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. .

従来よりこの種のデッキ構造としては、木粉とプラスチックとを原料とするデッキ材を用いる方式が知られているが、この種のデッキ材は、構成部材の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, as this type of deck structure, a method using a deck material made of wood powder and plastic is known, but this type of deck material is composed of the wood component of the component depending on the temperature and humidity of the temperature. The deck material has the property of being easily contracted, expanded, and swollen under the influence, and when the deck material is deformed by expansion and swelling and adheres to each other, there arises a problem that the drainage is hindered. Installation is performed so that a slight gap can be maintained without causing close contact with each other at the time of construction.

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ておき、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 with a flange that extends horizontally at the top end, while the deck material is long on both sides. A concave groove is provided along the vertical direction, and the left and right deck material adjacent to each other is fitted in the concave groove so that both side edges of the flange of the fixing bracket are locked, and the deck is inserted via the fixing bracket. A structure in which materials are connected to joists is known.

また、別のデッキ構造としては、デッキ材の横幅を載置できる長さをもった長方形の台座の両端上方に、それぞれデッキ材の両側縁に係合する保持部を設けるとともに、両端下方には、互いに隣接する台座を長さ方向に連結するための雄形係合部と雌形係合部とを設けて、複数個の台座を隣接する雄形係合部と雌形係合部とが係合するようにして連結配置する構造が知られている。
特開２００２−２０６２７６号公報 特開２００１−３１７１２１号公報 特開２００４−３６２７８号公報 As another deck structure, a holding portion that engages both side edges of the deck material is provided above both ends of the rectangular pedestal having a length capable of placing the width of the deck material, and below the both ends. A male engaging portion and a female engaging portion for connecting the pedestals adjacent to each other in the length direction, and the male engaging portion and the female engaging portion adjacent to each other are provided. Structures that are connected and arranged to be engaged are known.

特許文献１及び特許文献２に示されるデッキ構造は、いずれも、両側にデッキ材の両側面の凹溝内へ係止される係止辺を設けた固定金具を、一個ずつ根太上にネジによって固定し、この固定金具の両側に突出させた係止辺をデッキ材両側面の凹溝内へ嵌合してデッキ材を係止する構造であるため、固定金具を一個ずつ指先で保持しながら根太上にネジ止めしなければならず、固定金具の取付け位置が狂ったり、金具やネジを落したりするなど、金具の取付け作業に手間がかかって非能率であるという問題を有している。   In each of the deck structures shown in Patent Document 1 and Patent Document 2, fixing brackets provided with locking sides to be locked in the concave grooves on both sides of the deck material on both sides are screwed on the joists one by one. It is structured to lock the deck material by fitting the locking edges protruding on both sides of this fixing metal into the recessed grooves on both sides of the deck material, so holding the fixing metal one by one with your fingertips There is a problem that the mounting work of the metal fitting takes time and is inefficient, for example, the mounting position of the fixing metal is out of order or the metal fitting or the screw is dropped.

一方、特許文献３に示されるデッキ構造では、複数個の台座を隣接する雄形係合部と雌形係合部とが係合されるように連結配置して、それぞれの台座上にデッキ材を嵌め込んで、台座の両端に設けられた保持部によりデッキ材の両側縁に係合するので、複数個の台座を、雄形係合部と雌形係合部とにより根太上に組み立て配置する作業や、台座上にデッキ材を装着する作業が、特許文献１及び特許文献２の固定金具を用いる構造に比較して、はるかに能率化されるという利点を有している。   On the other hand, in the deck structure shown in Patent Document 3, a plurality of pedestals are connected and arranged so that adjacent male engaging portions and female engaging portions are engaged with each other, and the deck material is placed on each pedestal. Is engaged with both side edges of the deck material by holding portions provided at both ends of the pedestal, so a plurality of pedestals are assembled and arranged on the joist by the male engaging portion and the female engaging portion. Compared with the structure using the fixing metal fittings of Patent Document 1 and Patent Document 2, the work to perform and the work of mounting the deck material on the pedestal have the advantage that they are much more efficient.

しかし、この特許文献３のデッキ構造では、台座の両端にデッキ材の両側縁を固定する保持部が設けられているので、台座の長さによって載置されるデッキ材の横幅寸法が決まってしまい、各種の横幅寸法のデッキ材を載置するためには、それぞれのデッキ材の横幅寸法に対応した長さをもつ台座を、数種類用意しておいて、デッキ材の横幅寸法に応じて長さの異なる台座を使用しなければならないという問題を有している。   However, in the deck structure disclosed in Patent Document 3, since the holding portions for fixing both side edges of the deck material are provided at both ends of the pedestal, the width of the deck material to be placed is determined by the length of the pedestal. In order to mount deck materials of various width dimensions, prepare several types of pedestals with lengths corresponding to the width dimensions of the respective deck materials, and the length according to the width dimensions of the deck materials. Different pedestals must be used.

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するため、デッキ材を配列固定するための接続部材の基板に設けられる雌形凹部と雄形突起とを、基板の長さ方向に沿って連結することで、連結される各接続部材の長さをデッキ材の横幅に応じて可変できるようにして、長短二種類の接続部材によって数種類の横幅寸法のデッキ材を取付けられるようにしたデッキ構造の提供を目的とするものである。   In order to eliminate the problems of this type of conventional deck structure, the present invention provides a female concave portion and a male projection provided on the substrate of the connecting member for arranging and fixing the deck material in the length direction of the substrate. By connecting together, the length of each connecting member to be connected can be changed according to the width of the deck material, so that deck materials of several kinds of width dimensions can be attached by two kinds of connecting members, long and short The purpose is to provide a deck structure.

本発明はそのための具体的手段として、平行に配列されて床面を構成する複数のデッキ材と、これらのデッキ材の長さ方向と直交する向きに互いに連結して配置され、その上面にデッキ材を配列固定するための複数個の接続部材とからなっていて、接続部材は、デッキ材の横幅を載置するための長さをもつ基板と、この基板内に凹設された雌形凹部と、基板の先端側に突設された雄形突起と、雌形凹部と雄形突起との間の基板上に突設されたデッキ材側縁の凹溝に係合する係止辺とを備えており、雌形凹部と雄形突起とは、一方の接続部材の雌形凹部に対して隣接する接続部材の雄形突起を、基板の長さ方向に沿って連結することで、各接続部材の連結される長さをデッキ材の横幅に応じて可変できるように連結されており、デッキ材の横幅寸法に応じて、複数個の接続部材を、雄形突起と雌形凹部との間隔を調整して連結配列し、連結された接続部材の基板上に突出する係止辺の間に、デッキ材の両側縁の凹溝を係合して、デッキ材を配列固定することを特徴としている。   As a specific means for that purpose, the present invention is arranged such that a plurality of deck materials arranged in parallel and constituting a floor surface are connected to each other in a direction perpendicular to the length direction of these deck materials, and the deck is arranged on the upper surface thereof. A plurality of connecting members for arranging and fixing the materials, the connecting members being a substrate having a length for mounting the lateral width of the deck material, and a female recess recessed in the substrate And a male protrusion projecting on the front end side of the substrate, and a locking side that engages with the concave groove on the deck material side edge projecting on the substrate between the female recess and the male protrusion. The female recess and the male projection are connected to each other by connecting the male projection of the connecting member adjacent to the female recess of one connection member along the length direction of the substrate. The connected length of the members can be changed according to the width of the deck material. According to the law, a plurality of connecting members are connected and arranged by adjusting the distance between the male projection and the female recess, and the deck material is interposed between the locking sides protruding on the substrate of the connected connecting members. The deck material is arranged and fixed by engaging the concave grooves on both side edges.

接続部材の基板に設けられる雌形凹部は、基板の長さ方向に沿った内側面に複数の異なる係合位置で、隣接する他の接続部材の雄形突起を嵌合係止できるような複数個の係止段部を有していて、雄形突起は、隣接する他の接続部材の雌形凹部の各係止段部に係合し得るような長さを有していることが好ましい。   A plurality of female recesses provided on the board of the connecting member can be fitted and locked with male projections of other adjacent connecting members at a plurality of different engaging positions on the inner surface along the length direction of the board. It is preferable that the male protrusion has a length that can be engaged with each locking step of the female concave portion of another adjacent connecting member. .

接続部材の基板先端側に突設される雄形突起は、上面が基板の表面と同じ高さであって、肉厚が基板の肉厚よりも薄く形成されていて、突起の長さ方向に沿って複数個の係止孔が間隔をおいて開設されており、基板に設けられる雌形凹部の下面の一端には雌形凹部の補強辺が設けられていて、この補強辺に、隣接する他の接続部材における雄形突起の係止孔のうちのいずれかと係合する、係止突起が設けられている   The male projection that protrudes from the front end of the connection member has a top surface that is the same height as the surface of the substrate, and is thinner than the thickness of the substrate. A plurality of locking holes are provided at intervals, and a reinforcing side of the female concave portion is provided at one end of the lower surface of the female concave portion provided in the substrate, and is adjacent to the reinforcing side. A locking projection is provided to engage with one of the locking holes of the male projection in the other connecting member.

デッキ材の側縁の凹溝と係合する基板上の係止辺が、雌形凹部と雄形突起との間における基板の上面両側部分に、基板の長さ方向と直交する向きで、互いに間隔をおいて突設された一対のウェブと、これらのウェブの上端に設けられた両側に案内傾斜面を有するフランジとから構成することが好ましい。   Locking sides on the board that engage with the grooves on the side edges of the deck material are located on both sides of the upper surface of the board between the female recess and the male projection in a direction perpendicular to the length direction of the board. It is preferable to configure a pair of webs protruding at intervals and flanges having guide inclined surfaces on both sides provided at the upper ends of these webs.

接続部材を根太上に固定する手段としては、基板上に設けられる一対の係止辺間に、基板上面の肉厚を薄くした固定部を設け、この固定部に基板を根太上に固定するためのネジ止め孔を有しているような構造とすることが好ましい。   As a means for fixing the connecting member on the joist, a fixing portion having a thin upper surface is provided between a pair of locking sides provided on the substrate, and the board is fixed to the joist on the fixing portion. It is preferable that the structure has a screw hole.

また，複数個の接続部材を互いに連結する態様としては、基準となる長さの基板からなる基準形接続部材を相互に連結してもよく、また、基準形接続部材と、この基準形接続部材よりも長さの大きい長形接続部材とを相互に連結するようにしてもよい。   In addition, as a mode of connecting a plurality of connecting members to each other, a reference connecting member made of a substrate having a reference length may be connected to each other, and the reference connecting member and the reference connecting member. A long connecting member having a longer length may be coupled to each other.

本発明のデッキ構造は、基板内に雌形凹部、基板の先端に雄形突起を設けて、一方の接続部材の雌形凹部に対して隣接する接続部材の雄形突起を、基板の長さ方向に沿って連結する構造としたので、雌形凹部に係合される雄形突起の係止位置を複数箇所に可変調節することができ、その結果、互いに連結される一対の接続部材の上にそれぞれ横幅の異なる複数種類のデッキ材を係合固定することができる。   In the deck structure of the present invention, a female concave portion is provided in the substrate and a male protrusion is provided at the tip of the substrate, and the male protrusion of the connecting member adjacent to the female concave portion of one connecting member is provided with the length of the substrate.

It is possible to engage and fix a plurality of types of deck materials having different widths.

また、連結される一対の接続部材は、互いに同じ長さからなる基準形の基板を連結した場合でも、雌形凹部と雄形突起との係合位置を変えることで、その上に横幅の異なる複数のデッキ材を固定することができるが、互いに連結される一対の接続部材のうち、いずれか一方の接続部材の基板の長さを、基準となる他方の接続部材の基板よりも長くしておくことで、雌形凹部と雄形突起との係合される長さをさらに可変することができ、別の大きな横幅のデッキ材を係合固定することができる。   In addition, even when a pair of connecting members to be connected is connected to a reference board having the same length, the width of the connecting member is changed by changing the engagement position between the female recess and the male protrusion. A plurality of deck materials can be fixed, but the length of the board of either one of the pair of connecting members connected to each other is longer than the board of the other connecting member serving as a reference. In this case, the length of engagement between the female recess and the male protrusion can be further varied, and another large lateral deck material can be engaged and fixed.

また、このデッキ材構造では、接続部材を順次連結したのちに、それぞれのデッキ材を、連結された一対の接続部材の継ぎ目上に配列した状態で、両方の接続部材における係止辺の間に上から落とし込めばよいので、デッキ材の取付け施工が簡単で能率的に行えるとともに、各デッキ材が接続部材の継ぎ目上で配列されることにより、デッキ材を安定よく配列固定することができる。   Further, in this deck material structure, after sequentially connecting the connection members, the respective deck materials are arranged on the joints of the pair of connected connection members, and between the locking edges of both connection members. Since the deck material can be dropped from above, the deck material can be easily and efficiently installed, and the deck materials can be arranged and fixed stably on the joints of the connecting members.

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接続部材として、２種類の、基準となる長さの基板と、この基準形の基板よりも長さの大きい基板とを互いに連結させることで、横幅の短いデッキ材から横幅の広いデッキ材まで複数種類のデッキ材を係合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 connecting member for fixing the deck material, two kinds of base boards having a reference length and a board having a length longer than the base board are coupled to each other. Thus, it is preferable to have a structure capable of engaging and fixing a plurality of types of deck materials from a deck material having a short width to a deck material having a wide width.
