また、皿部材28bの底面には切り欠き25が連続するように形成されている。この切り欠き25は、角部目地プレート12の方向に進むに従って端部目地プレート本体26の高さ(厚み)が減少するような傾斜面に形成されている。この切り欠き25は例えば中間の端部目地プレート本体26bの皿部材28bと他方の端部目地プレート本体26cの皿部材28cにのみ形成してもよい。また、皿部材28a、28bの全体に切り欠き25を形成してもよいし、一部に形成してもよい。本実施形態では、中間の端部目地プレート本体26bの底面の中央部付近から他方の端部目地プレート本体26cに向かって切り欠き25が形成されている。 Furthermore, a continuous notch 25 is formed on the bottom surface of the dish member 28b. This notch 25 is formed into an inclined surface such that the height (thickness) of the end joint plate main body 26 decreases as it advances in the direction of the corner joint plate 12. This notch 25 may be formed, for example, only in the dish member 28b of the intermediate end joint plate main body 26b and the dish member 28c of the other end joint plate main body 26c. Moreover, the notch 25 may be formed in the entire plate member 28a, 28b, or may be formed in a part thereof. In this embodiment, a notch 25 is formed from near the center of the bottom surface of the intermediate end joint plate main body 26b toward the other end joint plate main body 26c.

この一方の端部目地プレート本体26aの皿部材28aと中間の端部目地プレート本体26bの皿部材28b及び中間の端部目地プレート本体26bの皿部材28bと他方の端部目地プレート本体26cの皿部材28cは、それぞれ回動軸29を有するヒンジ状の接続部材30で底面側が接続されており、回動軸29は隣り合う皿部材28の当接部付近に位置するように設けられている。この接続部材30としてカバー部材27等を接続するヒンジ部材23を用いてもよい。 The dish member 28a of the one end joint plate body 26a, the dish member 28b of the intermediate end joint plate body 26b, the dish member 28b of the intermediate end joint plate body 26b, and the dish of the other end joint plate body 26c. The members 28c are connected at their bottom sides by hinge-like connecting members 30 each having a rotation shaft 29, and the rotation shaft 29 is provided so as to be located near the contact portion of the adjacent plate members 28. The hinge member 23 that connects the cover member 27 and the like may be used as the connecting member 30.

他方の端部目地プレート本体26cの角部目地プレート12側の側面には、ヒンジ部材23を介してカバー部材27が設けられている。このヒンジ部材23は、他方の端部目地プレート本体26cの底面とカバー部材27の底面を接続するように設けられている。 A cover member 27 is provided on the side surface of the other end joint plate main body 26c on the corner joint plate 12 side via a hinge member 23. This hinge member 23 is provided so as to connect the bottom surface of the other end joint plate main body 26c and the bottom surface of the cover member 27.

このカバー部材27は平面視において矩形状の板材で、本実施形態ではその底面には前記切り欠き25と連続するように傾斜部31が形成されている。切り欠き25及び傾斜部31が形成されている部分の長さとしては、地震による前後方向の揺れ動き幅よりも大きくなるように形成されている。なお、カバー部材27の上面に目地プレート8等と同様の化粧板22を設けてもよい。 The cover member 27 is a rectangular plate member in plan view, and in this embodiment, an inclined portion 31 is formed on the bottom surface thereof so as to be continuous with the notch 25. The length of the portion in which the notch 25 and the inclined portion 31 are formed is set to be larger than the width of the back-and-forth oscillation caused by an earthquake. Note that a decorative board 22 similar to the joint plate 8 or the like may be provided on the upper surface of the cover member 27.

角部目地プレート12は、図6に示すように、本実施形態では浅皿状で端部目地プレート9側の上面に摩擦用の緩やかな傾斜面32が形成された角部目地プレート本体33と、角部目地プレート本体33に充填されたセメントやモルタル等の充填部材21と、充填部材21の上部を覆うように設けられた化粧板22と、角部目地プレート本体33の他端部にヒンジ部材23を介して設けられたカバープレート24とで構成されている。この角部目地プレート12には一端部側に1対の杭ケース20が設けられており、本実施形態では、摺動部材11の係止杭5に係合しているが、端部目地プレート9側の杭ケース20は、第1の目地プレート支持部に設けられた係止杭5に係合するように設けてもよく、このような場合には角部目地プレート12が前後方向にスライド移動できるよう、杭ケース20を長尺とすることが望ましい。また、杭ケース20(特に他方の躯体4の壁面4a側の杭ケース20)は、角部目地プレート12が端部目地プレート9等と上面が略水平になるように、摺動部材11の上面に形成又は固定したゲタ部11aの上に設けることが望ましい。 As shown in FIG. 6, the corner joint plate 12 includes a corner joint plate main body 33 which is shallow dish-shaped and has a gently sloped surface 32 for friction on the upper surface on the side of the end joint plate 9, as shown in FIG. , a filling member 21 such as cement or mortar filled in the corner joint plate main body 33, a decorative board 22 provided to cover the upper part of the filling member 21, and a hinge at the other end of the corner joint plate main body 33. A cover plate 24 is provided via a member 23. A pair of stake cases 20 are provided on one end side of this corner joint plate 12, and in this embodiment, they are engaged with the locking stakes 5 of the sliding member 11, but the end joint plate The pile case 20 on the 9 side may be provided so as to engage with the locking pile 5 provided on the first joint plate support part, and in such a case, the corner joint plate 12 may slide in the front and rear direction. It is desirable that the pile case 20 be long so that it can be moved. Further, the pile case 20 (particularly the pile case 20 on the wall surface 4a side of the other frame 4) is arranged so that the upper surface of the sliding member 11 is such that the upper surface of the corner joint plate 12 is approximately horizontal with the end joint plate 9, etc. It is desirable to provide it on top of the getter portion 11a formed or fixed in the above.

角部目地プレート12の前後方向の寸法は、地震による前後方向の揺れ動き幅の2倍以上になるように形成されており、前記傾斜面32は地震による前後方向の揺れ動き幅よりも大きくなるように形成されている。そのため、切り欠き25や傾斜部31、傾斜面32の角度が非常にゆるくなっている(緩斜面になっている)ため、地震によって傾斜面32の上面を切り欠き25や傾斜部31が乗り上がっても、カバー部材27や端部目地プレート9が大きく跳ね上がることがなく、安全に地震による揺れ動きを吸収することができる。なお、摩擦用(せり上がり用)の緩やかな傾斜面32の傾斜角(例えば角部目地プレート本体33の底面に対する傾斜面32のスベリ摩擦角)は、好ましくは、10度乃至40度、望ましくは11度乃至20度である。 The front-rear dimension of the corner joint plate 12 is formed to be at least twice the width of the back-and-forth sway due to an earthquake, and the inclined surface 32 is formed so as to be larger than the width of the back-and-forth sway due to an earthquake. It is formed. Therefore, the angles of the notch 25, sloped part 31, and sloped surface 32 are very gentle (they are gentle slopes), so the notch 25 and sloped part 31 ride up on the top surface of the sloped surface 32 due to an earthquake. Even in the event of an earthquake, the cover member 27 and the end joint plate 9 do not jump up significantly, and the shaking movement caused by an earthquake can be safely absorbed. The angle of inclination of the gently inclined surface 32 for friction (for rising) (for example, the sliding friction angle of the inclined surface 32 with respect to the bottom surface of the corner joint plate main body 33) is preferably 10 degrees to 40 degrees, preferably It is 11 degrees to 20 degrees.

角部目地プレート12は、本実施形態では、摺動部材11に設けられた1対の係止杭5が角部目地プレート12の1対の杭ケース20に挿入されているが、一端部側の一方の端部が前記第1の目地プレート支持部6に前後方向にスライド移動可能に支持され、一端部の他方の端部(他方の躯体4の壁面4a側の端部)は、摺動部材11に支持されるように設けてもよい。摺動部材11には、係止杭5が設けられており、この係止杭5が角部目地プレート12に設けられた1対の杭ケース20に挿入される。なお、摺動部材11に一端部の全体が支持されるように設けてもよい。角部目地プレート12が前後方向に揺れ動いた場合でも係止杭5と干渉しないように、第1の目地プレート支持部6に設けられた係止杭5が挿入される杭ケース20は、前後方向に長いものを用いることが望ましく、摺動部材11に1対の係止杭5を設けて角部目地プレートを支持する場合には、係止杭5から摺動部材11の端部までの長さを地震による揺れ動き幅より大きくする又は、摺動部材11に係止杭5が入り込める切り欠き等を設けることが望ましい。 In the present embodiment, the corner joint plate 12 has a pair of locking stakes 5 provided on the sliding member 11 inserted into a pair of pile cases 20 of the corner joint plate 12. One end is supported by the first joint plate support part 6 so as to be slidable in the front-rear direction, and the other end of the one end (the end on the wall surface 4a side of the other frame 4) is slidable. It may be provided so as to be supported by the member 11. The sliding member 11 is provided with a locking stake 5, and the locking stake 5 is inserted into a pair of stake cases 20 provided on the corner joint plate 12. Note that it may be provided so that the entire one end portion is supported by the sliding member 11. In order to prevent interference with the locking stake 5 even when the corner joint plate 12 swings in the front-back direction, the pile case 20 into which the locking stake 5 provided on the first joint plate support 6 is inserted is rotated in the front-back direction. It is desirable to use a long one for the sliding member 11, and when a pair of locking stakes 5 are provided on the sliding member 11 to support the corner joint plate, the length from the locking stake 5 to the end of the sliding member 11 is It is desirable to make the width larger than the shaking width due to an earthquake, or to provide a notch or the like in the sliding member 11 into which the locking pile 5 can fit.

通常時(図1の状態)においては、端部目地プレート9の切り欠き25が形成された部位及びカバー部材27は、角部目地プレート12の摩擦用の緩やかな傾斜面32の上面に乗るように、すなわち、切り欠き25と傾斜面32が略当接するように配置される。また、端部目地プレート9と角部目地プレート12の上面が略平坦となるように配置され、目地部2(角部2a及び左右方向の目地部2b)を塞ぐことができる。 Under normal conditions (the state shown in FIG. 1), the portion of the end joint plate 9 in which the notch 25 is formed and the cover member 27 rest on the upper surface of the gently sloped surface 32 for friction of the corner joint plate 12. In other words, the notch 25 and the inclined surface 32 are arranged so as to be substantially in contact with each other. Further, the upper surfaces of the end joint plate 9 and the corner joint plate 12 are arranged so as to be substantially flat, so that the joint portion 2 (the corner portion 2a and the horizontal joint portion 2b) can be closed.

なお、略当接するとは、ぴったりと面接触している状態だけでなく、部分的に接触し、その他の部分は僅かな間隙を有して接近している状態や、僅かな間隙を有して接近している状態も含むものである。
また、本実施形態では、浅皿状の目地プレート本体19等を使用した目地プレート8、端部目地プレート9、角部目地プレート12を用いたが、板状の部材を用いて目地プレート8、端部目地プレート9、角部目地プレート12を形成してもよい。
Note that "approximately in contact" means not only a state where the surfaces are in exact surface contact, but also a state where the parts are in partial contact and the other parts are close to each other with a small gap, or a state where the parts are close to each other with a small gap. This also includes situations in which they are close to each other.
In addition, in this embodiment, the joint plate 8, the end joint plate 9, and the corner joint plate 12 using a shallow dish-shaped joint plate main body 19, etc. are used, but the joint plate 8, End joint plates 9 and corner joint plates 12 may also be formed.

ところで、一方の躯体3の前後方向の目地部2c側の壁面3aと他方の躯体4の壁面4aとの間の縦方向の隙間(前後方向の目地部2cが開口している部位)については壁面用目地装置等(図示せず)を用いて塞ぐことが望ましい。
地震で左右の躯体3、4が左右方向に揺れ動き左右方向の目地部2bが狭くなると、図7に示すように、目地プレート8、端部目地プレート9及び角部目地プレート12の他端部が第2の目地プレート支持部7の乗り上げ傾斜面18により上方にせり上がり地震による揺れ動きを吸収する。
By the way, the vertical gap between the wall surface 3a on the side of the joint 2c in the front-rear direction of one frame 3 and the wall surface 4a of the other frame 4 (the part where the joint 2c in the front-rear direction is open) is the wall surface. It is desirable to close the area using a joint device (not shown).
When the left and right building blocks 3 and 4 sway in the left-right direction due to an earthquake, and the joints 2b in the left-right direction narrow, the other ends of the joint plate 8, end joint plate 9, and corner joint plate 12 become narrower, as shown in FIG. The second joint plate support part 7 rises upward by the rising inclined surface 18 to absorb the shaking motion caused by the earthquake.

地震で躯体3、4が左右方向に揺れ動き左右方向の目地部2bが広くなると、図8に示すように、目地プレート8、端部目地プレート9及び角部目地プレート12の他端部が第2の目地プレート支持部7の上面を左右方向にスライド移動し、地震による揺れ動きを吸収する。 When the frames 3 and 4 sway in the left-right direction due to an earthquake and the joints 2b in the left-right direction widen, the other ends of the joint plates 8, end joint plates 9, and corner joint plates 12 widen as shown in FIG. The upper surface of the joint plate support part 7 is slid in the left and right direction to absorb the shaking movement caused by the earthquake.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが狭くなると、図9に示すように、角部目地プレート12が端部目地プレート9と重なり幅が大きくなるように前後方向にスライド移動して、揺れ動きを吸収する。 When the left and right frames 3 and 4 swing in different front and back directions, and the joint portion 2c in the front and back direction narrows, the corner joint plate 12 overlaps the end joint plate 9 and the width increases. Slide in the direction to absorb the shaking motion.

この時、前述したように切り欠き25や傾斜部31、傾斜面32の角度が緩斜面になっているため、地震によって傾斜面32の上面に端部目地プレート9の切り欠き25やカバー部材27の傾斜部31が乗り上がっても、カバー部材27や端部目地プレート9が大きく跳ね上がることがなく安全に地震による揺れ動きを吸収することができる。 At this time, as mentioned above, since the angles of the notch 25, the inclined part 31, and the inclined surface 32 are gentle slopes, the notch 25 of the end joint plate 9 and the cover member 27 are formed on the upper surface of the inclined surface 32 due to the earthquake. Even if the sloped part 31 of 2 climbs up, the cover member 27 and the end joint plate 9 will not jump up significantly, and the shaking motion due to the earthquake can be safely absorbed.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが広くなると、図10に示すように、端部目地プレート9やカバー部材27が角部目地プレート12の傾斜面32の上面を、その重なり幅が小さくなるように前後方向にスライド移動して、揺れ動きを吸収する。傾斜面32の寸法は地震による揺れ動き幅よりも大きくなるように形成されており、端部目地プレート9とカバー部材27はヒンジ部材23により接続されているため、大きな段差が生じることなく安全に地震による揺れ動きを吸収することができる。 When the left and right bodies 3 and 4 swing in different front and back directions and the joint portion 2c in the front and back direction becomes wider, the end joint plate 9 and the cover member 27 move along the slope 32 of the corner joint plate 12, as shown in FIG. The top surface is slid back and forth so that the overlapping width becomes smaller to absorb the shaking motion. The dimensions of the inclined surface 32 are formed to be larger than the width of shaking caused by an earthquake, and the end joint plate 9 and the cover member 27 are connected by the hinge member 23, so that the earthquake can be safely avoided without creating a large step. It can absorb the shaking movement caused by

[発明を実施するための異なる形態]
次に、図11乃至図15に示す本発明を実施するための異なる形態につき説明する。なお、これらの本発明を実施するための異なる形態の説明に当って、前記本発明を実施するための第1の形態と同一構成部分には同一符号を付して重複する説明を省略する。
[Different forms for carrying out the invention]
Next, different embodiments for implementing the present invention shown in FIGS. 11 to 15 will be explained. In addition, in describing these different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention are given the same reference numerals and redundant explanations will be omitted.

図11乃至図15に示す本発明を実施するための第2の形態において、前記本発明を実施するための第1の形態と主に異なる点は、分割されていない端部目地プレート本体26Aを用い、この端部目地プレート本体26Aの角部目地プレート12側の側面にヒンジ部材23を介して薄板状のカバー部材27Aを設けた端部目地プレート9Aにした点で、このような端部目地プレート9Aを用いた床用目地装置1Aにしても、前記本発明を実施するための第1の形態と同様の作用効果を得ることができる。本実施形態では、端部目地プレート本体26Aは浅皿状に形成されており、この端部目地プレート本体26Aに充填部材21が充填され、その上面に化粧板22が設けられている。 In the second embodiment of the present invention shown in FIGS. 11 to 15, the main difference from the first embodiment of the present invention is that an undivided end joint plate main body 26A is used. This type of end joint plate 9A has a thin plate-like cover member 27A provided on the side surface of the corner joint plate 12 side of the end joint plate main body 26A via a hinge member 23. Even with the floor joint device 1A using the plate 9A, the same effects as in the first embodiment of the present invention can be obtained. In this embodiment, the end joint plate main body 26A is formed in the shape of a shallow dish, the end joint plate main body 26A is filled with a filling member 21, and a decorative board 22 is provided on the upper surface thereof.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが狭くなると、図14に示すように、角部目地プレート12が端部目地プレート9と重なり幅が大きくなるように前後方向にスライド移動して、揺れ動きを吸収する。 When the left and right frames 3 and 4 swing in different front and back directions, and the joint portion 2c in the front and back direction becomes narrower, the corner joint plate 12 overlaps the end joint plate 9 and the width is increased, as shown in FIG. Slide in the direction to absorb the shaking motion.

この時、薄板状のカバー部材27Aを備え、傾斜面32の角度が緩斜面になっているため、地震によって傾斜面32の上面に端部目地プレート9Aの切り欠き25が乗り上がっても、カバー部材27Aや端部目地プレート9Aが大きく跳ね上がることがなく安全に地震による揺れ動きを吸収することができる。 At this time, since the thin plate-shaped cover member 27A is provided and the angle of the slope 32 is a gentle slope, even if the notch 25 of the end joint plate 9A rides on the top surface of the slope 32 due to an earthquake, the cover The member 27A and the end joint plate 9A do not jump up significantly and can safely absorb the shaking motion caused by the earthquake.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが広くなると、図10に示すように、端部目地プレート9Aやカバー部材27Aが角部目地プレート12の傾斜面32の上面を、その重なり幅が小さくなるように前後方向にスライド移動して、揺れ動きを吸収する。傾斜面32の寸法は地震による揺れ動き幅よりも大きくなるように形成されており、端部目地プレート9Aとカバー部材27Aはヒンジ部材23により接続されているため、大きな段差が生じることなく安全に地震による揺れ動きを吸収することができる。 When the left and right bodies 3 and 4 swing in different front and rear directions and the joint portion 2c in the front and back direction becomes wider, the end joint plate 9A and the cover member 27A move along the slope 32 of the corner joint plate 12, as shown in FIG. The top surface is slid back and forth so that the overlapping width becomes smaller to absorb the shaking motion. The dimensions of the inclined surface 32 are formed to be larger than the width of shaking caused by an earthquake, and the end joint plate 9A and the cover member 27A are connected by the hinge member 23, so that the earthquake can be safely avoided without creating a large step. It can absorb the shaking movement caused by

Note that a decorative board 22 similar to the joint plate 8 or the like may be provided on the upper surface of the cover member 27.

角部目地プレート12は、図6に示すように、本実施形態では浅皿状で端部目地プレート9側の上面に摩擦用の緩やかな傾斜面32が形成された角部目地プレート本体33と、角部目地プレート本体33に充填されたセメントやモルタル等の充填部材21と、充填部材21の上部を覆うように設けられた化粧板22と、角部目地プレート本体33の他端部にヒンジ部材23を介して設けられたカバープレート24とで構成されている。この角部目地プレート12には一端部側に1対の杭ケース20が設けられており、本実施形態では、摺動部材11の係止杭5に係合しているが、端部目地プレート9側の杭ケース20は、第1の目地プレート支持部に設けられた係止杭5に係合するように設けてもよく、このような場合には角部目地プレート12が前後方向にスライド移動できるよう、杭ケース20を長尺とすることが望ましい。また、杭ケース20(特に他方の躯体4の壁面4a側の杭ケース20)は、角部目地プレート12が端部目地プレート9等と上面が略水平になるように、摺動部材11の上面に形成又は固定したゲタ部11aの上に設けることが望ましい。 As shown in FIG. 6, the corner joint plate 12 includes a corner joint plate main body 33 which is shallow dish-shaped and has a gently sloped surface 32 for friction on the upper surface on the side of the end joint plate 9, as shown in FIG. , a filling member 21 such as cement or mortar filled in the corner joint plate main body 33, a decorative board 22 provided to cover the upper part of the filling member 21, and a hinge at the other end of the corner joint plate main body 33. A cover plate 24 is provided via a member 23. A pair of stake cases 20 are provided on one end side of this corner joint plate 12, and in this embodiment, they are engaged with the locking stakes 5 of the sliding member 11, but the end joint plate The pile case 20 on the 9 side may be provided so as to engage with the locking pile 5 provided on the first joint plate support part, and in such a case, the corner joint plate 12 may slide in the front and rear direction. It is desirable that the pile case 20 be long so that it can be moved. Further, the pile case 20 (particularly the pile case 20 on the wall surface 4a side of the other frame 4) is arranged so that the upper surface of the sliding member 11 is such that the upper surface of the corner joint plate 12 is approximately horizontal with the end joint plate 9, etc. It is desirable to provide it on top of the getter portion 11a formed or fixed in the above.

角部目地プレート12の前後方向の寸法は、地震による前後方向の揺れ動き幅の2倍以上になるように形成されており、前記傾斜面32は地震による前後方向の揺れ動き幅よりも大きくなるように形成されている。そのため、切り欠き25や傾斜部31、傾斜面32の角度が非常にゆるくなっている(緩斜面になっている)ため、地震によって傾斜面32の上面を切り欠き25や傾斜部31が乗り上がっても、カバー部材27や端部目地プレート9が大きく跳ね上がることがなく、安全に地震による揺れ動きを吸収することができる。なお、摩擦用(せり上がり用)の緩やかな傾斜面32の傾斜角(例えば角部目地プレート本体33の底面に対する傾斜面32のスベリ摩擦角)は、好ましくは、10度乃至40度、望ましくは11度乃至20度である。 The front-rear dimension of the corner joint plate 12 is formed to be at least twice the width of the back-and-forth sway due to an earthquake, and the inclined surface 32 is formed so as to be larger than the width of the back-and-forth sway due to an earthquake. It is formed. Therefore, the angles of the notch 25, sloped part 31, and sloped surface 32 are very gentle (they are gentle slopes), so the notch 25 and sloped part 31 ride up on the top surface of the sloped surface 32 due to an earthquake. Even in the event of an earthquake, the cover member 27 and the end joint plate 9 do not jump up significantly, and the shaking movement caused by an earthquake can be safely absorbed. The angle of inclination of the gently inclined surface 32 for friction (for rising) (for example, the sliding friction angle of the inclined surface 32 with respect to the bottom surface of the corner joint plate main body 33) is preferably 10 degrees to 40 degrees, preferably It is 11 degrees to 20 degrees.

角部目地プレート12は、本実施形態では、摺動部材11に設けられた1対の係止杭5が角部目地プレート12の1対の杭ケース20に挿入されているが、一端部側の一方の端部が前記第1の目地プレート支持部6に前後方向にスライド移動可能に支持され、一端部の他方の端部(他方の躯体4の壁面4a側の端部)は、摺動部材11に支持されるように設けてもよい。摺動部材11には、係止杭5が設けられており、この係止杭5が角部目地プレート12に設けられた1対の杭ケース20に挿入される。なお、摺動部材11に一端部の全体が支持されるように設けてもよい。角部目地プレート12が前後方向に揺れ動いた場合でも係止杭5と干渉しないように、第1の目地プレート支持部6に設けられた係止杭5が挿入される杭ケース20は、前後方向に長いものを用いることが望ましく、摺動部材11に1対の係止杭5を設けて角部目地プレートを支持する場合には、係止杭5から摺動部材11の端部までの長さを地震による揺れ動き幅より大きくする又は、摺動部材11に係止杭5が入り込める切り欠き等を設けることが望ましい。 In the present embodiment, the corner joint plate 12 has a pair of locking stakes 5 provided on the sliding member 11 inserted into a pair of pile cases 20 of the corner joint plate 12. One end is supported by the first joint plate support part 6 so as to be slidable in the front-rear direction, and the other end of the one end (the end on the wall surface 4a side of the other frame 4) is slidable. It may be provided so as to be supported by the member 11. The sliding member 11 is provided with a locking stake 5, and the locking stake 5 is inserted into a pair of stake cases 20 provided on the corner joint plate 12. Note that it may be provided so that the entire one end portion is supported by the sliding member 11. In order to prevent interference with the locking stake 5 even when the corner joint plate 12 swings in the front-back direction, the pile case 20 into which the locking stake 5 provided on the first joint plate support 6 is inserted is rotated in the front-back direction. It is desirable to use a long one for the sliding member 11, and when a pair of locking stakes 5 are provided on the sliding member 11 to support the corner joint plate, the length from the locking stake 5 to the end of the sliding member 11 is It is desirable to make the width larger than the shaking width due to an earthquake, or to provide a notch or the like in the sliding member 11 into which the locking pile 5 can fit.

通常時(図1の状態)においては、端部目地プレート9の切り欠き25が形成された部位及びカバー部材27は、角部目地プレート12の摩擦用の緩やかな傾斜面32の上面に乗るように、すなわち、切り欠き25と傾斜面32が略当接するように配置される。また、端部目地プレート9と角部目地プレート12の上面が略平坦となるように配置され、目地部2(角部2a及び左右方向の目地部2b)を塞ぐことができる。 Under normal conditions (the state shown in FIG. 1), the portion of the end joint plate 9 in which the notch 25 is formed and the cover member 27 rest on the upper surface of the gently sloped surface 32 for friction of the corner joint plate 12. In other words, the notch 25 and the inclined surface 32 are arranged so as to be substantially in contact with each other. Further, the upper surfaces of the end joint plate 9 and the corner joint plate 12 are arranged so as to be substantially flat, so that the joint portion 2 (the corner portion 2a and the horizontal joint portion 2b) can be closed.

なお、略当接するとは、ぴったりと面接触している状態だけでなく、部分的に接触し、その他の部分は僅かな間隙を有して接近している状態や、僅かな間隙を有して接近している状態も含むものである。
また、本実施形態では、浅皿状の目地プレート本体19等を使用した目地プレート8、端部目地プレート9、角部目地プレート12を用いたが、板状の部材を用いて目地プレート8、端部目地プレート9、角部目地プレート12を形成してもよい。
Note that "approximately in contact" means not only a state where the surfaces are in exact surface contact, but also a state where the parts are in partial contact and the other parts are close to each other with a small gap, or a state where the parts are close to each other with a small gap. This also includes situations in which they are close to each other.
In addition, in this embodiment, the joint plate 8, the end joint plate 9, and the corner joint plate 12 using a shallow dish-shaped joint plate main body 19, etc. are used, but the joint plate 8, End joint plates 9 and corner joint plates 12 may also be formed.

ところで、一方の躯体3の前後方向の目地部2c側の壁面3aと他方の躯体4の壁面4aとの間の縦方向の隙間(前後方向の目地部2cが開口している部位)については壁面用目地装置等(図示せず)を用いて塞ぐことが望ましい。
地震で左右の躯体3、4が左右方向に揺れ動き左右方向の目地部2bが狭くなると、図7に示すように、目地プレート8、端部目地プレート9及び角部目地プレート12の他端部が第2の目地プレート支持部7の乗り上げ傾斜面18により上方にせり上がり地震による揺れ動きを吸収する。
By the way, the vertical gap between the wall surface 3a on the side of the joint 2c in the front-rear direction of one frame 3 and the wall surface 4a of the other frame 4 (the part where the joint 2c in the front-rear direction is open) is the wall surface. It is desirable to close the area using a joint device (not shown).
When the left and right building blocks 3 and 4 sway in the left-right direction due to an earthquake, and the joints 2b in the left-right direction narrow, the other ends of the joint plate 8, end joint plate 9, and corner joint plate 12 become narrower, as shown in FIG. The second joint plate support part 7 rises upward by the rising inclined surface 18 to absorb the shaking motion caused by the earthquake.

地震で躯体3、4が左右方向に揺れ動き左右方向の目地部2bが広くなると、図8に示すように、目地プレート8、端部目地プレート9及び角部目地プレート12の他端部が第2の目地プレート支持部7の上面を左右方向にスライド移動し、地震による揺れ動きを吸収する。 When the frames 3 and 4 sway in the left-right direction due to an earthquake and the joints 2b in the left-right direction widen, the other ends of the joint plates 8, end joint plates 9, and corner joint plates 12 widen as shown in FIG. The upper surface of the joint plate support part 7 is slid in the left and right direction to absorb the shaking movement caused by the earthquake.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが狭くなると、図9に示すように、角部目地プレート12が端部目地プレート9と重なり幅が大きくなるように前後方向にスライド移動して、揺れ動きを吸収する。 When the left and right frames 3 and 4 swing in different front and back directions, and the joint portion 2c in the front and back direction narrows, the corner joint plate 12 overlaps the end joint plate 9 and the width increases. Slide in the direction to absorb the shaking motion.

この時、前述したように切り欠き25や傾斜部31、傾斜面32の角度が緩斜面になっているため、地震によって傾斜面32の上面に端部目地プレート9の切り欠き25やカバー部材27の傾斜部31が乗り上がっても、カバー部材27や端部目地プレート9が大きく跳ね上がることがなく安全に地震による揺れ動きを吸収することができる。 At this time, as mentioned above, since the angles of the notch 25, the inclined part 31, and the inclined surface 32 are gentle slopes, the notch 25 of the end joint plate 9 and the cover member 27 are formed on the upper surface of the inclined surface 32 due to the earthquake. Even if the sloped part 31 of 2 climbs up, the cover member 27 and the end joint plate 9 will not jump up significantly, and the shaking motion due to the earthquake can be safely absorbed.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが広くなると、図10に示すように、端部目地プレート9やカバー部材27が角部目地プレート12の傾斜面32の上面を、その重なり幅が小さくなるように前後方向にスライド移動して、揺れ動きを吸収する。傾斜面32の寸法は地震による揺れ動き幅よりも大きくなるように形成されており、端部目地プレート9とカバー部材27はヒンジ部材23により接続されているため、大きな段差が生じることなく安全に地震による揺れ動きを吸収することができる。 When the left and right bodies 3 and 4 swing in different front and back directions and the joint portion 2c in the front and back direction becomes wider, the end joint plate 9 and the cover member 27 move along the slope 32 of the corner joint plate 12, as shown in FIG. The top surface is slid back and forth so that the overlapping width becomes smaller to absorb the shaking motion. The dimensions of the inclined surface 32 are formed to be larger than the width of shaking caused by an earthquake, and the end joint plate 9 and the cover member 27 are connected by the hinge member 23, so that the earthquake can be safely avoided without creating a large step. It can absorb the shaking movement caused by

[発明を実施するための異なる形態]
次に、図11乃至図15に示す本発明を実施するための異なる形態につき説明する。なお、これらの本発明を実施するための異なる形態の説明に当って、前記本発明を実施するための第1の形態と同一構成部分には同一符号を付して重複する説明を省略する。
[Different forms for carrying out the invention]
Next, different embodiments for implementing the present invention shown in FIGS. 11 to 15 will be explained. In addition, in describing these different embodiments for carrying out the present invention, the same components as those in the first embodiment for carrying out the present invention are given the same reference numerals and redundant explanations will be omitted.

図11乃至図15に示す本発明を実施するための第2の形態において、前記本発明を実施するための第1の形態と主に異なる点は、分割されていない端部目地プレート本体26Aを用い、この端部目地プレート本体26Aの角部目地プレート12側の側面にヒンジ部材23を介して薄板状のカバー部材27Aを設けた端部目地プレート9Aにした点で、このような端部目地プレート9Aを用いた床用目地装置1Aにしても、前記本発明を実施するための第1の形態と同様の作用効果を得ることができる。本実施形態では、端部目地プレート本体26Aは浅皿状に形成されており、この端部目地プレート本体26Aに充填部材21が充填され、その上面に化粧板22が設けられている。 In the second embodiment of the present invention shown in FIGS. 11 to 15, the main difference from the first embodiment of the present invention is that an undivided end joint plate main body 26A is used. This type of end joint plate 9A has a thin plate-like cover member 27A provided on the side surface of the corner joint plate 12 side of the end joint plate main body 26A via a hinge member 23. Even with the floor joint device 1A using the plate 9A, the same effects as in the first embodiment of the present invention can be obtained. In this embodiment, the end joint plate main body 26A is formed in the shape of a shallow dish, the end joint plate main body 26A is filled with a filling member 21, and a decorative board 22 is provided on the upper surface thereof.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが狭くなると、図14に示すように、角部目地プレート12が端部目地プレート9と重なり幅が大きくなるように前後方向にスライド移動して、揺れ動きを吸収する。 When the left and right frames 3 and 4 swing in different front and back directions, and the joint portion 2c in the front and back direction becomes narrower, the corner joint plate 12 overlaps the end joint plate 9 and the width is increased, as shown in FIG. Slide in the direction to absorb the shaking motion.

この時、薄板状のカバー部材27Aを備え、傾斜面32の角度が緩斜面になっているため、地震によって傾斜面32の上面に端部目地プレート9Aの切り欠き25が乗り上がっても、カバー部材27Aや端部目地プレート9Aが大きく跳ね上がることがなく安全に地震による揺れ動きを吸収することができる。 At this time, since the thin plate-shaped cover member 27A is provided and the angle of the slope 32 is a gentle slope, even if the notch 25 of the end joint plate 9A rides on the top surface of the slope 32 due to an earthquake, the cover The member 27A and the end joint plate 9A do not jump up significantly and can safely absorb the shaking motion caused by the earthquake.

左右の躯体3、4が異なる前後方向に揺れ動き、前後方向の目地部2cが広くなると、図10に示すように、端部目地プレート9Aやカバー部材27Aが角部目地プレート12の傾斜面32の上面を、その重なり幅が小さくなるように前後方向にスライド移動して、揺れ動きを吸収する。傾斜面32の寸法は地震による揺れ動き幅よりも大きくなるように形成されており、端部目地プレート9Aとカバー部材27Aはヒンジ部材23により接続されているため、大きな段差が生じることなく安全に地震による揺れ動きを吸収することができる。 When the left and right bodies 3 and 4 swing in different front and rear directions and the joint portion 2c in the front and back direction becomes wider, the end joint plate 9A and the cover member 27A move along the slope 32 of the corner joint plate 12, as shown in FIG. The top surface is slid back and forth so that the overlapping width becomes smaller to absorb the shaking motion. The dimensions of the inclined surface 32 are formed to be larger than the width of shaking caused by an earthquake, and the end joint plate 9A and the cover member 27A are connected by the hinge member 23, so that the earthquake can be safely avoided without creating a large step. It can absorb the shaking movement caused by
