Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous joint block which is laid mainly on a portion where a large load is not applied, such as a sidewalk, a river bank, a slope of a constructed land.

[0002]

2. Description of the Related Art Conventionally, for example, when paving a sidewalk, block bodies are laid one by one on a base formed of gravel or sand at desired intervals, and joints are filled with a joint material such as sand. Or a block body having a fitting portion formed on the outer peripheral edge is laid so that the fitting portions adjacent to each other fit each other.

[0003]

However, in the case of the conventional block body and the method of construction described above, it is necessary to lay the block bodies horizontally while adjusting the joint spacing between adjacent block bodies one by one. It was a very time-consuming task. Moreover, since it is a work that requires skill, the laying work had to rely on a skilled engineer called a block builder. Moreover, the number of man-hours per unit area is large, the construction period is long, and the cost is high. In addition, the block bodies laid by the conventional construction method can be moved individually as each block body is individually placed on the sand adjustment layer in an independent state. It causes separation and sinks into pieces. Therefore, the unevenness that the pavement surface becomes uneven is likely to occur. Also,
There is a drawback that a gap is created between each block body and the adjustment layer, and each block becomes in an unstable state, the block body in an unstable state comes out, and the block body is lost. Therefore, the manager of the area had to frequently perform repair work. In particular,
When the conventional block is used for pavement on the sidewalk, the above-mentioned unevenness hinders the pedestrian's safe walking, and repair work is carried out even if the land is lost or the block comes off and is lost. The current situation is that they cannot catch up. In addition,
Simply connecting the locks with pins etc.
The pin-buried part of the hook is scratched by a temporary load.
Rubbing occurs, durability remains a problem, and flexible wire rods and
Just by connecting to the car with fiber materials, these connecting materials themselves
Repeatedly damages due to repeated load. Therefore, an object of the present invention is to provide a continuous joining block for laying, which is easy to construct and has excellent durability that does not cause unevenness.

DISCLOSURE OF THE INVENTION The present invention has been proposed in order to achieve the above object. According to a first aspect of the present invention, a concrete unit block is provided with a predetermined gap between adjacent unit blocks. A plurality of vacant spaces are formed, and adjacent connecting unit blocks are connected to each other by connecting members arranged so as to cross the gap to provide flexibility between the connecting blocks, and the connecting blocks are embedded in the body block of the connecting member.
A pull-out prevention part is provided on this part and
It is possible to swing the connecting member to the body block by covering the
It is a noh play. According to a second aspect of the present invention, in addition to the first aspect, a permeation coloring layer is formed on the surface of a single block.

[0005]

[Operation] Since the connecting members connect the adjacent single blocks to each other, when a load is applied to one single block,
The connecting member distributes this load to the adjacent single block to reduce the surface pressure applied to the base, and also prevents the single block from moving or separating, thereby preventing the occurrence of non-land. That
The connecting member can swing with respect to the single block.
Then, transfer the load to the adjacent single block without difficulty.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a continuous joining block 1 for installation according to the present invention, and FIG. 2 is a sectional view of the same.

The continuous joint block 1 according to the present invention comprises a plurality of unit blocks 2 ...
Are joined to each other and configured.

[0008] Each unit block 2 is formed by a so-called instant demolding method in which sand, cement, a little water, and a binder, which is mixed if necessary, are filled in a mold and compacted by pressing, and immediately demolded. Form. Also, single block 2
The colored layer 4 having an appropriate color or pattern is formed on the surface (upper surface) of the. The coloring layer 4 uses a so-called permeation coloring method in which a coloring liquid is applied to the inside of the mold in advance and the above-mentioned coloring pigment is permeated into the filled concrete particles to color the surface portion. Then, the mold is provided with appropriate irregularities that are modeled from an actual stone or imitate a stone, and the surface of the demolded single block 2 is combined with the above-mentioned permeation coloring to form the background of natural stone. To do so.

A continuous joining block 1 according to the present invention is formed by gathering a plurality of the single blocks 2 as described above with a connecting member 3 in a state in which a gap D is formed therebetween. Further, the outer edge of the single block 2 located on the outer side is formed into a substantially straight line so that the whole is formed into a substantially rectangular shape. For this reason,
A partition plate 5 is provided in a rectangular frame to form a recess for molding the single block 2 in an appropriate shape, and a connecting member mounting portion 6 for mounting the connecting member 3 is mounted at a desired position on the partition plate 5. Form. Since the continuous member 3 joins the adjacent single blocks 2 and 2 across the gap D between the single blocks 2, it is formed so as to cross the partition plate 5. Also, the formwork should be of a size and weight that can be carried by workers.
It has an inner size such that the finished size is, for example, about 900 mm × 600 mm. And the partition plate 5
Since the position is the gap D between the individual blocks 2, that is, the joint 7, the thickness (gap D) of the partition plate 5 is, for example, about 5 mm for a sidewalk.

Further, as described above, the single block 2 is provided on the bottom surface of the concave portion defined by the partition plate 5 in the mold.
The composite pigment liquid for forming the permeation coloring layer 4 is applied to the surface of the.

The connecting member 3 is mounted in the connecting member mounting portion 6, for example, the concave groove formed in the end surface of the partition plate 5, and the connecting member 3 is widened in the shape of a flange or a collar at both ends or in the vicinity of both ends. It is a long member provided with at least one set of the slip-out preventing portion 9. The connecting member 3 is made of a flexible synthetic resin such as vinyl, rubber, or a metallic material such as aluminum so as to provide appropriate flexibility between the individual blocks 2. . In addition, the slip-off prevention portion 9 is
Although one set is provided in the illustrated embodiment, a plurality of sets may be provided and the shape is not critical. When the portion embedded in the single block 2 is covered with sponge, the connecting member 3 can be slightly swung (swingable) with respect to the single block 2 after molding, and the connecting member 3 is caught by the slip-out preventing portion 9. Does not fall out of the single block 2. Therefore, the angle between the single block 2 and the connecting member 3 is likely to change, and the flexibility of the entire connecting block 1 is increased.

Then, the mold fitted with the connecting member 3 is filled with a raw material prepared by blending cement, sand or the like, pressed by the upper mold and shaken to compact it, and then demolded. As described above, when the immediate demolition method is used, a substantially rectangular standardized continuous joint block 1 is completed in a short time, and the continuous joint block 1 is composed of a plurality of unit blocks 2.
Are assembled together, and the individual blocks 2 are joined to each other by a connecting member 3. Moreover, the pigment penetrates into the surface layer portion of each single block 2 to form the coloring layer 4. Therefore, by adjusting the pigment, the hue of each single block 2 can be changed, or a blurring effect can be added within a single single block 2, and a single block 2 closer to natural stone can be created. . Also,
In the case of permeation coloring as described above, the pigment permeates only the surface layer portion, which is also useful for saving the pigment.

Next, a case of paving a sidewalk using the continuous joint block 1 according to the present invention formed as described above will be described.

First, rubble stones or the like are laid on the sidewalk to form the roadbed 10, and sand or small stones are laid on the upper surface of the roadbed 10 to 30 m.
The adjustment layer 11 having a thickness of about m is formed. The adjustment layer 11
Is formed flat.

Next, the continuous joint block 1 according to the present invention is laid on the upper surface of the adjusting layer 11. Since the continuous joint block 1 is formed in a substantially rectangular shape, the laying work can be performed simply by placing them side by side, which is extremely easy. Moreover, the continuous joint block 1 according to the present invention is 900 mm long and 600 mm wide.
When the thickness is about 60 mm and the thickness is about 60 mm, it can be configured to be a little less than 70 kg, so that it can be sufficiently handled by two workers and does not require a transport machine or the like.

After placing the continuous joint blocks 1 as described above, if sand is filled between the adjacent continuous joint blocks 1 and the gaps D between the individual unit blocks 2 constituting the continuous joint block 1, the sidewalks will be covered. Paving is complete. The sidewalk may have an inclined surface between itself and the roadway, and the boundary between the inclined surface and the flat portion is a curved surface. However, in the joint block 1 according to the present invention, the joint member 3 is a single block. Neck to two
A possible swing, so are configured to flex to impart flexibility between the single block 2,2, flex without difficulty along the curved state of the variable curved surface. Therefore, not only a flat surface but also a curved surface can be easily paved. In the pavement formed on such a curved surface, since each block is conventionally independent, it is easy for the unsteady state to occur. However, in the continuous joint block 1 according to the present invention, each single block 2 is connected to the connecting member 3.
Since it is joined by, it is less likely to cause unevenness and has excellent durability.

The sidewalk laid with the continuous joint block 1 according to the present invention as described above has not only the appearance that the surface is the same as natural stone, but also one single block 2
Even if a load is applied to the unit block 2 and the unit block 2 tries to sink, the load is dispersed because the unit block 2 is connected to the adjacent unit block 2 by the connecting member 3 , and the connecting member 3 is connected to the unit block 2. Against the neck
Since it can be swung, there is no
It doesn't make sense. Therefore, the pressure (surface pressure) applied to the adjustment layer 11 per unit area is reduced, and the flow of sand or the like forming the adjustment layer 11 can be suppressed, whereby the individual blocks 2 and the adjustment layer 11 are It is possible to prevent a gap from being generated between the two. Therefore, the pavement surface on which the continuous joint block 1 according to the present invention is laid does not cause unevenness even after a long period of time, and has excellent durability. Also,
Since no terrain occurs, walking is easy and pedestrians can walk safely.

Further, as shown in FIG. 5, the adjustment layer 11 should be washed away by rainwater or the like, and the single block 2
Even if a gap G is formed between the lower surface of the and the adjustment layer 11,
When a load such as the weight of a pedestrian is applied on the single block 2, the single block 2 is supported by the connecting member 3 by being connected to the adjacent single block 2.
There is no possibility that the single block 2 is sunk by itself and becomes inferior. Therefore, it is safe, and since the single block 2 does not come off, there is no fear of loss.

On the other hand, in the case of the conventional block body 21, as shown in FIG. 6, when the adjustment layer is washed away by rainwater or the like and a gap is formed between the lower surface of the block body 21 and the adjustment layer. When the weight of a pedestrian is applied to the block body 21, the block body 21 sinks, which is dangerous. Further, when the block body 21 sinks, the sand of the adjustment layer flows to cause further unevenness.
Finally comes off and is lost.

Further, according to the continuous joint block 1 as described above, it is not necessary to lay small blocks one by one while adjusting the gap D, unlike the conventional case, during construction. Therefore, since no labor is required and no special skill is required, it is possible to lay it even by ordinary workers, and it is possible to shorten the construction period and reduce the cost.

Furthermore, since it is possible to provide a natural stone-like block without using natural stone, it is possible to prevent natural destruction due to the mining of natural stone and provide an environment close to nature, and to meet the demands of the times. You can

On the other hand, the continuous joint block 1 according to the present invention has water permeability. That is, since the gaps D having a predetermined interval are provided between the individual unit blocks 2, rainwater can enter through the gaps D. Therefore, when this continuous joining block 1 is used, rainwater can enter the ground, no water pool is formed, and it is easy to walk even in the rain. Moreover, since rainwater can be returned to the ground, it is effective for the growth of plants such as roadside trees and contributes to the conservation of nature. In addition, single block 2
It is also possible to impart water permeability to the single block 2 itself by adjusting the raw materials such as the grain size and bonding of the sand forming the.

In the above-mentioned embodiment, the case where the continuous joint block 1 is applied to a flat sidewalk has been described. However, the continuous joint block 1 according to the present invention is not limited to the sidewalk, but is also a river bank or a slope of a land. It is also possible to apply to such.

[0024] For example, bank protection, not only flat portions, but has a curved surface which is uneven, connective block 1 according to the present invention has connecting member 3 has flexibility, moreover articulated
Since the member 3 can be swung with respect to the single block 2, each single block 2 can be installed without difficulty along the curved surface, and the single block 2 can be fitted to the curved surface. Further, as described above, since it has water permeability, it can prevent the outflow of earth and sand in an environment close to nature when applied to a revetment. It is also possible to germinate and grow plants from the gap D between the single blocks 2.
It can also contribute to nature conservation and restoration. Therefore, the continuous joint block 1 according to the present invention has a wide range of application and an extremely high practical value.

Although the present invention has been described with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and may be implemented with appropriate modifications without departing from the configuration described in the claims. it can. For example, the shape of a single block can be set arbitrarily, and in the illustrated embodiment, the shapes are irregular, but it is also possible to repeat the single block as a single block.

Further, in the illustrated embodiment, the outer end edge is made straight and one continuous joint block is set to a rectangular shape, but the present invention is not limited to this, and the adjacent continuous joint blocks in a laid state. You may make it the complementary shape of unevenness which can be combined with the outer edge shape of. That is, the convex edge of one continuous joint block enters the concave edge of the adjacent continuous joint block, and the convex edge of the adjacent continuous joint block enters the concave edge of one continuous joint block. You may make it a complementary shape combined. Note that there may be a plurality of irregularities formed on one side.

[0027]

As described above, according to the present invention, a plurality of concrete unit blocks are formed with a predetermined gap between adjacent unit blocks, and the connecting member is arranged so as to cross the gap. Since the adjacent single blocks are connected to each other to give flexibility between the single blocks, no trouble is required during construction and no skill is required. Therefore, even a general worker can lay it very easily, and the construction period and cost can be reduced. Further, since the individual blocks are connected to each other, they do not separate and do not cause unsteadiness even after a long period of time. Therefore, it is possible to provide a laying block having high durability. Further, since the single blocks are connected, there is no possibility that only one block will be disconnected and lost. In addition,
