Curve type track slab with shoulder
Technical Field The invention relates to a rail, in particular to a intercity high-speed railway upper curve track laying of track section. Background Art Existing supporting table track rail supporting slot of the die on a die is an integral structure, the linear track this kind of structure is feasible, however for the intercity high-speed railway on the circular curve segment of track curve and the purposes of relaxation curve is no longer applied. High speed railway line straight section and the circular curve of the transition section between the section known as the relaxation curve, the relaxation curve laid on the paragraph referred to as relaxation curve track rail; the relaxation curve circular arc curve of the paragraph is standard, the standard circular arc curve laid on the paragraph referred to as curved linear track rail. Because different radian curve of the circuit, the required curve track plate is also different, in particular of the outer side of the relaxation curve to meet requirements of the bearing table increase caused by the elevated outer ultra-high changes. Content of the invention The aim of this invention: to provide a bearing having shoulder edges can be width and the height direction of the track according to the design requirements of the offset to adapt to track actual space linear need a retaining shoulder curved track of. The technical scheme of the invention is:a retaining shoulder curved track plate, includes a track plate, the two rows of the track rail is provided with a retaining shoulder table 1 the [...] the 38-1 [...] 42 of the track bottom slope; the rail is a retaining shoulder of each row of the two rows is arranged on the center line of the built-in sleeve of the track plate in the horizontal direction is a curve, the curve and the rail centre curve horizontal projection are in a concentric circle curve. That is to say each row of a retaining shoulder supporting table on the basis of the track plate track curve linear with a certain lateral offset. Each row of a retaining shoulder supporting table on in the direction of thickness of the track plate is curved, the curve and the rail centre curve vertical projection are in a concentric circle curve. That is to say each row of a retaining shoulder supporting platform in a track plate according to the height direction of the track curve linear have a certain raises the quantity. The track bottom surface of the bearing plate in the longitudinal direction of the pre-embedded with at least two rows of rectangular steel bar, the lower end of the rectangular steel exposed in vitro to the track board. The roadbed and the connection is more reliable. The longitudinal direction of the rail plate close to the edge of the bottom surface of the plate embedded with a row of rectangular steel bar. The beneficial results of this invention are: the bearing having shoulder edges can be width and the height direction of the track according to the design requirements of the offset to adapt to track actual space linear needs. Below and in conjuction with the specific embodiment of the invention further description. Description of drawings Figure 1 is a structure diagram of the embodiment of the invention 1; Figure 2 is a top view of Figure 1; Figure 3 is a side view of Figure 2; Figure 4 is a structure diagram of the embodiment of the invention 2; Wherein the marks on the attached: 1 is the orbit plate, 2 the rail shoulder, 3 for axle foothill , 4 the central curve for the steel rail horizontal projection, 5 the vertical projection of the center curve for the steel rail, 6 is a rectangular steel bar, 7 the sleeve are pre-embedded. Mode of execution Embodiment 1 As shown in fig. 1 to fig. 3 is shown, a retaining shoulder curved track plate, also called a retaining shoulder curved linear track plate, includes a track plate 1, the track plate 1 of a rail two rows of shoulder 2 is provided with the table 1 the [...] the 38-1 [...] 42 of the track bottom slope 3 ; the rail is a retaining shoulder of each row 3 of the two rows are arranged on the center line of the built-in sleeve in the orbit plate 1 the horizontal direction is a curve, the curve of the horizontal projection the contours of center with the rail 4 are in a concentric circle curve. The track plate 1 close to the bottom surface of the edge position of the plate in the longitudinal direction of each built-in with a row of rectangular steel bar 6. Embodiment 2 As shown in Figure 4, a retaining shoulder curved track plate, also called a retaining shoulder easing curved track plate, includes a track plate 1, the track plate 1 of a rail two rows of shoulder 2 is provided with the table 1 the [...] the 38-1 [...] 42 of the track bottom slope 3 ; the rail is a retaining shoulder of each row 2 of the two rows are arranged on the center line of the built-in sleeve in the orbit plate 1 the horizontal direction is a curve, the curve of the horizontal projection the contours of center with the rail 4 are in a concentric circle curve, the rail with the retaining shoulder of each row 2 in the track plate 1 the thickness direction is a curve, the curve and the rail centre curve vertical projection 5 are in a concentric circle curve. The track plate 1 close to the bottom surface of the edge position of the plate in the longitudinal direction of each built-in with a row of rectangular steel bar 6. The embodiment of the picture is only an elevational view, a top view with the embodiment 1 Figure 2. Disclosed in this specification all characteristic of, or all of the steps in the method or process, in addition to the characteristic of the mutual exclusion outside and/or steps, may be combined in any way. The specification (including any additional claim, SUMMARY and with photos) is disclosed in any of the, unless the special description, can be other equivalent or with similar objectives alternative is to replace them. In other words, unless the special description, each feature only is a series of equivalent or similar characteristic in one of the examples. For this invention the stated above the better practical example , is not used to limit the invention, where in the present invention within the spirit and principle of the any modifications made by the, equivalent replacement and improved, and the like, shall be included in the scope of protection of this invention. The invention discloses a curve type track slab with shoulder, belonging to the track slab technical field. The track slab comprises a track slab body, the end part of the track slab body is provided with a groove, the two rows of track-bearing table boards with shoulders are provided with track bottom slope of 1:38-42; the central line of two rows of embedded sleeves arranged on each track-bearing table with shoulder is in curve distribution along the horizontal direction of the track slab body, the horizontal projections of the curve and the central curve of steel rail are concentric circle curves. The invention can deviate the track-bearing table with shoulder along the width and height directions of the track slab according to design requirement, so as to meet the requirement of physical space line shape of track. 1. A retaining shoulder curved track plate, includes a track plate (1), characterized in that said track plate (1) the two rows of the rail (2) is provided with the table 1 the [...] the 38-1 [...] 42 of the track bottom slope (3); each row of a retaining shoulder rail (2) is provided with two rows of pre-built sleeve (7) the center line of the fan the track (1) on the horizontal direction is a curve, the curve and the rail centre curve horizontal projection (4) are in a concentric circle curve. 2.
