Description

Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to a connecting device for dampers. Background Art

[0002] High-rise building structures are significantly affected by earthquakes and wind shocks, and reducing the impact of earthquakes and wind shocks on high-rise building structures has become an important aspect of structural design. For this reason, technicians often use velocity dampers as shock-absorbing devices. Velocity dampers are generally made of viscous materials, including viscous dampers and viscoelastic dampers.

[0003] Among them, the viscous damper is mainly composed of a cylinder, a piston, a damping hole, a viscous material and a guide rod. The viscous material flows through the damping hole to balance the pressure difference generated by the relative movement of the piston and the cylinder. The damping generated absorbs most of the seismic energy and effectively reduces the vibration of the structure, so that it can be repaired in a large earthquake, repaired in a medium earthquake, and not damaged in a small earthquake.

[0004] Common fixing methods for viscous dampers include concrete pier wall connection, support connection and steel pier connection. At present, the above-mentioned fixing connection methods all use damper connectors and embedded parts for welding to form fixed supports. Due to the nature of concrete itself, the kinetic energy generated during an earthquake can easily cause cracks in the fixed supports, resulting in loose support fixation. Moreover, the connection between the damper connector and the embedded parts may suffer brittle failure or even breakage, thereby affecting the shock absorption effect of the damper.

[0039] like Figure 1-Figure 9 As shown, this embodiment provides a connection device for a damper, the damper 100 extends along the first direction and is arranged between the upper and lower building structures 200, and the connection device for the damper includes a first pad 1, a friction plate 2, a first connection member 3 and a second connection member 4. Among them, there are multiple first pads 1, and the multiple first pads 1 are arranged parallel to each other and spaced on the embedded parts 201 in the building structure 200 along the second direction, and the second direction is arranged at an angle to the first direction, and a friction plate 2 is sandwiched between each two adjacent first pads 1, one end of the first connection member 3 is connected to the embedded part 201, and the other end is connected to the first pad 1 and the friction plate 2, and the second connection member 4 is connected to one of the first pads 1, and the two ends of the damper 100 are respectively connected to the upper and lower building structures 200 through the second connection member 4.

[0040] In this embodiment, the damper 100 extends along the first direction and is arranged between the upper and lower building structures 200 to reduce the impact of earthquakes on the upper and lower building structures 200. The connecting device for the damper includes a first pad 1, a friction plate 2, a first connecting member 3 and a second connecting member 4. Among them, there are multiple first pads 1, and the multiple first pads 1 are parallel to each other and arranged at intervals on the embedded part 201 in the building structure 200 along the second direction, which can not only ensure the connection strength between the first pad 1 and the embedded part 201, but also facilitate the sandwiching of a friction plate 2 between each adjacent two first pads 1, so that both sides of the friction plate 2 are in contact with the first pad 1, improve the friction between the components, and absorb part of the earthquake energy through the relative displacement between the first pad 1 and the friction plate 2. One end of the first connecting member 3 is connected to the embedded part 201, and the other end is connected to the first pad 1 and the friction plate 2, so that the first pad 1, the friction plate 2 and the embedded part 201 form an integral structure, ensuring the connection strength of the damper 100 connected to the building structure 200 through the integral structure. The second connecting member 4 is connected to one of the first pads 1, and the two ends of the damper 100 are respectively connected to the upper and lower building structures 200 through the second connecting member 4. When the upper and lower buildings are displaced in the first direction under the action of an earthquake, the damper 100 and the second connecting member 4 can drive the first pad 1 to displace relative to the friction plate 2 to a certain extent, thereby absorbing the earthquake energy, reducing the damage to the building structure 200 caused by the earthquake, and avoiding brittle failure between the damper 100 and the embedded part 201. Through the above arrangement, the connection device for the damper of this embodiment can improve the earthquake resistance of the building structure 200 and reduce the damage between the damper 100 and the embedded part 201.

[0041] It should be noted that if Figure 1 As shown, in this embodiment, the first direction is the horizontal direction and the second direction is the vertical direction, so that the connection device can provide stable support and damping effect during an earthquake. In other embodiments, the first direction and the second direction can be adjusted according to the specific form of the building structure 200, and no further limitation is made here. In addition, the damper 100 belongs to the existing equipment in the field, and the technicians in the field are clear about its working principle, which will not be repeated here.

[0042] Specifically, Figure 1-Figure 5 As shown, the first pad 1 is provided with a plurality of threaded holes 11, and the plurality of threaded holes 11 are arranged at intervals along the circumference of the first pad 1. A plurality of first connecting members 3 are provided, and the plurality of first connecting members 3 are respectively connected to the plurality of threaded holes 11. The plurality of first connecting members 3 are evenly distributed around the circumference of the first pad 1, so that the connection between the damper 100 and the building structure 200 can be ensured to be more stable, and multi-point fixation can be formed, thereby improving the connection strength between the damper 100 and the building structure 200.

[0043] Specifically, Figure 1-Figure 4 As shown, the embedded part 201 includes a connecting plate 2011 and a plurality of anchors 2012 arranged side by side and at intervals, which can ensure that the connection between the embedded part 201 and the building structure 200 is more stable. Under the action of external forces such as earthquakes, the anchors 2012 can evenly share the load, reduce stress concentration, and improve the connection strength between the components. One end of the anchor 2012 is connected to the connecting plate 2011, and the other end can be placed in the building structure 200, so that the embedded part 201 can be firmly embedded in the building structure 200. When an earthquake occurs, a stable overall structure can be formed between the embedded part 201 and the building structure 200 to jointly resist the action of the earthquake force and improve the earthquake resistance of the building structure 200.

[0044] More specifically, if Figure 1-Figure 4 As shown, an anchor head is provided at one end of the anchor 2012 placed in the building structure 200 to ensure a more stable connection between the anchor 2012 and the building structure 200. The tight connection between the anchor head and the building structure 200 can effectively prevent the anchor 2012 from loosening or falling off when subjected to external force.

[0045] More specifically, the connection plate 2011 and the anchor 2012 are connected by plug welding to improve the connection strength between the connection piece and the anchor 2012.

[0046] Specifically, the friction plate 2 is provided with anti-skid patterns to further increase the friction between the first pad 1 and the friction plate 2. The anti-skid patterns can also improve the damping effect between the damper 100 and the building structure 200. Under the action of external forces such as earthquakes, the damper 100 can consume energy through the relative movement between the friction plate 2 and the first pad 1, reducing the impact on the building structure 200. The anti-skid patterns can enhance the damping effect and improve the earthquake resistance of the building structure 200.

[0047] Specifically, Figure 1 and Figure 2 As shown, the connection device for the damper also includes a second pad 5, which is connected to the first pad 1 and the friction plate 2 through the first connection member 3, so that the first pad 1, the friction plate 2, the second pad 5 and the embedded part 201 form an integral structure, and the other end of the first connection member 3 can abut against the second pad 5, and the second pad 5 is pressed against the first pad 1, and a certain damping effect can be generated through the relative movement between the first pad 1 and the second pad 5 and the friction plate 2. When an earthquake occurs, the damper 100 can consume the earthquake energy through these relative movements, further reducing the impact on the building structure 200.

[0048] Specifically, Figure 1-Figure 9As shown, the second connecting member 4 includes an ear plate 41 and a flat plate 42 which are connected to each other. The flat plate 42 can be connected to the first pad 1 by bolts. The ear plate 41 is used to connect the damper 100, making the installation and disassembly process of each component easier, thereby reducing vibration and displacement and ensuring the effective operation of the damper 100.

[0049] More specifically, two ear plates 41 are provided, and the two ear plates 41 are spaced apart on the flat plate 42 and are provided with coaxially arranged through holes, through which bolts or pins are passed and connected to the damper 100, so that the damper 100 can be subjected to force more evenly, and the connection between the damper 100 and the first pad 1 is more stable and effective.

[0050] Specifically, the first connecting member 3 is a bolt, so as to improve the connection strength of each component and facilitate installation and disassembly.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
