Description

本発明は、建築物のテラスやバルコニーなどに用いられるデッキ構造、特に、建築廃材などの木粉とプラスチックとの混合材を原料として成形されるデッキ材を用いたデッキ構造の改良に関するものである。 The present invention relates to a deck structure used for a terrace or balcony of a building, and more particularly to an improvement of a deck structure using a deck material formed from a mixed material of wood powder and plastic such as building waste. .

従来より、木粉とプラスチックとを原料とするデッキ材を用いるこの種のデッキ構造では、デッキ材を構成する木質成分が気温の寒暖や湿度による影響を受けて、収縮、膨張、膨潤し易いという性質があり、デッキ材が膨張、膨潤により変形して互いに密着した場合には、排水性が阻害されるという問題が生ずるので、デッキ材は予め施工の時点で相互に密着させずに、僅かながら隙間が保持できるように取付け施工される。 Conventionally, in this type of deck structure using a deck material made of wood powder and plastic, the wood component constituting the deck material is easily contracted, expanded and swollen due to the influence of temperature and humidity of the temperature. When the deck materials are deformed due to expansion and swelling and adhere to each other, there is a problem that the drainage is hindered. Therefore, the deck materials are not in close contact with each other at the time of construction in advance. Installation is performed so that the gap can be maintained.

このような事情から、この種のデッキ構造の基本形としては、根太の上面に、上端に水平方向に延びるフランジを設けた固定金具をネジ止めし、一方、デッキ材は、両側面に長さ方向に沿った凹溝を設けておいて、互いに隣接する左右のデッキ材の凹溝内へ前記固定金具のフランジの両側縁が係止されるように装着して、固定金具を介してデッキ材を根太に接続する構造が知られている。 For this reason, the basic form of this type of deck structure is that the top of the joist is screwed with a fixture that has a flange that extends in the horizontal direction at the upper end, while the deck material is lengthwise on both sides. Are installed so that both side edges of the flange of the fixing bracket are locked in the concave grooves of the left and right deck materials adjacent to each other. Structures that connect to joists are known.

特許文献１に示されるデッキ構造は、根太上にデッキ材を固定するための固定部材を取付けるが、この固定部材は、断面Ｕ字形のスペーサの底部を根太へネジ止めするとともに、上縁にそれぞれ外側方向へ延出するフランジを設けて、これらのフランジがデッキ材の両側面に設けられた凹溝内に係止される。 The deck structure shown in Patent Document 1 is provided with a fixing member for fixing the deck material on the joist, and this fixing member is screwed to the joist at the bottom of the U-shaped spacer and is attached to the upper edge respectively. Flange extending outwardly is provided, and these flanges are locked in concave grooves provided on both side surfaces of the deck material.

しかし、この固定部材の構造では、断面Ｕ字形スペーサの底部をネジで根太へ固定しても、Ｕ字形スペーサの底部と上方のフランジとの間の高さは一定なので、ネジによる締付け力は専らスペーサを根太に固定する手段として機能するだけで、上方のフランジをデッキ材の凹溝内へ圧着するための手段としては機能しない。そのため、フランジが単なる一枚の水平な板であると、このフランジが凹溝内で自由に動いてしまって、フランジによりデッキ材の凹溝を安定よく固定することができないという問題が生ずる。 However, in this structure of the fixing member, even if the bottom of the U-shaped spacer is fixed to the joist with a screw, the height between the bottom of the U-shaped spacer and the upper flange is constant, so the tightening force by the screw is exclusively used. It only functions as a means for fixing the spacer to the joist, and does not function as a means for crimping the upper flange into the recessed groove of the deck material. Therefore, if the flange is merely a single horizontal plate, the flange moves freely in the recessed groove, and there is a problem that the recessed groove of the deck material cannot be stably fixed by the flange.

このような理由から、この固定部材ではフランジの外縁を断面鈎形に折り曲げることで係止部を形成し、この鈎形の係止部がデッキ材の凹溝内へ嵌り込むことで、デッキ材が固定部材に固定されるような構造としているが、この構造では、フランジの外縁を、デッキ材の凹溝内へ適正に係合できるような、精度のある鈎形に折り曲げる加工が必要とされて工程が複雑となり、コスト高となるという問題と、前記のように、デッキ材の固定手段としては、鈎形係止部がデッキ材の凹溝内に係止されるだけで、ネジの締め付け力は鈎形係止部に伝えられないので、デッキ材の固定手段としては強度性に欠けるとともにガタツキが発生するという問題が指摘される。 For this reason, in this fixing member, the outer edge of the flange is bent into a hook-shaped cross section to form a locking portion, and this hook-shaped locking portion fits into the concave groove of the deck material. However, in this structure, it is necessary to bend the outer edge of the flange into an accurate bowl shape so that it can be properly engaged in the recessed groove of the deck material. The problem is that the process becomes complicated and the cost is high, and as described above, as a fixing means for the deck material, the hook-shaped locking portion is only locked in the concave groove of the deck material, and the screw is tightened. Since the force cannot be transmitted to the hook-shaped locking portion, there is a problem that the deck material fixing means lacks strength and generates rattling.

一方、特許文献２に示されたデッキ構造では、根太上にデッキ材を固定するための固定具が取付けられていて、この固定具は、根太に挿通されるネジと、このネジの上端に設けられた円盤状のフランジとからなっており、このフランジの相対向する両縁部が隣接するデッキ材の側面の凹溝内に嵌め込まれた状態で、ネジの下端に螺着したナットを締め付けることで、デッキ材が根太に圧着固定される構造となっている。 On the other hand, in the deck structure shown in Patent Document 2, a fixing tool for fixing the deck material is mounted on the joist, and this fixing tool is provided at a screw inserted into the joist and an upper end of the screw. Tighten the nut that is screwed to the lower end of the screw, with both opposing edges of the flange fitted in the concave groove on the side of the adjacent deck material. The deck material is fixed to the joists by pressure bonding.

このデッキ構造では、デッキ材の凹溝内に嵌め込んだ固定具のフランジを、ネジの下端に螺着したナットで締め付けて、ネジの締め付け力を利用してデッキ材を根太へ圧着固定することができるが、ネジの締め付け力をデッキ材と根太との圧着手段に用いるためには、ネジの下端にナットを螺着してナットを根太に締め付けなければならず、ネジの下端は根太の下方へ突出していて、上方からはその位置を正しく確認することができないために、ナットをネジの下端へ螺着する作業に手間取るという問題と、螺着したナットを締め付けるための作業が行いにくく、適切な締め付け力が得られないという問題を有している。 In this deck structure, the flange of the fixture fitted in the concave groove of the deck material is tightened with a nut screwed to the lower end of the screw, and the deck material is crimped and fixed to the joist using the tightening force of the screw. However, in order to use the tightening force of the screw as a means for crimping the deck material and joist, the nut must be screwed onto the lower end of the screw and the nut must be tightened to the joist. Since the position cannot be confirmed correctly from above, it is difficult to perform the work of screwing the nut onto the lower end of the screw, and the work of tightening the screwed nut is difficult to perform. Has a problem that a sufficient tightening force cannot be obtained.

本発明は、従来におけるこの種のデッキ構造の問題点を解消し、上下２枚の係止プレートの間をネジにより連結し、上方の係止プレートをデッキ材の側面凹溝内に装着した状態で、ネジを上方から挿入したドライバーにより締め付けることにより、簡単な操作で根太とデッキ材とを、ネジの締め付け力を用いて、しっかりと圧着固定でき、また、経年後のネジの弛みに対しても、デッキ材を取り外すことなく、各デッキ材の隙間の上からドライバーにより増し締めができるようにしたデッキ構造の提供を目的としたものである。 The present invention eliminates the problems of this type of conventional deck structure, connects the upper and lower two locking plates with screws, and mounts the upper locking plate in the side groove of the deck material. By tightening the screw with a screwdriver inserted from above, the joist and deck material can be firmly crimped and fixed using the tightening force of the screw with a simple operation. The purpose of this is also to provide a deck structure that can be tightened by a screwdriver from above the gap between the deck materials without removing the deck materials.

本発明はそのための具体的手段として、根太上に、床面を構成する複数のデッキ材が間隔をおいて平行に配列され、デッキ材と根太とが連結金具を介して一体に連結されるデッキ構造であって、デッキ材は、両側面に前記連結金具の押さえプレートを係止するための長さ方向に沿った凹溝を備えており、連結金具は、根太に固定される中央部にネジ孔を設けた受座プレートと、デッキ材両側面の凹溝内に係止される押さえプレートとの間が、上方から挿通したネジにより連結され、連結金具の受座プレートと押さえプレートとの間に、前記ネジの締め付けにより屈曲可能なセパレータが設けられていることを特徴とする。 In the present invention, as a specific means for that purpose, a deck in which a plurality of deck materials constituting a floor surface are arranged in parallel at intervals on the joists, and the deck materials and joists are integrally connected via a connecting metal fitting. The deck material is provided with a concave groove along the length direction for locking the holding plate of the coupling metal on both side surfaces, and the coupling metal is screwed at the center part fixed to the joist. Between the receiving plate with holes and the holding plate locked in the concave grooves on both sides of the deck material are connected by screws inserted from above, and between the receiving plate and the holding plate of the connecting bracket Further, a separator that can be bent by tightening the screw is provided.

このデッキ構造に用いられる根太としては、上面に連結金具の受座プレートを係止するための長さ方向に沿った凹溝を備えていることが好ましく、また、連結金具としては、受座プレートが、根太の前記凹溝内へ上方から落とし込める横幅と、凹溝内で回転することで凹溝内の両側縁内側に係止される長さとをもった長方形の板からなっていることが好ましい。 As the joist used in this deck structure, it is preferable that the upper surface is provided with a concave groove along the length direction for locking the receiving plate of the connecting metal, and as the connecting metal, the receiving plate However, it is made of a rectangular plate having a width that can be dropped into the groove of the joist from above and a length that is locked inside the both side edges of the groove by rotating in the groove. preferable.

一方、連結金具は、受座プレートが、根太の側面に配置されるブラッケトの垂直固定辺と直交する水平面からなっていて、前記垂直固定辺が根太にネジ止めされているような構造であってもよい。 On the other hand, the connecting bracket has a structure in which the receiving plate is formed of a horizontal plane orthogonal to the vertical fixed side of the bracket arranged on the side surface of the joist, and the vertical fixed side is screwed to the joist. Also good.

また、連結金具の受座プレートと押さえプレートとの間を保持するセパレータはプラスチックからなっていて、受座プレートのネジ孔の周囲に配置されたネジ貫通孔を有する基板と、この基板の両側から垂直に立ち上がる、ネジの太さより若干大きい横幅をもった左右一対の支持板とを備えていて、前記支持板の端部に突設した突片が、前記プレートにおけるネジ孔の周囲に開設した止め孔に係合されて、上下プレート間の間隔をセパレータの高さ位置に保持しているような構造が好ましい。 In addition, the separator that holds between the receiving plate and the holding plate of the coupling metal is made of plastic, and includes a board having screw through holes arranged around the screw holes of the receiving plate and both sides of the board. A pair of left and right support plates that rises vertically and has a width slightly larger than the thickness of the screw, and a protruding piece projecting from the end of the support plate is opened around the screw hole in the plate A structure in which the gap between the upper and lower plates is held at the height position of the separator is preferable.

このデッキ構造では、連結金具を、根太に固定される受座プレートと、デッキ材両側面の凹溝内に係止される押さえプレートとの間が、押さえプレートの上方から挿通して受座プレートのネジ孔へ螺着されるようなネジにより連結する構造としたので、押さえプレートをデッキ材の両側凹溝内へ係止して、この押さえプレートの上方に露呈するネジ頭部をネジ廻しにより回転すると、押さえプレートがネジにより締め付けられてデッキ材を根太へ圧着されるので、簡単な操作でデッキ材を根太に固定することができ、また、経年後のネジの弛みに対しても、デッキ材を取り外すことなく、各デッキ材の隙間の上からドライバーにより簡単に増し締めができる。 In this deck structure, the connecting bracket is inserted from above the holding plate between the receiving plate fixed to the joist and the holding plate locked in the concave grooves on both sides of the deck material. Since the structure is such that it is connected by screws that can be screwed into the screw holes, the presser plate is locked into the concave grooves on both sides of the deck material, and the screw head exposed above the presser plate is turned by screwing. When it rotates, the press plate is tightened with screws and the deck material is crimped to the joists, so that the deck materials can be fixed to the joists with a simple operation. Without removing the material, it can be easily tightened by a screwdriver from the top of each deck material.

連結金具は、押さえプレートと受座プレートとネジだけで構成すると、ネジの下端が受座プレートのネジ孔に螺着されていて、押さえプレートとは遊挿されて螺着されていないので、ネジに対して押さえプレートが自由に動いてしまい、取扱いにくいという問題があるが、押さえプレートと受座プレートとの間には、ネジの締め付けにより屈曲可能なセパレータが介挿されているので、押さえプレートと受座プレートとの間隔が常にこのセパレータにより規制されて、押さえプレートが勝手に動かず、従って、連結金具として扱いやすく、押さえプレートをデッキ材の凹溝内へ装着し易い構造とすることができる。 If the connecting bracket is composed only of a holding plate, a receiving plate and a screw, the lower end of the screw is screwed into the screw hole of the receiving plate, and it is loosely inserted into the holding plate and not screwed. However, there is a problem that the presser plate moves freely and is difficult to handle, but a separator that can be bent by screw tightening is inserted between the presser plate and the receiving plate. The distance between the receiving plate and the receiving plate is always regulated by this separator, so that the holding plate does not move freely, so it can be handled easily as a connecting bracket, and the holding plate can be easily installed in the recessed groove of the deck material. it can.

押さえプレートと受座プレートとの間隔を規制するセパレータは、ネジの両側に配置される左右一対の支持板が、ネジの太さより若干大きい横幅を有しているので、受座プレートを根太に係止して、押さえプレートをデッキ材の凹溝内へ係止した時に、隣接する左右のデッキ材の側面が、セパレータにおける支持板の両側縁の横幅に規制されて、全てのデッキ材が支持板の横幅と同じ幅間隔に保持されることになる。また、支持板の横幅はネジの太さより若干大きいので、内側にあるネジが、左右のデッキ材の側面により圧迫されることがなく、ネジを常に回転し易い状態に維持することができる。 In the separator that regulates the distance between the holding plate and the receiving plate, the pair of left and right support plates arranged on both sides of the screw has a width that is slightly larger than the thickness of the screw. When the presser plate is locked into the recessed groove of the deck material, the side surfaces of the adjacent left and right deck materials are regulated by the lateral width of both side edges of the support plate in the separator, and all deck materials are supported by the support plate. It is held at the same width interval as the horizontal width of. Further, since the lateral width of the support plate is slightly larger than the thickness of the screw, the screw on the inner side is not compressed by the side surfaces of the left and right deck members, and the screw can be maintained in a state where it is always easy to rotate.

本発明を実施するに際しては、デッキ材を固定するための根太として、上面に連結金具の下端係止辺の横幅を落とし込めるような横幅をもった凹溝を長さ方向に沿って設けておき、連結金具の受座プレートを上方から前記根太の凹溝内へ落とし込んで凹溝内で回転することにより、連結金具の受座プレートを凹溝の両側縁内側に係止できるようにし、連結金具の受座プレートをネジ止めすることなく根太に固定できるような構造とすることが好ましい。 In carrying out the present invention, as a joist for fixing the deck material, a concave groove having a lateral width is provided along the length direction so that the lateral width of the lower end locking side of the connecting bracket can be dropped on the upper surface. By dropping the receiving plate of the connecting bracket into the joist groove from above and rotating in the groove, the receiving plate of the connecting bracket can be locked inside the both side edges of the recessed groove. It is preferable that the seat plate be fixed to the joist without screwing.

次に、本発明に係るデッキ構造を図面に示す実施例について説明すると、このデッキ構造は、図１に示すように、根太１と、この根太１の上面に間隔をおいて平行に配列されて床面を構成する複数のデッキ材２と、前記根太１に前記デッキ材２を連結固定するための連結金具３とから基本的に構成されている。 Next, an embodiment shown in the drawing of the deck structure according to the present invention will be described. As shown in FIG. 1, the deck structure is arranged in parallel with a joist 1 and an upper surface of the joist 1 with a space therebetween. It is basically composed of a plurality of deck materials 2 constituting the floor surface and a connecting metal fitting 3 for connecting and fixing the deck material 2 to the joists 1.

デッキ材２は、木材、またはプラスチックからなるもの、または、廃材を利用した木粉とプラスチックとを混合した加工性、耐久性に優れた合成木材などからなっており、両側面の長さ方向に沿った中央位置にそれぞれ板厚の略３分の１程度の幅の凹溝４が設けられ、この凹溝４内に前記連結金具３の押さえプレート５が挿着されることで、隣接する一対のデッキ材２の相対向する側面２ａが、所定の間隔Ｗ１をおいて根太１に取り付けられるように構成されている。 The deck material 2 is made of wood or plastic, or is made of synthetic wood with excellent processability and durability, which is a mixture of wood powder and plastic using waste materials. A concave groove 4 having a width of about one-third of the plate thickness is provided at the center position along the center, and the holding plate 5 of the connecting metal fitting 3 is inserted into the concave groove 4 so that a pair of adjacent grooves is provided. The opposite side surfaces 2a of the deck material 2 are configured to be attached to the joists 1 at a predetermined interval W1.

この実施例で使用される根太１は、図６に示すうように、アルミ製の角材からなっていて、デッキ材２が配置されることになる上面１ａには、連結金具３の受座プレート６を係止するための長さ方向に沿った凹溝７が設けられている。この凹溝７の開口幅Ｗ２は、連結金具３の受座プレート６を、その長さ方向が凹溝７の長さ方向と平行になるような向きにして凹溝７内へ上方から落とし込めるような大きさとなっていて、連結金具３の受座プレート６が凹溝７内に落とし込まれた後に、受座プレート６を凹溝７内で９０度回転することで、受座プレート６の長さ方向に沿った両端部６ａが凹溝７の両側縁７ａの内側に係止されるように構成されている。 As shown in FIG. 6, the joist 1 used in this embodiment is made of aluminum square material, and on the upper surface 1a on which the deck material 2 is to be disposed, the receiving plate of the connecting fitting 3 is provided. A concave groove 7 is provided along the length direction for locking 6. The opening width W2 of the concave groove 7 allows the receiving plate 6 of the connecting fitting 3 to be dropped into the concave groove 7 from above with the length direction thereof being parallel to the length direction of the concave groove 7. After the receiving plate 6 of the connecting fitting 3 is dropped into the concave groove 7, the receiving plate 6 is rotated 90 degrees in the concave groove 7, so that the receiving plate 6 Both end portions 6 a along the length direction are configured to be locked inside the side edges 7 a of the groove 7.

図６に示すように、根太１の凹溝７は、内側に凹溝７の開口幅Ｗ２よりも広い間隔をおいて設けられた隔壁９と、これらの隔壁９の間を結ぶ底板１０とからなる補強枠８が設けられるように構成されており、図６では、この補強枠８を有する凹溝７が根太１の四辺のうち一辺にだけ設けられた例を示しているが、この凹溝７は根太１の四辺に設けられるような構造としてもよい。 As shown in FIG. 6, the groove 7 of the joist 1 includes a partition wall 9 provided on the inner side at a larger interval than the opening width W <b> 2 of the recess groove 7, and a bottom plate 10 connecting the partition walls 9. FIG. 6 shows an example in which the groove 7 having the reinforcement frame 8 is provided on only one side of the four sides of the joist 1, but this groove is shown in FIG. 7 may have a structure provided on the four sides of the joist 1.

一方、根太１とデッキ材２とを連結する連結金具３は、図２乃至図４に示すように、根太１に固定されるための受座プレート６と、デッキ材２の両側面の凹溝４に係止されるための押さえプレート５と、両方のプレート５，６間に挿通されるネジ１１と、押さえプレート５と受座プレート６との間に挿通されたネジ１１を締め付けることで、両方のプレート５，６を所定の間隔に保持するためのセパレータ１２とから構成されている。 On the other hand, as shown in FIGS. 2 to 4, the connecting fitting 3 for connecting the joist 1 and the deck material 2 includes a receiving plate 6 for fixing to the joist 1 and concave grooves on both side surfaces of the deck material 2. By tightening the presser plate 5 to be locked to 4, the screw 11 inserted between both plates 5, 6, and the screw 11 inserted between the presser plate 5 and the seat plate 6, It consists of a separator 12 for holding both plates 5 and 6 at a predetermined interval.

図１乃至図７に示す実施例の連結金具３では、受座プレート６が、根太１の上面に設けられた幅Ｗ２を有する凹溝７内へ上方から落とし込めるような横幅と、長さ方向に沿った両側縁を下方へ直角に折り曲げた補強辺１３とを備えた長方形の金属板からなっていて、中央部に前記ネジ１１の下端を螺着するためのネジ孔１４を有している。 In the connecting metal fitting 3 of the embodiment shown in FIGS. 1 to 7, a lateral width such that the receiving plate 6 can be dropped from above into a concave groove 7 having a width W2 provided on the upper surface of the joist 1, and a length direction. And has a screw hole 14 for screwing the lower end of the screw 11 at the center. .

また、上方の押さえプレート５は、両側縁がデッキ材両側面２ａの凹溝４内に係止されるような、前記受座プレート６の横幅よりも大きい長方形の金属板からなっていて、中央部にはネジ１１を自由に通す挿通孔１５が設けられており、このネジ挿通孔１５に頭１１ａを上にしたネジ１１が挿通され、ネジ１１の下端が下方の受座プレート６のネジ孔１４に螺着されている。 Further, the upper holding plate 5 is made of a rectangular metal plate that is larger than the lateral width of the receiving plate 6 so that both side edges are locked in the recessed grooves 4 of the deck material side surfaces 2a. The part is provided with an insertion hole 15 through which the screw 11 can freely pass. The screw 11 with the head 11a up is inserted into the screw insertion hole 15, and the lower end of the screw 11 is the screw hole of the lower receiving plate 6 14 is screwed.

一方、セパレータ１２は、連結金具３の受座プレート６と押さえプレート５との間を所定の間隔に保持するためのもので、プラスチックからなっており、受座プレート６のネジ孔１４の周囲に配置された環状の基板１６と、この基板１６の両側から垂直に上方へ立ち上がる左右一対の支持板１７とを備えている。 On the other hand, the separator 12 is for holding a space between the receiving plate 6 and the holding plate 5 of the coupling metal 3 at a predetermined interval, and is made of plastic, around the screw hole 14 of the receiving plate 6. An annular substrate 16 is provided, and a pair of left and right support plates 17 rising vertically from both sides of the substrate 16 are provided.

上記左右一対の支持板１７は、図４に示すように、その横幅についてみると、ネジ１１の太さより若干大きい横幅Ｗ３を有しており、また、図５に示すように、長さについては、デッキ材凹溝４の下縁４ａからデッキ材下面２ｂまでの長さｈ１に、根太１の凹溝７の肉厚ｈ２を加えた長さより若干大きい長さＨからなっている。さらに、前記支持板１７の上下両端に突片１８，１９が設けられており、これらの突片１８，１９が、受座プレート６と押さえプレート５のネジ孔１４の周囲に開設した止め孔２０，２１に嵌め込まれて、支持板１７が上下のプレート５，６間の所定の位置に安定よく保持されるようになっている。 As shown in FIG. 4, the pair of left and right support plates 17 have a width W3 that is slightly larger than the thickness of the screw 11 in terms of the width, and as shown in FIG. The length H1 is slightly larger than the length h1 from the lower edge 4a of the deck material groove 4 to the bottom surface 2b of the deck material plus the thickness h2 of the groove 7 of the joist 1. Further, projecting pieces 18, 19 are provided at both upper and lower ends of the support plate 17, and these projecting pieces 18, 19 are formed in the retaining holes 20 formed around the receiving plate 6 and the screw holes 14 of the holding plate 5. , 21 so that the support plate 17 is stably held at a predetermined position between the upper and lower plates 5, 6.

上記セパレータ１２は、左右の支持板１７が上下両プレート５，６間に挿着されたネジ１１の両側位置に、ネジ１１と平行して配列されるので、ネジ１１を上方から締め付けると、上下両プレート５，６の間隔が収縮することに伴って支持板１７が屈曲変形し、両プレート５，６に締め付け力に対する反力を伝える。 Since the separator 12 is arranged in parallel with the screw 11 at both side positions of the screw 11 with the left and right support plates 17 inserted between the upper and lower plates 5 and 6, when the screw 11 is tightened from above, As the distance between the plates 5 and 6 contracts, the support plate 17 is bent and deformed, and a reaction force against the clamping force is transmitted to the plates 5 and 6.

デッキ材２の取付け施工に際しては、図１のように、根太１の上方にデッキ材２を直交するように配列し、図７に鎖線で示すように、連結金具３の受座プレート６を、その長さ方向が根太１の凹溝７の長さ方向と平行するような向きとして凹溝７内へ落とし込み、次いで連結金具３を実線と点線で示すように９０度回転して、受座プレート６の長さ方向を根太凹溝７の長さ方向と交差させ、受座プレート６の両端部６ａを凹溝７の両側縁内側７ａに係止させる。 When mounting the deck material 2, as shown in FIG. 1, the deck material 2 is arranged so as to be orthogonal above the joists 1, and the receiving plate 6 of the coupling metal 3 is attached as shown by a chain line in FIG. The lengthwise direction is dropped into the groove 7 so that the length direction is parallel to the length direction of the groove 7 of the joist 1, and then the connecting fitting 3 is rotated 90 degrees as shown by the solid line and the dotted line, The length direction of 6 intersects the length direction of the joist groove 7, and both end portions 6 a of the receiving plate 6 are engaged with the inner side edges 7 a of both sides of the groove 7.

図７のように、連結金具３の受座プレート６を凹溝７内へ落とし込む際に、誤って連結金具３を手から離して落としてしまっても、上方の押さえプレート５の横幅の方が受座プレート６の横幅よりも大きいので、連結金具３が根太の凹溝７を通して下方へ落下して紛失することはない。 As shown in FIG. 7, even when the receiving plate 6 of the connecting fitting 3 is dropped into the concave groove 7, even if the connecting fitting 3 is accidentally dropped from the hand, the lateral width of the upper holding plate 5 is larger. Since it is larger than the lateral width of the receiving plate 6, the connecting fitting 3 does not fall down through the joist groove 7 and is not lost.

図１に示すように、受座プレート６を根太凹溝７内に係止した後、ネジ１１を少し緩めておいて、連結金具３を根太凹溝７の長さ方向に沿って左側のデッキ材２の凹溝４の方向へ移動させ、その状態で押さえプレート５の片方の側縁５ａをデッキ材凹溝４の上に楽に係合できるようにする。次いで、隣接する右側のデッキ材２を矢印の方向へ移動して、このデッキ材２の凹溝４へ前記連結金具３の押さえプレート５の他方の側縁５ａを係合する。 As shown in FIG. 1, after the seat plate 6 is locked in the joist groove 7, the screw 11 is slightly loosened, and the connecting metal fitting 3 is connected to the left deck along the length direction of the joist groove 7. The material 2 is moved in the direction of the concave groove 4, and in this state, one side edge 5 a of the pressing plate 5 can be easily engaged with the deck material concave groove 4. Next, the adjacent right deck material 2 is moved in the direction of the arrow, and the other side edge 5 a of the holding plate 5 of the coupling metal 3 is engaged with the concave groove 4 of the deck material 2.

図１及び図５に示すように、押さえプレート５の両側縁５ａが隣接する一対のデッキ材２のそれぞれの凹溝４内へ係止されると、先に受座プレート６を根太凹溝７内で９０度回転したことにより、セパレータ１２における左右の支持板１７の横幅Ｗ３がデッキ材２の両側面２ａと直交する向きに配置されることになる。そのため、左右のデッキ材２の両側面２ａは、左右の支持板１７の両側縁と接触して、支持板１７を挟んだ位置で所定の幅間隔Ｗ１に保持されることになる。 As shown in FIGS. 1 and 5, when both side edges 5 a of the pressing plate 5 are locked into the respective recessed grooves 4 of the pair of adjacent deck members 2, the receiving plate 6 is first moved into the joist groove 7. The horizontal width W3 of the left and right support plates 17 in the separator 12 is arranged in a direction orthogonal to the both side surfaces 2a of the deck material 2. Therefore, both side surfaces 2a of the left and right deck members 2 come into contact with both side edges of the left and right support plates 17 and are held at a predetermined width interval W1 at a position sandwiching the support plates 17.

上記のように、左右のデッキ材２の両側面２ａが左右の支持板１７の両側縁と接触して、支持板１７を挟んだ所定の幅間隔Ｗ１の位置に保持されると、左右の支持板１７の横幅Ｗ３はネジ１１の外径よりも大きいので、ネジ１１が左右のデッキ材２の両側面２ａと接触して回転を阻害されるということがなく、幅間隔Ｗ１に保持されたデッキ材両側面２ａの上方から挿入したネジ廻し２２により楽に回転でき、押さえプレート５をデッキ材凹溝４に具合よく圧着固定できる。そため、気温の変化による膨張・収縮に伴ったメンテナンスが必要となる場合に適切に対応することができる。 As described above, when the both side surfaces 2a of the left and right deck members 2 are in contact with both side edges of the left and right support plates 17 and are held at the predetermined width interval W1 across the support plates 17, the left and right support members are supported. Since the lateral width W3 of the plate 17 is larger than the outer diameter of the screws 11, the screws 11 do not come into contact with both side surfaces 2a of the left and right deck members 2 and are not inhibited from rotating, and the deck is held at the width interval W1. The screw plate 22 inserted from above the material side surfaces 2a can be rotated easily, and the pressing plate 5 can be pressed and fixed to the deck material groove 4 in a good manner. Therefore, it is possible to appropriately cope with a case where maintenance accompanying expansion / contraction due to a change in temperature is required.

図８乃至図９は別の実施例を示しており、この実施例は凹溝を備えていない根太３１を使用する場合のものである。この場合には、根太３１に連結金具を係止するための凹溝が設けられていないので、連結金具３３は、受座プレート３６が根太３１の側面に配置されるブラッケト３８の垂直固定辺３９と直交する水平面からなっていて、前記垂直固定辺３９が根太３１の側面に止めネジ４０を差し込むことにより固定支持されている。 FIG. 8 to FIG. 9 show another embodiment, and this embodiment is a case where the joist 31 having no concave groove is used. In this case, since the groove for locking the connection fitting is not provided in the joist 31, the connection fitting 33 has the vertical fixing side 39 of the bracket 38 on which the receiving plate 36 is disposed on the side surface of the joist 31. The vertical fixing side 39 is fixedly supported by inserting a set screw 40 into the side face of the joist 31.

受座プレート３６の両側には、垂直固定辺３９との間に補強側板４３が設けられているとともに、垂直固定辺３９の背面には根太３１の上面に係止される鈎型の案内板４４が一体的に設けられていて、この案内板４４の上面４４ａによりブラッケト３８と連結金具３３を根太３１の側面の所定の高さ位置に保持し、かつ、根太３１の長さ方向に沿ってデッキ材３２の方向へスライドできるようになっている。なお、連結金具３３の受座プレート３６にはネジ孔３７が設けられていて押さえプレート３５との間にネジ４５が挿着されていること、また、受座プレート３６と押さえプレート３との間にセパレータ４２が設けられる点については先の実施例の構成と同じである。 On both sides of the receiving plate 36, reinforcing side plates 43 are provided between the receiving plate 36 and the vertical fixed side 39, and a hook-shaped guide plate 44 that is locked to the upper surface of the joist 31 on the back surface of the vertical fixed side 39. Are integrally provided, and the upper surface 44a of the guide plate 44 holds the bracket 38 and the connecting bracket 33 at a predetermined height position on the side surface of the joist 31, and the deck along the length direction of the joist 31. It can slide in the direction of the material 32. The receiving plate 36 of the connection fitting 33 is provided with a screw hole 37 and a screw 45 is inserted between the receiving plate 36 and the receiving plate 36 and the holding plate 3. The separator 42 is provided with the same configuration as that of the previous embodiment.

この実施例の場合には、図８のように、いずれか一方のデッキ材例えば、左側のデッキ材３２を根太３１に固定した後、ラッケト３８を案内板４４により根太３１の側面に吊り掛けた状態で前記デッキ材３２の方向へスライドさせ、押さえプレート３５の一方の側縁３５ａをデッキ材３２の凹溝３４内に係止する。 In the case of this embodiment, as shown in FIG. 8, after fixing one of the deck materials, for example, the left deck material 32 to the joist 31, the racket 38 is hung on the side surface of the joist 31 by the guide plate 44. In this state, it is slid in the direction of the deck material 32, and one side edge 35 a of the pressing plate 35 is locked in the concave groove 34 of the deck material 32.

この状態でブラッケト３８の垂直固定辺３９を止めネジ４０により根太３１に固定し、次いで、右側の隣接するデッキ材３２を、矢印のようにデッキ材３２の方向へ押し込んで、押さえプレート３５の他方の側縁３５ａをデッキ材３２の凹溝３４内に係止する。そして、最後に、両デッキ材３２の突き合わせ部上方から挿入したネジ廻し２２によりネジ４１を回転して、押さえプレート３５を両方のデッキ材の凹溝３４内へそれぞれ係止固定する。 In this state, the vertical fixing side 39 of the bracket 38 is fixed to the joist 31 with the set screw 40, and then the adjacent deck material 32 on the right side is pushed in the direction of the deck material 32 as shown by the arrow, The side edge 35a is locked in the groove 34 of the deck material 32. Finally, the screw 41 is rotated by the screwdriver 22 inserted from above the abutting portions of the two deck members 32, and the pressing plate 35 is locked and fixed in the concave grooves 34 of both deck members.

本発明に係るデッキ構造は、第１の実施例のように、根太１に凹溝４が設けられている場合には、連結金具３の受座プレート６を凹溝４内へ落とし込んで、凹溝４内で９０度回転するだけで簡単に根太１へ係合できるという便利さを有し、また、互いに付き合わされるデッキ材の両側面２ａの間隔Ｗ１が、セパレータ１２の支持板１７の横幅に規制されることで全て均一な隙間間隔で施工できるという仕上がりの美麗さを有するで点で利用性が高く、信頼性の高いデッキ構造とすることができる。。 In the deck structure according to the present invention, when the groove 1 is provided in the joist 1 as in the first embodiment, the receiving plate 6 of the connecting metal fitting 3 is dropped into the groove 4 to form the groove. It has the convenience that it can be easily engaged with the joist 1 simply by rotating 90 degrees in the groove 4, and the interval W1 between the two side surfaces 2a of the deck members attached to each other is the width of the support plate 17 of the separator 12. Therefore, it is possible to obtain a deck structure with high usability and high reliability because it has a beautiful finish that can be constructed with uniform gap intervals. .

また、押さえプレート５と受座プレート６とを連結するネジ１１が、セパレータ１２の支持板１７の横幅内に保護されていて、デッキ材の両側面２ａが完全に弛みなく接合されたとしても、ネジがデッキ材両側面２ａと接触して、デッキ材両側面間に挟着されることがないので、ネジ１１は隙間の上方から挿入したネジ廻しにより常に回転できる状態が維持され、補修・修理を簡単に行えるという利点を有する。 Moreover, even if the screw 11 that connects the holding plate 5 and the receiving plate 6 is protected within the lateral width of the support plate 17 of the separator 12 and the both side surfaces 2a of the deck material are joined together without looseness, Since the screw does not come into contact with both sides of the deck material 2a and is not sandwiched between the both sides of the deck material, the screw 11 can always be rotated by the screw inserted from above the gap, and repair / repair It has the advantage that it can be performed easily.
