2006 year traffic Department of Transportation have issued the revision version < < highway traffic safety facilities design standard > > (JTG D81-2006) of < < expressway traffic safety facilities design and construction technical specification > > (JTJ074-94), < < highway traffic safety facility construction technique normalizing > > (JTG F71-2006), the related specifications such as < < Freeway Traffic Engineering and facilities design general specification > > (JTG D80-2006) along the line, largely safety protection facility anti-collision level is promoted, directly cause the highway barrier anti-collision level of building before 2006 not meet code requirement, also in the urgent need to promoting the crashworthiness of guardrail.
If original guardrail is removed and newly-built guardrail, can cause a large amount of waste of material, do not meet the demand for development of the structure green traffic transportation system proposing in communications and transportation " 12 " development plan.The subject matter running in guardrail transformation is exactly the not enough problem of height of guardrail, therefore the improvement cost of, develop that a kind of crashworthiness meets current specifications requirement, the fence upright that can make full use of again old guardrail component being increased structure and can farthest reduce safety device.
Utility model content
The purpose of this utility model is to design a kind of novel fence upright and increases structure, addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of fence upright is increased structure, comprises connecting elements, inner sleeve, increases sleeve pipe, screw rod, nut and be arranged on the column on basis, and described inner sleeve comprises inner sleeve and lower inner sleeve; Described lower inner sleeve is connected with described column by described connecting elements, described in increase sleeve pipe and described upper inner sleeve welds; Described screw rod and described upper inner sleeve weld together, and described nut and lower inner sleeve weld together, described in increase sleeve pipe and link together by screw rod and described nut and described column.
Described basis is for to beat pile type foundation, or pre-buried type basis.
The described sleeve pipe of increasing is outer tube.
Described increase sleeve pipe often rotate a circle promote height be 0-20cm.
Described lower inner sleeve is that bolt is connected or welds one kind of with the connected mode of column.
The screw thread of described screw rod and described nut is the one kind of of regular screw threads, trapezoidal thread or saw-tooth thread.
Described column, described in increase sleeve pipe and described inner sleeve is the one kind of of circle, rectangle, ellipse or flute profile.
The purpose of this utility model is to provide one and protects and block column and increase structure, the guardrail being applied in highway reconstruction and expansion process adds senior middle school, and this pillar construction good looking appearance can promote the protection of guardrail highly, order of severity when reduction accident occurs, reduces and protects the engineering quantity of blocking in transformation process.
Of the present utility model protecting blocked pillar construction, comprise column, increase sleeve pipe, connecting elements, inner sleeve, screw rod, nut, inner sleeve comprises inner sleeve and lower inner sleeve, welded nut being connected with column by connecting elements on lower inner sleeve, upper inner sleeve and outer tube welding, screw rod is welded on inner sleeve.
Rotatable after screw rod described above is connected with nut, in order to promote column height.
Column described above can be upright or have certain angle of inclination.
The sleeve pipe of increasing described above can be the one kind of of outer tube or inner sleeve.
Outer tube described above often rotate a circle promote height be 0-20cm.
Inner sleeve described above is that bolt is connected or welds one kind of with the connected mode of column.
The screw thread of screw rod described above and nut is the one kind of of regular screw threads, trapezoidal thread, saw-tooth thread.
Column described above, to increase sleeve pipe, inner sleeve be the one kind of of circle, rectangle, ellipse, flute profile.
The basis of column described above is pre-buried type basis or beats the one kind of of pile type foundation.
The beneficial effects of the utility model can be summarized as follows:
1, because column of the present utility model is increased structure, column has adopted the connected mode of bolt and nut, and outer tube and column have certain lap, and bonding strength is reliable; When column is increased at needs, can determine the height that column need to improve according to cover thickness, and realize (n*d1=cover thickness, wherein n is the number of turns, d1 is thread pitch) with the rotating cycle of outer tube.This structure can be reserved different casing length as required, and the needs that repeatedly overlay to meet following road surface are easy to operate, is not only applicable to being applied to the guardrail transformation of existing highway, for new highway, for meeting later overlay demand, also can adopt this structure.Exploitation of the present utility model meets the actual demand of highway in China development, is also adapted to different guard bar structure forms, and the economy when improving the integral protection ability of highway in China and improving highway reconstruction and expansion is highly profitable.
2, the utility model reasonable in design, simple and direct, can reach the effect of security protection, easy to operate and good looking appearance, and can realize quick, the low-carbon (LC) of maintenance, be a kind of protection effect significantly, the column of easy construction increases structure.
