Abstract
The invention provides a compound energy consumption one-way bridge support with a simple construction, convenient machining and stable performance. By using the characteristics of curve and tensile deformation of soft steel curved beams, the support mainly comprises a lower basin (1), an upper basin (2), a spherical cap lining plate (3), a curved beam (4), anchored steel sleeves (9), and anchor bolts (10). The spherical cap lining plate (3) is positioned between the upper basin (2) and the lower basin (1), and is concentrically matched with the upper basin (2). The upper basin (2) and the lower basin (1) are provided with four anchored steel sleeves (9) and the anchor bolts (10) respectively. The curved beam (4) is symmetrically arranged between the upper basin (2) and the lower basin (1), and two ends of the curved beam (4) are hinged with the spherical lining plate (3) and the lower basin (1) respectively. The support allows for the longitudinal bridge deviation between the upper basin and the lower basin, while the transverse bridge deviation is restrained. When the longitudinal bridge deviation between the upper basin and the lower basin occurs, the energy of the system is consumed through the deformation (curve, stretch) of the curved beams to achieve the aim of reducing the vibration; therefore, the conventional support has the function of energy consumption.
Description
Technical field
The present invention is a kind of compound energy consumption one-way bridge support device, as the one-way support in the bridge engineering, and can play the effect of energy-dissipating and shock-absorbing (shaking) to bridge.
Background technology
Energy-dissipating and shock-absorbing (shaking) technology is a kind of effective structure control technology, and it reduces the response of structure under dynamic load function by in the appropriate location of structure energy-dissipating and shock-absorbing (shaking) device being installed with this.At present, very wide both at home and abroad to the research of energy-consumption damper monomer, but less to not only satisfying the structure function of use but also having device research and development of energy dissipation behavior.Develop and exploitation compound energy consumption device, produce the damper product of function admirable, have important economic benefit and social benefit.The present invention proposes a kind of compound energy consumption one-way bearing that is used on the bridge, and this bearing can satisfy the requirement of bridge supporting, has energy dissipation behavior preferably simultaneously.
Summary of the invention
Technical problem: the energy dissipation behavior of mild steel is compound to bridge pad, make traditional bridge pad have energy dissipation behavior, improve present bridge pad and all be in the state that separates with damper production, installation.Conventional bridge pad generally is divided into one-way support and bilateral support, and the former is generally at direction across bridge with supporting vertically is provided; The latter is generally only vertically providing supporting.The present invention according to one-way support at vertical bridge to characteristics that can free off normal, a kind of simple structure, easy to process, stable performance, compound energy consumption one-way bridge support that energy dissipation capacity is strong are proposed.
Technical scheme: compound energy consumption one-way bridge support of the present invention mainly comprises following basin, goes up basin, spherical crown liner plate, curved beam, anchoring steel bushing, anchor bolt; The spherical crown liner plate and mates with last basin is concentric between last basin and following basin; Last basin respectively is provided with four anchoring steel bushings and anchor bolt with following basin; Curved beam is symmetrically arranged between spherical crown liner plate and the following basin, and its two ends are hinged on respectively on spherical crown liner plate and the following basin.
Described curved beam is symmetrically arranged in down on the bearing pin of basin and spherical crown liner plate, and the axis of curved beam is variable curvature or variable section structure.
Described curved beam material is a low-yield mild steel.
Described spherical crown liner plate respectively and last basin, down the smooth polyethylene tetrafluoro plate that contains elastic seal ring is set between the basin; Bearing is provided with spacing on direction across bridge.
The very little polyethylene tetrafluoro plate of friction factor all is set between spherical crown liner plate and upper and lower basin can reduces horizontal frictional force between upper and lower basin, be beneficial to indulge bridge up and down between basin to slip; The spherical crown liner plate can allow to take place between basin up and down certain corner displacement.Last basin is fixed by the beam body of crab-bolt and bridge; Following basin is fixed by crab-bolt and Dun Ding.Following basin edge direction across bridge is provided with block, to limit the off normal that occurs direction across bridge between upper and lower basin; The curved beam two ends all adopt bearing pin to be connected with upper and lower basin, and the bearing pin end is provided with stop nut, with the relative bearing pin slippage of restriction curved beam.
Bridge construction is subjected to dynamic load function, occur between the upper and lower basin of bearing vertical bridge to relative motion repeatedly, plane inner bending, stretcher strain will take place in the curved beam that causes being connected between spherical crown liner plate and following basin.Curved beam consumption systems energy in this process reduces the vibration of beam body.When the relative motion displacement reached certain numerical value, the vertical bridge of following basin off normal between spacing effectively restraint beam body in edge and bridge pier surpassed the displacement that limits.
By adjusting the initial stiffness that rigidity in the curved beam face can change compound energy consumption one-way bridge support, to reach designing requirement, its energy dissipation behavior influences parameter and mainly comprises curved beam material characteristic, curved beam cross section property and curved beam axis curvature.
Beneficial effect: the compound energy consumption one-way bridge support that the invention provides a kind of simple structure, easy to process, stable performance.Utilize the characteristic of the bending of mild steel curved beam, tension and compression deformation power consumption, four curved beams of symmetric arrangement between bridge pad spherical crown liner plate and following basin.Occur between the upper and lower basin of bearing vertical bridge to off normal the time, all can be out of shape the energy that comes consumption systems, to reach the purpose of vibration damping by curved beam.With respect to traditional one-way bridge support, this one-way bridge support simple structure, energy dissipation capacity is strong, has both satisfied the requirement of the vertical carrying of bearing, has energy dissipation behavior again, can be widely used in the bridge engineering.
