Abstract

The utility model relates to a maintenance device for a bridge supporting seat, which is especially used for carrying out exchange to a supporting seat arranged between a bridge plate and a cover beam in a highway and a city overhead and sea-crossing bridge. The device is composed of a fixing frame, a universal moving fame and a bracket; the fixing frame is formed by that an upper and a lower brakes are connected into integration through a bracing; the universal moving fame is formed by that a jack, a joist and a connecting plate are connected into integration through a connecting rod, and the universal moving fame is fixed on a fixing plate; the bracket is connected into integration with a clinch bracket. The device uses a bridge pier column as a stressed support column, and can be used to perform large-tonnage work; when the construction is carried out, the traffic can not be affected. The device can also protect a bridge face paving layer from being damaged, is suitable to be used and for the maintenance of bridge with different structures, and can be used in other maintenance operation of bridges.

Description

The maintenance unit of bridge pad

The utility model relates to a kind of maintenance unit of bridge critical piece, particularly in freeway bridge, urban viaduct, sea-crossing bridge, to being installed in the maintenance unit of the bridge pad between bridge board and the bent cap.

Along with the development of communication, each city and intercity for transport solution crowds and blocked state has been built one after another and has much been striden river, sea-crossing bridge and road bridge, viaduct, freeway bridge.As time goes on, in bridge, play anti-collision, reduce vibration and telescopic action, and the bridge pad of being made by elastomeric material is easily aging, more fragile than other parts, thereby lose its function and effect, will directly cause the bridge breakdown so for a long time, influence the driving safety of vehicle.But can not be, and stop the use of whole highway or bridge because of the damage of bearing.How to keep in repair, change for this reason bridge pad, especially stride the replacing of river, Oversea bridge bearing, very big technical barrier really.

The patent No. 89204056.4 " bridge pad is changed frame " is changed the device of bearing though a kind of bridge that is used to keep in repair also is provided, and it adopts and place jack on crossbeam, with jack Liang Tiding is got on, thereby changes bearing.But the two ends of crossbeam are to be placed on the hanging basket, and hanging basket is again the two ends that are suspended on crossbeam, is some suspended structures entirely, do not have the fixing strong point, in case the operation unbalance stress, hanging basket will take place by the carrying out of bias effect construction.On this crossbeam, construct simultaneously, have many unsafe factors.This device can't guarantee that also the stressed energy of both sides hanging basket institute is identical in concrete operations on the other hand, therefore can not finish the large-tonnage operation and protect bridge deck pavement not impaired.And the position that the bent cap two ends of most bridge construction all do not hang hanging basket.

The purpose of this utility model is to provide a kind of maintenance unit of bridge pad, and this device can carry out the replacing of bearing safely, effectively, and can protect bridge deck pavement to avoid destroying; Can construct on one side, Yi Bian be open to traffic; Can be fit to use, the maintenance of various different bridges, and safe and reliable.

The utility model is achieved in that the maintenance unit of bridge pad is for connecting into whole fixed mount by upper and lower brake holding by strut, through jack with connect into integral body, be fixed on and constitute omnipotent adjustable shelf on the fixed head by connecting rod by joist, junction plate, again with embrace holder and connect into whole carriage and form.

Fig. 1. structural representation of the present utility model;

Fig. 2. the right view of Fig. 1;

Fig. 3. the A-A view of Fig. 1;

Fig. 4. the B-B view of Fig. 2;

Fig. 5. the C-C view of Fig. 2.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Brake holding sheet (15), (18) are that the steel plate of Ω shape is made by the cross section, inner surface is close to rubber pad (16) respectively, and sticks with glue agent through vulcanizing treatment with strengthening last brake holding (4) and the following brake holding (2) that screw (17) connects into itself and brake holding sheet (15), brake holding sheet (18) integral body.

Junction plate (8) is made by the thick rectangular plate of last regular through hole, and its thickness matches with joist (9).

Two brake holding sheets (15) connect into whole embracing with bolt, nut and hold in the palm (6).

Brake holding on two (4), twice brake holdings (2) connect into whole fixed mount with 4 struts (3) and bolt, nut.

The two sides clamping of junction plate (8), joist (9), and fix two direct-connected extension bars (11), two oblique connecting rods (12) with bolt, nut, and be weldingly fixed on the ∏ shape base plate (7), connect into omnipotent adjustable shelf, and omnipotent adjustable shelf utilizes two clamping plate on its lower end base plate, be clamped in respectively on the external surface of embracing holder (6) two ends straight line portion, pass the through hole of embracing on holder (6) and the base plate (7) with bolt, be fixedly connected into whole carriage with nut.

Corresponding bridge pier post (1) is generally 4 forward and backward and horizontal pier studs as stressed bearing post in the selection construction bridges, if bridge floor broad, long available 6 pier studs or a plurality of pier stud.

During use, 4 fixed mounts are utilized brake holding on two on it (4) and twice brake holdings (2) respectively, hug on the design attitude of 4 pier studs (1) that are buckled in the bridge both sides, and be connected, be fixed into integral body with bolt, nut and pier stud (1); Again 4 carriages are utilized embracing on it to hold in the palm (6) respectively, embrace on the pier stud (1) of fixed mount top position with bolt, nut pine; Two or more jack (5) can be placed on each fixed mount as required, and hold up each carriage on the pier stud (1) respectively; At last on fixed mount, with the jack (5) on 4 pier studs (1), upwards hold up 4 carriages simultaneously, hold up the mat formation bridge board (13) of layer (14) of bridge two sidebands by carriage again, at this moment immediately aging bearing to be changed under the bridge board (13), on the bent cap (10) is taken out, new bearing is put into installed, wait maintenance to finish, put down jack (5) and carriage then, make bridge board (13) return to the origin-location.

The utility model is compared with prior art: the reason pier column is as stressed support column, and fixing thereon Fixed mount carries out operation, and therefore safety, reliable can be used for finishing the large-tonnage operation. Again because of with very heavy Push up direct jack-up carriage, by carriage the bridge plate jack-up of integral body is changed then, so stressed equal Sparing to protect bridge deck pavement not impaired. Can according to the difference of the suffered gravity of bridge, select different numbers again Jack operate, and fixed mount, carrier structure are simple, easily make, and be easy to use, and on the carriage Omnipotent adjustable shelf direct-connected extension bar, tiltedly connecting rod can make the position make suitable accent according to the requirement of job site Whole, satisfy the requirement of construction. So this device can be widely used in the maintenance of different types of rridges and change bearing, The scope of application is wide.

This device all can be on one side when carriage jack-up bridge plate is changed bearing or made other maintenance activity Construction, one side are open to traffic, and do not affect driving.
