Description

【０００１】
【発明の属する技術分野】
本発明は、メタルラスなどのメッシュ素材を蓋状部材に簡便に固定する固定方法に関する。
ここで、本発明においては、メタルラスの他にも、エキスパンドメタル、金網などのメッシュ素材を総称してメタルラスと呼ぶものとする。
【０００２】
【従来の技術】
メタルラスは、本来、主にしっくい、モルタルなどの下地用に用いられる素材で、図４に示すような網目（メッシュ）状の金属材である。ここで、メッシュ３１は、ボンド３２から伸びる複数のストランド３３が別のボンド３２に連なっていくことによって構成されている。
【０００３】
メタルラスは、一般に鋼板などの薄板を素材として常温引伸切断法によって製造される。
このメタルラスを蓋状部材に固定する方法としては、リベットあるいはボルトで固定する方法と溶接によって固定する方法とがある。ここで、溶接方法としては、スポット溶接が最も一般的であり、他に、ティグ溶接、アーク溶接（以上、電気溶接）とガス溶接などがある。
【０００４】
図５を例として、従来のメタルラスと蓋状部材の固定方法を説明する。
図５は、半円形の蓋状部材２に半筒状にしたメタルラス３を固定する様子を示している。ここで、図を簡略とするため、メタルラス３のメッシュ構造を省略して記載している（以下、同じ）。
蓋状部材２とメタルラス３の固定には、溶接が最も簡便な方法であるが、溶接には、下記のような問題がある。
【０００５】
スポット溶接などの電気溶接では、蓋状部材が金属であることが必要であり、各部材の表面に被覆のないことが要求される。また、溶接は、美観上の観点から内面側を溶接することが要求され、図５に代表されるような複雑な形状では、内面側の奥まで溶接用電極を近づけることは困難である。
また、ガス溶接においては、溶接位置以外にも溶接の熱が拡がってしまい、仕上がりの外観が悪く、溶接後の手直しが不可欠となる。さらに、熱が広範囲に拡がるため熱歪みによってメタルラスが変形してしまうトラブルも発生する。
【０００６】
そのため、リベット、ボルトなどで固定する方法が用いられるが、ボルトで固定する方法では、メタルラスの内面側にあらかじめナットを溶接等で取り付けておく必要があり、更に、取付時に、そのナットとボルトの位置合わせが難しいという問題がある。
一方、リベットは、例えば図２に示す外観のものが用いられ、図３に示すように、２枚の板状材４６、４７と必要に応じワッシャ４５を重ね、その取り付け孔にリベット４を挿入し、マンドレル４１を引き抜くことでボディ部４３をひしゃげさせ、そのひしゃげたボディ部４３とフランジ部４２とで板状材４６、４７をかしめて接合するものである。
【０００７】
このリベットで固定する方法も簡便であるが、メタルラスの固定においては、リベットのひしゃげたボディ部がメタルラスのストランド部に確実にかかるようにしっかりとかしめることが困難であり、また、ストランド部に確実にかかっているかどうかの判別もつきにくい。そのため、メタルラスにあらかじめワッシャーなどを溶接しておくことも行われるが、やはり位置決めが難しくなり、作業性も悪いためコストアップの要因となっている。
【０００８】
【発明が解決しようとする課題】
本発明は、以上に述べたような悪い作業性を改善し、簡便で確実なメタルラスと蓋状部材の固定方法を提供し、作業能率を向上させ、低コスト化を実現することを目的とする。
【０００９】
【課題を解決するための手段】
本発明は、蓋状部材にあらかじめ取付部材を取り付けておくことで、蓋状部材の側面部と取付部材でメタルラスを容易に、かつ、確実に挟み込むことができるようになることに着目してなされたものである。
すなわち、本発明は、あらかじめ蓋状部材の側面部に必要数だけメタルラス固定用孔を設け、その孔に対向するようにそれぞれの取付部材のメタルラス固定用孔を位置決めして前記蓋状部材の内側の底面部に前記取付部材を固定しておいて、メタルラスの端部が蓋状部材の側面部と取付部材に挟持されるようにメタルラスを蓋状部材に装入し、前記蓋状部材の外部から蓋状部材のメタルラス固定用孔それぞれにリベットまたはボルトを差し込み、メタルラスのいずれかの間隙部と取付部材のメタルラス固定用孔を挿通させて固着し、蓋状部材の側面部と取付部材にメタルラスが挟持して固定されるようにしたことを特徴とするメタルラスと蓋状部材の固定方法によって上記課題を解決したのである。
【００１０】
また、前記取付部材を、その側面部にメタルラス固定用孔を有し底面部に位置決め用の２つ以上の孔を有した略Ｌ字状の金具とし、前記蓋状部材の底面部に、その側面部に設けられたメタルラス固定用孔の位置決め用として、前記取付部材の位置決め用の２つ以上の孔に対応し、かつ、該孔の径を小さくした張り出し部をあらかじめ加工しておくことが好ましいことを見出したのである。
【００１１】
そして、前記取付部材の底面部に設けた位置決め用の２つ以上の孔の径が互いに異なっており、その異なった径に対応して、前記張り出し部の底面部に設けた張り出し部の径が同様に異なるようにすることで、あらかじめ取り付けておく取付部材の取付が容易になることを見出したのである。
さらに、前記蓋状部材の側面部に必要数だけ設けられたメタルラス固定用孔と前記取付部材のメタルラス固定用孔がメタルラスのメッシュ間隔以上の長さの長孔とすることで、メタルラスと蓋状部材の固定時の作業性が更に向上することを見出したのである。
【００１２】
【発明の実施の形態】
本発明のメタルラスの固定方法を図１に示す手順に従って説明する。
図１では、半円状の蓋状部材へのメタルラスの本発明による固定方法を示している。
まず、図１（ａ）に示すように、あらかじめ蓋状部材２の側面部にメタルラス固定用孔２１を所用数だけあけておく。次に、それらのメタルラス固定用孔２１に合わせて蓋状部材２の底面部に位置決め用張り出し部２２、２３をそれぞれ加工する。この位置決め用張り出し部は、取付部材１の位置決め孔１２、１３に対応させて、メタルラス固定用孔１１とメタルラス固定用孔２１の位置が合うようにそれぞれ加工しておく。このメタルラス固定用孔１１とメタルラス固定用孔２１は円形状でも良いが、メタルラスのメッシュ間隔以上の長さとした長円とすることが好ましい。
【００１３】
位置決め用張り出し部２２、２３の径は、その張り出し部に合わせる取付部材１の位置決め孔１２、１３の径より小さくしておき、かつ、位置決め用張り出し部２２、２３の径を異ならせるようにしておくことで、さらに位置決めを容易にすることができる。ここで、取付部材１の位置決め孔１２、１３の径は、位置決め用張り出し部２２、２３の径にあわせて異ならせておくことは当然のことである。
【００１４】
取付部材１の蓋状部材２への取付は、スポット溶接とすることが作業性から最も好ましいが、ボルト、リベットなどで固定するようにしても良い。
このように、あらかじめ取付部材１を取り付けておいた蓋状部材２にメタルラス３を装入し（図１（ｂ））、蓋状部材２の外部からリベットなどでかしめて蓋状部材２とメタルラス３を固定する（図１（ｃ））のである。
【００１５】
このようにすることで、リベットなどがメタルラスのメッシュ内を通るようにさえしておけば、厳密な位置あわせは不要であり、きわめて簡便に蓋状部材とメタルラスの固定を行うことができるのである。
本発明の固定方法は、各種形状の蓋状部材へのメタルラスの固定に適用することが可能である。図６に、そのいくつかの例を示す。図６（ａ）は円形の蓋状部材、図６（ｂ）は四角形の蓋状部材への適用例を示している。また、図６（ｃ）はメタルラスが円錐台形（いわゆるメガホン形）の場合についての適用を示している。
【００１６】
メタルラスのメッシュ形状は、リベット、ボルトなどを通すことが可能であれば、任意の形状で良いが、ダイヤ型、亀甲型などの形状が好ましい。
また、メタルラスの材質は、特に限定しないが、鉄板、表面処理鋼板、ステンレス鋼板、アルミニウムなどがあげられる。
さらに、本発明は網状の素材を蓋状部材に固定する方法として汎用的に適用することが可能であり、網状の素材として非金属の素材を適用することも可能であることは言うまでもない。
【００１７】
蓋状部材の材質は、作業性の観点から、取付部材をスポット溶接することが可能な金属製とすることが望ましいが、それに限定されるわけではなく、ＡＢＳ樹脂製などのプラスティック製等であっても良い。
【００１８】
【実施例】
実際に適用した例として、図１に示す半円形状の蓋状部材２にメタルラス３を固定する場合について説明する。本適用例で用いた取付部材１の実寸法を図７に図面化して示す。蓋状部材に取り付けるメタルラスのメッシュ間隔を１０ｍｍとしたため、取付部材１のメタルラス固定用孔１１と、蓋状部材２のメタルラス固定用孔２１はそれぞれ１０ｍｍ長さの長孔としている。取付部材１の位置決め孔１２、１３は、それぞれ ３．２ｍｍφ、 ４．２ｍｍφとしており、蓋状部材２の位置決め用張り出し部２２、２３の径はそれより若干小さく形成している。そして、取付部材１を蓋状部材２に位置決めして、スポット溶接で固定した。
【００１９】
あらかじめ、蓋状部材２を上記のように加工しておいたため、メタルラス３と蓋状部材２の取付そのものはきわめて簡便に行うことができ、作業性を大幅に向上させることができた。
作業時間は７０％低減でき、従来の３０％となった。
【００２０】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fixing method for easily fixing a mesh material such as a metal lath to a lid member.
Here, in the present invention, in addition to the metal lath, a mesh material such as an expanded metal or a wire mesh is generally referred to as a metal lath.
[0002]
[Prior art]
The metal lath is a material mainly used for the base such as plaster and mortar, and is a mesh-shaped metal material as shown in FIG. Here, the mesh 31 is configured by a plurality of strands 33 extending from the bond 32 continuing to another bond 32.
[0003]
The metal lath is generally manufactured by a cold drawing method using a thin plate such as a steel plate as a raw material.
As a method of fixing the metal lath to the lid-like member, there are a method of fixing with a rivet or a bolt and a method of fixing by welding. Here, spot welding is the most common welding method, and also includes TIG welding, arc welding (above, electric welding) and gas welding.
[0004]
With reference to FIG. 5 as an example, a conventional method of fixing a metal lath to a lid-like member will be described.
FIG. 5 shows a state in which the metal lath 3 having a semi-cylindrical shape is fixed to the semi-circular lid-like member 2. Here, in order to simplify the drawing, the mesh structure of the metal lath 3 is omitted (the same applies hereinafter).
Welding is the simplest method for fixing the lid-like member 2 and the metal lath 3, but welding has the following problems.
[0005]
In electric welding such as spot welding, the lid-like member needs to be made of metal, and it is required that the surface of each member has no coating. In addition, welding requires that the inner surface be welded from the viewpoint of aesthetics, and it is difficult to bring the welding electrode as far as the inner surface with a complicated shape as represented in FIG.
Further, in gas welding, the heat of welding spreads to a position other than the welding position, and the appearance of the finish is poor, and rework after welding is indispensable. Further, since the heat spreads over a wide range, there is a problem that the metal lath is deformed due to thermal distortion.
[0006]
Therefore, the method of fixing with rivets, bolts, etc. is used, but in the method of fixing with bolts, it is necessary to attach a nut to the inner surface side of the metal lath in advance by welding or the like. There is a problem that alignment is difficult.
On the other hand, for the rivet, for example, the one shown in FIG. 2 is used. As shown in FIG. 3, two plate-like members 46 and 47 are overlapped with a washer 45 if necessary, and the rivet 4 is inserted into the mounting hole. By pulling out the mandrel 41, the body 43 is shaved, and the shaky body 43 and the flange 42 caulk and join the plate-like members 46, 47.
[0007]
This method of fixing with rivets is also easy, but it is difficult to fix the metal lath firmly so that the shaved body of the rivet is securely engaged with the strand of the metal lath. It is difficult to determine whether or not you are suffering from. For this reason, a washer or the like is welded to the metal lath in advance. However, the positioning is also difficult, and the workability is poor.
[0008]
[Problems to be solved by the invention]
An object of the present invention is to improve the poor workability as described above, provide a simple and reliable method of fixing the metal lath and the lid-like member, improve the work efficiency, and realize a low cost. .
[0009]
[Means for Solving the Problems]
The present invention has been made by paying attention to the fact that the metal lath can be easily and reliably sandwiched between the side surface portion of the lid-shaped member and the mounting member by attaching the mounting member to the lid-shaped member in advance. It is a thing.
That is, according to the present invention, the required number of metal lath fixing holes are provided in advance on the side surface of the lid member, and the metal lath fixing holes of the respective mounting members are positioned so as to face the holes, and the inside of the lid member is positioned. The metal lath is inserted into the lid so that the end of the metal lath is sandwiched between the side surface of the lid and the mounting member, and the outside of the lid is fixed to the bottom of the lid. A rivet or bolt is inserted into each of the metal lath fixing holes of the lid member, and the metal lath fixing hole of the mounting member is inserted through one of the gaps of the metal lath and fixed, and the metal lath is fixed to the side portion of the lid member and the mounting member. This problem has been solved by a method of fixing a metal lath and a lid-like member, characterized in that the metal lath and the lid-like member are fixed.
[0010]
Further, the mounting member is a substantially L-shaped metal fitting having a metal lath fixing hole on a side surface thereof and two or more holes for positioning on a bottom surface thereof. For positioning of the metal lath fixing hole provided on the side surface portion, it is possible to previously process an overhang portion corresponding to two or more holes for positioning of the mounting member and reducing the diameter of the hole. I found it to be favorable.
[0011]
The two or more positioning holes provided on the bottom surface of the mounting member have different diameters, and the diameter of the overhang provided on the bottom of the overhang is corresponding to the different diameter. Similarly, it has been found that by making them different from each other, it is easy to mount a mounting member that is mounted in advance.
Further, the metal lath fixing holes provided in a required number on the side surface portions of the lid-like member and the metal lath fixing holes of the mounting member are elongated holes having a length equal to or longer than the mesh interval of the metal lath, so that the metal lath and the lid-shaped They have found that workability when fixing the members is further improved.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
The method for fixing the metal lath of the present invention will be described according to the procedure shown in FIG.
FIG. 1 shows a method for fixing a metal lath to a semicircular lid-like member according to the present invention.
First, as shown in FIG. 1A, the required number of metal lath fixing holes 21 are previously formed in the side surface of the lid-like member 2. Next, positioning projections 22 and 23 are formed on the bottom surface of the lid-like member 2 in accordance with the metal lath fixing holes 21. The positioning projections are machined so as to correspond to the positioning holes 12 and 13 of the mounting member 1 so that the positions of the metal lath fixing holes 11 and 21 are matched. The metal lath fixing hole 11 and the metal lath fixing hole 21 may have a circular shape, but it is preferable that the metal lath fixing hole 11 and the metal lath fixing hole 21 have an oval length longer than the mesh interval of the metal lath.
[0013]
The diameters of the positioning projections 22 and 23 are made smaller than the diameters of the positioning holes 12 and 13 of the mounting member 1 that match the projections, and the diameters of the positioning projections 22 and 23 are made different. By doing so, positioning can be further facilitated. Here, it is natural that the diameters of the positioning holes 12 and 13 of the mounting member 1 are made different according to the diameters of the positioning projections 22 and 23.
[0014]
The attachment of the attachment member 1 to the lid-like member 2 is most preferably performed by spot welding from the viewpoint of workability, but it may be fixed with bolts, rivets, or the like.
As described above, the metal lath 3 is inserted into the lid member 2 to which the mounting member 1 has been attached in advance (FIG. 1B), and the lid member 2 and the metal lath are caulked from the outside of the lid member 2 with rivets or the like. 3 is fixed (FIG. 1 (c)).
[0015]
By doing so, strict positioning is not required as long as the rivets and the like pass through the mesh of the metal lath, and the lid-like member and the metal lath can be fixed extremely easily. .
The fixing method of the present invention can be applied to fixing metal laths to lid members having various shapes. FIG. 6 shows some examples. FIG. 6A shows an example of application to a circular lid-like member, and FIG. 6B shows an example of application to a square lid-like member. FIG. 6C shows an application in the case where the metal lath has a truncated cone shape (a so-called megaphone shape).
[0016]
The mesh shape of the metal lath may be any shape as long as it can pass through rivets, bolts, and the like, but is preferably a diamond shape, a tortoiseshell shape, or the like.
The material of the metal lath is not particularly limited, and examples thereof include an iron plate, a surface-treated steel plate, a stainless steel plate, and aluminum.
Furthermore, the present invention can be generally applied as a method of fixing a net-like material to a lid-like member, and it goes without saying that a non-metallic material can be applied as a net-like material.
[0017]
From the viewpoint of workability, it is desirable that the material of the lid-like member is made of a metal to which the attachment member can be spot-welded, but is not limited thereto, and is made of a plastic such as ABS resin. May be.
[0018]
【Example】
As an example of actual application, a case where a metal lath 3 is fixed to a semicircular lid-like member 2 shown in FIG. 1 will be described. FIG. 7 shows the actual dimensions of the mounting member 1 used in this application example. Since the mesh interval of the metal laths to be attached to the lid member is set to 10 mm, the metal lath fixing holes 11 of the mounting member 1 and the metal lath fixing holes 21 of the lid member 2 are long holes each having a length of 10 mm. The positioning holes 12 and 13 of the mounting member 1 are 3.2 mmφ and 4.2 mmφ, respectively, and the diameters of the positioning projections 22 and 23 of the lid member 2 are formed slightly smaller. Then, the mounting member 1 was positioned on the lid member 2 and fixed by spot welding.
[0019]
Since the lid-like member 2 was previously processed as described above, the attachment of the metal lath 3 and the lid-like member 2 itself could be performed extremely easily, and the workability was greatly improved.
The working time can be reduced by 70%, which is 30% of the conventional one.
[0020]
【The invention's effect】
By applying the method of the present invention, workability was greatly improved, work efficiency was improved, and cost reduction was realized.
