[0033] like Figures 1 to 3 As shown, this embodiment proposes a shock-absorbing connection device, including a male connector 100 and a female connector 200. The male connector 100 includes a male sleeve 110 and a bolt 120. The male sleeve 110 has a receiving cavity 111 formed inside. The bolt 120 includes a head 121 and a connecting rod 122. The head 121 is located inside the receiving cavity 111, and one end of the connecting rod 122 extends out of the receiving cavity 111. The female connector 200 includes a female sleeve 210 and a nut 220. The female sleeve 210 has an mounting cavity 211 formed inside. The female connector 220 is located within the mounting cavity 211. When the male connector 100 is assembled with the female connector 200, the connecting rod 122 of the bolt 120 is inserted into the mounting cavity 211 of the female connector sleeve 210 and threadedly connected to the nut 220. A damping element 300 is sleeved on the connecting rod 122. The damping element 300 is located within the male connector sleeve 110 or the female connector sleeve 210 and is used to apply an axial damping force to one of the bolt head 121 or the nut 220, causing the bolt 120 and the nut 220 to move away from each other.
[0034] In this technical solution, by setting a damping element 300 inside the male sleeve 110 or the female sleeve 210, when the male sleeve 110 and the female sleeve 210 (building body) vibrate, the damping element 300 applies axial damping force to the bolt 120 and the nut 220, so that the vibration amplitude gradually decreases and the building body is prevented from being damaged under continuous large-amplitude vibration.
[0035] In some embodiments, such as Figure 1 As shown, the shock-absorbing connector includes a male assembly 100 and a female assembly 200. The male assembly 100 includes a male sleeve 110, a bolt 120, and a first connector 130. A receiving cavity 111 is formed inside the male sleeve 110, and the receiving cavity 111 has an opening. The first connector 130 is detachably and fixedly connected to the opening of the receiving cavity 111. The male sleeve 110 and the first connector 130 restrict the head 121 of the bolt 120 within the receiving cavity 111. The connecting rod 122 of bolt 120 passes through the first connecting member 130 and can be inserted into the female connector assembly 200 for threaded connection with nut 220. The female connector assembly 200 includes a female connector sleeve 210, nut 220, and a second connecting member 230. The female connector sleeve 210 has a mounting cavity 211 with an opening. The opening of the mounting cavity 211 is detachably connected to the second connecting member 230, and the second connecting member 230 and the female connector sleeve 210 cooperate. The nut 220 is confined within the mounting cavity 211 of the female sleeve 210, and both the second connector 230 and the first connector 130 are sleeved on the connecting rod 122 of the bolt 120. That is, the connecting rod 122 of the bolt 120 can pass through the first connector 130 and the second connector 230 and be threadedly connected to the nut 220. The damping element 300 is sleeved on the connecting rod 122 of the bolt 120 and located inside the male sleeve 110. The damping element 300 abuts against the bottom surface of the head 121 of the bolt 120 and the top surface of the first connector 130 at both ends along the damping force it applies (as shown in the figure). That is, when the bolt 120 vibrates, the damping element 300 can apply a damping force to the bolt 120 to reduce or resolve the vibration impact damage to the bolt 120, improve the connection toughness of the joint, and avoid continuous large-amplitude rigid collisions or continuous rigid forces between building structures that could damage the building structure. Both the receiving cavity 111 of the male sleeve 110 and the mounting cavity 211 of the female sleeve 210 are provided with an elastic element 400. The two elastic elements 400 apply relative forces to the bolt 120 and the nut 220 respectively, which makes the installation connection between the bolt 120 and the nut 220 more convenient (facilitating docking and tightening during installation), and also helps to reduce the vibration amplitude of the bolt 120 and the nut 220.
[0036] Specifically, such as Figure 2As shown, in this embodiment, the nut 220 is generally wedge-shaped with its outer surface being an inclined surface. The inner surface of the second connector 230 is sleeved on the outer surface of the nut 220, and a conical cavity that mates with the nut 220 is formed inside the second connector 230. When the nut 220 is tightened on the bolt 120, the wedge-shaped inclined surface of the nut 220 is fitted into the conical cavity of the second connector 230. The friction between the outer surface of the nut 220 and the inner surface of the second connector 230 prevents rotation between the nut 220 and the second connector 230.
[0037] Specifically, such as Figure 4 As shown, no elastic element 400 is provided on the top surface of the bolt head 121 inside the male sleeve 110, and a gap is formed between the bolt head 121 and the top inner wall of the receiving cavity 111 so that the bolt 120 is prevented from colliding with the receiving cavity 111 when vibrating.
[0038] In some embodiments, such as Figure 3As shown, the shock-absorbing connector includes a male assembly 100 and a female assembly 200. The male assembly 100 includes a male sleeve 110, a bolt 120, and a first connector 130. A receiving cavity 111 is formed within the male sleeve 110, and the receiving cavity 111 has an opening. The first connector 130 is detachably and fixedly connected to the opening of the receiving cavity 111. The male sleeve 110 and the first connector 130 confine the head 121 of the bolt 120 within the receiving cavity 111. The connecting rod 122 of bolt 120 passes through the first connecting member 130 and can be inserted into the female connector assembly 200 for threaded connection with nut 220. The female connector assembly 200 includes a female connector sleeve 210, nut 220, and a second connecting member 230. The female connector sleeve 210 has a mounting cavity 211 with an opening. The opening of the mounting cavity 211 is detachably connected to the second connecting member 230. The second connecting member 230 and the female connector sleeve 210 cooperate to... Nut 220 is confined within the mounting cavity 211 of the female sleeve 210, and the second connector 230 and the first connector 130 are both sleeved on the connecting rod 122 of the bolt 120. That is, the connecting rod 122 of the bolt 120 can pass through the first connector 130 and the second connector 230 and be threadedly connected to the nut 220. The damping element 300 is sleeved on the connecting rod 122 of the bolt 120 and located within the female sleeve 210. The damping element 300 abuts against the top surface of the nut 220 and the bottom surface of the second connector 230 at both ends along the damping force it applies (as shown in the figure). That is, when the bolt 120 vibrates, the damping element 300 can apply a damping force to the bolt 120 through the nut 220 to reduce or resolve the vibration impact damage to the bolt 120, improve the connection toughness of the joint, and avoid continuous large-amplitude rigid collisions or continuous rigid forces between building structures that could damage the building structure.
[0039] Specifically, in the above embodiments, the elastic element 400 is configured as a compression spring, and the shock-absorbing damping element 300 can also be configured as a damping spring or compression spring, or a damping sleeve made of rubber or other elastic materials, as well as a composite damping assembly formed by a combination of other one or more materials and structures. The forms and structures of compression springs and damping springs in this embodiment are not intended to limit this embodiment. Any device that can provide damping force can be used as the shock-absorbing damping element 300 of this application.
[0040] like Figure 5As shown, in some embodiments, the damping components 300 are all located within the receiving cavity 111. Simultaneously, the receiving cavity 111 and the mounting cavity 211 are also provided with elastic elements. These elastic elements are configured as compression springs, applying a force to the bolt 120 and nut 220 to make them face each other, facilitating installation. The damping components 300 are configured as tension springs (or other devices with the same function as tension springs, such as elastic ropes). One end of the tension spring is fixedly connected to the top wall of the receiving cavity 111, and the other end is fixedly connected (or alternatively, a rotatable connection that is radially rotatable but axially fixed) to the head 121 of the bolt 120. This is in the normal assembly state of the male connector 100 and the female connector 200. In this configuration, the elastic elements located in the receiving cavity 111 and the mounting cavity 211 respectively apply a thrust to the bolt 120 and the nut 220, causing them to move towards each other. The damping element 300 is in a natural state (without or considered to exert no force on the bolt). When an external force causes the bolt 120 to move downward, the deformation of the compression spring gradually decreases, and the thrust it applies gradually decreases, while the deformation of the damping element 300 gradually increases, and the tension it applies gradually increases. When the thrust applied by the tension spring to the bolt 120 is less than the tension applied by the damping element 300 to the bolt 120, the damping element 300 applies a damping force to the bolt 120 to prevent it from moving, thereby reducing or mitigating the vibration impact damage to the bolt 120 and improving the connection toughness of the joint. In other embodiments, the damping component 300 may also be disposed in the mounting cavity 211 of the female sleeve 200, with one end fixedly connected to the inner wall of the mounting cavity 211 and the other end fixedly connected to (or may be configured as a rotatable connection that can rotate in the radial direction but is fixed in the axial direction) the nut, which is used to apply a tensile force in the axial direction to the nut. The specific implementation process is similar to that described above and will not be repeated here.
[0041] Furthermore, in the above embodiments, the damping coefficient of the elastic element 400 is less than the damping coefficient of the shock-absorbing damping element 300. That is, under the same deformation, the change in force of the elastic element 400 is less than the change in force of the shock-absorbing damping element 300, so that the shock-absorbing damping element 300 can quickly respond to the vibration displacement of the bolt or nut.
[0042] like Figure 6As shown, this embodiment also proposes a building structure, including a first prefabricated component 500 and a second prefabricated component 600. The first prefabricated component 500 and the second prefabricated component 600 are connected by a vibration-damping connection device as described in any of the above embodiments. The first prefabricated component 500 and the second prefabricated component 600 are provided with the male connector 100, and the other is provided with a female connector 200. The reasoning process for the beneficial effects of the building structure provided in this application and the aforementioned vibration-damping connection device is similar, and will not be repeated here.
[0043] In summary, the shock-absorbing connection device and building structure provided in this embodiment have the advantages of convenient installation and good shock absorption effect. They can reduce or mitigate the vibration amplitude of the building during an earthquake and prevent damage caused by violent collisions between buildings.
