Specific embodiment
With reference to the accompanying drawings and embodiments, the utility model is described in detail.
A kind of road guard-rail, as shown in Figure 1, including many protective fence units interconnected, a protective fence unit
Fig. 3 is shown in by fixing bolt 12(including the left and right sides) two pedestals 1 on road are fixed on, two pedestals 1, which run through, branch
Dagger 2 is equipped with guardrail 3 between two support columns 2.
As depicted in figs. 1 and 2, guardrail 3 includes about two cross bars 31 disposed in parallel, is opened up on two support columns 2
There are two upper and lower through slots 22 disposed in parallel for wearing cross bar 31；2 opposing rail 31 of support column is equipped with fastening part 23, makes cross bar
31 is stronger with the connection of support column 2.Fastening part 23 includes being provided on former and later two sides of the corresponding through slot 22 of support column 2
Fastening through-hole 231, fastening through-hole 231 is connected with through slot 22, while correspondence offers blind hole 315 on cross bar 31.Fastening
Through-hole 231 is equipped with fastening bolt 232, and fastening bolt 232 passes through fastening through-hole 231 and blind hole 315 and is threaded with fastening
Nut 233 is threadedly engaged connection with fastening nut 233 by fastening bolt 232, cross bar 31 is fixed on support column 2.
As shown in Figures 2 and 3, the both ends of cross bar 31 are respectively equipped with integrally formed groove connector 311 and connect with protruding head
First 312, the section of groove connector 311 is in concave character type, and the section of protruding head connector 312 is in convex.311 He of groove connector
Vertical connecting hole 314 is offered on protruding head connector 312.By the recessed of two cross bars 31 adjacent on two protective fence units
Slot connector 311 together with 312 joggle of protruding head connector so that the axis of two cross bars 31 on the same line after, pass through
Intert bolt in connecting hole 314, two protective fence units are linked together by bolt thread attaching nut.By groove connector
311 and protruding head connector 312 be arranged on the both ends of same root cross bar 31 can make its installation with replacement it is more convenient, without examining
Consider whether two cross bars 31 can match.
As shown in Fig. 2, several vertically disposed connecting tubes 32 are evenly arranged between two cross bars 31 along its length.
Symmetrically offer several blocked holes 313 on two cross bars 31, connecting tube 32 be connected to two blocked holes 313 symmetrical above and below it
Between, it is detachably connected between connecting tube 32 and cross bar 31, not only convenient transportation but also has facilitated the replacement of connecting tube 32.Connecting tube 32 is two
Hold the hollow tube of sealing, the both ends of connecting tube 32 are equipped with damping sleeve gasket 321 to provide cushion effect, can the reduction when colliding
Connecting tube 32 is to the impact force of cross bar 31, while connecting tube 32 is preferably zinc steel material, with improve the intensity of protective fence, hardness and
Service life.
As shown in Figure 2 and Figure 4, the both ends of connecting tube 32 are welded with end socket 323, are welded with one between two end sockets 323
Block wave-shape board 322, wave-shape board 322 are bent in sine curve by thin strip-shaped steel plate, and wave-shape board 322 is threaded through connecting tube 32
Inside.When each inflection point of wave-shape board 322 is connected on the inner wall of connecting tube 32 and installs by abutting towards protective fence
Former and later two faces can be very good the intensity of enhancing road guard-rail, make protective fence will not be easily in the shock by vehicle
Deformation or fracture, play a protective role to the pedestrian and vehicle safety of surrounding.Simultaneously as 322 company of being connected to of wave-shape board
On the inner wall of adapter tube 32, there is certain elastic deformation space in connecting tube 32, when Vehicular impact is on road guard-rail
So that elastic deformation occurs for wave-shape board 322 to realize buffering, and damping sleeve gasket 321 makes between connecting tube 32 and cross bar 31 in fact
It now buffers, injury of the road guard-rail to vehicle and its occupant can be reduced.
As shown in Figures 2 and 3, the bottom end of support column 2 is equipped with the idler wheel 21 that joint face is greater than 2 bottom surface of support column, pedestal 1
The corresponding convex through slot 13 that offers in inside be used to be clamped support column 2 so that being installed rear support strut 2 is fixed on pedestal
On 1.Pedestal 1 is equipped with shackle 11 away from the one end on ground, and mutually matched suspension hook 33 is equipped on the cross bar 31 of near-earth.Work as needs
When mobile road guard-rail, unclamps and pedestal 1 is fixed on the fixing bolt on road, the shackle 11 on pedestal 1 is hooked on suspension hook
Make pedestal 1 hanging on 33, expose the idler wheel 21 being connected in pedestal 1, pushes road guard-rail mobile.It is sticked on support column 2
There is reflective strip 24, when night road insufficient light, when lights of vehicle is radiated in reflective strip 24, passes through the anti-of reflective strip 24
Light action can remind the place of driver's road guard-rail, reduce the generation of accident.
Specific implementation process: protective fence unit is placed on desired position, will be on two neighboring protective fence unit
Groove connector 311 on two cross bars 31 is together with 312 joggle of protruding head connector, so that the axis of two cross bars 31 is same
After on one straight line, by interting bolt in connecting hole 314, two protective fence units are connected to one by bolt thread attaching nut
It rises.Each protective fence unit is successively interconnected to protective fence by this method.Protective fence is fixed on by fixing bolt 12
On road, the installation of road guard-rail is completed.When colliding, automobile has the power of an impact, connecting tube to protective fence
32 at first by impact force, 322 stress of wave-shape board being connected in connecting tube 32 at this time, at the inflection point of wave-shape board 322 generate with
The reaction force of impact force confrontation is to generate support force to the inner wall of connecting tube 32, enhances the intensity of connecting tube 32.Wave simultaneously
It is axially moved after the cambered surface decomposition impact force of the stress inflection point two sides of wave plate 322 along connecting tube 32 and generates deformation, vehicle is generated
Cushion effect reduces the secondary injury to vehicle and occupant.
Since connecting tube 32 is uniformly vertically set between two cross bars 31 side by side, can be incited somebody to action when 32 stress of connecting tube
Impact force passes to cross bar 31, and the conduction of impact force can be reduced by being arranged bump protection ring pad 321 at the both ends of connecting tube 32.While by
It is fixedly connected in cross bar 31 with two adjacent protective fence units, impact force can be passed to two adjacent protective fence units,
Make its common stress, prevents from causing protective fence unit to be knocked away since impact force is excessive, hurt the vehicle and pedestrian of surrounding.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
