[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden brick laying frame in which a creeping plant such as a lawn can be planted between held wooden bricks.

[0002]

2. Description of the Related Art A wooden brick laying frame is related to the proposal of the present inventor, and generally, a plurality of holding sections are formed in a frame body, and a section wall which divides the holding sections has oblique downward elasticity. A brim piece is constructed, and this wooden brick laying frame is laid in a predetermined area after holding the wooden bricks in its holding section to complete the paving of the wooden bricks (JP-A-64). -33301).

In the above-mentioned conventional wooden brick laying frame, it is assumed that the wooden brick pavement can be constructed flatly without any difference in height between the wooden bricks, more easily and speedily. In the wooden brick pavement to be constructed, the laid wooden brick is intended for the purpose of not causing inconvenience such as peeling from the base even by expansion and contraction due to the change of the moisture state. is there.

On the other hand, the inventor of the present invention has proposed a crawling plant protection stepping plate as a member for protecting only crawling plants.
One of them is generally composed of a lattice-shaped member with a cylindrical body arranged at each intersection, and this protective footboard is placed on a crawling plant such as lawn to protect them from the trampling of humans. This is done (Act No. 52-47289, No. 57).
-3386). In other types, the inside is divided into a large number of protective compartments in the shape of a box, and the protective treads are arranged in a predetermined area, and then, in each protective compartment of these members. The soil and the creeping plant are charged in the above, and the above creeping plant is configured to be protected from the pedaling pressure of a person or a vehicle at the upper end of the partition wall (Act No. 57-8443, etc.).

The present inventor has further proposed the following as a wooden brick laying frame in which the former is combined with the latter (Japanese Patent Application No. 1-181317). That is, `` a quadrangular frame when viewed from above, with a protective compartment for the crawling plant interposed between adjacent ones, to form a plurality of quadrilateral holding compartments vertically and horizontally as viewed from the plane that holds the wooden bricks. Then, on each partition wall that partitions between the holding section and the protective section, an elastic brim piece having elasticity inwardly and downwardly of the holding section is configured to project,
And, in the vicinity of both ends of each of the partition walls that partition between the holding partition and the protective partition, the partition wall itself can open outward to the holding partition around the lower edge as an axis center, and the slit from the upper end to the middle Forming a bottom plate with a water-permeable opening at the bottom of each holding compartment, and connecting the facing partition walls to each other on the bottom side in the protective partition between the slits of each partition wall. In addition, connecting male parts are provided on two adjacent sides of the frame body, and connecting female parts are connectable on the other two sides with the connecting male parts of the other frame bodies. Part, when connecting the connection male part and the connection female part of the adjacent frame,
It is a wooden brick laying frame configured so that a space having the same width as the width of the protection section is formed between the frames.

[0006]

The wooden brick laying frame of the conventional example shown last is basically the same as the wooden brick laying frame of the conventional example firstly combined with the configuration of the crawling plant protection step. In addition to making it easier to absorb the expansion and contraction of wooden bricks due to changes in the water state held, it is possible to grow crawling plants such as lawns between the wooden bricks, to create a moist sidewalk and parking. Is made easier. The present invention relates to the improvement of the last-mentioned conventional example, and an object thereof is to provide a wooden brick laying frame that can more completely protect a creeping plant vegetated between wooden bricks.

[0007]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a plurality of wooden bricks for holding a wooden brick with a quadrangular frame body as seen in a plane and a protection section of a crawling plant interposed between adjacent frame bodies. The holding partition is configured, and each partition wall partitioning between the holding partition and the protection partition is provided with an elastic brim piece that extends obliquely downward and inward of the holding partition, and the lower part of each holding partition is provided. A bottom plate having a water-permeable opening is formed, and in the protective compartment,
A connecting member that connects the partition walls that partition this is configured, and a treading protrusion whose upper end is slightly lower than the upper surface of the wooden bricks held in the holding compartment is erected in the protective compartment. On the other hand, on each side of the frame body, a connecting male part and a connecting female part which are symmetrically positioned, and when connecting the connecting male part and the connecting female part of the mutually adjacent frame bodies, It is a wooden brick laying frame that has a connecting male part and a connecting female part in which a gap having the same width as the width of the protection section is formed between the bodies.

The frame body includes partition walls for the holding compartments and protective compartments, elastic brim pieces, a bottom plate, a connecting member,
It is suitable to integrally mold the connecting male part and the connecting female part with the elastic plastic material. The planar shape of the frame is a quadrilateral, but a square or a rectangle is suitable for the convenience of installation. In addition, the planar shape of the holding section is a normal quadrilateral in relation to the shape of wooden bricks, but there is no reason to limit the shape in particular.
For example, a circle, an ellipse, or a pentagon or more polygon may be used. The protection section may be formed as a space having a relatively narrow width in the gap between the holding sections arranged in the vertical and horizontal directions. That is, the width of the protection section is set such that the crawling plant inserted therein can be protected from the pedaling pressure of a pedestrian, a vehicle, etc. by the wooden bricks around the plant and the pedaling projections standing upright in the protective section. When corresponding to the most common wooden bricks as described above, the holding section, each configured in a quadrilateral viewed from the plane, the plurality of holding sections in the frame, while leaving a gap between each other. The lattice-shaped gaps, which are arranged vertically and horizontally when viewed from the plane formed between the holding sections, can be used as the protection section for the creeping plants.

When the wooden brick is loaded into the holding section, the lower end of the elastic brim piece is locked in the holding section so that it is fixed in the holding section.
It is suitable to form a step that expands downward. However, it is not necessary to limit to this. A lawn is suitable as the crawling plant. Of course, it is also possible to adopt a suitable plant that crawls on another land. The connection male part and the connection female part are not limited to any particular ones as long as they satisfy the above conditions and can be connected to each other.

The protective compartment may be covered with a protective cover for complete protection of the creeping plants vegetated therein. The protective cover has a planar outer shape corresponding to the planar shape of the protective section, and the inner side is configured in a net shape. Suitably, the protective cover is configured to be fixed to the tread pressure projection.

[0011]

Since the present invention has the above-mentioned structure, as described below, it is possible to construct a wooden brick pavement in which a crawling plant is arranged around a wooden brick in a required laying area. A water-permeable substrate such as a gravel substrate is flatly formed in the required laying area. Although a base such as concrete or asphalt can be used, the above-mentioned water-permeable base is suitable.

Further, a number of frame bodies corresponding to the area of the laying required area are prepared, and wooden bricks are loaded and held in the respective holding sections.
When it is decided to use a wooden brick having a step formed in the middle of the outer circumference, it is only necessary to insert it. When you push in a wooden brick, the elastic brim piece configured on the partition wall,
Due to its elasticity, it retreats outward along with this, allowing smooth loading. When the lower end of the elastic brim piece is lowered until it comes into contact with the bottom plate, the lower end of the elastic brim piece crosses over the step on the outer circumference of the wooden brick and comes into engagement therewith. The wooden bricks are then firmly fixed in the holding compartment.

Naturally, there is no inconvenience even with a wooden brick which does not form the above-mentioned step on the outer periphery. It is loaded into the holding section in the same procedure as described above, and is almost fixed by the elastic brim piece. In this case, in order to secure the above fixation,
It is suitable to use other fixing means together. For example, a screw hole is bored in the bottom plate, and a screw is screwed from the back surface through the screw hole to the bottom side of the wooden brick inserted into the holding section to fix it. In this way, wooden bricks are loaded and held in the required number of holding sections of the frame.

Next, the frame body of the above-mentioned wooden bricks, which has been held, is continuously arranged on the groundwork formed in the laying required area. By connecting one connecting male part and the other connecting female part, the adjacent frame bodies are connected to each other with a gap space having the same spacing as the width of the protective section opened between them. .. After the frame body is laid over the entire required laying area while being connected as described above, the creeping plants are vegetated in the protective spaces in each frame body and in the gap space formed between each frame body. For example, soil is filled in the protective compartment and the above-mentioned gap space, some fertilizer is applied thereto, and then crawling plants, for example, lawn seeds are sown. Then water it. Alternatively, the same place is filled with soil, some fertilizer is applied, and then a crawling plant such as lawn is transplanted and watered.

However, a flat wooden brick pavement containing crawling plants around a wooden brick can be created very easily. On the wooden brick paved road surface configured in this way, the crawling plants arranged in the above-mentioned clearance space between the frame and the protective compartment of the frame do not directly receive the pedaling of the pedestrian or the vehicle, and the trees around it. It will be protected by the bricks and the tread pressure protrusions that are erected in the protection compartment. However, crawling plants can easily be included in the wooden brick pavement. By the way, the wooden bricks held in each holding section of the frame body is to repeat expansion and contraction with the change of the water state, but the expansion and contraction is the section of the elastic brim piece that is formed to overhang the partition wall. It is absorbed by the elastic movement in and out.

By the way, when this paved road surface is used as a parking lot or as a road surface on which a vehicle passes, or when this paved road surface is a road surface that is relatively frequent, it is relatively severe against the growth of crawling plants. When it is considered that the above conditions are satisfied, the protective cover is coated on the upper part of the gap space between the protective compartment and the frame body. The height of the upper surface is slightly lower than the height of the upper surface of the wooden brick. The protective cover is suitably fixed to the pedal depression.

By doing so, the creeping plants vegetated in the space between the protective compartment and the frame can be almost certainly protected.
