Description

  The present invention relates to an earthquake-resistant structure of a tombstone having strong earthquake resistance that does not collapse even when subjected to a large earthquake shake.

Many earthquakes have occurred in various parts of Japan, and many tombstones have collapsed due to the great pitching and rolling of the earthquake. For this reason, for example, a tombstone structure with improved seismic strength has been proposed as in Patent Document 1 and Patent Document 2 below.
In the “gravel seismic device” proposed in Patent Document 1, a connecting hole is passed from the stacked lower turret to the center of the upper meteorite, and a connecting rod is inserted into the connecting hole, and the upper end of the connecting rod is inserted. The structure which fixed the part and the lower end part is disclosed.
Moreover, in the “earthquake-proof device for stone masonry structure and the stone connection method in the masonry structure” proposed in Patent Document 2, the hole for penetrating the connecting rod as described in Patent Document 1 is penetrated to the zenith of the meteorite. The hole that was drilled and stopped halfway from the bottom to the inside of the stone was connected to the connecting hole provided in the center of the lower tombstone, and the connecting rod was inserted through the connecting hole. A structure is disclosed in which the upper portion of the connecting rod is fixed to the hole of the meteorite.

Embodiments of the tombstone earthquake-resistant structure of the present invention will be described below with reference to the drawings.
In the present invention, as shown in FIG. 1, an L-shaped anchor bolt 34 is embedded in a concrete base 32 surrounding a bone chamber 38 dug in the ground by standing a screw portion 35 upright. A cuboid granite turf stand 1 (also referred to as a lower base or a talc) provided with a bolt hole 33 corresponding to the position 34 is placed by inserting the L-shaped anchor bolt 34 into the bolt hole 33.
Then, a nut 37 is screwed and tightened to the thread portion 35 of the L-shaped anchor bolt 34 protruding on the lawn table 1, and the lawn table 1 is firmly fixed on the foundation 32.
At that time, as shown in FIG. 1, a nut concealment hole 36 is provided in the upper end opening upper portion of the bolt hole 33 of the lawn pedestal 1, and a nut 37 is screwed into a screw portion 35 protruding into the nut concealment hole 36. Thus, the bottom stage stone 2a is stably placed in a state where it does not contact the L-shaped anchor bolt 34 and the nut 37 and is in contact with the lawn table 1 without a gap.

On the turret 1, one or a plurality of pedestals 2 (also referred to as an intermediate pedestal or an upper pedestal) are usually stacked. The upper upper stage stone 2b has a size smaller than the lower stage stone 2a, and the upper stage stone 2b and the upper stage stone 2b are used in FIG. Is shown.
The granite is a rectangular granite, and the granite 3 made of granite of a rectangular parallelepiped which is smaller than the upper stage stone 2b but is longer than the upper stage stone 2b (both stone tower and meteorite) Called) is placed. The weight of the meteorite 3 is larger than the lawn table 1 and the stone 2. For this reason, it becomes an unstable structure with a high center of gravity as a whole.
In the lower part of the tombstone, the foundation 32 is hidden underground, but the lawn base 1, the base stone 2 and the meteorite 3 appear on the ground, and the side surfaces of each stone can be seen from the surroundings.
In the present invention, as shown in FIG. 1, a connecting body 5 is vertically arranged at the center of a gravestone made of a hard stone material such as granite piled up as described above, which is composed of the turf stand 1, the talc 2 and the meteorite 3. It is a buried earthquake resistant structure.

The seismic structure of the tombstone will be described in detail below.
As shown in FIG. 2, a perfect circular through-hole 4 is formed in the central part of the lawn base 1 and the base stone 2, as shown in FIG. 2. A locking hole 8 which is vertically raised from the intermediate height to the middle height is provided.
As shown in FIG. 4A, the locking hole 8 is formed with a vertical central hole 8a from the central portion of the bottom surface of the meteorite 3, and the space above the central hole 8a is expanded laterally. Then, an internal expansion space 10 is provided, and side communication grooves 11 are formed on the side wall of the central hole 8a so as to connect from the opening 8b of the meteorite 3 to the internal expansion space 10 at substantially the same depth.

In addition, as shown in FIGS. 1, 3 and 4 (B) and (C), the upper part of the connecting body 5 reaches the internal expansion space 10 of the meteorite 3, and the lower part is the lawn stand. A rotary anchor in which a core body 6a is connected to a bar portion 5a of an iron or stainless steel bar having a length reaching the bottom surface of 1, and a locking piece 12 is integrally formed on the upper portion of the core body 6a. Part 6 is provided.
As shown in (b) and (c) of FIG. 4, the lower part of the rotation anchor part 6 is provided between the bar part 5a and the core body 6a, and the bar part 5a and the core body 6a. An attachment / detachment portion 13 is provided to make the attachment / detachment possible.

Further, as shown in FIG. 4B, a horizontal flange 14 is fixed to the lower portion of the core body 6a of the rotation anchor portion 6.
As shown in FIG. 4A, a flange receiving hole 25 is formed on the bottom surface of the meteorite 3 so that the flange 14 does not protrude from the bottom surface of the meteorite 3. The flange 14 is further provided with a bolt hole 21 facing the installation position of the anchor 20.
Then, as shown in FIG. 1, the anchor bolt 22 is driven into the driving anchor 20 from the bolt hole 21, and the flange 14 is fixed to the bottom surface of the meteorite 3.

As a method of forming the locking piece 12 of the rotating anchor portion 6, the upper end portion of the round bar can be bent and formed by forging. However, as shown in FIG. It is possible to form by various methods such as welding a plate-like piece to each other, or integrally forming the core body 6a with a mold.
And the bolt part 7 is formed in the lower part of the said rod part 5a.

  And the said bar part 5 is penetrated in the center vertical of the said through-hole 4 and the said locking hole 8, and the locking piece provided in the rotation anchor part 6 of the said bar part 5 in that case, as shown in FIG. 12 is rotated to move away from the side communication groove 11 to be locked in the internal expansion space 10 provided in the locking hole 8 in the meteorite 3, and the lawn table 1 is fixed to the bolt portion 7 of the bar portion 5. Tighten the nut 9 from the bottom. If this nut 9 is used in double, it can be fixed more strongly and is difficult to come off.

As shown in FIG. 1, the nut 9 is attached to the bolt part 7 by inserting a metal plate 15 into a hole provided in the center thereof and bringing the bolt part 7 into contact with the bottom surface of the lawn table 1. The nut 9 is fastened to the bolt portion 7 of the rod portion 5a protruding from the hole of the plate 15.
At this time, the connecting body 5 can be pulled down and firmly fastened from the bottom surface of the lawn table 1, and the plate 15 to be used can be strongly tightened without damaging the brittle stone opening. It becomes possible.

In addition to this, as shown in FIG. 1, a lateral misalignment prevention portion 16 can be provided between the lawn base 1, the base stone 2 and the meteorite 3.
The lateral misalignment prevention portion 16 has an upper hole 18 and a lower hole 17 that face the horizontal surfaces facing the upper and lower sides between the stones 1, the stone 2 and the meteorite 3, respectively. A mode in which the stopper member 19 is fitted in the space formed by the hole 17 is possible.
At that time, the stopper member 19 is related to both the upper hole 18 and the lower hole 17, and a slight gap is provided in the upper portion in the space between the two, and the gap formed on the side portion is reduced as much as possible. This is preferable because the lateral displacement is less likely to occur without the stone floating from the underlying stone.

As a result, even if there is a big earthquake, coupled with the vertical fixing of the lawn base 1, the stone 2 and the meteorite 3 by the connecting body 5, the large pitch and roll generated by the earthquake, etc. Because it is possible to obtain high earthquake resistance against shaking occurring in all directions, there is no risk of the tombstones collapsing due to a large earthquake.
In addition to this, since the metal parts such as the bar portion do not protrude at the top of the meteorite 3, the appearance of the entire tombstone is not impaired at all and the appearance is maintained.

Next, the structure of the locking hole 8 of the granite meteorite 3 shown in FIG.
The locking hole 8 is formed by placing the meteorite 3 upside down and drilling a central hole 8a with a diameter of 110 mm at a depth of 170 mm in a vertical direction at the center of the bottom thereof.
Next, using a 100 mm diameter disk-type cutter in which diamond is embedded in a 10 mm wide circumferential surface, the peripheral surface is inserted from the opening of the central hole 8a to near the end of the deepest portion and moved horizontally from the circumferential surface. Then, the inner expansion space 10 is formed by cutting 20 mm laterally at a height of 20 mm.
Next, a hole having a diameter of 60 mm is formed on the peripheral surface of the center hole 8a by using a drill, and the side communication groove 11 is formed by digging a hole having a diameter of 60 mm in the vertical direction from the center of the bottom to the internal expansion space 10. It is formed at two opposing locations.

In this way, the central hole 8a of the locking hole 8 is cylindrical, has a diameter of 110 mm and a depth of 150 mm, and the cylindrical internal expansion space 10 connected to the upper end of the central hole 8a has a diameter of 150 mm and a depth of 150 mm. Further, the side communication groove 11 formed on the side wall of the central hole 8a has a substantially semicircular cylindrical shape that opens the wall surface of the central hole 8a, and a locking hole 8 having a diameter of 60 mm is obtained. It is done.
Further, a circular flange receiving hole 25 having a diameter of 10 mm and a diameter of 202 mm is formed in the opening of the central hole 8a, and the center is shared with the central hole 8a. Driving anchors 20 are provided at four locations.

Next, the structure of the coupling body 5 corresponding to the locking hole 8 will be described in detail with a specific example.
The rod portion 5a of the connecting body 5 is made of stainless steel and has a diameter of 24 mm, and its length is longer than the stacked height of the lawn base 1 and each stone 2 as shown in FIGS. The male screw portion 24 is formed at the upper portion, and the bolt portion 7 is formed at the lower portion.
The rotating anchor portion 6 is formed by welding a metal flange 14 having a thickness of 10 mm and a diameter of 200 mm to a lower portion of a cylindrical core body 6 a having a diameter of 100 mm and a length of 150 mm made of metal such as iron. Then, a female screw portion 23 that can be screwed from the lower surface of the metal flange 14 to the male screw portion 24 at the upper portion of the rod portion 5a is formed to an intermediate height in the core body 6a. That is, the male screw portion 24 of the rod portion 5a can be attached to and detached from the female screw portion 23.
The flange 14 is provided with a screw hole 21 in a portion corresponding to the driving anchor 20 in the flange receiving hole 25 of the meteorite 3.

When an anchor bolt 22 having a diameter of 4 mm and a length of 1.5 mm is driven from the screw hole 21 into the driving anchor 20, as shown in FIG. 1, the flange 14 of the rotating anchor portion 6 is connected to the locking hole. 8 is firmly fixed in the flange receiving hole 25 provided with the opening.
If one nut is attached to the female screw portion 23 before the male screw portion 24 of the rod portion 5a is screwed to the female screw portion 23, the rod portion 5a of the connecting body 5 is placed in the middle. After screwing onto the core body 6a, the nut is further tightened to prevent the rod portion 5a from rotating with respect to the center core body 6a, thereby making it possible to fix them more reliably. In this case, an opening in the upper part of the four through-holes 4 of the upper stage stone 2b is formed so that the bolt can be fitted, so that the meteorite 3 can be placed horizontally on the bed stone 2. .
Then, as shown in FIG. 4B, a locking piece 12 made of a metal plate having a thickness of 10 mm is provided on the upper portion of the core 6a so as to protrude 24 mm laterally from the peripheral surface of the core 6a. Secure integrally by welding.
As shown in FIG. 4B, the shape of the locking piece 12 is such that the locking hole 8 can be passed through the semicircular side communication groove 11 having a diameter of 30 mm. Is a small semicircle with a diameter of 24 mm.

  The principle by which the rotating anchor portion 6 is locked in the locking hole 8 will be described with reference to (2) of FIG. 4. The locking hole 8 shown in (2) a of FIG. ) As shown in b, the locking piece 12 passes through the side communication groove 11 to the deepest part of the central hole 8a, where it is locked by a slight angle rotation as shown in FIG. The piece 12 rides on the bottom surface of the internal expansion space 10 and cannot be pulled out. Further, as shown in FIG. 4 (2) d, when the side communication groove 11 is rotated to an intermediate position between the side communication groove 11 and another side communication groove 11 which is different from the side communication groove 11, the locking piece is reliably removed from the internal expansion space 10. 12 will not come off.

The locking piece 12 is formed on the peripheral surface of the core body 6a corresponding to the number and position of the side communication grooves 11, but in the case of the one shown in FIG. 5 (b), 2 cases shown in FIG. 5 (c), 3 cases shown in FIG. 5 (d), 4 cases shown in FIG. 5 (d), and 5 cases (not shown) ) Is possible.
The shape of the locking piece 12 may be any shape that allows the side communication groove 11 to pass up and down. In the figure, a semicircular shape corresponding to the side communication groove 11 is shown. Various shapes such as a rectangular shape (not shown) or a quadrangular shape (not shown) are possible. In the present invention, the shape of the horizontal cross section of the side communication groove 11 and the planar shape of the locking piece 12 are the above shapes. It is not limited.
And in order to make it difficult to remove | deviate, all the rotation positions at the time of latching the latching piece 12 stop at the intermediate position of the side part communication groove 11 and the other side part communication groove 11 different from it. The position where the part communication groove 11 is uniformly separated is stopped. For example, the rotation is 90 degrees in the case of two, 60 degrees in the case of three, and 45 degrees in the case of four.

  There are various other structures that can be locked in the internal expansion space 10 of the locking hole 8 in the meteorite 3 by rotating the locking piece 12 on the upper part of the connecting body 5 as described above. 6, 7 and 8 are possible and will be described below.

For example, the form shown in FIG. 6 is a form in which the flange 14 is not provided in the rotation anchor part 6 in the form shown in FIG. 4 as shown in FIG.
In this embodiment, some instability occurs when the rotation anchor portion 6 is attached to the locking hole 8 of the meteorite 3.
For this reason, before placing the meteorite on the bedrock, a filler such as cement or epoxy is injected into the locking hole 8 between the locking anchor 6 and the rod portion 5 before on-site construction. Is firmly fixed by the meteorite 3, and the state in which the locking piece 12 is locked in the internal expansion space 10 is held.

  Even in this configuration, the rotation anchor portion 6 is locked in the locking hole 8 as described in (2) of FIG. 6, in the locking hole 8 shown in (2) a of FIG. As shown in FIG. 6 (2) b, the locking piece 12 enters the deepest part of the central hole 8a through the side communication groove 11, where there is a slight angle as shown in FIG. 6 (2) c. When it is turned, the locking piece 12 rides on the bottom surface of the internal expansion space 10 and cannot be pulled out. Further, as shown in FIG. 6 (2) d, when the side communication groove 11 is rotated to an intermediate position between the side communication groove 11 and another side communication groove 11 which is different from the side communication groove 11, the locking piece is reliably removed from the internal expansion space 10. 12 will not come off completely.

  Further, for example, in the form shown in FIG. 7, as shown in FIGS. 7 (a) and 7 (c), the internal expansion space 10 of the locking hole 8 of the meteorite 3 is replaced with the upper internal expansion space 26 and the intermediate internal expansion space. Two spaces 27 are formed at the upper end portion and the middle height portion of the central hole 8a. Further, as shown in FIGS. The stop piece 12 is made into two places, the upper stage locking piece 30 and the middle stage locking piece 31, and this is a part corresponding to the upper internal expansion space 26 and the lower internal expansion space 27 of the center core portion 6 a of the rotation anchor portion 6. Further, the side communication groove 11 of the locking hole 8 is provided with an upper side communication groove 28 and a middle side so that the upper stage locking piece 30 and the middle stage locking piece 31 can simultaneously pass to the deepest part. A part communication groove 29 is formed.

  In this form, the upper internal expansion space 26 and the lower internal expansion space 27 of the locking hole 8 of the meteorite 3 are formed at two positions in the upper end portion and the intermediate height portion to form two steps. Separately, a plurality of three or more stages are formed in different upper and lower stages, and the locking piece 12 of the bar portion 5 is locked to the corresponding portion of the center core portion 6a of the rotating anchor portion 6 according to the formation position. By providing the piece 12, it is also possible to rotate the bar portion 5 and simultaneously lock it in the internal expansion space 10 in multiple stages.

In addition, the protruding direction of the locking piece 12 may be the same for each stage, but it is possible to change the angle of the protruding direction. In FIG. 7, the angle in the protruding direction between the two upper locking pieces 30 and the middle locking pieces 31 is changed by 90 degrees.
Further, it is possible to adopt a mode in which the number of the remarkably locking pieces 12 is remarkably different from each other.
As for the form of these locking pieces 12, the rod portion 5 can be locked more firmly to the meteorite 3 when the number is usually more than one, but if the interval is narrow, the stone material will break. It is not just a matter of increasing the number.
Corresponding to the strength determined by the size of each part of the rotating anchor part 6 and the material of the meteorite 3 having different material strengths, the best mode capable of maintaining the high pulling strength of the rotating anchor part 6 can be selected. Is possible.

Further, for example, in the form shown in FIG. 8, as shown in FIGS. 8A and 8B, the locking hole 8 of the meteorite 3 includes two opposing side communication grooves 11, In this embodiment, two locking pieces 12 are formed on the upper portion of the bar portion 5 so as to be able to pass through the two side communication grooves 11.
In construction, the rod part 5 must be fixedly attached to the meteorite 3 before being inserted into the lawn base 1 and the base stone 2. Since an integral material that is not separated from the rod portion 5a is used, the structure is simpler than the above embodiments, and the cost can be kept low.

  Also in this embodiment, the process of locking the rotating anchor portion 6 in the locking hole 8 will be described with reference to (c) in FIG. 8 (c) b, the locking piece 12 passes through the side communication groove 11 to the deepest part of the central hole 8a, and there is a slight angle rotation as shown in FIG. 8 (c) c. When moved, the locking piece 12 rides on the bottom surface of the internal expansion space 10 and cannot be pulled out. Further, as shown in FIG. 8 (d) d, when the side communication groove 11 is rotated to a middle position of 90 degrees between the side communication groove 11 and another adjacent side communication groove 11, it is locked from the internal expansion space 10. The piece 12 is engaged, and the connecting body 5 cannot be completely removed from the meteorite 3.

  The seismic structure of the tombstone according to the present invention is to integrally fix the uppermost meteorite, the lower lawn pedestal, and all the trapezoids between them with a connecting body, but the shape of the tombstone is shown in each figure. It can be widely used for gravestones having various shapes such as stones having various decorations on the surface, except when a rectangular parallelepiped is used.
