Abstract
An H type column single column double plate wave shaped joist steel safety guard belongs to road safety device, which is designed to solve the problem of the prior w plate wave bridge safety guard adopted in national highway central separation belt safety guard which can not hinder the large vehicle out of control, in particular break of large coach passing through central separation belt to the opposite road. The utility model is characterized in that a single column double plate shape is adopted, a rectangular cylinder shape steel hinder-proof bloc is arranged between a wave plate and a vertical pole and a ''Z'' type connection support is arranged on span of neighbored vertical pole. The utility model adopts the computer simulation to optimize the choice and validates by real vehicle crash experiments, thereby effectively improving crash-proof capability of the wave plate safety guard which is up to 230 kJ capable of resisting crash of large coach of 14 t, 60 km/h and twenty degree. The utility model has a little occupation and is in particular fit for region of limited central separation belt space without affecting greening.
Description
Technical field
The utility model belongs to the road safety device, and is particularly a kind of along road extension or the continuity guardrail between the track.
Background technology
Development along with the highway in China carrier, motor bus and truck quality are increasing, 85% the motorbus speed of a motor vehicle has reached more than the 100km/h on the speedway, and existing guardrail type can not satisfy road traffic condition and the instructions for use that has changed.The present W Lamb wave ellbeam guardrail that adopted of China speedway median strip particularly, can not stop oversize vehicle out of control particularly motorbus pass through the median strip and swarm into the subtend track, thereby stayed accident potential to highway traffic safety.
The utility model content
The technical problems to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of energy rank of protecting higher, can resist the motorbus collision, is fit to the two Lamb wave ellbeam steel guard rails of single-column that use the speedway median strip.
The technical scheme that the utility model adopted is, a kind of two Lamb wave ellbeam steel guard rails of forming by column, waveform beam slab and link thereof of H type post single-column, the column that it is characterized in that it adopts the H type column that comprises 1 block of web, 2 blocks of wing plates, the outside at every block of wing plate of this H type column is respectively equipped with the waveform beam slab, and between the waveform beam slab of every side and column, the steel obstruction block is arranged all, adopt connector to be connected respectively between obstruction block and column, the waveform beam slab.Obstruction block is the rectangle tubular, this rectangle tubular obstruction block has a triangle top rake, the lower edge of this top rake is in the lower surface of obstruction block, the upper edge of this top rake is on the obstruction block face relative with the waveform beam slab, be positioned at the lower wave trough place of waveform beam slab, the angle of the hypotenuse of this top rake and obstruction block lower surface is good with 40～50 degree.Obstruction block connects with the bolt that adopts 1 diameter more than or equal to 14 millimeters being connected of waveform beam slab, and link position is at the trough place of ripple beam slab.The waveform beam slab adopts two ripple beam slabs, and its thickness is more than or equal to 3 millimeters.At the span centre of 2 whenever adjacent H type columns, be equipped with Z-shaped connection between the waveform beam slab of column both sides and support.
The utility model beneficial effect compared with prior art is the crashproof ability that it has improved corrugated beam steeled protection fence effectively, has brought into play the protective capacities of guardrail to greatest extent.The utility model has reduced to take up room because of the employing of the two plate forms of single-column, and the setting that Z-shaped connection is supported has reduced the column consumption, thereby under equal protection level, it has saved material effectively, has reduced the guardrail cost.The utility model is particularly suitable for limited space system area, median strip, and does not influence greening.The utility model adopts computer simulation technique to be optimized selection, and passed through the real vehicle collision test checking, protection energy rank can reach more than the 230kJ, can resist 14t, 60km/h, 20 ° the collision of motor bus, is applicable to the median strip in the higher highway section of motor bus proportion of composing.
