Abstract
The present invention relates to a bridge support seat maintaining method and an apparatus. Particularly, the present invention exchanges a support seat which is arranged between a bridge board and a cover beam in a highway, city high erection and a sea cross bridge. The apparatus of the present invention is formed in a mode that a fixed frame which is connected into integration by an upper and a lower embracing brakes by a supporting rod, is connected with a supporting beam and a connecting board into a whole by a connecting rod through a jack to be fixed on a fixed plate so as to form a universal adjustable frame, and the universal adjustable frame and an embrace supporter are connected into an integral supporting frame. The method uses a pier column as a stress supporting column which is used for finishing large tonnage operation, a bridge can be constructed when vehicles are run, and thus, traffic can not be affected. The present invention can protect a paving layer of the bridge face against damage, is suitable for the use and maintenance of the bridges with different structures, and other maintenance operation of the bridges, and a use range is wide.
Description
The present invention relates to a kind of method for maintaining of bridge critical piece and the device that must use, particularly in freeway bridge, urban viaduct, sea-crossing bridge, to method for maintaining and the device that is installed in 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 object of the present invention is to provide a kind of method for maintaining and device of bridge pad, can carry out the replacing of bearing safely, effectively, and can protect bridge deck pavement to avoid destroying with this method; 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 present invention is achieved in that the device of bridge pad maintenance is for connecting into whole fixed mount by upper and lower brake holding by strut, through jack with by holder fine strain of millet, junction plate by straight, tiltedly connecting rod connects into integral body, is fixed on and constitutes omnipotent adjustable shelf on the base plate, and be close to by omnipotent adjustable shelf lower end base plate and embrace on the straight line portion of holder two ends, pass a through hole of embracing in the holder with bolt and be fixedly connected into whole carriage with nut and form.
The method for maintaining step:
A. the pier stud of selecting construction bridges is a bearing post,
B. fixed mount is fixed on the pier stud,
C. installation bracket on fixed mount,
D. on fixed mount, lay hydraulic jack,
E. on jack, place carriage,, operation is changed in the bridge board picking-up by carriage simultaneously firmly with each jack stand.
Fig. 1. structural representation of the present invention;
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 embodiments of the invention are further described.
Two brake holding sheets, 15 usefulness bolts, nut connect into whole embracing and hold in the palm 6, and two ends is a straight line portion 19.
Fixed mount 23 is by 4 struts 3 and bolt, nut, with brake holding on two 4, whole composition that twice brake holding 2 connects into.
Omnipotent adjustable shelf 20 is close to by the two sides of junction plate 8, joist 9 and is fixed two direct-connected extension bar 11, two oblique connecting rods 12 with bolt, nut, and junction plate 8 is weldingly fixed on the base plate 7 of ∏ shape with two clamping plate 22, connects into whole the composition.
The method for maintaining step
A. select that corresponding bridge pier post 1 is generally 4 forward and backward and horizontal pier studs as stressed bearing post in the construction bridges, if bridge floor broad, long available 6 pier studs or a plurality of pier stud.
B. 4 fixed mounts 23 are utilized brake holding 4 and twice brake holdings 2 on two on it 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.
C. 4 carriages 21 are utilized embracing on it to hold in the palm 6 respectively, embrace on the pier stud 1 of fixed mount 23 top positions with bolt, nut pine.
D. two or more jack 5 can be placed on each fixed mount 23 as required, and hold up each carriage 21 on the pier stud 1 respectively.
E. at last on fixed mount 23, assume unified command of operation, utilize the jack 5 on it, upwards hold up 4 carriages 21 simultaneously, hold up the mat formation bridge board 13 of layer 14 of bridges two sidebands by carriage 21 again, at this moment immediately aging bearing to be changed on bridge board 13 times, the bent cap 10 is taken out, new bearing put into install, finish Deng maintenance, put down jack 5 and carriage 21 then, make bridge board 13 return to the origin-location.
The present invention is compared with prior art: reason bridge pier post is as stressed bearing post, and thereon fixedly fixed mount carry out operation, therefore safety, reliable can be used for finishing the large-tonnage operation.Because of with the direct jack-up carriage of jack, by carriage the bridge board jack-up of integral body is changed then again, so the stressed bridge deck pavement of evenly can protecting is not impaired.Again can be according to the difference of the suffered gravity of bridge, select the jack of different numbers to operate, and fixed mount, carrier structure are simple, easily make, easy to use, and the direct-connected extension bar of the omnipotent adjustable shelf on the carriage, tiltedly connecting rod can make the position do suitable adjustment according to the requirement of job site, satisfies the requirement of construction.So the method can be widely used in the maintenance of different types of rridges and change bearing, the scope of application is wide.
When the method is changed bearing or made other maintenance activity at carriage jack-up bridge board,, do not influence driving while all can construct, be open to traffic.
