Embodiment
The embodiment of the utility model is described in further detail below in conjunction with attached drawing.
Shown in Figure 1, the utility model embodiment provides a kind of bridge with detachable Antivibration block, and bridge includes
Bridge pier 1 and crossbeam 2, the bridge further include bearing 3, which is removably arranged between the bridge pier 1 and crossbeam 2, and on bridge pier 1
Equipped with a boss 101, bearing 3 is detachably arranged on the boss 101, which is fixed on bridge pier 1, it is preferred that bearing 3
A bracket 5 is equipped between crossbeam 2, which is fixed on crossbeam 2, and bracket 5 is detachably connected with bearing, by setting one
Bracket 5, can reduce the height of bearing 3 used, that is, reduce the material that bearing 3 uses, so that the cost of replacing time 3 is reduced,
Bearing 3 can also be avoided to directly act on crossbeam 2, so that damage when reducing replacing time 3 to crossbeam 2, increase crossbeam 2
Service life, is equipped with one second backing plate 7, which can reduce bearing 3 and bracket 5 is direct between the bracket 5 and bearing 3
Damage caused by contact, increases the service life of bracket 5.
Antivibration block 4 is provided with boss 101 referring to shown in Fig. 1 to Fig. 3, being additionally included in, wherein, Antivibration block 4
I-shaped or box is welded into using steel plate, when using I-shaped Antivibration block 4, towards boss when which is set
101 section is I-shaped, can preferably play antihunt action, and the Antivibration block 4 is equipped with ribs 401, can strengthen
The intensity of Antivibration block 4, improves the shock resistance of the Antivibration block 4, which is less than boss 101 with a distance from bridge pier 1
Height, the Antivibration block 4 can be made to act on boss 101 when bridge shakes so as to playing the role of antidetonation, extend the bridge
The service life of beam, Antivibration block 4 are removably arranged on crossbeam 2, wherein, 4 top surface of Antivibration block is equipped with multiple first mounting holes 41,
