At present, field of structural design proposes a kind of design based on performance method, and wherein the most basic realization means is at new building or needs to install energy-consuming shock absorber in addition in the building of strengthening reconstruction.Viscous damper, as the one of structure passive vibration control, by the consumption of its viscous damping energy or plastic strain energy, reduces the vibrational energy passing to building, thus reduces the reaction of structure under wind and geological process.The advantage of viscous damper is: make processing simple; Applicability is strong; Damper itself does not need the input of extra power; Hysteresis Behavior is stablized.Its weak point is: the control that can not adjust damper according to the characteristic of earthquake response; Be difficult to recover after process adds large deformation, the damper that need more renew.
Summary of the invention
The purpose of this utility model is to provide one can to reset viscous-frcition damper, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: one can reset viscous-frcition damper, it is characterized in that, be arranged on the middle connecting plate in the middle of described damper and be arranged on the front junction plate of middle connecting plate both sides and rear junction plate, and successively through the reset bolt of front junction plate, middle connecting plate, rear junction plate, between described middle connecting plate and front junction plate and rear junction plate, a part of region is bonded as entirety by viscous material layer, and another part arranges the friction steel plate with viscous material layer same thickness.
Further, described forward and backward junction plate is T-steel plate, L-type steel plate or rectangular steel plates.
Further, described viscous material layer is high decay rubber series viscoelastic material.
Further, correspondence position has the identical bolt hole of size for described middle connecting plate, front and back junction plate, viscous material layer, friction steel plate.
Further, described viscous material layer adopts rubber and steel plate to bond sulfuration process secure bond respectively with described subregion middle connecting plate and front and back junction plate, and by reset bolton.
Further, described friction steel plate is connected by reset bolt with the middle connecting plate of described subregion and front and back junction plate and fastening respectively.
Further, described reset bolt from side through the perforate front junction plate, middle connecting plate, rear junction plate and viscous material layer and friction inner panel, fastening at opposite side nut.
Further, described reset bolt inner core adopts steel bolt inner core, and inner core is peripheral to be made up of two-layer rubber sleeve and two-layer marmem cover interval, and rubber sleeve is combined by sulfuration and inner core, marmem cover.
Compared with prior art, the beneficial effects of the utility model are: this viscous-frcition damper that can reset is resetted to generation distortion by reset bolt, when producing relative displacement between junction steel plate, marmem cover produces with rubber sleeve and is out of shape, rubber sleeve distortion heat release, marmem returns to the original form at an elevated temperature, thus produce the effect resetted, and surrender can be repeated and do not produce permanent deformation, even if also can set back under making this viscous-frcition damper that can reset have passed through the situations such as larger earthquake, do not need the damper more renewed, this viscous-frcition damper that can reset can consume energy under all vibration conditions, namely under low frequency vibration condition, because reset bolt presses each junction plate, vibrate and carry out consumed energy mainly through friction between friction steel plate and each junction plate, and under dither condition, then consume energy mainly through viscous material layer, the shear strain of reset bolt inner rubber.This viscous that can reset-frcition damper simple structure, manufacture, installation and maintenance conveniently, can according to concrete damping sizes, and installation site adjusts, and meets design of building structures and Functional Requirement.
