[Prior Art]

図３に示すように、グレーチング１は、長手方向にメインバー２と称する荷重支持用の板部材を等間隔に配列し、短手方向にクロスバー３と称するメインバーの構造精度を保持する棒材を等間隔に配列してなる長方形状の格子金属板である。このようなグレーチングを、例えば、工場等の床板や階段の踏板等に使用する場合は、溝形等の各種形鋼にて形成される支持架台４にグレーチングを固定する必要があり、従来より各種の専用固定金具が使用されてきた。 As shown in FIG. 3, the grating 1 is a bar in which load supporting plate members called main bars 2 are arranged at equal intervals in the longitudinal direction, and structural accuracy of the main bar called cross bars 3 is maintained in the lateral direction. It is a rectangular grid metal plate made by arranging materials at equal intervals. When such a grating is used, for example, on a floorboard of a factory or a stepboard of a stairway, it is necessary to fix the grating to a support frame 4 formed of various shaped steels such as a groove, and it is necessary to fix the grating to a conventional type. Dedicated fixing brackets have been used.

【０００３】図３に示す固定金具は、サドルクリップ式と称されるものであり、架台４上に支持されたグレーチング１の互いに隣合う２本のメインバー２，２に、これを跨ぐ形のサドルクリップ５を取り付け、該サドルクリップと架台４とを、両者を貫通するボルト６とナット６′で締着することにより、グレーチング１を架台４に固定する型式のものである。The fixing metal fitting shown in FIG. 3 is called a saddle clip type, and is formed by straddling two main bars 2 and 2 adjacent to each other of a grating 1 supported on a frame 4. This is a type in which the grating 1 is fixed to the gantry 4 by attaching the saddle clip 5 and fixing the saddle clip and the gantry 4 with bolts 6 and nuts 6 ′ that penetrate them.

【０００４】また、図４に示す固定金具はフックボルト式と称されるものであり、先端７ａを鉤状に曲げてなるフックボルト７の先端を架台４上に支持されたグレーチング１のメインバー２に引掛け、尾端部７ｂを架台４の下面側へ貫通させて該尾端部７ｂに架台４の下面側よりナット７′を締着することにより、グレーチング１を架台４に固定する型式のものである。Further, the fixing metal fitting shown in FIG. 4 is called a hook bolt type, and the main bar of the grating 1 in which the tip of the hook bolt 7 formed by bending the tip 7a into a hook shape is supported on the frame 4. A type in which the grating 1 is fixed to the pedestal 4 by hooking the tail end portion 7b to the lower surface side of the pedestal 4 and tightening the nut 7'from the lower surface side of the pedestal 4 to the tail end portion 7b. belongs to.

【０００５】[0005]

[Problems to be solved by the device]

しかしながら、上記図３、図４に示した従来の固定金具は、いずれも現場において架台４にボルト６，７を通すための貫通孔を設けなければならず、またボルト・ナットの締着作業を必要とする等、取付けが面倒でかなりの時間を要するという問題があった。 However, in both of the conventional fixing fittings shown in FIGS. 3 and 4, through holes for passing the bolts 6 and 7 must be provided in the gantry 4 in the field, and the bolts and nuts must be tightened. There was a problem that installation was troublesome and required a considerable amount of time, such as requiring wearing work.

【０００６】本考案は、このような問題を解決するためになされたものであり、架台に貫通孔を設けたり、ボルト・ナットの締着作業を行う必要がなく、ワンタッチでグレーチングを架台に固定することができる金具の提供を目的とする。The present invention has been made in order to solve such a problem, and does not require a through hole in the mount or the need for tightening bolts and nuts. The purpose is to provide a metal fitting that can be fixed.

[Means for Solving the Problems]

上記目的を達成する本考案のグレーチング用止め金具は、Ｔ字形板の水平板部９を垂直板部１０に対して前方へほぼ直角に折曲するとともに、垂直板部１０の下端１１を前方へ鉤状に折曲してなり、その水平板部９がグレーチング１の互いに隣合う平行なメインバー２，２の上面に掛合し、上記メインバー２，２間に垂下する垂直板部１０の下端１１がグレーチング１を支持する架台４の下端角部に掛止するよう構成されている。 In the grating stopper of the present invention which achieves the above object, the horizontal plate portion 9 of the T-shaped plate is bent forward at a right angle to the vertical plate portion 10, and the lower end 11 of the vertical plate portion 10 is moved forward. The vertical plate portion 10 is bent in a hook shape, and its horizontal plate portion 9 is hooked on the upper surfaces of the parallel main bars 2 and 2 of the grating 1 which are adjacent to each other and hangs down between the main bars 2 and 2. The lower end 11 of the rack is configured to be hooked on the lower corner of the pedestal 4 supporting the grating 1.

【０００８】[0008]

[Action]

上記構成よりなる金具は、その水平板部９をグレーチング１のメインバー２，２上に掛合し、メインバー２，２間より垂下する垂直板部１０の鉤状下端１１を架台４の下面に掛止すると、水平板部９と垂直板部下端１１との間で、グレーチング１とこれを支持する架台４とが一体に挟持される。これによりグレーチング１は架台４に強く固定される。したがって、金具の取り付けに際して、ボルト・ナットの締着作業が不要であり、架台にボルト孔を設ける必要もない。 In the metal fitting having the above-described structure, the horizontal plate portion 9 is hooked on the main bars 2 and 2 of the grating 1, and the hook-shaped lower end 11 of the vertical plate portion 10 hanging between the main bars 2 and 2 is placed on the lower surface of the gantry 4. When latched, the grating 1 and the frame 4 supporting the grating 1 are integrally sandwiched between the horizontal plate portion 9 and the lower end 11 of the vertical plate portion. As a result, the grating 1 is firmly fixed to the mount 4. Therefore, it is not necessary to tighten bolts and nuts when mounting the metal fittings, and it is not necessary to provide bolt holes in the frame.

【０００９】以下、本考案の実施例について説明する。An embodiment of the present invention will be described below.

【００１０】[0010]

【Example】

図１において、１はグレーチング、４はグレーチングの端部を支持する山形鋼により形成された架台、８₁，８₂は、いずれもグレーチング１を架台４に固定する本考案の金具である。In FIG. 1, 1 is a grating, 4 is a mount made of chevron steel that supports the ends of the grating, and 8 ₁ and 8 ₂ are metal fittings of the present invention for fixing the grating 1 to the mount 4.

【００１１】これらの金具８₁，８₂は、厚さ約1.５ｍｍのステンレスより切り出したＴ字形板の水平板部９を垂直板部１０に対して前方へ直角に折り曲げるとともに、垂直板部１０の下端１１を前方へ鉤状に折曲形成したものである。These metal fittings 8 ₁ and 8 ₂ are formed by bending a horizontal plate portion 9 of a T-shaped plate, which is cut out from stainless steel having a thickness of about 1.5 mm, at a right angle to the vertical plate portion 10 at a right angle, and The lower end 11 of the portion 10 is bent forward to form a hook shape.

【００１２】すなわち、図２に示すように、水平板部９の長手幅Ｗ₁は、グレーチング１の互いに隣合う２本のメインバー２，２の間隙Ｐよりも大きく、その両端部９ａ，９ｂが上記メインバー２，２の上面に掛合されるように形成されている。この水平板部９は、図示例のように、その両端部９ａ，９ｂを、側方へ延長して下方へ折り曲げメインバー２，２の上面から側部にまで回り込むような形に形成しておいてもよい。That is, as shown in FIG. 2, the longitudinal width W ₁ of the horizontal plate portion 9 is larger than the gap P between two main bars 2 and 2 of the grating 1 which are adjacent to each other, and both end portions 9a and 9b thereof. Are formed so as to be engaged with the upper surfaces of the main bars 2 and 2. The horizontal plate portion 9 is formed in such a shape that both end portions 9a and 9b thereof are laterally extended and bent downward as shown in the illustrated example so as to extend from the upper surfaces of the main bars 2 and 2 to the lateral portions. You may come.

【００１３】垂直板部１０は、メインバー２，２間に余裕をもって嵌め込めるよう、その幅Ｗ₂はメインバー２，２の間隙Ｐよりも若干小さく形成してある。また、垂直板部の長さ、すなわち水平板部９の折曲部から下端１１の折曲部までの長さＬ（図１参照）は、メインバー２の上面から架台４の下端までの長さにほぼ等しく形成されている。すなわち、金具８₁の場合では垂直板部１０の前記長さＬは、メインバー２の上面から架台４である山形鋼のウエブ４ａ下端までの長さにほぼ等しく形成され、金具８₂の場合では、垂直板部１０の前記長さＬは、メインバー２の上面から架台４である山形鋼のフランジ４ｂ下面までの長さにほぼ等しく形成されている。The width W ₂ of the vertical plate portion 10 is formed to be slightly smaller than the gap P between the main bars 2 and 2 so that the vertical plate portion 10 can be fitted between the main bars 2 and 2 with a margin. Further, the length of the vertical plate portion, that is, the length L from the bent portion of the horizontal plate portion 9 to the bent portion of the lower end 11 (see FIG. 1) is the length from the upper surface of the main bar 2 to the lower end of the gantry 4. Is formed almost equal to That is, the length L of the vertical plate portion 10 in the case of fitting 8 _1, from the upper surface of the main members 2 to webs 4a lower end of angle irons are frame 4 is substantially equal rather formed in the length, fitting 8 ₂ In this case, the length L of the vertical plate portion 10 is formed substantially equal to the length from the upper surface of the main bar 2 to the lower surface of the flange 4b of the angle steel which is the pedestal 4.

【００１４】垂直板部１０の下端１１は、約２ｃｍ程度が前方へ鉤状に折り曲げてあり、架台４の下端に掛止するようになっている。下端４の折り曲げ角度（θ）は抜け止めを考慮して９０°以上とするのがよく、図示例の場合は約１２０°の角度で折り曲げてある。また、下端１１の先端部分１１′は下方へ緩く彎曲させてあり、架台４に掛止する際のすべり面に形成してある。この下端１１は、その先端部分１１′を架台４の下端角部に当てがい、メインバー２，２に掛けた水平板部９を支点として架台４方向にクランプ（万力）等で所要の押圧力（先端部分１１′が下方へ押し開かれる程度の力）を加えることによって、架台４の下端角部に掛止される。A lower end 11 of the vertical plate portion 10 is bent forward in a hook shape by about 2 cm, and is hooked on the lower end of the gantry 4. The bending angle (θ) of the lower end 4 is preferably 90 ° or more in consideration of the prevention of coming off, and in the illustrated example, it is bent at an angle of about 120 °. Further, the tip portion 11 ′ of the lower end 11 is bent downward gently and is formed on a sliding surface when hooked on the pedestal 4. The lower end 11 of the lower end 11 is applied to the corner of the lower end of the gantry 4, and the horizontal plate 9 hung on the main bars 2 and 2 is used as a fulcrum to push the pedestal 4 in a desired direction with a clamp (vice). By applying pressure (a force that pushes and opens the tip portion 11 ′ downward), the tip portion 11 ′ is hooked on the lower end corner portion of the gantry 4.

[Effect of the device]

以上に説明したとおり、本考案のグレーチング用止め金具は、その水平板部をグレーチングのメインバーに掛合し、垂直板部の下端を架台の下端に掛止するだけで、グレーチングと架台とを一体に強く固定することができるから、従来のように現場にて架台にボルト孔を設ける必要がなく、またボルト・ナットの締着作業を行う必要もない。したがって、この種の固定作業を極めて簡単かつ迅速に行うことができる。 As described above, the grating stopper of the present invention is such that the horizontal plate part is engaged with the main bar of the grating, and the lower end of the vertical plate part is engaged with the lower end of the gantry, so that the grating and the gantry are connected. Since they can be firmly fixed together, there is no need to provide bolt holes in the gantry at the site as in the past, and there is no need to perform bolt and nut tightening work. Therefore, this type of fixing work can be performed extremely easily and quickly.
