Description

【0001】
【発明の属する技術分野】
この発明は、例えばALCパネル等を建築物の外壁として躯体に取付ける金具等を、パネルに螺着するためのアンカーを埋設する穴を形成するのに用いる穿孔用治具に関する。
【0002】
【従来の技術】
ALCパネル等を建築物の外壁として躯体に取付ける工法として、例えば図4に示すごとく、パネル21の長手方向端部近傍に取付金具25を螺着し、この金具を建築物の躯体梁に固着した定規アングルに取着する乾式工法がある。この工法における取付金具25の螺着手段としては、まずパネル21の長辺小口面21−1から直角方向に、パネル面と平行で、パネル中心よりもやや深いアンカー埋設穴22を長尺のドリルを使用して形成し、次いでパネル裏面から前記穴22に直交するボルト孔23を穿孔した後、パネル長辺小口面21−1に開口している前記アンカー埋設穴22から、パイプ状で中心部にねじ孔が穿設されたアンカー24を挿入し、パネル裏面に開口している前記ボルト孔23から、取付金具25を挿通したボルト26を挿入し前記ねじ孔に螺着している。
【0003】
【発明が解決しようとする課題】
この工法は、パネル面に貫通孔がないので、貫通孔から浸水したり、パネル表面に亀裂が発生することはないが、工場で予めアンカー埋設穴22とボルト孔23を穿孔しておく場合は、穿孔位置の融通性が乏しく、また、建築現場で穿孔する場合には所望位置に穿孔可能であるが、厚さ100mm前後のパネルの小口面から深さ400mm程度のアンカー埋設穴22を位置精度よく形成し、さらにこの穴に向ってパネル裏面からボルト穴23を穿孔して直交させるには、高度な熟練を要し、手間がかかるという問題があった。
【0004】
この発明は、上記した従来の問題を解決するためになされたもので、パネルの長辺小口面から直角方向に形成するアンカー埋設穴と、パネル裏面から前記穴に直交するボルト孔を位置精度よく容易に形成することが可能なパネル穿孔用治具を提供しようとするものである。
【0005】
【課題を解決するための手段】
この発明に係るパネル穿孔用治具は、パネルの表面と長辺小口面(側面)に凹凸嵌合方式にて容易に着脱可能となすとともに、パネルに嵌合固定した状態で長辺小口面にアンカー埋設穴を、パネル裏面にボルト孔をそれぞれ手間をかけずに位置精度よく形成することができる治具であり、その要旨は、パネル幅よりも長い治具本体の両端部に、パネルの相対する長辺小口面を挟持して該小口面と直角方向に治具本体を固定する把持機構を備え、かつ治具本体の一方の端部には、前記アンカー埋設穴形成用の穿孔刃を治具本体の長手方向にガイドするガイド機構を有し、治具本体の上面にはその中心線上にボルト孔穿孔用の長孔を設けたことを特徴とし、また、前記把持機構は、一方は治具本体に固定され、他方は治具本体に長手方向にスライド可能に装着されて治具本体にねじ止め可能となすとともに、把持部にパネル幅に応じて一定のパネル押圧力をスプリングにて付与する押圧機構を備えていることを特徴とし、さらに前記ガイド機構は、形成するアンカー埋設穴の直径よりもやや大きい内径を有し、かつ底面に切欠きを有するガイド筒体を備え、治具本体に着脱可能となしていることを特徴とするものである。
【0006】
この発明における把持機構は、パネル幅よりも長い治具本体の裏面、すなわちパネル面と相対する面に、パネルの表面と長辺小口面に当接するL字形の金具を取付ける。この場合、長辺小口面にアンカー埋設穴を形成する側のL字形金具は、治具本体に固着されており、反対側のL字形金具は、パネル幅に対応できるように所定の位置にスライド可能となしている。すなわち、この発明の把持機構は、一方は固定把持部とし、他方は可動把持部となしたものである。
【0007】
固定把持部を構成するL字形金具に設ける穿孔刃のガイド機構は、当該L字形金具の長辺小口面に当接する垂直面に接するごとく治具本体にボルト等にて着脱可能に取付けられたブラケットに、アンカー埋設穴の直径よりもやや大きい内径を有し、かつ底面に切欠きを有するガイド筒体を治具本体の中心線と合致する位置に取付け、穿孔刃(ドリル)を前記ブラケット、ガイド筒体およびL字形金具を貫通させて治具本体の長手方向に直角にガイドできる構造となっている。
【0008】
なお、穿孔刃のガイド機構を治具本体に着脱可能としたのは、パネルの厚さの変動に対応できるようにするためである。すなわち、パネルの厚さが異なると当然アンカー埋設穴の形成位置が変わってくるため、パネルの厚さに応じて専用のガイド機構を取替え使用できるようにするためである。また、ガイド筒体の底面に切欠きを形成したのは、穿孔中に発生したパネル切粉を円滑に排出させるためである。
【0009】
一方、可動把持部は、L字形金具をパネル小口面に圧接させる押圧機構と、この押圧機構を治具本体の長手方向中心線上に穿設した長孔に沿ってスライドさせてパネル面に固定する摺動機構とから構成されている。前記押圧機構は、L字形金具を治具本体上面に穿設した長孔に沿って摺動可能に設けるとともに、このL字形金具と一体的に取付けられ、常時固定把持部側へ押圧力を付勢するスプリング付きレバーと、このレバーを所定の位置に脱着可能に係止する係合金具とから構成され、パネル幅の変動に応じて可動のL字形金具の押圧力を調整できるようになっている。
【0010】
また、前記摺動機構は、前記係合金具に螺着した止めねじが治具本体上面に穿設した長孔に沿って摺動可能となすとともに、この止めねじにて前記係合金具を締付けて治具本体に固定できる構造となっており、パネル幅に応じて可動のL字形金具を所定の位置に固定できるようになっている。
【0011】
この発明の穿孔用治具は、前記固定把持部と可動把持部とでパネルの相対する長辺小口面を把持して直角方向に固定できるとともに、幅の異なるパネルでも同じ押圧力で固定することができる。また、前記固定把持部に着脱可能に設けたガイド機構により、穿孔刃(ドリル)をパネルの長辺小口面に直角方向に保持できるとともに、その長辺小口面から精度よくアンカー埋設穴を形成することができる。さらに、穿孔刃のガイド機構を取替え可能としたことにより、パネルの厚さが異なってもその厚さに合わせたガイド機構を用いることにより容易に対応できる。また、治具本体に穿設した長孔を利用してパネル面から前記アンカー埋設穴に直交するボルト孔を精度よく穿孔することができる。
【0012】
【発明の実施の形態】
図1はこの発明に係るパネル穿孔用治具の一例を示す斜視図、図2は図1に示すパネル穿孔用治具をパネルに取付けた状態を示す縦断側面図、図3は同じく図1に示すパネル穿孔用治具をパネルに取付けた状態を示す平面図であり、1はパネル穿孔用治具、2は治具本体、3は長孔、4は固定L字形金具、5は可動L字形金具、6はガイド用ブラケット、7はボルト、8はガイド筒体、9は押圧用レバー、10はスプリング、11は係合金具、12は止めねじである。
【0013】
すなわち、パネル穿孔用治具1は、断面凹形の細長いチャンネル状で、パネル11の最大幅よりも長尺の部材からなり、かつ上面にボルト孔穿孔用の長孔3をその中心線上に穿設した治具本体2と、この治具本体の一端に当該治具本体と直角に固着した適当長さの固定L字形金具4および穿孔刃(ドリル)のガイド機構からなる固定把持部と、同治具本体の他端に当該治具本体の長手方向にスライド可能に取付けた可動L字形金具5および該金具を所定の位置にねじ止め可能となし、かつパネル小口面に圧接させる押圧機構を具備した可動把持部とから構成されている。
【0014】
固定把持部を構成する固定L字形金具4は、治具本体2の端部裏面にボルトまたは溶接等により固着しており、その垂直面には治具本体2の長手方向中心線の真下の所定高さ位置に穿孔用の孔4−1が穿設されている。このL字形金具4の垂直面には、前記穿孔用の孔4−1と同一中心線上にこれと同じ穿孔用の孔6−1が穿設された断面逆凹形のガイド用ブラケット6を該金具より外側に突出した金具端部にボルト7により固着し、その内側にアンカー埋設穴よりやや大きい内径を有し、かつ底面に切粉排出用の切欠8−1を有するガイド筒体8をボルトまたは溶接等により固着している。このガイド用ブラケット6およびガイド筒体8からなるガイド機構は、パネルの厚さに合わせて必要数製作する。
【0015】
可動把持部を構成する可動L字形金具5は、パネル面に相対する水平片5−1の端部に、治具本体の上面中心線上に穿設したボルト孔穿孔用の長孔3にスライド可能に貫通する断面逆凹形のガイド部5−2を有し、このガイド部5−2を介して治具本体2の長手方向に移動可能に装着するとともに、前記ガイド部5−2部に緩貫通した押圧用レバー9を介して、治具本体2の上面にスライド可能に装着した係合金具11と接続され、かつ前記押圧用レバー9に外嵌したスプリング10にて常時固定把持部側へ押圧力が付勢されるように、押圧用レバー9の取手部9−1を前記係合金具11に設けた複数の係止凹部11−1に前記スプリング10に抗して着脱可能に係止できるようになっている。また、係合金具11には、該金具の端部に突設した水平板11−2に止めねじ12が螺着され、この止めねじ12を締付けることにより治具本体背面側に取付けたプレート11−3とにより治具本体2に固定できるようになっている。
【0016】
すなわち、この可動把持部は、パネル幅に応じて可動のL字形金具5を所定の位置に固定できるようになっており、かつスプリング力によりこのL字形金具5のパネル小口面に対する押圧力を調整できるようになっている。
【0017】
上記構造のパネル穿孔用治具の使用に際しては、まず止めねじ120緩め、固定把持部と可動把持部の間隔をパネル幅に応じた寸法に開き、押圧用レバー9を開いておく。この状態でパネル21の裏面に治具本体をセットするが、その際、固定把持部を構成する固定L字形金具4の垂直面をパネル21の長辺小口面21−1に当接させ、治具本体2の中心線がパネルの短辺小口面21−2から所望の寸法となるように位置決めした後、可動把持部を構成する可動L字形金具5にてこの側の長辺小口面21−1に当接して挟持させ、止めねじ12を締付けて係合金具11を固定する。続いて、押圧用レバー9をスプリング10に抗して固定把持部側へ引いて適当な係止凹部11−1に嵌入することにより、可動L字形金具5がスプリング力によりパネル小口面に押圧固定される。
【0018】
次に、穿孔刃である電動ドリル(図面省略)を固定把持部側のガイド筒体8に挿入して駆動させれば、穿孔刃はガイド筒体8にガイドされて治具本体2の中心線上をパネル面と平行に穿孔を開始する。この時発生する切粉はガイド筒体8の切欠8−1から排出される。そして、所望の深さに穿孔してアンカー埋設穴22を形成する。続いて、電動ドリルを治具本体2の長孔3の所定位置にセットし、下方に向って垂直に穿孔すれば、先に形成したアンカー埋設穴22に直交したボルト孔23を穿設することができる。
【0019】
アンカー埋設穴22およびボルト孔23の穿孔作業が終了すると、係合金具11に係止している押圧用レバー9を係止凹部11−1から離脱させて可動L字形金具5の押圧力を解除し、パネル穿孔用治具をパネルから取外す。
【0020】
なお、この発明装置における固定把持部と可動把持部の間隔は、最大幅の約1/2まで変更可能に設けることができる。また、穿孔作業をより正確、迅速に行うために、長孔3の側端面に固定L字形金具5からの寸法を示す目盛を付し、固定L字形金具5の上面に治具本体2の中心線からの目盛を付すと便利である。
【0021】
【発明の効果】
以上説明したごとく、この発明のパネル穿孔用治具は、以下に記載する効果を奏する。
(1)固定把持部と可動把持部とでパネルの相対する長辺小口面を把持して直角方向に固定できるとともに、幅の異なるパネルでも同じ押圧力で固定することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a drilling jig used for forming a hole for embedding an anchor for screwing, for example, a metal fitting for attaching an ALC panel or the like to an enclosure as an outer wall of a building.
[0002]
[Prior art]
As a method of attaching an ALC panel or the like to an enclosure as an outer wall of a building, for example, as shown in FIG. 4, an attachment fitting 25 is screwed in the vicinity of the longitudinal end of the panel 21, and the fitting is fixed to the building beam of the building. There is a dry method that attaches to the ruler angle. As a screwing means of the mounting bracket 25 in this construction method, first, an anchor burial hole 22 that is parallel to the panel surface and is slightly deeper than the center of the panel in a direction perpendicular to the long side edge surface 21-1 of the panel 21 is a long drill. And then drilling a bolt hole 23 perpendicular to the hole 22 from the back side of the panel, and then from the anchor embedding hole 22 opened to the small edge surface 21-1 of the panel, in the shape of a pipe. An anchor 24 having a screw hole is inserted into the bolt hole 23, and a bolt 26 inserted through a mounting bracket 25 is inserted from the bolt hole 23 opened on the back surface of the panel and screwed into the screw hole.
[0003]
[Problems to be solved by the invention]
Since this method does not have through holes on the panel surface, it will not be flooded from the through holes or cracks will be generated on the panel surface. However, when the anchor embedded hole 22 and the bolt hole 23 are previously drilled at the factory, In addition, the flexibility of the drilling position is poor, and when drilling at a construction site, it is possible to drill at a desired position, but the anchor embedding hole 22 having a depth of about 400 mm is positioned from the small face of the panel having a thickness of about 100 mm. In order to form well and to make the bolt hole 23 perpendicular to the hole from the back side of the panel in the direction of this hole, there is a problem that it requires a high degree of skill and takes time and effort.
[0004]
The present invention has been made to solve the above-described conventional problems. An anchor embedding hole formed in a direction perpendicular to the long edge of the panel and a bolt hole orthogonal to the hole from the back of the panel are positioned with high accuracy. An object of the present invention is to provide a panel drilling jig that can be easily formed.
[0005]
[Means for Solving the Problems]
The panel drilling jig according to the present invention can be easily attached to and detached from the surface of the panel and the long side edge surface (side surface) by a concave-convex fitting method, and the long side edge surface is fitted and fixed to the panel. An anchor embedding hole is a jig that can form a bolt hole on the back of the panel without any trouble, and the gist of this is the relative position of the panel at both ends of the jig body longer than the panel width. A holding mechanism for holding the jig main body in a direction perpendicular to the small edge surface, and fixing the drilling blade for forming the anchor embedding hole at one end of the jig main body. The jig body has a guide mechanism for guiding in the longitudinal direction, and a long hole for drilling a bolt hole is provided on the center line of the upper surface of the jig body, and one of the gripping mechanisms is cured. The other is fixed to the tool body, and the other is The guide mechanism is provided with a pressing mechanism that is mounted so that it can be screwed to the jig main body, and a fixed panel pressing force is applied to the grip portion according to the panel width by a spring. Is characterized by having a guide cylinder having an inner diameter slightly larger than the diameter of the anchor embedding hole to be formed and having a notch on the bottom surface, and being detachable from the jig body.
[0006]
In the gripping mechanism according to the present invention, an L-shaped metal fitting that comes into contact with the front surface of the panel and the long edge of the long side is attached to the back surface of the jig body longer than the panel width, that is, the surface facing the panel surface. In this case, the L-shaped bracket on the side where the anchor embedding hole is formed in the long side edge is fixed to the jig body, and the L-shaped bracket on the opposite side is slid to a predetermined position so as to correspond to the panel width. It is possible. That is, in the gripping mechanism of the present invention, one is a fixed gripping portion and the other is a movable gripping portion.
[0007]
The guide mechanism of the drilling blade provided on the L-shaped bracket constituting the fixed gripping part is a bracket that is detachably attached to the jig main body with a bolt or the like so as to contact the vertical surface that abuts on the long edge of the L-shaped bracket. In addition, a guide cylinder having an inner diameter slightly larger than the diameter of the anchor embedding hole and having a notch on the bottom surface is attached to a position that matches the center line of the jig body, and a drilling blade (drill) is attached to the bracket and guide. It has a structure in which the cylindrical body and the L-shaped metal fitting can be penetrated and guided at right angles to the longitudinal direction of the jig body.
[0008]
The reason why the guide mechanism of the drilling blade can be attached to and detached from the jig main body is to cope with fluctuations in the thickness of the panel. That is, if the panel thickness is different, the formation position of the anchor embedding hole is naturally changed, so that a dedicated guide mechanism can be replaced and used according to the panel thickness. The reason why the notch is formed on the bottom surface of the guide cylinder is to smoothly discharge the panel chips generated during drilling.
[0009]
On the other hand, the movable gripping part is fixed to the panel surface by sliding a pressing mechanism that presses the L-shaped metal fitting against the facet of the panel and a long hole formed on the longitudinal center line of the jig body. And a sliding mechanism. The pressing mechanism is slidably provided along an elongated hole drilled in the upper surface of the jig body, and is attached integrally with the L-shaped bracket to constantly apply a pressing force to the fixed gripping portion side. It is composed of a lever with a spring to be urged and an engagement fitting that detachably locks the lever at a predetermined position, so that the pressing force of the movable L-shaped fitting can be adjusted according to the fluctuation of the panel width. Yes.
[0010]
In addition, the sliding mechanism allows a set screw screwed to the engagement fitting to slide along a long hole drilled in the upper surface of the jig body, and the engagement fitting is tightened with the set screw. Thus, the movable L-shaped bracket can be fixed at a predetermined position according to the panel width.
[0011]
The punching jig according to the present invention can hold the opposite long side edge surface of the panel by the fixed gripping portion and the movable gripping portion and fix it in a right angle direction, and can also fix the panels having different widths with the same pressing force. Can do. Moreover, the guide mechanism provided detachably on the fixed grip portion can hold the drilling blade (drill) in a direction perpendicular to the long edge of the panel, and the anchor embedding hole can be accurately formed from the long edge of the long edge. be able to. Further, since the guide mechanism of the drilling blade can be replaced, it is possible to easily cope with the difference in the thickness of the panel by using a guide mechanism adapted to the thickness. Moreover, the bolt hole orthogonal to the said anchor embedding hole can be precisely drilled from the panel surface using the long hole drilled in the jig body.
[0012]
