The specific embodiment
As shown in Figure 1, 2, the utility model provides a kind of steel bar girder sleeper, comprises two short sleeper pieces 1 and is connected to two truss between short sleeper piece 1, and each short sleeper piece 1 is interior has respectively two service sleeves 6;
Described truss is space truss, comprise that a upper strata indulges the vertical muscle of muscle 2, Liang Gen lower floor 3, two vertical dowels 4 and two horizontal dowels 5, every vertical dowel 4 connects the vertical muscle 3 of a upper strata vertical muscle 2 He Yigen lower floors, between the every vertical muscle 3 of the horizontal dowel 5 connection vertical adjacent Liang Gen of muscle 3 lower floor of adjacent Liang Gen lower floor, has two horizontal dowels 5.
The two ends of the vertical muscle 2 in upper strata are embedded in respectively described two short sleeper piece 1 inside, and the two ends of the vertical muscle 3 of lower floor are passed respectively described two short sleeper pieces 1 and stretched out in outside two short sleeper pieces 1; The structure that the vertical muscle 3 of lower floor stretches out short sleeper piece 1 is conducive to when railway roadbed is built, and reinforcement the utility model is connected with railway roadbed;
Laterally the connected mode between dowel 5, vertical dowel 4, the vertical muscle 2 in upper strata, the vertical muscle 3 of lower floor is selected the firmly welding manner of safety;
The whole reinforcing bar trussed construction that welding forms can guarantee that the holding capacity of this structure and the ability of resistance to deformation are strong under the impact of external force in sleeper is being manufactured and constructed.
Short sleeper piece 1 is reinforced concrete block, configuration steel bar stress and structure muscle in it, its cross section is trapezoidal, its length is 560mm, upper wide be 280mm, lower wide be 300mm, be highly 170mm;
Each short sleeper piece 1 is interior is longitudinally embedded with two service sleeves 6, the upper port of service sleeve 6 is concordant with the upper surface of corresponding short sleeper piece 1, its lower port is enclosed in corresponding short sleeper piece 1 inside, and two service sleeves in each short sleeper piece adopt staggered to distribute;
Short sleeper piece upper surface can be shouderless or there is shoulder block, can supporting employing in-line arrangement and staggered fastener; On the other hand, short sleeper piece 1 determines that by adopted supporting fastener its upper surface track adopts plane or the inclined-plane tilting to truss direction, if rail cant is not set on fastener base plate, short sleeper piece 1 upper surface track need arrange the inclined plane consistent with rail cant to truss direction; If rail cant is set on fastener base plate, short sleeper piece 1 upper surface track is plane; Short sleeper piece 1 upper surface longitudinal edge rounding is processed, so that manufacture the demoulding, can prevent the phenomenon that causes arrisdefect owing to colliding with in transportation, installation process, falls piece simultaneously.The upper surface of the short sleeper of the present embodiment is the inclined-plane tilting to truss direction, and the gradient on this inclined-plane is consistent with the gradient of rail cant, and rail cant is not set on fastener base plate when mounted; Prefabricated by batch production high accuracy, meet the requirement to rail cant on short sleeper in operation.
The load capacity of a reinforcing bar or many combined reinforced bars is different, can determine according to concrete engineering situation; Between the vertical muscle 3 of the vertical muscle 2 in upper strata and lower floor of the present embodiment, be parallel to each other, the every vertical muscle 3 of the vertical muscle 2 in upper strata and lower floor is a reinforcing bar;
As shown in Figure 3, laterally dowel 5 is " Π " type; As shown in Figure 4, vertical dowel 4 is " π " shape; The dowel of these two kinds of shapes can play good reinforcement and supporting role to vertical muscle.
The present embodiment steel bar girder sleeper adopts batch production manufacture, can manufacture by the production technology of the short sleeper of urban track traffic and long sleeper, and manufacturing technique requirent is low.When steel bar girder sleeper is manufactured, adopt particular manufacturing craft, first steel bar girder, Structural Tectonics reinforcement installation are put in place, service sleeve 6 is accurately located, then fluid concrete, and carry out rational maintenance, by stripping forming.Steel bar girder sleeper cast on-site in concrete road bed, fastener for installing and rail on it.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
