Abstract
The utility model relates to a kind of road prevention device, particularly relates to a kind of crash barrier for roads, comprises column, column bottom mounting seat, it is characterized in that column there are two cross-drilled holes; Between two columns, cross bar is set, is fixed in the cross-drilled hole at two ends; Cross bar arranges vertical core, and vertical core internal fixtion has U-shaped steel bar; U-shaped steel bar is equally spaced.Crash barrier for roads of the present utility model, fixes all parts by perforate, durable, good impact resistance, and the life-span is long, substantially increases the security performance of guardrail.
Description
Technical field
The utility model relates to a kind of road prevention device, particularly relates to a kind of crash barrier for roads.
Background technology
Anticollision barrier belongs to public transport infrastructure, and it is the important leverage facility safeguarding and protect road safety.Crash barrier for roads acting as on road is distinguished track, is ensured that vehicle is by lanes, has ensured traffic safety.
Current anticollision barrier is that common steel bar is welded, and lighter impact force will cause guardrail to be out of shape or fracture, distortion place or the easy scratch automobile of breaking part; Accident vehicle cannot be stoped when impact is larger to jump out road, cause potential safety hazard.
Summary of the invention
Easily being out of shape the problem of fracture in order to solve existing anticollision barrier, the utility model proposes a kind of good impact resistance, the life-span is long, safety is higher crash barrier for roads.
Crash barrier for roads of the present utility model, comprises column, column bottom mounting seat, it is characterized in that column there are two cross-drilled holes; Arrange cross bar between two columns, cross bar inserts in the cross-drilled hole at two ends; Cross bar arranges vertical core, and vertical core internal fixtion has U-shaped steel bar; U-shaped steel bar is equally spaced.
As preferably, column is provided with reflective membrane, as warning mark, reminds car to note.
As preferably, crash barrier for roads of the present utility model, it is characterized in that base is square casting pig, casting pig bottom corner arranges leg.
As replacement, crash barrier for roads of the present utility model, it is characterized in that being provided with two universal wheels in base bottom, the line mid point of two universal wheel installation sites is positioned on the intersection point of cross bar, with self-locking device on universal wheel.In use, the crash barrier for roads that bottom arranges universal wheel can be moved away as required and become temporary export.
As preferably, crash barrier for roads of the present utility model, is characterized in that arranging helical spring at cross bar two ends.Helical spring contacts with column, and when being subject to lateral impact, helical spring compresses, and absorbs and clashes into kinetic energy, Self-bouncing after distress resolves, avoids guardrail to produce deformation.
Crash barrier for roads of the present utility model, fixes all parts by perforate, durable, good impact resistance, and the life-span is long, substantially increases the security performance of guardrail.
Accompanying drawing explanation
Fig. 1 is crash barrier for roads structural representation of the present utility model.
Fig. 2 is the structural representation of the base of the utility model band universal wheel.
Wherein, column 1, base 2, cross bar 3, U-shaped steel bar 4, leg 5, universal wheel 6, helical spring 7.
Detailed description of the invention
Embodiment 1: crash barrier for roads of the present utility model, comprises column 1, and column 1 bottom mounting seat 2, is characterized in that column 1 there are two cross-drilled holes; Arrange cross bar 3 between two columns 1, cross bar 3 inserts in the cross-drilled hole at two ends; Cross bar 3 arranges vertical core, and vertical core internal fixtion has U-shaped steel bar 4; U-shaped steel bar 4 is equally spaced.Column 1 is provided with reflective membrane, as warning mark, reminds car to note.Base 2 is square casting pig, and casting pig bottom corner arranges leg 5.
Embodiment 2: crash barrier for roads of the present utility model, comprises column 1, and column 1 bottom mounting seat 2, is characterized in that column 1 there are two cross-drilled holes; Arrange cross bar 3 between two columns 1, cross bar 3 inserts in the cross-drilled hole at two ends; Cross bar 3 arranges vertical core, and vertical core internal fixtion has U-shaped steel bar 4; U-shaped steel bar 4 is equally spaced.Column 1 is provided with reflective membrane, as warning mark, reminds car to note.Base 2 is square casting pig, and casting pig bottom corner arranges leg 5.The line mid point that base 2 bottom is provided with two universal wheels, 6, two universal wheel 6 installation sites is positioned on the intersection point of cross bar 3, with self-locking device on universal wheel 6.In use, the crash barrier for roads that bottom arranges universal wheel 6 can be moved away as required and become temporary export.
