Description
Technical field
It is the present invention relates to reinforced concrete prefabricated board technical field, in particular to a kind of for the novel of assembled track plates
Reinforced concrete plinth plate.
Background technique
With the development of China Railway High-speed technology, plate-type ballastless track is that the country applies more in inter-city passenger rail construction
Extensive primary trace form.Precast track plate has formed the factorial production, production technology level and structure size precision at present
It greatly improves, still, at present in country's high-speed railway and PDL Construction design and construction, it is small that there are sweeps, superelevation value
Big feature, track foundation are easy the influence due to constructing operation precision and loading end during filling concrete, how to mention
High orbit board concrete base-plates surface irregularity degree improves board-like assembling quality, guarantees the stability in railway operation, is current
Assembled plate track construction main problem urgently to be solved.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of reinforced concrete prefabricated board pedestal and its lifes
Production method solves assembled track plates pedestal since installation structure of track caused by surface irregularity occurs being displacement, dimension
The problems such as repairing train stability in difficult and railway operation.
The technical solution of the present invention is as follows: a kind of novel reinforced concrete base plate for assembled track plates, described new
Steel bar concrete pedestal plate includes plate body, built-in fitting, groove, cushion cap, door rebar and isolation bed course；Among the plate body surface
Equipped with several grooves, plate body two sides are equipped with cushion cap, and groove is located between the cushion cap of two sides；The cushion cap of the two sides is in plate body
Heart line is arranged symmetrically there are four built-in fitting, is additionally provided with isolation bed course on the cushion cap；Regular reinforcement is configured with inside the plate body
Skeleton, plate body bottom also extend configured with door rebar.
Preferably, the built-in fitting is adjustable elevation tapped through hole.
Preferably, the cushion cap is 1.5~2.5mm higher than plate body, and flatness is not more than 1mm.
Preferably, the novel reinforced concrete base plate length is 4200~6500mm, and width is 2000~3000mm,
With a thickness of 60~80mm.
The beneficial effects of the present invention are: 1, reinforced concrete plinth plate of the invention, in configuration regular reinforcement skeleton premise
Under, reasonable disposition extends regular reinforcement under plate body, improves the ductility and globality of concrete pedestal, effectively absorbs and dissipates and vibrates
Energy.
2, reinforced concrete plinth plate is by pre-buried adjustable elevation tapped through hole, by adjusting base plate elevation, positioning,
Then plate body bottom carries out concreting, so as to form concrete pedestal surface irregularity precision is high, intensity is high and surface
The features such as without laitance, not only increases concrete pedestal structure durability, and due to the flatness of fabricated base plate surface essence
Degree is high, and the steady of train in the precision and road transport row of track plates assembly in conjunction with the track plates of the factorial production, can be greatly improved
Qualitative and security performance.

Fig. 3 is the cross-sectional view of B-B in Fig. 1.
Fig. 4 is that novel reinforced concrete base plate of the invention installs schematic cross-sectional view.
Appended drawing reference: plate body 1, built-in fitting 2, groove 3, cushion cap 4, door rebar 5, isolation bed course 6, concrete pedestal 7, track
Plate 8, rail and fastener 9.
Specific embodiment
The implementation structure of the utility model is described below in conjunction with attached drawing.
As shown in Figures 1 to 4, the present invention for assembled track plates novel reinforced concrete base plate include plate body 1,
Built-in fitting 2, groove 3, cushion cap 4, door rebar 5 and isolation bed course 6；Several grooves 3 are equipped among 1 surface of plate body, 1 two sides of plate body are set
There is cushion cap 4, groove 3 is located between the cushion cap 4 of two sides；The cushion cap 4 of two sides is arranged symmetrically with the center line of plate body 1 there are four pre-buried
Part 2 is additionally provided with isolation bed course 6 on cushion cap 4；Regular reinforcement skeleton is configured with inside plate body 1,1 bottom of plate body, which also extends, to be configured with
Door rebar 5.
Further, built-in fitting 2 is adjustable elevation tapped through hole.
Further, cushion cap 4 is 1.5~2.5mm higher than plate body 1, and flatness is not more than 1mm.
Further, novel reinforced concrete base plate length is 4200~6500mm, and width is 2000~3000mm, thick
Degree is 60~80mm.
Fig. 4 is that novel reinforced concrete base plate of the invention installs schematic cross-sectional view, it can be seen that the art of this patent
The reinforced concrete plinth plate of production, using board-like carry out track construction is assembled, be a kind of railway roadbed can repair, replaceable track
Bed course 6, concrete pedestal plate, concrete pedestal 7 is isolated under fastener 9, plate by the rail on track plates 8 and its plate in structure
Composition, its working principle is that: pave the concrete pedestal 7 constructed on roadbed, tunnel floor or bridge floor, and concrete pedestal 7 is logical
Prefabricated reinforced concrete plinth plate is crossed, base plate surface smoothness is millimeter magnitude, logical by pre-buried adjustable elevation screw thread
Hole adjusts flatness, and isolation bed course 6 is placed on concrete pedestal plate two sides cushion cap 4.The track assembled using this technology
Structure solves plate orbit form since the stability and the main of safety that concrete pedestal flatness is inadequate and generates are asked
Topic is structurally characterized in that using precast reinforced concrete seat board surface smoothness, cooperates the factorial production track board size, table
The precision in face.Board-like assembling quality is improved, the art of this patent is suitable for ground line, overhead route, the shape of a hoof, circular tunnel etc..
The every mechanical property for showing novel reinforced concrete base plate of the invention with laboratory test is calculated by analysis inspection
Index is higher, and 28 days intensity of reinforced concrete plinth plate reaches 50Mpa or more, through on-the-spot test, the carrying feelings of analog orbit operation
Condition is tested by the power with one's hands behind one's back of assembled track plates carrying 200KN, and reinforced concrete plinth plate meets plate-type ballastless track knot
The requirement of structure.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The variation or simple replacement expected without creative work, should all be included within the scope of the present invention.
