Description
Technical field
The utility model relates to a kind of insulation joint pillow.
Background technology
In prior art, insulation joint connects wire across during track being naked being exposed on the external, namely be symmetrical arranged fluted at the sidepiece of sleeper, insulation joint connects wire and is arranged in groove, the mounting means of this structure is when constructing, some large-scale apparatuses are easy to cause damage to wire, shorten wire application life, and the cover plate sealed can be installed in the groove outside of conducting wire, but can the wasting of resources be caused so again, and be not easy to safeguard.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned defect, provide a kind of easy for installation, be easy to safeguard, the insulation joint of saving resource pillow.
In order to solve the problems of the technologies described above, the utility model comprises the sleeper body of being built by steel concrete, its design feature is: described sleeper body interior is provided with the conduit that can pass for insulation joint connecting line, and the both ends of described sleeper body are provided with seal.
Described conduit is symmetrical and be set in parallel in the both sides of sleeper body.
Described conduit comprises and to arrange along sleeper body length direction and the flat segments of stretching out from sleeper body one end and upwards extension and stretch out the vertical section of sleeper body outer surface.
Described flat segments and the angle vertically between section are 135 °.
The upper surface at described sleeper body two ends is respectively equipped with the rail support groove for attachment rail, and described seal is the pre-buried insulation sleeve be embedded in two rail support grooves.
Compared with prior art the utility model has the following advantages: conduit is symmetricly set on the both sides of sleeper body, and be embedded in the inside of sleeper body, insulation joint connects wire through conduit across track, when can prevent from constructing, large-scale apparatus causes damage to connection wire, and is convenient to safeguard; The upper surface at sleeper both ends is provided with the pre-buried insulation sleeve for attachment rail, and insulation effect is good.
