Description
Technical field
The utility model belongs to technical field of bridge construction, relates to a kind of high-speed railway 900t case beam mobile formwork moulding girder, has optimized the mechanical property of outboard template and girder, need not the secondary assembling.
Background technology
Mobile formwork can be divided into two kinds of upstriker and downstrikers according to the position of running mechanism.The upstroke movable framework running mechanism is more than the case beam, agent structure is more than bridge pier, main beam structure is bearing on Dun Ding and the in type beam body, template system is suspended on moulding main beam structure below by outrigger, arm and suspension rod, utilize the camber of rod-adjurstable adjusting template, by the linear elevation at the bottom of the designing requirement adjustment beam; The downlink movable mould frame running mechanism is below the case beam, and on the support on bridge pier side, template system was connected with the moulding main beam structure by support system before and after main beam structure was supported on.Adopt mobile formwork Cast-in-situ Beam technological principle for finishing first the assembly unit of mould bases support system, carry out again exterior sheathing and support system and install, carry out subsequently that the case beam is low, the both sides reinforcing bar binding, carry out again inner formword and support system and install, after fixing of the forming frame is complete, carry out case back section reinforcing bar binding, cast-in-place concrete carries out artificial maintenance subsequently, when the case beam reaches 75% design strength, carry out form removal, mobile formwork enters next hole beam construction.When current high-speed railway 900t case beam adopts Construction Through Form on Traveler, after erection of main beam is finished, can carry out the outboard template assembly unit, consumption power is time-consuming, has greatly limited the efficiency of construction of mobile formwork.
Summary of the invention
In order to overcome defects, the utility model purpose is to provide a kind of mobile formwork moulding girder, the cast-in-place construction that is used for high-speed railway 900t case beam mobile formwork realizes that outboard template and girder dispatch from the factory according to the moulding of beam shape size, need not on-the-spot separately assembly unit.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of mobile formwork moulding girder, it comprises outboard template, case beam and whorl brace rod, about mobile formwork moulding girder divides two, every outboard template comprises web and frange plate, web and frange plate are flexibly connected, be connected with outboard template by forward and backward two group of four double thread connecting rod on the every case beam, every group of whorl brace rod comprises two frange plate screw rods, two web screw rods, two case back section screw rods, two inboard screw rods of case beam and four threaded sleeves, and there is built-in walking rails in case back section.
Described outboard template vertically is divided into five according to 32m beam body length, two block length 4.5m, 7.5 meters of two block lengths and a block length 8m.
Described case beam is divided into five, four block length 7.5m and a block length 8m.
One end of described frange plate screw rod, two web screw rods, two case back section screw rods, two inboard screw rods of case beam is connected with the difference threaded sleeve, and the other end is welded and fixed with frange plate bottom, web outside, case back section, case beam inboard respectively.
The beneficial effects of the utility model:
The utility model discloses a kind of mobile formwork moulding girder, optimize the structural mechanical property of outboard template and girder, can realize that outboard template and girder dispatch from the factory according to the moulding of beam shape size, need not the respectively independent assembly unit of on-the-spot girder and outboard template.Comprise outboard template, case beam and whorl brace rod, outboard template comprises web and frange plate, described web and described frange plate are flexibly connected, described whorl brace rod comprises screw rod and threaded sleeve, the described threaded sleeve that turns clockwise, the screw rod at described sleeve pipe two ends along the threaded sleeve internal thread simultaneously upwards the described frange plate of jacking until expose described built-in walking rails.This moulding girder can realize that high-speed railway mobile formwork girder and outboard template moulding dispatch from the factory, and need not on-the-spot respectively independent assembly unit, and the built-in walking rails in moulding girder top shortens construction period for prefabricated case beam reinforcing bar lifting mould-entering device provides walking rails.

The specific embodiment
Be described in detail below in conjunction with accompanying drawing 1,2,3 pairs of the utility model:
A kind of mobile formwork moulding girder comprises outboard template 1, case beam 2 and whorl brace rod 3.Before according to construction direction being, about mobile formwork moulding girder divides two, described outboard template 1 vertically is divided into five according to 32m beam body length, two block length 4.5m, 7.5 meters of two block lengths and a block length 8m, every outboard template 1 comprises web 4 and frange plate 5, web 4 is flexibly connected with frange plate 5, described case beam 2 is divided into five, four block length 7.5m and a block length 8m, before passing through on the every case beam 2, rear two group of four double thread connecting rod 3 is connected with outboard template 1, every group of whorl brace rod 3 comprises two frange plate screw rods 6, two web screw rods 7, two case back section screw rods 8, two inboard screw rods 9 of case beam and four threaded sleeves 10, frange plate screw rod 6, two web screw rods 7, two case back section screw rods 8, inboard screw rod 9 one ends of two case beams are connected with threaded sleeve 10, the other end respectively with frange plate 5 bottoms, web 4 outsides, case beam 2 tops, case beam 2 inboards are welded and fixed; There is built-in walking rails 11 in case back section.
When the hoisting prefabricated case beam steel of mobile formwork enters mould and need to use built-in walking rails, opening web 4 is flexibly connected with frange plate 5 places, turn clockwise threaded sleeve 10 on frange plate screw rod 6 and the case back section screw rod 8, by frange plate screw rod 6 and case back section screw rod 8 along with threaded sleeve 10 simultaneously jacking frange plates 5 until expose built-in walking rails 11.
