Description

Description: TECHNICAL FIELD The present invention relates to a wooden brick for laying on a sidewalk or a parking lot to form a pavement road surface.

[Prior Art] Conventional wooden bricks have been formed in a substantially planar square shape by arranging a wooden tip vertically.

In the old days, these wooden bricks were formed by forming a foundation made of flat concrete or the like and arranging them under the ground with mortar or the like.

However, such a wooden brick pavement requires skill to construct a flat pavement road surface, is extremely inefficient, and furthermore, the wooden brick repeatedly expands and contracts due to changes in the moisture state due to rainwater or the like, so that it can be used immediately. Peeling from the underlayer occurred, resulting in an extremely impractical result.

Therefore, the present inventor has proposed a technique of obtaining a wooden brick pavement by developing a wooden brick laying frame, and holding the wooden bricks by using the frames to connect them on a flat gravel foundation or the like. And it has already achieved considerable results.

By the way, these wooden brick laying frames generally constitute holding sections in the frame body, and after holding the wooden bricks in those holding sections, laying them in a predetermined area to complete the pavement of the wooden bricks. (For example, JP-A-64-33301).

[Problems to be Solved by the Invention] As described above, wood bricks repeatedly expand and contract with a change in the moisture state. Therefore, when laying wooden bricks in the target area without using the laying frame as described above, when the wooden bricks expand due to rainwater, a plurality of wooden bricks come to press against each other on the side, and finally the arch-like It often happens to emerge. The above laying frame is
Although it is configured to absorb the expansion and contraction of the wooden bricks to a considerable extent, the expansion and contraction of the wooden bricks may still exceed expectations, in which case, similarly, the wooden bricks expand in the shape of an arch and In some cases.

An object of the present invention is to obtain a wooden brick that does not cause such a phenomenon. At the same time, it is another object of the present invention that the paved road surface made of wooden bricks is hard to slip for pedestrians and the like, and that various guidelines and the like can be displayed as necessary.

[Means for Solving the Problems] The gist of the present invention is to provide, on the upper surface of the brick body, a surrounding portion one step lower than the inside along the periphery thereof, and inside the surrounding portion on the upper surface, elasticity is provided. A tree having at least one spherical protrusion having fluorescence and having an inclined portion formed on the peripheral side so that the upper surface is inclined upward at least from the middle of the vertical direction. It is a brick.

The brick body can have various basic shapes. For example, it can be configured to be square, rectangular or circular when viewed from a plane.

It is appropriate that the surrounding portion is configured to be about 2 to 3 mm lower than the inner surface thereof. The width of the surrounding portion is suitably about 10 mm.

For example, in the case of a plane square or circular brick main body, the protrusion is suitably formed at the center thereof. Further, in the above-mentioned flat rectangular brick body, it is appropriate to form a plurality of bricks at appropriate intervals on an assumed center line along the center in the width direction.

The protruding portion can be variously configured.For example, a hole having an appropriate depth is formed in a corresponding position of the brick body, and an adhesive is put therein, and the upper end is formed in a spherical shape. Is filled with an elastic member having a protruding surface and is fixed by bonding. Alternatively, an elastic member is inserted into the hole, and a screw is screwed into the brick body from a space for a screw head above the elastic member which has been previously drilled and fixed. The upper part of the elastic member is coated with a fluorescent paint or the like, and the inside is further impregnated.

The inclined portion is configured such that the upper surface side becomes smaller from the lower part on the peripheral side of the brick body or from the middle to the upper surface. In the case where the inclined portion is formed from the vicinity of the middle in the vertical direction with a brick body having a thickness of about 40 to 50 mm, the inclined portion may be configured such that the upper surface side retreats by about 2 to 3 mm from the lower end side. The magnitude of the inclination angle of the inclined portion and the position on the peripheral side are determined in consideration of the degree of expansion and contraction due to a change in the moisture state due to wood and the size and shape of the brick body. The purpose of this slope is to cope with expansion and contraction due to a change in the moisture state of the wooden brick.

According to the observation by the inventor of the expansion and contraction of the wooden brick, it is particularly large at the upper part and hardly occurs at the lower part, so that it is possible to cope with the expansion at the upper part. That is the purpose.

[Operation] Since the present invention is configured as described above, for example, it can be laid in a target area using the following wooden brick laying frame to configure a wooden brick paved road surface. These wooden bricks do not cause arch-like floating from the laid position and other problems despite expansion and contraction due to fluctuations in the moisture state due to rainwater or the like.

First, an example of a laying frame for holding the wooden brick will be described.

The laying frame includes a base frame having a plurality of holding sections for separately arranging a plurality of wooden bricks, and a tree arranged in each of the holding sections at positions vertically corresponding to the respective holding sections of the base frame. Auxiliary frames with auxiliary sections that hold down the upper edge of the bricks, and a base frame on which wooden bricks are arranged in each holding section, the auxiliary frames are each made to correspond to the holding section. A mounting means provided on the base frame and the auxiliary frame so as to be connected to each other,
And connection means for connecting adjacent laying frames provided on the outer frame of the base frame.

Accordingly, the wooden bricks can be held on the wooden bricks, and can be continuously arranged on the prefabricated foundation. By using the laying frame in this way, it is possible to complete the pavement with the wooden brick very easily.

It is preferable that a permeable base such as a gravel base be flatly formed in the required laying area.

On the other hand, prepare the number of laying frames according to the area of the required laying area,
The wood brick is placed in each holding section of the base frame. After that, the auxiliary frame is placed on the base frame. Thus, the upper edge of the wooden brick arranged in the holding section is pressed by the auxiliary section. Subsequently, the base frame and the auxiliary frame are connected to each other by a connecting means.

The wooden bricks arranged in the holding section of the base frame in this manner are, by the holding section and the auxiliary section of the auxiliary frame,
It will be held in a state of being clamped up and down. Thus, the wooden brick is securely fixed to the holding section.

In this way, the required number of laying frames holds the wooden bricks in a sandwiched state.

Next, the laying frame holding the wooden bricks is successively arranged on a foundation formed in the required laying area.

Adjacent laying frames are connected to each other by connecting one male connecting means and the other female connecting means.

Thus, a flat pavement made of wood bricks can be formed very easily in this way.

On the wooden brick pavement road surface configured in this way, the wooden bricks held in the laying frame will repeatedly expand and contract with the change in the moisture state, but when contracted, there is no particular problem, and when expanded, Since each wooden brick has an inclined portion on the peripheral side, the upper portion on the peripheral side can be in an upright state or can be expanded only to a degree slightly beyond this.
Therefore, the wooden bricks do not come off from the laying frame, or even if they do not come off, a plurality of them do not cause a situation in which they float in an arch shape. The expansion and contraction of the wooden brick is absorbed by the inclined portion formed on the peripheral side. That is, the expansion and contraction of the wooden brick is as large as the upper part and hardly occurs near the lower end.

In addition, on a pavement road surface made of such a wooden brick, slip of a pedestrian or the like is prevented by the configuration of the surrounding portion. Also, the protrusions are useful for preventing slip. Furthermore, by coloring the protrusions as necessary,
It can also be used as a mark for drawing a parking space.

Accordingly, as described below, the wooden brick is held in each of the holding sections 7, 7,..., And is arranged continuously in the required laying area, whereby a flat pavement can be easily completed. Things.

For this purpose, first, a flat ground is formed in the required laying area. In this example, the substrate is a gravel substrate 18 having good water permeability.

The gravel foundation 18 is formed by slightly digging down the required laying area, introducing gravel, compacting, and applying sand to adjust unevenness.

On the other hand, a number of laying frames corresponding to the area of the laying area required are prepared, and wooden bricks are inserted and held in the holding sections 7, 7,....

The wooden bricks thus arranged in the holding sections 7, 7,... Of the base frame 5 are held by the laying frame as shown in FIGS.

Next, as shown in FIG. 5, the laying frames holding the wooden bricks are successively arranged on the gravel foundation 18 formed in the required laying area.

Adjacent laying frames are connected by connecting one connecting male part 11, 11 and the other connecting female part 12, 12.

In this way, the laying frames are laid all over the gravel base 18 in the required laying area while connecting the laying frames to each other. Then, by simply laying the laying frames holding the wooden bricks on the base while interconnecting them, a flat pavement made of the wooden bricks can be formed extremely easily.

FIG. 10 shows an example of another wooden brick to which the present invention is applied.

This consists of a brick body 21 whose basic shape is rectangular when viewed from above, as shown in FIG. The length of the long side of the rectangle viewed from the plane of the brick body 21 is about 300 mm,
The length of the short side is about 100mm and the thickness is 40mm. Needless to say, the brick body 21 is made of a wooden material.

On the upper surface of the brick main body 21, a surrounding portion 22 is formed along the edge of each side and about 2 mm lower than the inner side. This width is about 10 mm.

Elastic spherical projections 23, 23, 23 are formed on a line supposed along the length direction at the center in the width direction of the upper surface of the wooden brick body 21. This configuration is the same as in the above-described embodiment.

Further, on the peripheral side of the brick main body 21, there is formed an inclined portion 24 which is inclined upward from a position slightly lower than the center in the vertical direction so that the upper surface side becomes smaller. This ramp
24 is retracted about 2 mm from the outermost peripheral surface at the upper end.

This wooden brick is configured as described above, and if a laying frame is used, it is the same as the above-described embodiment, except that the size of the holding section is set to a corresponding dimension. Therefore, the description of the usage and operation is omitted.

[Effects of the Invention] According to the present invention, when laid in the required laying area without being held or held by the laying frame as described above,
In the constructed wooden brick paved road, the wooden bricks will repeatedly expand and contract with the change of the moisture state, but even if it expands, configure a slope on the peripheral side of each wooden brick As a result, the upper peripheral portion is in an upright state or expands only slightly beyond this. As a result, in the case of using the laying frame, there is no possibility that the laying frame rises in the shape of an arch with the plurality of laying frames even if the laying frame does not come off. The same applies to the case where the individual units are laid separately.

That is, the expansion and contraction of the wooden brick is absorbed by the inclined portion formed on the peripheral side. In addition, the reason why the inclined portion is effectively operated is that the expansion and contraction of the wooden brick is as large as the upper portion and hardly occurs near the lower end.

In addition, on a pavement road surface made of such a wooden brick, by forming the surrounding portion, appropriate unevenness is generated on the road surface, and slip of a pedestrian or the like is prevented. Also, the protrusions are useful for preventing slip. Further, the protrusions may be colored as necessary to be used as marks or the like depicting parking spaces.
