Description
この発明は、デッキ材と称されているような長尺の床材を下地材に対して固定する床材の固定具、更に詳しくは、床材を下地材に固定する作業の施工性がよく、並列配置した床材の途中に位置する床材の交換が可能となり、しかも、固定した床材の横ずれ発生を確実に防ぐことができる固定具に関する。 The present invention is a flooring fixture for fixing a long flooring material called a decking material to a base material, and more specifically, the workability of fixing the flooring material to the base material is good. Further, the present invention relates to a fixture that enables replacement of a floor material located in the middle of the floor materials arranged in parallel, and can reliably prevent the occurrence of lateral displacement of the fixed floor material.
建物等に付設されるデッキを構築するには、長さ方向の両側に凹溝が設けられた床材と、この床材を根太や大引き等の下地材に対して固定するための固定具と、この固定具から下地材にねじ込むビスとを用い、下地材の上に多数枚の床材を並列状態の配置で並べ、隣接する床材の凹溝に亘って嵌め合わせた固定具を、この固定具から下地材に向けてねじ込むビスによって固定し、これにより、下地材に対して床材を固定するものである。 In order to build a deck attached to a building, etc., a flooring provided with concave grooves on both sides in the length direction, and a fixture for fixing the flooring to a base material such as joist or large pulling And a screw screwed into the base material from this fixing tool, a plurality of floor materials arranged in a parallel state on the base material, and a fixing tool fitted over the concave grooves of the adjacent floor materials, The floor is fixed to the base material by fixing with a screw screwed from the fixing tool toward the base material.
従来、前記のような床材の固定に用いられる固定具には、下地材と床材のそれぞれにビス止めすることにより下地材に対して床材を固定する方式と、下地材だけにビス止めすることにより下地材に対して床材を固定する方式がある。 Conventionally, the fixing tool used for fixing the flooring material as described above has a method of fixing the flooring material to the base material by screwing the base material and the floor material, and screwing only to the base material. By doing so, there is a method of fixing the flooring to the base material.
前者の下地材と床材のそれぞれにビス止めする従来の固定具１は、図７に示すように、下板２の上面中央に縦板３を設け、この縦板３の上端に両側に張り出す上板４を設け、前記下板２の一方側縁に固定板５を連成し、縦板３を挟む両側を背中合わせの溝形部にした断面形状を有し、前記縦板３と固定板５にビス挿通孔６、７を設けた構造になっている。 As shown in FIG. 7, the conventional fixture 1 that is screwed to each of the former base material and floor material is provided with a vertical plate 3 in the center of the upper surface of the lower plate 2, and the upper end of the vertical plate 3 is stretched on both sides. An upper plate 4 is provided, a fixing plate 5 is coupled to one side edge of the lower plate 2, and has a cross-sectional shape in which both sides sandwiching the vertical plate 3 are back-to-back groove portions, and is fixed to the vertical plate 3. The plate 5 is provided with screw insertion holes 6 and 7.
下地材ａ上において、この下地材ａに載置した固定具１の上板４と床材ｂの凹溝ｃを嵌め込むことで一方の溝形部に床材ｂの下側突部ｄを収め、縦板２のビス挿通孔６から床材ｂにビス８をねじ込むことで固定具１と床材ｂを固定し、次に、固定板５のビス挿通孔７から下地材ａにビス９をねじ込んで固定具１を下地材ａに固定し、これにより、床材ｂの一方側部を下地材ａに固定する。 On the base material a, by fitting the upper plate 4 of the fixture 1 placed on the base material a and the concave groove c of the floor material b, the lower protrusion d of the floor material b is formed in one groove-shaped portion. The fixing tool 1 and the floor material b are fixed by screwing screws 8 into the floor material b from the screw insertion holes 6 of the vertical plate 2, and then screws 9 to the base material a from the screw insertion holes 7 of the fixing plate 5. To fix the fixture 1 to the base material a, thereby fixing one side of the floor material b to the base material a.
この後、前記床材ｂの横に新たな床材ｂを並列状に配置し、その他方側縁における凹溝ｃを固定具１の上板４に嵌め込むことで他方の溝形部に床材ｂの下側突部ｄを収め、新たな床材ｂの他方側を下地材ａに固定化し、この新たな床材ｂの一方側部を前記と同じように固定具１とビス８、９を用いて下地材ａに固定し、このような床材ｂの並列配置と下地材ａへの固定作業を繰り返すことにより、多数枚の並列する床材ｂでデッキを構成する。 After that, a new floor material b is arranged in parallel next to the floor material b, and a concave groove c on the other side edge is fitted into the upper plate 4 of the fixture 1 so that the other groove-shaped portion has a floor. The lower projection d of the material b is accommodated, the other side of the new floor material b is fixed to the base material a, and the one side part of the new floor material b is fixed to the fixture 1 and the screw 8 in the same manner as described above. 9 is fixed to the base material a, and the deck is constituted by a large number of parallel floor materials b by repeating the parallel arrangement of the floor material b and the fixing operation to the base material a.
前記のような下地材ａと床材ｂのそれぞれにビス止めする固定具１は、固定具１と床材ｂを水平のビス８で結合するため、床材ｂの伸縮による幅方向の横ずれ防止が得られるが、二本のビス８と９のねじ込み作業が必要になり、固定作業に時間と手間がかかることになり、また、床材ｂと固定するビス８は横から水平にねじ込まなければならないので、ねじ込み作業が行いにくいという問題がある。 Since the fixture 1 for fixing screws to the base material a and the floor material b as described above connects the fixture 1 and the floor material b with the horizontal screws 8, it prevents the lateral displacement in the width direction due to the expansion and contraction of the floor material b. However, the screwing work of the two screws 8 and 9 is necessary, and it takes time and labor for the fixing work, and the screw 8 to fix the floor material b must be screwed horizontally from the side. Therefore, there is a problem that it is difficult to perform the screwing operation.
また、固定具１と床材ｂを結合するビス８及び固定具１を下地材ａに固定するビス９は、床材ｂで覆われてしまう構造であるため、デッキを構成した状態で、途中にある一枚の床材だけを取り外すことができないという致命的な欠点があり、途中の床材が損傷した場合は端の床材から順に取外さなければならず、床材の取換えに多くの手間と時間がかかるという問題がある。 Further, the screw 8 for connecting the fixture 1 and the floor material b and the screw 9 for fixing the fixture 1 to the base material a are structured to be covered with the floor material b. There is a fatal defect that it is not possible to remove only one flooring in the case, and if the flooring in the middle is damaged, it must be removed in order from the flooring at the end, which is often used to replace flooring The problem is that it takes time and effort.
次に、後者の下地材だけにビス止めする固定具は、中央にビス孔を有する板状金具本体の両側に押圧片を設け、前記金具本体の下面で両側に一対の脚部を設けた構造を有している（例えば、特許文献１参照）。 Next, the latter fixing tool only to the base material has a structure in which a pressing piece is provided on both sides of a plate-shaped metal fitting body having a screw hole in the center, and a pair of legs are provided on both sides on the lower surface of the metal fitting body. (For example, refer to Patent Document 1).
この固定具でデッキを構成するには、床材を載置した下地材の上面に固定具を位置させ、一方押圧片を床材の凹溝に嵌め込んで脚部を下地材の上に接地させた仮置き状態とし、次に、板状金具本体のビス孔に予めセットしておいた垂直のビスを下地材にねじ込み、固定具を下地材に固定すると同時に一方押圧片で床材を押圧固定する。 To configure the deck with this fixture, place the fixture on the top surface of the base material on which the floor material is placed, while the pressing piece is fitted in the groove in the floor material and the legs are grounded on the base material. Next, screw the vertical screw set in advance in the screw hole of the plate-shaped bracket body into the base material to fix the fixture to the base material and simultaneously press the floor with one pressing piece Fix it.
この後、前記床材の横に新たな床材を並列状に配置し、その他方側面における凹溝下部を固定具の他方押圧片と下地材の間に嵌め込むことで、新たな床材の他方側を下地材に固定化し、この新たな床材の一方側部を前記と同じように固定具とビスを用いて下地材に固定し、このような床材の並列配置と下地材への固定作業を繰り返すことにより、多数枚の並列する床材でデッキを構成する。 After that, a new flooring is arranged in parallel next to the flooring, and the concave groove lower part on the other side surface is fitted between the other pressing piece of the fixture and the base material, so that the new flooring The other side is fixed to the base material, and one side portion of the new floor material is fixed to the base material using a fixing tool and a screw in the same manner as described above. By repeating the fixing work, a deck is composed of a large number of parallel flooring materials.
このような固定具は、一本のビスにより上からのねじ込みによって固定できるので、固定作業が簡単であると共に、デッキの構成状態で床材間の隙間から工具を挿入してビスを緩め、この工具で固定具を凹溝の長さ方向に沿って移動させ、凹溝の端部から取り出すことができるので、途中にある一枚の床材に損傷が生じた場合、この一枚の床材だけを取り外して取替えることができるという利点がある。 Since such a fixture can be fixed by screwing from above with a single screw, the fixing work is easy, and a screw is loosened by inserting a tool through the gap between floor materials in the deck configuration state. The fixture can be moved along the length of the groove with a tool and removed from the end of the groove, so if one piece of flooring in the middle is damaged, this piece of flooring There is an advantage that only can be removed and replaced.
ところで、床材の両側面において、凹溝を設ける位置や幅により、この凹溝の下面と床材の底面間に形成される下側突部の高さ寸法は、メーカーや品番によって異なったり製品での誤差が生じている場合がある。 By the way, depending on the manufacturer and product number, the height dimension of the lower protrusion formed between the lower surface of the groove and the bottom surface of the floor material depends on the position and width of the groove on both sides of the floor material. There may be an error in.
これに対して、前記した固定具はアルミを用いた押し出し成形によって形成されており、下地材の上に載る脚部の下端から押圧片の下面までの寸法が一定化された構造になっている。 On the other hand, the fixture described above is formed by extrusion molding using aluminum, and has a structure in which the dimension from the lower end of the leg portion placed on the base material to the lower surface of the pressing piece is made constant. .
このため、固定具の脚部の下端から押圧片の下面までの寸法と床材の下側突部の高さ寸法が一致する場合、下地材上に固定具を水平に仮設置することができ、ビスのねじ込み作業が支障なく行えることになるが、床材の下側突部を押さえ込んで固定することができず、床材の幅方向に沿う横ずれ防止機能がまったくなく、また、固定具の脚部の下端から押圧片の下面までの寸法と床材の下側突部の高さ寸法が不一致の場合、下側突部の高さ寸法が高いと仮設置した固定具は床材に対して外側に傾斜し、このため、ビスが傾斜することで上からのねじ込み作業が行いにくいだけでなく、仮置きしたときに固定具が外側に倒れてしまい、固定具が使用できない事態が生じることになる。 For this reason, when the dimension from the lower end of the leg of the fixture to the lower surface of the pressing piece matches the height of the lower projection of the flooring, the fixture can be temporarily placed horizontally on the base material. The screw can be screwed in without any trouble, but the bottom protrusion of the flooring cannot be pressed down and fixed, and there is no function to prevent lateral displacement along the width of the flooring. If the dimension from the lower end of the leg part to the lower surface of the pressing piece and the height of the lower protrusion of the flooring do not match, if the height of the lower protrusion is high, the temporarily installed fixture will Therefore, not only is it difficult to screw in from the top due to the tilting of the screw, but the fixture may fall outside when temporarily placed, and the fixture may not be usable. become.
更に、固定具の脚部の下端から押圧片の下面までの寸法に対して下側突部の高さ寸法が低い場合、仮設置した固定具の押圧片と下側突部の間に隙間が生じ、ビスをねじ込んで固定具を下地材に固定しても、押圧片は下側突部を押さえ込むことができず、結果として床材を下地材に対してガタツキのないよう固定することができないことになる。 Furthermore, when the height of the lower projection is lower than the dimension from the lower end of the leg of the fixture to the lower surface of the press piece, there is a gap between the press piece of the temporarily installed fixture and the lower projection. Even if the screw is screwed in and the fixture is fixed to the base material, the pressing piece cannot press down the lower protrusion, and as a result, the floor material cannot be fixed to the base material without rattling. It will be.
このように、従来の固定具は、固定具の脚部の下端から押圧片の下面までの寸法と床材の下側突部の高さ寸法が一致する場合しか使用することができず、その使用可能な範囲が制約を受けることになる。 As described above, the conventional fixture can be used only when the dimension from the lower end of the leg of the fixture to the lower surface of the pressing piece matches the height of the lower protrusion of the flooring. The usable range is restricted.
そこで、この発明の課題は、床材の下側突部の高さ寸法が異なる場合でも倒れることのないよう安定よく仮設置することができ、しかも、確実に下側突部を押さえ込んで下地材に床材を固定することができる床材の固定具を提供することにある。 Therefore, the problem of the present invention is that it can be temporarily and stably installed so that it does not fall down even when the height of the lower protrusion of the flooring is different, and the lower protrusion is reliably pressed down to provide a base material. An object of the present invention is to provide a flooring fixture that can fix a flooring.
前記のような課題を解決するため、この発明は、側面に長さ方向の凹溝が設けられた床材を下地材の上に並べ、隣接する床材の凹溝に亘って嵌り合う状態で、前記床材を下地材に固定する固定具であって、中間位置にビス挿通孔が設けられた天板と、前記天板の両側に張り出すよう設けられ、前記隣接する床材の凹溝内にそれぞれ嵌る押圧部とで金具本体が形成され、この金具本体における前記天板の両端に一対の下向き支持脚を設け、前記金具本体と支持脚は、一枚の金属板から一体に形成され、前記一対の支持脚は、天板の両端から下部広がりの傾斜状配置となるように折り曲げて設けられ、下端が下地材に当接して自立することで前記金具本体の押圧部が床材の凹溝内に嵌る高さ位置に保持することができる長さを有し、前記金具本体を上部から押し下げたときに開脚可能な弾性を有し、その下端に前記下地材に対する水平方向の接地片が設けられているようにしたものである。 In order to solve the problems as described above, the present invention is arranged in such a state that floor materials having side grooves provided in the length direction are arranged on the base material and fitted over the groove grooves of the adjacent floor materials. A fixing device for fixing the floor material to the base material, wherein the top plate is provided with screw insertion holes at an intermediate position, and is provided so as to project on both sides of the top plate. A metal fitting body is formed by the respective pressing portions that fit inside, and a pair of downward support legs are provided at both ends of the top plate of the metal fitting body, and the metal fitting body and the support legs are integrally formed from a single metal plate. The pair of support legs are bent and provided so as to have an inclined arrangement extending from both ends of the top plate, and the lower end is in contact with the base material so that the pressing portion of the metal fitting body is made of the floor material. The metal fitting body has a length that can be held at a height position that fits in the groove. It has open leg resilient when depressed from the top, in which as a horizontal ground pieces are provided for the base member at its lower end.
前記金具本体における天板の下面に、この金具本体の両側幅方向に対する姿勢補助部材が固定され、この姿勢補助部材は、合成樹脂を用い、天板の下面から下方に向けて延び、前記天板のビス挿通孔と同軸心の配置となる筒軸と、前記筒軸の下端部で金具本体の幅方向に沿う両側の位置に、この筒軸の下端から下部広がりの傾斜状配置となるよう設けられ、前記金具本体を上部から押し下げたときに開脚可能となる一対の補助脚と、両補助脚の下端に外方へ屈曲するよう設けた接地片で形成され、前記筒軸は、前記支持脚よりも短い上下長さを有し、前記補助脚は、下端が前記支持脚の下端と同じ高さ位置かそれよりも下方に位置している構造とすることができる。 At the bottom surface of the top plate of the metal fitting body, a posture assisting member for the both sides width direction of the metal fitting main body is fixed. The posture auxiliary member uses synthetic resin and extends downward from the bottom surface of the top plate. A cylindrical shaft that is arranged coaxially with the screw insertion hole of the screw shaft, and provided at a position on both sides along the width direction of the metal fitting body at the lower end portion of the cylindrical shaft so as to have an inclined arrangement extending downward from the lower end of the cylindrical shaft A pair of auxiliary legs that can be opened when the metal fitting body is pushed down from above, and a grounding piece that is bent outwardly at the lower ends of both auxiliary legs, and the cylindrical shaft is supported by the support shaft The auxiliary leg may have a vertical length shorter than that of the leg, and the auxiliary leg may have a lower end located at the same height as or below the lower end of the support leg.
ここで、金具本体における天板は、床材の長さ方向に沿って長い長方形となり、その両側に設けた押圧部は天板よりも長く、天板の両端から長さ方向に沿って突出し、前記天板の両端に設けた支持脚は両押圧部間を下向きに屈曲し、この支持脚の根元部分は、金属板の弾性を生かし、支持脚の開脚を容易にするための細幅部に形成されている。 Here, the top plate in the metal fitting body is a rectangle that is long along the length direction of the flooring, and the pressing portions provided on both sides of the top plate are longer than the top plate and protrude along the length direction from both ends of the top plate, The support legs provided at both ends of the top plate are bent downward between the pressing parts, and the base part of the support legs makes use of the elasticity of the metal plate to make the support legs easy to open. Is formed.
また、姿勢補助部材の筒軸は、上下軸線に沿ってビス孔が貫通する角形の筒状に形成され、この筒軸の上面でビス孔を挟む両側の位置に設けた突起を、金具本体における天板の対応する位置に設けた小孔に嵌め込むことにより、金具本体に対する姿勢補助部材の取り付けを行い、この取り付けにより、天板の下面に筒軸の上端から腕板の上面が重なり、前記腕板の先端に設けた二又部が支持脚の根元細幅部分外嵌するとにより、金具本体の長さ方向及び幅方向に対する姿勢補助部材の固定が同時に得られるようになっている。 Further, the cylinder shaft of the posture assisting member is formed in a rectangular cylinder shape through which the screw hole penetrates along the vertical axis, and protrusions provided on both sides sandwiching the screw hole on the upper surface of the cylinder shaft are formed on the metal fitting body. By fitting into a small hole provided at a corresponding position of the top plate, the posture auxiliary member is attached to the metal fitting body, and by this attachment, the upper surface of the arm plate overlaps the lower surface of the top plate from the upper end of the tube shaft, Fixing of the posture assisting member in the length direction and width direction of the metal fitting body can be obtained simultaneously by fitting the bifurcated portion provided at the tip of the arm plate to the base narrow width portion of the support leg.
この発明の固定具は、長さ方向の両端に支持脚と幅方向の両側に補助脚を設けることにより、下地材の上に配置したとき支持脚と補助脚によって、長さ方向と幅方向の何れにも安定した自立状態が保持され、例えば、床材に設けた凹溝の下側突部の高さ寸法が規定より高いような場合、凹溝内に押圧部を嵌め込むことで固定具は外側下がりに傾斜することになるが、この傾斜による倒れこみを補助脚の接地によって防ぐことができ、仮配置時に固定具が倒れることがないので、上部からのビスのねじ込み作業が支障なく行え、床材の固定状態がえられることになる。 The fixture of the present invention is provided with support legs on both ends in the length direction and auxiliary legs on both sides in the width direction, so that when placed on the base material, the fixing legs in the length direction and the width direction are arranged by the support legs and the auxiliary legs. In any case, a stable self-standing state is maintained. For example, when the height dimension of the lower protrusion of the concave groove provided in the flooring is higher than specified, the fixing tool can be fitted by inserting the pressing portion into the concave groove. Can be prevented from falling down by the grounding of the auxiliary leg, and the fixing tool does not fall down during temporary placement, so screwing work from the top can be done without any trouble. The fixed state of the flooring can be obtained.
また、床材に設けた凹溝の下側突部の高さ寸法が規定より低いような場合、凹溝内に押圧部を嵌め込むことで固定具は、支持脚と補助脚によって自立した仮配置状態が得られ、上部からのビスのねじ込みにより金具本体が押し下げられると、支持脚と補助脚が開脚することで押圧部が凹溝の下側突部を押圧し、床材の固定状態がえられることになる。 In addition, when the height dimension of the lower protrusion of the concave groove provided on the flooring is lower than specified, the fixture can be temporarily supported by the supporting leg and the auxiliary leg by fitting the pressing portion into the concave groove. When the mounting state is obtained and the bracket body is pushed down by screwing the screw from the top, the support leg and the auxiliary leg are opened, the pressing part presses the lower protrusion of the concave groove, and the floor material is fixed It will be obtained.
請求項１の発明によると、天板とその両側に張り出すよう設けられた押圧部とで形成された金具本体の両端に一対の下向き支持脚を設け、この支持脚は、前記金具本体の押圧部が床材の凹溝内に嵌る高さ位置に保持することができる長さを有し、前記金具本体を上部から押し下げたときに開脚可能な弾性を有し、その下端に水平方向の接地片が設けられているので、ビスのねじ込みによる床材の固定時に、支持脚の開脚により押圧部を下降させることができる構造となり、凹溝の下側突部の高さ寸法に変動があっても、床材を下地材に対してガタツキのないよう固定することができ、下側突部の高さ寸法に対して、単一の構造で広範に対応することができると共に、金具本体は、下地材の上面に載せ置いた状態で床材を固定できるので、下地材の幅条件に制約を受けることなく単一の構造で床材を固定できる。 According to the first aspect of the present invention, the pair of downward support legs are provided at both ends of the metal fitting body formed by the top plate and the pressing portions provided so as to project on both sides thereof. It has a length that can be held at a height position that fits into the groove of the flooring material, and has elasticity that can be opened when the metal fitting body is pushed down from above , with a horizontal direction at its lower end. Since the grounding piece is provided, when the flooring is fixed by screwing in the screw, the pressing part can be lowered by the opening leg of the support leg, and the height dimension of the lower protrusion of the concave groove varies. Even if there is, the flooring can be fixed to the base material without rattling, and the height of the lower projection can be widely accommodated with a single structure, and the bracket body Since the flooring can be fixed in a state where it is placed on the top surface of the base material, The flooring can be fixed in a single structure without being restricted to the width condition.
請求項２の発明によると、金具本体における天板の下面に姿勢補助部材を固定し、この姿勢補助部材の下部で金具本体の幅方向に沿う両側の位置に一対の補助脚を設けたので、金具本体を下地材の上に仮置きしたとき、床材における凹溝の下側突部と押圧部の間に高さ寸法の差があっても、金具本体の幅方向を補助脚で支持することで倒れの発生を防ぐことができ、仮置き姿勢を確保することでビスのねじ込みによる床材の固定が確実に行えると共に、姿勢補助部材における筒軸の下端に設けた一対の補助脚が、筒軸の下端から下部広がりの傾斜状配置となるよう形成されているので、この補助脚はビスのねじ込みによる床材の固定時に座屈のような形状変化をして金具本体の下降を許容することで、床材における凹溝の下側突部と押圧部の間に高さ寸法の差があっても、床材の押圧固定が確実に得られることになる。 According to the invention of claim 2 , since the posture auxiliary member is fixed to the lower surface of the top plate of the metal fitting body, and the pair of auxiliary legs are provided at positions on both sides along the width direction of the metal fitting main body at the lower portion of the posture auxiliary member. When the bracket body is temporarily placed on the base material, the width direction of the bracket body is supported by the auxiliary legs even if there is a difference in height between the lower protrusion of the groove in the flooring and the pressing portion. Can prevent the occurrence of falling, and by securing the temporary placement posture, it is possible to securely fix the flooring by screwing screws, and a pair of auxiliary legs provided at the lower end of the cylindrical shaft in the posture auxiliary member, Since it is formed so as to have an inclined arrangement extending downward from the lower end of the cylinder shaft, this auxiliary leg changes its shape like buckling when the flooring is fixed by screwing screws to allow the fitting body to descend. Of the lower protrusion of the groove and the pressing part of the floor material. Difference in height is even, so that the pressing fixation of flooring can be surely obtained on.

By press-fitting, the posture auxiliary member 16 is fixedly attached to the metal fitting body 15.
前記筒軸２０は、前記支持脚１４、１４よりも短い上下長さを有し、上下軸心に沿ってビス１７の雄ねじ軸１７ａをねじ込むことができる縦孔２５がビス挿通孔１８と同軸心の配置で形成され、前記縦孔２５はビス１７を縦にねじ込む場合の誘導孔となり、この筒軸２０の下端で両側に設けた一対の補助脚２１、２１は、下端が前記支持脚１４の下端と同じ高さ位置かそれよりも少し下方に位置し、図４のように、筒軸２０の下端から下部広がりの傾斜状配置となるよう形成され、この両補助脚２１、２１の下端に外方へ屈曲する接地片２１ａが設けられている。なお、前記した支持脚１４、１４又は及び筒軸２０の幅が両側に並列する床材ｂ、ｂ間に生じる目地隙間となり、また、図示の場合、筒軸２０の外面で腕板２２の長さ方向の両側位置に補強用のリブ２６、２６が設けてある。 The cylindrical shaft 20 has a shorter vertical length than the support legs 14, and a vertical hole 25 into which the male screw shaft 17 a of the screw 17 can be screwed along the vertical axis is coaxial with the screw insertion hole 18. The vertical hole 25 serves as a guide hole when the screw 17 is screwed vertically. A pair of auxiliary legs 21 and 21 provided on both sides at the lower end of the cylindrical shaft 20 has a lower end at the lower end of the support leg 14. It is located at the same height as the lower end or slightly below it, and as shown in FIG. A grounding piece 21a that bends outward is provided. The width of the support legs 14 and 14 and the cylinder shaft 20 is a joint gap formed between the floor materials b and b arranged in parallel on both sides, and in the illustrated case, the length of the arm plate 22 on the outer surface of the cylinder shaft 20. Reinforcing ribs 26 and 26 are provided at both lateral positions.
この発明の固定具１１は、前記のような構成であり、長さ方向の両側に凹溝ｃが設けられた床材ｂを用い、この床材ｂを根太や大引き等の下地材ａに対して並列状に並べてデッキを構築するとき、床材ｂを下地材ａに固定するために使用される。 The fixture 11 according to the present invention is configured as described above, and uses a floor material b provided with concave grooves c on both sides in the length direction. The floor material b is used as a base material a such as a joist or a large pull. On the other hand, when the deck is constructed in parallel, it is used to fix the floor material b to the base material a.
前記固定具１１は、図１のように、金具本体１５の下面に姿勢補助部材１６を重ねて固定し、天板１２のビス挿通孔１８から姿勢補助部材１６の縦孔２５にビス１７をねじ込んで建て込んでおき、図６(ａ)のように、床材ｂを支持する下地材ａの上にこの固定具１１を載置し、一方の押圧部１３を床材ｂの凹溝ｃ内に挿入し、一対の支持脚１４、１４又は及び補助脚２３、２３によって固定具１１を下地材ａの上に自立させ、仮置状態とする。なお、図４の場合、金具本体１５の支持脚１４、１４よりも姿勢補助部材１６の補助脚２３、２３を少し長くした例を示し、図３のように、固定具１１は下地材ａの上に仮置した自立状態は補助脚２３、２３で保持され、支持脚１４、１４が下地材ａから少し浮いた状態になっている。 As shown in FIG. 1, the fixture 11 has a posture auxiliary member 16 overlapped and fixed to the lower surface of the metal fitting body 15, and screws 17 are screwed into the vertical holes 25 of the posture auxiliary member 16 from the screw insertion holes 18 of the top plate 12. As shown in FIG. 6 (a), the fixture 11 is placed on the base material a that supports the floor material b, and one pressing portion 13 is placed in the groove c of the floor material b. The fixing tool 11 is self-supported on the base material a by the pair of support legs 14 and 14 and the auxiliary legs 23 and 23 to be temporarily placed. 4 shows an example in which the auxiliary legs 23 and 23 of the posture auxiliary member 16 are slightly longer than the support legs 14 and 14 of the metal fitting body 15, and the fixture 11 is made of the base material a as shown in FIG. The self-standing state temporarily placed above is held by the auxiliary legs 23, 23, and the support legs 14, 14 are slightly lifted from the base material a.
このとき、床材ｂにおける下側突部ｄの高さ寸法に多少の誤差があって、押圧部１３の高さ寸法より下側突部ｄの高さ寸法が少し高い場合、固定具１１が床材ｂから離れる幅方向の外側に向けて傾こうとしても、固定具１１の幅方向両側に位置するよう姿勢補助部材の補助脚２１、２１が、下地材ａに当接することで固定具１１の倒れ発生を防いで仮置状態を保つことができる。 At this time, when there is some error in the height dimension of the lower protrusion d in the floor material b, and the height dimension of the lower protrusion d is slightly higher than the height dimension of the pressing portion 13, the fixture 11 is Even if it tries to incline toward the outer side in the width direction away from the floor material b, the auxiliary legs 21 and 21 of the posture auxiliary member abut on the base material a so as to be positioned on both sides of the fixing tool 11 in the width direction. Can be kept in a temporary state.
このような固定具１１の仮置状態から、姿勢補助部材１６における筒軸２０の側面及びその下端の一方補助脚２３を床材ｂの側面に当接させるように、前記固定具１１を横方向に押す。このとき、上記一方補助脚２３は、下部広がりになっており、しかも開脚弾性を有しているので、床材ｂの側面に対して押し付けられることで該側面に沿うことになり、この補助脚２３の下端に設けた接地片２１ａの先端は、床材ｂの側面下部のコーナーにある面取りやアールによって生じている僅かな隙間に臨み、この状態でビス１７を下地材ａに向けて途中までねじ込み、固定具１１を仮固定の状態にし、次に、前記床材ｂの横に新たな床材ｂを並列状に配置して下地材ａの上に載置し、図６（ｂ）に示したように、この新たな床材ｂの下側突部ｄを他方押圧部１３の下に差し込むようにする。 From such a temporarily placed state of the fixture 11, the fixture 11 is moved in the lateral direction so that the side surface of the cylindrical shaft 20 of the posture assisting member 16 and the one auxiliary leg 23 at the lower end thereof are brought into contact with the side surface of the floor material b. Press to. At this time, the one auxiliary leg 23 is widened at the bottom and has open leg elasticity, so that the auxiliary leg 23 is pressed against the side surface of the flooring b and is along the side surface. The tip of the grounding piece 21a provided at the lower end of the leg 23 faces a slight gap generated by chamfering or rounding at the corner at the lower side of the flooring b, and in this state the screw 17 is directed toward the base material a. Until the fixture 11 is temporarily fixed, and a new floor material b is arranged in parallel next to the floor material b and placed on the base material a, as shown in FIG. As shown in Fig. 5, the lower protrusion d of the new floor material b is inserted under the other pressing portion 13.
前記床材ｂの横に新たな床材ｂを並列状に配置した仮固定の状態で、両床材ｂ、ｂ間の目地隙間から工具を挿入してビス１７をねじ込み、ビス１７が金具本体１５の天板１２を介して固定具１１全体を押し下げると、押し下げ力の加わった固定具１１は、支持脚１４、１４が押し広げられると共に補助脚２１、２１が座屈のようなような形状変化をすることで天板１２が下降し、両押圧部１３、１３が両床材ｂ、ｂの下側突部ｄ、ｄを押し下げることで両床材ｂ、ｂを下地材ａに対して本固定する（図６（ｂ）に示す状態）。上記ビス１７のねじ込みによる本固定時に金具本体１５の天板１２が押し下げられると、合成樹脂の開脚弾性を有する補助脚２１、２１は、床材ｂの側面をこの床材ｂの幅方向に押圧するが、前記側面に圧接する状態で上から押されて座屈のような形状変化をすることで前記金具本体１５の下降を可能にしている。 In a temporarily fixed state in which a new floor material b is arranged in parallel next to the floor material b, a tool is inserted from a joint gap between both floor materials b and b and a screw 17 is screwed. When the entire fixture 11 is pushed down through the top plate 12 of the 15, the fixture 11 to which the pushing force is applied is shaped such that the support legs 14 and 14 are spread and the auxiliary legs 21 and 21 are buckled. By changing, the top plate 12 is lowered, and both pressing parts 13, 13 push down the lower projections d, d of both floor materials b, b, thereby lowering both floor materials b, b with respect to the base material a. This is fixed (state shown in FIG. 6B) . When the top plate 12 of the metal fitting body 15 is pushed down during the main fixing by screwing the screws 17, the auxiliary legs 21 and 21 having the open leg elasticity of the synthetic resin have the side surfaces of the floor material b in the width direction of the floor material b. Although pressed, the metal fitting body 15 can be lowered by being pressed from above in a state of being pressed against the side surface and undergoing a shape change such as buckling.
この本固定により、押圧部１３、１３の両端に設けた爪１９が下側突部ｄに対して食い込み、床材ｂと固定具１１が結合固定化されることにより、両床材ｂ、ｂは、長さ方向に移動しないよう固定化されると同時に、幅方向にも移動しないように固定化され、床材の横ずれ発生を確実に防止することができる。 By this permanent fixing, the claws 19 provided at both ends of the pressing portions 13 and 13 bite into the lower protrusion d, and the floor material b and the fixture 11 are coupled and fixed, whereby both floor materials b and b Is fixed so as not to move in the length direction and at the same time is fixed so as not to move in the width direction, and it is possible to reliably prevent the occurrence of lateral displacement of the flooring.
前記のような固定具１１による床材ｂの固定を各下地材ａの部分で行い、このようにして床材ｂを順次並列配置することで、デッキを構築することができる。 The deck material can be constructed by fixing the floor material b by the fixing tool 11 as described above at each base material a portion and sequentially arranging the floor material b in this way.
構築後のデッキにおいて、損傷などの発生した固定具１１を新たなものと取り換えるには、並列する両床材ｂ、ｂ間の隙間から工具を差し込んでビス１７を緩め、固定具１１の下地材ａ及び床材ｂ、ｂに対する固定を解き、工具によって固定具１１を床材間の隙間の長さ方向に移動させ、この隙間の端部から固定具１１を取り出す。 In the constructed deck, in order to replace the damaged fixture 11 with a new one, a tool is inserted through the gap between the parallel floor materials b, b to loosen the screws 17, and the base material of the fixture 11 is replaced. The fixing to a and the floor materials b and b is released, the fixture 11 is moved in the length direction of the gap between the floor materials by a tool, and the fixture 11 is taken out from the end of the gap.
前記した固定具１１の取り出し作業と逆に、隙間の端部から新たな固定具１１を挿入し、この新たな固定具１１を工具で床材ｂ、ｂ間の隙間の長さ方向に移動させ、下地材ａの上でビス１７をねじ込むことで床材ｂ、ｂの固定が行えることになる。 Contrary to the above-described work of removing the fixture 11, a new fixture 11 is inserted from the end of the gap, and this new fixture 11 is moved in the length direction of the gap between the floor materials b and b with a tool. The floor materials b and b can be fixed by screwing the screws 17 on the base material a.
このような固定具１１の取換え作業を利用して、損傷の生じた床材ｂを部分的に交換することも行え、取換えんとする床材ｂの両側において固定具１１の取り外しを行い、床材ｂを取り除いた部分に新たな床材ｂを配置し、床材ｂ、ｂ間の隙間端部から挿入した固定具１１を下地材ａにねじ込み固定するようにすればよい。 By using such a replacement work of the fixing tool 11, the damaged flooring b can be partially replaced, and the fixing tool 11 is removed on both sides of the flooring b to be replaced. Then, a new floor material b may be disposed in a portion where the floor material b is removed, and the fixing tool 11 inserted from the end of the gap between the floor materials b and b may be screwed and fixed to the base material a.
なお、前記した固定具１１の使用は、金具本体１５に姿勢補助部材１６を組み合わせたが、姿勢補助部材１６の使用を省き、金具本体１５とビス１７の組み合わせを使用して床材ｂの固定を行うことができる。 Although the use of the fixture 11 described above combines the posture assisting member 16 with the metal fitting body 15, the use of the posture auxiliary member 16 is omitted and the combination of the metal fitting main body 15 and the screw 17 is used to fix the floor material b. It can be performed.
