Description

本考案は、鉄骨構造物等を取り付けボルトでコンクリート基礎に定着するアンカープレートに関する。 The present invention relates to an anchor plate for fixing a steel structure or the like to a concrete foundation with mounting bolts.

鉄骨構造物等を取り付けボルトでコンクリート基礎に定着するアンカープレートには、図４に示すように、プレート本体５１に貫通孔５２を設け、プレート本体５１の貫通孔５２を設けた部位の裏面側に、コンクリート基礎に埋め込まれる定着ナット５３を溶接で取り付けて、表面側から貫通孔５２に挿入される取り付けボルトを定着ナット５３に螺合するようにしたものがある。定着ナット５３を複数個取り付けたものもある。 As shown in FIG. 4, an anchor plate for fixing a steel structure or the like to a concrete foundation with mounting bolts is provided with a through hole 52 in the plate body 51 and on the back side of the portion of the plate body 51 where the through hole 52 is provided. A fixing nut 53 embedded in a concrete foundation is attached by welding, and a fixing bolt inserted into a through hole 52 from the surface side is screwed into the fixing nut 53. Some have a plurality of fixing nuts 53 attached thereto.

上述した従来のアンカープレートは、定着ナットを溶接で取り付けているので、その熱応力によってプレート本体に波打ちやうねり等の熱ひずみが生じる問題がある。また、定着ナットを裏面側に溶接するためにアンカープレートを反転する必要があり、定着ナットの取り付けに手間がかかる問題もある。 Since the conventional anchor plate described above has a fixing nut attached thereto by welding, there is a problem in that the thermal stress such as undulation and undulation occurs in the plate body due to the thermal stress. Further, in order to weld the fixing nut to the back surface side, it is necessary to reverse the anchor plate, and there is a problem that it takes time to install the fixing nut.

そこで、本考案の課題は、プレート本体に熱ひずみを生じさせることなく、定着ナットを簡単に取り付けることができるようにすることである。 Therefore, an object of the present invention is to make it possible to easily attach a fixing nut without causing thermal strain in the plate body.

上記の課題を解決するために、本考案は、プレート本体に少なくとも１つの貫通孔を設け、このプレート本体の貫通孔を設けた部位の裏面側に、コンクリート基礎に埋め込まれる定着ナットを取り付けて、表面側から前記貫通孔に挿入される取り付けボルトを前記定着ナットのねじ孔に螺合するようにしたアンカープレートにおいて、前記貫通孔に表面側が拡径する段差部を設け、前記定着ナットの前記プレート本体に取り付けられる基端部に、前記ねじ孔と逆ねじでその谷径よりも大径の逆ねじ孔を設けて、前記プレート本体の貫通孔の段差部に係合するように拡径する頭部と、前記取り付けボルトを通す中心孔とを有し、前記定着ナットの逆ねじ孔に螺合する逆ねじ部を設けたねじカプラーを、前記貫通孔の表面側から定着ナットの逆ねじ孔に螺着して、前記定着ナットを前記プレート本体に取り付けた構成を採用した。 In order to solve the above-mentioned problems, the present invention provides at least one through hole in the plate body, and attaches a fixing nut embedded in the concrete foundation to the back side of the portion where the through hole of the plate body is provided. An anchor plate in which a mounting bolt to be inserted into the through hole from the front side is screwed into a screw hole of the fixing nut is provided with a step portion whose diameter is enlarged on the surface side in the through hole, and the plate of the fixing nut A head having a reverse screw hole larger than the root diameter of the screw hole and reverse screw provided at the base end portion attached to the main body, and expanding the diameter so as to engage with the step portion of the through hole of the plate main body. And a screw coupler provided with a reverse thread portion that is screwed into the reverse screw hole of the fixing nut, and a reverse screw of the fixing nut from the surface side of the through hole. And screwed into the hole, adopting a structure fitted with the fixing nut to the plate body.

すなわち、プレート本体の貫通孔に表面側が拡径する段差部を設け、定着ナットの取り付け側の基端部に、ねじ孔と逆ねじでその谷径よりも大径の逆ねじ孔を設けて、貫通孔の段差部に係合する頭部と、取り付けボルトを通す中心孔とを有し、定着ナットの逆ねじ孔に螺合する逆ねじ部を設けたねじカプラーを、貫通孔の表面側から定着ナットの逆ねじ孔に螺着することにより、プレート本体に熱ひずみを生じさせることなく、かつ、プレート本体を反転させずに定着ナットを簡単に取り付けることができるようにした。 That is, a stepped portion whose diameter is enlarged on the surface side is provided in the through hole of the plate main body, and a reverse screw hole having a diameter larger than the valley diameter is provided at the base end portion on the attachment side of the fixing nut with a screw hole and a reverse screw, A screw coupler having a head portion that engages with a step portion of the through hole and a center hole through which the mounting bolt is passed, and a reverse screw portion that is screwed into the reverse screw hole of the fixing nut is provided from the surface side of the through hole. By screwing into the reverse screw hole of the fixing nut, the fixing nut can be easily attached without causing thermal strain in the plate main body and without inverting the plate main body.

前記定着ナットのねじ孔の先端側に、コンクリート基礎に埋め込まれるアンカーボルトを螺着することにより、アンカー効果を高めることができる。 The anchor effect can be enhanced by screwing an anchor bolt embedded in the concrete foundation to the tip side of the screw hole of the fixing nut.

本考案のアンカープレートは、プレート本体の貫通孔に表面側が拡径する段差部を設け、定着ナットの取り付け側の基端部に、ねじ孔と逆ねじでその谷径よりも大径の逆ねじ孔を設けて、貫通孔の段差部に係合する頭部と、取り付けボルトを通す中心孔とを有し、定着ナットの逆ねじ孔に螺合する逆ねじ部を設けたねじカプラーを、貫通孔の表面側から定着ナットの逆ねじ孔に螺着するようにしたので、プレート本体に熱ひずみを生じさせることなく、定着ナットを簡単に取り付けることができる。 The anchor plate of the present invention is provided with a stepped portion whose diameter is enlarged on the surface side in the through hole of the plate body, and a reverse screw having a larger diameter than the root diameter thereof by a screw hole and a reverse screw at the base end portion on the fixing nut mounting side. A screw coupler that has a head that engages with the stepped portion of the through hole and a center hole through which the mounting bolt passes and that has a reverse screw portion that engages with the reverse screw hole of the fixing nut is provided. Since the screw is screwed into the reverse screw hole of the fixing nut from the surface side of the hole, the fixing nut can be easily attached without causing thermal strain in the plate body.

以下、図面に基づき、本考案の実施形態を説明する。このアンカープレートは、図１に示すように、プレート本体１に表面側が拡径する段差部２ａを有する貫通孔２を設け、プレート本体１の貫通孔２を設けた部位の裏面側に、コンクリート基礎２１に埋め込まれる定着ナット３をねじカプラー４で取り付けたものであり、定着ナット３のねじ孔３ａに取り付けボルト２２を螺合して、鉄骨構造物等の被定着物２３を定着するようになっている。定着ナット３のねじ孔３ａの先端側には、コンクリート基礎２１に埋め込まれるアンカーボルト５が螺着され、ロックナット６で突出量を調節されるようになっている。
