Description

[Detailed description of the invention] <Industrial field of application> The invention provides a sealed structure for the urn storage area, and
This invention relates to a tombstone with a new structure that integrates an underground foundation and a pedestal.

<Prior Art> The structure of a tombstone conventionally constructed was as follows.

In other words, the ground is excavated and removed to form a hole according to the capacity required for storing the urn, concrete is poured into the bottom of this hole, and before the concrete hardens, concrete blocks are placed around the bottom of the hole. etc. to build a wall to ground level. and,
After the concrete hardens, the gap between the hole and the wall surface formed by the concrete block is backfilled using the soil discharged. The space surrounded by the concrete wall is used as an urn storage room, and a pedestal with a structure that allows the urn to be taken out and stored is placed on top of the urn, and a pole stone is placed on top of this pedestal. The main thing was the structure of the tombstones placed on them.

<Problem that the invention aims to solve> Due to this structure, if the storage room for the urn is enlarged, the foundation for building the tombstone tends to become weak. It was difficult to simultaneously ensure the strength of the steel. In addition, the pedestal is installed after the concrete has hardened, so if the concrete is not a level foundation or the thickness of the pedestal with an uneven surface finish is not uniform, in order to make the pedestal level, it is necessary to remove dirt, stone chips, etc. I had no choice but to pack things in.

As a result of these, the tombstones (hereinafter referred to as
In this invention, this "tombstone" collectively refers to above-ground structures such as pedestals and pole stones other than underground structures such as foundations and storage rooms, and is used to distinguish it from "tombstone"). Condensation due to capillary absorption of soil moisture, rainwater seepage through gaps, and insect nesting were frequently observed in the storage room. Furthermore, since urns are usually made of materials with low water resistance such as porcelain or ceramics, the preservation condition of the contents is extremely poor due to rainwater that has entered the storage chamber and seeped into the urn. It was.

It has also been proposed to form a concrete wall around the outer periphery of a metal or plastic casket (Utility Model Publication No. 49-45897, 45898), but the opening is located outside the tombstone, and there is no way to ensure watertightness of the opening. Furthermore, there is a problem in that fine sand can enter and accumulate in the meshing area between the lid of the delivery port and the main body, causing grass to take root in this.

Since the entire weight of the gravestone is carried by the columbarium, if the load of the gravestone is concentrated on a part of the columbarium due to an earthquake or slight subsidence of the ground, cracks may occur, causing water to leak into the columbarium or causing damage. becomes a factor.

Furthermore, it is not sufficient as a foundation structure for the tombstone, and the tombstone may tilt.

<Means for Solving the Problems> Therefore, in order to solve the above-mentioned drawbacks, an opening 4 for taking out and storing urns, etc., made of a corrosion-resistant material such as metal or plastic, and having a raised edge around the urn, and its lid. The storage box 1 having the storage box 1 is placed on the foundation concrete 7 so that its removal/storage opening 4 is above the ground, and thick backfilling concrete 9 is buried around the storage box 1. They developed a tombstone with a structure in which a pedestal 10 is closely attached to cover the storage opening 4.

<Function> With this structure, the concrete structure around the columbarium serves as a strong foundation to support the pedestal 10.
Since the peripheral edge of the bottom of the tombstone is supported from the bottom, it serves to permanently maintain the stable and vertical state of the tombstone. Furthermore, since the urn storage box has a sealed structure and is corrosion resistant, it prevents the contents from being damaged.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

The tombstone of the present invention shown in the partially cutaway front view of FIG. 1 uses the storage box 1 shown in the perspective view of FIG. 2 as a storage chamber for urns, etc., which has a structure different from that of conventional products. This storage box 1 is composed of a lid part 2 and a container part 3, and has a joint structure in which the lid part 2 and the container part 3 are joined.

The lid part 2 is made of resin laminated structure (about 7 layers) of glass fiber cloth, so-called FRP, and has a size that projects slightly outward from the periphery of the container part 3, and has a rising edge around the middle part in the front in the figure. It has an opening 4 for taking out and storing an urn or the like. The container part 3 is approximately square shaped.
It is an integrally molded product made of FRP (about 3 layers). FRP laminates can contain sheets depicting lotus flowers and leaves, sheets with sutras imprinted on them, sheets with Buddhist paintings, portraits of the deceased, etc., and these can be stored permanently. So,
It is extremely convenient as a storage box.

The opening 4 for taking out and storing the lid 2 is sealed by a cover 5 which is made of the same material as the lid 2 and is pushed over the outside of the rising edge.

Figures 3 and 4 are cross-sectional views for explaining the steps before constructing the tombstone structure of the present invention shown in Figure 1, and Figure 3 shows the state in which the foundation concrete 7 has been poured. , FIG. 4 shows a state in which the storage box 1 is installed on a foundation concrete 7 and the surrounding space is backfilled with backfilling concrete 9.

The size of the hole 6 shown in FIG. 3 almost matches the size of the tombstone pedestal 10 (described later) (it is better to be about 1 to 2 cm larger), and the depth of the hole 6 is at least 20 cm greater than the height of the storage box 1. It has been deleted. This drilling hole 6
Foundation concrete 7 is poured into the bottom of the storage box 1 so that the top surface of the storage box 1 is almost flush with the ground (usually about 2 to 3 cm lower than the ground).

After this, the state shown in FIG. 4 is established, that is, the storage box 1 filled with fine sand 8 is installed, and backfilling concrete 9 is poured into the space around the outer periphery. In this case, the fine sand 8 functions to prevent the storage box 1 from being moved and crushed by the backfilling concrete 9.

The first step is done before the backfill concrete 9 dries.
In the state shown in the figure, the pedestal 10 (a structure divided into two approximately at the center) is installed in close contact with the pedestal 10, and furthermore, prescribed tombstones are built one after another on top of this, and support pillars are placed around the pedestal to maintain the verticality. After curing in step 9, remove the support column.

To remove the fine sand 8 filled in the storage box 1, spread a nylon bag or the like inside the storage box 1 before filling, fill the fine sand 8 into this, and after the concrete hardens, use a bowl-shaped tool to remove the fine sand 8. The fine sand 8 was scraped out from the mouth of the bag, and finally the bag was taken out. Moreover, instead of this fine sand 8, water can also be injected.

Furthermore, if the weight of the tombstone is too large and it is difficult to construct the tombstone before the backfilling concrete 9 hardens, it is sufficient to install only the pedestal 10 horizontally and construct the upper part after the concrete 9 hardens.

The tombstone of the present invention can also have a structure as described below.

In other words, normally the top surface of the storage box 1 is 2 points above the ground.
Although it is installed approximately 3 cm lower, it is backfilled with backfill concrete 9 to a height that is further 3 to 4 cm lower than this upper surface and waits for this to harden. After the concrete 9 has hardened, the pedestal 10 is divided into two parts, so at the time of installation, a total of eight pieces of hard wood with a thickness of about 3 to 4 cm are made using drawn wedges at positions corresponding to the outer corners. , and apply mortar to a thickness of 3 to 4 cm over the entire upper surface of the backfilling concrete 9. A pedestal 10 is placed on this and the horizontality of the pedestal 10 is ensured by pulling out the wedge. In this way, the construction of the upper tombstone is carried out, taking into account the progress of hardening of the mortar and the load resistance of the wedge. The difference from the tombstone structure in the example described above is that mortar and a necessary hard wood wedge are interposed between the backfill concrete 9 and the pedestal 10 to maintain the horizontality of the tombstone and to maintain the level of the tombstone between the pedestal 10 and the underground. The structure is closely integrated with the concrete structure.

In order to ensure the levelness of the pedestal 10 in this way, the concrete structure built underground and the pedestal 10 are secured by pulling out a wedge, rather than by filling it with earth and sand or stone chips as in the past. Since it is completely integrated, similar to the one mentioned above,
This prevents gravestones from tilting.

<Effects of the invention> As detailed above, the tombstone of the present invention has a strong and stable base because the thick backfill concrete foundation around the ossuary box supports the bottom peripheral part of the pedestal from the bottom. Since it has a close contact structure that is integrated with the tombstone, it permanently prevents the tombstone from tilting. Furthermore, since the intrusion and contamination of soil, rainwater, insects, etc. are prevented, the contents of the storage box can be preserved forever.
