Description

Technical Field

[0001] This utility model is a shear vibration isolation device for recycled concrete, belonging to the field of building vibration isolation technology. Background Technology

[0002] When encountering earthquakes or strong winds, building structures are often susceptible to damage or significant deformation, affecting their normal use. To address this challenge, engineers typically employ shear isolation devices to adjust the building's vibration period. By dissipating vibration energy, they achieve vibration isolation, thereby effectively protecting the building structure. This technology generally involves installing isolation devices at the foundation or specific locations of the building, forming a seismic isolation layer that separates the superstructure from the foundation. This dissipates seismic energy and reduces the energy transmitted to the superstructure, thus more effectively ensuring the safety of the superstructure and its internal personnel and equipment.

[0003] Currently, shear vibration isolation devices mainly rely on spring systems to complete the vibration isolation task. However, vibration isolation devices are often located in underground environments, which puts the spring system under harsh conditions such as moisture for a long time, making it more susceptible to corrosion and wear, thus affecting the vibration isolation effect, overall quality and service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a recycled concrete shear vibration isolation device to solve the problems mentioned in the background. This invention provides sealed and concealed protection for the vibration isolation springs, effectively reducing the probability of damage to the springs due to external factors such as moisture, and effectively ensuring the vibration isolation effect, quality, and service life.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a recycled concrete shear vibration isolation device, comprising a lower plate, an inner constraint cylinder installed at the upper end of the lower plate, a vibration isolation block disposed at the middle of the upper end of the lower plate and located inside the inner constraint cylinder, an upper oil felt attached to the upper end of the vibration isolation block and attached to the upper end of the inner constraint cylinder, an upper plate installed at the upper end of the upper oil felt, an outer constraint cylinder disposed at the lower end of the upper plate and located outside the inner constraint cylinder, an upper oil felt disposed inside the outer constraint cylinder, a lower oil felt attached to the lower end of the outer constraint cylinder and located outside the inner constraint cylinder, and the lower oil felt mounted on the upper end of the lower plate;

[0006] An airbag is installed between the outer end of the inner constraint cylinder and the inner wall of the outer constraint cylinder, and the airbag is located between the lower and upper oil felts. An inner cylinder is installed inside the airbag facing the inner wall, and an outer cylinder is installed inside the airbag facing the outer wall, with the outer cylinder located outside the inner cylinder. Multiple vibration isolation springs are evenly arranged between the outer cylinder and the inner cylinder, and all of the multiple vibration isolation springs are located inside the airbag.

[0007] Furthermore, a constraint frame is installed at the middle of the upper end of the upper plate, and the outer end of the constraint frame is recessed inward to form multiple functional holes, which extend to the inner wall of the constraint frame.

[0008] Furthermore, the upper surface of the upper plate is recessed downward to form a plurality of first holes, and the first holes penetrate the upper plate. The first holes are located outside the constraint frame and outside the outer constraint cylinder.

[0009] Furthermore, the upper surface of the lower plate is recessed downward to form a plurality of second holes, and the second holes penetrate the lower plate. The second holes are located on the outside of the lower felt and are directly below the first holes.

[0010] Furthermore, the inner cylinder is equipped with first annular protective pads at both the upper and lower ends, and the two first annular protective pads are respectively attached to the top and bottom of the airbag. The outer cylinder is equipped with second annular protective pads at both the upper and lower ends, and the two second annular protective pads are respectively attached to the top and bottom of the airbag.

[0011] Furthermore, multiple reinforcing rods are evenly arranged at the upper end of the lower plate, and all of the reinforcing rods are located within the vibration isolation block.

[0012] Furthermore, the outer constraint cylinder, constraint frame, and vibration isolation block are all made of recycled concrete material, and the vibration isolation block contains randomly distributed short steel fibers.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a recycled concrete shear vibration isolation device, including a lower plate 4, an inner constraint cylinder 5 installed on the upper end of the lower plate 4, the lower plate 4 provides an installation carrier for components such as the inner constraint cylinder 5, and vibration isolation blocks 6, which are made of recycled concrete material and contain randomly distributed short steel fibers, are placed in the middle of the upper end of the lower plate 4. The vibration isolation blocks 6 support the upper plate 1 and other components. Multiple reinforcing rods 61 located in the vibration isolation blocks 6 are evenly placed on the upper end of the lower plate 4. The multiple reinforcing rods 61 work together to increase the strength of the vibration isolation blocks 6 themselves. Multiple second holes 41 are formed by recessing the upper end of the lower plate 4 downwards, penetrating the lower plate 4, located outside the lower felt 3 and directly below the first hole 11. The multiple second holes 41 work together to allow the lower plate 4 to be fastened.

[0025] The upper felt 8, which is attached to the upper end of the inner constraint cylinder 5 and located inside the outer constraint cylinder 2, is attached to the upper end of the vibration isolation block 6. The upper felt 8 provides waterproof performance. The upper plate 1 is installed on the upper end of the upper felt 8. The upper plate 1 provides an installation carrier for components such as the outer constraint cylinder 2. The outer constraint cylinder 2, which is located outside the inner constraint cylinder 5 and is made of recycled concrete material, is placed on the lower end of the upper plate 1. The outer constraint cylinder 2 protects components such as the airbag 7. The lower felt 3, which is located outside the inner constraint cylinder 5 and attached to the lower end of the outer constraint cylinder 2, is installed on the upper end of the lower plate 4. The lower felt 3 provides waterproof performance. Multiple first holes 11 are formed by recessing the upper end of the upper plate 1 downwards and are located outside the constraint frame 12 and outside the outer constraint cylinder 2. The multiple first holes 11 are used in combination to allow the upper plate 1 to be fastened.

[0026] An airbag 7 located between the lower roofing felt 3 and the upper roofing felt 8 is installed between the outer end of the inner constraint cylinder 5 and the inner wall of the outer constraint cylinder 2. The airbag 7 protects the inner cylinder 71 and other components and assists the vibration isolation performance of the vibration isolation spring 72. The inner cylinder 71 is placed inside the airbag 7 on the inner wall. The outer cylinder 73 located outside the inner cylinder 71 is installed inside the airbag 7 on the outer wall. The outer cylinder 73 works with the inner cylinder 71 to provide a mounting carrier for the vibration isolation spring 72. Two first annular protective pads 711, which are respectively attached to the top and bottom of the airbag 7, are installed on the upper and lower ends of the inner cylinder 71. The two first annular protective pads 711 work together to protect the airbag 7.

[0027] Two second annular protective pads 731, which are respectively attached to the top and bottom of the airbag 7, are respectively set on the upper and lower ends of the outer cylinder 73. The two second annular protective pads 731 work together to protect the airbag 7. Multiple vibration isolation springs 72 located inside the airbag 7 are evenly arranged between the outer cylinder 73 and the inner cylinder 71. The multiple vibration isolation springs 72 work together to achieve vibration isolation performance. Then, a constraint frame 12 made of recycled concrete material is installed on the upper middle part of the upper plate 1. The constraint frame 12 is used to shape the building column. Multiple functional holes 121 extending to the inner wall of the constraint frame 12 are formed by inward recessing on the outer end face of the constraint frame 12. The multiple functional holes 121 work together to add reinforcing steel bars.

[0028] During manufacturing, recycled concrete material is first used to solidify and form an outer constraint cylinder 2 on the lower end of the upper plate 1. Then, recycled concrete material is used to solidify and form a constraint frame 12 on the upper end of the upper plate 1. At the same time, recycled concrete material is poured into the inner constraint cylinder 5. During the pouring process, short steel fibers are spread into the inner constraint cylinder 5, thereby solidifying and forming a vibration isolation block 6 inside the inner constraint cylinder 5. Multiple reinforcing rods 61 on the lower plate 4 are located inside the vibration isolation block 6, thus giving the vibration isolation block 6 high strength and crack resistance. Then, the upper roofing felt 8 is installed on the lower end of the upper plate 1, and the installed upper roofing felt 8 is located inside the outer constraint cylinder 2. Then, the lower roofing felt 3 is set on the upper end of the lower plate 4, and the set lower roofing felt 3 is located outside the inner constraint cylinder 5.

[0029] Then, the airbag 7 is installed on the outer end of the inner constraint cylinder 5, and the inner constraint cylinder 5 is inserted into the outer constraint cylinder 2, so that the upper end of the vibration isolation block 6 contacts the upper roofing felt 8, and the lower end of the outer constraint cylinder 2 contacts the lower roofing felt 3, and the airbag 7 is located inside the outer constraint cylinder 2. Thus, it is manufactured using recycled concrete materials, which effectively reduces costs and energy consumption and has high economic and environmental benefits.

[0030] In use, the lower plate 4 is first fastened to the building foundation using the second hole 41 and the corresponding pre-reserved bolts and other fastening structures. Then, the upper plate 1 is fastened to the foundation using the first hole 11 and the corresponding bolts and other fastening structures. The reinforcing cage is then inserted into the constraint frame 12. The auxiliary reinforcing bars are then inserted into the constraint frame 12 through the functional hole 121. The auxiliary reinforcing bars are then tied to the reinforcing cage using steel wire. Concrete is used to solidify and form the building pile on the constraint frame 12. Building construction is then carried out on the foundation of the building pile.

[0031] At this time, the vibration isolation block 6 will support the building pile, while multiple vibration isolation springs 72 and airbags 7 will perform vibration isolation operations, thereby protecting the constructed building. Furthermore, the airbags 7 will install multiple vibration isolation springs 72 in a sealed space, achieving sealed and concealed protection for the vibration isolation springs 72, effectively reducing the probability of damage to the vibration isolation springs 72 due to external factors such as moisture, effectively ensuring the vibration isolation effect, quality and service life. In addition, the inner cylinder 71 and outer cylinder 73 inside the airbags 7 will isolate the vibration isolation springs 72 from the inner wall of the airbags 7, thereby protecting the airbags 7 and effectively reducing the probability of damage to the airbags 7.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
