Description
本考案は、鉄筋コンクリート造によるドーム状の構築物に関する。 The present invention relates to a dome-shaped structure made of 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。 Reinforced concrete buildings with dome-shaped roofs cannot be constructed as easily as buildings with horizontal roofs such as conventional flat roof slabs. For example, dome-shaped buildings are disclosed in Patent Documents 1 and 2, but since the entire roof of a building with a dome-shaped roof has a domed hemispherical shape, first the lower end of the dome roof is It is necessary to assemble it into a dome shape using formwork made of wooden plywood or FRP, then arrange reinforcing bars on top of it, pour concrete, and build a dome roof made of reinforced concrete.
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 in constructing a conventional reinforced concrete structure with a dome-shaped roof. (b) Configuring planar wooden plywood etc. into a three-dimensional curved surface requires accurate and highly precise formwork, which requires long experience and advanced construction techniques. (b) It is necessary to place a large number of supports on the curved surface of the dome using formwork made of wood or FRP, which greatly reduces the work efficiency inside the dome, which increases the number of manpower and, as a result, increases the construction cost. It gets expensive. (c) Since the dome-shaped roof has a gentle slope, there are many restrictions on the use of vibrators when pouring concrete. (d) Many workers are required to pour concrete into the narrow space between the forms of the dome roof. Furthermore, since it is difficult to ascertain the filling state of concrete from outside the formwork, it is necessary to deploy many people at the time of pouring concrete in order to pour dense concrete. (e) When ensuring horizontality and verticality with wooden formwork or FRP formwork, it is necessary to check the horizontality and verticality of each part one by one, which makes the work complicated and takes a lot of time. It takes. (f) For example, when forming a dome-shaped roof with concrete using wooden formwork, the formwork is made of wood and is lightweight and easy to work with, but the weight of the poured concrete compresses the wooden formwork. As a result, the formwork becomes tightly clamped together and strongly adheres to the concrete surface, and there is a high possibility that the formwork will fall apart when it is removed. Therefore, wooden formwork is difficult to reuse, resulting in high costs. For the same reason, FRP formwork is often destroyed when it is removed. Furthermore, in order to ensure that FRP formwork has the same strength as wooden formwork, the FRP itself needs to be thicker, which results in higher cost and weight.
本考案は、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を提供することを目的とする。 The present invention was made in order to solve the above-mentioned problems, and its purpose is to provide a dome-shaped building integrally formed with concrete.
本考案は、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、内枠壁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、本考案にかかる構築物は、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。 This invention is a building with a dome-shaped circular roof that constitutes the living space, and partition walls, etc. are conveniently placed inside for living comfort and convenience, but structural support such as strength reinforcement is provided. There are no such cases. The building's foundation, walls, and roof are integrally formed using reinforced concrete, making it safe, secure, and comfortable to live in. We aim to provide low-cost and popular buildings that are basically residential spaces, and that can be used as resort accommodations, cafes, restaurants, various administrative buildings, outbuildings, laboratories, residences, etc. Can be provided. A skylight to let in sunlight and a ventilation system can be installed on the top of the dome roof, increasing comfort. The formwork and supporting tools at the top of the dome for installing skylights and ventilation systems are used during formwork assembly and dismantling, and play an important role in safely and reliably dismantling heavy roof formwork. do. When integrally forming the circular wall surface and hemispherical shape of the roof with concrete, the formwork can be selected from wood, FRP, steel, etc., and the inner frame wall and formwork retaining function and the frame can be easily removed. By using roof shoring pipe fittings, crossbar circular diameter maintaining pipes, cross pipe shoring fixing fittings, and wall frame diagonal shoring pipes, concrete can be placed without using shoring for the outer frame, making construction easier. In addition to increasing reliability, it is possible to save labor and shorten the later stages. The exterior walls and roof of the dome are coated with heat-insulating paint, allowing for comfortable living even in scorching heat and windy, snowy environments. In addition, by using plaster walls for the interior walls and roof, you can achieve humidity control and soundproofing effects. Additionally, the structure according to the present invention can be used as a storm shelter during storms. For dome roof plastering repair, painting, roof maintenance inspection collection painting after completion, etc., we use a device that can move around a circular area with a handrail made of a stair ladder and made of pipe to safely and reliably shorten the construction time. can.
本考案の鉄筋コンクリート造ドーム状建築物は、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、本考案は、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、円形屋根頂部の円形型枠を「ドーム内屋根支保工パイプ金具」と「クロスバー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、外屋根型枠を内屋根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。外屋根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「壁型枠斜め支保工固定金具」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考案では、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 explained above, the reinforced concrete dome-shaped building of the present invention can achieve the following effects. (b) The conventional method of building a reinforced concrete dome by assembling formwork at the construction site required a wealth of experience, a great deal of labor, and advanced technology to form a smooth surface. This is a method in which a large number of narrow wall formwork and narrow roof steel formwork of the same shape are produced in a factory, and then assembled one after another on-site to construct a dome. As a result, it is possible to easily construct a smooth dome curved surface with high precision, quality, precision, workability, and economy. (b) The dome is made of reinforced concrete and has strong strength due to the use of steel formwork, and the circular formwork at the top of the circular roof is made of ``dome roof support pipe fittings'' and ``crossbar pipe support fixing fittings'' to prevent concrete weight. Supporting the dome eliminates the need for a lot of shoring, making work inside the dome much easier and allowing for smooth construction. (c) Concerning the difficulty of pouring concrete due to the gentle slope of the dome roof or the steep angle of slope, the outer roof formwork can be made about half the length of the inner roof formwork, making transportation easier. This makes assembly work easier, and it also makes it easier to use a vibrator when pouring concrete. After pouring concrete on the outside roof formwork, finish with plastering. This is an effective construction method for placing concrete in a dense manner. (d) Although it requires a lot of effort to accurately maintain the horizontal and vertical orientation of concrete formwork, the "crossbar circular diameter maintenance pipe" and "wall formwork diagonal support fixing brackets" methods can be used to Horizontal and vertical confirmation work can be easily performed, complicated confirmation work can be omitted, and inner wall formwork can be assembled quickly. (E) Methods of constructing dome-shaped roof structures using wooden formwork or FRP formwork are not economically rational because the formwork is often destroyed when the formwork is removed and the formwork cannot be reused. However, by manufacturing steel formwork in a factory, the weight of the steel formwork is reduced, and it can be assembled at the construction site.This invention allows for diversion and is highly economical, allowing wooden formwork or FRP to be used. It can overcome the drawbacks of 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か所のドーム内部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 a state in which a number of equally divided steel formworks are arranged from the center of the apex of the dome. Workability was considered for both internal wall formwork, external wall formwork, internal roof formwork, and external roof formwork. By making the steel formwork as small as 600mm in width, it is easy to transport and assemble, even by hand. An eye bolt will be welded to the bottom of the formwork for the skylight section, and it will be secured by tightening it with a chain to the eye bolt in the center of the dirt floor. In addition, by attaching a chain block to the eye bolts when removing the roof formwork, it is possible to remove the formwork by hooking the hook into the bolt hole of the roof formwork. Similarly, the flat iron plates of the dome internal roof shoring pipe fittings are welded together at four locations, and the flat iron plates provided at the tips of the shorings are fixed with bolts and nuts or U-clips.
図２は、ドーム平面図上にドーム組み立ての際に使用する支保工等の配置位置を示すものである。クロスパイプ支保工固定金具の配置位置、ドーム屋根支保工パイプ金具の配置、クロスバー円形直径維持パイプ、壁枠斜め支保工パイプ等の配置地を示す。 FIG. 2 shows, on a plan view of the dome, the placement positions of supports and the like used when assembling the dome. The locations of cross pipe support fixing fittings, dome roof support pipe fittings, crossbar circular diameter maintenance pipes, wall frame diagonal support pipes, etc. are shown.
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。 FIG. 3 is a sectional view of the dome showing the arrangement of supports and the like used when assembling the dome.
図４乃至９は、図１のドーム屋根を図１の中央縦方向に切断し、図１のドーム屋根を左右方向に長くした状態の建築物を示すものである。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 in the vertical direction at the center of FIG. 1, and the dome roof of FIG. 1 is lengthened in the left-right direction. 4 to 9 show that the dome roof in Figure 1 is lengthened in the horizontal direction, but the dome roof in Figure 1 is cut in the horizontal direction at the center of Figure 1, and the dome roof in Figure 1 is lengthened in the vertical direction. It can also be turned into a building.
本考案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 concrete-integrated dome-shaped building according to the present invention uses steel formwork and is made of small-sized frame parts with a curved surface for walls, which is made up of formwork parts equally divided from the center of the dome apex. Construction is carried out by fastening the formwork with bolts and nuts or U-clips.
まず、基礎土間を施工後に壁内枠をコンクリート基礎土間面に設置した台木に乗せ、固着させて円形状の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、クロスパイプバーで壁円形直径を確保する。その後に、「壁型枠斜め支保工固定金具」で内壁型枠の頂部付近に固着させ、パイプ一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 earthen floor, the inner wall frame is placed on a rootstock installed on the concrete foundation earthen floor surface and fixed to secure a circular inner wall formwork. Next, a ``cross bar circular diameter maintaining pipe'' is placed orthogonally near the apex of the wall, and the wall circular diameter is maintained with the cross pipe bar. After that, fix it near the top of the inner wall formwork using the "wall formwork diagonal shoring fixing fittings" and fix one end of the pipe to the dirt floor. This allows problem (e) to be solved.
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 devised so that it can be processed using pre-made steel products of a certain length, which solves the problem (a).
次に、ドーム土間の円形中心点の垂直線上に天窓用の円形状型枠を所定位置に設置し、「垂直用支保工用具」で高さと中心位置を確認し設置する。この「垂直用支保工金具」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, install the circular formwork for the skylight in a predetermined position on the vertical line of the circular center point of the dome's earthen floor, and check the height and center position using the ``vertical shoring tool'' before installing. "Cross pipe shoring fixing metal fittings" are installed at the top, middle, and bottom of this "vertical shoring metal fitting" in the vertical direction to maintain the spacing between the shoring pieces and to prevent buckling of the shoring pieces. Installed to support the weight of concrete. This makes it possible to solve problem (b).
次にドーム内部に設置した足場に屋根曲面型枠を移動して、円形状型枠と壁型枠頂点に、分割製作した屋根用ドーム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。外屋根型枠は、屋根曲面半分ほどの長さで加工してあり、屋根内枠とセパレーターで固結する。屋根外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, move the roof curved formwork to the scaffolding installed inside the dome, and fix the separately produced roof dome formwork to the apex of the circular formwork and wall formwork with fastening materials such as bolts and nuts or U-clips. . For the external wall formwork, rootstocks are installed on the concrete foundation, and the blocks are placed on top of the rootstocks and arranged in a circular shape one after another, and then solidified with separators installed on the internal wall formwork. The outer roof formwork is machined to a length that is approximately half the length of the curved roof surface, and is fixed to the inner roof frame with a separator. If the outer roof frame is made the same length as the inner roof formwork, it will be difficult to judge whether the concrete is filled properly during concrete pouring, but by cutting the length of the outer roof formwork in half, the concrete In addition to making pouring easier, the vibrator can also be used smoothly, allowing for precise, high-quality concrete pouring. 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。ドーム内壁枠、外壁枠、外屋根枠は養生期間後に容易に脱枠が可能である。しかし、内屋根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、ドーム頂部の円形状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 using steel formwork are heavier and therefore more dangerous when the formwork is removed than wooden formwork. The dome inner wall frame, outer wall frame, and outer roof frame 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. At that time, we set up scaffolding inside the dome, installed chain blocks on eye bolts welded to the circular formwork at the top of the dome, and hooked them to the bolt holes in the formwork inside the roof, causing the formwork to suddenly fall when the formwork was removed. We devised a way to safely remove the frame by preventing this from occurring.
以上のように、本考案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 disadvantage of the steel formwork method, which is the large weight, by reducing the width of the formwork. It is lightweight and can be transported, assembled and constructed by hand. It has the strength of steel formwork and can be easily removed, and can 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 method of constructing dome-shaped structures made of reinforced concrete that is safe, accurate, comfortable, strong, and economical, and is inexpensive and popular because it is manufactured in a factory using standard dimensions and length steel materials. It is.
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 repairing and inspecting it, and by increasing the number of times it can be reused, it has a greater economic effect compared to wooden formwork or FRP formwork, etc. No more wasting money etc.
