Description

A kind of combined bridge designs a model

Technical field

The utility model relates to bridge technology field, specifically a kind of combined bridge designs a model.

Background technique

Bridge is to be built in a kind of building that river or mountain depression are convenient for the people for being separated by two places current, currently, existing Bridge is most of be all using existing topography-geomorphology, it is fixed and not reproducible be built in some specific river or mountain In low-lying area.In the prior art, number of patent application is a kind of modular bridge structure of CN201721408166.2 comprising bridge, The bottom end of the bridge is equipped with bridge pier, and spring block is mounted at the medial center of the side plate, and the bottom of the side plate is left Right two sides are mounted on bull stick, and the outer wall of the bull stick is socketed with round wheel.The modular bridge structure, when need to bridge pier into When row protection, by the cooperation of side plate and the first spring, bridge is supported by bridge pier, and the bottom of side plate is driven by bull stick justifies Wheel is rotated, and in side plate slid inward, circle wheel can make the sliding of side plate more smooth, and the outside of side plate is carried out by anticollision glue Protection can carry out buffering by the first spring to shock and reduce impact damage, can be protected to bridge pier by the device, It prevents vehicle collision to bridge pier, avoids bridge pier and collapse and generate danger.

But there is also defects when in use for above scheme:

Above scheme protects bridge pier outer wall by the first spring and anticollision glue, but works as the impact force of vehicle collision Bigger, the rebound dynamics of the first spring and anticollision glue just opposite increase is spent, so that the destruction dynamics to vehicle is formed, thus cannot Enough damages reduced while protecting bridge pier to vehicle, while usually lacking the knot protected for guardrail in the prior art Structure, therefore also improvement is needed to handle.

Utility model content

In order to make up the above deficiency, the utility model provides a kind of combined bridge and designs a model, to solve above-mentioned back The problems in scape technology.

The technical solution of the utility model is: a kind of combined bridge designs a model, including bridge plate, the bridge plate bottom End face is fixedly connected with the bridge pier that several cross sections are round setting, and the bridge pier external wall beneath is bonded by mixed mud in pairs There is doughnut-shaped steel plate, and shaft has been mounted equidistant by bearing in two doughnut-shaped steel plate opposite sides, and the shaft outer wall welds It is fixed with the rotating cylinder that bottom is open type setting, the anticollision glue-line for being tightly attached to shaft outer wall is filled with inside the rotating cylinder, it is described Rotating cylinder outer wall also passes through strong adhesive and is stained with yielding rubber cushion, is fixedly installed with above the bridge pier and is connected to bridge plate The reinforcement block of bottom face, the bridge plate top left and right sides is equidistant to be bonded with shoulder guard, and left and right institute by mixed mud The mounting groove that shoulder guard opposite side offers rectangle setting is stated, and the mounting groove inner wall slidably connects Crashworthy plate, it is described Bottom is equidistantly welded with spring in Crashworthy plate inner wall and mounting groove, and the Crashworthy plate front side wall is stained with poly- by strong adhesive Urethane rubber mount.

This setting damping protection performance is more excellent:

1. the protection of bridge pier: bridge pier outer wall bottom is bonded with doughnut-shaped steel plate, and two ring steels by mixed mud up and down Shaft is equidistantly connected with by bearing-transmission between plate, shaft outer wall is fixedly installed rotating cylinder, and rotating cylinder inside and outside wall is respectively arranged with Energy is arranged by the transmission of shaft and doughnut-shaped steel plate when vehicle collides bridge pier in anticollision glue-line and buffering rubber mount Enough impact forces for dispersing and shifting vehicle to bridge pier, while also helping and vehicle is protected, in addition, by anticollision glue-line and The cooperation of yielding rubber cushion can not only protect safeguard structure, additionally it is possible to while two-way prevention is carried out to bridge pier and vehicle；

2. the protection of shoulder guard: shoulder guard opposite side offers mounting groove, and mounting groove is interior by sliding rail and sliding block Cooperation slidably connect Crashworthy plate, Crashworthy plate inner and outer wall is respectively arranged with spring and polyurethane rubber cushion, works as protection When steel plate is accidentally impacted, preferable protection effect can be played by spring and polyurethane rubber cushion, thus to protection Steel plate carries out effective protection.

Preferably, the cylinder bottom is equipped with the end cap of hollow setting by fixing bolt, and the end cap inner wall with Shaft outer wall is interspersed setting.

This setting will be opened and closed by the setting of end cap inside rotating cylinder, consequently facilitating by internal anticollision glue-line into Row replacement.

Preferably, the yielding rubber cushion of the two neighboring rotating cylinder outer wall contacts setting, and the adjacent shoulder guard Between be weldingly connected.

There are gaps between this adjacent rotating cylinder of setting, so that the yielding rubber cushion of mutually rotating cylinder outer wall will not generate Friction, and then conveniently preferably rotated.

Preferably, sliding block has been arranged in pairs at left and right sides of the Crashworthy plate, and at left and right sides of the mounting groove inner wall Offer the sliding rail to match with sliding block.

This setting is convenient for by the mutual cooperation of sliding block and sliding rail so that Crashworthy plate is moved forward and backward in mounting groove.

Preferably, the bridge plate pours fixation, and the bridge by the floorings reinforcing bar and floorings that are staggered in pairs The bottommost of beam slab is floorings reinforcing bar, and the topmost of the bridge plate is floorings.

This setting can increase the support strength of bridge plate by the floorings reinforcing bar and floorings that are staggered.
