Abstract
The utility model belongs to the technology field of a bridge bearing and discloses a bridge seismic basin-shaped bearing, of which the main technology is characterized in that the utility model comprises a basin base, a basin core and a basin cover, wherein, an upper edge of the basin base is provided with a correspondent square basin edge connected with the basin base as a whole; an edge of the basin cover is provided with a downward baffle, which is arranged at the basin edge and bends inwards to form a supporting plate along the downward direction; a guiding block with an arch-shaped cross section is positioned on the supporting plate; the two sides of a bottom surface of the basin edge is provided with a curved surface groove matched with an upper surface of the guiding block, and the guiding block is arranged in the interior of a groove. The utility model solves the problem that the present bridge seismic basin-shaped bearing can not reduce the damage caused by the force in the vertical direction and can be applied to the seismic resistance of the highway and railway bridges.
Description
Technical field
The utility model belongs to the bridge pad technical field, relates in particular to a kind of bridge earthquake resistance pot bearing.
Background technology
Along with the development of transportation and the raising of construction standard, bearing not only plays a supportive role in bridge and engineering, and should have vibration damping, resistance to plucking, release moment of flexure, resist displacement or the effect of displacement is arranged.The bearing that uses is provided with block rubber and is positioned at this frictional damping pair above block rubber in basin core bottom at present, can resist 20% of bearing capacity for the horizontal direction active force, still, does not have effect substantially for the vertical direction active force.Seismic wave is divided into vertical direction seismic wave and horizontal direction seismic wave, and the active force of generation comprises vertical direction active force and horizontal direction active force equally, because bearing can not be resisted the vertical direction active force, thereby bridge is damaged.
The utility model content
The purpose of this utility model just provides a kind of bridge earthquake resistance pot bearing that can resist the vertical direction active force that has.
To achieve these goals, the technical solution adopted in the utility model is: comprise pot base, basin core and basin lid, be provided with the square basin edge that is connected as a single entity with it in the upper edge of described pot base, described basin lid edge is provided with downward baffle plate, this baffle plate is positioned at described basin and bends inwards into supporting plate along the below, being placed with the cross section on described supporting plate is arc guide pad, be provided with the curved surface groove that mates with the guide pad upper surface in the both sides, bottom surface on described basin edge, guide pad is placed in this groove.
Its additional technical feature comprises: be provided with block rubber and be positioned at this frictional damping pair above block rubber in described basin core bottom; Between described basin core side and pot base, have the gap, in this gap, be provided with damped ring; Between described basin core upper surface and basin lid, be placed with the PTFE plate.
Bridge earthquake resistance pot bearing provided by the utility model compared with prior art, have the following advantages: one, because described basin lid edge is provided with downward baffle plate, this baffle plate is positioned at described basin and bends inwards into supporting plate along the below, being placed with the cross section on described supporting plate is arc guide pad, be provided with the curved surface groove that mates with the guide pad upper surface in the both sides, bottom surface on described basin edge, guide pad is placed in this groove, when bridge runs into the vertical direction active force, guide pad can rotate in groove under the effect of power, the vertical direction active force is played cushioning effect, reduced because of of the breaking-up of vertical direction active force to bridge; Its two owing to be provided with block rubber and be positioned at this frictional damping pair above block rubber, and in the gap between described basin core side and pot base damped ring is arranged in described basin core bottom, reduced the damage that bearing causes because of the horizontal direction active force.
Description of drawings

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of guide pad.
The specific embodiment
The structure of the bridge earthquake resistance pot bearing that the utility model is provided below in conjunction with accompanying drawing is described in further details.
As depicted in figs. 1 and 2, the bridge earthquake resistance pot bearing that provides for the utility model comprises pot base 1, basin core 2 and basin lid 3, be provided with the square basin that is connected as a single entity with it in the upper edge of pot base 1 along 4, basin covers 3 edges and is provided with downward baffle plate 5, baffle plate 5 is positioned at basin and bends inwards into supporting plate 6 along 4 belows, be placed with guide pad 7 as shown in Figure 3 on the supporting plate 6, guide pad 7 cross sections are arc, be provided with the curved surface groove 8 with guide pad 7 upper surfaces coupling in the both sides, bottom surface of basin along 4, guide pad 7 is placed in the groove 8.
In order to prevent of the infringement of horizontal direction active force, be provided with block rubber 9 in basin core 2 bottoms and be positioned at this frictional damping pair 13 above block rubber 9 bridge; Between the side of basin core 2 and pot base, have gap 10, in the gap, be filled with damped ring 11; Between basin core upper surface and basin lid, be placed with PTFE plate 12.
Claims (4)
1. bridge earthquake resistance pot bearing, comprise pot base, basin core and basin lid, it is characterized in that: be provided with the square basin edge that is connected as a single entity with it in the upper edge of described pot base, described basin lid edge is provided with downward baffle plate, this baffle plate is positioned at described basin and bends inwards into supporting plate along the below, being placed with the cross section on described supporting plate is arc guide pad, is provided with the curved surface groove that mates with the guide pad upper surface in the both sides, bottom surface on described basin edge, and guide pad is placed in this groove.
