Description
[technical field]
This utility model relates to urban track traffic and Construction Technology field, specifically a kind of railway roadbed template locator.
[background technology]
Urban track traffic is an important component part of urban public transport, and along with development and the urbanization process of national economy are accelerated, the development of track traffic is accelerated the most therewith.The track construction required precision of track traffic improves constantly with the raising of speed per hour.City rail cast-in-place solid concrete roabed formwork support arrangement many employings iron wire colligation at present or employing " step fastener " are constructed, template position cannot accurately be adjusted by these construction technologies, and work progress it is frequently necessary to carry out the methods such as percussion, often resulting in template and the deformation of formwork erection utensil or damage, railway roadbed concrete appearance size is difficult to ensure that.
[summary of the invention]
This utility model is for the problem that cannot accurately adjust template position in railway roadbed construction, uses the parts composition railway roadbed template locator such as screw mandrel, angle steel support, bolt so that it is cast-in-place solid concrete roabed template carries out more accurate location and fixes.
To achieve these goals, a kind of railway roadbed template locator of design, support including angle clip, long angle steel supports, screw mandrel, bolt, nut, described angle clip supports and is secured by bolts in two ends at the bottom of Rail respectively, the right-angle surface that long angle steel supports in level is provided with a bolt slot, bolt is in bolt slot is screwed into the bolt hole that railway roadbed template end face is preset, described angle clip supports and long angle steel supports and has screw mandrel through hole in perpendicular right-angle surface, screw mandrel is fixed in the support of long angle steel and angle clip support through nut after screw mandrel through hole, thus fix and position railway roadbed template.
The right-angle surface that described long angle steel supports in level is provided with bolt slot, and described bolt slot is parallel with the intersection of two right-angle surface, and its length is more than the spacing of the adjacent default bolt hole of railway roadbed template end face, and its width matches with bolt.
The both sides that described long angle steel supports along screw mandrel are equipped with nut.
The outside that described angle clip supports along screw mandrel is provided with nut.
Described screw mandrel is high-strength screw mandrel, and the screw mandrel hole size that the size of described screw mandrel and angle clip support and long angle steel supports matches.
This device abandoning tradition technique needs the construction methods such as percussion; not only it is beneficial to protection job site finished product and each facility; fixed effect is also advantageous over conventional construction method; template can be greatly reduced and run mould probability; and Adjustment precision is high; its Adjustment precision can reach grade, makes railway roadbed concrete appearance size reach requirement, and has the advantage such as mounting means simple and fast, cheap, length in service life.

[detailed description of the invention]
The utility model is described in further detail below in conjunction with the accompanying drawings, and the structure of this device and principle are the most clearly for the people of this specialty.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
This utility model is angle steel support, bolt etc. to be applied in combination, use bolt to be supported by angle steel and be separately fixed at the bottom of Rail and in railway roadbed template, by screw mandrel, angle steel is supported connection again, reach location and the effect of fixed form, railway roadbed template is adjusted location the most accurately, makes railway roadbed concrete appearance size meet requirement.
This device includes angle clip support, the support of long angle steel, screw mandrel, bolt, nut, sees Fig. 1 and Fig. 2, and angle clip supports and is secured by bolts in two ends at the bottom of Rail respectively.The outside that angle clip supports along screw mandrel is provided with nut.
The right-angle surface that long angle steel supports in level is provided with a bolt slot, bolt slot is parallel with the intersection of two right-angle surface, its length is more than the spacing of the adjacent default bolt hole of railway roadbed template end face, its width matches with bolt, should just meet bolt can slide along bolt slot, making vertical angle bracing members direction should not have displacement, bolt is in bolt slot is screwed into the bolt hole that railway roadbed template end face is preset.The both sides that long angle steel supports along screw mandrel are equipped with nut.
Angle clip supports and long angle steel supports and has screw mandrel through hole in perpendicular right-angle surface, screw mandrel is fixed in the support of long angle steel and angle clip support through nut after screw mandrel through hole, screw mandrel is high-strength screw mandrel, bolt, nut should support supporting with screw mandrel and angle steel, and the perforate that angle steel supports should meet screw mandrel and just pass freely through.
Seeing Fig. 3 and Fig. 4, the concrete installation method of this device is:
1, after orbit adjusting puts in place, first two blocks of angle clips are supported and block the two ends at the bottom of Rail respectively, and tighten the nut outside angle steel so that it is card jail；
2, railway roadbed template is put to approximate location, knob long angle steel both sides nut, long angle steel is supported and is adjusted to railway roadbed template end face；
3, bolt is screwed into railway roadbed template end face and presets in bolt hole, fastening, then regulate long angle steel support both sides nut, it is achieved accurately adjust the function of template position；
4, each part dimension suitably can adjust according to engineering practice.
Embodiment 1
Attempt first using in I mark construction laid a railway track by track traffic Line 1 the second stage of the project main track in Ningbo; excellent effect; extend to each construction teams of full bid section subsequently, achieve significant effect, the most significantly improve railway roadbed size appearance quality; and drastically reduce the area template and run mould probability; work progress is controlled, additionally also helps keep the scene intact finished product and facility, intersects tradition facility; its service life is greatly improved, it is thus achieved that the extensive favorable comment of the constituent parts such as owner.
