Description

Technical Field

[0001] This utility model belongs to the field of spatial steel structure technology, and particularly relates to an edge-suspended space frame structure. Background Technology

[0002] Currently, material storage yards generally use facilities such as enclosures and windbreak / dust suppression nets. Since 2019, the Ministry of Ecology and Environment has explicitly required that materials such as iron ore concentrate, coal, coke, sintered ore, pellets, limestone, dolomite, ferroalloys, and steel slag must be stored in enclosed silos or sheds. Therefore, material yards that previously used enclosures and windbreak / dust suppression nets need to be renovated and enclosed. The common practice is to dismantle the existing facilities and build new sheds. This approach has drawbacks such as high investment, long construction periods, and disruption to production.

[0003] Space frame structures are very suitable for material yard enclosure projects due to their advantages such as large span, flexible column arrangement, and quick construction. They can achieve the goal of not damaging the original facilities, shortening the construction period, and reducing adverse impacts on production. However, space frame structures are flat or slightly curved spatial structures, and there are generally large gaps between the structure itself and the original enclosure facilities, which makes enclosure relatively difficult. Utility Model Content

[0004] The purpose of this utility model is to provide an edge-suspended grid structure that can make full use of existing fencing facilities, thereby reducing project costs and shortening the construction period.

[0005] This utility model is implemented as follows: an edge-suspended space frame structure includes a space frame structure, with several supporting columns arranged along its perimeter inside the lower part of the space frame structure to form multi-point support inside the space frame structure. The key feature is that it also includes an edge-suspended structure and wall-mounted columns. The edge-suspended structure is one or more layers located at the edge of the space frame structure and connected to the lower part of the space frame structure. The wall-mounted columns are placed vertically and arranged sequentially along the horizontal direction of the edge-suspended structure. The wall-mounted columns and the edge-suspended structure are connected by ball joints, and the lower end of the wall-mounted columns extends downwards to the original enclosure facility.

[0006] As a further description of the above technical solution: the grid structure adopts a quadrangular pyramid system, which consists of multiple inverted quadrangular pyramids A arranged in a horizontal array and connecting rods A. The connecting rods A are located below the quadrangular pyramids A, and the cone ends of the quadrangular pyramids A are connected sequentially through the connecting rods A.

[0007] The inverted quadrangular pyramid A includes chord A and diagonal braces A. There are four chord A members, connected end to end to form a rectangular shape, which is placed horizontally. There are also four diagonal braces A members. The upper ends of the diagonal braces A are connected to the ends of the chord A members, and the lower ends of the diagonal braces A members converge at a point, namely the cone end.

[0008] As a further description of the above technical solution: When the edge overhang structure is a single overhang unit A, the overhang unit A consists of three chords B and two diagonal braces B. Two of the three chords B are placed vertically and one is placed horizontally. The lower ends of the vertically placed chords B are connected to the two ends of the horizontally placed chords B, and the upper ends of the vertically placed chords B are connected to the two ends of the chords A of the space frame structure, forming a rectangular shape. The lower ends of the two diagonal braces B and the upper ends of the two diagonal braces A of the space frame structure are connected to the endpoints of this rectangle. The upper ends of the two diagonal braces B and the lower ends of the two diagonal braces A of the space frame structure converge at the same point, forming a sideways quadrangular pyramid B. The edge overhang structure forms an integral force-bearing system with the space frame structure through the outermost chords A, diagonal braces A, and connecting rods A of the space frame structure.

[0009] As a further description of the above technical solution: When the edge overhang structure is a multi-layer overhang unit, the edge overhang structure consists of a layer of overhang units A arranged sequentially, a layer or more of overhang units B arranged sequentially, and connecting rods B. Overhang units A are on top, and overhang units B are on the bottom. Overhang unit B consists of three chords C and four diagonal braces C. Two of the three chords C are placed vertically and one is placed horizontally. The lower ends of the vertically placed chords C are connected to the two ends of the horizontally placed chords C, and the upper ends of the vertically placed chords C are connected to the two ends of the chords B of overhang unit A. The four chords are connected end to end to form a rectangular shape. The outer ends of the diagonal braces C are connected to the endpoints of this rectangle, and the inner ends of the diagonal braces C converge at the same point to form a side-placed quadrangular pyramid C. The cone end of the quadrangular pyramid C is on the inside, and the cone end of the quadrangular pyramid C is connected sequentially through horizontal connecting rods B. The cone ends of quadrangular pyramid B and quadrangular pyramid C are connected through vertical connecting rods B.

[0010] As a further description of the above technical solution: the wall frame columns are arranged vertically along the suspension structure, and are set up in parallel with the vertically placed chord B of the suspension structure. They are connected to both ends of the vertically placed chord B. The two ends of the vertically placed chord B are ball nodes, and the ball nodes have small columns and end plates. The wall frame columns are connected to the small columns and end plates. The lower end of the wall frame column extends out of the lower ball node, and the extension length is less than or equal to the distance between the two ball nodes of the vertically placed chord B.

[0011] The advantages of this utility model are:

[0012] This utility model solves the gap problem between any space frame structure and the original enclosure by setting a hanging structure at the lower edge of the space frame structure and combining it with the cantilever of the wall frame column. It can realize the closed renovation on the basis of making full use of the original enclosure, which reduces project costs, shortens the construction period and reduces the adverse impact on production.

[0023] like Figures 1-7As shown, this utility model discloses an edge-suspended space frame structure, including a space frame structure 3. Several support columns 2 are arranged along the periphery of the lower inner side of the space frame structure 3 to form multi-point support inside the space frame structure 3. The feature is that it also includes an edge-suspended structure 4 and wall frame columns 5. The edge-suspended structure 4 is a single or multiple edge-suspended structure located at the edge of the space frame structure and connected to the lower part of the space frame structure 3. The wall frame columns 5 are placed vertically and arranged sequentially along the horizontal direction of the edge-suspended structure 4. The wall frame columns 5 are connected to the edge-suspended structure 4 through ball joints, and the lower end of the wall frame columns 5 extends downward to the original enclosure facility.

[0024] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the grid structure 3 consists of multiple inverted quadrangular pyramids A31 and connecting rods A32 arranged in a horizontal array. The connecting rods A32 are located below the quadrangular pyramids A31, and the cone ends of the quadrangular pyramids A31 are connected sequentially through the connecting rods A32.

[0025] The inverted quadrangular pyramid A31 of this utility model includes chord bars A311 and diagonal braces A312. There are four chord bars A311, which are connected end to end to form a rectangular shape, preferably a square, and are placed horizontally. There are four diagonal braces A312. The upper ends of the diagonal braces A312 are connected to the ends of the chord bars A311 respectively, and the lower ends of the diagonal braces A312 converge at a point, namely the cone end.

[0026] like Figure 3 and Figure 4 As shown, the edge overhang structure of this utility model consists of a layer of overhang units A41 arranged sequentially in the horizontal direction. Each overhang unit A41 comprises three chord members B411 and two diagonal web members B412. Two of the chord members B411 are placed vertically, and one is placed horizontally. The lower ends of the vertically placed chord member B411 are connected to both ends of the horizontally placed chord member B411, and the upper ends of the vertically placed chord member B411 are connected to both ends of the chord member A311 of the space frame structure, forming a rectangular shape. The lower ends of the two diagonal web members B412 and the upper ends of the two diagonal web members A312 of the space frame structure are connected to the four endpoints of the rectangle, respectively. The upper ends of the two diagonal web members B412 and the lower ends of the two diagonal web members A312 of the space frame structure intersect at the same point, forming a side-placed quadrangular pyramid B. The edge suspension structure 4 forms an integral force system with the space frame structure 3 through the outermost chord A311, diagonal web members A312 and connecting rod A32. The structure has good stability, high load-bearing capacity, large stiffness and small deformation.

[0027] like Figure 5As shown, the wall frame columns 5 are arranged vertically along the suspended structure 4, parallel to the vertically placed chord members B411 of the suspended structure 4, and connected to both ends of the vertically placed chord members B411. The two ends of the vertically placed chord members B411 are ball joints, each ball joint 6 with a small column and end plate 7. The wall frame columns 5 are connected to the small columns and end plates 7, and the connection method can be bolted or welded. The lower end of the wall frame column 5 extends beyond the lower ball joint 6, with the extension length being less than or equal to the distance between the two ball joints 6 of the vertically placed chord members B411. Combined with the cantilevered lower end of the wall frame columns, the gap problem between any space frame structure and existing fencing and other facilities can be solved, enabling closed renovations to be completed while fully utilizing existing fencing and other facilities.

[0028] like Figure 6 and Figure 7 As shown, as another embodiment of the above technical solution, the structure of the space frame 3 and the suspension unit A41 in this embodiment of the present invention are the same as those in the above embodiment. When the edge suspension structure of the present invention is a multi-layer suspension unit, the edge suspension structure 4 is composed of a layer of suspension units A41 arranged in sequence, a layer or more of suspension units B42 arranged in sequence, and connecting rods B43. Suspension unit A41 is on top, and suspension unit B42 is on the bottom. Suspension unit B42 is composed of three chords C421 and four diagonal web members C422. Two of the three chords C421 are placed vertically, and one is placed vertically. The lower ends of the horizontally placed and vertically placed chord members C421 are connected to both ends of the horizontally placed chord member C421, and the upper ends of the vertically placed chord members C421 are connected to both ends of the chord member B421 of the suspension unit A41. The four chord members are connected end to end to form a rectangle. The outer ends of the diagonal web members C422 are connected to the endpoints of this rectangle, and the inner ends of the diagonal web members C422 converge at the same point to form a side-placed quadrangular pyramid C. The cone end of the quadrangular pyramid C is on the inside, and the cone end of the quadrangular pyramid C is connected sequentially through the horizontal connecting rod B43. The cone ends of the quadrangular pyramids B and C are connected through the vertical connecting rod B43. The multi-layered edge suspension structure can meet the requirement of a larger gap between the structure itself and the original enclosure facilities. At the same time, like the single-layered edge suspension structure, the multi-layered edge suspension structure forms an integral force system with the space frame structure, and also has the advantages of good structural stability, high load-bearing capacity, large stiffness and small deformation.

[0029] When the edge overhang structure is a multi-layer overhang unit, the wall frame column 5 is connected to the lowest four-corner pyramid, and the specific connection is the same as in the above embodiment.

[0030] In addition to the quadrangular pyramid form used in the above embodiments, the edge overhang structure 4 can also adopt other space frame structure forms such as cross trusses and triangular pyramids.

[0031] This utility model's edge-suspended space frame structure, by setting a suspension structure at the edge of the space frame structure, can close with the original fence to achieve the function of enclosing the material yard, avoiding demolition and reconstruction, thus reducing project costs and shortening the construction period.

[0032] This invention not only enriches the types of space frame structure systems, but also broadens the application scope of space frame structures.
