Further, the upper connecting joist 10 is formed with a floor material cover mounting portion 12 by extending the upper part of the left and right side surfaces to the left and right sides, and the floor material cover 8a is screwed to the floor material cover mounting portion 12 from above. It is.

次に、本発明の床１の施工手順について説明する。まず、建物の外壁Ｘに根太掛け４を固定する。そして、根太掛け４の左右両端に躯体方立２ｂ，２ｂを取り付け、外壁Ｘと固定する。外壁Ｘから間隔をあけて前側に配置する柱２ａ及び束柱２ｃには、前桁３をネジ止めし、躯体方立２ｂと柱２ａの間には、妻桁５をネジ止めする。次いで、左右中間位置において、連結根太７を前桁３と根太掛け４の間に架設する。連結根太７は、まず下連結根太２０を前桁３、根太掛け４及び大引き９に固定する。下連結根太２０は、連結部２１と前桁３及び根太掛け４の支持部３ａ，４ａ並びに大引き９の上面が重なり合う位置において、左右両側の連結部２１，２１を上方からネジ止めする。次に、上連結根太１０を下連結根太２０の上部に被せ、両側壁を左右方向からネジ止めして上連結根太１０と下連結根太２０を一体とする。前桁３と根太掛け４の間に根太６，６…をネジ止めした後、妻桁５と連結根太７間の根太６上に床材８を敷設していく。床材８は、上連結根太１０の床材支持部１１の上に敷設し、上方からネジ止めする。そして床材８と、上連結根太１０、前桁３及び妻桁５との隙間を床材カバー８ａによって覆う。   Next, the construction procedure of the floor 1 of the present invention will be described. First, the joist 4 is fixed to the outer wall X of the building. Then, the frame verticals 2 b and 2 b are attached to the left and right ends of the joist hook 4 and fixed to the outer wall X. The front girder 3 is screwed to the pillar 2a and the bundle pillar 2c arranged on the front side with a space from the outer wall X, and the end girder 5 is screwed between the frame stand 2b and the pillar 2a. Next, the connecting joists 7 are installed between the front girders 3 and the joists 4 at the left and right intermediate positions. The connection joist 7 first fixes the lower connection joist 20 to the front girder 3, the joist hook 4 and the large pull 9. The lower connecting joist 20 screws the connecting portions 21 and 21 on both the left and right sides from above at the positions where the connecting portion 21 and the support portions 3a and 4a of the front girder 3 and joist hook 4 and the upper surface of the large pull 9 overlap. Next, the upper connection joist 10 is put on the upper part of the lower connection joist 20, the both side walls are screwed from the left and right directions, and the upper connection joist 10 and the lower connection joist 20 are integrated. After the joists 6, 6... Are screwed between the front girders 3 and the joists 4, the flooring 8 is laid on the joists 6 between the girder 5 and the connecting joists 7. The flooring 8 is laid on the flooring support 11 of the upper connecting joist 10 and is screwed from above. And the clearance gap between the flooring 8, and the upper connection joist 10, the front girder 3, and the end girder 5 is covered with the flooring cover 8a.

このように構成した床１によれば、連結根太７は、上連結根太１０と下連結根太２０からなり、上連結根太１０は左右両側に床材支持部１１を有するため、下連結根太２０を前桁３、根太掛け４、大引き９へ連結する際に、床材支持部１１が邪魔にならず施工性に優れる。また、連結根太７を取り付けるために他の部品を用いる必要がないため、従来よりもコストを抑えることができる。
下連結根太２０は、連結部２１が上連結根太１０の床材支持部１１の下方に位置するので、連結根太７は左右方向の幅を小さくすることが可能となり、コストを抑えることができる。そして、上連結根太１０と下連結根太２０は、左右の側壁において左右方向にネジ止めしてあるため、ネジが外観から見えず、意匠性が良い。また、下連結根太２０の連結部２１は前桁３、根太掛け４、大引き９に、上下方向にネジ止めできるため、左右方向のネジ止めよりも作業が容易で施工性に優れる。 According to the floor 1 configured as described above, the connecting joist 7 is composed of an upper connecting joist 10 and a lower connecting joist 20, and the upper connecting joist 10 has the floor material support portions 11 on both the left and right sides. When connecting to the front girder 3, the joist 4 and the large pull 9, the floor material support 11 does not get in the way and is excellent in workability. Moreover, since it is not necessary to use another component in order to attach the connection joist 7, cost can be suppressed compared with the past.
Since the connecting part 21 is located below the floor material support part 11 of the upper connecting joist 10 in the lower connecting joist 20, the connecting joist 7 can be reduced in width in the left-right direction, and the cost can be reduced. And since the upper connection joist 10 and the lower connection joist 20 are screwed in the left-right direction in the left and right side walls, the screw is not visible from the appearance, and the design is good. Moreover, since the connection part 21 of the lower connection joist 20 can be screwed to the front girder 3, the joist hook 4 and the large pull 9 in the vertical direction, the work is easier and the workability is superior to the screwing in the horizontal direction.

本発明は、上記の実施形態に限定されない。前後左右いかなる寸法の床にも適用可能であり、寸法に合わせて大引きの有無や束柱の数を適宜決定できる。また、用途としてはデッキやテラス等の簡易構造物の床に限定されるものではなく、様々な構造物の床として広く適用可能である。   The present invention is not limited to the above embodiment. The present invention can be applied to a floor of any size, front, rear, left and right, and the presence or absence of overdrawing and the number of bundle pillars can be appropriately determined according to the size. Further, the use is not limited to a floor of a simple structure such as a deck or a terrace, but can be widely applied as a floor of various structures.
