Description

Technical Field

[0001] This invention relates to the field of architectural decoration, specifically to a spatial structure with a complex curved surface. Background Technology

[0002] Existing spatial curved surface structure systems form a grid structure by weaving and interweaving single rods or composite rods. Single rods are woven and interweaved with each other, and the points of single rods are connected to form a grid structure; composite rods are woven and interweaved with each other, and the points of composite rods are connected to form a grid structure.

[0003] However, the construction process is difficult or the material requirements are high. Based on this, the prior art discloses an invention patent with application number CN201910813048.7, which discloses a spatial curved surface structure system, including a skeleton structure of the spatial curved surface. The skeleton structure is a grid-like skeleton with two or more layers overlapping vertically or internally and externally. Each layer of the grid-like skeleton is a set of continuous, flexible elastic rods. The cross-section of the elastic rods is circular or annular. The elastic rods are interwoven and interlocked with each other by bending, and the connection of each connection point between the rods forms a self-forming grid-like skeleton. The connection points are hinged or rigid. The elastic rods serve as the force-bearing components of the grid-like skeleton and the forming components of the spatial curved surface contour. Summary of the Invention

[0004] To address the challenges of high construction difficulty and stringent material requirements in existing curved surface structures formed by weaving and interlacing single or composite rods, this invention provides a spatial structure with complex curved surface shapes. This significantly reduces construction difficulty, is suitable for constructing irregular curved surfaces, and allows for localized cleaning and repair as needed after construction without damaging other structures.

[0026] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0027] A spatial structure with a complex curved surface shape, such as Figure 1-3 As shown, the structure includes a framework 1, framework supports 2, connecting units, and a decorative layer. The framework 1, based on the design drawings, is constructed using steel. In this embodiment, a straw hat shape is used as an example. Several ring beams serve as the framework, each ring beam comprising several arc-shaped steel structures. These arc-shaped steel structures are connected by interlocking joints to form a closed ring beam. The interlocking joints of the arc-shaped steel structures are welded and fixed. The ring beams are arranged according to the design drawings and supported and fixed to the ground by the framework supports 2. Here, the ground refers to the supporting surface of the entire "straw hat" spatial structure, including but not limited to the Earth's surface. Several connecting units interweave to form a mesh structure 3, which is then placed over the framework 1. The edges of the mesh structure 3 are connected and fixed to the framework 1. Two ring beams are connected as a single unit via the mesh structure. A decorative layer is then installed on top of the mesh structure. The decorative layer can be made of rattan, LED strips, or similar materials wrapped around and attached to the mesh structure.

[0028] The frame support 2 is supported by steel columns. The two frame supports 2 are arranged in a V-shape. Support ear plates 4 are installed on the frame 2, and the upper ends of the two V-shaped frame supports 2 are hinged to the support ear plates 4. Figure 3 As shown, the structural frame 1 is supported on the ground by the support frame 2. The support frame 2 serves two purposes: it bears the load and it positions the ring steel beam.

[0029] The connecting unit includes a connecting part 6 and several connecting pieces. Several connecting pieces are connected to both ends of the connecting part 6. In this embodiment, four connecting pieces are connected to both ends of the connecting part 6. One end of the connecting piece is connected to the connecting part, and the other end of the connecting piece is connected to the adjacent connecting piece. For the edge position of the mesh structure, the other end of the connecting piece is connected to the shape skeleton.

[0030] One implementation of the connection unit is as follows: Figure 4-5 As shown, the connecting part 6 adopts a circular tube structure, and a reserved groove 7 is provided at both ends of the connecting part 6. The reserved groove 7 has an opening at the end near the connecting part. The connecting component includes a connecting plate 10 and a connecting head 11. The connecting head 11 is cylindrical and is installed at the end of the connecting plate 10. In use, the end with the connecting head 11 is inserted into the connecting part 6 through the opening of the reserved groove 7. The connecting plate 10 passes through the reserved groove 7, but the connecting head 11 cannot pass through the reserved groove 7. In order to fix the connecting component, a cover 8 is provided at both ends of the connecting part. The end of the connecting part and the inside of the cover are respectively provided with threads 12. The cover 8 is installed at both ends of the connecting part 6 by screwing. After the cover 8 is installed, it seals the opening of the reserved groove 7. The connecting part 6 is also provided with a fixing clip 9, which is installed between the connecting head 11 inserted into the reserved groove 7 and the cover 8 at the end of the connecting part.

[0031] During installation, four connectors at one end of a connecting part 6 are connected to the reserved slots at one end of the four connecting parts 6 respectively. Four connectors at the other end of the connecting part are then connected to the reserved slots at the other ends of the four connecting parts. These connecting units are connected sequentially to form a double-layered mesh structure. For connectors connecting between two connecting parts, both ends of the connecting plate 10 are provided with connector heads 11. For connectors connected to the styling frame at one end, no connector head is provided at the end of the connector connected to the styling frame; the connecting plate 10 is connected and fixed to the styling frame 1 by welding.

[0032] Another form of connection unit, such as Figure 6-7 As shown, the two ends of the connecting part are respectively provided with a first end 13 and a second end 14. The first end 13 and the second end 14 are respectively hinged to the two ends of the connecting part 6. The connecting member is a flexible connecting member, preferably a steel cable 19. The steel cable 19 is arranged crosswise at the positions of the first end 13 and the second end 14. The first end 13 and the second end 14 have the same structure, both including a first clamping plate 15 and a second clamping plate 16. The first clamping plate 15 and the second clamping plate 16 are respectively provided with pressure grooves 17. The back of the second clamping plate 16 is provided with a hinge joint 20. The connecting part is a cylindrical steel structure. The connecting part is connected to the second clamping plate 16 through the hinge joint 20. The first clamping plate 15 and the second clamping plate 16 are respectively provided with connecting holes 18. The sides of the first clamping plate 15 and the second clamping plate 16 with pressure grooves 17 are arranged opposite each other. The pressure grooves 17 on the first clamping plate 15 and the pressure grooves 17 on the second clamping plate 16 are arranged intersectingly. Bolts are inserted into the connecting holes 18 to fix the first clamping plate 15 and the second clamping plate 16 together. The steel cable 19 is finally pressed between the pressure grooves 17 of the first clamping plate 15 and the second clamping plate 16, and between the pressure grooves 17 on the second clamping plate 16 and the first clamping plate 15. For the second type of connecting unit, the end of the connector that is finally connected to the structural frame is also provided with an anchor head 21. Correspondingly, the structural frame 1 is also provided with a connecting ear plate 5. The anchor head 21 is in the form of a double ear plate, and the connection between the anchor head 21 and the connecting ear plate 5 is achieved by a pin. Figure 8 As shown.

Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
