物品の固定方法および固定具 技術分野 Method and fixture for fixing articles
本発明は、 物品の固定方法および固定具に関する。 背景技術 The present invention relates to an article fixing method and a fixture. Background art
従来の技術の一例として、 たとえば図 1に示すように、 コンクリート 建造物の屋上に防水シートを張る場合の固定具は次のようにされていた。 A L C板 (軽量発泡コンクリート板) の下地 Aに第 1シート B 1を敷き、 その上に第 2シート B 2を敷く。 そしてこれらのシ一トを固定するため に多数の固定具 Pが用いられる。 まず下穴 Hがドリルであけられ、 次に 図 2に示すような固定具 Pが穴の中に挿入される。 このとき、 あらかじ め円板 Cの中心にねじ軸 P 2を通して、 その後ねじ軸 P 2を外筒 P 1の 中に差し込んだ状態としておく。 そしてこれらの組となったものを前記 穴 Hに挿入する。 そしてねじ軸 P 2をドライバなどでねじ込めば、 外筒 の先端部 P 3が楕円状または卵形状に開く。 これによつて固定具 Pが抜 け止めされた状態となる。 その後にねじ軸の上面に補強用の円板シ一ト Eを敷き、 それを接着などで固定する。 As an example of the conventional technology, as shown in FIG. 1, for example, when fixing a waterproof sheet on the roof of a concrete building, the fixing device is as follows. Spread the first sheet B 1 on the base A of the ALC board (lightweight foam concrete board), and spread the second sheet B 2 on it. A number of fixtures P are used to fix these sheets. First, a pilot hole H is drilled, and then a fixture P as shown in FIG. 2 is inserted into the hole. At this time, the screw shaft P2 is passed through the center of the disk C in advance, and then the screw shaft P2 is inserted into the outer cylinder P1. Then, these pairs are inserted into the holes H. When the screw shaft P2 is screwed in with a screwdriver or the like, the tip P3 of the outer cylinder opens in an elliptical or oval shape. As a result, the fixture P is stopped. Then, lay a reinforcing disk sheet E on the upper surface of the screw shaft, and fix it with adhesive or the like.
しかしながら、 このような従来技術では、 ネジ軸 P 2をねじ込んでい くと、 外筒の先端部 P 3が楕円状または卵形状 (仮想線示) に開くだけ である。 したがって、 弓 Iき上げ力が加わると、 下地の柔軟性とあいまつ て引き抜き易く、 引き抜き強度が強くできない。 そのため極めて多数の 固定具がシー卜の全面にわたり配置されなければならなかった。 またネ ジ軸 P 2のねじ込みにより外筒の先端部 P 3を押し広げて行くので、 押 し広げ力があまり大きなものが得られず、 下地 Aにくい込む部分の量も
少なかった。 従って、 接着剤注入などの作業を要していた。 However, in such a conventional technique, if the screw shaft P2 is not screwed in, the distal end portion P3 of the outer cylinder only opens in an elliptical shape or an oval shape (indicated by a virtual line). Therefore, when the bow I lifting force is applied, it is easy to pull out because of the flexibility of the base, and the pulling strength cannot be increased. Therefore, a large number of fixtures had to be arranged over the entire surface of the sheet. In addition, since the tip end P3 of the outer cylinder is pushed and spread by screwing the screw shaft P2, the pushing force cannot be increased so much, There were few. Therefore, work such as adhesive injection was required.
本発明は上記課題を解決し、 軸の僅かの引き抜きによって抜け止め部 材を強制的に下地層の中にくい込ませるようにし、 引き抜き強度に優れ た物品の固定方法および固定具を提供することを目的とする。 発明の開示 An object of the present invention is to solve the above-mentioned problems, and to provide a method and a fixture for fixing an article having excellent pull-out strength by forcibly inserting a retaining member into an underlayer by slightly pulling out a shaft.

以下に本発明の実施態様を図面に示す一実施例にもとづき説明する。 図 3 , 4 , 5において、 外筒 1は鋼からなり、 円筒状本体 1 aの先端
(下端) に縮径部 l bを持つ。 軸 2は鋼からなり、 該外筒 1の内側に揷 入された棒状本体 2 aの末端 (上端) にドライバ溝付きの皿頭 2 b、 先 端 (下端) 付近に雄ネジ 2 cを持つ。 該軸の先端付近で前記雄ネジ 2 c に雌ネジ部材 3が螺合する。 該雌ネジ部材 3に鋼製の抜け止め部材 4が 別体固着され、 円環部 4 aから該円環部中心を中心とする複数の尖端放 射脚 4 bが末端方に形成されてなる。 Hereinafter, embodiments of the present invention will be described based on an embodiment shown in the drawings. In FIGS. 3, 4, and 5, the outer cylinder 1 is made of steel, and the tip of the cylindrical main body 1a is formed. (Lower end) has reduced diameter part lb. The shaft 2 is made of steel and has a countersunk head 2b with a driver groove at the end (upper end) of the rod-shaped body 2a inserted inside the outer cylinder 1, and a male screw 2c near the tip end (lower end). . A female screw member 3 is screwed into the male screw 2c near the tip of the shaft. A steel retaining member 4 is separately fixed to the female screw member 3, and a plurality of pointed emission legs 4 b centering on the center of the annular portion are formed from the annular portion 4 a at the distal end. .
以上において、 コンクリート建物の屋上に防水シートを A L C下地材 の表面に敷いて固定する場合を説明する。 下地材 Aに第 1、 第 2シート B l, B 2を敷き、 次にドリルで下穴 Hをあける。 また固定具の軸 2に 押え板たる円板 Cの中心を通した状態で軸 2を外筒 1に挿入し、 抜け止 め部材 4を固定した雌ねじ部材 3に軸の先端部の雄ネジ 2 cをねじ込む。 このとき外筒の縮径部 1 bに抜け止め部材の放射脚部 4 bが閉じた状態 で接触している。 この状態で下穴 Hに挿入する。 このとき、 外筒の末端 がシート B 2の上面にほぼ臨んだ状態で、 軸 2の先端と下穴 Hの底との 間には、 軸 2のねじ込み分だけあいている。 The case where the waterproof sheet is laid on the surface of the ALC base material and fixed on the roof of a concrete building is explained above. Lay the first and second sheets Bl, B2 on the base material A, and then drill a pilot hole H with a drill. Insert the shaft 2 into the outer cylinder 1 with the center of the disc C as the holding plate passing through the shaft 2 of the fixture, and insert the male screw 2 at the tip of the shaft into the female screw member 3 to which the retaining member 4 is fixed. Screw in c. At this time, the radial leg portion 4b of the retaining member is in contact with the reduced diameter portion 1b of the outer cylinder in a closed state. In this state, insert into prepared hole H. At this time, with the end of the outer cylinder almost facing the upper surface of the sheet B 2, there is a gap between the tip of the shaft 2 and the bottom of the pilot hole H by the amount of the screw of the shaft 2.
次に突出している軸の頭 2 bの下にバール Dの二股部を揷入し、 バー ル支点部 D 0で円板 Cを介して外筒 1の末端を押さえ付ける。 そして、 バール Dの柄を先端方に押し下げると、 外筒 1はそのままの状態で、 軸 2は強力に末端方に引き上げられる。 このとき図 5のように、 抜け止め 部材 4は強制的に押し上げられて、 放射脚部 4 bは外筒縮径部 l bに案 内されて斜め末端方に放射状に開き、 半径方向の外側へ下地材 Aの層内 にくい込んでいく。 このとき、 放射脚部は尖った先端から順に下地層内 に進入するので、 層を不必要に破壊することなく、 層に突き刺さる。 次に軸 2を先端方にねじ込んでいくと、 雌ネジ部材 3は固定された状 態であるので、 軸 2のみが先端方に進み、 軸頭 2 bが円板 Cの上面を押 し付けてシート B 2を固定する。 次いで補強円板シート Eを軸頭 2わの
上を覆つて接着剤で張り付けられる。 Next, insert the bifurcated portion of the crowbar D under the protruding shaft head 2b, and press the end of the outer cylinder 1 via the disk C at the crowbar fulcrum portion D0. Then, when the handle of the burl D is pushed down toward the tip, the outer cylinder 1 is left as it is, and the shaft 2 is pulled up strongly toward the end. At this time, the retaining member 4 is forcibly pushed up as shown in FIG. In the layer of base material A At this time, the radiating legs penetrate into the underlayer in order from the sharp tip, and penetrate into the layer without unnecessarily destroying the layer. Next, when the shaft 2 is screwed into the tip, the female screw member 3 is in a fixed state, so only the shaft 2 advances toward the tip, and the shaft head 2b presses the upper surface of the disk C. To secure sheet B2. Next, insert the reinforcing disk sheet E into the shaft head 2 It is glued over the top.
次に本発明の他の実施態様を図面に示す一実施例にもとづき説明する。 図 6において、 軸 2は鋼からなり、 該外筒 1の内側に挿入された棒状本 体 2 aの末端付近に雄ネジ 2 c、 先端に六角頭 2 bを持つ。 該軸の末端 付近で前記雄ネジ 2 cに雌ネジ部材 3が螺台する。 軸の頭 2 bに抜け止 め部材 4の円環部 4 aが塑性変形してが嵌合固定される。 その他の部分 は前記図 3, 4, 5のものと同様である。 Next, another embodiment of the present invention will be described based on one embodiment shown in the drawings. In FIG. 6, the shaft 2 is made of steel and has a male screw 2c near the end of a rod-shaped body 2a inserted inside the outer cylinder 1 and a hexagonal head 2b at the tip. A female screw member 3 is screwed on the male screw 2c near the end of the shaft. The annular portion 4a of the retaining member 4 is plastically deformed to the stopper 2b on the shaft head 2b, and is fitted and fixed. Other parts are the same as those shown in FIGS.
そして、 外筒 1の末端から突出した雄ネジ部 2 cに円板 Cの中心を通 した状態で、 雄ネジ部 2 cに雌ネジ部材 3をねじ込む。 次に突出してい る雌ネジ部材 3の下にバール Dの二股部を挿入し、 バールの柄を先端方 に押し下げると、 軸 2は強力に末端方に引き上げられる。 そして前記と 同様に、 放射脚部 4 bは下地材 Aの層内にくい込んでいく。 Then, the female screw member 3 is screwed into the male screw portion 2c with the center of the disk C passing through the male screw portion 2c protruding from the end of the outer cylinder 1. Next, when the bifurcated portion of the crowbar D is inserted under the protruding female screw member 3 and the handle of the crowbar is pushed down toward the distal end, the shaft 2 is strongly pulled up toward the distal end. In the same manner as described above, the radiating leg 4b penetrates into the layer of the base material A.
次に雌ネジ部材 3を先端方にねじ込んでいくと、 軸 2は固定された状 態であるので、 雌ネジ部材 3のみが先端方に進み、 円板 Cの上面を押し 付けてシート B 2を固定する。 次いで、 軸 2の突出した部分を切断し、 補強円板シート Eを軸 2の末端を覆って接着剤で張り付けられる。 邪魔 にならない場所では、 軸 2を切断せず、 突出したままとしておく。 Next, when the female screw member 3 is screwed toward the distal end, since the shaft 2 is in a fixed state, only the female screw member 3 advances toward the distal end, and the upper surface of the disc C is pressed against the sheet B 2. Is fixed. Next, the protruding portion of the shaft 2 is cut, and the reinforcing disk sheet E is attached to the end of the shaft 2 with an adhesive. In a place where it does not get in the way, keep the shaft 2 protruding without cutting it.
更に強力な引き抜き強度が要求される個所では、 下地の下穴内に接着 剤を注入する。 この場合、 注入器による注入作業は手間を要するので、 本発明では注入作業時間を大幅に短縮させたものも以下に提供する。 即ち、 図 4で仮想線示のごとく、 前記外筒 1の中途部に接着剤進入孔 In places where even higher pull-out strength is required, the adhesive is injected into the pilot hole in the base. In this case, since the injection operation using the injector requires time and effort, the present invention also provides a device in which the injection operation time is greatly reduced. That is, as shown by the phantom line in FIG.
1 dが設けられ、 該接着剤進入孔より先端側および前記抜け止め部を覆つ て、 ポリエチレン、 塩化ビニル等のプラスチックフィルム袋 6がかぶせ られる。 そして、 これらが熱湯中に浸され、 袋が加熱収縮して付着され る。 また、 この袋の付着に先立って、 前記抜け止め部材の円環部 4 aの 外周にゴム, プラスチック等の伸縮性シールリング 7が嵌められる。
作業にあたり、 軸 2を外筒 1から抜き出して円板 Cを挿入し、 次に軸 2を外筒 1に挿入し、 雌ネジ部材 3にねじ込む。 この状態の袋付きのも のを接着剤 (水硬セメント類やエポキシ樹脂など) 槽の中に浸漬し、 前 記接着剤孔から接着剤を外筒 1内に進入させて溜め、 その後に槽から取 り出す。 1d is provided, and a plastic film bag 6 of polyethylene, vinyl chloride, or the like is covered so as to cover the tip end side from the adhesive entry hole and the retaining portion. Then, these are immersed in hot water, and the bags are heated and shrunk and adhered. Prior to the attachment of the bag, an elastic seal ring 7 made of rubber, plastic, or the like is fitted around the outer periphery of the annular portion 4a of the retaining member. For the operation, pull out the shaft 2 from the outer cylinder 1 and insert the disk C, then insert the shaft 2 into the outer cylinder 1 and screw it into the female screw member 3. In this state, the bag with the bag is immersed in an adhesive (hydraulic cement, epoxy resin, etc.) tank, and the adhesive is allowed to enter the outer cylinder 1 through the adhesive hole and stored. Remove from
次に、 これら組付けられたものを被固定物たるシート B 1, B 2およ び下地材 Aの下穴 Hに挿入する。 次に、 前記と同様に、軸 2を引き上げ、 前記抜け止め部を前記下地材の層内にくい込ませる。 このとき、 前記袋 6を破って接着剤が流出し、 抜け止め部の周辺組織に速やかに浸透する。 シールリング 7のため、 接着剤が下穴 Hの先端付近の空洞に逃れるのが 阻止できる。 次に前記軸 2を先端方にねじ込む。 このように、 抜け止め 部とその周辺組織が接着剤により一体固化し、 引き抜き強度が大幅に増 加する。 Next, these assembled parts are inserted into the prepared holes B and B2 of the fixed object and the prepared hole H of the base material A. Next, in the same manner as described above, the shaft 2 is pulled up, and the retaining portion is inserted into the layer of the base material. At this time, the adhesive breaks out of the bag 6, and the adhesive quickly permeates into the tissue around the retaining portion. The seal ring 7 prevents the adhesive from escaping into the cavity near the tip of the pilot hole H. Next, the shaft 2 is screwed toward the tip. Thus, the retaining portion and the surrounding tissue are solidified by the adhesive, and the pull-out strength is greatly increased.
なお、 前記外筒 1に接着剤進入孔を設けずに、 その末端 (上端) より 先端 (下端) 側および前記抜け止め部材 4を覆って、 袋 6を付着すれば、 外筒 1の末端近くまで、 大量に接着剤を溜めることができる。 また、 抜 け止め部材 4の直上付近の外筒 1に接着剤流出孔 1 c (図 4 ) を設けれ ば、 抜け止め部材の拡張による袋の破れや剥離により、 この孔から接着 剤が流れ出て、 抜け止め部材より上方の下地にも浸透して固化し、 更に 抜け止め強度が増す。 In addition, if the outer cylinder 1 is not provided with an adhesive entrance hole, and covers the tip (lower) side from the end (upper end) and the retaining member 4 and the bag 6 is adhered, the end of the outer cylinder 1 is near. Until a large amount of adhesive can be stored. Also, if an adhesive outflow hole 1c (Fig. 4) is provided in the outer cylinder 1 immediately above the retaining member 4, the adhesive will flow out of this hole due to the breakage or peeling of the bag due to the expansion of the retaining member. As a result, it penetrates into the substrate above the retaining member and solidifies, further increasing the retaining strength.
図 7は他の実施態様を示し、 前記下穴 Hをあけないで、 固定具自体を ハンマなどで打込むようにしたものである。 即ち、 軸 2の先端部に尖端 キャップ 5が嵌合される。 このキャップは下側にテーパ面 5 aを持つ鋼 製の逆円錐状部材からなる。 この態様のものは、 比較的細い外筒のもの で、 下地層も割れが生じないような個所に使用される。 FIG. 7 shows another embodiment, in which the fixture itself is driven by a hammer or the like without drilling the pilot hole H. That is, the pointed cap 5 is fitted to the tip of the shaft 2. This cap is made of a steel inverted conical member having a tapered surface 5a on the lower side. This embodiment has a relatively thin outer cylinder and is used in a place where the underlayer does not crack.
本発明では、 軸 2を通して外筒 1の末端の被固定物と、 外筒直径より
相当大きく (例えば 2倍以上) 広がった抜け止め部材との間に、 下地 (例えば、 軽量発泡コンクリート) を挟み込むようなかたちで固定する。 従って、 抜け止め部材 4から軸 2を挟んで例えば 4 5度一 4 5度合計 9 0度より上方の部分 (図 2の仮想線示のような、 抜け止め部材 4を頂点 とする逆円錐体) の、 この組織が破壊するに等しい引き抜き強度を持つ。 または逆に、 抜け止め部材 4が破断する剪断強度に等しい引き抜き強度 を持つ。 一 In the present invention, the fixed object at the end of the outer cylinder 1 through the shaft 2 and the outer cylinder diameter Fix the base (for example, lightweight foam concrete) between the considerably large (for example, twice or more) spread retaining member. Therefore, for example, a portion above the total of 90 degrees between 45 ° and 45 ° across the shaft 2 from the retaining member 4 (an inverted cone whose vertex is the retaining member 4 as shown by the phantom line in FIG. 2) ) This tissue has a pull-out strength equal to breaking. Or, conversely, the pullout strength is equal to the shear strength at which the retaining member 4 breaks. one
従来工法の抜け止め部 (拡張部) は引き抜き方向に流線形に変形する ので、 強力な引き抜き外力が加わると、 上方組織を拡張圧縮しながら抜 け出してしまう。 また、 防水シート固定化のために使用した場合は、 施 ェ後 1 0〜2 0年の長期間にわたり、 風の負圧による数十万回を越える 大小さまざまな引き抜き外力が抜け止め部を保持する軸に加わる。 その 度に抜け止め部の周辺に微振動が生じ、 少しずつ周辺組織が破壊される 恐れがある。 本発明では長期間の微振動または引き抜き外力にも全く、 または、 ほとんど影響を受けないと予想される。 The retaining part (expansion part) of the conventional method deforms in a streamlined manner in the pull-out direction, so if a strong pull-out external force is applied, the upper tissue will be pulled out while expanding and compressing. In addition, when used for fixing the waterproof sheet, the pull-out external force of hundreds of thousands of times due to the negative pressure of the wind holds the retaining part for a long period of 10 to 20 years after the application. To join the axis. Each time, micro-vibration occurs around the retaining part, and the surrounding tissue may be destroyed little by little. It is anticipated that the present invention will be completely or almost unaffected by long-term micro-vibration or external pull-out force.
