Description
Technical field
The present invention relates to highway safety facility field, and in particular to a kind of three ripples wave-shaped beam guardrail board.
Background technology
Existing three ripples wave-shaped beam guardrail board two ends splicing screw hole design is the splicing screw of the centre-to-centre spacing such as two groups of 16-24*30.It has the disadvantage：Splice screw 1（10-24*30）With splicing screw 2（10-24*30）In same cross section（I-I）, each screw centre-to-centre spacing is equal, make two corresponding bolts by it is too near, cause splice bolt install and anti-theft nut rundown process in disturb each other, inconvenience is installed and tightened, and speed is slow, and efficiency is low, and intensity is big.Installation quality is affected.
The content of the invention
To solve the above problems, the present invention provides a kind of three ripples wave-shaped beam guardrail board, a kind of three ripple wave-shaped beam guardrail boards, it is raised that the corrugated guardrail plate includes first, second raised and the 3rd projection, described first raised both sides are from top to bottom distributed the first screw, second screw, described second raised both sides are from top to bottom distributed the 3rd screw, 4th screw, described 3rd raised both sides are from top to bottom distributed the 5th screw, 6th screw, first screw, second screw, 3rd screw, 4th screw, 5th screw and the symmetrical distribution of the 6th screw have two rows and located at corrugated guardrail plate two ends.
Described two first screws or two the 3rd screws or the 5th screw are D to the distance of axis, and described two second screws or two the 4th screws or the 6th screw are L to the distance of axis, and the absolute value of the difference of the D and L is 5 ~ 20
mm。
The absolute value of the difference of the D and L is less than the first screw or the second screw or the 3rd screw or the 4th screw or the 5th screw or the 6th screw to the distance at breast board edge.
The described first raised groove being evenly distributed with the second raised middle groove in the middle of four the 7th screws, second projection and the 3rd projection is evenly distributed four the 8th screws.
First screw, the second screw, the 3rd screw, the 4th screw, the 5th screw, the 6th screw, the 7th screw and the 8th screw hole dimensions are 24*30
mm。
Two corresponding splicing screws of this device of the invention are in staggered distribution, pitch-row increase, with advantages below：One, which is easy for the installation of splice bolt, antitheft splicing nut, tightens；Two be that can accelerate to install, tighten speed, reduces labo r usage, cost-effective, so that larger raising work efficiency；Three be to reduce the labor intensity of operator；Four are easy in three ripple wave-shaped beam guardrail board assembling process carrying out do mechanization operation and flow operations；Five be the cross-sectional area enlarged relative at screw, adds the intensity of three ripple wave-shaped beam guardrail boards.
Brief description of the drawings

1
As shown in Figure 1, a kind of three ripple wave-shaped beam guardrail boards, the corrugated guardrail plate includes first the 1, second projection 2 of projection and the 3rd projection 3, first raised 1 both sides are from top to bottom distributed the first screw 4, the second screw 5, second raised 2 both sides are from top to bottom distributed the 3rd screw 6, the 4th screw 7,3rd raised 3 both sides are from top to bottom distributed the 5th screw 8, the 6th screw 9, and first screw 4, the second screw 5, the 3rd screw 6, the 4th screw 7, the 5th screw 8 and the symmetrical distribution of the 6th screw 9 have two rows and located at corrugated guardrail plate two ends.
Described two first screws 4 or two the 3rd screws 6 or the 5th screw 8 are D to the distance of axis, and described two second screws 5 or two the 4th screws 7 or the 6th screw 9 are L to the distance of axis, and the absolute value of the difference of the D and L is 5 ~ 20
mm。
The absolute value of the difference of the D and L is less than the first screw 4 or the second screw 5 or the 3rd screw 6 or the 4th screw 7 or the 5th screw 8 or the 6th screw 9 arrives the distance at breast board edge.
The groove that groove in the middle of the projection 2 of first projection 1 and second is evenly distributed in the middle of four the 7th screws 10, the projection 3 of the second projection 2 and the 3rd is evenly distributed four the 8th screws 11.
