Description

【０００１】
【発明の属する技術分野】
本発明は、建物の組み天井の下地の施工において野縁を野縁受に取り付けるための工具に関する。
【０００２】
【従来の技術】
建物の組み天井の下地は、図６、図７または図８に示すように、鋼製の野縁受１００に所定の間隔をおいて設けられた複数の取付金具３００に鋼製の野縁２００を野縁受１００と略直交するように１本ずつ嵌着することにより構成される。取付金具３００は、その各上端部が内側に傾斜して野縁２００の側面の凹部２０２に係合することにより野縁２００を挟持する一対の挟持片３０１を有しており、野縁２００は、下方から取付金具３００に圧入され嵌着される。
【０００３】
野縁２００を取付金具３００に嵌着させる際、野縁２００を下方から押し上げるだけでは、野縁２００を取付金具３００に嵌着させるのに十分な押圧力を与えることが困難であるので、この嵌着を容易にするために、野縁取付具５０が提案されている。
【０００４】
この従来の野縁取付具５０は、図６に示すように、棒状の本体５１の一方端部に平角材からなる２本の肢片５２Ｌ、５２Ｒが接合された長尺の柄５３と、帯状に延びる鋼製プレートの一端部を鉤状に折曲させることにより両肢片５２Ｌ、５２Ｒの上側端からそれぞれ前方へ延出する２個の係止片５４Ｌ、５４Ｒと、両肢片５２Ｌ、５２Ｒの間に架設された平角材からなる押圧部材５５とを有して構成されている。
【０００５】
野縁取付具５０を用いた野縁２００の取付金具３００への取付は、以下の手順で行われる。
まず、野縁２００の両端部を任意の手段で取付金具３００に取り付け、野縁２００を野縁受１００に仮固定する。この両端部の取付は容易に行うことができる。このとき、野縁２００の中間部は、この中間部にある野縁受１００の取り付けられている取付金具３００の真下に位置しているものの嵌着されておらず、若干たわんだ状態となっている。この状態にある野縁受１００と野縁２００とを嵌着させることがこの野縁取付具５０の役目である。そのために、図６、図７に示すように、野縁取付具５０をその係止片５４Ｌ、５４Ｒが前方に延出するように持ち、両肢片５２Ｌ、５２Ｒの間で野縁２００を挟みながら係止片５４Ｌ、５４Ｒを野縁受１００に引掛ける。この状態で、柄５３の下端部を手前側に引き上げる。
これにより、図７に示すように、野縁取付具５０は、係止片５４Ｌ、５４Ｒの先端部を支点Ｐとして、てこのように作用し、押圧部材５５が野縁２００の下面２０１に当って野縁２００を上方へ押圧するので、野縁２００は取付金具３００に圧入され嵌着する。
【０００６】
このように、野縁取付具５０を用いれば、てこの原理が作用することから大きな力を必要とせず野縁２００を取付金具３００に容易に嵌着させることができる。また、長尺の柄５３を介して野縁２００の取付作業を行うことができるので、脚立等の作用台を用いることなく作業を行うことができる。

【０００８】
【発明が解決しようとする課題】
しかしながら、上記の野縁取付具５０には、以下に示す問題点がある。
まず、図７に示すように、押圧部材５５は、平角材であって、柄５３に固定されているので、柄５３を手前側に引き上げると、押圧部材５５は野縁２００の下面２０１に線接触し、この接触面に力が集中するので、野縁２００の下面２０１が凹む等変形することがあるという問題点がある。変形した野縁２００は外観状見苦しくなるので取り替えなければならず、手間と費用がかかるという問題点がある。
【０００９】
また、押圧部材５５と野縁２００が係合し、かつ、押圧部材５５の支点Ｐを中心とする円運動に伴う上方への移動と共に横方向への移動も多少発生するので、野縁２００が押圧部材５５に引っ張られて軸方向に移動することがあるという問題点がある。そのために、移動した野縁２００を元の位置に戻す作業が必要となり、手間がかかるという問題点がある。
【００１０】
更に、図８に示すように、野縁取付具５０は、両肢片５２Ｌ、５２Ｒも平角材であるので、隣合う２本の野縁２００の設置間隔が狭い場合や野縁２００が壁際に設けられている場合には用いることができないという問題点がある。
【００１１】
本発明は、上記課題に鑑みてなされたものであり、野縁を変形させることなく野縁受に取り付けることができるようにすると共に、取付時における野縁の軸方向への移動を抑制することができる野縁取付具を提供することを目的とする。
【００１２】
【課題を解決するための手段】
前記目的を達成するためになされた本発明の請求項１に記載の野縁取付具は、長尺の柄の先端部に、天井に取り付けられている野縁受に引掛ける引掛け部材と、該引掛け部材を前記野縁受に引掛けた状態で前記野縁受の下方で前記野縁受と直交するように配置されている野縁を前記野縁受の方へ押圧する押圧部材とを備えてなる野縁取付具において、前記引掛け部材は、前記野縁の幅より少し大きい間隔をおいて対峙する一対の薄板状の引掛け板と、該引掛け板の上端部に前記柄の軸方向と略直交する方向へ突出する一対の突出部とを有し、前記押圧部材は、前記一対の引掛け板間の下端部に回転自在に設けられた回転軸と、該回転軸に固着され前記野縁の下方に当接する押圧板とを、備えてなることを特徴とするものである。
【００１３】
請求項２に記載の野縁取付具は、請求項１に記載の野縁取付具において、前記引掛け部材の一対の引掛け板間の下端部に底板を設け、該底板に前記長尺の柄の先端部を固定したことを特徴とするものである。
【００１４】
請求項３に記載の野縁取付具は、請求項２に記載の野縁取付具において、前記押圧部材の押圧板は、その回転中心を前記引掛け部材の突出部と反対方向へずらせて回転軸と固着することにより、その突出部側の端部を前記引掛け部材の底板に接触させてその上面を前記突出部側に傾斜させてなることを特徴とするものである。
【００１５】
【発明の実施の形態】
以下、本発明の実施の形態について図面に基づいて説明する。
本実施の形態に係る野縁取付具１は、図１または図２に示すように、鋼製であって、長尺の柄２の先端部に、天井に取り付けられている野縁受１００に引掛ける引掛け部材３と、該引掛け部材３を野縁受１００に引掛けた状態で野縁受１００の下方で野縁受１００と直交するように配置されている野縁２００を野縁受１００の方へ押圧する押圧部材４とを備えている。以下、更に詳細に説明する。
【００１６】
柄２は、図１に示すように、内部が中空の棒体であって、先端部に引掛け部材３及び押圧部材４が設けられ、基端部に持ち手５が設けられている。その長さは、平均的な身長の成人が床上で持ち手５を把持した状態で、先端部が天井の下地に容易に届く程度に設定する。本実施の形態では、柄２を１本の棒体から構成しているが、持ち運び等を考慮して入れ子構造としたり、長さ方向に連結可能とした短尺の棒体を継ぎ合せたりして構成するようにしてもよい。
【００１７】
引掛け部材３は、図１または図２に示すように、対峙する一対の薄板からなる引掛け板６Ｌ、６Ｒと、該一対の引掛け板６Ｌ、６Ｒの上端部に柄２の軸方向と略直交する方向へ突出する一対の突出部７Ｌ、７Ｒを有している。一対の引掛け板６Ｌ、６Ｒの設置間隔は、野縁２００を挟みやすくするために、野縁２００の幅より少し大きくしている。また、一対の引掛け板６Ｌ、６Ｒ間の下端部に底板８を設けると共に、該底板８の下面の中央部に柄２の先端部を固定しているので、柄２の真上に引掛け部材３が位置することとなり、野縁取付具１の省スペース化を図ることができる。
【００１８】
押圧部材４は、図１、図３または図４に示すように、一対の引掛け板６Ｌ、６Ｒ間の下端部に回転自在に設けられた回転軸９と、該回転軸９に固着され野縁２００の下面２０１に当接する押圧板１０とを備えている。
押圧板１０は、引掛け部材３の底板８と略等しい大きさの四角形板であって、その回転中心１０Ｃを引掛け部材３の一対の突出部７Ｌ、７Ｒと反対方向へずらせて回転軸９と固着することにより、その突出部側の端部１１を自重によって引掛け部材３の底板８の接触させて、その上面１２を突出部側に傾斜させている。引掛け部材３の一対の突出部７Ｌ、７Ｒと押圧板１０の回転中心１０Ｃまでの垂直距離は、野縁受１００の上面１０１から取付後の野縁２００の下面２０１までの距離より大きくし、引掛け部材３の一対の突出部７Ｌ、７Ｒを野縁受１００に引掛け易くしている。なお、上面１２は野縁２００との摩擦を少なくするために滑らかにしておくことが望ましい。
また、本実施の形態では、回転軸９を固定軸９Ａと該固定軸９Ａに回転自在に環装された管体９Ｂから構成し、該管体９Ｂに押圧板１０を固着しているが、これに限定されるものではない。
【００１９】
上記構成からなる野縁取付具１を用いた野縁２００の野縁受１００への取付は、以下の手順で行う。
まず、図２、図３に示すように、予め長尺な野縁２００の両端部を、任意の手段で天井に取り付けられている野縁受１００に所定間隔で固定されている取付金具３００に取り付けて、野縁２００を野縁受１００の下方で野縁受１００と直交するように野縁受１００の仮固定する。このとき、野縁２００の中間部は、取付金具３００の真下に位置しているがまだ嵌着されておらず、若干たわんだ状態となっている。
次いで、図３に示すように、一対の突出部７Ｌ、７Ｒが前方を向くように把持して、野縁取付具１を持ち上げ、一対の引掛け板６Ｌ、６Ｒで野縁２００を挟みながら、柄２の先端部を若干手前に倒すようにして一対の突出部７Ｌ、７Ｒを野縁受１００の上面１０１に引掛けると共に、図４に示すように、その突出部側の端部１１が野縁２００の下面２０１に当接するまで押圧板１０を回転させて、上面１２を野縁２００の下面２０１と面接触させる。
【００２０】
この状態で、図４、図５に示すように、柄２を手前側に引き上げると、野縁取付具１は、一対の引掛け板６Ｌ、６Ｒと野縁受１００との接触点を支点Ｐとして作用し、押圧板１０が野縁２００を上方へ押圧する。これにより、野縁２００が取付金具３００に圧入されて、取付金具３００の挟持片３０１と野縁２００の凹部２０２とが係合し、野縁２００が取付金具３００に嵌着される。
このとき、図４に示すように、柄２及び引掛け部材３は支点Ｐを中心として回転するが、押圧板１０は、引掛け部材３に対して回転自在であり、力が加えられた状態で野縁２００の下面２０１と滑らかに面接触しているので、柄２及び引掛け部材３と共に回転せず、野縁２００の下面２０１と面接触した状態で手前側に摺動する。
【００２１】
以上のようにして、順次中間部にある取付金具３００と野縁２００を嵌着させてゆくことにより、野縁２００を、複数の取付金具３００を介して野縁受１００に取り付けることができる。
【００２２】
野縁取付具１を用いれば、図３、図４に示すように、野縁受１００に引掛け部材３を引掛けて、柄２を手前に引き上げるだけで、野縁２００は押圧板１０に押圧されて取付金具３００に嵌着される。柄２の引き上げの際、押圧板１０は野縁２００の下面２０１と面接触した状態を保ちながら摺動するので、この接触面に荷重が集中することはない。したがって、野縁２００の下面２０１に凹み等の変形を生じさせることなく、また、野縁２００が押圧板１０と係合してその軸方向へ引っ張られることもない。
【００２３】
また、野縁取付具１は、図５に示すように、引掛け部材３のの一対の引掛け板６Ｌ、６Ｒを薄板で構成しているので、隣合う２本の野縁２００の設置間隔が狭い場合や野縁２００が壁際に設けられている場合にも用いることができる。
【００２４】
更に、図３に示すように、押圧板１０の回転中心１０Ｃを引掛け部材３の一対の突出部７Ｌ、７Ｒと反対方向へずらせて回転軸９と固着しているので、野縁取付具１を野縁受１００及び野縁２００から取り外すだけで、そのアンバランスな自重によって押圧板１０の突出部側の端部１１が底板８と接触するまで突出部側に回転するので、その上面１２は一対の突出部７Ｌ、７Ｒ側に傾斜した状態に自然に復帰する。これにより、野縁取付具１を持ち上げたままの状態で作業をすることができ、作業のスピードアップを図ることができる。
【００２５】
【発明の効果】
以上説明したように、本発明の請求項１に記載の野縁取付具によれば、押圧部材を回転自在としているので、野縁の下面との接触面積を大きくすることができ、この接触面に力が集中することを防止して、野縁の下面が凹む等変形することを防止することができるという利点がある。
【００２６】
また、押圧板が野縁の下面に沿って摺動するので、野縁がその軸方向に引っ張られることがないという利点がある。
これらにより、野縁を取り替える等の手間を省くことができるので、作業性を向上させ、コストダウンを図ることができるという利点がある。
【００２７】
更に、引掛け部材の引掛け板を薄板状としているので、隣合う２本の野縁の設置間隔が狭い場合や野縁が壁際に設けられている場合であっても用いることができるという利点がある。
【００２８】
請求項２に記載の野縁取付具によれば、柄の真上に引掛け部材が位置することなり、野縁取付具の省スペース化を図ることができるという利点がある。
【００２９】
請求項３に記載の野縁取付具によれば、野縁取付具を野縁受及び野縁から取り外すだけで、押圧板は、そのアンバランスな自重によって、その上面が突出部側に傾斜した状態に自然に復帰するので、野縁取付具を持ち上げたままの状態で作業をすることができ、作業性を向上させることができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for attaching a ridge to a ridge in the construction of a base of a building ceiling.
[0002]
[Prior art]
As shown in FIG. 6, FIG. 7 or FIG. 8, the base of the assembled ceiling of the building is provided with a plurality of mounting brackets 300 provided at predetermined intervals on a steel ridge 100. Are fitted one by one so as to be substantially orthogonal to the field margin receiver 100. The mounting bracket 300 has a pair of holding pieces 301 for holding the wild edge 200 by each upper end thereof being inclined inward and engaging with the concave portion 202 on the side surface of the wild edge 200. , Is pressed into the fitting 300 from below and fitted.
[0003]
When fitting the ridge 200 to the mounting bracket 300, it is difficult to apply a sufficient pressing force to fit the ridge 200 to the mounting bracket 300 only by pushing up the ridge 200 from below. In order to facilitate the fitting, a ridge fitting 50 has been proposed.
[0004]
As shown in FIG. 6, the conventional field edge attachment 50 includes a long handle 53 in which two limbs 52 L and 52 R made of a rectangular material are joined to one end of a rod-shaped body 51, and a strip-shaped body. The two locking pieces 54L, 54R extending forward from the upper ends of the two limb pieces 52L, 52R, respectively, by bending one end of the steel plate extending in a hook shape, and the two limb pieces 52L, 52R. And a pressing member 55 made of a flat rectangular material installed between them.
[0005]
The mounting of the ridge 200 to the mounting bracket 300 using the ridge mounting tool 50 is performed in the following procedure.
First, both ends of the ridge 200 are attached to the mounting bracket 300 by any means, and the ridge 200 is temporarily fixed to the ridge holder 100. The mounting of both ends can be easily performed. At this time, the middle portion of the bezel 200 is located just below the mounting bracket 300 to which the bezel support 100 in this middle portion is attached, but is not fitted, and is slightly bent. I have. The role of the field edge attachment 50 is to fit the field edge receiver 100 and the field edge 200 in this state. For this purpose, as shown in FIGS. 6 and 7, the field edge attachment 50 is held so that the locking pieces 54L and 54R extend forward, and the field edge 200 is sandwiched between the two limb pieces 52L and 52R. The hooking pieces 54L, 54R are hooked on the field edge support 100 while being held. In this state, the lower end of the handle 53 is pulled up to the near side.
As a result, as shown in FIG. 7, the edge fitting 50 acts as a lever with the tips of the locking pieces 54L and 54R as the fulcrum P, and the pressing member 55 contacts the lower surface 201 of the edge 200. Since the ridge 200 is pressed upward, the ridge 200 is press-fitted into the mounting bracket 300 and fitted.
[0006]
As described above, the use of the field edge attachment 50 allows the field edge 200 to be easily fitted to the attachment fitting 300 without requiring a large force because the principle of leverage acts. In addition, since the work of attaching the rim 200 can be performed via the long handle 53, the work can be performed without using an operation table such as a stepladder.
[0007]

[0008]
[Problems to be solved by the invention]
However, the above-mentioned edge fitting 50 has the following problems.
First, as shown in FIG. 7, since the pressing member 55 is a flat rectangular member and is fixed to the handle 53, when the handle 53 is pulled up to the near side, the pressing member 55 is drawn on the lower surface 201 of the field edge 200 by a line. Since the contact is made and the force is concentrated on this contact surface, there is a problem that the lower surface 201 of the ridge 200 may be deformed such as being dented. The deformed rim 200 has a problem that it has to be replaced because it becomes unsightly in appearance and requires labor and cost.
[0009]
Further, since the pressing member 55 and the ridge 200 are engaged with each other, and the upward movement associated with the circular movement about the fulcrum P of the pressing member 55 and the lateral movement occur to some extent, the ridge 200 is There is a problem that it may be moved in the axial direction by being pulled by the pressing member 55. Therefore, it is necessary to return the moved rim 200 to its original position, which is troublesome.
[0010]
Furthermore, as shown in FIG. 8, since the ridge pieces 50 L of the limb pieces 52 L and 52 R are also flat, as shown in FIG. There is a problem that it cannot be used when it is provided.
[0011]
The present invention has been made in view of the above problems, and enables to attach to a field margin receiver without deforming the field edge, and to suppress movement of the field edge in the axial direction at the time of attachment.

The pair of protrusions 7L and 7R are hooked on the upper surface 101 of the field edge support 100 so that the tip of the handle 2 is tilted slightly forward, and as shown in FIG. The pressing plate 10 is rotated until it comes into contact with the lower surface 201 of the edge 200, and the upper surface 12 is brought into surface contact with the lower surface 201 of the field edge 200.
[0020]
In this state, as shown in FIGS. 4 and 5, when the handle 2 is pulled up to the near side, the flank mounting fixture 1 makes the contact point between the pair of hooking plates 6L, 6R and the flank support 100 a fulcrum P. The pressing plate 10 presses the ridge 200 upward. As a result, the ridge 200 is press-fitted into the mounting bracket 300, the holding piece 301 of the mounting bracket 300 and the concave portion 202 of the ridge 200 are engaged, and the ridge 200 is fitted to the mounting bracket 300.
At this time, as shown in FIG. 4, the handle 2 and the hook member 3 rotate around the fulcrum P, but the pressing plate 10 is rotatable with respect to the hook member 3, and the force is applied. , And smoothly slides in contact with the lower surface 201 of the ridge 200, does not rotate with the handle 2 and the hooking member 3, and slides toward the near side in a state of being in surface contact with the lower surface 201 of the ridge 200.
[0021]
As described above, by sequentially fitting the mounting bracket 300 and the ridge 200 at the intermediate portion, the ridge 200 can be mounted on the ridge holder 100 via the plurality of mounting brackets 300.
[0022]
3 and 4, the hook member 3 is hooked on the hook member 100 and the handle 2 is simply pulled up, so that the hook edge 200 is attached to the pressing plate 10 as shown in FIGS. It is pressed and fitted to the mounting bracket 300. When the handle 2 is pulled up, the pressing plate 10 slides while maintaining the surface contact with the lower surface 201 of the field edge 200, so that the load does not concentrate on this contact surface. Therefore, the lower surface 201 of the ridge 200 does not deform such as a dent, and the ridge 200 does not engage with the pressing plate 10 and is not pulled in the axial direction.
[0023]
In addition, as shown in FIG. 5, the pair of hooking plates 6L and 6R of the hooking member 3 of the field edge attachment 1 is formed of a thin plate, so that the installation interval between two adjacent field edges 200 is set. Can be used when the edge is narrow or when the edge 200 is provided near the wall.
[0024]
Furthermore, as shown in FIG. 3, since the rotation center 10 C of the pressing plate 10 is displaced in the opposite direction to the pair of protrusions 7 L, 7 R of the hook member 3 and is fixed to the rotation shaft 9, Is simply removed from the ridge holder 100 and the ridge 200, and the unbalanced own weight rotates the protruding end 11 of the pressing plate 10 toward the protruding portion until it comes into contact with the bottom plate 8, so that the upper surface 12 is It naturally returns to the state inclined to the pair of protrusions 7L and 7R. Thus, the work can be performed with the ridge fitting 1 raised, and the speed of the work can be increased.
[0025]
【The invention's effect】
As described above, according to the field edge attachment according to claim 1 of the present invention, since the pressing member is rotatable, the contact area with the lower surface of the field edge can be increased, and this contact surface can be increased. Therefore, there is an advantage that it is possible to prevent the force from being concentrated on the lower surface and prevent the lower surface of the field edge from being deformed such as being dented.
[0026]
Further, since the pressing plate slides along the lower surface of the field edge, there is an advantage that the field edge is not pulled in the axial direction.
By these means, it is possible to save labor such as replacement of a field margin, so that there is an advantage that workability can be improved and cost can be reduced.
[0027]
Furthermore, since the hooking plate of the hooking member is formed in a thin plate shape, it can be used even when the interval between two adjacent ridges is narrow or when the ridges are provided near a wall. There is.
[0028]
According to the field edge attachment according to the second aspect, the hooking member is located directly above the handle, and there is an advantage that the space of the field edge attachment can be saved.
[0029]
According to the field edge mounting device of the third aspect, the upper surface of the pressing plate is inclined toward the protruding portion by the unbalanced own weight only by removing the field edge mounting device from the field edge support and the field edge. Since the work returns naturally to the state, the work can be performed with the field edge mounting tool raised, and the workability can be improved.
