Description
Technical field
The utility model belongs to highway protective equipment, and in particular to a kind of composite highway protection safety pillar.
Background technology
In highway protective equipment, most of at present to use steel pillar and steel-guardrail, its anti-corrosion measure is typically adopted
Use galvanizing technique.But the problem of maximum, it is galloping process, strikes on fence upright, because guardrail is strong
Hard material, casualties is easily caused, while steel pillar weight is big, the zinc coat abrasion of transport installation process, corrosion resistance
Can be poor, steel does not possess energy absorption ability, and impact damage destroys big.
The content of the invention
The purpose of this utility model is to disclose the good composite of a kind of high-strength light, corrosion resistance and good, energy absorption performance
Highway protection safety pillar.
In order to solve the above problems, the utility model employs following technical scheme：
A kind of composite highway protection safety pillar, including cylinder and chassis, are made, chassis exists using glass steel material
Below cylinder, chassis and cylinder integral die shaping, cylinder is the cavity body of regular hexagon, and cylinder has on two relative faces
High-strength nut built-in fitting, to install protective plate use, there is bolt hole the corner on chassis.
A kind of above-mentioned composite highway protection safety pillar, the cavity body of described cylinder are interior from the poly- ammonia of underfill
Ester energy-absorbing material.
High-strength reinforcement is installed in a kind of above-mentioned composite highway protection safety pillar, the root in described six faces of cylinder
Muscle, enhancing root are supported.
A kind of above-mentioned composite highway protection safety pillar, the interior high-strength damping of installation of bolt hole on described chassis connect
Connection device, described high-strength damped junction device is from top to bottom bolt, composite material gasket, rubber shock-absorbing pad, composite wood
Backing strap piece, rubber protection pad piece.
A kind of above-mentioned composite highway protection safety pillar, described composite material gasket use stereo fabric system
Make, compression and stretching are not less than 300Mpa.
The utility model has advantage：Made using glass steel material, integral light is high-strength, fine corrosion resistance；Cylinder
High-strength reinforcement is installed in the root in six faces, and enhancing root is supported；Filled polyurethane energy-absorbing material, has column strength to work,
To automobile crash energy-absorbing function, reduce to greatest extent and car body is damaged, maximum safeguard protection personal security；High-strength damping connection dress
Put by impact process energetically, improve the overall stressing conditions on chassis, avoid local pressure, local laceration；As automobile is hit strongly
Hit, by composite structure cushioning effect, reduce impact.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Embodiment
Reference picture 1, cylinder 1 and chassis 2, are made using glass steel material, and chassis 2 is below cylinder 1, chassis 2 and post
The integral die shaping of body 1, cylinder 1 are the cavity body of regular hexagon, and cylinder 1 has high-strength nut built-in fitting 3 on two relative faces,
To install protective plate use, there is a bolt hole 5 corner on chassis 2, and the cavity body of cylinder 1 is from underfill polyurethane energy-absorbing material 4, post
High-strength reinforcement 6 is installed in the root in 1 six faces of body, and enhancing root supports that the high-strength damping installed in the bolt hole 5 on chassis 2 connects
Connection device is from top to bottom bolt 7, composite material gasket 8, rubber shock-absorbing pad 9, composite material gasket 10, rubber protection pad piece
11.Composite material light is high-strength, corrosion resistance and good, belongs to flexible material, and have good energy absorption performance.After shock,
By composite structure cushioning effect, there is energy-absorbing function to automobile crash, reduce to greatest extent and car body is damaged, maximum peace
Full guard personal security.
