Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a bamboo-joint umbrella-shaped building structure. Background Art

[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, and the architectural styles are becoming increasingly diverse. Existing large-span spatial structures generally use large-span steel structures. Large-span steel structures are generally placed on a concrete or steel support structure through spherical joints. However, reinforced concrete building materials require high production technology, are expensive to produce, and are not environmentally friendly. In addition, large-span steel structures also have high maintenance costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a bamboo-jointed umbrella-shaped building structure, which utilizes the original structure and physical properties of bamboo to form a high-strength, large-span, low-energy-consuming, green and environmentally friendly building structure with a sense of intimacy, thereby reducing the technical requirements, production costs and maintenance costs of building materials. It is also a green and environmentally friendly material, and has both technological breakthroughs and ecological value.

[0004] To achieve the above-mentioned purpose, one embodiment of the present invention provides a bamboo-joint umbrella-shaped building structure, comprising: a column, formed by a plurality of support rods, the column being fixed on a lower main structure or a foundation position, the support rods being formed by splicing a plurality of bamboo-joint modules; a plurality of forked columns, fixed to the column and radially arranged with the column as the center to form an umbrella-shaped structure, the forked columns being formed by splicing a plurality of bamboo-joint modules, and a grid being formed by reinforcing ribs between adjacent forked columns, and a skylight being provided in the grid; wherein each of the bamboo-joint modules can be independently disassembled and assembled, and each of the bamboo-joint modules comprises at least one bamboo joint, and the splicing nodes of two adjacent bamboo-joint modules are connected by mortise and tenon joints or bonded by biological glue.

[0005] According to the above technical solution, the columns of the bamboo-joint umbrella-shaped building structure are formed by enclosing a plurality of support rods, and the support rods are spliced by a plurality of bamboo-joint modules. A plurality of bifurcated columns 13 spliced by a plurality of bamboo-joint modules are fixed to the columns and radially arranged with the columns as the center to form an umbrella-shaped structure. A grid is formed between adjacent bifurcated columns by reinforcing ribs. Each bamboo-joint module can be independently disassembled and assembled. The splicing nodes of two adjacent bamboo-joint modules are connected by mortise and tenon joints or bonded by biological glue. By utilizing the original structure and physical properties of bamboo, a high-strength, large-span, low-energy-consuming, green and environmentally friendly building structure with a sense of intimacy is formed, which reduces the technical requirements, production costs and maintenance costs of building materials. It is a green and environmentally friendly material with both technological breakthroughs and ecological value. By imitating the natural node structure of bamboo and splicing segmented bamboo-joint modules, a bamboo-joint bionic design is realized, achieving a combination of lightweight and high strength. The natural fiber distribution of bamboo nodes optimizes mechanical properties. At the same time, mortise and tenon or bio-glue bonding technology is used at the splicing nodes to reduce metal connectors and improve integrity. At the same time, the natural weather resistance and structural self-stability of bamboo reduce long-term maintenance requirements and effectively lower maintenance costs, achieving three-dimensional spatial topology optimization, dynamic stress regulation, modularity and scalability, energy and ecological integration, architectural aesthetic expression, low-carbon manufacturing process and low maintenance costs.

[0009] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0010] Please also refer to Figures 1 to 3 ,in, Figure 1 A schematic diagram of the structure of a bamboo-jointed umbrella-shaped building structure provided by one embodiment of the present invention; Figure 2 A schematic diagram of a bamboo joint module provided in one embodiment of the present invention; Figure 3 A three-dimensional diagram of a bamboo-jointed umbrella-shaped building structure provided by one embodiment of the present invention.

[0011] like Figures 1 to 3 As shown, the bamboo-joint umbrella-shaped building structure described in this embodiment includes: a column 11 and a plurality of bifurcated columns 13. The column 11 is formed by enclosing a plurality of support rods 111. The column 11 can be fixed on the lower main structure 10 or the base position. The support rods 111 are spliced by a plurality of bamboo-joint modules 12. A plurality of the bifurcated columns 13 are fixed to the column 11 and are radially arranged with the column 11 as the center to form an umbrella-shaped structure. The bifurcated columns 13 are also spliced by a plurality of bamboo-joint modules 12. A grid is formed between adjacent bifurcated columns 13 by reinforcing ribs 14, and a skylight 15 is provided in the grid. Specifically, each of the bamboo-joint modules 12 can be independently disassembled and assembled, and each of the bamboo-joint modules 12 includes at least one bamboo joint. The splicing nodes 121 of two adjacent bamboo-joint modules 12 are connected by mortise and tenon joints or bonded by biological glue.

[0012] In this embodiment, the bottom of the column 11 can adopt a ball joint support, a pin connection or other hinged forms to achieve a fixed connection with the lower main structure or the foundation position.

[0013] Each of the bamboo joint modules 12 can be independently disassembled and assembled, and its modularity and scalability make it suitable for diverse scenarios such as large-span temporary buildings (such as exhibition halls, emergency shelters), ecological landscape facilities (such as park sunshades, bus stop sunshades), etc. The natural texture and joint arrangement of bamboo form a unique oriental aesthetic image, and the structure itself can be used as a public art installation. All of the bifurcated columns 13 are connected together by the reinforcing ribs 14. It should be noted that the diameter and height of the column 11 in this embodiment, the distribution of the bifurcated columns 13, the structure and shape of the reinforcing ribs 14, etc. can all be adaptively selected according to architectural requirements.

[0014] Bamboo, characterized by rapid growth and a short rotation period, is also characterized by high strength, toughness, and hardness, with a dense exterior and sparse interior, offering excellent advantages for biomimetics research. my country leads the world in bamboo species, bamboo forest area, and stock volume, making it one of the richest countries in bamboo resources. Replacing traditional metal or plastic framing with rapidly renewable bamboo, a sustainable material, effectively reduces the carbon footprint. Bamboo's natural tensile strength (up to 60% of steel) and flexibility are perfectly suited to the dynamic demands of umbrella-like structures. By leveraging bamboo's natural structural and physical properties and the prestressed tension of the tie rods, bamboo can be processed into a high-strength, long-span, low-energy, environmentally friendly, and user-friendly structural material. This can effectively alleviate the supply and demand imbalance of concrete and steel, offering broad development and application prospects. By mimicking bamboo's natural nodular structure and joining segmented bamboo joint modules, a biomimetic bamboo design is achieved, combining lightweight construction with high strength. The natural fiber distribution of bamboo nodes optimizes mechanical properties. At the same time, mortise and tenon or bio-glue bonding technology is used at the splicing nodes to reduce metal connectors and improve integrity. At the same time, the natural weather resistance and structural self-stability of bamboo reduce long-term maintenance needs and effectively reduce maintenance costs.

[0015] In some embodiments, the bamboo joint modules 12 are constructed from raw bamboo that has undergone high-temperature carbonization. Raw bamboo refers to bamboo with a naturally knotted structure. The hollow raw bamboo is carbonized and then composited into the bamboo joint modules. The high-temperature carbonization of the raw bamboo provides moth-proofing and anti-corrosion properties, eliminating the need for chemical coatings. Furthermore, the structure is fully biodegradable or recyclable upon scrapping, meeting low-carbon manufacturing requirements.

[0016] In this embodiment, a plurality of the support rods 111 are combined to form the cylindrical column 11, and the diameter of the column 11 gradually increases from bottom to top. That is, the cross-section of the column 11 can be in the form of a uniform cross-section or a cross-section that gradually decreases from top to bottom. Since each bamboo joint module 12 can be independently disassembled and assembled, and the natural tensile strength and flexibility of bamboo (up to 60% of steel) perfectly adapt to the dynamic requirements of the umbrella-shaped structure, by making full use of the original structure and physical properties of bamboo and the prestressed tension of the tie rod material, partial bending of the support rod 111 can be achieved, so that the diameter of the column 11 gradually increases from bottom to top. A plurality of bifurcated columns 13 gradually open outward from the top of the column 11 to form an umbrella-shaped structure, and the plurality of bifurcated columns 13 are connected as a whole by reinforcing ribs 14, thereby forming a bamboo joint-type umbrella-shaped building structure. The bending moment diagram of the bamboo-jointed umbrella-shaped building structure is distributed as large at the top and small at the bottom. The upper end of the bamboo-jointed umbrella-shaped building structure achieves a larger bending moment through the multiple forked columns 13 that are spread out. The lower end of the bamboo-jointed umbrella-shaped building structure can adopt a column 11 with a smaller diameter than the column body of the traditional supporting structure. Therefore, on the basis of meeting the distribution of the bending moment diagram, the column body can be made thinner within a range that can be intuitively felt. The main column top bending moment of the bamboo-jointed umbrella-shaped building structure is borne by the reinforcing ribs 14 set at the top of the forked columns 13, and another small part of the bending moment can be borne by the resisting force couple formed by the reinforcing ribs 14 and the forked columns 13. The vertical force of the bamboo-jointed umbrella-shaped building structure is transmitted downward to the lower main structure through the forked columns 13 and the columns 11, solving the problem of vertical support stiffness and achieving a thinner column body within a range that can be intuitively felt. At the same time, a large-area skylight can be set within the enclosed area formed by the forked columns 13 and the reinforcing ribs 14, which can achieve an integrated expression of the building structure and adapt to the diversity and transparency of the building effects. The manufacturing and installation technologies of the components of the bamboo-jointed umbrella-shaped building structure are safe, reliable and highly adaptable.

[0017] In some embodiments, the multiple bifurcated columns 13 are arranged in pairs radially relative to the upright columns 11. These radially paired bifurcated columns 13 enhance the overall rigidity of the bamboo-jointed umbrella-shaped building structure, resulting in a balanced load-bearing capacity, a clear load transmission path, and an aesthetically pleasing design. The divergent arrangement of the multiple bifurcated columns 13 forms an umbrella-like structure that evenly distributes load across the upright columns 11, significantly improving wind resistance (capable of withstanding winds exceeding force 10) and enabling three-dimensional spatial topology optimization.

[0018] In some embodiments, elastic deformation spaces are reserved between adjacent ribs 14. The elastic deformation spaces between the ribs 14 absorb energy through slight deformation in strong winds, preventing brittle structural failure. This, similar to the intelligent response characteristics of "mechanical metamaterials," enables dynamic stress regulation.

[0019] In some embodiments, the extension length L of the bifurcated column 13 is adjustable, and by adjusting the extension length of the bifurcated column 13, the diameter of the umbrella structure's canopy can be adjusted. Because each bamboo joint module 12 can be independently assembled and disassembled, and quickly spliced together through standardized interfaces, the extension length of the bifurcated column 13 is adjustable, allowing for flexible adjustment of the umbrella structure's canopy diameter, making it suitable for a variety of scenarios such as temporary buildings and outdoor sunshades. Specifically, the canopy diameter can be adjusted within a range of 3 meters to 15 meters.

[0020] In some embodiments, the splicing angle θ between the bifurcated column 13 and the upright column 11 is adjustable. Adjusting this splicing angle can adjust the curvature of the umbrella structure's canopy. Because each bamboo joint module 12 can be independently assembled and disassembled, and bamboo's natural tensile strength (up to 60% of steel) and flexibility perfectly match the dynamic requirements of an umbrella structure, the splicing angle between the bifurcated column 13 and the upright column 11 can be adjusted by fully utilizing the original structural and physical properties of bamboo and the prestressed tension of the tie rod material.

[0021] In some embodiments, a flexible photovoltaic film (not shown) is provided on the bamboo surface of the bamboo joint module 12 to realize an integrated "structure-energy" design and achieve the integration of energy and ecology.

[0022] In some embodiments, the skylight 15 is a glass skylight that has both sunshade and light transmission functions.

[0023] In some embodiments, the reinforcing ribs 14 are rods 141 disposed between adjacent bifurcated columns 13. These rods 141 are arranged vertically and horizontally to form a multi-level grid. The umbrella-like structure formed by the divergent arrangement of multiple bifurcated columns 13 utilizes dense ribs (the dense reinforcement formed by the rods 141 arranged vertically and horizontally) to form a multi-level grid, similar to a "fractal geometry" distribution. This design evenly distributes the load across the columns 11, significantly improving wind pressure resistance (capable of withstanding winds exceeding force 10) and enabling three-dimensional topological optimization. Specifically, the rods 141 are made of steel.

[0024] In some embodiments, a lamp 16 is provided on the column 11 to realize the lighting function. The lamp 16 can be a solar lamp.

[0025] In the above embodiments, the columns of the bamboo-joint umbrella-shaped building structure are formed by enclosing a plurality of support rods, and the support rods are spliced by a plurality of bamboo-joint modules. A plurality of bifurcated columns 13 spliced by a plurality of bamboo-joint modules are fixed to the columns and radially arranged with the columns as the center to form an umbrella-shaped structure. A grid is formed between adjacent bifurcated columns by reinforcing ribs. Each bamboo-joint module can be independently disassembled and assembled. The splicing nodes of two adjacent bamboo-joint modules are connected by mortise and tenon joints or bonded by biological glue. By utilizing the original structure and physical properties of bamboo, a high-strength, large-span, low-energy-consuming, green and environmentally friendly building structure with a sense of intimacy is formed, which reduces the technical requirements, production costs and maintenance costs of building materials. It is a green and environmentally friendly material with both technological breakthroughs and ecological value. By imitating the natural node structure of bamboo and splicing segmented bamboo-joint modules, a bamboo-joint bionic design is realized, achieving a combination of lightweight and high strength. The natural fiber distribution of bamboo nodes optimizes mechanical properties. At the same time, mortise and tenon or bio-glue bonding technology is used at the splicing nodes to reduce metal connectors and improve integrity. At the same time, the natural weather resistance and structural self-stability of bamboo reduce long-term maintenance requirements and effectively lower maintenance costs, achieving three-dimensional spatial topology optimization, dynamic stress regulation, modularity and scalability, energy and ecological integration, architectural aesthetic expression, low-carbon manufacturing process and low maintenance costs.
