Abstract
The utility model relates to a railway concrete continuous beam implemented on basis of a flat pushing method. A railway strides a newly-built railway, so that the span of a bridge structure needs to be increased, and the span of the bridge structure has a tremendous influence on stress, safety and economy of the bridge structure. A pile foundation, a bearing platform and a pier are built on the railway concrete continuous beam from bottom to top once, an upper turntable and a lower turntable are arranged between the bearing platform and the pier, and a rotating spherical hinge is arranged between the upper turntable and the lower turntable so as to carry out rotation construction; multiple rows of translation chutes, which are parallel, are arranged on a contact surface of the bearing platform and the lower turntable so as to carry out flat pushing construction; multiple rows of joist steels, which are parallel, are pre-buried on the upper surface of the bearing table, multiple rows of grooves are arranged on the positions, which are corresponding to the joist steels, in the bottom surface of the lower turntable, and the joist steels slide in the grooves to form the translation chutes; steel plates with omega-shaped cross sections are pre-buried in the full lengths of the grooves at the bottom surface of the lower turntable, and polytetrafluoroethylene plates are stuck on the bottom surfaces of the steel plates. The railway concrete continuous beam has the advantages of strong applicability, convenience for construction, small interaction effect on existing operation and better economy.
Description
Technical field
the utility model belongs to bridge construction technical field of buildings, is specifically related to a kind of railway concrete continuous beam of implementing based on flat stacking.
Background technology
Continuous reinforcement along with railway construction in China dynamics, on newly built railway, the situation of spanning existing railway occurs often, and in order not affect the safe operation of existing railway, newly built railway bridge should be as far as possible away from both wired, take rational construction method, reduce construction to both impacts of wired operation.
Conventional construction method has incremental launching method and construction by swing, and incremental launching method is applicable to the steel work that beam body is lighter, and construction by swing is generally applied to concrete beam.No matter be incremental launching method or construction by swing, its construction determines by closing on both wired bridge pier from both wired distance, want away from both wired, must increase bridge construction span, and that bridge construction is stressed, safety and economy etc. are affected by bridge construction span is very large, the span that increases bridge construction for the temporary measure of construction stage is obviously unreasonable.Therefore research is not increasing under bridge construction span prerequisite, can away from the method for both wired constructions, seem very necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of railway concrete continuous beam of implementing based on flat stacking, in the situation that not increasing bridge construction span, can, away from both wired constructions, will drop to minimum to the Influence to operation of existing railway line.
The technical scheme that the utility model adopts is:
A railway concrete continuous beam of implementing based on flat stacking, once constructs pile foundation, cushion cap and bridge pier from bottom to top, and top rotary table and lower rotary table are set between cushion cap and bridge pier, and rotation ball pivot is set between top rotary table and lower rotary table, it is characterized in that:
Described cushion cap with on the contact surface of lower rotary table, be provided with parallel several rows translation slideway.
Described cushion cap upper surface is embedded with parallel several rows i iron, and the position of the corresponding i iron in lower rotary table bottom surface is provided with several rows groove, and i iron slides and forms translation slideway in groove.
In the groove of described lower rotary table bottom surface, total length is embedded with the steel plate that cross section is " several " font, and steel plate groove bottom is covered with tetrafluoro plate.
The utlity model has following advantage:
The related using method applicability of the utility model is strong, easy construction; Bridge construction construction is little to influencing each other of both wired operations; The safety that meets existing railway operation with increase bridge construction span is compared, and translation method construction economy of the present utility model is more superior.
Accompanying drawing explanation
Fig. 1 is horizontal sliding elevational schematic view.
Fig. 2 is horizontal sliding side schematic view.
Fig. 3 is horizontal sliding floor map.
Fig. 4 is slideway schematic diagram.
In figure, 1-bridge pier, 2-top rotary table, 3-lower rotary table, 4-rotates ball pivot, 5-translation slideway, 6-cushion cap, 7-pile foundation, the interim cushion cap of 8-, 9-grouser basis, 10-tetrafluoro plate, 11-steel plate, 12-i iron.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
The railway concrete continuous beam of implementing based on flat stacking that the utility model is related, once construct pile foundation 7, cushion cap 6 and bridge pier 1 from bottom to top, top rotary table 2 and lower rotary table 3 are set between cushion cap 6 and bridge pier 1, between top rotary table 2 and lower rotary table 3, arrange and rotate ball pivot 4, carry out rotator construction.On the contact surface of cushion cap 6 and lower rotary table 3, be provided with parallel several rows translation slideway 5, carry out horizontal sliding construction.
The horizontal sliding system of translation slideway 5 is realized by following structure: cushion cap 6 upper surfaces are embedded with parallel several rows i iron 12, and the position of the corresponding i iron 12 in lower rotary table 3 bottom surfaces is provided with several rows groove, and i iron 12 slides and forms translation slideway 5 in groove.In addition, in the groove of lower rotary table 3 bottom surfaces, total length is embedded with the steel plate 11 that cross section is " several " font, and steel plate 11 groove bottom are covered with tetrafluoro plate 10, reduces slideway friction power and structure wearing and tearing, reduces energy consumption, improves horizontal sliding speed.
Specific construction step is as follows:
By following steps, realized:
Step 1: construct pile foundation 7 and cushion cap 6 from bottom to top, at the pre-buried parallel several rows i iron 12 of cushion cap 6 upper surface, i iron bottom is bolted;
Step 2: two bridge piers 1 of bridge construction that close on existing railway line, away from closing on the left line of existing railway line or right line, are parallel to existing railway line construction bridge pier 1 and beam structure;
Step 3: when bridge pier 1 and beam structure are placed in to cushion cap 6 top, top rotary table 2, lower rotary table 3 and the rotation ball pivot 4 between the two are set between cushion cap 6 and bridge pier 1; Before this, in the position of the corresponding i iron 12 in lower rotary table 3 bottom surfaces, several rows groove is set in advance, i iron 12 slides and forms translation slideway 5 in groove, and in the groove of lower rotary table 3 bottom surfaces, the pre-buried cross section of total length is the steel plate 11 of " several " font, and steel plate 11 groove bottom paste tetrafluoro plate 10;
Step 4: by steel strand and supporting hoist engine by the horizontal sliding of pier beam one to design attitude, finally carry out rotator construction, closure.
When the translation distance of pier beam one is larger, need on mobile route, extend the length of cushion cap 6, when constructing cushion cap 6, in cushion cap 6 one sides, construct interim cushion cap 8, construct in advance before this grouser basis 9 of interim cushion cap 8 belows, the same pre-buried i iron 12 of interim cushion cap 8 upper surface is listed as along connecing with the i iron of cushion cap;
After the end of job, remove grouser basis 9 and interim cushion cap 8.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
