Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for inserting a concrete plate into a space between concrete plates, brick-shaped plates, or wooden bricks laid on roads, various plazas, etc. The present invention relates to joint constituent materials that constitute joints.

[Prior Art] Flat plates such as concrete road plates, brick-shaped plates, wooden bricks, etc., which are laid as pavement for various road surfaces, often have their joints filled with sand or asphalt.

[Problems to be solved by the invention] As in the former case, when sand is charged into the joints of flat plates, etc., the sand is not fixed in the joints.
When people walk on the road surface or vehicles run on it, sand often flies out from the joints and is scattered on the road surface due to impact, wind pressure, or other various circumstances, spoiling the aesthetic appearance.

Furthermore, when the joints are filled with asphalt as in the latter case, water permeability is lost and water tends to accumulate on the road surface during rainy weather. Furthermore, there is the problem that the melt is released in the summer, staining the road surface and the footwear of pedestrians.

[Means for Solving the Problems] The gist of the configuration of the present invention is to provide a container body composed of a pair of end walls, a pair of side walls, an upper end wall, and a lower end wall, the width and height of which are This is a joint forming material in which the material corresponds to that of the joint to be inserted, its planar shape corresponds to that of the joint, and a large number of holes are formed in each of the walls.

A large number of holes are formed in the 6 walls by forming them in a net shape or a lattice shape, as described above.

The dimensions of these holes are appropriately determined depending on the type of filler described later to be filled into the joint material. For example, when the filler is sand, the pores are formed to be slightly larger than the maximum grain size of sand, and when the filler is gravel, the pores are determined to be slightly larger than the maximum grain size. When growing ground plants,
The holes at the upper end are designed to be sufficient to allow the stems and leaves to advance upward, and to provide sufficient protection from treading pressure, etc. The holes in the walls other than the top end should be determined according to the material that makes up the soil.

It is preferable that connecting means corresponding to each other be formed on both end walls, but the structure thereof is free. For example, one end has a connecting recess and the other end has a connecting protrusion.

In addition, flat plates or wooden bricks are laid on a part of the upper edge and a part of the lower edge of the side wall.

Preferably, retaining pieces project from the upper end wall and from the lower end wall in a direction in which they extend.

When these holding pieces are formed, it is preferable that an engagement recess is formed in a flat plate or the like that forms a joint using this joint forming material in correspondence with the holding piece.

[Function] Since the present invention is configured as described above, it can be used to form joints when paving roads etc. using flat plates such as road concrete plates and brick-shaped plates, or wooden bricks. can.

The joint construction work is carried out as follows.

First, the joint material is selected in accordance with the size and shape of the joint formed by the flat plates to be laid. When the planar shape of flat plates or the like is rectangular or square, and the outline is straight, use a square joint material. Select one with a height and width that corresponds to the height and width of the joint to be formed. When the planar shape of flat plates or the like is special, a joint with a corresponding special planar shape is formed, and in that case, a joint constituent material with a corresponding planar shape is prepared.

Then, the joint material is filled with sand or gravel, or filled with soil, and planted with local plants such as lawns, depending on the paving pattern formed in advance or preference. In either case, this is done through a number of holes in the wall, although it is not inconvenient to fill the joint material with sand or gravel after the joint is formed.

The above-mentioned joint forming materials are then inserted into the spaces between the flat plates and the like to be laid in the following manner.

For example, flat plates or the like are laid one after another on a substrate at predetermined joint intervals, and then joint forming materials are inserted into the intervals. Alternatively, flat plates, etc. and joint materials are placed alternately, that is, one flat sheet is laid, the joint material is installed on the side of it, another flat sheet is laid next to it, and then a joint is placed on the side of the flat sheet. It is installed like installing component materials.

As mentioned above, when the holding pieces are provided protrudingly from part of the upper and lower edges of the side walls of the joint material, the latter procedure is followed. Place the joint material on the side of the laid flat plates while holding the upper and lower surfaces of the flat plates with the holding pieces, and further hold the upper and lower surfaces on the side of the joint material with the holding pieces. Arrange the flat plates as shown. This is repeated.

Note that the connection in the end direction of the joint constituent material is performed by engaging the connection recess and the connection protrusion.

Furthermore, when using a joint material for the joints of flat plates, it is preferable that the paving base is water permeable.

For example, a water-permeable pavement base can be created by laying crushed stone or the like in a predetermined desired area, compacting it, and then adding sand to adjust the unevenness.

Therefore, the road surface on which flat slabs, etc. are laid, has joints made of a joint material filled with sand or gravel, or a joint material covered with grass or other ground plants. No sand or gravel will fly out and scatter,
In addition, since the grass and other ground plants in the joints are sufficiently protected from the pressure of pedestrians and vehicles, water permeability is ensured and the aesthetic appearance is maintained.

[Example] The present invention will be described in detail below based on the drawings.

First, a first embodiment will be described based on FIGS. 1 to 3.

As shown in FIG. 1, a pair of ends 11.1. Pair of side walls 2.2. The upper end wall 3 and the lower end wall 4 constitute a rectangular parallelepiped cage-shaped joint component.

6 Walls 1, 1.2.2.3.4 were constructed in a grid pattern, with holes occurring between the grids.

This joint material is filled with small gravel 5.5..., and the wall l
, 1.2.2.3.4 grid dimensions were determined.

Note that one end wall 1 of the joint component is provided with a connecting protrusion 6 that expands toward the tip, and the other end wall 1 is provided with a connecting recess 7. Naturally, the connecting protrusion 6 and the connecting recess 7 are constructed in corresponding shapes, and the connecting protrusion 6 of the end wall l of one adjacent joint member is slid into the connecting recess 7 of the end wall l of the other joint member. and ensure consistency.

Since this embodiment is configured in this way, it can be used to form joints when roads are paved with flat plates such as road concrete plates or brick-shaped plates, or wooden bricks. .

Here, when constructing a paved road using concrete flat plates 8, an example will be described in which a joint forming material is inserted between each concrete flat plate 8 to form a joint.

First, the base 9 is made water permeable. After excavating a designated area, crushed stone is laid down, compacted, and then sand is added to adjust the unevenness.

Thereafter, a concrete flat plate 8 is laid on the water-permeable base 9 thus created. The joint constituent material is placed in contact with the 70-side edge every time one concrete flat plate 8 is laid, and is then laid together with the concrete flat plate 8 in the required area.

At this time, the joint members that are adjacent to each other on the end wall 1 are connected by engaging and sliding the connecting protrusion 6 into the connecting recess 7, as shown in FIG.

Incidentally, it is assumed that the joint forming material to be charged into the joints of the concrete flat plates 8 as described above is filled with small gravel 5.5 in advance. Small gravel 5.5... is 6 walls 1, l, 2
．． It can be filled through a large number of holes formed by the lattice of 2.3.4.

However, since the paved road surface made of concrete flat plates 8 is constructed of joint material filled with small gravel, water permeability is ensured and rainwater does not accumulate on the road surface. However, since the base 9 is also made water permeable, rainwater can reliably permeate underground.

Furthermore, as mentioned above, the small gravel 5.5... in the joint is filled in the joint material, so it will not fly out and scatter.6 walls 1.1, 2.2 of the joint material. The lattice dimensions of 3.4 were made to be sufficient for small gravel 5.5... to enter and exit, but the difference in size caused only small gravel 5.5... to enter and exit the joints.
Since it is not as large as when it is charged, it does not fly out easily.

Next, a second embodiment will be briefly described based on FIGS. 4 and 5.

The joint constituent material of this embodiment is different from that of the first embodiment described above, and the holding pieces 10, lO...
It is a projecting structure. Other configurations are the same.

As shown in FIG. 4, the holding pieces 10, 10, .

As shown in FIG. 5, the concrete flat plate 8 has engaging recesses 11, 11, .
The holding pieces 10, 10, and so on are formed at positions corresponding to the holding pieces 10, 10, and so on.

The above-mentioned joint forming material is then charged into the gaps between the concrete plates 8 and 8 to be laid for paving roads and the like.

This is done by repeating the laying of the concrete flat plate 8 and the installation of the joint forming material alternately. At this time, the engaging recesses 11, 11... of the concrete flat plate 8 are filled with , engage the holding pieces 1O110 of the joint constituent material.

When this joint material is used, in addition to the effect of the first embodiment, it has the effect of suppressing the vertical movement of the laid concrete flat plates 8.8.

6 to 8 show third to fifth embodiments. Used for paving with flat plates that create joints with shapes that correspond to the planar shape of each joint component. The usage is the same as in the first and second embodiments above.

However, the joint materials of the third to fifth embodiments can be filled with sand or suitable soil to grow grass.

After this, when it is charged into the joints of the relevant flat plates, sand joints or grass joints can be formed.

[Effects of the Invention] According to the present invention, even when sand or small gravel is charged into the joints in paving with flat plates or the like, the sand or gravel does not scatter and the aesthetic appearance can be maintained. In some cases, native plants such as lawns can be grown in the joints in a protected state.

Furthermore, as described above, the joints can be filled with sand or gravel or planted with local plants, so that water permeability can be ensured.
