Abstract
A track leveling support comprises an embedded part, one end of a bolt sleeve is fixed to a flat plate of the embedded part, the other end of the bolt sleeve is fixed to a sealed steel plate, a rolling straight thread connecting piece is fixed to the middle of the sealed steel plate and sleeved with a bolt through pipe, and a secondary grouting layer is arranged on the periphery of the bolt through pipe. A bolt bar matched with the rolling straight thread connecting piece is a full-threaded bolt bar, the lower end of the full-threaded bolt bar penetrates into the bolt sleeve, and the upper end of the full-threaded bolt bar stretches out of the bolt through pipe. The two sides of a track are respectively provided with one track leveling support. The bolt bar can be adjusted vertically; horizontal positioning of the bolt bar can be adjusted by bending the bolt bar appropriately, so that the embedded bolt bar is installed in a high-accuracy mode in the horizontal direction. In a modification project, the bolt bar can be adjusted vertically, after the original track is loosened and leveled and secondary grouting is performed again, the track can be fastened by using the original bolt bar, the construction period is shortened substantially, investment is saved substantially, and the track leveling support is convenient and rapid to use, safe and reliable.
Description
Technical field
The utility model relates to a kind of track leveling support.
Background technology
In thermal power plant construction process, often can run into all kinds of track pre-embedded bolt bar bars because adopting direct embedding manner, embedding precision is poor in the past, and the problem of bringing inconvenience is installed to track.As in the improvement project in later stage, directly bury underground and do not possess controllability because of bolt, even if the trace adjustment of track level measuring also has to bolt again to be buried underground, this has just caused the serious waste of resource.
Utility model content
For deficiency of the prior art, the utility model proposes a kind of track leveling support, this leveling support makes that pre-embedded bolt bar bar is upper and lower, level is all adjustable, has improved track installation accuracy, and more Late reformation engineering is provided convenience.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of track leveling support, it comprises built-in fitting, set bolt sleeve one end on the flat board of built-in fitting, bolt sleeve other end fixed closed steel plate, the fixing thread rolling bar joints part in sealing steel plate middle part, the form of thread angle of thread rolling bar joints part is 75o, and thread rolling bar joints part overcoat has bolt poling, and bolt poling periphery is secondary grout layer.The shank of bolt coordinating with thread rolling bar joints part is full screw bolt bar, and its lower end penetrates bolt sleeve, and bolt poling is stretched out in upper end.
Wherein, track leveling support respectively arranges one on track both sides.
Shank of bolt of the present utility model is adjustable up and down; By suitable bending shank of bolt, realize shank of bolt horizontal location adjustable, thereby the high accuracy realizing in pre-embedded bolt bar horizontal direction is installed.Simultaneously, in improvement project, this shank of bolt is adjustable up and down, is unclamping original track, by track leveling, re-starts that can to utilize original shank of bolt to carry out after back-grouting fastening, has significantly saved duration and investment, convenient and swift, safe and reliable.Meanwhile, the utlity model has simple structure, economical and practical, implement convenient, be convenient to transformation, especially in the improvement project of track foundation leveling, have more convenient and swiftly, safe and reliable, save the advantage of investment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: built-in fitting 1, bolt sleeve 2, thread rolling bar joints part 3, sealing steel plate 4, bolt poling 5, shank of bolt 6, secondary grout layer 7, track fastening 8, track 9.
The specific embodiment
As shown in Figure 1, a kind of track leveling support, it comprises built-in fitting 1, set bolt sleeve 2 one end on the flat board of built-in fitting 1, bolt sleeve 2 other end fixed closed steel plates 4, the fixing thread rolling bar joints part 3 in sealing steel plate 4 middle parts, the form of thread angle of thread rolling bar joints part 3 is 75o, thread rolling bar joints part 3 overcoats have bolt poling 5, and bolt poling 5 peripheries are secondary grout layer 7.The shank of bolt 6 coordinating with thread rolling bar joints part 3 is full screw bolt bar, and its lower end penetrates bolt sleeve 2, and bolt poling 5 is stretched out in upper end.Wherein, track leveling support respectively arranges one on track 9 both sides.
Bearing should first arrange built-in fitting 1 in bearing installation site while installation, bolt sleeve 2 lower ends and built-in fitting 1 are welded and fixed, bolt sleeve 2 upper ends are welded and fixed sealing steel plate 4, on sealing steel plate 4, be welded and fixed between two parties the thread rolling bar joints part 3 that tooth form angle is 75o, and the shank of bolt of full screw thread 6 is connected with thread rolling bar joints part 3, overlapped thread rolling bar joints part 3, and be welded and fixed bolt poling 5 on sealing steel plate 4 tops, the length of bolt poling 5 is determined according to the thickness of secondary grout layer 7.Lay after secondary grout layer 7, regulate its protruded length above secondary grout layer 7 by swivel bolt bar 6, realize the up-down adjustment of shank of bolt 6, the height of realizing track 9 both sides track fastenings 8 regulates and angle of inclination adjusting, and then improves the installation accuracy of track 9.In addition, suitably bend shank of bolt 6, the horizontal location that can realize shank of bolt 6 is adjustable, thereby the high accuracy realizing in pre-embedded bolt bar horizontal direction is installed.
