本考案は、建築物と、これの外側に仮設される外部足場との取付構造に関し、 とりわけ、外部足場の取付枠を連結部材を介して建築物に予め設けたアンカーボ ルトに着脱可能に固定する建築物と外部足場との取付構造に関する。 The present invention relates to a mounting structure for a building and an external scaffold temporarily installed on the outside of the building. In particular, the mounting frame of the external scaffold is detachably fixed to an anchor bolt provided in the building through a connecting member. It relates to a mounting structure for a building and an external scaffold.
【０００２】[0002]
従来、建築物等の外壁工事を行うに、建築物外側に足場を仮設し、この足場上 で作業を行っているが、このように足場を組み立てるにあたって、高層建築物で は足場の組み立て作業が著しく困難になる。そこで、このような高層建築物では 、足場を競り上げまたは盛り替え等により順次上昇させていく方法が考えられ、 このような足場として、例えば、特公昭６３−３１６２９号公報に開示されたも のがある。 Conventionally, to perform outer wall construction of buildings, etc., a scaffold is temporarily installed on the outside of the building and work is performed on this scaffold.However, when assembling the scaffold in this way, scaffold assembly work is required for high-rise buildings. It becomes extremely difficult. Therefore, in such a high-rise building, a method of sequentially raising scaffolds by bidding or refilling is considered, and such scaffolds are disclosed, for example, in Japanese Examined Patent Publication No. 63-31629. There is.
【０００３】 即ち、かかる競り上げタイプの外部足場は、外壁の型枠を１ロットづつ上昇さ せるジャンピング工法に用いられ、足場フレームに対してこれを案内する相対移 動可能なレールを備える一方、壁面にはこれら足場フレームおよびレールをそれ ぞれ着脱可能に固定するアンカー金物を予め設けてある。そして、足場フレーム の競り上げは、一旦前記レールをアンカー金物から離脱してジャッキで１ロット 分だけ上昇した後、このレールを再度アンカー金物に固定し、次に、足場フレー ムをアンカー金物から離脱した後、前記レールに沿って足場フレームをジャッキ アップし、再度この足場フレームをアンカー金物に固定するようになっている。That is, such a bid-up type external scaffold is used in a jumping construction method in which the formwork of the outer wall is raised one lot at a time, and is provided with a rail capable of moving relative to the scaffolding frame, while Anchor hardware for detachably fixing the scaffolding frame and the rail is provided on the wall surface in advance. Then, when scaffolding the scaffolding frame, once the rail is detached from the anchor hardware and the jack is raised by one lot, the rail is fixed to the anchor hardware again, and then the scaffold frame is detached from the anchor hardware. After that, the scaffolding frame is jacked up along the rails, and the scaffolding frame is fixed to the anchor hardware again.
【０００４】 ところで、このように前記外部足場は、足場フレームおよびレールを順次上昇 する度に、これらをアンカー金物に着脱するようになっているが、この部分の取 付構造としては、例えば実公平２−１１５５２号公報に開示されたものがある。By the way, in the external scaffolding, the scaffolding frame and the rail are attached to and detached from the anchor metal fittings every time the scaffolding frame and the rail are sequentially raised. There is one disclosed in the Japanese Laid-Open Patent Publication No. 2-11552.
【０００５】 即ち、かかる従来の外部足場の取付構造としては、建築物に予めアンカー金物 を埋設しておく一方、外部足場に取付用の継手金具を水平方向に突設しておき、 これらアンカー金物と継手金具とを断面Ｌ字状の連結部材を介して結合するよう になっている。つまり、前記連結部材には一対の開口部を形成してあり、一方の 開口部に挿通したボルトを前記アンカー金物に締付けると共に、他方の開口部に 前記ねじ棒を挿通してナット止めすることにより、両者の結合が行われる。That is, as such a conventional mounting structure for an external scaffold, an anchor metal is embedded in a building in advance, while a fitting for mounting is horizontally projected on the external scaffold, and the anchor metal is installed. And the joint fitting are connected via a connecting member having an L-shaped cross section. That is, a pair of openings are formed in the connecting member, and the bolt inserted into one opening is tightened to the anchor metal object, and the screw rod is inserted into the other opening to fix the nut. , The two are combined.
【０００６】[0006]
しかしながら、かかる従来の建築物と外部足場との取付構造にあっては、連結 部材を介してアンカー金物と継手金物とを連結する際、この連結部材の開口部に 挿通したボルトおよびねじ棒を、前記アンカー金物およびナットに螺合するよう になっている。このため、外部足場を競り上げするにあたって、前記連結部材を 離脱するには、前記アンカー金物およびねじ棒からボルトおよびナットを完全に 取り外す必要があり、また、これとは逆に連結部材の取り付け時にはボルトおよ びナットを全てのねじ部に亘って完全に捩じ込む必要がある。従って、前記連結 部材の着脱作業が著しく困難となり、外部足場の競り上げ作業に大幅な時間を要 し、延いては、工期の長期化が余儀無くされてしまうという課題があった。 However, in such a conventional structure for attaching a building to an external scaffold, when connecting the anchor metal fitting and the joint metal fitting through the connecting member, the bolt and screw rod inserted through the opening of the connecting member are It is adapted to be screwed into the anchor metal and the nut. For this reason, when bidding on an external scaffold, it is necessary to completely remove the bolts and nuts from the anchor metal and the threaded rod in order to detach the connecting member, and conversely when attaching the connecting member. The bolts and nuts must be screwed in completely over all threads. Therefore, the work of attaching and detaching the connecting member becomes extremely difficult, and it takes a lot of time to bid up the external scaffolding, which inevitably lengthens the construction period.
【０００７】 そこで、本考案はかかる従来の課題に鑑みて、連結部材を取付用のねじ部に対 して軸直角方向に着脱可能とすることにより、ねじ部の完全な取り付けおよび取 り外しを必要とすることなく、足場の上昇作業を簡単かつ迅速に行うことができ る建築物と外部足場との取付構造を提供することを目的とする。In view of such conventional problems, the present invention allows the connecting member to be attached to and detached from the mounting screw portion in a direction perpendicular to the axis so that the screw portion can be completely attached and detached. It is an object of the present invention to provide a mounting structure for a building and an external scaffold that enables easy and quick scaffolding work without needing it.
【０００８】[0008]
かかる目的を達成するために本考案は、建築物の外側に仮設する外部足場の取 付枠を、連結部材を介して建築物に予め設けたアンカーボルトに着脱可能に固定 する建築物と外部足場との取付構造において、前記取付枠の幅方向両側に位置し て一対のアンカーボルトを建築物に植設し、連結部材の一端部に一方のアンカー ボルトを係止する第１切欠部を設けると共に、連結部材の他端部に他方のアンカ ーボルトを係止する第２切欠部を設け、第１切欠部は連結部材の一端に開放して この連結部材の長さ方向に所定長さ伸びる直線状に形成すると共に、第２切欠部 は連結部材の一側に開放してこの連結部材の幅方向に一旦伸び、その終端部が前 記第１切欠部に向かって伸びる略Ｌ字状に形成する。 In order to achieve such an object, the present invention provides a building and an external scaffolding in which an attachment frame of an external scaffolding temporarily installed on the outside of the building is detachably fixed to an anchor bolt provided in advance on the building through a connecting member. And a pair of anchor bolts, which are located on both sides of the mounting frame in the width direction, are planted in the building, and a first cutout portion for locking one anchor bolt is provided at one end of the connecting member. A second cutout portion for locking the other anchor bolt is provided at the other end of the connecting member, and the first cutout portion is open at one end of the connecting member and extends straight for a predetermined length in the length direction of the connecting member. The second notch is opened to one side of the connecting member and once extends in the width direction of the connecting member, and the terminal end thereof is formed in a substantially L shape extending toward the first notch. ..
【０００９】[0009]
以上の構成により本考案の建築物と外部足場との取付構造にあっては、まず外 部足場を建築物に取り付けるにあたって、この外部足場の取付枠を建築物に植設 した一対のアンカーボルト間に配置し、次に、連結部材の両端部に形成した第１ ，第２切欠部をこれら一対のアンカーボルトに挿通する。そして、前記連結部材 をアンカーボルトとの間で締め付けることにより、この連結部材と建築物との間 に前記取付枠を固定することができる。 According to the structure for mounting the building and the external scaffold of the present invention having the above-described structure, first, when mounting the outer scaffolding on the building, the mounting frame of the outer scaffold is installed between the pair of anchor bolts. Then, the first and second notches formed at both ends of the connecting member are inserted into the pair of anchor bolts. Then, by tightening the connecting member with the anchor bolt, the attachment frame can be fixed between the connecting member and the building.
【００１０】 前記第１切欠部は連結部材の一端に開放してこの連結部材の長さ方向に所定長 さ伸びる直線状に形成すると共に、第２切欠部は連結部材の一側に開放してこの 連結部材の幅方向に一旦伸び、その終端部が前記第１切欠部に向かって伸びる略 Ｌ字状に形成してあるので、連結部材とアンカーボルトとの締め付けを弛めて連 結部材をアンカーボルトの軸直角方向に移動するのみで、第１，第２切欠部をア ンカーボルトから離脱させることができる。このため、連結部材の着脱にあたっ てアンカーボルトの締め付けを完全に解除する必要がないため、連結部材の着脱 作業が著しく簡単化される。The first notch is opened at one end of the connecting member to form a straight line extending a predetermined length in the length direction of the connecting member, and the second notch is opened to one side of the connecting member. Since the connecting member is formed in a substantially L-shape that extends once in the width direction and extends toward the first cutout, the connecting member is loosened by tightening the connecting member and the anchor bolt. The first and second notches can be separated from the anchor bolt only by moving the anchor bolt in the direction perpendicular to the axis. Therefore, it is not necessary to completely release the tightening of the anchor bolts when attaching and detaching the connecting member, so that the attaching and detaching work of the connecting member is significantly simplified.

【００１７】 以上の構成により本実施例の建築物と外部足場１０との取付構造にあっては、 まず、図２に示したようにクレーンで縦枠１２および横枠１４からなる骨格Ｂを 所定高さまで吊り上げ、各横枠１４を建築物１８の床面２０に植設したアンカー ボルト２８，２８に、前記アングルピース２２，ワッシャー３４，３４およびナ ット３６，３６を介して固定する。尚、前記横枠１４の固定状態を、図３の平面 図によってナット３６，３６部分から切断して示す。In the mounting structure of the building and the external scaffolding 10 of the present embodiment having the above-described configuration, first, as shown in FIG. 2, the skeleton B including the vertical frame 12 and the horizontal frame 14 is predetermined by the crane. The horizontal frames 14 are lifted to a height and fixed to the anchor bolts 28, 28 planted on the floor surface 20 of the building 18 via the angle pieces 22, washers 34, 34 and nuts 36, 36. The fixed state of the horizontal frame 14 is shown by cutting from the nuts 36, 36 in the plan view of FIG.
【００１８】 そして、前記横枠１４の固定状態で前記横枠１４の上側に足場板１６を載置し て取付けることにより、外部足場１０の固定が行われる。尚、前記外部足場１０ の縦枠１２は、図１中においては１本のみを示すが、実際には建築物１８の幅方 向（図１中紙面直角方向）に、複数本の縦枠１２が適宜間隔をもって互いに結合 した状態で設けられ、それぞれの縦枠１２に取付けた横枠１４間に前記足場板１ ６を掛け渡して支持される。Then, the outer scaffold 10 is fixed by mounting and mounting the scaffolding plate 16 on the upper side of the horizontal frame 14 in the fixed state of the horizontal frame 14. Although only one vertical frame 12 is shown in FIG. 1 in the external scaffolding 10, a plurality of vertical frames 12 are actually provided in the width direction of the building 18 (direction perpendicular to the plane of FIG. 1). Are provided in a state of being coupled to each other at appropriate intervals, and the scaffolding plates 16 are hung and supported between the horizontal frames 14 attached to the respective vertical frames 12.
【００１９】 次に、前記外部足場１０を盛り替えにより上昇する場合、まず、縦枠１２をク レーンで吊持した状態で各横枠１４のアングルピース２２を取り外し、この横枠 １４をアンカーボルト２８，２８から離脱させる。そして、前記縦枠１２および 横枠１４からなる骨格Ｂをクレーンにより縦枠１２の高さ分、つまり本実施例で は２階層分だけ上昇して、再度横枠１４の突出端部を床面２０にアンカーボルト ２８およびアングルピース２２等を介して固定する。尚、前記足場板１６を横枠 １４に確実に固定しておくことにより、外部足場１０の盛り替え時にこの足場板 １６をその都度取り外す必要がなくなる。Next, when the external scaffolding 10 is lifted by refilling, first, the angle pieces 22 of each horizontal frame 14 are removed while the vertical frame 12 is suspended by a crane, and the horizontal frame 14 is anchor bolt. 28, 28 is disengaged. Then, the skeleton B composed of the vertical frame 12 and the horizontal frame 14 is lifted by the crane by the height of the vertical frame 12, that is, two layers in this embodiment, and the projecting end of the horizontal frame 14 is again fixed to the floor surface. It is fixed to 20 via anchor bolts 28 and angle pieces 22. By securely fixing the scaffold plate 16 to the lateral frame 14, it is not necessary to remove the scaffold plate 16 each time the external scaffold 10 is refilled.
【００２０】 ところで、前記外部足場１０を盛り替えする際に、横枠１４を固定するアング ルプレート２２をアンカーボルト２８，２８からその都度着脱する必要があるが 、本実施例ではこのアングルプレート２２の両端部に第１，第２切欠部３０，３ ２を設けたので、アンカーボルト２８，２８への着脱を極簡単に行うことができ る。 即ち、前記アングルプレート２２をアンカーボルト２８，２８から離脱す る際には、まずナット３６，３６を弛めて、ワッシャー３４，３４を切欠状の挿 通穴３４ａ，３４ａを介してアンカーボルト２８，２８の横方向に取り外す。次 に、図４に示したようにアングルピース２２を、第１切欠部３０に係止したアン カーボルト２８を中心として図中時計回り方向（Ｘ）に回転し、他方のＬ字状の 第２切欠部３２をアンカーボルト２８から離脱させる。そして、図５に示したよ うに前記第１切欠部３０と、これに係止したアンカーボルト２８とが互いに離れ る方向（Ｙ）にアングルピース２２を水平移動することにより、このアングルピ ース２２をアンカーボルト２８，２８から取り外すことができる。By the way, when the external scaffold 10 is refilled, the angle plate 22 for fixing the lateral frame 14 needs to be detached from the anchor bolts 28, 28 each time, but in the present embodiment, the angle plate 22 is used. Since the first and second notches 30 and 32 are provided at both ends of the anchor, it is possible to attach and detach the anchor bolts 28 and 28 very easily. That is, when detaching the angle plate 22 from the anchor bolts 28, 28, first, the nuts 36, 36 are loosened, and the washers 34, 34 are inserted through the notch-shaped insertion holes 34a, 34a. , 28 laterally. Next, as shown in FIG. 4, the angle piece 22 is rotated in the clockwise direction (X) in the drawing around the anchor bolt 28 locked in the first cutout portion 30, and the other L-shaped second piece is rotated. The notch 32 is detached from the anchor bolt 28. Then, as shown in FIG. 5, the angle piece 22 is moved horizontally by horizontally moving the angle piece 22 in a direction (Y) in which the first notch portion 30 and the anchor bolt 28 locked to the first notch portion 30 are separated from each other. It can be removed from the anchor bolts 28, 28.
【００２１】 一方、アングルピース２２のアンカーボルト２８，２８への取り付けは、前記 取り外しのときとは逆の操作を行い、まず、第１切欠部３０を一方のアンカーボ ルト２８に横方向から係止し、次に、このアンカーボルト２８を中心にアングル ピース２２を反時計回り方向に回転して、第２切欠部３２に他方のアンカーボル ト２８を係止する。その後、ワッシャー３４，３４をアングルピース２２とナッ ト３６，３６との間に差し込んで、これらナット３６，３６を締め付ける。On the other hand, when attaching the angle piece 22 to the anchor bolts 28, 28, the reverse operation to the above-mentioned removal is performed, and first, the first cutout portion 30 is laterally locked to the one anchor bolt 28. Then, the angle piece 22 is rotated counterclockwise around the anchor bolt 28 to lock the other anchor bolt 28 in the second cutout portion 32. After that, the washers 34, 34 are inserted between the angle piece 22 and the nuts 36, 36, and the nuts 36, 36 are tightened.
【００２２】 従って、前記アングルピース２２をアンカーボルト３４，３４に着脱するには 、ナット３４，３４を単に弛めるのみで良く、つまり、ナット３４，３４をアン カーボルト２８，２８に取付けた状態で、アングルピース２２を横から着脱する ことができる。このため、前記アングルピース２２の着脱作業が大幅に簡単化さ れるため、前記外部足場１０の盛り替え作業が著しく簡単になる。Therefore, in order to attach / detach the angle piece 22 to / from the anchor bolts 34, 34, it is sufficient to simply loosen the nuts 34, 34, that is, with the nuts 34, 34 attached to the anchor bolts 28, 28, The angle piece 22 can be attached and detached from the side. Therefore, the work of attaching and detaching the angle piece 22 is significantly simplified, and the work of refilling the external scaffold 10 is significantly simplified.
【００２３】 尚、本実施例の取付構造は、縦枠１２，横枠１４で骨格Ｂを成す外部足場１０ に適用した場合を開示したが、これに限ることなく、他の構成が取られる外部足 場にあっても本考案を適用できることは勿論である。Although the mounting structure of the present embodiment is disclosed as being applied to the external scaffold 10 that forms the skeleton B with the vertical frame 12 and the horizontal frame 14, the invention is not limited to this, and an external structure having another structure can be adopted.

以上説明したように本考案の建築物の外部足場にあっては、外部足場の取付枠 を建築物のアンカーボルトに取り付ける際に、連結部材の両端部に直線状の第１ 切欠部と、Ｌ字状の第２切欠部とを形成して、これら第１，第２切欠部をアンカ ーボルトの軸直角方向に係止したので、連結部材とアンカーボルトとの締め付け を弛めて、連結部材をアンカーボルトの軸直角方向に移動するのみで、第１，第 ２切欠部をアンカーボルトに着脱することができる。従って、連結部材の着脱に あたってアンカーボルトの締め付けを完全に解除する必要がないため、連結部材 の着脱作業が著しく簡単化され、延いては、外部足場の上昇作業を簡単かつ迅速 に行い、工期の大幅な短縮を図ることができるという優れた効果を奏する。 As described above, in the external scaffolding of the present invention, when the mounting frame of the external scaffolding is attached to the anchor bolt of the building, the first linear cutouts and L-shaped notches are provided at both ends of the connecting member. Since the second notch having a character shape is formed and the first and second notches are locked in the direction perpendicular to the axis of the anchor bolt, the tightening of the connecting member and the anchor bolt is loosened, and the connecting member is removed. The first and second notches can be attached to and detached from the anchor bolt only by moving in the direction perpendicular to the axis of the anchor bolt. Therefore, it is not necessary to completely release the tightening of the anchor bolts when attaching / detaching the connecting member, so that the attaching / detaching work of the connecting member is significantly simplified, and as a result, the raising work of the external scaffold can be performed easily and quickly. It has an excellent effect that the construction period can be significantly shortened.
