Abstract
The utility model provides a railway line novel pre-stressed sleeper produced constant slope groove rail ditch die. The technique solutions are that: a rail ditch die combines a rail groove block and a rail fluted sheet, a mold releasing angle is arranged between the rail groove block and the rail fluted sheet, connection bolts at the ends thereof are connected with the rail groove block by a die steel bottom plate; or a rail ditch die combining a rubber rail groove block and the rail fluted sheet is adopted, two connection bolts at each end thereof are connected with the rubber rail groove block by a die steel bottom plate. The utility model effectively solves the technique problem of difficult mold releasing, after the testing, the sleeper bumping shoulder will not crack by pushing and is easy to shed, and the mold releasing rate is up to 100 per cent.
Description
Technical field
The utility model belongs to the production mould of rail track novel prefabricated concrete sleeper, a kind of specifically straight sloping groove rail supporting groove mould, and suitable production has the straight sloping groove III type pillow of shoulder block or the demoulding of II pillow to use.
Background technology
According to the knowledge of the applicant: after adopting straight sloping groove-shaped shoulder block, changed the stressing conditions of shoulder block, theory and practice shows: shoulder block is under the synergy of vertical force and cross force, and stress is little everywhere, and stress is concentrated not obvious, stressed comparatively reasonable.Enough spaces are arranged between groove place and the screw spike, be convenient to the layout of spiral reinforcement, the railway spike surrounding concrete does not have excessive stresses.Its shortcoming is sleeper specification requirement height on making, and is not easy the demoulding.Be that original its shoulder block gradient of shoulder block sleeper is arranged is 120 °, the process of producing product product stripping is more or less freely, and the novel prefabricated concrete sleeper is because its rail support groove is straight sloping groove form, the shoulder block gradient is 90 °, on technology as adopt the integral rails frid, after then prestressing force is put, sleeper produces contraction distortion, make the bigger compression of generation between sleeper shoulder block and the rail frid, causing the shoulder block of novel prefabricated concrete sleeper easily to be pushed splits, because between shoulder block and the rail frid bigger compression is arranged, form bigger frictional resistance when making the sleeper demoulding between shoulder block and the rail frid on the other hand, cause to only depend on the sleeper self gravitation from model, not take off.
The utility model content
The purpose of this utility model is to solve the technical barrier of straight sloping groove concrete sleeper shoulder block demoulding difficulty, and these characteristics according to straight sloping groove concrete sleeper shoulder block design and produce this rail supporting groove mould.
Technical solution of the present utility model is: adopt rail geosynclinal block and rail frid combination rail supporting groove mould, be provided with the demoulding angle of α≤84 ° between rail geosynclinal block and the rail frid, the attachment bolt at two ends passes through the punching block base plate and connects with the rail geosynclinal block.Or adopting rubber rail geosynclinal block and rail frid combination rail supporting groove mould, two attachment bolts of each of two ends connect with rubber rail geosynclinal block by the punching block base plate.
The beneficial effects of the utility model are: because of having certain demoulding angle between rail geosynclinal block and the rail frid, after putting, sleeper produces and shrinks, rail geosynclinal block and sleeper shoulder block produce slippage along demoulding angle direction that is provided with and rail frid together, avoid sleeper shoulder block and rail frid to put an after-contraction and form compression because of sleeper, guaranteeing that the sleeper shoulder block can not be pushed splits, because sleeper shoulder block and rail frid do not have compression, sleeper shoulder block and rail frid just can not produce ejection resistance, will deviate from model by the sleeper own wt.In like manner, adopt rubber rail geosynclinal block and rail frid to be combined into rail supporting groove mould, because rubber has bigger deformation performance, after putting, sleeper produces and shrinks, and rubber rail geosynclinal block then is compressed, reduce sleeper shoulder block and rail frid greatly and form compression because of putting an after-contraction, simultaneously the sleeper shoulder block also reduces greatly with the demoulding frictional force of rail frid, thereby the sleeper shoulder block can not be pushed and splits, and sleeper leans on the own wt also can off-type.On probation through testing, not only the sleeper shoulder block can not be pushed and split and the demoulding easily, and demolding rate reaches 100%.

Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1: the straight sloping groove rail supporting groove mould of prestressed reinforced concrete tie described in the utility model, the one technical solution is to adopt rail geosynclinal block 3 and rail frid 2 combination rail supporting groove moulds, be provided with the demoulding angle of α≤84 ° between rail geosynclinal block 3 and the rail frid 2, the attachment bolt 4 at two ends connects with rail geosynclinal block 3 by punching block base plate 1.
With reference to Fig. 2: its another technical solution is to adopt rubber rail geosynclinal block 3 ' and rail frid 2 ' combination rail supporting groove mould, and two attachment bolts of each of two ends 4 ' connect with rubber rail geosynclinal block 3 ' by punching block base plate 1 '.
