Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0022] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0023] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0024] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0025] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another.

[0030] This utility model provides a viscous damper, such as Figure 1 As shown, the viscous damper in this embodiment includes a damper body 1 and a connecting component 2. The damper body 1 is stably mounted at a predetermined position on the building structure via the connecting component 2 to dissipate dynamic loads. The specific structure and connection relationships of the aforementioned parts of the viscous damper according to this invention will be described in detail below.

[0031] In this embodiment, as Figure 1As shown, the damper body 1 includes a cylinder 11, a piston, and a piston rod 12. The piston has a through hole and is fitted onto the outer side of the piston rod 12 through the through hole, and is welded and fixed to the piston rod 12 (i.e., there is no relative movement between them). Both the piston and the piston rod 12 are disposed inside the cylinder 11. In addition, multiple damping holes are formed in the piston body. Furthermore, both ends of the piston rod 12 extend to the outside of the cylinder 11 in the extending direction to form a first connecting end 121 and a second connecting end 122, respectively. Furthermore, the interior of the cylinder 11 is formed as a sealed cavity, and its interior is filled with an energy-dissipating medium. It should be noted that the damper is an existing structure, so its specific structure will not be described in detail. When the building structure vibrates under the action of earthquake or wind load, the piston rod 12 of the damper will reciprocate relative to the cylinder 11, thereby driving the piston to reciprocate within the cylinder 11. In this way, the energy dissipating medium can flow through the damping hole on the piston, generating viscous damping force, and realizing the initial dissipation of vibration energy.

[0032] In this embodiment, as Figure 1 As shown, two connecting components 2 are provided, which are respectively connected to the first connecting end 121 and the second connecting end 122 of the damper body 1. Specifically, each connecting component 2 includes a first connecting member 21 and a second connecting member 22 threadedly connected to the first connecting member 21. The first connecting member 21 is correspondingly connected to the damper body 1, and the second connecting member 22 is disposed at a predetermined position in the corresponding site of the building.

[0033] like Figure 1 As shown, the first connector 21 has a large-diameter end and a small-diameter end connected sequentially along a first direction (the first direction is the same as the extension direction of the piston rod 12). The small-diameter end is connected to the damper body 1, and the large-diameter end is connected to the second connector 22. The second connector 22 is formed into a wedge-shaped structure, specifically including three connecting plates 221 and multiple trapezoidal reinforcing plates 222. The three connecting plates 221 respectively form the top, side, and bottom ends of the second connector 22. The reinforcing plates 222 can improve the stability and structural strength of the second connector 22 and the entire viscous damper.

[0034] It should be noted that there are no specific restrictions on the specifications of the first connector 21 and the second connector 22. They should be determined comprehensively based on the actual situation, such as the specifications of the damper body 1, as long as the aforementioned technical effects can be achieved. In addition, in the second connector 22, the connecting plate 221 and the reinforcing plate 222 can be connected by welding to ensure the structural strength of the second connector 22. Furthermore, the second connector 22 can be prefabricated to improve the efficiency and convenience of on-site installation of this damper.

[0035] More specifically, a plurality of first threaded holes 211 are formed at the large-diameter end of the first connector 21. The plurality of first threaded holes 211 are spaced apart (encircling the small-diameter end) and penetrate the large-diameter end along the first direction. The connecting plate 221 at the side end of the second connector 22 (i.e., the end face of the second connector 22 near the first connector 21 along the first direction) is formed with a plurality of second threaded holes 223 corresponding one-to-one with the first threaded holes 211. Corresponding studs are provided in the first threaded holes 211 and the second threaded holes 223. The studs are also connected to corresponding nuts. The nuts abut against the end face of the large-diameter end near the small-diameter end, so that the end face of the large-diameter end away from the small-diameter end fits against the second connector 22. This reduces the gap between the components, so that even if the vibration displacement of the building structure is very small, this damper can respond immediately.

[0036] It should be noted that the specifications, quantity, and specific location of the first threaded hole 211 (second threaded hole 223) are not fixed, as long as the above-mentioned technical effects can be achieved.

[0037] According to the viscous damper of this utility model, the damper body 1 is connected to the connecting component 2 through the first connecting end 121 and the second connecting end 122. The damper can be set at the corresponding position of the building structure through the connecting component 2. Furthermore, the connecting component 2 in this application includes a first connecting member 21 and a second connecting member 22 that is threadedly connected to the first connecting member 21. That is, when the damper in this application is connected to the on-site building structure, a threaded connection method is adopted. Compared with the existing welding connection method, there is no need to equip professional welders and supervisors, and the installation method is less difficult.

[0038] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
