Embodiment 1

[0031] Embodiment 1: as figure 1 and 3 As shown, a plate-type viscous damper 2 includes: an upper shear plate 6, a lower cavity 8 plates, a limit buckle assembly 9, and a flexible dustproof cover 7. The structure is simple, no pressure seal is required, and the working life is long. The shearing plate 6 is inserted into the lower cavity 8 with gaps; the upper shearing plate 6 is symmetrically opened with limiting holes on the plate surface, and the limiting buckle assembly 9 is fastened on the limiting hole, and the upper shearing plate 6 is inserted into the lower cavity. When the cavity is 8, the two ends of the limit buckle assembly 9 are matched with the inner wall surface of the lower cavity 8 with a small gap; During movement, the limit buckle assembly 9 ensures that the gap between the two fluctuates in a small range; the surroundings and the bottom surface of the lower cavity 8 are closed, and the top surface is open, without pressure sealing; the damping fluid filled...

Embodiment 2

[0033] Embodiment 2: as image 3 and 4 As shown, this embodiment is an improvement on Implementation 1; the wall of the upper shear plate 6 of the plate-type viscous damper 2 and the corresponding shear cavity of the lower cavity 8 can form a multi-cavity structure, and the multi-cavity parallel connection can be obtained from the structure and damping output optimization design. In other embodiments, an insert plate may also be added in the lower cavity 8, or ribs vertical to the plate surface may be added on the plate surface to form a multi-cavity structure.

Embodiment 3

[0034] Embodiment 3: on the basis of embodiment 1 or 2, as Figure 7 , 8 As shown, a mounting plate 15 is connected to the top of the upper shearing plate, and several waist-shaped holes 14 are provided on the mounting plate 15. When the upper shearing plate 6 is installed and fixed, it can be installed and fixed with the upper connecting plate 1 through the waist-shaped holes. , and the distance between the upper shear plate 6 and the inner wall of the lower cavity 8 can be adjusted through the waist hole 14 . Then change the damping coefficient to meet the shock absorption requirements of different building structures.

Abstract

The invention discloses a plate type viscous damper, a tuned mass damper and a damper coefficient adjusting method, and relates to the technical field of building quakeproof. The damper comprises a lower cavity for containing damping liquid and an upper shear plate arranged in the cavity, wherein the lower cavity is vertically arranged and is of a lower sealing cavity structure with the bottom and the side parts sealed, the shape of an upper shearing plate matches with that of the lower cavity, the upper shearing plate is vertically inserted into the lower cavity from the upper portion, a gap is formed between the upper shearing plate and the inner wall of the lower cavity, the wall face of the upper shearing plate and the wall face of the lower cavity can vertically move relative to each other to shear damping fluid, the upper shearing plate and the lower cavity move in the opposite direction in the building vibration process through inertia, so that vibration energy is reduced, the quakeproof effect is achieved. The plate type viscous damper, the tuned mass damper and the damper coefficient adjusting method are low in cost, long in service life and stable in work, the installing position can be adjusted within a certain range to adjust the gap between the upper shearing plate and the inner wall of the lower cavity, so that the vibration reducing requirements of different building structures are met.

Description

technical field [0001] The invention belongs to the field of anti-shock technology in construction engineering, and in particular relates to a plate type viscous damper, a tuned mass damper and a damper coefficient adjustment method. Background technique [0002] In recent years, due to the development of space structure theory and the application of high-strength materials in the field of construction engineering, large public building structures (such as large venues, hotels, stations, etc.) As a result, the natural vibration frequency of the building structure tends to decrease, and it may be close to or even fall within the frequency range of the pedestrian load. This has led to extensive research on vibration problems such as wind vibration and pedestrian vibration, and passive control technologies such as energy dissipation and shock absorption have been widely used in these building structures. Among them, the tuned mass damper is widely used due to its simple struct...
