Description

[0002] Building structures are prone to node damage or even overall collapse under the action of earthquakes, which in turn causes serious secondary disasters. For example, suspended ceiling systems are widely used in various public buildings and industrial buildings.

However, direct and simple reinforcement will reduce the structural ductility and cause large-scale sudden damage under the action of larger or multiple earthquakes. Therefore, there is an urgent need for a connecting piece with reasonable structure, significant energy consumption effect and protection of structural ductility to improve the safety and reliability of suspended ceiling systems and other structures under the action of earthquakes.

[0025] The present application aims to provide a friction damping and energy dissipation connecting piece, which can enhance the stability of the connection in a small intensity earthquake, and enhance the ductility of the structure to prevent large-scale sudden damage in a large intensity earthquake and multiple earthquakes.

[0026] To achieve the above-mentioned purpose, please refer to Figure 1 , Figure 1 The structure diagram of the friction damping and energy dissipation connecting piece provided by an embodiment of the present application is shown in the figure. Figure 1 The present application provides a friction damping and energy dissipation connecting piece, which comprises a first connecting unit 01, a second connecting unit 02, a first energy dissipation subsystem and a second energy dissipation subsystem; one end of the first energy dissipation subsystem is connected with the first connecting unit 01, and the other end is connected with the second connecting unit 02; one end of the second energy dissipation subsystem is connected with the first connecting unit 01, and the other end is connected with the second connecting unit 02; the first energy dissipation subsystem and the second energy dissipation subsystem are both used to consume the kinetic energy from the first connecting unit 01 and / or the second connecting unit 02 when the first connecting unit 01 and / or the second connecting unit 02 moves; the breaking strength of the first energy dissipation subsystem is greater than or equal to a first preset threshold, the breaking strength of the second energy dissipation subsystem is greater than or equal to a second preset threshold, and the first preset threshold is smaller than the second preset threshold; the system stiffness of the first energy dissipation subsystem is greater than the system stiffness of the second energy dissipation subsystem.

[0027] Since the system stiffness of the first energy dissipation subsystem is greater than the system stiffness of the second energy dissipation subsystem, the overall deformation of the present application is small due to the connection constraint of the first energy dissipation subsystem in a small earthquake, thereby achieving the reinforcing and stabilizing effect in a small earthquake. However, under the fatigue effect of several small earthquakes or the fierce action of a large earthquake, since the breaking strength of the first energy dissipation subsystem is greater than or equal to the first preset threshold, the breaking strength of the second energy dissipation subsystem is greater than or equal to the second preset threshold, and the first preset threshold is smaller than the second preset threshold. The scenario corresponding to the first preset threshold is a preset small earthquake intensity, at this time, the first energy dissipation subsystem is damaged first, and the second energy dissipation subsystem starts to dissipate energy and continues to consume the kinetic energy from the first connecting unit 01 and / or the second connecting unit 02. At this time, the second energy dissipation subsystem can improve the ductility of the structure to avoid large-scale sudden damage. In summary, the present application can enhance the stability of the connection in a small intensity earthquake, and enhance the ductility of the structure to prevent large-scale sudden damage in a large intensity earthquake and multiple earthquakes.

[0028] Please continue to refer to Figure 1, specifically, the first energy dissipation subsystem includes a connecting plate 10, a first fastener and a second fastener; one end of the connecting plate 10 is connected with the first connecting unit 01 by the first fastener, and the other end is connected with the second connecting unit 02 by the second fastener. In an exemplary embodiment, the first connecting unit 01 is provided with a first sliding groove 010 penetrating through itself, and the second connecting unit 02 is provided with a second sliding groove 020 penetrating through itself; one end of the connecting plate 10 is provided with a first adaptive groove penetrating through itself and matching with the first sliding groove 010, and the other end is provided with a second adaptive groove penetrating through itself and matching with the second sliding groove 020; the first fastener penetrates through the first sliding groove 010 and the first adaptive groove, so that the connecting plate 10 and the first connecting unit 01 abut against each other and can move relatively; the second fastener penetrates through the second sliding groove 020 and the second adaptive groove, so that the connecting plate 10 and the second connecting unit 02 abut against each other and can move relatively. In this way, the first energy dissipation subsystem realizes energy dissipation by utilizing the friction between the connecting plate 10, the first connecting unit 01 and the second connecting unit 02.

[0029] In order to make the first energy dissipation subsystem break down preferentially to the second energy dissipation subsystem, the connecting plate 10 should be provided with a stress concentration groove 100. The stress concentration groove 100 can be arranged on the part of the connecting plate 10 between the first connecting unit 01 and the second connecting unit 02, which can be a groove penetrating through both sides of the connecting plate 10 by thinning the part, or a through groove penetrating through both sides of the connecting plate 10 by punching a hole in the area, so as to make the connecting plate 10 break down at the stress concentration groove 100 preferentially by utilizing the stress concentration principle. It should be noted that the breaking strength corresponding to the breaking of the stress concentration groove 100 is the breaking strength of the first energy dissipation subsystem, that is, once the first energy dissipation subsystem loses the constraint ability due to breaking, the strength is the breaking strength of the first energy dissipation subsystem.

[0030] In addition to utilizing the stress concentration principle to make the first energy dissipation subsystem break down preferentially, the fatigue loosening of the screw thread can also be utilized. Based on this, the present application further provides the following technical solutions: the first fastener and / or the second fastener includes a nut 12 and a bolt 11, and the nut 12 and the bolt 11 are threadedly connected; the first fastener and / or the second fastener further includes a sleeve (not shown in the figure), which is sleeved on the outer rod of the bolt 11 and can slide axially along the bolt 11, so that the nut 12 is arranged close to the outer end of the bolt 11. When subjected to multiple or large earthquakes, the nut 12 will gradually loosen, and since it is arranged close to the outer end of the bolt 11, i.e. the free end, the nut 12 will fall off, resulting in the disassembly and breaking of the entire first energy dissipation subsystem.

[0031] Please continue to refer to Figure 1 , the second energy dissipation subsystem comprises a first fixed rod 22, a second fixed rod 23 and a damping rod 21; the first fixed rod 22 is connected with the first connecting unit 01, and the second fixed rod 23 is connected with the second connecting unit 02; one end of the damping rod 21 is connected with the first fixed rod 22, and the other end is connected with the second fixed rod 23; the damping rod 21 can provide a damping force along the axial direction of the damping rod 21 to consume the kinetic energy from the first connecting unit 01 and / or the second connecting unit 02 when the first connecting unit 01 and / or the second connecting unit 02 moves. In this way, when the seismic action occurs, part of the kinetic energy is converted into the axial release along the damping rod 21, and at this time the damping force along the axial direction of the damping rod 21 is consumed by using the damping force along the axial direction of the damping rod 21.

[0032] Please refer to Figure 2 , the damping force of the damping rod 21 can be achieved by the following setting: the damping rod 21 comprises an outer tube 210 and an inner tube 211, the outer tube 210 is sleeved outside the inner tube 211, and the inner circumferential surface of the outer tube 210 and / or the outer circumferential surface of the inner tube 211 is provided with damping material (see 2101 and 2111 in Figure 2 It should be noted here that the damping material in this setting can make the damping rod 21 provide a damping force along the axial direction of the damping rod 21, and if part of the kinetic energy is converted into a force that twists the damping rod 21 when the seismic action occurs, the damping material can still provide a damping force in the twisting direction by the mutual twisting of the inner tube 211 and the outer tube 210, which will not be described here.

[0033] Please refer to Figure 1 Further, the damping force of the damping rod 21 under the bending rotation condition should also be considered, and based on this, the following setting is made: one end of the damping rod 21 is provided with a first sleeve hole 2100, and the other end is provided with a second sleeve hole 2110; the first fixed rod 22 penetrates through the first sleeve hole 2100, and the second fixed rod 23 penetrates through the second sleeve hole 2110; a second energy dissipation piece 24 is sleeved on the first fixed rod 22 and / or the second fixed rod 23, so that when the damping rod 21 moves on the first fixed rod 22 and / or the second fixed rod 23, the kinetic energy of the damping rod 21 is consumed. The second energy dissipation piece 24 can be an elastic piece or other energy dissipation piece that can provide a damping force. It should be understood that nuts 12 can also be further sleeved on the first fixed rod 22 and the second fixed rod 23 to limit the spatial range of the damping rod 21, which will not be described here.

[0034] In conclusion, the present application considers the damping energy consumption of the damping rod 21 in various motion states. When the damping rod 21 is extended and retracted along the axial direction of the damping rod 21 (the first connecting unit 01 and the second connecting unit 02 repeatedly approach and move away from each other), the axial relative motion of the inner tube 211 and the outer tube 210 can be used to provide damping force. When the damping rod 21 is twisted due to the oscillation of both ends of the damping rod 21 around the axial line of the damping rod 21 (the first connecting unit 01 and the second connecting unit 02 are twisted relative to each other), the inner tube 211 and the outer tube 210 use relative twisting to provide damping force. When the damping rod 21 rotates in the plane determined by the axial line of the damping rod 21 and the axial line of the first fixed rod 22 or the axial line of the second fixed rod 23 (the first connecting unit 01 and the second connecting unit 02 move up and down relative to each other), the second energy consumption part 24 can be set as an elastic part or a flexible part that can abut against the side of the damping rod 21 to provide damping force. When the first fixed rod 22 rotates around the axial line of the first fixed rod 22 or the second fixed rod 23 (the first connecting unit 01 and the second connecting unit 02 move horizontally relative to each other), the second energy consumption part 24 can be set as a torsional spring or a friction layer that rubs against the inner wall of the first sleeve hole 2100 or the second sleeve hole 2110 to provide damping force.

[0035] Similarly, the first energy consumption subsystem can also be optimized in a similar manner. Based on this, the present application is provided as follows: the first fastener and / or the second fastener includes a nut 12 and a bolt 11, and the nut 12 and the bolt 11 are threadedly connected; a first energy consumption part 13 is sleeved on the shank of the bolt 11, so that when the first fastener and / or the second fastener and at least one of the connecting plate 10, the first connecting unit 01 and the second connecting unit 02 move relative to each other, the kinetic energy of the relative motion is consumed. The first energy consumption part 13 can also be an elastic part abutting against the surface of the connecting plate 10 to handle the rotation of the connecting plate 10 in the plane of the axial line of the bolt 11, or the first energy consumption part 13 can also be a torsional spring or a friction part to provide damping force when the connecting plate 10 rotates around the axial line of the bolt 11.

[0036] Please refer to Figure 3 , Figure 3 The friction damping cooperative energy consumption connecting piece provided by an embodiment of the present application is applied to a structural schematic view of structural connection. As shown in Figure 3As shown, the application also provides a connection structure, comprising a first component 1, a second component 2 and the friction damping cooperative energy dissipation connecting piece 3 as described in any of the above, the first connecting unit 01 is connected with the first component 1, and the second connecting unit 02 is connected with the second component 2. Since the connection structure comprises the friction damping cooperative energy dissipation connecting piece 3, the connection structure can enhance the connection stability under small intensity earthquake, and enhance the structure ductility to prevent large-scale sudden damage under large intensity earthquake and multiple earthquakes. In an exemplary embodiment, the first component 1 and the second component 2 are suspended ceilings, which are connected with the top of the floor by a hanger 4.
