Description

Technical Field

[0001] This utility model relates to the field of steel structures, and in particular to a single-layer reticulated steel structure with an irregular hyperboloid surface. Background Technology

[0002] With the continuous improvement of building technology and the gradual increase in people's requirements for architectural design, projects such as stadiums, large canopies, and railway station platforms composed of single-layer hyperboloid reticulated shell structures are becoming increasingly common. These projects not only require the structure to have sufficient load-bearing capacity and stability, but also require it to be aesthetically pleasing, have a short on-site construction cycle, and be able to achieve industrialized production. Therefore, irregular hyperboloid single-layer reticulated shell steel structures have emerged and have gradually developed into an important form of building structure.

[0003] A search revealed that patent CN219175477U proposes an irregularly shaped hyperboloid single-layer reticulated shell steel structure. This technical solution has the following problems:

[0004] When in use, this device can quickly install the steel mesh structure. However, the sealing gasket is located at the joint of the mesh, which exposes it to the outside for a long time, which may accelerate its aging. In addition, when maintenance is required, the device cannot quickly remove the mesh that needs to be replaced.

[0005] To address the aforementioned problems, this utility model document proposes an irregular hyperboloid single-layer reticulated steel structure. Utility Model Content

[0006] This utility model provides a non-circular hyperboloid single-layer reticulated steel structure, which solves the shortcomings of the prior art. While the device can quickly install the reticulated steel structure, the sealing gasket is located at the joint of the reticulated shell, which exposes it to the outside for a long time, which may accelerate its aging. In addition, the device cannot quickly remove the reticulated shell that needs to be replaced when maintenance is required.

[0007] This utility model provides the following technical solution:

[0008] A single-layer reticulated steel structure with an irregular hyperboloid surface includes a first crossbeam, one end of multiple first crossbeams is fixedly connected to the same longitudinal beam, and multiple second crossbeams are fixedly connected to the outer wall of the longitudinal beam;

[0009] The disassembly and assembly mechanism is located on top of the first and second crossbeams to facilitate the installation and disassembly of the grid shell steel structure.

[0010] An anti-aging mechanism is installed at the top of the first and second crossbeams to delay the aging of the steel structure of the reticulated shell.

[0011] In one possible design, the disassembly and assembly mechanism includes a slider, a first bolt, a first mesh shell, and a second mesh shell. One end of each of the first bolts passes through the bottom of the first crossbeam and the second crossbeam and is threaded into the interior of the sliders. The bottoms of the sliders are respectively attached to the tops of the first crossbeam and the second crossbeam. The bottoms of the first mesh shell and the second mesh shell are provided with multiple grooves, and the sliders are slidably connected to the interiors of the multiple grooves.

[0012] In one possible design, multiple first and second crossbeams are divided into two groups on average. Each group of first and second crossbeams has a connecting plate at its bottom. The two connecting plates have fixing holes inside, and each fixing hole is threaded with a second bolt.

[0013] In one possible design, the anti-aging mechanism includes a slot, a sealing frame, and a first sealing gasket. The slots are respectively opened on the top of the first mesh shell, and the bottoms of the sealing frames are fixedly connected to the top of the second mesh shell. The bottom of one of the sealing frames is slidably connected to the inside of one of the slots, and the tops of the first sealing gaskets are respectively fixedly connected to the top inner wall of the sealing frames.

[0014] In one possible design, a second sealing gasket is fixedly connected to one side of the second mesh shell.

[0015] In one possible design, the bottom of each set of first and second crossbeams is provided with multiple threaded holes, one end of each second bolt passes through the interior of multiple fixing holes and threaded holes and is threadedly connected to the interior of the first and second mesh shells, and rubber pads are fixedly connected to the bottom and top of the two connecting plates.

[0016] In one possible design, the outer walls of multiple first bolts are fitted with rubber rings.

[0017] In this application, during use, one end of multiple first and second crossbeams is fixedly connected to the longitudinal beam to ensure a stable connection. Then, multiple sliders are placed on top of the first and second crossbeams, ensuring that the bottom of the sliders fits against the surfaces of the first and second crossbeams. A first bolt is passed through the first and second crossbeams and threaded into the inside of the slider. A rubber ring is fitted on the outer wall of the first bolt to increase stability. Then, the sliding grooves at the bottom of the first and second mesh shells are aligned with the sliders, allowing the sliders to slide into the sliding grooves at the bottom of the first and second mesh shells, thus completing the initial installation. When a mesh shell needs to be repaired, the first bolt can be loosened, and the mesh shell along with the slider can be removed and replaced. Multiple slots are opened on the top of the first mesh shell. When the sliding grooves are aligned with the sliders, the bottom of the sealing frame can be slidably connected into the slots. A first sealing gasket is fixedly connected to the inner wall of the top side of the sealing frame to ensure sealing and prevent the first sealing gasket from aging too quickly. A second sealing gasket is fixedly connected to one side of the second mesh shell to further enhance the sealing effect.

[0018] In this utility model, the irregular hyperboloid single-layer reticulated steel structure, through the disassembly and assembly mechanism, can make the installation and disassembly process of the reticulated steel structure simple and quick, thereby improving the construction efficiency of the installers.

[0019] In this utility model, the irregular hyperboloid single-layer reticulated steel structure can prevent the external environment from corroding the reticulated steel structure through an anti-aging mechanism, thereby reducing the maintenance and replacement costs caused by aging.

[0020] In this utility model, the design of the disassembly and assembly mechanism and the anti-aging mechanism makes the irregular hyperboloid single-layer reticulated steel structure more practical in construction, maintenance and use. The disassembly and assembly mechanism improves construction efficiency and facilitates maintenance and replacement, while the anti-aging mechanism extends service life and improves structural safety.

[0030] The disassembly and assembly mechanism is located at the top of the first crossbeam 1 and the second crossbeam 3, facilitating the installation and disassembly of the grid shell steel structure. The mechanism includes sliders 4, first bolts 5, a first grid shell 7, and a second grid shell 8. One end of each first bolt 5 passes through the bottom of the first crossbeam 1 and the second crossbeam 3 and is threaded into the interior of each slider 4. The bottoms of the sliders 4 are respectively attached to the tops of the first crossbeam 1 and the second crossbeam 3. The bottoms of the first grid shell 7 and the second grid shell 8 are each provided with multiple grooves, and the sliders 4 are slidably connected within these grooves, allowing the sliders 4 to be placed... Place the slider 4 on top of the first crossbeam 1 and the second crossbeam 3, ensuring that the bottom of the slider 4 is in contact with the surfaces of the first crossbeam 1 and the second crossbeam 3. Use the first bolt 5 to pass through the first crossbeam 1 and the second crossbeam 3 and thread it into the inside of the slider 4. The rubber ring 6 is fitted on the outer wall of the first bolt 5 to increase stability. Then, align the sliding grooves at the bottom of the first mesh shell 7 and the second mesh shell 8 with the slider 4, so that the slider 4 slides into the sliding grooves at the bottom of the first mesh shell 7 and the second mesh shell 8, thus completing the initial installation. When it is necessary to repair a mesh shell, the first bolt 5 can be loosened, and the mesh shell along with the slider 4 can be removed and replaced.

[0031] An anti-aging mechanism is installed on the top of the first crossbeam 1 and the second crossbeam 3 to delay the aging of the steel structure of the mesh shell. The anti-aging mechanism includes slots 9, sealing frames 10, and first sealing gaskets 11. Multiple slots 9 are respectively opened on the top of the first mesh shell 7. The bottoms of multiple sealing frames 10 are fixedly connected to the top of the second mesh shell 8. The bottom of one sealing frame 10 is slidably connected to the inside of one of the slots 9. The tops of multiple first sealing gaskets 11 are respectively fixedly connected to the inner wall of the top side of multiple sealing frames 10. Multiple slots 9 are opened on the top of the first mesh shell 7. When the sliding groove is aligned with the slider 4, the bottom of the sealing frame 10 can be slidably connected to the slot 9 at the same time. The first sealing gaskets 11 are fixedly connected to the inner wall of the top side of the sealing frame 10 to ensure sealing and prevent the first sealing gaskets 11 from aging too quickly. A second sealing gasket 12 is fixedly connected to one side of the second mesh shell 8 to further enhance the sealing effect.

[0032] This application can be used in the field of steel structures, or in other fields applicable to this application.

[0033] Example 2

[0034] Based on Example 1, the following improvements were made:

[0035] A type of irregular hyperboloid single-layer reticulated shell steel structure, whose applications in the field of steel structures include:

[0036] Multiple first crossbeams 1 and second crossbeams 3 are divided into two groups. Each group of first crossbeams 1 and second crossbeams 3 has a connecting plate 15 at its bottom. The two connecting plates 15 have fixing holes inside, and each fixing hole is threaded with a second bolt 13. The bottom of each group of first crossbeams 1 and second crossbeams 3 has multiple threaded holes 14. One end of each second bolt 13 passes through the multiple fixing holes and threaded holes 14 and is threaded into the inside of the first mesh shell 7 and the second mesh shell 8. Rubber pads 16 are fixedly connected to the bottom and top of the two connecting plates 15, so that the second bolts 13 can further fix the first crossbeams 1 and second crossbeams 3, thereby enhancing the stability of the mesh shell steel structure.

[0037] The second sealing gasket 12 is fixedly connected to one side of the second mesh shell 8, which further enhances the sealing performance of the mesh shell steel structure and extends the service life of the mesh shell steel structure.
