ところでこのような吊りボルト用ハンガーは、例えば吊りボルトの締め込みが不十分である場合に地震等で強い揺れを受けると、C形鋼に対して横ずれしたり、係嵌部がC形鋼の開口下端部から外れてC形鋼から脱落したりする不具合が生じるおそれがある。 By the way, such a hanging bolt hanger slips laterally with respect to the C-shaped steel when it is subjected to a strong shaking due to an earthquake or the like when the hanging bolt is not sufficiently tightened, or the engaging part is displaced from the C-shaped steel. There is a risk that it may come off from the lower end of the opening and drop off from the C-shaped steel.

一方、このような不具合を防止するには、吊りボルト用ハンガーを取り囲むような補強部材を別途準備しておき、吊りボルト用ハンガーによってC形鋼に吊りボルトを垂下固定させた後、このハンガーの外側から補強部材を嵌め込んで、ビスなどの締結具によって補強部材をC形鋼に固定する方法が考えられる。しかし、このような吊りボルト用ハンガーの取り付けは、通常、直接目視できない高所での作業となり、補強部材をハンガーに嵌め込む際には時間を要することが想定されるうえ、取り付け作業は腕を上げた状態で行われるため、作業者にかなりの負担を強いることになる。 On the other hand, in order to prevent such a problem, a reinforcing member that surrounds the hanger for the hanging bolt is separately prepared, and after the hanging bolt is suspended and fixed to the C-shaped steel by the hanger for the hanging bolt, the hanger is attached to the hanger. A method of fitting the reinforcing member from the outside and fixing the reinforcing member to the C-shaped steel with fasteners such as screws is conceivable. However, the installation of such hanging bolt hangers usually requires work at a high place where direct visual observation is not possible, and it is assumed that it will take time to fit the reinforcing member into the hanger. Since it is carried out in a raised state, it imposes a considerable burden on the operator.

The suspension bolt 100 shown in FIG. 4 is screwed into the nut portion 23b.

補強部分3は、図1に示すように第二背板部31、及び固定部32で構成される。図3に示すように第二背板部31は、板状をなし上下方向に延在するように設けられる。第二背板部31の幅方向中央部には、上下方向に延在する長孔31aが設けられる。また第二背板部31の下端部には、略水平方向に延在する下片部31bが設けられている。そして固定部32は、第二背板部31の左右において第二背板部31に連結する一対の側壁部32aと、それぞれの側壁部32aの上端部に連結するとともに互いに離反するようにして略水平方向に延在する一対の天板部32bと、天板部32bを貫く円形の孔部32cを備えている。また固定部32は、それぞれの側壁部32aの下端部から略水平方向に延在する一対の側片部32dを備えている。なお側片部32d同士の間には、隙間32eが設けられる。なお、下片部31bと側片部32dの機能については後述する。 The reinforcing portion 3 is composed of a second back plate portion 31 and a fixing portion 32 as shown in FIG. As shown in FIG. 3, the second back plate portion 31 is provided so as to form a plate shape and extend in the vertical direction. A longitudinally extending long hole 31a is provided in the widthwise central portion of the second back plate portion 31 . A lower piece portion 31b extending substantially horizontally is provided at the lower end portion of the second back plate portion 31 . The fixing portion 32 is connected to a pair of side wall portions 32a connected to the second back plate portion 31 on the left and right sides of the second back plate portion 31, and connected to upper end portions of the respective side wall portions 32a and separated from each other. A pair of horizontally extending top plate portions 32b and a circular hole portion 32c passing through the top plate portions 32b are provided. The fixed portion 32 also includes a pair of side piece portions 32d extending substantially horizontally from the lower ends of the side wall portions 32a. A gap 32e is provided between the side pieces 32d. The functions of the lower piece portion 31b and the side piece portion 32d will be described later.

リベット4は、図1に示すように、円柱状の軸部41と、軸部41の一端部に連結するとともに軸部41の外径よりも大径になる円板状のフランジ部42とを備えている。リベット4は、補強部分3に対して本体部分2を、第一背板部21の外側に第二背板部31を位置させるとともに吊りボルト保持部23が一対の側壁部32aの間に収まるようにして挿入しておき、軸部41の他端部を、長孔31aに挿入するとともに下孔21b(図2参照)にも挿入した後、カシメることによって本体部分2に固定される。 The rivet 4, as shown in FIG. I have. The rivets 4 are arranged so that the body portion 2 is positioned with respect to the reinforcing portion 3, the second back plate portion 31 is positioned outside the first back plate portion 21, and the suspension bolt holding portion 23 is accommodated between the pair of side wall portions 32a. After inserting the other end of the shaft portion 41 into the elongated hole 31a and the prepared hole 21b (see FIG. 2), it is fixed to the main body portion 2 by caulking.

ここで、軸部41の外径は、長孔31aの幅よりも小さくなっている。また吊りボルト保持部23の幅は、一対の側壁部32a同士の間隔よりも小さくなっている。このため本体部分2は、補強部分3に対して上下方向に移動することができる。またこのとき、長孔31aは軸部41を上下方向に案内するように機能し、また一対の側壁部32aは吊りボルト保持部23を上下方向に案内するように機能する。なおフランジ部42の外径は、長孔31aの幅よりも大きいため、補強部分3が本体部分2から外れることはない。 Here, the outer diameter of the shaft portion 41 is smaller than the width of the long hole 31a. The width of the suspension bolt holding portion 23 is smaller than the interval between the pair of side wall portions 32a. Therefore, the body portion 2 can move vertically with respect to the reinforcing portion 3 . At this time, the elongated hole 31a functions to guide the shaft portion 41 in the vertical direction, and the pair of side wall portions 32a functions to guide the suspension bolt holding portion 23 in the vertical direction. Since the outer diameter of the flange portion 42 is larger than the width of the elongated hole 31a, the reinforcing portion 3 does not come off from the main body portion 2. As shown in FIG.

このような構成になる吊りボルト固定具1に対し、図4に示すように吊りボルト100は、隙間32eを通してナット部23bに螺合される。なお吊りボルト100は、完全には締め込まず、吊りボルト100の上端部と上片部22bとの間には、十分な隙間をあけておく。そしてこの状態の吊りボルト固定具1を、C形鋼200に取り付ける。なおC形鋼200は、リップ溝形鋼とも称されるものであって、図示したように横断面形状がC字状をなす薄板状のものである。また本実施形態のC形鋼200は、開口部201を側方に指向させた状態で天井下地に使用されるものとする。そして、開口部201の下方に位置するとともに上方に向けて指向する部位を開口下端部202と称し、開口下端部202から略水平方向に延在する部位を下面部203と称することとする。 As shown in FIG. 4, the suspension bolt 100 is screwed into the nut portion 23b through the gap 32e in the suspension bolt fixture 1 having such a configuration. The hanging bolt 100 is not completely tightened, and a sufficient gap is left between the upper end portion of the hanging bolt 100 and the upper piece portion 22b. Then, the hanging bolt fixture 1 in this state is attached to the C-shaped steel 200 . The C-shaped steel 200 is also called lip channel steel, and is a thin plate having a C-shaped cross section as shown in the figure. Moreover, the C-shaped steel 200 of this embodiment shall be used for a ceiling base|substrate in the state which directed the opening part 201 to the side. A portion located below the opening 201 and directed upward is referred to as an opening lower end portion 202 , and a portion extending substantially horizontally from the opening lower end portion 202 is referred to as a lower surface portion 203 .

吊りボルト固定具1をC形鋼200に取り付けるにあたっては、まず上部係合部22を開口下端部202に引っ掛けておき、更に吊りボルト100の上端部が下面部203に近づく向きに吊りボルト100を回転させる。これにより下面部203は、吊りボルト100によって締め込まれて上片部22bと吊りボルト100の上端部で挟持されるため、吊りボルト100は、C形鋼200に垂下固定される。 When attaching the hanging bolt fixture 1 to the C-shaped steel 200, first, the upper engaging portion 22 is hooked on the opening lower end portion 202, and then the hanging bolt 100 is moved so that the upper end portion of the hanging bolt 100 approaches the lower surface portion 203. rotate. As a result, the lower surface portion 203 is tightened by the hanging bolt 100 and sandwiched between the upper piece portion 22b and the upper end portion of the hanging bolt 100, so that the hanging bolt 100 is suspended and fixed to the C-shaped steel 200.

その後は、図5に示すように本体部分2に対して補強部分3を上方へ移動させて、天板部32bを下面部203に当て付ける。上述したように補強部分3は、リベット4によって本体部分2から外れることがないうえ、上方へ移動させる際は、長孔31aと軸部41、及び一対の側壁部32aと吊りボルト保持部23によって案内されるため、直接目視できず、また腕を上げた状態で行われる高所での作業も簡単に行うことができる。 After that, as shown in FIG. 5 , the reinforcing portion 3 is moved upward with respect to the main body portion 2 and the top plate portion 32 b is brought into contact with the lower surface portion 203 . As described above, the reinforcing portion 3 is not detached from the main body portion 2 by the rivets 4, and when it is moved upward, it is secured by the long hole 31a and the shaft portion 41, and the pair of side wall portions 32a and the suspension bolt holding portion 23. Since the operator is guided, direct visual observation is not possible, and work at high places, which is performed with arms raised, can be easily performed.

その後はビスなどの締結具300を、孔部32cを挿通させて下面部203に締め付けることによって、補強部分3をC形鋼200に取り付けることができる。このとき本体部分2は、C形鋼200に固定された補強部分3によって取り囲まれた状態になっているため、本体部分2がC形鋼200に対して横ずれしたり脱落したりする不具合を防止することができる。なお、吊りボルト100に下方へ向かう過大な力が作用した際は、吊りボルト100に作用する力によって吊りボルト保持部23が下方へ撓むように変形し、更には本体部分2が脱落するおそれがあるが、吊りボルト保持部23の下方に位置する下片部31bと側片部32dによって吊りボルト保持部23の過剰な変形が抑制できるため、本体部分2の脱落をより確実に防止することができる。また、本体部分2に対して補強部分3を移動させることができることから、サイズや板厚が多少異なるC形鋼200に対しても、同一の吊りボルト固定具1を使用することができる。 After that, the reinforcing portion 3 can be attached to the C-shaped steel 200 by inserting a fastener 300 such as a screw through the hole portion 32c and tightening it to the lower surface portion 203 . At this time, since the main body portion 2 is surrounded by the reinforcing portion 3 fixed to the C-shaped steel 200, it prevents the main body portion 2 from laterally slipping or falling off from the C-shaped steel 200. can do. When an excessive downward force acts on the suspension bolt 100, the force acting on the suspension bolt 100 deforms the suspension bolt holding portion 23 so as to bend downward, and the main body portion 2 may drop off. However, excessive deformation of the suspension bolt holding portion 23 can be suppressed by the lower piece portion 31b and the side piece portion 32d located below the suspension bolt holding portion 23, so that the main body portion 2 can be more reliably prevented from falling off. . Further, since the reinforcing portion 3 can be moved with respect to the main body portion 2, the same suspension bolt fixture 1 can be used for C-shaped steels 200 having slightly different sizes and plate thicknesses.

以上、本発明について具体的な実施形態を示しながら説明したが、本発明に従う吊りボルト固定具は上述した実施形態に限られるものではなく、特許請求の範囲に従う範疇で種々の変更を加えたものも含まれる。例えば上述した実施形態では、補強部分3の第二背板部31に長孔31aを設け、リベット4の軸部41は第一背板部21を有する本体部分2に固定されるように構成したが、本体部分2の第一背板部21に長孔を設け、軸部41を持つリベット4は補強部分3に固定されるように構成してもよい。またフランジ部42は、長孔31aよりも外形が大きければよく、形状は円形でなくてもよい。なお本体部分2に設けた上孔21aは、ビスなどの締結具を挿通させて図4に示した開口下端部202に締め付けることによって、本体部分2をC形鋼200に固定することを意図して設けているが、必ずしも設ける必要はない。 As described above, the present invention has been described by showing specific embodiments, but the hanging bolt fixture according to the present invention is not limited to the above-described embodiments, and may be modified in various ways within the scope of the claims. is also included.
