Description

本発明は、建築用の吊りボルトを吊り下げるための吊り金具の、形鋼への取付状態を補強する吊り金具取付用補助具に関するものである。 The present invention relates to a suspension fitting attaching auxiliary tool that reinforces the attachment state of a hanging fitting for hanging a construction hanging bolt to a shape steel.

建築用の吊りボルト17を吊り下げるための吊り金具４は、例えば、下記特許文献１や図４〜図６に示すように、金具本体18の前側の中ほどにＨ形鋼１Ａなどの形鋼１のフランジ部２を挿入配設し得る挿入配設部19が設けられ、この挿入配設部19の下側に、この挿入配設部19に挿入配設したフランジ部２を支承する支承部20が設けられ、この支承部20に支承されたフランジ部２を締付圧接固定する締付機構３としての締付ボルト３が金具本体18の上部に縦設状態に螺着されていて、金具本体18の上部より突出するこの締付ボルト３のボルト頭部３Ａを回動締付操作すると、締付ボルト３のボルト先端が前記挿入配設部19に進出してこの挿入配設部19で前記支承部20に支承された形鋼１のフランジ部２を締付圧接固定するように構成されている。 For example, as shown in the following Patent Document 1 and FIGS. 4 to 6, a hanging metal fitting 4 for suspending a building hanging bolt 17 is shaped steel such as H-section steel 1A in the middle of the front side of the metal fitting body 18. An insertion arrangement portion 19 into which one flange portion 2 can be inserted and arranged is provided, and a support portion for supporting the flange portion 2 inserted and arranged in the insertion arrangement portion 19 below the insertion arrangement portion 19. 20 is provided, and a fastening bolt 3 as a fastening mechanism 3 for fastening and fixing the flange portion 2 supported by the support portion 20 is screwed to the upper portion of the bracket body 18 in a vertically installed state. When the bolt head 3A of the tightening bolt 3 protruding from the upper portion of the main body 18 is rotated and tightened, the bolt tip of the tightening bolt 3 advances into the insertion placement portion 19 and the insertion placement portion 19 The flange portion 2 of the structural steel 1 supported by the support portion 20 is configured to be fixed by pressure contact.

また、金具本体18の下部には、取付孔21が形成されていてこの取付孔21に吊りボルト17を垂設状態に取付できるように構成されているが、金具本体18の上部にも取付孔21が形成されていて、金具本体18（吊り金具４）を上下逆向きにして形鋼１に取付固定しても吊りボルト17を垂設できるように構成されている。 In addition, a mounting hole 21 is formed in the lower part of the metal fitting body 18 so that the suspension bolt 17 can be attached to the mounting hole 21 in a suspended state. 21 is formed so that the suspension bolt 17 can be suspended even if the bracket body 18 (the suspension bracket 4) is turned upside down and fixed to the shape steel 1.

ところで、このような吊り金具４は、形鋼１の水平フランジ部２を横方向から挿入配設部19に挿入して締付固定する構成上、横方向に荷重が作用した場合に脱落し易い懸念がある。 By the way, such a hanging metal fitting 4 is easy to drop off when a load is applied in the lateral direction because the horizontal flange portion 2 of the shape steel 1 is inserted into the insertion arrangement portion 19 from the lateral direction and fastened and fixed. There are concerns.

そこで、下記特許文献２のような補助金具を併用して吊り金具４の形鋼１の水平フランジ部２への固定強度を補強することが行われている。 Therefore, an auxiliary metal fitting as shown in Patent Document 2 below is used in combination to reinforce the fixing strength of the hanger 4 to the horizontal flange portion 2 of the shape steel 1.

この特許文献２を簡単に説明すると、形鋼の相対峙するフランジ部の他方に引っ掛かる掛止板と、該掛止板に設けられている透孔に一端が挿通すると共に他端が吊り金具内を貫通して該吊り金具後端から突出する螺子棒と、該螺子棒の一端に螺合して前記掛止板を背面から位置固定するナットと、前記吊り金具の後端に当接すると共に前記螺子棒の他端が挿通される固定板と、前記螺子棒の他端に螺合して前記固定板を位置固定するナットとを有した構成とされていて、螺子棒の一端と他端に螺合したナットのいずれか一方又は両方を緊締することで、掛止板がフランジ部の他方に圧接すると共に固定板が吊り金具の後端に圧接し、これにより吊り金具がフランジ部の一方に強固に圧接されて吊り金具の取付固定が補強されることになる構成である。 Briefly explaining this Patent Document 2, one end is inserted through a through hole provided in the other end of the flange portion facing the shape steel, and the other end is in the hanging bracket. A screw rod that protrudes from the rear end of the suspension fitting, a nut that is screwed into one end of the screw rod and fixes the retaining plate from the back, and abuts the rear end of the suspension fitting and A fixing plate through which the other end of the screw rod is inserted; and a nut that is screwed into the other end of the screw rod to fix the position of the fixing plate. By tightening one or both of the nuts that are screwed together, the retaining plate is pressed against the other of the flange, and the fixed plate is pressed against the rear end of the hanging bracket. A structure that is firmly pressed to reinforce the fixing of the suspension bracket A.

例えば、吊り金具４を取付する形鋼１が作業者の目線より高い位置にあって金具本体18の上側で締付ボルト３の締付操作がしにくいような状況では、金具本体18を上下逆向きにして（締付ボルト３のボルト頭部３Ａが金具本体18の下側に突出するようにして）形鋼１のフランジ部２に取付固定するケースも少なくないが、この場合には上記特許文献２のような補強金具を併用することができなくなってしまう。 For example, in a situation where the shape steel 1 to which the hanging bracket 4 is attached is higher than the operator's line of sight and the tightening bolt 3 is difficult to tighten on the upper side of the bracket body 18, the bracket body 18 is turned upside down. There are not a few cases in which it is mounted and fixed to the flange portion 2 of the section steel 1 in such a direction (with the bolt head 3A of the tightening bolt 3 protruding below the metal fitting body 18). It becomes impossible to use the reinforcing metal fitting as in Document 2 together.

即ち、補強金具の螺子棒は、形鋼１の下側（フランジ部２の下側）にしか配することができないから、吊り金具４の挿入配設部19より下方位置に螺子棒を貫通させることになるが、吊り金具４を上下逆向きにしてしまうと、この螺子棒を貫通させるべき位置に締付ボルト３が存在してしまうために、締付ボルト３が邪魔で螺子棒を吊り金具４に貫通させることができず、補強金具の取付が不可能となってしまう。 That is, since the screw rod of the reinforcing metal fitting can be disposed only on the lower side of the structural steel 1 (the lower side of the flange portion 2), the screw rod is passed through the insertion fitting portion 19 of the suspension metal fitting 4 below. However, if the suspension metal fitting 4 is turned upside down, the fastening bolt 3 is present at a position where the screw rod should be penetrated. Therefore, the fastening bolt 3 hinders the screw rod from being hindered. 4 cannot be penetrated, and it is impossible to attach the reinforcing bracket.

本発明は、このような従来の補強金具の問題点を見い出し、これを解決しようとするもので、上下逆向きにして使用した吊り金具とも併用可能な吊り金具取付用補助具を提供することが技術的課題である。 The present invention seeks to solve the problems of the conventional reinforcing metal fittings as described above, and to solve the problems, and to provide an auxiliary tool for attaching the hanging metal fittings that can be used together with the hanging metal fittings used upside down. It is a technical issue.

好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。 An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

例えば、Ｈ形鋼１Ａなどの形鋼１のフランジ部２に締付機構３を介して取付固定された吊り金具４の背側端部４Ａに、金具側固定体５の金具当接部６を当接し、この金具側固定体５の連結部10に棒状連結体９の一端を連結し、この棒状連結体９の他端に形鋼側固定体７を連結し、この形鋼側固定体７の掛止部８を、吊り金具４が取付固定された前記形鋼１のフランジ部２の反対側に位置するフランジ部２若しくは垂直面部に掛止する。 For example, the bracket abutting portion 6 of the bracket-side fixed body 5 is attached to the back end portion 4A of the hanging bracket 4 that is attached and fixed to the flange portion 2 of the section steel 1 such as the H-section steel 1A via the tightening mechanism 3. One end of the rod-like connecting body 9 is connected to the connecting portion 10 of the metal fitting-side fixing body 5, and the shape-steel-side fixing body 7 is connected to the other end of the rod-like connecting body 9. Is hooked to the flange portion 2 or the vertical surface portion located on the opposite side of the flange portion 2 of the structural steel 1 to which the hanging metal fitting 4 is attached and fixed.

すると、吊り金具４は、金具側固定体５（の金具当接部６）によってフランジ部２に押し付けられた状態となり、この吊り金具４がフランジ部２から離れるように外方へ移動しようとしても（吊り金具４の背側端部４Ａが金具当接部６を外方へ押圧しても）、棒状連結体９を介して連結している形鋼側固定体７の掛止部８が形鋼１の反対側のフランジ部２若しくは垂直面部に掛止られていることによって金具側固定体５の外方への移動が阻止されるので、吊り金具４がフランジ部２から離れて脱落することは阻止されて、フランジ部２（形鋼１）への取付固定状態が強固に保持されることになる。 Then, the hanging metal fitting 4 is in a state of being pressed against the flange portion 2 by the metal fitting side fixed body 5 (the metal fitting contact portion 6), and even if the hanging metal fitting 4 tries to move outward so as to be separated from the flange portion 2. (Even if the back end 4A of the hanging bracket 4 presses the bracket abutting portion 6 outward), the hooking portion 8 of the shaped steel side fixed body 7 connected via the rod-shaped connecting body 9 is formed. Since the outward movement of the bracket-side fixing body 5 is prevented by being hooked to the flange portion 2 or the vertical surface portion on the opposite side of the steel 1, the hanging bracket 4 is separated from the flange portion 2 and falls off. Is prevented, and the mounting and fixing state to the flange portion 2 (section steel 1) is firmly held.

また、この際棒状連結体９は、その一端が吊り金具４を貫通せずに金具側固定体５の金具当接部６の側部に突設した連結部10に連結して、吊り金具４の側方に配設することになる。 Further, at this time, the rod-like connecting body 9 is connected to the connecting portion 10 projecting from the side of the metal fitting contact portion 6 of the metal side fixing body 5 without one end penetrating the hanging metal fitting 4. It will be arrange | positioned to the side.

従って、本発明によれば、吊り金具４を上下逆向きとし締付機構３（締付ボルト３）が吊り金具４の下側に突出するようにしてフランジ部２に取付固定した場合でも、締付機構３を邪魔にせずに棒状連結体９を吊り金具４の側方に配して金具側固定体５に連結することができるので、この上下逆向きとした吊り金具４とも何ら支障なく併用して吊り金具４の形鋼１への取付固定状態を補強でき、また、同様にして、もともと締付機構２の締付ボルト３が挿入配設部19の下方に設けられるタイプの吊り金具４とも併用することが可能である。 Therefore, according to the present invention, even when the suspension fitting 4 is turned upside down and the fastening mechanism 3 (clamping bolt 3) is attached to the flange portion 2 so as to protrude below the suspension fitting 4, the fastening member 4 can be tightened. Since the rod-like connecting body 9 can be arranged on the side of the hanging metal fitting 4 and connected to the metal fitting side fixing body 5 without interfering with the attaching mechanism 3, it can be used together with the hanging metal fitting 4 turned upside down without any trouble. Thus, it is possible to reinforce the mounting and fixing state of the hanging bracket 4 to the shape steel 1 and similarly, the hanging bracket 4 of the type in which the fastening bolt 3 of the fastening mechanism 2 is originally provided below the insertion arrangement portion 19. Can be used together.
