Description
Technical field:
The present invention relates to the aseismatic bearing structure and the device of bridge and other building, a kind of hyperboloid spheroidal bearer of shock absorption and insulation.
Background technology:
In the design of bridge and other building structure, often to consider the influence of earthquake to engineering structures.Bearing not only will be given substructure with the Load Transfer on structure tops such as bridge, building, and absorb rotation, displacement as the important component of bridge and other building structure, also should possess certain function of shock insulation that subtracts.
At present, the domestic antishock device that is used for bridge and other building mainly contains lead-rubber aseismatic bearing, polyurethane spring spherical bearing and big friction factor aseismatic bearing etc., all has weak point.
The lead-rubber aseismatic bearing, reason such as relatively poor owing to durability, that supporting capacity is little, environment pollution is serious will be eliminated gradually;
The polyurethane spring spherical bearing, because poor durability, to bend the back displacement little, physical dimension is big again, is subjected to certain limitation in the use;
Big friction factor aseismatic bearing, because it is bigger to be delivered to the earthquake lateral force of substructure, only relies on the friction pair earthquake energy of big friction factor, and restoring force can not be provided, can only use as a kind of anti-seismic construction, and actual anti seismic efficiency does not satisfy the structure designing requirement yet.
Summary of the invention:
In order to overcome the defective of above-mentioned existence, the invention provides a kind of hyperboloid spheroidal bearer of shock absorption and insulation, with solve press on the engineering have good endurance, supporting capacity height, size little, bend the problem that the back displacement is big, bend the antidetonation shock attenuation bearing of high comprehensive performances such as back rigidity is suitable, satisfying has the bridge of shockproof requirements and the demand of other building.
The present invention adopts following technical scheme to solve:
Described hyperboloid spheroidal bearer of shock absorption and insulation, it is made up of upper base plate, middle seat board, following seat board, slide plate, and the concave spherical surface welding of the upper base plate of this bearing pastes sphere stainless steel slide plate, and the upper base plate concave spherical surface outside is by the fixedly connected spacing ring of shearing bolt; Be inlaid with the tetrafluoro slide plate on the last convex surface of middle seat board, the same welding of the following convex surface of middle seat board pastes sphere stainless steel slide plate; Be inlaid with the tetrafluoro slide plate on the concave spherical surface of following seat board.
Described hyperboloid spheroidal bearer of shock absorption and insulation, the concave spherical surface of its upper base plate are the long radius sphere.
Described hyperboloid spheroidal bearer of shock absorption and insulation, its tetrafluoro slide plate are the filled polytetrafluoroethylene composite sandwich plate that burst is inlayed.
Described hyperboloid spheroidal bearer of shock absorption and insulation is provided with the dust seal skirt between its upper base plate and the following seat board.
Owing to adopted technique scheme, the present invention to have following good effect:
On the one hand, under normal circumstances, hyperboloid spheroidal bearer of shock absorption and insulation can play the effect of common bearing, and the upper load that is about to bridge or other building passes to substructure equably, absorbs superstructure simultaneously because of creeping and caused telescopic displacement of variations in temperature and rotation; On the other hand, when earthquake takes place, can play and subtract function of shock insulation,, reduce or isolate the influence of earthquake bridge or structure by special device.
Technically, the invention solves China for a long time lack good endurance, restoring force strong, bend the big aseismatic bearing of back displacement for a difficult problem of using on the engineering;
From economically, use hyperboloid spheroidal bearer of shock absorption and insulation, structure is taken precautions against natural calamities, especially the antidetonation of bridge has very important significance.
The characteristics of hyperboloid spheroidal bearer of shock absorption and insulation are: simple in structure, the antidetonation principle is clear and definite, does not contain easily aging materials such as rubber, good endurance.
Description of drawings:
Fig. 1 is the structural representation of hyperboloid spheroidal bearer of shock absorption and insulation.
Among the figure: 1-shearing bolt, 2-spacing ring, 3-sphere stainless steel slide plate, 4-tetrafluoro slide plate, seat board among the 5-, 6-upper base plate, 7-dust seal skirt, seat board under the 8-.
The specific embodiment:
Hyperboloid spheroidal bearer of shock absorption and insulation is on the basis of common spherical bearing, replaces the planar friction pair with long radius sphere friction pair, and shearing bolt is set and a kind of novel bearing that forms.Be mainly used in bridge and other building of shockproof requirements.
As shown in fig. 1, hyperboloid spheroidal bearer of shock absorption and insulation mainly is made up of upper base plate (6), middle seat board (5), following seat board (8), sphere stainless steel slide plate (3), tetrafluoro slide plate (4), shearing bolt (1), spacing ring (2) and dust seal skirt several parts such as (7).The concave spherical surface welding of upper base plate (6) pastes sphere stainless steel slide plate (3), and the upper base plate concave spherical surface outside is by the fixedly connected spacing ring of shearing bolt (1) (2).The last convex surface of middle seat board (5) is inlayed tetrafluoro slide plate (4), form sliding friction pair with the sphere stainless steel slide plate (3) of upper base plate concave spherical surface, the same welding of the following convex surface of middle seat board (5) pastes sphere stainless steel slide plate (3), form sliding friction pair with the tetrafluoro slide plate of inlaying on the concave spherical surface of following seat board (8) (4), the filled polytetrafluoroethylene composite sandwich plate that tetrafluoro slide plate (4) adopts burst to inlay.Adopt dust seal skirt (7) to seal between upper base plate of bearing (6) and the following seat board (8).
Hyperboloid spheroidal bearer of shock absorption and insulation adopts long radius sphere friction pair to replace the planar friction pair on common spherical bearing top, make when earthquake takes place, conversion and friction consumed energy by kinetic energy and potential energy prolong the vibrations cycle, thereby reduce the influence of earthquake to structure; The composite intermediate layer sliding plate with filled polytetrafluoroethyland that adopts burst to inlay replaces conventional bearing and uses the pure polytetrafluoroethylene (PTFE) slide plate of pasting, and has improved anti-pressure ability, has reduced friction factor, has reduced wear rate and compression creep; On the concave, convex sphere, replace common spherical bearing durionise layer on protruding sphere with pasting the stainless steel slide plate, friction, the polishing machine of assurance friction pair stablized constant, the application life of having improved bearing; The method that the tetrafluoro standard slide plate of employing different surfaces state carries out mixing can accurately be adjusted the friction factor size by subtracting the shock insulation requirement.
The shock insulation principle that subtracts of hyperboloid spheroidal bearer of shock absorption and insulation is, when earthquake generation and lateral force surpassed set-point, shearing bolt was cut off, and the cross spacing constraint of bearing is disengaged, long radius sphere friction pair laterally can be free to slide, thereby the kinetic energy that earthquake is produced is converted to potential energy.Simultaneously, in slipping, frictional resistance consumes a part of earthquake energy again.Like this, reach the effect of damping, prolonged earthquake period; And potential energy can form restoring force, and bearing is resetted.
