Description

Cross-saddle single-track traffic environment protection movable formula pre-track beam forms system
Technical field
The present invention relates to cross-saddle single-track traffic pre-track beam forms system, applied to straddle-seat type single traffic rail beam Prefabrication process in.
Background technology
Track girder in cross-saddle single-track traffic is both the track of the beam body of carrying and vehicle pass-through, and track girder is in vehicle By when its top surface, totally three faces are running surface of wheeltrack for two sides, i.e., vehicle tyre load is born on these three faces.Track Three runnings surface of wheeltrack of beam are in addition to carrying, or the track that vehicle is run.Three runnings surface of wheeltrack of track girder are bent in space Face changes, and the making required precision of track girder is high.Therefore, the requirement to template system is strict.
At present, the pre-track beam forms system in cross-saddle single-track traffic mainly includes concrete foundation, left and right coagulation Native counter force wall, steel template system and track girder transportation system.Wherein, steel template system include side template, Side Template, end template, Back timber, suspender, mechanical jack;Track girder transportation system includes bottom die trolley, steel rail line.Left and right concrete counter force wall with Concrete foundation is poured as an entirety, and the beam-ends of back timber is fixed on concrete counter force wall in steel template system.Steel form system End template in system is placed in the top surface of bottom die trolley, and Side Template is placed on end template.It is mechanical very heavy in steel template system Top is arranged on concrete counter force wall, and suspender is arranged on back timber.Side template is hung under suspender, and respectively with mechanical jack Connection.Steel rail line is laid in the concrete foundation between the concrete counter force wall of left and right in track girder transportation system.Track girder Transportation system's bottom die trolley transports before beam processed framework of steel reinforcement, bearing and Side Template needed for pre-track beam by steel rail line Into the steel template system between the concrete counter force wall of left and right.Mechanical jack is adjusted, so that side template meets track girder Linear requirement.After precast beam is poured and finished, prefabricated track girder is transported.Because basis and counter force wall are concrete cast-in-situ Into, it is necessary to use substantial amounts of concrete.Meanwhile, the template system later stage can produce substantial amounts of building waste when removing, to environment Cause very big destruction.In addition, the template system can not follow circuit place to move and spelling, and casting concrete base The field operation such as plinth and concrete counter force wall will restrict the production cycle of beam making field.
Existing pre-track beam forms system, needs to use substantial amounts of concrete when determining the construction template system Pour basis and counter force wall.After the completion of whole pre-track beam making work, it need to remove used in track beam form system Volume of concrete foundation and counter force wall, and recover the work such as prepartion of land, these work can cause noise pollution and a large amount of Building waste.In addition, the work characteristics of existing track beam form system, determines making place and the rail of pre-track beam Road beam, which is installed, sets up distance location farther out, track girder needs to reconnoitre circuit on the way in advance during long distance transportation, Closing and consolidation process.It is a large amount of by expending when transporting track girder especially on the sections such as restricted bridge, tunnel and street Man power and material.Meanwhile, the beam making field area that existing track beam form system takes is big, need to take over for use larger place so as to Preserve substantial amounts of pre-track beam body.
The content of the invention
The technical problems to be solved by the invention are:The disadvantage of a large amount of concrete need to be used by solving pre-track beam forms system End, reduces the usage amount of concrete, reduces the discharge and the pollution to environment of building waste;Solve existing template system not removable The drawbacks of dynamic, track beam form system is moved with construction of line place, spelling and Reusability, reduce track girder fortune By the restrictive condition in bridge, tunnel and street etc. when defeated, shorten the transportation range of track girder, reduce cost of transportation;Shorten system Liang Chang production cycle, improves the service efficiency of track beam form system, reduces the construction of cross-saddle single-track traffic civil engineering Cost.
The technical solution adopted for the present invention to solve the technical problems is:
Cross-saddle single-track traffic environment protection movable formula pre-track beam forms system, the template system includes:Track girder is transported Defeated system and steel template system;Track girder transportation system includes bottom die trolley, steel rail line;Steel template system include side template, End template, back timber, suspender, mechanical jack;Bottom die trolley is placed on steel rail line, and end template is placed on bottom die trolley;Hang Tool is arranged on part or all of back timber;Side template is hung under suspender, and the outside of side template is connected with mechanical jack;
Cross-saddle single-track traffic environment protection movable formula pre-track beam forms system, it is characterized in that:It is except track girder is transported Outside system and steel template system, also including steel frame system;
Steel frame system includes back timber, steel strut, longeron, or back timber, steel strut, longeron, bottom girder, or back timber, steel strut, Longeron, diagonal brace, or back timber, steel strut, longeron, bottom girder, diagonal brace;
One Pin steel frames include a back timber and two steel struts, and the upper end of the two ends of back timber respectively with two steel struts is entered Row connection;Steel strut is supported in its side with diagonal brace, or is connected in its lower end with bottom girder, or its side with diagonal brace support and Its lower end is connected with bottom girder;Steel strut and diagonal brace lower end are fixed on the ground, or are fixed on bottom girder;Adjacent steel frame is adjacent It is longitudinally connected using longeron progress between bottom girder;Mechanical jack is fixed on steel strut;
Longeron includes upper longeron, intermediate longitudinal girder, lower longeron, bottom girder.
Connection between the back timber, steel strut, diagonal brace, bottom girder and longeron is connected by screw bolts, welded or pin joint.
The steel frame, diagonal brace, bottom girder and longeron use shaped steel or steel plate processing and fabricating.
The cross-saddle single-track traffic environment protection movable formula pre-track beam forms system includes N Pin steel frames, N value For 10~30;Longitudinal pitch between adjacent steel frame is 0.5~10m.
The beneficial effects of the invention are as follows:The track beam form system replaces original track beam form system using steel frame system Concrete foundation and concrete counter force wall in system, greatly reduce the consumption for building track beam form system concrete, so that Reduce the discharge and the pollution to environment of building waste.Meanwhile, realizing track beam form system can be with construction of line place Move, spelling and Reusability, pass through the restrictive condition in bridge, tunnel and street etc. when reducing track girder transport, shorten The transportation range of track girder, reduces cost of transportation;Shorten the production cycle of beam making field, improve the use effect of track beam form system Rate, reduces the construction cost of cross-saddle single-track traffic civil engineering.
