Description

Technical Field

[0001] The present invention relates to the technical field of modular building structures, in particular to a landscape structure based on Fuller spheres. Background Art

[0002] In contemporary landscape design, the integration of innovation, environmental protection, and artistic expression has become a key development direction. Currently, common landscape installations on the market (such as sculptures and decorative spheres) primarily utilize fixed structures, which often suffer from issues such as excessive transportation volume, complex on-site assembly, and high costs.

[0003] In existing technologies, landscape installations often use traditional building materials such as metal, stone, or solid wood. These materials are not only expensive but also have significant shortcomings in terms of environmental performance and creative expression. Although some studies have attempted to use environmentally friendly materials (such as bamboo and recycled plastic) as alternatives, they still have significant deficiencies in geometric adaptability, mechanical properties, and artistic expression. Due to its unique geometric aesthetics and excellent mechanical properties, the Fuller sphere structure has garnered widespread attention in the fields of architecture and art in recent years. Its design concept is based on "creating the maximum space with the least amount of material" and is widely used in landscape, exhibition, residential, and public buildings.

[0004] Chinese patent CN106592844A discloses a hemispherical lattice shell assembled house, comprising a horizontal base plate and a hemispherical house body mounted on the base plate. The hemispherical house body is composed of a number of adjacent triangular pyramid boxes, which are connected by base mounting plates, node mounting plates, and limit bolts. The house adopts a modular design and is assembled using standard parts such as node mounting plates. The structure is simple and convenient for manual disassembly and assembly. Chinese patent CN113914471A discloses a spherical tensegrity structure with 24 large rhombus truncated cubes whose surfaces are alternately spliced ​​with square, hexagonal, and octagonal planes. The large rhombus truncated cube tensegrity structure has 48 nodes, located at the 48 vertices of the large rhombus truncated cube, and is composed of internal compression rods and external cables. This solves the problem that existing spherical tensegrity structures with 24 compression rods connected by cables and whose outer surfaces are square, hexagonal, and octagonal planes have not yet been found. Chinese patent CN114575461A discloses a modular, nested annular tensegrity structure, comprising an outer ring tensegrity unit, an inner ring tensegrity unit, and a connecting assembly. The connecting assembly connects the outer and inner ring tensegrity units to form a nested annular tensegrity structure with a paraboloid and adjustable curvature. The outer and inner ring tensegrity units share the same topology, identical centers, and proportional lengths of similar components. Through modular assembly, the present invention provides a novel annular tensegrity structure with a unique configuration, featuring a paraboloid and adjustable curvature, enriching the connection options for annular tensegrity structures.

[0005] However, all of the above existing technologies are structural improvements, and none have combined the Fuller ball structure with straws, a lightweight, environmentally friendly material, for practical landscape design. This remains an innovative endeavor within the industry. Therefore, developing straw-based Fuller ball landscape installations has significant technical value and market significance: on the one hand, it can meet the growing demand for environmentally friendly design, and on the other hand, it can provide a new form of expression and technical path for landscape art creation, effectively resolving the technical contradictions between traditional installations in terms of environmental protection, disassembly, and artistic expression. Summary of the Invention

[0006] The present invention provides a Fuller sphere landscape structure, which innovatively uses straws to make the landscape structure. It aims to provide a new solution for modern landscape design through the organic combination of lightweight and environmentally friendly materials and advanced geometric structures.

[0007] The structure of the present invention cleverly utilizes the lightweight, easy processability and environmental advantages of straws, combined with the geometric stability of the Fuller sphere structure, to create a landscape device that combines artistic beauty, environmental characteristics and practical functions, greatly enriching the expression and connotation of landscape design.

[0008] The technical solutions of the present invention are as follows:

[0009] A Fuller sphere landscape structure comprises a supporting base, hollow components, polyhedron connection nodes, grounding nodes, and door connection nodes.

[0010] The support base is located at the bottom of the Fuller sphere landscape structure; the hollow component is a hollow cylindrical structure, which constructs a regular hexagonal unit structure; the two ends of the hollow component are connected to the polyhedron connection nodes, and the inner and outer layers of the hollow components are connected through the polyhedron connection nodes; each polyhedron connection node is provided with a multi-directional interface, and each interface of the multi-directional interface is provided with an insert; the connection angle of the hollow component is consistent with the insert angle of the polyhedron connection node; the grounding node is fixedly connected to the support base, and the support base and the Fuller sphere structure thereon are connected through the grounding node; an opening that meets the needs of human passage is formed in the structure through the door connection node.

[0011] The support base is located at the bottom of the Fuller sphere landscape structure and plays a supporting role. It includes wooden boards, wooden planks, L-shaped angle steels, and bolts. Two wooden planks are located at the bottom of the support base and are divided into inner and outer circles to fit the grounding node. Two circles of L-shaped angle steels are installed back to back between the two wooden planks. Wooden boards are covered on the angle steels and wooden planks. Bolts are passed through the wooden planks to fix the grounding node and establish a flexible connection with the ground.

[0012] The hollow component is a hollow cylindrical structure, preferably a straw structure. The two ends of the hollow component are connected to the polyhedron connection nodes. The length of the hollow component is determined by precise geometric calculation to construct a regular hexagonal unit structure. If the length of the hollow component of the inner facade of the hexagonal unit is A, the length of the hollow component of the outer facade hexagon is The length of the web connecting the inner and outer hexagonal faces through the node is The connection angle of the hollow component is consistent with the angle of the insert of the polyhedron connection node.

[0013] The polyhedral connection node includes twelve regular channels, seven boundary channels, eight intersection channels (one), ten intersection channels, six regular channels, five boundary channels, seven intersection channels, and eight intersection channels (two); a multi-directional interface is provided on each polyhedral connection node, and an insert is provided on each interface of the multi-directional interface; each insert is provided with a circular ring-shaped protrusion structure on the outside, wherein the circular ring-shaped protrusion structure is 15 mm away from the top of the interface, and the ends of the hollow components are fixedly connected, and the preferred connection method is sleeve connection, and preferably the tail end of the hollow component is in close contact with the circular ring-shaped protrusion structure in the insert to form a tight friction fixation, thereby achieving a dynamic balance between rapid assembly and structural stability.

[0014] The inner and outer hollow components are connected via polyhedral connection nodes, and a stable and reliable connection is achieved through frictional engagement between the inner wall of the hollow component and the outer wall of the polyhedral connection node insert.

[0015] The Fuller sphere landscape structure has a total of 10 regular hexagonal units (including 5 upper hexagonal units, 5 lower hexagonal units), 4 half-hexagonal units, and 6 regular pentagonal cavity units (including the entrance cavity unit).

[0016] Set the space angle (dihedral angle) between regular hexagonal units to β,

[0017] but

[0018] Set the space angle (dihedral angle) between the regular pentagonal unit and the regular hexagonal unit to θ,

[0019] but

[0020] Assume that the side length of the small hexagon inside the regular hexagonal unit is A; then the side length of the outer triangle is The perpendicular distance between the inner hexagonal plane and the outer hexagonal plane is β, and The dimension of the web is E, and

[0021] Set the spatial angle between the web and the inner and outer hexagonal planes to α,

[0022] but but

[0023] In the isosceles triangle formed by the two webs and the side length of the inner hexagon, the lengths of the three sides are E, E, and A respectively. Let the vertex angle be γ1 (to the base A) and the base angle be γ2 (to the equal side E), then

[0024]

[0025] Then, the interior angles of the isosceles triangle are γ1~35.26° and γ2~72.37°.

[0026] The lengths of the three sides of the isosceles triangle formed by the two webs and the sides of the outer triangle are E, E, Let the vertex angle be γ3 (to the base ), the base angle is γ4 (equilateral side E), then

[0027]

[0028] Then, the interior angles of the isosceles triangle are γ3~63.43° and γ4~58.28°.

[0029] The original standard component for polyhedral connection nodes, grounding nodes, and door connection nodes is the regular twelve-hole. The regular twelve-hole is located at standard locations on the exterior facade of the hexagonal unit (excluding intersections and boundary nodes). Along with the regular six-hole, it is the most commonly used node type in the entire Fuller sphere landscape structure. The regular twelve-hole contains 12 inserts, whose central axes, extended inversely, intersect at a single point, forming a center point. The central axes of six of these inserts lie in the same horizontal plane passing through this center point, with their projections on the outer plane forming an angle of 60°. The central axes of the remaining six inserts form spatial angles with the horizontal plane ranging from α to 52.65°. The vertex angles between oblique inserts and horizontal inserts range from γ4 to 58.28°. Both horizontal and oblique inserts can be replicated by rotating them 60° around the center point. The vertex angles between adjacent inserts range from γ1 to 35.26°.

[0030] The seven boundary joints are located at the top and two side edges of the hexagonal facade and feature seven inserts. Four of these inserts are located horizontally (center left, lower left, center right, and lower right). (All orientations are based on the node's installation position within the inner and outer hexagonal planes of the landscape structure). The angle between the central axes of two adjacent horizontal inserts is 60°. The remaining three are diagonal inserts. The seven boundary joints are formed by subtracting the upper five inserts from the regular twelve joints, including two horizontal inserts and three diagonal inserts.

[0031] The intersection eight-way (1) is located at the vertex position where the hexagonal unit and the adjacent unit (including hexagonal unit and semi-hexagonal unit) meet on the facade. It is equipped with 8 inserts, of which the 5 inserts located on the facade are divided into two groups: one group of two (left center and lower left positions) and the other group of three (upper right, right center and lower right positions). The angle between the central axes of adjacent inserts in each group is 60°, and the spatial angle between the planes where the two groups of inserts are located is The spatial angles between the remaining three inserts (located at the lower left, upper right, and lower right positions) and the adjacent facade inserts are γ4 to 58.28°.

[0032] The intersecting ten-way connection is located at other locations where the exterior facades of the hexagonal unit intersect with adjacent units (including hexagonal units and semi-hexagonal units) (i.e., diagonally below the intersecting eight-way connection (1)). It is equipped with 10 inserts. The intersecting ten-way connection is formed by adding two inserts to the intersecting eight-way connection (1). One of the inserts is located on the exterior facade, forming two groups of three inserts in this direction; the other is located on the upper left side of the interior, and its vertex spatial angle with the adjacent insert (hexagonal unit exterior facade) is γ4 to 58.28°.

[0033] The regular hexagonal joint is located in the middle of the inner facade of the hexagon (including semi-hexagonal units) and is equipped with 6 inserts, 3 of which are used to connect the 3 webs, and the other 3 are used to connect the 3 hollow components of the inner facade. The 3 inserts used to connect the hollow components of the inner facade are coplanar, and the angle between the central axes of the inserts is 120°. The vertex space angle between the insert used to connect the web and the adjacent insert connected to the hollow component of the inner facade is γ2~72.37°. The orthographic projection line of the insert used to connect the web on the inner facade is 60° to the plane of the hollow component, and the vertex space angle between two adjacent inserts is γ3~63.43°.

[0034] The boundary bottom bracket has five inserts located at the top and lower sides of the upper hexagonal unit's interior elevation, the bottom and upper sides of the lower hexagonal unit's interior elevation, and the top and bottom of the semi-hexagonal unit. The boundary bottom bracket is a regular bottom bracket with one insert removed, extending outward from the inner hexagonal plane.

[0035] The second intersection of eight channels is located at the junction of the upper and lower hexagonal units (excluding the seventh intersection channel), and has a total of eight inserts. The second intersection of eight channels is achieved by rotating the two boundary five channels 180 degrees vertically from the center point and removing the two overlapping inserts.

[0036] The seven-way junction is located on both sides of the bottom of the inner facade of the lower hexagonal unit and is equipped with 7 inserts. The seven-way junction is achieved by removing one insert (i.e., the lower position of the eight-way junction (II)) based on the eight-way junction (II).

[0037] The base is set on the grounding node, and the bottom surface of the base is tightly fitted with the wooden board on the top surface of the support base to increase the contact area. The support base and the Fuller sphere structure on it are connected through the grounding node to enhance structural stability.

[0038] The grounding nodes include grounding node (1), grounding node (2), grounding node (3), and grounding node (4), wherein 5 plug-ins are provided on grounding node (1), and 6 plug-ins are provided on grounding node (2), grounding node (3), and grounding node (4), and each plug-in is provided with a circular protrusion structure on the outside, which is fixedly connected to the end of the hollow component.

[0039] Grounding nodes (1) and (2) are formed by removing the downward-facing insert at the bottom of the cross-connection, and adding a base at the bottom, which is connected to the lower support base via bolts. Grounding node (1), as the entrance node, also removes the insert extending outward on the right side.

[0040] Grounding nodes (3) and (4) are implemented by removing the downward-facing insert from the regular twelve-way structure. Grounding node (4) is located at the bottom of the semi-hexagonal unit, while grounding node (3) is located at the bottom of the lower hexagonal unit. The only difference between the two is the orientation of the hollow component they connect (which remains consistent with the orientation of the facade units).

[0041] Grounding nodes (1) and (2) are used at corners, and the contact surface between their bases and the upper wooden board of the support base is an irregular hexagon. The contact surface between the bases of grounding nodes (3) and (4) and the upper wooden board of the support base is a regular quadrilateral.

[0042] The door connection nodes, including three-way, six-way, and seven-way doors, are configured with three, six, and seven inserts, respectively. The three-way door is created by removing the three inserts on the right side of the six-way door, the six-way door is created by removing the insert at the lower right side of the seven-way door, and the seven-way door is created by removing the insert at the lower right side of the eight-way door (two). Through the configuration of the door connection nodes, an opening is formed in the structure that meets the needs of human passage.

[0043] Preferably, the support base is made of solid wood and / or metal material, and can be customized in different specifications and forms according to the actual application scenario requirements; the surface of the solid wood is treated with preservative impregnation, and the surface of the metal is treated with galvanizing for rust prevention.

[0044] Preferably, the support base adopts a modular composite structure design, and its construction system is composed of a bottom load-bearing unit and an intelligent adjustment system.

[0045] The bottom load-bearing unit is constructed from two parallel welded 50×50mm standard anti-corrosion wood planks, forming a dual-bending load-bearing system. An innovative bidirectional symmetrical support structure is incorporated: two L-shaped steel angle reinforcement rings mounted in opposite directions. The angle lengths are precisely calculated to match the cross-section of the wood planks, creating a 1:1 ratio, creating a three-dimensional support network. The wooden planks are bolted to the ground via grounding nodes, providing a flexible connection to the ground. The top protective layer is made of 20mm thickened anti-corrosion wood planks treated with CCA's environmentally friendly anti-corrosion process. The intelligent adjustment system is primarily implemented using bolts. These M12 stainless steel adjustment bolts offer three innovative functions: an open-bottom contact design allows the base of the bolt to extend beyond the wood planks and rest directly on the ground. This creates a continuous airflow layer of ≥5mm between the exposed bolt base and the ground, providing natural moisture-proofing and drainage. A built-in precision thread adjustment mechanism supports ±30mm vertical travel adjustment, adapting to varying terrain elevation differences. Anti-settling pressure washers and a self-locking nut assembly ensure structural stability after adjustment.

[0046] As a preference, the length of the hollow component is 133-230 mm (the length is adjustable, the length of the hollow component of the inner facade of the hexagonal unit is A, and the length of the hollow component of the outer facade is The length of the web connecting the inner and outer hexagonal faces through the node is

[0047]

[0048] The preferred outer diameter is 5-15mm, with a wall thickness range of 0.3mm-1.2mm; the preferred outer diameter is 9-11mm, with a wall thickness range of 0.5mm-1mm; and the preferred outer diameter is 10mm, with a wall thickness range of 0.8mm. Under standardized manufacturing, the 10mm outer diameter is 98% compatible with current punching dies for beverage packaging sealing films (ASTM F963 compatibility testing) and meets the economical production requirements of industrial injection mold tolerances (ISO 2768-class M).

[0049] Preferably, the hollow component can be a straw made of environmentally friendly and degradable materials, preferably polylactic acid (PLA) or polyhydroxyalkanoate (PHA) materials, and more preferably a straw made of polylactic acid (PLA).

[0050] Preferably, the polyhedron connection nodes, grounding nodes, and gate connection nodes are all resin connectors manufactured using 3D printing technology.

[0051] Preferably, the multi-directional interfaces of the polyhedral connection nodes are designed with standardized annular interfaces of different spatial angles. The slot depth and width of each interface are precisely matched with the outer diameter of the straw, and the dimensional tolerance is controlled within the range of ±1mm.

[0052] Preferably, the grounding node and the support base are fixed with standardized bolts.

[0053] Preferably, the entire system of the present invention achieves a three-dimensional balance of structural strength, environmental weather resistance and construction adaptability through a combination of standardized components, and is particularly suitable for the long-term support needs of complex sites such as garden landscapes and outdoor facilities.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] The use of recyclable straws as the primary building material not only aligns with current sustainable development and environmental protection concepts, but also, through the unique geometric structure of the Fuller sphere, creates an artistic form with a distinctly modern and technological feel. This innovative combination injects a new visual language and design element into the landscape design field, breaking through the aesthetic limitations of traditional landscape installations.

[0056] The structural system designed based on the Fuller sphere geometry principle has natural mechanical advantages, can withstand certain wind forces and external force impacts, and can maintain good structural stability in various complex outdoor environments.

[0057] The standardized straw components and polyhedral connection node design enable efficient modular construction, improving on-site installation efficiency, reducing transportation volume, and lowering maintenance costs. This modular design enables the device to be quickly assembled and easily disassembled, significantly reducing construction difficulty and overall costs, and providing a new solution for the implementation of landscape projects.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0092] Embodiment 1:

[0093] Reference Figures 1 to 28 As shown, a Fuller sphere landscape structure includes a support base 1, a hollow component 2, a polyhedron connection node 3, a grounding node 4, and a door connection node 5.

[0094] The support base 1 is located at the bottom of the Fuller sphere landscape structure; the hollow component 2 is a hollow cylindrical structure, which constructs a regular hexagonal unit structure; the two ends of the hollow component 2 are connected to the polyhedron connection node 3, and the upper and lower hollow components 2 are connected through the polyhedron connection node 3; each polyhedron connection node 3 is provided with a multi-directional interface, and each interface of the multi-directional interface is provided with an insert; the connection angle of the hollow component 2 is consistent with the insert angle of the polyhedron connection node 3; the grounding node 4 is fixedly connected to the support base 1, and the support base 1 and the Fuller sphere structure thereon are connected through the grounding node 4; an opening that meets the needs of human passage is formed in the structure through the door connection node 5.

[0095] The support base 1 is located at the bottom of the Fuller sphere landscape structure and plays a supporting role. It includes a wooden board 101, a wooden board 102, an L-shaped angle steel 103, and a bolt 104. Two wooden boards 102 are located at the bottom of the support base 1 and are divided into two inner and outer circles to fit the grounding node 4. Two circles of L-shaped angle steel 103 are installed back to back between the two wooden boards 102. Wooden boards 101 are covered on the angle steel 103 and the wooden boards 102. The grounding node 4 is fixed through the wooden boards by bolts 104 to establish a flexible connection with the ground.

[0096] The hollow component 2 is a straw structure, and the two ends of the hollow component 2 are connected to the polyhedron connection nodes 3 to construct a regular hexagonal unit structure. The length of the hollow component 2 on the inner facade of the hexagonal unit is A (A = 200mm), and the length of the hollow component 2 on the outer facade is The length of the web connecting the inner and outer hexagonal faces through the node is The connection angle of the hollow component 2 is consistent with the angle of the insert 6 of the polyhedron connection node 3.

[0097] The polyhedral connection node 3 includes twelve regular channels 301, seven boundary channels 302, eight intersection channels (one) 303, ten intersection channels 304, six regular channels 305, five boundary channels 306, seven intersection channels 307, and eight intersection channels (two) 308; a multi-directional interface is provided on each polyhedral connection node 3, and an insert 6 is provided on each interface of the multi-directional interface; each insert 6 is provided with a circular ring-shaped protrusion structure 7 on the outside, wherein the circular ring-shaped protrusion structure 7 is 15 mm away from the top of the interface and is sleeved with the end of the hollow component 2, and the tail end of the hollow component 2 is in close contact with the circular ring-shaped protrusion structure 7 in the insert 6, forming a friction fixation, thereby achieving a dynamic balance between rapid assembly and structural stability.

[0098] The upper and lower hollow components 2 are connected via the polyhedron connection node 3 , and the connection is firm and reliable through frictional engagement between the inner wall of the hollow component 2 and the outer wall of the insert 6 of the polyhedron connection node 3 .

[0099] The original standard components for the polyhedron connection node 3, the grounding node 4, and the door connection node 5 are all regular twelve-hole nodes 301. Regular twelve-hole nodes 301 are located in standard locations on the hexagonal unit facade (excluding intersection nodes and boundary nodes). Along with regular six-hole nodes 305, they are the most commonly used node type in the entire Fuller sphere landscape structure. Regular twelve-hole nodes 301 contain 12 inserts 6, whose central axis extensions converge at a single point, forming a center point. The central axes of six of these inserts 6 lie in the same horizontal plane passing through this center point, and their projections on the outer plane form an angle of 60°. The central axes of the remaining six inserts form a spatial angle of 52.65° with the horizontal plane. The vertex spatial angle between the oblique inserts and the horizontal inserts is 58.28°. Both horizontal inserts and oblique inserts can be replicated by rotating 60° around the center point. The vertex spatial angle between two adjacent inserts is 35.26°.

[0100] The seven boundary joints 302 are located at the top and two side edges of the hexagonal facade and are equipped with seven inserts 6, four of which are located in the horizontal plane (center left, lower left, center right, and lower right). (All orientation descriptions are based on the node's installation position within the inner and outer hexagonal planes of the landscape structure). The angle between the center axes of two adjacent horizontal inserts 6 is 60°, and the other three are diagonal inserts. The seven boundary joints 302 are formed by subtracting the upper five inserts from the regular twelve joints 301, minus the two horizontal inserts and the three diagonal inserts.

[0101] The intersection eight-way (1) 303 is located at the vertex position where the facade of the hexagonal unit intersects with the adjacent unit (including the hexagonal unit and the semi-hexagonal unit), and is provided with 8 inserts 6, of which the 5 inserts 6 located in the facade direction are divided into two groups: one group of 2 (left middle and lower left positions), and the other group of 3 (upper right, right middle and lower right positions). The angle between the central axes of adjacent inserts 6 in each group is 60°, and the spatial angle between the planes where the two groups of inserts 6 are located is 138.19°; the spatial angle between the remaining 3 inserts (located at the lower left, upper right and lower right positions) and the adjacent facade inserts is about 58.28°.

[0102] Intersection cross-connection 304 is located at another location where the exterior facades of the hexagonal unit intersect with adjacent units (including hexagonal units and semi-hexagonal units) (i.e., diagonally below intersection cross-connection (I)). It is equipped with ten inserts 6. Intersection cross-connection 304 is formed by adding two inserts to intersection cross-connection (I) 303. One of these inserts is located on the exterior facade, forming two groups of three inserts 6 each. The other is located on the inner left side, forming a spatial angle of approximately 58.28° with the vertex of the adjacent insert 6 (on the exterior facade of the hexagonal unit).

[0103] The regular six-way joint 305 is located in the middle of the inner facade of the hexagon (including semi-hexagonal units) and is equipped with six inserts 6, three of which are used to connect the three web members, and the other three inserts 6 are used to connect the three hollow components 2 of the inner facade. The three inserts 6 used to connect the inner facade hollow components 2 are coplanar, and the angle between the center axes of the inserts 6 is 120°. The vertex spatial angle between the insert 6 used to connect the web members and the adjacent insert 6 connected to the inner facade hollow component 2 is 72.37°. The orthographic projection line of the insert 6 used to connect the web members on the inner facade is at a 60° angle to the plane of the hollow component 2, and the vertex spatial angle between two adjacent inserts is 63.43°.

[0104] Boundary bottom bracket 306 is located at the top and lower sides of the upper hexagonal unit's inner facade, at the bottom and upper sides of the lower hexagonal unit's inner facade, and at the top and bottom of the semi-hexagonal unit. It has five inserts 6. Boundary bottom bracket 306 is formed by removing an insert that connects to the inner hexagonal plane and extends outward.

[0105] The intersecting eight-way (two) 308 is located at the connection part of the inner facade of the upper and lower hexagonal units (excluding the intersecting seven-way 307), with a total of 8 inserts 6. The intersecting eight-way (two) 308 is realized by rotating the two boundary five-way 306 180 degrees vertically from the center point and removing the two overlapping inserts.

[0106] The seven-way junction 307 is located at the bottom both sides of the facade of the lower hexagonal unit and is provided with seven insert tubes 6. The seven-way junction 307 is realized by deleting one insert tube 6 (i.e. the lower position of the eight-way junction (two) 308) on the basis of the eight-way junction (two).

[0107] The base 8 is provided on the grounding node 4, and the bottom surface of the base 8 is closely fitted with the wooden board 101 on the top surface of the support base 1 to increase the contact area. The support base 1 and the Fuller sphere structure thereon are connected through the grounding node 4 to enhance the structural stability.

[0108] The grounding node 4 includes a grounding node (1) 401, a grounding node (2) 402, a grounding node (3) 403, and a grounding node (4) 404, wherein five plug-ins 6 are provided on the grounding node (1) 401, and six plug-ins 6 are provided on the grounding node (2) 402, the grounding node (3) 403, and the grounding node (4) 404. Each plug-in is provided with a circular protrusion structure 7 on the outside, which is fixedly connected to the end of the hollow component 2.

[0109] Grounding node (1) 401 and grounding node (2) 402 are formed by removing the downward-facing insert at the bottom of the intersection crossbar 304 and adding a base 8 at the bottom. They are connected to the lower support base 1 via bolts 104. Grounding node (1) 401, as the entrance node, also removes the insert 6 extending outward on the right side.

[0110] Grounding node (3) 403 and grounding node (4) 404 are implemented by removing the downward-facing insert 6 from the regular twelve-way structure. Grounding node (4) 404 is located at the bottom of the semi-hexagonal unit, while grounding node (3) 403 is located at the bottom of the lower hexagonal unit. The only difference between the two is the spatial orientation of the part connecting the hollow component 2 (the orientation in this case remains consistent with the orientation of the facade unit).

[0111] Grounding nodes (1) 401 and (2) 402 are used at corners, and the contact surface between their bases 8 and the upper wooden board of the support base 1 is an irregular hexagon. The contact surface between their bases 8 and the upper wooden board of the support base 1 is a regular quadrilateral at grounding nodes (3) 403 and (4) 404.

[0112] The door connection nodes 5 include a three-way door 501, a six-way door 502, and a seven-way door 503, each equipped with three, six, and seven inserts, respectively. The three-way door 501 is created by removing the three inserts 6 on the right side of the six-way door 305. The six-way door 502 is created by removing the insert 6 at the lower right side of the seven-way door 307. The seven-way door 503 is created by removing the insert 6 at the lower right side of the eight-way door (two) 308. The arrangement of the door connection nodes 5 creates an opening in the structure that meets the needs of human passage.

[0113] The spatial angle (dihedral angle) between the lower hexagonal unit and the side semi-hexagonal unit is 138.19°; the spatial angle (dihedral angle) between the upper and lower regular hexagons and the regular hexagon is 138.19°.

[0114] The support base 1 is made of solid wood / metal material; the surface of the solid wood is treated by impregnation with an antiseptic, and the surface of the metal is treated by galvanizing for rust prevention.

[0115] The supporting base 1 adopts a modular composite structure design, and its structural system is composed of a bottom load-bearing unit and an intelligent adjustment system.

[0116] The bottom load-bearing unit utilizes two parallel welded 50×50mm standard anticorrosive wood planks 102, forming a dual-bending load-bearing system. This innovative bidirectional symmetrical support structure features two rings of back-to-back L-shaped angle steel 103 reinforcement rings. The angle steel limb lengths are precisely calculated to create a 1:1 ratio with the wood plank cross-section, creating a three-dimensional support network. Wood planks 101 are fixed to grounding nodes 4 via bolts 104, establishing a flexible connection to the ground. The top protective layer of wood planks 101 utilizes 20mm thickened anticorrosive wood planks treated with the CCA environmentally friendly anticorrosive process. The intelligent adjustment system is primarily implemented via bolts 104. Bolt 104 is an M12 stainless steel adjustment bolt. The bolt 104 system has three functional innovations: it adopts a bottom open contact design, and the bottom of the bolt 104 extends beyond the wooden board and falls directly to the ground. A continuous air circulation layer of ≥5mm is formed between the exposed bottom of the bolt 104 and the ground, realizing natural moisture-proof and drainage; the built-in precision thread adjustment mechanism supports ±30mm vertical stroke adjustment, which can adapt to various terrain height differences; combined with anti-settlement pressure gaskets and self-locking nut groups, it ensures the stability of the structure after adjustment.

[0117] The hollow component 2 is a straw made of polylactic acid (PLA), with an outer diameter of 10 mm and a wall thickness of 0.8 mm.

[0118] The polyhedron connection node 3, the grounding node 4, and the gate connection node 5 are all resin connectors manufactured using 3D printing technology.

[0119] The multi-directional interfaces of the polyhedral connection nodes 3 are designed with standardized annular interfaces at different spatial angles. The slot depth and width of each interface are precisely matched with the outer diameter of the straw, and the dimensional tolerance is controlled within the range of ±1mm.

[0120] The grounding node 4 is fixed to the supporting base 1 by using standardized bolts.

[0121] The entire system of the present invention achieves a three-dimensional balance of structural strength, environmental weather resistance and construction adaptability through a combination of standardized components. It is particularly suitable for the long-term support needs of complex sites such as garden landscapes and outdoor facilities.

[0122] The Fullerite straw landscape structure of the present invention utilizes an innovative modular geometric design. The upper structure comprises five complete regular hexagonal units, while the lower structure also features five regular hexagonal units, with four additional, precisely calculated, semi-hexagonal transition units. By adjusting the size of the hollow component 2, various configurations, both large and small, can be achieved.

[0123] The structural units of the present invention are securely connected via specially designed polyhedral connection nodes 3. The upper and lower hexagonal units are connected radially symmetrically, while the lower and semi-hexagonal units are connected tangentially. Specifically, a semi-hexagonal unit space is reserved symmetrically within the lower structure as a functional entrance and exit. This opening design maintains the overall stability of the structure while ensuring ease of use. This carefully designed geometric combination not only ensures the mechanical integrity of the Fuller sphere structure but also creates a unique visual effect and functional functionality.

[0124] The innovative design of the polyhedral connection nodes is crucial in the implementation: the outer diameter of the cannula is precisely matched to the inner diameter of the straw, and a friction-locking mechanism ensures a secure connection. A specially designed grounding connection between the support base and the upper Fuller sphere structure ensures overall structural stability while facilitating rapid assembly and disassembly on site. This design fully considers the various requirements of practical applications, significantly enhancing the device's practicality and maintainability while ensuring structural strength.

[0125] In fine weather, users can fully experience the spatial aesthetic value of the Fuller sphere straw structure: the transparent three-dimensional frame formed by its hollow geometric shape can accommodate immersive viewing functions - through the precisely arranged straw array, viewers can capture the refraction trajectory of natural light from a unique golden perspective and appreciate the visual feast of mottled light and shadow.
