Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting block in which a plurality of blocks laid on a sidewalk or the like are connected by connecting members.

[0002]

2. Description of the Related Art Conventionally, blocks formed of, for example, natural stones, artificial stones, or bricks have been laid on sidewalks and parks in order to improve aesthetics (design). In this laying work, a connecting block in which a plurality of blocks are connected in advance by a string-like connecting member having flexibility is used in order to improve the workability. This connecting block is manufactured by bonding the connecting member to an outer surface (for example, a back surface side) of each block with a resin or the like. According to the connection block, a plurality of blocks can be handled as an aggregate of blocks, and a plurality of blocks can be laid at once, thereby improving workability.

[0003]

In the conventional connecting block, the adjacent blocks are connected at a predetermined connecting interval by a flexible string-like connecting member. Movement of the adjacent block in the contact / separation direction by the connection interval is allowed. For this reason, the entire size of the connection block is made expandable and contractable in accordance with the connection interval. On the other hand, when the connection block is laid on the laying surface due to the excessive degree of freedom of each block, the distance between the blocks is small. It is difficult to lay them with uniform connection intervals. Therefore, the worker
In order to make the connection intervals between the blocks uniform, once the connection blocks are disposed on the laying surface, the arrangement of the blocks must be adjusted, and the operation is complicated.

Therefore, instead of the above-described flexible string-shaped connecting member, a small-diameter metal wire (for example,
A connection block has been proposed in which a net-like connection member made of a 0.5 mm wire) is adhered to the outer surface (for example, the back surface side) of each block. According to such a connecting block, the movement of the adjacent blocks in the contact / separation direction is restricted, so that the connecting block can be laid with a uniform connection interval between the blocks, and the workability thereof can be improved. Can be improved.

However, when a small-diameter metal wire is used as the connecting member, the pressing force of the connecting member against the bonding surface (adhesive layer) based on the weight of the connecting block during transportation of the connecting block increases. There is a possibility that the bonding surface may be broken by the connecting member. In such a case, there is a problem that the connection member comes off from the adhesive surface, the connection state of each block is canceled, and the workability as the connection block cannot be maintained. Therefore, in order to solve such a problem, for example, a large-diameter connecting member (for example, a wire of 2 mm to 3 mm) is used.
However, in this case, the degree of freedom of each block is lost, and the state of the laying surface that can be laid (for example, a flat surface) is limited. That is, it becomes impossible to lay the connecting block along, for example, an undulating laying surface.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems existing in the prior art, and has as its object to flexibly adjust the state of the laying surface while maintaining the workability of the laying work. An object of the present invention is to provide a connection block that can be used.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a connecting block embodying the present invention; FIG.

First, the specific structure of the connecting block 10 will be described with reference to FIGS. 1 to 3. FIG. 1 schematically shows the appearance of the connecting block 10. As shown in FIG. In FIG. 1, the connection block 10 includes a plurality of substantially rectangular parallelepiped blocks 11 arranged in a line at predetermined connection intervals in the vertical and horizontal directions A and B, and a net-like shape on the back side of each block 11. It has a configuration in which (net-shaped) connecting members 12 are bonded and connected. Further, the connecting block 10 is an aggregate composed of a total of 20 blocks 11 in four rows (four) in the vertical direction A and five rows (five) in the horizontal direction B. Is a rectangular parallelepiped having an approximately rectangular outer shape. The surface of the connection block 10 (block 11) is a surface that can be visually recognized by a person after the connection block 10 is laid, and the rear surface means a surface opposite to the surface.

Each of the blocks 11 is formed by molding natural stone into a desired shape, and the front and back surfaces thereof are formed into a substantially rectangular shape and have a desired thickness. Each of the blocks 11 is formed such that the width and thickness in the vertical direction A are substantially the same between the blocks 11 and the widths in the horizontal direction B between the blocks 11 are different. That is, each block 11 of the present embodiment is formed as a plurality of types of blocks 11 having different sizes. The surface of each of the blocks 11 may be a design surface on which a pattern (not shown) is applied and glossy processing is performed,
The surface which has not been subjected to any processing to give a natural texture may be used.

The connecting member 12 includes a plurality of small-diameter (for example, 0.5 mm to 1.0 mm) metal wires (for example, wires, piano wires, etc.) 12a and 12 having elasticity.
b is a net-like (net-like) member (a so-called steel net) arranged in a crossing manner in the extending direction corresponding to the vertical and horizontal directions A and B. The metal wire 1
If the diameter of 2a, 12b is too small, the strength of the connecting block 10 against its own weight is low, and there is a possibility that the connecting block 10 will break during transportation. Would. In this embodiment,
The surfaces of the metal wires 12a and 12b are plated with zinc to prevent rust.

The two metal wires 12a, 12b
Are welded to the intersection S formed at the intersection of the two metal wires 12a and 12b. The two metal wires 12a and 12b are arranged at substantially equal intervals in the vertical and horizontal directions A and B, respectively, and a mesh of the connecting member 12 formed by the two metal wires 12a and 12b is provided. Are approximately square. The size of the mesh of the connecting member 12 is sufficiently smaller than the width of each block 11 in the vertical and horizontal directions A and B.

Therefore, a plurality of metal wires 12a and 12b are provided on the back side of each block 11 in the vertical and horizontal directions A,
B are arranged at predetermined intervals. In the present embodiment, approximately five metal wires 12a are arranged in the vertical direction A with respect to the back side of each block 11 and approximately three to nine metal wires 12 are arranged in the horizontal direction B according to the width of each block 11. The wire rod 12b is arranged. The connecting member 12
Has rigidity compared to, for example, a rubber member, a string member made of a thread material, a vinyl member, or the like, and has such a rigidity (elasticity) that it can be bent without requiring tools or machinery. Is a member having.

The connecting member 12 has such a strength that the connecting block 10 is not broken by its own weight when the connecting block 10 is carried (for example, when two workers carry it while holding both ends). are doing. Further, the connecting member 12 is a member that can be cut by a cutting tool such as a knife or iron scissors. And the connecting block 10
The worker can arbitrarily change the size (shape, arrangement pattern) of the connection block 10 according to the size (area) of the laying surface of the connection block.

The connecting member 12 located on the back side of each block 11 is covered at least partially with a covering cloth 13 as a covering member in the form of a net. The covering cloth 13 has permeability and is formed (cut) into a desired size in accordance with the size of each block 11. That is, the covering cloth 13 is formed smaller than the area of the back surface (front surface) of each of the blocks 11, and the size of the mesh is smaller than the mesh of the connecting member (for example, about 1/4). Has become. The covering cloth 13 is connected to the connecting member 1.
2 protects the adhesive layer 14 so as to prevent the adhesive layer 14 from being broken and falling off.

As shown in FIG. 3, the connecting member 12 is provided on the back side of each block 11 so as to cover the covering cloth 1.
3 is adhered with a resin or the like in a state of covering.
On the back side of each block 11, an adhesive layer 14 for adhering and fixing the connecting member 12 and the covering cloth 13 together is formed. The covering cloth 13 is impregnated with the resin forming the adhesive layer 14 by being permeable, and is adhered to the back surface of each block 11 together with the connecting member 12. The connection member 12 is bonded to the back surface of each block 11 in a state where the connection member 12 is sandwiched between the back surface and the covering cloth 13.
Further, the connection member 12 is bonded to the back surface of each block 11 together with the covering cloth 13, so that the bonding strength is secured.

Therefore, the connecting block 10 thus configured has a plurality of metal wires 12a and 12b disposed on the back surface side of each block 11, so that the adjacent blocks 11 are connected to each other. Release direction (vertical and horizontal directions A,
Movement to B) is regulated. Therefore, the connection interval between the blocks 11 is maintained at a desired interval in the vertical and horizontal directions A and B. On the other hand, the connecting block 1
0 indicates that each block 11 is allowed to bend in the thickness direction (vertical direction) by the elastic force of the connecting member 12.

Next, an example of a method of manufacturing the connecting block 10 will be described with reference to FIG. First, a transparent sheet material 16 is arranged on a base 15 on which the arrangement positions of the blocks 11 are indicated. The sheet material 16
Is provided to peel off the connection block 10 from the base 15 after the connection block 10 is completed. Then, each block 11 is placed on the sheet material 16.
The covering cloth 13 formed into a desired size based on the disposition position is disposed (see FIG. 4A).

Next, the adhesive layer 1 is formed on each of the covering cloths 13.
The molten resin 17 for forming 4 is sprayed. Then, in this state, the connecting member 12 is connected to the base 1.
5 (see FIG. 4B). Thereafter, a predetermined number (20 in the present embodiment) of the blocks 11 is arranged based on the arrangement position of the blocks 11 shown on the upper surface of the base 15 (see FIG. 4C).

When the resin 17 is dried and solidified,
The adhesive layer 14 is formed on the back side of each of the blocks 11, and the connecting member 12 is formed by the adhesive layer 14.
Then, the covering cloth 13 is bonded and fixed. Then, the base 1
The connection block 10 shown in FIG. 1 is completed by peeling the connection block 10 from 5 (sheet material 16).

The method of manufacturing the connecting block 10 can be changed as appropriate. For example, the resin 17 may be sprayed on the connecting member 12 and the covering cloth 13 arranged on the base 15 to arrange the respective blocks 11, or the resin 17 may be applied on the back side of the connecting member 12 and the covering cloth 13. Each sprayed block 11 may be arranged. Further, the resin 17 may be sprayed in a state where the blocks 11, the connecting members 12, and the covering cloth 13 are stacked.

Next, a working mode for laying the connecting block 10 manufactured as described above on a laying surface will be described. First, the laying surface is filled with mortar for fixing the connection block 10, and the block 10 is placed on the mortar, for example, with two workers holding both ends. At this time, since the movement of the connection blocks 10 in the direction of contact and separation between the blocks 11 is restricted by the connection members 12, the connection blocks 10 are arranged with a uniform connection interval between the blocks 11. When the connecting block 10 is laid on the undulating laying surface, the connecting block 10 is arranged while being bent along the state of the laying surface based on the elastic force of the connecting member 12.

A part of the mortar filled in the laying surface is reduced by the weight of the connection block 10 or the pressure of the connection block 10 through the mesh of the connection member 12 located within the connection space of the connection block 10. Is filled in. Thereafter, the joint mortar is further filled within the connection interval to complete the work of laying the connection block 10.

Therefore, according to the present embodiment, the following effects can be obtained. (1) The connecting member 12 is adhered to the back surface of each block 11 in a state where the covering cloth 13 is covered. Therefore, it is possible to prevent the connection member 12 from breaking the adhesive layer 14 and dropping off when the connection block 10 is carried, and the connection state of the blocks 11 can be maintained. Therefore, it is possible to provide the connection block 10 in which the movement of the blocks 11 in the contact and separation directions is restricted by using the small-diameter connection member 12, and the workability of the laying operation can be maintained.

(2) Since the connecting member 12 has elasticity, it can flexibly respond to the state of the laying surface. For example, the connecting block 10 can be mounted on an undulating laying surface.
Can be laid easily.

(3) A plurality of metal wires 12a and 12b are arranged on the back side of each block 11. Therefore, it is possible to reliably restrict the movement of the blocks 11 in the contact / separation direction.

(4) The connecting member 12 is formed in a mesh shape where the two metal wires 12a and 12b intersect. Therefore, the handling of the connecting member 12 is facilitated, and the work of arranging the connecting member 12 at the time of manufacturing the connecting block 10 can be facilitated.

(5) The two metal wires 12a, 1
2b is welded to each other at a point of intersection S by spot welding. Therefore, even if the metal wires 12a, 12b are arranged within the connection interval between the blocks 11, the metal wires 12a, 12b can be prevented from separating. Therefore, the positioning work accompanying the arrangement of the connection member 12 can be easily performed at the time of manufacturing the connection block 10.

(6) The connecting member 12 is a cuttable member. Therefore, an operator can easily change the size (shape, arrangement pattern) of the connection block 10 easily according to the size (area) of the laying surface at the site where the connection block 10 is laid. In addition, it is not necessary to manufacture the connection block 10 according to the size (shape) of the laying surface in advance, which can contribute to a reduction in manufacturing cost.

(7) The covering cloth 13 is a member having permeability. For this reason, the resin is impregnated into the covering cloth 13, and the connecting member 12 and the covering cloth 13 can be firmly adhered and fixed to the back surface side of each block 11 as compared with a case where the covering cloth 13 does not have permeability. it can.

(8) The mesh size of the connecting member 12 is larger than the mesh size of the covering cloth 13. Therefore, the mortar filled on the laying surface can be filled from the mesh of the connection member 12 into the connection interval between the blocks 11. Further, by making the mesh of the coating cloth 13 finer, the coating cloth 13 can be impregnated with more resin, and the back surface of each of the blocks 11 can be reliably formed in a state where the connecting member 12 is covered with the coating cloth 13. Can be glued to the side.

(9) The connecting member 12 and the covering cloth 13
Are adhered to the back side of each block 11 by resin. Therefore, the manufacturing operation is facilitated, which can contribute to a reduction in manufacturing cost. The connecting member 12
The block 11 cut by the cutting of the connecting member 12 is melted by a resin that forms the adhesive layer 14 to form the connecting member 12.
The coating cloth 13 can be peeled off, and can be reused when a new connection block 10 is manufactured.

The present embodiment may be modified as follows. In the above-described embodiment, the connecting member 12 formed in a net shape is used, but as shown in FIG.
A plurality of independent metal wires 12
a and 12b may be arranged in the extending direction and adhered in a state where the covering cloth 13 is covered. In FIG. 5A, three metal wires 12a and 12b are arranged on the back side of the block 11. The intersection formed at the intersection of the metal wires 12a and 12b may or may not be joined. In this case, the two metal wires 12a and 12b are arranged so that the intersection is located in the adhesive layer 14, or the two metal wires 12a are formed by forming the adhesive layer 14.

In this case, a plurality of independent metal wires 12a and 12b may be used in place of the mesh-like connecting member 12.

In the above embodiment, the connecting member 12 is directly adhered to the back side of each block 11, but as shown in FIG. 5C, the connecting member 12 is connected to the back side of each block 11. A groove 18 having substantially the same shape as that of the member 12 may be formed, and the connecting member 12 may be bonded in a state where the connecting member 12 is disposed inside the groove 18. In this case, also in this case, the connecting member 12 is adhered while covering the covering cloth 13. With such a configuration, the thickness of the adhesive layer 14 can be increased, and the connection member 12 can be more securely bonded.

In the above embodiment, the connecting blocks 10 are composed of four blocks in the vertical direction A and five blocks in the horizontal direction B, that is, a total of 20 blocks 11.

However, a connecting member in which a resin wire is formed in a net shape is adhered to the back side of each of the blocks 11 to form a connecting block. 10 may be configured. Further, the two metal wires 12a and 12b shown in FIG.
Instead, a plurality of independent resin wires may be used as the connecting member.

In the above embodiment, the material of the covering cloth 13 is not particularly described, but the material of the covering cloth 13 is not particularly limited as long as it has permeability. For example, the covering cloth 13 made of a cloth material such as gauze or a component dissolving resin may be used. The covering cloth 13
May be a member having no permeability.

In the above embodiment, the adhesive layer 14 is formed of a resin, but the adhesive layer 14 may be formed of an adhesive instead of the resin. Further, the coating cloth 13 is
Each block 1 may be replaced with an adhesive member such as a tape or a pin, for example, instead of being fixed with resin or an adhesive.
1 may be fixed to the back side.

In the above-described embodiment, the two metal wires 12a, 12b are formed so that the mesh of the connecting member 12 is substantially square.
Although the wires 12b are arranged in a cross shape, the two metal wires 12a and 12b may be crossed obliquely so as to form the mesh in a diamond shape. In the case of the connecting member configured as described above, the two metal wires 12a and 12b are arranged obliquely with respect to the back surface of each block 11. Further, either one of the metal wires 12a and 12b may be arranged obliquely.
