Abstract
The utility model provides a road safety guard bar, it includes stand, end wave form roof beam and interlude wave form roof beam, end wave form roof beam is in the same place with the bolted connection that interlude wave form roof beam passes through on the stand. The utility model discloses guardrail end wave form roof beam and stand junction except that the bolt hole of boxing out, still are provided with the round hole that a series of apertures slightly are less than the bolt hole, and after vehicle emergence accident, the direction that serial round hole can be followed to end wave form roof beam takes place the displacement for the impact of buffering accident vehicle, reduction accident degree.
Description
Technical field
The utility model belongs to highway construction technical field, is specifically related to a kind of road safety guard.
Background technology
Guardrail is the common facility of one for guarantee driving safety in highway engineering, especially expressway works, mainly contains column, wave beams composition, is connected and is jointly fixed on column before and after wave beams.Guardrail plays significance for protection people's property and life security.
General, be connected before and after guardrail and lay continuously along both sides of highway, have interruption when meeting intersection, behind intersection, again lay guardrail.At present, the Guardrail design of crossing is consistent with the Guardrail design of successive passage, is all that wave beams is bolted on column.In fact, crossing's vehicle is various, road conditions are complicated, and the accident that the direction that vehicle is parallel to guardrail trend knocks guardrail also happens occasionally, if the termination guardrail of crossing allows the displacement along guardrail trend occurs, then can alleviate accident casualty degree.
Summary of the invention
The utility model, for this problem, proposes a kind of road safety guard, it solves the problems referred to above.
The technical scheme that the utility model adopts is as follows:
A kind of road safety guard, it comprises column, termination wave beams and interlude wave beams, and termination wave beams and interlude wave beams are by being bolted together on column.
Wave beams one end, termination bends to arc; The junction of termination wave beams and column, except boxing out except bolt hole, is also provided with the circular hole that some diameters are less than bolt hole.
Compared with prior art, the utility model has the advantage of:
The utility model end of guardrail wave beams and column junction, except boxing out except bolt hole, also be provided with the circular hole that a series of aperture is slightly less than bolt hole, after vehicle has an accident, termination wave beams can be subjected to displacement along the direction of serial circular hole, for cushioning the percussion of accident vehicle, reduction accident degree.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of road safety guard of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of road safety guard, as shown in Figure 1, it comprises column 1, termination wave beams 2 and interlude wave beams 3, and termination wave beams 2 and interlude wave beams 3 are linked together by the bolt 4 on column 1.
Termination wave beams 2 one end bends to arc; Termination wave beams 2 and the junction of column, except boxing out except bolt hole, be also provided with the circular hole 5 that some diameters are less than bolt hole.
Embodiment:
In the maintenance works of certain mountain highway crossover location, former guardrail is replaced by the safety barrier that the utility model relates to, embodiment is as follows.
A kind of road safety guard, comprises column 1, termination wave beams 2 and interlude wave beams 3.Termination wave beams 2 and interlude wave beams 3 are linked together by the bolt 4 on column 1.Termination wave beams 2 one end bends to arc, the percussion of available buffer accident vehicle.The place that termination wave beams 2 is connected with column, except boxing out except bolt hole, be also provided with the circular hole 5 that a series of aperture is slightly less than bolt hole, after vehicle has an accident, termination wave beams 2 can be subjected to displacement along the direction of serial circular hole 5, for cushioning the percussion of accident vehicle.
First be about 40cm place in the original position of installing apart from guardrail and column 1 is installed.Then get the long conventional guardrail wave beams manufacturing terminal bow wave ellbeam 2 of 2.4m, first its one end is bent to the arc that diameter is about 30cm, radian about 270 degree, punch apart from other end 60cm place according to the position of bolt on column 1, two rows, connect interlude wave beams 2 for bolt by each two.
Then, between the bolt hole of left and right, make a call to two row's diameters compared with the hole of the little 2mm of bolt hole, often arrange 2.Make a call to the hole of two row's diameters compared with the little 2mm of bolt hole on the right side of right side bolt hole afterwards, often arrange 4.Interlude wave beams 2 adopts conventional guardrail wave beams.
Finally, use bolt to be fixed on column by termination wave beams 2 and interlude wave beams 3, namely complete installation.
In order to verify the degree of reliability of the safety barrier in the present embodiment, adopt quiet ultimate tensile strength and shock resistance of drawing load, the general guardrail of dynamic impulsion load comparative analysis and safety guardrail.Quietly draw in experiment, interlude wave beams vertically fixed, termination with bolts wave beams, adopt MTS810 downwards stretching termination wave beams until drawing crack, determination limit tensile strength, average is removed in three groups of experiments; In dynamic impulsion loading test, termination wave beams, interlude wave beams are from left to right placed in impact test groove with this level, the two uses bolt to connect, and then uses II type impact block to apply the impact load of 100kg, 80km/h from left side level, measures the remaining kinetic energy of impact block.
Result of the test is as shown in the table:
Experimental result
From experimental result, ultimate tensile strength and the general corrugated beam barrier of safety guardrail are roughly the same.But the effect of dampening shock loads significantly promotes, the cushioning effect of the safety barrier in the present embodiment improves about 40.1%, that is, accident degree can be reduced about 40%.
Above-mentioned detailed description of the invention is a preferred embodiment of the present utility model; be not for limiting enforcement of the present utility model and right; all equivalences made according to the content described in the utility model patent protection scope change and modify, and all should be included in the utility model patent claim.
