[0011] A road surface forming auxiliary member 1 and a road surface forming method according to an embodiment of the present invention will be described below with reference to FIGS.
[0012] The road surface forming auxiliary member 1 is used when forming a road surface using road surface forming materials such as concrete, mortar, cement, or asphalt, and as shown in Figures 1 and 2, it comprises a main body 2 and a lid 3.
[0013] The main body 2 has a plurality of water storage members 22 extending in a net shape, each having a pair of opposing wall portions 21, and is placed on a placement surface (crushed stone Y laid on the ground X in FIG. 1).
[0014] In this embodiment, the multiple water storage members 22 extend in a lattice pattern, as shown in Figure 2. The material of the main body 2 is preferably flexible, such as resin or biodegradable plastic. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.
[0015] In this embodiment, as shown in FIG. 2, the pair of wall portions 21 are arranged so that the distance between them increases from top to bottom.
[0016] In the main body 2, a unit space A is defined by being surrounded by a plurality of water storage members 22, as shown in Figure 2. The unit space A is the area in which one road surface is formed when the road surface forming material described below is poured in.
[0017] The lid portion 3 is disposed on the upper side of the pair of wall portions 21 in order to at least partially close the upper surface side of the water storage space B formed between the pair of wall portions 21.
[0018] In this embodiment, as shown in Fig. 2, the lid portion 3 is configured to close the entire space between the pair of wall portions 21. The lid portion 3 is joined to the upper side between the pair of wall portions 21, but is configured to be able to be opened after the road surface molding material, which will be described later, has been poured in. In this embodiment, as shown in Fig. 3, a step 31 is provided between the lid portion 3 and the pair of wall portions 21, and the lid portion 3 is opened by cutting the lid portion 3 along the step 31 using a saw or the like. In this case, it is preferable that the cut-out portion be molded thinner than the non-cut-out portion.
[0019] Returning to the explanation of the main body 2, the lower surface side of the water storage member 22 is at least partially open.
[0020] In this embodiment, as shown in FIG. 4, the lower surface side of the water storage member 22 is entirely open.
[0021] At the portion where one water storage member 22 intersects with another water storage member 22, a pair of wall portions 21 are opened so that the water storage space B of the one water storage member 22 communicates with the water storage space B of the other water storage member.
[0022] In this embodiment, with the above-described configuration, as shown in FIG. 4, one water storage member 22 and another water storage member 22 are in communication with each other in a lattice pattern.
[0023] The wall portion 21 has a lower end that is partially cut out or partially hollowed out to form an insertion hole 23 through which a reinforcing member can be inserted across the plurality of water storage members 22.
[0024] In this embodiment, as shown in FIG. 5, the lower end of the wall portion 21 is cut out in an inverted U shape to form the insertion hole 23.
[0025] As will be described later, road surface molding material such as concrete is poured into unit space A, and the reinforcing members work together with the hardened road surface molding material to increase the strength of the entire road surface, and could be, for example, steel bars.
[0026] Furthermore, between the pair of wall portions 21, a tunnel-shaped partition member 24 is provided to separate the water storage space B from the insertion space C formed by the insertion hole 23.
[0027] In this embodiment, as shown in FIG. 5, a tunnel-shaped partition member 24 having substantially the same inverted U-shape as the insertion hole 23 is provided.
[0028] This partition member 24 allows a reinforcing member to be placed in the area where the road surface molding material is poured, while preventing the road surface molding material from flowing into the water storage space B when the road surface molding material described below is poured into the unit space A.
[0029] Furthermore, when the insertion holes 23 are formed at the lower end of the wall portion 21, simply by placing the reinforcing members on the mounting surface so as to correspond to the insertion holes 23 and then placing the main body portion 2 on top of them, it becomes possible to place the reinforcing members in the insertion holes 23. For example, rod-shaped reinforcing bars may be arranged in a lattice pattern, or lattice-shaped reinforcing bars may be arranged corresponding to all or some of the insertion holes 23.
[0030] The partition member 24 does not have to be provided between the pair of wall portions 21 from the beginning, and may be attached later.
[0031] The insertion holes 23 also function to form crack prevention joints, the details of which will be described later.
[0032] As shown in Figure 2, the main body 2 has a connection portion 25 on its lateral end portion, and by connecting the connection portion 25 of one road surface molding auxiliary member 1 with the connection portion 25 of another road surface molding auxiliary member 1, the water storage space B of the one road surface molding auxiliary member 1 and the water storage space B of the other road surface molding auxiliary member 1 are connected, and a new unit space A is defined by the water storage member 22 of the one road surface molding auxiliary member 1 and the water storage member 22 of the other road surface molding auxiliary member 1.
[0033] In this embodiment, the connection portions 25 are provided at both ends in the extension direction of the water storage member 22 (pair of wall portions 21). For example, a concave portion may be provided on the inner surface of the open end of one water storage member 22 (pair of wall portions 21) and a convex portion may be provided on the outer surface of the open end of the other water storage member 22 (pair of wall portions 21), and the two may be connected to each other.
[0034] This makes it possible to define a large number of unit spaces A by the large number of water storage members 22 while allowing the large number of water storage members 22 to communicate with each other internally.
[0035] Under the above configuration, road surface molding material is poured into unit space A, and when the poured road surface molding material hardens and the lid portion 3 is opened, a road surface is formed in which a drainage channel to the placing surface is formed by multiple interconnected water storage spaces B.
[0036] As a result of forming a drainage channel in this way, surface water seeps into the ground below the road surface, preventing environmental problems such as subsidence due to a lack of water underground. Furthermore, by connecting multiple water storage spaces B, surface water is dispersed throughout the entire main body 2, allowing the surface water to seep evenly into the ground and preventing the surface water from concentrating and draining in a specific area, thereby preventing environmental problems such as river flooding. Furthermore, when there is a large amount of water underground, it is stored in the water storage space B, automatically adjusting the amount of water underground. Furthermore, by using the road surface forming auxiliary member 1, it is no longer necessary to create a water gradient for drainage, making it possible to form a level road surface.
[0037] Furthermore, in the road surface molding auxiliary member 1 according to this embodiment, the unit space A into which the road surface molding material is poured is defined by a plurality of water storage members 22 extending in a net-like pattern, so that the road surface that is molded is not a monolith but is divided into unit spaces A, making the road surface less susceptible to distortion and cracking.
[0038] In addition, the pair of wall portions 21 are arranged so that the distance between them increases from top to bottom, which reduces the area of the drainage channel exposed to the road surface while allowing a large amount of water to be stored inside the water storage member 22. Furthermore, the wider spacing at the bottom increases stability on the placement surface, preventing the road surface forming auxiliary member 1 from moving during the road surface forming process.
[0039] Next, a road surface forming method using the road surface forming auxiliary member 1 will be described with reference to the flowchart of FIG.
[0040] First, the main body 2 is placed on the placement surface with the lid 3 facing upward (S1), and a rod-shaped reinforcing member is inserted into the insertion space C formed by the placement surface and the partition member 24 (S2).
[0041] Next, the road surface molding material is poured into the unit space A (S3). More specifically, it is poured in to a height substantially equal to that of the lid portion 3.
[0042] Thereafter, the lid 3 is opened (S4), and the poured road surface molding material hardens (S5: YES), completing the road surface with drainage channels formed (S6), as shown in Figure 7. Note that Figure 7 is a diagram showing a road surface formed by multiple connected road surface molding auxiliary members 1.
[0043] The road surface formed in this way is not monolithic, but is divided into unit spaces A, making it less susceptible to distortion and cracking.
[0044] Furthermore, the road surface molding material poured into unit space A also flows into insertion space C, so that road surface molding material poured into adjacent unit spaces A will bond with each other via insertion space C. At this time, the part of the hardened road surface molding material that has hardened within insertion space C functions as a crack prevention joint and is more likely to crack than other parts, which also helps to prevent the road surface from cracking.
[0045] Furthermore, the lid portion 3 only needs to be opened after the poured road surface molding material has hardened to the extent that it does not lose its shape, and may be opened after the road surface molding material has hardened.
[0046] In this way, with the road surface forming auxiliary member 1 and road surface forming method of this embodiment, it is possible to form a road surface such as a parking lot with a drainage channel simply by placing the road surface forming auxiliary member 1 and pouring in the road surface forming material, so it can also be used by individuals for DIY purposes.
[0047] As described above, in the road surface molding auxiliary member 1 and road surface molding method of this embodiment, a plurality of water storage members 22, each having a pair of opposing wall portions 21, extend in a net-like pattern, and a unit space A into which road surface molding material is poured is defined by being surrounded by the plurality of water storage members 22.
[0048] With this configuration, the road surface is not formed as a single block, but is divided into unit spaces A, making the road surface less susceptible to distortion and cracking.
[0049] In addition, in the road surface forming auxiliary member 1 and road surface forming method according to this embodiment, the wall portion 21 has its lower end partially cut out or partially hollowed out to form an insertion hole 23 through which a reinforcing member can be inserted across multiple water storage members 22, and a tunnel-shaped partition member 24 is provided between the pair of wall portions 21 to separate the water storage space B from the insertion space C formed by the insertion hole 23.
[0050] With this configuration, it is possible to place a reinforcing member where the road surface molding material is poured, while preventing the road surface molding material from flowing into the water storage space B when it is poured into the unit space A. In addition, the hardened portion within the insertion space C functions as a crack prevention joint and is more likely to crack than other portions, thereby suppressing cracking of the road surface. Furthermore, if the insertion hole 23 is formed at the lower end of the wall portion 21, it is possible to place the reinforcing member within the insertion hole 23 simply by placing the reinforcing member on the mounting surface so that it corresponds to the insertion hole 23 and then placing the main body portion 2 on top of it.
[0051] In addition, in the road surface molding auxiliary member 1 and road surface molding method according to this embodiment, by connecting the connection portion 25 of one road surface molding auxiliary member 1 with the connection portion 25 of another road surface molding auxiliary member 1, the water storage space B of the one road surface molding auxiliary member 1 and the water storage space B of the other road surface molding auxiliary member 1 are connected, and a new unit space A is defined by the water storage member 22 of the one road surface molding auxiliary member 1 and the water storage member 22 of the other road surface molding auxiliary member 1.
[0052] With this configuration, it is possible to define a large number of unit spaces A using a large number of water storage members 22 while connecting them internally, thereby making it possible to form a wide road surface made up of road surfaces separated by unit spaces A.
[0053] The road surface forming auxiliary member and road surface forming method of the present invention are not limited to the above-described embodiment, and various modifications and improvements are possible within the scope of the claims.
[0054] For example, in the above embodiment, the insertion holes 23 are formed by cutting out an inverted U-shape in the lower end of the wall portion 21. However, as shown in Fig. 8, the insertion holes 23 may be formed by hollowing out a portion. In this case, it is possible to arrange the rod-shaped reinforcing member above the mounting surface. In this case, a tunnel-shaped partition member 24 having a shape corresponding to the hollowed-out insertion holes 23 is arranged between the pair of wall portions 21.
[0055] Furthermore, it is not essential to insert a rod-shaped reinforcing member through the insertion hole 23, and in that case, the insertion hole 23 does not need to be formed. Even in this case, the insertion hole 23 functions to form a crack prevention joint, and the partition member 24 prevents the road surface molding material from flowing into the water storage space B.
[0056] Furthermore, in the above embodiment, the lid 3 is opened by cutting it along the step 31 using a saw or the like, but it is also possible to open the lid 3 by making a cut in the same position as the step 31 and then hitting or peeling off the lid 3. In this case as well, it is preferable to mold the part to be opened thinner than the other parts.
[0057] The lid 3 may also be separate from the main body 2. In the case of a separate part, it is possible to arrange the lid 3, which corresponds to the mesh shape of the main body 2 as shown in Fig. 9, on a pair of wall parts 21 before pouring the road surface molding material into the unit space A (S3 in Fig. 6).
[0058] In particular, in the case where the lid portion 3 is configured to be positioned on the upper side of a pair of wall portions 21 and has multiple through holes 32 formed therethrough in the vertical direction, as shown in Figure 9, the step of opening the lid portion 3 in S4 of Figure 6 is also unnecessary.
[0059] The road surface molding material is poured in to approximately the same height as the lid portion 3, but in order to prevent the road surface molding material from flowing into the water storage space B through the through hole 32, it is preferable to block the through hole 32 with a blocking member such as tape before step S3 in Figure 6.
[0060] Furthermore, as shown in FIG. 10, the cover 3 may be configured in the shape of a rail with a recessed bottom, while being placed on the upper side of the pair of wall portions 21 so as to fit into the water storage member 22.
[0061] In this case, the lid portion 3 can be easily fixed in the left-right direction to the water storage member 22, and the rail-shaped lid portion 3 fitted into the water storage member 22 covers the top of the water storage member 22, thereby preventing road surface molding material from flowing into the water storage space B through the gap between the lid portion 3 and the water storage member 22.
[0062] Furthermore, in the above embodiment, the main body 2 is placed on crushed stone Y (corresponding to the "placing surface") laid on the ground X, but it may also be placed directly on the ground X, in which case the ground X corresponds to the "placing surface."
[0063] In addition, in order to prevent road surface molding material from flowing into the water storage space B from between the lower end of the water storage member 22 (wall portion 21) and the placing surface, a flat rib extending outward from the lower end of the water storage member 22 (wall portion 21) may be provided.
[0064] In the above embodiment, the main body 2 is made of a flexible material, but the material is not necessarily limited to a flexible material. Similarly, the material of the water storage member 22 is not limited to a metal. [Explanation of symbols]
