Description
【０００１】
【産業上の利用分野】
本発明は、コンクリ−ト型枠、及びコンクリ−ト型枠とコンクリ−トとが一体になった壁構造物に関する。
【０００２】
【従来の技術】
近年、住宅を高断熱化、高気密化して住宅の規格を上げるために、また、施工を容易にして住宅建築価格の大幅なコストダウンを計る目的で、ツ−バイフォ−型等の木造住宅の布基礎や、鉄筋コンクリ−ト建物の壁を形成する為の、合成樹脂成形体組合せ式コンクリ−ト型枠と、その型枠内に配筋された鉄筋と、その型枠内に打たれ固められたコンクリ−トからなる建物用の壁が注目され、その普及が大いに期待されている。
【０００３】
そのような合成樹脂成形体の組合せ式コンクリ−ト型枠には、大別すると、例えば特開平６−１２９０９９号に記載されるように、縁に接合端として凹凸構造を有し、接合端から中心に向かってのびるＴ型断面の溝を有している発泡ポリスチレン等の合成樹脂製のサイドパネル部材と、向かい合うサイドパネル部材同士の間隔を固定する為に、そのサイドパネルの中に差込まれるスペ−サ−部材（このようなスペ−サ−部材は、機能的には引張り力を受けるので引張り材であるが、本明細書でもスペ−サ−部材と記載する）とを組立てて、型枠を形成するものや、例えば特開平６−３４６５３６号に記載されるように、向かい合ったパネル部材の間を橋渡しする橋渡し部材がパネル部材に鋳込まれて一体の建築物構成要素をなしているものを積み重ねて形成するものがある。
【０００４】
【発明が解決しようとする課題】
しかし、コンクリ−トが打たれる型枠にはコンクリ−トの液圧がかかって、スペ−サ−部材にはかなりの引張り力が加わる。上に述べた従来技術の型枠材料に用いられているスペ−サ−部材は、型枠の相対位置を安定的に固定する能力に乏しかった。したがって、パネル部材の単位面積あたりのスペ−サ−部材の数を多くせざるを得ず、その分コンクリ−トが少なくなってしまうという欠点を有していた。
【０００５】
【課題を解決する手段】
本発明者は、上記の問題を解決すべく鋭意研究した結果、スペ−サ−部材の端プレ−ト部のプレ−トを２枚以上にすると上記の問題点が解決出来ることを発見し、本発明を完成させた。
【０００６】
即ち、本発明の一つは、
（ａ）イ）複数個を繋ぎあわせるために端面を互いに相補的な形状とした、コンクリート型枠の対向面を形成するための成形体、
ロ）該対向面間の間隔を保つ為に使用され、一端に２枚以上のプレートを含む端プレート部と、端プレート部を両端としてその間に存在するウェブ部とからなる一体のスペーサー部材、
を含んでおり、該スペーサー部材の端プレート部が該成形体中に鋳込まれている、すなわち、該成形体中に一体的に同時成形されて埋め込まれているか、又は該スペーサー部材の端プレート部の２枚以上のプレートを該成形体に挿入する為に、該成形体が、該端プレート部の断面に対応する断面形状の、該端面から中心方向に向かう溝穴を有している、
ことを特徴とするコンクリート用型枠材料で形成された型枠と、
（ｂ）該型枠内に配筋された鉄筋と、
（ｃ）該型枠と一体化された構造物を形成するように、該型枠内に打たれ固化したコンクリートと
を含み、必要ならば該型枠材料のうちの不要な部分を除去した、建物の基礎、鉄筋コンクリート建物の壁、鉄筋コンクリート塀、鉄筋コンクリート地下室の壁等の、鉄筋コンクリート構造物からなる。
【０００７】
本発明のもう一つは、
イ) 複数個を繋ぎあわせるために端面を互いに相補的な形状とした、コンクリ−ト型枠の対向面を形成するための成形体、
ロ) 該対向面間の間隔を保つ為に使用され、一端に２枚以上のプレ−トを含む端プレ−ト部と、端プレ−ト部を両端としてその間に存在するウェブ部からなる一体のスペ−サ−部材、
を含んでおり、該スペ−サ−部材の端プレ−ト部が該成形体中に鋳込まれているか、又は該スペ−サ−部材の端プレ−ト部の２枚以上のプレ−トを該成形体に挿入する為に、該成形体が、該端プレ−ト部の断面に対応する断面形状の、該端面から中心方向に向かう溝穴を有していることを特徴とするコンクリ−ト用型枠材料からなる。
【０００８】
本発明の更にもう一つは、上記の型枠材料に用いられる、一端に２枚以上のプレ−トを有する端プレ−ト部を含んでいるスペ−サ−部材からなる。
【０００９】
スペ−サ−部材の成形体への取り付け方法
成形体に対するスペ−サ−部材の一端の取り付けは、一つには、図２及び図３の平面図に示すような、成形体の内側平面上に接合端面から内部に向かって設けられている対応断面形状の溝穴５へ、スペ−サ−部材の端プレ−ト部を成形体の該接合端面での繋ぎあわせ前に挿入固定することによってなされる。例えば、端プレ−ト部１が「于」字形の断面のときは、接合端面からみて「于」字形の溝穴（于字の足の部分が成形体の内側表面に溝を形成する）が形成され、そこにスペ−サ−部材の端プレ−ト部が挿入される。図３は、スペ−サ−部材の挿入場所だけ成形体の幅を広くして溝穴を設けることを容易にした例である。コンクリ−トを流し込むときにはコンクリ−ト型枠をなす成形体には非常に大きな圧力がかかるので、これに耐える為に、スペ−サ−部材の端プレ−ト部が、ウェブ部に対し直角の面を有する、成形体溝穴挿入用プレ−トを少なくとも二つ有するのが好ましい。成形体溝穴挿入用プレ−トが一端に２枚以上あると、スペ−サ−部材による成形体の固定効果はずっと優れたものになる。成形体溝穴は、スペ−サ−部材の端プレ−ト部に対応した断面形状を有する。
【００１０】
成形体に対するスペ−サ−部材の一端の取り付けは、別の方法では、図４に示すように、向かい合った成形体のそれぞれにスペ−サ−部材の両端の端プレ−ト部を鋳込んで一体化することによってなされる。
【００１１】
スペ−サ−部材
イ）材質
スペ−サ−部材の材質は、ポリエチレン、ポリプロピレン、ＡＢＳ樹脂、その他のプラスチック、又は金属などの剛性のある材質の材料である。
【００１２】
ロ）スペ−サ−部材の機能
スペ−サ−部材は、型枠の対向面の相対位置を安定的に固定し、コンクリ−ト打ちの再の液圧による対向面を押し広げようとする力をその引張り力で対抗する機能を有するが、その他にも機能を有し得る。スペ−サ−部材と成形体とからなるコンクリ−ト型枠は、コンクリ−トが固まった後にも除去されることなく、鉄筋コンクリ−トと一体の壁構造体を形成する。したがってスペ−サ−部材の端プレ−ト部の最も外側のプレ−トを外側表面に露出するように、スペ−サ−部材の端プレ−ト部挿入用の穴を成形体に設けるか又はスペ−サ−部材を成形体に埋め込めば、スペ−サ−部材の内側表面又は外側表面をなすプレ−トには、内装材又は外装材の取り付け用の雌ネジ穴等を設けたり、内装材又は外装材等を釘、ネジ、接着剤等で取り付けることが可能である。例えば、スペ−サ−部材の成形体中に挿入され又は埋め込まれるプレ−トの更に外側にプレ−トを設け上端でコの字形につなぎ、成形体にはそのつなぎの部分を収容する切り欠きを設けて内側又は外側表面をなすプレ−トとすることが考えられる。また、スペ−サ−部材のウェブ部には、鉄筋を保持しやすいように、突起や凹部を設けることが出来る。また、スペ−サ−部材は、複数本の組立体として販売される鉄筋を収容するためには、ウェブ部が大きなＵ字形をしていてＵ字の空所部分で組立鉄筋を支持すると都合が良い。
【００１３】
成形体
イ）材質
成形体の材質は、発泡ポリスレチン、発泡ポリエチレン、発泡ポリウレタン等が好ましい。大鋸屑等をかためた木質系の成形品を用いることも出来る。また、型枠の片側を上記の様な発泡体の成形体とし、型枠の反対側をコンクリ−ト成形体とすることもできる。例えば、壁の外側がコンクリ−ト、内側を断熱材としたい場合に、そのような型枠が適している場合がある。
【００１４】
ロ）成形体の端部の形状
成形体と成形体の繋ぎ目は、コンクリ−トがもれないものでなければならない。従って、一般には、各成形体は一方の辺の端面に連続した谷状の凹部を、その反対側の辺の端面に連続した峰状の凸部を、相補的な形状で有しており、一般に、繋ぎ目の結合力を増す為に、連続した峰状の凸部は峰上の所々に多角柱形又は円柱形の一段高い凸部を有し、それに対応して連続した谷状の凹部も谷上の所々に多角柱形又は円柱形の一段窪んだ凹部を有するのが好ましい。
【００１５】
【実施例】
以下、図面を参照しながら本発明を説明する。
図１に示されるように、本発明の一具体例のスペ−サ−部材は、端プレ−ト部１，１'、ウェブ部２を有している。端プレ−ト部１，１'は、それぞれ２枚のプレ−ト３、４及び３'、４'を有している。
【００１６】
成形体の端面をつなぐ為の連続する凸部と凹部の形状の例を図５〜７に示す。
【００１７】
【本発明の効果】
１）本発明のスペ−サ−部材は、型枠の対向面の相対位置を安定的に固定する能力が大きい。
２）従って、パネル部材の単位面積あたりのスペ−サ−部材の数を減少することが出来、その分コンクリ−トが少なくなってしまうという欠点が除かれる。
３）造られたコンクリ−ト壁は、コンクリ−ト型枠が完成後断熱材をなし、そしてスペ−サ−部材が内装、外装の取り付け下地や塗装の下地を兼ねたり、下地の固定場所を与えることも出来るので、型枠の取外し作業、断熱材を挿入又は張付る作業、及び内装、外装の為の取り付け下地や塗装用の下地又は下地の固定場所を張付け又は取り付ける作業が不要となって、極めて迅速かつ簡単な建物壁面の完成が可能となる。
４）断熱材のコンクリ−ト壁との一体化によって、高気密、高断熱の高規格な住宅建設が低コストで実現する。

[Industrial application fields]
The present invention relates to a concrete formwork, and a wall structure in which a concrete formwork and a concrete are integrated.
[0002]
[Prior art]
In recent years, in order to raise the standard of the house by increasing the heat insulation and airtightness of the house, and for the purpose of facilitating construction and drastically reducing the cost of housing construction, Synthetic resin molding combined formwork to form fabric foundations and rebar concrete building walls, reinforcing bars placed in the formwork, and squeezed into the formwork The building walls made of concrete are attracting attention and their spread is greatly expected.
[0003]
Such a composite resin mold of a synthetic resin molded body is roughly divided, for example, as described in Japanese Patent Application Laid-Open No. 6-129099, having a concavo-convex structure as a joint end, and from the joint end. In order to fix the interval between the side panel members made of synthetic resin such as polystyrene foam having a T-shaped groove extending toward the center and the side panel members facing each other, it is inserted into the side panel. A spacer member (such a spacer member is a tensile member because it is subjected to a tensile force functionally, but is also referred to as a spacer member in this specification) is assembled into a mold. For example, as described in Japanese Patent Application Laid-Open No. 6-346536, a bridge member that bridges between facing panel members is cast into the panel member to form an integral building component. Things There are things to be formed overlapping seen.
[0004]
[Problems to be solved by the invention]
However, the hydraulic pressure of the concrete is applied to the formwork on which the concrete is struck, and a considerable tensile force is applied to the spacer member. The spacer member used in the above-described prior art formwork material has a poor ability to stably fix the relative position of the formwork. Therefore, the number of spacer members per unit area of the panel member has to be increased, and there is a disadvantage that the amount of concrete decreases accordingly.
[0005]
[Means for solving the problems]
As a result of diligent research to solve the above problems, the present inventor has found that the above problems can be solved by using two or more end plate portions of the spacer member. The present invention has been completed.
[0006]
That is, one of the present invention is
(A) A) A molded body for forming a facing surface of a concrete mold, in which end surfaces are complementary to each other in order to connect a plurality of them,
(B) an integral spacer member that is used to maintain a distance between the opposing surfaces and includes an end plate portion including two or more plates at one end, and a web portion existing between the end plate portions as both ends;
And the end plate portion of the spacer member is cast into the molded body, that is, is integrally molded and embedded in the molded body, or the end plate of the spacer member In order to insert two or more plates of the part into the molded body, the molded body has a slot having a cross-sectional shape corresponding to the cross section of the end plate portion and extending from the end surface toward the center.
A formwork formed of a concrete formwork material characterized by:
(B) a reinforcing bar arranged in the formwork;
(C) including concrete that has been struck and solidified in the mold so as to form a structure integrated with the mold, and if necessary, unnecessary portions of the mold material are removed. It consists of reinforced concrete structures such as building foundations, reinforced concrete building walls, reinforced concrete fences, and reinforced concrete basement walls.
[0007]
Another aspect of the present invention is
A) A molded body for forming the opposing surface of the concrete mold, the end surfaces of which are complementary to each other in order to connect a plurality of them.
B) Used to maintain the distance between the opposing surfaces, and is composed of an end plate portion including two or more plates at one end and a web portion existing between the end plate portions as both ends. Spacer members,
And an end plate portion of the spacer member is cast into the molded body, or two or more plates of the end plate portion of the spacer member are included. In order to insert the molded body into the molded body, the molded body has a slot having a cross-sectional shape corresponding to the cross section of the end plate portion and extending from the end surface toward the center. -It is made of a mold form material.
[0008]
Still another aspect of the present invention is a spacer member including an end plate portion having two or more plates at one end, which is used for the above-mentioned mold material.
[0009]
Method of attaching spacer member to molded body One end of the spacer member to the molded body is attached to the molded body as shown in the plan views of FIGS. The end plate portion of the spacer member is inserted into the slot 5 having a corresponding cross-sectional shape provided inwardly from the joining end surface on the inner plane of the molded body before joining at the joining end surface of the molded body. Made by fixing. For example, when the end plate portion 1 has a “U” -shaped cross section, a “U” -shaped slot (the U-shaped leg portion forms a groove on the inner surface of the molded body) when viewed from the joining end surface. The end plate portion of the spacer member is inserted therein. FIG. 3 shows an example in which it is easy to provide a slot by increasing the width of the molded body only at the insertion position of the spacer member. When the concrete is poured, a very large pressure is applied to the molded body forming the concrete mold. Therefore, in order to withstand this, the end plate portion of the spacer member is perpendicular to the web portion. It is preferable to have at least two molded product slot insertion plates having a surface. If there are two or more plates for inserting the molded product slot at one end, the effect of fixing the molded product by the spacer member becomes much better. The molded body slot has a cross-sectional shape corresponding to the end plate portion of the spacer member.
[0010]
As shown in FIG. 4, the attachment of one end of the spacer member to the molded body is performed by casting end plate portions at both ends of the spacer member in each of the opposed molded bodies. This is done by integrating.
[0011]
Space - Sa - member <br/> b) Material <br/> space - Sa - Material of the member include polyethylene, polypropylene, ABS resin, other plastic, or metal which is a material of a material having rigidity such.
[0012]
B) Function of the spacer member The spacer member stably fixes the relative position of the opposing surface of the mold, and pushes the opposing surface due to the hydraulic pressure of the concrete shot again. It has a function of countering the force to be applied by its tensile force, but may have other functions. The concrete form frame composed of the spacer member and the molded body forms a wall structure integrated with the reinforcing bar concrete without being removed even after the concrete has hardened. Therefore, a hole for inserting the end plate portion of the spacer member is provided in the molded body so that the outermost plate of the end plate portion of the spacer member is exposed to the outer surface, or If the spacer member is embedded in the molded body, the plate forming the inner surface or the outer surface of the spacer member is provided with a female screw hole for attaching the interior material or the exterior material, or the interior material. Or it is possible to attach exterior materials etc. with a nail, a screw, adhesives, etc. For example, a plate is provided on the outer side of a plate inserted or embedded in the molded body of the spacer member and is connected to a U-shape at the upper end, and the molded body is a notch that accommodates the joint portion. It is conceivable to provide a plate that forms the inner or outer surface by providing a plate. In addition, the web portion of the spacer member can be provided with a protrusion or a recess so as to easily hold the reinforcing bar. In addition, in order to accommodate the reinforcing bars sold as a plurality of assemblies, the spacer member is convenient if the web portion has a large U shape and the assembled reinforcing bars are supported by U-shaped voids. good.
[0013]
Molded body a) Material The material of the molded body is preferably foamed polystyrene, foamed polyethylene, foamed polyurethane or the like. It is also possible to use a wood-based molded product made of large sawdust or the like. Also, one side of the mold can be a foamed molded body as described above, and the other side of the mold can be a concrete molded body. For example, such a form may be suitable when the outside of the wall is concrete and the inside is a heat insulating material.
[0014]
B) Shape of the end of the molded body The joint between the molded body and the molded body must be free of concrete. Accordingly, in general, each molded body has a valley-like concave portion continuous to the end face of one side, and a ridge-like convex portion continuous to the end face of the opposite side in a complementary shape, In general, in order to increase the joint strength of the joint, the continuous peak-shaped convex part has a polygonal columnar or cylindrical one-step higher convex part at the top of the peak, and the corresponding valley-shaped concave part is correspondingly continuous. Also, it is preferable to have concave portions that are recessed in one step in a polygonal column shape or a cylindrical shape in places on the valley.
[0015]
【Example】
The present invention will be described below with reference to the drawings.
As shown in FIG. 1, the spacer member of one embodiment of the present invention has end plate portions 1, 1 ′ and a web portion 2. The end plate portions 1 and 1 'have two plates 3, 4 and 3' and 4 ', respectively.
[0016]
The example of the shape of the continuous convex part and concave part for connecting the end surface of a molded object is shown to FIGS.
[0017]
[Effect of the present invention]
1) The spacer member of the present invention has a large ability to stably fix the relative position of the opposed surfaces of the mold.
2) Therefore, the number of spacer members per unit area of the panel member can be reduced, and the disadvantage that the amount of concrete decreases correspondingly is eliminated.
3) The concrete wall thus constructed is used as a heat insulating material after completion of the concrete formwork, and the spacer member also serves as an interior / exterior mounting base or paint base, or a place for fixing the base. Since it can be given, the work of removing the formwork, the work of inserting or attaching the heat insulating material, and the work of attaching or attaching the installation base for interior and exterior, the base for painting, or the fixing place of the base become unnecessary. As a result, the building wall can be completed very quickly and easily.
4) Highly airtight and highly insulated high-standard housing construction is realized at low cost by integrating the insulation with the concrete wall.
