Description
Technical field
The present invention relates to a kind of road signs, be specifically related to a kind of disintegration energy dissipating sign and method for using thereof.
Background technology
Traffic sign is the road equipment with literal or symbol transmission guiding, restriction, warning or indication information, is to implement traffic administration and the important measures that guarantee traffic safety.
But; Because traffic sign need be arranged on trackside, therefore, in the above-mentioned various effects of performance; Also have following problem: vehicle is when going out main road; Usually can bump against the traffic sign column, because the bigger anti-force of traffic sign column tends to vehicle is caused bigger injury with fast speeds.
Summary of the invention
To the defective that prior art exists, the present invention provides a kind of disintegration energy dissipating sign and method for using thereof, and after vehicle bumped against the sign column, the sign column can lodge along vehicle heading, thereby has alleviated the infringement that the sign column causes vehicle.
The technical scheme that the present invention adopts is following:
The present invention provides a kind of disintegration energy dissipating sign, comprising: end flange, upper flange plate, sign column, lower pillar stand and concrete foundation; Said lower pillar stand is embedded in the said concrete foundation; Flange of the said end is fixedly connected with said lower pillar stand; Said upper flange plate is fixedly connected with said sign column; Flange of the said end is connected through rotating shaft with an end of said upper flange plate, and flange of the said end is fixedly connected through splice bolt with the other end of said upper flange plate.
Preferably, also comprise: fixed hook; Said fixed hook comprises arc part and the afterbody integrally formed with said arc part; Said afterbody is fixedly connected with flange of the said end, and said arc part is connected with said rotating shaft hook.
Preferably, also comprise: ribs; One end of said ribs is fixedly connected with said upper flange plate, and the other end of said ribs is fixedly connected with said sign column.
Preferably, the length of the end flange axis hole at said rotating shaft place is greater than height.
Preferably, the screw that is positioned at said upper flange plate at said splice bolt place is last screw, and the screw that is positioned at flange of the said end at said splice bolt place is following screw; Said upward screw is the open-type screw.
The present invention also provides a kind of method for using of the energy dissipating sign that disintegrates, and may further comprise the steps:
When said sign column was clashed into, the flange axis hole moved forward along the said end for said upper flange plate and said rotating shaft, makes said upper flange plate break away from said splice bolt; Then, under thrust, the said rotating shaft in said sign column edge is rotated and is lodged.
Preferably, in said upper flange plate and said rotating shaft along when the flange axis hole moves forward at the said end, stretching said fixed hook.
Beneficial effect of the present invention is following:
Disintegration energy dissipating sign provided by the invention adopts rotating shaft and splice bolt to bear the moment of flexure that external force causes jointly, under Vehicular impact; Because thrust, the sign column follows the slippage of car direction, and splice bolt comes off; Thereby the sign column is rotated through rotating shaft; Follow the lodging of car direction, therefore, reduced the infringement that the sign column possibly cause the vehicle reaction force.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated:
As depicted in figs. 1 and 2, the present invention provides a kind of disintegration energy dissipating sign, comprising: end flange, upper flange plate, sign column, lower pillar stand and concrete foundation; Said lower pillar stand is embedded in the said concrete foundation; Flange of the said end is fixedly connected with said lower pillar stand; Said upper flange plate is fixedly connected with said sign column; Flange of the said end is connected through rotating shaft with an end of said upper flange plate, and flange of the said end is fixedly connected through splice bolt with the other end of said upper flange plate.Wherein, the upper flange plate structure is shown in Fig. 3-5, and end flange plate structure is shown in Fig. 6-8, and upper flange plate and end flange assembling back structure also comprise: fixed hook and ribs shown in Figure 12-13; Shown in Fig. 9-11, said fixed hook comprises arc part and the afterbody integrally formed with said arc part; Said afterbody is fixedly connected with flange of the said end, and said arc part is connected with said rotating shaft hook.The purpose that installs and fixes crotch is: when disintegration energy dissipating sign is in normal condition, through the fixed hook fixed rotating shaft, thereby guarantee that rotating shaft is not shifted; And when disintegration energy dissipating sign was clashed into by the impact force of vehicle, fixed hook can be opened by bump.One end of said ribs is fixedly connected with said upper flange plate, and the other end of said ribs is fixedly connected with said sign column.The length of the end flange axis hole at said rotating shaft place is greater than height.Shown in figure 13; The length L of end flange axis hole is greater than height W; Thereby guarantee that the flange axis hole moves forward the end of along in rotating shaft when the sign column receives thrust, and the distance that can move should be greater than splice bolt from the come off displacement of needs of upper flange plate.The screw that is positioned at said upper flange plate at said splice bolt place is last screw, and the screw that is positioned at flange of the said end at said splice bolt place is following screw; The said screw of going up is the open-type screw, and screw becomes greatly gradually, and such structure design is in order to satisfy under thrust, and upper flange plate can level move forward, and the disengaging splice bolt.
The method for using of disintegration energy dissipating sign provided by the invention may further comprise the steps:
When said sign column is clashed into; The flange axis hole moves forward along the said end for said upper flange plate and said rotating shaft, and then stretching said fixed hook, and fixed hook no longer countershaft plays fixation; And; Along with upper flange plate moves horizontally forward, upper flange plate breaks away from splice bolt, and splice bolt is also no longer folded fixation to upper flange; Then, under thrust, the said rotating shaft in sign column edge is rotated and is lodged.
Need to prove that the present invention does not limit the size of end flange, upper flange plate, rotating shaft, splice bolt, ribs, sign column, lower pillar stand, concrete foundation and fixed hook, can confirm according to the stressed size of sign column is concrete.
In sum, disintegration energy dissipating sign provided by the invention adopts rotating shaft and splice bolt to bear the moment of flexure that external force causes jointly; Under Vehicular impact, because thrust, the sign column follows the slippage of car direction; Splice bolt comes off, thereby the sign column is rotated through rotating shaft, follows the lodging of car direction; Therefore, reduced the infringement that the sign column possibly cause the vehicle reaction force.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be looked protection scope of the present invention.
