Technical field

The present invention relates to Technology Bridge Strengthening fields, and in particular to kerb under a kind of anticollision barrier for reinforcement bridge Device and method.

Background technique

With the increase of vehicle guaranteeding organic quantity, the requirement of traffic safety facilities is also higher and higher.On January 1st, 2018, traffic Portion has promulgated new " highway traffic safety facilities design specification ", requires to have done biggish mention to the anticollision barrier of road and bridge Height, many built bridges have been unsatisfactory for wanting for present traffic safety facilities as the way of anticollision barrier using kurbstone It asks, needs to reinforce upgrading.

It is both to have chance with since the connection of built pedestrian way of bridge kerb and floorings generallys use distributing bar connection Anticollision barrier is added on stone, but due to weak foundation, is not able to satisfy the requirement of traffic safety facilities still.

Currently used remodeling method is to remove original kurbstone, again in the cast-in-place kerb of floorings bar planting as anti- The basis of guardrail is hit, but there is also more disadvantages for this method:

(1) site concrete long construction period；

(2) construction period needs to occupy part lane width, greatly influence road traffic, makes to the trip of the people At adverse effect；

(3) bar planting range is larger on floorings, adversely affects to deck structrue itself.

Summary of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of dresses of kerb under anticollision barrier for reinforcement bridge It sets and method, solves existing strengthening reconstruction method long construction period, the big problem of traffic impact, while avoiding on floorings The problem of bar planting range is big, influences deck structrue.

To achieve the goals above, the present invention realizes by the following technical solutions:

On the one hand, the present invention provides a kind of devices of kerb under anticollision barrier for reinforcement bridge, comprising:

First stiffening plate, for being fixed on the top surface of kerb；

Side plate, for being set to side of the kerb far from lane, and side plate is connect with the first stiffening plate；

Second stiffening plate, for being fixed on floorings；And

Tilt prop, the both ends of tilt prop are separately connected side plate and the second stiffening plate.

Using above-mentioned bracing means as the basis for adding anticollision barrier, bracing means can directly be connect with floorings, It does not need to remove former kerb, can promote traffic safety facilities anti-collision level yet.Simultaneously tilt prop both ends be separately connected side plate and In second stiffening plate, whole device is made to become an entirety, automobile impact force is transferred in the second stiffening plate by tilt prop, together When be transferred to floorings, alleviate the impact force that kerb undertakes, effectively strengthen the crashworthiness of kerb.

Further, the first stiffening plate and side plate are integrally formed L-shaped.Directly it is prefabricated it is L-shaped can produce in enormous quantities, save It saves time, while reducing manual operation.

Further, the first stiffening plate is anchored at kerb top surface by bolt, and the second stiffening plate is anchored at bridge by bolt On panel.It is anchored using bolt, makes to connect stronger, it is therefore an objective to work together the two can to undertake various stress.

Further, the quantity of tilt prop is two, and two tilt props are arranged in parallel.It can using two tilt props To improve the dynamics that undertakes, anticollision grade is promoted.

On the other hand, the present invention also provides a kind of method of kerb under anticollision barrier for reinforcement bridge, including it is following Step:

Step 1: according to the size of kerb, prefabricated first stiffening plate, side plate, tilt prop and the second stiffening plate, and by first Stiffening plate is connected with side plate；

First stiffening plate: being fixed on the top surface of kerb by step 2, and side plate is made to be located at side of the kerb far from lane, will Second stiffening plate is fixed on floorings；

Step 3: the both ends of diagonal brace are separately connected the second stiffening plate and side plate.

Further, in step 1, the first stiffening plate and side plate are integrally formed L-shaped when prefabricated.Directly it is made as in advance Integrated molding can produce in enormous quantities, while guaranteeing quality, further reduce the cost, and reduce manual operation load.

Further, in step 3, the quantity of tilt prop is 2, and two tilt props are arranged in parallel.

Further, further include step 4: the bumping post of anticollision barrier is mounted in the first stiffening plate.

Beneficial effects of the present invention: the bracing means is used, does not need to remove existing kerb, reduces project cost, together When can greatly speed up construction speed, shorten construction period, and without occupying driveway, it is unfavorable that reduction goes on a journey to the people It influences, and does not need to reduce the influence to deck structrue in floorings large area bar planting；Use prefabricated board structure can be with Produce in enormous quantities, while guaranteeing quality, further reduces the cost.
