Description

  The present invention relates to a tomb structure that prevents dripping of condensed water in the ossuary chamber and intrusion of rainwater into the ossuary chamber.

  Japan's tombs are made by stacking stones called foundations, boxes, upper bases, and coffins. As a method of creating an ossuary chamber inside the stacked tombstones, in the old days, the structure of forming the ossuary chamber by closing the upper surface of the stone provided with a void penetrating up and down with stones stacked on it was common, With the widespread use of a machine that pierces a stone and a machine that polishes the inner surface, a structure that forms a ossuary chamber that is called a box and has a ceiling integrally formed by making a square bottom surface of the stone is known. An opening for receiving a bone is provided on the front surface of the box.

  The box is placed on a stone called a base with a square through-hole in the center, and is made of stone that is integrated with the bottom of the soil and the side wall by the through-hole in this base and the space drilled in the box. A ossuary chamber with a ceiling surface is formed. On the base, an incense stand and a flower stand are installed in contact with the front of the box, and the opening provided on the front of the box is closed by these stone materials.

  Japanese tombs are made on the basis of hexahedral shapes such as square holes and prisms, and the space provided in the box 1 to form the ossuary chamber is also hexahedral. That is, they are formed by front and rear wall surfaces that are parallel to each other and horizontal ceiling surfaces that are orthogonal to these wall surfaces.

In addition, as a structure to prevent rainwater from entering the ossuary chamber, the ridge surrounding the through hole is cut out integrally on the upper surface of the peripheral edge of the through hole of the base, and the empty space of the box is placed outside this ridge. As a fitting size, even if rainwater enters the joint between the foundation stone 6 and the box 1, a structure is provided in which the rainwater is prevented from flowing into the ossuary chamber by the protrusions.

  In the tomb of the conventional structure as described above, water droplets condensed on the ceiling surface of the ossuary chamber are dropped onto the urn etc. stored in the ossuary chamber. In addition, the protrusions in the conventional waterproof structure need to scrape the entire upper surface of the base by the height of the protrusions, leaving the periphery of the hole that becomes the osteotomy chamber, and there are irregularities and undulations on the scraped surface. Then, the box or flower stand placed on this will rattle or create a gap between it and the base, so it must be scraped off to an accurate plane. Although this operation is performed using a sander or the like, there is a problem that requires a great amount of labor.

  The present invention has been made to solve the above problems, and water condensed on the ceiling of the ossuary chamber is led out of the tombstone without dripping onto the urn etc. The object is to provide a tomb structure that prevents rainwater from entering the ossuary chamber through the gap between the box and flower stand.

In this invention, the dripping of condensed water from the ceiling surface of the ossuary chamber is prevented by making the ceiling surface 3a of the space 2 drilled in the stone material 1 which becomes a box into a dome-shaped medium-high surface. That is, the condensed water condensed on the ceiling surface of the ossuary chamber flows downward along the slope and arc surface before dropping, and flows down along the inner wall surface. Can be prevented.

The grave according to the invention of claim 1 of the present application is a grave where a void 2 having a ceiling surface is formed from the bottom surface of a stone (box) 1 stacked on a base and the void is used as a ossuary chamber. where 2 of the ceiling surface 3a is Ri highest convex surface der domed flowing a concave surface from the central portion to the four directions, the ceiling surface 3a of the dome shaped, smooth inner wall 4 surrounding the circular arc surface 3b It is characterized by being connected to .

The shape of the ceiling surface, condensed water is most preferably shaped to reach the inner wall surface in the shortest distance, de chromatography domed you inclined in four directions is the best. Condensed water aggregates the condensed water on the flow path while flowing along the ceiling surface, and it becomes easy to fall. Therefore, considering this point, the dome has a steep slope near the inner wall surface. Shape is preferred.

In the tomb of the preferred structure, a circumferential groove 9 is engraved on the upper surface around the square through hole 7 which is the lower half of the ossuary chamber formed in the foundation stone 6 with the inner wall 8 left between the through hole 7. and, Keru set the through hole 10 and Tsumizo 11 communicating with the bottom surface or the outer circumferential surface of the foundation stone 6 from the circumferential groove.

That is, the foundation stone 6 provided with the through hole 7 communicating with the void 2 drilled in the bottom surface of the box 1 is cut with the inner wall 8 remaining between the through hole and the upper surface around the through hole. a circumferential groove 9 which is a bottom or outer peripheral surface of the foundation stone 6 from the circumferential groove, preferably a through hole 10, 12 to Tsumizo 11 communicating with the lower side to the lower back, the box 1, the cavity The peripheral edge 4 a at the lower end of 2 is positioned within the groove width of the circumferential groove 9 of the foundation stone 6 and is stacked on the foundation stone 6 .

  The circumferential groove 9 is provided at a position where the center of the groove width coincides with the periphery of the lower end of the space 2 provided in the box. At least the lower end periphery of the space 2 is provided so as to be positioned within the groove width of the peripheral groove 9 over the entire periphery. Although there is no particular problem even if there is an error that the lower edge 4a is slightly displaced outside the circumferential groove 9, an error in a direction that is displaced toward the inside of the circumferential groove 9 should be avoided.

With this structure, the dew condensation water that has flowed down along the inner peripheral surface of the void 2 is guided to the peripheral groove 9 and passes through the through hole 10 and the through hole 12 or the through groove 11 to the bottom surface or the outer periphery of the foundation stone 6. Drained. Further, the water that has entered the ossuary chamber side from between the upper surface of the foundation stone 6 and the box 1 is trapped by the circumferential groove 9 and discharged through the through hole 10 and the through hole 12 or the through groove 11 like the dew condensation water. Is done. Therefore, it is possible to prevent rainwater and the like from entering the ossuary chamber together with the drainage of condensed water.

The top surface of the inner wall 8 of the circumferential groove provided on the foundation stone 6 is the same height as the foundation upper surface of the outer circumferential portion of the circumferential groove. That is, as in the conventional structure, there is no need to remove the entire top surface of the base stones 6, may only delete a circumferential groove 9 parts, so further does not require a high flatness of the bottom and walls of the circumferential groove, easily Can be processed. The through holes 10 and 12 and the through groove 11 can also be easily processed using a boring device or a grooving device.

According to the invention of claim 1 of the present application, the dew condensation water in the ossuary chamber can be prevented from dripping onto the urn etc. stored in the ossuary chamber, and is used in combination with a structure for preventing rainwater from entering the ossuary chamber. Thus, there is an effect that the condensed water can be discharged out of the ossuary chamber.

  The invention will now be described with reference to the drawings showing some of the preferred embodiments of the invention.

  FIG. 1 is a perspective view showing the most preferred form of the box, and FIGS. 2 and 3 are a cross-sectional side view and a cross-sectional front view of the central portion of the box shown on the foundation stone. The broken line in FIG. 1 is a line indicating the shape of the void formed inside.

  The box 1 is formed with a space 2 which is formed in a rectangular shape from the bottom side and becomes the upper part of the osteotomy chamber. As clearly shown in FIGS. 2 and 3, the ceiling 3 of this empty space has a dome shape that flows in a concave curved surface from the highest central part to the four directions. The dome-shaped ceiling surface 3a is smoothly connected to the surrounding inner wall surface 4 by a circular arc surface 3b. On the front surface of the box 1, an opening 5 is provided for storing an urn or the like in an ossuary chamber.

  FIG. 4 is a perspective view of the foundation stone, and FIG. 5 is a cross-sectional front view of a portion provided with drainage through holes and through grooves. As shown in FIGS. 2 and 3, the box 1 is placed on the foundation stone 6.

  A square hole 7 that is located slightly behind the center of the foundation stone 6 and forms the lower part of the ossuary chamber is provided so as to penetrate vertically. The area of the square hole 7 is smaller than the area of the empty space 2 of the box.

  A peripheral groove 9 is cut around the square hole 7 leaving an inner wall 8 having a thickness that does not cause chipping or cracking. The four corners of the circumferential groove 9 are provided with circular through holes 10 in the vertical direction passing through the foundation stone 6 with the center shifted slightly outward from the center of the circumferential groove 9. Further, on the lower surface of the foundation stone 6, a through groove 11 is cut from the lower end of the through hole 10 toward the outside in the left-right direction of the foundation stone. The front end of the through groove 11 is open to the bottom of the side surface of the foundation stone 6.

  As shown in FIGS. 2 and 3, when the box 1 is placed on the foundation stone 6, the circumferential groove 9 has a groove width of the circumferential groove 9 so that the peripheral edge 4 a at the lower end of the space 2 of the box extends over the entire circumference. It is provided so that it may be located inside. In practice, an error occurs during processing and stacking of stones. Therefore, if the dimension is such that the lower end peripheral edge 4a of the void is located at the center of the width of the groove width 9, the margin of error can be maximized. The foundation stone 6 is placed on gravel on the ground of the grave or on the concrete foundation.

  In some cases, as shown in FIG. 6, a relatively wide circumferential groove 9 is provided in the base stone 6, and the inner wall surface is the same as the inner wall surface of the space 2 at the lower edge 4 a of the space 2 of the box. It is also possible to provide a structure in which the surrounding fence 13 is provided and the box 1 is stacked on the foundation stone 6 in a state where the surrounding fence 13 enters the circumferential groove 9. At this time, the circumferential flange 13 is inserted between the inner wall 8 of the circumferential groove 9 with a margin. Since the height of the peripheral rod 13 may be much lower than the protrusion for preventing rainwater from entering in the conventional structure, the processing is relatively easy.

  When the box 1 is placed on the foundation stone 6 in the positional relationship as described above, the condensed water flowing down along the inner wall surface 4 of the box flows into the circumferential groove 9 of the foundation stone and passes through the through hole 10. Flow down. When the foundation is installed on the gravel, it flows down into the gravel gap as it is, and when it is installed on the concrete foundation, it flows through the through-groove 11 to the side of the foundation stone. In order to make the flow of water from the circumferential groove 9 to the through hole 10 smooth, it is preferable to provide a water gradient toward the through hole 10 on the bottom surface of the circumferential groove 9.

  When there is windy rain, rainwater that has fallen on the upper surface of the foundation on the windward side flows through the gap between the foundation stone 6 and the box 1 toward the bone chamber. However, since this rainwater flows down into the circumferential groove 9 and cannot pass through the inner wall 8, it is discharged out of the tombstone through the through hole 10 and the through groove 11 like the condensed water. The surrounding fence 13 in the structure shown in FIG. 6 more reliably prevents the inflow of rainwater during wind and rain. However, even if such a surrounding fence is not provided, the bone is passed through the stack surface of the foundation stone 6 and the box 1. Rainwater does not enter the room.

  The above example is a structure that drains to the bottom surface or the side surface of the foundation stone 6, but FIGS. 7 and 8 are drained to the back surface of the foundation stone 6 through the condensed water and rainwater through holes 10 and 12 captured in the circumferential groove 9. This is an example. In this example, through holes 10 are provided at two corners on the grave back side of the circumferential groove 9, the through holes 10 are bottomed holes, and horizontal through holes 12 drilled from the back of the foundation stone pass through. It communicates with the bottom of the hole 10. The circumferential groove 9 is provided with a water gradient from the front to the rear, and the water that has flowed down to the front portion of the circumferential groove 9 is also guided to the rear of the circumferential groove 9 and discharged to the lower back portion of the foundation stone 6.

  Thus, the through-holes 10, 12 or the through-groove 11 can be provided obliquely in a free position and direction, for example, from the position of the circumferential groove toward the lower part of the outer peripheral surface, depending on the conditions of the place where the grave is installed What is necessary is just to select suitably.

  The shape of the circumferential groove cross section formed in the foundation stone 6 may be any shape such as a U shape, a U shape, and a V shape. The positions and the number of the through holes 10 and the through grooves 11 are not particularly limited, but structures provided at the four corners or two corners on the back side of the grave are most reasonable in terms of the number of processing and smoothness of drainage. The through groove 11 is provided toward the side surface or the back surface. In addition, it is not necessary to provide the through-groove 11 in the foundation stone installed on the gravel mentioned above.
