Description

本発明は、屋根改修工事において、既設スレート屋根をそのままにするとともに、前記既設スレート屋根には穿孔又は切断等の加工による切粉の飛散をまったく抑えたり又はその飛散を極めて微々たるものとすることができ、しかも仮設足場,安全ネット張り等の段取施工を最小限として改修屋根の施工を簡易且つ迅速に行うことができる改修屋根及びその改修工法に関する。   In the present invention, in the roof renovation work, the existing slate roof is left as it is, and the existing slate roof is completely prevented from scattering of chips due to drilling or cutting, or the scattering is extremely small. Further, the present invention relates to a repair roof and a repair method for the repair roof that can be easily and quickly performed on a repair roof with minimal setup work such as temporary scaffolding and safety netting.

老朽化した既設スレート屋根を改修する工事において、その現場である工場,会社,駐車場等では、既設スレート屋根を撤去する時に粉塵等が立ち込めたり、また撤去作業では、取り外した屋根板材等の部品が落下したり、或は雨天の場合には設備、製品,自動車等に保護のためテント,天幕,カバー等の仮設家屋を設営しなければならないものであった。さらに、工事の規模や現場の状況によっては、会社、工場等の操業及び使用を一時,中断することもあり、その間に生じる物的,金銭的な損失,損害は極めて甚大である。このため、最近では改修屋根の葺成において、既設スレート屋根はなるべく、そのまま残して、該既設スレート屋根上に新たなる屋根を施工することが一般的となっている。
特開平8−302916号
In the work to renovate an old slate roof, in the factory, company, parking lot, etc., the site is where dust etc. can enter when removing the existing slate roof, and in the removal work, parts such as removed roofing boards In case of rain or rain, it was necessary to set up temporary houses such as tents, tents, covers, etc. to protect equipment, products, cars, etc. Furthermore, depending on the scale of the construction and the situation of the site, the operation and use of the company, factory, etc. may be temporarily suspended, and the physical and monetary losses and damages that occur during that time are extremely large. For this reason, recently, it has become common to construct a new roof on the existing slate roof while leaving the existing slate roof as much as possible in the formation of the repaired roof.
JP-A-8-302916

ところが、この既設スレート屋根をベースにして、新設屋根板を施工するためには、新設屋根板を既設スレート屋根に取り付けるための金具を既設スレート屋根上に装着しなくてはならない。そのために、既設スレート屋根に金具を装着するためのボルト孔等の加工を施す必要がある。しかし、既設スレート屋根を構成する屋根部材の主原料は、アスベストであり、このアスベストが近年、人体に害を与えることが大きな社会問題となっている。前述したように既設スレート屋根に、金具を装着するための、貫通孔を穿孔する作業では、必ず切粉等による粉塵が発生する。この粉塵は、当然アスベストを含み、周囲に飛散し、又は付近の母屋等の鉄骨に溜まる等して、深刻なる環境汚染を発生する。   However, in order to construct a new roof slab based on this existing slate roof, a metal fitting for attaching the new roof slab to the existing slate roof must be mounted on the existing slate roof. Therefore, it is necessary to process a bolt hole or the like for mounting the metal fitting on the existing slate roof. However, the main raw material of the roof member constituting the existing slate roof is asbestos. In recent years, it has become a big social problem that this asbestos harms the human body. As described above, in the operation of drilling a through hole for mounting a metal fitting on an existing slate roof, dust due to chips or the like is always generated. This dust naturally contains asbestos, and it scatters around or accumulates in a steel frame of a nearby main building or the like, which causes serious environmental pollution.

特に、作業員にとっては、極めて危険な作業環境の中で作業が行わなければならず、その作業着にも密封性のあるものが使用されなければならない。さらに、その既設スレート屋根への加工作業によって生じる粉塵が周囲に飛散しないように、十分なる飛散防御設備を設置しなければならず、大変な時間と手間をかけうることになる。したがって、このような作業は工事費も極めて高いものとなる。さらに、老朽化した既設スレート屋根を改修して新設屋根板を葺成する場合に注意を要する点は他にも沢山ある。たとえば既設スレート屋根は、改修時には、すでに劣化してもろくなって、比較的簡単に割れやすくなっている。このような既設スレート屋根の上に作業員が載って作業を行おうとすると、スレートが簡単に割れ、作業員にとっては極めて危険な作業環境である。また、建築物の内部で作業を行っている作業員も、落下物が当たる危険性がある。   In particular, for workers, the work must be performed in a very dangerous work environment, and the work clothes must also be sealed. Furthermore, it is necessary to install sufficient anti-scattering equipment so that the dust generated by the processing work on the existing slate roof does not scatter around, which can take a lot of time and effort. Therefore, such work is very expensive to construct. In addition, there are many other points that require caution when refurbishing existing slate roofs to create new roofing boards. For example, existing slate roofs are already prone to degradation during refurbishment and are relatively easy to break. When an operator tries to work on such an existing slate roof, the slate breaks easily, which is a very dangerous work environment for the worker. Also, workers who are working inside the building are at risk of falling objects.

したがって、高所での既設スレート屋根の改修工事は、作業員が既設スレート上に載っても落下しないように、十分な安全対策が講じられなければ工事に着手することができない。この為、既設スレート屋根上に工事用足場を作り、或いはネット張りを行い、且つ既設スレート屋根上を歩行するための歩行床(板)が必要である。その歩行床(板)は、図15に示すように、既設スレート屋根の突出したボルト軸を利用して設置し、その設置された歩行床(板)上にネット張りが行われる。   Therefore, the renovation work for the existing slate roof at a high place cannot be started unless sufficient safety measures are taken so that workers do not fall even if they are placed on the existing slate. For this reason, a walking floor (board) is required for making a construction scaffold on the existing slate roof or netting and walking on the existing slate roof. As shown in FIG. 15, the walking floor (plate) is installed using a protruding bolt shaft of an existing slate roof, and netting is performed on the installed walking floor (plate).

また、前述したように、建築物の内部で作業を行っているので、作業員及び設備,製造物等に落下物が当たらないようにするために、なるべく部品点数が少ないものであることが好ましい。さらに、屋根板材や壁板材を支持するための部品である受金具は、特許文献1に記載されたものが、従来より使用されているが、このような受金具は構造材に溶接等にて固着することが多く、そのために工程が多くなりがちであった。   In addition, as described above, since the work is performed inside the building, it is preferable that the number of parts is as small as possible in order to prevent falling objects from hitting workers, equipment, products, and the like. . Furthermore, as for the metal fitting which is a part for supporting a roof board material and a wall board material, what was described in patent document 1 is used conventionally, but such a metal fitting is welded to a structural material etc. In many cases, the process is fixed, and the number of processes tends to increase.

このように、既設スレート屋根を残したままの状態で新設屋根を葺成する場合には既設スレート屋根の母屋,胴縁等の構造材及び既設スレート屋根を固定している既設フックボルトをなるべく利用している。まず、新設屋根の施工にあたり、仮設足場を組む場合の問題点として、改修工事業者とは別に専門業者がその施工に当たるものであった。そのため、仮設足場を施工する間は本来の新設屋根の改修工事は行うことができず、その分長い工期を必要とせざるを得なくなる。   Thus, when forming a new roof with the existing slate roof remaining, use the existing slate roof purlin, structural materials such as the trunk edge, and the existing hook bolts fixing the existing slate roof as much as possible. is doing. First of all, as a problem when constructing a temporary scaffold for the construction of a new roof, a special contractor was involved in the construction separately from the repair contractor. Therefore, while the temporary scaffolding is being constructed, the original new roof cannot be repaired, and a longer construction period is required.

このような仮設足場は極めて専門的な技術が必要で、改修工事業者が行うには余りにも負担がかかるものである。また、作業者は足場から20〜40cm下にある既設スレート屋根に向い作業することになり、その作業性は非常に劣る。仮設足場の施工及び改修工事を行っている間は、既設スレート屋根上に作業員が載ってしまうこともあり、スレートが割れて建築物内に落下する危険性も十分にあるので、このような危険性を防止するためにも室内側にも防護策が必要となる。次に、ネットを張る場合の問題点としては、前述の仮設足場の施工と同様に改修工事業者とは別の専門業者が行うことになり、前述した仮設足場の施工とネット張り作業により、屋根改修工事の工期は、さらに長くなるものであった。   Such temporary scaffolds require very specialized skills and are too burdensome for refurbishment contractors to do. Moreover, an operator will work toward the existing slate roof 20-40 cm below a scaffold, and the workability | operativity is very inferior. While temporary scaffolding construction and renovation work are underway, workers may be placed on the existing slate roof, and there is a risk that the slate will break and fall into the building. Protective measures are also required on the indoor side to prevent danger. Next, as for the problem when installing a net, a specialist other than the refurbishment contractor will perform the same as the construction of the temporary scaffold described above. The construction period of the renovation work was even longer.

改修工事において、作業員は、たとえネットがあるとはいえ、スレート上に載ることは極めて危険であるため、ネット上の流れ方向及びその直角方向に歩行床(板)の設置が必要である。そして、その部分の工事が終了すると、設置していた歩行床(板)を取り外し、また次の工事場所に歩行床を設置する必要がある。また、ネット張り作業中又は改修工事中に、スレートに作業員の足が載り、スレートが割れて落下するのを防止するため、建築物の室内側にも防護策が必要となり、この工事もまた、専門業者を必要とする。   In the renovation work, even if there is a net, it is extremely dangerous for an operator to get on the slate, so it is necessary to install a walking floor (board) in the flow direction on the net and in the direction perpendicular thereto. Then, when the construction of the part is completed, it is necessary to remove the walking floor (board) that has been installed and install the walking floor at the next construction site. Also, in order to prevent workers' feet from being placed on the slate during the net work or renovation work, and to prevent the slate from cracking and falling, a protective measure is also required on the indoor side of the building. Need a professional contractor.

また、改修屋根の施工として、旧スレート屋根(既設スレート屋根)から突き出たフックボルトを利用して新設屋根を葺く為に、図15に示す従来技術のように、予め通し下地材に貫通孔を設け、それにフックボルトを通す工法が存在する。しかし、実際には、既設スレート屋根においてフックボルトが規則正しく配列されていないことが多く、通し下地材に予め穿孔された貫通孔とフックボルトの位置が合わず、事前にフックボルト位置を実測し、手作業中心によって貫通孔を設けるが、更にそれだけでは不十分であることが多く、施工現場では貫通孔を大きくして孔位置を拡げる等の追加作業を行うことが多々あり、施工能率が極めて悪いものである。   In addition, in order to construct a new roof using a hook bolt protruding from an old slate roof (existing slate roof) as a construction of the modified roof, a through-hole is previously formed in the base material as shown in FIG. There is a construction method in which a hook bolt is passed through. However, in practice, the hook bolts are often not regularly arranged on the existing slate roof, and the positions of the through holes and the hook bolts previously drilled in the through base material do not match, and the hook bolt positions are measured in advance, Although a through hole is provided by the center of manual work, it is often insufficient, and there are many additional operations such as enlarging the through hole and expanding the hole position at the construction site, and the construction efficiency is extremely poor. Is.

また、新設屋根は、一般には受金具を通して通し下地材にボルト締めをするものが多いが、この受金具の数は多数であり、現場でこれら受金具をセットするのは大変な時間を要することになる。しかし、この受金具を使用しないと、新設屋根を施工するときのボルト締め時に、新設屋根の山部頂部が僅かに潰れてしまうことがある。また、断面強度を大きくすれば、コストアップになることになる。   In addition, many new roofs are generally bolted to the base material through the brackets, but the number of these brackets is large, and it takes a lot of time to set these brackets on site. become. However, if this bracket is not used, the top of the mountain portion of the new roof may be slightly crushed when bolted when constructing the new roof. Further, increasing the cross-sectional strength increases the cost.

特許文献1には、上記のような欠点が含まれている。すなわち、山部3aの止着具5を利用して吊子体2が形成された帯板6をスレート屋根材上に装着している。このときに、帯板には、前記止着具5のための穴6aが形成されているが、この穴6aのピッチと、前記止着具5の装着ピッチが現場にて一致しないことが多い。しかも、このような止着具5,5,…は、大面積の屋根には多数存在することが多く、ピッチの不一致による穴6aの修正作業は大変な追加工事となり、施工効率が低下するものであった。本発明が解決しようとする課題(技術的課題又は目的)は、屋根改修工事において、既設スレート屋根をそのままにするとともに、前記既設スレート屋根には穿孔又は切断等の加工による切粉の飛散をまったく抑えたり又はその飛散を極めて微々たるものとすることができ、しかも仮設足場,安全ネット張り等の段取施工を最小限として改修屋根の施工を簡易且つ迅速に行うことを実現することである。   Patent Document 1 includes the above-described drawbacks. That is, the band plate 6 on which the hanging body 2 is formed is mounted on the slate roofing material using the fastener 5 of the mountain portion 3a. At this time, a hole 6a for the fastening device 5 is formed in the band plate, but the pitch of the hole 6a and the mounting pitch of the fastening device 5 often do not coincide with each other on site. . Moreover, there are many such fasteners 5, 5,... In a large area roof, and the correction work for the holes 6 a due to the mismatch of the pitch is a great additional work, which reduces the construction efficiency. Met. The problem (technical problem or object) to be solved by the present invention is that the existing slate roof is left as it is in the roof repair work, and the existing slate roof is completely free of chips scattered by processing such as drilling or cutting. It is possible to reduce or prevent the scattering of the roof, and to easily and quickly construct the repaired roof while minimizing setup work such as temporary scaffolding and safety netting.

The locked portion 7 is a portion to which a later-described transfer plate material 10 is connected.

その通し下地材Bは、その長手方向が前記既設スレート屋根Aの各弧状山形部1の長手方向と直交(略直交も含む)するようにして、既設スレート屋根A上に配置される〔図9(A)参照〕。このとき、通し下地材Bの長手方向は、既設スレート屋根Aの複数の弧状山形部1,1,…に亘り載置される。このようにして、複数の通し下地材B,B,…は、前記既設スレート屋根A上に所定間隔をおいて並設されるものである。   The through base material B is arranged on the existing slate roof A so that the longitudinal direction thereof is orthogonal (including substantially orthogonal) to the longitudinal direction of each arcuate mountain-shaped portion 1 of the existing slate roof A [FIG. (See (A)). At this time, the longitudinal direction of the through base material B is placed over the plurality of arcuate mountain-shaped portions 1, 1,... Of the existing slate roof A. In this way, the plurality of through base materials B, B,... Are arranged in parallel on the existing slate roof A with a predetermined interval.

次に、打込みピースCは、図8(A)乃至(D)に示すように、取付基部11の前後方向の前方側に係止溝部12が形成され、その前後方向後方側に立上り支持部13が形成されている。前記取付基部11は、略板状に形成されている。そしてその取付基部11は、平面より見てその幅方向中央箇所で、且つ前後方向に沿って、その長手方向を一致させるようにして長い溝形状の係止溝部12が形成されている〔図8(D)参照〕。該係止溝部12は、その長手方向の一端が開口しており、挿入開口12aと称する。該挿入開口12aは、前記取付基部11の前後方向における前方端縁に位置している。前記取付基部11の幅方向両側端辺は、前記挿入開口12aの位置に向って幅方向両側前方がしだいに狭くなる傾斜辺としている。   Next, as shown in FIGS. 8A to 8D, the driving piece C has a locking groove portion 12 formed on the front side in the front-rear direction of the mounting base 11, and a rising support portion 13 on the rear side in the front-rear direction. Is formed. The mounting base 11 is formed in a substantially plate shape. The attachment base portion 11 is formed with a long groove-shaped locking groove portion 12 at the center in the width direction when viewed from the plane and along the front-rear direction so as to coincide with the longitudinal direction [FIG. (See (D)). The locking groove 12 is open at one end in the longitudinal direction and is referred to as an insertion opening 12a. The insertion opening 12a is located at the front edge of the mounting base 11 in the front-rear direction. Both side edges in the width direction of the mounting base 11 are inclined sides that gradually narrow toward the position of the insertion opening 12a.

また、取付基部11の幅方向両側箇所には、補強用リブ11aが形成されている。前記補強用リブ11aは、断面略半円状に形成されたものであり取付基部11の幅方向両側で且つ裏面側に膨出するようにして2本形成されている。さらに、前記係止溝部12は、係止溝部の形成箇所における取付基部11の下面側(裏面側)箇所には幅方向に沿ってその断面に略円弧状とした凹み面部11bが形成されている。該凹み面部11bは、その取付基部11の前後方向に沿って、凹み溝条となるようにして形成されている。そして、その凹み面部11bの断面円弧形状は、前記既設スレート屋根Aの弧状山形部1の頂部の円弧形状に略等しくなるように形成されることが好ましい〔図8(E),(F)参照〕。このように取付基部11に凹み面部11bが形成されることにより、その打込みピースCは、前記既設フックボルト5を利用して、その装着状態を安定させることができる。   Reinforcing ribs 11 a are formed at both sides in the width direction of the mounting base 11. The reinforcing ribs 11a are formed to have a substantially semicircular cross section, and two reinforcing ribs 11a are formed so as to bulge on both sides in the width direction of the mounting base 11 and on the back side. Further, the locking groove portion 12 is formed with a concave surface portion 11b having a substantially arc shape in its cross section along the width direction at the lower surface side (back surface side) portion of the mounting base portion 11 at the position where the locking groove portion is formed. . The concave surface portion 11b is formed so as to form a concave groove along the front-rear direction of the mounting base portion 11. And it is preferable to form the cross-sectional arc shape of the recessed surface part 11b so that it may become substantially equal to the arc shape of the top part of the arcuate mountain-shaped part 1 of the said existing slate roof A [refer FIG.8 (E), (F). ]. By forming the recessed surface portion 11b in the mounting base portion 11 in this way, the driving piece C can stabilize the mounting state using the existing hook bolt 5.

また、前記係止溝部12の挿入開口12a付近における内側縁は、その係止溝部12の奥側に向うにしたがい、しだいに幅が狭くなるように形成されている。この部分で最も幅の狭い箇所は、前記既設フックボルト5のボルト軸部5aの直径よりも狭くなるようになっている。この次第に狭くなる部位を係止溝部12の案内領域12bと称する。そして、前記係止溝部12の形成箇所における取付基部11の両側部分は弾性的に拡開可能としている。すなわち、係止溝部12の幅方向両側を広げることができると共に、一旦、拡げられた状態から、元の形状に戻ろうとする弾性力を備えたものである〔図14(A)乃至(C)参照〕。その案内領域12bでは、前記係止溝部12の幅方向両側の内側縁が傾斜辺12bとして、形成されているが、さらにその傾斜辺12bが複数形成されて略鋸歯形状となっているものが存在する。この案内領域12bが前記係止溝部12に形成されることにより、前記既設フックボルト5のボルト軸部5aに挿入したときに、一旦、係止溝部12内に入り込んだボルト軸部5aは、抜け出すことができないようにすることができるものである。 Further, the inner edge of the locking groove portion 12 in the vicinity of the insertion opening 12a is formed so that the width gradually becomes narrower toward the back side of the locking groove portion 12. The narrowest portion in this portion is narrower than the diameter of the bolt shaft portion 5 a of the existing hook bolt 5. The gradually narrowing portion is referred to as a guide region 12b of the locking groove portion 12. And both the side parts of the attachment base 11 in the formation location of the said locking groove part 12 can be expanded elastically. That is, both sides in the width direction of the locking groove 12 can be widened, and the elastic groove is provided with an elastic force to return to the original shape from the expanded state [FIGS. 14 (A) to (C). reference〕. In the guide region 12b, as the engaging groove 12 both sides in the width direction of the inner edge is inclined side 12b 1 of have been formed, which is further the inclined sides 12b 1 is formed with a plurality a substantially sawtooth shape Exists. By forming the guide region 12b in the locking groove portion 12, the bolt shaft portion 5a once entering the locking groove portion 12 is pulled out when inserted into the bolt shaft portion 5a of the existing hook bolt 5. It is something that can be prevented.

その取付基部11の前後方向後方側に形成される立上り支持部13は、図8(A)乃至(C)に示すように、立上り板片13aと頂部片13bとから構成されている。該立上り板片13aは前記取付基部11に対して略直角状に屈曲形成され、また前記頂部片13bは、前記立上り板片13aに対して略直角で且つ水平状となるように形成されている。前記取付基部11と立上り板片13aとの間には、補強用の立上りリブ13cが形成されている。その立上り支持部13は前記通し下地材Bの屋根板受部8を裏面側から支持固定する役目をなすものである。   As shown in FIGS. 8A to 8C, the rising support portion 13 formed on the rear side in the front-rear direction of the mounting base portion 11 is composed of a rising plate piece 13a and a top piece 13b. The rising plate piece 13a is bent at a substantially right angle with respect to the mounting base portion 11, and the top piece 13b is formed at a substantially right angle with respect to the rising plate piece 13a and in a horizontal shape. . A reinforcing rising rib 13c is formed between the mounting base 11 and the rising plate piece 13a. The rising support portion 13 serves to support and fix the roof plate receiving portion 8 of the through base material B from the back surface side.

次に、渡し板材10は、前記既設スレート屋根A上に並設された通し下地材Bに隣接して配置されるものである。その渡し板材10は、図7(B)に示すように、渡し主板10aの幅方向両側に前記通し下地材Bの載置部6の先端に形成された係合部に係合することができる被係合部10b,10bが形成されている。また、前記渡し主板10aには、長手方向に沿って複数の補強部10c,10c,…が形成されて補強され、渡し板材10の力学的強度を向上させるものである。その補強部10cは、断面略逆門形状に形成され、渡し板材10の幅方向寸法に応じて適正な数だけ形成される。   Next, the delivery board | plate material 10 is arrange | positioned adjacent to the through base material B arranged in parallel on the said existing slate roof A. As shown in FIG. As shown in FIG. 7 (B), the transfer plate member 10 can be engaged with engagement portions formed at the front end of the placement portion 6 of the through base material B on both sides in the width direction of the transfer main plate 10a. Engaged portions 10b and 10b are formed. In addition, a plurality of reinforcing portions 10c, 10c,... Are formed along the longitudinal direction on the transfer main plate 10a to be reinforced, thereby improving the mechanical strength of the transfer plate material 10. The reinforcing portions 10c are formed in a substantially inverted gate shape in cross section, and are formed in an appropriate number according to the width direction dimension of the transfer plate material 10.

前記両被係合部10bは、その一方側が断面略コ字形状に形成され、他方側が断面略門形状等に折曲形成されている。そして、水上、水下方向に沿って隣接する前記通し下地材B,B間の被係止部7と、前記載置部6の先端に形成された係合部9に、それぞれ重合又は係止により連結される〔図3(A)乃至(C)参照〕。また、通し下地材Bと渡し板材10とのその他の係合構造としては、上記タイプに限定されるものではなく、馳折り係合タイプ,嵌合タイプ,差込み係合タイプ等の種々の形状が存在する。   The engaged portions 10b are formed such that one side thereof has a substantially U-shaped cross section and the other side is bent into a substantially gate-shaped cross section. And it superposes or locks onto the locked portion 7 between the through base materials B adjacent to each other along the water and underwater directions, and the engaging portion 9 formed at the tip of the placing portion 6. [See FIGS. 3A to 3C]. Further, the other engagement structure between the through base material B and the transfer plate member 10 is not limited to the above-mentioned type, and various shapes such as a folding engagement type, a fitting type, and a plugging engagement type are available. Exists.

また、その渡し板材10は、前記通し下地材Bに対して長手方向に沿って移動自在となっており、且つ新設屋根Dの葺成が完了するとともに既設スレート屋根A及び新設屋根Dの施工完了箇所から随時,隣の新たな新設屋根施工部位へ移動させるものである〔図12(A),(B)参照〕。この移動自在となる構造では、前記渡し板材10が隣接する前記通し下地材B,B間で相互に摺動することができるように接触している(図5参照)。そして、前記通し下地材B上に施工される新設屋根Dの葺成方向とともに渡し板材10が移動することができるようにしたものである。このような構造としているので、新設屋根Dの葺成作業の最終位置で、その渡し板材10が隣接する通し下地材B,B間から取り外される。すなわち、新設屋根Dの葺成完了時には、渡し板材10は、改修屋根に存在しない。しかし、この渡し板材10が新設屋根Dの葺成完了とともに取り外されず、そのまま新設屋根Dとともに残しておいてもかまわない。   Further, the transfer plate 10 is movable along the longitudinal direction with respect to the through base material B, and the formation of the new roof D is completed and the construction of the existing slate roof A and the new roof D is completed. From time to time, it is moved from time to time to the next new roof construction site (see FIGS. 12A and 12B). In this movable structure, the transfer plate member 10 is in contact with each other so as to be able to slide between the adjacent base materials B and B (see FIG. 5). And the transfer board | plate material 10 can be moved now with the formation direction of the new roof D constructed | assembled on the said through base material B. As shown in FIG. Since it is set as such a structure, the transfer board | plate material 10 is removed from between the adjacent through base materials B and B in the final position of the laying work of the new roof D. FIG. That is, at the completion of the formation of the new roof D, the transfer plate member 10 does not exist on the modified roof. However, the transfer plate 10 may be left together with the new roof D without being removed when the new roof D is completely formed.

次に、新設屋根Dは、複数の新設屋根板D1 ,D1 ,…から構成されている。ここで、新設屋根とは、改修屋根において既設スレート屋根Aに対して新たに施工される屋根のことをいう。その新設屋根板D1 は、図6(A)乃至(C)に示すように、薄板金属材から形成されたものであり、山形部16と底部17とからなり、この山形部16と底部17とが交互に連続している。そして、隣接する新設屋根板D1 ,D1 の山形部16同士を重合して連結する重合タイプとしたものである〔図6(D)参照〕。その山形部16の断面形状は、略台形状に形成されたものであり、頂片16aの幅方向両側より傾斜片16b,16bが形成されている。具体的には、一つの新設屋根板D1 には、4個の山形部16,16,…が形成され、一つの山形部16の底部17からの高さは、約20mm乃至30mm程度であり、好ましくは25mmである。 Next, the new roof D is composed of a plurality of new roof plates D 1 , D 1 ,. Here, the new roof refers to a roof newly constructed with respect to the existing slate roof A in the modified roof. As shown in FIGS. 6A to 6C, the new roof plate D 1 is formed from a thin metal plate material, and includes a mountain-shaped portion 16 and a bottom portion 17, and the mountain-shaped portion 16 and the bottom portion 17. And are continuous alternately. Then, is obtained by a polymerization type connecting by polymerizing a chevron portion 16 with each other in new shingle D 1, D 1 adjacent [see FIG. 6 (D)]. The cross-sectional shape of the mountain-shaped portion 16 is substantially trapezoidal, and inclined pieces 16b and 16b are formed from both sides in the width direction of the top piece 16a. Specifically, one new shingle D 1, 4 pieces of mountain-shaped portions 16, 16, ... are formed, the height from the bottom 17 of one chevron portion 16 is located about 20mm to 30mm approximately , Preferably 25 mm.

また、頂片16aの幅方向寸法は、25mm乃至30mm程度であり、好ましくは28mmである。さらに、傾斜片16b,16bの立上り角度θ(すなわち、台形状とした山形部16の両傾斜片16b,16bの下端箇所における両内角)は、55度乃至60度程度である。このように新設屋根板D1 は、山形部16が従来のこの種の折板屋根板の山形部に比較して前記両傾斜片16b,16bの立上り角度θが大きく形成され、且つ前記頂片16aの幅方向寸法が山形部16の高さ寸法よりも大きく形成されたものである。すなわち、山形部16において、傾斜片16bの立上り角度θを約50度以上として十分に確保するとともに、(頂片16aの幅方向寸法)>(山形部16の高さ寸法)なる関係とする。この条件に応じた新設屋根板D1 を使用されることが好ましい。 Moreover, the width direction dimension of the top piece 16a is about 25 mm thru | or 30 mm, Preferably it is 28 mm. Further, the rising angle θ of the inclined pieces 16b, 16b (that is, both inner angles at the lower end portions of the inclined pieces 16b, 16b of the trapezoidal portion 16) is about 55 to 60 degrees. Thus, the new roof plate D 1 is formed such that the angled portion 16 has a larger rising angle θ of the inclined pieces 16b, 16b than the angled portion of this type of folded plate roof plate, and the top piece. The width direction dimension of 16a is formed larger than the height dimension of the angle portion 16. That is, in the angle portion 16, the rising angle θ of the inclined piece 16 b is sufficiently secured to be about 50 degrees or more, and the relation of (width direction dimension of the top piece 16 a)> (height dimension of the angle portion 16) is established. It is preferable to use a new roof plate D 1 according to this condition.

これに対して、従来タイプの屋根板材は、(山高寸法38mm),(山幅寸法35mm),(山形部の両辺立上り角度45度)である。このような従来タイプの屋根板材に対して本発明における新設屋根板D1 の山形部16は、座屈荷重が15%向上している。これによって本発明における新設屋根板D1 は、金属板の肉厚を薄くすることが可能となり、その板厚は0.5mm,0.6mm程度にすることができるものである。また、その新設屋根板D1 は、必ずしも上記条件を満たさなければならないものではなく、多少の条件が満たされていなくても構わない。これによって、山形部16は、前記通し下地材Bの屋根板受部8に受金具等の支持部材を一切,使用することなく、直接,ドリルビス等の固着具18を介して固定することができる。そして、その重合された山形部16,16同士の連結箇所及び単独の山形部16箇所と前記通し下地材Bとの固着具18による固定箇所では、座屈荷重等の種々の荷重に十分に対応することができる極めて強固な構造とし、且つ十分な耐久強度を得ることができるものである。 On the other hand, the conventional roofing board materials are (mountain height 38 mm), (mountain width 35 mm), (both sides rising angle 45 degrees). Compared to such a conventional roof plate material, the buckle load of the mountain-shaped portion 16 of the new roof plate D 1 in the present invention is improved by 15%. As a result, the new roof plate D 1 according to the present invention can reduce the thickness of the metal plate, and the thickness can be reduced to about 0.5 mm and 0.6 mm. In addition, the newly installed roof board D 1 does not necessarily have to satisfy the above conditions, and some conditions may not be satisfied. As a result, the mountain-shaped portion 16 can be directly fixed to the roof plate receiving portion 8 of the through base material B through a fixing tool 18 such as a drill screw without using any support member such as a metal fitting. . The superposed chevron portions 16, 16 are connected to each other, and the single chevron portion 16 places and the fixing portion 18 with the through base material B are fixed to various loads such as buckling loads. It is possible to obtain a very strong structure that can be obtained and to obtain sufficient durability.

そして、隣接する新設屋根板D1 ,D1 の最も外側に位置する山形部16,16同士が重合されて、隣接する新設屋根板D1 ,D1 同士が幅方向に連結される。その重合連結された山形部16,16及びその他の山形部16,16,…がドリルビス等の固着具18にて前記頂片16aを貫通して前記通し下地材Bの屋根板受部8にねじ込まれ、山形部16,16,…が屋根板受部8に固定されることにより新設屋根板D1 が屋根板受部8上に施工されてゆく。前記固着具18は、前述したようにドリルビスとしたものであるが、その他に鉄板ビス,タッピングビス等のように相手側に内螺子を形成しつつ螺子止めできるタイプのものや、ボルト等が固着具18として使用されるものである。 The chevron portions 16, 16 between which most located outside the new shingle D 1, D 1 adjacent is polymerized, the adjacent newly shingle D 1, D 1 with each other is connected in the width direction. .. And the other chevron portions 16, 16,... Penetrate through the top piece 16 a with a fixing tool 18 such as a drill screw and are screwed into the roof plate receiving portion 8 of the through base material B. Are fixed to the roof plate receiving portion 8, the newly installed roof plate D 1 is constructed on the roof plate receiving portion 8. The fixing tool 18 is a drill screw as described above, but other types such as an iron plate screw, a tapping screw, etc. that can be screwed while forming an internal screw on the other side, or a bolt is fixed. Used as a tool 18.

また、重合する山形部16,16同士の上側に位置する山形部16の外側傾斜片には外方に断面略円弧状に膨出する膨出条16cが形成されている。該膨出条16cは、重合する山形部16,16同士の下側に位置する山形部16の傾斜片16bとの間に空隙部Sを構成するように構成され、毛管現象による雨水を遮断し、雨水の浸入を防止することができる。また、新設屋根板D1 の他のタイプとしては、馳締タイプ,山形部16,16同士の連結に嵌合キャップ材が使用されるものである。 In addition, a bulging strip 16c that bulges outward in a substantially circular arc shape is formed on the outer inclined piece of the chevron 16 located above the chevron chevron 16 and 16 to be overlapped. The ridge 16c is configured so as to form a gap S between the angled portion 16b of the mountain-shaped portion 16 positioned below the overlapping mountain-shaped portions 16, 16, and blocks rainwater due to capillary action. Can prevent the intrusion of rainwater. Further, other types of new shingle D 1, in which馳締type, the connection between the mountain-shaped portions 16, 16 fitted cap material are used.

次に、改修屋根の施工について、図4及び図9乃至図12に基づいて説明する。まず図4(A),図9(A)に示すように、断面波形状の既設スレート屋根Aの弧状山形部1の頂部表面と、該頂部上から突出した既設フックボルト5のボルト軸部5aに螺合された既設ナット5cとの間に、打込みピースCをその係止溝部12の挿入開口12a側から挿入し、ハンマー等の工具にて打ち込み係止固定する〔図4(A)及び図14(B),(E)参照〕。その打込みピースCの立上り支持部13上に前記通し下地材Bの屋根板受部8を配置して、前記立上り板片13aの頂部片13bにドリルビス等の固着具にて固着する。また、前記既設フックボルト5が腐食していたり、又は脱落しているために、既設フックボルト5を利用して打込みピースCを既設スレート屋根A上に装着することができないような、既設フックボルト5の使用不能箇所では、別部材のビス19によって通し下地材Bが既設スレート屋根A上に装着される。具体的には、前記既設構造材4が存在する位置に合わせて前記既設スレート屋根Aに小孔を穿孔する。そして、前記通し下地材Bの被係止部7の下部面7aを前記小孔箇所に載置し、その小孔に前記ビス19の螺子軸部を挿通させ、前記既設構造材4に直接、ねじ込み締め付けてゆく。このようにして、通し下地材Bをビス19によって直接既設スレート屋根A上へ装着を行うものである〔図1,図2,図3(C)等参照〕。その別部材としたビス19は、ドリルビス等が使用され、このドリルビスによって、既設スレート屋根A及び既設構造材4を直接穿孔且つ螺子込みができるものである。   Next, the construction of the repaired roof will be described with reference to FIGS. 4 and 9 to 12. First, as shown in FIGS. 4 (A) and 9 (A), the top surface of the arc-shaped chevron 1 of the existing slate roof A having a cross-sectional wave shape, and the bolt shaft portion 5a of the existing hook bolt 5 protruding from the top. The driving piece C is inserted from the side of the insertion opening 12a of the locking groove 12 between the existing nut 5c screwed into the locking nut 12 and driven and locked with a tool such as a hammer [FIG. 4 (A) and FIG. 14 (B), (E)]. The roof plate receiving portion 8 of the through base material B is disposed on the rising support portion 13 of the driving piece C, and is fixed to the top piece 13b of the rising plate piece 13a with a fixing tool such as a drill screw. Further, since the existing hook bolt 5 is corroded or dropped out, the existing hook bolt 5 cannot be mounted on the existing slate roof A by using the existing hook bolt 5. In the unusable part 5, the through base material B is mounted on the existing slate roof A by a screw 19 as another member. Specifically, a small hole is drilled in the existing slate roof A in accordance with the position where the existing structural material 4 exists. Then, the lower surface 7a of the locked portion 7 of the through base material B is placed in the small hole portion, the screw shaft portion of the screw 19 is inserted into the small hole, and directly into the existing structural member 4 Tighten with screws. In this way, the through base material B is directly mounted on the existing slate roof A with the screw 19 (see FIGS. 1, 2, 3C, etc.). As the separate member 19, a drill screw or the like is used, and the existing slate roof A and the existing structural member 4 can be directly drilled and screwed by this drill screw.

このようにして、前記通し下地材Bの長手方向を既設スレート屋根Aの弧状山形部1に直交させて、その載置部6が弧状山形部1の頂部に当接するようにして載置する〔図4(B),図9(A)参照〕。次に、前記既設スレート屋根A上に固定された通し下地材Bの載置部6の先端に形成された係合部9に渡し板材10の一方側の被係合部10bが係合されつつ、渡し板材10が既設スレート屋根A上に配置される〔図5,図9(B)参照〕。このとき、被係合部10bは載置部6のいずれの位置に配置しておいてもかまわないが、被係合部10bが屋根板受部8に近接又は当接する状態に配置しておくことが好ましい。そして、図5に示すように、次位の既設フックボルト5箇所に、新たな打込みピースCにて固定して通し下地材Bを装着してゆく。   In this way, the through base material B is placed so that the longitudinal direction of the through base material B is perpendicular to the arcuate mountain-shaped portion 1 of the existing slate roof A so that the placing portion 6 is in contact with the top of the arc-shaped mountain-shaped portion 1 [ FIG. 4 (B) and FIG. 9 (A)]. Next, the engaged portion 10b on one side of the transfer plate member 10 is engaged with the engaging portion 9 formed at the tip of the placement portion 6 of the through base material B fixed on the existing slate roof A. Then, the transfer plate member 10 is disposed on the existing slate roof A [see FIGS. 5 and 9B]. At this time, the engaged portion 10b may be disposed at any position of the placement portion 6, but is disposed in a state in which the engaged portion 10b is in proximity to or in contact with the roof plate receiving portion 8. It is preferable. Then, as shown in FIG. 5, the base material B is attached to the next five existing hook bolts by fixing with new driving pieces C.

次いで、前記渡し板材10を既設スレート屋根Aの弧状山形部1の長手方向(通し下地材Bの長手方向に直交する方向でもある)に沿って少しずらすように移動させ、前記渡し板材10の他方側の被係合部10b箇所を上方に少し持ち上げながら、前記通し下地材Bの被係止部7に係合させる(図10参照)。このようにして、前記渡し板材10は、図5に示すように、長手方向(前記既設スレート屋根Aの弧状山形部1に直交する方向)に沿って摺動状態で移動自在となっている。これを図10,図11(A)に示すように、順次、繰り返して既設スレート屋根A上に通し下地材B及び渡し板材10を交互に複数並設する。前記通し下地材B及び渡し板材10は、既設スレート屋根Aの弧状山形部1の長手方向に沿って所定間隔又は等間隔に配置されることになる。   Next, the transfer plate member 10 is moved so as to be slightly shifted along the longitudinal direction of the arcuate chevron 1 of the existing slate roof A (which is also a direction orthogonal to the longitudinal direction of the through base material B), and the other of the transfer plate members 10 is moved. While the portion to be engaged 10b on the side is slightly lifted upward, it is engaged with the engaged portion 7 of the through base material B (see FIG. 10). In this way, as shown in FIG. 5, the transfer plate member 10 is movable in a sliding state along the longitudinal direction (direction perpendicular to the arcuate mountain-shaped portion 1 of the existing slate roof A). As shown in FIG. 10 and FIG. 11 (A), a plurality of base materials B and transfer plate materials 10 are alternately arranged side by side sequentially on the existing slate roof A. The through base material B and the transfer plate material 10 are arranged at predetermined intervals or at equal intervals along the longitudinal direction of the arcuate mountain-shaped portion 1 of the existing slate roof A.

次に、図5,図11(B)に示すように、並設した通し下地材B,B,…上に新設屋根板D1 を葺成する。新設屋根板D1 は、その長手方向が前記通し下地材Bの屋根板受部8の長手方向に対して直交するように配置されるものであって、その新設屋根板D1 の葺成方向は、屋根板受部8の長手方向に沿って行われるものである。前記渡し板材10は、図12(B)に示すように、前記通し下地材Bの長手方向に沿って移動自在とし、新設屋根Dの葺成方向にしたがって、前記渡し板材10を移動させることができる。すなわち、新設屋根Dの所定の施工が完了した領域から、図12(B)に示す矢印方向に前記渡し板材10を引き出すようにして、該渡し板材10を新たな未施工領域に配置させるものである。このとき、既設スレート屋根A上に予め通し下地材Bを渡し板材10の移動方向に設置しておく。このようにして、各渡し板材10,10,…を次の新設屋根Dの施工領域に移動させてゆくものであり、所定の範囲に新設屋根板D1 が配置されてゆくとともに、渡し板材10も移動してゆくことになる。 Next, as shown in FIGS. 5 and 11B, a new roof plate D 1 is formed on the through base materials B, B,. The new roof plate D 1 is arranged so that the longitudinal direction thereof is orthogonal to the longitudinal direction of the roof plate receiving portion 8 of the through base material B, and the direction in which the new roof plate D 1 is formed. Is performed along the longitudinal direction of the roof plate receiving portion 8. As shown in FIG. 12 (B), the transfer plate material 10 is movable along the longitudinal direction of the through base material B, and the transfer plate material 10 is moved in accordance with the direction in which the new roof D is formed. it can. That is, from the area where the predetermined construction of the new roof D is completed, the delivery board material 10 is drawn out in the direction of the arrow shown in FIG. is there. At this time, the base material B is previously installed on the existing slate roof A in the moving direction of the transfer plate material 10. In this way, each of the passing plate members 10, 10,... Is moved to the construction area of the next new roof D, and the new roof plate D 1 is arranged in a predetermined range. Will also move.

この渡し板材10と前記通し下地材Bの載置部6は、作業員の歩行用通路として利用する等、種々の作業ができる。また前記渡し板材10は、道具のストックヤード(置き場)として利用できる。これらにより、作業効率を向上させることができる。また、新設屋根Dの葺成完了にともない、渡し板材10は撤去され、他の改修屋根工事で繰り返し利用することができる。   The delivery plate material 10 and the placement portion 6 for the through base material B can be used for various operations such as use as a walking path for workers. The transfer board 10 can be used as a tool stock yard. As a result, work efficiency can be improved. Moreover, with the completion of the formation of the new roof D, the transfer board 10 is removed and can be repeatedly used in other repaired roof constructions.

図13は、改修屋根の施工において新設屋根Dの施工完了箇所から前記渡し板材10が移動することにより撤去された状態を示すものである。該渡し板材10は、前述したように通し下地材Bに対して摺動させ、新設屋根Dの完了した箇所から随時移動されてゆくものであり、改修屋根の全体の施工が完了することによって撤去されてゆくものである。本発明においては、足場、ネット等を必要とせずに、既設スレート屋根Aに新設屋根Dを葺成することができ、既設スレート屋根Aの既設フックボルト5の配列ピッチ寸法がたとえ不揃いであっても、現場にて十分に対応することができ、引いては特別な熟練を要することがない等の効果を有する。   FIG. 13 shows a state where the transfer plate material 10 has been removed by moving from the construction completion location of the new roof D in the construction of the repaired roof. The transfer plate 10 is slid with respect to the through base material B as described above, and is moved from time to time from the completed position of the new roof D, and is removed when the entire construction of the repaired roof is completed. It will be done. In the present invention, the new roof D can be formed on the existing slate roof A without requiring a scaffold, a net, etc., and the arrangement pitch dimensions of the existing hook bolts 5 of the existing slate roof A are uneven. However, it can be adequately handled in the field, and has the effect that it does not require special skill.

すなわち、通し下地材Bを既設スレート屋根A上に打込みピースCを介して固定するものであり、既設スレート屋根Aのスレート屋根材A1 を既設構造材4に固定するための既設フックボルト5のピッチ寸法が不揃いであったとしても、このようなことに係わりなく、打込みピースCのみを既設スレート屋根Aの既設フックボルト5を介して固定し、打込みピースCの係止部12と、通し下地材Bの被係止部7との係止によってのみ、前記通し下地材Bが既設スレート屋根A上に固定される構造としたものである。したがって、たとえ前記既設フックボルト5がどのようなピッチ寸法であろうとも、また不揃いであったとしても、通し下地材Bを既設スレート屋根Aに簡易且つ迅速に固定することができる。 That is, the through base material B is fixed on the existing slate roof A via the driving piece C, and the existing hook bolt 5 for fixing the slate roof material A 1 of the existing slate roof A to the existing structural material 4 is provided. Regardless of this, even if the pitch dimensions are not uniform, only the driving piece C is fixed through the existing hook bolt 5 of the existing slate roof A, and the locking portion 12 of the driving piece C is passed through. The through base material B is fixed onto the existing slate roof A only by locking the material B with the locked portion 7. Therefore, even if the existing hook bolts 5 have any pitch size or are not uniform, the through base material B can be simply and quickly fixed to the existing slate roof A.

このように、打込みピースCが構成部材として付加されていることにより、前記通し下地材B側には、現場の既設フックボルト5のピッチ寸法に対応した貫通孔を穿孔することなく、該既設フックボルト5を利用し、打込みピースCを介して前記通し下地材Bを固定することができるものであり、この改修屋根の施工に熟練した技術や、熟練した作業員を必要としないものであり、ひいては低価格にて施工することができる。   In this way, the driving piece C is added as a constituent member, so that the existing hook can be formed on the through base material B side without drilling a through hole corresponding to the pitch dimension of the existing hook bolt 5 at the site. The bolt 5 can be used to fix the through base material B through the driving piece C, which does not require skill and skilled workers in the construction of the modified roof, As a result, it can be constructed at a low price.

また、新設屋根Dの施工時においては、前記渡し板材10を作業員のための作業用通路としたり、或いは道具のストックヤード(置き場所)にすることができる。すなわち、渡し板材10を両通し下地材B,Bに長手方向に移動自在に載置することで、両通し下地材B,B間を往来する場合に作業員の安全を確保したり、或いは道具類の落下をその渡し板材10にて受け止め、既設スレート屋根Aを損傷することを防止できる。   Further, when the new roof D is constructed, the transfer plate material 10 can be used as a work passage for workers, or can be used as a tool stock yard (place). That is, by placing the transfer plate material 10 on the both through base materials B and B so as to be movable in the longitudinal direction, it is possible to ensure the safety of the worker when traveling between the two through base materials B and B, or the tools. It is possible to prevent the existing slate roof A from being damaged by receiving the falling of the kind with the transfer plate material 10.

さらに、その渡し板材10を両通し下地材B,Bの長手方向に沿って移動自在であるため、新設屋根板D1 ,D1 を葺成作業にともなって移動させることで、作業の安全を図り、且つ作業効率を向上させることができる。また、渡し板材10を設けることにより、既設スレート屋根A上の不安定な空きスペースも少なくすることができる。さらに新設屋根Dが葺成されて改修屋根の施工が完了した後には、前記渡し板材10は、撤去するものであり、渡し板材10を別の改修屋根工事にて何度でも繰り返し使用することができるものである。 Furthermore, since the transfer plate 10 can be moved along the longitudinal direction of the base materials B and B, the new roof plates D 1 and D 1 can be moved along with the generation work, so that the work safety can be improved. In addition, the working efficiency can be improved. In addition, by providing the transfer plate member 10, an unstable empty space on the existing slate roof A can be reduced. Furthermore, after the new roof D is formed and the construction of the repaired roof is completed, the transfer board material 10 is removed, and the transfer board material 10 can be used repeatedly in another repair roof work. It can be done.

また、前記渡し板材10には長手方向に沿って略溝状の補強部10c,10c,…が形成されることによって、渡し板材10の断面係数を大きくし、力学的強度を向上させることができる。また、補強部10c,10c,…が形成されることにより、渡し板材10の板厚を薄くし、軽量化を実現することができる。具体的には、渡し板材10の板厚は、0.5mmとすることができ、軽量化を実現でき、作業員の負担を減少させることができる。   Further, by forming substantially groove-shaped reinforcing portions 10c, 10c,... Along the longitudinal direction on the transfer plate member 10, the cross section coefficient of the transfer plate member 10 can be increased and the mechanical strength can be improved. . Further, by forming the reinforcing portions 10c, 10c,..., It is possible to reduce the plate thickness of the transfer plate material 10 and realize weight reduction. Specifically, the thickness of the transfer plate member 10 can be set to 0.5 mm, the weight can be reduced, and the burden on the worker can be reduced.

また、前記新設屋根板D1 において、その山形部16の両傾斜片16b,16bの立上り角度θが大きく形成され、且つ前記頂片16aの幅方向寸法が山形部16の高さ寸法よりも大きく形成されたものとする。すなわち、山形部16において、傾斜片16bの立上り角度θを約50度以上とし、且つ(頂片16aの幅方向寸法)>(山形部16の高さ寸法)なる関係とする。これによって、新設屋根板D1 は、力学的強度が大きくなり、前記通し下地材Bの屋根板受部8上に施工するときに、山形部16の頂片16a箇所と通し下地材Bとをドリルビス等の固着具18を介して固定することで、受金具等の支持具を設けなくとも十分に耐久性のあるものにできる。 Further, in the new roof plate D 1 , the rising angle θ of both inclined pieces 16 b, 16 b of the mountain portion 16 is formed large, and the width direction dimension of the top piece 16 a is larger than the height dimension of the mountain portion 16. It shall be formed. That is, in the angle portion 16, the rising angle θ of the inclined piece 16 b is set to about 50 degrees or more, and (the width dimension of the top piece 16 a)> (height dimension of the angle portion 16). As a result, the new roof plate D 1 has increased mechanical strength, and when it is constructed on the roof plate receiving portion 8 of the through base material B, the top piece 16a of the mountain-shaped portion 16 and the through base material B are connected. By fixing via a fixing tool 18 such as a drill screw, it can be made sufficiently durable without providing a support such as a metal fitting.

本発明における工法において、前記渡し板材10を新設屋根Dの葺成方向とともに、移動させることで、葺成作業をより一層効率的にできる。すなわち、新設屋根Dの葺成方向に伴って、渡し板材10が移動できるので、その渡し板材10を介して隣接する通し下地材B,B間を往来でき、またその渡し板材10上に道具等を置いておくことができるので、葺成作業を効率的にすることができるとともに、作業員の安全性の確保、及び道具類等の落下防止ができるものであり、新設屋根Dを折板屋根とした場合に好適であり、折板屋根の葺成を極めて効率的に行うことができる。また、通し下地材Bは、弧状山形部1箇所から突出する既設フックボルト5によって、既設スレート屋根A上に極めて強固に固定することができ、ひいては新設屋根板D1 を強固に支持することができるものである。 In the construction method according to the present invention, by moving the transfer plate member 10 together with the direction of formation of the new roof D, the formation work can be made more efficient. That is, since the transfer plate material 10 can be moved along with the direction in which the new roof D is formed, it is possible to travel between adjacent base materials B and B via the transfer plate material 10, and tools etc. on the transfer plate material 10. It is possible to keep the construction work efficient, to ensure the safety of workers and to prevent the fall of tools, etc. In this case, the folded roof can be formed very efficiently. Further, the through base material B can be fixed extremely firmly on the existing slate roof A by the existing hook bolt 5 protruding from one arcuate chevron, and as a result, the new roof plate D 1 can be firmly supported. It can be done.
