Description

本発明は、建物に壁材を取り付ける作業に好適な壁材の取付用治具と、これを用いた壁材の施工方法に関する。   The present invention relates to a wall material mounting jig suitable for a work of mounting a wall material on a building, and a wall material construction method using the same.

一般に、工場や倉庫などの鉄骨建築物では、胴縁の外側から波型などに形成された金属製の壁材（サイディングともいう。）を取り付けて外装がなされている。   In general, steel buildings such as factories and warehouses have a metal wall material (also referred to as siding) formed in a corrugated shape from the outside of the torso to provide an exterior.

こうした壁材を現場で取り付ける際は、まず、胴縁の外側に壁材の高さに合わせて複数段の足場を水平方向に延設する。そして、クレーンを用いて建築物の屋根の上や専用のラックなどに仮置した壁材を、１枚ずつロープを用いて人力で吊り下げたり、クレーンを用いるなどして胴縁と足場の間に降ろし、その吊るされた壁材の４隅を４人でそれぞれ持ちながら、胴縁に対する位置合わせを行った後、壁材を胴縁にビス止めしていく方法がとられている（例えば、特許文献１参照。）。   When mounting such a wall material on site, first, a multi-stage scaffolding is extended in the horizontal direction on the outside of the torso according to the height of the wall material. And, the wall material temporarily placed on the roof of the building using a crane or on a dedicated rack, etc. is manually suspended using a rope one by one or between the trunk edge and the scaffolding using a crane. It is a method in which the wall material is screwed to the trunk edge after being aligned to the trunk edge while holding the four corners of the suspended wall material by four persons respectively (for example, (See Patent Document 1).

このように壁材の取付作業を４人で行うのは、壁材の上下方向の長さが例えば６〜８ｍと長い場合に、左右から支持するだけでは、壁材の位置合わせが難しく、上下の足場に２名ずつ分かれて四方から壁材を支持する必要があるためである。   As described above, when the wall material is attached by four people, it is difficult to align the wall material by simply supporting it from the left and right when the vertical length of the wall material is as long as 6 to 8 m. This is because it is necessary to support the wall material from all sides by dividing two people into the scaffolding.

特開２００７−１１３２８２号公報JP 2007-113282 A

しかしながら、このように４人がかりで行う壁材の位置合わせは、４人の呼吸を合わせる必要があり、人手がかかる上に作業効率が低いものとなっている。また、上下の複数段の足場を使って行う作業は、上段からの落下物が下段の作業者に当たる危険がある。   However, the positioning of the wall material performed by four persons in this way requires the four persons to breathe together, which is labor intensive and has low work efficiency. In addition, when performing work using a plurality of upper and lower scaffolds, there is a risk that falling objects from the upper stage will hit the lower workers.

本発明の課題は、壁材の取り付け作業の安全性を高めるとともに、少ない人手で高い作業効率が得られるようにすることにある。   An object of the present invention is to increase the safety of wall work attachment work and to obtain high work efficiency with a small number of hands.

上記課題を解決するため、本発明は、建物の胴縁に壁材を取り付けるときに用いる壁材の取付用治具において、壁材の上端に引っ掛ける折り返し部を有して吊り下げられ、折り返し部の折り返し方向と反対方向にボルトの先を突出させるボルト穴が形成された吊り金具と、壁材に吊り下げられた状態の吊り金具にボルト及びナットで固定される板状部材とを備え、板状部材は、平板の両側部が互いに反対方向に折り曲げられ、この折り曲げ部のうち一方の折り曲げ部はボルトが挿通するボルト穴が形成され、他方の折り曲げ部を上向きにして使用されることを特徴とする。   In order to solve the above-described problems, the present invention provides a wall material mounting jig used when mounting a wall material on a body edge of a building, and has a folded part that is hooked on the upper end of the wall material, A suspension fitting in which a bolt hole is formed to project the tip of the bolt in a direction opposite to the folding direction, and a plate-like member fixed to the suspension fitting in a state suspended from a wall member with a bolt and a nut. The flat member is formed by bending both sides of the flat plate in opposite directions, and one of the bent portions is formed with a bolt hole through which a bolt is inserted, and the other bent portion is used upward. And

本発明の取付用治具は、吊り金具と板状部材の一方の折り曲げ部（下向きの折り曲げ部）とを当接させた状態でボルトを締め付け、既に胴縁に取り付けられた壁材（下壁材）の上端から吊り下げて使用され、下壁材の上方の他の壁材（上壁材）を取り付ける際に、上壁材の下端を板状部材で支持するものである。すなわち、吊り金具と板状部材の他方の折り曲げ部（上向きの折り曲げ部）との間には上壁材の下端を受ける受け面が形成され、その受け面に上壁材の下端が当接することで、上壁材を下から支持することができる。しかも、受け面は、吊り金具と上向きの折り曲げ部との間に形成されるため、上壁材が脱落しにくい。   The mounting jig of the present invention is a wall material (lower wall) that is already attached to the trunk edge by tightening the bolt in a state in which the hanging metal fitting and one bent portion (downward bent portion) of the plate-like member are in contact with each other. When the other wall member (upper wall member) above the lower wall member is attached, the lower end of the upper wall member is supported by a plate-like member. That is, a receiving surface for receiving the lower end of the upper wall material is formed between the hanging metal fitting and the other bent portion (upward bent portion) of the plate-like member, and the lower end of the upper wall material is in contact with the receiving surface. Thus, the upper wall material can be supported from below. Moreover, since the receiving surface is formed between the hanging metal fitting and the upward bent portion, the upper wall material is difficult to drop off.

したがって、上壁材を胴縁に取り付ける際は、例えば、下壁材の上端に複数の取付用治具を吊り下げ、上壁材の下端側をこれらの取付用治具の上に載せた状態で上端側を胴縁に取り付けた後、取付用治具を下壁材から取り外してから、上壁材の下端側を胴縁に取り付ける。このようにすれば、上壁材の上端側と下端側を順番に取り付ければよいため、少ない人手で作業することが可能となり、しかも落下物からの危険を回避することができる。また、取付用治具は、水平に延在する下壁材の上端に吊り下げられるため、その取付用治具に支持される上壁材は水平に配置される。このため、取付用治具を用いれば、上壁材の水平調整を高い精度で容易に行うことができる。ここで、取付用治具を下壁材から取り外すときは、ナットを緩め、吊り金具と板状部材の下向きの折り曲げ部との間に隙間を作り、その隙間に上壁材の下端部が位置するようにして持ち上げることで、簡単に取り外すことができる。   Therefore, when attaching the upper wall material to the body edge, for example, a state in which a plurality of mounting jigs are hung on the upper end of the lower wall material and the lower end side of the upper wall material is placed on these mounting jigs After attaching the upper end side to the trunk edge, remove the mounting jig from the lower wall material, and then attach the lower end side of the upper wall material to the trunk edge. If it does in this way, since it only has to attach the upper end side and lower end side of an upper wall material in order, it becomes possible to work with few manpower, and the danger from a fallen object can be avoided. Further, since the mounting jig is suspended from the upper end of the lower wall material extending horizontally, the upper wall material supported by the mounting jig is horizontally disposed. For this reason, if the mounting jig is used, the horizontal adjustment of the upper wall material can be easily performed with high accuracy. Here, when removing the mounting jig from the lower wall material, loosen the nut, create a gap between the hanging bracket and the downward bent part of the plate-like member, and the lower end of the upper wall material is located in the gap It can be easily removed by lifting it up.

具体的に、本発明の取付用治具を用いた壁材の施工方法は、建物の胴縁に取り付けられた壁材の上端に取付用治具を吊り下げる工程と、壁材と異なる他の壁材の下端を壁材に吊り下げられた取付用治具の板状部材の上に載せた状態で前記他の壁材の上端側を前記胴縁に取り付ける工程と、取付用治具のボルトを緩めて吊り金具と板状部材との間に隙間を形成し、この隙間に他の壁材の下端が位置するように取付用治具を持ち上げることで壁材から取付用治具を取り外す工程と、他の壁材の下端側を前記胴縁に取り付ける工程と、を含むものである。   Specifically, the wall material construction method using the mounting jig of the present invention includes a step of suspending the mounting jig on the upper end of the wall material attached to the body edge of the building, and other different from the wall material. Attaching the upper end side of the other wall material to the trunk edge in a state where the lower end of the wall material is placed on the plate-like member of the mounting jig suspended from the wall material, and a bolt of the mounting jig The step of removing the mounting jig from the wall material by loosening and forming a gap between the hanging bracket and the plate-like member and lifting the mounting jig so that the lower end of the other wall material is located in this gap And a step of attaching the lower end side of the other wall material to the trunk edge.

ところで、近年では、作業用の足場を機械的に昇降させる昇降装置が普及しており、このような昇降装置を壁材の取り付け作業に導入すれば、仮設の足場を設ける必要がなくなり、工期短縮やコスト削減などが期待できる。しかし、この種の昇降装置は、通常１段の足場を昇降させる構造のため、壁材の取り付け作業に使用するには、少なくとも高さの異なる２段の足場を昇降させる必要がある。その場合、昇降装置の積載重量の制限をクリアするためには、各段の足場の水平方向の長さを短縮して軽量化しなければならず、結果として作業範囲が狭くなり、作業効率の低下を招くことになる。   By the way, in recent years, lifting devices that mechanically raise and lower work scaffolds have become widespread, and if such lifting devices are introduced into the work of attaching wall materials, there is no need to provide temporary scaffolds and the construction period can be shortened. And cost reductions can be expected. However, since this type of lifting device usually has a structure that raises and lowers a one-stage scaffold, it is necessary to raise and lower at least two-stage scaffolds having different heights in order to be used for wall mounting work. In that case, in order to clear the limit on the loading weight of the lifting device, the horizontal length of the scaffolding at each stage must be shortened to reduce the weight, resulting in a narrow working range and reduced working efficiency. Will be invited.

これに対し、本発明の取付用治具を用いれば、１段の足場を昇降させる周知の昇降装置を用いて壁材の取付作業が可能になる。このため、取付用治具を用いた壁材の施工の際に、その昇降装置によって胴縁に取り付ける壁材を搬送するようにすれば、仮設の足場を設ける施工費用を削減できることに加えて、屋根の上から壁材をロープで吊り下げたり、クレーンで壁材を吊り下げる必要がなくなるため、壁材の取付作業の安全性と作業効率を高めることができる。   On the other hand, when the mounting jig of the present invention is used, the wall material can be mounted using a known lifting device that lifts and lowers the one-step scaffold. For this reason, in the construction of the wall material using the mounting jig, if the wall material attached to the trunk edge is transported by the lifting device, in addition to reducing the construction cost of providing a temporary scaffold, Since it is not necessary to suspend the wall material with a rope from the top of the roof or to suspend the wall material with a crane, the safety and work efficiency of the wall material mounting work can be improved.

本発明によれば、壁材の取り付け作業の安全性を高めるとともに、少ない人手で高い作業効率を得ることができる。   ADVANTAGE OF THE INVENTION According to this invention, while improving the safety | security of the attachment operation | work of a wall material, high work efficiency can be obtained with few manual labor.

以下、本発明の取付用治具と取付用治具を用いた壁材の施工方法の実施形態について、図面を参照して具体的に説明する。   Hereinafter, an embodiment of a mounting method and a wall material construction method using the mounting jig of the present invention will be specifically described with reference to the drawings.

図４に示すように、工場や倉庫などでは、鉄骨建築物の骨組を外側から塞いで外装する壁材として、サイディング１が使用される。このサイディング１には、軽量、美観、耐久性及びコストの点で優れた汎用材として、金属製の板材を波型に加工したものが使用される。   As shown in FIG. 4, a siding 1 is used in a factory, a warehouse, or the like as a wall material that closes a framework of a steel frame from the outside. As the siding 1, a metal plate material processed into a corrugated shape is used as a general-purpose material excellent in terms of light weight, aesthetics, durability, and cost.

鉄骨建築物の骨組は、例えばＨ型鋼による本柱（図示せず）が所定の間隔でコンクリート基礎の上に立ち上げられ、その本柱間に渡ってサイディング１の高さに合わせて複数段の胴縁３が取り付けられて構成される。こうした鉄骨建築物の骨組に外側からサイディング１が１枚ずつ縦継ぎ及び横継ぎして外装される。   The framework of a steel building is composed of, for example, main pillars (not shown) made of, for example, H-shaped steel, which are set up on a concrete foundation at a predetermined interval. The trunk edge 3 is attached and configured. A siding 1 is longitudinally and laterally attached to the frame of such a steel building from the outside one by one.

胴縁３の所定位置に位置決めされたサイディング１は、例えば、胴縁３に押し付けられた状態でキリによって下穴が空けられ、ドリルビスが締め込まれることで胴縁３に固定される。サイディング１の大きさは、建物の形状や大きさなどに合わせて、適当な大きさに切り揃えられたものが使用されるが、ここでは、上下方向の長さが、例えば６〜８ｍのものを使用するものとする。   The siding 1 positioned at a predetermined position of the trunk edge 3 is fixed to the trunk edge 3 by drilling a pilot hole with a drill while being pressed against the trunk edge 3 and tightening a drill screw, for example. The size of the siding 1 is adjusted to an appropriate size according to the shape and size of the building. Here, the vertical length is, for example, 6 to 8 m. Shall be used.

次に、本発明の特徴部となる取付用治具の構成について図１を参照して説明する。取付用治具５は、サイディング１を胴縁３に取り付ける際に使用されるものであり、サイディング１を縦継ぎする際に好適な道具である。   Next, the configuration of the mounting jig that is a feature of the present invention will be described with reference to FIG. The attachment jig 5 is used when attaching the siding 1 to the trunk edge 3 and is a suitable tool for longitudinally connecting the siding 1.

本実施形態の取付用治具５は、吊り金具７と板状部材９を備えて構成され、吊り金具７と板状部材９が、ボルト１１及びナット１３によって互いに固定された状態で使用される。吊り金具７は、２本の長尺の板材１５からなり、各板材１５には、一端側を他端側に折り返した折り返し部１７が設けられ、他端側には板材１５と直交する方向に貫通する図示しないボルト穴が形成されている。なお、吊り金具７は、板材に限らず、棒材であってもよい。   The mounting jig 5 according to the present embodiment is configured to include a suspension fitting 7 and a plate-like member 9, and is used in a state where the suspension fitting 7 and the plate-like member 9 are fixed to each other by a bolt 11 and a nut 13. . The hanging metal fitting 7 is composed of two long plate members 15, and each plate member 15 is provided with a folded portion 17 that is folded at one end side to the other end side, and in the direction orthogonal to the plate member 15 at the other end side. A bolt hole (not shown) that penetrates is formed. The hanging metal fitting 7 is not limited to a plate material but may be a bar material.

板状部材９は、略矩形の平板を互いに平行な２本の折り曲げ線１９、２１に沿って反対方向に略直角に折り曲げて形成される。すなわち、板状部材９は、折り曲げ線１９、２１に挟まれた受け面２３と、その受け面２３を折り曲げ線１９に沿って折り曲げて形成される折り曲げ面２５と、その受け面２３を折り曲げ線２１に沿って折り曲げて形成される折り曲げ面２７とから構成される。折り曲げ面２５の２箇所には、その折り曲げ面２５と直交する方向に貫通する図示しないボルト穴が形成されている。   The plate-like member 9 is formed by bending a substantially rectangular flat plate along two fold lines 19 and 21 parallel to each other in the opposite direction at a substantially right angle. That is, the plate-like member 9 includes a receiving surface 23 sandwiched between the folding lines 19, 21, a bending surface 25 formed by bending the receiving surface 23 along the folding line 19, and the receiving surface 23 as a folding line. And a bent surface 27 formed by being bent along the line 21. Bolt holes (not shown) penetrating in a direction orthogonal to the bending surface 25 are formed at two places on the bending surface 25.

図１に示すように、吊り金具７と板状部材９は、吊り金具７側からボルト穴にボルト１１が挿入され、板状部材９（折り曲げ面２５）のボルト穴から出たボルト１１にナット１３が締め付けられることで互いに固定される。ボルト１１とナット１３が完全に締め付けられることで、板状部材９は、折り曲げ面２５が、吊り金具７に当接した状態で固定される。このとき、吊り金具７は、折り返し部１７が板状部材９と反対方向に折り返されて配置され、板状部材９は、折り曲げ面２７が吊り金具７の長手方向と略平行、かつ吊り金具７の折り返し部１７が位置する方向（図１の上方）に向けて、受け面２３から折り曲げられた状態で配置されている。   As shown in FIG. 1, the suspension fitting 7 and the plate-like member 9 are configured such that the bolt 11 is inserted into the bolt hole from the suspension fitting 7 side, and the nut 11 is attached to the bolt 11 protruding from the bolt hole of the plate-like member 9 (bending surface 25). 13 are fastened to each other by being tightened. When the bolt 11 and the nut 13 are completely tightened, the plate-like member 9 is fixed in a state where the bent surface 25 is in contact with the suspension fitting 7. At this time, the suspension fitting 7 is arranged with the folded portion 17 folded back in the direction opposite to the plate-like member 9, and the plate-like member 9 has the bent surface 27 substantially parallel to the longitudinal direction of the suspension fitting 7 and the suspension fitting 7. Are arranged in a state of being bent from the receiving surface 23 in a direction (upward in FIG. 1) in which the folded portion 17 is located.

このように取付用治具５は、吊り金具７と板状部材９がボルト１１及びナット１３で互いに締結された状態で一つの部品をなしているが、吊り金具７と板状部材９は、ボルト１１及びナット１３が取り外され、ばらばらの状態でサイディングの取付現場（足場）まで運ばれ、必要に応じて組み立てて使用される。   As described above, the mounting jig 5 is a single component in a state in which the suspension fitting 7 and the plate-like member 9 are fastened to each other by the bolt 11 and the nut 13. The bolts 11 and the nuts 13 are removed, and are transported to a siding installation site (scaffold) in a separated state, and assembled and used as necessary.

次に、このようにして構成される取付用治具５を用いて、サイディングを胴縁３に取り付ける作業の手順について、図２及び図３を用いて説明する。   Next, the procedure for attaching the siding to the trunk edge 3 using the attachment jig 5 configured as described above will be described with reference to FIGS.

まず、図２（ａ）に示すように、取付用治具５の吊り金具７をサイディング１の上端に取り付ける。ここで、吊り金具７は、折り返し部１７をサイディング１の上端に引っ掛けることで、サイディング１の上端から吊り下げられる。吊り金具７は、所定の間隔を開けてサイディング１の上端の複数箇所（図２では２箇所）に取り付けられる。それぞれの吊り金具７のボルト穴には、サイディング１を背にしてボルト１１が挿通され、そのボルト１１が手前側、つまり吊り金具７の折り返し部１７の折り返し方向と反対方向に突出した状態となる。   First, as shown in FIG. 2A, the hanging bracket 7 of the mounting jig 5 is attached to the upper end of the siding 1. Here, the suspension fitting 7 is suspended from the upper end of the siding 1 by hooking the folded portion 17 on the upper end of the siding 1. The suspension fittings 7 are attached to a plurality of locations (two locations in FIG. 2) at the upper end of the siding 1 with a predetermined interval. Bolts 11 are inserted into the bolt holes of the respective hanging brackets 7 with the siding 1 as the back, and the bolts 11 protrude in the front side, that is, in a direction opposite to the folding direction of the folded portion 17 of the hanging bracket 7. .

次に、図２（ｂ）に示すように、板状部材９を、折り曲げ面２７が上向きになるように、ボルト１１、ナット１３を介して２つの吊り金具７に固定する。ボルト１１及びナット１３は、吊り金具７と折り曲げ面２５が当接するまで締め付けられる。   Next, as shown in FIG. 2B, the plate-like member 9 is fixed to the two suspension fittings 7 via the bolts 11 and the nuts 13 so that the bent surface 27 faces upward. The bolt 11 and the nut 13 are tightened until the hanger 7 and the bent surface 25 abut.

次に、図２（ｃ）に示すように、サイディング１の上に取り付ける他のサイディング３１の下端を取付用治具５の受け面２３の上に仮置きし、他のサイディング３１を下から支持した状態で、他のサイディング３１の上端側を胴縁に固定する。ここで、サイディング３１は、何らかの理由で下端が吊り金具７から離れる方向に動くことも考えられるが、サイディング３１の動く方向には折り曲げ面２７が立ち上がって形成されるため、サイディング３１が取付用治具５から脱落するのを阻止することができる。   Next, as shown in FIG. 2 (c), the lower end of another siding 31 to be mounted on the siding 1 is temporarily placed on the receiving surface 23 of the mounting jig 5, and the other siding 31 is supported from below. In this state, the upper end side of the other siding 31 is fixed to the trunk edge. Here, the siding 31 may move in a direction in which the lower end moves away from the hanging bracket 7 for some reason. However, since the siding 31 is formed with the bent surface 27 rising in the moving direction of the siding 31, the siding 31 is attached. It is possible to prevent the tool 5 from falling off.

続いて、他のサイディング３１の下端側を胴縁に固定するため、取付用治具５をサイディング１の上端から取り外す。ここで、取付用治具５をサイディング１から取り外す手順について、図３の断面図を用いて説明する。   Subsequently, the mounting jig 5 is removed from the upper end of the siding 1 in order to fix the lower end side of the other siding 31 to the trunk edge. Here, the procedure for removing the mounting jig 5 from the siding 1 will be described with reference to the cross-sectional view of FIG.

図３（ａ）に示すように、サイディング１から吊り下げられた取付用治具５の受け面２３には、他のサイディング３１の下端が当接している。   As shown in FIG. 3A, the lower end of another siding 31 is in contact with the receiving surface 23 of the mounting jig 5 suspended from the siding 1.

この状態で、図３（ｂ）に示すように、ナット１３を緩め、吊り金具７と板状部材９の折り曲げ面２５との間に隙間３３を作り、その隙間３３に他のサイディング３１の下端部を位置させるようにして、取付用治具５を持ち上げていく。このとき、他のサイディング３１は上端側が胴縁に固定されているため、下端が隙間３３に位置して受け面２３から支持されなくなっても、落下することがない。このように他のサイディング３１の下端が隙間３３に位置するようにすれば、取付用治具５を容易に持ち上げることができる。取付用治具５が持ち上げられると、サイディング１の上端から吊り金具７の折り返し部１７が離脱するため、取付用治具５はサイディング１から分離される。   In this state, as shown in FIG. 3 (b), the nut 13 is loosened to create a gap 33 between the suspension fitting 7 and the bent surface 25 of the plate-like member 9, and the lower end of the other siding 31 is formed in the gap 33. The mounting jig 5 is lifted so that the part is positioned. At this time, since the upper end side of the other siding 31 is fixed to the trunk edge, even if the lower end is located in the gap 33 and is not supported from the receiving surface 23, it does not fall. If the lower end of the other siding 31 is positioned in the gap 33 in this way, the mounting jig 5 can be easily lifted. When the mounting jig 5 is lifted, the folded portion 17 of the hanging bracket 7 is detached from the upper end of the siding 1, so that the mounting jig 5 is separated from the siding 1.

次に、図３（ｃ）に示すように、吊り金具７の折り返し部１７がサイディング１の上端から離脱した取付用治具５を、サイディング１と他のサイディング３１との間に吊り金具７を通して下方に引き出す。   Next, as shown in FIG. 3C, the mounting jig 5 in which the folded portion 17 of the hanging bracket 7 is detached from the upper end of the siding 1 is passed through the hanging bracket 7 between the siding 1 and the other siding 31. Pull it down.

そして、図３（ｄ）に示すように、取付用治具５が抜き出された後、他のサイディング３１の下端は、サイディング１の上端と重なるようにして胴縁に固定される。   Then, as shown in FIG. 3D, after the mounting jig 5 is extracted, the lower ends of the other sidings 31 are fixed to the trunk edge so as to overlap the upper ends of the sidings 1.

このように取付用治具５をサイディング１から取り外すことができるのは、取付用治具５の隙間３３に他のサイディング３１の下端を位置させた状態で取付用治具５を持ち上げたとき、他のサイディング３１の下端がボルト１１に当接する前に、サイディング１の上端から吊り金具７の折り返し部１７が離脱するためである。すなわち、取付用治具５は、図１に示すように、折り曲げ面２５の折り曲げ線１９からボルト穴の縁までの距離Ａが、折り返し部１７の内周側の折り返し長さＢよりも長く設定されている。   The mounting jig 5 can be removed from the siding 1 in this manner when the mounting jig 5 is lifted with the lower end of the other siding 31 positioned in the gap 33 of the mounting jig 5. This is because the folded portion 17 of the hanging bracket 7 is detached from the upper end of the siding 1 before the lower end of the other siding 31 comes into contact with the bolt 11. That is, as shown in FIG. 1, the mounting jig 5 is set such that the distance A from the folding line 19 of the folding surface 25 to the edge of the bolt hole is longer than the folding length B on the inner peripheral side of the folding portion 17.

次に、図４を参照して、取付用治具５を用いたサイディングの取付作業について、より具体的に説明する。   Next, with reference to FIG. 4, the siding attachment work using the attachment jig 5 will be described more specifically.

胴縁の外側には、作業用の足場を機械的に昇降させる図示しない昇降装置が配置され、足場の高さは、作業者の操作或いは地上からの遠隔操作によって自在に調整できるようになっている。昇降装置には１段だけの足場３５が設けられ、この足場３５を利用して、取付用治具５及び取付用のサイディングが上方に搬送される。なお、従来の仮設足場は設けられていないものとする。   A lifting device (not shown) that mechanically lifts and lowers the working scaffold is arranged outside the torso edge, and the height of the scaffold can be freely adjusted by the operator's operation or remote operation from the ground. Yes. The lifting device is provided with a single-stage scaffold 35, and using this scaffold 35, the mounting jig 5 and the mounting siding are conveyed upward. It is assumed that a conventional temporary scaffold is not provided.

まず、図４（ａ）に示すように、既に胴縁３に取り付けられたサイディング１の上端に、取付用治具５を吊り下げる。取付用治具５の取り付け方法は、図２で説明した通りである。なお、図４（ａ）では、作業者を省略している。   First, as shown in FIG. 4A, the attachment jig 5 is suspended from the upper end of the siding 1 already attached to the trunk edge 3. The attachment method of the attachment jig 5 is as described in FIG. In FIG. 4A, the worker is omitted.

次に、図４（ｂ）に示すように、足場３５の高さ位置を上方に移動させ、新たに取り付けるサイディング３１の上端側を２名の作業者がそれぞれ持ちながら、サイディング３１の下端を取付用治具５の上に仮置きする。   Next, as shown in FIG. 4 (b), the height position of the scaffold 35 is moved upward, and two workers hold the upper end side of the newly installed siding 31, and the lower end of the siding 31 is attached. Temporarily placed on the jig 5.

そして、図４（ｃ）に示すように、２名の作業者がサイディング３１の上端側を持つことで、胴縁３に対してサイディング３１の位置出しを行った後、サイディング３１の上端側の左右をそれぞれ胴縁３に固定する。   Then, as shown in FIG. 4 (c), two workers hold the upper end side of the siding 31, and after positioning the siding 31 with respect to the trunk edge 3, The left and right sides are fixed to the trunk edge 3.

続いて、図４（ｄ）に示すように、足場３５の高さ位置を下方に移動させ、取付用治具５を取り外した後、サイディング３１の下端側の左右をそれぞれ胴縁３に固定する。   Subsequently, as shown in FIG. 4 (d), the height position of the scaffold 35 is moved downward, the attachment jig 5 is removed, and then the left and right sides of the lower end side of the siding 31 are fixed to the trunk edge 3. .

このように、取付用治具５は、水平に設置されたサイディング１の上端に吊り下げられるため、その取付用治具５に支持されるサイディング３１は水平に配置される。このため、取付用治具５を用いれば、サイディング３１の水平調整を高い精度で容易に行うことができる。また、取付用治具５を用いれば、サイディング３１の上端側と下端側を胴縁３に順番に取り付けることができるため、サイディング３１を胴縁３に取り付ける作業のすべてを、例えば、２名の作業員が１段の足場だけで行うことができる。したがって、作業者の数を例えば半分に減らすことができ、しかも、上段側からの落下物の危険を回避できるため、作業の安全性を向上することができる。   In this manner, the mounting jig 5 is suspended from the upper end of the horizontally installed siding 1, so that the siding 31 supported by the mounting jig 5 is disposed horizontally. For this reason, if the mounting jig 5 is used, the horizontal adjustment of the siding 31 can be easily performed with high accuracy. Further, if the mounting jig 5 is used, the upper end side and the lower end side of the siding 31 can be attached to the trunk edge 3 in order, so that all the operations for attaching the siding 31 to the trunk edge 3 can be performed by, for example, two people. It can be performed by a worker with only one stage of scaffolding. Therefore, the number of workers can be reduced to, for example, half, and the danger of falling objects from the upper side can be avoided, so that the safety of work can be improved.

また、取付用治具５を用いれば、１段の足場を昇降させる周知の昇降装置をサイディングの取付作業に導入することができる。その結果、従来のように仮設の足場を設ける必要がなくなるため、施工費用の削減が可能になる。また、サイディングを昇降装置で搬送するようにすれば、従来のように、屋根や専用のラックなどに仮置きしたサイディングをロープなどで吊り下げたり、クレーンで吊り下げて作業する必要がなくなるため、作業の安全性及び効率を高めることができる。   In addition, when the mounting jig 5 is used, a known lifting device that lifts and lowers the one-stage scaffold can be introduced into the siding mounting work. As a result, it is not necessary to provide a temporary scaffold as in the prior art, and construction costs can be reduced. Also, if the siding is transported with a lifting device, it is not necessary to hang the siding temporarily placed on the roof or a dedicated rack with a rope or work with a crane, as in the past, Work safety and efficiency can be increased.

以上、本発明の実施形態を図面により詳述してきたが、上記実施形態は本発明の例示にしか過ぎないものであり、本発明は上記実施形態の構成にのみ限定されるものではない。本発明の要旨を逸脱しない範囲の設計の変更などがあっても、本発明に含まれることは勿論である。   As mentioned above, although embodiment of this invention has been explained in full detail with drawing, the said embodiment is only an illustration of this invention and this invention is not limited only to the structure of the said embodiment. Needless to say, even if there is a design change within a range not departing from the gist of the present invention, it is included in the present invention.

例えば、取付用治具５は、吊り金具７をサイディングの上端から吊り下げた状態で、板状部材９をボルト１１及びナット１３で締め付け、取り付ける例を説明したが、予め、吊り金具７と板状部材９がボルト１１及びナット１３で固定されている状態で、サイディングの上端に吊り下げるようにしても構わない。   For example, in the mounting jig 5, the example in which the plate member 9 is fastened with the bolt 11 and the nut 13 in the state where the hanging bracket 7 is suspended from the upper end of the siding has been described. The siding member 9 may be suspended from the upper end of the siding while being fixed by the bolt 11 and the nut 13.

また、取付用治具５は、受け面２３に対して折り曲げ面２７を略直角に折り曲げて形成する例を説明したが、受け面２３に当接するサイディングが受け面２３から脱落しない程度の角度範囲であれば、この角度に限定されるものではない。   Further, although the example in which the mounting jig 5 is formed by bending the bending surface 27 at a substantially right angle with respect to the receiving surface 23 has been described, the angular range is such that the siding that contacts the receiving surface 23 does not fall off the receiving surface 23. If it is, it is not limited to this angle.

また、作業者の足場を確保する方法として、１段の足場を昇降させる昇降装置を用いる例を説明したが、この機能に加えて、例えば、地上に形成されるレールに沿って昇降装置を建物の幅方向で自在に移動させる機能を昇降装置に持たせることもできる。これによれば、仮設の足場を設ける必要がないというメリットを最大限に発揮することができ、しかも広範囲の作業領域を、より短時間で安全に施工することが可能となる。   Moreover, although the example which uses the raising / lowering apparatus which raises / lowers one step | paragraph scaffold was demonstrated as a method of ensuring a worker's scaffold, in addition to this function, for example, a raising / lowering apparatus is built along the rail formed on the ground. The elevating device can also have a function of moving freely in the width direction. According to this, the merit that it is not necessary to provide a temporary scaffold can be maximized, and a wide range of work areas can be safely constructed in a shorter time.

また、本実施形態では、金属製の波型に形成されたサイディングの取付作業を例に説明したが、これに限定されるものではなく、例えば、ＦＲＰやポリカーボネートなどの合成樹脂で形成されたサイディング、或いは、波型以外で形成されるサイディングについても、本発明の技術思想を有する取付用治具を用いれば、同様の効果を奏することができる。   Further, in the present embodiment, the siding attachment work formed in a metal corrugation has been described as an example. However, the present invention is not limited to this. For example, the siding formed of a synthetic resin such as FRP or polycarbonate is not limited thereto. Alternatively, a siding formed other than a corrugated shape can achieve the same effect by using a mounting jig having the technical idea of the present invention.
