Description

  The present invention relates to a seismic device for a masonry structure that can prevent masonry structures such as tombstones, lanterns, and stone monuments constructed by stacking stone materials from collapsing due to seismic force.

  Masonry structures such as tombstones and lanterns, which are constructed by stacking stones in sequence, have a problem that they can easily collapse if the seismic force is particularly large, simply by stacking stones in surface contact. For this reason, as means for preventing the collapse of such gravestones, earthquake-resistant devices disclosed in JP-A-10-37532 and JP-A-9-137638 have been proposed.

  As shown in FIG. 41, the former seismic device (Japanese Patent Laid-Open No. 10-37532) has a lower base b placed on a foundation a and a middle base c placed on the lower base b. An upper base d is placed on c and a meteorite e is placed on the upper base d, and support through bolts f erected at the four corners of the foundation a are connected to the lower base b and the middle The nut k is inserted into the screw shaft portion at the upper end of the bolt that is inserted through the insertion holes g, g that are vertically penetrated at the four corners of the base c, and protrudes from the concave portion i that is concaved on the upper surface h of the middle base c. The upper base d is placed so as to be screwed and tightened and to cover the recess i. Further, a connecting rod n is inserted into through holes m, m that are vertically connected to the upper base d and the meteorite e, and male screw portions p, q at the upper and lower ends of the connecting rod n are provided. The lower through-hole m is projected at the lower end and the upper through-hole m at the upper end. Then, the nuts t and u are screwed and tightened to the protruding male screw shafts p and q so as to integrate the ceiling portion v of the intermediate platform c, the upper platform d and the entire meteorite e, As a result, the entire tombstone w was integrated to improve the earthquake resistance of the tombstone.

  By the way, when using such an earthquake-resistant device, the through hole m through which the connecting rod n passes is opened at the upper end x of the uppermost stone (meteorite e), so that it is fastened to the male screw portion p at the upper end of the connecting rod n. In addition, there is a problem that the nut t is exposed to impair the beauty of the tombstone. Therefore, in order to prevent this, as shown in an enlarged view in FIG. 42, a concave portion y for accommodating the nut t is provided in the upper end surface of the meteorite e, and a cap z is placed so as to cover the nut t, and In order to improve the water tightness, the inside is filled with mortar a1.

  However, even when the cap z is covered and the mortar a1 is filled in order to improve the water tightness, rainwater may permeate into the cured portion b2 of the mortar and enter the through hole m within a long period of time. As a result, there arises a problem that the corrosion resistance of the tombstone is deteriorated due to the corrosion of the connecting rod n. Also, rainwater enters from the contact portion c1 between the middle platform c and the upper platform d, and rainwater enters the through hole g provided in the ceiling portion v, whereby the support through bolt f is corroded. The problem of degrading the earthquake resistance of the tombstone occurred.

  Further, since water easily collects in the concave portion y of the meteorite e, moss grows around the cap z, and dirty water flows from the upper surface d1 to the side surface e1 of the meteorite e. There is a problem that it is difficult to remove the dirt.

  Furthermore, providing the through hole m or covering the cap z in the meteorite e in this way makes it particularly impressing that the tombstone is seismic design, and makes the appearance of the tombstone unnatural. There was also.

  Also, when repairing the foundation of the tombstone tilted by the seismic force or when repairing the seismic coupling device, the nut t at the upper end of the coupling rod n is removed to remove the meteorite e and the upper base d, and the support It is necessary to remove the nut k at the upper end of the through bolt f to remove the middle base c and the lower base b, and there is a problem that the construction work for removing the individual stone materials in order requires a lot of labor and time and the workability is poor. It was.

  In addition, when assembling tombstones, the stones were simply stacked in contact with each other, so it was difficult for specialists to locate the tombstone. There was also a problem that required a lot of labor and time for construction work.

  On the other hand, as shown in FIG. 43, the latter seismic device (Japanese Patent Laid-Open No. 9-137638) includes a female screw portion h1 embedded in the bottom g1 of the uppermost stone (meteorite) f1, and this female screw portion h1. A connecting rod k1 having a screw shaft portion j1 which can be screwed to the upper end, and an elastic pipe m1 fitted on the outer periphery of the portion excluding the screw shaft portion j1 of the connecting rod k1, and the female screw portion The screw shaft portion j1 of the connecting rod k1 whose outer periphery is covered with the elastic pipe m1 is screwed and connected to h1, and the connecting rod k1 covered with the elastic pipe m1 is positioned on the lower side. The mortar r1 is inserted into the through hole n1 provided in the stone, and then inserted into the bottomed hole q1 formed in the stone p1 at the lowermost end, and then poured into the through hole n1 and the bottomed hole q1. The elastic pipe m1 is fixed to the stone material p1 by It was composed sea urchin. The bottom end portion s1 of the connecting rod k1 is formed with a flat surface t1 that is obliquely cut, and the bottom end portion s1 protrudes from the elastic pipe m1 into the bottomed hole q1. By being embedded in the filled mortar r1, the lower end portion s1 having the flat surface t1 exhibits a non-rotating action, and the uppermost stone f1 is prevented from rotating due to vibration during an earthquake. It was configured as follows. When disassembling the tombstone thus assembled, the uppermost stone (meteorite) f1 is pulled upward so that the lower end portion s1 of the connecting rod k1 becomes the concrete portion v1 of the bottomed hole q1. The connecting rod k1 is pulled up leaving the elastic pipe m1.

  When using this seismic device, unlike the former seismic device, the upper end of the connecting rod does not protrude from the upper end surface of the uppermost stone material, so there is an advantage that the problems such as deteriorating the aesthetics of the tombstone can be solved. is there. However, when using such an earthquake-resistant device, a phenomenon occurs in which the uppermost stone f1 moves up and down due to vibration at the time of the earthquake, and the uppermost stone f1 and the stone w1 existing therebelow collide violently. There was a risk of damaging the tombstone. Moreover, since the lower end portion s1 of the connecting rod k1 comes off from the concrete portion v1 of the bottomed hole q1 due to the floating of the uppermost stone material f1, the flat surface t1 of the lower end portion s1 of the connecting rod k1. The anti-rotation action due to s does not work at all, and there is a possibility that the uppermost stone (meteorite) f1 rotates.

Furthermore, because the conventional masonry structure is constructed at the construction site, there is a problem that the construction period of the site construction is prolonged, and there is a case where a cramped work that requires the stone materials to be stacked sequentially in a narrow space is forced. there were.

The present invention has the following excellent effects.
(1) The seismic device according to the present invention employs a structure in which a masonry structure such as a tombstone or a lantern, which is integrated with a connecting rod, is fixed to the foundation using a fixing member. It is possible to reliably prevent the masonry structure from overturning due to vibration during an earthquake.

  (2) Further, as in the earthquake-proof device disclosed in Japanese Patent Laid-Open No. 10-37532, the uppermost stone is not provided with a vertical through hole, but the upper end of the connecting rod is the lower surface of the uppermost stone. Therefore, the nut screwed to the upper end of the connecting rod does not appear on the upper surface of the tombstone. Therefore, since it is not necessary to cover the nut part so as to cover the nut part, the aesthetics of the masonry structure is not impaired, and rainwater enters the nut part and moss grows or is generated in this part.
