Description
Technical field
The utility model belongs to railway plate die, particularly relates to dual-direction pre-tensioning system prestressed concrete track slab mold.
Background technology
In recent years, there is the dual-direction pre-tensioning system prestressed concrete track slab of independent intellectual property right during Chinese high ferro is built
Through comprehensively being promoted, with the fast development of high ferro construction, to the quantity of the pre-tensioning system track plates of two dimension prestressing structure
Demand and quality requirement also more improve.The current existing pre-tensioning system track plates mode of production is produced using fixed station A seating,
The mode of production needs to build a large amount of ground concrete foundation structure, and mold is fixed on according to the position dimension of setting in pedestal,
A large amount of related flow chart operations one by one are needed in track plates manufacturing process, cause track plates production process technology complexity, it is raw
Produce inefficiency, the problems such as production cost significant wastage.
The prestressing force of fixed station A seating track plates working system bears the architecture basics and stretch-drawing beam steel knot that system is pedestal
Structure, mold do not stress substantially, and mold is in track plates making only necessary to will be on frame mode in strict accordance with the shape of track plates
Size is processed splicing, itself is non-stress structural framing, relatively easy in processing and making process to be easy.
According to Chinese Railway parent company print and distribute about《High-speed railway CRTSIII plate-type non-fragment orbit pre-tensioning systems are answered in advance
Power concrete railway board company standard》(TJ/GW118-2013) in requirements of the 3.3.2 to mold only to appearance and size, it is smooth,
Angularity has stringent accuracy error requirement, and requirement is not suggested that the self structure of mold.Mold production process compares
It is more traditional.
In order to adapt to the keen competition of current international high speed railway construction, research and development are more advanced, science first to open rail
Guidance tape intelligent Production Technology has become the task of top priority for embodying China's high ferro technical merit, showing national strength.Realize track
One of key problem in technology of intelligent production line manufacture of plate is mold, and mold body should be independent, packaged type
Itself beaer, to bear reaction force when two dimension prestressing tensioning so that under the stress after the completion of mold tensioning not
Deformation is generated, this just makes the structural framing of mold itself that there should be stringent force request.
The major defect performance that existing mold can not adapt to the production of double prestressed concrete track plates is following aspects：
First, mold cannot achieve railway plate die by process, station line in such a way that corresponding several base support legs are fixed on ground
The pattern of formula circulation construction operation；Second is that existing mold cannot achieve carries out two dimension prestressing by beaer of mold body
The job execution of drawing, it is necessary to fulfil assignment by extraneous load body stress；Third, existing mold cannot achieve wire type circulation operation
When precise positioning, without accurately detent mechanism；Fourth, existing mold in the stripping process of construction operation, can only use hand
The dynamic mechanical pattern opened end side mould or end side mould and integrally hung away, it is time-consuming and laborious, it cannot achieve pipeline system operation.
According to Chinese Railway parent company print and distribute about《III plate-type non-fragment orbit pretensioned prestressings of high-speed railway CRTS
The provisional technology requirement of concrete railway board》Requirements of the 3.3.1 to mold is that " should adopt in (flowing water unit method TK/GW156-2016)
With with sufficient intensity, rigidity and stability prestressing combination formula punching block or bending-resistant type monoblock type punching block, template should ensure that
The multinomial contents such as the accurate location of each portion's shape of track plates, size and built-in fitting " not only for the anti-stress of mold itself as it can be seen that carry
Gone out strict demand, what is more important this be also one of important research direction in mould structure design.
The prior art that applicant is understood includes：
Application No. is disclosing a kind of integral combined high-speed railway track plate punching block of prestressing force in 201510936956.7,
Its agent technology scheme be include a bed die, two side forms and two end moulds, along the longitudinal direction of the bed die below the bed die
Several steel pipes of fixed placement, the transverse direction below the steel pipe along the bed die have been fixedly installed several square steel A, the square steel A
Lower section is provided with several square steel B along the longitudinally fixed of the bed die.There are following technological deficiencies for the above-mentioned prior art：First, using
The stressed member of bed die, square steel A, square steel B, longitudinal steel pipe as mold, lacks stress frame as torque fulcrum, bed die as by
Power part has an impact the stability of track plates dimensions；Two are the absence of lateral steel pipe as stressed member；Third, square steel A
Fluted in bottom with square steel B and penetrate prestressed material, the two center is misaligned, cannot play a role power and reaction force from
Counterbalance effect is centrally formed torque to square steel, influences the stability of track board size after prestressed material tensioning exerts a force.
