Abstract
The utility model discloses a precast box beam, which comprises an inner mold, a bottom mold, a walking beam arranged in the inner mold, a guide rail arranged in longitudinal direction below the walking beam and fixedly connected with the walking beam, and a plurality of first rollers connected with the bottom mold, wherein the guide rail can move on the first rollers. The integral formation of the template can simplify the installation and the extraction operation of the inner mold and can simplify the roller structure to achieve easy manufacture. In addition, the inner mold can be moved out of the box beam without directional hanging, thereby achieving less occupied site area, improving turnover utilization rate around the site, and improving operation efficiency.
Description
Technical field
The utility model relates to the site operation apparatus field, and especially a kind of prefabricated case that is used for the high-speed railway Line for Passenger Transportation adopts the main equipment of all-hydraulic whole deploying and retracting internal mold.
Background technology
On the high-speed railway Line for Passenger Transportation, in view of the high standard requirement of high speed traveling to the smooth-going performance of circuit, therefore most of highway section all adopts the bridge construction form to cross over, and this makes whole hole hollow prestress box-girder obtain widely applying.In prefabricated process, one of essential heavy construction equipment is exactly the supporting mould one " internal mold " that forms space in the casing.When internal mold is shifted out the fine strain of millet case, must lay guide rail in the internal mold outside, so that internal mold is hauled out, workload is just bigger like this, and length consuming time, and the occupied ground area is big, and the mobility of construction is just poor.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of high speed to carry the prefabricated fine strain of millet case of special line for passenger trains.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of prefabricated case beam, comprise internal mold, bed die, walking beam is installed in the internal mold, the below of walking beam is provided with guide rail along the longitudinal direction, this guide rail is fixedlyed connected with walking beam, connects a plurality of first rollers on the bed die, and this guide rail can move on first roller.
Further, also comprise draw-gear, this draw-gear is positioned at the internal mold outside along the longitudinal direction.
Further, the described internal mold outside also is provided with second roller along the longitudinal direction, and second roller is between draw-gear and internal mold.
Further; described internal mold also comprises backform; with the hinged side form of backform; and the load-bearing pillar that is used to support backform; this load-bearing pillar is connected with walking beam by hydraulic jack; be connected by hydraulic jack between backform and the side form, and the fluid power system that is used to drive hydraulic jack.
The beneficial effects of the utility model are because template is formed whole form, make internal mold installation, shift out operation and simplify, and wheel track is simplified the structure, be easy to make.In addition, make internal mold shift out the fine strain of millet case and can non-directional hang and draw, the turnover utilization rate around the few and place of occupied ground area is improved, and has promoted operating efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial cross section figure of Fig. 1.
Among the figure, 1, internal mold, 3, bed die, 5, walking beam, 7, guide rail, 9, first roller, 11, draw-gear, 13, second roller, 15, backform, 17, side form, 19, the load-bearing pillar, 21, fluid power system.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Prefabricated case beam as shown in Figure 1, comprise internal mold 1, bed die 3, and draw-gear 11, this draw-gear 11 is positioned at internal mold 1 outside, and draw-gear 11 is positioned on the longitudinal direction of internal mold 1, this draw-gear 11 is used for internal mold 1 is pulled out the fine strain of millet case. and internal mold 1 also is equipped with walking beam 5, the below of walking beam 5 is provided with guide rail 7 along the longitudinal direction, connects a plurality of first rollers 9 on the bed die 3, and this guide rail 7 can move on first roller 9.In addition, internal mold 1 outside also is provided with second roller 13 along the longitudinal direction, and second roller 13 is between draw-gear 11 and internal mold 1.Internal mold 1 comprises backform 15, with backform 15 hinged side forms 17, and the load-bearing pillar 19 that is used to support backform 15, this load-bearing pillar 19 is connected with walking beam 5 by hydraulic jack, be connected by hydraulic jack between backform 15 and the side form 17, and the fluid power system 21 that is used to drive hydraulic jack.
When needs use prefabricated box girder inner formwork 1, first roller 9 at first is installed on bed die 3, and second roller 13 is arranged in fine strain of millet case arranged outside, then prefabricated box girder inner formwork 1 is drawn to pouring position by draw-gear 13 along first roller 9, second roller 13, then load-bearing pillar 19 is increased to the designing requirement height, in addition side form 17 is launched, be deployed into the degree of designing requirement when side form 17 by fluid power system 21, keep this state, just can carry out the reinforced concrete box beam and make.
At last, finish when case is beam prefabricated, after concrete strength reaches demoulding strength, it is dismountable internal mold 1, at first shrink by the side form 17 of fluid power system 21 with internal mold 1, then load-bearing pillar 19 is reduced to the appropriate location, the walking beam 5 of internal mold 1 outwards moves at the traction lower edge of draw-gear 11 first roller 9, second roller 13, is hauled out until whole internal mold 1.This stripping means mechanization degree height, high efficiency.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the manual, must determine its technical scope according to the claim scope.
