Description

本発明は、構造物を吊り下げるための吊り金具を螺合する取付台座に関するものである。 The present invention relates to a mounting base for screwing a suspension fitting for suspending a structure.

例えば、洗車機等の構造物を工場で組み立てた後、運搬・輸送するためにその構造物を吊り下げてトラック等に積載したり設置場所で荷下ろしする必要がある。その際、構造物の天面四隅にアイボルト等の吊り金具を取り付けて、そのボルトにクレーンのフックを係止する方法が採られている。 For example, after assembling a structure such as a car wash machine in a factory, it is necessary to hang the structure and load it on a truck or unload it at an installation location for transportation and transportation. At that time, a method is employed in which hanging brackets such as eyebolts are attached to the four corners of the top surface of the structure, and the hooks of the crane are locked to the bolts.

さて、吊り金具を取り付ける取付台座として、特許文献１が知られている。特許文献１は、アイボルトを螺合するためのナットを１枚の金属板で包囲し、このナットを抜け止め・回り止めするための突起を加工することで形成されている。このような構成では、逆ハ字型に折曲した金属板にナットを取り付けてから、更にコ字型に折曲していき、取り付けたナットの周縁に当たる側面を内側にプレスして抜け止め・回り止め用の突起を形成するので、加工工数が多く手間が掛かるとともに、１枚の金属板であるためボルト螺合時に強度面での不安が残る。
特許第３１９９４４７号 Now, patent document 1 is known as an attachment base which attaches a hanging metal fitting. Patent Document 1 is formed by surrounding a nut for screwing an eyebolt with a single metal plate and processing a protrusion for preventing the nut from coming off and rotating. In such a configuration, after attaching a nut to a metal plate bent into an inverted C shape, it is further bent into a U shape, and the side that hits the periphery of the attached nut is pressed inward to prevent it from falling out. Since the rotation-preventing protrusion is formed, it takes a lot of processing steps, and since it is a single metal plate, there remains anxiety in terms of strength when the bolt is screwed.
Japanese Patent No. 31994447

本発明が解決しようとする課題は、加工工数を少なくし、ナット（もしくはボルト）を強固に保持することを可能とした吊り金具の取付台座を提供することにある。 The problem to be solved by the present invention is to provide a mounting base for a hanging metal fitting that can reduce the number of processing steps and can hold a nut (or bolt) firmly.

本発明は上記課題を解決するため、構造物に取付固定され、該構造物を吊り下げるための吊り金具を螺合する取付台座であって、この取付台座は、上面壁と左右側面壁の３面を有するコ字状の第１基材と、底面壁と左右側面壁の３面を有するコ字状の第２基材とを備え、第２基材を第１基材に内嵌する形状としてそれぞれ開放面を対向させた状態から組み付け可能とし、第２基材の左右側面壁端部にナットが嵌着する取付凹溝を形成し、第１基材の上面壁にナットのねじ孔と略同心のボルト挿通孔を開口し、第１及び第２基材を組み付けたとき、第２基材の取付凹溝に嵌着したナットが抜け止めされてボルト挿通孔と整合するものである。 In order to solve the above-mentioned problems, the present invention is a mounting base that is fixedly attached to a structure and that is screwed with a hanging metal fitting for hanging the structure. The mounting base includes an upper surface wall and left and right side walls. A U-shaped first base material having a surface, and a U-shaped second base material having three surfaces of a bottom wall and left and right side walls, and a shape in which the second base material is fitted into the first base material Can be assembled from the state in which the open surfaces are opposed to each other, and mounting concave grooves into which nuts are fitted are formed at the left and right side wall end portions of the second base material, and screw holes of the nut are formed on the upper surface wall of the first base material. When the first concentric bolt insertion hole is opened and the first and second base materials are assembled, the nut fitted in the mounting groove of the second base material is prevented from coming off and aligned with the bolt insertion hole.

また、構造物に取付固定され、該構造物を吊り下げるための吊り金具を螺合する取付台座であって、この取付台座は、上面壁と左右側面壁の３面を有するコ字状の第１基材と、底面壁と左右側面壁の３面を有するコ字状の第２基材とを備え、第２基材を第１基材に内嵌する形状としてそれぞれ開放面を対向させた状態から組み付け可能とし、第２基材の左右側面壁端部にボルトの頭部が嵌着する取付凹溝を形成し、第１基材の上面壁にボルトの軸部が貫通するボルト貫通孔を開口し、第１及び第２基材を組み付けたとき、第２基材の取付凹溝に嵌着したボルトが軸部をボルト貫通孔から突出させた状態で抜け止めされるものである。 The mounting base is fixedly attached to the structure and is screwed with a hanging metal fitting for hanging the structure. The mounting base is a U-shaped first plate having three surfaces, an upper surface wall and left and right side walls. 1 base material, and a U-shaped second base material having three surfaces of a bottom wall and left and right side walls, each having an open surface facing the second base material as a shape that fits inside the first base material. Bolt through-holes that can be assembled from the state, are formed with mounting grooves in which the heads of the bolts are fitted at the left and right side wall end portions of the second base material, and the shaft portion of the bolt penetrates the upper surface wall of the first base material When the first and second base materials are assembled, the bolts fitted in the mounting concave grooves of the second base material are prevented from coming off with the shaft portion protruding from the bolt through hole.

本発明によれば、吊り金具を取り付ける取付台座を、第１基材と第２基材とをナットもしくはボルトを挟持して嵌合する構成としたので、ナットもしくはボルトを回り止め・抜け止めするためのプレス加工等が不要となり、加工工数が軽減されるとともに、簡単な構成で吊り金具を螺合する六角ナットもしくは六角ボルトを強固に回り止め・抜け止めした状態で保持することができる。 According to the present invention, the mounting base to which the hanging bracket is attached has a configuration in which the first base material and the second base material are fitted to each other with the nut or the bolt interposed therebetween. Therefore, it is possible to hold the hexagon nut or the hexagon bolt, which is screwed to the suspension metal fitting, with a simple structure and firmly prevented from coming off.

以下、図面を用いて本発明の実施例について説明する。図１〜３は本発明の吊り金具の取付台座の組み立て手順を示している。
取付台座１は、下向きコ字型の上基材２と、該上基材２に内嵌する上向きコ字型の下基材３とで六角ナット４を挟持するように組み合わせて形成される。上基材２は、板厚ｔ（２．０ｍｍ程度）の金属板を下向きコ字状に折り曲げて上面壁２Ａと側面壁２Ｂ・２Ｃを形成しており、この上面壁２Ａの略中心にボルト挿通孔５を開口し、各側面壁２Ｂ・２Ｃに複数のねじ孔６を開口している。下基材３は、板厚ｔ（２．０ｍｍ程度）の金属板を上向きコ字状に折り曲げて底面壁３Ａと側面壁３Ｂ・３Ｃを形成しており、各側面壁３Ｂ・３Ｃの開口縁に六角ナット４が嵌着するナット取付凹溝７，７を形成するとともに、上基材２のねじ孔６に対応する複数のねじ孔８を開口している。 Embodiments of the present invention will be described below with reference to the drawings. 1-3 have shown the assembly procedure of the mounting base of the suspension metal fitting of this invention.
The mounting base 1 is formed by combining a downward U-shaped upper base material 2 and an upward U-shaped lower base material 3 fitted inside the upper base material 2 so as to sandwich a hexagon nut 4. The upper base 2 is formed by bending a metal plate having a thickness t (about 2.0 mm) downwardly into a U-shape to form an upper surface wall 2A and side walls 2B and 2C. Bolts are provided at substantially the center of the upper surface wall 2A. The insertion hole 5 is opened, and a plurality of screw holes 6 are opened in the side walls 2B and 2C. The lower base 3 is formed by bending a metal plate having a thickness t (about 2.0 mm) upward in a U-shape to form a bottom wall 3A and side walls 3B and 3C, and an opening edge of each side wall 3B and 3C. Nut mounting grooves 7 and 7 into which the hexagon nut 4 is fitted are formed, and a plurality of screw holes 8 corresponding to the screw holes 6 of the upper base 2 are opened.

ナット取付凹溝７，７は、両者間の距離Ｄが六角ナット４の平径ｓとほぼ同じであり、高さ寸法Ｈが六角ナット４の高さｈとほぼ同じであり、幅寸法Ｗが六角ナット４の平面幅ｗよりも大きく設定されている。これにより、六角ナット４は、ナット取付凹溝７，７に嵌着すると、幅方向及び高さ方向の突出がなく前後方向に僅かなガタを有した状態で回り止めされる。 The nut mounting grooves 7, 7 have a distance D between them that is substantially the same as the flat diameter s of the hex nut 4, a height dimension H that is substantially the same as a height h of the hex nut 4, and a width dimension W. It is set larger than the plane width w of the hexagon nut 4. As a result, when the hexagon nut 4 is fitted in the nut mounting grooves 7, 7, the hexagon nut 4 is prevented from rotating in a state where there is no protrusion in the width direction and the height direction and there is a slight backlash in the front-rear direction.

下基材３に六角ナット４を取り付けた後、上基材２を組み合わせると、下基材３が上基材２に内嵌され、六角ナット４が上基材２の上面壁２Ａ内面に当接して抜け止めされる。そして、上基材２の各側面壁２Ｂ・２Ｃに開口したねじ孔６と下基材３の各側面壁３Ｂ・３Ｃに開口したねじ孔８とが整合し、六角ナット４のねじ孔と上基材２のボルト挿通孔５とが整合するので、ねじ孔６とねじ孔８とにボルト９を挿通して上基材２と下基材３を連結した後、ボルト挿通孔５からアイボルト１０を挿通して六角ナット４に螺合する。 When the upper base material 2 is combined after the hexagon nut 4 is attached to the lower base material 3, the lower base material 3 is fitted into the upper base material 2, and the hexagon nut 4 contacts the inner surface of the upper surface wall 2A of the upper base material 2. It comes in contact and is prevented from coming off. And the screw hole 6 opened to each side wall 2B * 2C of the upper base material 2 and the screw hole 8 opened to each side wall 3B * 3C of the lower base material 3 match, and the screw hole of the hexagon nut 4 and the upper Since the bolt insertion hole 5 of the base material 2 is aligned, the bolt 9 is inserted into the screw hole 6 and the screw hole 8 to connect the upper base material 2 and the lower base material 3, and then the eye bolt 10 is passed through the bolt insertion hole 5. Is inserted into the hexagon nut 4.

こうして形成される取付台座１を構造物の四隅に取り付けて、取付台座１に螺合される吊り金具１０にクレーンワイヤーのフック等を引掛け、搬送等が行われる。構造物に取り付ける場合は、図５に示すように、取付面となる側壁面（ここでは２Ｃ・３Ｃ）に対し、アングル等のフレーム１１のねじ孔１２からボルト１３を挿通し、側壁面のねじ孔６・８を貫通して共締めすることで行われる。 The mounting base 1 formed in this way is attached to the four corners of the structure, and a crane wire hook or the like is hooked on the suspension fitting 10 that is screwed onto the mounting base 1 to carry and the like. When attaching to a structure, as shown in FIG. 5, a bolt 13 is inserted through a screw hole 12 of a frame 11 such as an angle into a side wall surface (2C, 3C in this case) serving as a mounting surface, and a screw on the side wall surface. This is done by penetrating the holes 6 and 8 together.

次に、六角ナット４に代わって、六角ボルトを取り付ける場合について説明する。
取付台座１の構成は、上述したものと同様であり、図５に示すように、下基材３のナット取付凹溝７，７に六角ボルト１４の頭部１４ａを嵌着し、上基材２のボルト挿通孔５から六角ボルト１４の軸部１４ｂを突出させることで取り付けられる。突出した六角ボルト１４の軸部１４ｂには、アイナット１５が螺合され、以下、上述同様に使用されるものである。 Next, a case where a hexagon bolt is attached instead of the hexagon nut 4 will be described.
The structure of the mounting base 1 is the same as that described above. As shown in FIG. 5, the head 14 a of the hexagon bolt 14 is fitted into the nut mounting grooves 7, 7 of the lower base 3, and the upper base It is attached by projecting the shaft portion 14 b of the hexagon bolt 14 from the second bolt insertion hole 5. An eye nut 15 is screwed onto the protruding shaft portion 14b of the hexagon bolt 14 and is used in the same manner as described above.

このような構成により、吊り金具（アイボルト・アイナット等）を取り付ける取付台座を簡単な構成としながらも、吊り金具を螺合する六角ナットもしくは六角ボルトを強固に回り止め・抜け止めした状態で保持することができる。尚、上記実施例では、上基材・下基材と表現し、吊り金具を取付台座の上方から螺合する構成で例示しているが、取付台座のボルト挿通孔が側面になるようにして吊り金具を螺合するようにしてもなんら本発明と代わるものではない。また、ボルト挿通孔を下基材側に開口してもよい。 With such a configuration, the mounting base to which the hanging bracket (eye bolt, eye nut, etc.) is attached has a simple configuration, but the hexagon nut or hexagon bolt to which the hanging bracket is screwed is securely held and prevented from coming off. be able to. In addition, in the said Example, although expressed as an upper base material and a lower base material and illustrated by the structure which screws a suspension metal fitting from the upper direction of a mounting base, it is made so that the bolt insertion hole of a mounting base may become a side surface. Even if the suspension fitting is screwed together, it does not replace the present invention. Further, the bolt insertion hole may be opened on the lower base material side.
