Description
【０００１】[0001]
本考案は、予めコンクリート中に埋め込んでおき、カーテンウォール・各種配 管・付帯設備などの吊り下げ・支持・固定などに利用されるコンクリート埋め込 み金具に関する。 The present invention relates to a concrete-embedded metal fitting that is previously embedded in concrete and is used for suspending, supporting, and fixing curtain walls, various pipes, and auxiliary equipment.
【０００２】[0002]
従来、コンクリート埋め込み金具として普及しているものは、図７に示すよう に、内側に雌ネジが形成されている金具本体Ａと、端部にフックが形成されてい る係止部材Ｂとで構成されており、係止部材Ｂを金具本体Ａに一定の深さだけ螺 合した後、金具本体Ａの外側からプレス打ちを行ってネジ山を変形させることに より緩み止め加工を行っている構成である。 As shown in FIG. 7, conventionally, a concrete embedded metal fitting has a metal fitting body A having an internal thread formed therein and a locking member B having a hook formed at an end thereof. The locking member B is screwed to the metal fitting body A to a certain depth, and then press-fitting is performed from the outside of the metal fitting body A to deform the screw threads to prevent the loosening. Is.
【０００３】[0003]
コンクリート埋め込み金具は、型枠に取り付けた後、コンクリートの打設を行 い、養生を待って型枠の取り外しによりコンクリート中に残存するように施工さ れる。そこで、コンクリート中に埋め込まれた金具は、水分の影響で腐食し易い ために十分なメッキ加工が必要である。然しながら、図示した従来のタイプのコ ンクリート埋め込み金具では、金具本体Ａと係止部材Ｂとを合体させる以前にそ れぞれにメッキ加工を行うと、プレス加工により、金具本体Ａの外側及び内側の ネジ部分のメッキが剥れてしまい、この部分から腐食が進行する虞があり、また 逆に、金具本体Ａと係止部材Ｂとを合体させプレス加工を行った後にメッキ加工 を行うようにすると、ネジ部分に対するメッキ加工が不十分となり、この部分か ら腐食が進行する虞がある。 The concrete embedding metal fittings are installed in the formwork, then the concrete is placed, and after the curing, the formwork is removed so that the metal remains in the concrete. Therefore, metal fittings embedded in concrete are apt to corrode due to the influence of water, so sufficient plating is necessary. However, in the case of the conventional type concrete embedded metal fitting shown in the drawings, when plating is performed on the metal fitting body A and the locking member B before the metal fitting body A and the locking member B are combined, the outer and inner sides of the metal fitting body A are pressed by press working. There is a risk that the plating of the screw part will peel off and corrosion will progress from this part. Conversely, the metal fitting body A and the locking member B should be combined and press-worked before plating. Then, the plating process on the screw part becomes insufficient, and there is a risk that corrosion will progress from this part.
【０００４】 更に、上記した従来のコンクリート埋め込み金具では、プレス加工が必要な分 だけ製造工程が多く、製造コストの上昇を招く結果となっている。Further, in the above-mentioned conventional concrete-embedded metal fitting, the number of manufacturing steps is increased by the amount required for press working, resulting in an increase in manufacturing cost.
【０００５】 上記から明らかなように、本考案は、メッキ加工に悪影響を与えることのない 緩み止め機構を有するコンクリート埋め込み金具を明らかにすることを目的とす るものであり、本考案の他の目的は、プレス加工を必要とした従来の製品と比較 して製造コストの低減化を計ることが可能であるコンクリート埋め込み金具を明 らかにすることである。As is apparent from the above, the present invention aims to clarify a concrete-embedded metal fitting having a locking mechanism that does not adversely affect the plating process. The purpose is to clarify a concrete-embedded metal fitting that can reduce manufacturing costs compared to conventional products that require pressing.

本考案に係るコンクリート埋め込み金具は、内側に雌ネジが形成されている筒 状体であり、その頭部の内側端部には環状に切り欠きが形成されている金具本体 と、この金具本体の頭部の切り欠きに組み込まれるものであり、弾性を有する合 成樹脂製の環状の中子と、頭部にフックが、脚部に雄ネジが形成されており、こ の雄ネジの終端に続いて滑り止めが形成されている係止部材とから成り、前記係 止部材を前記金具本体に螺合させたとき、前記中子が前記係止部材の滑り止めに 係合して前記金具本体の頭部の切り欠きに圧着され前記係止部材と前記金具本体 との合体の緩みが防止される構成を有すること、を特徴とする。 The concrete-embedded metal fitting according to the present invention is a tubular body having a female screw formed on the inside thereof, and a metal fitting main body having an annular notch formed on the inner end portion of the head thereof, and a metal fitting main body of the metal fitting. It is installed in the notch of the head, has an annular core made of elastic synthetic resin, a hook on the head, and a male screw on the leg, and at the end of this male screw. Then, when the locking member is screwed onto the metal fitting body, the core engages with the non-slip of the locking member and the metal fitting body is formed. It has a structure in which it is crimped to the notch of the head to prevent loosening of the engagement of the locking member and the metal fitting body.
【０００７】[0007]
次に、本考案の具体的構成を添付の図面に従って詳細に説明する。 図１において、金具本体１０の内側には雌ネジ１１が形成されており、外周に は、各種形状の係止部１２が固着されている。金具本体１０の頭部１３の内側に は、テーパー状の切り欠き１４が形成されている。 Next, a specific configuration of the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, a female screw 11 is formed inside the metal fitting body 10, and a locking portion 12 of various shapes is fixed to the outer circumference. A tapered notch 14 is formed inside the head 13 of the metal fitting body 10.
【０００８】 他方、係止部材２０は、その頭部にフック２１が形成されており、脚部側には 一定の深さで雄ネジ２２が形成されており、この雄ネジ２２に続いて様々な凹凸 形状で構成される滑り止め２３が形成されている。On the other hand, the locking member 20 has a hook 21 formed on the head thereof, and a male screw 22 is formed on the leg side at a constant depth. An anti-slip 23 is formed which has an irregular shape.
【０００９】 ３０は、弾性を有する合成樹脂材で形成される環状の中子であり、上記した金 具本体１０の頭部１３に形成されているテーパー状の切り欠き１４に組み込まれ る。この中子３０の内径は、係止部材２０の雄ネジ２２の外径よりも大きく、滑 り止め２３の外径よりも若干小さく構成されている。Reference numeral 30 denotes an annular core made of an elastic synthetic resin material, which is incorporated in the tapered notch 14 formed in the head 13 of the metal body 10 described above. The inner diameter of the core 30 is larger than the outer diameter of the male screw 22 of the locking member 20 and slightly smaller than the outer diameter of the antiskid 23.
【００１０】 この中子３０の断面形状は、図に示すように、テーパー状の切り欠き１４に対 応したテーパー状とすることが好ましいが、全体に等しい肉厚のものであっても よい。As shown in the figure, the cross-sectional shape of the core 30 is preferably a tapered shape corresponding to the tapered notch 14, but the core 30 may have the same thickness as the whole.
【００１１】 更に、中子３０を形成する材質として粘着性を有する材料を利用することも好 ましく、また、アッセンブリーに際して接着剤などを利用する態様も本考案に包 含される。Further, it is also preferable to use a material having an adhesive property as a material for forming the core 30, and the present invention also includes a mode in which an adhesive or the like is used at the time of assembly.
【００１２】 ４０は、金具本体１０の雌ネジ１１に取り付けられる吊り下げ（取り付け）ボ ルトである。Reference numeral 40 denotes a suspending (attaching) bolt which is attached to the female screw 11 of the metal fitting body 10.
【００１３】 金具本体１０と係止部材２０とを合体させるには、先ず、中子３０を金具本体 １０の頭部のテーパー状の切り欠き１３に嵌挿させておき、次いで、係止部材２ ０を脚部側から挿入してネジ機構に沿って回転させる。係止部材２０が、その雄 ネジ２２が形成されている部分まで金具本体１０の雌ネジ１１に係合されると、 滑り止め２３が中子３０に当接してこれを膨出させるので、中子３０は、テーパ ー状の切り欠き１３の壁面に圧着することになり、係止部材２０の緩みが防止さ れる。In order to combine the metal fitting body 10 and the locking member 20, first, the core 30 is fitted and inserted into the tapered notch 13 of the head of the metal fitting body 10, and then the locking member 2 Insert 0 from the leg side and rotate along the screw mechanism. When the locking member 20 is engaged with the female screw 11 of the metal fitting body 10 up to the portion where the male screw 22 is formed, the non-slip 23 abuts the core 30 and swells the core 30. The child 30 is crimped to the wall surface of the tapered notch 13, so that the locking member 20 is prevented from loosening.
【００１４】 尚、アッセンブリーに際して予め中子３０を係止部材２０の滑り止め２３の部 分に嵌め込んでおく態様も本考案に包含される。It is to be noted that the present invention also includes a mode in which the core 30 is fitted in advance to the portion of the non-slip 23 of the locking member 20 at the time of assembly.
【００１５】 図２に示すように、中子３０の脱落を防止するためには、テーパー状の切り欠 き１４の底部に、環状溝１５を設けておくことが好ましく、更に、中子３０の側 面に、前記環状溝１５に嵌挿される凸部３１を形成しておくことも好ましい態様 である。As shown in FIG. 2, in order to prevent the core 30 from falling off, it is preferable to provide an annular groove 15 at the bottom of the tapered cutout 14. It is also a preferable aspect to form a convex portion 31 to be fitted into the annular groove 15 on the side surface.
【００１６】 図３に示すように、テーパー状の切り欠き１４に代えて、単なる垂直な切り欠 き１６とする態様、このような切り欠き１６に加えて環状溝１７を設ける態様、 図４に示すように、逆テーパー状の切り欠き１８とする態様も本考案に包含され る。As shown in FIG. 3, the tapered notch 14 is replaced by a simple vertical notch 16, a mode in which an annular groove 17 is provided in addition to such notch 16, and FIG. As shown, an embodiment in which the notch 18 having an inverse tapered shape is included in the present invention.
【００１７】 係止部材２０に形成される滑り止め２３は、図５に示すように、様々な凹凸形 状で形成することが可能である。これらの滑り止め２３は、プレス加工などで容 易に形成することができる。The anti-slip 23 formed on the locking member 20 can be formed in various irregular shapes as shown in FIG. These slip stoppers 23 can be easily formed by pressing or the like.
【００１８】 滑り止め２３の外径寸法は、雄ネジ２２の外径寸法よりも大であることが好ま しい。The outer diameter dimension of the slip stopper 23 is preferably larger than the outer diameter dimension of the male screw 22.
【００１９】 また、図６に示すように、別個に形成した滑り止め部材２４を取り付ける態様 であってもよい。Further, as shown in FIG. 6, a separately formed anti-slip member 24 may be attached.
【００２０】[0020]
本考案のコンクリート埋め込み金具は、上記のように構成されており、金具本 体１０の頭部１３に配置される中子３０を係止部材２０の滑り止め２３によりテ ーパー状の切り欠き１４に強固に圧着させるので、係止部材２０は金具本体１０ に対して緩むことがない。従って、本考案の構成によれば、金具本体１０及び係 止部材２０のそれぞれをメッキ加工した後にアッセンブリーしても、従来製品の 如きプレス加工を行う必要がないので、メッキが剥されてしまう虞がなく、腐食 が有効に防止されるので、長期間の使用に耐えることができ頭記した課題が解決 される。 The concrete-embedded metal fitting of the present invention is configured as described above, and the core 30 arranged on the head 13 of the metal fitting body 10 is made into the taper-shaped notch 14 by the non-slip 23 of the locking member 20. Since it is firmly crimped, the locking member 20 does not loosen with respect to the metal fitting body 10. Therefore, according to the configuration of the present invention, even if the metal fitting body 10 and the locking member 20 are assembled after being plated, there is no need to perform the pressing work as in the conventional product, and the plating may be peeled off. Since it does not exist and corrosion is effectively prevented, it can withstand long-term use and solve the above-mentioned problems.
【００２１】 更に、本考案の構成によれば、従来製品に比較し、アッセンブリーの後でのプ レス加工を必要としない分だけ製造コストの低減化を計ることが可能である。Further, according to the configuration of the present invention, it is possible to reduce the manufacturing cost as compared with the conventional product because the press processing after the assembly is not required.
