Description
Technical field
The present invention relates to high-speed railway construction template, be specially a kind of adjustable ballastless track self-compacting concrete perfusion gang form.
Background technology
Plate-type slag-free orbit is one of important form of high-speed railway slag-free rail, and China has built many high-speed railways (Line for Passenger Transportation).Recent China independent research CRTS III plate-type ballastless track structure, the good self-compacting concrete of mobility is adopted to substitute original asphalt cement mortar as the packed layer between track plates and base, improve the durability of track structure, reduce the cost of track simultaneously.
But in self-compacting concrete casting process, there is following weak point in existing template:
1, track slab pavement precision is affected: the longitudinal laying design spacing of plate-type slag-free orbit plate only 70mm, sometimes even 50mm is only had, the support between cross form cannot be carried out, the method squeezing into timber wedge reinforcing can only be taked at present, but the impact force be subject to very easily causes track slab pavement deteriorated accuracy;
2, the easy spillage of template and base joint portion: in order to ensure draining, base is designed with the weathering of 6% to both sides, knick point design 50mm place within self-compacting concrete, at present, weathering is by artificial closing slope, and error is comparatively large, cannot ensure that the domatic gradient one is made peace slope leveling.When adopting channel-section steel shape vertical framework, because vertical framework thickness is thicker, the sight line of impact filling spillage point, under huge injection pressure effect, template and base very easily produce spillage, and then affect the pouring quality of self-compacting concrete;
3, track plates corner spillage is serious: the bight of track plates is arcuate structure, at present, by the impact of the base drain gradient during angle position formwork, longitudinally there is larger gap (design reasons is caused) with cross form joint portion, add the error that upper bed-plate construction exists artificial closing slope, cause the gradient suddenly big or suddenly small, extremely difficult during construction, often because of rotation angle position spillage, cause self-compacting concrete not full, the direct durability affecting track structure, intractability is greatly, costly afterwards;
4, self-compacting concrete waste is serious: during perfusion self-compacting concrete, need the air got rid of in track plates corner at the bottom of plate and between base, at present, exhaust (plasma discharge mouth) is provided with in track plates corner, while exhaust, discharge a large amount of self-compacting concretes and cement grout, not only cause the waste of self-compacting concrete, cause the severe contamination of base simultaneously.
Summary of the invention
The present invention to exist when existing template builds self-compacting concrete that precision is poor, pouring quality is poor, waste is serious to solve and clears up problem consuming time, provides a kind of adjustable ballastless track self-compacting concrete perfusion gang form.
The present invention adopts following technical scheme to realize: adjustable ballastless track self-compacting concrete perfusion gang form, comprises vertical framework, cross form, splices and the corner formwork coordinated with track plates bight with vertical framework and cross form, vertical framework comprises stencil body, the outer face of stencil body is provided with horizontal stiffener and waling, and the two ends, left and right of stencil body outer face be fixed with stretch out its end withhold plate, stencil body outer face be fixed with perpendicular and be positioned at the connection end plate withheld inside plate, connecting on end plate and have bolt connecting hole, cross form comprises stencil body I, the two ends, left and right of stencil body I outer face are fixed with the button pressure plates I of stretching out its end, stencil body I outer face is fixed with connection end plate I that is perpendicular and that be positioned at inside button pressure plates I, connect on end plate I and have bolt connecting hole I, stencil body I outer face is fixed with the platen bearing being positioned at and connecting the distribution of inside end plate I and left and right, platen bearing is provided with axis of rotation, axis of rotation is fixed with cam-like platen, corner formwork comprises arcuation stencil body and vertical framework body, the lower end of arcuation stencil body is provided with the arc structure coordinated with the base gradient, the upper end of arcuation stencil body is provided with the arc structure coordinated with the base gradient ± 1mm, the connection baffle plate distributed up and down is fixed with between arcuation stencil body and vertical framework body, the exhaust opening that two connection baffle plates surround is outside equipped with and is communicated with and the supercharging bend pipe of upwards bending with it, the horizontal base end face of supercharging bend pipe has plasma discharge mouth, plate is provided with between arcuation stencil body and vertical framework body, connect on baffle plate and be screwed with the pushing tow bolt contacted with plate, arcuation stencil body external surface is fixed with connection end plate II that is perpendicular and that be bolted with bolt connecting hole I, vertical framework body outer surface is fixed with connection end plate III that is perpendicular and that be bolted with bolt connecting hole, connect end plate II and be connected the reinforcement gusset being provided with between end plate III and fixing with both.
By controlling the thickness of vertical framework, be convenient to observe the closely connected situation bottom template and between base, be convenient to adopt polyurethane to carry out shutoff to artificial closing slope without the spillage point caused that is cut, reinforcing rib ensure that the Rigidity and strength of vertical framework simultaneously, what be crisscross arranged up and down withholds the planeness that plate ensure that adjacent forms, is just being inverted use constructability simultaneously; By arranging the connection connecting end plate and be convenient between cross form, vertical framework and corner formwork, the setting of cam-like platen forces holding out against mutually of adjacent forms, and meets the spacing of different track plates; The arc structure design of the upper and lower section of arcuation stencil body adapts to the error of the artificial closing slope of base, solve the problem of rotation angle position spillage, move up after self-compacting concrete enters supercharging bend pipe simultaneously, add its injection pressure, ensure that the filling concrete in corner area is full, subsequently by inserting board, open plasma discharge mouth, unnecessary concrete recycle is recycled; Overcome and to have when existing template builds self-compacting concrete that precision is poor, pouring quality is poor, waste is serious and clear up problem consuming time.
Reasonable in design of the present invention is reliable, and the more convenient dismounting of template and scene are had bad luck, and intervisibility is good, is convenient to the spillage point that the artificial closing slope error of shutoff is formed; And adapting to the track plates transverse joint of different in width, the nothing achieving template impacts bracing reinforcement, is conducive to keeping track slab pavement precision; Both improve track plates corner concrete plumpness simultaneously, and can reclaim in time again more than concrete recycling, improve quality, cut the waste; Have light, durable, flexible and cut the waste, cost-saving advantage.
