Description

[Technical field]

[0001] The present invention relates to a pavement forming member for forming a pavement. [Background technology]

[0002] There is a technology that involves pouring a paving material such as asphalt or concrete, laying a paving forming member with a mesh pattern made of wire material or the like on the paving material before it has completely hardened, pressing the paving forming member from above with a roller or the like, and separating the paving forming member from the paving material before it has completely hardened, thereby forming an uneven pattern on the surface of the pavement of roads, sidewalks, etc., thereby improving the aesthetics / landscape of the pavement. A method is also known in which a road surface covering material decorative sheet with an uneven pattern is attached to a road surface covering material to form a pattern (Patent Document 1).

[0003] [Patent Document 1] JP 2019-173311 A Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, asphalt and other pavements have poor drainage, and water inundation and puddles caused by rainfall are problems. However, an uneven surface pattern alone is not enough to prevent water inundation or puddles. Although an uneven surface pattern can improve drainage to some extent, it cannot be expected to prevent water inundation or puddles, so separate facilities such as drainage ditches are essential. [Means for solving the problem]

[0005] In this application: A pavement forming member for forming a pavement, A paving member is disclosed having a substrate and a plurality of protrusions formed on the substrate. [Brief description of the drawings]

[0006] [Figure 1] FIG. 1 shows a plan view of a pavement forming member 1 according to an embodiment of the present invention. [Diagram 2] FIG. 1 shows a perspective view of a pavement forming member 1. [Diagram 3] 1 shows a pavement forming method using the pavement forming member 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] 1 and 2 show a pavement forming member 1 according to one embodiment of the present invention. The pavement forming member 1 has a base material 10 and a protruding portion 20. The base material 10 can form unevenness such as a brick pattern or a geometric pattern on the pavement surface. As shown in the figure, the base material 10 can have a pattern such as a mesh. The protruding portions 20 can be formed at multiple locations on the base material 10. From the viewpoint of strength, it is preferable to provide the protruding portions 20 at the intersections of the mesh-shaped base material 10. The base material 10 and the protruding portions 20 are preferably made of a metal such as iron, but may be made of other materials. The base material 10 and the protruding portions 20 are preferably formed by integral molding, but may be formed by other methods.

[0008] FIG. 3 shows a pavement forming method according to one embodiment using the pavement forming member 1. As shown in FIG. 3(a), a pavement material 3 such as asphalt or concrete is poured onto a roadbed 2 formed of crushed stone or the like, and then, before the pavement material 3 completely hardens, the pavement forming member 1 is placed with the protruding portion 20 facing downward, and the pavement forming member 1 is pressed with a roller or the like. This causes the pavement forming member 1 to be pressed into the layer of pavement material 3. Thereafter, as shown in FIG. 3(b), if the pavement forming member 1 is removed before the pavement material 3 completely hardens, the pavement 4 is completed as the pavement material 3 subsequently hardens.

[0009] In the above pavement 4, drainage holes 5 are formed in the protruding parts 20. It is preferable that the protruding parts 20 reach the roadbed 2 when pressed by a roller or the like (FIG. 3(a)). For example, it is advisable to set the height of the pavement forming member 1 (the total height of the base material 10 and the protruding parts 20) to be equal to or greater than the thickness H of the pavement 4. This makes it possible to form drainage holes 5 that penetrate from the road surface 6 to the roadbed 2. If the protruding parts 20 are tapered, it becomes easier to form drainage holes 5 that penetrate from the road surface 6 to the roadbed 2.

[0010] In the above pavement 4, water from the road surface 6 can permeate into the roadbed 2, so the road surface 6 has good drainage and flooding / pooling can be prevented. By forming drainage holes 5 that reach the road surface 6 to the roadbed 2, the drainage of the road surface 6 is improved. The grooves formed in the base material 10 are expected to guide water from the road surface 6 to the drainage holes 5, which will also improve drainage. The grooves form a mesh pattern, improving the aesthetics / landscape. If the protrusions 20 are tapered, the water from the road surface 6 will flow down along the slope of the drainage holes 5, further improving drainage.

[0011] Other pavement forming methods are also possible. For example, the pavement forming member 1 is placed on the roadbed 2 with the protruding portion 20 facing downward before the pavement material 3 is poured, the pavement material 3 is poured on top of it, and then pressed with a roller or the like, the pavement forming member 1 is removed before the pavement material 3 is completely solidified, and then the pavement material 3 is solidified, so that the same pavement 4 as above can be formed.

[0012] It is also possible to form drainage holes 5 and / or grooves in the solidified pavement 4 by heating or red-heating the pavement forming member 1 with a heating means such as an electric heating wire. The heating means may be formed, for example, only on the protrusion 20, or on both the base material 10 and the protrusion 20. The pavement forming member 1 with the protrusion 20 facing downward is placed on the solidified pavement 4, the protrusion 20 (or the base material 10 and the protrusion 20) is heated, and the pavement forming member 1 is pressed from above with a roller or the like, and then the pavement forming member 1 is removed. In this case, the same pavement 4 as above can be formed, and the drainage holes 5 and / or grooves can be formed on the road surface 6 that has already been laid (for example, solidified several days, several years, or several decades ago).

[0013] The dimensions, shapes, arrangements, numbers, materials, etc. of the pavement forming members 1 and their elements described in the above embodiment are merely examples, and other embodiments are possible. [Explanation of symbols]
