Description
本発明は、鉄筋コンクリート造によるドーム状の構築物の建築方法に関する。 The present invention relates to a method for constructing a dome-shaped structure using reinforced concrete.
鉄筋コンクリート造の屋根がドーム状の建築物は、従来の陸屋根スラブのような水平な屋根の建築物のように簡単に施工することができない。
例えば、特許文献１及び２にドーム状の建築物が開示されているが、屋根がドーム状の建築物は、屋根全体がドーム状の半球形をしていることから、最初にドーム屋根の下端に木製合板かFRPで成形した型枠でドーム状に組み立ててから、その上に鉄筋を配筋してコンクリートを流し込んで打設し、鉄筋コンクリート造のドーム屋根を建築する必要がある。
Buildings with dome-shaped roofs made of reinforced concrete cannot be constructed as easily as buildings with horizontal roofs such as traditional flat slab roofs.
For example, Patent Documents 1 and 2 disclose dome-shaped buildings, but in the case of a building with a dome-shaped roof, because the entire roof is dome-shaped and hemispherical, it is necessary to first assemble a formwork made of wooden plywood or FRP at the bottom edge of the dome roof into a dome shape, and then arrange reinforcing bars on top and pour and cast concrete to construct a reinforced concrete dome roof.
しかし、従来の鉄筋コンクリート造による屋根がドーム状の構築物を建築するには、次の問題点がある。
（イ）木製の平面合板等を立体的に曲面上に構成することは、正確で精度の高い型枠を確保する必要があり、長い経験と高い施工技術が必要になる。
（ロ）木製やFRP製の型枠でドームの曲面上の支保工を多く配置する必要があり、ドーム内部での作業性が極端に落ちるため、人工数が嵩み、その結果、施工単価が高くなる。
（ハ）ドーム状の屋根は、勾配が緩やかに傾斜しているので、コンクリートの打設時には、バイブレーターの使用に多くの制約を受ける。
（ニ）ドーム屋根の型枠間の狭い空間にコンクリート打設をする際に多くの人工を必要とする。また、コンクリートの充填状態が型枠外からは把握しにくいため、密実なコンクリートを打設するには、打設時に多くの人員を配置する必要がある。
（ホ）木製型枠やFRP製の型枠で水平、垂直を確保する場合には、それぞれの部位での水平垂直の確認が逐一必要であり、作業が煩雑になり、施工に多くの時間を要する。
（ヘ）例えば、木製型枠でドーム状の屋根をコンクリート一体形成する場合、型枠が木製であることから軽量で作業性は良いが、打設したコンクリートの重量で木製の型枠が圧縮されて型枠同士が強く締め付けられた状態になり、コンクリート面に強く付着してしまい、脱枠をする際に型枠がバラバラになる可能性が高い。そのため、木製の型枠は再利用が難しく、その結果、コスト面で高くなる。同様の理由で、FRP製の型枠も脱枠時に破壊されてしまうことが多い。また、FRP製の型枠を木製型枠同様の強度を確保するためには、FRP自体に厚みが必要であり、その結果、コスト面でも高くなり重量も大きくなる。
However, there are the following problems associated with constructing a structure with a dome-shaped roof using conventional reinforced concrete construction.
(i) To construct a three-dimensional curved surface using flat wooden plywood, etc., requires accurate and precise formwork, which requires long experience and high construction techniques.
(b) A large number of support structures would need to be placed on the curved surface of the dome using wooden or FRP formwork, which would drastically reduce workability inside the dome and increase the number of man-hours required, resulting in a higher construction cost per unit.
(c) Since a dome-shaped roof has a gentle slope, there are many restrictions on the use of vibrators when pouring concrete.
(d) Pouring concrete into the narrow space between the formwork of the dome roof requires a lot of manpower. In addition, since it is difficult to check the concrete filling condition from outside the formwork, pouring dense concrete requires many manpower.
(e) When ensuring horizontal and vertical alignment using wooden or FRP formwork, it is necessary to check the horizontal and vertical alignment of each part one by one, which makes the work complicated and takes a lot of time for construction.
(F) For example, when a dome-shaped roof is integrally formed with concrete using a wooden formwork, the formwork is made of wood, so it is lightweight and easy to work with, but the weight of the poured concrete compresses the wooden formwork, causing it to be tightly clamped together and adhere strongly to the concrete surface, so there is a high possibility that the formwork will fall apart when it is removed. For this reason, wooden formwork is difficult to reuse, which results in high costs. For the same reason, FRP formwork is often destroyed when it is removed. Also, in order to ensure that FRP formwork has the same strength as wooden formwork, the FRP itself needs to be thick, which results in high costs and heavy weight.
本発明は、上記した問題点を解決するためになされたもので、コンクリート一体形成型のドーム状建築物の建築方法を提供することを目的とする。 The present invention was made to solve the above problems, and aims to provide a method for constructing a dome-shaped building that is integrally formed from concrete.
本発明は、居住空間を構成する円形型をなした屋根がドーム状の建築物であり、内部に居住快適性や利便性の間仕切壁等を便宜的に配するが強度補強等構造上の支柱等は皆無である。
建築物の基礎、壁、屋根は鉄筋コンクリートによる一体形成型で強度的に安全、安心で快適に生活することが可能である。
居住空間を基本として出入口、窓開口の採光を備えた開放型居住空間を提供し、リゾート宿泊施設、カフェ、レストラン、各種管理棟、はなれ、研究室、住宅等として活用できる廉価普及型建築物を提供できる。
ドーム屋根頂部には、採光を取るための天窓や、換気装置を設置できるため、快適性を高めることができる。
天窓や換気装置を取り付けるための、ドーム頂部の型枠及び支保工用具は、型枠組立と解体の際に使用し、安全に、しかも確実に重量のある屋根内型枠を解体する重要な働きをする。
前記の円形の壁面及び屋根の半球状をコンクリートで一体形成するにあたり、型枠を木材、FRP、鋼材等のいずれも選択可能であり、内壁型枠及び型枠保持機能と脱枠が容易な、屋根支保工パイプ金具、クロスバー円形直径維持パイプ、クロスパイプ支保工固定金具、壁枠斜め支保工パイプを使用することで、外枠に支保工を用いることなくコンクリート打設が可能で、施工の確実性を高めるとともに、省力化、後期の短縮化を可能にできる。
ドーム外部の壁と屋根は、断熱用塗料等を塗布することで、灼熱や風雪環境でも快適に生活ができる。
また、内部の壁と屋根は、漆喰壁を使用することで、調湿効果と防音効果を得られる。
また、本発明にかかる構築物は、暴風時には暴風シエルターとして活用することができる。
ドーム屋根左官補修や塗装及び完成後の屋根・保守点検回収塗装などでは、階段梯子で材質はパイプで手すりを設けた円形の周囲を可動できる装置を使うことで、安全に確実に施工時間を短縮できる。
The present invention is a dome-shaped building with a circular roof that defines the living space, and partition walls and the like are conveniently placed inside for the comfort and convenience of the living space, but there are no structural supports or the like for strength reinforcement.
The building's foundation, walls, and roof are made of reinforced concrete and are integrally formed, providing sufficient strength to ensure safety, security, and comfort in which to live.
To provide an open-type living space based on a living space and equipped with an entrance and windows for natural lighting, and to provide a low-cost, popular building that can be used as a resort accommodation facility, a cafe, a restaurant, various management buildings, annexes, laboratories, residences, etc.
The top of the dome roof can be fitted with a skylight to let in natural light and a ventilation system to increase comfort.
The formwork and shoring tools at the top of the dome for installing skylights and ventilation devices are used during the assembly and dismantling of the formwork, and play an important role in safely and reliably dismantling the heavy inner roof formwork.
In forming the circular walls and hemispherical roof as a single unit out of concrete, the formwork can be selected from any material, such as wood, FRP, or steel, and by using roof support pipe fittings, crossbar circular diameter maintaining pipes, cross pipe support fixing fittings, and wall frame diagonal support pipes, which have interior wall formwork and formwork retention functions and can be easily removed, concrete can be poured without using shoring for the outer frame, which increases the reliability of construction while also saving labor and shortening the later stages.
The exterior walls and roof of the dome are coated with insulating paint, making it possible to live comfortably even in scorching heat or in windy, snowy environments.
In addition, the interior walls and roof are made of plaster, which provides moisture-regulating and soundproofing effects.
Furthermore, the structure of the present invention can be used as a storm shelter during a storm.
For plastering repair and painting of dome roofs, and for roof maintenance, inspection, and recovery painting after completion, construction time can be shortened safely and reliably by using a circular device with a movable perimeter of a step ladder made of pipes and equipped with handrails.
本発明の鉄筋コンクリート造ドームの構築方法は、以上説明してきた通り次のような効果を得ることが可能となる。
（イ）従来の工事現場で型枠を組み立てて鉄筋コンクリート造ドームを構築する方法では、円滑な局面を形成するには豊富な経験と多大な労力及び高度な技術を必要としたが、本発明は、同一形状の幅小壁型枠や、幅小屋根鋼製型枠を工場で大量作成し、これを現場で順次組み立ててドームを構築する方法である。その結果、精度性、品質性、正確性、施工性、経済性が高く円滑なドーム曲面施工を容易に構築することが可能である。
（ロ）鉄筋コンクリート造のドーム鋼製型枠を採用することで強度が強く、円形屋根頂部の天窓型枠を「屋根支保工パイプ金具」と「クロスパイプ支保工固定金具」でコンクリート重量を支えることで多くの支保工が不要となり、ドーム内部での作業性が非常によくなりスムーズな施工ができる。
（ハ）ドーム屋根の緩やかな傾斜や、急な傾斜角度の困難なコンクリート打設の問題点であるが、屋根外型枠を屋根内型枠の半分程度の長さにすることで、運搬、組み立て施工が容易になることや、コンクリート打設時のバイブレーター作業も容易にすることが可能となる。屋根外型枠上のコンクリート打設後は、左官で仕上げを行う。このように密実なコンクリートを打設する施工方法として有効である。
（ニ）コンクリート型枠の水平、垂直を正確に保持するために多くの労力を必要とするが、「クロスバー円形直径維持パイプ」と「壁枠斜め支保工パイプ」方式でそれぞれの部位での水平、垂直確認作業が容易にできて、煩雑な確認作業を省略することが出来て、素早く内壁型枠を組み立てることが可能となる。
（ホ）木製型枠やＦＲＰ製型枠によるドーム状の屋根の構築物を建築する方法では、脱枠時に型枠が破壊されることが多く、型枠転用ができないので経済合理性がない。しかし、鋼製型枠を工場生産することにより幅小鋼製型枠で軽量化を図り、工事現場で組み立てることができる本発明では、転用が可能で経済性も高くなり、木製型枠やＦＲＰ製型枠の欠点を克服できる。
As described above, the method for constructing a reinforced concrete dome of the present invention can provide the following effects.
(a) In the conventional method of constructing a reinforced concrete dome by assembling formwork at the construction site, it required a wealth of experience, a great deal of effort, and advanced technology to form a smooth curved surface, but the present invention is a method of mass-producing narrow wall formwork and narrow roof steel formwork of the same shape at the factory and assembling them one by one at the site to construct a dome. As a result, it is possible to easily construct a smooth curved dome construction with high precision, quality, accuracy, workability, and economy.
(b) The use of a steel formwork for the reinforced concrete dome makes it strong, and by supporting the weight of the concrete for the skylight formwork at the top of the circular roof with "roof shoring pipe fittings" and "cross-pipe shoring fixing fittings," much shoring is unnecessary, making it much easier to work inside the dome and allowing for smooth construction.
(c) There are problems with pouring concrete for dome roofs with gentle slopes or steep slopes, but by making the outer roof formwork about half the length of the inner roof formwork, it becomes easier to transport and assemble, and it also makes it easier to use a vibrator when pouring concrete. After pouring the concrete on the outer roof formwork, the finishing touches are done by plasterers. This is an effective construction method for pouring dense concrete.
(ii) A great deal of effort is required to accurately maintain the horizontal and vertical alignment of the concrete formwork, but the "crossbar circular diameter maintaining pipe" and "wall frame diagonal support pipe" method make it easy to check the horizontal and vertical alignment of each part, eliminating the need for complicated checking procedures and enabling the interior wall formwork to be assembled quickly.
(e) In the method of constructing a dome-shaped roof structure using wooden or FRP formwork, the formwork is often destroyed when it is removed, and it is not economically rational because it cannot be reused. However, in the present invention, by producing steel formwork in a factory, it is possible to reduce weight with a narrow steel formwork and assemble it on the construction site, making it possible to reuse it and increasing the economy, and overcoming the disadvantages of wooden and FRP formwork.
図１は、ドーム頂点の中心から均等に分割した数の鋼製型枠を配した様子を示した平面図である。
内壁型枠、外壁型枠、屋根内型枠、屋根外型枠ともに施工性を考慮した。
鋼製型枠は、幅６００ｍｍ程度に小さくすることで運搬移動や組立が容易で、人力でも可能になる。
天窓部分の型枠底面にはアイボルトを溶接して、土間中心のアイボルトとチェーンで緊結して固定する。
また、アイボルトは屋根内型枠の脱枠時にチェーンブロックを取り付けることで、屋根内型枠のボルト穴にフックを掛けて脱枠することができる。
同様に４か所の屋根支保工パイプ金具の受平鉄板を溶接してあり、支保工先端に設けた平鉄板をボルトナット或いはＵクリップで固結する。
FIG. 1 is a plan view showing the arrangement of steel formwork evenly spaced from the center of the dome apex.
Workability was taken into consideration for the interior wall formwork, exterior wall formwork, interior roof formwork, and exterior roof formwork.
By reducing the width of the steel formwork to around 600 mm, it becomes easier to transport, move and assemble, and can even be done by hand.
An eye bolt is welded to the bottom of the formwork for the skylight area, and then secured in place with a chain and the eye bolt in the center of the floor.
In addition, by attaching a chain block to the eye bolt when removing the inner roof formwork, the hook can be hooked onto the bolt hole in the inner roof formwork to remove it.
Similarly, the flat iron plates to support the roof support pipe fittings in four places are welded, and the flat iron plates at the ends of the supports are secured with bolts and nuts or U-clips.

FIG. 2 shows the positions of supports and other structures used during the assembly of the dome on a plan view of the dome.
This shows the locations of cross pipe support fixing fittings, roof support pipe fittings, crossbar circular diameter maintaining pipes, wall frame diagonal support pipes, etc.
図３は、ドーム断面図にドーム組み立て時に使用する支保工等の配置状況を示したものである。 Figure 3 shows the cross-section of the dome, showing the placement of supports and other structures used during dome assembly.

図４乃至９は、図１のドーム屋根を左右方向に長くしているが、図１のドーム屋根を図１の中央横方向に切断し、図１のドーム屋根を上下方向に長くした状態の建築物にすることもできる。
4 to 9 show a building in which the dome roof of FIG. 1 is cut vertically in the center of FIG. 1 and extended in the left-right direction.
In Figures 4 to 9, the dome roof of Figure 1 is elongated in the left-right direction, but it is also possible to cut the dome roof of Figure 1 horizontally in the center of Figure 1 to create a building in which the dome roof of Figure 1 is elongated in the up-down direction.
本発明にかかるコンクリート一体形成型のドーム状建築物は、
鋼製型枠を使用してドーム頂点の中心から均等に分割した型枠部品で構成した壁用曲面の幅小型枠部品で制作した各型枠をボルトナットやＵクリップなどで緊結固定して施工する。
The dome-shaped building of the concrete integral construction type according to the present invention is
The curved width of the wall is made up of small frame parts that are divided evenly from the center of the dome apex using steel formwork, and each formwork is made by fastening and fixing with bolts, nuts, U-clips, etc.
まず、基礎土間を施工後に内壁型枠をコンクリート基礎土間面に設置した台木に乗せ、固着させて円形状に内壁型枠を確保する。
次に、壁頂点付近に「クロスバー円形直径維持パイプ」を直交に配置し、壁円形直径を確保する。
その後に、「壁枠斜め支保工パイプ」の、一方の端部を内壁型枠の頂部付近に固着させ、他方の端部を土間に固着する。
これにより（ホ）の問題点を解決できる。
First, after constructing the foundation floor, the inner wall formwork is placed on a base set on the surface of the concrete foundation floor and fixed in place to secure the inner wall formwork in a circular shape.
Next, a "crossbar circular diameter maintaining pipe" is placed perpendicularly near the apex of the wall to ensure the circular diameter of the wall.
Then, one end of the "wall frame diagonal support pipe" is fixed near the top of the inner wall formwork, and the other end is fixed to the earthen floor.
This can solve the problem (e).
鋼製型枠は、既成定尺の鋼製品で加工できるように工夫してあり、（イ）の問題点を解決できる。 The steel formwork is designed so that it can be processed using prefabricated steel products of fixed lengths, solving the problem in (a).
次に、ドーム土間の円形中心点の垂直線上に天窓用の天窓型枠を所定位置に設置し、「屋根支保工パイプ金具」で高さと中心位置を確認し設置する。
この「屋根支保工パイプ金具」の垂直方向の上、中，下段の３か所に「クロスパイプ支保工固定金具」で支保工間の間隔を維持するとともに支保工の座屈を防止する目的で設置してコンクリート重量を支える。
これにより、（ロ）の問題点を解決できる。
Next, place the skylight formwork for the skylight in the designated position on the vertical line of the circular center point of the dome floor, and then check the height and center position using the "roof support pipe fittings" before installing it.
"Cross pipe support fixing brackets" are installed at three vertical points on the "roof support pipe bracket" - the top, middle, and bottom - to maintain the spacing between the supports and prevent the supports from buckling, and to support the weight of the concrete.
This makes it possible to solve the problem (b).
次にドーム内部に設置した足場に、屋根内型枠を移動させて、天窓型枠と内壁型枠頂点の間に、分割製作した屋根内型枠をボルトナットやＵクリップ等の緊結材で固着する。
外壁型枠は、コンクリート基礎土間に台木を設置し、そこに乗せ順次円形状に並べ立て、内壁型枠に設置したセパレーターで固結する。
屋根外型枠は、屋根曲面半分ほどの長さで加工してあり、屋根内型枠とセパレーターで固結する。
屋根外型枠を屋根内型枠と同じ長さにすると、コンクリート打設の際に、コンクリートが確実に充填されているか判断が困難であるが、屋根外型枠の長さを半分にすることでコンクリート打設を容易にするとともに、バイブレーターの使用もスムーズに出来て密実な高品質のコンクリート打設を行うことができる。
これにより（ハ）及び（ニ）の問題点を解決できる。
Next, the inner roof formwork is moved to the scaffolding installed inside the dome, and the inner roof formwork, which has been made in sections, is fixed between the tops of the skylight formwork and the inner wall formwork using fastening materials such as bolts and nuts, U-clips, etc.
The exterior wall formwork is placed on a base placed on the concrete foundation floor, and the blocks are placed on top of it and arranged in a circular shape, and then solidified with separators installed on the interior wall formwork.
The outer roof formwork is cut to a length approximately half the length of the curved roof surface, and is secured to the inner roof formwork with a separator.
If the outer roof formwork is made the same length as the inner roof formwork, it is difficult to determine whether the concrete has been filled completely when pouring it, but by halving the length of the outer roof formwork, it becomes easier to pour the concrete and the vibrator can be used smoothly, allowing for dense, high-quality concrete to be poured.
This makes it possible to solve problems (c) and (d).
鋼製型枠を使用した、鉄筋コンクリート造のドーム構築物は、型枠重量が重くなるので型枠脱枠時に危険性が木製型枠等に比べて高くなる。
内壁型枠、外壁型枠、屋根外型枠は、養生期間後に容易に脱枠が可能である。
しかし、屋根内型枠の脱枠は高い位置から脱枠するので困難になる。
その際にドーム内に足場を組み、ドーム頂部の天窓型枠に溶接設置したアイボルトにチェーンブロックを設置し、屋根内型枠のボルト穴にフックをかけて脱枠時に急激に型枠が落ちないようにすることで安全に脱枠施工できるように工夫した。
Reinforced concrete dome structures that use steel formwork are more dangerous when removing the formwork because of its weight, compared to wooden formwork, etc.
The inner wall formwork, outer wall formwork, and outer roof formwork can be easily removed after the curing period.
However, removing the inner roof formwork is difficult because it must be removed from a high position.
For this, scaffolding was set up inside the dome, and a chain block was attached to an eyebolt welded to the skylight formwork at the top of the dome. A hook was then attached to the bolt hole in the formwork inside the roof to prevent the formwork from falling suddenly when it was removed, enabling safe removal of the formwork.
以上のように、本発明の鋼製型枠を使用した鉄筋コンクリート造ドーム状建築物の構築方法は、鋼製型枠工法の欠点である重量が大きい点を、型枠の幅を小さくすることで軽くし、人力で運搬組み立て施工ができるようにしたものである。鋼製型枠の持つ強度と脱枠が容易に可能で、木製やＦＲＰ製型枠の持つ弱点を克服することができる。 As described above, the method of constructing a reinforced concrete dome-shaped building using steel formwork of the present invention overcomes the drawback of the steel formwork method, which is its heavy weight, by reducing the width of the formwork, making it lighter and allowing it to be transported, assembled and constructed by hand. The strength of steel formwork and its ease of removal overcome the weaknesses of wooden and FRP formwork.
鋼製型枠は工場で製作し、各工事現場に運搬移動することが容易で現場で鉄筋コンクリート造の一体成型型ドーム構築物を構築可能である。
鋼製型枠は，規格寸法，定尺鋼材を使用して工場生産することで安全性、正確性、快適性、強度的、経済性の高い廉価普及型の鉄筋コンクリート造のドーム状構築物の構築法である。
The steel formwork is manufactured in a factory and can be easily transported to each construction site, making it possible to construct a one-piece reinforced concrete dome structure on-site.
Steel formwork is a low-cost, widespread construction method for reinforced concrete dome-shaped structures that is safe, accurate, comfortable, strong, and economical, and can be produced in factories using standardized dimensions and fixed-length steel materials.
一旦製作した鋼製型枠は、補修点検をすることで転用が可能であり、転用回数を増やすことができることで、木製型枠やＦＲＰ製型枠等と比較しても経済的効果が大きく木材等を浪費することもなくなる。
Once manufactured, steel formwork can be reused by repair and inspection, and the number of times it can be reused can be increased, which has a great economic effect compared to wooden formwork or FRP formwork, and eliminates the waste of wood, etc.
