Traffic guardrail belongs to public transport infrastructure, and it is the important leverage facility of safeguarding and protect road safety. Crash barrier for roads acting as on road distinguished track, ensured that vehicle, by lanes, has ensured traffic safety.
Current traffic guardrail is that common steel bar is welded, and lighter impulsive force will cause guardrail distortion or fracture, the easy scratch automobile of distortion place or breaking part; When impact is larger, cannot stop the accident vehicle road that jumps out, cause potential safety hazard. The patent No. is that the disclosed crash barrier for roads of ZL201420458077.9 junction all adopts plug-type connected mode, comparatively inconvenience when installation.
Summary of the invention
Easily be out of shape the problem of fracture for existing traffic guardrail, the utility model proposes a kind of good impact resistance, long, easy for installation high strength road isolation guardrail of life-span.
High strength road isolation guardrail of the present utility model, comprises column, and column bottom mounting seat is characterized in that column top arranges cross-drilled hole A, and cross-drilled hole A adopts rectangular opening, welding rectangle installation sheet in cross-drilled hole A; Cross-drilled hole B is arranged at column bottom, and cross-drilled hole B adopts circular port, is welded with arc installation sheet in cross-drilled hole B, and rectangle installation sheet and arc installation sheet protrude from column both sides, and screw is set;
Between two columns, cross bar A and cross bar B are set, cross bar A is flat metal bar, by bolted on rectangle installation sheet; Cross bar B is the cylindrical metal bar of hollow, cross bar B top by bolted on arc installation sheet; Vertical core is equidistantly set in cross bar B, in vertical core, inserts U-shaped steel bar fixing; U-shaped steel bar and cross bar A are by being welded to connect.
As preferably, on column, be provided with reflective membrane, as warning mark, remind car to note.
As preferably, crash barrier for roads of the present utility model, is characterized in that base is square casting pig, and casting pig bottom corner arranges leg.
As an alternative, crash barrier for roads of the present utility model, is characterized in that two universal wheels are installed in base bottom, and the line mid point of two universal wheel installation sites is positioned on the intersection point of cross bar, on universal wheel with self-locking device. In use, the crash barrier for roads that bottom arranges universal wheel can be moved away as required and become temporary export.
As preferably, column arranges spring rotary shaft in top, and reflective membrane band is set in spring rotary shaft, and reflective membrane band is fixed on the clip of column one side. Use reflective membrane band, can strengthen this guardrail visible at night degree, and in the time accepting Transverse Impact, bear certain cushioning effect.
Crash barrier for roads of the present utility model, fixes all parts by perforate, durable, good impact resistance, and the life-span is long, has greatly improved the security performance of guardrail; And isolation guardrail deadweight is lighter, be convenient to mobile and assembling.
