Description

  The present invention relates to a grave that has a structure that does not easily fall down in the event of an earthquake or the like and has excellent earthquake resistance.

  Conventionally, as a grave of this kind, for example, a technique described in Japanese Utility Model Registration No. 3031749 is known. As shown in FIG. 3, this tomb 100 is made of hard stone material such as granite and andesite, and has a rectangular flat cross-section and three simple stones of which the area of the flat cross-section decreases in order from the bottom. The top single stone is formed as a rock stone 101, the single stone on which the rock stone 101 is mounted is defined as an upper table 103, and the single stone on which the upper table 103 is mounted is defined as a lower table 106. .

In this grave, fitting holes 109 facing each other are formed in the lower end portion 102 of the rod 101 and the top surface 104 of the upper stand 103, and the lower end portion 105 of the upper stand 103 and the top surface 107 of the lower stand 106 are opposed to each other. A fitting hole 109 is formed, and a columnar or prism-shaped hookstone 110 formed of a hard stone material such as granite or andesite is fitted into the fitting hole 109 and bonded with an adhesive.
Thereby, even when the tomb shakes in the event of an earthquake or the like, the rock stone 101 and the upper base 103 are prevented from falling down due to the shearing force of the hook stone 110.

Registered Utility Model No. 3031749

  By the way, in this conventional tomb 100, the rod 101 and the upper table 103 are connected by fitting with a hook 110, and the upper table 103 and the lower table 106 are connected by fitting with a hook 110. Since it is a rod-shaped and small one, its allowable shear force and allowable bending stress are not necessarily high. Therefore, when an earthquake or the like occurs, the hook stone 110 cannot withstand vibration and breaks, and the connection is not necessarily strong. Therefore, there is a problem that the grave 100 may fall down and collapse.

  The present invention has been made in view of the above problems, and combines the upper and lower single stones so that their allowable shear force and allowable bending stress are increased, improving stability, making it difficult to fall down, The purpose is to provide a grave with improved earthquake resistance.

The technical means of the present invention for achieving such an object is as follows: in a grave formed by sequentially placing a plurality of simple stones having a smaller plane area in order from the bottom on each simple stone, A concave portion is formed in the simple stone to fit the lower end of the upper simple stone.
As a result, the lower end of the single stone to be fitted is thicker, so that the allowable shear force and allowable bending stress can be increased as compared with the conventional bar-shaped hookstone, and the stone can be subjected to an earthquake or the like. When it occurs, the single stone does not easily fall over or skid, and the earthquake resistance is improved.

  Further, if necessary, the depth D of the recess is set to D ≧ 150 mm. Pressing by the wall surface of the concave portion is ensured, and the single stone is less likely to overturn or slide, and the earthquake resistance is improved.

Then, if necessary, the flat cross-sectional area of a single stone upper S _1, a flat cross-sectional area of a single stone lower one of said upper when the S _2, has a configuration in which the S ₂ ≧ 4S _1. Since the plane cross-sectional area of the lower unit stone is four times or more larger than that of the upper unit stone, even if a heavy upper unit stone is fitted, the support is assured. The holding by the wall surface of the solid stone is more reliable, and the falling of the single stone and the side slipping are less likely to occur, and the earthquake resistance is improved.

  Further, if necessary, the flat cross section of each of the simple stones is formed in a rectangular shape, and the concave portion is formed at the center of the simple stone when viewed from above. Since the upper simple stone is located at the center of the lower simple stone, even if the heavy upper simple stone is fitted, it can be supported in a well-balanced manner. Further, the single stone is less likely to overturn or skid, and the earthquake resistance is improved.

The tomb according to the present invention is specifically formed by sequentially placing three simple stones having a rectangular flat cross section and the area of the flat cross section decreasing sequentially from the bottom on each single stone, In the tomb with the simplest stone on which the highest stone is placed as a rock, and the single stone on which the rock is mounted as the upper base, and the lower base with the simple stone on which the upper is mounted, the upper base is located at the center when viewed from the plane. The lower end of the rod stone forms a recess for fitting, the lower platform has a recess in which the upper platform fits in the center when viewed from the plane, and the depth dimension D of each recess is D ≧ 150 mm, When the flat cross-sectional area of the rock stone is S ₁ and the flat cross-sectional area of the upper stand is S ₂ , S ₂ ≧ 4S ₁ .

  In this way, in a grave formed by placing three simple stones on each simple stone in order, even if the rock stone and the upper stand are shaken sideways and fall down when an earthquake or the like occurs, the conventional rod-shaped Compared to hook stones, the lower end of the single stone to be fitted is thicker, so that the allowable shear force and allowable bending stress can be increased to combine the single stones, and the depth of each recess is D ≧ 150mm, the pressing by the wall surface of the concave part is reliable, and the size of the flat stone of the lower simple stone is more than 4 times larger than that of the upper simple stone. Even if the upper simple stone is fitted in the middle of the lower simple stone, the upper simple stone is positioned at the center of the lower simple stone, so that it can be supported in a well-balanced manner even when the heavy simple stone is fitted. This makes it possible to securely hold down the wall of the recess, Hardly occur tipping or side slip or the like, vibration resistance is improved.

  According to the grave of the present invention, since the lower end of the single stone to be fitted is thick, it can be connected with a higher allowable shear force and allowable bending stress than the conventional rod-shaped hook stone. For this reason, when an earthquake or the like occurs, the single stone does not easily fall over or side-slip, and the seismic resistance can be significantly improved.

Hereinafter, a tomb according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a tomb G according to an embodiment of the present invention. The tomb G is made of a stone material such as granite and andesite, has a rectangular flat cross section, and sequentially places three simple stones 1 having a smaller flat cross section area from the bottom on each single stone 1. It is formed.
The simplest stone 1 at the top is a rock stone 2, the simple stone 1 on which the rock stone 2 is placed is an upper stand 3, and the simple stone 1 on which the upper stand 3 is placed is a lower stand 4.

In this tomb G, a concave portion 6 in which the lower end portion 5 of the rock stone 2 is fitted is formed in the center of the upper base 3 when viewed from the plane, and a concave portion 6 in which the upper base 3 is fitted in the center when viewed from the flat surface. Is formed.
Further, when the depth dimension D of each recess 6 is D ≧ 150 mm, the plane sectional area of the rod 2 is S _1, and the plane sectional area of the upper base 3 is S ₂ , S ₂ ≧ 4S ₁ . In the embodiment, S ₁ = 300 × 300 = 90000 mm ² and S ₂ = 600 × 600 = 360,000 mm ² . The depth D of the recess 6 is set to D = 150 mm.

  Therefore, when constructing the tomb G according to the embodiment, as shown in FIGS. 1 and 2, the lower base 4 is first installed, and then the lower end 5 of the upper base 3 is fitted into the recess 6 of the lower base 4. The rock stone 2 is fitted into the concave portion 6 of the upper base 3 and installed. In this case, the grave G can be constructed only by fitting the stones sequentially from the lower base 4, so that the construction is extremely simple.

  According to the grave G, when an earthquake or the like occurs, even if the rock stone 2 and the upper base 3 swing sideways and try to fall down, the lower end portion 5 of the fitted single stone 1 is thick, so that the allowable shear force and The simple stone 1 can be joined by increasing the allowable bending stress, and since the depth of each recess 6 is set to D ≧ 150 mm, the pressing by the wall surface of the recess 6 is ensured. Since the size of the flat cross-sectional area of the lower unitary stone 1 is four times or more larger, even if the heavy upper unitary stone 1 is fitted, the support is assured. Since the stone 1 is located at the center of the lower unitary stone 1, even if the heavy upper unitary stone 1 is fitted, the stone 1 can be supported in a well-balanced manner. The single stone 1 is less likely to overturn or skid, improving seismic resistance Is Sera.

  In the above-described embodiment, the single stone 1 is provided in three steps, but the present invention is not necessarily limited to this, and may be two steps or four or more steps, and may be changed as appropriate. .
