【考案の詳細な説明】 この考案は階段の側げたと踏み板との締結などに使用さ
れる木質部材連結構造に関するものである。[Detailed Description of the Invention] This invention relates to a wooden member connection structure used to connect the side beams of stairs and treads.

従来の階段における側げたと踏み板の締結はビス等によ
り行なわれているが、その締結程度が弱いためにビス等
にゆるみが生じ、踏み板を踏んだときに踏み鳴りが発生
するという問題を有していた。In conventional stairs, the side girders and the treads are fastened using screws, etc., but because the level of fastening is weak, the screws, etc. become loose, which causes a tread noise when stepping on the treads. was.

したがって、この考案の目的は、木質部材の締結を強固
に行なうことができる木質部材連結構造を提供すること
である。Therefore, an object of this invention is to provide a wooden member connecting structure that can firmly connect wooden members.

この考案の一実施例を第１図ないし第５図に示す。An embodiment of this invention is shown in FIGS. 1 to 5.

すなわち、この木質部材連結構造は、第１図に示すよう

めっき鋼板４と、この亜鉛めっき鋼板４の表面に配設さ
れる爪付き座金５と、踏み板２内に埋設されたナツト６
と、亜鉛めっき鋼板４および爪付き座金５を貫通してナ
ツト６に螺着するボルト７とを備えたものである。That is, this wooden member connection structure is used for the fastening part between the side beam 1 and the tread 2 in a staircase, as shown in FIG. 1, and as shown in FIGS. A rectangular galvanized steel plate 4 that is disposed in a non-rotating state in a rectangular recess 3 provided in the rectangular recess 3 and has a bolt insertion hole (not shown) in the center, and a claw disposed on the surface of this galvanized steel plate 4. a washer 5 and a nut 6 embedded in the footboard 2
and a bolt 7 that passes through the galvanized steel plate 4 and the claw washer 5 and is screwed into the nut 6.

爪付き座金５は、第４図に示すように、その表面が鋸歯
状凹凸面５ａに形成されるとともに、その裏面に、第５
図に示すように放射状に伸びて突設した４本の爪５ｂを
有し、その中央部にはボルト挿通孔５ｃを形成している
。As shown in FIG. 4, the claw washer 5 has a serrated uneven surface 5a on its surface, and a fifth groove on its back surface.
As shown in the figure, it has four protruding claws 5b extending radially, and a bolt insertion hole 5c is formed in the center thereof.

なお、この爪５ｂは、亜鉛めっき鋼板４よりも硬質の金
属材料で形成されることが望ましい。Note that this claw 5b is desirably made of a metal material harder than the galvanized steel plate 4.

ボルト７は、その座面７ａが、爪付き座金５の鋸歯状凹
凸面５ａと係合するように、同じく鋸歯状の凹凸面に形
成されている。The bolt 7 is also formed into a serrated uneven surface so that its seat surface 7a engages with the serrated uneven surface 5a of the claw washer 5.

つぎに、施工手順を説明する。Next, the construction procedure will be explained.

すなわち、第２図および第３図に示すように、亜鉛めっ
き鋼板４を側げた１の角形凹部３内に嵌入し、この亜鉛
めっき鋼板４の表面に爪付き座金５の爪５ｂを当接させ
、その状態でボルト７の軸部７ｂを爪付き座金５および
亜鉛めっき鋼板４のそれぞれのボルト挿通孔５Ｃ並びに
側げた１のボルト挿通孔１ａに順次挿通して踏み板２内
に埋設したナツト６に螺着する。That is, as shown in FIGS. 2 and 3, a galvanized steel plate 4 is fitted into the rectangular recess 3 on the side, and the claws 5b of the claw washer 5 are brought into contact with the surface of the galvanized steel plate 4. In this state, the shaft part 7b of the bolt 7 is sequentially inserted into the bolt insertion hole 5C of the claw washer 5 and the galvanized steel plate 4, and the bolt insertion hole 1a of the side 1, and then inserted into the nut 6 buried in the footboard 2. Screw on.

この場合、ボルト７の締め付は回転により、ボルト７の
座面７ａが爪付き座金５の鋸歯状凹凸面５ａと係合する
ため、爪付き座金５も同時に回転しながら亜鉛めっき鋼
板４に向けて押圧され、一方、亜鉛めっき鋼板４は角形
凹部３内に嵌合されているためボルト７の回転によって
も回転せず、したがってこのボルト７の締め付けを回転
不可能な程度まで行なうことにより、爪付き座金５の爪
５ｂを亜鉛めっき鋼板４に食い込ませることができる。In this case, the bolt 7 is tightened by rotation so that the bearing surface 7a of the bolt 7 engages with the serrated uneven surface 5a of the claw washer 5, so that the claw washer 5 is also rotated at the same time and directed toward the galvanized steel plate 4. On the other hand, since the galvanized steel plate 4 is fitted into the rectangular recess 3, it does not rotate even when the bolt 7 rotates, so by tightening the bolt 7 to the extent that it cannot rotate, the claw The claw 5b of the washer 5 can bite into the galvanized steel plate 4.

このように、側げた１の角形凹部３内に角形亜鉛めつぎ

げた１と踏み板２に対して確実に回り止め（ゆるみ止め
）して、側げた１と踏み板２を強固に緊結できるため、
踏み板２を踏んでも踏み鳴りを生じない。In this way, since the rectangular galvanized steel plate 4 is fitted into the rectangular recess 3 of the side arm 1, the galvanized steel plate 4 can be reliably prevented from rotating relative to the side arm 1 despite the connection between the wooden member and the metal member. Moreover, since the claws 5b of the claw washer 5 are bitten into the surface of the galvanized steel plate 4, and both the claws 5b and the galvanized steel plate 4 are made of metal members, the claw washer 5 can be attached to the galvanized steel plate 4. The rotation can be reliably stopped by
Furthermore, since the uneven seat surface 7a of the bolt 7 is engaged with the uneven surface 5a of the claw washer 5, the bolt 7 can be reliably prevented from rotating relative to the claw washer 5, and the shaft portion of the bolt 7 can be inserted into the embedded nut 6. Since it is screwed in, the bolt 7 and the footboard 2 can be connected reliably, and in the end, the above mechanism securely prevents the bolt 7 from rotating (loosening) with respect to the sidewall 1 and the footboard 2, and the sidewall 1 and the footboard 2 are connected. Because it can be tightly bonded,
Even if the footboard 2 is stepped on, no stepping sound is generated.

また、爪５ｂが亜鉛めっき鋼板４にのみ食い込んで側げ
た１には食い込まないため、側げた１の損傷も防止でき
る。Furthermore, since the claws 5b bite only into the galvanized steel plate 4 and not into the side beams 1, damage to the side beams 1 can also be prevented.

さらに、ボルト７のボルト頭が角形凹部３内に嵌入する
ため、ボルト頭が外部から目立たなくなって美感に優れ
るとともに、ボルト頭に衣服等を引っ掛ける危険もない
。Furthermore, since the bolt head of the bolt 7 fits into the rectangular recess 3, the bolt head is not noticeable from the outside, resulting in an excellent aesthetic appearance, and there is no danger of clothing or the like getting caught on the bolt head.

なお、上記実施例においては、ボルト７を用いたが、こ
れに限らず、ビス等の他のねじ部品でもよい。Although the bolt 7 is used in the above embodiment, the present invention is not limited to this, and other threaded parts such as screws may be used.

ができるという効果を有する。As described above, the wooden member connecting structure of this invention includes a first wooden connecting member with an embedded nut embedded in the surface, a non-circular recess on the surface, and a first screw insertion hole extending from the bottom of the recess to the back surface. a second wooden connecting member having a hole therein, the back surface thereof facing the surface of the first wooden connecting member, and a screw insertion hole aligned with the embedded nut; a non-circular metal plate with a second screw insertion hole provided in the center aligned with the first screw insertion hole; a claw washer with a third screw insertion hole provided at the center in contact with the surface of the plate aligned with the second screw insertion hole; By screwing into the embedded nut through the second and first screw insertion holes, the claw washer is rotated together with the uneven bearing surface that fits into the uneven surface of the claw washer, and the claw is inserted into the non-circular shape. Since it includes a screw part that bites into the surface of the metal plate, it has the effect of making it possible to firmly fasten the wooden members.
