Description

TECHNICAL FIELD

[0001] The present application relates to the field of building structure damping, and in particular to a gapless viscous damper. BACKGROUND

[0002] In building structures, in order to improve the safety and stability of the structure under dynamic load such as earthquake and wind vibration, it is often necessary to install a damper to dissipate energy and reduce the vibration response of the structure. The existing viscous damper often has a connection gap when connected to the corresponding structure, which can cause the damper to fail to function in time in the small deformation stage, reducing the efficiency of the damper in controlling the vibration of the structure. When the vibration amplitude of the building structure is small, due to the existence of the gap, the damper cannot immediately participate in energy dissipation work, so that the building structure cannot be effectively damped in the initial vibration stage, which may cause a certain degree of damage to the building structure. CONTENT

[0003] Therefore, the purpose of the present application is to provide a gapless viscous damper to solve the problem that the existing damper cannot function in time in the small deformation stage.

[0004] In order to achieve the above purpose, the utility model provides a gapless viscous damper, wherein the gapless viscous damper comprises:

[0005] A damper body is formed with a fixed part, and the fixed part is formed with a spherical surface structure.

[0006] A fixing assembly is formed with a groove corresponding to the fixed part, and the fixed part and the groove are correspondingly assembled to make the damper body and the fixing assembly have no gap.

[0007] Preferably, the fixed part comprises a spherical part, a transition part and a cylindrical part connected in sequence along a first direction.

[0008] Preferably, the spherical part is formed as a hemispherical structure.

[0009] Preferably, the transition part is formed as a columnar structure; along the first direction, the diameter of the transition part gradually decreases, and the diameter of the first end of the transition part connected with the spherical part is greater than the second end of the transition part connected with the cylindrical part.

[0010] Preferably, the fixing assembly comprises a first fixing part corresponding to the fixed part; the first fixing part comprises a base and a clamping part arranged in sequence along the first direction.

[0011] Preferably, along the first direction, the end face of the base close to the fixed part is formed with a fixed groove corresponding to the spherical part; the spherical part is fitted with the fixed groove.

[0012] Preferably, the clamping piece comprises a first clamping piece and a second clamping piece detachably connected with the first clamping piece; the first clamping piece and the second clamping piece are both formed with an arc-shaped recess, and when the first clamping piece and the second clamping piece are correspondingly connected, the two arc-shaped recesses are combined into a through hole corresponding to the transition part; the transition part is fitted with the through hole.

[0013] Preferably, the first clamping piece and the second clamping piece are respectively detachably connected with the base.

[0014] Preferably, the fixing assembly further comprises a second fixing piece, and the base is correspondingly detachably connected with the second fixing piece.

[0016] According to the gapless viscous damper, the gapless connection of the damper body and the fixing assembly can be realized by setting the groove corresponding to the fixing part of the damper body, even if the displacement amount is very small in the initial stage of the building structure vibration, the damper body can immediately respond and play a role, so that the relative movement between the piston rod and the cylinder can be timely transmitted, and the damper can continuously play a role in the whole vibration process.

In the following, the specific structure and connection relationship of each part of the gapless viscous damper according to the utility model will be described in detail.

[0032] In the embodiment, as shown in the figure, Figure 1 The damper body 1 includes a cylinder, a piston 12 and a piston rod 11, the piston 12 is formed with a through hole, the piston 12 is sleeved on the outer side of the piston rod 11 through the through hole and is welded and fixed with the piston rod 11 (that is, there is no relative movement between the two), the piston 12 and the piston rod 11 are arranged in the inside of the cylinder; In addition, a plurality of damping holes are formed in the body of the piston 12. Further, the two ends of the extension direction of the piston rod 11 extend to the outside of the cylinder to form a fixing part of the damper body 1 respectively; Further, the inside of the cylinder is formed into a sealed cavity, and the inside is filled with energy consumption medium.

[0033] In the embodiment, as shown in the figure, Figure 1 The fixing part of the damper body 1 is formed with a spherical surface structure, so as to facilitate improving the tightness of the connection with the fixing assembly. Specifically, the fixing part includes a spherical part 111, a transition part 112 and a cylindrical part 113 connected in sequence along a first direction (the first direction is the same as the extension direction of the above-mentioned damper body 1). The spherical part 111 is formed into a hemispherical structure; the transition part 112 is formed into a columnar structure, along the first direction, the diameter of the transition part 112 gradually decreases, and the diameter of the first end of the transition part 112 connected with the spherical part 111 is greater than the second end of the transition part 112 connected with the cylindrical part 113; That is, the fixing part is formed into a structure similar to a bulb.

Based on the variable diameter structure of the transition portion 112, the first clamping piece 2121 and the second clamping piece 2122 are clamped from both ends (radially) of the transition portion 112 respectively, so that the transition portion 112 is fitted with the through hole (i.e. the two arc-shaped recesses), and then the first clamping piece 2121 and the second clamping piece 2122 are tightly connected through threaded connection (the threaded hole 3 is shown as follows).
