Description

本発明は免震装置を有する躯体の間の目地部を塞ぐ目地カバー装置に関する。 The present invention relates to a joint cover device that closes a joint portion between a skeleton having a seismic isolation device.

従来、アイソレーター（免震装置）を有した免震建物の一方の躯体と他方の躯体間の目地部を塞ぐ目地カバー装置としては、例えば、「建物の下部外壁躯体に目地部を介して設けられた床躯体の目地部側の上面と隙間を介して先端部が位置する、該目地部を覆うように設けられた庇と、この庇の底面に所定間隔で固定された複数個のレールに前記隙間より床躯体上へ突出するようにスライド移動可能に取付けられた先端部に下方へ突出するストッパー板を備える複数個のステップ板と、この複数個のステップ板を常時収納方向に付勢する付勢機構と、前記床躯体の目地部側端部に前記ストッパー板と前後方向に建物本体が揺れ動いても係合して、ステップ板を引き出すことができる係合片とからなることを特徴とする目地カバー装置」が知られている（特許文献１）。 Conventionally, as a joint cover device for closing a joint portion between one skeleton and the other skeleton of a seismic isolation building having an isolator (seismic isolation device), for example, "provided on the lower outer wall skeleton of the building via a joint portion". The eaves are provided so as to cover the joints where the tip is located through a gap with the upper surface of the floor skeleton on the joint side, and a plurality of rails fixed to the bottom surface of the eaves at predetermined intervals. A plurality of step plates having a stopper plate protruding downward at the tip portion attached so as to slide and move so as to project from the gap onto the floor skeleton, and the plurality of step plates are always urged in the storage direction. It is characterized by comprising a force mechanism and an engaging piece capable of pulling out a step plate by engaging with the stopper plate at the joint end side end of the floor frame even if the building body swings in the front-rear direction. A "joint cover device" is known (Patent Document 1).

しかしながら、このような目地カバー装置では、直線的な目地部であれば地震が発生した場合にも目地部が開口しないように塞ぐことができ、かつ、躯体等が破損しないように地震に追従して揺れ動きを吸収することが可能であるが、角部を有する目地部に用いられた場合、地震によって目地部が広くなるように揺れ動いた際に、目地部の角部を塞ぐことができず、人や物が目地部の下方に落下してしまうおそれがあった。 However, with such a joint cover device, if the joint is a straight joint, it can be closed so that the joint does not open even when an earthquake occurs, and the joint follows the earthquake so that the skeleton and the like are not damaged. However, when it is used for joints with corners, it cannot close the corners of the joints when it shakes so that the joints become wider due to an earthquake. There was a risk that people or objects would fall below the joints.

なお付言すると、ワイヤー１６は第１の目地プレート９の出入方向から、一旦滑車１７で方向転換する。その滑車１７から第１の目地プレート９の移動寸法分以上を隔てた所に、ワイヤー１６の留め具を付けて、それから先は付勢具１８（引きバネ）を用いて他方の躯体４側へ付勢している。 As an additional note, the wire 16 is once changed in direction by the pulley 17 from the direction of entry and exit of the first joint plate 9. Attach the fastener of the wire 16 at a place separated from the pulley 17 by the moving dimension of the first joint plate 9 or more, and then use the urging tool 18 (pulling spring) to move to the other skeleton 4 side. I'm urging.

係合部１０ は、本実施形態では、一方の躯体３の目地部２側の壁面に設けられており、一方の躯体３の床面よりもその上端部が上方へ突出しており、この突出した部位が前記被係合部８に係合し、目地部２が広くなった場合に第１の目地プレート９を一方の躯体側へ突出させる。この係合部１０は、金属等のプレートで、一方の躯体３の壁面にビス（図示せず）等により固定されているが、一方の躯体３に一体的に形成してもよい。 In the present embodiment, the engaging portion 10 is provided on the wall surface of one skeleton 3 on the joint portion 2 side, and the upper end portion thereof protrudes upward from the floor surface of the one skeleton 3, and the protruding portion 10 protrudes. When the portion engages with the engaged portion 8 and the joint portion 2 becomes wider, the first joint plate 9 is projected toward one of the skeletons. The engaging portion 10 is a plate made of metal or the like and is fixed to the wall surface of one of the skeletons 3 with screws (not shown) or the like, but may be integrally formed with the one skeleton 3.

第２のレール部材１２は、第１のレール部材７と同様の形状となっており、本実施形態では、前後方向の目地部２ｂと略平行となるように１対設けられている。この第２のレール部材１２は、上方の平坦面が複数個の第１の目地プレート９の底面を連結するように取り付けられている。 The second rail member 12 has the same shape as the first rail member 7, and in the present embodiment, a pair is provided so as to be substantially parallel to the joint portion 2b in the front-rear direction. The second rail member 12 is attached so that the upper flat surface connects the bottom surfaces of the plurality of first joint plates 9.

第２の目地プレート１３は、前記第１の目地プレートと略同様の構成となっており、この第２の目地プレート１３についても、地震によって左右の躯体３、４が揺れ動き、その揺れ動きが終了した際に、自動的に通常時の状態に復帰する復帰手段１９を有している。本実施形態では、第１の目地プレート９と同様に、目地部２の角部２ａと反対方向へ付勢する付勢手段が復帰手段１９として設けられている。例えば、図４に示すように、この第２の目地プレート１３に用いられる復帰手段１９は、第２の目地プレート１３の後端部付近に一端部が取り付けられたワイヤー１６と、このワイヤー１６の他端部に取り付けられ、第２の目地プレート１３を目地部２の角部２ａ側の反対方向へ付勢するとともに、第２の目地プレート１３の後端部から離間した部位の第１の目地プレート９に取り付けられた付勢具１８で構成されている。 The second joint plate 13 has substantially the same configuration as the first joint plate, and the left and right skeletons 3 and 4 of the second joint plate 13 also sway due to the earthquake, and the swaying movement is completed. At that time, it has a return means 19 that automatically returns to the normal state. In the present embodiment, similarly to the first joint plate 9, an urging means for urging the joint portion 2 in the direction opposite to the corner portion 2a is provided as the returning means 19. For example, as shown in FIG. 4, the returning means 19 used for the second joint plate 13 includes a wire 16 having one end attached to the vicinity of the rear end of the second joint plate 13 and the wire 16. Attached to the other end, the second joint plate 13 is urged in the opposite direction to the corner 2a side of the joint portion 2, and the first joint at a portion separated from the rear end portion of the second joint plate 13. It is composed of an urging tool 18 attached to the plate 9.

なお、第２の目地プレート１３の被係合部８が係合する係合部１０も一方の躯体３の目地部２の角部２ａ付近の壁面に設けられている。 The engaging portion 10 with which the engaged portion 8 of the second joint plate 13 engages is also provided on the wall surface near the corner portion 2a of the joint portion 2 of one of the skeletons 3.

ところで、本実施形態では、第２の目地プレート１３を付勢する付勢手段を復帰手段１９として用いたが、第２の目地プレート１３の幅方向（第２のレール部材１２と直交する方向）にスライド移動できるように、一方の躯体３に第２の目地プレート１３の突出端部を取り付けて復帰手段１９としてもよい。このように取り付けることにより、地震によって目地部２の幅が変化しても、破損することなく揺れ動きに追従することができ、地震による揺れ動きが終了した際には、自動的に通常時の状態に復帰する。 By the way, in the present embodiment, the urging means for urging the second joint plate 13 is used as the returning means 19, but the width direction of the second joint plate 13 (direction orthogonal to the second rail member 12). The protruding end portion of the second joint plate 13 may be attached to one of the skeletons 3 so that the joint plate 13 can be slid and moved. By attaching in this way, even if the width of the joint portion 2 changes due to an earthquake, it can follow the swaying motion without being damaged, and when the swaying motion due to the earthquake ends, it automatically returns to the normal state. Return.

第２の目地プレート１３は、その幅が前記第１の目地プレート９の長さ方向の寸法（前後方向の目地部２ｂにおいては、左右方向、左右方向の目地部２ｃにおいては、前後方向、）と略同寸法又はわずかに小さい程度（目地部２を略覆える程度）の寸法に形成されており、通常時において互いに上下方向に間隙を隔てて重なった状態で目地部２の角部２ａを覆っている。通常時においては、この上部に第１の目地プレート９及び閉塞部６も位置する。 The width of the second joint plate 13 is the dimension in the length direction of the first joint plate 9 (the joint portion 2b in the front-rear direction is in the left-right direction, and the joint portion 2c in the left-right direction is in the front-rear direction).
