Abstract
The utility model discloses a bridge-used vibration damping enhanced rigid hinge support, which comprises an upper support plate (1), a spherical crown lining plate (2) and a lower support plate (3), from upper to down. A spherical sliding plate (4) is arranged between the spherical crown lining plate (2) and the lower support plate (3); a plane sliding plate (8), a middle steel lining plate (9) and a vibration damping rubber cushion (10) are arranged between the upper support plate (1) and the spherical crown lining plate (2) from up to down; and the middle part of the middle steel lining plate (9) is welded with a shearing force tenon (11), the lower end of which is resisted against the middle part of the spherical crown lining plate (2) so as to form a slot. The utility model is smartly designed, has low cost, can enhance the function of vibration damping due to the vibration damping rubber cushion, can decrease the peak stress on the rigid hinge support and can promote the safety of the rigid hinge and the support structure.
Description
Technical field
The utility model belongs to the bridge technology field, relates to a kind of reinforced rigid hinged support of vibration damping that is used for bridge concretely.
Background technology
The good bridge rigidity hinge that continues has adopted the mode of the nested little steel case beam of big steel case beam, and rigidity hinge special carrier (as shown in Figure 2) is set at big or small each bonding surface of steel case beam, the rigidity hinge mainly is made up of big case beam 13, little case beam 14 and bearing 15, forming rigidity hinge to direction by the mode that connects the big case beam 13 in two ends, the left and right sides with little case beam 14 along bridge, its medium and small case beam 14 left ends are fixed in the cavity of the big case beam 13 in the left side, and right-hand member stretches into the inner chamber of the big case beam 13 in the right and supports big case beam 13 by bearing 15.Have relative to the slip and the effect of rotating owing to go up lower support plate in the bearing 15, make the big case beam 13 at two ends, the left and right sides form similar hinged form.Therefore this rigidity hinge has the vertical relative displacement that discharges the girder generation of span centre both sides, vertical, the laterally relative deformation and relatively rotating at constraint girder two ends, and bearing 13 is very crucial parts in cutting with scissors as rigidity, and its support, effectiveness in vibration suppression are particularly important.Present bearing mainly comprises upper bracket plate 1, spherical crown liner plate 2 and lower support plate 3, is provided with sphere slide plate 4 between spherical crown liner plate 2 and the lower support plate 3, and it is not good that total is that rigidity contacts its effectiveness in vibration suppression substantially.
The utility model content
The purpose of this utility model has been to provide a kind of reinforced rigid hinged support of the vibration damping that is used for bridge that can strengthen effectiveness in vibration suppression.
The technical solution of the utility model is as follows:
A kind of reinforced rigid hinged support of vibration damping that is used for bridge, comprise upper bracket plate, spherical crown liner plate and the lower support plate of arranging from top to bottom, be provided with the sphere slide plate between described spherical crown liner plate and the lower support plate, be disposed with plane slide plate, middle steel liner plate and rubber damping pad from top to bottom between described upper bracket plate and the spherical crown liner plate, middle part at described middle steel liner plate is welded with the shearing trip, and the lower end abutment of this shearing trip is in the groove that described spherical crown liner plate middle part forms.
When adopting said structure to install, the design of rubber damping pad can be played the effect of strengthening vibration damping, reduce rigid hinged support and bear spike stress, improved of the safety of rigidity hinge with seat structure, steel liner plate can produce shearing force in the horizontal direction to rubber damping pad in the middle of driving when the plane slide plate takes place to slide simultaneously, for avoiding rubber damping pad to be subjected to shearing force tired impaired, the purpose of design of shearing trip is that the shearing force that middle steel liner plate is suffered is directly delivered to the spherical crown liner plate by the shearing trip in this structure, reduced the suffered shearing force of rubber damping pad greatly, guaranteed that bearing slides freely.
Be provided with sealing ring in the slide plate outside, plane between upper bracket plate and the middle steel liner plate and the sphere slide plate outside between spherical crown liner plate and the lower support plate.
The design of sealing ring can be played and reduce the pollution of external environment dust to sled surface; Influence shuffle effect.
Beneficial effect: the utility model is skillfully constructed, and cost is low, and the effect of strengthening vibration damping is played in the design of rubber damping pad, reduces rigid hinged support and bears spike stress, has improved the safety of rigidity hinge with seat structure.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure principle chart of rigidity hinge in the background technology.
The specific embodiment
Embodiment: as shown in Figure 1: a kind of reinforced rigid hinged support of vibration damping that is used for bridge, comprise upper bracket plate 1, spherical crown liner plate 2 and the lower support plate 3 of arranging from top to bottom, be provided with sphere slide plate 4 between described spherical crown liner plate 2 and the lower support plate 3, be disposed with plane slide plate 8, middle steel liner plate 9 and rubber damping pad 10 between described upper bracket plate 1 and the spherical crown liner plate 2 from top to bottom, middle part at described middle steel liner plate 9 is welded with shearing trip 11, and the lower end abutment of this shearing trip 11 is in the groove that described spherical crown liner plate 2 middle parts form.
Be provided with sealing ring 12 in plane slide plate 8 outsides between upper bracket plate 1 and the middle steel liner plate 9 and sphere slide plate 4 outsides between spherical crown liner plate 2 and the lower support plate 3.
Claims (2)
1. reinforced rigid hinged support of vibration damping that is used for bridge, comprise the upper bracket plate of arranging from top to bottom (1), spherical crown liner plate (2) and lower support plate (3), be provided with sphere slide plate (4) between described spherical crown liner plate (2) and the lower support plate (3), it is characterized in that: be disposed with plane slide plate (8) from top to bottom between described upper bracket plate (1) and the spherical crown liner plate (2), middle steel liner plate (9) and rubber damping pad (10), middle part at described middle steel liner plate (9) is welded with shearing trip (11), and the lower end abutment of this shearing trip (11) is in the groove that described spherical crown liner plate (2) middle part forms.
