【０００１】
【産業の利用分野】
本発明はアンカー金具埋込みＡＬＣパネルに関する。詳しくは、主に建物躯体を取り付けるためのアンカー金具をパネル内の一本の補強筋に係止し、埋設する際、簡単に係止することができるアンカー金具埋込みＡＬＣパネルに関するものである。
【０００２】
【従来の技術】
ＡＬＣパネル（以下、パネルという）内には、パネルを建物躯体に取り付けるためのナットなどの雌ねじ部を有するアンカー金具が、予めパネル内の補強筋に係止、固定されて埋設されている。
その埋設されるアンカー金具を補強筋に係止、固定する際は、通常は引抜き強度を考慮して２本の補強筋に係止させることが多い。しかし、あまり大きな引抜き強度が要求されないパネルの場合や補強筋が太くかつアンカー金具の強靱性が大きい場合等は、アンカー金具を１本の補強筋に固定することも可能である。その１例として、実開平１−８３８１７号公報に示されているように、ナットの下部に補強鉄筋を貫通させ、それを他の補強鉄筋と共に配筋し、パネル内に埋設して建物躯体に取り付けるための係止具とするものが提案されている。また、それによってアンカー金具の取付強度を強くし、材料の簡素化などを図ることを目的としている。
【０００３】
【発明が解決しようとする課題】
しかし、実開平１−８３８１７号公報におけるアンカー金具は、１本の補強鉄筋をナットの下部に貫通させて構成するものであるため、ナットに補強鉄筋を予め貫通させた後、パネルに埋設する補強鉄筋マットまたは篭などを製作する必要がある。そのため、ナットの下部に貫通孔を開ける穿孔加工、その貫通孔に貫通させる補強鉄筋の準備、その貫通孔に補強鉄筋を貫通させる工程、貫通させた後に貫通孔と補強鉄筋とを固定する工程、それを補強鉄筋マットまたは篭に取り付ける工程などが必要となる。したがって、このような多数の工程が必要であるため、アンカー金具の取付け作業が大変であるとともに、特に自動取り付けが困難である。
【０００４】
また、このようなナットは雌ねじ部とボルト挿入用筒部と貫通孔用とが必要であるためかなり長いナットが必要となる。したがって、汎用性のナットは使用できず特別に製作する必要があるため、コスト面も高いものとなる。さらには、アンカー金具にメッキ処理が必要な場合は、底部に開口部がないためメッキ液が中に入り難く均一なメッキ処理が困難になるなどの問題点もある。
【０００５】
そこで、本発明の目的はＡＬＣパネル内に埋設されるアンカー金具を補強鉄筋の１本に係止する際の以上のような問題点をなくし、補強鉄筋マット製作後でも容易に係止でき、特に自動取り付けを可能にするとともに、アンカー金具の製作コストが安価でパネルのコストが低減するアンカー金具埋込みＡＬＣパネルを提供することにある。
【０００６】
【課題を解決するための手段】
以上のような課題を解決する本発明の構成は、雌ねじ部、筒状部および係止部から成るアンカー金具がＡＬＣパネル内の補強筋に係止、固定されてそのパネル内に埋設されているアンカー金具埋込みＡＬＣパネルにおいて、前記筒状部および係止部は凹部が形成された一対の鋼板が相対するように接合されて構成され、前記係止部に前記補強筋が嵌め込まれる開口部が設けられており、アンカー金具は前記係止部にその開口部から嵌め込まれて把持または狭持された１本の補強筋に対して係止され且つ溶接又はかしめにより固定されているアンカー金具埋込みＡＬＣパネルから成る。
【０００７】
以下、本発明の作用について説明する。
アンカー金具の係止部に開口部を有するため、補強筋をその開口部から嵌め込むだけで係止されるとともに、アンカー金具を１本の補強筋に対して係止するのみで良いため、アンカー金具の補強筋への取り付けが容易になる。特に、補強筋をマットや篭状に形成させた後でも取付け可能となることから、アンカー金具の自動取付けが容易になる。また、１本の補強筋に対して係止するためアンカー金具の係止部を小さくでき、さらには貫通孔を開ける穿孔加工なども必要がないため、アンカー金具の製作コストが安価にできる。
【０００８】
【発明の実施の形態】
以下、図に基づいて本発明の実施の形態を説明する。
図１に示すアンカー金具Ｋの実施形態は、雌ねじ部１となるナットと、そのナットの外周を包むように構成している筒状部２と、その筒状部２の下部に逆Ｕ字型に形成された係止部３と、筒状部２の底部が開口して筒状部２と係止部３と連通する連通孔４とから成っている。そして、アンカー金具Ｋは、その係止部３が図８に示すように、ＡＬＣパネルＰの１本の補強鉄筋５（横鉄筋）に係止されている。また補強鉄筋５は係止部３の開口部３ａから嵌め込まれて把持または狭持された状態で係止されているとともに、係止部３に対して溶接で固定されている。
【０００９】
なお、係止部３の形状は、図１においては補強鉄筋５が嵌め込む開口部３ａを有する略逆Ｕ字型を成しているが、図５に示すような略Ｃ字型、または図６に示すような開口部３ａの両端部が中側奥に折り曲げられてハの字型を形成していると、引抜き耐力が増大し、素材や大きさによっては溶接による固定なしに係止され得るという効果も奏する。特に、図６に示すような係止部３はアンカー金具Ｋを補強鉄筋５の上側から押し込むのみで係止されるため、係止作業性の面でも優れておりその自動化が容易になる。
【０００１０】
また、図４および図５に示すように、係止部３の開口部３ａが外方向拡がりの形状になっていると、補強鉄筋５とアンカー金具Ｋとの位置が多少ずれても補強鉄筋５を係止部に嵌め込むことが可能となる。したがって、移動するライン上での自動取り付け時のように、補強鉄筋５とアンカー金具Ｋの位置関係が動き易い、すなわち位置がずれ易いような場合に特に有効である。なお、図示していないが、図６に示すような係止部３においても図４に示すように開口部３ａを広くしても良い。
【００１１】
さらに、図７に示すように、係止部３は補強鉄筋５が係合する間隔を有して２つに分離されているとともに相対する一対の略Ｃ字型を構成していると、補強鉄筋５の両面から把持または狭持されるため、両側の剪断耐力が大きくなり、より強固に取り付けられる。この実施形態においても、係止部３が強靱に素材の場合は溶接固定を省略することも可能である。また、図７に示す実施形態において、間隔を補強鉄筋５の直径よりも大きくするか、または間隔の入り口がハ文字型に形成されている（図示せず）ことが、前記と同様に補強鉄筋５の嵌め込みをさらに容易にし、その自動化を可能にする点でより望ましい。
なお、図７に示す実施形態において、補強鉄筋５を係止部３に係止させる際は、両係止部３の間に補強鉄筋５を嵌め込んだ後、アンカー金具Ｋを横方向に回転させる。
【００１２】
以上の実施の形態においては、アンカー金具Ｋの雌ねじ部１以外の筒状部２、係止部３および連通孔４などは、中央部から下部に渡って連続して凹部が形成されている同形の一対の鋼板６が相対して溶接によって接合されて形成されている。このようにして形成されるアンカー金具Ｋは、雌ねじ部１の長さや直径が変化しても筒状部２、係止部３および連通孔４を容易に形成可能になるとともに、アンカー金具Ｋの製作コストを低減できる。また、一対の鋼板６の筒状部２に相当する以外の所定位置に、ピンホール８や小切欠き部（図示せず）などを形成しておくと、一対の鋼板６を接合する際、正確に一致させることが容易になる。さらに、図１および図３のように鋼板６の横側端部を折り曲げたものは、鋼板６同士の接合面がその折曲片によって塞がれるため、接合状態が不完全な場合でもその面からＡＬＣスラリーが侵入するのが防止される。
【００１３】
また、筒状部２の下部に係止部３に連通する連通孔４が設けられていると、アンカー金具にメッキ処理が必要な場合、メッキ液が中に入り易くかつ液が循環するため、均一なメッキ処理が可能となる。
さらに、連通孔４が設けられている場合、図３（ロ）に示す拡大図のように、係止部３の両端上部の鋼板６の外側面にプレス加工されたプレス部７が設けられていることが、次の理由からより望ましい。すなわち、補強鉄筋５は通常丸棒であるが、一方の２枚の鋼板を係合させて係止部３を形成させる際は、その凹部を完全に丸くすることが難しいため、係止部３と補強鉄筋５との間に隙間が生じ易い。その結果、その隙間からＡＬＣスラリーが連通孔４を通して筒状部２内に侵入し、雄ねじ（図示せず）の挿入、螺合に支障を生じさせる。これに対し、係止部３上部の鋼板６の外側面をプレス加工することにより係止部２の凹部がより丸くなり、補強鉄筋５と係止部３の凹部との間に隙間が無くなる。その結果、上記のような支障が解消する。
【００１４】
また、図１および図２に示すように、筒状部２の上部の所定位置に、外側に凸部の段差９を有していることが望ましい。すなわち、筒状部２の上部にはナットなどの雌ねじ部１が設けられているが、パネルの厚みとの関係で通常はアンカー金具Ｋ全体の長さを規制する必要があるため、一定位置に凸部の段差９を有しているとナットなどの雌ねじ部１をその段差９に位置させて固定することにより、正確にかつ容易に位置設定が可能となる。
【００１５】
なお、本発明に係るアンカー金具Ｋの雌ねじ部はナットに限定されず、筒体の上部に雌ねじ部を形成させても良い。また雌ねじ部以外の筒状部などは、上記実施の態様のような一対の鋼板６による筒状部２に限定されず、円管などの既成の筒状体を適用しても良い。
また、ＡＬＣパネルＰ内の補強筋に係止、固定する手段は手動による係止、固定でも自動固定でもよく、補強筋マットの形成後でも前でも良い。固定は通常は溶接によるが、かしめる方法でも良く、さらには係止部の構造によっては溶接固定を省いても良い。
また、アンカー金具Ｋの材質や雌ねじ部の長さは限定されないが、市販のＪＩＳの短尺ナット（８〜１４ｍｍ程度の高さ）などがコスト面でも好適である。
【００１６】
【発明の効果】
本発明によれば、アンカー金具を１本の補強筋に対して係止する構造であるため係止作業が簡単になり、また係止部を小さくできるため安価になる。さらに、アンカー金具の係止部に開口部を有するため、補強筋をその開口部から嵌め込むだけで係止でき、補強筋への取り付けが容易になる。また補強筋をマットや篭状に形成させた後でも取付け可能となることから、自動取り付けが容易になる。さらに、凹部が形成された一対の鋼板が相対するように接合されて構成されているので、筒状部および係止部が簡単に製作できるためアンカー金具の製作コストが安価になり、かつ形状を自由に変形可能となる。
【００１７】
係止部を略Ｃ字型、略逆Ｕ字型と成すとともにその開口部の両端部を中側奥に折り曲げてハの字型を形成した型にすると、係止作業が簡単であるとともに、万一溶接による固定効果が無くなった場合でも、外れることがないため、安全性が高まる。また略Ｃ字型を相対して一対にした型においても、安全性向上が可能となる。

[Industrial application fields]
The present invention relates to an anchor metal embedded ALC panel. More specifically, the present invention relates to an anchor metal fitting embedded ALC panel that can be easily locked when an anchor metal fitting for attaching a building frame is locked to one reinforcing bar in the panel and embedded.
[0002]
[Prior art]
In an ALC panel (hereinafter referred to as a panel), an anchor metal fitting having a female screw portion such as a nut for attaching the panel to a building frame is embedded in advance by being locked and fixed to a reinforcing bar in the panel.
When locking and fixing the embedded anchor fitting to the reinforcing bar, the anchor metal is usually locked to the two reinforcing bars in consideration of the pulling strength. However, in the case of a panel that does not require a very high drawing strength, or when the reinforcing bar is thick and the anchor metal has high toughness, the anchor metal can be fixed to one reinforcing bar. As an example, as shown in Japanese Utility Model Laid-Open No. 1-83817, a reinforcing reinforcing bar is passed through the lower part of the nut, and the reinforcing reinforcing bar is laid together with other reinforcing reinforcing bars. What is made into the latching tool for attaching is proposed. In addition, the purpose is to increase the mounting strength of the anchor fitting and simplify the material.
[0003]
[Problems to be solved by the invention]
However, the anchor fitting in Japanese Utility Model Laid-Open No. 1-83817 is constructed by penetrating one reinforcing bar through the lower part of the nut, so that the reinforcing bar is embedded in the panel after the reinforcing bar is passed through the nut in advance. Reinforcing bar mats or fences need to be made. Therefore, drilling to open a through hole in the lower part of the nut, preparation of a reinforcing rebar to be penetrated through the through hole, a step of passing the reinforcing rebar through the through hole, a step of fixing the through hole and the reinforcing rebar after being penetrated The process etc. which attach it to a reinforcing bar mat or a hook are needed. Therefore, since such a large number of steps are necessary, the mounting work of the anchor metal is difficult, and automatic mounting is particularly difficult.
[0004]
Further, since such a nut requires a female screw part, a bolt insertion cylinder part and a through hole, a considerably long nut is required. Therefore, a versatile nut cannot be used and needs to be specially manufactured, so that the cost is high. Further, when the anchor metal needs to be plated, there is no problem that the uniform plating process becomes difficult because the plating solution is difficult to enter because there is no opening at the bottom.
[0005]
Therefore, the object of the present invention is to eliminate the above-described problems when the anchor metal fitting embedded in the ALC panel is locked to one of the reinforcing reinforcing bars, and can be easily locked even after the reinforcing reinforcing bar mat is manufactured. An object of the present invention is to provide an anchor fitting embedded ALC panel that enables automatic attachment and that the manufacturing cost of the anchor fitting is low and the cost of the panel is reduced.
[0006]
[Means for Solving the Problems]
In the configuration of the present invention that solves the above-described problems, an anchor fitting composed of a female thread portion, a cylindrical portion, and a locking portion is locked and fixed to a reinforcing bar in the ALC panel and is embedded in the panel. In the anchor metal fitting embedded ALC panel, the cylindrical portion and the locking portion are configured such that a pair of steel plates in which concave portions are formed are opposed to each other, and an opening in which the reinforcing bar is fitted is provided in the locking portion. It is in and, anchor the anchor embedded ALC panels which are secured by engagement by and welded or caulked against one reinforcement that is grasped or clamped fitted through the opening in the locking portion Consists of.
[0007]
The operation of the present invention will be described below.
Since the anchor metal has an opening at the locking portion, the reinforcing bar can be locked only by fitting the opening from the opening, and the anchor metal only needs to be locked to one reinforcing bar. It is easy to attach the bracket to the reinforcing bar. In particular, since the reinforcing bars can be attached even after the reinforcing bars are formed in a mat or bowl shape, the automatic attachment of the anchor fittings is facilitated. In addition, since the locking portion of the anchor fitting can be made small because it is locked to a single reinforcing bar, and further, there is no need for drilling or the like to open a through hole, the manufacturing cost of the anchor fitting can be reduced.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The embodiment of the anchor fitting K shown in FIG. 1 has a nut that becomes the female thread portion 1, a cylindrical portion 2 that is configured to wrap the outer periphery of the nut, and an inverted U-shape at the bottom of the cylindrical portion 2. The formed locking portion 3 and the bottom portion of the cylindrical portion 2 are opened and the cylindrical portion 2 and a communication hole 4 communicating with the locking portion 3 are formed. And as for the anchor metal fitting K, the latching | locking part 3 is latched by the one reinforcing bar 5 (horizontal bar) of ALC panel P, as shown in FIG. The reinforcing reinforcing bars 5 are fitted in the openings 3 a of the locking portions 3 and locked in a gripped or pinched state, and are fixed to the locking portions 3 by welding.
[0009]
In addition, although the shape of the latching | locking part 3 has comprised the substantially reverse U-shape which has the opening part 3a in which the reinforcing bar 5 fits in FIG. 1, it is substantially C-shaped as shown in FIG. When the both ends of the opening 3a as shown in FIG. 6 are bent inwardly to form a square shape, the pulling strength increases, and depending on the material and size, it is locked without being fixed by welding. There is also an effect of obtaining. In particular, the locking portion 3 as shown in FIG. 6 is locked only by pushing the anchor metal fitting K from the upper side of the reinforcing steel bar 5, so that it is excellent in terms of locking workability and is easy to automate.
[00010]
Further, as shown in FIGS. 4 and 5, when the opening 3a of the locking portion 3 has an outwardly expanding shape, the reinforcing reinforcing bar 5 even if the positions of the reinforcing reinforcing bar 5 and the anchor fitting K are slightly shifted. Can be fitted into the locking portion. Therefore, it is particularly effective when the positional relationship between the reinforcing reinforcing bar 5 and the anchor fitting K is easy to move, that is, the position is likely to be shifted, as in automatic attachment on a moving line. Although not shown, the opening 3a may be widened in the locking portion 3 as shown in FIG. 6 as shown in FIG.
[0011]
Further, as shown in FIG. 7, the locking portion 3 is separated into two parts with a spacing with which the reinforcing reinforcing bars 5 are engaged, and a pair of substantially C-shaped members that are opposed to each other is used as a reinforcing member. Since the reinforcing bars 5 are gripped or sandwiched from both sides, the shear strength on both sides is increased and the reinforcing bars 5 are attached more firmly. Also in this embodiment, when the locking portion 3 is a tough material, the welding fixing can be omitted. Further, in the embodiment shown in FIG. 7, the reinforcing reinforcing bars are similar to the above in that the interval is made larger than the diameter of the reinforcing reinforcing bars 5 or the entrance of the interval is formed in a letter C shape (not shown). 5 is more desirable in that it can be more easily fitted and can be automated.
In the embodiment shown in FIG. 7, when the reinforcing reinforcing bars 5 are locked to the locking portions 3, after the reinforcing reinforcing bars 5 are fitted between the locking portions 3, the anchor fitting K is rotated in the lateral direction. Let
[0012]
In the above embodiment, the cylindrical part 2 other than the female thread part 1 of the anchor fitting K, the locking part 3, the communication hole 4, and the like have the same shape in which a concave part is continuously formed from the central part to the lower part. The pair of steel plates 6 are joined to each other by welding. The anchor fitting K formed in this way can easily form the cylindrical portion 2, the locking portion 3 and the communication hole 4 even if the length and diameter of the female screw portion 1 are changed. Manufacturing cost can be reduced. Further, when a pinhole 8 or a small notch (not shown) is formed at a predetermined position other than that corresponding to the cylindrical portion 2 of the pair of steel plates 6, when the pair of steel plates 6 are joined, It becomes easy to match exactly. 1 and 3, the lateral end of the steel plate 6 is folded, because the joined surfaces of the steel plates 6 are blocked by the bent pieces, even if the joined state is incomplete. Intrusion of ALC slurry from the
[0013]
In addition, when the communicating hole 4 communicating with the locking part 3 is provided at the lower part of the cylindrical part 2, when plating processing is required for the anchor metal fitting, the plating solution easily enters and the liquid circulates. A uniform plating process is possible.
Further, when the communication hole 4 is provided, as shown in the enlarged view of FIG. 3 (b), a press part 7 that is press-worked is provided on the outer surface of the steel plate 6 at both upper ends of the locking part 3. It is more desirable for the following reasons. That is, the reinforcing steel bars 5 are usually round bars, but when the two steel plates are engaged to form the locking portion 3, it is difficult to completely round the concave portion. And the reinforcing steel bars 5 are likely to have a gap. As a result, the ALC slurry enters the cylindrical portion 2 through the communication hole 4 from the gap, causing trouble in insertion and screwing of a male screw (not shown). On the other hand, by pressing the outer surface of the steel plate 6 on the upper part of the locking part 3, the concave part of the locking part 2 becomes more round, and there is no gap between the reinforcing bar 5 and the concave part of the locking part 3. As a result, the above problems are solved.
[0014]
Further, as shown in FIGS. 1 and 2, it is desirable to have a step 9 on the outer side at a predetermined position on the upper portion of the cylindrical portion 2. That is, an internal thread portion 1 such as a nut is provided on the upper portion of the cylindrical portion 2, but it is usually necessary to regulate the length of the entire anchor fitting K in relation to the thickness of the panel. If the convex portion has the step 9, the female screw portion 1 such as a nut is positioned at the step 9 and fixed, so that the position can be set accurately and easily.
[0015]
In addition, the internal thread part of the anchor metal fitting K which concerns on this invention is not limited to a nut, You may form an internal thread part in the upper part of a cylinder. In addition, the cylindrical portion other than the female screw portion is not limited to the cylindrical portion 2 formed by the pair of steel plates 6 as in the above embodiment, and an existing cylindrical body such as a circular pipe may be applied.
The means for locking and fixing to the reinforcing bars in the ALC panel P may be manual locking, fixing or automatic fixing, or may be after or before the reinforcing bar mat is formed. The fixing is usually by welding, but a caulking method may be used, and further, welding fixing may be omitted depending on the structure of the locking portion.
Moreover, although the material of the anchor metal fitting K and the length of the female screw portion are not limited, a commercially available JIS short nut (height of about 8 to 14 mm) or the like is suitable in terms of cost.
[0016]
【The invention's effect】
According to the present invention, since the anchor fitting is locked to one reinforcing bar, the locking operation is simplified, and the locking portion can be made small, so that it is inexpensive. Further, since the anchor metal has an opening in the locking portion, the reinforcing bar can be locked only by being fitted from the opening, and attachment to the reinforcing bar becomes easy. In addition, since the reinforcing bars can be attached even after they are formed in a mat or bowl shape, automatic attachment becomes easy. Furthermore, since a pair of steel plates with recesses are joined so as to face each other, the cylindrical portion and the locking portion can be easily manufactured, so that the manufacturing cost of the anchor metal fitting is reduced and the shape is reduced. It can be freely deformed.
[0017]
When the locking part is formed into a substantially C-shaped, substantially inverted U-shaped, and both ends of the opening are bent into the inner side to form a square shape, the locking operation is simple , even if the fixing effect by one million welding is exhausted, because there is no deviate, security is enhanced. Also in the mold which is in a pair relative to a substantially C-shaped, it is possible to all of safe improved.
