Description

Technical Field

[0001] The utility model relates to the technical field of earthquake isolation, in particular to a cable device for controlling the tension and deformation of an earthquake isolation layer. Background Art

[0002] In the prior art, for example, in a tensile seismic isolation device based on high bearing capacity with the announcement number CN 117661742 A published on the Chinese patent website, a swing hydraulic cylinder is used as an important component of damping seismic isolation. However, the greater the damping seismic isolation force required for the entire building seismic isolation, the larger the model and overall weight of the hydraulic cylinder will be, which may reach several tons, which will increase the overall weight of the entire building, and the installation and maintenance costs are very high. In addition, when it is in action, since the force points are all at the hinge, this means that the hinge must bear most of the gravity of the entire hydraulic cylinder and have good rotation performance, making it difficult to achieve the preset seismic isolation damping effect.

[0003] In a cable-built-in tensile-resistance seismic isolation bearing with announcement number CN 215253627 U, the hinge points at both ends are installed inside the seismic isolation bearing, which is not only difficult to install but also difficult to maintain in the later stage. Once damage occurs, it is difficult to detect for a while. Utility Model Content

[0004] Based on the existing technical problems, the utility model proposes a cable device for controlling the tension and deformation of the seismic isolation layer.

[0005] The utility model proposes a cable device for controlling the tension and deformation of a seismic isolation layer, comprising a seismic isolation support connected between an upper building body and a lower building body, wherein structural beams and plates are fixedly installed on surfaces of the upper building body and the lower building body close to the seismic isolation support.

[0006] At least two steel sleeves located on the same vertical line are arranged on the structural beam and the plate through embedded holes, and a movable connection mechanism is arranged inside the steel sleeve. The movable connection mechanism includes anchor rods, and cables are fixedly installed at opposite ends of the two anchor rods. The cables are used to realize the tensile resistance and limiting actions between the upper building body and the lower building body.

[0007] Preferably, the inner wall of the embedded hole is in a T-stage shape, and the outer surface of the steel sleeve is matched with the inner wall of the embedded hole, and the steel sleeve is fixed integrally with the upper building body and the lower building body through embedded ribs.

[0008] Through the above technical solution, the steel sleeve can be connected with the upper building body and the lower building body as a whole, thereby increasing the overall force.

[0009] Preferably, a ball joint nut is rotatably sleeved on the top of the steel sleeve, and an end cover is fixedly mounted on the opposite end surface of the steel sleeve by bolts.

[0010] Through the above technical solution, the end cover can protect the ball joint nut and other structures inside the steel sleeve to prevent concrete from pouring into it and affecting subsequent maintenance work.

[0011] Preferably, a steel stiffening plate is also fixedly mounted on the inner bottom wall of the steel sleeve.

[0012] Through the above technical solution, the force on the inner bottom wall of the steel sleeve can be enhanced to prevent the ball joint nut from being stretched and displaced.

[0013] Preferably, a sealing cylinder is fixedly installed at the center of the ball of the ball joint nut and extends in the vertical direction of the diameter, and the anchor rod is fixedly installed at the axial center line of the inner wall of the sealing cylinder.

[0014] Through the above technical solution, the sealing tube can sleeve one end of the anchor rod connection into the steel sleeve to prevent the anchor rod from contacting and colliding with the steel sleeve when being stretched.

[0015] Preferably, the surface of the anchor rod is conical, and the small diameter end of the anchor rod is fixedly connected to the end surface of the cable.

[0016] Through the above technical solution, the use of a conical anchor rod can prevent the anchor rod from sliding out of the ball joint nut when being stretched.

[0017] Preferably, the cable is made of any one of carbon fiber cable, steel wire rope and steel strand, or any two of them in any ratio.

[0018] Through the above technical solution, the steel wire or carbon fiber has strong tensile properties, and the carbon fiber also has strong tensile properties, which can increase the amount of stretching of the cable during the earthquake resistance process, especially the amount of stretching during moderate to large earthquakes.

[0019] Preferably, when the cable is stretched to a maximum length or a maximum inclination angle, the bottom surface of the sealing cylinder does not contact the inner wall of the bottom end of the steel sleeve.

[0020] Through the above technical solution, such an arrangement can avoid the problem of excessive bending caused by the cable coming into contact with the inner wall of the sealing cylinder when being stretched.

[0021] The beneficial effects of the present invention are:

[0022] 1. By arranging at least two steel sleeves located on the same vertical line through embedded holes on the structural beams and plates, the steel sleeve can be connected to the entire structural beams and plates and the building body. By connecting the steel sleeve with concrete, the steel sleeve and the building body are completely connected as one, thereby increasing the stress on the entire steel sleeve and preventing the steel sleeve from displacement or slipping.

[0023] 2. By setting up a movable connection mechanism, the seismic isolation effect can be achieved when the cable is stretched at any angle, preventing the cable from being partially bent when being stretched for seismic isolation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Reference Figure 1-5 A cable device for controlling the tension and deformation of a seismic isolation layer includes a seismic isolation support 3 connected between an upper building body 1 and a lower building body 2, and structural beams and plates 4 are fixedly installed on the surfaces of the upper building body 1 and the lower building body 2 close to the seismic isolation support 3.

[0032] At least two steel sleeves 5 located on the same vertical line are cast through embedded holes on the structural beam and the plate 4. In order to obtain a larger force-bearing surface, the inner wall of the embedded hole is set in a T-stage shape, and the outer surface of the steel sleeve 5 is adapted to the inner wall of the embedded hole. The steel sleeve 5 is fixed integrally with the upper building body 1 and the lower building body 2 through embedded reinforcement. The steel sleeve 5 can be connected integrally with the upper building body 1 and the lower building body 2, thereby increasing the overall force.

[0033] By arranging at least two steel sleeves 5 located on the same vertical line through embedded holes on the structural beam and plate 4, the steel sleeve 5 can be connected to the entire structural beam and plate 4 and the building body. By connecting the concrete and the steel sleeve 5, the steel sleeve 5 and the building body are completely connected as one, thereby increasing the stress on the entire steel sleeve 5 and preventing the steel sleeve 5 from displacement or slipping.

[0034] In order to achieve the seismic isolation and damping effect at any angle, a movable connection mechanism is provided inside the steel sleeve 5, and the movable connection mechanism includes anchor rods 51. Cables 6 are fixedly installed at opposite ends of two anchor rods 51, and the cables 6 are used to achieve the tensile and limiting actions between the upper building body 1 and the lower building body 2.

[0035] Furthermore, a ball joint nut 52 is rotatably sleeved on the top of the steel sleeve 5, and an end cover 53 is fixedly installed on the opposite end face of the steel sleeve 5 by bolts. The end cover 53 can protect the ball joint nut 52 and other structures inside the steel sleeve 5 to prevent concrete from pouring into it and affecting the subsequent maintenance work.

[0036] In order to prevent the steel sleeve 5 from deforming due to stress, a steel stiffening plate 54 is fixedly installed on the inner bottom wall of the steel sleeve 5. The stress on the inner bottom wall of the steel sleeve 5 can be enhanced to prevent the ball joint nut 52 from being stretched and displaced.

[0037] The movable connection mechanism also includes a sealing cylinder 55 fixedly extending and installed along the vertical direction of the diameter at the ball center of the ball joint nut 52, and the anchor rod 51 is fixedly installed at the axis center line of the inner wall of the sealing cylinder 55. The sealing cylinder 55 can sleeve one end of the anchor rod 51 connected to the steel sleeve 5 to prevent the anchor rod 51 from contacting and colliding with the steel sleeve 5 when being stretched.

[0038] In order to prevent the anchor rod 51 from being pulled out, the surface of the anchor rod 51 is set to be conical, and the small diameter end of the anchor rod 51 is fixedly connected to the end surface of the cable 6. The conical anchor rod 51 can prevent the anchor rod 51 from slipping out of the ball joint nut 52 when being stretched.

[0039] In order to increase the tensile strength of the cable 6, the cable 6 is made of any one or two of carbon fiber cable, steel wire rope, and steel strand in any ratio. Steel wire or carbon fiber has strong tensile strength, and carbon fiber also has strong tensile strength, which can increase the amount of stretching of the cable 6 during seismic isolation, especially during moderate to severe earthquakes.

[0040] In order to prevent the steel sleeve 5 from colliding with the sealing sleeve 55, when the cable 6 is stretched to the maximum length or the maximum tilt angle, the bottom surface of the sealing sleeve 55 does not contact the inner wall of the bottom end of the steel sleeve 5. This arrangement can prevent the cable 6 from contacting the inner wall of the sealing sleeve 55 when being stretched, thereby preventing the problem of excessive bending.

[0041] like Figure 1 as well as Figure 3 As shown, when no vibration occurs, the cable 6 is in a relaxed state;

[0042] like Figure 4 As shown, when the building is at a medium earthquake displacement level, the cable 6 is just in a straightened state and begins to be stressed;

[0043] like Figure 5 As shown, when a large earthquake displacement occurs in the building, the cable 6 reaches the maximum stretched length, and at this time the cable 6 is stretched to the maximum length or the maximum tilt angle.

[0044] By providing a movable connection mechanism, the seismic isolation effect can be achieved when the cable 6 is stretched at any angle, thereby preventing the cable 6 from being partially bent when being stretched for seismic isolation.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
