[0002] High-efficiency seismic-resistant steel structures possess high strength, lightweight, good ductility and toughness, making them suitable for high-rise buildings, bridges, and other engineering projects. Through ductile design, energy dissipation devices, and rational structural layout, they can effectively absorb seismic energy and ensure structural safety. Common systems include frame structures, braced frames, and buckling-restrained braces, which, combined with seismic isolation and damping technologies, further enhance seismic performance. Utility Model Content
[0003] The purpose of this invention is to provide a high-efficiency earthquake-resistant steel structure to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency earthquake-resistant steel structure, comprising an outer constraint steel plate, a slot A, an arc-shaped energy-dissipating cover A, a reset slot, an energy-dissipating groove A, an extrusion part A, a sliding steel plate, a sliding groove, and a pre-tightening bolt group. The upper part of the inner end of the outer constraint steel plate has a slot A. The arc-shaped energy-dissipating cover A is fixed to the lower side of the slot A. The reset slot is opened in the middle of the inner end of the outer constraint steel plate. The energy-dissipating groove A is opened in the lower part of the inner end of the outer constraint steel plate. The extrusion part A is fixed to the lower side of the energy-dissipating groove A. The sliding steel plate is installed between the front and rear outer constraint steel plates. The sliding groove is opened at both ends of the outer constraint steel plate. The pre-tightening bolt group installs the sliding steel plate on the outer constraint steel plate through the sliding groove.
[0005] Based on the above technical solution, the sliding steel plate includes a plate body, an extrusion part B, an energy-consuming groove B, a protrusion, an arc-shaped energy-consuming cover B, a slot B, and bolt holes. The extrusion part B is fixed to the upper part of both the front and rear ends of the plate body, and the extrusion part B corresponds to the slot A. The energy-consuming groove B is opened at the lower part of the extrusion part B, and the energy-consuming groove B corresponds to the arc-shaped energy-consuming cover A. The protrusion is fixed to the middle part of both the front and rear ends of the plate body, and the protrusion corresponds to the reset groove. The arc-shaped energy-consuming cover B is fixed to the lower part of both the front and rear ends of the plate body, and the arc-shaped energy-consuming cover B corresponds to the energy-consuming groove A. The slot B is opened on the lower side of the arc-shaped energy-consuming cover B, and the slot B corresponds to the extrusion part A. The bolt holes are opened at both the front and rear ends of the plate body.
[0006] Based on the above technical solution, the pre-tightening bolt group is fixed to the plate body through bolt holes.
[0007] Compared with the prior art, the present invention has the following advantages: The present invention has an energy-dissipating groove and a fixed arc-shaped energy-dissipating cover in the friction damper formed by the outer constraint steel plate and the sliding steel plate. When facing vibration, the friction and sliding of the outer constraint steel plate and the sliding steel plate utilize the deformation of the arc-shaped energy-dissipating cover to absorb energy and resist vibration.

Detailed Implementation
[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0014] like Figures 1 to 4 As shown, a high-efficiency seismic-resistant steel structure includes an outer constraint steel plate 1, a slot A2, an arc-shaped energy-dissipating cover A3, a reset slot 4, an energy-dissipating slot A5, an extrusion part A6, a sliding steel plate 7, a sliding groove 8, and a pre-tightening bolt group 9. The outer constraint steel plate 1 has a slot A2 at its upper inner end. The arc-shaped energy-dissipating cover A3 is fixed to the lower side of the slot A2. The reset slot 4 is located at the middle of the inner end of the outer constraint steel plate 1. The energy-dissipating slot A5 is located at the lower inner end of the outer constraint steel plate 1. The extrusion part A6 is fixed to the lower side of the energy-dissipating slot A5. The sliding steel plate 7 is installed between the front and rear outer constraint steel plates 1. The sliding groove 8 is opened at both ends of the outer constraint steel plate 1. The pre-tightening bolt group 9 is installed on the outer constraint steel plate 1 through the sliding groove 8.
[0015] The sliding steel plate 7 includes a plate body 10, an extrusion section B11, an energy-consuming groove B12, a protrusion 13, an arc-shaped energy-consuming cover B14, a slot B15, and bolt holes 16. The extrusion section B11 is fixed to the upper part of both the front and rear ends of the plate body 10, and the extrusion section B11 corresponds to the slot A2. The energy-consuming groove B12 is opened at the lower part of the extrusion section B11, and the energy-consuming groove B12 corresponds to the arc-shaped energy-consuming cover A3. The protrusion 13 is fixed to the middle part of both the front and rear ends of the plate body 10, and the protrusion 13 corresponds to the reset groove 4. The arc-shaped energy-consuming cover B14 is fixed to the lower part of both the front and rear ends of the plate body 10, and the arc-shaped energy-consuming cover B14 corresponds to the energy-consuming groove A5. The slot B15 is opened on the lower side of the arc-shaped energy-consuming cover B14, and the slot B15 corresponds to the extrusion section A6. The bolt holes 16 are opened at both the front and rear ends of the plate body 10.
[0016] The pre-tightening bolt group 9 is fixed to the plate 10 through the bolt holes 16.
[0017] The working principle of this utility model is as follows: When vibration occurs, the pre-tightened bolt group 9, under the constraint of the sliding groove 8, causes the sliding steel plate 7 and the outer constraint steel plate 1 to move relative to each other vertically. The protrusion 13 presses against the reset groove 4, widening the distance between the sliding steel plate 7 and the outer constraint steel plate 1. When the arc-shaped energy-dissipating cover A3 of the outer constraint steel plate 1 slides out of the energy-dissipating groove B12, it contacts the pressing part B11. The pressing part B11 compresses the arc-shaped energy-dissipating cover A3, causing it to deform and absorb energy. When the arc-shaped energy-dissipating cover B14 of the plate body 10 slides out of the energy-dissipating groove A5, it contacts the pressing part A6. The pressing part A6 compresses the arc-shaped energy-dissipating cover B14, causing it to deform and absorb energy. After the vibration ends, the reset groove 4 presses the protrusion 13 back to its original position. This achieves efficient vibration resistance.
[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
