However, most of the above-mentioned pavement materials are impermeable to water, and some include materials having a water absorption rate, but the water absorption as a whole is not good. When the amount of rainfall increases, water absorption by the pavement material decreases, and in the pavement, water overflows into the pavement and flows on the pavement, causing various inconveniences. The same applies to the case where it is used as an outdoor floor material such as a rooftop or a balcony. Furthermore, in recent years, particularly in summer, due to the heat island phenomenon caused by asphalt pavement and the like, the temperature tends to rise particularly in large cities such as Tokyo. Further, there is a strong demand for outdoor flooring materials that can be used for outdoor greening of buildings and balconies of houses and the like. The present invention has been made in view of the above conventional circumstances, and an object of the present invention is to provide a pavement material and an outdoor floor material that can mitigate the increase in the temperature of the pavement due to flooding of the pavement due to heavy rain and heat. .

Preferably. Depending on the construction conditions, it may give appropriate elasticity without adding the inorganic substance. Then, it is cut into a regular shape (square shape or the like) or an irregular shape by a press machine, and by interlocking the three-dimensional mesh structure bodies 2 with each other, they can be connected to each other and laid on a pavement or the like. In this case, the gap 4 may be provided during construction (see FIGS. 1 and 3). Polypropylene (PP) is exemplified as the material of the three-dimensional network structure 2, and details and manufacturing method thereof will be described later.

(Application example and effect) An application example of the above pavement material 1 is shown in FIGS. The ground is leveled, the three-dimensional mesh structure 2 is laid, and the water-permeable pavement board 3 is laid on it. As a result, the pavement board 3 absorbs water, and the water permeates from the pavement board 3 into the three-dimensional network structure 2 and the water flows through the three-dimensional network structure 2 to release the water. It is possible to prevent flooding of the pavement even with heavy rain. In other words, it serves as a water conduit such as a water outlet or a gutter. Further, since the pavement plate 3 and the three-dimensional network structure 2 can contain water, this is effective in lowering the temperature than asphalt, especially in the summer. Even if the water evaporates from the pavement material 1, it is possible to ventilate the three-dimensional mesh structure 2, and therefore it is considered that there is a temperature suppressing effect. In particular, water can be added to the pavement material 1 by sprinkling water at the time of drying, but the water sprinkled also functions as cooling water inside the pavement plate 3 and the three-dimensional mesh structure 2 at this time. The control effect is also higher than that of conventional concrete paving stones and asphalt.

Besides the pavement, the same effect can be expected when it is used for paving a plaza or a park, or when it is laid as an outdoor floor material such as a rooftop or a veranda. It is also possible to sprinkle clean water, collect it, and reuse it as cooling water or the like. The paving board 3 can also be applied to ordinary tiles, mortar boards, bricks, deck materials, etc. that do not have water absorbability, and the three-dimensional mesh structure from the gap 4 of the laid paving board 3 Since water permeates into No. 2, the same effect can be expected in suppressing flooding and temperature rise. Further, even if sand or the like is clogged in the three-dimensional network structure 2, it can be easily replaced, and the three-dimensional network structure 2 is formed in an irregular shape with respect to the pavement plate 3 such that its edges are jagged. In this case, the engagement is good, the shift is unlikely to occur, and the workability is improved. If various sizes and forms are set in advance, size adjustment and the like become easy.

Further, since the above-mentioned three-dimensional mesh structure 2 can have various forms, its configuration will be described in detail. As shown in FIG. 5, the first specific example thereof is a plate-shaped three-dimensional network in which a recycled thermoplastic resin is used as a raw material or a main raw material, and a plurality of filaments are randomly entangled in a spiral shape and partially heat-bonded. The structure 501. It is preferable that the density of one side, both sides, three sides or four sides of the three-dimensional network structure is relatively lower than the density of the portion excluding the front side. Flake-shaped or chip-shaped PP (polypropylene) is used as the raw material or main raw material of the recycled thermoplastic resin. It is a PET bottle crushed as it is and melted into a flake shape. It is also suitable for the age of recycling promotion. If this is a genuine product, not a recycled product, it will be costly to dry and crystallize or remove dust.
The manufacturing cost per m 2 doubles. It can exert its power in reducing the disposal cost. It is also applicable to thermoplastic resins other than PP. For example, as the thermoplastic resin, polyolefin such as polyethylene, polyester such as polyethylene terephthalate (PET), polyamide such as nylon 66, polyvinyl chloride, polystyrene, a copolymer or elastomer obtained by copolymerizing the above resin as a base,
The thing etc. which blended the said resin are mentioned. Other,
Inorganic substances such as talc can also be used. For example, there is a container for warming food in a microwave oven, but a large amount of end material generated during injection in the manufacturing process is generated, which can be effectively used. By using an inorganic material such as talc, a material having high rigidity can be obtained.

Further, the three-dimensional three-dimensional network structure 501 is applied to the paving material as described above. In the first specific example, the inside is molded to have a uniform density. The apparent density is preferably 0.02 to 0.9 g / cm 3 (porosity corresponds to 36 to 98.4%), and is 0.05
It is particularly preferably 0.15 g / cm 3 . The three-dimensional three-dimensional network structure 1 has a width of 0.1 m to 2 m and a thickness of 5 mm, for example.
200 mm is preferable, it is endless in the length direction, and cut to an appropriate length (for example, 900 mm), but it is not limited to these size examples. Further, the surface of the three-dimensional mesh structure 501 can be a modified surface such as a convex surface.

A three-dimensional three-dimensional network structure 50 of the third embodiment.
3 (see FIG. 6 (b)) is a three-sided molding in which the other surface is not uniform, and the density is increased in the region at a predetermined interval from the other surface of the second specific example toward the inside. It is molded high, and the density of the region inside the central part is set lower than that. Various forms can be manufactured as compared with the second specific example. Three-dimensional three-dimensional network structure 503
The end-face joining has the advantage that it is not processed in the subsequent process. In the second specific example, since the density is low and both sides of the long side of the aggregate are in contact with the endless conveyor, the surface is substantially flattened, but the left and right end faces of the aggregate have irregular chaotic spiral shapes. However, in the third specific example, at least one side is molded.

Both or one surface of the molten thermoplastic resin aggregate is dropped onto the endless conveyors 514 and 515 and moves to the inside of the molten thermoplastic resin aggregate to form a dense state. The porosity is smaller than that in the central part where it dropped into the water. As a matter of course, in the surface portion where the porosity is low, the number of intersections is larger than in the central portion where the porosity is high, and the tensile strength is remarkably stronger. In addition, the surface area having a low porosity has a small area of the voids, and thus microorganisms are easily proliferated.

A variety of three-dimensional network structures can be realized by combining shapes such as irregular shapes (pipe, Y shape) and combinations thereof. In addition, the three-dimensional net-like structure is rolled into a sheet structure of a super-dense structure by roll compression of a take-up machine. Contacting the take-up conveyor that forms the shape on the three or four sides of the aggregate of the molten resin extruded during the production of the three-dimensional reticulated sheet by making the die internal pressure uniform so that the recycled PET resin is evenly discharged from the die I decided to do it. In other words, the molten recycled PET resin aggregate is formed into a shape corresponding to the product shape on the three-sided or four-sided surface portion. For example, if necessary, the resin aggregate is collected on a polygonal conveyor to form a product. As one of the methods for obtaining a three-dimensional reticulated sheet, the three-dimensional reticulated sheet is extruded downward from a plurality of dice of molten resin and naturally descended between the water surface or a partially submerged conveyor to create a random spiral shape. Becomes Sheet width 1.0m, thickness 100
In the case of mm, it was confirmed that the density changes by changing the speed of the endless conveyor to confirm that the density changes. Furthermore, it was confirmed that the density changed with the change of the discharge amount of the extruder.

In the concrete example of FIG. 14, in the four-sided molding three-dimensional network structure manufacturing apparatus 550, the above-mentioned endless member 51 is used.
2 and 513 are rolls 556 only, and a single or a plurality of protrusions 560a to 560c are formed on the surface thereof. This is because a recess is formed on the side surface of the three-dimensional network structure. Protrusion 56 of rolls 556 and 557
0a to 560c are formed in an arc shape with a rectangular cross section. Theoretically the depression should be square,
Since the resin thread falls from the top as described above, a blind is formed, and in fact, a region where the resin thread does not enter is formed, so that the concave portion on the side surface of the three-dimensional network structure has a curved shape. In other words, it feels like taking an earl. It is also possible to put a cam and a spring in the roll 556 described above, and to synchronize the rotation of the protrusion with the cam so that the cam pushes the protrusion outward. The blinds can be reduced and more precise recesses can be created. According to this method, it is possible to form the key-like one in which the side face that can be fitted in parallel is formed with a recess. The other structures are similar to those of the three-dimensional network structure manufacturing apparatus 550, and thus the drawings and the description are incorporated.
