Technical field
The utility model relates to the framework section of track that a kind of double-block type ballastless track construction is used, and belongs to the double-block type non-fragment rail bed construction of China Railway High-speed CRTS-I type.
Background technology
The construction of paving method is changed in current double-block type non-fragment rail bed general employing, and the framework section of track of use generally has two kinds of the single-beam type framework section of track and the twin beams type framework sections of track, and two kinds of framework sections of track all exist different shortcomings.Between the long 6.0m-7.0m of the single-beam type framework section of track, utilize every group of single crossbeam to connect rail and form the section of track.Its shortcoming of the single-beam type framework section of track has three: one, whole group of section of track turnover accessory weight, and inconvenience is had bad luck at scene; The 2nd, from great, yielding, stability is lower; The 3rd, adjacent joint for track panel is many, unfavorable to the control of railway roadbed trajectory accuracy.Between the long 6.0m-7.0m of the twin beams type framework section of track, the structure and the rail that utilize every group of two crossbeams and crossbeam to connect system's combination are connected to form the section of track, and its shortcoming has four: one, whole group of section of track accessory weight, and inconvenience is had bad luck at scene; The 2nd, high from great cost; The 3rd, rigidity is high, on curve, uses and is difficult for curved putting; The 4th, adjacent joint for track panel is many, unfavorable to the control of railway roadbed trajectory accuracy.
Summary of the invention
The purpose of this utility model is, the framework section of track that provides a kind of double-block type non-fragment rail bed construction to use, this section of track, in the situation that reducing unit deadweight, has enough rigidity, and globality is strong, have bad luck at the scene of being convenient to, improve work efficiency, curved section is easy to use, and carries support and translation system, increase framework section of track length to reduce rail joint quantity simultaneously, make non-fragment orbit precision be easy to control.
The technical scheme of the framework section of track that double-block type non-fragment rail bed construction of the present utility model is used is as follows: it comprises twin beams framework, single-beam framework, twin beams framework connects into H type by 2 crossbeams and 1 longitude strut, wherein the each reserved rail of beam head is installed groove, connects to form framework by fishtail clamping plate and high-strength bolt and rail; Single-beam framework has 1 crossbeam, and the each reserved rail in crossbeam two is installed groove, connects to form framework by fishtail clamping plate and high-strength bolt and rail; The rail cant of rail is 1:40; Screw regulator is connected to the empty place of rail.
Crossbeam and longitude strut are made by the high channel-section steel of 18cm.
The quantity of twin beams framework is 4, and the quantity of single-beam framework is 1.
Compared with the prior art, the utility model is at the horizontal connecting elements that adopts the suitable high channel-section steel of 18cm of rigidity as the framework section of track, 60kg/m tool track is as longitudinal connecting component, be equipped with screw regulator vertical and lateral adjustments function simultaneously, integral rigidity is suitable, from heavy and light, can realize vertical and lateral adjustments.It is convenient that position is moved in screw regulator dismounting, can not only meet sleeper pitch and adjust section, and can change in time while damaging.The rail cant of the 1:40 that screw regulator carries plays and ensures the effect of tool track rail cant, after section of track framework forms, can ensure gauge, rail cant and rail smooth.The utlity model has the superiority such as simple in structure, installation and maintenance are easy, construction cost is low, have good popularization and applied value.
Below in conjunction with accompanying drawing, this is suitable for to novel concrete enforcement and describes.
