The template construction trolley for a steel-frame bridge crossing a business line has the advantages of convenience in construction, movement and removal, so as to be suitable for the construction in a small space, ensure the running safety of the business line and reduce the construction risk in the construction of the business line.
Description
Technical field
The utility model relates to strides business line, highway and the construction of special rigid frame bridge, especially relates to a kind of business line rigid frame bridge template construction chassis of striding.
Background technology
Traditional existing facility rigid frame bridge job practices of striding is generally full framing reservation door opening or steel pipe support construction method.Because when construction, support set up near existing facility, have a big risk, long in time limit, after construction is accomplished, support remove difficulty and the dismounting time also longer, to remove risk very high for support in some cases, even can't remove at all.Conventional construction method duration while is very long, and operating expenses and existing facility unit cooperate expense very high.Particularly stride the business line when being two-wire, construction space is littler, adopts conventional construction method can't construct at all.
Summary of the invention
The purpose of the utility model is to provide a kind of business line rigid frame bridge template construction chassis of striding, it can for stride the construction of business line rigid frame bridge provide set up, the job platform and the formwork bracing system of dismounting, conveniently moving, and be fit to little job space.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The described business line rigid frame bridge template construction chassis of striding of the utility model, it comprises the chassis framework that is combined by a plurality of gantry unit, the bottom of said gantry unit is connected with the bottom girder that has road wheel mutually; The top of said gantry unit is disposed with a plurality of crossbeams, and said crossbeam top is equipped with the top board steel form; Be connected mutually through bolt between said crossbeam and the gantry unit; The chamfering steel form that is positioned at chassis framework upper both sides is connected with the abutment wall punching block mutually; Below said bottom girder, be provided with the support jack.
Be provided with diagonal brace between said crossbeam and the gantry unit.
The advantage of the utility model is to build, moves, removes convenient, is fit to little job space construction, in business line work progress, can guarantee the line traffic safety of doing business, and has reduced construction risk.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of construction chassis among Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, the described business line rigid frame bridge template construction chassis of striding of the utility model, it comprises the chassis framework that is combined by a plurality of gantry unit 1, the bottom of gantry unit 1 is connected with the bottom girder that has road wheel 23 mutually; The top of gantry unit 1 is disposed with a plurality of crossbeams 4, and crossbeam 4 tops are equipped with top board steel form 5; Be connected mutually through bolt between crossbeam 4 and the gantry unit 1; The right angle chamfering steel form 6 that is positioned at chassis framework upper both sides is connected with the abutment wall punching block mutually; Below bottom girder 3, be provided with and support jack 7; Be provided with diagonal brace 8 between crossbeam 4 and the gantry unit 1.
Be that example specifies with the new sweet industry rigid frame bridge construction in Liuzhou below:
1, chassis design: clear height is 9.95m in the rigid frame, and rail level is to designing 8.97m at the bottom of the rigid frame top board, and the existing railway bridge is limited to 6m, and the construction available height is 8.97-6=2.97m, and promptly top board bed die and support available height are 2.97m.
The scene uses dipstick metering must do business the line line-to-line apart from being 5.1m; Build basic gauge and laterally be 2.44m; The inboard horizontal range of business line center line distance rigid frame is (14-5.1)/2=4.45m; Bridge is limited to 2.44m, and every side mould and chassis support width capable of using within the walls is 4.45-2.44=2.01m, can satisfy the construction operation space requirement.
2, chassis structure: several respects such as comprehensive duration, site road, Liuzhou Area case of machines, economy are considered; Design chassis length 14m, height 9.95m (at the bottom of the road wheel to backform), span 12.7m; For ease of striding the assembly unit of business line; Be divided into 5 unit, each unit is made up of 5 shaped steel girder steels of both sides door frame (being an integral body) and leap business line, all adopts bolts to connect between each rod member of each unit.
The chamfering steel form 6 of chassis chamfered part adopts right-angle type, conveniently is connected with sidewall template; Top board steel form 5 adopts set shaped steel formwork, is convenient to recycling.
The gantry unit top chamfer outside of chassis is connected with thick screw rod with rigid frame fire bridge body inner side template; Inner side template is separated with concrete after guaranteeing the dismounting of wall body side form; Reduce the friction of inner side template and concrete wall body, help the walking of chassis, be convenient to the adjusting of wall body template simultaneously; And pass through the horizontal shear that screw rod is offset rigid frame when the rigid frame bridge concrete roof is built, shearing is reached build the concrete wall body that finishes.
3, chassis lifting: be installation and the dismounting that makes things convenient for chassis, chassis is made up of with bottom girder 35 independent gantry unit 1.When setting up, adopt the 180t crane to carry out bottom girder 3 hoisted in position and fixing earlier, divide the lifting door frame then 5 times; During dismounting, program with set up opposite.Installation, dismounting time weak point, main points are few, lack than conventional construction method and will put 117 times.
For ease of the lifting and the dismounting of chassis, the track length overall is than the long 36m of rigid frame bridge transverse width, and each 18m of bridge both sides, this 36m track the C25 concrete foundation of the wide 1m of cast, thick 0.5m down get final product.When chassis rises, need 14 20t jack 7 to raise 0.12m simultaneously and reach design elevation at the bottom of the top board, more adjustable chamfering template 6 is transferred to design attitude, for top board rigid frame and concrete construction provide job platform.When chassis descended, 14 20t jack 7 capable of using manually chassis and the whole whereabouts 0.12m of template system, dropped on road wheel 2 on the walking track simultaneously, promptly extensible chassis, construct second and third, chassis is removed in reach behind four, five, the six joint rigid frames.During the chassis slippage, in order better to control chassis lateral sliding and chassis translational speed, at the chassis front end 2 20t Chain block jacks are set, artificial traction is moved.
