Description

本発明は、住宅のコンクリート基礎形成時における、平行状態の左右の基礎型枠板の間隔を保持する基礎型枠間隔保持用金物および基礎にアンカーボルトを取り付ける際に、打設されたコンクリートが硬化するまで、アンカーボルトを保持するアンカーボルト支持用金物に関する。   In the present invention, when a concrete foundation of a house is formed, when the anchor bolts are attached to the foundation mold frame interval holding hardware and the foundation to hold the gap between the left and right foundation mold plates in a parallel state, the placed concrete is hardened. The present invention relates to an anchor bolt supporting hardware that holds the anchor bolt until it is done.

従来のコンクリート構造物の基礎型枠において、左右の基礎型枠板の間隔を保持する金物としては、図５に示すように、平行状態の左右の型枠板４Ａ、４Ｂから構成されている型枠４において、幅止金物本体２と鉄ピン３から構成され、左右の型枠板４Ａ、４Ｂの長手方向と直交方向をもって掛架した幅止金物本体２で左右の型枠板の内面を支持し、幅止金物本体の外方部分に打込む鉄ピン３で左右の型枠板の外面を支持するよう構成されているものが知られている（例えば、特許文献１参照。以下「従来技術１」という。）。   As shown in FIG. 5, in a conventional concrete structure foundation formwork, a metal mold that is formed of left and right formwork boards 4A and 4B in a parallel state as shown in FIG. In the frame 4, the inner surface of the left and right mold plates is supported by the width bracket main body 2 which is composed of the width bracket main body 2 and the iron pin 3 and is suspended in a direction orthogonal to the longitudinal direction of the left and right mold plate plates 4A and 4B. And what is comprised so that the outer surface of a left and right formwork board may be supported with the iron pin 3 driven in the outer part of a width | variety metal fitting main body (for example, refer patent document 1. Hereinafter, "the prior art." 1 ”).

また、一般に、住宅のコンクリート基礎には、基礎と上部構造物となる住宅の躯体とを接合するためのアンカーボルトが、下部をコンクリート基礎に埋設し、上部をコンクリート基礎上面から上方に延出した状態で取り付けられている。上記アンカーボルトの基礎への取り付けは、例えば、コンクリート基礎用の型枠にコンクリートを打設する前に、アンカーボルトをその下部が打設されたコンクリートに埋設されるように所定位置に配置し、次いで、型枠内にコンクリート打設することで行われている。   Moreover, in general, anchor bolts for joining the foundation and the housing structure of the upper structure are embedded in the concrete foundation of the house, and the lower part is buried in the concrete foundation and the upper part extends upward from the upper surface of the concrete foundation. It is attached in a state. Installation of the anchor bolt to the foundation, for example, before placing the concrete in the concrete foundation mold, place the anchor bolt in a predetermined position so that the lower part of the anchor bolt is buried in the concrete, Next, concrete is placed in the mold.

従来、コンクリート打設前にアンカーボルトを所定位置に配置するためのアンカーボルト支持具として、図６に示されるように、基礎型枠２の互いに対向して配置される二つの型枠材３、３上に架け渡された状態で載置される矩形状の支持板４と、支持板４の両端部において、支持板４の一部を切り抜いて下方に折り曲げた規制部５、５と、上記支持板４の中央部において略垂直に立設された支柱板部６と、該支柱板部６の上端部から支持板４と平行に延出した延出板部７と、上記支持板４及び延出板部７の互いに重なる位置にそれぞれ設けられた挿通孔８、９と、アンカーボルト１０の上端部に螺合させられるナット１１とからなるものが知られている（例えば、特許文献２参照。以下「従来技術２」という。）。
特開２００３−５６１８０号公報 特開平１０−２３７８７６号公報 Conventionally, as an anchor bolt support for placing anchor bolts at a predetermined position before placing concrete, as shown in FIG. 6, two formwork members 3 arranged opposite to each other of the base formwork 2, A rectangular support plate 4 placed in a state of being bridged on the base plate 3, and at both ends of the support plate 4, the restriction portions 5 and 5 cut out from the support plate 4 and bent downward; A support plate portion 6 erected substantially vertically at the center of the support plate 4, an extension plate portion 7 extending in parallel with the support plate 4 from the upper end portion of the support plate portion 6, the support plate 4, and the support plate 4 There is known one that includes insertion holes 8 and 9 provided at positions where the extension plate portion 7 overlaps each other, and a nut 11 that is screwed into an upper end portion of the anchor bolt 10 (see, for example, Patent Document 2). (Hereinafter referred to as “Prior Art 2”).
JP 2003-56180 A Japanese Patent Laid-Open No. 10-237876

しかし、従来技術１の基礎型枠板の間隔を保持する金物は、平行状態の左右の型枠板の間隔をある程度一定に保持するものであるが、アンカーボルトを保持することはできなかった。また、左右の型枠板４Ａ、４Ｂを保持する際、型枠板の内側は幅止金物本体２に当接するため、一応、内側の位置は決められるが、型枠板の外側は鉄ピン３で止められるため、打ち込まれる鉄ピン３の打ち込み状態により外側に動いたり、あるいは、反対側の型枠を押す方向に動いたりするという欠点があった。   However, the hardware that holds the interval between the basic mold plates of the prior art 1 holds the interval between the left and right mold plates in the parallel state to a certain degree, but cannot hold the anchor bolt. Further, when the left and right mold plates 4A and 4B are held, the inner side of the mold plate abuts against the width stopper main body 2, so that the inner position is determined, but the outer side of the mold plate is the iron pin 3 Therefore, there is a drawback that the iron pin 3 is moved outward depending on the driven state of the iron pin 3 or moved in the direction of pressing the opposite formwork.

一方、従来技術２のアンカーボルト支持具は、アンカーボルトを支持する機能を有するだけで、基礎型枠板の間隔を保持する機能を有するものではなかった。
すなわち、従来技術２においては、支持板４の一部を切り抜いて下方に折り曲げた規制部５、５が設けられているが、これは支持板４を型枠の中央に位置させるものであって、左右の型枠板の間隔を保持するためのものではなかった。 On the other hand, the anchor bolt support of prior art 2 only has a function of supporting the anchor bolt, and does not have a function of maintaining the interval between the foundation mold plates.
That is, in the prior art 2, there are provided restricting portions 5 and 5 which are cut out and bent downwards on a part of the support plate 4, which is to position the support plate 4 at the center of the mold. It was not for maintaining the distance between the left and right mold plates.

このように、従来技術においては、基礎型枠板の間隔を保持する金物とアンカーボルトを支持する金物は別々に形成され、別々に設置されおよび撤去されることから、金物の種類が増えると同時に金物の設置および撤去作業が増大するという問題があった。また、これら金物は基礎型枠の長手方向に所定の間隔で複数設置されるものであり、２種類の金物が設置されるとそれらの設置のピッチが細かくなり、コンクリート打設時に打設されるコンクリートが金物に邪魔される格好になり、スムースなコンクリートの流れが阻害されるという問題もあった。   In this way, in the prior art, the hardware that holds the gap between the base mold plates and the hardware that supports the anchor bolt are formed separately, and are separately installed and removed. There was a problem that the installation and removal work of hardware increased. In addition, a plurality of these hardwares are installed at predetermined intervals in the longitudinal direction of the foundation mold, and when two types of hardware are installed, the pitch of the installation becomes fine and is placed when placing concrete. There was also a problem that the concrete was disturbed by hardware, and the flow of the concrete was hindered.

本発明は、上記した従来技術の有する問題点を解決するためになされたもので、１つの金物に基礎型枠板の間隔を保持する機能とアンカーボルトを支持する機能とを併せ備えさせることにより、金物の種類を減少させるとともに部材の合理化を図ることができ、さらに、金物の設置および撤去作業を大幅に低減させることのできる基礎型枠間隔保持用およびアンカーボルト保持用金物を提供することを目的とするものである。   The present invention has been made to solve the above-described problems of the prior art, and by providing a single hardware with a function of maintaining the distance between the base mold plates and a function of supporting anchor bolts. To provide hardware for holding the base formwork and holding anchor bolts that can reduce the types of hardware and rationalize the members, and can greatly reduce the installation and removal of hardware. It is the purpose.

また、本発明の基礎型枠間隔保持用およびアンカーボルト保持用金物は、アンカーボルト保持板が、ベース板から垂直に立ち上がる両側板と該両側板間に延びベース板に平行な天板とからなることを特徴としている。 In order to achieve the above-mentioned object, the metal mold for holding the basic formwork spacing and anchor bolts according to the present invention is a metal mold for holding the space between the left and right basic formwork boards in parallel and holding the anchor bolts. A base plate laid over and placed on the base plate; a pair of spacing members fixed to the lower side of the base plate and fitted to the upper ends of the left and right foundation mold plates; and the base An anchor bolt holding plate standing on the upper side of the plate and having a predetermined interval and a parallel portion is provided, and an anchor bolt insertion hole is provided in the base plate and the anchor bolt holding plate.

図１は、本実施の形態に係る基礎型枠間隔保持用およびアンカーボルト保持用金物が設置された状態を示す要部の斜視図であり、コンクリートの打設前の状態を示している。
コンクリートが打設される個所には、基礎砕石４１が敷き詰められ、その上に、左右の基礎型枠板４０、４０が平行状態に設置されるものである。基礎型枠板４０、４０は所定の間隔で長手方向に延びており、所定の高さを有している。
基礎型枠板４０、４０の間隔を一定に保持するとともに、アンカーボルトを保持する基礎型枠間隔保持用およびアンカーボルト保持用金物２０が基礎型枠板４０、４０の上部に長手方向に所定の間隔で複数個載置され、基礎型枠板４０、４０が所定の長さにわたって平行かつ一定幅で設置される。 FIG. 1 is a perspective view of a main part showing a state in which the base formwork interval holding metal fittings and anchor bolt holding metal fittings according to the present embodiment are installed, and shows a state before placing concrete.
The ground crushed stone 41 is spread over the place where the concrete is placed, and the left and right foundation mold plates 40, 40 are installed in a parallel state thereon. The base mold plates 40, 40 extend in the longitudinal direction at a predetermined interval and have a predetermined height.
While keeping the interval between the base mold plates 40, 40 constant, the base mold frame holding metal fixture 20 for holding the anchor bolts and the anchor bolt holding hardware 20 are arranged in the longitudinal direction above the basic mold plates 40, 40 in the longitudinal direction. A plurality of the base mold plates 40, 40 are placed in parallel and at a constant width over a predetermined length.

基礎型枠間隔保持用およびアンカーボルト保持用金物２０の両側には、地中杭３５との間を接続するターンバックルロープ３４により下向き方向の力が作用するようになっており、基礎型枠板４０、４０の上部を基礎型枠間隔保持用およびアンカーボルト保持用金物２０により下向きに押し付け、安定的に保持するようになっている。

図２〜４を参照しながら、基礎型枠間隔保持用およびアンカーボルト保持用金物２０を説明する。
基礎型枠間隔保持用およびアンカーボルト保持用金物２０は、基礎型枠板４０、４０上に架け渡されて載置されるベース板２１と、該ベース板２１の下側に固定され左右の基礎型枠板４０、４０の上端にそれぞれ嵌合する位置に設けられた一対の間隔保持部材２２、２２と、該ベース板２１の上側に立設されベース板と所定の間隔を有しかつ平行部を有するアンカーボルト保持板２５とを具備している。
ベース板２１、間隔保持部材２２およびアンカーボルト保持板２５は、それぞれ、金属板から形成されており、溶接等により固定されるもので、ベース板２１は、間隔保持部材２２およびアンカーボルト保持板２５の両部材を所定の位置に固定する役割を果たしている。
また、ベース板２１の両側にはターンバックル３４に接続されるバーを通すための孔３２、３２が穿設されている。 With reference to FIGS. 2 to 4, the base metal frame holding metal fixture 20 and anchor bolt holding hardware 20 will be described.
The base formwork interval holding and anchor bolt holding hardware 20 includes a base plate 21 that is placed on the base formwork plates 40 and 40 and placed on the lower side of the base plate 21. A pair of spacing members 22, 22 provided at positions where they are respectively fitted to the upper ends of the mold plates 40, 40, and standing parallel to the base plate that is erected on the upper side of the base plate 21. And an anchor bolt holding plate 25.
The base plate 21, the spacing member 22 and the anchor bolt retaining plate 25 are each formed of a metal plate and fixed by welding or the like. The base plate 21 is composed of the spacing member 22 and the anchor bolt retaining plate 25. The two members are fixed to a predetermined position.
Further, holes 32, 32 for passing a bar connected to the turnbuckle 34 are formed on both sides of the base plate 21.

間隔保持部材２２は、下向きに開口した略コ字状をしており、内側板２３より外側板２４を長く形成し、外側板２４は基部から先端に向けて外側にやや開いた傾斜状に設けられる。該略コ字状の大きさは基部において基礎型枠板４０の上部の幅とほぼ同じに、また、先端開口部においてやや大きく設定されている。
このため、基礎型枠板４０の上部に上方から間隔保持部材２２を嵌合させる場合、基礎型枠板４０の上部が外側板２４の傾斜面にガイドされるようにして略コ字状開口の基部まで嵌合する。その際、左右の間隔保持部材２２、２２の間隔は、内側板２３、２３の内側間寸法が基礎型枠板４０、４０の内側間寸法に一致するように設定されているので、両者が嵌合した時点では、基礎型枠板４０、４０は所定の間隔で保持されることになる。 The spacing member 22 has a substantially U-shape that opens downward, and the outer plate 24 is formed longer than the inner plate 23. The outer plate 24 is provided in an inclined shape that is slightly opened outward from the base toward the tip. It is done. The substantially U-shaped size is set to be substantially the same as the width of the upper portion of the basic mold plate 40 at the base and slightly larger at the tip opening.
For this reason, when the spacing member 22 is fitted to the upper part of the basic mold plate 40 from above, the upper part of the basic mold plate 40 is guided by the inclined surface of the outer plate 24 so that the substantially U-shaped opening is formed. Fit to the base. At that time, the distance between the left and right spacing members 22, 22 is set so that the inner dimension of the inner plates 23, 23 matches the inner dimension of the basic mold plates 40, 40. At the time of joining, the basic mold plates 40, 40 are held at a predetermined interval.

基礎型枠間隔保持用およびアンカーボルト保持用金物２０を基礎型枠板４０、４０上にしっかりと固定するため、釘あるいはネジを用いる場合がある。基礎型枠板４０が木製の場合は釘が用いられ、金属製の場合は基礎型枠板に予め形成されているネジ穴に螺合するネジが用いられる。このため、ベース板２１および間隔保持部材２２には覗き兼固定用の貫通孔３３が穿設されている。   A nail or a screw may be used in order to firmly fix the base formwork interval holding and anchor bolt holding hardware 20 on the base formwork plates 40 and 40. When the base mold plate 40 is made of wood, a nail is used, and when it is made of metal, a screw that is screwed into a screw hole formed in advance in the basic mold plate is used. For this reason, the base plate 21 and the spacing member 22 are provided with a through-hole 33 for peeping and fixing.

アンカーボルト保持板２５は、ベース板２１の上側かつ中央に位置して設けられるものであって、ベース板２１から垂直に立ち上がる両側板２６、２６と該両側板２６、２６間に延びベース板２１に平行な天板２７とから形成されている。
また、ベース板２１およびアンカーボルト保持板２５の天板２７にアンカーボルト２８を挿通するためのアンカーボルト挿通孔３０、３１がそれぞれ設けられている。 アンカーボルト２８は、通常、下端が曲げられたり、あるいは太く形成されているため、アンカーボルト挿通孔３０、３１の下側から上方に向けて挿通され、所定の位置でナット２９により固定される。 The anchor bolt holding plate 25 is provided on the upper side and the center of the base plate 21, and extends between the side plates 26, 26 rising vertically from the base plate 21 and the side plates 26, 26. The top plate 27 is parallel to the top plate 27.
Also, anchor bolt insertion holes 30 and 31 for inserting anchor bolts 28 are provided in the base plate 21 and the top plate 27 of the anchor bolt holding plate 25, respectively. Since the lower end of the anchor bolt 28 is usually bent or thick, the anchor bolt 28 is inserted upward from the lower side of the anchor bolt insertion holes 30 and 31 and is fixed by a nut 29 at a predetermined position.

ベース板２１とアンカーボルト保持板２５の天板２７との間隔はアンカーボルト２８を鉛直に保持する観点からは大きいことが望まれるが、アンカーボルト２８の上部をコンクリート基礎上面から上方に延出する長さに制約あることから、一定の適切な寸法に設定される。この間隔は、住宅用の基礎の場合、約５〜１０ｃｍの範囲が望ましい。   The distance between the base plate 21 and the top plate 27 of the anchor bolt holding plate 25 is desirably large from the viewpoint of holding the anchor bolt 28 vertically, but the upper portion of the anchor bolt 28 extends upward from the upper surface of the concrete foundation. Since there is a restriction on the length, it is set to a certain appropriate dimension. This spacing is preferably in the range of about 5-10 cm for residential foundations.

本発明の基礎型枠間隔保持用およびアンカーボルト保持用金物２０は以下の要領で簡単に設置することができる。
