Description

Technical Field

[0001] This utility model relates to the field of beam-column seismic technology, specifically a large-scale steel structure beam-column joint seismic energy dissipation device. Background Technology

[0002] Large-scale steel structure beam-column joints refer to the critical connections between beams and columns in large-scale steel structure buildings. These joints are crucial for ensuring the safety and reliability of multi-story and high-rise steel structures. The rationality of the joint design directly affects the structure's load-bearing capacity, safety, and overall stability. Joint design not only influences the structure's load-bearing capacity and safety but also directly impacts the quality of component fabrication and on-site installation. Large-scale steel structure beam-column joints utilize various connection methods, including fully welded connections, hybrid bolted-welded connections, and fully bolted connections.

[0003] In the application of existing large-scale steel structure beam-column joints, the beams and columns are fixed and rigidly connected, resulting in poor seismic performance and the inability to monitor the degree of vibration reduction. Therefore, it does not meet the current requirements. To address this, we propose a seismic energy dissipation device for large-scale steel structure beam-column joints. Utility Model Content

[0004] The purpose of this invention is to provide a seismic energy dissipation device for large-scale steel structure beam-column joints, in order to solve the problems mentioned in the background art, where existing large-scale steel structure beam-column joints have poor seismic performance and cannot monitor the degree of vibration reduction due to the fixed rigid connection between beams and columns.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-scale steel structure beam-column joint seismic energy dissipation device, comprising a supporting column, a damping connection mechanism, and an adapter connection mechanism. A damping connection mechanism is installed at the middle of both sides of the supporting column. One end of one of the damping connection mechanisms is equipped with an adapter connection mechanism, and one end of the adapter connection mechanism is equipped with a crossbeam. The damping connection mechanism includes a positioning mounting seat, which is fixedly connected to the supporting column. Multiple limiting diagonal strips are fixedly installed on the inner side of the bottom end of the positioning mounting seat. A connecting piece is fixedly installed at the bottom end of the positioning mounting seat. Multiple pressure sensors are installed on the upper surface of the connecting piece. Support sockets are installed on both sides of the positioning mounting seat, and multiple damping pads are provided at one end of each support socket.

[0006] The adapter connection mechanism includes a connecting crossbeam, and multiple supporting crossbeams are fixedly installed at one end of the connecting crossbeam near the positioning mounting seat. The multiple supporting crossbeams are arranged linearly.

[0007] Preferably, the connecting crossbar includes two connecting plates, and two supporting ribs are fixedly installed between the two connecting plates. One end of the lower surface of one of the connecting plates is provided with multiple positioning oblique protrusions.

[0008] Preferably, the crossbeam includes a beam body, and two reinforcing groove plates are installed on the inner side of the beam body near one end of the connecting crossbeam. One end of the beam body passes through the two reinforcing groove plates and is inserted between two supporting ribs. The two reinforcing groove plates are installed symmetrically relative to the beam body. The beam body, the connecting crossbeam, and the two reinforcing groove plates are fixedly connected by screws.

[0009] Preferably, the two support sockets are symmetrically installed relative to the positioning mounting base, the positioning mounting base is fixedly connected to both support sockets, both ends of the support plate are in contact with multiple shock-absorbing pads, one end of the support socket is inserted into the inner side of the shock-absorbing pad, and the positioning mounting base is fixedly connected to the multiple shock-absorbing pads through the two support sockets.

[0010] Preferably, both ends of the support plate are provided with waist-shaped holes, and screws are installed on the inner side of the waist-shaped holes. The support socket and the support plate are locked together by screws.

[0011] Preferably, the connecting piece is fixedly connected to multiple pressure sensors, the upper end of the pressure sensor passes through the positioning mounting base and the limiting inclined strip and is in contact with the lower end face of the positioning inclined protrusion, and the connecting plate and the positioning mounting base are slidably connected through multiple positioning inclined protrusions and the limiting inclined strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model connects the support socket and both ends of the support cross plate with shock-absorbing pads, locks the support cross plate and support socket with screws, and connects and fixes the connecting cross frame, beam and two reinforcing slot plates with screws. This allows the shock-absorbing connection mechanism and the adapter connection mechanism to quickly connect the support column and the cross beam of different lengths through the connecting cross frame of different lengths. During the connection of the support column and the cross beam, the positioning oblique protrusion is slidably limited by the limiting diagonal strip to reduce the axial displacement when the beam vibrates. At the same time, the shock-absorbing pads can provide vertical shock absorption for the connecting cross frame.

[0014] 2. This utility model uses a support socket for sliding support to prevent the connecting crossbeam from detaching from the positioning mounting seat, thereby improving the multi-directional stability and vibration reduction of the beam. Multiple pressure sensors are installed on the upper surface of the connecting piece, and the upper end of the pressure sensor passes through the positioning mounting seat and the limiting diagonal strip and is in close contact with the positioning diagonal protrusion. Thus, the pressure of the connecting crossbeam can be monitored through the pressure sensor, realizing real-time detection of the vibration intensity of the beam. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 This utility model provides an embodiment of a large-scale steel structure beam-column joint seismic energy dissipation device, including a supporting column 1, a shock-absorbing connection mechanism 2, and an adaptive connection mechanism 3. The shock-absorbing connection mechanism 2 is installed in the middle of both sides of the supporting column 1. The shock-absorbing connection mechanism 2 includes a positioning mounting seat 201, which is fixedly connected to the supporting column 1. A connecting piece 204 is fixedly installed at the bottom end of the positioning mounting seat 201. Multiple pressure sensors 206 are installed on the upper surface of the connecting piece 204. The connecting piece 204 is fixedly connected to the multiple pressure sensors 206. Multiple limiting inclined strips 205 are fixedly installed on the inner side of the bottom end of the positioning mounting seat 201. The limiting inclined strips 205 slide and limit the positioning inclined protrusion 305 to reduce the axial displacement of the beam 401 when it vibrates.

[0023] Support sockets 202 are installed on both sides of the positioning mounting base 201. The two support sockets 202 are symmetrically installed relative to the positioning mounting base 201. The positioning mounting base 201 is fixedly connected to the two support sockets 202. Each support socket 202 has multiple shock-absorbing pads 203 at one end. Both ends of the support cross plate 302 are in close contact with the multiple shock-absorbing pads 203. One end of the support socket 202 is inserted into the inner side of the shock-absorbing pad 203. The positioning mounting base 201 and the multiple shock-absorbing pads 203 are fixedly connected through the two support sockets 202. The shock-absorbing pads 203 can provide vertical shock absorption for the connecting cross frame 301 and provide sliding support through the support sockets 202.

[0024] Please see Figure 2 and Figure 4 One end of the shock-absorbing connection mechanism 2 is equipped with an adapter connection mechanism 3. The adapter connection mechanism 3 includes a connecting crossbeam 301. Multiple support crossbeams 302 are fixedly installed at one end of the connecting crossbeam 301 near the positioning mounting seat 201. The multiple support crossbeams 302 are arranged linearly. The support crossbeams 302 can enhance the end strength of the connecting crossbeam 301.

[0025] Please see Figures 3 to 5 The connecting crossbeam 301 includes two connecting plates 303, and two supporting ribs 304 are fixedly installed between the two connecting plates 303. One end of the lower surface of one of the connecting plates 303 is provided with multiple positioning oblique protrusions 305. Both ends of the supporting crossbeam 302 are provided with waist-shaped holes, and screws are installed on the inner side of the waist-shaped holes. The supporting socket 202 is locked to the supporting crossbeam 302 by screws. The upper end of the pressure sensor 206 passes through the positioning mounting seat 201 and the limiting oblique strip 205 and is in contact with the lower surface of the positioning oblique protrusion 305. The connecting plate 303 and the positioning mounting seat 201 are slidably connected by multiple positioning oblique protrusions 305 and limiting oblique strip 205. The pressure sensor 206 can monitor the pressure of the connecting crossbeam 301 and realize the real-time detection of the vibration intensity of the beam 401.

[0026] Please see Figure 2 and Figure 3 A crossbeam 4 is installed at one end of the adapter connecting mechanism 3. The crossbeam 4 includes a beam body 401. Two reinforcing groove plates 402 are installed on the inner side of the beam body 401 near the end of the connecting crossbeam 301. One end of the beam body 401 passes through the two reinforcing groove plates 402 and is inserted between the two support ribs 304. The two reinforcing groove plates 402 are installed symmetrically relative to the beam body 401. The beam body 401, the connecting crossbeam 301 and the two reinforcing groove plates 402 are fixedly connected by screws and slidably supported by the support socket 202 to prevent the connecting crossbeam 301 from detaching from the positioning mounting seat 201, thereby improving the multi-directional stability and vibration reduction operation of the beam body 401.

[0027] In use, two positioning mounting bases 201 are symmetrically fixedly installed on both sides of the support column 1. Then, the connecting crossbar 301 is inserted into the inner side of the positioning mounting base 201. Multiple limiting diagonal strips 205 are fixedly installed on the inner side of the bottom end of the positioning mounting base 201, so that multiple positioning diagonal protrusions 305 on the lower end face of the connecting plate 303 are in close contact with the limiting diagonal strips 205. At the same time, two symmetrically installed support sockets 202 are inserted through the positioning mounting base 201 and inserted into the lower part of the support crossbar 302, so that the two ends of the support sockets 202 and the support crossbar 302 are connected by shock-absorbing pads 203. The support crossbar 302 and the support sockets 202 are locked with screws.

[0028] The connecting crossbeam 301, beam 401, and two reinforcing slot plates 402 are fixed by screws, so that the connecting crossbeam 301 of different lengths can quickly connect the support column 1 and the beam 4 of different lengths through the shock-absorbing connecting mechanism 2 and the adapter connecting mechanism 3. During the connection of the support column 1 and the beam 4, the positioning oblique protrusion 305 is slidably limited by the limiting diagonal strip 205 to reduce the axial displacement of the beam 401 when it vibrates. At the same time, the shock-absorbing pad 203 can vertically dampen the connecting crossbeam 301, and the support socket 202 provides sliding support to prevent the connecting crossbeam 301 from separating from the positioning mounting seat 201, thereby improving the multi-directional stability and shock absorption operation of the beam 401.

[0029] Multiple pressure sensors 206 are installed on the upper surface of the connecting piece 204. The upper end of the pressure sensor 206 passes through the positioning mounting base 201 and the limiting inclined strip 205 and is in contact with the positioning inclined protrusion 305. Thus, the pressure of the connecting crossbeam 301 can be monitored through the pressure sensor 206, and the vibration intensity of the beam 401 can be detected in real time.
