Description
Technical field
The utility model relates to high-speed railway track plate mould, is specifically related to a kind of high ferro pre-tensioned prestressing track slab steel mould.
Background technology
At present, the prestressed, reinforced stretch-draw of high-speed railway pre-tensioned prestressed concrete track plates is completed by the stretching bed coordinated with railway plate die, and huge pulling force, to intensity, the rigidity condition requirement harshness of stretching bed, causes stretching bed cost very high.If railway plate die self can be utilized to realize the stretch-draw of deformed bar, avoid using stretching bed, greatly will reduce the production cost of pre-tensioned prestressing track plates.Existing track plates mould can not meet the requirement self realizing deformed bar stretch-draw.
Summary of the invention
The purpose of this utility model is that providing a kind of can meet the high ferro pre-tensioned prestressing track slab steel mould self realizing deformed bar stretch-draw requirement.
The technical scheme realizing the utility model object is: a kind of high ferro pre-tensioned prestressing track slab steel mould, and comprise bed die and the side, the end mould that are arranged on this bed die top periphery, described side, end mould are equipped with deformed bar stretch-draw rod; Described side, end mould are provided with the rib post of rectangular cross section, this rib post erect put run through described side, end mould; Described bed die is provided with horizontal load cover, the two ends of this load cover are given prominence to by the two ends of described bed die, adjusting sleeve is connected by threaded engagement at the jag of load cover, the end face outside of this adjusting sleeve coordinates with the medial surface of described rib post, prestressed steel bar runs through described load cover, adjusting sleeve and rib post, the two ends assembly prestress rod iron nut respectively of described prestressed steel bar, between prestressed steel bar nut and described rib post, be provided with backing plate, this backing plate is provided with the rod iron caulking groove coordinated with prestressed steel bar.
The circular hole combination that the elongated hole that the rod iron caulking groove that described backing plate is arranged can enable described prestressed steel bar embed by a width and a diameter make described prestressed steel bar nut pass through is formed.
After this high ferro pre-tensioned prestressing track slab steel mould combination forming, by external force stretch-draw prestressing force rod iron, stretching force is delivered on rib post by prestressed steel bar nut, and rib post plays the effect of load lever.Like this when prestressed reinforcement of tensioning, rely on the rigidity of rib post, the pulling force of prestressed steel bar pre-applied and the leverage of rib post, avoid side, end moding shape, ensure side, the physical dimension of holding mould and tolerance, thus ensure the product quality of pre-tensioned prestressed concrete track plates.
The utility model does not need configuration stretching bed to get final product production high ferro pre-tensioned prestressed concrete track plates, thus greatly reduces the production cost of high ferro pre-tensioned prestressed concrete track plates.
Accompanying drawing explanation
Fig. 1 is the structural representation of this high ferro pre-tensioned prestressing track slab steel mould;
Fig. 2 is that the A of Fig. 1 is to partial view.
Detailed description of the invention
In conjunction with the accompanying drawings and embodiments detailed description of the invention of the present utility model is described.
As Fig. 1, this high ferro pre-tensioned prestressing track slab steel mould, comprise rectangular bed die 4, side, end mould 1 is provided with at the top periphery of this bed die 4, two side forms of side, end mould 1 and two ends mould are oppositely arranged on the top of bed die 4 between two, and the lower inside surface of its side, end mould 1 and the side on bed die 4 top, end face fit tightly and be bolted fixing.Side, end mould 1 and bed die 4 form the shaping mold cavity of track slab steel mould.On described side, end mould 1, level installs deformed bar stretch-draw rod 2, and the medial extremity of deformed bar stretch-draw rod 2 is threaded deformed bar.Described side, end mould 1 are provided with the rectangular rib post 3 of cross section, this rib post 3 is perpendicular put run through described side, end mould 1 be fixed by welding in side, end mould 1, the bottom of side, end mould 1 is given prominence to below by described side, end mould 1.Described bed die 4 is provided with horizontal load cover 9, and the two ends of this load cover 9 are given prominence to by the two ends of described bed die 4, and load cover 9 is fixed by welding on bed die 4.Two jags of load cover 9 connect an adjusting sleeve 8 respectively by threaded engagement, the end face outside of this adjusting sleeve 8 coordinates with the medial surface of described rib post 3, as accompanying drawing embodiment, load cover 9 adopts point body formed structure so that processing, namely utilizes body two ends to weld an external screw thread body joint respectively and forms; Turn edge in the outboard end of adjusting sleeve 8 has, to be conducive to stable cooperation of adjusting sleeve 8 and rib post 3 medial surface, and strengthen the strength and stiffness of adjusting sleeve 8.Prestressed steel bar 5 runs through described load cover 9, adjusting sleeve 8 and rib post 3, the two ends assembly prestress rod iron nut 6 respectively of described prestressed steel bar 5, between prestressed steel bar nut 6 and the lateral surface of described rib post 3, be provided with backing plate 7, this backing plate 7 is provided with the rod iron caulking groove coordinated with prestressed steel bar 5.
As accompanying drawing 2, the elongated hole that the rod iron caulking groove that described backing plate 7 is arranged can enable described prestressed steel bar 5 embed by a width and the circular hole that a diameter makes described prestressed steel bar nut 6 pass through combine and form.The elongated hole part of backing plate 7 with prestressed steel bar 5 to backing plate time corresponding between rib post 3 and prestressed steel bar nut 6; The circular hole part of backing plate 7 and prestressed steel bar 5 are to 7 taking off from prestressed steel bar 5 time corresponding.
