Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for use in parking lots, park squares, emergency vehicle approach roads, etc., and does not cause block jumps or lateral displacements, and has a green construction road surface structure excellent in workability. Regarding the construction method.

[0002]

2. Description of the Related Art Conventionally, as a method of constructing a green road surface used for a parking lot or the like, a large number of holes having an upper opening are formed on an upper surface of a block having a relatively large area, and each of the holes is filled with soil. A method of vegetating plants on this medium is known. There is also known a method in which a large number of blocks are laid with joints spread, the joints are filled with soil, and plants are vegetated on the soil. Various spacers for securing joints have also been proposed.

[0003]

However, in the conventional method using a block having a large number of holes formed on the upper surface, the roots of plants such as turf cannot grow in the horizontal direction, so that the plants wither immediately. There was a disadvantage that it would.
In addition, although the method of laying the blocks with the joints widened allows the plants to grow efficiently, the construction is extremely troublesome, and furthermore, the blocks jump up due to the running of the vehicle, etc. There were drawbacks. In particular, when a large jumping stress and a lateral displacement stress are applied when the vehicle is suddenly stopped or suddenly started, the block is likely to jump up or laterally shift. In addition, the use of various spacers exerts a restraining force on a slight lateral displacement, but hardly has a restraining force particularly on a block jumping up. Therefore, the present invention, the running of the vehicle, sudden stop, even when the block jumps up or without lateral displacement,
An object of the present invention is to provide a greened road surface structure having excellent workability.

[0004]

Means for Solving the Problems The present invention has been proposed in view of the above, and a large number of concrete blocks are vertically and horizontally formed on a construction surface by a large number of reinforcing members arranged in a form beforehand at the time of making the blocks. A concrete product integrally connected at predetermined intervals between adjacent blocks (front, rear, left and right) is laid, and joints between the blocks are filled with soil and plants are vegetated on the soil. The present invention relates to a greened road surface structure and a construction method thereof.

A spacer thinner than the block may be inserted between the blocks, or a block integrally provided with a spacer thinner than the block below the side surface of the block may be used.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A concrete product used in the present invention comprises a large number of concrete blocks and a large number of reinforcing bars connecting them together as described above. No restrictions. That is, the concrete block may be a block made of ordinary concrete, or a block made of porous concrete formed by connecting aggregates with a small amount of a binder to form continuous fine voids. A void may be formed. In this case, there is no limitation on the type of aggregate, aggregate cement ratio, water cement ratio, and the like. Or, only the surface layer is porous concrete,
Otherwise, it may be a composite that is usually concrete. In addition, since the road surface structure is intended for greening, the smaller the concrete block is, the better the greening is, and the wider the joint interval is, the better. However, as for the road surface that bears the load of the vehicle, it is desirable that the size and the joint interval of the concrete block are appropriately set according to the tire width of the vehicle. Specifically, one side or diameter of the concrete block is preferably about 10 cm at a minimum and about 30 cm at a maximum, and if it is smaller than this range, the load from the tire of the passenger car is concentrated on one concrete block, and from this range. If it is large, the landscape of the green road surface will be impaired. Also,
The minimum thickness of the concrete block is about 5cm,
A maximum of about 15 cm is desirable. If it is thinner than this range, it is easy to break, and if it is thicker than this range, workability deteriorates. Further, the joint interval is preferably about 5 cm at a minimum and about 15 cm at a maximum, and if it is smaller than this range, the scenery of the green road surface is impaired. Becomes
In addition, as a reinforcing material, generally, a reinforcing bar is widely used,
The material is not particularly limited to this, and any material or any surface-treated material may be used.

There is no particular limitation on the spacer used in the present invention, as long as it is thinner than the blocks constituting the concrete product. In particular, in a mode in which the spacer is fitted between the blocks, when the side surface of the block constituting the concrete product is inclined so as to expand downward and outward, the side surface of the spacer is inclined so as to narrow downward and inward. Since the spacer is wedge-shaped between the joints, the force of suppressing the jumping and lateral displacement becomes stronger than when a simple spacer is used. In a mode in which the spacer is integrally provided on the block itself (below the side surface) of the concrete product, there is an advantage that it is not necessary to transport and manage the spacer as a separate member. It exerts a greater suppressing force than it suppresses a jump or lateral displacement.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. The concrete product 1 shown in FIG. 1 has a total of 16 concrete blocks (square shape having a side of 20 cm and a thickness of 8 cm) 2 arranged four each in front, rear, left and right,
A total of eight reinforcing bars (deformed reinforcing bars having a diameter of 9 mm) 3 arranged four each in the front-rear direction and the left-right direction, and these 16 concrete blocks 2 in total,
A mesh shape integrally connected at predetermined intervals (joint spacing 5 cm) between the blocks 2 and 2 adjacent in the front, rear, left and right by a total of eight streaks 3 previously arranged in the formwork at the time of manufacturing the block 2. Concrete product 1.

In order to construct the parking lot shown in FIG. 2 using such concrete products 1, a total of 10 concrete products 1 are laid 5 by 5 in the front and rear direction and 2 by 2 in the left and right direction. Between the blocks 2 and 2 constituting each concrete product 1 and adjacent concrete products 1 and 1
Is filled with a soil 5 and a plant 6 is vegetated on the soil 5. In addition, the walking part 8 of the usual interlocking block pavement was provided outside the green road surface in consideration of walking such as high heels.

The green road surface of the parking lot constructed in this way is
On the surface, it looks the same as a conventional one in which many blocks are laid with joints expanded. However, as shown in FIG. 3, a reinforcing material 3 between the blocks 2 and 2 is buried in the soil 5. Even if a jumping stress or a lateral displacement stress is applied to some of the blocks 2 due to running of the vehicle or the like, the blocks 2 are fixed integrally with the front and rear and right and left by the reinforcing members 3. The adjacent block 2 and the strut 3 suppress the jumping and lateral displacement of the sheet.

Further, as shown in FIG. 4, when the reinforcing material 3 is extended outside the block 2 located at the outer edge of the concrete product 1, when the plurality of concrete products 1 are laid, they are extended. By fixing the end portions of the reinforcing members 3 to each other by welding or the like, further integration can be achieved. It is to be noted that the reinforcement 3 may be extended to all the outside of the block 2 located at the outer edge portion, or the reinforcement 3 may be extended only to the outside of the block 2 located at the four corners as illustrated. You may make it do.

When a spacer 7 which is thinner than the block 2 is used, as shown in FIG. 5, a high restraining force acts on a stress which narrows the joint space between the adjacent blocks 2 and 2, thereby keeping the joint space constant. That is, the jumping and lateral displacement of each block 2 can be suppressed more reliably. Therefore, in the case of a parking lot such as a supermarket where cars come and go, the movement of each block 2 can be completely prevented by inserting the spacers 7 between all the blocks 2. Further, in the case of a parking lot or the like of a private house with few traffics of a car, a spacer may be inserted only between the concrete products 1 one by one.

FIG. 6 shows another embodiment in which the spacer is inserted between the blocks. The side surface of the block 2 'is inclined so as to expand downward and outward, and the spacer 7' is formed.
The side of the taper so that it narrows down and inward,
The structure in which the spacer 7 'is locked between joints in a wedge shape is shown.
In this case, since the spacer 7 'and the blocks 2', 2 'form a wedge-shaped locking structure, the integrality is particularly enhanced, and the spacer 7' jumps up and down as compared with the case where a simple rectangular spacer 7 is used. The force for suppressing the displacement becomes stronger.

FIG. 7 shows an embodiment in which spacers are integrally provided below the side surfaces of the block. A total of four spacers 21 each having a square planar shape are provided at one end of each side surface of the block 2. As shown in FIG. 8, two blocks 2 constitute the concrete product 1.
The configuration is such that one spacer 21 is interposed. As in the case of the fitting type spacer 7, the spacer 21 also exerts a high restraining force against a stress that narrows the joint space between the adjacent blocks 2 and 2, thereby maintaining the joint space constant. 2 can be prevented from rising and laterally displaced, and furthermore, the flatness is maintained by preventing bending of the exposed bar 3 in the concrete product 1 before laying, so that handling (handling) is excellent.

FIG. 9 shows another embodiment in which spacers are inserted between blocks. A spacer 7A having a substantially cross-shaped planar shape is formed by four blocks 2 adjacent in the front, rear, left and right directions.
And a spacer 7B having a substantially T-shaped planar shape is fitted between two adjacent blocks 2 located at the outer edge. Since such spacers 7A and 7B have a small number of attachments and a high stability after construction, they are more efficient and preferable than attaching at least a rectangular spacer. Further, the side surfaces of the spacers 7A, 7B are formed in a wedge-shaped structure similar to the spacer 7 'of FIG. 6 (the side surfaces are formed in an inclined shape so as to become narrower downward and inward. The side surface of the block 2 is also desirably inclined so as to expand downward and outward similarly to the block 2 ′ in FIG. 6).

FIG. 10 shows another embodiment in which a spacer is integrally provided below the side surface of the block.
A total of four spacers 22 each having an L-shaped planar shape are integrally provided so as to straddle adjacent side surfaces of the concrete product 1 constituted by the blocks 2. At the center, a cross-shaped spacer portion composed of four L-shaped spacers 22 is formed, and two spacers are located at the outer edge portion and between two adjacent blocks.
As a result, a T-shaped spacer portion composed of two L-shaped spacers 22 is formed, and has a planar shape similar to that of FIG.

As described above, according to the greening road surface structure of the present invention, the joint 4 is filled with the soil 5 and the plant 6 is vegetated after laying the mesh-shaped concrete product 1 or inserting the spacer 7 as necessary. With an extremely simple construction,
Parking lots, park squares, emergency vehicle approach roads, etc. can be constructed. In addition, since the constructed greenery road surface structure has a large number of concrete blocks 2 connected by reinforcing members 3 arranged integrally in front, rear, left and right, for example, a jumping stress to some of the blocks 2 due to running of a vehicle, etc. Even if a lateral displacement stress acts, the adjacent block 2 and the reinforcing member 3 suppress the jumping and lateral displacement of the block 2. Further, the spacers 7, 7 ', 7A, 7B are inserted or the spacers 21, 7', 7A, 7B are inserted.
In the case of using the blocks 2 and 2 ′ provided integrally with each other, a high restraining force acts on a stress that narrows the joint interval, and the joint interval is maintained constant, for example, when the vehicle is suddenly stopped or stopped. Even if a large amount of jumping stress and lateral displacement stress acts on some of the blocks 2, 2 'due to the sudden start, the jumping and lateral displacement of the blocks 2, 2' can be controlled by the adjacent blocks 2, 2 'and the reinforcement. 3 plus spacers 7, 7 ', 7
A, 7B, 21 and 22 can suppress it.

Further, the production of the concrete product 1 does not require enormous equipment costs unlike the conventional method using a block machine, and does not require a block piercing step or a reinforcing member fixing step. Furthermore, there are no restrictions on the product dimensions. Therefore, a product having a large area (dimension) exceeding, for example, 1 m square can be manufactured inexpensively, easily, and in a short time. Furthermore, since each block 2 constituting the concrete product 1 is connected to the front, rear, left and right by the reinforcing member 3, it has a higher rigidity than when it is connected by a flexible material such as a chain. It is excellent in handling (handling) even when performing work such as laying.

Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, but may be modified in any way unless the structure described in the claims is changed. Can be implemented.

[0020]

As described above, the green road surface structure of the present invention can be used to construct a parking lot, a park open space, an emergency vehicle approach road, and the like with extremely simple construction. Since a large number of concrete blocks are connected by reinforcing bars arranged integrally in front, rear, left and right, even if some blocks are subjected to a jumping stress or a lateral displacement stress due to, for example, running of a vehicle, they are adjacent to the blocks. Blocks and streaks can prevent the blocks from jumping and laterally displacing, and plants such as turf can efficiently grow at joints between the blocks.

Further, when a spacer thinner than the block is inserted between the blocks, or a block integrally provided with a spacer thinner than the block below the side surface of the block is used, the stress which narrows the joint space is reduced. A high restraint force acts on the spacer to keep the joint spacing constant. For example, even if a large jumping stress or lateral displacement stress acts on some blocks due to a sudden stop or sudden start of the vehicle, this spacer and the adjacent The jumping and lateral displacement of the block can be suppressed by the block and the strut. In particular, in a mode in which the spacer is fitted between the blocks, the side surfaces of the block are inclined so as to expand downward and outward, and the side surfaces of the spacer are inclined so as to narrow downward and inward. With the structure of being locked, the suppressing force against the jumping up and the lateral displacement becomes stronger.
