Description

この発明は、外壁用のコンクリート型枠に関するもので、室外側の外枠を断熱材をかねるものとし外断熱施工の容易化、型枠の取り外し作業を不用とし、室内側となる内枠は施工後取り外しコンクリートの打設状況を確認できるようにし、取り外した後は繰り返し使用可能としたものである。   The present invention relates to a concrete mold for an outer wall, the outer frame on the outdoor side also serves as a heat insulating material, facilitates the heat insulation work, eliminates the work of removing the mold, and the inner frame on the indoor side is constructed. After removing the concrete, it can be used repeatedly after it is removed.

従来、コンクリート打設用のコンクリート型枠は、内外に対峙させる合板製型枠にて構成するものが多く、数回乃至１０回程度の使い回しはできるものの、その後には解体廃棄処分をしていた。
そのために、金属製の型枠も提案され実際に用いられているが、重量が嵩み取り扱いに不便であった。
プラスチックの型枠も提案されているが、板厚が足りないと、コンクリート打設時に耐えられず、変形、破損が生じることがあった。 Conventionally, the concrete formwork for placing concrete is often composed of a plywood formwork facing inside and outside, and although it can be used several times to 10 times, it has been dismantled and discarded after that. It was.
For this reason, metal molds have been proposed and actually used, but they are heavy and inconvenient to handle.
Plastic formwork has also been proposed, but if the plate thickness is insufficient, it may not be able to withstand concrete placement and may be deformed or damaged.

一般的にはコンクリート壁を養生固化した後にコンクリート内外壁に沿わせて配置される断熱材そのものをコンクリート型枠とするようにした技術が、特許文献１に提示するよう提案され、工期の短縮、コストダウンに資するとしている。
特開平２ー３４６５３６ In general, a technique in which a heat insulating material arranged along the inner and outer walls of a concrete after curing and solidifying a concrete wall is used as a concrete form is proposed to be presented in Patent Document 1, shortening the work period, It is supposed to contribute to cost reduction.
JP-A-2-346536

従来の特許文献１に提示する手段では、発泡樹脂製の断熱材が内外の型枠となり、コンクリート打設、養生、硬化後もそのまま残置されるので、コンクリートの打設後の仕上がり具合を確認できず、経験不足による施工不良が隠蔽されてしまう欠点を備えていた。   With the means presented in the conventional patent document 1, the heat insulating material made of foamed resin becomes the formwork inside and outside, and is left as it is after placing, curing, and curing the concrete, so that the finish after placing the concrete can be confirmed. However, it had the disadvantage that construction defects due to lack of experience were concealed.

そこで、この発明では、快適な生活環境を齎す外断熱の外壁を、合板を使わずに工期の短縮、コストダウンをもってなしうるようにしたもので、しかも、コンクリートの打設面の確認ができるように、内側の型枠を解体、繰り返し使用できるようにしたものである。   Therefore, according to the present invention, the outer wall of the outer heat insulation, which gives a comfortable living environment, can be made with a shortened construction period and cost reduction without using plywood, and the concrete placement surface can be confirmed. In addition, the inner formwork can be disassembled and used repeatedly.

この発明はこのような課題を解決するためのもので、請求項１の外壁用のコンクリート型枠は、プラスチック製の複数の連結具に発泡ポリスチレン板の側縁を順次嵌め込んで構成した外枠と、プラスチック製の半透明素材から構成した中空状のパネルを順次繋げるようにして構成した内枠とからなり、外枠はそのまま外断熱材とし、内枠は解体して繰り返し使えるようにしたことを特徴とする。   The present invention is to solve such problems, and the concrete form for an outer wall according to claim 1 is formed by sequentially fitting side edges of a polystyrene foam plate into a plurality of plastic couplers. And an inner frame constructed by sequentially connecting hollow panels made of plastic translucent material. The outer frame is used as an external heat insulating material, and the inner frame is disassembled so that it can be used repeatedly. It is characterized by.

請求項２の外壁用のコンクリート型枠は、縦長方形の発泡ポリスチレン板の隣り合う長手方向の側縁を受け入れ、セパレータの掛孔を所定間隔で穿った縦縁を備えた断面略土の字状をなすプラスチック製の複数の連結具に発泡ポリスチレン板の側縁を順次嵌め込んで構成した外枠と、一端に鉤状の引っ掛け片を、他端部にスロットを穿ったセパレータと、堰板部と向き合う背面部の間に補強板を介し、側板部は堰板部より内側としかつ背面部より突き出すようにして全体は中空状のパネルとし、堰板部の両側縁にはセパレータの厚みの半分を受け入れる凹部を列設し、側板部の突出した箇所にはセパレータのスロットに対応するスロットを穿つようにしたプラスチック製の半透明素材からなる内枠と、外枠と内枠及び内枠同士を繋ぐために隣り合う内枠のスロットにセパレータのスロットを挟んで刺し込む楔金具及びこの楔金具の長穴に刺し込んで固定する楔金具とからなるものである。   The concrete form for an outer wall according to claim 2 is a substantially earth-shaped cross section having a vertical edge which receives side edges in the longitudinal direction adjacent to each other in a vertical rectangular foamed polystyrene plate and has holes for separators formed at predetermined intervals. An outer frame formed by sequentially fitting side edges of a polystyrene foam plate to a plurality of plastic couplers, a separator having a hook-like hook piece at one end, and a slot at the other end, and a dam plate portion Through the reinforcing plate between the facing back parts, the side plate part is inside the weir plate part and protrudes from the back part, so that the whole is a hollow panel, and on both side edges of the weir plate part is half the thickness of the separator The inner frame made of a plastic translucent material that has a slot corresponding to the slot of the separator at the protruding portion of the side plate portion, and the outer frame, the inner frame, and the inner frames Next to connect It is made of a wedge fitting for fixing by pierces the long hole wedge bracket and the wedge bracket plugging across the separator slot in the inner frame of the slot fit.

この発明は以上のような構成からなるもので、請求項１の発明では、快適な生活環境を齎す外断熱のコンクリート壁を経済的に提供できることになる。すなわち外枠を基本的には発泡ポリスチレン板として、型枠と断熱材を兼ねるようにし、しかもこの外枠はプラスチック製の複数の連結具により繋ぐようにしているので強度を保つことができる。   The present invention is configured as described above. According to the first aspect of the present invention, it is possible to economically provide an external heat insulating concrete wall that gives a comfortable living environment. That is, the outer frame is basically made of a polystyrene foam plate so as to serve both as a mold and a heat insulating material, and since the outer frame is connected by a plurality of plastic couplers, the strength can be maintained.

また、一般的な合板によるコンクリート型枠では、その素材として熱帯雨林の森林資源を用いることが多いが、この発明ではその伐採による減少を避けることができることになる。
外枠及び内枠を樹脂成形品としたのであるが、内枠を半透明部材としたので、コンクリートを打設しながら充填状況を確認できるのである。しかも、内枠はコンクリートの養生、硬化後に解体して繰り返し用いるので、コンクリート壁の仕上がり具合を視認することもでき、工事不良を見過ごすこともない。 Moreover, in general concrete forms made of plywood, the forest resources of the rainforest are often used as the material, but in the present invention, reduction due to the cutting can be avoided.
Although the outer frame and the inner frame are resin molded products, since the inner frame is a translucent member, the filling state can be confirmed while placing concrete. Moreover, since the inner frame is repeatedly disassembled and used after curing and hardening of the concrete, the finish of the concrete wall can be visually confirmed, and construction defects are not overlooked.

請求項２の発明では、セパレータを外枠を構成する連結部材に引っ掛けることで組み付けられることになるので構成が簡単となり部品点数の減少、作業の省力化が可能となったのである。すなわち、従来のセパレータはコンクリート型枠を貫通させるので、内外で作業をしなくてはならなかったが、内側のみで作業ができることになるのである。
また、楔金具を用いてセパレータのスロットを内枠を構成するパネルのスロットに挟んで止め、かつ、この楔金具のスロットに楔金具を打ち込むようにしたので、回転させるねじを用いないので作業がきわめて簡単となる。 In the invention of claim 2, since the separator is assembled by being hooked on the connecting member constituting the outer frame, the configuration is simplified, and the number of parts can be reduced and the labor can be saved. That is, since the conventional separator penetrates the concrete formwork, the work must be done inside and outside, but the work can be done only inside.
Also, since the separator slot is sandwiched between the slot of the panel constituting the inner frame by using the wedge fitting and the wedge fitting is driven into the slot of the wedge fitting, the work is not performed because the rotating screw is not used. It becomes very simple.

以下、図面に示すこの発明の実施の形態に即して説明する。
図１は、この発明にかかわるコンクリート型枠の概要の断面図である。
コンクリート型枠１は、概略外部側の外枠２と内部側の内枠３とからなり、これら外枠２と内枠３を所定の間隔、すなわちコンクリート壁の厚み分離して対峙させるためのセパレータ４及びこれらを結合連結する楔金具５とからなるものである。６は外枠２に横方向に渡したバタ材であり、７は内枠３に渡したバタ材であり、８はバタ材７から床面に至るように配置するターンバックルからなる支保材である。 Hereinafter, the present invention will be described with reference to the embodiments shown in the drawings.
FIG. 1 is a schematic sectional view of a concrete formwork according to the present invention.
The concrete mold 1 is composed of an outer frame 2 on the outer side and an inner frame 3 on the inner side, and the outer frame 2 and the inner frame 3 are opposed to each other with a predetermined interval, that is, with a concrete wall thickness separated. 4 and a wedge fitting 5 for connecting and connecting them. 6 is a butter material that is passed to the outer frame 2 in the lateral direction, 7 is a butter material that is passed to the inner frame 3, and 8 is a support material made of a turnbuckle arranged from the butter material 7 to the floor surface. is there.

外枠２は、図２に示すように縦長方形の発泡ポリスチレン板（ＥＰＳ板）２１を多数のプラスチック製の連結具２２にて縦方向に並べて形成するものである。
発泡ポリスチレン板２１は発泡倍率４０倍程度の比較的硬質なものとし、厚みは６５ｍｍ、幅は３００ｍｍ弱とする。ＪＩＳＡ９５１１で規定されている難燃性試験で「火源を後退させると３秒以内に火が消える」グレードを用い断熱材を兼ねるようにする。
連結具２２は、プラスチックの成形品からなるもので、発泡ポリスチレン板２１の隣り合う長手方向の側縁を受け入れる断面Ｈ形板２２１と、セパレータ４の掛孔２２２ａを所定間隔で穿った縦縁２２２を備え全体として断面略土の字状としたものである。尚、縦縁２２２は掛孔２２２ａを設ける箇所のみ断続的に設けるようにしても良い。
組み付けた状態で高さは２８５０ｍｍで、連結具２２同士は中央で３００ｍｍ間隔で配置されるようにする。平坦面である地上で組み付けてから、地中に形成した土台上に建て込むようにする。このとき必要に応じてバタ材６にて外側から支えるようにする。 As shown in FIG. 2, the outer frame 2 is formed by vertically arranging vertical rectangular expanded polystyrene plates (EPS plates) 21 with a number of plastic couplers 22.
The expanded polystyrene plate 21 is relatively hard with an expansion ratio of about 40 times, has a thickness of 65 mm, and a width of less than 300 mm. In the flame retardancy test stipulated in JIS A9511, a grade that “fire goes out within 3 seconds when the fire source is moved backward” is used as a heat insulating material.
The connector 22 is made of a plastic molded product, and has a cross-sectional H-shaped plate 221 that accepts adjacent side edges in the longitudinal direction of the expanded polystyrene plate 21 and a vertical edge 222 that has holes 222a formed in the separator 4 at predetermined intervals. As a whole, the cross section has a substantially earth-shaped cross section. In addition, you may make it provide the vertical edge 222 intermittently only in the location which provides the hook hole 222a.
In the assembled state, the height is 2850 mm, and the connectors 22 are arranged at intervals of 300 mm in the center. After assembling on the ground, which is a flat surface, it is built on the foundation formed in the ground. At this time, it is supported from the outside by the butterfly material 6 as necessary.

内枠３は、ポリプロピレン樹脂（ＰＰ）や塩化ビニール樹脂（ＰＶＣ）などの再生プラスチックを素材として押し出し成形により製作され、透明素材或いは半透明素材とすることが望ましく、縦長方形状の中空状のパネル３ａを順次繋げるものとする。パネル３ａは、高さは２７００ｍｍ、幅は３００ｍｍ、厚みは５５ｍｍとする。
パネル３ａは、堰板部３１と向き合う背面部３２の間に補強板３３を介し、側板部３４は堰板部３１より内側としかつ背面部３２より突き出すようにして全体は中空状として強度を保つようにしている。
堰板部３１の両側縁にはセパレータ４の厚みの半分を受け入れる凹部３１１を列設し、側板部３４の突出した箇所にはセパレータ４のスロット４２に対応するスロット３４１を穿つようにしている。 The inner frame 3 is manufactured by extrusion molding using recycled plastic such as polypropylene resin (PP) or vinyl chloride resin (PVC) as a raw material, and is preferably a transparent material or a translucent material. 3a are connected sequentially. The panel 3a has a height of 2700 mm, a width of 300 mm, and a thickness of 55 mm.
The panel 3a is provided with a reinforcing plate 33 between a back surface portion 32 facing the dam plate portion 31 and the side plate portion 34 is located inside the dam plate portion 31 and protrudes from the back surface portion 32, so that the entire panel 3a is hollow and maintains its strength. I am doing so.
Concave portions 311 for receiving half of the thickness of the separator 4 are arranged on both side edges of the dam plate portion 31, and a slot 341 corresponding to the slot 42 of the separator 4 is formed in a protruding portion of the side plate portion 34.

複数のパネル３ａを並べると堰板部３１の側端縁が当接して広い堰板を構成し、隣り合う二つのパネル３ａ、３ａの凹部３１１、３１１の当接箇所にセパレータ４の貫通孔を構成することになる。
図示しないが、この貫通孔にはセパレータ４と一体なコーンにて塞ぐようにして打設することでコンクリート成分がしみださないようにしても良い。
側板部３４を背面部３２より突出させたのは、セパレータ４を介して外枠２、内枠３を一体にするとともに並列させるパネル３ａ、３ａ同士を順次繋げるための手段としてのスロット３４１を設けるためである。 When a plurality of panels 3a are arranged, the side edges of the dam plate portion 31 come into contact with each other to form a wide dam plate, and the through holes of the separator 4 are formed at the contact positions of the recesses 311 and 311 of the two adjacent panels 3a and 3a. Will be composed.
Although not shown, the concrete component may be prevented from oozing out by being placed in this through hole so as to be closed with a cone integral with the separator 4.
The side plate portion 34 is protruded from the back surface portion 32 by providing a slot 341 as a means for sequentially connecting the panels 3a and 3a, which integrate the outer frame 2 and the inner frame 3 together with the separator 4 therebetween. Because.

図４に示すセパレータ４は、短冊状の金属板にて構成されるもので、一端を鉤状に屈曲させた引っ掛け片４１を、他端部にスロット４２を穿つようにしたものである。
連結具２２の掛孔２２２ａに引っ掛け片４１を差込むようにする。図５参照
側端縁から向き合うように設けた切込み４３は、コンクリートの養生硬化後に内枠３を除去すると、コンクリート壁から突出するセパレータ４のスロット４２を含む一端部を叩き落す際の折れ目となるものである。 The separator 4 shown in FIG. 4 is composed of a strip-shaped metal plate, and has a hooking piece 41 bent at one end in a hook shape and a slot 42 at the other end.
The hook piece 41 is inserted into the hook hole 222 a of the connector 22. See FIG. 5. The notch 43 provided so as to face the side edge is a fold when the inner frame 3 is removed after curing the concrete and when one end including the slot 42 of the separator 4 protruding from the concrete wall is knocked down. It will be.

楔金具５、５は、図６ａに示すように平板状をなすもので、幅広の頭部５１からスロット５２を穿った本体部５３及び尖端部５４を金属板を打ち抜きなどにより構成するものである。スロット５２の先に穿った丸穴５５は、一対の楔金具５、５は同時に使うので、図示しない鎖や紐でつないでおくためのものである。   As shown in FIG. 6a, the wedge brackets 5 and 5 are formed in a flat plate shape, and the main body portion 53 and the pointed end portion 54 having the slot 52 formed in the wide head portion 51 are formed by punching a metal plate or the like. . A round hole 55 formed at the tip of the slot 52 is used for connecting a pair of wedges 5 and 5 at the same time.

外枠２と内枠３及び内枠３を構成するパネル３ａ，３ａ同士を繋ぐために、隣り合うパネル３ａのスロット３４１にセパレータ４のスロット４２を挟んで楔金具５を横方向に刺し込み、このまず刺し込んだ楔金具５の上向きのスロット５２にもう一方の楔金具５を上から刺し込み頭部５１が側板部３４の内面に圧接することになり固定される。楔金具５、５は木槌乃至かなづちなどで叩き込めば良い。   In order to connect the outer frame 2, the inner frame 3, and the panels 3 a, 3 a constituting the inner frame 3, the wedge metal fitting 5 is inserted horizontally in the slot 341 of the adjacent panel 3 a with the slot 42 of the separator 4 interposed therebetween, First, the other wedge fitting 5 is inserted from above into the upward slot 52 of the wedge fitting 5 that is inserted, and the head 51 is pressed against the inner surface of the side plate portion 34 and fixed. The wedge brackets 5 and 5 may be struck with a wooden mallet or a kanazuki.

次に、この発明にかかわるコンクリート型枠１の組み立てについて説明する。
まず、広い床面に発泡ポリスチレン板２１，２１及びプラスチック製の連結具２２を並べ、順次発泡ポリスチレン板２１の側縁を連結具２２に嵌め込んで所望の外枠２を形成する。このとき連結具２２乃至発泡ポリスチレン板２１の側縁にシーリング材を塗布することにより抜け落ちないようにすることが望ましい。 Next, the assembly of the concrete formwork 1 according to the present invention will be described.
First, the expanded polystyrene plates 21 and 21 and the plastic connector 22 are arranged on a wide floor surface, and the desired outer frame 2 is formed by sequentially fitting the side edges of the expanded polystyrene plate 21 into the connector 22. At this time, it is desirable to prevent the connector 22 or the expanded polystyrene plate 21 from falling off by applying a sealing material to the side edges.

次に、所望の箇所に外枠２を建て込むようにする。バタ材６にて外枠２が波打たないようにする。そして、セパレータ４の引っ掛け片４１を連結具２２の掛孔２２２ａに差込み、セパレータ４，４を外枠２と直交するように配置する。
更に、内枠３を構成するパネル３ａ、３ａの堰板部３１の両側縁の凹部３１１，３１１にセパレータ４を嵌め込むようにして建て込む。すると隣り合うパネル３ａ、３ａのスロット３４１，３４１とセパレータ４のスロット４２は対応して横方向矩形の貫通孔となる。ここに、楔金具５を刺し込み、この楔金具５のスロット５２を露出させる。もう一方の楔金具５を露出したスロット５２に上から刺し込み頭部５１が側板部３４に圧接するようにする。刺し込ませるには木槌などで叩き込むようにする。 Next, the outer frame 2 is built in a desired location. The outer frame 2 is prevented from wavy by the butter material 6. Then, the hooking piece 41 of the separator 4 is inserted into the hooking hole 222 a of the connector 22, and the separators 4 and 4 are arranged so as to be orthogonal to the outer frame 2.
Further, the separator 4 is built in the recesses 311 and 311 on both side edges of the barrier plate 31 of the panels 3a and 3a constituting the inner frame 3. Then, the slots 341 and 341 of the adjacent panels 3a and 3a and the slot 42 of the separator 4 are correspondingly rectangular through holes. The wedge metal 5 is inserted here, and the slot 52 of the wedge metal 5 is exposed. The other wedge fitting 5 is inserted into the exposed slot 52 from above so that the head 51 is pressed against the side plate 34. Use a wooden mallet to stab them.

続いて、角パイプ乃至角材よりなるバタ材７にて内枠３の波うちを押さえ、さらに支保材８を必要数床面とバタ材７に渡してコンクリート型枠１の垂直状態を保つようにする。尚、外枠２及び内枠３の間には図示しないが、鉄筋が配置される。
このようにしてコンクリート型枠１の組み立てが終わってからコンクリートを上から打設する。このとき内枠３が半透明体であるので、コンクリートの充填状況を確認することができる。所要期間養生した後に強度確認してから支保材８、バタ材７を外し、楔金具５、５を尖端から木槌などで叩いて抜き、内枠３を構成するパネル３ａを順次コンクリート壁面と水平に移動させて剥がす。セパレータ４のスロット４２を含む先端はコンクリート壁面から突出しているので、金槌で叩いて切込み４３から落とすようにする。
外枠２はバタ材６を外すのみでそのままの残置する。外枠２の発泡ポリスチレン板２１はコンクリートに付着しやすい傾向があるのでコンクリート壁面と一体となりそのままで外断熱材となる。 Subsequently, the wave of the inner frame 3 is pressed by the butter material 7 made of square pipe or square material, and the support material 8 is passed to the floor surface and the butter material 7 to keep the concrete formwork 1 vertical. To do. Although not shown, a reinforcing bar is disposed between the outer frame 2 and the inner frame 3.
In this way, the concrete is cast from above after the assembly of the concrete formwork 1 is completed. At this time, since the inner frame 3 is a translucent body, it is possible to confirm the concrete filling state. After checking the strength after curing for the required period, remove the support material 8 and the butter material 7, remove the wedge brackets 5, 5 by tapping them with a wooden mallet etc. from the pointed ends, and sequentially place the panel 3 a constituting the inner frame 3 horizontally with the concrete wall surface. Move to and peel off. Since the tip including the slot 42 of the separator 4 protrudes from the concrete wall surface, it is struck with a hammer and dropped from the notch 43.
The outer frame 2 is left as it is only by removing the butter material 6. Since the expanded polystyrene plate 21 of the outer frame 2 tends to adhere to concrete, it becomes an outer heat insulating material as it is integrated with the concrete wall surface.

コンクリート壁の外側に断熱材が一体に構成されるが、そのままでは耐候性に欠けるので、モルタルを塗布したり、外壁用タイル材にて被覆したり、金属その他各種素材のサイディング材を取り付けるようにする。
同様に、コンクリート壁の内側には各種素材の内装材をもって覆うようにする。 Insulation material is integrally formed on the outside of the concrete wall, but as it is not weather resistant as it is, apply mortar, coat it with tiles for outer walls, attach siding materials of metal and other materials To do.
Similarly, the interior of the concrete wall is covered with various interior materials.

図８、図９はＬ形のコーナーのコンクリート型枠１を示すもので、それぞれ概略平面図及び斜視図である。
コーナーの場合の連結具２２は、角筒柱２２４を介して発泡ポリスチレン板２１の側縁を受け入れる縦溝２２５を一体に形成してなるものである。縦縁２２２は備えないものとする。角筒柱２２４内には図示しないが角柱状の発泡ポリスチレンを挿入する。
外枠２の出隅の外側に平面及び断面Ｌ形をなす横バタ金具６１をあてがい、図示しないビスにて連結具２２にねじ込むようにすることではらみを防ぐようにする。コーナーの入り隅を構成するパネル３ｂは平面Ｌ形をなすものとする。 8 and 9 show an L-shaped corner concrete formwork 1, which are a schematic plan view and a perspective view, respectively.
The connecting tool 22 in the case of a corner is formed by integrally forming a longitudinal groove 225 that receives a side edge of the expanded polystyrene plate 21 via a square cylindrical column 224. The vertical edge 222 is not provided. Although not shown in the figure, prismatic expanded polystyrene is inserted into the prismatic cylinder 224.
A horizontal butterfly fitting 61 having a flat surface and an L-shaped cross section is assigned to the outside of the outer corner of the outer frame 2 and screwed into the connector 22 with a screw (not shown) to prevent jamming. The panel 3b constituting the corner of the corner is assumed to have a plane L shape.

コンクリート外壁がＴ型をなす場合も、図１０に示すように平面Ｌ形のパネル３ｂをもって方形のパネル３ａに繋げ内枠３を構成する。
なお、請求項１の発明において、内枠３を構成するパネル３ａを横方向に接合し、繋げるのには図示の実施の形態に限定されず、従来採用されている手段をもってなすこともできる。 Even when the concrete outer wall is T-shaped, as shown in FIG. 10, the inner frame 3 is formed by connecting the flat panel 3b to the rectangular panel 3a.
In addition, in invention of Claim 1, it is not limited to embodiment of illustration to join the panel 3a which comprises the inner frame 3 to a horizontal direction, and it can also be made with the means employ | adopted conventionally.
