Description
Technical field
The present invention relates to railroad tracks, more particularly to a kind of to reduce railway roadbed hurt and direct burial fastener system easy to install
System.
Background technology
For urban track traffic, state-owned railroads or magnetic railway, adopted in parking lot, rolling stock section and part main track location
With solid concrete roabed structure, and direct burial fastener system is matched, wherein more typical case is column check pit track.Using tradition
The monolithic roadbed track structure composition of direct burial fastener system includes rail, fastener, railway roadbed, not using sleeper.Rail uses
The new rails of 50kg/m or 60kg/m, fastener use reinforced concrete cast-in-situ structure using elastic separated rail fastening, solid concrete roabed.Fastener
Assembling section of track when direct burial is constructed, using form of construction work from top to bottom, fastener nylon sleeve is directly anchored in cast-in-place mixed
In solidifying soil.
By investigating a plurality of circuit to have put into effect, there is the following disease in traditional direct burial fastener system, led to
Analysis and summary are crossed, typical disease mainly there are following three aspects：(1) rubber cushion fails to fit closely with iron chair under iron chair, makes
When being poured into railway roadbed aggregate penetrate into binding face, when train passes through, iron chair lower part cannot uniform pressure-bearing, iron chair tilt
Cause service sleeve local pressure excessive, occur concrete cracking at casing；(2) nylon sleeve is crooked, and spiral shell is anchored in casing
The pulling capacity being not only vertically oriented that bolt is born, casing oblique loading during driving cause casing circumferential concrete to cleave；(3)
When pouring railway roadbed, fastener iron chair is buried by concrete, and the iron chair after burial and concrete form rigid overlap joint, but by
Under iron chair there is certain elasticity in rubber cushion, when train passes through iron chair to bottom offset, cause the concrete ring that contacts to
By shear stress, lead to concrete splitting.More than disease once being formed, will jeopardize traffic safety, even if original fastener direct-burried
Formula scheme does not cause to do over again in the construction time, is also not have fastener to replace condition in the operation phase, is brought greatly to operation maintenance
It is difficult.
Invention content
The technical problems to be solved by the invention, which are to provide, a kind of reduces railway roadbed hurt and direct burial fastener easy to install
System to ensure the normal service performance of fastener system, solves existing fastener system and concrete easily occurs in the construction stage together
Crackle and operation two benches cannot bring greatly just the technical barrier that it is repaired to line construction and operation maintenance
Profit.
The technical solution adopted by the present invention to solve the technical problems is as follows：
The a kind of of the present invention reduces railway roadbed hurt and direct burial fastener system easy to install, including fastener iron chair, absolutely
Edge backing plate, bolt sleeve and anchor bolt, insulating pad are set under fastener iron chair bottom surface, and bolt sleeve is embedded in concrete
In column, the lower part of anchor bolt passes through fastener iron chair and insulating pad to be threadedly coupled with bolt sleeve, it is characterized in that：It is described
Lower iron chair is set under insulating pad bottom surface, and the lower part of the lower bolster is sunk in concrete column, upper surface exposure concrete
Leg surface certain altitude；Anchor bolt mounting hole, bolt sleeve coaxial and that form stepped hole are opened up in the lower bolster plate face
Pipe location hole, bolt sleeve upper end shirt rim are pressed on the axial end wall in the stepped hole；The bolt sleeve top peripheral wall
Fluid sealant is perfused in gap between bolt sleeve location hole internal perisporium.
The plate face of the lower bolster is rectangular, and anchor rib, the upper end of each anchor rib and underlay are arranged at intervals on lower face
The lower face welding of plate.
The spiral bar on the bolt sleeve periphery is weldingly fixed on the lower bolster lower plate outside bolt sleeve location hole lower port
On face.
The beneficial effects are mainly as follows following aspects：
1st, after anchor bolt reinforcing, lower bolster makes insulating pad be tightly attached to fastener iron chair bottom surface, and the lower part of lower bolster sinks
Enter in concrete column, and upper surface then exposure concrete column surface certain altitude, avoiding insulating pad is contaminated, simultaneously
Fastener iron chair is avoided just to have taken with concrete；
2nd, bolt sleeve is by hoop constraint in the bolt sleeve location hole of lower bolster, and by reliable fixation, axis hangs down
It is no longer crooked directly in lower bolster plate face.The spiral bar on bolt sleeve periphery is weldingly fixed in the plate face of lower bolster, is effectively solved
The problem of spiral bar can not position；
3rd, lower bolster is flat surface, and condition is provided to fastener installation, replacement；The anchor welded on the lower face of lower bolster
Muscle is embedded in concrete column, is shared the larger pulling capacity that bolt sleeve is born jointly with spiral bar, be can effectively prevent bolt
Periphery of spigot concrete cracking.
The present invention has the characteristics that simple in structure, anti-cracking concrete effect is good, easy construction, and construction time unit is laid a railway track kilometer
About 300,000 yuan of construction cost can be reduced；Existing fastener system is solved together easily occurs concrete cracks and operation two in the construction stage
Stage cannot bring great convenience to the problem that it is repaired to line construction and operation maintenance；Economic and social benefit
Significantly, there is wide popularizing application prospect.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Referring to Figures 1 and 2, it is of the invention it is a kind of reduce railway roadbed hurt and direct burial fastener system easy to install, including
Fastener iron chair 20, insulating pad 21, bolt sleeve 24 and anchor bolt 27, insulating pad 21 are set to 20 bottom of fastener iron chair
Under face, bolt sleeve 24 is embedded in concrete column 10, and the lower part of anchor bolt 27 passes through fastener iron chair 20 and felt pad
Plate 21 is threadedly coupled with bolt sleeve 24.Lower bolster 22 is set under 21 bottom surface of insulating pad, and the lower part of the lower bolster 22 sinks
Enter in concrete column 10,10 surface certain altitude of upper surface exposure concrete column.Reference Fig. 2 and Fig. 3, Fig. 4, under described
Anchor bolt mounting hole 221, bolt sleeve location hole 222 coaxial and that form stepped hole, bolt sleeve are opened up in 22 plate face of backing plate
