[0022] The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings.

[0023] like Figure 1 As shown, the industrial plant hanging system includes a structural steel beam 1, a hanging connection steel plate 2, an energy dissipation and vibration damping sling 3, a purlin support connection steel plate 4, and a hanging steel beam 5. The top of the energy dissipation and vibration damping sling 3 is connected to the bottom of the structural steel beam 1 through the hanging connection steel plate 2, and the bottom of the energy dissipation and vibration damping sling 3 is connected to the hanging steel beam 5 through the purlin support connection steel plate 4.

[0024] like Figure 2 As shown, the structural steel beam 1 is fixed to the roof of the factory building, and multiple energy-dissipating and vibration-damping suspension cables 3 can be connected via hanging connecting steel plates 2, thereby reducing the stress on a single energy-dissipating and vibration-damping suspension cable 3. These multiple energy-dissipating and vibration-damping suspension cables 3 are evenly connected to the main trunk of the same hanger steel beam 5 via purlin support connecting steel plates 4. Both ends of the hanger steel beam 5 are embedded in the factory building walls. The two ends of the energy-dissipating and vibration-damping suspension cables 3 are perforated locking plates, which are fixed to the hanging connecting steel plates 2 and purlin support connecting steel plates 4 with high-strength bolts.

[0025] like Figure 3 As shown, the hanger steel beam 5 includes two cold-formed thin-walled C-shaped steels 51, and the purlin connecting steel plate 4 is an inverted T-shaped steel plate. The flange of the inverted T-shaped steel plate supports the lower flange of the two C-shaped steels. The web of the inverted T-shaped steel plate is inserted between the webs of the two C-shaped steels and extends out of the web for fixed connection with the energy dissipation and vibration reduction sling 3. The web of the inverted T-shaped steel plate and the back of the cold-formed thin-walled C-shaped steel 51 are fixedly connected by high-strength bolts to ensure the stability of the connection.

[0026] The aforementioned energy-dissipating and vibration-damping sling 3 is equipped with energy-dissipating and vibration-damping units 32. Under this structure, the sling system has sufficient rigidity and load-bearing capacity during normal use or minor earthquakes. Under strong earthquakes, the vibration-damping function of the energy-dissipating and vibration-damping units 32 on the energy-dissipating and vibration-damping sling 3 further improves the seismic performance and safety.

[0027] In practical applications, one or more energy dissipation and vibration damping units 32 are installed on the energy dissipation and vibration damping sling 3, or the energy dissipation and vibration damping unit 32 is fixed to one end of the energy dissipation and vibration damping sling 3, and the other end of the energy dissipation and vibration damping unit 32 is fixed to the hanger steel beam 5 or the connecting steel plate 2.

[0028] In this embodiment, an energy dissipation and vibration damping unit 32 is provided in the middle of the energy dissipation and vibration damping cable 3 as an example. Figure 4 As shown, the energy dissipation and vibration damping cable 3 includes an upper cable 31 and a lower cable 33. The energy dissipation and vibration damping unit 32 is located between the upper cable 31 and the lower cable 33. The upper cable 31, the lower cable 33 and the energy dissipation and vibration damping unit 32 are connected to the screw rod with a limit nut at the connection end. The other end of the screw rod is connected to the energy dissipation and vibration damping unit 32.

[0029] like Figure 5 As shown, the energy dissipation and vibration reduction unit 32 includes two L-shaped friction elements 321 and an inner U-shaped friction element 322. The two L-shaped friction elements 321 are located on the upper and lower sides of the inner U-shaped friction element 322, respectively, thus splicing together to form a U-shaped structure around the inner U-shaped friction element 322. The opening direction of the U-shaped structure is opposite to the opening direction of the U-shaped friction element 322. The spliced ​​U-shaped structure and U-shaped friction element 322 have through holes in the transverse direction (i.e., in the middle). The screws with limit nuts on the upper suspension cable 31 and lower suspension cable 33 pass through the transverse through holes of the U-shaped structure and U-shaped friction element 322 and are fixed.

[0030] Two L-shaped friction elements 321 and an inner U-shaped friction element 322 are provided with through holes in the vertical direction (the L-shaped friction element 321 has a round hole, and the U-shaped friction element 322 has a long groove-shaped channel). These three elements are connected by high-strength bolts in the vertical direction to provide preload. Simultaneously, a butterfly spring assembly 323 is fitted between the bolt nut and the L-shaped friction element. The contact surfaces of the U-shaped and L-shaped friction elements are a V-shaped concave surface and a corresponding V-shaped convex surface, respectively. When the upper sling 31 or lower sling 33 applies a large tension to the U-shaped structural component or the U-shaped friction element 322 through a screw with a limit nut, the long groove-shaped channel on the U-shaped friction element allows relative sliding between the U-shaped friction element and the U-shaped structural component.

[0031] When the hanger system is under normal use conditions or subjected to minor vibrations, the tension on the upper and lower slings 31 / 33 is small and does not exceed the slippage force of the energy dissipation and damping unit 32. The energy dissipation and damping unit 32 hardly undergoes relative slippage deformation. At this time, the energy dissipation and damping unit 32 and the upper and lower slings 31 / 33 work together to provide the initial stiffness and load-bearing capacity of the hanger system.

[0032] like Figure 6 , 7As shown, when the suspension system is subjected to a large-intensity earthquake, the tension on the upper and lower suspension cables 31 / 33 exceeds the sliding force of the energy dissipation and damping unit 32. The U-shaped friction element 322 and the L-shaped friction element 321 begin to slide relative to each other along the concave and convex contact surfaces to dissipate frictional energy. As the distance between the U-shaped friction element 322 and the L-shaped friction element 321 increases, the disc spring assembly 323 will undergo compression deformation, which increases the pressure between the U-shaped friction element 322 and the L-shaped friction element 321 to increase the frictional force.

[0033] When the tension on the energy dissipation and vibration damping unit 32 decreases or disappears, the elastic compressive force provided by the high-strength bolts will overcome the sliding friction between the U-shaped friction element 322 and the L-shaped friction element 321, so that each component in the energy dissipation and vibration damping unit 32 returns to its initial position and realizes the reset function.

[0034] The contact surface design of the L-shaped friction element 321 and the U-shaped friction element 322 maximizes the friction area to improve friction during relative sliding, thus helping to absorb and dissipate more energy. Meanwhile, the disc spring assembly 323 provides additional pressure between the U-shaped friction element 322 and the L-shaped friction element 321, increasing the damping effect.
