Description

Technical Field

[0001] This invention relates to the field of civil engineering structures, and more specifically to a spatial grid structure system. Background Technology

[0002] Spatial grid structures are a commonly used structural system in large-span buildings, including forms such as space trusses and space frames. Besides meeting safety and economic requirements, these structures must also conform to the spatial requirements of the building. Traditional spatial structures, such as spatial trusses and space frames, offer high structural efficiency and are convenient to manufacture and construct. However, the overlapping of web members and chords in space results in a lack of innovation and is incompatible with the diverse spatial forms required in contemporary architectural design. Furthermore, the traditional spatial structure layout is relatively simple and mechanized, making it particularly unsuitable for cultural and creative buildings and traditional ancient architecture.

[0003] As architects increasingly demand integrated structural architecture, the rigid spatial grid structures of existing technologies cannot meet the needs of creative architectural spaces. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a spatial grid structure that achieves the goal of exposing the structure and meeting the spatial and aesthetic requirements of cultural and creative buildings, while also satisfying the requirements of reasonable structural stress and convenient construction.

[0005] The technical solution is as follows: a spatial grid structure, comprising a single-layer perforated roof in a cross-grid pattern, a spatial lattice roof truss, and horizontal steel cables; horizontal steel cables are connected to the top of the vertical structure, and the horizontal steel cables are closed, segmented at certain intervals to form several segment points, which are the first nodes of the structure; from each first node of the structure, the first component of the spatial lattice roof truss is led upward along the diagonal direction of an inverted quadrangular pyramid, the other end of the first component is the second node of the structure, and the second node of the structure is also the intersection point of adjacent first components; from each second node of the structure, the second component of the spatial lattice roof truss is led upward along the diagonal direction of an inverted quadrangular pyramid, the other end of the second component is the third node of the structure, and the third node of the structure is also the intersection point of adjacent second components; from each third node of the structure, the third component of the spatial lattice roof truss is led upward along the diagonal direction of an inverted quadrangular pyramid, the other end of the third component is the fourth node of the structure, and the fourth node of the structure is also the intersection point of adjacent third components; adjacent fourth nodes of the structure are connected by connecting rods to form a single-layer perforated roof.

[0006] Based on the above technical features: the fourth node of the structure located on the inner hollow edge of the single-layer hollow roof extends inward to generate a complete grid component that fills the hollow space of the single-layer hollow roof to form a second roof, and the second roof and the single-layer hollow roof are integrated into one.

[0007] Based on the above technical features: a single-layer perforated roof is either a single-layer curved surface or a single-layer flat surface.

[0008] Based on the above technical features: the second roof is a single-layer curved surface or a single-layer flat surface.

[0009] Both the second roof and the single-layer perforated roof can have arbitrary curved or planar shapes, which can be adjusted according to the actual project. The materials for the first, second, and third components and connecting rods can be metal, wood, or other types of engineering materials, depending on the actual situation. The first, second, third, and fourth structural nodes can be selected as welded or assembled, depending on the on-site construction precision conditions and the factory prefabrication level.

[0010] The working principle of this technology is as follows: the closed horizontal steel cable forms a stable triangle with the first component of the spatial lattice roof truss, thereby constraining the displacement of the second node of the spatial lattice roof truss; the connecting rod of the single-layer openwork roof and the third component of the spatial lattice roof truss form a stable inverted quadrangular pyramid system, thereby constraining the displacement of the third node of the spatial lattice roof truss; the structural load is transferred and converged from top to bottom along the spatial lattice roof truss. All nodes in the entire system can maintain structural stability, forming a reliable structural system.

[0011] The beneficial effects of the present invention are as follows: The spatial grid structure of the present invention aims to provide a spatial grid structure that is reasonably stressed, convenient to construct, safe and reliable, which satisfies both the structural stress requirements and the architectural spatial form.

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0025] like Figures 1 to 7 As shown, this structural system includes a single-layer perforated roof with a cross-grid pattern, a spatial lattice roof truss, and horizontal steel cables A; the horizontal steel cables A are closed and can be enclosed into circles, ellipses, rectangles, and polygons. Figure 3 and Figure 8 The horizontal steel cable shown is rectangular and is for illustrative purposes only.

[0026] A horizontal steel cable A is connected to the top of the vertical structure, which includes columns, walls, etc.

[0027] The horizontal steel cable A is divided into several segments at certain intervals, and the segment points are the first nodes N1 of the structure; the intervals between the segments can be equal or different.

[0028] From each structural node N1, the first component B1 of the spatial lattice roof truss is drawn upwards along the diagonal direction of the inverted quadrangular pyramid. The other end node of the first component B1 is the structural node N2, which is also the intersection point of adjacent first components B1. From each structural node N2, the second component B2 of the spatial lattice roof truss is drawn upwards along the diagonal direction of the inverted quadrangular pyramid. The other end node of the second component B2 is the structural node N3, which is also the intersection point of adjacent second components B2. From each structural node N3, the third component B3 of the spatial lattice roof truss is drawn upwards along the diagonal direction of the inverted quadrangular pyramid. The other end node of the third component B3 is the structural node N4, which is also the intersection point of adjacent third components B3. Connecting rods C connect adjacent structural nodes N4 to form a single-layer perforated roof. A top view of the single-layer perforated roof can be found in [reference needed]. Figure 6 That is, to form a roof frame with a hollow center.

[0029] like Figures 1 to 7 As shown, the fourth node of the structure located on the inner perforated edge of the single-layer perforated roof extends inward to form a complete grid component, filling the perforated space of the single-layer perforated roof to form a second roof. The second roof and the single-layer perforated roof are integrated into one unit. The single-layer perforated roof and the second roof shown in the figure use the same grid shape for illustration only; the grid shapes of the two can be different.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
