Description

Bridge pier of overhead bridge

Technical Field

The invention relates to the field of bridge protection, in particular to an overhead bridge pier.

Background

Highway overpass sets up on ground road, be used for the vehicle reposition of redundant personnel, promote vehicle circulation speed, overpass sets up and needs to use a large amount of piers at ground road, these piers support on road is subaerial, because road subaerial car flow is big, these naked piers are very easily by the vehicle striking, although the pier is bulky, but very necessary to the protection of pier, large vehicle's impact degree is very big, if not protect, then make the bearing capacity of pier change after the striking of a time very probably, bring unpredictable danger. Furthermore, since the pier is bulky, the vehicle is damaged to a very large extent when it is inadvertently bumped against the pier due to an accident. In the prior art, people wrap a spongy soft layer or other protective materials on the outer wall of the pier, but the attractiveness of the pier is seriously affected by the method, the buffering effect is very poor, the vehicle is likely to be bounced off after being impacted, the safety performance is not good, and no functional effect is generated except for collision prevention.

Detailed Description

As shown in fig. 1 and fig. 2, this elevated bridge pier, including installing support column 5 on bridge pier 1, the lower extreme open-ended assembly chamber about one is seted up to the centre of support column 5, be provided with one section external diameter on bridge pier 1 and be less than the assembly section of bridge pier, the assembly chamber is installed on the assembly section, a support ring 2 is installed respectively to the upper and lower end of support column 5, support ring 2 extends and with 1 lateral surface parallel and level of bridge pier towards 1 outside end of bridge pier, form a cushion chamber 7 between upper and lower support ring 2, install many spinal branchs vaulting pole 3 in the cushion chamber 7, many spinal branchs vaulting pole 3 are the annular and set up in the cushion chamber, two spinal branchs vaulting pole 2 about many spinal branchs vaulting pole 3 support.

Wherein, the upper and lower ends of the supporting rod 3 are vertically compressed by the supporting rings 2 at the upper and lower surfaces, and the upper and lower ends of the supporting rod 3 are respectively welded on the supporting rings 2 at the upper and lower ends. Therefore, when the support is not impacted, the support rods are used as supports, a good support effect is achieved, and the overall support strength is guaranteed.

In this embodiment, as shown in fig. 3, each of the support rods 3 includes a middle rod 303 and two connecting sections 302, the middle rod 303 is disposed between the two connecting sections 302, a cavity is respectively disposed at an upper end and a lower end of the middle rod 303, a spring 301 is welded and fixed in the cavity, one end of the spring 301 extends out of an outer side surface of the cavity, the extending end of the spring is welded and fixed with an end surface of the connecting section 302, and the connecting section 302 compresses the spring 301 on an inner wall of the cavity. When the vehicle striking, can strike on the intermediate lever of bracing piece, make intermediate lever and the linkage segment of last lower extreme take place the displacement, make intermediate lever and linkage segment separation, the vehicle can be fine like this cushions through the intermediate lever, because through spring elastic connection between intermediate lever and the linkage segment of last lower extreme, utilize the spring as elastic buffer after being strikeed, the vehicle can not strike on the pier like this, only can offset by the intermediate lever of displacement, because the intermediate lever displacement, also can reduce the impaired degree of intermediate lever equally, reduce economic loss.

Because the pier is bulky, the vehicle is after striking on the intermediate lever, the intermediate lever displacement, and the locomotive of vehicle can partly block in the buffer chamber, and the intermediate lever of vehicle both sides can block the locomotive and hit partial both sides into this moment, prevents the vehicle displacement, reduces the secondary traffic accident that the vehicle bounce-back appears.

Wherein, the structure of support ring 2 and support column 5 formula as an organic whole, it is whole to be "worker" font, and all adopts stereoplasm steel, sliding contact between assembly intracavity wall of support ring and the pier, and the support column is spliced mutually by two semicylinder structures and is formed a cylindricality structure, and the splice department welded fastening.

In this embodiment, the externally mounted of support column 5 has sound absorbing structure, and sound absorbing structure includes solid fixed ring 4 of round, and solid fixed ring 4's lateral surface is provided with the annular chamber of round, and the annular intracavity is filled and is had sound cotton 6 of inhaling, inhales the solid fixed ring 4 lateral surfaces of 6 lateral surfaces protrusions of sound cotton. Because the bridge pier is arranged under the platform bridge, the noise of the vehicle is high, the attraction structure is hidden in the bridge pier, the noise can be well reduced, other noise reduction structures are not needed to be arranged outside, the noise reduction problem can be solved, and the protruding sound absorption cotton can be used as the buffer of the vehicle.

Wherein, the outside of many spinal branchs vaulting pole 3 all is scribbled warning paint. Light irradiation in the vehicle driving process is on the bracing piece, increases warning effect through warning paint, tells the vehicle to keep away from pier one side, reduces the striking.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
