Description

Technical Field

[0001] The utility model relates to the technical field of earthquake isolation, and more particularly to a buffer-type tensile device for construction. Background Art

[0002] Seismic isolation technology employs a flexible connection between the building's superstructure and foundation, creating a sufficiently safe seismic isolation system. Due to the isolation and shock absorption properties of the isolation layer, the superstructure undergoes approximately horizontal movement during an earthquake, effectively isolating the structure from the impact. This technology not only mitigates damage to the superstructure but also effectively protects the building's interior furnishings and furnishings. In practice, seismic isolation technology is being adopted in an increasing number of buildings.

[0003] In recent years, seismic isolation technology has been gradually applied to high-rise and super-high-rise buildings. When an earthquake occurs, there will be horizontal forces, and the upper buildings will tend to topple, which will then generate an upward pulling force. This causes the seismic isolation structure of the seismic isolation layer to be subjected to axial tension, which in turn affects the performance of the seismic isolation structure. To solve this problem, a tensile device is generally designed in the seismic isolation layer of the building to withstand the overturning moment generated during an earthquake. Currently available tensile devices are generally in the form of slides and guide rails, or the middle part of the tensile device uses a threaded connection structure for tensile resistance. This type of tensile device has the disadvantages of high cost and complex structure.

[0004] Therefore, how to develop a buffer-type tensile device that can overcome the above-mentioned defects of the tensile device in the prior art is a problem that those skilled in the art urgently need to solve. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 2The embodiment of the utility model discloses a buffer-type tensile device for construction, comprising: an upper connecting plate 1, a lower connecting plate 11, an upper connecting member 4, a lower connecting member 8, a tensile member 5 and a rubber member.

[0027] The upper connecting plate 1 and the lower connecting plate 11 are spaced apart. The upper connecting plate 1 and the lower connecting plate 11 are connected to the building structure respectively, and the connection adopts anchor bolt connection or other connection methods.

[0028] One end of the upper connecting member 4 is connected to the upper connecting plate 1 through the upper tensile plate 3 , and the other end of the upper connecting member 4 is provided with a first connecting portion. The connecting position of the upper tensile plate 3 and the upper connecting plate 1 is provided with a first friction pair 2 .

[0029] One end of the lower connecting member 8 is connected to the lower connecting plate 11 via the lower tensile plate 9. The other end of the lower connecting member 8 is provided with a second connecting portion. The connection between the lower tensile plate 9 and the lower connecting plate 11 is provided with a second friction pair 10. Preferably, both the first connecting portion and the second connecting portion are annular structures. The annular structure facilitates connection with the tensile member 5. In other embodiments, the first connecting portion and the second connecting portion may also adopt a hook-shaped structure or other structure as the connecting portion, as long as they can be hooked or connected to the tensile member 5.

[0030] The tensile member 5 is disposed between the upper connecting plate 1 and the lower connecting plate 11. One end of the tensile member 5 is connected to the first connecting portion, and the other end is connected to the second connecting portion. A gap exists between the tensile member 5 and both the first and second connecting portions. The tensile member 5 is made of metal steel and can be a steel structure that meets tensile strength requirements, such as a chain link or a steel wire rope.

[0031] The rubber member is coated on the outside of the tensile member 5 , and the gap is also filled with the rubber member.

[0032] It should be noted that: during use, the buffer-type tensile device for buildings provided by the present invention connects the upper connecting plate 1 to the building that needs to be isolated from the earthquake, and connects the lower connecting plate 11 to other buildings below the building. An upper tensile plate 3 is provided on the upper connecting plate 1. The upper tensile plate 3 and the upper connecting plate 1 are in a planar clamping structure. A first friction pair 2 is provided at the position where the upper tensile plate 3 is connected to the upper connecting plate 1. The upper tensile plate 3 is used to install the upper connecting member 4. Similarly, a lower tensile plate is provided on the lower connecting plate 11. 9. The lower tensile plate 9 and the lower connecting plate 11 are of a planar clamping structure. A second friction pair 10 is provided at the position where the lower tensile plate 9 and the lower connecting plate 11 are connected. The lower tensile plate 9 is used to install the lower connecting member 8. The upper connecting member 4 is provided with a first connecting portion, and the lower connecting member 8 is provided with a second connecting portion. A tensile member 5 is connected between the upper connecting member 4 and the lower connecting member 8. Specifically, one end of the tensile member 5 is connected to the first connecting portion, and the other end of the tensile member 5 is connected to the second connecting portion. The outside of the tensile member 5 is covered with a rubber member. With such an arrangement, when the seismic isolation layer undergoes horizontal displacement, the components of the seismic isolation layer undergo horizontal shear displacement, and the tensile device undergoes horizontal displacement through the first friction pair 2 between the upper connecting plate 1 and the upper tensile plate 3, and the second friction pair 10 between the lower connecting plate 11 and the lower tensile plate 9, thereby ensuring that the components of the seismic isolation layer are not restricted in their horizontal movement; after a large earthquake occurs or the upper building has a tendency to collapse and an upper overturning moment is generated, the tensile device provides axial tension at this time to prevent the tension from acting on other components of the seismic isolation layer, thereby avoiding the force on other components; when the upper building generates an overturning moment, the rubber part in the tensile member 5 will first play a buffering role, generating an appropriate vertical displacement that can be lifted away; as the tension increases, after exceeding the deformation of the rubber part, the internal tensile member 5 begins to play its tensile role, and at this time plays a tensile role.

[0033] In the above embodiment, the first friction pair 2 and the second friction pair 10 are preferably formed of stainless steel plates and SF-1, but other materials may also be used. In this arrangement, when horizontal displacement occurs, the upper tensile plate 3 slides relative to the upper connecting plate 1, and the lower tensile plate 9 slides relative to the lower connecting plate 11, thereby achieving horizontal sliding without restricting the displacement of the seismic isolation structure of the isolation layer.

[0034] In some embodiments, the rubber member includes an elastic core rubber 6 and a leather rubber 7. The tensile member 5 is coated on the inside of the elastic core rubber 6, and the leather rubber 7 is coated on the outside of the elastic core rubber 6. The hardness of the leather rubber 7 is greater than the hardness of the elastic core rubber 6. In other words, the tensile member 5, the elastic core rubber 6, and the leather rubber 7 are combined into a combination. The tensile member 5 of the chain link has a certain gap between the rings. The elastic core rubber 6 fills the gaps between the rings of the chain link, and also fills the gaps between the tensile member 5 and the upper connecting member 4, and the gaps between the tensile member 5 and the lower connecting member 8. The tensile member 5 is wrapped with a high-hardness leather rubber 7. Finally, the rubber and chain link are vulcanized into shape using a mold. The rubber part plays the role of buffering and energy dissipation. When tension is generated, it will first play a buffering role. After buffering, the tensile member 5 plays a tensile role. Due to the high-hardness leather glue 7 vulcanized on the outside of the tensile member 5, the tensile device has a certain rigidity, so that it can move when the isolation layer moves. The rubber wrapping of the tensile member 5 makes it have a certain flexibility while having the rigidity of metal, and can be suitable for rotation. Therefore, during use, it can be used in conjunction with the isolation rubber bearing, and can also be used in conjunction with the friction pendulum isolation bearing, and its application range is wider.

[0035] In some embodiments, a first chute is provided on the upper connecting plate 1, the upper tensile plate 3 is provided in the first chute, and a first friction pair 2 is provided between the upper tensile plate 3 and the inner wall of the first chute; a second chute is provided on the lower connecting plate 11, the lower tensile plate 9 is provided in the second chute, and a second friction pair 10 is provided between the lower tensile plate 9 and the inner wall of the second chute. The upper connecting plate 1 and the lower connecting plate 11 are respectively connected to the building structure by anchor bolts or other means. The upper connecting plate 1 and the lower connecting plate 11 can be made into a plate-like structure or directly into a strip-like structure, wherein the first chute and the second chute are both slide rail structures, and the opening portion of the first chute on the upper connecting plate 1 is removed, and similarly, the opening portion of the second chute on the lower connecting plate 11 is removed to form a support step, which is used to provide support for the upper tensile plate 3 and the lower tensile plate 9.

[0036] According to some embodiments of the present invention, the first chute and the second chute are arranged in a crisscross pattern, that is, the first chute is arranged in a transverse pattern, and the second chute is arranged in a longitudinal pattern.

[0037] According to some embodiments provided by the present invention, the upper connector 4 and the lower connector 8 are both U-shaped members, the open ends of the two U-shaped members are respectively connected to the upper tensile plate 3 and the lower tensile plate 9, and the closed ends of the two U-shaped members are respectively connected to the tensile member 5. Specifically, the two open ends of the U-shaped member of the upper connector 4 are connected to the upper tensile plate 3 by nuts or other means such as welding, and the two open ends of the U-shaped member of the lower connector 8 are connected to the lower tensile plate 9 by nuts or other means such as welding, thereby forming an annular connection portion at one end of the upper connector 4 and the lower connector 8 facing the tensile member 5, and the annular connection portion is used to connect to the tensile member 5, that is, the annular connection portion is connected to the chain link.

[0038] See also Figure 3 According to some embodiments of the present invention, a plurality of tensile members 5 are provided between the upper connecting plate 1 and the lower connecting plate 11. Specifically, in this embodiment, two tensile members 5 are provided between the upper connecting plate 1 and the lower connecting plate 11. In other embodiments, the number of tensile members 5 can be set as needed.
