Abstract
The utility model relates to a wave shaped joist steel safety guard clog proof block, and belongs to the road safety device, which is put forwards under the present condition that a wave shaped joist guard rail is adopted for the central partition of high way road in our country presently, and the strength of the wave shaped joist steel guard rail board is not utilized completely, normally a big vehicle out of control can not be stopped on passing through; a rectangular tube-shaped clog block with a large anti-rigidity performance is arranged between a vertical post of the wave shaped joist steel guard rail and the wave shaped joist steel guard rail board to transfer a crash force, so that the overall load resistance condition of the wave shaped joist steel guard rail can be improved, and a triangular corner-cutting is arranged at the lower end of the utility model; a space is reserved for the vertical rotation of the wave shaped joist steel guard rail board through the corner-cutting, the loading resistance condition of the wave shaped joist steel guard rail board is improved; when the vertical post of the wave shaped joist steel guard rail is overturned under an impact, the wave shaped joist steel guard rail board is basically in vertical manner to stop a vehicle. Computer simulation technology is adopted in the design of the utility model to conduct a comparison and optimization, and the utility model is proved by an actual vehicle crashing test, which is particularly used for a three-beam steel guardrail with big guard rail board width.
Description
Technical field
The utility model belongs to the road safety device, particularly a kind of being used for along the obstruction block of road extension or the continuity guardrail between the track.
Background technology
Corrugated beam steeled protection fence is a kind of guardrail form commonly used, and this guardrail has advantages such as good looking appearance, easy construction, has therefore obtained using on a large scale in highway in China.But in the use of reality, find, guardrail is being subjected to not preventing passing through of vehicle when errant vehicle impacts effectively, most applications is that to show as the guardrail local pressure bigger, fence upright lodging, guardrail board height reduce, thereby make vehicle press or climb over from guardrail, the intensity of this explanation corrugated beam steeled protection fence plate is not fully exerted.
The utility model content
The technical problems to be solved in the utility model is, at the deficiencies in the prior art, proposes a kind ofly can improve the whole stress-bearing capability of corrugated beam steeled protection fence, improves the technical scheme of the force-bearing situation of corrugated beam steeled protection fence plate.
The technical scheme that the utility model proposed is, on corrugated beam steeled protection fence, adopt a kind of obstruction block, it is characterized in that this obstruction block is the steel tubular, between fence upright and corrugated beam steeled protection fence plate, adopt connector to be connected with fence upright, corrugated beam steeled protection fence plate respectively.The face that joins from obstruction block and corrugated beam steeled protection fence plate, to the lower surface of obstruction block, along obstruction block length direction, this angle, 1 base of pruning, form 1 triangle top rake, this top rake hypotenuse and obstruction block lower surface angle are good with 40～50 degree, the upper edge of this top rake on obstruction block and corrugated beam steeled protection fence plate abutted surface is positioned at the lower wave trough place of the corrugated beam steeled protection fence plate that joins with obstruction block.Obstruction block can be selected the rectangular cylinder shape for use, its cross section is a rectangle, this rectangle tubular obstruction block matches with H column type fence upright, its length promptly along the length of the direction between column and the corrugated sheet greater than 250 millimeters, promptly length is greater than 120 millimeters longitudinally along guardrail for width, and the height of obstruction block is corresponding with the height of corrugated beam steeled protection fence plate.
The utility model beneficial effect compared with prior art is the crashproof ability that it has improved corrugated beam steeled protection fence effectively, by adopting the big obstruction block of rigidity, transmit impact force, improve the whole stress-bearing capability of guardrail, and reserve the space for the vertical rotation of guardrail board, when fence upright is subjected to impacting when toppling by the oblique angle of cutting out in the obstruction block bottom, it is vertical substantially that guardrail board can keep, give full play to the guardrail board barrier effect, block vehicle, guarantee traffic safety.Design of the present utility model has adopted computer simulation technique to be optimized than choosing, and has passed through the real vehicle collision test checking.The utility model is applicable to corrugated beam steeled protection fence, is particularly useful for three bigger corrugated beam steeled protection fences of guardrail board width.

Fig. 5 is Fig. 2 A-A view.
The specific embodiment
As shown in the figure, obstruction block 3 is steel tubular rectangle between H shape fence upright 1 and corrugated beam steeled protection fence plate 2, and the angle of pruning, its lower end forms a triangle top rake 4, and the top rake upper edge is positioned at lower wave trough 6 places of three ripple beam slabs 2.The height of triangle top rake is 180 millimeters, and the base is 150 millimeters, and hypotenuse and obstruction block lower surface angle are thought 50 degree.5 millimeters of obstruction block 3 wall thickness, high 450 millimeters, wide 120 millimeters, long 250 millimeters.Obstruction block 3 connects by connecting hole 7 with the bolt that adopts 4 diameters more than or equal to 14 millimeters being connected of column 1.Obstruction block 3 connects by connecting hole 8 with the bolt that adopts 1 diameter more than or equal to 14 millimeters being connected of corrugated beam steeled protection fence plate 2, and link position is trough 5 places on three ripple beam slabs 2.
When obstruction block is applied to the two plate guardrail of H shape column two ripples, get 4 millimeters of obstruction block wall thickness, high 310 millimeters, wide 150 millimeters, long 250 millimeters, 100 millimeters on the base of triangle top rake, angle 45 degree of top rake hypotenuse and obstruction block lower surface, the top rake upper edge is positioned at the lower wave trough place of two ripple beam slabs.
Claims (5)
