Description

Technical Field

[0001] This invention relates to the field of building vibration reduction technology, and more specifically, to an adaptive vibration reduction connection device and its application. Background Technology

[0002] Beam-column joints are critical components of building frame structures. The core area of ​​these joints experiences complex stress conditions, bearing both the compressive stress from the columns and the bending moments from the beam and column ends. Under repeated seismic loads, the core area is under combined shear and compressive stress, often leading to intersecting cracks and column end damage. Corner and edge columns, in particular, experience even more complex stresses due to torsion and eccentricity, making them more susceptible to seismic damage than inner columns. Therefore, installing damping devices at beam-column joints is essential for building earthquake resistance.

[0003] Existing beam-column joint energy dissipation structures typically dissipate seismic energy through angle steel deformation and bolt friction to reduce residual deformation at the beam-column joint. However, this method of energy dissipation through steel plate deformation and friction is insufficient to achieve ideal vibration reduction effects. Therefore, it is necessary to provide a novel adaptive vibration reduction connection device. Summary of the Invention

Several blocking parts are provided in the sliding groove along its sliding direction, and energy dissipation parts corresponding to the blocking parts are symmetrically arranged on both sides of the slider. During operation, the slider slides in the sliding groove, and the energy dissipation parts and the blocking parts rub and squeeze against each other to achieve the energy dissipation function.

[0015] This application also discloses the application of an adaptive damping connection device in the field of damping of L-shaped, T-shaped and cross-shaped beam-column joints.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention features an energy-dissipating box mounted on a crossbeam. Inside the energy-dissipating box is an upward-opening chute containing a slider. An arc-shaped connecting plate is fixed to the top of the slider, and the other end of the arc-shaped connecting plate is fixedly connected to a vertical column via bolts. Several elastic spherical blocks are arranged on both sides of the chute along the sliding direction, and rigid spherical blocks are arranged on both sides of the slider. Springs are arranged around the elastic spherical blocks, with the inner diameter of the springs smaller than the diameter of the elastic spherical blocks. When the rigid spherical blocks compress the elastic spherical blocks, the springs deform. During deformation, the inner circumference of the springs and the elastic spherical blocks come into contact, rubbing and compressing each other. Compared to ordinary spring-based shock absorption and energy dissipation, this invention significantly improves the shock absorption and energy dissipation effect.

[0018] 2. This invention features an energy-dissipating box mounted on a crossbeam. Inside the energy-dissipating box is an upward-opening chute containing a slider. An arc-shaped connecting plate is fixed to the top of the slider, and the other end of the arc-shaped connecting plate is fixedly connected to a vertical column via bolts.

Top rods are symmetrically positioned on both sides of the slider, with the end of the top rod away from the slider abutting against the piston plate. The piston boxes are filled with hydraulic oil. A connecting channel is provided on the functional box, connecting the piston boxes and the spherical bags. When the rigid spherical blocks compress the spherical bags, the hydraulic oil inside the bags enters the piston box through the connecting channel. At this time, the top rods also compress the piston plate. The compressive force of the rigid spherical blocks is transmitted to the piston plate via the hydraulic oil and then to the slider via the top rods. The hydraulic oil's temperature rises after compression, converting seismic energy into internal hydraulic energy, thus greatly achieving the energy dissipation effect. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] As shown in the figure, this invention discloses an adaptive vibration damping connection device, including an energy dissipation component. A receiving groove is provided on a crossbeam 2, and the energy dissipation component is fixedly installed within the receiving groove. The energy dissipation component includes an energy dissipation box 3, which has an upward-opening sliding groove 4. A slider 5 adapted to the sliding groove 4 is installed within the sliding groove 4, and the top of the slider 5 is fixedly connected to a vertical column 1. Several blocking parts are symmetrically arranged on both sides of the sliding groove 4 along its sliding direction. Energy dissipation parts corresponding to the blocking parts are symmetrically arranged on both sides of the slider 5. In its natural state, the slider 5 is located in the middle of the sliding groove 4. At this time, the structures on the left and right sides of the sliding groove 4 are identical and symmetrical. During an earthquake, regardless of whether the vertical column 1 drives the slider 5 to slide left or right within the sliding groove 4, the energy dissipation parts can rub against and compress the blocking parts, effectively achieving the vibration damping and energy dissipation function. To obtain a better energy dissipation effect, the spacing between the blocking parts should be minimized.

[0027] During an earthquake, relative movement occurs between the horizontal beam 2 and the vertical column 1. The vertical column 1 drives the slider 5 to slide within the groove 4. The energy dissipation part and the blocking part come into contact, rub, and compress against each other, continuously consuming and converting energy, transforming kinetic energy into internal energy and dissipating it outwards, greatly improving the vibration reduction and energy dissipation effect between the beam and the column. Compared with existing technologies that dissipate seismic energy through angle steel deformation and bolt friction, the blocking part can return to its original shape after the compressive force disappears, allowing for repeated use and improving equipment utilization.

[0028] It should be noted that the blocking part is made of a material with elastic properties, such as rubber; or, the blocking part is another structure that deforms under force and returns to its original shape when the force is removed. In order to enable better friction and compression between the blocking part and the energy dissipation part, the contact surface between the blocking part and the energy dissipation part is set as an arc-shaped surface, such as both the blocking part and the energy dissipation part being spherical.

[0029] One embodiment of the blocking part and the energy dissipation part is as follows: Figure 5 As shown, the blocking part is an elastic ball block 6, and the energy dissipation part is a rigid ball block 7. When an earthquake occurs, the slider 5 slides in the groove 4, and the rigid ball block 7 continuously squeezes and rubs against the elastic ball block 6, converting the earthquake energy into frictional heat energy and elastic energy; when the earthquake disappears, the elastic ball block 6 returns to its original shape under its own rebound force, making it convenient for the next use.

[0030] To further improve the energy dissipation effect, a spring is provided around the elastic sphere 6. Figure 5 The spring portion is not shown, and the inner diameter of the spring is smaller than the diameter of the elastic ball block 6. When the rigid ball block 7 compresses the elastic ball block 6, the spring deforms. During the deformation process, the inner circumference of the spring and the elastic ball block 6 form mutual contact friction and compression, which greatly improves the shock absorption and energy dissipation effect compared to ordinary spring shock absorption and energy dissipation.

[0031] Another embodiment of the blocking part and the energy dissipation part is, as follows: Figure 3 As shown, the blocking part is a spherical bag 15 filled with hydraulic oil, and the energy dissipation part is a rigid ball block 7. During an earthquake, the slider 5 slides within the groove 4, the rigid ball block 7 continuously squeezes and rubs against the spherical bag 15, and the elastic ball block 6 compresses the hydraulic oil, converting the earthquake energy into frictional heat energy and the internal energy of the hydraulic oil. When the earthquake subsides, the spherical bag 15 returns to its original shape under the action of the internal energy of the hydraulic oil, making it convenient for the next use.

[0032] To further improve the seismic energy dissipation effect, piston boxes 8 are symmetrically arranged at both ends of the slide groove 4. A piston plate 9 adapted to the piston box 8 is slidably arranged inside the piston box 8. One end of the piston box 8 is open and a baffle 10 is provided at its end. The baffle 10 is used to restrict the piston plate 9 from sliding out of the piston box 8. The cavity formed by the piston plate 9 and the piston box 8 is filled with hydraulic oil. A sealing ring 16 is provided around the piston plate 9 to prevent the hydraulic oil from flowing out of the piston box 8. Push rods 11 are symmetrically arranged at both ends of the slider 5. The push rods 11 abut against the piston plate 9. In the natural state, the slider 5 is located in the middle of the slide groove 4.

[0033] During an earthquake, the vertical column 1 drives the slider 5 to slide to the left within the groove 4. The energy dissipation part rubs against and compresses the blocking part. At the same time, the push rod 11 compresses the piston plate 9. The piston plate 9 slides to the left within the piston box 8, compressing the hydraulic oil. The temperature of the hydraulic oil rises, converting the seismic energy into the internal energy of the hydraulic oil. The vertical column 1 then drives the slider 5 to slide to the right within the groove 4. The energy dissipation part rubs against and compresses the blocking part. The push rod 11 on the left side moves away from the piston plate 9 on the left side. Under the action of the hydraulic oil, the piston plate 9 slowly moves to the right. When the slider 5 moves to the middle of the groove 4, the push rod 11 on the right side compresses the piston plate 9 on the right side. The piston plate 9 slides to the right within the piston box 8, compressing the hydraulic oil on the right side. The temperature of the hydraulic oil rises, converting the seismic energy into the internal energy of the hydraulic oil. This process is repeated to achieve the purpose of seismic energy dissipation.

[0034] It should be noted that the blocking parts inside the slide 4 are divided into four groups, with adjacent groups arranged symmetrically. For example, the two groups of blocking parts on the left side of the slide 4 are symmetrical in the length direction of the slide 4, and the two groups of blocking parts on the left and right sides at the front of the slide 4 are symmetrical in the width direction of the slide 4.

[0035] To further improve the energy dissipation effect, the energy dissipation box 3 is provided with four sets of connecting channels 17. One end of each connecting channel 17 is connected to the piston box 8, and the other end is connected to a corresponding set of spherical bags 15. By setting the connecting channels 17, the piston box 8 can be connected to a set of multiple spherical bags 15. When the rigid ball block 7 squeezes the spherical bags 15 on the front and rear sides, the hydraulic oil in these two spherical bags 15 enters the piston box 8 through the connecting channels 17. At this time, the push rod 11 also squeezes the piston plate 9. The squeezing force of the rigid ball block 7 is transmitted to the piston plate 9 through the hydraulic oil, and then to the slider 5 through the push rod 11, which greatly improves the energy dissipation effect. It should be noted that the maximum filling volume of the spherical bags 15 is fixed.

[0036] In one embodiment of the present invention, a weight 18 is provided inside the piston plate 9. The weight 18 is made of a high-density metal or alloy. The slider 5 drives the push rod 11 to move, and the push rod 11 pushes the piston plate 9. Because the piston plate 9 is filled with a high-density weight 18, the seismic energy is converted into work done by pushing the weight 18, which further improves the seismic energy dissipation effect.

[0037] Based on the number of beams and columns at the joint, the joints of building frame structures are divided into three types: L-shaped, T-shaped, and cross-shaped. The damping connection device disclosed in this application can be used for all three types. It is installed on the outside of the beam-column joint, and the damping connection device can be installed at each right angle of the beam-column joint. Figure 1 As shown, the damping connection device includes an arc-shaped connecting plate 13. One end of the arc-shaped connecting plate 13 is fixedly connected to the vertical column 1 by multiple fixing bolts 14, and the other end is fixedly connected to the top of the slider 5. By setting the arc-shaped connecting plate 13, the connection strength of the beam-column joint can also be increased. Figure 2 The central arc-shaped connecting plate is not fully shown.

[0038] In one embodiment of the present invention, friction plates 12 are provided on both sides of the top of the slider 5 along its sliding direction, and the lower surface of the friction plates 12 contacts the upper surface of the energy dissipation box 3. When the slider 5 slides in the groove 4, the friction plates 12 rub against the upper surface of the energy dissipation box 3, converting the seismic energy into frictional heat energy for dissipation.

[0039] When this damping connection device is used for T-beam-column joints, it can be installed inside the beam-column joint. In this case, the damping connection device is fixedly installed on the top of the vertical column, such as... Figure 4 As shown.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
