Description
Technical field
The utility model relates to a kind of track plates base limited impression die fixture, is specifically related to the fixture of limited impression template in the construction of a kind of CRTSIII type unballasted track bed plate.
Background technology
At present, in the construction of CRTSIII type non-fragment orbit seat concrete, reserved 2 100cm*70cm are wide for every block bedplate, the limited impression that 10cm is dark, after having poured into self-compacting concrete, track plates self-compacting concrete has formed entirety, is stuck on base by limited impression, preventing track plates displacement, is the design form of CRTSIII plate-type non-fragment orbit.At present in base is built, the shaping employing of limited impression be utilize the straddle support being arranged on base two side form, groove model is hung fixing, carries away after casting concrete and move to next circulation.Because bedplate designing requirement surface smoothness and absolute altitude are very accurate, if utilize walking beam out of shape, highly beneficial to the whole susceptor surface flatness of control, if but use the straddle cradle hangs female mold tool adopted at present to carry out shaping limited impression, the obstruction of straddle support cannot realize the through walking of walking beam, and straddle stent size is large, quality weight, carrying effort, installation is taken a lot of work.
Utility model content
One of the purpose of this utility model is for ensureing the through walking of walking beam at base top surface, and improve base top surface flatness, structure is simple, easy accessibility, reduces carrying weight, improves efficiency of construction.
The utility model solves the technical scheme that its technical problem adopts:
A kind of track plates base limited impression die fixture, comprise box-like female mold tool, bottom in described box-like female mold tool is provided with at least one horizontal back cord and at least one longitudinal back cord crossing with described horizontal back cord horizontal vertical, the two ends of described horizontal back cord are arranged with the adjustable screw mandrel perpendicular to horizontal back cord, and the centre of described longitudinal back cord is provided with the expansion bolt bottom perpendicular to described box-like female mold tool.
Base limited impression mould and seat concrete are fixed by adjustable screw mandrel and expansion bolt by a kind of track plates base limited impression die fixture that the utility model provides.In order to ensure the through walking of walking beam at base top surface, improving base top surface flatness, needing the absolute altitude up and down adjusting female mold tool, making it concordant with base upper top, be supported on Liang Mianshang by adjustable screw mandrel, groove grinding tool can be made to move up and down; Simultaneously in order to prevent in the process of building at seat concrete, limited impression mould floats, and longitudinal back cord of female mold tool is provided with expansion bolt, female mold tool, seat concrete and base beam face drawknot is fixed by expansion bolt.To sum up, the beneficial effects of the utility model are, the height achieving female mold tool end face flushes with base two side template apical side height, meanwhile, female mold tool height can be adjusted up and down, realize whole base top surface traveling walking beam leveling concrete, control susceptor surface flatness, and groove location accurately can be fixed according to setting-out position, this apparatus structure is light, easy accessibility, simple to operate, reduce carrying quantity, all can use at curve straightway, installation effectiveness is high, is beneficial to base appearance quality trait.
In addition, to compress according to the track plates of the utility model embodiment and anti-side shifter can also have following additional technical feature:
Preferably, described horizontal back cord and described longitudinal back cord are connected as a single entity.
Preferably, described horizontal back cord is two, and described longitudinal back cord is one.
Preferably, the upper end of described expansion bolt is provided with clamp nut.
Preferably, the head of described adjustable screw mandrel is fastened on horizontal back cord.
Preferably, the centre of described longitudinal back cord is provided with locating hole, and described expansion bolt is fixedly connected with beam face through after locating hole.
Additional aspect of the present utility model and advantage will part provide in the following description, and part will become obvious from the following description, or be recognized by practice of the present utility model.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present utility model and advantage will become obvious and easy understand from accompanying drawing below combining to the description of embodiment, wherein:
Fig. 1 is a kind of track plates base of the present embodiment limited impression die fixture structure top view;
Fig. 2 is the structure lateral view of a kind of track plates base of the present embodiment limited impression die fixture.
Detailed description of the invention
Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
As shown in Figure 1-2, a kind of track plates base limited impression die fixture, comprises box-like female mold tool 1, adjustable screw mandrel 2 and expansion bolt 3;
Bottom in described box-like female mold tool is provided with two horizontal back cords 4 and a longitudinal back cord 10 crossing with described horizontal back cord 4 horizontal vertical, the two ends of described horizontal back cord 4 are arranged with the adjustable screw mandrel 2 perpendicular to horizontal back cord, the head of described adjustable screw mandrel 2 is fastened on horizontal back cord 4, the centre of described longitudinal back cord 10 is provided with the expansion bolt 3 bottom perpendicular to described box-like female mold tool 1, and the upper end of described expansion bolt is provided with clamp nut 11.
As a concrete example of the utility model embodiment, described horizontal back cord 4 with the cross section of described longitudinal back cord 10 is " L " type, and the two is connected as a single entity.
The centre of described longitudinal back cord 3 is provided with locating hole, and described expansion bolt 3 is fixedly connected with beam face through after locating hole.
