Description

【０００１】
【発明の属する技術分野】
本発明は、コンクリート壁を形成する為の型枠の保持に使用される型枠保持具に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
一般にコンクリート壁30を形成する場合には、図１に図示したように、所定間隔を置いて型枠31を立設し、この型枠31間にセパレータ32を架設し、このセパレータ32の両端にボルト部33を突設したコーン34を螺着して該ボルト部33を型枠31から嵌挿突出せしめ、このボルト部33の突出部に、継ぎボルト杆35を螺着し、この継ぎボルト杆35に押え部材36を被嵌し、この押え部材36と前記型枠31との間に単管40・41を配設し、前記継ぎボルト杆35にナット37を螺着せしめることで前記押え部材36により前記単管40・41を型枠31に押し付けて該型枠31を支承し、前記型枠31間にコンクリートを注入硬化せしめてコンクリート壁30を形成している。
【０００３】
尚、業界では、継ぎボルト杆35，押え部材36及びナット37を、まとめてフォームタイ（登録商標、符号39）と呼んでいる。
【０００４】
ところで、この型枠31に押し付けられる単管40・41は、丸パイプ若しくは角パイプが採用されている。しかし、丸パイプは強度が小さいという欠点があり、一本で使用するのに適さず（二本づつ使用しなければならない）、よって、一本で使用する場合には角パイプが採用されている。
【０００５】
図２は、この角パイプを用いた型枠31の保持構成であり、所定間隔を置いて配設される複数の縦パイプ40と、この縦パイプ40に交叉状態にして所定間隔を置いて配設される複数の横パイプ41とが設けられており、また、この横パイプ41は所定長である為、複数本の横パイプ41を連設する構成されている。具体的には、一の横パイプ41の左右端部は隣接する横パイプ41の端部と上下方向に並設されており、前記フォームタイ39は、この並設部を押さえるタイプ、即ち、上下二本の横パイプ41を押さえるタイプ（符号42）と、前記並設部以外を押さえるタイプ、即ち、一本の横パイプ41を押さえるタイプ（符号43）の二種類が使用されている（以下、従来例という。）。
【０００６】
従って、従来は、フォームタイ42では横パイプ一本を押さえる構造となっておらず、また、フォームタイ43では横パイプ二本を押さえる構造となっていない為、この従来例に係る二種類のフォームタイ42・43を必ず用意しなければならず、厄介であるという問題点がある。
【０００７】
本発明は、上記問題点を解決することができる型枠保持具を提供するものである。
【０００８】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【０００９】
コンクリート壁１を形成する為の型枠２の保持に使用される型枠保持具であって、前記型枠２から突出する架設部材11に連結される継合体３と、この継合体３に被嵌される押え部材６と、この押え部材６を前記型枠２側へ押圧する押圧体７とから成り、前記継合体３としてボルトが採用されるとともに、前記押圧体７としてナット体が採用されており、前記押え部材６には前記型枠２に当接する支持脚８が設けられ、また、前記押え部材６には前記ボルトが遊嵌状態で挿入される上下方向に長い長孔状の遊嵌孔10が設けられ、また、前記押え部材６の前記型枠２側の面には前記継合体３を前記遊嵌孔10に挿入した際、この継合体３を境にした上下位置に配される二本の角部材４ａ・４ｂを支持する支持部５が設けられ、また、前記押え部材６には該押え部材６の変形を防止するリブ20が突設され、このリブ20は前記支持部５から支持脚８に至る位置まで延設され、また、前記遊嵌孔10は前記リブ20に設けられており、このリブ20にして前記遊嵌孔10の周囲は前記ナット体の締め付けを阻害しない平面形状に構成されていることを特徴とする型枠保持具に係るものである。
【００１０】
また、コンクリート壁１を形成する為の型枠２の保持に使用される型枠保持具であって、前記コンクリート壁１に埋設され前記型枠２から突出する架設部材11に連結される継合体３と、この継合体３に被嵌される押え部材６と、この押え部材６を前記型枠２側へ押圧する押圧体７とから成り、前記継合体３としてボルトが採用されるとともに、前記押圧体７としてナット体が採用されており、前記押え部材６には前記型枠２に当接する支持脚８が設けられ、また、前記押え部材６には前記ボルトが遊嵌状態で挿入される上下方向に長い長孔状の遊嵌孔10が設けられ、また、前記押え部材６の前記型枠２側の面には前記継合体３を前記遊嵌孔10に挿入した際、この継合体３を境にした上下位置に配される二本の角部材４ａ・４ｂを支持する支持部５が設けられ、また、前記押え部材６には該押え部材６の変形を防止するリブ20が突設され、このリブ20は前記支持部５から支持脚８に至る位置まで延設され、また、前記遊嵌孔10は前記リブ20に設けられており、このリブ20にして前記遊嵌孔10の周囲は前記ナット体の締め付けを阻害しない平面形状に構成されていることを特徴とする型枠保持具に係るものである。
【００１１】
また、請求項１，２いずれか１項に記載の型枠保持具において、前記支持脚８の内部と前記支持部５のなす角は、鈍角に設定されていることを特徴とする型枠保持具に係るものである。
【００１２】
また、請求項１〜３いずれか１項に記載の型枠保持具において、前記支持脚８には前記型枠２と面当接する面当接部９が設けられていることを特徴とする型枠保持具に係るものである。
【００１３】

【００１４】
【発明の作用及び効果】
押え部材６の型枠２側の面にして継合体３の上下位置には二本の角部材４ａ・４ｂを支持する支持部５が設けられているから、この押え部材６で二本の角部材４ａ・４ｂを良好に押さえることができる。
【００１５】
また、押え部材６には型枠２に当接する支持脚８が設けられているから、押え部材６で角部材４ａを一本だけ押さえる場合でも、該押え部材６は前記角部材４ａと支持脚８の双方により二点支持されて安定状態となる為、該押え部材６で一本だけの角部材４ａでも良好に押さえることができる。
【００１６】
従って、角部材４ａが一本だけの場所でも、角部材４ａ・４ｂが二本の場所でも、同じ型枠保持具により該角部材４を良好に支持することができる。
【００１７】
また、取り付け箇所による型枠保持具の選択が不要となり、作業時間の短縮が達成されることになる。
【００１８】
【発明の実施の形態】
図３〜６は本発明の一実施例を図示したものであり、以下に説明する。
【００１９】
本実施例は、コンクリート壁１を形成する為の型枠２の保持に使用される型枠保持具であって、前記コンクリート壁１に埋設され前記型枠２から突出する架設部材11に連結される継合体３と、この継合体３に被嵌される押え部材６と、該押え部材６を型枠２側へ押圧する押圧体７とから成り、押え部材６の型枠２側の面にして前記継合体３の上下位置には二本の角部材４ａ・４ｂを支持する支持部５が設けられ、この押え部材６には前記型枠２に当接する支持脚８が設けられている。
【００２０】
型枠２は、平板に所定間隔を置いて複数の縦条16（例えば、角パイプ）を設けたもので、この型枠２は所定間隔を置いて左右に立設するものである（尚、図４，５は片側の型枠２のみを図示している。）。また、一枚の型枠２は、複数枚の型枠を左右に並設して一体化した構成を採用している。
【００２１】
型枠２の外面には、前記縦条16に交叉状態にして所定間隔を置いて配設される複数の横角パイプ、即ち、前記角部材４が設けられ、この角部材４によって前記複数枚の型枠が一体化せしめられている。また、この角部材４ａ・４ｂは所定長である為、複数本の角部材４ａ・４ｂを連設する構成とされている。具体的には、一の角部材４ａの左右端部は隣接する角部材４ｂの端部と上下方向に並設されている。
【００２２】
型枠２間には、前記コンクリート壁１に埋設され前記型枠２から突出する前記架設部材11が架設されている。
【００２３】
この架設部材11は、前記コンクリート壁１に埋設される埋設ボルト12（セパレータと呼ばれる）に前記型枠２から嵌挿して突出するボルト部13付コーン14を連結した架設部材11が採用されている。尚、この埋設ボルト12とボルト部13付コーン14とは螺着脱自在に構成されている。
【００２４】
継合体３は、ボルト杆が採用されている。また、継合体３の底部には、前記型枠２から突出するボルト部13と螺着する螺着部15が設けられている。尚、前記角部材４ａ・４ｂは、この継合体３の上側若しくは下側（二本の角部材４ａ・４ｂが上下並設されている部位では、上下両方。）に配設されている。
【００２５】
押圧体７は、この継合体３に螺着するナット体が採用されている。
【００２６】
押え部材６には、前記継合体３が遊嵌状態で嵌挿される長孔状の遊嵌孔10が設けられている。従って、この押え部材６は、継合体３に被嵌した状態で、該遊嵌孔10の長さ分、微動することができる。
【００２７】
また、この遊嵌孔10は、上下方向に長い長孔状に形成されている。従って、押え部材６は、上下方向、即ち、二本の角部材４ａ・４ｂの並設方向に微動することができる。
【００２８】
支持部５は、この継合体３の上側及び下側の双方に配設された二本の角部材４ａ・４ｂを支持したり、或いは、継合体３の上側若しくは下側に配設された一本の角部材４を支持したりできるように構成されている。具体的には、押え部材６の型枠２側の面には、二本の角部材４ａ・４ｂの夫々一側面と面当接する当接部17が設けられ、この当接部17の上部には、上側の角部材４ａの上角縁に被嵌する上被嵌部18が設けられ、また、当接部17の下部には、下側の角部材４ｂの下角縁に被嵌する下被嵌部19が設けられた構成が採用されている。従って、この支持部５で二本の角部材４ａ・４ｂを支持する場合には、二本の角部材４ａ・４ｂの夫々一面（表面側の面）に前記当接部17が当接し、また、この角部材４ａ・４ｂの上下角縁に夫々上被嵌部18及び下被嵌部19が被嵌した安定状態で該二本の角部材４ａ・４ｂを支持することができる。また、この支持部５で、一本の角部材４を支持する場合には、一本の角部材４の一面（表面側の面）に前記当接部17が当接し、また、この一本の角部材４の上角縁に上被嵌部18が被嵌し、更に、この一本の角部材４の下面が継合体３に当接若しくは近接した安定状態で該一本の角部材４を支持することができる。
【００２９】
尚、一本の角部材４の下角縁に下被嵌部19が被嵌し、更に、この一本の角部材４の上面が継合体３に当接若しくは近接する場合でも同様である。
【００３０】
また、本実施例の押え部材６は、前記支持脚８が上被嵌部18若しくは下被嵌部19を兼用した構成を採用している。
【００３１】
この支持脚８は、支持部５で角部材４を支持した際、型枠２に当接して押え部材６を安定させ、該押え部材６での角部材４の支持をより一層確実にするものである。特に、角部材４を一本だけ支持する場合でも、支持脚８が存在すると、押え部材６が前記一本の角部材４と型枠２との双方に当接することになり、該一本だけの角部材４の支持を安定性良く行うことができる。
【００３２】
尚、一本だけの角部材４の支持を行う場合、該角部材４と支持脚８とが継合体３を介して対向状態となるようにすると該角部材４と支持脚８とが離れ、必然的に押え部材６が安定する。
【００３３】
また、支持脚８には型枠２と面当接する面当接部９が設けられている。従って、この支持脚８が型枠２に食い込んだりすることは防止され、前記押え部材６は安定性良く角部材４を支持することができる。尚、型枠２は支持脚８が食い込み易い木材が使用される場合が非常に多い。
【００３４】
また、支持脚８の内部（内面）と支持部５の当接部17とのなす角は、鈍角に設定されている。
【００３５】
また、押え部材６は一枚の細長板材を折曲して前記支持部５と前記支持脚８を夫々形成する方法により製造されている。
【００３６】
また、押え部材６には、該押え部材６の変形を可及的に防止する為のリブ20が設けられている。また、このリブ20は、押え部材６の支持部５から支持脚８に至る位置まで延設されている。また、このリブ20は、前記押圧体７で押え部材６を押圧せしめた際、この押圧の邪魔にならない形状に設定されている。具体的には、本実施例ではリブ20の上面を平面に設定している。この点、例えば、遊嵌孔10の周囲が突出していると、該突出によって押圧体７の押圧が阻害され、また、遊嵌孔10の周囲が陥没していると、この陥没に押圧体７が嵌まり込んでしまい、ナット体であると回動不能になる等の問題が発生する。
【００３７】
本実施例は上述のように構成したから、角部材４が一本だけ設けられている位置でも、角部材４が二本設けられている位置でも、同じ型枠保持具によって該角部材４を支持して型枠２を保持できる実用性に秀れた型枠保持具となる。
【００３８】
即ち、所定長の角部材４ａ・４ｂを隣接する角部材４ａ・４ｂの端部を並設せしめて該角部材４ａ・４ｂを配設する場合、従来であれば、この並設部で二本の角部材４ａ・４ｂを保持する型枠保持具と、この並設部以外の部位で一本の角部材４を保持する型枠保持具との二種類を用意しなければならないという問題点があったが、本実施例によれば、一種類の型枠保持具のみ用意しておけば良いことになり、使用する型枠保持具の間違い等も発生せず、極めて良好に型枠形成作業を行うことができる。
【００３９】
また、本実施例は、型枠２を強固に保持できる角部材４で支持するものであるから、該角部材４を必ず二本並設させる必要がなく、一本の角部材４のみでの型枠２の保持も可能となる。従って、二本分の作業（運搬や設置）を一本分の作業とすることができ、実験によれば、作業時間を１０％以上短縮できることも確認された。更に、例えば、型枠２を傾斜状態で設置する場合、丸パイプを採用すると該丸パイプの転動によって型枠２が位置ずれする問題も解消できる。
【００４０】
また、支持脚８には型枠２と面当接する面当接部９が設けられているから、この支持脚８が型枠２にめり込んだりせず、よって、押え部材６は安定状態で角部材４を支持できることになる。
【００４１】
また、支持脚８の内部と支持部５（当接部17）のなす角は鈍角に設定されているから、支持部５で角部材４を支持する際に該角部材４と支持脚８との間に隙間が出来易く、よって、角部材４や押え部材６の配設作業を良好に行うことができる。
【００４２】
また、継合体３としてボルト杆が採用され、押圧体７としてナット体が採用されているから、例えば、クサビによって押え部材６を押圧するものと異なり、押圧体７の押圧が弛みにくく、必然的に押え部材６は安定性良く且つ強固に角部材４を支持できることになる。更に、電動締付工具等の使用により、前記ナット体の締め付けを簡単且つ迅速に行って型枠２の形成を効率良く行うことができる。
【００４３】
また、押え部材６に設けられ継合体３が挿入される孔は、該継合体３が遊嵌状態で嵌挿される長孔状の遊嵌孔10に設定されているから、型枠２（実際は架設部材11）に付設された継合体３に対して押え部材６が微動できることになり、この微動により押え部材６の位置を調整して前記角部材４を配設し易くしたり、更に、この角部材４を適正に支持したりできることになる。
【００４４】
また、この遊嵌孔10は二本の角部材４ａ・４ｂの並設方向に長いから、前記押え部材６の微動可能方向も該二本の角部材４ａ・４ｂの並設方向となり、よって、例えば、支持脚８と継合体３との距離を調整して前記角部材４ａ・４ｂを配設し易くしたり、この角部材４ａ・４ｂを適正に支持したりできることになる。

BACKGROUND OF THE INVENTION
The present invention relates to a mold holder used to hold a mold for forming a concrete wall.
[0002]
[Prior art and problems to be solved by the invention]
In general, when the concrete wall 30 is formed, as shown in FIG. 1, a mold frame 31 is erected at a predetermined interval, and separators 32 are installed between the mold frames 31. A cone 34 projecting from a bolt part 33 is screwed and the bolt part 33 is fitted and protruded from the mold 31, and a joint bolt 杆 35 is screwed to the projecting part of the bolt part 33, and the joint bolt 杆A presser member 36 is fitted on 35, single tubes 40 and 41 are disposed between the presser member 36 and the mold frame 31, and a nut 37 is screwed onto the joint bolt rod 35 to thereby press the presser member. The single pipes 40 and 41 are pressed against the mold 31 by 36 to support the mold 31, and concrete is injected and cured between the molds 31 to form the concrete wall 30.
[0003]
In the industry, the joint bolt rod 35, the pressing member 36 and the nut 37 are collectively referred to as a foam tie (registered trademark, symbol 39).
[0004]
By the way, the single pipes 40 and 41 pressed against the mold 31 are round pipes or square pipes. However, round pipes have the disadvantage of low strength and are not suitable for single use (must be used in pairs), so square pipes are used for single use. .
[0005]
FIG. 2 shows a structure for holding the formwork 31 using this square pipe, and a plurality of vertical pipes 40 arranged at predetermined intervals, and arranged at predetermined intervals in a crossed state with the vertical pipes 40. A plurality of horizontal pipes 41 are provided. Since the horizontal pipe 41 has a predetermined length, a plurality of horizontal pipes 41 are connected in series. Specifically, the left and right end portions of one horizontal pipe 41 are juxtaposed in the vertical direction with the end portions of the adjacent horizontal pipe 41, and the foam tie 39 is a type that presses this juxtaposed portion, that is, the upper and lower ends. Two types are used: a type that presses two horizontal pipes 41 (reference numeral 42) and a type that presses other than the side-by-side portion, that is, a type that presses one horizontal pipe 41 (reference numeral 43) (hereinafter, It is called a conventional example.)
[0006]
Therefore, conventionally, the foam tie 42 does not have a structure for holding one horizontal pipe, and the foam tie 43 does not have a structure for holding two horizontal pipes. Thailand 42 and 43 must be prepared, which is problematic.
[0007]
The present invention provides a mold holder that can solve the above problems.

The holding member 6 is provided with a long hole-like loose fitting hole 10 into which the joint body 3 is inserted in a loosely fitted state. Therefore, the pressing member 6 can be slightly moved by the length of the loose fitting hole 10 in a state of being fitted to the joint body 3.
[0027]
The loose fitting hole 10 is formed in a long hole shape that is long in the vertical direction. Therefore, the pressing member 6 can be finely moved in the vertical direction, that is, in the direction in which the two corner members 4a and 4b are arranged side by side.
[0028]
The support portion 5 supports the two corner members 4a and 4b disposed on both the upper side and the lower side of the joint body 3, or is disposed on the upper side or the lower side of the joint body 3. The corner member 4 of the book can be supported. Specifically, on the surface of the presser member 6 on the side of the mold 2, a contact portion 17 that is in surface contact with one side surface of each of the two square members 4 a and 4 b is provided. Is provided with an upper fitting portion 18 that fits on the upper corner edge of the upper corner member 4a, and a lower sheath that fits on the lower corner edge of the lower corner member 4b at the lower portion of the contact portion 17. A configuration in which the fitting portion 19 is provided is employed. Therefore, when the two corner members 4a and 4b are supported by the support portion 5, the abutment portion 17 abuts on one surface (surface on the surface side) of each of the two corner members 4a and 4b. The two corner members 4a and 4b can be supported in a stable state in which the upper fitting portion 18 and the lower fitting portion 19 are fitted to the upper and lower corner edges of the corner members 4a and 4b, respectively. Further, when the support member 5 supports a single square member 4, the contact portion 17 comes into contact with one surface (surface on the front side) of the single square member 4. An upper fitting portion 18 is fitted to the upper corner edge of the corner member 4, and the one corner member 4 is in a stable state in which the lower surface of the one corner member 4 is in contact with or close to the joint 3. Can be supported.
[0029]
The same applies to the case where the lower fitting portion 19 is fitted to the lower corner edge of one corner member 4 and the upper surface of the one corner member 4 is in contact with or close to the joint 3.
[0030]
Further, the presser member 6 of this embodiment employs a configuration in which the support leg 8 also serves as the upper fitting portion 18 or the lower fitting portion 19.
[0031]
When the corner member 4 is supported by the support portion 5, the support leg 8 abuts against the mold frame 2 to stabilize the presser member 6, thereby further reliably supporting the corner member 4 with the presser member 6. It is. In particular, even when only one corner member 4 is supported, if the support leg 8 is present, the presser member 6 comes into contact with both the one corner member 4 and the mold 2, and only this one is supported. The corner member 4 can be supported with good stability.
[0032]
When only one corner member 4 is supported, the corner member 4 and the support leg 8 are separated from each other when the corner member 4 and the support leg 8 are opposed to each other via the joint body 3. Inevitably, the pressing member 6 is stabilized.
[0033]
Further, the support leg 8 is provided with a surface contact portion 9 that is in surface contact with the mold 2. Therefore, the support legs 8 are prevented from biting into the mold 2 and the pressing member 6 can support the corner member 4 with high stability. In many cases, the mold 2 is made of wood that the support legs 8 can easily bite into.
[0034]
The angle formed between the inside (inner surface) of the support leg 8 and the contact portion 17 of the support portion 5 is set to an obtuse angle.
[0035]
The pressing member 6 is manufactured by a method in which a single elongated plate material is bent to form the support portion 5 and the support leg 8 respectively.
[0036]
Further, the presser member 6 is provided with a rib 20 for preventing the presser member 6 from being deformed as much as possible. The rib 20 extends to a position from the support portion 5 of the presser member 6 to the support leg 8. The rib 20 is set to a shape that does not interfere with the pressing when the pressing member 6 is pressed by the pressing body 7. Specifically, in this embodiment, the upper surface of the rib 20 is set to a plane. In this regard, for example, when the periphery of the loose fitting hole 10 protrudes, the protrusion of the pressing member 7 is inhibited by the protrusion, and when the periphery of the loose fitting hole 10 is depressed, the pressing member 7 is depressed. Will be fitted, and if it is a nut body, the problem that it will become impossible to rotate will generate | occur | produce.
[0037]
Since the present embodiment is configured as described above, the corner member 4 is moved by the same mold holder at the position where only one corner member 4 is provided or at the position where two corner members 4 are provided. It becomes a formwork holder excellent in practicality that can support and hold the formwork 2.
[0038]
That is, when the corner members 4a and 4b are arranged by arranging the end portions of the adjacent corner members 4a and 4b side by side with the corner members 4a and 4b of a predetermined length, conventionally, two pieces are provided at the side by side. There is a problem that two types of mold holders for holding the corner members 4a and 4b and a mold holder for holding one corner member 4 at a portion other than the juxtaposed portion must be prepared. However, according to the present embodiment, it is only necessary to prepare one type of formwork holder, and there is no mistake in the formwork holder to be used. It can be performed.
[0039]
Further, in this embodiment, since the formwork 2 is supported by the corner member 4 that can hold the mold 2 firmly, it is not always necessary to arrange the two corner members 4 side by side, and only one corner member 4 is used. The mold 2 can be held. Therefore, two operations (transportation and installation) can be made into one operation, and according to experiments, it was confirmed that the operation time can be reduced by 10% or more. Furthermore, for example, when the mold 2 is installed in an inclined state, the use of a round pipe can also solve the problem that the mold 2 is displaced due to rolling of the round pipe.
[0040]
Further, since the support leg 8 is provided with the surface abutting portion 9 that comes into surface contact with the mold 2, the support leg 8 does not sink into the mold 2, and therefore the presser member 6 is in a stable state with a corner. The member 4 can be supported.
[0041]
Further, since the angle formed between the inside of the support leg 8 and the support part 5 (contact part 17) is set to an obtuse angle, when the corner member 4 is supported by the support part 5, the corner member 4 and the support leg 8 Therefore, the gap member 4 and the presser member 6 can be disposed satisfactorily.
[0042]
In addition, since a bolt rod is employed as the joint body 3 and a nut body is employed as the pressing body 7, for example, unlike the case where the pressing member 6 is pressed by wedges, the pressing of the pressing body 7 is difficult to loosen and is inevitably necessary. In addition, the pressing member 6 can support the corner member 4 with good stability and strength. Furthermore, by using an electric clamping tool or the like, the nut body can be easily and quickly tightened to form the mold 2 efficiently.
[0043]
Further, since the hole provided in the holding member 6 and into which the joined body 3 is inserted is set as a long hole-like loose fitting hole 10 into which the joined body 3 is inserted in a loosely fitted state, the mold frame 2 (actually The presser member 6 can be finely moved with respect to the joint body 3 attached to the erection member 11), and the position of the presser member 6 can be adjusted by this fine movement so that the corner member 4 can be easily disposed. The corner member 4 can be properly supported.
[0044]
Further, since the loose fitting hole 10 is long in the direction in which the two corner members 4a and 4b are arranged in parallel, the direction in which the pressing member 6 can be finely moved is also the direction in which the two corner members 4a and 4b are arranged in parallel. For example, the distance between the support leg 8 and the joint 3 can be adjusted so that the corner members 4a and 4b can be easily disposed, and the corner members 4a and 4b can be appropriately supported.
