Description

Technical Field

[0001] The utility model relates to the technical field of steel components, in particular to a prestressed cavity thin plate structure. Background Art

[0002] Cavity sheet is a sheet material with an internal cavity structure. Its design purpose is to reduce the amount and weight of materials while ensuring strength and rigidity. Cavity sheet is directly connected to the column to achieve its light and thin effect. It can be used in landscape, gas station, canopy and other structures. Moreover, the upper and lower parts are steel plates, which can save the cost of decorative layer. However, the interior of the cavity sheet at this stage does not have prestress, and the bearing capacity, rigidity and durability need to be improved. Utility Model Content

[0003] The utility model provides a prestressed cavity thin plate structure and solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] The prestressed cavity thin plate structure includes a longitudinal enclosure, a transverse enclosure, a transverse partition and a longitudinal partition. The transverse partition and the longitudinal partition are cross-arranged, and the transverse partition and the longitudinal partition enclose a cavity. A spring is installed in the cavity. The outer sides of the transverse partition and the longitudinal partition are surrounded by longitudinal enclosures and transverse enclosures, and the top and bottom of the transverse partition and the longitudinal partition are covered with cover plates.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the springs are evenly distributed in the cavities of the transverse partition and the longitudinal partition.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] Equidistantly distributed springs ensure that prestress is applied evenly throughout the structure. This evenly distributed stress helps avoid local stress concentration and reduces structural cracks or damage caused by excessive local stress, thereby improving the overall strength and durability of the structure. By evenly distributing springs throughout the structure, it can better resist various external loads, improve the bearing capacity and stability of the structure, and enhance the bending and shear resistance of the structure.

[0010] Furthermore, the transverse partitions and the longitudinal partitions are perpendicular to each other.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The mutually perpendicular transverse and longitudinal partitions form a more stable grid structure. This structure can effectively resist various forms of deformation caused by external loads, improving the stability and safety of the entire structure. The transverse and longitudinal partitions are perpendicular to each other, forming a solid cross-bracing structure. This design can effectively enhance the bending resistance of the structure, allowing the structure to withstand greater bending forces and reduce deformation and damage caused by bending.

[0013] Furthermore, the spring is in contact with the cover plates at both ends of the transverse partition and the longitudinal partition.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The spring contacts the cover plates at both ends of the partition, which can effectively transfer the prestress to the entire structure. This direct contact ensures that the prestress can be directly transferred to the structure, improving the efficiency and effect of prestress transfer. The design of the spring contacting the cover plate can ensure that the prestress is evenly distributed throughout the structure. This helps to avoid local concentration of prestress in the structure, reduces the risk of uneven deformation or stress concentration in the structure, and improves the stability and safety of the structure.

[0016] Furthermore, the longitudinal enclosure and the transverse enclosure are perpendicular to each other.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The vertical and horizontal panels form a cross-braced structural frame, which can effectively enhance the stability and rigidity of the structure. This design can effectively resist various forms of deformation caused by external loads and improve the overall stability of the structure. The vertical and horizontal panels form a structural grid that can effectively enhance the rigidity of the overall structure. This design can reduce the deformation and vibration of the structure during use and improve the stability and safety of the structure.

[0019] Furthermore, the spring is in a compressed state in the cavity.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The spring can provide greater prestress in a compressed state. This design ensures that after the spring is released, the spring can quickly release the prestress to the structure, effectively enhancing the stability and bearing capacity of the structure. The spring in a compressed state can evenly apply prestress to the structure. This helps to avoid local concentration of prestress in the structure, reduces the risk of uneven deformation or stress concentration in the structure, and improves the stability and safety of the structure. The spring can provide greater connection force in a compressed state, increases the contact area and connection strength between structural parts, and improves the overall stability and reliability of the structure.

[0022] Furthermore, the area of ​​the cover plate is adapted to the areas of the transverse partition plate and the longitudinal partition plate.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The matching of the area of ​​the cover plate with the area of ​​the partition can ensure the balanced distribution of force. The matching design can effectively transfer the load from the cover plate to the partition, avoiding structural damage or deformation caused by excessive local force. The matching cover plate design helps to improve the stability of the structure. The matching area of ​​the cover plate and the partition can ensure the uniform distribution of force and enhance the overall stability and bending resistance of the structure.

[0025] Furthermore, the longitudinal enclosure, cover plate, transverse enclosure, transverse partition and longitudinal partition are all steel plates with a thickness of 4 mm.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] Steel plates with a thickness of 4mm are used as the materials for longitudinal enclosures, covers, transverse enclosures, transverse partitions and longitudinal partitions. They have the advantages of high strength, lightweight design, strong corrosion resistance, good plasticity, high cost-effectiveness, easy maintenance, environmental sustainability and good structural stability.

[0028] The beneficial effects of the utility model are:

[0029] Prestress is applied in the cavity through compression springs to form an internal prestress field. This structural design enables the thin plate to resist part of the tensile stress and shear stress in advance when it is subjected to external loads, which can effectively improve the seismic performance and increase the overall strength and stiffness. Prestressed thin plates can better absorb and resist the energy of seismic waves under dynamic loads such as earthquakes, reducing vibration and damage to the structure. The presence of prestress can also improve the overall toughness of the structure, making it more stable and safer when responding to earthquakes.

[0030] The thin plate structure with cavity design is lighter than traditional solid plates, which not only reduces the amount of material used, but also reduces the difficulty and cost of transportation and installation. At the same time, in construction projects, reducing the self-weight of the structure can reduce the load on the infrastructure and improve the safety and durability of the overall building.

[0031] The springs are evenly spaced in the cavity to ensure that the prestress is applied evenly throughout the sheet structure. This evenly distributed stress avoids local stress concentrations, thus reducing the risk of cracks and damage to the sheet during use. The uniform prestress field also prolongs the service life of the structure and improves overall reliability and safety.

[0042] Embodiment 1

[0043] The prestressed cavity thin plate structure includes a longitudinal enclosure 1, a transverse enclosure 3, a transverse partition 4 and a longitudinal partition 5. The transverse partition 4 and the longitudinal partition 5 are arranged crosswise, and the transverse partition 4 and the longitudinal partition 5 are perpendicular to each other. The transverse partition 4 and the longitudinal partition 5 that are perpendicular to each other form a more stable grid structure. This structure can effectively resist various forms of deformation caused by external loads and improve the stability and safety of the entire structure. The transverse partition 4 and the longitudinal partition 5 are perpendicular to each other, forming a solid cross-support structure. Such a design can effectively enhance the bending resistance of the structure, so that the structure can withstand greater bending force and reduce deformation and damage caused by bending. The transverse partition 4 and the longitudinal partition 5 enclose a cavity 7, and a spring 6 is installed in the cavity 7. The spring 6 is compressed in the factory and released during construction. By releasing the spring 6, prestress is applied between the upper and lower cover plates 2. The spring 6 is in a compressed state in the cavity 7, and the spring 6 can provide greater prestress in a compressed state. This design ensures that after the spring 6 is released, the spring 6 can quickly release the prestress into the structure, effectively enhancing the stability and bearing capacity of the structure. The spring 6 in the compressed state can evenly apply prestress to the structure. This helps to avoid local concentration of prestress in the structure, reduces the risk of uneven deformation or stress concentration in the structure, and improves the stability and safety of the structure. The spring 6 can provide a greater connection force in the compressed state, increases the contact area and connection strength between the structural members, and improves the overall stability and reliability of the structure. The spring 6 contacts the cover plates 2 at both ends of the transverse partition 4 and the longitudinal partition 5. The spring 6 contacts the cover plates 2 at both ends of the partition, which can effectively transfer the prestress to the entire structure. This direct contact method ensures that the prestress can be directly transferred to the structure, improving the transmission efficiency and effect of the prestress. The design of the spring 6 in contact with the cover plate 2 can ensure that the prestress is evenly distributed throughout the structure. This helps to avoid local concentration of prestress in the structure, reduces the risk of uneven deformation or stress concentration in the structure, and improves the stability and safety of the structure. The springs 6 are evenly distributed in the cavities 7 of the transverse partitions 4 and the longitudinal partitions 5. The evenly distributed springs 6 can ensure that the prestress is evenly applied throughout the structure. This evenly distributed stress helps to avoid local stress concentration and reduce structural cracks or damage caused by excessive local stress, thereby improving the overall strength and durability of the structure. By evenly distributing the springs 6 throughout the structure, it is possible to better resist various external loads, improve the bearing capacity and stability of the structure, and enhance the bending and shear resistance of the structure. The outer sides of the transverse partitions 4 and the longitudinal partitions 5 are surrounded by longitudinal panels 1 and transverse panels 3, which are perpendicular to each other. The longitudinal panels 1 and transverse panels 3 that are perpendicular to each other form a cross-braced structural frame, which can effectively enhance the stability and rigidity of the structure. This design can effectively resist various forms of deformation caused by external loads and improve the overall stability of the structure.The structural grid formed by the longitudinal baffles 1 and the transverse baffles 3 being perpendicular to each other can effectively enhance the rigidity of the overall structure. This design can reduce the deformation and vibration of the structure during use, and improve the stability and safety of the structure. Cover plates 2 are provided above and below the transverse baffles 4 and the longitudinal baffles 5. The area of ​​the cover plates 2 is adapted to the area of ​​the transverse baffles 4 and the longitudinal baffles 5. The area of ​​the cover plates 2 is adapted to the area of ​​the baffles to ensure a balanced distribution of force. The adapted design can effectively transfer the load from the cover plate 2 to the baffles, avoiding structural damage or deformation caused by excessive local force. The adapted cover plate 2 design helps to improve the stability of the structure. Matching the area of ​​the cover plate 2 with that of the partition can ensure uniform distribution of force and enhance the overall stability and bending resistance of the structure. The longitudinal enclosure 1, cover plate 2, transverse enclosure 3, transverse partition 4 and longitudinal partition 5 are all 4 mm thick steel plates. 4 mm thick steel plates are used as the material of the longitudinal enclosure 1, cover plate 2, transverse enclosure 3, transverse partition 4 and longitudinal partition 5. It has the advantages of high strength, lightweight design, strong corrosion resistance, good plasticity, high cost-effectiveness, easy maintenance, environmental sustainability and good structural stability.

[0044] When the prestressed cavity thin plate structure based on Example 1 is used:

[0045] Prestress is applied in the cavity 7 by the compression spring 6 to form an internal prestress field. Such a structural design enables the thin plate to resist part of the tensile stress and shear stress in advance when it is subjected to external loads, which can effectively improve the seismic performance and improve the overall strength and stiffness. Prestressed thin plates can better absorb and resist the energy of seismic waves under dynamic loads such as earthquakes, reducing the vibration and damage of the structure. The presence of prestress can also improve the overall toughness of the structure, making it more stable and safer when responding to earthquakes.

[0046] The thin plate structure with cavity 7 design is lighter than the traditional solid plate, which not only reduces the material usage, but also reduces the difficulty and cost of transportation and installation. At the same time, in construction projects, reducing the deadweight of the structure can reduce the load on the infrastructure and improve the safety and durability of the overall building.

[0047] The springs 6 are evenly distributed in the cavity 7 to ensure that the prestress is evenly applied to the entire sheet structure. This evenly distributed stress can avoid local stress concentration, thereby reducing the risk of cracks and damage to the sheet during use. The uniform prestress field can also extend the service life of the structure and improve the overall reliability and safety.

[0048] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model.

However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
