Two ripples waveform guardrail plate include that first arch and second are protruding, first protruding both sides from top to bottom distribute first screw, second screw, the protruding both sides of second from top to bottom distribute third screw, fourth screw, about first screw, second screw, third screw and fourth screw altogether the symmetric distribution have two rows and locate the waveform guardrail plate both ends, groove in the middle of first arch and the second arch is equipped with the 5th screw just the 5th screw is located the axis of two first screws or two second screws or two third screws or two fourth screws. The utility model discloses installation, screw -Tightening speed can be accelerated to be convenient for the screwing up of installation, theftproof concatenation nut of splice bolt, reduce artifical quantity, practice thrift the cost to great improvement work efficiency rate.
Description
Technical field
This utility model relates to highway safety facility field, is specifically related to a kind of two wave-wave ellbeam guardrail board.
Background technology
Existing wave-shaped beam guardrail board (two ripples) two ends splicing screw hole design is the splicing screw of the centre-to-centre spacing such as two groups of 4-20*30.Its shortcoming is: splicing screw 1(4-20*30) and splicing screw 2(4-20*30) in same cross section (I-I), each screw centre-to-centre spacing is equal, corresponding two bolt is made to lean on the nearest, cause splice bolt to install and anti-theft nut rundown process is disturbed each other, inconvenience is installed and is tightened, and speed is slow, efficiency is low.The most also have an impact on installation quality.
Summary of the invention
For solving the problems referred to above, this utility model provides a kind of two wave-wave ellbeam guardrail board, described two waveform guardrail board include first protruding and the second projection, described first protruding both sides are from top to bottom distributed the first screw, the second screw, described second protruding both sides are from top to bottom distributed the 3rd screw, the 4th screw, are symmetrically distributed with two rows altogether and are located at corrugated guardrail plate two ends about described first screw, the second screw, the 3rd screw and the 4th screw.
Said two the first screw or two the 3rd screws are D to the distance of axis, and the distance of said two the second screw or two the 4th screws to axis is L, and the absolute value of the difference of described D Yu L is 5 ~ 20mm.
The absolute value of the difference of described D Yu L is less than the first screw or the second screw or the 3rd screw or the 4th screw distance to wave-shaped beam guardrail board edge.
Described first protruding and that the second projection is middle groove is provided with the 5th screw and described 5th screw is positioned on the axis of two the first screws or two the second screws or two the 3rd screws or two the 4th screws.
Described 5th screw hole dimensions is 20*30mm.
Described first screw, the second screw, the 3rd screw and the 4th screw hole dimensions are 20*30mm.
This device of this utility model corresponding two splicing screws are in staggered distribution, relative opening away from increase, have the advantage that one is easy for the installation of splice bolt, the tightening of antitheft splicing nut；Two is can to accelerate to install, tighten speed, reduces labo r usage, cost-effective, thus bigger raising work efficiency；Three is the labor intensity reducing operator；Four are easy for implementation do mechanization operation and flow operations during two wave-wave ellbeam guardrail board assemblings；Five is the cross-sectional area enlarged relative at screw, adds the intensity of two wave-wave ellbeam guardrail board.
Accompanying drawing explanation
Fig. 1 is this utility model two wave-wave ellbeam guardrail board side schematic view；
Fig. 2 is this utility model two wave-wave ellbeam guardrail board structural representation；
Wherein: the first projection 1, the second projection 2, the first screw 3, the second screw 4, the 3rd screw 5, the 4th screw 6, the 5th screw 7.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, a kind of two wave-wave ellbeam guardrail board, described corrugated guardrail plate includes the first protruding 1 and second projection 2, it is characterized in that: described first protruding 1 both sides are from top to bottom distributed first screw the 3, second screw 4, described second protruding 1 both sides are from top to bottom distributed the 3rd screw the 5, the 4th screw 6, and described first screw the 3, second screw the 4, the 3rd screw 5 and the 4th screw about 6 are symmetrically distributed with two rows altogether and are located at corrugated guardrail plate two ends.
Said two the first screw 3 or two the 3rd screws 5 are D to the distance of axis, and the distance of said two the second screw 4 or two the 4th screws 6 to axis is L, and the absolute value of the difference of described D Yu L is 5 ~ 20mm.
The absolute value of the difference of described D Yu L is less than the first screw 3 or the second screw 4 or the 3rd screw 5 or the 4th screw 6 distance to wave-shaped beam guardrail board edge.
Groove in the middle of described first protruding 1 and second protruding 2 is provided with the 5th screw 7 and described 5th screw 7 is positioned on the axis of two the first screws 3 or two the second screws 4 or two the 3rd screws 5 or two the 4th screws 6.
Described 5th screw 7 a size of 20*30mm.
Described first screw the 3, second screw the 4, the 3rd screw 5 and the 4th screw 6 a size of 20*30mm.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as the restriction for the present invention, and the embodiment in the application and the feature in embodiment, can mutual combination in any in the case of not conflicting.The technical scheme that protection scope of the present invention should be recorded with claim, is protection domain including the equivalents of technical characteristic in the technical scheme that claim is recorded.Equivalent the most in this range is improved, also within protection scope of the present invention.
