Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravestone installation structure and a gravestone installation method.

[0002]

2. Description of the Related Art Conventionally, gravestones are arranged in various ways according to the condition of each gravestone installation surface of a graveyard. For example, for a good-quality tombstone installation surface made of sand,
Tombstones may be placed directly (hereinafter referred to as "conventional example 1"). This is because, in the case of a sandy ground, the entire installation surface has substantially uniform compressive strength, and the load of the tombstone is easily applied evenly to the entire surface, so that the tombstone can be installed on this surface in a stable state.

On the other hand, graveyards are often provided on hills, mountains, and the like in the suburbs, and thus the gravestone installation surface is not necessarily a sandy ground with good conditions. For example, it may be made of clay or sand mixed with gravel. In such a case, the ground is loose or the compressive strength of the installation surface is often uneven,
Tombstones may not be able to be stably placed on such an installation surface. For this reason, the tombstone installation surface should be dug up as appropriate to form a recess, the bottom surface of the recess should be sufficiently solidified, and then the recess should be filled with sand, and the installation surface with poor conditions should be changed to a sandy installation surface (Hereinafter referred to as “conventional example 2”). In addition, after the gravestone installation surface having such poor conditions is sufficiently hardened, an underlay layer such as mortar is formed, and a gravestone is disposed thereon (hereinafter, referred to as "Conventional Example 3"). ).

[0004]

However, there is still room for improvement in the conventional gravestone installation structure or gravestone installation method shown here. That is, in the case of Conventional Example 1 in which the tombstone installation surface is originally a sand ground, or in the case of Conventional Example 2 in which a sandstone tombstone installation surface is artificially provided, water (for example, rainwater)
Due to the effects of wind, etc., the sand on the installation surface or its surroundings may be gradually eroded, and the stability of the tombstone may gradually decrease.
Further, in the conventional examples 2 and 3, the labor for providing the artificial sand or the underlay layer is large, and the construction cost of the gravestone installation is easily increased. In particular, in the case of Conventional Example 3,
Since gravestones cannot be arranged until the mortar or the like is sufficiently thirsty and hardened, the construction efficiency of gravestone installation tends to be low.

Further, the underlay layer of the mortar or the like of the conventional example 3 is characterized in that the hardness is sufficient, but the compressive strength is not so large, and it is easy to deteriorate. For this reason, cracks may occur in the underlayer due to rainwater, etc., which has soaked into the underlayer, deterioration of the mortar over time, or external forces applied during an earthquake, etc., and the stability of the tombstone may be impaired. is there. Further, since the underlay layer is heavy, the ground (soft ground or the like) below the underlay layer is gradually depressed by its own weight, and the stability of the tombstone may be impaired. In addition, regardless of the condition of the tombstone installation surface (whether it is sandy ground with good conditions or clayey with bad conditions, etc.), in the event of a major earthquake, etc. It may cause the stability of the tombstone.

[0006] Under the above circumstances, it is desired to dispose the tombstone in a more stable state with less labor and cost. At the same time, there is an urgent need to more reliably prevent "gravestone toppling", which tends to occur during an earthquake (particularly during a large-scale earthquake such as the Great Kansai Earthquake).

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned point of view, and enables tombstones to be installed in a more stable state, is excellent in seismic resistance and seismic isolation, and requires less labor and cost for installation. It is an object of the present invention to provide a structure and a method of installing a gravestone for realizing this structure.

[0008]

According to a first aspect of the present invention, there is provided a gravestone installation structure comprising: an underlay sheet material disposed on each gravestone installation surface of a graveyard; and a tombstone disposed on the underlay sheet material. An installation structure, wherein the underlay sheet material has a substantially honeycomb structure in which bottomed holes are juxtaposed along a thickness direction. The underlay sheet material in the present invention has a substantially honeycomb structure, for example, before and after along its planar direction,
The bottomed holes are arranged on the left and right at predetermined intervals. And while the partition part existing between each bottomed hole becomes like a rib on the vertical side provided in the thickness direction of the underlying sheet material,
It is arranged evenly over this sheet material. In addition, the bottom wall portion of each bottomed hole acts like a lateral rib provided in the plane direction of the underlay sheet material, and reinforces the entire partition portion.

Therefore, the load of the tombstone is applied in a state where it is dispersed throughout the underlay sheet material (mainly, the partition wall), and the underlay sheet material receives the load in a stable state.
The load dispersedly applied to the entire underlay sheet material is applied substantially uniformly to the tombstone installation surface. That is, the load dispersedly applied to the entire underlay sheet material is not only in the ground having good conditions such as sandy ground, but also in the poor condition such as clay ground, soft ground such as sand mixed with gravel, and ground having uneven compressive strength. For the ground,
It is loaded almost uniformly. Therefore, according to this installation structure,
Regardless of the condition of the gravestone installation surface, the gravestone can be installed in a stable state.

Further, since the underlay sheet material has a structure in which the partition wall portion is reinforced by the bottom wall portion, the underlay sheet material is stable against an external force along a lateral direction (a direction orthogonal to the thickness direction). For this reason, this installation structure can sufficiently counteract seismic loads having a vertical component and a horizontal component. Therefore, the installation structure is excellent in seismic resistance and seismic isolation. In addition to this, the underlay sheet material has a substantially honeycomb structure, is light in weight, and it is difficult to sink the tombstone installation surface by its own weight. Also, since the underlay sheet material is not a communication hole but a bottomed hole, it is difficult for rainwater or the like falling on the gravestone to reach the lower surface side of the sheet material. For this reason, it is possible to avoid as much as possible the occurrence of problems such as depression, erosion, and cracks caused by rainwater or the like on the gravestone installation surface. Therefore, irrespective of the condition of the ground on the gravestone installation surface, it is possible to maintain "stable gravestone installation performance" and "excellent seismic performance and seismic isolation performance", which are features of this installation structure, for many years.

On the other hand, even if a crack is formed on the gravestone installation surface in the event of a great earthquake or the like, the stability of the gravestone is sufficiently ensured unless the crack makes the entire underlay sheet material unstable. . For example, even if a crack is generated that cuts directly beneath the underlay sheet material, the underlay sheet material supports the tombstone in a stable state while covering the crack. Also,
Not only is the underlay sheet material lightweight and easy to handle,
By using this sheet material,
There is no need to provide artificial sand or an underlay layer. Moreover, this sheet material is generally manufactured outside the construction site (graveyard), and it is sufficient to arrange the sheet material in the construction site as it is or cut in accordance with the size of the tombstone installation surface. Therefore, according to the present invention, it is possible to improve the construction efficiency of gravestone installation and reduce the construction cost.

The bottomed hole provided in the underlay sheet material is not limited to a particular planar shape, and may have a polygonal shape such as a substantially triangular shape, a substantially square shape, a substantially hexagonal shape, a substantially octagonal shape, or a substantially circular shape. Other shapes, such as a substantially elliptical shape, may be sufficient. When the planar shape is substantially circular or substantially elliptical, the underlying sheet material has a substantially honeycomb structure having a substantially lotus root shape. In addition, the underlay sheet material may be mixed with various types of bottomed holes having various planar shapes.

According to a second aspect of the present invention, in the tombstone installation structure of the first aspect, the upper surface of the underlay sheet material and the lower surface of the tombstone are adhesively fixed. In the present invention, since the upper surface of the underlay sheet material and the lower surface of the tombstone are bonded and fixed, the stability, seismic resistance and seismic isolation of the installation structure of the tombstone are further improved. In addition, the gap between the upper surface of the underlay sheet material and the lower surface of the tombstone is sufficiently sealed with an adhesive, so that rainwater or the like can be reliably prevented from entering between the two. When an elastic adhesive (for example, an epoxy-based adhesive) is used as the adhesive, the stability, seismic resistance, and seismic isolation of the installation structure of the tombstone are further improved.

According to a third aspect of the present invention, in the gravestone installation structure of the first or second aspect, the gravestone is a basic constituent stone.
One or more pedestals and a Buddhist stone placed on the pedestals are provided, and abutment surfaces of adjacent basic constituent stones are bonded and fixed. In the present invention, since the basic constituent stones are adhered, it is difficult for the tombstones to be separated for each basic constituent stone even during an earthquake or the like. It is desirable to use an elastic adhesive (for example, an epoxy-based adhesive) as the adhesive as in the second aspect of the present invention. The “base stone” of the present invention refers to a stone that is stacked and placed between a gravestone installation surface (underlay sheet material) and a Buddhist stone.
For example, a lower table, a middle table, and an upper table can be exemplified. However, the number of pedestals is not particularly limited. Also, additional stones (flower arrangement, water bowl, etc.) other than the basic constituent stones may be bonded to any of the basic constituent stones.

According to a fourth aspect of the present invention, there is provided a method for installing a tombstone, wherein an underlay sheet material having a substantially honeycomb structure is provided on each tombstone installation surface of the graveyard, with bottomed holes arranged along the thickness direction. The tombstone is arranged on the underlay sheet material while being adhered and fixed to the upper surface of the underlay sheet material. In the present invention, it is preferable to use an elastic adhesive as the adhesive. In the same manner as in the invention of claim 3, "the tombstone includes one or more base stones and a Buddhist stone arranged on the base stone as basic constituent stones." It is desirable to dispose the tombstone on the underlay sheet material while adhering and fixing the abutment surfaces of the constituent stones.

[0016]

Embodiments of the present invention will be described below. In this embodiment, an example of an installation structure of a tombstone will be described with reference to FIGS. This installation structure includes an underlay sheet material 10 and a tombstone 20, as shown in FIG. Of these, the underlay sheet material 10 is made of a thermoplastic resin (EVA resin,
It is an integrated product manufactured using a polystyrene resin or an ABS resin, and has a substantially frame-shaped sheet-like outer shape as shown in FIG. That is, the underlay sheet material 10 has a substantially square planar outer peripheral edge, and has a substantially square planar bone insertion hole 11 in the center.

As shown in FIG. 2, this underlay sheet material 10 has a first bottomed hole 13 which is open on the upper surface side and has a hole bottom on the lower surface side, and a first bottomed hole 13 which is open on the lower surface side and on the upper surface side. It has a substantially honeycomb structure in which second bottomed holes 14 having hole bottoms are arranged. Each of the bottomed holes 13 and 14 has a substantially truncated conical shape in which the hole diameter decreases toward the hole bottom. Furthermore,
The first bottomed holes 13 are linearly arranged at substantially equal intervals along the left and right sides (may be front and rear) of the underlying sheet material 10, and may be bent along the front and rear sides (may be left and right) of the underlying sheet material 10. Are arranged at substantially equal intervals. That is, the first bottomed holes 13 are arranged in a staggered manner. Further, the second bottomed hole 14 is similarly arranged.

However, the position of the opening of the second bottomed hole 14 is shifted from the position of the opening of the first bottomed hole 13. Specifically, immediately below (directly above) the center of an equilateral triangle drawn by virtually connecting the centers of the openings of the three first bottomed holes 13 (second bottomed holes 14) arranged adjacent to each other. , The center of the opening of the second bottomed hole 14 (the first bottomed hole 13) is located. Further, between the upper surface U and the lower surface D of the underlay sheet material 10,
A partition wall portion 15 arranged in a vertical rib shape is provided while forming the peripheral wall surfaces of the bottomed holes 13 and 14. In the upper surface U, through holes forming the openings of the first bottomed holes 13 are provided in a staggered manner, and in the lower surface D, the through holes forming the openings of the second bottomed holes 14 are formed in a staggered manner. It is provided in. Furthermore, the bottom wall portion of the second bottomed hole 14 is formed by using the portion surrounded by the three adjacent through holes of the upper surface portion U, and the portion surrounded by the three adjacent through holes of the upper surface portion U is Using the first bottomed hole 13
Is constituted.

On the other hand, as shown in FIGS. 1, 3 and 4, the tombstone 20 comprises a lower stand 21, a middle stand 22, an upper stand 23, and a Buddhist stone 2
4, a roller 25, a pair of flower arrangements 26, and a water bowl 27. A substantially cylindrical carote 28 is disposed on the lower surface side of the lower base 21. Of these, the lower stand 21 is shown in FIG.
As shown in Fig. 5, a through-hole K penetrating through the upper and lower surfaces of a substantially rectangular stone material is provided. Although FIG. 5 illustrates the through hole K having a substantially rectangular shape in a plane, other shapes such as a substantially circular plane and a substantially elliptical plane may be used. Further, instead of forming the lower base 21 with one material, it is also possible to combine four pillar-shaped stone materials into a frame shape. Further, as shown in FIG. 5, mortise holes H and h having a substantially circular plane are provided at five places surrounding the through hole K on the upper surface of the lower base 21.

Further, as shown in FIG.
There is provided a concave portion S which is open on the lower surface and the front surface and can be aligned with the through hole K. In addition, on the lower surface of the middle base 22, four mortise holes H provided on the upper surface of the lower base 21 on the side and rear of the through hole K, and four mortise holes of a substantially circular shape which can be aligned are provided. (Not shown). In addition, an opening (bone insertion window) on the front side of the center table 22.
Will be closed using rollers 25.

Further, as shown in FIGS. 1, 3 and 4,
At the front and rear two places on the upper surface of the middle base 22 (two front and rear places on the symmetry plane along the front and rear), a substantially circular tenon hole is provided. A mortise that can be aligned with the mortise is also provided on the lower surface of the upper base 23. Furthermore, corresponding mortise holes are provided at the center of the upper surface of the upper stand 23 and the lower surface of the Buddha stand 24, respectively. A substantially columnar projection 66 protrudes from the lower surface of the roller 25.

Next, an example of the construction of this tombstone installation structure will be described. First, as shown in FIG. 6A, a carote insertion hole 50 is provided on the tombstone installation surface A. In addition, this carote insertion hole 5
It is desirable that the depth of 0 is slightly deeper than the overall height of the carote 28. Next, the carote 28 is inserted into the carote insertion hole 50. Then, the underlay sheet material 10 is transported to the tombstone installation surface A, and cut according to the size of the installation surface A. The underlay sheet material 10 cut in advance to a desired size may be prepared.

When the gravestone setting surface A is sandy,
As shown in FIG. 6B, the underlay sheet material 10 is arranged on the installation surface A, and is moved in the plane direction while being pressed from above. As a result, the sheet material 10 is buried underground. At the same time, as shown in FIG. 7A, the sand on the installation surface A is sequentially filled into the second bottomed holes 14. In the present embodiment, the depth of the carote insertion hole 50 is
, The upper end portion of the carote 28 does not hinder the movement of the sheet material 10 in the plane direction.

On the other hand, when the tombstone installation surface A is other than a sandy ground, after slightly sanding the installation surface A, the sheet material 10 can be moved in a plane direction while pushing the sheet material 10 from above.
The bottomed hole 14 is filled with sand. In the case where the ground on the installation surface A is hard (for example, in the case of clay), the plane shape is slightly larger than the sheet material 10 at this location, and a concave portion having a thickness of about the thickness of the sheet material 10 (conventional example 2). This is a recess which is much smaller and is easier to form than the recess of FIG. 1), sand may be slightly sprinkled in the recess, and the sheet material 10 may be moved in the horizontal direction. Further, the second bottomed hole 14 may be filled with a granular material other than sand, or the filling with sand or the like may be omitted. Furthermore,
Before the sheet material 10 is arranged on the tombstone installation surface A, the second bottomed hole 14 may be filled with sand or the like.
In this case, after filling the second bottomed hole 14 with sand or the like and closing the opening of the hole 14 with a resin sheet or the like, the work of disposing the sheet material 10 becomes easy. Further, the order of insertion of the carote 28 and arrangement of the underlay sheet material 10 may be reversed.

Next, after confirming that the upper surface of the underlying sheet material 10 is substantially horizontal and that the bone insertion hole 11 is aligned with the carote 28, the sheet material 10
Place sand on the top side of the and flatten this sand. Thus, the first bottomed hole 13 is also filled with sand. The first bottomed hole 13 may be filled with a granular material other than sand, or the filling with sand or the like may be omitted. Subsequently, FIG.
As shown in (b), after applying an elastic adhesive (for example, an epoxy-based adhesive) B to the upper surface of the underlay sheet material 10 (the portion excluding the through hole of the upper surface portion U), the lower table 21 is placed thereon. Mount. At this time, the through hole K is aligned with the bone insertion hole 11 and the carote 28. Thereby, the lower stand 21
Is firmly fixed on the underlay sheet material 10.

Further, a middle table 22 is mounted on the lower table 21. At this time, the two stands 21 and 22 are elastic adhesives (for example,
(Epoxy adhesive). In addition, each of the four mortise holes provided on the abutting surfaces of the two bases 21 and 22 has a cylindrical tenon 6 with an elastic adhesive applied to its peripheral surface.
2 are fitted, and both stands 21 and 22 are tenoned. In this way, the two bases 21 and 22 are firmly joined for adhesion between the abutting surfaces and tenon joint with adhesion. In joining the two tables 21 and 22, the recess S of the middle table 22 is aligned with the through hole K, the bone insertion hole 11, and the carote 28.

Next, the upper table 23 is mounted on the middle table 22, and the Buddhist stone 24 is mounted on the upper table 23. At this time,
The joining of the middle stand 22 and the upper stand 23 and the joining of the upper stand 23 and the Buddhist stone 24 are also strong due to the adhesion between the abutment surfaces and the tenon joints by the tenons 63 and 65 having an adhesive applied to the peripheral surface. Become. Further, the water bowl 27 is bonded and fixed to the front side of the upper surface of the middle base 22 using an elastic adhesive. Furthermore, a pair of flower arrangement 2
6 is adhesively fixed to the left and right front of the upper surface of the lower base 21 using an elastic adhesive.

Subsequently, the rollers 25 are arranged at the center of the front surface of the lower base 21 to complete the installation structure. This arrangement is performed by inserting the roller 25 protrusion 66 into the mortise h on the front side of the lower base 21. Therefore, the rollers 25 are detachable from the lower base 21. And when you remove rollers 25,
The opening (bone insertion window) on the front surface of the middle base 22 is opened, and the outside of the tombstone 20 and the carote 28 are in a continuous state. Therefore, when "bone" is inserted through the bone insertion window, the bone reaches the carote 28. In the present embodiment, the tombstone 20 is assembled by on-site construction.
May be transported to the tombstone installation surface A and installed on the underlay sheet material 10.

The installation structure described above has a substantially honeycomb structure, and the tombstone 20 is mounted on the underlay sheet material 10 in which the bottomed holes 13 and 14 are juxtaposed in front and rear, right and left. In the underlay sheet material 10, the ribs 15 in the form of vertical ribs are uniformly arranged on the whole. Moreover, each bottomed hole 1
The bottom wall portions 3 and 14 (part of the upper surface portion U and the lower surface portion D)
It acts like a lateral rib and reinforces the entire partition wall 15. For this reason, the load of the tombstone 20 is
The underlay sheet material 10 receives the load in a state where the load is distributed in the entirety (mainly, the partition wall portion 15) in a stable state. The load dispersedly applied to the entire underlay sheet material 10 is applied substantially uniformly to the tombstone installation surface A. That is, regardless of the state of the ground on the tombstone installation surface A, the load dispersedly applied to the entire underlay sheet material 10 is applied substantially uniformly to almost the entire surface A. In addition, in this installation structure, the bottomed holes 13 and 14 are filled with sand to further enhance the strength and shape stability of the underlying sheet material 10. In addition, the load in the tombstone 20 is also distributed to the sand in the bottomed holes 13 and 14 evenly provided in the entire underlying sheet material 10 in a state where the load is dispersed. Therefore, according to the present installation structure, the tombstone 20 can be installed in a stable state even on the ground with bad conditions.

Further, since the underlay sheet material 10 has a structure in which the partition wall 15 is reinforced by the bottom wall, it is stable against external forces along the lateral direction. For this reason, this installation structure can sufficiently counteract seismic loads having a vertical component and a horizontal component. Moreover, the underlay sheet material 10 and
The lower base 21 is joined with an elastic adhesive B having a strong joining force and an appropriate elasticity, and the respective basic constituent stones 21 of the tombstone 20 are attached.
24 are firmly joined by a similar elastic adhesive and tenon. Further, unlike the conventional product, the lower base 21 is made of one material. For this reason, even if it receives an external force, the underlay sheet material 10 and the tombstone 20 are prevented from being separated, and the tombstone 20 is prevented from being separated for each of the basic constituent stones 21 to 24. Therefore,
This installation structure is excellent in earthquake resistance and seismic isolation. In addition, in this installation structure, since the underlay sheet material 10 and the gravestone 20 are firmly integrated in this way, during an earthquake disaster, they follow the gravestone installation surface A and move horizontally to reduce the seismic load. It can be attenuated as appropriate.

Further, the underlay sheet material 10 has a substantially honeycomb structure, is lightweight, and it is difficult for the tombstone installation surface A to be depressed by its own weight. Furthermore, since the bottomed sheet material 10 is provided with the bottomed holes 13 and 14, rainwater or the like that falls on the tombstone 20 hardly reaches the lower surface side of the sheet material 10. For this reason, it is possible to avoid problems such as depression, erosion, and cracks on the tombstone installation surface A as much as possible. Therefore, irrespective of the state of the ground on the gravestone installation surface A, "stable gravestone installation performance" and "excellent seismic performance and seismic isolation performance" can be maintained for many years. Furthermore, even in the event of a major earthquake or the like, even if a crack is formed on the tombstone installation surface A, the stability of the tombstone 20 is sufficiently ensured unless the crack makes the entire underlay sheet material 10 unstable. From this point, this installation structure is also excellent in earthquake resistance and seismic isolation.

Further, the underlay sheet material 10 is lightweight and easy to handle, and by using this sheet material 10, it is not necessary to provide an artificial sand ground or an underlay layer on the ground having poor conditions. In addition, the sheet material is generally manufactured outside the construction site (graveyard), and it is sufficient to arrange the sheet material as it is or cut in accordance with the size of the tombstone installation surface A at the construction site. In addition, since the underlay sheet material 10 is made of resin, it is easy to cut it. Therefore, improvement of construction efficiency of tombstone installation,
The construction cost can be reduced. In addition, if each of the basic constituent stones 21 to 24 and the attached stones 25 and 26 are firmly integrated by bonding and tenon bonding as in the present embodiment, the entire tombstone 20 is lifted by a crane or the like and transported. You can also. For this reason, the gravestone 2 outside the construction site
It is easy to assemble and transport it to the desired tombstone installation surface A and arrange it on the underlay sheet material 10. In this case, the improvement of the construction efficiency of the tombstone installation and the reduction of the construction cost are further facilitated.

Further, for example, in a cold region,
When the water accumulates on the layers 3 and 14, the water turns into ice and freezes and expands, reaching between the underlay sheet material 10 and the lower base 21,
This ice may lift the lower stand 21 and impair the stability of the tombstone 20. However, in this installation structure,
Since the adhesive B between 0 and 21 also functions as a sealant, the possibility that rainwater or the like infiltrates between the two 10 and 21 is low. Moreover, even if water infiltrates between the two 10 and 21, the sand filled in the bottomed holes 13 and 14, particularly the sand filled in the first bottomed hole 13, penetrates the water into the bottomed holes 13 and 14. To block. Therefore, it is possible to reliably avoid the problem caused by the freezing and expansion of the water.

In the conventional tombstones, each of the basic constituent stones 21 to 21
24 are often made of mortar or the like.
For this reason, cracks and the like occur in the mortar and the like, and each basic constituent stone
Rainwater or the like may enter between 1 and 24, turning into ice, causing freezing and expansion, and impairing the stability of the tombstone 20. In some cases, a concave portion is provided on the upper surface of the upper base 23, and the lower end of the Buddhist stone 24 is inserted or fitted into the concave portion. In this case, rainwater may accumulate in the concave portion along the Buddha stone 24 or through a crack or the like of the Buddhist stone 24. This rainwater may also freeze and expand, impairing the stability of the Buddhist stone 24. On the other hand, in the present embodiment, since the gap between each of the basic constituent stones 21 to 24 is sufficiently sealed by the adhesive layer, the problem due to the freezing and expansion does not easily occur.

The scope of each invention described in each of the claims is as follows:
The present invention is not limited to the embodiments described above, and various modified examples can be exemplified within the scope of each invention described in each claim. That is, as a modification of the underlay sheet material 10, the one shown in FIG. 8 can be exemplified. First, in the underlay sheet material 10 shown in FIG. 8A, the outer peripheral edge G of the bottom wall portion 19a is spread in a substantially flange shape. For this reason, the bending rigidity and the like of the underlying sheet material 10 are further enhanced. Further, the adhesive B wraps around the back side of the outer peripheral edge G, and the adhesive strength between the underlay sheet material 10 and the lower base 21 further increases. The underlay sheet material 10 is shown in FIG.
As shown in FIG. 8B, only a bottomed hole 13b opening on the upper surface side may be provided, or only a bottomed hole 14c opening on the lower surface side may be provided as shown in FIG. 8C. . Further, as shown in FIG. 8D, a bottomed hole 13d opening on the upper surface side
And a bottomed hole 14d opening on the lower surface side, and a bottom wall portion 19d
May be shared.

In this embodiment, each of the bottomed holes 13,
Although the plane shape of 14 is substantially circular, it may be various shapes such as a substantially elliptical shape, a polygonal shape (a substantially triangular shape, a substantially hexagonal shape, etc.). Furthermore, although the bottomed holes 13 and 14 are regularly arranged, they can be arranged randomly. In addition, the installation structure of the tombstones according to claims 1 to 3 and the installation method of the tombstones according to claim 4 include various stone structures (gravestones, stone monuments,
Gates, walls, etc.).
