Description

Road junction marking post and warning pile

Technical Field

The utility model belongs to highway traffic safety facility field, concretely relates to road junction marker post and stake of warning.

Background

The existing highway crossing marking post (commonly called crossing post) and the warning post are generally PVC pipes, a steel bar framework is arranged inside the existing highway crossing marking post and concrete is poured, a reflective film is pasted outside the existing highway crossing marking post, and the existing highway crossing marking post and the warning post are embedded in concrete foundations on the roadside. (the detailed structure is shown in appendix E of the road safety and life protection engineering implementation technical guideline), the road junction marking post and the warning post adopting the structure have the following defects:

1. the whole body is easy to be damaged under the condition of vehicle collision or scratch, thereby losing the warning function.

2. The bicycle is not easy to damage after being impacted or scratched by a bicycle or other non-motor vehicles, but the bicycle or other non-motor vehicles and drivers are easy to be injured to a certain extent due to the higher rigidity of the cylinder body.

3. In winter, the interior of the cylinder is frozen and swelled after snow water is immersed, so that the outer part of the cylinder is damaged.

For example, the patent technology of the publication number CN206379118U entitled "PVC pipe concrete marking pile for pipeline protection in construction site" disclosed by the chinese patent office on 04/08/2017 includes a PVC pipe, and concrete is poured into the PVC pipe to form a concrete cylindrical pile. The marker post has the above-mentioned 3 drawbacks.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a road junction post and stake of warning, it adopts the good cavity PE cylinder of toughness to replace PVC concrete pile, and is not fragile after the collision, easily recovers, and is little to non-motor vehicles such as bicycles and driver's injury, can not damage because of frostbite.

The utility model provides a scheme that its technical problem adopted is:

the utility model provides a road junction marker post and stake of warning, a serial communication port, including hollow PE cylinder and sleeve, the sleeve is open with the equal upper end of PE cylinder, and telescopic inner wall is equipped with the internal thread, and the lower part of PE cylinder outer wall is equipped with the external screw thread that matches with the sleeve internal thread, the lower part of PE cylinder be located the sleeve and with sleeve threaded connection, inwards protruding have the strip of turning round of two symmetries on the inner wall of PE cylinder lower part, the upper portion of PE cylinder outer wall is equipped with the reflective membrane.

When the utility model is used, the sleeve is pre-embedded into the concrete foundation under the road surface for fixation, the bottom of the PE cylinder is vertically installed into the sleeve through the screw thread, and the reflective film on the PE cylinder and the upper part of the PE cylinder plays the role of safety reminding and warning for pedestrians or drivers; because the improvement of material and the change of structure, the toughness of cylinder promotes greatly, the PE cylinder still can the reconversion after scraping and colliding many times, just can take place to damage when suffering many times serious collision, after the PE cylinder of device is hit to break and damages, remaining PE cylinder is twisted out from the sleeve to the accessible specialized tool, specialized tool is the I-shaped spanner, two recesses of the I-shaped spanner are aimed at behind two torsion bars of PE cylinder and are blocked, rotate the spanner hard and can drive the PE cylinder and rotate and take out it, removable new PE cylinder and muffjoint afterwards.

The utility model discloses a high tenacity PE pipe is preferred to adopt to the PE cylinder.

The concrete foundation for fixing the sleeve is preferably made of C25 concrete.

Furthermore, the upper end of the PE cylinder is provided with a cap, the cap comprises an upper cap brim and a lower cap barrel, the diameter of the cap brim is larger than the inner diameter of the PE cylinder, and the outer diameter of the cap barrel is matched with the inner diameter of the PE cylinder.

The utility model discloses adopt grafting or threaded connection between the cap section of thick bamboo of block and the PE main part.

The utility model discloses a block that sets up can prevent in foreign matters such as sleet, water, rubbish get into the PE cylinder, avoid in winter sleet get into the PE cylinder that frost heaving arouses the PE cylinder break.

Further, be equipped with two on the sleeve lateral wall of PE cylinder below not coplanar and radial vertically preformed hole, two preformed holes run through the barrel respectively, and two twisted steel pass two preformed holes respectively and are located the sleeve to form the cross jointly.

The utility model discloses a twisted steel is pre-buried in the concrete foundation, plays the effect of theftproof, preventing extracting to the sleeve.

Furthermore, the reflective film comprises a red reflective film and a white reflective film which are sequentially arranged at intervals.

When the reflective films of the device are the red reflective film and the white reflective film, the device is used as a road junction marker post to remind a main line vehicle of improving alertness and prevent accidents caused by sudden appearance of small branch road vehicles.

Furthermore, the reflective film comprises a yellow reflective film and a black reflective film which are sequentially arranged at intervals.

When the reflective membrane of this device is yellow reflective membrane and black membrane, this device is used as the stake of warning for there is dangerous highway section to the roadside to warn the induction.

The beneficial effects of the utility model are that:

1. through the improvement of material and the change of structure, the cylinder toughness of crossing post and the stake of warning promotes greatly, the PE cylinder still can the reconversion after scraping and colliding many times (the collision needs the manual work to right when very serious), only need to paste the membrane again to damaged part reflective membrane just can come into operation again, current crossing post has been solved comprehensively, the fragile shortcoming that the stake of warning exists, greatly reduced the maintenance cost of crossing post and the stake of warning.

The PE cylinder adopts hollow structure, and is with low costs, toughness is good, and PE cylinder upper end sets up the block simultaneously and prevents that foreign matters such as sleet water and rubbish from getting into, compares PVC concrete structure's way mouth mark post and warning stake, has avoided freezing and expanding the cylinder damage that causes after the sleet gets into winter because of the sleet.

The price of the PE material is slightly higher than that of the PVC material, but the consumption of concrete and steel bars is reduced, so that the whole cost is equivalent to that of the original structure and the prepared crossing mark post and warning pile, and the PVC material is very favorable for popularization and application.

4. The detachable structure of the sleeve and the PE cylinder ensures that the PE cylinder is convenient to replace when damaged.

5. Through the improvement of materials and the change of the structure, the post bodies of the crossing marking post and the warning post are elastically deformed due to the lower rigidity of the post bodies after being impacted or scratched by non-motor vehicles such as bicycles and the like, so that the non-motor vehicles such as bicycles and the like and drivers can be well protected.
