なお、左右方向とは図６（平面視）における左右方向であり、前後方向とは図６における上下方向、上下方向とは図７における上下方向をいう。 The left-right direction is the left-right direction in FIG. 6 (plan view), the front-back direction is the up-down direction in FIG. 6, and the up-down direction is the up-down direction in FIG. 7.

また、本発明において躯体とは、建物、道路、スラブ、エレベーターシャフト等の床用目地プレートを設置可能な建造物をいい、出入口とはドアや扉の設けられた出入口だけではなく、人や車両等が通行できる通路も含むものである。 Further, in the present invention, the skeleton refers to a building, a road, a slab, a building in which a floor joint plate such as an elevator shaft can be installed, and the doorway is not only a door or an doorway provided with a door, but also a person or vehicle. It also includes a passageway for traffic etc.

本実施形態の床用目地プレート１は、図１乃至図３に示すように、例えば、目地プレート本体６と、該目地プレート本体６の一端部側に設けられた取付部７と、前記目地プレート本体６に形成され、目地部２の下部との通気性を確保することができる通気部８と、目地プレート本体６の他端部側にヒンジ部材１０を介して設けられたカバープレート１１とを有している。 As shown in FIGS. 1 to 3, the floor joint plate 1 of the present embodiment includes, for example, a joint plate body 6, a mounting portion 7 provided on one end side of the joint plate body 6, and the joint plate. A ventilation part 8 formed in the main body 6 and capable of ensuring air permeability with the lower part of the joint part 2, and a cover plate 11 provided on the other end side of the joint plate main body 6 via a hinge member 10. Have

目地プレート本体６は、図４に示すように、金属製で浅皿状に形成され、一端部側の一部に開口部９が形成された枠部材１２と、目地プレート本体６の一端部側（例えば端部）の両側部に形成され、その底面にピン挿入孔１３を有する取付部７としてのピンボックス７と、枠部材１２の内部に多数のバーで構成された格子状（平面視方形状、矩形状、ひし形状、三角形状、ハニカム状等）のリブ１４とで構成されており、このリブ１４の間の隙間の連通孔２１と開口部９が連通し通気部８となる。この通気部８は目地プレート本体６を目地部２に設置した際に、該目地部２の上部に位置するように形成されている。
また、この開口部９が形成されていない枠部材１２の底面はカバー部２２となり、通気部８が躯体４の床面に接触することを防止している。すなわち、カバー部２２は目地プレート本体６の枠部材１２に一体的に設けられている。 As shown in FIG. 4, the joint plate main body 6 is made of metal in the shape of a shallow dish, and has a frame member 12 having an opening 9 formed in a part on one end side thereof, and one end side of the joint plate main body 6. A pin box 7 as a mounting portion 7 having pin insertion holes 13 formed on both sides of the end portion (for example, an end portion), and a grid shape (plan view) formed of a large number of bars inside the frame member 12. The ribs 14 have a shape, a rectangular shape, a rhombus shape, a triangular shape, a honeycomb shape, or the like), and the communication holes 21 and the openings 9 in the gaps between the ribs 14 serve as the communication vents 8. The ventilation part 8 is formed so as to be located above the joint part 2 when the joint plate body 6 is installed on the joint part 2.
Further, the bottom surface of the frame member 12 in which the opening 9 is not formed serves as the cover portion 22 and prevents the ventilation portion 8 from coming into contact with the floor surface of the body 4. That is, the cover portion 22 is provided integrally with the frame member 12 of the joint plate body 6.

ところで、このリブ１４は、本実施形態では、左右方向に延在するように設けられたベアリングバー１４ａと、このベアリングバー１４ａに略直行するように溶接等により固定されたクロスバー１４ｂとからなり、多数の連通孔２１はそれぞれ平面視方形状又は矩形状であり、全体として外観上格子状となっている。 By the way, in the present embodiment, the rib 14 includes a bearing bar 14a provided so as to extend in the left-right direction and a cross bar 14b fixed by welding or the like so as to be substantially orthogonal to the bearing bar 14a. The plurality of communication holes 21 each have a quadrangular shape in plan view or a rectangular shape, and have a lattice shape in appearance as a whole.

付言すると、ベアリングバー１４ａを左右方向に延在するように設け、クロスバー１４ｂをこのベアリングバー１４ａに直行するように設けてもよく、あるいはベアリングバー１４ａのような板材のみを格子状に組み合わせてリブ１４を形成してもよい。 In addition, the bearing bar 14a may be provided so as to extend in the left-right direction, and the cross bar 14b may be provided so as to be orthogonal to the bearing bar 14a. Alternatively, only plate members such as the bearing bar 14a may be combined in a grid pattern. The ribs 14 may be formed.

このベアリングバー１４ａとクロスバー１４ｂの両端部は、枠部材１２の内壁面（又はピンボックス７）に溶接等により固定されている。 Both ends of the bearing bar 14a and the cross bar 14b are fixed to the inner wall surface of the frame member 12 (or the pin box 7) by welding or the like.

なお、ベアリングバー１４ａは断面Ｈ鋼状のものを用いてもよく、クロスバー１４ｂにはツイストバーを用いてもよい。
ところで、開口部９は、目地プレート本体６の一端部側から全長の１／３乃至約半分程度に設けられる。 The bearing bar 14a may have an H-shaped cross section, and the crossbar 14b may be a twist bar.
By the way, the opening 9 is provided from one end side of the joint plate body 6 to about 1/3 to about half of the entire length.

このように開口部９を設けることにより、目地プレート本体６の他端部側はカバー部２２に覆われ、床用目地プレート１の他端部側を支持する躯体４の床面に通気部８が接触しないので、目地部２を塞ぐように床用目地プレート１を設けた（目地部２に設置した）場合に、床用目地プレート１の他端部側を支持する躯体４の床面（第２の目地プレート支持部１６）を通気部８によって損傷させることがない。 By providing the opening 9 in this manner, the other end side of the joint plate body 6 is covered with the cover portion 22, and the ventilation portion 8 is provided on the floor surface of the skeleton 4 supporting the other end portion of the floor joint plate 1. When the floor joint plate 1 is provided so as to block the joint portion 2 (installed on the joint portion 2), the floor surface of the skeleton 4 supporting the other end side of the floor joint plate 1 ( The second joint plate support portion 16) is not damaged by the ventilation portion 8.

また、このカバー部２２は、目地プレート本体６の他端部側から少なくとも全長の約半分程度を覆うように形成されている。通常、このような床用目地プレート１では、目地プレート本体６の他端部側から全長の約半分が躯体４に支持されるため、躯体４の上面が通気部８に接触することがなく、一端部側（取付部７を有する側）の端部から全長の約半分程度はカバー部２２で覆われていないため、目地部２を塞ぐように床用目地プレート１を設けた（目地部２に設置した）場合に、目地部２の上部に位置する通気部８を通じて目地部２の下部の空気の通気性を十分に確保することができる。 The cover portion 22 is formed so as to cover at least about half of the entire length from the other end side of the joint plate body 6. Usually, in such a floor joint plate 1, since about half of the entire length from the other end side of the joint plate body 6 is supported by the skeleton 4, the upper surface of the skeleton 4 does not come into contact with the ventilation portion 8, About half of the entire length from the end on the one end side (the side having the mounting portion 7) is not covered with the cover portion 22, so the floor joint plate 1 is provided so as to close the joint portion 2 (joint portion 2 In this case, it is possible to sufficiently secure the air permeability of the lower portion of the joint portion 2 through the ventilation portion 8 located above the joint portion 2.

すなわち、目地プレート本体６を目地部２に設置した際に、通常時（図４の状態、一方と他方の躯体３、４間の目地部に設置された状態で、かつ、地震等により左右の躯体３、４が揺れ動いていない状態）において、床用目地プレート１の他端部側を支持する躯体４の床面（後述する第２の目地プレート支持部１６）と接する部位にのみカバー部２２を設けることにより、床面の損傷を防止することができ、かつ、目地部２の上部に通気部８が位置するので目地部２の下部の空気の通気性を十分に確保することができる。 That is, when the joint plate body 6 is installed in the joint portion 2, in a normal state (in the state of FIG. 4, in a state of being installed in the joint portion between the one and the other of the frames 3 and 4, and due to an earthquake or the like, the In a state where the skeletons 3 and 4 are not swaying), the cover portion 22 is provided only at a portion in contact with the floor surface of the skeleton 4 that supports the other end portion side of the floor joint plate 1 (a second joint plate support portion 16 described later). By providing the above, it is possible to prevent the floor surface from being damaged, and since the ventilation portion 8 is located above the joint portion 2, it is possible to sufficiently secure the air permeability of the lower portion of the joint portion 2.

ところで、目地プレート本体６を設置した際に、目地部２の上部に位置する部位の一部をカバー部２２で覆うような構成（目地プレート本体６の底面の他端部側から半分以上を覆うような構成）にしてもよい。このような場合であっても、目地プレート本体６の一端部側の一部分は目地部２と通気部８を介して通気性を確保できる。 By the way, when the joint plate main body 6 is installed, a part of the upper portion of the joint portion 2 is covered with the cover portion 22 (more than half is covered from the other end side of the bottom surface of the joint plate main body 6). It may be configured). Even in such a case, a part of the joint plate body 6 on the one end side can ensure the air permeability through the joint portion 2 and the ventilation portion 8.

床用目地装置５は、図６及び図７に示すように、一方の躯体３に設けられた第１の目地プレート支持部１５と、他方の躯体４に設けられた第２の目地プレート支持部１６と、第１の目地プレート支持部１５に設けられた取付手段１７としての枢支ピン１７と、該枢支ピン１７が取付部７としてのピンボックス７に挿入されるとともに、前記第１の目地プレート支持部１５に一端部が支持され、かつ、前記第２の目地プレート支持部１６に他端部が支持された床用目地プレート１とで構成されている。 As shown in FIGS. 6 and 7, the floor joint device 5 includes a first joint plate support portion 15 provided on one of the frame bodies 3 and a second joint plate support portion provided on the other frame body 4. 16, a pivot pin 17 as a mounting means 17 provided on the first joint plate supporting portion 15, the pivot pin 17 is inserted into the pin box 7 as the mounting portion 7, and The floor joint plate 1 has one end supported by the joint plate support portion 15 and the other end supported by the second joint plate support portion 16.

第１の目地プレート支持部１５は、例えば図７に示すように、一方の躯体３の端部に前後方向に延在する凹所状に形成されており、床用目地プレート１のピンボックス７に挿入される枢支ピン１７が固定されている。 As shown in FIG. 7, for example, the first joint plate supporting portion 15 is formed in a recess shape extending in the front-rear direction at the end portion of the one frame 3, and the pin box 7 of the floor joint plate 1 is formed. The pivot pin 17 to be inserted into is fixed.

なお、第１の目地プレート支持部１５は、本実施形態のように一方の躯体３に一体的に形成してもよいが、アングル状又はクランク状の金具を一方の躯体３の壁面にボルト等で固定し、この金具を第１の目地プレート支持部１５としてもよい。 The first joint plate support portion 15 may be formed integrally with the one frame 3 as in the present embodiment, but an angle-shaped or crank-shaped metal fitting is attached to the wall surface of the one frame 3 by a bolt or the like. Alternatively, the metal fitting may be used as the first joint plate supporting portion 15.

前記枢支ピン１７の取り付け状態については、特に図示していないが、鉄板等に溶接により固定され、この鉄板をボルト等で第１の目地プレート支持部１５に固定される。 Although not shown, the pivot pin 17 is attached to an iron plate or the like by welding, and the iron plate is fixed to the first joint plate supporting portion 15 with bolts or the like.

この第２の目地プレート支持部１６は、例えば図７に示すように、他方の躯体４の目地部２側の端部に形成された前後方向に延在する凹所状の部位で、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、床用目地プレート１が乗り上げる乗り上げ傾斜面１８が形成されており、この第２の目地プレート支持部１６の上面には、金属製の支持プレート１９が設けられている。 The second joint plate support portion 16 is, for example, as shown in FIG. 7, a recessed portion extending in the front-rear direction formed at the end portion of the other skeleton 4 on the joint portion 2 side. The end opposite to 2 is provided with a riding slope 18 on which the floor joint plate 1 rides when the joint 2 becomes narrow due to an earthquake. The upper surface of the second joint plate support 16 is formed. A support plate 19 made of metal is provided on the.

床用目地プレート１は、その一端部が第１の目地プレート支持部１７に支持されると共に、その他端部が第２の目地プレート支持部１６に直接又は本実施形態のように、すのこ状の支持プレート１９を介して間接的に支持された状態で目地部２の前後方向に複数個、略隙間なく設けられている。 One end of the floor joint plate 1 is supported by the first joint plate supporting portion 17, and the other end thereof is directly connected to the second joint plate supporting portion 16 or, like the present embodiment, in the shape of a sludge. A plurality of joints 2 are provided in the front-rear direction of the joint portion 2 in a state of being indirectly supported via the support plate 19 with substantially no space.

地震で躯体３、４が左右方向に揺れ動き目地部２が狭くなると、図８に示すように、床用目地プレート１は第２の目地プレート支持部１６の乗り上げ傾斜面１９を乗り上げて地震による揺れ動きを吸収する。 When the skeletons 3 and 4 swing to the left and right due to the earthquake and the joint portion 2 becomes narrow, the floor joint plate 1 rides on the riding slope 19 of the second joint plate supporting portion 16 and sways due to the earthquake, as shown in FIG. Absorbs.

このとき、目地プレート本体６は一端部側を支点に他端部側が上方へ回動し、目地プレート本体６の底面と他方の躯体４の第２の目地プレート支持部１６とは接触しないため、第２の目地プレート支持部１６が通気部８のエッジにより削られて損傷することはない。 At this time, since the joint plate body 6 pivots upward on the other end side with one end side as a fulcrum, the bottom surface of the joint plate body 6 and the second joint plate supporting portion 16 of the other frame 4 do not come into contact with each other, The second joint plate support portion 16 is not scratched and damaged by the edge of the ventilation portion 8.

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９に示すように、床用目地プレート１は第２の目地プレート支持部１６上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ことができる。このとき、目地プレート本体６はカバー部２２を介して第２の目地プレート支持部１６と接触しているため、第２の目地プレート支持部１６が通気部８のエッジにより削られて損傷することはない。 When the skeletons 3 and 4 sway in the left-right direction due to the earthquake and the joint portion 2 becomes wide, the floor joint plate 1 slides in the left-right direction on the second joint plate supporting portion 16 as shown in FIG. The shaking motion can be absorbed. At this time, since the joint plate body 6 is in contact with the second joint plate support portion 16 via the cover portion 22, the second joint plate support portion 16 is scraped by the edge of the ventilation portion 8 and damaged. There is no.

また、図示しないが、地震で躯体３、４が異なる前後方向に揺れ動いた場合にも、床用目地プレート１は第２の目地プレート支持部１６上を前後方向にスライド移動し、地震による揺れ動きを吸収し、このときも目地部２が広くなった場合と同様に、目地プレート本体６はカバー部２２を介して第２の目地プレート支持部１６と接触しているため、第２の目地プレート支持部１６が通気部８のエッジにより削られて損傷することはない。 Further, although not shown, even when the skeletons 3 and 4 sway in different front-rear directions due to an earthquake, the floor joint plate 1 slides on the second joint plate support portion 16 in the front-rear direction to prevent swaying movements caused by the earthquake. Since the joint plate main body 6 is in contact with the second joint plate support portion 16 through the cover portion 22 at this time as in the case where the joint portion 2 is widened, the second joint plate support is also performed. The part 16 is not scratched and damaged by the edge of the ventilation part 8.
