Description

本願発明は振止め具およびその取り付け方法に関するものである。   The present invention relates to a brace and a mounting method thereof.

ふところの高い天井ではスラブ下面から吊り下げられた吊りボルトが長くなるため、地震時の水平力によって天井が大きく振られて落下するおそれがあった。そこで、図8に示すように、高さ1500mm以下ごとに水平振止め材36を縦横1800mmごとに設置し、要所には斜め振止め材37を溶接で取り付けていた。しかし、斜め振れ止め材37の上側の溶接は、天井用足場38から手が届かないためウマ39を使うなどの危険作業になりがちであり、しかも部材断面寸法が小さいために十分な溶接ができず、強度的にも不安定になるという問題があった。さらに、その他の振止め具としては、例えば特開2002−38649号の発明が知られている。
特開2002−38649号公報
Since the hanging bolts hung from the lower surface of the slab become long on the high ceiling, there was a risk that the ceiling would be greatly shaken by the horizontal force at the time of the earthquake and dropped. Therefore, as shown in FIG. 8, the horizontal anti-vibration material 36 is installed every 1800 mm in length and width every 1500 mm or less in height, and the oblique anti-vibration material 37 is attached to the main points by welding. However, the welding on the upper side of the slant anti-rest material 37 tends to be a dangerous work such as using a horse 39 because the hand cannot be reached from the ceiling scaffold 38, and since the cross-sectional dimension of the member is small, sufficient welding can be performed. In addition, there is a problem that the strength becomes unstable. Furthermore, as another anti-rest device, for example, the invention of JP-A-2002-38649 is known.
JP 2002-38649 A

しかし、上記のような振止め具は足場上でウマを使うなどの危険作業になりがちであり、しかも細い部材への溶接作業であるため十分な強度を得ることができなかった。   However, the above-mentioned brace is apt to be a dangerous work such as using a horse on a scaffold, and since it is a welding work to a thin member, sufficient strength cannot be obtained.

本願発明はこれらの問題に鑑みてなされたものであり、その目的は、簡単に取り付けでき、かつ強度が高い振止め具およびその取り付け方法を提供することである。   The present invention has been made in view of these problems, and an object of the present invention is to provide a brace that can be easily attached and has high strength and a method for attaching the same.

以上の課題を解決するための天井内における振止め具は、スラブ下面から吊り下げられた吊りボルトを挿入する挿入孔を備えた筒体の外周面に取付片が設けられ、該取付片には斜め振止め材の一端部が回転自在に取り付けられ、該斜め振止め材の他端部には、前記吊りボルトに隣接した吊りボルトに固定される固定片が取り付けられ、前記挿入孔の内側には、挿入孔に吊りボルトを挿入したときに筒体が下がるのを防ぐ固定手段が設けられたことを特徴とする。また固定手段は、挿入孔の内側に形成された下側が広く上側に向かって狭くなった収納部と、該収納部に収納されてスプリングで常時押し上げられている複数の掴み部材とからなり、該掴み部材は、筒体の下がる力によって吊りボルトを掴むことを含むものである。   In order to solve the above-described problems, a mounting bracket is provided on the outer peripheral surface of a cylindrical body having an insertion hole for inserting a suspension bolt suspended from the lower surface of the slab. One end of the diagonal anti-resting material is rotatably attached, and a fixing piece fixed to the suspension bolt adjacent to the suspension bolt is attached to the other end of the oblique anti-rest material, inside the insertion hole Is characterized in that a fixing means is provided for preventing the cylinder from lowering when a suspension bolt is inserted into the insertion hole. The fixing means includes a storage portion formed on the inner side of the insertion hole and having a lower side that is wide and narrows toward the upper side, and a plurality of gripping members that are stored in the storage portion and are constantly pushed up by a spring. The grasping member includes grasping the suspension bolt by the force of lowering the cylindrical body.

また振止め具の取り付け方法は、請求項1または2の振止め具の取り付け方法であり、スラブ下面から吊り下げられた吊りボルトを挿入孔に挿入して振止め具を取り付けた後、斜め振止め材を回転させて他端部を固定片で前記吊りボルトに隣接した吊りボルトに固定することを特徴とする。   Further, the mounting method of the brace is the mounting method of the brace according to claim 1 or 2, and after the suspension bolt is inserted into the insertion hole by inserting the suspension bolt suspended from the lower surface of the slab, The stopper is rotated, and the other end is fixed to a suspension bolt adjacent to the suspension bolt with a fixing piece.

以下、本願発明の振止め具およびその取り付け方法の実施の形態を図面に基づいて説明する。はじめに、振止め具について説明し、次に、この振止め具の取り付け方法について説明するが、各実施の形態において同じ構成は同じ符号を付して説明し、異なった構成は異なった符号を付して説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a brace and an attaching method thereof according to the present invention will be described with reference to the drawings. First, a description will be given of the brace, and then a method for attaching the brace will be described. In each embodiment, the same components are denoted by the same reference numerals, and different configurations are denoted by different symbols. To explain.

図1は第1の実施の形態の振止め具1である。この振止め具1はスラブ下面に適宜間隔をもって吊り下げた吊りボルト2間にわたってブレース材である斜め振止め材3を設置するものであり、筒体4とこの筒体4に回転自在に取り付けられた4本の斜め振止め材3とから構成されている。この斜め振止め材3は長ボルトであり、一端部が筒体4外周面の取付片5に設けられた回転板6にねじ込まれている。   FIG. 1 shows a brace 1 according to the first embodiment. The brace 1 is provided with an oblique brace 3 that is a brace material between suspension bolts 2 suspended at an appropriate interval on the lower surface of the slab, and is attached to the cylinder 4 and the cylinder 4 so as to be rotatable. And four diagonal anti-vibration members 3. The diagonal anti-vibration material 3 is a long bolt, and one end thereof is screwed into a rotating plate 6 provided on the mounting piece 5 on the outer peripheral surface of the cylindrical body 4.

この回転板6は一枚板を平面三角形に折り曲げ形成し、二枚に折り重なった先端部がピン7で取付片5に取り付けられている。したがって回転板6を中心に斜め振止め材3が回転するようになっている。このように斜め振止め材3は傘と同じように使用しない場合は下側に垂れた状態、すなわち閉じた状態になっており、使用する場合は回転して開いた状態になる。   The rotating plate 6 is formed by bending a single plate into a plane triangle, and the tip end portion that is folded into two is attached to the mounting piece 5 with a pin 7. Therefore, the diagonal anti-vibration material 3 rotates around the rotating plate 6. As described above, when the slant anti-vibration member 3 is not used in the same manner as an umbrella, the slant anti-vibration member 3 is in a state of hanging downward, that is, in a closed state.

一方、斜め振止め材3の他端部には固定片8が取り付けられているが、これを隣接した吊りボルト9に取り付けるには、一旦斜め振止め材3から取り外して吊りボルト9に取り付けた後に、該固定片8のナット10に斜め振止め材3の他端部をねじ込むものである。この固定片8における吊りボルト9が挿入された貫入孔11は、図2に示すように、中央を切り込み、この切込板12を互いに反対方向に折り曲げ形成し、この切込片12には吊りボルト9にかみ合う雌ネジ13が形成されている。   On the other hand, the fixed piece 8 is attached to the other end portion of the diagonal anti-vibration material 3. To attach this to the adjacent suspension bolt 9, it is once removed from the oblique anti-vibration material 3 and attached to the suspension bolt 9. Later, the other end of the diagonal anti-vibration material 3 is screwed into the nut 10 of the fixed piece 8. As shown in FIG. 2, the through hole 11 into which the suspension bolt 9 is inserted in the fixed piece 8 is cut at the center, and the cut plate 12 is bent in opposite directions. A female screw 13 that engages with the bolt 9 is formed.

また筒体4は、図3に示すように、吊りボルト2を挿入する挿入孔14を備え、この挿入孔14の内側下部には下側が広く上側が狭くなった収納部15が形成されている。そしてこの収納部15に固定手段である4つの掴み部材(または3つ)16が収納され、これらの掴み部材16が底板17との間に設けたスプリング18で常時押し上げられている。この掴み部材16も4つが合わさった状態で収納部15と同じ形状、すなわち下側が広く上側が狭くなっており、中央に吊りボルトの挿入部19が形成され、この挿入部19の内側に吊りボルト9にかみ合わされるネジ部20が形成されている。   Further, as shown in FIG. 3, the cylindrical body 4 includes an insertion hole 14 into which the suspension bolt 2 is inserted, and a storage portion 15 having a lower side wide and a narrow upper side is formed in an inner lower portion of the insertion hole 14. . Then, four gripping members (or three) 16 as fixing means are stored in the storage portion 15, and these gripping members 16 are always pushed up by a spring 18 provided between the bottom plate 17. When the four gripping members 16 are combined, the shape is the same as that of the storage portion 15, that is, the lower side is wide and the upper side is narrow, and a suspension bolt insertion portion 19 is formed at the center. 9 is formed.

したがって、掴み部材16がスプリング18で押し上げられているときには、内側に縮んで挿入部19を狭くする一方、下がったときには外側に広がって挿入部19を大きくするため、筒体4を吊りボルト2に沿って押し上げることができるが、押し下げることはできない。これは筒体4を押し上げるときは、掴み部材16が下がって挿入部19を大きくする一方、筒体4を押し下げるときは掴み部材16が上がって挿入部19を狭くするためである。   Accordingly, when the gripping member 16 is pushed up by the spring 18, the tube 4 is contracted inward to narrow the insertion portion 19, while when it is lowered, the insertion portion 19 is expanded outward to enlarge the insertion portion 19. Can be pushed up, but cannot be pushed down. This is because when the cylinder 4 is pushed up, the gripping member 16 is lowered to enlarge the insertion portion 19, while when the cylinder 4 is pushed down, the gripping member 16 is raised to narrow the insertion portion 19.

図4は第2の実施の形態の振止め具21を示したものである。この振止め具21は回転板23のみが第1の実施の形態の振止め具1と異なるものであり、これ以外は同じ構成である。この回転板23は底部側に補強板24が溶接されたL字形であり、一方がピン25で固定片8に接続され、他方の折曲片26には斜め振止め材3がねじ込まれている。   FIG. 4 shows a brace 21 according to the second embodiment. This brace 21 is different from the brace 1 of the first embodiment only in the rotating plate 23, and the other configuration is the same. The rotating plate 23 has an L shape in which a reinforcing plate 24 is welded to the bottom side. One of the rotating plates 23 is connected to the fixed piece 8 by a pin 25, and the oblique bent antistatic material 3 is screwed into the other bent piece 26. .

また図5は第3の実施の形態の振止め具22を示したものである。(1)の振止め具22は固定片27のみが第1の実施の形態の振止め具1と異なるものであり、これ以外は同じ構成である。この固定片27は吊りボルト9に水平に固定される水平片28と斜め振止め材3を接続する斜板29とからなり、該斜板29の折曲片30に斜め振止め材3がナット31で接続されている。この固定片27は吊りボルト9に固定しやすくなっている。また(2)の振止め具22は固定片27が吊りボルト9に水平に固定できるように、貫入孔11が第1の実施の形態の振止め具1と同じように、切込板12を互いに反対方向に折り曲げ、ここに雌ネジ13を形成したものである。   FIG. 5 shows a brace 22 according to the third embodiment. The brace 22 of (1) is different from the brace 1 of the first embodiment only in the fixed piece 27, and the other configuration is the same. The fixing piece 27 includes a horizontal piece 28 fixed horizontally to the suspension bolt 9 and a swash plate 29 connecting the oblique anti-vibration member 3. The oblique anti-vibration member 3 is attached to the bent piece 30 of the swash plate 29 with a nut. 31 is connected. The fixing piece 27 is easily fixed to the suspension bolt 9. Further, in the anti-vibration tool 22 of (2), the penetration hole 11 is formed with the notch plate 12 in the same manner as the anti-vibration tool 1 of the first embodiment so that the fixing piece 27 can be fixed horizontally to the suspension bolt 9. It is bent in opposite directions, and a female screw 13 is formed here.

次に、振止め具の取り付け方法を図6および図7に基づいて説明する。この取り付け方法は、第1の実施の形態の振止め具1を利用するものである。これはスラブ下面32から900mm程度の間隔で吊り下げられた、長さ1500mm以上の吊りボルト2に振止め具1を設置するものである。   Next, the attachment method of a brace is demonstrated based on FIG. 6 and FIG. This attachment method uses the brace 1 of the first embodiment. This is to install the brace 1 on the suspension bolt 2 having a length of 1500 mm or more suspended from the lower surface 32 of the slab at an interval of about 900 mm.

はじめに、同図の(1)に示すように、天井用足場33から作業者34が一つの吊りボルト2に筒体4を取り付ける。これは筒体4の挿入孔14に吊りボルト2を挿入し、該吊りボルト2に沿って筒体4を押し上げると、掴み材16が下がって挿入部19が広がるので、筒体4が自由に押し上げられる。そして、吊りボルト2の最上部、すなわちスラブ下面32に達するまで押し上げると、筒体4は掴み材16で下がらなくなる(下側に押し下げる力により掴み部材16が縮んで挿入部19が狭くなるため)。   First, as shown to (1) of the figure, the operator 34 attaches the cylinder 4 to the one suspension bolt 2 from the scaffold 33 for ceilings. This is because when the suspension bolt 2 is inserted into the insertion hole 14 of the cylindrical body 4 and the cylindrical body 4 is pushed up along the suspension bolt 2, the gripping material 16 is lowered and the insertion portion 19 is expanded. Pushed up. And when it pushes up until it reaches the uppermost part of the suspension bolt 2, that is, the slab lower surface 32, the cylindrical body 4 cannot be lowered by the gripping material 16 (because the gripping member 16 is contracted by the downward pressing force and the insertion portion 19 is narrowed). .

次に、同図の(2)に示すように、筒体4が挿入された吊りボルト2のXY方向に隣接する吊りボルト9に固定片8を取り付ける。これは斜め振止め材3の他端部に取り付けられていたのを取り外してから吊りボルト9に差し込むものである、そして、4本の斜め振止め材3を傘のように開いて、他端部を前記固定片8に接続する。これは図2に示すように、長ボルトである斜め振止め材3を固定片8のナット10にねじ込み、長さ調整を斜め振止め材3の回転で行う。   Next, as shown in (2) of the figure, the fixing piece 8 is attached to the suspension bolt 9 adjacent in the XY direction of the suspension bolt 2 in which the cylinder 4 is inserted. This is the one that is attached to the suspension bolt 9 after removing the other attached to the other end of the diagonal anti-vibration material 3, and the four other anti-vibration materials 3 are opened like an umbrella and the other end The part is connected to the fixed piece 8. As shown in FIG. 2, the diagonal anti-vibration material 3, which is a long bolt, is screwed into the nut 10 of the fixed piece 8, and the length is adjusted by the rotation of the diagonal anti-vibration material 3.

次に、同図の(3)に示すように、斜め振止め材3の下端部、すなわち固定片8が取り付けられた箇所に水平振止め材35を縦横方向に取り付けると、この水平振止め材35は、図7に示すように、筒体4が挿入された吊りボルト2を中心に十字形に取り付けられる。なお、第2および第3の実施の形態の振止め具21、22も同じ方法で取り付けるものとする。   Next, as shown in (3) of the figure, when the horizontal anti-vibration material 35 is attached in the vertical and horizontal directions to the lower end of the oblique anti-vibration material 3, that is, the place where the fixed piece 8 is attached, this horizontal anti-vibration material As shown in FIG. 7, 35 is attached in a cross shape around the suspension bolt 2 into which the cylindrical body 4 is inserted. It should be noted that the cleats 21 and 22 of the second and third embodiments are also attached by the same method.
