<P>PROBLEM TO BE SOLVED: To provide an anchor for a plaster board, which can reduce the possibility of destruction of the plaster board when a rotation prevention member is driven into the plaster board, and which makes workability in embedment excellent because a precedent cloth-cutting operation becomes unnecessary when the rotation stopper member is driven into the cloth-stuck plaster board. <P>SOLUTION: The anchor 1 for the plaster board includes an anchor body 4 which has a female screw portion 4b on an inner periphery and which is inserted into the drilled hole 3a of the plaster board 3, and the rotation stopper member 5 which is integrally provided in the anchor body 4 and which is driven into the plaster board 3 so as to stop the rotation of the anchor body 4 when the anchor body 4 is inserted into the drilled hole 3a of the plaster board 3. The rotation prevention member 5 has a cutting edge portion 5a undergoing sharp cutting edge working at a driving-direction leading end. When the rotation prevention member 5 is driven into the plaster board 3, it cuts the cloth 8 by itself, and sticks sharply into the plaster board 3. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、石膏ボードに埋設される石膏ボード用アンカーに関する。   The present invention relates to a gypsum board anchor embedded in a gypsum board.

近年、建築物の内壁は、下地材として石膏ボードを貼り付け、その表面にクロスなどの仕上げ材を貼り付けた構造が多用されている。このような内壁にタオル掛け用のフック、カーテンレール、薄型ＴＶの吊持金具などを取り付ける場合には、石膏ボードに石膏ボード用アンカーを埋設し、該石膏ボード用アンカーに対して取り付け用のネジをねじ込む必要がある。その理由は、石膏ボードが強度的に脆いため、取り付け用のネジを直接ねじ込んでも、十分な固定強度を得ることができないからである。   In recent years, a structure in which a gypsum board is pasted as a base material and a finishing material such as a cloth is pasted on the surface of an inner wall of a building is often used. When attaching a hook for hanging a towel, curtain rail, thin TV suspension bracket, etc. to such an inner wall, a gypsum board anchor is buried in the gypsum board and a screw for attaching to the gypsum board anchor is attached. Need to be screwed in. The reason is that the gypsum board is brittle in strength, so that sufficient fixing strength cannot be obtained even if the mounting screws are directly screwed in.

石膏ボード用アンカーとしては、アンカー本体を石膏ボードの取付け孔に対して、樹脂接着剤を含浸させて硬化させた後に、直にねじ込むタイプ（例えば、特許文献１参照）や、石膏ボードの穿設孔に樹脂アンカーを注入すると共に、該樹脂アンカー中にアンカー本体を挿入し、樹脂アンカーの硬化によって必要な固定強度を得るタイプが知られている。後者は、樹脂アンカーを併用するため、前者に比べて強度的に有利であるが、取り付け用ネジのねじ込みに際し、共回りの惧れがあるので、回り止め手段が必要である。   As the anchor for gypsum board, the anchor body is impregnated with a resin adhesive in the mounting hole of the gypsum board and cured, and then directly screwed (for example, see Patent Document 1), or the gypsum board is drilled. There is known a type in which a resin anchor is injected into a hole, an anchor body is inserted into the resin anchor, and a necessary fixing strength is obtained by hardening the resin anchor. Since the latter uses a resin anchor in combination, it is more advantageous in strength than the former. However, when the mounting screw is screwed in, there is a possibility of co-rotation, so that a detent means is necessary.

一方、上記の回り止め手段としては、ＡＬＣの外壁に先端側部分を突出させて埋設される長尺な埋込ボルトの埋設部分に取り付けられて、埋込ボルトを回り止めするための回り止め部材が知られている。このものは、ＡＬＣの外壁専用に平板状の金属プレートで形成されており、その工法もＡＬＣに埋設孔を開けて樹脂アンカーを注入し、埋込ボルトの埋設部分を挿入し、回り止め部材部分を打ち込みして、埋設部分とＡＬＣとを直接凝固結合させても、回り止め機能と抜け止め機能を同時に満たすことができる。
しかしながら、石膏ボードは、ＡＬＣに比べ非常に脆いため、これをそのまま内壁用の石膏ボードに採用しても、打ち込む際に石膏ボードを壊してしまう惧れがあり、また抜け止め機能も充分に得ることができないという問題がある。また、クロスが貼り付けられた石膏ボードに回り止め部材を打ち込む際には、事前にクロスに切り込みを入れておく必要があるので、埋設時の作業性に劣るという問題もあった。

特開２００４−３０８８４３号公報 On the other hand, as the above-mentioned anti-rotation means, the anti-rotation member is attached to the embedded portion of the long embedded bolt embedded in the outer wall of the ALC with the tip side portion protruding so as to prevent the embedded bolt from rotating. It has been known. This is made of a flat metal plate exclusively for the outer wall of the ALC, and its construction method is also to make a buried hole in the ALC, inject a resin anchor, insert the buried part of the buried bolt, Even if the embedded portion and the ALC are directly coagulated and bonded, the anti-rotation function and the retaining function can be satisfied at the same time.
However, gypsum board is very fragile compared to ALC, so even if it is used as it is for gypsum board for inner wall, there is a possibility that gypsum board may be broken when it is driven in, and it also has a sufficient retaining function. There is a problem that can not be. In addition, when the anti-rotation member is driven into the gypsum board to which the cloth is pasted, it is necessary to cut the cloth in advance, so that there is a problem that workability at the time of embedding is inferior.

JP 2004-308443 A

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、フック等を取付けする雌ねじが形成されたアンカー本体を樹脂アンカーを用いて壁面に取り付けるようにしたものでありながら、従来屋外のＡＬＣ壁専用の埋設ボルトに備えられていた回り止め部材を応用して、室内の石膏ボード用アンカー本体に利用することが可能となり、石膏ボードの穿設孔にアンカー本体を挿入して、回り止め部材を石膏ボードに打ち込む際、石膏ボードを壊してしまう可能性を著しく低減させることができると共に、クロスが貼り付けられた石膏ボードに回り止め部材を打ち込む際にも、事前にクロスに切り込みを入れる必要もなくなり、確実に回り止め機能を保持することができ、埋設時の作業性にも優れる石膏ボード用アンカーの提供を目的とする。   The present invention was devised to eliminate the above-mentioned problems, and the anchor main body on which a female screw for attaching a hook or the like is formed is attached to a wall surface using a resin anchor. Applying the anti-rotation member that was previously provided in the buried bolts dedicated to outdoor ALC walls, it can be used as an indoor gypsum board anchor body, and the anchor body is inserted into the gypsum board drilling hole. In addition, the possibility of breaking the gypsum board when the detent member is driven into the gypsum board can be significantly reduced, and when the detent member is driven into the gypsum board to which the cloth is pasted, The purpose is to provide an anchor for gypsum board that eliminates the need to make a cut, reliably holds the anti-rotation function, and excels in workability during embedding. To.

上記課題を解決するために本発明の石膏ボード用アンカーは、石膏ボードに埋設される石膏ボード用アンカーであって、内周に雌ネジ部を有し、石膏ボードの穿設孔に挿入されるアンカー本体と、該アンカー本体に一体的に設けられ、アンカー本体を石膏ボードの穿設孔に挿入する際、石膏ボードに打ち込まれてアンカー本体を回り止めする回り止め部材とを備え、該回り止め部材は、打ち込み方向先端部に先鋭状に刃先加工された刃先部を有することを特徴とするものである。   In order to solve the above-mentioned problems, a gypsum board anchor according to the present invention is a gypsum board anchor embedded in a gypsum board, and has a female screw portion on an inner periphery thereof and is inserted into a perforation hole of a gypsum board. An anchor main body, and an anti-rotation member that is provided integrally with the anchor main body and that is driven into the gypsum board and prevents the anchor main body from rotating when the anchor main body is inserted into the hole formed in the gypsum board. The member is characterized in that it has a cutting edge portion that is sharpened at the front end portion in the driving direction.

本発明は、上記のように構成したことにより、フック等を取付けする雌ねじが形成されたアンカー本体を樹脂アンカーを用いて壁面に取り付けるようにしたものでありながら、従来屋外のＡＬＣ壁専用の埋設ボルトに備えられていた回り止め部材を応用して、室内の石膏ボード用アンカー本体に利用することが可能となり、石膏ボードの穿設孔にアンカー本体を挿入して、回り止め部材を石膏ボードに打ち込む際、石膏ボードを壊してしまう可能性を著しく低減させることができると共に、クロスが貼り付けられた石膏ボードに回り止め部材を打ち込む際にも、事前にクロスに切り込みを入れる必要もなくなり、確実に回り止め機能を保持することができ、埋設時の作業性にも優れるものとできる。しかも、埋設完了後に雌ネジ部に取り付けられたフックに重量物が吊持されても、その荷重はアンカー本体とその全長域周縁に注入された樹脂アンカーにより受け止めて、石膏ボードに直接的に負荷が加わることがなく、従来のものに比しより強固な抜け止め機能を得ることができる。
The present invention is configured as described above, so that the anchor main body on which the female screw for attaching the hook or the like is formed is attached to the wall surface using the resin anchor. By applying the locking member provided in the bolt, it can be used for an indoor gypsum board anchor body. The anchor body is inserted into the gypsum board drilling hole, and the locking member is used in the gypsum board. When driving, the possibility of breaking the gypsum board can be significantly reduced, and it is no longer necessary to make a cut in the cloth in advance when the anti-rotation member is driven into the gypsum board to which the cloth is affixed. The anti-rotation function can be maintained, and the workability at the time of embedding can be improved. Moreover, even if a heavy object is suspended on the hook attached to the female thread after completion of burial, the load is received by the anchor main body and the resin anchor injected into the periphery of the entire length area, and loaded directly on the gypsum board. Therefore, it is possible to obtain a stronger retaining function than the conventional one.

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石膏ボード用アンカーを図面に基づいて詳細に説明する。図１は埋設状態を示す石膏ボード用アンカーの使用説明図、図２は石膏ボード用アンカーの正面図、図３は石膏ボード用アンカーの側面図、図４はアンカー本体の平面図、図５は回り止め部材の側面図、図６は樹脂受網の平面図である。   Hereinafter, a gypsum board anchor illustrating an embodiment of the present invention as a preferred embodiment will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram of the use of a gypsum board anchor in an embedded state, FIG. 2 is a front view of the gypsum board anchor, FIG. 3 is a side view of the gypsum board anchor, FIG. 4 is a plan view of the anchor body, and FIG. FIG. 6 is a side view of the rotation preventing member, and FIG. 6 is a plan view of the resin receiving net.

これらの図に示すように、本発明の実施形態に係る石膏ボード用アンカー１は、フック２などを取り付けるために、石膏ボード３に埋設されるものであって、アンカー本体４、回り止め部材５、樹脂受網６、樹脂アンカー７などを備えて構成されている。   As shown in these drawings, a gypsum board anchor 1 according to an embodiment of the present invention is embedded in a gypsum board 3 in order to attach a hook 2 or the like, and includes an anchor body 4 and a detent member 5. The resin receiving net 6 and the resin anchor 7 are provided.

なお、石膏ボード３は、建築物における内壁の下地材として用いられており、その表面には、クロス８などの仕上げ材が貼り付けられている。そして、このような内壁にタオル掛け用や、薄型ＴＶの吊持用のフック２などを取り付ける場合、石膏ボード３に石膏ボード用アンカー１を埋設し、該石膏ボード用アンカー１にフック２の取り付け用ネジ９がねじ込まれる。   The gypsum board 3 is used as a base material for an inner wall in a building, and a finishing material such as a cloth 8 is attached to the surface thereof. When attaching a hook 2 for hanging a towel or holding a thin TV on such an inner wall, a gypsum board anchor 1 is embedded in the gypsum board 3, and the hook 2 is attached to the gypsum board anchor 1. Screw 9 is screwed.

アンカー本体４は、石膏ボード３の穿設孔３ａに挿入されるものであって、外周に凹凸部４ａを有し、内周に雌ネジ部４ｂを有する。外周の凹凸部４ａは、樹脂アンカー７との接着性を高めるためのもので、本実施形態では雄ネジ（ボルト）溝状に形成されるが、ローレット加工などであってもよい。また、内周の雌ネジ部４ｂは、取り付け用ネジ９をねじ込むためのネジ穴である。   The anchor body 4 is inserted into the perforated hole 3a of the gypsum board 3, and has an uneven portion 4a on the outer periphery and a female screw portion 4b on the inner periphery. The outer concavo-convex portion 4a is for enhancing the adhesiveness with the resin anchor 7 and is formed in a male screw (bolt) groove shape in this embodiment, but may be knurled or the like. Further, the inner peripheral female screw portion 4 b is a screw hole for screwing the mounting screw 9.

回り止め部材５は、アンカー本体４に一体的に設けられ、アンカー本体４を石膏ボード３の穿設孔３ａに挿入する際、石膏ボード３に打ち込まれてアンカー本体４を回り止めするものである。そして、本発明に係る石膏ボード用アンカー１の回り止め部材５は、打ち込み方向先端部に先鋭状に刃先加工された刃先部５ａを有する。回り止め部材５の形状や材質に制限はないが、半円形状又は二等辺三角形状の金属プレートとすることが好ましい。この場合には、その頂部が打ち込み方向を向くようにアンカー本体４の外周に溶着される。   The anti-rotation member 5 is provided integrally with the anchor main body 4, and when the anchor main body 4 is inserted into the drilled hole 3 a of the gypsum board 3, it is driven into the gypsum board 3 to prevent the anchor main body 4 from rotating. . And the detent | locking member 5 of the anchor 1 for gypsum boards which concerns on this invention has the blade edge | tip part 5a by which the blade edge | tip process was carried out sharply at the front-end | tip part in the driving direction. Although there is no restriction | limiting in the shape and material of the rotation prevention member 5, It is preferable to set it as a metal plate of a semicircle shape or an isosceles triangle shape. In this case, it is welded to the outer periphery of the anchor body 4 so that its top portion faces the driving direction.

樹脂受網６は、注入された樹脂アンカー７を保持するための袋状の網部材であって、石膏ボード３の穿設孔３ａに挿入される。基端部には、フランジ部６ａが形成され、該フランジ部６ａが穿設孔３ａの周縁部に当接することにより、それ以上の挿入が規制される。そして、石膏ボード３の穿設孔３ａに樹脂受網６を挿入したら、樹脂受網６に樹脂アンカー７を注入すると共に、該樹脂アンカー７中にアンカー本体４を挿入し、さらに、回り止め部材５を石膏ボード３に打ち込んだ後、樹脂アンカー７を硬化させるが、本実施形態の樹脂受網６には、回り止め部材５の刃先部５ａとの接触を避けるための切欠き部６ｂが形成されており、回り止め部材５を叩き込んだ際に変形を回避して、アンカー本体４を含め注入された樹脂アンカー７をしっかりと保持することができる。また、樹脂アンカーとしてウレタンメタル接着系樹脂剤を用いている。   The resin receiving net 6 is a bag-like net member for holding the injected resin anchor 7 and is inserted into the perforated hole 3 a of the gypsum board 3. A flange portion 6a is formed at the base end portion, and the flange portion 6a abuts on the peripheral edge portion of the drilling hole 3a, whereby further insertion is restricted. When the resin receiving net 6 is inserted into the perforated hole 3a of the gypsum board 3, the resin anchor 7 is injected into the resin receiving net 6, and the anchor main body 4 is inserted into the resin anchor 7, and further, a detent member The resin anchor 7 is cured after the 5 is driven into the gypsum board 3, but the resin receiving net 6 of the present embodiment is formed with a notch 6b for avoiding contact with the blade edge 5a of the detent member 5 Thus, deformation can be avoided when the detent member 5 is struck, and the injected resin anchor 7 including the anchor body 4 can be securely held. Further, a urethane metal adhesive resin agent is used as a resin anchor.

次に、石膏ボード用アンカー１の埋設手順について、図７を参照して説明する。   Next, the procedure for burying the gypsum board anchor 1 will be described with reference to FIG.

図７は石膏ボード用アンカーの埋設手順を示す説明図である。この図に示すように、石膏ボード３に石膏ボード用アンカー１を埋設する場合は、まず、石膏ボード３に穿設孔３ａを開ける。次に、穿設孔３ａに樹脂受網６を挿入し、樹脂受網６内に樹脂アンカー７を注入する。このとき、樹脂アンカー７は、樹脂受網６の編み目周縁から石膏ボード３の裏面に充分にはみ出すまで注入する。次に、樹脂アンカー７中にアンカー本体４を挿入すると共に、回り止め部材５を石膏ボード３に打ち込む。このとき、回り止め部材５の刃先部５ａは、自らがクロス８を切断して石膏ボード３に鋭利に刺さる。その後、樹脂アンカー７の硬化を待ち、凝固した後にフック２の取り付けを行う。因みに、フック２の取り付けは、フック２及びワッシャ１０を貫通させた取り付け用ネジ９をアンカー本体４の雌ネジ部４ｂにねじ込むことにより行われる。   FIG. 7 is an explanatory diagram showing a procedure for embedding a gypsum board anchor. As shown in this figure, when the gypsum board anchor 1 is embedded in the gypsum board 3, first, a perforation hole 3 a is opened in the gypsum board 3. Next, the resin receiving net 6 is inserted into the hole 3 a and the resin anchor 7 is injected into the resin receiving net 6. At this time, the resin anchor 7 is injected until it sufficiently protrudes from the periphery of the stitch of the resin receiving net 6 to the back surface of the gypsum board 3. Next, the anchor body 4 is inserted into the resin anchor 7, and the detent member 5 is driven into the gypsum board 3. At this time, the blade edge portion 5 a of the rotation preventing member 5 cuts the cross 8 and pierces the gypsum board 3 sharply. Then, after waiting for the resin anchor 7 to harden and solidify, the hook 2 is attached. Incidentally, the hook 2 is attached by screwing an attachment screw 9 penetrating the hook 2 and the washer 10 into the female screw portion 4 b of the anchor body 4.

叙述の如く構成された本発明の実施の形態において、石膏ボード用アンカー１は、内周に雌ネジ部４ｂを有し、石膏ボード３の穿設孔３ａに挿入されるアンカー本体４と、該アンカー本体４に一体的に設けられ、アンカー本体４を石膏ボード３の穿設孔３ａに挿入する際、石膏ボード３に打ち込まれてアンカー本体４を回り止めする回り止め部材５とを備えるものであるが、回り止め部材５は、打ち込み方向先端部に先鋭状に刃先加工された刃先部５ａを有し、石膏ボード３に打ち込まれる際には、自らがクロス８を切断して石膏ボード３に鋭利に刺さる。従って、回り止め部材５を石膏ボード３に打ち込む際、石膏ボード３を壊してしまう可能性を著しく低減させることができると共に、クロス８が貼り付けられた石膏ボード３に回り止め部材５を打ち込む際、事前にクロス８に切り込みを入れる必要もなくなり、確実に回り止め機能を保持することができ、埋設時の作業性にも優れるものとできる。しかも、アンカー本体４の外周の凹凸部４ａは、従来の如く石膏ボード３の穿設孔３ａに直に螺合させ、ボードの厚さ幅内で荷重を受け止めるものでないため、雌ネジ部４ｂに取り付けられたフック２に薄型ＴＶなどの重量物が吊持されても、その荷重はアンカー本体４とその全長域に注入された樹脂アンカー７により受け止めて、石膏ボード３に直接的に負荷が加わることがなく、従来のものに比しより強固な抜け止め機能を得ることができる。   In the embodiment of the present invention configured as described, the gypsum board anchor 1 has a female screw portion 4b on the inner periphery, and is inserted into the drilled hole 3a of the gypsum board 3; It is provided integrally with the anchor main body 4, and includes an anti-rotation member 5 that is driven into the gypsum board 3 to prevent the anchor main body 4 from rotating when the anchor main body 4 is inserted into the drilled hole 3 a of the gypsum board 3. The anti-rotation member 5 has a cutting edge 5a sharpened at the tip in the driving direction, and when it is driven into the gypsum board 3, the cutting member 5 cuts the cloth 8 into the gypsum board 3 by itself. Pierce sharply. Accordingly, when the anti-rotation member 5 is driven into the gypsum board 3, the possibility of breaking the gypsum board 3 can be remarkably reduced, and when the anti-rotation member 5 is driven into the gypsum board 3 to which the cloth 8 is attached. In addition, it is not necessary to make a cut in the cloth 8 in advance, so that the rotation preventing function can be reliably maintained, and the workability at the time of embedding can be improved. Moreover, the uneven portion 4a on the outer periphery of the anchor body 4 is not screwed directly into the perforated hole 3a of the gypsum board 3 as in the prior art and does not receive the load within the thickness width of the board. Even if a heavy load such as a thin TV is suspended on the attached hook 2, the load is received by the anchor main body 4 and the resin anchor 7 injected into the entire length area thereof, and the load is directly applied to the gypsum board 3. Therefore, it is possible to obtain a stronger retaining function than the conventional one.

また、本実施形態の回り止め部材５は、半円形状（又は二等辺三角形状）の金属プレートからなり、その頂部が打ち込み方向を向くようにアンカー本体４の外周に溶着されるので、石膏ボード３に対する打ち込み抵抗をより低減することができると共に、雌ネジ部４ｂを塞いでしまうなど邪魔になることはない。   The anti-rotation member 5 of the present embodiment is made of a semi-circular (or isosceles triangular) metal plate and is welded to the outer periphery of the anchor body 4 so that the top portion thereof faces the driving direction. 3 can be further reduced, and the internal thread 4b is not obstructed.

また、石膏ボード３の穿設孔３ａに樹脂受網６を挿入すると共に、該樹脂受網６に樹脂アンカー７を注入し、該樹脂アンカー７中にアンカー本体４を挿入するにあたり、樹脂受網６には、回り止め部材５の刃先部５ａとの接触を避けるための切欠き部６ｂが形成されるので、回り止め部材５を叩き込んだ際に、樹脂受網６が回り止め部材５の刃先部５ａとの接触で破損したり変形したりするなどの不都合を回避して、注入された樹脂アンカー７を石膏ボード３の背面側に周辺に行き渡らせた状態で、アンカー本体４をしっかりと保持することができできる。その結果、アンカー本体４と樹脂受網６と樹脂アンカー７とが三位一体となった構成によって、アンカー本体４に加わる負荷が直接穿設孔３ａに加わることが回避され、石膏ボード３に対する抜け止め機能をより強固なものとすることができ、重量物であっても取付けすることができる。   In addition, the resin receiving net 6 is inserted into the hole 3 a of the gypsum board 3, the resin anchor 7 is injected into the resin receiving net 6, and the anchor main body 4 is inserted into the resin anchor 7. 6 is formed with a notch portion 6b for avoiding contact with the blade edge portion 5a of the anti-rotation member 5, so that when the anti-rotation member 5 is struck, the resin receiving net 6 is inserted into the blade edge of the anti-rotation member 5. The anchor body 4 is firmly held in a state where the injected resin anchor 7 is spread around the back side of the gypsum board 3 while avoiding inconvenience such as damage or deformation due to contact with the portion 5a. Can be. As a result, the structure in which the anchor main body 4, the resin receiving net 6 and the resin anchor 7 are integrally formed prevents a load applied to the anchor main body 4 from being directly applied to the drilled hole 3a, and prevents the plaster board 3 from coming off. Can be made stronger, and even heavy objects can be attached.
