Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings. More specifically, the utility model relates to a lightweight steel structure shear-resistant energy-dissipating multi-story steel frame structure. Background Technique

[0002] The lightweight steel structure shear-resistant energy-dissipating multi-story steel frame structure is a building structure form that combines lightweight design, shear resistance, and energy-dissipating mechanisms. This structure mainly uses lightweight steel materials as the main building materials, such as light steel frames, steel columns, steel beams, etc. The density of steel is relatively low, but its strength, stiffness, and toughness are excellent, enabling the overall structure to maintain high load-bearing capacity and stability while reducing its own weight. For example, lightweight materials such as thin-walled steel sections and cold-formed thin-walled steel sections are used, and the cross-sectional shape is optimized (such as I-shaped, box-shaped, etc.) to reduce the material consumption.

[0003] Among them, the patent with the publication number CN216766946U discloses a lightweight steel structure standard design shear-resistant energy-dissipating support module, which has a frame welded by metal materials. The frame is in a rectangular structure and is composed of two vertically symmetrically arranged vertical rods on the left and right and two horizontal rods symmetrically and fixedly welded to the upper and lower ends of the vertical rods; four corner strengthening plates are fixedly welded at the four corners inside the frame, and an energy-dissipating steel plate is arranged at the center. V-shaped members are arranged between the two corner strengthening plates at the upper end and the energy-dissipating steel plate and between the two corner strengthening plates at the lower end and the energy-dissipating steel plate inside the frame;

[0004] When this structure is in use, the relative movement trend of the upper and lower two V-shaped members in the lightweight steel structure standard design shear-resistant energy-dissipating support module causes the energy-dissipating steel plate to undergo elastic deformation. Process holes are designed on the energy-dissipating steel plate to facilitate the dissipation of force. This process will dissipate a large amount of seismic force, thereby greatly reducing the damage degree of the seismic force to the main structure members of the steel structure building. However, this structure is not easy to reduce the impact force received at its top by itself, resulting in a decrease in the anti-deformation and support performance of the device. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a lightweight steel structure shear-resistant energy-dissipating multi-story steel frame structure, aiming to solve the problems proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A lightweight steel structure shear-resistant energy-dissipating multi-story steel frame structure, including a support base, a central limit sleeve for positioning is arranged above the support base, and a plurality of support triangular members are distributed around the support base;

[0007] Extension rods are provided at the top ends of the plurality of supporting triangles, and lower support rods are provided between each two adjacent supporting triangles. The lower support rods and the extension rods are inclined upward, and the tops of the lower support rods and the extension rods extend to the outside of the center limit sleeve and are detachably connected to the center limit sleeve by bolts.

[0008] It can be seen that in the above technical solution, the lower push rod and the extension rod are inclined upward and extend to the outside of the central limiting sleeve, and are limited by the central limiting sleeve, so that the supporting triangle, the lower push rod and the extension rod and other structures are connected with the central limiting sleeve, so that when the top of the device is impacted, the central limiting sleeve will pressurize the lower push rod and the extension rod, so that the lower push rod and the extension rod are subjected to force, and when the lower push rod and the extension rod are subjected to force, the force will be dispersed to each supporting triangle for release, thereby ensuring the deformation resistance and impact resistance of the device, and also facilitating installation;

[0009] Optionally, in a possible implementation, the vertical cross-sections of the plurality of support triangles are all triangular in shape, and each of the support triangles is detachably connected to the support base, bracket members are provided on both sides of the bottom of the inner walls of the plurality of support triangles, and the bottom of each of the bracket members is provided on the support base, the bracket member and the support base are detachably connected by bolts, a plurality of linkage cross bars are provided on the outer sides of the support triangles, the lower push rods and the extension rods, and each of the linkage cross bars is detachably connected to the support triangles, the lower push rods and the extension rods, respectively, the plurality of support triangles are provided on the outer sides of the support base, and the bottom of each of the lower push rods is respectively provided at one end of the bottom of two adjacent support triangles;

[0010] It can be seen that in the above technical solution, each supporting triangle is installed on the supporting base by bolts, each extension rod is installed at the top of the supporting triangle, and each lower support rod is installed between two adjacent supporting triangles, so that the extension rod can be in contact with the bottom end of the supporting triangle. Through each linkage cross rod, it is easy to drive the remaining lower support rods and extension rods to be linked when one of the lower support rods and extension rods is subjected to force, which is easy to disperse the pressure and improve the deformation resistance of the device.

[0011] Technical effects and advantages of the utility model:

[0012] Through the corresponding coordinated use of various structures, the lower support rod and the extension rod are tilted upward and extended to the outside of the center limit sleeve, and are limited by the center limit sleeve, so that the supporting triangle, the lower support rod and the extension rod and other structures are connected together with the center limit sleeve. When the top of the device is impacted, the center limit sleeve will pressurize the lower support rod and the extension rod when it is displaced, so that the lower support rod and the extension rod are subjected to force, and when the lower support rod and the extension rod are subjected to force, the force will be dispersed to each supporting triangle for force release, thereby ensuring the device's anti-deformation and impact performance.

[0013] Meanwhile, the utility model is also convenient for installation. Through each linkage cross bar, it is easy for one lower abutting rod and the extension rod to drive the other lower abutting rods and extension rods to be linked when stressed, which is conducive to dispersing the pressure and improving the anti-deformation performance of the device.

[0022] Extension rods 5 are provided at the top ends of the multiple supporting triangles 3, and a lower support rod 4 is provided between each two adjacent supporting triangles 3.
