A seismic-resistant prefabricated steel frame

Abstract

This utility model discloses an earthquake-resistant prefabricated steel structure frame, including an earthquake-resistant mechanism, a column mechanism, and a beam mechanism. Multiple column mechanisms are respectively located at the four corners of the upper surface of the earthquake-resistant mechanism. The beam mechanism is bolted to the upper end between two adjacent column mechanisms. The earthquake-resistant mechanism also includes a base, a boss, and a mounting plate. High-earthquake earthquake-resistant mechanisms are fixedly installed at the four corners of the upper surface of the base. The boss is located at the center of the upper surface of the base, and a micro-earthquake earthquake-resistant mechanism is bolted to the center of the upper surface of the boss. The column mechanism and beam mechanism are then installed on the upper end of the earthquake-resistant mechanism. When a small earthquake occurs, the micro-earthquake earthquake-resistant mechanism absorbs the amplitude. When a large-amplitude vibration occurs, the micro-earthquake earthquake-resistant mechanism dissipates the amplitude, thereby reducing the impact on the high-earthquake earthquake-resistant mechanism and the micro-earthquake earthquake-resistant mechanism at the upper end of the earthquake-resistant mechanism and improving the earthquake resistance of the steel structure frame.

Description

Technical Field

[0001] This utility model relates to the field of steel structure frame technology, and in particular to an earthquake-resistant prefabricated steel structure frame. Background Technology

[0002] Prefabricated steel frame structures are a type of building load-bearing system that uses factory-prefabricated steel structural components as its core and connects them through standardized nodes. The components undergo cutting, welding, and painting processes in the factory, resulting in high precision and controllable quality. On-site construction primarily uses bolt connections or minimal welding, significantly reducing wet work and greatly improving construction efficiency and shortening the construction period. Simultaneously, this structural system combines the advantages of lightweight, high-strength, and good plasticity and toughness of steel structures, and the components are recyclable, aligning with green building and sustainable development concepts. It is widely used in industrial plants, high-rise buildings, public buildings, and other fields.

[0003] The existing prefabricated steel frame structure still has significant shortcomings in terms of seismic performance: the seismic structural measures are not perfect, most frames do not have dedicated energy dissipation components, and rely solely on the plastic deformation of the components themselves to dissipate seismic energy. Under strong earthquakes, they are prone to failure due to excessive deformation. Furthermore, the coordination between the support system and the main frame is poor, making it difficult to form an effective lateral force resisting system.

[0004] Therefore, this application provides a seismic-resistant prefabricated steel structure frame. Utility Model Content

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 6 As shown, this application provides a seismic-resistant prefabricated steel structure frame, comprising:

[0028] The steel frame 100 includes an anti-seismic mechanism 10, a column mechanism 20, and a beam mechanism 30. Multiple column mechanisms 20 are respectively located at the four corners of the upper surface of the anti-seismic mechanism 10. The beam mechanism 30 is fixedly installed at the upper end between two adjacent column mechanisms 20 by bolts. The anti-seismic mechanism 10 also includes a base 11, a boss 13, and a mounting plate 15. High-seismic anti-seismic mechanisms 12 are fixedly installed at the four corners of the upper surface of the base 11. The boss 13 is located at the center of the upper surface of the base 11. A micro-seismic anti-seismic mechanism 14 is fixedly installed at the center of the upper surface of the boss 13 by bolts. The mounting plate 15 is fixedly installed on the top of the high-seismic anti-seismic mechanism 12 and the micro-seismic anti-seismic mechanism 14 by bolts.

[0029] After adopting the above technical solution, by setting a high-earthquake anti-seismic mechanism 12 and a micro-earthquake anti-seismic mechanism 14 inside the seismic anti-seismic mechanism 10, and then installing the support mechanism 20 and the beam mechanism 30 on the upper end of the seismic anti-seismic mechanism 10, when a small earthquake occurs, the micro-earthquake anti-seismic mechanism 14 consumes the amplitude, thereby reducing the impact on the high-earthquake anti-seismic mechanism 12 and the micro-earthquake anti-seismic mechanism 14 at the upper end of the seismic anti-seismic mechanism 10. When a large-amplitude vibration occurs, the micro-earthquake anti-seismic mechanism 14 disconnects and consumes the amplitude, thereby reducing the impact on the high-earthquake anti-seismic mechanism 12 and the micro-earthquake anti-seismic mechanism 14 at the upper end of the seismic anti-seismic mechanism 10, and improving the seismic resistance of the steel structure frame.

[0030] It should be noted that during the installation of the steel structure frame, a foundation pit is first excavated in the installation area, then concrete is poured at the bottom of the pit, and then the seismic resisting mechanism 10 is placed inside the pit. After the seismic resisting mechanism 10 is installed, the support column mounting base 21 is fixed to the four corners of the upper surface of the seismic resisting mechanism 10 with bolts to complete the installation of the support column. After the support column is installed, the beam mechanism 30 is hoisted and the connecting boss 32 at the end of the beam mechanism 30 is placed into the connecting groove 23 at the top of the column 22 and fixed with bolts to complete the installation of the steel structure frame. When a small earthquake occurs during the use of the steel structure frame, the base 11 will move along with the ground movement trajectory. At this time, the base 11 drives the micro-seismic base plate 141 to move together. During the movement of the micro-seismic base plate 141, the high-viscosity silicone oil in the seismic cavity 147 and the extrusion plate 146 move relative to each other. Through the friction and shearing action between the high-viscosity silicone oil and the extrusion plate 146, mechanical energy is converted into... Heat energy is dissipated, thus attenuating vibrations and improving the seismic resistance of the steel frame structure when facing small vibrations. When a large earthquake occurs during the use of the steel frame structure, since fracture openings 149 are set on both sides of the upper end of the connecting column 145, when the amplitude exceeds the maximum deformation range of the connecting column 145, the connecting column 145 breaks at the fracture opening 149, and the amplitude directly acts on the high-vibration base plate 121. The high-vibration base plate 121 moves significantly due to the amplitude. During this process, the lower end of the lead column 122 moves and deforms simultaneously with the high-vibration base plate 121. Due to the physical properties of the high-vibration base plate 121, it will not break after deformation. At the same time, during the deformation of the high-vibration base plate 121, it is supported by the stacked steel discs 125. Rubber discs 124 are set between the two steel discs 125 to reduce the friction generated by the two steel discs 125 during movement, so that the steel frame structure has multiple seismic resistance effects.

[0031] In an optional embodiment, the high-earthquake anti-seismic mechanism 12 includes a high-earthquake base plate 121 fixedly installed at the four corners of the upper surface of the base 11. A lead column 122 is fixedly installed at the center of the upper surface of the high-earthquake base plate 121, and a high-earthquake top plate 123 is fixedly installed on the top of the lead column 122. Multiple rubber discs 124 and steel discs 125 are provided on the outer wall of the lead column 122. The multiple rubber discs 124 and steel discs 125 are arranged in pairs at intervals. When the high-earthquake base plate 121 moves significantly due to the amplitude, the lower end of the lead column 122 moves and deforms simultaneously with the high-earthquake base plate 121. Due to the physical properties of the high-earthquake base plate 121, it will not break after deformation. At the same time, during the deformation process of the high-earthquake base plate 121, it is supported by the stacked steel discs 125. Meanwhile, the rubber discs 124 are placed between the two steel discs 125 to reduce the friction generated by the two steel discs 125 during movement, thereby improving the seismic resistance of the steel structure frame.

[0032] In one optional embodiment, the micro-vibration damping mechanism 14 includes a micro-vibration base plate 141 fixedly installed at the center of the upper surface of the boss 13. A damping box 142 is fixedly installed on the top of the micro-vibration base plate 141. Multiple uniformly distributed damping cavities 147 are provided on both the left and right sides inside the damping box 142. A connecting column 145 is inserted into the center of the damping box 142. The upper end of the connecting column 145 extends out of the damping box 142. A high-vibration top plate 143 is welded to the top of the connecting column 145. The connecting column 145 is integrally located on one side inside the damping box 142. Multiple uniformly distributed extrusion plates 146 are provided, and the extrusion plates 146 are slidably connected to the inside of the seismic cavity 147. High-viscosity silicone oil is filled between the extrusion plates 146 and the seismic cavity 147. During the movement of the micro-vibration base plate 141 under the influence of vibration amplitude, the high-viscosity silicone oil in the seismic cavity 147 and the extrusion plates 146 move relative to each other. Through the friction and shearing action between the high-viscosity silicone oil and the extrusion plates 146, mechanical energy is converted into heat energy and dissipated, thereby attenuating vibration and improving the seismic resistance of the steel structure frame when facing small vibrations.

[0033] In an optional embodiment, a rubber ring 148 is fixedly installed at the connection between the seismic box 142 and the connecting column 145. By setting the rubber ring 148, the sealing between the connecting column 145 and the seismic box 142 is improved. On the other hand, the rubber ring 148 is elastic and can provide space for the seismic box 142 to move under the influence of amplitude.

[0034] In an optional embodiment, the connecting column 145 is exposed inside the seismic box 142 and has fracture openings 149 on both the left and right sides. In small earthquakes, the micro-seismic anti-seismic mechanism 14 provides seismic resistance. When a large earthquake occurs during the use of the steel structure frame, since the connecting column 145 has fracture openings 149 on both the left and right sides of the upper end, when the amplitude exceeds the maximum deformation range of the connecting column 145, the connecting column 145 breaks at the fracture openings 149, thereby switching to the high-seismic anti-seismic mechanism 12 for seismic resistance. Automatic switching can be performed for different amplitudes.

[0035] In an optional embodiment, the support mechanism 20 includes a support mounting base 21 fixedly installed on the upper surface of the seismic mechanism 10. A column 22 is welded to the upper surface of the support mounting base 21, and a connecting groove 23 is provided on all four sides of the upper end of the column 22 to facilitate the installation of the support mechanism 20.

[0036] In an optional embodiment, the beam mechanism 30 includes a beam 31 disposed between two support mechanisms 20. Both sides of the beam 31 are provided with connecting bosses 32 that are adapted to the connecting grooves 23, so as to facilitate the connection and combination of the support mechanism 20 and the beam mechanism 30.

[0037] In an optional embodiment, threaded holes are provided on both the front and rear sides of the connecting boss 32, and through holes are provided on both sides of the connecting groove 23. The support mechanism 20 and the crossbeam mechanism 30 are connected by bolts, which facilitates installation and disassembly.
