, durability requirements and construction conditions.

[0067] In one illustrative embodiment, the diagonal length of module unit 1 (i.e. the length of the upper chord 111) includes various specifications such as 3m, 2.4m and 1.5m, and the corresponding height of module unit 1 can be 1.5m, 1.2m and 0.75m respectively.

[0068] In one illustrative embodiment, such as Figure 1 As shown, the two upper chord rods 111 of each upper chord section 11 are of the same length.

[0069] In one illustrative embodiment, such as Figure 1 As shown, the modular grid system also includes multiple first connectors 3, which are constructed in a cross shape, and the ends of the first connectors 3 are fitted inside the upper chord 111.

[0070] Figure 3 for Figure 1 The diagram shows the connection structure of multiple modular units in the modular mesh system.

[0071] Detailed, such as Figure 1 and Figure 3 As shown, the first connector 3 is used to connect the opposite ends of the upper chords 111 of the four adjacent module units 1 to form an orthogonal grid system of a large-span spatial grid structure.

[0072] Based on the above setup, by using upper chords 111 of the same length and first connectors 3 with cross-shaped structures, efficient connection of adjacent module units 1 is achieved, forming an orthogonal grid system. This design not only ensures structural uniformity and connection strength and simplifies the installation process, but also facilitates maintenance and replacement. It is very suitable for large-span spatial structures and demonstrates excellent construction efficiency, structural stability and adaptability.

[0073] Figure 4 The schematic diagram illustrates the structure of a first connector according to an embodiment of the present disclosure.

[0074] In one illustrative embodiment, such as Figure 4 As shown, the first connector 3 includes two connecting parts configured orthogonally, and the connecting parts include two vertically placed connecting plates 31.

[0075] In detail, the two connecting plates 31 are set in parallel, the height of the connecting plate 31 is equal to the distance between the upper and lower inner walls of the upper chord 111, and the distance between the outer sides of the two parallel connecting plates 31 is equal to the distance between the left and right inner walls of the upper chord 111.

[0076] According to the above configuration, the first connector 3 is composed of two orthogonal connecting parts. Each connecting part includes two vertically placed parallel connecting plates 31. The height of these connecting plates 31 matches the distance between the upper and lower inner walls of the upper chord 111, and the distance between the outer sides of the two connecting plates 31 is equal to the distance between the left and right inner walls of the upper chord 111. This design ensures the precise fit between the connector 3 and the upper chord 111, realizes high-precision docking and stable connection of the structure, and improves the installation accuracy and structural integrity of the entire modular grid system.

[0077] In one illustrative embodiment, the first connector 3 includes two connecting rods configured orthogonally, the cross-sections of which are configured to have the same cross-sectional shape as the upper chord 111.

[0078] In detail, the outer wall dimension of the connecting rod is the same as the inner wall dimension of the upper chord 111, so that the end of the connecting rod 33 can extend into the end of the upper chord 111.

[0079] According to the above configuration, the first connector 3 includes two orthogonal connecting rods with the same cross-sectional shape as the upper chord 111. The outer wall dimensions of the connecting rods precisely match the inner wall dimensions of the upper chord 111, allowing the ends of the connecting rods to tightly extend into the ends of the upper chord 111. This achieves precise alignment between the connector and the upper chord 11, ensuring high precision and stability of the structure, while simplifying the installation process and improving construction efficiency and overall structural reliability.

[0080] In one illustrative embodiment, such as Figure 3As shown, the modular grid system also includes fastening bolts 4, which are suitable for connecting and fixing the first connector 3 and the upper chord 11.

[0081] Detailed, such as Figures 1 to 4 As shown, the end of the first connector 3 is provided with a first mounting hole 32, and the end of the upper chord 111 is provided with a connecting hole corresponding to the first mounting hole 32. The first mounting hole 32 and the connecting hole are used to install fastening bolts 4 so that the end of the first connector 3 is connected to the upper chord 111 of the upper chord 11, thereby enabling adjacent module units 1 to be detachably connected to form an orthogonal grid system.

[0082] In one illustrative embodiment, the fastening bolt 4 includes a blind-hole single-sided bolt.

[0083] Since the upper chord 111 is a closed section member with a small internal space, ordinary high-strength bolts cannot be used to fasten it inside the member. Therefore, single-sided bolts must be used. Blind hole single-sided bolts are small, quick to install, and can be disassembled without damage.

[0084] Figure 5 A schematic diagram of the structure of a second connector according to an embodiment of the present disclosure is shown. Figure 6 A schematic diagram of the structure of a modular mesh system according to another embodiment of the present disclosure is shown.

[0085] In one illustrative embodiment, such as Figure 5 and Figure 6 As shown, the modular grid system also includes multiple second connectors 5, which are constructed in an L-shape and are located between the upper chord portion 11 of two adjacent module units 1.

[0086] Detailed, such as Figure 6 As shown, in Figure 1 In the modular grid system shown, an L-shaped second connector 5 is installed between the outer walls of adjacent upper chords 111 of adjacent module units 1.

[0087] Based on the above configuration, the modular grid system is further equipped with multiple L-shaped second connectors 5. These connectors 5 are installed between the upper chords 11 of adjacent module units 1, specifically between the outer walls of adjacent upper chord members 111. This design of the L-shaped connectors 5 enhances the connection stability between the upper chord members 111, ensures precise alignment between module units 1 and the overall structural robustness, thereby improving the load-bearing capacity and seismic performance of the entire grid system.

[0088] In one illustrative embodiment, such as Figure 5As shown, the second connector 5 is provided with two second mounting holes 51, which are adapted to mate with the connecting holes on the upper chord 111 and / or the first mounting holes 32 on the first connector 3 to install the fastening bolts 4.

[0089] In one illustrative embodiment, such as Figure 1 and Figure 6 As shown, the first connector 3 is configured to cover the opening at the end of the upper chord 111 of the connected module unit 1, so that the inside of the upper chord 111 is not exposed.

[0090] According to the above configuration, the interior of the upper chord 111 can be sealed to prevent water and other liquids from entering the interior of the upper chord 111, thereby preventing corrosion and rust.

[0091] Figure 7 A schematic diagram of the structure of a modular mesh system according to yet another embodiment of the present disclosure is shown.

[0092] In one illustrative embodiment, such as Figure 7 As shown, the two upper chord rods 111 of each upper chord section 11 have different lengths.

[0093] In one illustrative embodiment, such as Figure 7 As shown, one of the upper chords 111 in each module unit 1 is longer than the other upper chord by the width of one upper chord 111.

[0094] In one illustrative embodiment, such as Figure 7 As shown, the longer upper chord 111 in each module unit 1 is detachably connected to the shorter upper chord 111 of the adjacent module units 1 along the row and / or column by a second connector 5 and a fastening bolt 4.

[0095] In detail, the ends of the longer upper chords 111 of two adjacent module units 1 along the extension direction of the longer upper chord 111 abut against each other, while the ends of the shorter upper chords 111 of two module units 1 in a direction orthogonal to the extension direction of the longer upper chord 111 abut against the outer wall of the longer upper chord 111.

[0096] According to the above configuration, the longer upper chord 111 of each module unit 1 is detachably connected to the shorter upper chord 111 of the adjacent module unit 1 via the second connector 5 and fastening bolts 4. The ends of the longer upper chord 111 of two adjacent module units 1 along the extension direction of the longer upper chord 111 abut against each other, while the end of the shorter upper chord 111 of the module unit 1 in the orthogonal direction abuts against the outer wall of the longer upper chord 111. This structural design not only provides flexibility in length for the modular grid system, but also enhances the adaptability and maintainability of the structure through the detachable connection method, while ensuring the stability and strength of the entire grid system under complex geometries.

[0097] It should also be noted that the modular grid system proposed in this disclosure can be applied to periodically used buildings such as disaster relief buildings and exhibition buildings. Figure 1 , Figure 6 and Figure 7 The modular mesh system shown exhibits different connection methods depending on the connectors or the upper chord 111. The number of components varies (using only the first connector 3 or the second connector 5, or both). Fewer components result in better disassembly, while more components improve load-bearing performance, making module unit 1 less prone to damage and improving reusability. Therefore, the chosen connection method can be determined by comprehensively considering actual disassembly and reusability requirements, project importance, number of connection nodes, and cost requirements.
