Abstract
The utility model provides a composite damping bracket made of lead-inside rubber for seismic isolation and wind resistance, belonging to the technical field of civil engineering. The utility model is characterized in that the composite damping bracket made of lead-inside rubber for seismic isolation and wind resistance is applied to seismic isolation, vibration damping and wind vibration control in engineering structures, the lead-inside rubber damping bracket is made of rubber and sheet steel by vulcanization under high temperature and high pressure; a lead rod is infused into a reserved hole at a circle centre of the rubber and the lead rod is connected with a upper connecting steel plate and a lower connecting steel plate through a plurality of high strength bolts. The utility model mainly utilizes lead to carry out vibration damping and utilizes the rubber material to provide composite damping force. The utility model can be utilized in damping control and wind vibration control in engineering structures. The utility model has the advantages of easy material obtaining, easy mass production, convenient mounting and dismounting, low cost, adjustable damping force, good damping effect and a wide application range.
Description
Technical field
The utility model is a kind ofly to be used in civil engineering structure to reduce that wind shakes and the damper of earthquake sheet.
Background technology
The lead damper of prior art is a kind of simple structure, easy, the well behaved damper of drawing materials, can and isolator (as neoprene bearing etc.) be used, form shock isolation system, be applied to build in the shock insulation and vibration damping energy dissipating with bridge.At present existing polytype lead damper mainly contains: (1) lead shear damper, as Fig. 1; (2) lead extrusion damper is as Fig. 2; (3) cylindrical damper is as Fig. 3; (4) special-shaped lead damper etc. is as Fig. 4.The some of them damper is used in a lot of engineerings, effectively carries out the passive energy dissipation of structure.
There is following problem in existing lead damper: energy consume mechanism that (1) is single and material power consumption; (2) damping that is provided and initial stiffness are limited, and for satisfying actual requirement of engineering, damper must be sufficiently large; (3) be difficult for forming the typing series of products; (4) be mainly used in the wind control of shaking, it is less to be used for the Seismic Response Control damping force, and effect is not good enough.
Summary of the invention
The purpose of this utility model provides a kind of solution of reconciling contradiction between structural seismic and the wind resistance, is used to reduce that wind shakes and the plumbous heart type rubber vibration isolation wind resistance composite damping bearing of earthquake sheet.
The utility model by rubber, steel sheet, connect steel plate up and down and the plumbous heart is formed, rubber, steel sheet, connect steel plate up and down, be sulfided into one by HTHP, circular hole is reserved at the center, the plumbous heart can pour in the preformed hole, after sulfuration as shown in Figure 5.
Description of drawings
Fig. 1 is a lead shear damper;
Fig. 2 is a lead extrusion damper;
Fig. 3 is a cylindrical damper;
Fig. 4 is special-shaped lead damper;
Fig. 5 is the structural representation of the plumbous heart type of the utility model rubber vibration isolation wind resistance composite damping bearing;
In the accompanying drawing: 1 is plumbous; 2 for connecting steel plate; 3 are supporting; 4 is extrusion mouth; 5 is rubber; 6 is steel sheet; 7 is connecting bolt.
The specific embodiment
The purpose of this utility model is achieved in that a kind of lead damper is sulfided into one by rubber, steel sheet by HTHP, in the hole that the center of circle is reserved, pour into lead rod, and by high-strength bolt be connected steel plate up and down and connect, connect steel plate up and down and be connected with support or structural pre-embedded steel slab by bolt.
The utility model is mainly to be to utilize the distortion of lead material to carry out passive energy dissipation, also adds the damping effect of rubber simultaneously.It is to be sulfided into one by rubber, steel sheet by HTHP, pours into lead rod in the hole that the center of circle is reserved, and by high-strength bolt be connected the steel plate connection up and down.The size of plumbous core diameter, the thickness of elastomeric material and steel sheet number and thickness calculate by specific requirement to be determined.Damper by bolt be connected steel plate up and down and connect, be connected with structure by pre-embedded steel slab again, can be installed on the styletable position of structure, also can be connected with support (chevron shaped or X type or chevron shaped) in the structure by connector.
The advantage of this NEW Pb heart type rubber vibration isolation wind resistance composite damping bearing is: (1) damper structure is simple, draw materials easily, Simple for production, be easy to make standard component and produce by batch; (2) utilize two kinds of energy consume mechanism power consumptions, can be by plumbous core diameter size Damping adjusting; (3) can be used for simultaneously wind resistance shakes and earthquake; (4) planar any direction produces relative motion, alleviates and Vibration from all directions; (5) assembling, dismounting, replacing are easily.
Claims (2)
1. one kind by the plumbous heart, rubber, steel sheet, connect the plumbous heart type rubber vibration isolation wind resistance composite damping bearing that steel plate, bolt etc. are constituted up and down, it is characterized in that damping element by rubber, steel sheet, connect steel plate up and down and formed, and be sulfided into one by HTHP, pour into the plumbous heart in the hole that the center of circle is reserved, damping element is connected by bolt with connector up and down.
2. plumbous heart type rubber vibration isolation wind resistance composite damping bearing as claimed in claim 1 is characterized in that damping element leans on bolt to be connected with support or structure.
