Description

[Technical field]

[0001] The present invention relates to a road surface forming auxiliary member that is capable of forming a road surface that has a drainage channel and is suppressed from cracking. [Background technology]

[0002] Conventionally, a road surface molding auxiliary member has been proposed which comprises a main body portion having a plurality of first through holes formed at each of a plurality of intersections of a plurality of communicating pipes arranged in a network pattern, and a plurality of tubular portions each protruding from the main body portion and having a plurality of second through holes each communicating with the plurality of first through holes, and which is characterized in that a drainage channel is formed by the second through holes, the first through holes and the communicating pipes when concrete or the like is poured into the portions of the main body portion other than the second through holes when the main body is placed on a supporting surface (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7028422 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when using the above-mentioned road surface forming auxiliary member, the formed road surface becomes a single block, which causes problems in that it is prone to distortion and cracks tend to appear in noticeable parts of the road surface.

[0005] Therefore, an object of the present invention is to provide a road surface forming auxiliary member that is capable of forming a road surface that has a drainage channel and is suppressed from cracking. [Means for solving the problem]

[0006] The present invention relates to a road surface forming auxiliary member that is placed on a placement surface when forming a road surface, the auxiliary member comprising: a main body portion in which at least two water storage members extending in a substantially horizontal direction intersect; and an engagement portion provided on the end side of the water storage members; the water storage members each comprise a pair of wall portions extending in the substantially horizontal direction and facing each other; and a plurality of connection portions that partially connect the upper portions of the pair of wall portions together; and in the upper portions of the pair of wall portions, in the portions where the connection portions are not present, a through hole is formed that communicates with a water storage space formed between the pair of wall portions; and the pair of wall portions The lower portion of each of the road surface molding auxiliary members is at least partially open, the water storage spaces of the two intersecting water storage members are connected, the engaging portion of one road surface molding auxiliary member is engageable with the engaging portion of the other road surface molding auxiliary member, and when the engaging portions engage with each other, a pouring space surrounded by a plurality of the water storage members is formed, and when the road surface molding material poured into the pouring space hardens, a road surface is formed that allows water to flow into the water storage space from the through hole.

[0007] According to this configuration, the road surface molding material cast into the casting space hardens, making it possible to mold a road surface with a drainage function that allows water to flow into the water storage space from the through holes. At this time, since the casting space is defined by multiple water storage members, a road surface that is not a single block but is divided into each casting space is molded, so that distortion and cracking of the road surface are suppressed. In addition, since the through holes are molded by the connecting parts partially connecting the upper parts of the pair of wall parts, it is possible for rainwater to flow into the water storage space from the through holes while preventing large garbage from flowing into the water storage space by the connecting parts. Furthermore, since the casting space is formed by combining multiple road surface molding auxiliary members, and each road surface molding auxiliary member does not have a space for the casting space, the storage space for the road surface molding auxiliary members when not in use can be reduced, and transportation is also made easier.

[0008] According to another aspect of the present invention, there is provided a road surface forming method using the above-mentioned road surface forming auxiliary member. Effect of the Invention

[0009] According to the road surface forming auxiliary member and road surface forming method of the present invention, it is possible to form a road surface in which drainage channels are formed and which is suppressed from cracking. [Brief description of the drawings]

[0011] Hereinafter, a road surface forming auxiliary member 1 and a road surface forming method according to an embodiment of the present invention will be described with reference to Figs.

[0012] The road surface molding auxiliary member 1 is placed on a supporting surface (such as crushed stone laid on the ground) when molding a road surface using road surface molding materials such as concrete, mortar, cement, or asphalt, and as shown in Figures 1 and 2, it has a main body portion 2 and an engagement portion 3.

[0013] The main body 2 has a configuration in which at least two water storage members 21 extending in a substantially horizontal direction intersect with each other. In this embodiment, the two water storage members 21 intersect at a substantially right angle in their center portions.

[0014] The engagement portion 3 is provided on the end side of the water storage member 21.

[0015] Resin, biodegradable plastic, etc. may be used as the material for the main body 2 and the engagement portion 3. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

[0016] The water storage member 21 includes a pair of wall portions 22 that extend substantially horizontally and face each other, and a plurality of connection portions 23 that partially connect the upper portions of the pair of wall portions 22 to each other.

[0017] In the upper portion of the pair of wall portions 22, in a portion where no connecting portion 23 exists, a through hole H is formed which communicates with the water storage space S1 formed between the pair of wall portions 22. That is, a grating is formed by the multiple connecting portions 23. In this embodiment, the multiple through holes H are formed at approximately equal intervals by the multiple connecting portions 23 which are arranged at approximately equal intervals.

[0018] The water storage spaces S1 of the two intersecting water storage members 21 are connected to each other as shown in Fig. 3. Note that Fig. 3 shows a state in which the two road surface forming auxiliary members 1 are engaged with each other, but the engagement of the road surface forming auxiliary members 1 will be described later.

[0019] As shown in Figs. 1 and 2, a groove 24 is formed in the upper portion of the water storage member 21 along the extending direction thereof, into which a closing member (not shown) for closing the through hole H can be fitted.

[0020] The blocking member may be a long piece of resin having a width that is just large enough to fit into the groove 24 .

[0021] The space between the lower portions of the pair of wall portions 22 is at least partially open, as shown in Fig. 3. In this embodiment, the space between the lower portions of the pair of wall portions 22 is assumed to be almost entirely open.

[0022] The engaging portion 3 of one road surface forming auxiliary member 1 is capable of engaging with the engaging portion 3 of another road surface forming auxiliary member 1, as shown in Figs.

[0023] 2, in this embodiment, the engaging portion 3 protrudes from one of the left and right sides in the extension direction of the water storage member 21, and when the two engaging portions 3 are engaged, they abut each other at their sides, and the tip of each engaging portion 3 abuts against the end portion (the portion where the engaging portion 3 does not protrude) of the water storage member 1 of the other road surface forming auxiliary member 1. Details of the engagement of the two engaging portions 3 will be described later.

[0024] When the engaging portions 3 are engaged with each other, a driving space S2 surrounded by a plurality of water storage members 21 is formed as shown in FIG.

[0025] A road surface molding material such as concrete is poured into the pouring space S2, and as the poured road surface molding material hardens, a road surface with a drainage function that allows water to flow into the water storage space S1 through the through holes H is formed. The method of forming the road surface will be described later.

[0026] In this embodiment, the ends of the engagement portions 3 and the ends of the water storage member 1 where the engagement portions do not protrude are blocked, and as shown in Figure 3, even if the engagement portions 3 are engaged with each other, the water storage spaces S1 are not directly connected to each other.

[0027] In addition, in this embodiment, as shown in Figure 1, a planar rib 25 extending outward (toward the casting space S2) from the lower end of the water storage member 21 (wall portion 22) is provided to prevent the poured road surface molding material from flowing into the water storage space S1 from the lower end of the water storage member 21.

[0028] As shown in Fig. 1, a recess 26 is formed on the end side of the water storage member 21, and as shown in Fig. 5, the recess 26 is formed at a position where a rod-shaped reinforcing member B can be placed across the two recesses 26 when the engaging parts 3 are engaged with each other. Fig. 1 shows an example where the recess 26 is formed in the engaging parts 3.

[0029] As will be described later, road surface molding material is poured into the pouring space S2, and the rod-shaped reinforcing members B work together with the hardened road surface molding material to increase the strength of the entire road surface, and could be, for example, reinforcing bars. Figure 5 shows an example in which rod-shaped reinforcing bars are arranged in a lattice pattern.

[0030] By bridging the rod-shaped reinforcing member B across the two recesses 26, the positions of the two road surface forming auxiliary members 1 are prevented from shifting due to the influence of unevenness or the like.

[0031] In this embodiment, as shown in Figure 1, an engagement auxiliary protrusion 31 is also provided on the end side of the water storage member 21 in addition to the engagement portion 3, and the engagement auxiliary protrusion 31 of one road surface forming auxiliary member 1 can engage with the engagement auxiliary protrusion 31 of another road surface forming auxiliary member 1, thereby assisting the engagement between the engagement portions 3.

[0032] The recesses 26 also function to form crack prevention joints, the details of which will be described later.

[0033] As shown in FIG. 6, a cover member 4 that covers the rod-shaped reinforcing member B and whose upper end is connected to the upper portion of the water storage member 21 can be fitted into the upper portion of the recess 26.

[0034] In this embodiment, as shown in FIG. 7, a cover side groove portion 41 continuing to the groove portion 24 is formed in the upper portion of the cover member 4.

[0035] Resin, biodegradable plastic, etc. may be used for the cover member 4. However, when asphalt is used as the road surface molding material, it is preferable to use a heat-resistant material.

[0036] In this manner, the road surface is formed with a plurality of road surface forming auxiliary members 1 assembled together.

[0037] Next, a road surface forming method using the road surface forming auxiliary member 1 will be described with reference to the flowchart of FIG.

[0038] First, the engaging portions 3 of four or more road surface forming auxiliary members 1 are engaged with each other on a placement surface (S1). As a result, a casting space S2 surrounded by the four water storage members 21 is formed.

[0039] Next, a rod-shaped reinforcing member B is placed across the two recesses 26 that overlap due to the engagement of the engaging portions 3 (S2), a cover member 4 is fitted into the upper part of the recesses 26 (S3), and a blocking member is fitted into the groove portion 24 of the water storage member 21 and the cover side groove portion 41 of the cover member 4 (S4).

[0040] Next, the road surface molding material is poured into the pouring space S2 (S5). More specifically, the road surface molding material is poured up to a height near the top of the water storage member 21. However, if the road surface molding material can be poured so as not to flow into the through hole H, the above S4 may be omitted.

[0041] Thereafter, when the road surface molding material has hardened (S6: YES), the blocking members are removed (S7), and the road surface with the drainage channel formed is completed (S8), as shown in Figure 9. The blocking members may be removed when the road surface molding material has hardened to the point where it does not flow.

[0042] The road surface formed in this manner is not a single block but is divided into individual driving spaces S2, thereby suppressing distortion and cracks.

[0043] Furthermore, the road surface molding material poured into the casting space S2 also flows into the recesses 26, so that the road surface molding material poured into adjacent casting spaces S2 bond to each other via the recesses 26. At this time, of the hardened road surface molding material, the portion that has hardened within the recesses 26 functions as a crack prevention joint and is more likely to crack than other portions, which also helps to prevent the road surface from cracking.

[0044] Furthermore, in S3, if the cover member 4 is not fitted, adjacent driving spaces S2 will be connected to each other at the top of the recess 26, making the connected parts more susceptible to cracking; however, since the upper end of the cover member 4 is connected to the top of the water storage member, an independent road surface is formed for each driving space S2, thereby preventing the road surface from cracking.

[0045] As a result of the road surface being molded in this manner, the surface water flowing into the water storage space S1 through the through holes H of each road surface molding auxiliary member 1 will seep into the ground below the road surface, and environmental problems such as subsidence due to lack of water in the ground are suppressed. In addition, since the road surface molded by the road surface molding auxiliary member 1 has a drainage function, it is not necessary to provide a water gradient for drainage, and it is possible to mold a level road surface. Since the molded road surface is level, the surface water is dispersed into the water storage space S1 of each road surface molding auxiliary member 1, making it possible for the surface water to seep evenly into the ground and preventing the surface water from concentrating and being drained in a specific place, thereby suppressing environmental problems such as river flooding. In addition, when the amount of water in the ground is large, the water is stored in the water storage space S1, so the amount of water in the ground is automatically adjusted.

[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 that has drainage function and is less likely to crack simply by combining multiple road surface forming auxiliary members 1 and pouring in the road surface forming material, so that it can also be used by individuals for DIY road surface forming for parking lots, etc.

[0047] As described above, in the road surface forming auxiliary member 1 and road surface forming method of this embodiment, a through hole H communicating with the water storage space S1 is formed in the upper part of the pair of wall portions 22 where the connection portion 23 is not present, and the engagement portions 3 are engaged with each other to form a casting space S2 surrounded by a plurality of water storage members 21.

[0048] According to this configuration, the road surface molding material cast into the casting space S2 hardens, making it possible to mold a road surface with a drainage function that allows water to flow into the water storage space S1 from the through hole H. At this time, since the casting space S2 is defined by a plurality of water storage members 21, a road surface that is not a single rock but is divided into each casting space S2 is molded, so that distortion and cracks of the road surface are suppressed. In addition, since the through hole H is molded by the connection part 23 partially connecting the upper parts of the pair of wall parts 22, it is possible for rainwater to flow into the water storage space S1 from the through hole H while preventing large garbage from flowing into the water storage space S1 by the connection part 23. Furthermore, since the casting space S2 is formed by combining a plurality of road surface molding auxiliary members 1, and the road surface molding auxiliary member 1 alone does not have a space for the casting space S2, the storage space when not in use of the road surface molding auxiliary member 1 can be reduced, and transportation is also made easier.

[0049] Furthermore, in the road surface forming auxiliary member 1 according to this embodiment, the recesses 26 are formed in positions where a rod-shaped reinforcing member B can be placed across the two recesses 26 when the engaging portions 3 are engaged with each other.

[0050] With this configuration, it is possible to place a rod-shaped reinforcing member B such as a reinforcing bar on the recess 26, thereby increasing the strength of the road surface when the road surface molding material hardens. In addition, since the rod-shaped reinforcing member B is placed across the two recesses 26, it is possible to prevent the positions of the two road surface molding auxiliary members 1 from shifting due to the influence of unevenness, etc.

[0051] In addition, in the road surface forming auxiliary member 1 according to this embodiment, a cover member 4 that covers the rod-shaped reinforcing member B and has an upper end connected to the upper part of the water storage member 21 can be fitted into the upper part of the recess .

[0052] With this configuration, the upper end of the cover member 4 is connected to the upper part of the water storage member 21, so that the road surfaces molded in adjacent driving spaces S2 are not connected, i.e., an independent road surface is molded for each driving space S2, thereby suppressing distortion and cracking of the road surface.

[0053] Moreover, in the road surface forming auxiliary member 1 according to this embodiment, a groove portion 24 is formed in the upper portion of the water storage member 21 along the extension direction thereof, into which a closing member for closing the through hole H can be fitted.

[0054] With this configuration, a blocking member such as rubber can be fitted into the upper part of the water storage member 21, i.e., the upper part of the through hole H. By fitting the blocking member before pouring the road surface molding material, it is possible to prevent the road surface molding material from flowing into the water storage space S1 when the road surface molding material is poured.

[0055] 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.

[0056] For example, it may be desirable to drain surface water that has flowed into the water storage space S1 to a specified location.

[0057] Therefore, as shown in Figures 10 and 11, a configuration may be adopted in which "a water-conducting member 5 having a water-conducting space S3 along the water storage member 21 can be arranged at the bottom of the main body 2, and by arranging the water-conducting member 5 at the bottom of the main body 2, the water-conducting space S3 is connected to the water storage space S1, and when one road surface molding auxiliary member 1 and another road surface molding auxiliary member 1 are engaged, the water-conducting space S3 of the water-conducting member 5 arranged at the bottom of the one road surface molding auxiliary member 1 is connected to the water-conducting space S3 of the water-conducting member 5 arranged at the bottom of the other road surface molding auxiliary member 1."

[0058] 10 shows an example in which the water guide member 5 has a groove with a width corresponding to the water storage space S1, and the inside of this groove functions as the water guide space S3. Furthermore, when the water guide member 5 is placed under the main body part 2, it is preferable that it is fixed to the main body part 2. Furthermore, the water guide members 5 may be engaged with each other, and the water guide function can be obtained even if "one road surface molding auxiliary member 1 is engaged with another road surface molding auxiliary member 1, so that the water guide members 5 also abut each other."

[0059] According to this configuration, it is possible to guide the surface water that has flowed into the water storage space S1 to a desired discharge location by the water guide member 5. The surface water guided in this way can be stored at the discharge location, making it possible to efficiently store rainwater in areas with little water.

[0060] Furthermore, while the above embodiment is provided with the recess 26, a hole may be used instead of the recess 26, and the hole may be formed in a position where a rod-shaped reinforcing member B can be placed across the two holes when the engaging parts 3 are engaged with each other. In this case, since the rod-shaped reinforcing member is not placed from above, a member equivalent to the cover member 4 is provided at the engaging part 3 (or the end of the water storage member 21) from the beginning, so that an independent road surface can be formed for each driving space S2.

[0061] In addition, in the above embodiment, the rod-shaped reinforcing member B is disposed across the two recesses 26, but the rod-shaped reinforcing member B does not necessarily have to be disposed across them. Furthermore, the recesses 26 do not have to be provided. In this case, too, it is conceivable to provide a member equivalent to the cover member 4 in the engagement portion 3 (or the end of the water storage member 21) from the beginning.

[0062] Furthermore, in the above embodiment, the end of the engagement portion 3 and the end of the water storage member 1 where the engagement portion does not protrude are blocked, and even when the engagement portions 3 are engaged with each other, the water storage spaces S1 are not connected to each other. However, the end of the engagement portion 3 and the end of the water storage member 1 where the engagement portion does not protrude are open, and the water storage spaces S1 may be connected to each other when the engagement portions 3 are engaged with each other.

[0063] In addition, in the above embodiment, the road surface forming auxiliary member 1 was placed on crushed stone laid on the ground, but it may also be placed directly on the ground, in which case the ground corresponds to the “placing surface.”

[0064] In the above embodiment, resin, biodegradable plastic, or the like is used as the material for the main body 2, but other materials may also be used. [Explanation of symbols]
