Abstract
The utility model discloses an antivibration block for a bridge, the main beam of the bridge is installed on the upright post, which is characterized in that the bottom of the main beam has a cushion block of the beam bottom, the main beam protrudes an antivibration block, the top of the upright post has a top cushion block, the top cushion block has a spacing groove, the lower end of the antivibration block lies in the block spacing groove, and the side faces of the lower of the antivibration block has rubber block. The upright post, the top cushion block of the upright post, the cushion block of the beam bottom and the antivibration block together form a composite antivibration block. The antivibration block lies in the spacing groove, the spacing groove can make the spacing action in the transverse and longitudinal directions of the bridge, having landscape effect. The advantages of the antivibration block reside in the spacing, beauty, non effect on the top beam, and operating space for replacing support.
Description
Technical field:
The utility model relates to the stopping means of a kind of bridge Dun Ding, specifically a kind of bridge antidetonation block.
Background technology:
Antidetonation block of the prior art is generally only established horizontal block, does not establish vertical block, can't play the beam action that vertically falls when preventing earthquake, does not also satisfy new earthquake resistant code requirement.Even if be provided with the vertical, horizontal block simultaneously, also be that branch is arranged, structure is scrappy, lacks globality.The block design is comparatively random, the existence of obviously feeling block in appearance, and apparent is lofty, clumsy, diminishes the bridge view.Sometimes stop location has taken the space of back timber, does not stay the better space condition in the future possible bridge maintenance maintenance.
Summary of the invention:
The purpose of this utility model is to provide a kind of bridge antidetonation block, and it is spacing and do not influence back timber and change the bearing operating space to have the vertical, horizontal antidetonation.
To achieve these goals, the technical solution of the utility model is: a kind of bridge antidetonation block, bridge main beam is installed on the column, it is characterized in that being provided with beam heelpiece piece at the bottom of the girder, girder is extended with the antidetonation block, and the column top is provided with the capital cushion block, and the capital cushion block is provided with the block stopper slot, antidetonation block lower end is positioned at the block stopper slot, and antidetonation block lower end side is provided with rubber block.
The utility model adopts column, column top cushion block, beam heelpiece piece and antidetonation block to form compound antidetonation type block together.The antidetonation block is positioned at stopper slot, stopper slot can rise simultaneously direction across bridge and vertical bridge to position-limiting action, combine together with the bridge pier capital, have landscape effect.Advantage of the present utility model be this antidetonation block have the vertical, horizontal antidetonation spacing, attractive in appearance, do not influence back timber and change MULTIPLE COMPOSITE effects such as bearing operating space.
Description of drawings:
Fig. 1 is antidetonation block and pier location graph of a relation
Fig. 2 is the elevation of abutment pier antidetonation block
Fig. 3 is the plan view of abutment pier antidetonation block
Fig. 4 is the elevation of middle pier antidetonation block
Fig. 5 is the plan view of middle pier antidetonation block
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, bridge main beam 1 is installed on the column 2, and bridge is arranged on position A with the antidetonation block.
Fig. 2～Fig. 5 has represented the structural representation of abutment pier and middle pier antidetonation block respectively.1 end of girder, be provided with beam heelpiece piece 3, girder 1 is extended with antidetonation block 4, antidetonation link stopper 4 fuses with beam heelpiece piece 3 in this embodiment, column 2 tops are provided with capital cushion block 5, capital cushion block 5 is provided with block stopper slot 6, antidetonation block 4 lower ends are positioned at block stopper slot 6, and antidetonation block 4 lower end side are provided with rubber block 7.Girder 1 is arranged on column 2 tops by bearing 8, and capital cushion block 5 tops are connected with bearing 8 bottoms, and beam heelpiece piece 3 bottoms are connected with bearing 8 tops, and antidetonation link stopper 4 is arranged on around the bearing 8.
The utility model is by the visual effect of the thickness reduction beam heelpiece piece of attenuate beam heelpiece piece, and the effect of only satisfying leveling gets final product, and forms integral body with the antidetonation block.Whole compound antidetonation block is from facade and column one integrated mass, and is succinctly attractive in appearance.
In the utility model:
1. the capital cushion block is except that reserving the block stopper slot for the antidetonation block being set and in length and breadth to flexible gap size, remainder is made with the column size and flushed, and this cushion block is than common column height.
2. by the interaction of antidetonation block and capital cushion block, play the vertical bridge of bridge to the effect bidirectionally limited with direction across bridge.
The antidetonation block by the beam end stretch to the about 3cm of capital spacing.
4. the antidetonation block of middle pier column is arranged on the suitable bridge of cushion block to both sides, and the block outside flushes with the column plane, and inboard and capital cushion block distance satisfies earthquake displacement; The antidetonation link stopper of abutment pier column is arranged on capital cushion block inboard, and the block outside flushes with the column plane, and inboard and capital cushion block distance satisfies earthquake displacement.
5. antidetonation block thickness should be determined as calculated, generally is no less than 30cm.
6. the lines of antidetonation block can be consistent with column top line bar, with the column coordinating and unifying.
The utility model has the advantage of:
1. the mutually nested mechanism between the block on the block that gets off by the beam end stretch and pier stud top plays vertical, the horizontal antidetonation of bridge, position-limiting action simultaneously, and the vertical, horizontal beam that falls does not take place girder when guaranteeing earthquake, satisfies the new seismic code requirement.
2. this Antivibration block structural configuration compactness, the layout scope does not exceed pier stud top planar range, with whole bridge pier one integrated mass, has preferably bridge landscape effect, has avoided in the past clumsy, the lofty shortcoming of block.
3. the space requirement that the back timber that taken into full account the bearing inspection, needs when changing, former bearing move out and new bearing is installed.
This antidetonation block have the vertical, horizontal antidetonation spacing, attractive in appearance, do not influence back timber and change MULTIPLE COMPOSITE effects such as bearing operating space.
10 is the beam bottom line among the figure, and 11 is column end face line.
