The following describes embodiments of the present invention with reference to the drawings.

(First Embodiment)

As shown in Figs. 1 to 3, the paving block connecting member A according to the first embodiment of the present invention has a horizontally long, octagonal horizontal plate 1 that is horizontally long in plan view, and the horizontal plate 1 It is placed on the upper surface of) and has a vertical plate (2) of one shape in plan view. The paving block connection member (A) consists of a horizontal plate (1) and a vertical plate (2) in a T-shape viewed from the side.

The corner inclined part 3 which forms the inclined surface which connects the horizontal board 1 and the vertical board 2 is provided in the corner created by the horizontal board 1 and the vertical board 2. The corner inclined portion 3 is wide in the vicinity of the center and narrow in width along both ends to form a horizontal cross section in an arc shape. The corner inclined portion 3 is provided on both sides with the vertical plate 2 interposed therebetween.

The connection between the horizontal plate 1 and the vertical plate 2 is secured by the corner inclined portion 3, so that the strength of the paving block connecting member A can be increased. This makes it possible to firmly connect the paving blocks.

In the vertical plate 2 and the corner inclined portion 3, a plurality of sand filling grooves 4 are formed at intervals from the upper edge of the vertical plate 2 to the horizontal plate 1. As a result, the vertical plate 2 is convex in plan view, and the joint sand filling groove 4 constituting the concave portion is inclined at the corner inclined portion 3 vertically at the vertical plate 2 so as to be horizontal. Connected to.

Several dome-shaped positioning protrusions 5 are formed in the vicinity of the outer peripheral edge of the upper surface of the horizontal plate 1, and the positioning protrusions 5 are arranged radially from the center of the horizontal plate 1.

The paving block connecting member A having such a shape is formed of a relatively high rigidity synthetic resin or iron or other metal.

On the other hand, the paving block (X) laid using the paving block connecting member (A) is a rectangular plate-like block in plan view as shown in FIG. Protrusions 20 are formed on the side of the paving block X, so that the protrusions 20 are in contact with the side of the paving block X adjacent to each other so that the width of the joint can be kept constant.

On the pavement surface, this paving block (X) is laid out in a so-called barrel (imemoji) shape in which the horizontal and vertical joints are arranged in a lattice shape.

Coupling grooves 10 are formed at positions where the heights on the upper surface of the paving block X are constant at sides and corners of the paving block X adjacent to each other.

As shown in Fig. 4, the coupling groove 10 is formed horizontally on the side surface of the paving block X and has an arc shape in plan view. The thickness is almost the same as the thickness of the horizontal plate 1 and the positioning projection 5 of the paving block connecting member A combined.

The height position of the coupling groove 10 is preferably about 2/3 of the thickness of the paving block X on the upper surface of the paving block X. If the position is at this position, even if a crack occurs in the side portion or the corner of the paving block (X) due to the grooving of the coupling groove (10) is because it hardly affects the finished surface.

Moreover, the taper 11 which spreads toward the opening side is formed in the upper edge of the opening part of the coupling groove 10. The taper 11 is formed in a horizontal cross section so as to face the corner inclined portion 3 at a predetermined interval when the paving block connecting member A is inserted.

The engaging groove 10 may be processed with a disc grinder provided with a whetstone of disc shape. By forming the disc-shaped grindstone thickness by combining the horizontal plate 1 and the positioning projection 5 together, the arc-shaped engaging groove 10 according to the grindstone diameter can be easily processed by one groove cutting operation. The taper 11 may be processed, for example, by a grinder having a conical whetstone. Moreover, you may use the grinding wheel of the exclusive shape which can process the engaging groove 10 and the taper 11 simultaneously.

Next, the construction method of the paving block X using the paving block connection member A is demonstrated.

(1) Connection of paving block (X)

Neighboring paving block (X) is connected to each other by fitting the horizontal plate (1) of the paving block connecting member (A) in the coupling groove (10).

At this time, since the positioning protrusion 5 is dome-shaped, it is easy to insert the paving block connecting member A without being caught by the coupling groove 10.

In addition, since the positioning protrusion 5 contacts the coupling groove 10, the horizontal plate 1 does not move up and down inside the coupling groove 10. Therefore, even in the next step of filling the joint sand in the next step, it is possible to suppress the vertical movement of the neighboring paving block (X) to prevent the step in the joint.

By connecting in this way, while the height of the paving block (X) is matched, the fluctuation in the vertical direction is limited, so that a step in the joint may not be generated.

Further, even when the vertical plate 2 is sandwiched between neighboring paving blocks X, the width of the joint can be kept constant even when there is no protrusion 20 in the paving block X.

At this time, the convex portion of the vertical plate 2 is in contact with the side surface of the paving block X to define the width of the joint, and the joint sand filling groove 4, which is a concave portion, is opened. That is, the vertical plate 2 forms a gap between the sides of the paving block X while defining the width of the joint.

At the time of connection, the paving block connecting member A is inserted into the side and corners of the paving block X positioned first, and the paving block X adjacent thereto is aligned. At this time, the pavement block X to be fitted later is inclined from the top, but is attached to the pavement block connecting member A, but the taper 11 is formed so that the horizontal plate 1 is smoothly inserted without being caught in the upper edge of the opening.

In addition, when positioning while wrapping the paving block X, the bottom of the paving block X attracts a little bit of sand on the paving surface, but the paving block X has its bottom periphery 12 camouflaged. Because it is configured to be a refuge of sand, it is possible to prevent the occurrence of irregularities caused by the joint sand dragged.

(2) Charge of joint (meji) sand

After the paving block X is connected, sand containing a hardener is introduced at the joint between the paving blocks X adjacent to each other. As the solidifying agent, re-emulsified emulsion powders such as polyvinyl alcohol, vinyl acetate-beoba copolymer resin, cement, and the like are used.

Joint sand introduced into the joint as shown by the arrow shown in Figure 4 passes through the joint sand filling groove (4) formed in the vertical plate (2) and the corner inclined portion (3) paving block connecting member (A) and the coupling groove (10) Filled in the gap between

At this time, the gap between the taper 11 and the paving block connecting member (A) is made constant by the corner inclined portion (3), so that the sand flows smoothly, and the inside of the corner formed by the horizontal plate (1) and the vertical plate (2) You can prevent the air from accumulating.

In addition, since the horizontal section of the corner inclined portion (3) is arcuate and the positioning protrusions (5) are radially arranged, the sand can be radially widened, and the joint sand is combined with the paving block connecting member (A) and the coupling groove (10). Can make every corner evenly insane.

(3) solidification of joint sand

As shown in FIG. 5, when the filled joint sand is solidified, the gap between the paving block connecting member A and the paving block X disappears, and the effect of suppressing the step in the joint can be further enhanced. As a result, a load is applied and the paving block (X) can be prevented from settling to prevent a step in the joint.

In addition, when the joint sand is solidified, the positioning protrusions 5 may be caught by the joint sand to firmly connect the paving blocks X adjacent to each other.

As described above, the paving block X may be laid as shown in FIG. 6.

In addition, you may use joint sand which does not contain solidifying agent. Also in this case, filling the joint sand in the gap between the paving block connecting member A and the paving block X can increase the step suppression effect at the joint. However, the joint sand including the hardening agent is preferable because the connection of the paving block (X) is stronger and the effect of suppressing the step is increased.

(Second Embodiment)

As shown in Fig. 7, the paving block connecting member B according to the second embodiment of the present invention has a sand filling groove formed by a joint only in the vertical plate 2 in the paving block connecting member A according to the first embodiment. 4) is formed, and the positioning projection 5 is wedge shaped. Since the other structure is the same as that of 1st Embodiment, the same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

In this embodiment, although the joint sand filling groove 4 is not formed in the corner inclination part 3, when the clearance gap between the taper 11 and the corner inclination part 3 which were formed in the paving block X is wide, this gap is provided. Since the joint sand may flow into the joint, the joint sand may be filled in the gap between the paving block connecting member B and the coupling groove 10.

The positioning projection 5 is formed toward the direction away from the vertical plate 2 of the V-shaped tip. The thickness is made thinner toward the front end and thicker toward the rear end, and the rear end is composed of a plane perpendicular to the horizontal plate (1). That is, it is easy to insert the horizontal plate 1 in the coupling groove 10 is inclined, but the reverse is made to hang.

In addition, when the charged joint sand is solidified, the positioning protrusions 5 may be caught by the joint sand to firmly connect neighboring paving blocks X to each other.

In the present embodiment, the paving block X can be constructed in the same manner as in the first embodiment, the step restraining effect in the joint can be enhanced, and the paving block X sinks due to the load, and a step in the joint occurs. Can be prevented.

(Other Embodiments)

In the above embodiment, the joint sand filling groove 4 is formed in the vertical plate 2 and the corner inclined portion 3 to enable the filling of the joint sand. However, the present invention is not limited thereto, and a gap is formed between the paving blocks X. It can be formed to have a structure that passes through the joint sand.

For example, as shown in Fig. 8, the vertical plate 2 may be formed in a comb shape. In this case, the comb teeth contact the side surface of the paving block X to define the joint width, and the cutout groove 6 of the comb forms a gap between the paving block X and the paving block X. Therefore, the joint sand can be filled through this incision groove portion 6. In addition, the cutting groove 6 is formed to a height through which the taper 11 passes through the joint sand.

Alternatively, as shown in FIG. 9, the projections 7 may be provided on the vertical plate 2. The projections 7 provided on both sides of the vertical plate 2 are in contact with the side surface of the paving block X, so that a gap is formed between the vertical plate 2 and the paving block X, and the joint sand can be filled in the gap.

10, the thickness of the vertical plate 2 may be made thinner than the joint width. In this case, the joint width is kept constant by the protrusions 20 of the paving block X. A gap is formed between the vertical plate 2 and the paving block X so that the joint sand can be filled in the gap .

The effect of suppressing a step | step can be heightened by filling joint sand like 1st Embodiment in the shape mentioned above.

The horizontal plate 1 of the paving block connecting member may have any shape as long as it has a suitable margin with respect to the coupling groove 10 formed in an arc shape in plan view and is inserted in a state where it is not easily deflected. For example, as shown in FIG. 10, a circle (a), an ellipse (b), a rounded rectangle (c), and a polygon (d) may be mentioned. Regarding the rounded rectangle shown in (c), it is preferable that the corner portion (R) is at least about 1/4 of the length of the side. As for the polygon of (d), for example, a balanced polygon having a hexagon or more such as a regular octagon is practical. Shapes without square edges can also be regarded as octagons. (R) may be formed in the corner part of a polygon. Any planar shape consisting of line symmetry or point symmetry is easy to process, and the vertical plate 2 can be arranged in a balanced manner, which is very suitable.

The vertical plate 2 is not limited to the flat shape b in a plan view, but may be constituted by (a), a T shape (c), and a cross shape (d). The straight shape (b) is used to connect the sides of the paving block. The three-pronged trident shape (a) is used at the corner where three paving blocks converge. The T shape (c) is used for the so-called closed joints. The cross (d) is used at the corner where four paving blocks are collected. In addition, the shape of the vertical plate 2 can be arbitrarily selected according to a place to insert the paving block connecting member.

As shown in Fig. 12, the vertical plate 2 may be provided on the upper and lower surfaces of the horizontal plate 1 symmetrically with the horizontal plate 1 interposed therebetween (e). By doing so, the joint width can be kept constant even by the vertical plate 2 on the bottom surface. Further, the corner inclined portion 3 may be provided inside the corner formed by the vertical plate 2 and the horizontal plate 1 of the bottom face (f). At this time, if the height of the vertical plate 2 of the upper surface and the height of the vertical plate 2 of the lower surface are equal, it can be used regardless of the up-down direction in the field, and the workability is improved. In addition, the joint sand filling groove 4 is sufficient to be formed in the vertical plate 2 and the corner inclined portion 3 of the upper surface.

 In addition, in (f), the height of the vertical plate 2 of the upper surface may be made low and may be set to the same height as the corner inclination part 3 (g). In this case, even if the joint sand filling groove 4 is not formed in the vertical plate 2, the joint sand filling groove 4 can be filled if the joint sand filling groove 4 is formed in the corner inclined portion 3. In addition, the vertical plate 2 may be provided only on the bottom surface of the horizontal plate 1 without providing the vertical plate 2 on the upper surface of the horizontal plate 1 (h). In this case, since there is nothing blocking the joint above the horizontal board 1, sand can be filled in joint.

The inclined portion 3 inside the corner can increase the strength of the paving block connecting member and is not limited as long as it can smoothly flow the joint sand, and is not limited to the flat shape from the side (see FIG. 3). It may be configured in a curved shape (i).
