Description
Technical field
This utility model relates to railway double-block type ballastless track expansion joint technical field of construction, is specifically related to a kind of railway double
Block type ballastless track expansion joint controls device.
Background technology
Railway ballastless track be open to traffic after road speed all at more than 250km/h, the ride comfort of railway roadbed is just proposed by this
The highest requirement, and road bed board expansion joint quality be determine whether railway roadbed can persistently smooth out after railway operation deciding factor it
One.
Generally arranging the expansion joint of 20mm between double-block ballastless track bed board, expansion joint uses polyethylene foams plate
Joint filling, and use polyurethane sealing material to seal in the range of the 30 ~ 40mm of surface.Expansion joint the most straight, the concreting of construction
The crooked construction quality waiting common quality defect to have a strong impact on road bed board expansion joint of rear polyethylene foams plate, thus cause logical
Railway roadbed irregularity after car operation, the hidden danger causing travel safety is unimaginable.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of railway double block type ballastless rail
Expansion joint, road controls device, and after overcoming the most straight, the concreting of construction of prior art expansion joint, polyethylene foams plate is askew
Oblique shortcoming, has simple to operate, low cost, work efficiency height, good stability, safe and environment-friendly feature.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of railway double-block type ballastless track expansion joint controls device, and including fixed foam panel assembly, square steel both sides are each hangs down
Straight welding one L-type snap ring, each L-type snap ring and snap ring nut-welding, L-type buckle penetrates in snap ring nut, each L-type snap ring and
L-type snaps through fastening nut and is connected with lower fastening nut, and square steel center line both sides are respectively provided with a fixed foam panel assembly.
Described fixed foam panel assembly is welded into grooved by steel plate A, steel plate B, steel plate C, and suspension ring weld with steel plate B.
Described device is inserted expansion joint pre-embedded device by fixed foam panel assembly and cystosepiment uses.
Described device can adjust pre-buried height by upper fastening nut with lower fastening nut, and can be in straight, curved line location
Arbitrarily angled use.
Described L-type buckle is welded under railway roadbed template eaves and penetrates snap ring nut.
The beneficial effects of the utility model are:
This utility model, compared with present stage construction technology, has simple to operate, low cost, work efficiency height, good stability, peace
Entirely, the feature of environmental protection, the expansion joint after construction is not only straight along attractive in appearance, and quality disposably reaches 100% qualified, can extensively answer
It is used in the construction at railway double-block type ballastless track expansion joint.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is fixed foam panel assembly structural representation of the present utility model.
Wherein, 1 is L-type snap ring；2 is L-type buckle；3 is square steel；4 is snap ring nut；5 is upper fastening nut；6 is lower twisting
Jack panel；7 is steel plate A；8 is steel plate B；9 is steel plate C；10 is suspension ring；11 is fixed foam panel assembly.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further discussed below.
As it is shown in figure 1, a kind of railway double-block type ballastless track expansion joint controls device, including fixed foam panel assembly 11,
Square steel 3 both sides each vertical welding one L-type snap ring 1, each L-type snap ring 1 welds with snap ring nut 4, and L-type buckle 2 penetrates snap ring spiral shell
In female 4, each L-type snap ring 1 and L-type buckle 2 are connected with lower fastening nut 6 by upper fastening nut 5, and square steel 3 center line both sides are each
It is provided with a fixed foam panel assembly 11.
Described device is inserted expansion joint pre-embedded device by fixed foam panel assembly 11 and cystosepiment uses.
Described device can adjust pre-buried height by upper fastening nut 5 and lower fastening nut 6, and can be on straight, curved line ground
The arbitrarily angled use of section.
Described L-type buckle 2 is welded under railway roadbed template eaves and penetrates snap ring nut 4.
As in figure 2 it is shown, described fixed foam panel assembly 11 is welded into grooved, suspension ring by steel plate A7, steel plate B8, steel plate C9
10 weld with steel plate B8.
Operation principle of the present utility model is:
Processing expansion joint pre-embedded device and fixed foam panel assembly, and " L " type buckle is welded on railway roadbed template (this template
Be fixed at expansion joint) under eaves, polyethylene foams plate and expansion joint pre-embedded device are installed at expansion joint, and pass through
Upper and lower fastening nut adjusts its pre-buried height, inserts fixed foam panel assembly after tightening upper and lower nut, and pour and vibrate railway roadbed
Board concrete, removes fixed foam panel assembly, removes expansion joint pre-embedded device, road bed board after concrete strength reaches 2.5Mpa
Clog polyurethane sealing material after meeting the requirements the age of concrete again to seal,
First expansion joint pre-embedded device is fixed during construction, then fixed foam panel assembly is inserted expansion joint pre-embedded device and bubble
Foam plate, is dismountable fixed foam panel assembly after treating this block road bed board concrete vibrating, and expansion joint pre-embedded device treats coagulation
To reach 2.5Mpa rear dismountable for soil intensity, and it is close that road bed board clogs polyurethane sealing material after meeting the requirements the age of concrete again
Envelope.
