Abstract

The utility model discloses a railroad concrete elastic sleeper which comprises a common concrete sleeper (1) and a resilient sleeper bearing (3) connected on the bottom surface of the common concrete sleeper (1), wherein, convex edges are manufactured in an area on which the bottom surface of the common concrete sleeper (1) is connected with the resilient sleeper bearing (3), and grooves corresponding to the convex edges are manufactured on the top surface of the resilient sleeper bearing (3). Since the structure not only has the advantages of simple molding and less material consumption, but also can increase the bonding area and the adhesive force between the connections; and therefore, the utility model has excellent working performance.

Description

Railway concrete elastic sleeper

Technical field

The utility model relates to a kind of railway that places the concrete sleeper of quarrel on the railway roadbed, particularly relates to a kind of railway concrete elastic sleeper.

Background technology

Have quarrel how to realize the locomotive high-speed cruising on the railway roadbed, reduce the locomotive high-speed cruising vibrations and noise, prevent ballast aggregate efflorescence and railway roadbed scleroma, the purpose that reduces the orbital maintenance expense, prolongs maintenance cycle? Japan adopt the Shinkansen as shown in Figure 5 ordinary concrete sleeper bottom surface and sleeper two downsides cover the method that places the elastic caoutchouc backing plate solved effectively more than these problems, but this method can expend the also more complicated of mode of elastomeric material, its global formation of a lot of preciousnesses.

The utility model content

The purpose of this utility model provides a kind ofly can save valuable elastomeric material, moulding is simple, integral body is connected firmly railway concrete elastic sleeper.

For achieving the above object, the technical solution of the utility model is a kind of railway concrete elastic sleeper, comprise ordinary concrete sleeper and the resilient sleeper-bearing that is connected ordinary concrete sleeper bottom surface, it is shaped on fin on ordinary concrete sleeper bottom surface and zone that resilient sleeper-bearing is connected, the resilient sleeper-bearing end face is shaped on the groove with the fin corresponding matching.

Described a kind of railway concrete elastic sleeper, its fin is distributed in ordinary concrete sleeper bottom center both sides.

Described any railway concrete elastic sleeper, its fin width vertically runs through ordinary concrete sleeper bottom thickness.

Described any railway concrete elastic sleeper, its fin width is positioned at the middle part of ordinary concrete sleeper bottom surface longitudinal thickness.

Described any railway concrete elastic sleeper, its resilient sleeper-bearing end face groove have many, and gash depth is that 2～5mm, width of rebate are that 3～8mm, separation are 10～20mm; Groove shape can for U font, V font, circular arc, rectangle and trapezoidal in any one.

Described any railway concrete elastic sleeper, its fin are the organic lining bottom surface that is fixedly connected on ordinary concrete sleeper inside.

Because it is that the resilient sleeper-bearing end face that is embedded in organic lining bottom surface in the sleeper, breaks the whole up into parts is shaped on fin and plugs together bonding groove that sleeper of the present utility model bottom surface is shaped on fin, fin, not only moulding is simple for such structure, materials are few, can also increase the bond area between the attachment, bonding force and the bonding affinity between the enhancing attachment, the utlity model has excellent service behaviour thereby make.

The specific embodiment

Embodiment one: the utility model resilient sleeper-bearing 3 is made by engineering plastics by rubber, organic lining 2, if with II type concrete sleeper is sample, as depicted in figs. 1 and 2, resilient sleeper-bearing 3 has two, every is that length is that 800mm, Breadth Maximum are that 270mm, minimum widith are the isosceles trapezoid of 230mm, its thickness is 10mm, every resilient sleeper-bearing 3 end faces are shaped on groove, it is that 64, width of rebate are that 6mm, bottom land width are that 12mm, groove depth are 3mm than the little 2mm of width of rebate, separation that groove is U word shape, quantity; Bottom center both sides pre-buried two organic linings 2 of concrete sleeper 1, each organic lining 2 bottom surface is shaped on the fin with arbitrary resilient sleeper-bearing 3 end face groove corresponding matching, the fin width vertically runs through ordinary concrete sleeper 1 bottom thickness, the shape of fin, quantity and rib are wide consistent with groove, and all the other sizes and the groove of fin are close; Plug together bondingly by fin and groove, resilient sleeper-bearing 3 links together securely with the organic lining 2 that is embedded in the ordinary concrete sleeper 1.

Embodiment two: the utility model resilient sleeper-bearing 3 is made by engineering plastics by rubber, organic lining 2, if with II type concrete sleeper is sample, as shown in Figure 3 and Figure 4, resilient sleeper-bearing 3 has two, every is that length is that 800mm, Breadth Maximum are that 250mm, minimum widith are the isosceles trapezoid of 210mm, its thickness is 10mm, every resilient sleeper-bearing 3 end faces are shaped on groove, it is that 64, width of rebate are that 6mm, bottom land width are that 12mm, groove depth are 3mm than the little 2mm of width of rebate, separation that groove is U word shape, quantity; Bottom center both sides pre-buried two organic linings 2 of concrete sleeper 1, each organic lining 2 bottom surface is shaped on the fin with arbitrary resilient sleeper-bearing 3 end face groove corresponding matching, the fin width is positioned at the middle part of ordinary concrete sleeper 1 bottom surface longitudinal thickness, be all not run through ordinary concrete sleeper 1 bottom thickness before and after the fin, the shape of fin, quantity and rib are wide consistent with groove, and all the other sizes and the groove of fin are close; Plug together bondingly by fin and groove, resilient sleeper-bearing 3 links together securely with the organic lining 2 that is embedded in the ordinary concrete sleeper 1.

Embodiment three: on the basis of embodiment one, cancel organic lining 2, former organic lining 2 is combined together with former ordinary concrete sleeper 1, become new ordinary concrete sleeper 1.

Embodiment four: on the basis of embodiment two, cancel organic lining 2, former organic lining 2 is combined together with former ordinary concrete sleeper 1, become new ordinary concrete sleeper 1.
