Abstract
The utility model discloses a damping type anti-beam-falling device for single-column piers of highway bridges, which comprises a stop block, a beam body and single-column piers, wherein the beam body is arranged on the single-column piers through a base, and the stop block is arranged at the bottom of the beam body and at the two sides of the single-column piers; the single-column pier bridge is easy to be fallen when the major earthquake or other displacement accidents are generated on the bridge body, the utility model discloses a girder that falls is prevented to highway bridge single-column pier damping type prevents falling roof beam device, avoids the accident to produce danger factor or produce bigger economic loss to the personnel under the bridge on the bridge.
Description
Technical Field
The utility model belongs to highway, municipal bridge engineering are a roof beam device is prevented falling by highway bridge single-column pier damping type particularly.
Background
The single-column pier has the characteristics of simplicity, attractiveness, good under-bridge visual effect, investment saving and the like, is widely used in the design of municipal roads and expressway intercommunicating ramps, and is mostly not provided with a beam falling prevention device. However, in recent years, the beam body is frequently dropped due to an earthquake or other displacement accidents on the beam body. Simultaneously, single column mound top size is less, and the space should not set up prevents the roof beam device that falls, and single column mound bridge easily takes place to fall the roof beam when shaking greatly or other produce displacement class accidents to the roof beam body, produces risk factor or produces economic loss to the personnel under the bridge on the bridge.
Disclosure of Invention
An object of the utility model is to the not enough that exists among the above-mentioned prior art, provide a public road bridge single column mound damping type prevents roof beam device that falls, prevents the roof beam device that falls through at the beam bottom design, realizes strengthening the security performance when single column mound uses, prevents the purpose of roof beam that falls.
The utility model discloses a following technical scheme realizes: the utility model provides a roof beam device is prevented falling by highway bridge single column mound damping type, includes dog, the roof beam body and single column mound, through the base installation roof beam body on the single column mound, in the bottom of the roof beam body, the both sides of single column mound, set up the dog.
Preferably, the stop block consists of four vertical steel plates which are parallel to each other in pairs and vertical to the beam bottom and a bottom horizontal steel plate; the beam body bottom is provided with pre-buried steel sheet, and vertical steel sheet passes through bolt bush and connects in the pre-buried steel sheet of beam body bottom.
Preferably, the size of the single-column pier is 1.4-2.0 m, the size of the beam body is 10.5m, and the length, width and height of the stop block are 0.8 multiplied by 0.7 m.
The utility model discloses a single-column mound prevents beam falling device design can be good solution single-column mound problem of falling the roof beam, not influence single-column mound service condition, not increase by a large amount under the circumstances such as lower part dead weight for the single-column mound has more the advantage in town road, highway ramp design, use.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
As shown in fig. 1-2, a damping type anti-falling beam device for single-column piers of a highway bridge comprises stop blocks 1, a beam body 2 and single-column piers 3, wherein the beam body 2 is installed on the single-column piers 3 through a base 8, and the stop blocks 1 are arranged at the bottom of the beam body 2 and on two sides of the single-column piers 3.
As shown in fig. 3-4, the stop block 1 is composed of four vertical steel plates 5 and a bottom horizontal steel plate 6 which are parallel to each other in pairs and perpendicular to the beam bottom; the bottom of the beam body 2 is provided with a pre-buried steel plate 4, and the vertical steel plate 5 is connected to the pre-buried steel plate 4 at the bottom of the beam body 2 through a bolt sleeve 7.
Furthermore, the size of the single-column pier 3 is 1.4-2.0 m, the size of the beam body 2 is 10.5m, and the length, the width and the height of the stop block 1 are 0.8 multiplied by 0.7 m.
The above-mentioned example is only the individual example of the utility model application, and does not limit the scope of the utility model application, any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model all belong to the protection scope of the utility model.
