However, when the block rod 275 is only one, the receiving pipe 286 and the horizontal member 287 are omitted. To do. In this case, the underground passage 276 may be omitted.

図７および図８は付加的な提案例を示し、同提案例は、和式墓石（灯篭・重い土台・モニュメント・建物などを含む）の地震対策についてのものである。
例えば、墓石は、図７に示すように、墓所２９３の地盤２９４内に礎石２９５を枠組み状に埋設固定し、その上に下台（芝石）２９６・中台２９７・上台２９８・仏石（竿石）２９９の順に積み重ねをして建立されるのが一般的である。礎石２９５の底には敷石３００…を配して基礎固めをして墓石の安定化を図るようにしているが、従来は、この敷石３００が丸石とされていたため、地震時の衝撃負荷が加わると飛び散る傾向となって隙間ができたりして墓石が傾いたり倒れたりしていた。7 and 8 show additional proposal examples, which are related to earthquake countermeasures for Japanese style tombstones (including lanterns, heavy foundations, monuments, buildings, etc.).
For example, as shown in FIG. 7, the tombstone has a foundation stone 295 embedded and fixed in the ground 294 of the tomb 293, and a lower platform (turfstone) 296, middle platform 297, upper platform 298, Stone) It is generally built by stacking in order of 299. The stones 295 are placed on the bottom of the foundation stones 295, and the foundations are hardened to stabilize the tombstones. However, since the stones 300 were conventionally cobblestones, an impact load was applied during an earthquake. The tombstones were tilted and fell down as a result of the tendency to scatter.

この提案例は、敷石３００が地震時にスプリングの作用をして衝撃負荷を吸収することで隙間もなく現状維持機能を果たすようにすることができて墓石に被害が出ないようにした。そのため、敷石３００として図７の右下欄および図８の右欄に取り出して示すように割石（切石）を採用したものである。３０１は内仕切り、３０２は外仕切りでそれぞれ墓所内に四角枠状に埋設され、その内外間および外仕切り３０２の外周に敷石３００を配備して固め、それらの上に礎石２９５を設置したものである。  In this proposed example, the paving stone 300 acts as a spring in the event of an earthquake and absorbs an impact load, so that the current maintenance function can be performed without a gap, so that the tombstone is not damaged. For this reason, as the paving stone 300, slabs (cut stones) are adopted as shown in the lower right column of FIG. 7 and the right column of FIG. 301 is an internal partition, 302 is an external partition, each embedded in a square frame in the tomb, and a paving stone 300 is placed between the inside and outside and the outer periphery of the external partition 302 and hardened, and a foundation stone 295 is installed on them. is there.

従って、図７に示すように、地震時にＸおよびＹ方向のいずれの方向からの衝撃負荷に対してもスプリング作用で有効に墓石を護ることができる。尚、図７の右欄に示すように敷石３００は軽石であってもよい。また、割石にはゴム材やレンガなどを適宜に混合することがある。
また、図９に示すように、地震対策のため、墓石の上下間には対応する個所に嵌装凹所３０４を形成しておき、これら両凹所３０４内を介して結合ピン３０５を嵌め込んでもよい。この結合ピン３０５は、ステンレス・木材・チタンなどが使用されるが、図９の右欄に示すように、溝３０６を有するもので圧入されるものにすれば墓石の上下各間が非常に安定結合する。この結合ピン３０５の上下端部は面取り状にすれば嵌め込み作業がしやすくなる。Therefore, as shown in FIG. 7, the tombstone can be effectively protected by the spring action against an impact load from either the X or Y direction during an earthquake. As shown in the right column of FIG. 7, the paving stone 300 may be pumice. In addition, rubber materials and bricks may be appropriately mixed with the quarry stone.
Further, as shown in FIG. 9, as a countermeasure against earthquakes, fitting recesses 304 are formed at corresponding locations between the upper and lower sides of the tombstone, and the coupling pins 305 are fitted through these recesses 304. But you can. This coupling pin 305 is made of stainless steel, wood, titanium or the like. However, as shown in the right column of FIG. Join. If the upper and lower end portions of the coupling pin 305 are chamfered, the fitting operation is facilitated.
