Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
According to shown in Fig. 1 to Fig. 5, fibre reinforced composites composite sleeper of the present utility model is described, be that the fiber reinforced material by leaching being stained with resin combination is wound on mould, through extruding, curing molding, the demoulding obtains; Comprise integrated upper pillow plate 1, lower pillow plate 2 and at least two sleeper beams 3, described sleeper beam 3 connects upper pillow plate 1 and lower pillow plate 2, forms the hollow sleeper with cavity.
The number of sleeper beam 3 is at least two, and when for two, sleeper beam 3 connects the corresponding both ends of upper pillow plate 1 and lower pillow plate 2, and forming overall housing is the square hollow sleeper with cavity.
When the number of sleeper beam 3 is greater than two, the wherein corresponding both ends of two sleeper beam 3 (being denoted as side sleeper beam 31) connection upper pillow plates 1 and lower pillow plate 2, forming overall housing is the square hollow sleeper with cavity; Remaining sleeper beam 3 (being denoted as middle sleeper beam 32) is distributed in the middle of two side sleeper beams 31, connects upper pillow plate 1 and lower pillow plate 2, composite sleeper is separated multiple cavity.
Particularly, synthesis tie as shown in Figure 1, comprises integrated upper pillow plate 1, lower pillow plate 2 and four sleeper beams 3; Described sleeper beam 3 connects upper pillow plate 1 and lower pillow plate 2, and junction 5 adopts rounding 6, forms the hollow sleeper with three cavitys.Wherein, in four sleeper beams 3, two of outside is side sleeper beam 31, and another two is middle sleeper beam 32; Upper pillow plate 1, lower pillow plate 2 and two side sleeper beams 31 form the sleeper frame of hollow sleeper.
In order to connect support fastener, on the side of cavity, connect boss 4, as support fastener anchor bolt fixed block at described sleeper beam.Particularly, as shown in the figure, at two side sleeper beam 31 inner surfaces, and two sides of two middle sleeper beams 32 connect projection 4.Further, at least 2 projections 4 can be connected on the same side of sleeper beam 3, connect support fastener neatly with more convenient.As shown in Figure 2, towards same described cavity, two relative sides of two adjacent sleeper beams connect two highly different boss respectively.More convenient as support fastener anchor bolt fixed block.
The ability of distortion is born further in order to increase fibre reinforced composites composite sleeper.Set up supporting floor 7, described supporting floor 7 is fastened between boss 4 times edges and the turning of described cavity along composite sleeper longitudinal direction, as shown in Figure 3.Or described supporting floor 7 is fastened between two boss 4 highly different on two relative sides along composite sleeper longitudinal direction, as shown in Figure 4.Add the performance of the anti-cross shear of composite sleeper.Described supporting floor adopts the sheet material of existing good-toughness.
The technical scheme more optimized is, fills filler 8, play certain supporting role in the cavity of described synthesis tie, strengthens the non-deformability of composite sleeper, improves the overall performance of composite sleeper.Described filler 8 can be high density polyurethane foam.Further, described filler 8 can also be moisture protected dry drying prescription, plays the effect of dry composite sleeper while playing a supporting role, and ensures the drying of composite sleeper, ensures its mechanical property.The cavity of whole composite sleeper can be filled by described filler 8.
For the composite sleeper having set up supporting floor 7, only can fill filler in the underlying space of supporting floor 7, while saving filler, play same supporting role, as shown in Figure 5.
