A support recess, a rear end supported by the joint plate support recess, a tip supported by the joint plate slide support recess, and a bottom surface excluding both ends that cover the joint are the joint parts of the joint plate slide support recess. A plurality of joint plates arranged in parallel are formed with recesses that can prevent contact with the side edges, and the rear end of each of the plurality of joint plates is connected to the tip end of the plurality of joint plates. The joint plate is capable of rotating in the vertical direction and is attached so that it can be moved in the same direction as the other floor structure when the left and right floor structures shake in different front and rear directions due to an earthquake. A floor joint device with a characteristic sloped joint section is known (Patent Document 1).

このような床用目地装置では、目地プレートを係止杭で一方の躯体に係止しているが、通常係止杭と杭ボックスとの間には前後方向にわずかに隙間を有するものであった。そのため、床面の傾斜によって目地プレートがずり落ちてしまい、目地部が開口するおそれがあった。 In this type of floor joint device, the joint plate is locked to one of the building blocks using locking stakes, but there is usually a slight gap in the front and back direction between the locking stake and the stake box. Ta. Therefore, there was a risk that the joint plate would slide down due to the slope of the floor surface, causing the joint portion to open.

他方の躯体４には、目地プレート１０の他端部が左右方向にスライド移動可能な凹所状の第２の目地プレート支持部８が形成されている。この第２の目地プレート支持部８の目地部２と反対側の端部には、地震によって目地部２が狭くなった場合に、目地プレート１０の他端部が乗り上げる乗り上げ傾斜面７が形成されている。 The other frame 4 is formed with a recessed second joint plate support portion 8 in which the other end of the joint plate 10 is slidable in the left-right direction. At the end of the second joint plate support part 8 opposite to the joint part 2, a running slope 7 is formed on which the other end of the joint plate 10 rides when the joint part 2 becomes narrow due to an earthquake. ing.

目地プレート１０は、図５に示すように、浅皿状の目地プレート本体１３と、前記目地プレート本体１３の一端部側に設けられ、前記係止杭５が挿入される１対の杭ケース９と、前記目地プレート本体１３に充填されたセメントやモルタル等の充填部材１４と、前記杭ケース９の上部及び充填部材１４の上部を覆うように設けられた化粧板１５と、目地プレート本体１３の他端部にヒンジ部材１６を介して設けられたカバープレート１７と、目地プレート本体の一端部側の底部に形成された被係合部１８とで構成されている。 As shown in FIG. 5, the joint plate 10 includes a shallow dish-shaped joint plate main body 13, and a pair of pile cases 9 provided at one end side of the joint plate main body 13, into which the locking stakes 5 are inserted. , a filling member 14 such as cement or mortar filled in the joint plate main body 13 , a decorative board 15 provided so as to cover the upper part of the pile case 9 and the upper part of the filling member 14 , and the joint plate main body 13 . It is comprised of a cover plate 17 provided at the other end via a hinge member 16, and an engaged portion 18 formed at the bottom of one end of the joint plate main body.

被係合部１８は、目地プレート本体１３の一端部側の略中央部の底部に形成されており、位置決め手段１１を構成している。すなわち、本実施形態では、図６に示すように、位置決め手段１１は、目地プレート１０の一端部側の底面に形成された凹所状の被係合部１８と、一方の躯体に設けられ、前記被係合部１８に係合する突起状の係合片１２とで構成されている。 The engaged portion 18 is formed at the bottom of the joint plate main body 13 at a substantially central portion on one end side, and constitutes the positioning means 11 . That is, in this embodiment, as shown in FIG. 6, the positioning means 11 is provided in the recess-shaped engaged portion 18 formed on the bottom surface of one end side of the joint plate 10, and on one of the building blocks, It is comprised of a protruding engagement piece 12 that engages with the engaged portion 18 .

この位置決め手段１１は、目地プレート１０が前後方向に移動しないように拘束するように形成されており、被係合部１８の前後方向の壁面に係合片１２の前後方向の側面が線接触又は面接触するように形成されている。なお、被係合部１８の前後方向の内壁面の両側面に係合片１２の前後方向の側面が当接してもよいが、少なくとも勾配の高い方の内壁面と係合片１２の前後方向の側面が線接触又は面接触するように形成すればどのような形状に形成してもよい。 This positioning means 11 is formed to restrain the joint plate 10 from moving in the front-rear direction, and the front-rear side surface of the engaging piece 12 is in line contact with the front-rear wall surface of the engaged portion 18 or It is formed so that it makes surface contact. Note that the front and rear side surfaces of the engagement piece 12 may come into contact with both sides of the inner wall surface of the engaged portion 18 in the front and rear direction, but at least the inner wall surface of the engagement piece 12 that has a higher slope in the front and rear direction It may be formed into any shape as long as the side surfaces thereof are in line contact or surface contact.

本実施形態では、被係合部１８は平面視において略四角形状に形成され、側面視においては勾配の高い方の上部の角が鋭角となるような略四角形状に形成され、係合片１２もこの被係合部に対応するように平面視略四角形状で、側面視においては上部が鋭角となるような形状に形成されている。 In the present embodiment, the engaged portion 18 is formed in a substantially square shape in a plan view, and in a side view, in a substantially square shape such that the upper corner of the higher slope is an acute angle. In order to correspond to the engaged portion, the upper portion has a substantially rectangular shape when viewed from above, and the upper portion thereof is formed at an acute angle when viewed from the side.

ところで、位置決め手段１１は目地プレート１０の前後方向の移動を阻害するように形成されるが、目地プレート１０の他端部が上方へ回動する場合には、その動きを阻害しないような形状とすることが望ましい。このため、少なくとも係合片の他方の躯体４側の側面には、好ましくは一方の躯体３側へ傾斜する傾斜面状に形成することが望ましい。 By the way, the positioning means 11 is formed so as to obstruct the movement of the joint plate 10 in the front-rear direction, but when the other end of the joint plate 10 rotates upward, the positioning means 11 is formed in a shape that does not obstruct the movement. It is desirable to do so. For this reason, it is desirable that at least the side surface of the engagement piece on the other frame 4 side is formed into an inclined surface shape that is preferably inclined toward the one frame 3 side.

地震で左右の躯体３、４が左右方向に揺れ動き目地部２が狭くなると、図７に示すように、目地プレート１０の他端部が第２の目地プレート支持部８の乗り上げ傾斜面７により目地プレート１０の一端部側の上端部付近を支点に上方にせり上がり地震による揺れ動きを吸収する。 When the left and right building blocks 3 and 4 sway in the left-right direction due to an earthquake and the joint portion 2 narrows, the other end of the joint plate 10 runs over the second joint plate support portion 8 and the inclined surface 7 closes the joint, as shown in FIG. The plate 10 rises upward using the upper end of the plate 10 as a fulcrum 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目地部２が広くなると、図８に示すように、目地プレート１０の他端部が第２の目地プレート支持部８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 building blocks 3 and 4 sway in the left-right direction due to an earthquake and the joint portion 2 widens, the other end of the joint plate 10 slides on the upper surface of the second joint plate support portion 8 in the left-right direction, as shown in FIG. , absorbs the shaking motion caused by earthquakes.

図示しないが地震によって左右の躯体３、４が異なる前後方向に揺れ動くと、目地プレート１０は一方の躯体３に追従するように動き、地震による揺れ動きを吸収する。このとき、位置決め手段１１に地震による荷重が加わるため、目地プレート１０の杭ケース９や係止杭５に荷重が加わることを防止でき、これらの部品が破損等することを防止できる。 Although not shown, when the left and right building blocks 3 and 4 shake in different front and back directions due to an earthquake, the joint plate 10 moves to follow one of the building blocks 3 and absorbs the shaking movement caused by the earthquake. At this time, since the load due to the earthquake is applied to the positioning means 11, it is possible to prevent the load from being applied to the pile case 9 and the locking pile 5 of the joint plate 10, and it is possible to prevent these parts from being damaged.

［発明を実施するための異なる形態］
次に、図９乃至図１２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. 9 to 12 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９乃至図１２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、杭ケース９の前後方向の側面に突出して略当接する当接部１９を設けた係止杭５Ａと、前記杭ケース９とで位置決め手段１１Ａを構成した点で、このような位置決め手段１１Ａを備える床用目地装置１Ａにしても、前記本発明を実施するための第１の形態と同様な作用効果が得られる。ところで、本実施形態では、被係合部１８を有さない目地プレート１０Ａが用いられている。 In the second embodiment of the present invention shown in FIGS. 9 to 12, the main difference from the first embodiment of the present invention is that the pile case 9 has an approximately In that the positioning means 11A is constituted by the locking pile 5A provided with the abutting part 19 and the pile case 9, the floor joint device 1A including such a positioning means 11A can also be adapted to the present invention. The same effects as in the first embodiment can be obtained. By the way, in this embodiment, the joint plate 10A that does not have the engaged portion 18 is used.

この当接部１９は、本実施形態では、係止杭５Ａの上端部付近に突出するように設けられており、勾配が高い方の杭ケース９の前後方向の側面に略当接する。略当接するとは、接触している状態だけでなく、僅かな間隙を有して接近している状態も含まれる。位置決め手段１１Ａとしては当接部１９が接触することが望ましいが、僅かな間隙を有しているだけであれば、目地部２が開口するほど目地プレート１０Ａが前後方向に移動することは防止でき、発明の課題を解決することができる。 In this embodiment, this contact portion 19 is provided so as to protrude near the upper end of the locking pile 5A, and substantially contacts the side surface in the front-rear direction of the pile case 9 with a higher slope. "Substantially in contact" includes not only a state in which they are in contact, but also a state in which they are close to each other with a slight gap. It is desirable that the abutting portion 19 contacts the positioning means 11A, but if there is only a small gap, it is possible to prevent the joint plate 10A from moving in the front-rear direction to the extent that the joint portion 2 opens. , the problem of the invention can be solved.

本実施形態では、当接部１９を係止杭５Ａの上端部付近のみに形成しているが、例えば、目地プレート１０Ａの回動を阻害しない程度に当接部１９の寸法を大きくしてもよい。また、すべての係止杭５Ａに当接部１９を形成しているが、目地プレート１０の１対の杭ケース９のうちいずれか一方のみに当接部１９が当接するように形成してもよい。この当接部１９は、係止杭５Ａと一体的に形成してもよく、係止杭５Ａに目地プレート１０Ａを係止した後、溶接、ボルトやビスで固定してもよい。 In this embodiment, the contact portion 19 is formed only near the upper end of the locking pile 5A, but for example, the size of the contact portion 19 may be increased to the extent that rotation of the joint plate 10A is not inhibited. good. Further, although the contact portions 19 are formed on all of the locking piles 5A, the contact portions 19 may be formed so as to contact only one of the pair of pile cases 9 of the joint plate 10. good. This contact portion 19 may be formed integrally with the locking pile 5A, or may be fixed by welding, bolts, or screws after the joint plate 10A is locked to the locking pile 5A.

係止杭５Ａにボルトやビスにより当接部１９を固定する場合には、杭ケース９の寸法に誤差が生じている場合や、杭ケースの仕様がことなっても内壁面に確実に当接できるよう、様々な寸法の当接部１９を準備しておき、適切な厚さ（寸法）の当接部１９を固定することにより、より効果的に目地プレート１０Ａの前後方向への移動を防止することができる。 When fixing the contact part 19 to the locking pile 5A with bolts or screws, it is possible to ensure that it contacts the inner wall surface even if there is an error in the dimensions of the pile case 9 or the specifications of the pile case are different. By preparing abutting portions 19 of various dimensions and fixing the abutting portions 19 of appropriate thickness (dimensions), the movement of the joint plate 10A in the front-rear direction can be more effectively prevented. can do.

なお、本発明の実施形態では、係合片と被係合部を用いるものや、係止杭に当接部を設けた位置決め手段について説明したが、例えば一方の躯体に目地プレートの前後方向の側面が嵌合するような枠状の目地プレート設置部等を形成して位置決め手段としてもよいし、その他目地プレートの他端部が回動でき、かつ、目地プレートが一方の躯体に対して前後方向に移動しないような位置決め手段を用いることができる。 In addition, in the embodiments of the present invention, the positioning means using an engaging piece and an engaged part and a positioning means in which a contact part is provided on a locking pile have been described, but for example, a positioning means using a joint plate in the front and rear direction on one of the building blocks is explained. It may be used as a positioning means by forming a frame-shaped joint plate installation part that the sides fit into, or the other end of the joint plate can be rotated, and the joint plate can be moved back and forth relative to one of the building blocks. A positioning means that does not move in the direction can be used.

また、杭ケースの底部は開口しているが、この開口の前後方向の寸法を係止杭の前後方向の側面と略当接するような寸法とすることにより、係止杭と杭ケースにも位置決め手段の機能を持たせることができる。目地プレートが軽量であり、係止杭に大きな荷重がかからない場合には、このような杭ケースと係止杭のみで位置決め手段を構成しても良い。さらに、第１又は第２実施形態の位置決め手段とこのような杭ケースと係止杭を用いた位置決め手段を併用してもよい。 In addition, although the bottom of the pile case is open, by making the dimensions of this opening in the front-rear direction so that it almost touches the front-back side of the locking pile, the locking pile and the pile case can also be positioned. It can have the function of a means. If the joint plate is lightweight and a large load is not applied to the locking pile, the positioning means may be constituted by only such a pile case and the locking pile. Furthermore, the positioning means of the first or second embodiment and the positioning means using such a stake case and a locking stake may be used together.

本発明は目地部を介して設けられた躯体の間の目地部を塞ぐ床用目地装置に関する。 The present invention relates to a floor joint device that closes joints between building blocks provided through joints.

従来、前後方向に勾配を有する床面間の目地部を塞ぐ床用目地装置としては、例えば「前後方向に勾配のある目地部を介して設けられた左右の床躯体の一方の目地部側の床躯体に形成された、反目地部側が傾斜面の目地プレートスライド支持凹部と、この目地プレートスライド支持凹部と対向する前記左右の床躯体の他方の目地部側の床躯体に形成された目地プレート支持凹部と、この目地プレート支持凹部に後端部が支持され、先端部が前記目地プレートスライド支持凹部に支持されて目地部を覆う両端部を除く底面が、該目地プレートスライド支持凹部の目地部側端部と接触するのを防止できる凹部が形成された、並列配置された複数個の目地プレートと、この複数個の目地プレートのそれぞれの後端部を、該複数個の目地プレートの先端部の上下方向の回動が可能で、かつ地震で前記左右の床躯体が異なる前後方向に揺れ動いた場合に、他方の床躯体と同方向に移動できるように取付ける目地プレート取付具とからなることを特徴とする勾配のある目地部の床用目地装置」が知られている（特許文献１）。 Conventionally, floor joint devices that close joints between floor surfaces that slope in the front-rear direction have been used for A joint plate slide support recess formed in the floor structure and having an inclined surface on the side opposite to the joint, and a joint plate formed in the floor structure on the other joint side of the left and right floor structures facing the joint plate slide support recess. A support recess, a rear end supported by the joint plate support recess, a tip supported by the joint plate slide support recess, and a bottom surface excluding both ends that cover the joint are the joint parts of the joint plate slide support recess. A plurality of joint plates arranged in parallel are formed with recesses that can prevent contact with the side edges, and the rear end of each of the plurality of joint plates is connected to the tip end of the plurality of joint plates. The joint plate is capable of rotating in the vertical direction and is attached so that it can be moved in the same direction as the other floor structure when the left and right floor structures shake in different front and rear directions due to an earthquake. A floor joint device with a characteristic sloped joint section is known (Patent Document 1).

このような床用目地装置では、目地プレートを係止杭で一方の躯体に係止しているが、通常係止杭と杭ボックスとの間には前後方向にわずかに隙間を有するものであった。そのため、床面の傾斜によって目地プレートがずり落ちてしまい、目地部が開口するおそれがあった。 In this type of floor joint device, the joint plate is locked to one of the building blocks using locking stakes, but there is usually a slight gap in the front and back direction between the locking stake and the stake box. Ta. Therefore, there was a risk that the joint plate would slide down due to the slope of the floor surface, causing the joint portion to open.

This engagement piece 12 is also welded to a metal plate (not shown) or the like provided on the first joint plate support portion 6 with screws or the like. In this embodiment, the engaging piece 12 is provided on the first joint plate support portion 6, but it may also be provided, for example, on the wall surface on the joint portion 2 side of one frame 3.

他方の躯体４には、目地プレート１０の他端部が左右方向にスライド移動可能な凹所状の第２の目地プレート支持部８が形成されている。この第２の目地プレート支持部８の目地部２と反対側の端部には、地震によって目地部２が狭くなった場合に、目地プレート１０の他端部が乗り上げる乗り上げ傾斜面７が形成されている。 The other frame 4 is formed with a recessed second joint plate support portion 8 in which the other end of the joint plate 10 is slidable in the left-right direction. At the end of the second joint plate support part 8 opposite to the joint part 2, a running slope 7 is formed on which the other end of the joint plate 10 rides when the joint part 2 becomes narrow due to an earthquake. ing.

目地プレート１０は、図５に示すように、浅皿状の目地プレート本体１３と、前記目地プレート本体１３の一端部側に設けられ、前記係止杭５が挿入される１対の杭ケース９と、前記目地プレート本体１３に充填されたセメントやモルタル等の充填部材１４と、前記杭ケース９の上部及び充填部材１４の上部を覆うように設けられた化粧板１５と、目地プレート本体１３の他端部にヒンジ部材１６を介して設けられたカバープレート１７と、目地プレート本体の一端部側の底部に形成された被係合部１８とで構成されている。 As shown in FIG. 5, the joint plate 10 includes a shallow dish-shaped joint plate main body 13, and a pair of pile cases 9 provided at one end side of the joint plate main body 13, into which the locking stakes 5 are inserted. , a filling member 14 such as cement or mortar filled in the joint plate main body 13 , a decorative board 15 provided so as to cover the upper part of the pile case 9 and the upper part of the filling member 14 , and the joint plate main body 13 . It is comprised of a cover plate 17 provided at the other end via a hinge member 16, and an engaged portion 18 formed at the bottom of one end of the joint plate main body.

被係合部１８は、目地プレート本体１３の一端部側の略中央部の底部に形成されており、位置決め手段１１を構成している。すなわち、本実施形態では、図６に示すように、位置決め手段１１は、目地プレート１０の一端部側の底面に形成された凹所状の被係合部１８と、一方の躯体に設けられ、前記被係合部１８に係合する突起状の係合片１２とで構成されている。 The engaged portion 18 is formed at the bottom of the joint plate main body 13 at a substantially central portion on one end side, and constitutes the positioning means 11 . That is, in this embodiment, as shown in FIG. 6, the positioning means 11 is provided in the recess-shaped engaged portion 18 formed on the bottom surface of one end side of the joint plate 10, and on one of the building blocks, It is comprised of a protruding engagement piece 12 that engages with the engaged portion 18 .

この位置決め手段１１は、目地プレート１０が前後方向に移動しないように拘束するように形成されており、被係合部１８の前後方向の壁面に係合片１２の前後方向の側面が線接触又は面接触するように形成されている。なお、被係合部１８の前後方向の内壁面の両側面に係合片１２の前後方向の側面が当接してもよいが、少なくとも勾配の高い方の内壁面と係合片１２の前後方向の側面が線接触又は面接触するように形成すればどのような形状に形成してもよい。 This positioning means 11 is formed to restrain the joint plate 10 from moving in the front-rear direction, and the front-rear side surface of the engaging piece 12 is in line contact with the front-rear wall surface of the engaged portion 18 or It is formed so that it makes surface contact. Note that the front and rear side surfaces of the engagement piece 12 may come into contact with both sides of the inner wall surface of the engaged portion 18 in the front and rear direction, but at least the inner wall surface of the engagement piece 12 that has a higher slope in the front and rear direction It may be formed into any shape as long as the side surfaces thereof are in line contact or surface contact.

本実施形態では、被係合部１８は平面視において略四角形状に形成され、側面視においては勾配の高い方の上部の角が鋭角となるような略四角形状に形成され、係合片１２もこの被係合部に対応するように平面視略四角形状で、側面視においては上部が鋭角となるような形状に形成されている。 In the present embodiment, the engaged portion 18 is formed in a substantially square shape in a plan view, and in a side view, in a substantially square shape such that the upper corner of the higher slope is an acute angle. In order to correspond to the engaged portion, the upper portion has a substantially rectangular shape when viewed from above, and the upper portion thereof is formed at an acute angle when viewed from the side.

ところで、位置決め手段１１は目地プレート１０の前後方向の移動を阻害するように形成されるが、目地プレート１０の他端部が上方へ回動する場合には、その動きを阻害しないような形状とすることが望ましい。このため、少なくとも係合片の他方の躯体４側の側面には、好ましくは一方の躯体３側へ傾斜する傾斜面状に形成することが望ましい。 By the way, the positioning means 11 is formed so as to obstruct the movement of the joint plate 10 in the front-rear direction, but when the other end of the joint plate 10 rotates upward, the positioning means 11 is formed in a shape that does not obstruct the movement. It is desirable to do so. For this reason, it is desirable that at least the side surface of the engagement piece on the other frame 4 side is formed into an inclined surface shape that is preferably inclined toward the one frame 3 side.

地震で左右の躯体３、４が左右方向に揺れ動き目地部２が狭くなると、図７に示すように、目地プレート１０の他端部が第２の目地プレート支持部８の乗り上げ傾斜面７により目地プレート１０の一端部側の上端部付近を支点に上方にせり上がり地震による揺れ動きを吸収する。 When the left and right building blocks 3 and 4 sway in the left-right direction due to an earthquake and the joint portion 2 narrows, the other end of the joint plate 10 runs over the second joint plate support portion 8 and the inclined surface 7 closes the joint, as shown in FIG. The plate 10 rises upward using the upper end of the plate 10 as a fulcrum 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目地部２が広くなると、図８に示すように、目地プレート１０の他端部が第２の目地プレート支持部８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 building blocks 3 and 4 sway in the left-right direction due to an earthquake and the joint portion 2 widens, the other end of the joint plate 10 slides on the upper surface of the second joint plate support portion 8 in the left-right direction, as shown in FIG. , absorbs the shaking motion caused by earthquakes.

図示しないが地震によって左右の躯体３、４が異なる前後方向に揺れ動くと、目地プレート１０は一方の躯体３に追従するように動き、地震による揺れ動きを吸収する。このとき、位置決め手段１１に地震による荷重が加わるため、目地プレート１０の杭ケース９や係止杭５に荷重が加わることを防止でき、これらの部品が破損等することを防止できる。 Although not shown, when the left and right building blocks 3 and 4 shake in different front and back directions due to an earthquake, the joint plate 10 moves to follow one of the building blocks 3 and absorbs the shaking movement caused by the earthquake. At this time, since the load due to the earthquake is applied to the positioning means 11, it is possible to prevent the load from being applied to the pile case 9 and the locking pile 5 of the joint plate 10, and it is possible to prevent these parts from being damaged.

［発明を実施するための異なる形態］
次に、図９乃至図１２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. 9 to 12 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９乃至図１２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、杭ケース９の前後方向の側面に突出して略当接する当接部１９を設けた係止杭５Ａと、前記杭ケース９とで位置決め手段１１Ａを構成した点で、このような位置決め手段１１Ａを備える床用目地装置１Ａにしても、前記本発明を実施するための第１の形態と同様な作用効果が得られる。ところで、本実施形態では、被係合部１８を有さない目地プレート１０Ａが用いられている。 In the second embodiment of the present invention shown in FIGS. 9 to 12, the main difference from the first embodiment of the present invention is that the pile case 9 has an approximately In that the positioning means 11A is constituted by the locking pile 5A provided with the abutting part 19 and the pile case 9, the floor joint device 1A including such a positioning means 11A can also be adapted to the present invention. The same effects as in the first embodiment can be obtained. By the way, in this embodiment, the joint plate 10A that does not have the engaged portion 18 is used.

この当接部１９は、本実施形態では、係止杭５Ａの上端部付近に突出するように設けられており、勾配が高い方の杭ケース９の前後方向の側面に略当接する。略当接するとは、接触している状態だけでなく、僅かな間隙を有して接近している状態も含まれる。位置決め手段１１Ａとしては当接部１９が接触することが望ましいが、僅かな間隙を有しているだけであれば、目地部２が開口するほど目地プレート１０Ａが前後方向に移動することは防止でき、発明の課題を解決することができる。 In this embodiment, this contact portion 19 is provided so as to protrude near the upper end of the locking pile 5A, and substantially contacts the side surface in the front-rear direction of the pile case 9 with a higher slope. "Substantially in contact" includes not only a state in which they are in contact, but also a state in which they are close to each other with a slight gap. It is desirable that the abutting portion 19 contacts the positioning means 11A, but if there is only a small gap, it is possible to prevent the joint plate 10A from moving in the front-rear direction to the extent that the joint portion 2 opens. , the problem of the invention can be solved.

本実施形態では、当接部１９を係止杭５Ａの上端部付近のみに形成しているが、例えば、目地プレート１０Ａの回動を阻害しない程度に当接部１９の寸法を大きくしてもよい。また、すべての係止杭５Ａに当接部１９を形成しているが、目地プレート１０の１対の杭ケース９のうちいずれか一方のみに当接部１９が当接するように形成してもよい。この当接部１９は、係止杭５Ａと一体的に形成してもよく、係止杭５Ａに目地プレート１０Ａを係止した後、溶接、ボルトやビスで固定してもよい。 In this embodiment, the contact portion 19 is formed only near the upper end of the locking pile 5A, but for example, the size of the contact portion 19 may be increased to the extent that rotation of the joint plate 10A is not inhibited. good. Further, although the contact portions 19 are formed on all of the locking piles 5A, the contact portions 19 may be formed so as to contact only one of the pair of pile cases 9 of the joint plate 10. good. This contact portion 19 may be formed integrally with the locking pile 5A, or may be fixed by welding, bolts, or screws after the joint plate 10A is locked to the locking pile 5A.

係止杭５Ａにボルトやビスにより当接部１９を固定する場合には、杭ケース９の寸法に誤差が生じている場合や、杭ケースの仕様がことなっても内壁面に確実に当接できるよう、様々な寸法の当接部１９を準備しておき、適切な厚さ（寸法）の当接部１９を固定することにより、より効果的に目地プレート１０Ａの前後方向への移動を防止することができる。 When fixing the contact part 19 to the locking pile 5A with bolts or screws, it is possible to ensure that it contacts the inner wall surface even if there is an error in the dimensions of the pile case 9 or the specifications of the pile case are different. By preparing abutting portions 19 of various dimensions and fixing the abutting portions 19 of appropriate thickness (dimensions), the movement of the joint plate 10A in the front-rear direction can be more effectively prevented. can do.

なお、本発明の実施形態では、係合片と被係合部を用いるものや、係止杭に当接部を設けた位置決め手段について説明したが、例えば一方の躯体に目地プレートの前後方向の側面が嵌合するような枠状の目地プレート設置部等を形成して位置決め手段としてもよいし、その他目地プレートの他端部が回動でき、かつ、目地プレートが一方の躯体に対して前後方向に移動しないような位置決め手段を用いることができる。 In addition, in the embodiments of the present invention, the positioning means using an engaging piece and an engaged part and a positioning means in which a contact part is provided on a locking pile have been described, but for example, a positioning means using a joint plate in the front and rear direction on one of the building blocks is explained. It may be used as a positioning means by forming a frame-shaped joint plate installation part that the sides fit into, or the other end of the joint plate can be rotated, and the joint plate can be moved back and forth relative to one of the building blocks. A positioning means that does not move in the direction can be used.

また、杭ケースの底部は開口しているが、この開口の前後方向の寸法を係止杭の前後方向の側面と略当接するような寸法とすることにより、係止杭と杭ケースにも位置決め手段の機能を持たせることができる。目地プレートが軽量であり、係止杭に大きな荷重がかからない場合には、このような杭ケースと係止杭のみで位置決め手段を構成しても良い。さらに、第１又は第２実施形態の位置決め手段とこのような杭ケースと係止杭を用いた位置決め手段を併用してもよい。 In addition, although the bottom of the pile case is open, by making the dimensions of this opening in the front-rear direction so that it almost touches the front-back side of the locking pile, the locking pile and the pile case can also be positioned. It can have the function of a means. If the joint plate is lightweight and a large load is not applied to the locking pile, the positioning means may be constituted by only such a pile case and the locking pile. Furthermore, the positioning means of the first or second embodiment and the positioning means using such a stake case and a locking stake may be used together.
