Description
本発明は、天井下地の施工に際して使用される振れ止め用下地材の固定金具に関し、詳しくは、躯体天井部から所定の間隔を存して垂下される複数の吊りボルトと、複数の吊りボルト間に架設される断面コ字状の振れ止め用下地材とを含む天井下地の施工に際して、振れ止め用下地材を吊りボルトに固定するために使用される固定金具に関する。 TECHNICAL FIELD The present invention relates to a fixture for fixing a base material for steadying that is used in the construction of a ceiling base, and in particular, between a plurality of suspension bolts suspended at a predetermined interval from a housing ceiling and a plurality of suspension bolts. The present invention relates to a fixing bracket used for fixing a base material for steadying to a suspension bolt in the construction of a ceiling base including a base material for steadying that has a U-shaped cross section.
従来の天井構造としては、在来天井やシステム天井が知られている（例えば、特許文献１参照）。在来天井は、吊りボルトを介して躯体天井部に支持される複数の野縁受け（チャンネル）と、ジョイント部材（Ｗクリップ、Ｓクリップ等）を介して野縁受けに支持される複数の野縁（Ｗバー、Ｓバー等）と、野縁にビス止めされる天井パネルとから構成される。また、システム天井は、吊りボルトを介して躯体天井部に支持される複数の野縁受けと、ジョイント部材（Ｔバーハンガー等）を介して野縁受けに支持される複数のＴバーと、格子状に組まれたＴバー上に載置される天井パネルとから構成される。 As a conventional ceiling structure, a conventional ceiling or a system ceiling is known (for example, see Patent Document 1). The conventional ceiling has a plurality of field receivers (channels) supported by the frame ceiling through suspension bolts, and a plurality of fields supported by the field receivers through joint members (W clips, S clips, etc.). It is composed of an edge (W bar, S bar, etc.) and a ceiling panel screwed to the field edge. Further, the system ceiling includes a plurality of field receivers supported by the frame ceiling part via suspension bolts, a plurality of T bars supported by the field receivers via joint members (such as T-bar hangers), and a lattice. It is comprised from the ceiling panel mounted on the T-bar assembled in the shape.
ところで、このような天井構造では、吊りボルトの間隔を維持するために、複数の吊りボルト間に振れ止め用下地材を架設することが好ましい。特に、長尺な吊りボルトを用いる天井下地においては、吊りボルトの振れ幅が大きいため、振れ止め用下地材による吊りボルトの振れ止めが必須となっている。そして、振れ止め用下地材としては、特許文献１に示されるように、複数の吊りボルト間に水平状に架設される梁タイプのものや、特許文献２に示されるように、複数の吊りボルト間に傾斜状に架設される筋交いタイプのものが知られている。 By the way, in such a ceiling structure, in order to maintain the space | interval of a suspension bolt, it is preferable to construct the base material for steadying between several suspension bolts. In particular, in a ceiling base using a long suspension bolt, since the swing width of the suspension bolt is large, it is essential to prevent the suspension bolt from swinging with a base material for steadying. And as a base material for steadying, as shown in patent document 1, the thing of the beam type laid horizontally between several suspension bolts, or as shown in patent document 2, a plurality of suspension bolts A bracing type that is installed in a slanting manner in between is known.
振れ止め用下地材を含む天井下地の施工に際しては、振れ止め用下地材を吊りボルトに固定するための固定金具が使用される。この固定金具は、振れ止め用下地材に固定される振れ止め用下地材固定部と、吊りボルトに固定される吊りボルト固定部とを備えるものであるが、従来の固定金具は、振れ止め用下地材固定部と吊りボルト固定部が別部材で構成されているため、一箇所の固定に必要な部品点数が多くなり、コスト高となっている。しかも、一箇所の固定に数多くの緊締金具（ボルト、ナット、ビス等）を使用するため、一箇所を固定するだけでも相当の時間を必要とし、施工効率に劣るという問題がある。また、特許文献２に示される固定金具は、振れ止め用下地材が長ボルト材であることが前提であり、振れ止め用下地材を断面コ字状のチャンネル材とした場合には、適用が困難であった。 In the construction of the ceiling foundation including the steady rest base material, a fixing bracket for fixing the steady rest base material to the suspension bolt is used. This fixing bracket is provided with a steady-state base material fixing portion fixed to a steady-state base material and a suspension bolt fixing portion fixed to a suspension bolt. Since the base material fixing part and the suspension bolt fixing part are made of different members, the number of parts required for fixing at one place increases, resulting in high costs. In addition, since a large number of fasteners (bolts, nuts, screws, etc.) are used for fixing one place, it takes a considerable amount of time to fix only one place, resulting in poor construction efficiency. In addition, the fixing bracket shown in Patent Document 2 is based on the premise that the steadying base material is a long bolt material, and is applicable when the steadying base material is a channel material having a U-shaped cross section. It was difficult.
そこで、図６に示すように、振れ止め用下地材に固定される振れ止め用下地材固定部と、吊りボルトに固定される吊りボルト固定部とを一体に備える固定金具が提案されている。この固定金具１００は、側面視コ字状に形成されており、上面部及び下面部の先端に切り欠き溝１０１からなる吊りボルト固定部を有している。この固定金具１００を用いて、振れ止め用下地材３を吊りボルト２に固定する場合は、振れ止め用下地材３に固定金具１００を外嵌させると共に、固定金具１００に形成される上下の切り欠き溝１０１に吊りボルト２を挿入させる。ここで、固定金具１００の側面部に形成されるネジ孔１０２にネジ１０３をねじ込むと、振れ止め用下地材３と吊りボルト２とが互に引き寄せられて固定される。このようにすると、振れ止め用下地材３に固定される振れ止め用下地材固定部と、吊りボルト２に固定される吊りボルト固定部とを備えるものでありながら、振れ止め用下地材固定部と吊りボルト固定部の一体化により、部品点数の削減及びコストダウンが可能になるだけでなく、チャンネル材からなる振れ止め用下地材３の固定に好適に用いることができる。 Therefore, as shown in FIG. 6, there has been proposed a fixing bracket integrally including a steadying base material fixing part fixed to the steadying base material and a suspension bolt fixing part fixed to the suspension bolt. The fixing metal fitting 100 is formed in a U-shape when viewed from the side, and has a suspension bolt fixing portion including a notch groove 101 at the tip of the upper surface portion and the lower surface portion. When the steadying base material 3 is fixed to the suspension bolt 2 by using the fixing bracket 100, the fixing bracket 100 is externally fitted to the steadying base material 3, and the upper and lower cuts formed in the fixing bracket 100 are also fitted. The suspension bolt 2 is inserted into the notch groove 101. Here, when the screw 103 is screwed into the screw hole 102 formed in the side surface portion of the fixing bracket 100, the steadying base material 3 and the suspension bolt 2 are attracted and fixed to each other. In this case, the steadying base material fixing part is provided with the steadying base material fixing part fixed to the steadying base material 3 and the suspension bolt fixing part fixed to the suspension bolt 2. By integrating the suspension bolt fixing portion with the suspension bolt, not only can the number of parts be reduced and the cost can be reduced, but also it can be suitably used for fixing the steady rest base material 3 made of channel material.
しかしながら、図６に示す固定金具１００を用いて天井下地を施工する場合、施工者は、ネジ１０３のねじ込みが完了するまでの間、振れ止め用下地材３を所定の高さで支えている必要があるため、施工性に劣るという問題がある。また、吊りボルト２に対する振れ止め用下地材３の固定強度がすべてネジ１０３のねじ込み力に依存しているため、ネジ１０３が緩むと、吊りボルト２に対して振れ止め用下地材３が位置ズレし、天井下地の強度が低下する可能性がある。
本発明は、上記の如き問題点を一掃すべく創案されたものであって、振れ止め用下地材固定部と吊りボルト固定部の一体化により、部品点数の削減及びコストダウンが可能になるだけでなく、チャンネル材からなる振れ止め用下地材の固定に好適に用いることができるものでありながら、ビス固定前に振れ止め用下地材を吊りボルトに仮固定することを可能にして、天井下地の施工性を向上させることができるだけでなく、吊りボルトに対する振れ止め用下地材の固定強度を長期に亘って維持することができる振れ止め用下地材の固定金具を提供することを目的としている。 The present invention was devised to eliminate the above-mentioned problems, and the number of parts can be reduced and the cost can be reduced by integrating the base material fixing part for steadying and the suspension bolt fixing part. In addition to being able to be used suitably for fixing the base material for steadying made of channel material, it is possible to temporarily fix the base material for steadying to the suspension bolt before screw fixing, An object of the present invention is to provide a fixing member for a steadying base material that can not only improve the workability of the steadying material but also can maintain the fixing strength of the steadying base material to the suspension bolt over a long period of time.
上記課題を解決するために本発明に係る振れ止め用下地材の固定金具は、躯体天井部から所定の間隔を存して垂下される複数の吊りボルトと、複数の吊りボルト間に架設される断面コ字状の振れ止め用下地材とを含む天井下地の施工に際して、振れ止め用下地材を吊りボルトに固定するために使用される固定金具であって、該固定金具は、振れ止め用下地材に固定される振れ止め用下地材固定部と、吊りボルトに固定される吊りボルト固定部とを一体に備え、前記振れ止め用下地材固定部は、前記吊りボルト固定部の両側に、振れ止め用下地材に外嵌可能な側面視コ字状に形成される側面部、上面部、下面部を有するとともに、上面部の先端には、外嵌した振れ止め用下地材を抜け止めするよう下方に折曲形成された折り返し片を有し、前記吊りボルト固定部は、振れ止め用下地材固定部の側面部中央に、その内周部が吊りボルトに外嵌するよう平面視Ｕ字状に形成されてとともに、前記内周部には、吊りボルトのネジ山に係合する係合爪を形成せしめ、前記吊りボルト固定部の内周部を吊りボルトに外嵌させ、かつ、前記係合爪を吊りボルトのネジ山に係合させて位置決めした状態で、振れ止め用下地材固定部を振れ止め用下地材に対して、その上面部先端に前記折り返し片を係合させて外嵌させたとき、前記吊りボルト固定部の内周部と振れ止め用下地材の側面部との間で吊りボルトを挟持せしめて、前記係合爪と吊りボルトのネジ山との係合ズレや外れを防止するとともに、この挟持状態を、前記振れ止め用下地材に外嵌係合せしめた折り返し片で維持せしめて、前記両固定部で振れ止め用下地材の抜け止めと取付位置ズレを防止することにより、振れ止め用下地材を吊りボルトに対して仮固定可能とし、さらに、仮固定状態の振れ止め用下地材を振れ止め用下地材固定部にビス固定するよう構成されていることを特徴とするものである。 In order to solve the above-mentioned problems, a fixing bracket for a steady rest base material according to the present invention is installed between a plurality of suspension bolts suspended at a predetermined distance from a housing ceiling and a plurality of suspension bolts. A fixing bracket used for fixing the steady rest base material to the suspension bolt in the construction of a ceiling foundation including a U-shaped steady rest base material, the securing bracket being a steady rest base A base material fixing portion for steadying that is fixed to the material and a suspension bolt fixing portion that is fixed to the suspension bolt are integrally provided, and the base material fixing portion for steadying is shaken on both sides of the suspension bolt fixing portion. side portion formed in the outer fitting possible side view C-shape the stop for the base material, the top surface portion, and having a lower surface portion, the distal end of the upper surface portion, to retaining the anti-vibration base material which is fitted has a folded piece formed by bending downwardly, the Ri bolt fixing portion, the side portion center of the anti-vibration base sheet fixing part, together with the formed in plan view U-shape so as to fitted to the inner peripheral portion hanger bolts, to the inner peripheral portion, hanging because Shi of forming the engaging claws engage the bolt threads, fitted to the inner peripheral portion of the hanger rod of the hanger bolt fixing part, and to engage the threads of hanging the engaging pawl bolt while positioning Te, shake for the stop for the base material fixing portion stopper for the base material shake, when brought into fitted by engaging the folded piece on its upper surface front end, of the hanger rod fixing portion and allowed clamping the hanger rod between the side surface portion of the stopper for the base material shake the peripheral portion, thereby preventing the engagement deviation and out of the threads of the engagement claw and hanging bolts, the clamping state, the and allowed to maintain in the folded piece was allowed fitted engaging the stop for the base material deflection, the two fixed By preventing stopper and the mounting position deviation of the anti-vibration base material in, run-out and can temporarily fixed relative to the hanger rod a stop for the base material, further, for preventing shake-preventing ground material deflection temporary fixing state and it is characterized in that it is configured to screw fixing the base member fixing portion.

以下、本発明の実施の形態を好適な実施の形態として例示する振れ止め用下地材の固定金具を図面に基づいて詳細に説明する。図１は、本発明の実施形態に係る天井下地の概略側面図である。この図に示す天井下地には、躯体天井部１から所定の間隔を存して垂下される複数の吊りボルト（長ボルト材）２と、複数の吊りボルト２間に架設される振れ止め用下地材（チャンネル材）３と、ハンガー４を介して吊りボルト２の下端部に支持される野縁受け（チャンネル材）５とが含まれている。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A steadying base material fixing bracket exemplified by a preferred embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic side view of a ceiling foundation according to an embodiment of the present invention. The ceiling foundation shown in this figure includes a plurality of suspension bolts (long bolt members) 2 suspended from the housing ceiling 1 at a predetermined interval, and a steady rest foundation constructed between the plurality of suspension bolts 2. A material (channel material) 3 and a field edge receiver (channel material) 5 supported by a lower end portion of the suspension bolt 2 via a hanger 4 are included.
本実施形態の振れ止め用下地材３は、断面コ字状のチャンネル材からなり、複数の吊りボルト２間に水平状に架設される梁タイプとなっている。そして、本発明の実施形態に係る固定金具６を用いて、振れ止め用下地材３が吊りボルト２に固定されるようになっている。 The steady rest base material 3 of the present embodiment is made of a channel material having a U-shaped cross section, and is a beam type that is laid horizontally between a plurality of suspension bolts 2. And the base material 3 for steadying is fixed to the suspension bolt 2 using the fixture 6 which concerns on embodiment of this invention.
図２の（Ａ）、（Ｂ）、（Ｃ）、（Ｄ）は、本発明の実施形態に係る固定金具の正面図、平面図、側面図、Ａ部拡大断面図である。これらの図に示すように、固定金具６は、振れ止め用下地材３に固定される振れ止め用下地材固定部６ａと、吊りボルト２に固定される吊りボルト固定部６ｂとを備えている。本発明の固定金具６では、振れ止め用下地材固定部６ａと吊りボルト固定部６ｂを別部材とせず、一体化させている。例えば、本実施形態の固定金具６は、予め所定の形状に形成された一枚の金属板を側面視コ字状に曲げ加工して振れ止め用下地材固定部６ａとするとともに、振れ止め用下地材固定部６ａの側面部に吊りボルト固定部６ｂを形成している。 2A, 2B, 2C, and 2D are a front view, a plan view, a side view, and an enlarged A sectional view of a fixing bracket according to an embodiment of the present invention. As shown in these drawings, the fixing bracket 6 includes a steadying base material fixing part 6 a that is fixed to the steadying base material 3 and a suspension bolt fixing part 6 b that is fixed to the suspension bolt 2. . In the fixing bracket 6 of the present invention, the steadying base material fixing portion 6a and the suspension bolt fixing portion 6b are integrated without being separated from each other. For example, the fixing bracket 6 of the present embodiment is obtained by bending a single metal plate formed in a predetermined shape into a U-shape as viewed from the side to form a steady-state base material fixing portion 6a. A suspension bolt fixing portion 6b is formed on a side surface portion of the base material fixing portion 6a.
振れ止め用下地材固定部６ａは、振れ止め用下地材３に外嵌可能な側面視コ字状に形成されるとともに、上面部の先端には、外嵌した振れ止め用下地材３を抜け止めする折り返し片６ｃが形成され、下面部６ａ’は、振れ止め用下地材３の厚さ幅よりも長く、かつ、テーパ状に僅かに内側に傾斜し先端部を外側に広げて折曲形成されている。この下面部６ａ’は、振れ止め用下地材３に鋼製のチャンネル材が用いられた際に、その製作誤差（一般的に±０．５ｍｍ程度）を吸収できるようにしたもので、振れ止め用下地材３に弾圧されるものである。なお、振れ止め用下地材３が製作誤差を考慮する必要のない押し出し成形によるアルミ製の場合には、下面部６ａ’を上面部と同様直角に折曲して、その長さも短くして形成しても良い。また、振れ止め用下地材固定部６ａの側面部には、二つのビス孔６ｄが形成されている。このビス孔６ｄを介して振れ止め用下地材３にビス７を螺込むことにより、振れ止め用下地材固定部６ａと振れ止め用下地材３とが固定されるようになっている。 The steady-state base material fixing portion 6a is formed in a U-shape in a side view that can be externally fitted to the steady-state base material 3, and the top-end tip of the steady-state base material 3 is removed. A folded piece 6c to be stopped is formed, and the lower surface portion 6a ′ is longer than the thickness width of the steady rest base material 3 and is slightly bent inwardly in a taper shape so that the tip end portion is expanded outward and bent. Has been. The lower surface portion 6a 'is designed to absorb a manufacturing error (generally about ± 0.5 mm) when a steel channel material is used as the steady rest base material 3. It is pressed against the base material 3 for use. In the case where the steady rest base material 3 is made of aluminum that does not need to consider manufacturing errors, it is formed by bending the lower surface portion 6a 'at a right angle like the upper surface portion and shortening the length. You may do it. Further, two screw holes 6d are formed in the side surface portion of the steady rest base material fixing portion 6a. By screwing the screw 7 into the steady rest base material 3 through the screw hole 6d, the steady rest base material fixing portion 6a and the steady rest base material 3 are fixed.
吊りボルト固定部６ｂは、振れ止め用下地材固定部６ａの側面部に平面視Ｕ字状に形成されており、吊りボルト２に外嵌可能となっている。また、平面視Ｕ字状に形成された吊りボルト固定部６ｂの内周部には、吊りボルト２のネジ山に係合する係合爪６ｅが形成されている。図２の（Ｄ）に示すように、本実施形態の係合爪６ｅは、ネジ山２ピッチ分に対応する側面形状を有しており、吊りボルト固定部６ｂの上下２箇所に切り起し状に形成されるものである。 The suspension bolt fixing portion 6 b is formed in a U shape in a plan view on the side surface portion of the steadying base material fixing portion 6 a and can be fitted onto the suspension bolt 2. Further, an engaging claw 6e that engages with the thread of the suspension bolt 2 is formed on the inner peripheral portion of the suspension bolt fixing portion 6b formed in a U shape in plan view. As shown in FIG. 2D, the engaging claw 6e of the present embodiment has a side surface shape corresponding to two pitches of the thread and cuts and raises at two places on the upper and lower sides of the suspension bolt fixing portion 6b. It is formed in a shape.
次に、本実施形態に係る固定金具６の使用例について説明する。図３は、本発明の実施形態に係る固定金具の使用例（仮固定状態）を示す斜視図、図４は、本発明の実施形態に係る固定金具の使用例（仮固定状態）を示す断面図、図５は、本発明の実施形態に係る固定金具の使用例（固定状態）を示す斜視図である。本実施形態の固定金具６を用いて、振れ止め用下地材３を吊りボルト２に固定する場合は、まず、固定金具６の吊りボルト固定部６ｂを一側方から吊りボルト２に外嵌させる。このとき、吊りボルト固定部６ｂの内周部に形成される係合爪６ｅを吊りボルト２のネジ山に係合させて、吊りボルト２に対する固定金具６の上下位置を決める。次に、固定金具６の振れ止め用下地材固定部６ａを振れ止め用下地材３に外嵌させる。このとき、振れ止め用下地材固定部６ａの折り返し片６ｃを振れ止め用下地材３の上面部先端に係合させて、下面部６ａ’の弾発に抗して叩き込むと下面部６ａ’が振れ止め用下地材３の下面に弾圧係合した状態で振れ止め用下地材３を抜け止めする。 Next, a usage example of the fixing bracket 6 according to the present embodiment will be described. FIG. 3 is a perspective view showing a usage example (temporary fixing state) of the fixing bracket according to the embodiment of the present invention, and FIG. 4 is a cross-sectional view showing a usage example (temporary fixing state) of the fixing bracket according to the embodiment of the present invention. FIG. 5 is a perspective view showing an example of use (fixed state) of the fixture according to the embodiment of the present invention. When fixing the steady rest base material 3 to the suspension bolt 2 using the fixing bracket 6 of the present embodiment, first, the suspension bolt fixing portion 6b of the fixing bracket 6 is externally fitted to the suspension bolt 2 from one side. . At this time, the engaging claw 6e formed on the inner peripheral portion of the suspension bolt fixing portion 6b is engaged with the thread of the suspension bolt 2, and the vertical position of the fixing bracket 6 with respect to the suspension bolt 2 is determined. Next, the steadying base material fixing portion 6 a of the fixture 6 is externally fitted to the steadying base material 3. At this time, when the folded piece 6c of the steady-state base material fixing portion 6a is engaged with the top end of the top surface portion of the steady-state base material 3 and is struck against the impact of the bottom surface portion 6a ′, the bottom surface portion 6a ′ is formed. The steady rest base material 3 is prevented from coming off while being elastically engaged with the lower surface of the steady rest base material 3.
このようにすると、吊りボルト固定部６ｂと振れ止め用下地材３の側面部との間で吊りボルト２が挟持されるので、吊りボルト固定部６ｂの係合爪６ｅと吊りボルト２のネジ山との係合がズレたり外れたりしなくなり、しかも、この挟持状態が折り返し片６ｃと下面部６ａ’とで取付位置ズレを防止した状態で振れ止め用下地材３の抜け止めが維持される。これにより、振れ止め用下地材３を吊りボルト２に対して仮固定することが可能になる。そして、全ての個所において仮組付け固定が完了したら、最終的な位置決め調整をしながら振れ止め用下地材固定部６ａに形成されるビス孔６ｄを介して、振れ止め用下地材３にビス７を螺込むことにより、振れ止め用下地材３とが本固定されることになる。 If it does in this way, since the suspension bolt 2 is clamped between the suspension bolt fixing | fixed part 6b and the side part of the base material 3 for steadying, the engaging claw 6e of the suspension bolt fixing | fixed part 6b and the thread of the suspension bolt 2 In addition, the base material 3 for steadying is kept from slipping out in a state in which the attachment position is prevented from being displaced between the folded piece 6c and the lower surface portion 6a ′. This makes it possible to temporarily fix the steady rest base material 3 to the suspension bolt 2. Then, when the temporary assembly and fixing are completed at all locations, the screw 7 is attached to the steady rest base material 3 through the screw holes 6d formed in the steady rest base material fixing portion 6a while performing final positioning adjustment. Is fixed to the steady rest base material 3.

In the construction of the ceiling foundation including the steady rest base material 3, the securing bracket 6 is used for fixing the steady rest base material 3 to the suspension bolt 2. Since the base material fixing portion 6a for the steady rest fixed to the base material 3 for the steady rest and the suspension bolt fixing portion 6b fixed to the suspension bolt 2 are integrally provided, the base material fixing portion 6a for the steady rest is provided. Compared with the case where the suspension bolt fixing part 6b is formed of a separate member, the number of parts can be reduced and the cost can be reduced.
また、振れ止め用下地材固定部６ａは、吊りボルト固定部６ｂの両側に、振れ止め用下地材３に外嵌可能な側面視コ字状に形成される側面部、上面部、下面部を有するとともに、上面部の先端には、外嵌した振れ止め用下地材３を抜け止めするよう下方に折曲形成された折り返し片６ｃを有し、吊りボルト固定部６ｂは、振れ止め用下地材固定部６ａの側面部中央に、その内周部が吊りボルト２に外嵌するよう平面視Ｕ字状に形成するとともに、内周部には、吊りボルト２のネジ山に係合する係合爪６ｅを形成せしめているので、吊りボルト固定部６ｂの内周部を吊りボルト２に外嵌さ、かつ、係合爪６ｅを吊りボルト２のネジ山に係合させて位置決めしせた状態で、振れ止め用下地材固定部６ａを振れ止め用下地材３に対して、その上面部先端に折り返し片６ｃを係合させて外嵌させたとき、吊りボルト固定部６ｂの内周部と振れ止め用下地材３の側面部との間で吊りボルト２を挟持して、係合爪６ｅと吊りボルト２のネジ山との係合ズレや外れを防止すると共に、この挟持状態を、振れ止め用下地材３に外嵌係合せしめた折り返し片６ｃで維持せしめて、両固定部６ａ、６ｂによる振れ止め用下地材３の抜け止めと取付位置ズレを防止することにより、振れ止め用下地材３を吊りボルト２に対して仮固定することが可能となる。
従って、チャンネル材からなる振れ止め用下地材３の固定に好適に用いることができる固定金具６でありながら、振れ止め用下地材固定部６ａの折り返し片６ｃを振れ止め用下地材３の上面部先端に係合させた状態から、その側面部、上面部、下面部６ａ’を外嵌させ、かつ、吊りボルト固定部６ｂの内周部を吊りボルト２に外嵌させて組付けることができるので、吊りボルト固定部６ｂの係合爪６ｅを含む内周部が、吊りボルト２の外周にぴったりとかぶせ合わされた状態で、振れ止め用下地材３の側面部との間で吊りボルト２を挟持することができ、かつ、この挟持状態を外嵌係合する折り返し片６ｃによって維持することができる。その結果、係合爪６ｅと吊りボルト２のネジ山との係合ズレや外れ防止ができるだけでなく、取付位置ズレを防止した状態で振れ止め用下地材３の抜け止めを維持することができ、ビス固定前に振れ止め用下地材３を吊りボルト２に仮固定することを可能ならしめ、施工者は、ビス７のねじ込みが完了するまでの間、振れ止め用下地材３を所定の高さで支えている必要がなくなると共に、この仮固定が完了した後であっても、最終的な位置決め調整をしながら本固定することができるので、施工性を大幅に改善することができるだけでなく、吊りボルト２に対する振れ止め用下地材３の固定強度を長期に亘って維持することができる。
このとき、振れ止め用下地材固定部６ａの折り返し片６ｃを振れ止め用下地材３の上面部先端に係合させて、下面部６ａ’の弾発に抗して叩き込むと下面部６ａ’が振れ止め用下地材３の下面に弾圧係合した状態で振れ止め用下地材３を抜け止めする。
Further, the steady-state base material fixing portion 6a has a side surface portion, an upper surface portion, and a bottom surface portion that are formed in a U-shape in a side view that can be fitted on the steady-state base material 3 on both sides of the suspension bolt fixing portion 6b. And has a folded piece 6c bent downward so as to prevent the externally attached steady-preventing base material 3 from slipping off, and the suspension bolt fixing part 6b is provided with a steady-state base material. In the center of the side surface portion of the fixed portion 6a , the inner peripheral portion is formed in a U shape so as to be fitted on the suspension bolt 2, and the inner peripheral portion is engaged with the thread of the suspension bolt 2 since because Shi not form claw 6e, the inner peripheral portion of the hanger bolts 2 fitted of hanging bolt fixing part 6b, and causes and positioned to engage the threads of the hanging engagement claw 6e bolt 2 in state, against the stop for the base material 3 shake-preventing ground material fixed portions 6a shake, the upper surface portion When by engaging the folded piece 6c was fitted to the end, by holding the hanging bolts 2 between the inner peripheral portion and the deflection side of the stop for the base sheet 3 of the hanging bolt fixing part 6b, the engaging claw 6e and the thread of the suspension bolt 2 are prevented from being displaced or disengaged , and this clamping state is maintained by the folded piece 6c that is fitted and engaged with the base material 3 for steadying, so that both fixing portions 6a , 6b prevents the steady-state base material 3 from slipping out and prevents the mounting position from being displaced, so that the steady-state base material 3 can be temporarily fixed to the suspension bolt 2.
Therefore, the folded piece 6c of the steadying base material fixing portion 6a is fixed to the top surface portion of the steadying base material 3 while being the fixing bracket 6 that can be suitably used for fixing the steadying base material 3 made of a channel material. From the state of being engaged with the tip, the side surface portion, the upper surface portion, and the lower surface portion 6a ′ can be externally fitted, and the inner peripheral portion of the suspension bolt fixing portion 6b can be externally fitted to the suspension bolt 2 for assembly. Therefore, in the state where the inner peripheral portion including the engaging claw 6e of the suspension bolt fixing portion 6b is exactly covered with the outer periphery of the suspension bolt 2, the suspension bolt 2 is connected to the side surface portion of the steady rest base material 3. The clamped state can be maintained, and the clamped state can be maintained by the folded piece 6c that is externally engaged. As a result, it is possible not only to prevent the engagement claw 6e and the thread of the suspension bolt 2 from engaging and disengagement, but also to prevent the steady-state base material 3 from coming off while preventing the mounting position deviation. Then, it is possible to temporarily fix the steady rest base material 3 to the suspension bolt 2 before fixing the screw, and the installer keeps the steady rest base material 3 to a predetermined height until the screw 7 is screwed in. Rutotomoni that it is not necessary that supports in is, even after the temporary fixing is completed, final positioning adjustments were able to present fixing while Runode, be significantly improved workability Not only can the fixing strength of the steady rest base material 3 with respect to the suspension bolt 2 be maintained for a long period of time .
At this time, when the folded piece 6c of the steady-state base material fixing portion 6a is engaged with the top end of the top surface portion of the steady-state base material 3 and is struck against the impact of the bottom surface portion 6a ′, the bottom surface portion 6a ′ is formed. The steady rest base material 3 is prevented from coming off while being elastically engaged with the lower surface of the steady rest base material 3.
また、振れ止め用下地材固定部６ａは、その下面部６ａ’を、振れ止め用下地材３に対して弾発に抗して叩き込み係合可能とすべく上面部側（内側）に向けて傾斜せしめて形成し、該下面部６ａ’が、外嵌した振れ止め用下地材３の下面に弾圧係合した状態で、前記折り返し片６ｃと吊りボルト固定部６ｂによる仮固定状態を、更に抜け止め保持せしめる構成となっている。このため、製作誤差によって、振れ止め用下地材３の一部の個所や略全長に渡って、吊りボルト２のネジ山と係合爪６ｅとの係合が緩んだり、外れたりして折り返し片６ｃと吊りボルト固定部６ｂだけでは確実な挟持状態を維持することができない場合であっても、折り返し片６ｃの係合と下面部６ａ’の弾圧力による係合で、振れ止め用下地材３をしっかりと挟持状態を保持して、不用意に位置ズレを生じることなく仮組付け固定することができる。 Further, the steady-state base material fixing portion 6a faces the bottom surface portion 6a ′ toward the top surface side (inside) so that the bottom surface portion 6a ′ can be struck and engaged with the steady-state base material 3 against impact. inclined allowed to form, the lower surface portion 6a 'is in a state of repression engagement with the lower surface of the stopper for the base material 3 shake externally fitted, the temporarily fixed state by the hanging bolt fixing portion 6b and the folded piece 6 c, further It is configured to retain the stopper. For this reason, due to manufacturing errors, the engagement between the thread of the suspension bolt 2 and the engagement claw 6e is loosened or disengaged over a part or almost the entire length of the steady rest base material 3, and the folded piece. Even if it is not possible to maintain a reliable clamping state only by 6c and the suspension bolt fixing part 6b, the steady-state base material 3 is obtained by the engagement of the folded piece 6c and the elastic force of the lower surface part 6a '. Can be firmly fixed and temporarily fixed without inadvertent misalignment.
また、下面部６ａ’は、振れ止め用下地材３の厚さ幅よりも長く、かつ、その先端部を外側に広げて折曲形成されているので、振れ止め用下地材３に仮固定した際に、図４に示す如く下面部６ａ’が、振れ止め用下地材３の下面先端より突出して、その先端角部に対して線上に弾圧係合されるので、さらに挟持状態を確実なものとすることができる。 Further, since the lower surface portion 6a ′ is longer than the thickness width of the steady rest base material 3 and is bent so that its tip end is spread outward, it is temporarily fixed to the steady rest base material 3. In this case, as shown in FIG. 4, the lower surface portion 6a 'protrudes from the lower surface tip of the steady rest base material 3 and is elastically engaged with the tip corner portion on the line. It can be.
また、ビス７によって本固定した状態であっても、折り返し片６ｃ、係合爪６ｅ、下面部６ａ’のそれぞれの係合力が有効に機能するので、ビス７に対する固定強度の依存度を小さくすることができる。その結果、ビス７が緩んでも、吊りボルト２に対して振れ止め用下地材３が位置ずれすることを防止し、吊りボルト２に対する振れ止め用下地材３の固定強度を長期に亘って維持することができる。 Further, even in the state of being permanently fixed with the screws 7, the engaging forces of the folded pieces 6c, the engaging claws 6e, and the lower surface portion 6a ′ function effectively, so that the dependence of the fixing strength on the screws 7 is reduced. be able to. As a result, even if the screw 7 is loosened, the steadying base material 3 is prevented from being displaced with respect to the suspension bolt 2, and the fixing strength of the steadying base material 3 with respect to the suspension bolt 2 is maintained for a long time. be able to.
