Abstract
The present invention relates to a kind of modular non-fragment orbit plate stitch filleting plates, the filleting plate is suitable for the filling and closing of modular ballastless track bed board or base plate plate stitch, is multilayer plate structure, and centre is polyethylene foam sheet, two sides is cutting plate, and cutting plate surface has the cutting of bar shaped；The area of cutting plate is greater than the area of polyethylene foam sheet, forms groove in filleting edges of boards edge, is filled with caulking material in groove.The present invention is convenient for site operation, live plate stitch can be greatly reduced into seam and filling closing workload, and can greatly improve filling and the seal quality of non-fragment orbit plate stitch.
Description
Technical field
The invention belongs to track engineering technical fields, and in particular to a kind of modular non-fragment orbit plate stitch filleting plate.
Background technique
Non-fragment orbit has continous way and two kinds modular, and continous way non-fragment orbit contraction crack is more, and crack repairing is too late
When will affect the durability of non-fragment orbit, and once sedimentation or protuberance occur for basis, and the trimming of continous way non-fragment orbit is difficult, influences
Range is big and cost is higher.Therefore, China gradually starts to promote using modular non-fragment orbit at present.
Modular non-fragment orbit causes disease to prevent rainwater or water seepage of tunnel from penetrating into railway roadbed bottom, while to improve railway roadbed
Overall stability, by ballastless track bed board or base plate plate stitch lower part using polyethylene foam sheet or the filling of pitch plank,
Top is sealed using caulking material, and the major defect of two schemes is as follows:
(1) " polyethylene foam sheet filling, caulking material closing " scheme
Such filling and closure solutions are that the current modular non-fragment orbit of state's iron the most commonly used road bed board or base plate plate stitch are filled out
It fills and closure solutions, but during constructing at the scene, since site operation dust is more, the cleaning of non-fragment orbit plate stitch concrete
Spend poor, and its aridity is often difficult to meet design requirement, leads at plate stitch that there are universal off-seam phenomenons for caulking material.Together
When, relative complex at the technique of seam using Overall Steel Formwork since plate stitch width is smaller, easily there is plate stitch road bed board nearby in scene
Or the phenomenon that base plate chip off-falling, or even often occur using polyethylene foam sheet directly as formwork for joint forming, it is whole to avoid extracting
Body steel form and the complicated procedures of forming for clogging polyethylene foam sheet, since polyethylene panel stiffness is smaller, in concrete vibrating mistake
It will lead to plate stitch skew in journey, seriously affect the quality and appearance of road bed board or base plate.
(2) " filling of pitch plank, caulking material closing " scheme
Such filling and closure solutions are that modular road bed board is the most normal in the running tunnel of current domestic city rail traffic underground
Plate stitch fills closure solutions.Since the rigidity of pitch plank is larger, and there is good antiseptic property, it can be directly as
Formwork for joint forming uses, the complicated procedures of forming for avoiding and extracting whole punching block, clog polyethylene foam sheet, and road bed board plate stitch it is linear and
The available good control of quality.But main problem existing for the program is that the flexible ability of pitch plank is poor, it is difficult to be adapted to
The biggish location of temperature difference, and the cohesive force between plank and caulking material is larger, when road bed board stretches, pitch plank meeting
The free extension of caulking material is limited, caulking material inevitably will appear off-seam phenomenon at plate stitch.
Summary of the invention
The object of the present invention is to provide a kind of modular non-fragment orbit plate stitch filleting plates, are not only convenient for site operation, but also can
The filling of non-fragment orbit plate stitch and seal quality are improved, defect in the prior art is overcome.
The technical scheme adopted by the invention is as follows:
Modular non-fragment orbit plate stitch filleting plate, it is characterised in that:
The filleting plate is suitable for the filling and closing of modular ballastless track bed board or base plate plate stitch, is multilayer plate knot
Structure, centre are polyethylene foam sheet, and two sides is cutting plate, and cutting plate surface has the cutting of bar shaped.
The area of cutting plate is greater than the area of polyethylene foam sheet, forms groove in filleting edges of boards edge, is filled in groove
Caulking material.
Polyethylene foam sheet edge is convex-shaped arc surface, and after filling caulking material, caulking material upper and lower surface is respectively formed spill
Cambered surface.
Cutting plate is steel plate, composite plate or hard plastic board.
Cutting plate thickness is 2-5mm, and cutting spacing is 50-100mm, and groove depth is the 1/3-1/2 of cutting plate plate thickness.
Polyethylene foam sheet is hole-closing structure.
Width, length, thickness and the shape of filleting plate are consistent with plate stitch concrete shape.
Neoprene glue sticking is used between polyethylene foam sheet and cutting plate.
The invention has the following advantages that
The present invention is suitable for the filling and closing of modular ballastless track structure road bed board or base plate plate stitch, applies convenient for scene
Work can be greatly reduced live plate stitch into seam and filling closing workload, and can greatly improve the filling and envelope of non-fragment orbit plate stitch
Close quality.

Specific embodiment
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of modular non-fragment orbit plate stitch filleting plate, the filleting plate is suitable for modular no tiny fragments of stone, coal, etc. rail
The filling and closing of road road bed board or base plate plate stitch are multilayer plate structure, and centre is polyethylene foam sheet 3, and two sides is to carve
Frid 2.Polyethylene foam sheet 3 is hole-closing structure, and 2 surface of cutting plate has the cutting 4 of bar shaped.The width of filleting plate, length, thickness
Degree and shape are consistent with plate stitch concrete shape, can be designed not according to road bed board or base plate weathering or the facilities of superelevation
Same cross-sectional form.Neoprene glue sticking is used between polyethylene foam sheet 3 and cutting plate 2.
The area of cutting plate 2 is greater than the area of polyethylene foam sheet 3, forms groove, filling in groove in filleting edges of boards edge
There is caulking material 1, polyurethane material, silicone or other high molecular material perfusions with equal performance can be used in caulking material 1
Forming.3 edge of polyethylene foam sheet is convex-shaped arc surface, and after filling caulking material 1,1 upper and lower surface of caulking material is respectively formed spill
Cambered surface.
Cutting plate 2 is steel plate, composite plate or hard plastic board.For cutting plate 2 with a thickness of 2-5mm, 4 spacing of cutting is 50-
100mm, 4 depth of cutting are the 1/3-1/2 of 2 plate thickness of cutting plate.Cutting 4 can enhance cutting plate and cast-in-place concrete road bed board or bottom
Bonding between seat board be bonded.
