[Solution] The block paving reinforcement plate consists of a base plate on which paving blocks are placed when block paving is performed, a plurality of joint plates erected on the base plate to form joints between adjacent paving blocks when paving blocks are placed, and joint plate penetrations formed in the base plate. When multiple block paving reinforcement plates are stacked, the joint plates penetrate the joint plate penetrations, and the base plates of adjacent block paving reinforcement plates come into approximate contact.

Description

Technical Field

[0001] The present invention relates to a reinforcing plate for block paving used when paving roads and the like.

Background Art

[0002] Conventionally, as a reinforcing plate for block paving used when performing block paving, there is known a "reinforcing plate for block paving characterized by comprising a base plate that can be positioned on the bottom surfaces of the left and right blocks laid through a joint portion, and a T-shaped joint plate formed to project upward from this base plate" (Patent Document 1). With such a reinforcing plate for block paving, although an appropriate joint portion can be formed between the paving blocks during use and its function can be sufficiently achieved, since it has a joint plate that projects upward, when storing, even if they are stacked, a gap corresponding to the height of the joint plate will occur between adjacent reinforcing plates for block paving, and there was a problem in that a large amount of space is required during storage, transportation, and storage until construction at the site.

[0007] The joint plate penetration portion of the reinforced block pavement plate according to claim 3 is characterized in that, of the plurality of joint plate penetration portions, some are formed in the shape of an elongated hole and the others are formed in the shape of a notch.

[0008] Claim 4 is characterized in that the bottom surface of the base plate of the reinforced block pavement plate is provided with ribs that bite into the ground during construction. The upper surface of the base plate of the reinforced block pavement plate according to claim 5 is characterized in that groove-shaped rib storage grooves into which the ribs fit are formed. [Effects of the Invention]

[0009] As is clear from the above explanation, the present invention provides the following effects. (1) In each of the inventions described in claims 1 to 3, when multiple reinforced blocks for paving are stacked, the joint boards penetrate the joint board penetrations and the base boards of adjacent reinforced blocks for paving come into contact with each other, thereby preventing the occurrence of dead space during storage or transportation and significantly reducing the stacking volume. Therefore, transportation and storage costs and space requirements can be reduced. (2) The invention described in claim 4 also provides the same effects as (1) above, and when placed on the ground, the interlocking force can be increased, preventing slippage and the like. (3) The invention described in claim 5 also provides the same effects as (1) to (2) above, and since the ribs can be stored, it prevents shifting when placed on the ground and reduces the stacking volume.

Mode for Carrying Out the Invention

[0011] Hereinafter, the present invention will be described in detail according to the mode for carrying out the present invention shown in the drawings.

[0012] In the first mode for carrying out the present invention shown in FIGS. 1 to 8, reference numeral 1 denotes a reinforced plate for block paving used when block paving a road or the like. As shown in FIGS. 1 to 5, this reinforced plate 1 for block paving has at least a base plate 4, a plurality of spacer plates 5, and spacer plate through-holes 6. Here, when explaining the configuration of the reinforced plate 1 for block paving including the reference plan view of the usage state in FIG. 7 and the reference cross-sectional view showing the paving structure of the usage state in FIG. 8, the reinforced plate 1 for block paving is placed on the upper surface of the ground 2 (see FIG. 8), and a base plate 4 on which the paving block 3 is placed on its upper surface, a plurality of spacer plates 5 erected on this base plate 4 and forming a joint portion G between adjacent paving blocks 3 when the paving block 3 is placed (see FIG. 7), and a single or a plurality of spacer plate through-holes 6 formed in the base plate 4.

[0013] In this embodiment, the base plate 4 is formed in a substantially circular plate shape. However, it can be of any shape as long as it can be placed on the upper surface of the ground 2 and the paving block 3 can be placed on the upper surface of this base plate 4. Also, for the material, a resin such as high-strength plastic is desirable, but it may be formed of metal, ceramic, or the like. Since the reinforced plate 1 for block paving is disposed on the bottom surface of the paving block 3 during use and is not exposed to sunlight and not visible to the human eye, it is desirable to reuse and utilize waste plastic.

[0014] Multiple joint boards 5 are integrally erected on the upper surface of the base plate 4 in the circumferential direction. As shown in Figures 7 and 8, when multiple paving blocks 3 are placed on the upper surface of the ground 2, the multiple joint boards 5 form intersecting linear joints G between adjacent paving blocks 3. In this embodiment, the joint boards 5 are formed in a plate shape that is roughly rectangular in front view, and a total of four are provided horizontally on the upper surface of the base plate 4. The joint boards 5 are provided at approximately 90-degree intervals so as to be rotationally symmetric with the center of the base plate 4 as the pivot point. When arranging the paving blocks 3, by positioning them so that two intersecting sides of the paving blocks 3 abut against the wide surface of the joint boards 5, an appropriate joint G can be formed between adjacent paving blocks 3. Furthermore, the base plate 4 is provided with joint plate penetrations 6 formed so that when multiple block paving reinforcement plates 1 are stacked (see Figure 6), the joint plates 5 penetrate upward, and the upper and lower surfaces of the base plates 4 of adjacent block paving reinforcement plates 1 are in approximate contact.

[0015] Each of the multiple joint boards 5 has one end formed near the lower end of one side surface, and is formed as an elongated hole with a center line that follows an arc-shaped trajectory T that passes through the approximate center of the joint board 5, with the approximate center of the base plate 4 as the center. Here, "near the lower end" includes cases where the lower end of one side surface of the joint board 5 and one end of the joint board penetration 6 are formed to be substantially on the same plane in the vertical direction, as well as cases where one end of the joint board penetration 6 is formed at a location slightly separated from the lower end of one side surface (a few millimeters apart).

[0016] By forming a joint plate penetration 6 from near the lower end of the joint plate 5 in this way, the joint plate 5 takes on the shape of a so-called L-shaped connection, allowing the reinforced blocks 1 for block paving to be stacked efficiently.

[0017] Here, an L-shaped connection refers to a shape in which the connection width of the lower end of the joint board 5 (the connection part with the base board 4) is different on the left and right sides, or is different on only one side, as shown in Figure 5. An I-shaped connection refers to a shape in which the connection width of the lower end of the joint board 5 is approximately the same on the left and right sides and has a certain width. The L-shaped connection with a small connection width at the lower end of the joint board 5 used in this embodiment allows for stacking more reinforced concrete block paving boards 1 compared to the I-shaped connection with a large connection width at the lower end of the joint board 5. Specifically, by adopting the joint board 5 and joint board penetration 6 as in this embodiment, it is possible to stack approximately three times more reinforced concrete block paving boards 1 compared to the joint board penetration 6 that can be formed in the case of an I-shaped connection.

[0018] Regarding the joint plate penetration portion 6, by forming the elongated joint plate penetration portion 6 as described above, as shown in Figure 6, multiple reinforced block paving plates 1 can be rotated and overlapped little by little, thereby almost eliminating dead space and enabling efficient storage, transportation, etc.

[0019] Furthermore, the width of the joint plate penetration portion 6 (the lengthwise dimension of the joint plate 5 in a plan view) is preferably such that the joint plate 5 can penetrate in a loosely inserted state. The circumferential length of the joint plate penetration portion 6 is preferably such that, when at least several, preferably three or more, reinforced block paving plates 1 are stacked, the joint plate 5 of the lowest reinforced block paving plate 1 can penetrate the joint plate penetration portion 6 of the uppermost reinforced block paving plate 1. More optimally, when multiple reinforced block paving plates 1 are stacked so that the base plates 4 are in approximate contact in the vertical direction, the length is such that the joint plate 5 of the lowest reinforced block paving plate 1 is approximately flush with the base plate 4 of the uppermost reinforced block paving plate 1. In other words, when multiple base plates 4 are stacked, it is desirable that the length be such that the joint plate 5 can penetrate to the extent that the thickness of the stacked multiple base plates 4 and the height of the joint plate 5 are approximately the same. In this embodiment, the thickness of the base plate 4 is 2 mm, and the height of the joint plate 5 is 25 mm. When 12 reinforced block paving plates 1 are stacked on top of each other, the thickness of the stacked base plates 4 and the height of the joint plate 5 are formed to be approximately the same. Here, "approximately the same" includes not only cases where there is a slight difference in height, but also cases where the heights are exactly the same.

[0020] The bottom surface of the base plate 4 is provided with ribs 7 that are circular in shape when viewed from the bottom and roughly trapezoidal in cross-section, which bite into the ground 2 during construction. The height of the ribs 7 is smaller than the thickness of the base plate 4. Specifically, in this embodiment, the height of the ribs 7 is 1 mm.

[0021] Furthermore, in this embodiment, a groove-shaped rib storage groove 8, which is approximately circular in plan view and into which the ribs fit, is formed on the upper surface of the base plate 4. The depth of this rib storage groove 8 is formed to be approximately the same as the height of the ribs 7. The ribs 7 and the rib storage groove 8 do not necessarily have to be formed.

[0022] If only ribs 7 are formed and rib storage grooves 8 are not formed, when multiple block paving reinforcement plates 1 are stacked vertically, a gap will be created between adjacent base plates 4 equal to the size of the ribs 7. However, in this invention, "base plates 4 are in approximate contact" includes not only cases where the base plates 4 are in contact with each other without any gaps, but also cases where there is a slight gap between the base plates 4, such that a gap is created between adjacent base plates 4 equal to the size of the ribs 7. Incidentally, notches 9 may be formed on the outer surface of the base plate 4 so that multiple reinforced block paving plates 1 can be stacked on top of each other and bundled together with rubber bands or the like.

[0023] When using the block pavement reinforcement plate 1 of the present invention, the block pavement reinforcement plate 1 is placed on the upper surface of the ground 2, as shown in Figures 7 and 8. The ground may be an unprocessed area, or a subgrade 10, filter layer 11, base course layer 12, and sand cushion layer 13 may be formed from below, and these structures may constitute the ground 2. In this embodiment, such a structure is used as the ground 2.

[0024] After placing the block paving reinforcement plate 1 on the top surface of the ground 2, the paving blocks 3 are placed so as to abut the joint boards 5, and joint sand 14 is filled into the joints G between the paving blocks 3.

[0025] [Different forms for carrying out the invention] Next, different embodiments for carrying out the present invention shown in Figures 9 to 13 will be described. In describing these different embodiments for carrying out the present invention, the same reference numerals are used for components identical to those in the first embodiment for carrying out the present invention, and redundant descriptions will be omitted. In the second embodiment for carrying out the present invention shown in Figures 9 to 11, the main difference from the first embodiment for carrying out the present invention is that a base plate 4A is made in which some of the multiple joint plate penetrations are formed in the shape of elongated holes and the others are formed in the shape of notches. Even if a reinforced plate 1A for block pavement using such a base plate 4A is made, the same effects and advantages as in the first embodiment for carrying out the present invention can be obtained.

[0026] In addition, in this embodiment, the notched joint plate penetration portion 6A is formed in such a shape that the joint plate 5 can pass through when the notched joint plate penetration portion 6A is slid in the direction of extension of the notched joint plate penetration portion 6A. When stacking the block paving reinforcement plates 1A, instead of rotating the base plate 4A to overlap them, the base plate 4A can be slid in the direction of extension of the notched joint plate penetration portion 6A, allowing the remaining joint plate 5 to pass through the elongated joint plate penetration portion 6 and overlap them.

[0027] In the third embodiment for carrying out the present invention shown in Figures 12 and 13, the main difference from the first embodiment for carrying out the present invention is the use of a base plate 4B having a joint plate penetration portion 6B formed by cutting out at least a part of the outer surface in a notched shape in a plan view. Even with a reinforced block pavement plate 1B using such a base plate 4B, the same effects and advantages as in the second embodiment for carrying out the present invention can be obtained, and it can be made lighter, thereby reducing transportation costs and the like.
