Abstract
The utility model belongs to the technical field of guardrail tools, and particularly relates to an inner fin of a highway guardrail. The inner fin of the highway guardrail is characterized in that a fin body is included, the fin body gradually shrinks from the head portion to the tail portion, the fin body comprises an outer shell and a cavity, a plurality of inner bars are arranged in the cavity, the inner bars are of an S shape, and the R angle of the tail portion of the fin body is 0.5-0.7 degree. The inner fin of the highway guardrail can be well matched with an outer fin to absorb outside impacting force and to bear high-strength impacting, thereby improving the safety performance of the entire guardrail.
Description
Technical field
The utility model belongs to guardrail apparatus technical field, relates in particular to a kind of interior wing of high speed guardrail.
Background technology
Guardrail is mainly used in the occasions such as highway, factory, workshop, warehouse, parking lot, commercial area, public place protection and the protection to equipment and facilities.Guardrail is visible everywhere in our life.Guardrail is all generally to be used in conjunction with each other with column.The column of guardrail is fixed by expansion bolt and ground.Usually be installed on as the road both sides production equipment periphery, building ，Men both sides, corner and goods edge of table edge etc.And the material that general guardrail adopts is all steel.There is this defect in this type of guardrail, and while particularly being applied on speedway, its defect is more obvious.The speed of a motor vehicle due to automobile on speedway is very fast, so, when having an accident, the shock dynamics of automobile and guardrail is larger, so common guardrail is very easy to be damaged, and the shock dynamics can't be reduced, thereby makes guardrail not have the effect of its protection.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of interior wing of high speed guardrail is provided, and its technical scheme is as follows:
A kind of interior wing of high speed guardrail, it is characterized in that, the interior wing of described high speed guardrail comprises the wing body, described wing body is shunk gradually by head to afterbody, described wing body comprises shell and cavity, be provided with some interior muscle in described cavity, described interior muscle is S shape, and the R angle of the afterbody of described wing body is the 0.5-0.7 degree.
Optimal way is that described shell is extruded and processed by the toughening modifying formula by the pvc resin.
Optimal way is, the thickness of described shell is 2.5-3.0mm, and the thickness of described interior muscle is 0.8-1.0mm.
The interior wing of the high speed guardrail that the utility model provides, when in use, be arranged on whole interior wing the inboard of outer wing, makes interior wing closely be connected with outer wing.And described wing body is shunk gradually by head to afterbody, can be so that the convenient inboard that is arranged at outer wing of interior wing makes connection between the two more firm and tight.Described wing body comprises shell and cavity, can be so that whole interior wing has impact-absorbing preferably by cavity.Be provided with some interior muscle in described cavity, described interior muscle is S shape, can be so that interior wing, in impact-absorbing, has the impact property of good bearing high strength by muscle in S shape.The R angle of the afterbody of described wing body is the 0.5-0.7 degree, and the R angle is exactly fillet, and it is in order better to coordinate outer wing, to make the connection between interior wing and outer wing tightr, thereby make, having impact-absorbing power preferably.
Shell described in the utility model is extruded and is processed by the toughening modifying formula by the pvc resin.Shell after the modification of pvc resin toughening has toughness preferably, can when receiving impact, have impact property and the impact-absorbing power performance of bearing high strength preferably.
The thickness of shell described in the utility model is 2.5-3.0mm, and the thickness of described interior muscle is 0.8-1.0mm.Shell under this size and interior muscle thickness, also make whole interior wing more light in the time of the impact property of the bearing high strength that can better keep it to have, and is convenient to install and save material.
The utility model can be good at coordinating outer wing to absorbing extraneous impact force and the impact property of bearing high strength, improves the security performance of whole guardrail.
The accompanying drawing explanation
Fig. 1 schematic diagram of the present utility model.
The specific embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of interior wing of high speed guardrail, it is characterized in that, the interior wing of described high speed guardrail comprises wing body 1, described wing body 1 is shunk gradually by head to afterbody, described wing body 1 comprises shell 2 and cavity 3, be provided with some interior muscle 4 in described cavity 3, described interior muscle 4 is S shape, and the R angle 5 of the afterbody of described wing body 1 is the 0.5-0.7 degree.
Optimal way is that described shell is extruded and processed by the toughening modifying formula by the pvc resin.
Optimal way is, the thickness of described shell is 2.5-3.0mm, and the thickness of described interior muscle is 0.8-1.0mm.
The interior wing of the high speed guardrail that the utility model provides, when in use, be arranged on whole interior wing the inboard of outer wing, makes interior wing closely be connected with outer wing.And described wing body is shunk gradually by head to afterbody, can be so that the convenient inboard that is arranged at outer wing of interior wing makes connection between the two more firm and tight.Described wing body comprises shell and cavity, can be so that whole interior wing has impact-absorbing preferably by cavity.Be provided with some interior muscle in described cavity, described interior muscle is S shape, can be so that interior wing, in impact-absorbing, has the impact property of good bearing high strength by muscle in S shape.The R angle of the afterbody of described wing body is the 0.5-0.7 degree, and the R angle is exactly fillet, and it is in order better to coordinate outer wing, to make the connection between interior wing and outer wing tightr, thereby make, having impact-absorbing power preferably.
