In general, a crosswalk is a road prepared by marking a crosswalk on a roadway so that a person can cross it horizontally. However, in the case of roads marked with crosswalks indicating crosswalks, the road height is the same as that of general roadways, so the vehicle speed reduction function cannot be provided, which always implies the safety risk of pedestrians crossing the crosswalk.

In order to solve this problem, the road surface of the crosswalk line is higher than the general roadway, that is, the jaw having a slope of the roadway section of the crosswalk line is implemented, thereby reducing the vehicle speed and the vehicle speed. At the same time, the hump type crosswalk is also provided, but since the jaw has such a slope is made of asphalt or cement, a new problem of having to reconstruct the whole when partial breakage occurs due to use has been derived.

In order to solve such a problem, the crosswalk is provided in the form of a deceleration jaw having a slope, but it has been solved by implementing the deceleration jaw having the slope as an assembled block.

1 to 3 is a view showing a conventional assembled crosswalk block pre-registered (Utility Model Registration No. 385871).

As shown, the conventional assembled crosswalk block is composed of a planar block portion 10, a curved block portion 20 and the anchor bolt 30, the first planar block portion 10 is formed in different side directions The first coupling protrusion 11 and the first coupling groove 12 are provided, and the curved block portion 20 is provided with the second coupling protrusion 21, the second coupling groove 22, and the second through hole 23. .

Due to this configuration, the second coupling protrusion 21 and the second coupling groove 22 are formed in the curved block portion 20 corresponding to the first coupling protrusion 11 and the first coupling groove 12 of the planar block portion 10. Are each male and female, and each of the male and female planar block portions 10 and the curved block portions 20 are placed on a roadway on which a crosswalk is to be placed, and then a second through hole 23 formed in the curved block portion 20 is formed. By bolting the road surface in the state in which the anchor bolt 30 is introduced through it, the flat block portion 10 and the curved block portion 20 coupled to the male and female are provided to be fixed on the road surface.

In addition, the first block penetrating through the first planar block portion 10, which is assembled to the center of each of the planar block portions 10 so that each of the planar block portion 10 and the curved block portion 20 fixed to the road surface more firmly fixed The hole 15 is formed so that it is also provided to be fixed to the road surface using the anchor bolt (30).

As such, the conventional assembled crosswalk block to be installed only needs to replace the corresponding block portions 10 and 20 where the breakage occurs when partial breakage occurs during use, thereby reducing maintenance costs and maintaining maintenance costs. It also provides an advantage over time.

However, the conventional assembled crosswalk block causes the following problems when the dynamic shock amount transmitted from the pedestrian in motion as well as the dynamic shock amount transmitted from the traveling vehicle.

In the case of a conventional assembled crosswalk block, the planar block portion 10 and the curved block portion 20 are transmitted from a vehicle in motion and a pedestrian in motion, since the flat block portion 10 and the curved block portion 20 are fixed on the road surface by the bolts of the anchor bolts 30. The amount of dynamic shock to be fixed to the planar block portion 10 and the curved block portion 20 is concentrated in the anchor bolt 30 which is an energy unstable.

Due to this, the anchor bolt 30 coupled vertically to the road surface is shaken from side to side due to the amount of dynamic shock continuously transmitted from all directions (front, rear, left and right), and if such a situation is repeated anchor bolts vertically coupled to the road surface The fall of the coupling force of the 30 causes a problem that the prefabricated crosswalk block itself is shaken.

Since this problem may act as a factor causing a safety accident to a driving vehicle, a problem of frequent maintenance is also derived.

Furthermore, each new block portion 10, 20 to be replaced for maintenance may be fixed with anchor bolts 30 at the same position as the through holes 15, 23 formed in the replaced block portions 10, 20. Can't. This is because the stator itself is impossible because the diameter of the through hole into which the anchor bolt 30 formed on the road surface is inserted is already widened by the dynamic impact amount, which corresponds to the previous through holes 15 and 23. .

However, since each of the block portions 10 and 20 is made of plastic and is usually manufactured by injection molding, when the position of the through holes 15 and 23 formed in each of the new block portions 10 and 20 to be replaced is changed, the mold The problem of having to replace itself is further derived. Here, since the price of the mold is high, ranging from tens of millions of won to hundreds of millions of won, it also leads to a huge replacement cost.
