Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a bamboo-rib joint umbrella-shaped building structure. Background Technology

[0002] With the continuous development of spatial structure technology in my country, large-span spatial structures are widely used in the architectural design of public places such as airport terminals, stadiums, and convention centers, resulting in increasingly diverse architectural styles. Existing large-span spatial structures generally employ large-span steel structures, which are typically supported by concrete or steel structures via ball joints. However, reinforced concrete building materials have high technical requirements, high production costs, and are not considered environmentally friendly materials. Furthermore, the maintenance costs of large-span steel structures are also relatively high. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bamboo-joint umbrella-shaped building structure that utilizes the original structure and physical properties of bamboo to form a building structure with high strength, large span, low energy consumption, green environmental protection, and a sense of intimacy. This reduces the technical requirements for building material manufacturing, production costs, and maintenance costs. Moreover, it is a green and environmentally friendly material that combines technological breakthroughs with ecological value.

[0004] To achieve the above objectives, one embodiment of this utility model provides a bamboo-joint umbrella-shaped building structure, comprising: a column, formed by multiple supporting rods, the column being fixed to the lower main structure or foundation, the supporting rods being assembled from multiple bamboo joint modules; and multiple branched columns, fixed to the column and arranged radially from the column to form an umbrella-shaped structure, the branched columns being assembled from multiple bamboo joint modules, with reinforcing ribs forming a grid between adjacent branched columns, and skylights provided within the grid; wherein each bamboo joint module can be independently assembled and disassembled, each bamboo joint module including at least one bamboo segment, and the joints between adjacent bamboo joint modules are connected by mortise and tenon joints or by bio-adhesive.

[0005] The above technical solution utilizes a bamboo-joint umbrella-shaped building structure. The columns are formed by multiple supporting rods, each composed of multiple bamboo joint modules. Multiple branching columns 13, also composed of bamboo joint modules, are fixed to the columns and arranged radially from the columns to form an umbrella-like structure. Adjacent branching columns are connected by reinforcing ribs to form a grid. Each bamboo joint module can be independently assembled and disassembled. The joints between adjacent bamboo joint modules are connected using mortise and tenon joints or adhesive. Utilizing the original structure and physical properties of bamboo, a high-strength, large-span, low-energy-consumption, environmentally friendly, and approachable building structure is created. This reduces the technical requirements, production costs, and maintenance costs of building materials, and, being a green and environmentally friendly material, combines technological breakthroughs with ecological value. By mimicking the natural joint structure of bamboo and using segmented bamboo joint modules, a bamboo-joint biomimetic design is achieved, combining lightweight and high strength. The natural fiber distribution of bamboo joints optimizes mechanical properties, while the use of mortise and tenon joints or bio-adhesive bonding technology at splicing nodes reduces metal connectors and improves overall integrity. At the same time, the natural weather resistance and structural self-stability of bamboo reduce the need for long-term maintenance, effectively lowering maintenance costs. This achieves three-dimensional spatial topology optimization, dynamic stress adjustment, modularity and scalability, energy and ecological integration, architectural aesthetic expression, low-carbon manufacturing process, and low maintenance costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please refer to the following: Figures 1-3 ,in, Figure 1 A schematic diagram of the bamboo-rib joint umbrella-shaped building structure provided in an embodiment of this utility model; Figure 2 This is a schematic diagram of a bamboo joint module provided in an embodiment of the present invention; Figure 3 A perspective view of a bamboo-ribbed umbrella-shaped building structure provided in an embodiment of this utility model.

[0020] like Figures 1-3 As shown, the bamboo-joint umbrella-shaped building structure described in this embodiment includes: a column 11 and multiple branch columns 13. The column 11 is formed by multiple support rods 111, and the column 11 can be fixed to the lower main structure 10 or the foundation. The support rods 111 are spliced ​​together from multiple bamboo joint modules 12. The multiple branch columns 13 are fixed to the column 11 and arranged radially from the column 11 to form an umbrella-shaped structure. The branch columns 13 are also spliced ​​together from multiple bamboo joint modules 12. Adjacent branch columns 13 are connected by reinforcing ribs 14 to form a grid, and skylights 15 are provided in the grid. Specifically, each bamboo joint module 12 can be independently assembled and disassembled. Each bamboo joint module 12 includes at least one bamboo segment. The splicing nodes 121 of two adjacent bamboo joint modules 12 are connected by mortise and tenon joints or by biological adhesive.

[0021] In this embodiment, the bottom of the column 11 may adopt a ball joint support, pin connection or other hinge form to achieve a fixed connection with the lower main structure or foundation position.

[0022] Each bamboo joint module 12 can be independently assembled and disassembled. Its modularity and scalability make it suitable for diverse scenarios such as large-span temporary buildings (e.g., exhibition halls, emergency shelters) and ecological landscape facilities (e.g., park pavilions, bus stop shades). The natural texture and jointed arrangement of bamboo create a unique oriental aesthetic, and the structure itself can serve as a public art installation. All the branched columns 13 are connected as a whole by the reinforcing ribs 14. It should be noted that the diameter and height of the columns 11, the distribution of the branched columns 13, and the structure and shape of the reinforcing ribs 14 in this embodiment can be adaptively selected according to architectural requirements.

[0023] Bamboo is characterized by rapid growth and short rotation periods. It possesses high strength, good toughness, high hardness, and a dense outer layer with a sparse inner layer, offering significant advantages for biomimetic research. my country boasts the world's largest variety of bamboo species, bamboo forest area, and bamboo stock, making it one of the countries with the richest bamboo resources globally. Replacing traditional metal or plastic frames with rapidly regenerating bamboo allows for the effective reduction of carbon footprint through sustainable material applications. Furthermore, bamboo's natural tensile strength (up to 60% of steel) and flexibility perfectly match the dynamic requirements of umbrella-shaped structures. By fully utilizing bamboo's original structural and physical properties, along with the prestressing effect of reinforcing materials, it can be processed into high-strength, large-span, low-energy-consumption, environmentally friendly, and user-friendly structural materials. This can effectively alleviate the supply and demand imbalance of concrete and steel materials, offering broad development and application prospects. Mimicking the natural segmented structure of bamboo, a segmented bamboo joint module splicing method achieves a bamboo-joint biomimetic design, combining lightweight with high strength. The natural fiber distribution of bamboo joints optimizes mechanical properties, while the use of mortise and tenon joints or bio-adhesive bonding technology at the splicing nodes reduces metal connectors and improves overall integrity; at the same time, the natural weather resistance and structural self-stability of bamboo reduce the need for long-term maintenance and effectively lower maintenance costs.

[0024] In some embodiments, the bamboo joint module 12 uses raw bamboo that has undergone high-temperature carbonization treatment. Raw bamboo refers to bamboo with a natural joint structure. Hollow raw bamboo is processed into bamboo joint modules after high-temperature carbonization treatment. The raw bamboo has anti-insect and anti-corrosion effects after high-temperature carbonization treatment, requiring no chemical coating. Moreover, the structure can be completely biodegraded or disassembled and recycled after being scrapped, meeting the requirements of low-carbon manufacturing process.

[0025] In this embodiment, multiple support rods 111 are joined together to form a cylindrical column 11, the diameter of which gradually increases from bottom to top. That is, the cross-section of the column 11 can be of uniform cross-section or gradually decrease from top to bottom. Since each bamboo joint module 12 can be independently assembled and disassembled, and the natural tensile strength of bamboo (up to 60% of that of steel) and flexibility perfectly meet the dynamic requirements of the umbrella-shaped structure, by fully utilizing the original structure and physical properties of bamboo and the prestressing tension of the reinforcing material, partial bending of the support rods 111 can be achieved, so that the diameter of the column 11 gradually increases from bottom to top. Multiple branched columns 13 gradually open outward from the top of the column 11 to form an umbrella-shaped structure, and the multiple branched columns 13 are connected as a whole by reinforcing ribs 14, thereby forming a bamboo joint umbrella-shaped building structure. The bending moment distribution of the bamboo-rib umbrella-shaped building structure is larger at the top and smaller at the bottom. The upper part of the structure achieves a larger bending moment through multiple branching columns 13, while the lower part can use columns 11 with a smaller diameter than those in traditional support structures. This allows for a slender column design within a visually perceptible range, while still meeting the bending moment distribution requirements. The main column-top bending moment is borne by the reinforcing ribs 14 located at the top of the branching columns 13, with a smaller portion borne by the resistive couple formed by the reinforcing ribs 14 and the branching columns 13. The vertical force of the bamboo-rib umbrella-shaped building structure is transferred downwards to the lower main structure through the branching columns 13 and the columns 11, solving the vertical support stiffness problem and allowing for a slender column design within a visually perceptible range. Furthermore, large skylights can be installed within the enclosure formed by the branching columns 13 and the reinforcing ribs 14, enabling integrated architectural design and accommodating diverse architectural effects and enhancing transparency. The manufacturing and installation techniques for each component of the bamboo-joint umbrella-shaped building structure are safe, reliable, and highly adaptable.

[0026] In some embodiments, the plurality of branched columns 13 are radially paired and distributed along the upright column 11. The radially paired branched columns 13 improve the overall stiffness of the bamboo-frame umbrella-shaped building structure, resulting in balanced load-bearing capacity, a clear load transmission path, and an aesthetically pleasing appearance. The umbrella-shaped structure formed by the divergent arrangement of the plurality of branched columns 13 evenly distributes the load to the upright column 11, significantly improving wind pressure resistance (capable of withstanding winds of force 10 or higher) and possessing three-dimensional spatial topology optimization capabilities.

[0027] In some embodiments, an elastic deformation space is reserved between adjacent reinforcing ribs 14. The elastic deformation space reserved between the reinforcing ribs 14 absorbs energy through slight deformation under strong winds, avoiding brittle structural failure. Similar to the intelligent response characteristics of "mechanical metamaterials", it realizes the function of dynamic stress adjustment.

[0028] In some embodiments, the extension length L of the branch column 13 is adjustable, and the diameter of the umbrella canopy of the umbrella-shaped structure can be adjusted by adjusting the extension length of the branch column 13. Since each bamboo joint module 12 can be independently assembled and disassembled, and rapid splicing is achieved through standardized interfaces, the extension length of the branch column 13 is adjustable, supporting flexible adjustment of the umbrella canopy diameter of the umbrella-shaped structure, making it suitable for diverse scenarios such as temporary buildings and outdoor sunshades. Specifically, the adjustable range of the umbrella canopy diameter is 3 meters to 15 meters.

[0029] In some embodiments, the splicing angle θ between the forked column 13 and the upright column 11 is adjustable, and the curvature of the umbrella-shaped structure can be adjusted by adjusting the splicing angle. Since each bamboo joint module 12 can be independently assembled and disassembled, and the natural tensile strength of bamboo (up to 60% of that of steel) and flexibility perfectly match the dynamic requirements of the umbrella-shaped structure, the splicing angle between the forked column 13 and the upright column 11 can be adjusted by fully utilizing the original structural and physical properties of bamboo and the prestressing tension of the reinforcing material.

[0030] In some embodiments, a flexible photovoltaic film (not shown) is provided on the bamboo surface of the bamboo joint module 12 to achieve an integrated "structure-energy" design and realize the integration of energy and ecology.

[0031] In some embodiments, the skylight 15 is a glass skylight, which serves both sunshade and light transmission functions.

[0032] In some embodiments, the reinforcing ribs 14 are rods 141 disposed between adjacent bifurcated columns 13, and the rods 141 are arranged longitudinally and transversely to form a multi-level grid. The umbrella-shaped structure formed by the divergent arrangement of multiple bifurcated columns 13 forms a multi-level grid through dense ribs (dense reinforcing ribs formed by longitudinally and transversely arranged rods 141), similar to a "fractal geometry" distribution. This design evenly distributes the load to the columns 11, significantly improving wind pressure resistance (capable of withstanding winds of force 10 or higher) and possessing three-dimensional spatial topology optimization capabilities. Specifically, the rods 141 are made of steel.

[0033] In some embodiments, a lamp 16 is provided on the column 11 to provide lighting. The lamp 16 may be a solar lamp.

[0034] In the above embodiments, the columns of the bamboo-joint umbrella-shaped building structure are formed by multiple supporting rods, which are spliced ​​together from multiple bamboo joint modules. Multiple branched columns 13, also composed of bamboo joint modules, are fixed to the columns and arranged radially from the columns to form an umbrella-shaped structure. Adjacent branched columns are connected by reinforcing ribs to form a grid. Each bamboo joint module can be independently assembled and disassembled. The joints between adjacent bamboo joint modules are connected using mortise and tenon joints or adhesive. Utilizing the original structure and physical properties of bamboo, a high-strength, large-span, low-energy-consumption, environmentally friendly, and approachable building structure is formed. This reduces the technical requirements, production costs, and maintenance costs of building materials, and is a green and environmentally friendly material, combining technological breakthroughs and ecological value. By mimicking the natural joint structure of bamboo and splicing segmented bamboo joint modules, a bamboo-joint biomimetic design is achieved, combining lightweight and high strength. The natural fiber distribution of bamboo joints optimizes mechanical properties, while the use of mortise and tenon joints or bio-adhesive bonding technology at splicing nodes reduces metal connectors and improves overall integrity. At the same time, the natural weather resistance and structural self-stability of bamboo reduce the need for long-term maintenance, effectively lowering maintenance costs. This achieves three-dimensional spatial topology optimization, dynamic stress adjustment, modularity and scalability, energy and ecological integration, architectural aesthetic expression, low-carbon manufacturing process, and low maintenance costs.
