Description

A kind of maintenance unit of bridge pad

Technical field

The present invention relates to the maintenance unit in the maintenance field, particularly a kind of bridge pad of bridge.

Background technology

In the bridge construction process, in order to reduce bump and the vibration that vehicular load causes bridge, simultaneously also in order to satisfy the needs of bridge board different directions displacement, generally at the bent cap of bridge and shelve between the bridge board on it and be provided with bearing, wherein mostly be the rubber material, aging easily, the special inflow use of bearing inferior and the appearance of jerry-built project at a low price in recent years, the replacing of bridge maintenance and bearing has market greatly.Traditional method for maintaining is, sets up support from the road under bridge face, will change, keep in repair after the bridge board jack-up, therefore, needs road closure, envelope bridge when maintenance, influence traffic, and this method can't be used for the bridge of bridge pier post at the sea, river.For this reason, it is a kind of with the maintenance unit of bridge pier post as stressed bearing post that " maintenance unit of bridge pad " that my utility model patent formerly is ZL00235236.2 number provides, it includes anchor ear brake holding and following brake holding on the bridge pier post, and on, following brake holding connects by strut, form whole fixed mount, jack is set thereon, and by embracing fixedly a plate of holder, the many also whole up connecting rod groups that are the umbrella frame shape are set on junction plate again, the upper end of connecting rod group links to each other with joist under being positioned at bridge board, thereby forms the carriage of an integral body.During maintenance, only need the upwards fixed top of jack, then joist will hold up bridge board, the bearing on the promptly replaceable bent cap.This device since with the bridge pier post as stressed bearing post, thereby go for different types of rridges, and can be used to finish the large-tonnage operation, while can construct, be open to traffic, do not influence traffic.

Yet, for some small bridge, this device is too complicated, as " breaking a fly upon a wheel ".On the other hand, in the practice of construction process, we have also found the another one problem, be after bridge board is held up by joist, since joist parallel with bent cap transversely do not have spacing, thereby lateral shift can take place when being held up or putting down in bridge board, thereby accurately resetting of bridge board impacted, even it is dangerous that construction takes place.

Summary of the invention

Technical problem to be solved by this invention is to provide the more maintenance unit of the bridge pad of advantages of simple of a kind of structure at above-mentioned prior art present situation, is suitable for the bigger small bridge in gap between bent cap and the bridge board.

Another technical problem to be solved by this invention provides a kind of bridge board and is being held up or putting down the maintenance unit that the bridge pad of lateral shift takes place Shi Buhui.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: the maintenance unit of this bridge pad includes at least two Z font carriages that are arranged on the right angle bending of bent cap side, is provided with a jack on the lower flap portion of each carriage at least.

In order to utilize the jack stand bridge board and don't it to be caused damage, can directly be provided with base plate at the jack top, also can on the jack of relative bent cap homonymy, be provided with joist.

Because the bearing that is arranged between bridge board and the bent cap is not a whole piece, but the compartment of terrain is provided with, therefore, when construction, only need to select the interstitial site of two adjacent bearings, between the last flap insertion bridge board and bent cap with Z font carriage, and its riser is close to the sidewall of bent cap, so Z font carriage promptly is in firm state, thereby provide enough supportings for the jack on it, joist.

In order to make described Z font carriage have better weight capacity, its riser has one to lower extension, and is welded with triangular support plate between itself and lower flap portion.

In order to prevent that joist from outwards overturning, simultaneously also in order to prevent that bridge board is after being held up by joist, the lateral shift parallel with bent cap can not take place, described Z font carriage has four at least, is positioned at the both sides of bent cap in twos, described joist also correspondingly has two, lay respectively at the both sides of bent cap, these two joists are all long than bent cap, and two ends stretch out respectively and surpass the end of bent cap, and, be fixed with a spacing beam of pressing close to the bent cap end face between the end of these two joist homonymies.Like this when joist holds up or puts down bridge board, because that the spacing beam that is positioned at the bent cap two ends under the restriction of bent cap end, can only take place with joist is up and down, thereby stopped bridge board fully the possible of lateral shift taken place when being held up or putting down.

The Z font carriage that is arranged on the bent cap both sides setting that can interlace at interval simply, this moment, the last flap of Z font carriage can be wide with bent cap, so that from the maximum supporting of bent cap acquisition; But better, the described Z font carriage of bent cap both sides that is arranged on is for being oppositely arranged in the same bearing gap, at this moment, the last flap of Z font carriage can have a C font breach, and relative last flap forms a S shape snap close in relative indentation, there interlocking, such two relative Z font carriages not only can be used as an integral body and obtain maximum supportings from bent cap, but also become more firm because of having so mutual interlock assembly; Do not turn up in order to make Z font carriage be adjacent to bent cap better after stressed, can make that flap has the part that extends downward under the bent cap under two relative Z font carriages of bent cap both sides, office, and both link to each other with gripper shoe with bolts between this one.

At the abutment place, because its upper surface width is limited, and Z font carriage can only be arranged on the one side, for strengthening connecting, then can have installing hole in advance on its riser of Z font carriage, fixes with the facade of planting bolt and abutment when construction.In order to prevent that the bridge board on the abutment from lateral shift taking place when being held up or putting down, can be fixed with one perpendicular and press close to the horizontal limited block of abutment side end face in the described joist end that is arranged on the Z of the abutment place font carriage with joist.

Compared with prior art, the present invention changes original bridge pier post supporting by Z font carriage and is the bent cap supporting, and it is much simple that structure is obviously wanted, and it is also more convenient to construct, and is suitable for the bigger middle-size and small-size bridge in gap between those bridge boards and the bent cap.
