Detailed description of the invention
Below in conjunction with accompanying drawing (Fig. 1-Fig. 3), the utility model is described.
Fig. 1 implements the double-deck guardrail facade structures of wave beams of the present utility model schematic diagram.Fig. 2 implements the double-deck guardrail plane structure of wave beams of the present utility model schematic diagram.Fig. 3 implements the double-deck guardrail section structure of wave beams of the present utility model schematic diagram.As Fig. 1, shown in Fig. 2 and Fig. 3, the double-deck guardrail of wave beams, comprise and be arranged in the guardrail end 16 at guardrail two ends (Fig. 1 and Fig. 2 have only represented right-hand member end, left end end does not draw, its structure is identical with right-hand member end) and guardrail between guardrail two ends middle part, described guardrail middle part comprises several guardrail middle part columns 18, each guardrail end 16 (for example comprises at least two guardrail end columns, guardrail end the first column 11 and guardrail end the second column 10), it is characterized in that, lower floor's wave beams 1 and upper waveform beam 2 are laid in same side at described several guardrail middle part columns 18, between wave beams and column, be provided with obstruction block 8, the same side of described at least two guardrail ends 16 columns is directly fixedly connected with lower floor's wave beams 1 and upper waveform beam 2, spacing between the top edge of described lower floor wave beams and the lower limb of described upper waveform beam is 1 ㎝～15 ㎝, spacing between lower limb and the ground of described lower floor wave beams is that 30 ㎝～44 ㎝ (are converted into Parameter H in engineering construction, the standard of individual layer corrugated beam barrier is H=60 ㎝, the span of center to center distance ground 3 height H of lower floor's wave beams 1, in this programme, be less than 60 ㎝).Each guardrail end 16 has three guardrail end columns (guardrail end the first column 11, guardrail end the second column 10 and guardrail end the 3rd column 9).Described three guardrail end columns connect as a whole, form rigidity anchored end.Described three guardrail end columns form anchor connection, described anchor connection adopts drag-line 12, described drag-line 12 forms oblique pull triangle by connecting three link positions, the 3rd link position 15 is positioned at the upper position on guardrail end the 3rd column 9 that end of guardrail starts at, the first link position 13 is positioned at the lower position on guardrail end the first column 11, and the second link position 14 is positioned at the lower position on guardrail end the second column 10.Described the 3rd link position 15 is between lower floor's wave beams 1 and upper waveform beam 2.Described lower floor wave beams 1 and upper waveform beam 2 all form two crests 6 along the vertical direction of wave beams, and middle is trough, and a upper crest 6 and a lower crest 6.The ground 3 of described lower floor wave beams 1 correspondence is provided with road kerb 4 (road kerb in figure has inclined-plane 7 in road kerb), and road kerb medial surface 5 is no more than the distance of crest 6 to column to the distance of column.Described obstruction block 8 connects column (by the column connection of boring a hole) by the first set bolt 19, connects wave beams by the second set bolt 21.On described lower floor wave beams 1 and upper waveform beam 2, be provided with splice bolt 20.Described guardrail end 16 has the end of guardrail 17 that steel plate coiling forms, and described end of guardrail has the arc surface that exceeds semicircle.
The effect of lower floor's wave beams 1 is mainly protection minibus, and its height H apart from ground 3 is the key parameter that affects minibus collision guardrail result, and the reasonable value of H should be the height of the minibus collision main force part of side front end far from ground.If H is excessive, after minibus collision, easily below lower floor's wave beams 1, pass guardrail; If H is too small, can make on the one hand the minibus collision main force part of side front end act between lower floor's wave beams 1 and upper waveform beam 2, cause minibus collision side front end to be stuck between lower floor's wave beams 1 and upper waveform beam 2, cause the resistance of stumbling; On the other hand, if guarantee lower floor's wave beams 1 and upper waveform beam 2 spacing are constant, upper waveform beam 2 highly also reduces with lower floor's wave beams 1, means that guardrail whole height reduces, and this can cause above upper waveform beam 2, running off guardrail after motor bus collision.
If road kerb 4 is set, must ensure that the inner surface 5 of road kerb 4 and the inner surface 6 of wave beams crest flush (inwardly exceeds in the middle of Ji Xiang road, but can be more near column, Ji Xiang moves outside road), otherwise can cause climbing along road kerb inclined-plane 7 in vehicle collision guardrail process, although may cross guardrail after vehicle climbs or not cross guardrail, while falling go back to ground 3 after climbing, affect vehicle run stability, cause overturning.
The necessary anchoring of guardrail end, the mode of anchoring is between end column 9,10 and 11, to connect (Fig. 1) as a whole and end column 9,10 and 11 by drag-line 12 obstruction block 8 (Fig. 2) is not set, and wave beams 1 and wave beams 2 are directly connected on column 9,10 and 11.Guardrail end anchoring is firmly conducive to prevent in vehicle collision process to cause guardrail lateral displacement excessive because end produces moderate finite deformation, causes that bad stumble resistance or the vehicle of even causing of Vehicle Driving Cycle attitude cross guardrail.As a whole by column 9,10 is connected with 11, can increase the rigidity of structure, form rigidity anchored end, remove the obstruction block 8 on column 9,10 and 11 simultaneously, be conducive to prevent, because the shear strain of obstruction block causes wave beams end, larger displacement occurs.
Indicate at this, above narration contributes to those skilled in the art to understand the invention, but and the protection domain of unrestricted the invention.Any do not depart from the invention flesh and blood to being equal to replacement, modifying and improve and/or delete numerous conforming to the principle of simplicity and the enforcement carried out of above narration, all fall into the protection domain of the invention.
