Abstract
The invention provides an improved friction damper. The damper comprises an upper main steel plate, a lower main steel plate and a middle steel plate. The upper main steel plate and the lower main steel plate are same in size. The main steel plates are connected with the steel plate through a mixed material cushion layer. Each of four corners of the steel plate is provided with a high strength spring. A baffle plate is arranged near each spring. Under the condition that traditional steel plates have friction between each other, and high strength bolts provide friction forces of different damping ratio, the friction force is provided by the friction of the asphalt rubber mixture in the same layer with the steel plate to improve the dynamic friction property of the damper. At the same time, the high strength spring made of shape memory alloy has one side fixed to the sliding plate to integrally constrain the movement of the main steel plate in four directions, mitigate the effect of sideward motion of earthquake, and enhance the stability of the whole structural system.
Description
Technical field
The invention belongs to civil construction industry earthquake-resistant building cushion technique field, and in particular to one kind is follow-on simply to rub
Wiping type damper.
Background technology
China is vast in territory, different places still in world's plate boundary at, when each plate is with earth movements
Meeting is waited it occur frequently that the earthquake of different earthquake magnitudes.Therefore except the arriving of look-ahead earthquake and in addition to carrying out Aseismic Design, research and development
Various dampers just have very big significance carrying out damping or vibration isolation.And for simplest sliding friction type damper
Speech, generally provides horizontal displacement using the frictional force between steel plate and steel plate, and using high-strength bolt by several blocks of steel plates
It is joined together to provide prestressing force, but bolt easily loosens and causes the damping ratio between steel plate and steel plate to reduce, and is provided
Frictional force it is not enough and do not reach the effect of expected damping.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it is an object of the invention to provide a kind of follow-on Simple friction type resistance
Buddhist nun's device, in conventional steel plates phase mutual friction, in the case that high-strength bolt provides different damping than frictional force, by frictional force by steel plate
The friction of same layer asphalt rubber mixture improves the dynamic of damper providing；Marmem SMA is utilized simultaneously
The high-strength spring one end being fabricated to is fixed on baffle plate one end and is fixed on the steel plate of slip, and the overall upper limit is carried out on four direction
Main steel plate motion processed, mitigates the effect of the sideward motion of earthquake, improves the stability of total system.
To achieve these goals, the technical solution used in the present invention is：
A kind of follow-on Simple friction type damper, including one block of steel plate of upper and lower identical main steel plate and centre, main steel plate
By one layer of mixing sarking junction steel plate, the surrounding of steel plate is respectively provided with a high-strength spring, sets beside each spring
There is baffle plate.
Described high-strength spring is made up of marmem SMA, and in poised state, remains stationary is not stretched not
The state of compression, limits overall large deformation displacement.
Described asphalt rubber grit mixing sarking does horizontal displacement campaign, this layer of mixture pad providing frictional force

Fig. 2 is the front view of the present invention.
Wherein, 1 is main steel plate；2 is steel plate；3 are mixing sarking；4 is high-strength spring；5 is baffle plate.
Specific embodiment
Below in conjunction with the accompanying drawings narration in detail is made to the structural principle and operation principle of the present invention.
As shown in Figure 1, Figure 2, a kind of follow-on Simple friction type damper, including upper and lower identical main steel plate 1 and centre
One block of steel plate 2, main steel plate 1 is respectively provided with a high-strength spring by one layer of mixing junction steel plate 2 of sarking 3, the surrounding of steel plate 2
4, it is provided with baffle plate 5 on the side of each spring 4.
Described high-strength spring 4 is made up of marmem SMA, and in poised state, remains stationary is not stretched not
The state of compression, limits overall large deformation displacement, by made by marmem SMA high-strength tensile spring itself
There is provided in elastic range outside certain strength pull compression, can continue to provide stretching force in non-linear elastic range, and
And can reply in the case of Heat artificially after external force is withdrawn from originally after earthquake terminates, can hold than other general materials
By bigger deformability, it is not easy to damage, the duration is long.
Described asphalt rubber grit mixing sarking 3 does horizontal displacement campaign, this layer of mixture providing frictional force
The ratio of bed course each material can adjust to adapt to the requirement of different anti-seismic earthquake intensity, the mainly viscoplasticity of asphalt rubber adhesive
With the mobility of grit coarse aggregate etc., secondly fully pitch, grit, rubber, catalyst material in construction can also be carried out into weight
Multiple to utilize, material feedstock is easy to get, and reduces building waste.
The present invention operation principle be：
When taphrogeny, top and the bottom structure carries out being moved in horizontal direction with earthquake, and main steel plate 1 is mixed with beneath pitch
The phase mutual friction of compound layer 3 providing the transverse horizontal force of ground floor, the grit lateral flow, drip wherein in asphalt rubber mixture
The materials such as blue or green and rubber play a part of bumper and absorbing shock, the geological process of the mitigation superstructure of entirety.Using asphalt rubber with
The different proportion of the coarse aggregates such as grit come make the damper of different damping ratios will to adapt to the regional of different anti-seismic earthquake intensity
Ask.
Secondly high-strength spring component 4 connects main steel plate 1 and baffle plate 5, and in asphalt rubber mixture 3, this glide lamella occurs
When larger horizontal displacement, the spring 4 of four direction is deforming limiting main steel plate 1；By shape during generation moderate finite deformation
The hyperelastic speciality of memorial alloy itself continues to bear larger deformation in the state of non-resilient, so as to ensure that this second layer is made
Be not in the excessive and situation of unstable failure of skew with whole system is made.And spring 4 can be allowed by the method for heating heating
Elastic stage is come back to, with resettability.
