Description

Technical Field

[0001] The present invention relates to a building isolation bearing, in particular to a pre-embedded tensile rubber isolation bearing. Background Art

[0002] Rubber isolation bearings are applied to various building structures, highway bridges and reinforcement structures. By alternately laminating and bonding multiple layers of steel plates and multiple layers of rubber, they have a series of advantages such as good horizontal performance, damping coefficient, vertical performance and vertical bearing capacity. However, such rubber isolation bearings have poor vertical tensile capacity. When the isolation bearing is in tension and enters the yield state, it is easy to cause the overall structure to overturn and fail.

[0003] Therefore, there is an urgent need for a rubber isolation bearing with strong vertical tensile capacity to solve the above problems. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the present invention provides a pre-embedded tensile rubber isolation bearing, which can improve the tensile capacity of the isolation bearing and solve the problem of tensile overturning of building structures. The technical solution adopted by the present invention is as follows:

[0005] A pre-embedded tensile rubber isolation bearing includes an isolation bearing body. At least one sliding space is provided inside the isolation bearing body. A cable is slidably arranged in the sliding space. One end of the cable extends to one side of the isolation bearing body and is connected with an elastic member. An embedded space communicating with the sliding space is provided on one side of the isolation bearing body. The elastic member is arranged in the embedded space, and the embedded space provides a vertical elastic deformation space for the elastic member.

[0006] Furthermore, a sleeve is arranged in the embedded space. The elastic member is arranged in the sleeve, and the sleeve can limit the movement track of the elastic member.

[0007] Furthermore, an upper joint is arranged at one end of the cable. The upper joint is connected to the isolation bearing body to fix one end of the cable.

[0008] Furthermore, a first guide sleeve is arranged on the isolation bearing body. One end of the first guide sleeve communicates with the sliding space. The upper joint is arranged at the other end of the first guide sleeve, and the first guide sleeve can prevent the upper joint from moving towards the isolation bearing body.

[0009] Furthermore, an upper connecting plate is arranged at the other end of the isolation bearing body. The upper joint is arranged on the upper connecting plate, and the first guide sleeve is arranged between the upper connecting plate and the isolation bearing body.

[0010] Furthermore, a lower joint is arranged at the other end of the cable. The lower joint can prevent the elastic member from detaching from the other end of the cable.

[0011] Furthermore, a second guide sleeve is provided on the isolation bearing body. The second guide sleeve communicates the sliding space and the embedded space, and the cable passes through the second guide sleeve.

[0012] Furthermore, a lower connecting plate is provided at one end of the isolation bearing body, and the second guide sleeve is arranged on the lower connecting plate.

[0013] Furthermore, a pre-embedded part is also arranged in the embedded space. One end of the pre-embedded part is connected to the lower connecting plate, and the other end of the pre-embedded part is provided with a anchor bolt.

[0014] Furthermore, an opening penetrating the pre-embedded part is provided on the pre-embedded part, and the sleeve is arranged in the opening.

[0015] Advantages of the present invention:

[0016] When the isolation bearing body of the present application has an extreme horizontal displacement, an upward tensile stress is generated, so that the cable drives the elastic member to elastically deform in the embedded space to resist the tensile stress, thereby restricting the displacement of the isolation bearing body in the vertical direction and playing a role in anti-tensile and anti-overturning;

[0017] The elastic member recovers its deformation while the isolation bearing body recovers its deformation, playing a role in rebounding the cable, helping the cable to reset, and preventing the stuck phenomenon that occurs when the cable itself recovers;

[0018] The cable and the elastic member are hidden in the embedded space, improving the concealment and corrosion resistance, and being beneficial to extending the service life. Description of the drawings

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Please refer to the attached Figure 1, the present invention provides a pre-embedded tensile rubber isolation bearing, which includes an isolation bearing body 1. At least one sliding space is provided inside the isolation bearing body 1. A cable 2 is slidably arranged in the sliding space. One end of the cable 2 extends to one side of the isolation bearing body 1 and is connected to an elastic member 4. An embedded space communicating with the sliding space is provided on one side of the isolation bearing body 1. The elastic member 4 is arranged in the embedded space, and the embedded space provides a vertical elastic deformation space for the elastic member 4.

[0024] In this application, the number of sliding spaces is determined after balancing and checking according to mechanical properties and the size of the drilled hole space, and can be 2, 4, 6 or more.

[0025] In this application, the length of the cable 2 is not less than the length of the sliding space when the isolation bearing body 1 is not deformed; the length of the cable 2 is preferably the length of the sliding space when the isolation bearing body 1 generates the ultimate horizontal displacement under earthquake.

[0026] In this application, the elastic member 4 is a rubber member or a spring member, and is used in series or parallel according to needs; the elastic member 4 plays a role in buffering the instantaneous horizontal impact force and vertical tensile stress when the isolation bearing body 1 generates the ultimate displacement, and when the isolation bearing body 1 recovers from deformation, it can also play a role in rebounding the cable 2, thus avoiding the jamming phenomenon when the cable 2 restores its own state.

[0027] Please refer to the appendix Figure 2 , when the isolation bearing body has a horizontal ultimate displacement, an upward tensile stress is generated. At this time, a part of the cable 2 slides in the sliding space, and the other part drives the elastic member 4 to slide in the embedded space until the elastic member 4 moves to the top of the embedded space and generates elastic deformation to offset the generated tensile stress, thereby restricting the relative displacement of the isolation bearing body 1 in the vertical direction and playing a role in anti-tensile and anti-overturning; at the same time, both the cable 2 and the elastic member 4 are hidden in the embedded space. After the isolation bearing body 1 is installed, both the cable 2 and the elastic member 4 are in a hidden state and are not exposed outside the isolation bearing body 1, and the concealment performance and anti-corrosion performance are more remarkable.

[0028] In this application, a sleeve 3 is arranged in the embedded space. The elastic member 4 is arranged in the sleeve 3, and the sleeve 3 can limit the movement track of the elastic member 4; the extending direction of the sleeve 3 is preferably the same as the extending direction of the sliding space, so that the cable 2 is in a natural straight state when the isolation bearing body 1 is not deformed.

[0029] In this application, an upper joint 201 is arranged at one end of the cable 2, and the upper joint 201 is connected to the isolation bearing body 1 to fix one end of the cable 2.

[0030] In this application, a first guide sleeve 5 is provided on the seismic isolation bearing body 1. One end of the first guide sleeve 5 is in communication with the sliding space, and the upper joint 201 is arranged at the other end of the first guide sleeve 5. The first guide sleeve 5 can prevent the upper joint 201 from moving towards the seismic isolation bearing body 1. The first guide sleeve 5 provides a guiding and limiting function for the cable 2, facilitating the installation of the cable 2 and also avoiding direct contact between the cable 2 and the seismic isolation bearing body 1, thereby improving the service life of the cable 2.

[0031] In this application, an upper connecting plate 6 is arranged at the other end of the seismic isolation bearing body 1, the upper joint 201 is arranged on the upper connecting plate 6, and the first guide sleeve 5 is arranged between the upper connecting plate 6 and the seismic isolation bearing body 1. The design of the upper connecting plate 6 can connect the seismic isolation bearing body 1 with the building structure, providing an installation carrier for the seismic isolation bearing body 1.

[0032] Specifically, the first guide sleeve 5 can be directly arranged on the seismic isolation bearing body 1 or on the upper connecting plate 6, both of which can play a role in guiding the movement and reducing the wear of the cable 2.

[0033] To improve the lubricity of the cable 2, silicone oil can be applied to the surface of the cable 2. Thus, when the seismic isolation bearing body 1 generates a horizontal displacement, the movement of the cable 2 in the sliding space is not restricted, and it will not hinder the horizontal displacement deformation of the seismic isolation bearing body 1, thereby reducing the damage to the building. And when the seismic isolation bearing body 1 recovers from the deformation, the self-lubricity of the cable 2 also facilitates its own recovery to the original state.

[0034] In this application, a lower joint 202 is arranged at the other end of the cable 2. The lower joint 202 can prevent the elastic member 4 from detaching from the other end of the cable 2. The cross-sectional shape of the lower joint 202 is T-shaped, and the diameter of one end thereof is larger than the aperture on the elastic member 4 for inserting the cable 2, so that the cable 2 is always in a connected state with the elastic member 4.

[0035] In this application, a second guide sleeve 7 is provided on the seismic isolation bearing body 1. The second guide sleeve 7 communicates the sliding space and the embedded space, and the cable 2 passes through the second guide sleeve 7. The second guide sleeve 7 plays a role in guiding the movement, avoiding direct friction between the cable 2 and the seismic isolation bearing body 1 and accelerating wear, which is beneficial to improving the service life of the cable 2.

[0036] In this application, a lower connecting plate 8 is arranged at one end of the seismic isolation bearing body 1, and the second guide sleeve 7 is arranged on the lower connecting plate 8. The lower connecting plate 8 provides an installation carrier for the seismic isolation bearing body 1.

[0037] Specifically, the second guide sleeve 8 can be directly arranged on the seismic isolation bearing body 1 or on the lower connecting plate 8, both of which can play a role in guiding the movement and reducing the wear of the cable 2.

[0038] In the present application, a pre-embedded member 9 is further provided in the pre-embedded space. One end of the pre-embedded member 9 is connected to the lower connecting plate 8, and an anchor bolt 10 is provided at the other end of the pre-embedded member 9. The pre-embedded member 9 and the anchor bolt 10 can be separated from and connected to the isolation bearing body 1. In actual use, the pre-embedded member 9 and the anchor bolt 10 are pre-placed in the concrete. After the pre-embedded member 9 is fixed, it is connected to the lower connecting plate 8 to complete the overall layout of the isolation bearing.

[0039] In the present application, an opening penetrating through the pre-embedded member 9 is provided on the pre-embedded member 9, and the sleeve 3 is arranged in the opening. The connection between the sleeve 3 and the pre-embedded member 9 facilitates the overall pre-embedding operation of the pre-embedded member 9 and reduces the labor intensity.

[0040] In summary, the present application has good vertical tensile and anti-overturning effects, remarkable concealment performance and anti-corrosion performance, is convenient for resetting, and reduces the probability of jamming when the cable itself recovers.

[0041] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
