Abstract
The utility model discloses a fixing frame for copper plates of a metro rail bed. The fixing frame is characterized in that a cantilever is arranged along a direction perpendicular to the direction of a steel rail, and a fixed end of the cantilever is provided with buckling blocks on the two sides of a steel track bottom plate respectively; the buckling blocks, which are fixedly arranged on the cantilever through buckling bolts, are clamped and fixed on the two side edges of the steel rail bottom plate; angle steel is positioned on one side of the metro rail bed, the angle steel and the cantilever form a T shape, and the horizontal right-angled edge of the angle steel is fixedly arranged at a free end of the cantilever; the vertical right-angled edge of the angle steel is provided with copper plate mounting holes at intervals; each copper plate is fixedly arranged on the side part of the angle steel through the copper plate mounting holes and the copper plate bolts. According to the fixing frame, the height and front-back positions of the rail bed copper plates and the distance between the rail bed copper plates and the steel rail can be accurately controlled under the positioning and the constraint of the fixing frame, so that the working efficiency can be greatly improved and the construction quality of the copper plates is guaranteed.
Description
Technical field
The utility model relates to a kind of underground railway track railway roadbed bronze medal fixed mount, more specifically says for the fixing fixed mount of bronze medal in both sides, underground railway track railway roadbed shrinkage joint.
Background technology
In prior art, for fixing of bronze medal on underground railway track railway roadbed, be mainly by adjusting the position of railway roadbed reinforcing bar, bronze medal roughly to be adjusted to the right place, cannot carry out the fixing of horizontal absolute altitude and lateral attitude to bronze medal two ends.The adjustment of this mode is meticulous not, can not accurately control bronze medal position and fix according to designing requirement, and in railway roadbed concreting process, bronze medal still can be moved, and early stage, adjustment work was not often prove effective.This make to utilize bronze medal that traditional approach is fixed after the construction that completes railway roadbed concreting, occur that bronze medal height is uneven, bronze medal distance in front and back is near or far away, and rail apart from or the phenomenon of left or right, had a strong impact on presentation quality.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, and a kind of underground railway track railway roadbed bronze medal fixed mount is provided, and by the permanent position of effective control bronze medal, improves the installation degree of accuracy of bronze medal, improves engineering presentation quality.
The utility model is that technical solution problem adopts following technical scheme:
The design feature of the utility model underground railway track railway roadbed bronze medal fixed mount is:
One cantilever, along perpendicular to rail move towards direction setting, the both sides that are positioned at rail base plate at the fixed end of described cantilever arrange respectively withholds piece, by withholding the piece of withholding that bolt is fixedly installed on cantilever, fixes the dual-side at described rail base plate;
One angle steel, be positioned at underground railway track railway roadbed a side, with described cantilever be "T"-shaped setting, the right-angle side that described angle steel is level with it is fixedly installed on the free end of cantilever, in described angle steel, be interval on vertical right-angle side bronze medal installing hole is set, each bronze medal is fixedly installed on the sidepiece of angle steel by bronze medal installing hole and bronze medal bolt.
The design feature of the utility model underground railway track railway roadbed bronze medal fixed mount is also: described cantilever is set to the adjustable Double layer Bar of thickness, and the Double layer Bar of different-thickness is corresponding to the different setting height(from bottom) of bronze medal.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model make bronze medal under the location of bronze medal fixed mount and constraint, can accurately control the height, front and back position of bronze medal, with the design objectives such as distance of rail;
2, the utility model can the lateral pressure when building railway roadbed concrete not be shifted bronze medal after completing adjustment;
2, the utility model mounting means simple and fast, degree of regulation is high, cheap is convenient to promote the use of.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is the utility model plan structure schematic diagram;
Number in the figure: 1 cantilever; 2 withhold piece; 3 withhold bolt; 4 angle steel; 4a is the right-angle side of level; 4b is vertical right-angle side; 5 set bolts; 6 bronze medal bolts; 7 cushion blocks; 8 rail; 9 bronze medals.
The specific embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, the form of structure of underground railway track railway roadbed bronze medal fixed mount is:
Cantilever 1 is along moving towards direction setting perpendicular to rail 8, the both sides that are positioned at rail base plate at the fixed end of cantilever 1 are respectively arranged with fixing hole, by fixing hole with withhold the piece 2 withheld that bolt 3 is fixedly installed on cantilever 1 and fix the dual-side at rail base plate, fixed end with this by cantilever 1 is fixedly installed on the bottom of rail 8, be provided with cushion block 7 withholding between piece 2 and cantilever 1, the setting of cushion block 7 is for adapting to the thickness of rail base plate.
Angle steel 4 be positioned at underground railway track railway roadbed a side, with cantilever 1 be "T"-shaped setting, the right-angle side 4a that angle steel 4 is level with it is fixedly installed on the free end of cantilever 1, in angle steel 4, be interval on vertical right-angle side 4b bronze medal installing hole is set, each bronze medal 9 is fixedly installed on the right-angle side 4b that is vertical in angle steel 4 by bronze medal installing hole and bronze medal bolt 6.
In concrete enforcement, the length of cantilever 1 is to determine to the distance of rail 8 according to designing requirement bronze medal 9, in the present embodiment, cantilever 1 is set to the adjustable Double layer Bar of thickness, by the Double layer Bar of different-thickness is set, obtains corresponding bronze medal setting height(from bottom); In order to make the permanent position between each member obtain the adjustment of certain limit according to designing requirement, it is strip hole that each fixing hole and installing hole are set.
Installation process:
1, withholding boring on piece 2, by withholding bolt 3, the fixed end of cantilever 1 is being fixed under rail base plate;
2, by set bolt 5, angle steel 4 is to the free end that " T " is fixedly mounted on cantilever 1;
3, adjust and be connected to the bronze medal 9 on railway roadbed reinforcing bar, by bronze medal bolt 6, two adjacent bronze medals are fixed on to the sidepiece of angle steel 4;
4, complete location and the installation of bronze medal 9.
By solid concrete roabed 2km model section bronze medal size is checked and accepted, do not find bronze medal displacement phenomenon, the bronze medal concrete size qualification rate that leaks outside is 100%, meets bronze medal mounting design and code requirement.The 70% dismountable bronze medal fixed mount in rear that reaches design strength after solid concrete roabed concreting, fixed mount is taked pressing type in rail foot, does not affect the use of rail later stage.
