The horizontal frame ridges and the vertical frame ridges disposed at both ends in the longitudinal direction of the both horizontal frame ridges are formed into a rectangular frame shape, and the opening surrounded by each frame ridge is blocked by a blocking member. A pair of fences are juxtaposed in a state where a part of each horizontal frame ridge of each of the fences overlaps in the front and rear directions, and the respective horizontal frame ridges facing each other in the front and back slide in the longitudinal direction via the sliding connection means. In the joint expansion / contraction fence in which one end located on the building housing side of both fence bodies is coupled to the building housing so as to be horizontally rotatable, the sliding connection means includes an engagement groove and A horizontal frame rod integrally formed with an engagement protrusion having a shape engageable with the engagement groove at the vertical position of one side wall surface; The concavity groove and the engagement protrusion are arranged to face each other so as to be point-symmetric in side view, and the engagement protrusion groove of the other horizontal frame rod is engaged with the engagement groove of one horizontal frame rod, And, by engaging the engaging ridges of one horizontal frame rod with the engaging concave grooves of the other horizontal frame rod, the horizontal frame rods facing each other before and after the two fence bodies are connected to each other so as to be slidable in the longitudinal direction. It is an expansion / contraction fence characterized by being made.
ここで、係合凹溝と該係合凹溝に係合可能な形状の係合突条とが一側壁面の上下位置に形成された横枠杆を一対とし、一方の横枠杆の上下を反転させて両横枠杆を対向させることにより、夫々の横枠杆の一側壁面に形成された係合凹溝と係合突条とを側面視において点対称とすることができる。   Here, a pair of horizontal frame ridges in which an engagement groove and an engagement protrusion shaped to be engageable with the engagement groove are formed at the upper and lower positions of one side wall surface, By reversing and making both horizontal frame rods face each other, the engagement groove and the engagement protrusion formed on one side wall surface of each horizontal frame rod can be made point-symmetric in a side view.
また、両柵体の建物躯体側に位置する一端を、該建物躯体に水平回動可能に連結するには、該建物躯体に支軸を介して連結したり、建物躯体の床面に立設された支柱を介して連結することができる。   In addition, to connect one end of both fences located on the building frame side to the building frame so as to be able to rotate horizontally, it is connected to the building frame via a support shaft or is erected on the floor of the building frame. It is possible to connect via the supported struts.
さらに、柵体の各枠杆により囲繞された開口部を遮断する遮断部材は、複数の縦桟や格子或いはパネルで構成され得る。   Further, the blocking member that blocks the opening surrounded by each frame rod of the fence body may be configured by a plurality of vertical bars, lattices, or panels.

次に、本発明の要部について説明する。
両柵体12,12の各横枠杆10,10は、図6(A)に示すように、断面略H形を呈するアルミニウム合金の押出し型材からなり、その一側壁面には断面略C字形を呈する係合凹溝17と該係合凹溝17に係合可能な断面略T字形を呈する係合突条18とが上下方向に位置して一体形成されている。そして、この横枠杆10,10を一対とし、図6(B)に示すように、係合凹溝17と係合突条18とが側面視において点対称となるように両横枠杆10,10が対向配置されている。ここで、点対称とは、図形Aを点Pのまわりに一八○度回転して図形Bが得られるとき、AとBは互いに点対称であるというと定義され(広辞苑より)、ここでは、一方の横枠杆10(図中右側)の上下を反転させて両横枠杆10,10の係合凹溝17と係合突条18とを対向させることにより、横枠杆10,10に夫々形成された係合凹溝17と係合突条18とを側面視において点対称としている。そして、このように係合凹溝17と係合突条18とが側面視において点対称となるように両柵体12,12の上下位置で横枠杆10,10を夫々対向配置して、図5に示すように、一方の横枠杆10の係合凹溝17に側方から他方の横枠杆10の係合突条18を係合し、かつ一方の横枠杆10の係合突条18を側方から他方の横枠杆10の係合凹溝17に係合することによって、両柵体12,12の前後で対向する各横枠杆10,10相互を長手方向にスライド可能に連結するようにしている。これにより、各横枠杆10,10の摺動連結手段15が構成されている。
Next, the main part of the present invention will be described.
As shown in FIG. 6 (A), the horizontal frame rods 10, 10 of both the fence bodies 12, 12 are made of an extruded material of an aluminum alloy having a substantially H-shaped cross section, and one side wall surface has a substantially C-shaped cross section. And an engaging protrusion 18 having a substantially T-shaped cross section engageable with the engaging groove 17 are integrally formed in the vertical direction. Then, the horizontal frame rods 10 and 10 are paired, and as shown in FIG. 6 (B), both the horizontal frame rods 10 so that the engagement grooves 17 and the engagement protrusions 18 are point-symmetric in a side view. , 10 are opposed to each other. Here, point symmetry is defined as A and B being point-symmetric with each other when the figure B is obtained by rotating the figure A around the point P by 18 ° (here, from Kojien) The horizontal frame rods 10, 10 are made by reversing the upper and lower sides of one horizontal frame rod 10 (right side in the figure) so that the engaging grooves 17 and the engaging protrusions 18 of both horizontal frame rods 10, 10 face each other. The engagement concave grooves 17 and the engagement protrusions 18 formed respectively in FIG. Then, the horizontal frame rods 10 and 10 are respectively arranged opposite to each other at the upper and lower positions of the fence bodies 12 and 12 so that the engagement groove 17 and the engagement protrusion 18 are point-symmetric in a side view as described above. As shown in FIG. 5, the engagement protrusion 18 of the other horizontal frame rod 10 is engaged with the engagement groove 17 of the one horizontal frame rod 10 from the side, and the engagement of the one horizontal frame rod 10 is engaged. By engaging the protrusion 18 with the engaging groove 17 of the other lateral frame rod 10 from the side, the lateral frame rods 10, 10 facing each other before and after the fence bodies 12, 12 slide in the longitudinal direction. I try to connect them as possible. Thereby, the sliding connection means 15 of each horizontal frame rod 10 and 10 is comprised.
また、両柵体12,12の上部の横枠杆10,10には、該横枠杆10,10の上面を覆うカバー体19,19が夫々配設されている。各カバー体19は、断面略コ字形を呈するアルミニウム合金の押出し型材からなり、各カバー体19の前後両側壁縁20,20と横枠杆10の前後両側壁縁21,21とに夫々一体形成された相互に係合可能な一対の係合爪縁22,23相互の係合によって、前記カバー体19が横枠杆10に夫々保持されている。   In addition, cover bodies 19, 19 that cover the upper surfaces of the horizontal frame rods 10, 10 are disposed on the horizontal frame rods 10, 10 at the tops of both fence bodies 12, 12, respectively. Each cover body 19 is made of an extruded material of an aluminum alloy having a substantially U-shaped cross section, and is integrally formed on the front and rear side wall edges 20 and 20 of each cover body 19 and the front and rear side wall edges 21 and 21 of the horizontal frame rod 10, respectively. The cover body 19 is held by the horizontal frame rod 10 by the mutual engagement between the pair of engaging claw edges 22 and 23 that can be engaged with each other.
かかる構成からなる目地用伸縮柵1にあって、地震時に、隣接する建物躯体が離近方向(目地sに直交する方向)に相対変位すると、両柵体12,12が各横枠杆10,10の摺動連結手段15を介してその変位量に応じて伸縮し、前記離近方向の相対変位に追従する。また、隣接する建物躯体が前後方向(目地sに沿う方向)に相対変位すると、両柵体12,12が伸縮するとともに、両柵体12,12の端部が支持杆16,16に対して水平方向に回動して、その相対変位に追従する。これにより、目地用伸縮柵1は、隣接する建物躯体の離近方向及び前後方向の各相対変位に無理なく追従し、両柵体12,12の遮断部材13,13によって、通路5の側部の間隙部9を支障なく遮断することができる。   In the joint extension telescopic fence 1 having such a configuration, when the adjacent building frame is relatively displaced in the near direction (a direction perpendicular to the joint s) at the time of an earthquake, the two fence bodies 12 and 12 are respectively connected to the horizontal frame fences 10 and 10. The tenth sliding connecting means 15 expands and contracts in accordance with the amount of displacement, and follows the relative displacement in the near and far direction. Further, when the adjacent building frame is relatively displaced in the front-rear direction (the direction along the joint s), both the fence bodies 12 and 12 are expanded and contracted, and the ends of the both fence bodies 12 and 12 are opposed to the support rods 16 and 16. It rotates horizontally and follows its relative displacement. Thereby, the expansion joint 1 for joints follows the relative displacement of the adjacent building frame in the direction of separation and the front-rear direction without difficulty, and the side portions of the passage 5 by the blocking members 13 and 13 of both the fence bodies 12 and 12. The gap 9 can be blocked without any trouble.
そして、両柵体12,12の前後で対向する各横枠杆10,10相互を長手方向にスライド可能に連結する摺動連結手段15が、上述したように、係合凹溝17と該係合凹溝17に係合可能な形状の係合突条18とを一側壁面の上下位置に一体形成した横枠杆10,10を、該係合凹溝17と係合突条18とが側面視において点対称となるように対向配置して、一方の横枠杆10の係合凹溝17に他方の横枠杆10の係合突条18を係合し、かつ一方の横枠杆10の係合突条18を他方の横枠杆10の係合凹溝17に係合することによって構成されていることにより、従来の摺動連結手段を構成するスライド芯材f(図11参照)が不要となり、これによって従来構成に比して部品点数が少なく、製作コストを低減でき、また、スライド芯材fの固定作業が不要であるため、両横枠杆10,10相互の組み付けを簡単に行うことができる。   Then, as described above, the sliding connecting means 15 that connects the horizontal frame rods 10 and 10 opposed to each other before and after the two fence bodies 12 and 12 is slidable in the longitudinal direction. The horizontal frame rods 10 and 10 formed integrally with the upper and lower positions of one side wall surface of the engagement protrusions 18 that can be engaged with the mating recess grooves 17 are formed into the engagement recess grooves 17 and the engagement protrusions 18. Oppositely arranged so as to be point-symmetric in a side view, the engaging groove 18 of the other horizontal frame rod 10 is engaged with the engaging groove 17 of the one horizontal frame rod 10, and one horizontal frame rod 10 is formed by engaging the engaging protrusions 18 with the engaging grooves 17 of the other horizontal frame rod 10, so that the slide core material f (see FIG. 11) that constitutes the conventional sliding connecting means. ) Is no longer required, which reduces the number of parts compared to the conventional configuration and reduces manufacturing costs. For fixing work it is not necessary, it is possible to perform the assembling of the two lateral frame rod 10, 10 each other easily.
図7,図8は、第二実施例を示し、この第二実施例は、摺動連結手段15の構成を若干変更したものである。即ち、図8に示すように、横枠杆10の一側壁面には、断面略L字形を呈する係合凹溝17’と該係合凹溝17’に係合可能な断面略L字形を呈する係合突条18’とが上下方向に位置して一体形成されている。そして、図7に示すように、この係合凹溝17’と係合突条18’とが側面視において点対称となるように両柵体12,12の上下位置で横枠杆10,10を夫々対向配置して、一方の横枠杆10の係合凹溝17’に側方から他方の横枠杆10の係合突条18’を係合し、かつ一方の横枠杆10の係合突条18’を側方から他方の横枠杆10の係合凹溝17’に係合することによって、両柵体12,12の前後で対向する各横枠杆10,10相互が長手方向にスライド可能に連結されている。その他、第一実施例と共通する構成部分については第一実施例と同一符号を付して重複説明を省略する。   7 and 8 show a second embodiment, in which the configuration of the sliding connection means 15 is slightly changed. That is, as shown in FIG. 8, on one side wall surface of the horizontal frame rod 10, there is an engaging groove 17 ′ having a substantially L-shaped section and a substantially L-shaped section that can be engaged with the engaging groove 17 ′. The engaging protrusion 18 ′ to be presented is integrally formed so as to be positioned in the vertical direction.
