Abstract

To provide a J joint metal preventing thinner thickness of lumber, difficulty of processing, cracking/twisting/bending of lumber, retightening when the lumber becomes thinner from being disabled, to make required processing of the lumber and a number of screws to be applied unnecessary because of interference of structural members to each other.SOLUTION: A J joint metal allows strength of lumber itself to remain to the maximum because thickness of the lumber remains to the maximum, a suppression effect for natural twisting of the lumber to be improved by inserting the lumber in a square steel-box-shaped cylindrical part 6 of metal, and a strong strength joint part to be realized by fastening and pulling nut from a main box 4 in a rear side. Further, the joint metal is applicable to various lumber by changing length/size/direction of the square steel-box-shaped cylindrical part 6 and a strap bolt 2. Main structural parts, such as bases/columns/girders/beams/braces, are jointed without loss by adding plates 10 for fixing the braces to the J joint metal to be integrated and allows time of lumber processing steps to be shortened by preventing interference of other structural members upon installation of auxiliary lumber (such as furring).SELECTED DRAWING: Figure 2

Description

本発明は、木造在来工法建築物の基礎・柱・桁・梁・筋交いや、ＤＩＹ等でも使用する大小様々な木材（以下、総称して木材という）同士の多方向への接合部分に使用する金物、及び強固に接合するための簡単な木材加工方法で主要構造材に適した木材接合方法に関する。 The present invention is used for the foundations, pillars, girders, beams, streaks, and joints of various sizes of wood (hereinafter collectively referred to as wood) used in DIY, etc., in multiple directions. It relates to a wood joining method suitable for a main structural material by a simple wood processing method for firmly joining and a metal fitting to be used.

金物とピドリフトピンを使用する木材接合方法（特許文献１）は木材が痩せた時（必ず痩せる）、締め付け・引き寄せ・増し締めが不可能。更に、メスになる部分の木材を縦に割く加工を施す為、木材に負担がかかると考える。 従来の無垢材同士を接合するには、伝統的な大工職人の技術が良いと考える。しかし、近年は人工的な乾燥剤や集成材を多く用いているため、一例として、台形にオス・メスを加工するアリ継ぎなどでは、木材が割れ・欠けるなど破損し弱くなるのが現状。大黒柱も通し柱も大きな梁も使用しない傾向にある為、木材同士の接合部分は、筋交いなど他の構造材も含め、最も強度を保つ必要がある。しかし、現状では木材の材成に対し小さな仕口加工を施し、ボルトなどで補強や引き寄せを行う為、ボルトにナットを締め付けるために６ｃｍ×６ｃｍ×６ｃｍほどの大きな穴を木材に開ける必要がある。補強金物も、ホールダウンや羽子板金物では、木材の一片しか引き寄せる事が出来ず、閉めすぎによる木材の曲がりも問題となる。更に、筋交いなど構造材も様々な金物で補強はしているがその金物を付けるために、木材の肉厚を減らす様な加工が必要で大量のビスを打つことで、割れが生じ、弱らせている。 The wood joining method (Patent Document 1) that uses hardware and a pidri pin cannot be tightened, pulled, or retightened when the wood becomes thin (always thin). Furthermore, it is considered that the wood will be burdened because the wood of the female part is split vertically. I think that traditional carpenter's technique is good for joining conventional solid woods. However, in recent years, many artificial desiccants and laminated lumbers have been used, so as an example, in the case of ant splicing, which processes males and females into trapezoids, the current situation is that the wood is broken or chipped and becomes weak. Since there is a tendency not to use large black columns, through columns, or large beams, it is necessary to maintain the highest strength at the joints between timbers, including other structural materials such as braces. However, at present, it is necessary to make a large hole of about 6 cm x 6 cm x 6 cm in the wood in order to tighten the nut on the bolt because a small joint process is applied to the lumber material and reinforcement and pulling are performed with bolts. .. As for the reinforcing hardware, hole down and battledore can only attract a piece of wood, and bending of the wood due to over-closing is also a problem. In addition, structural materials such as braces are also reinforced with various hardware, but in order to attach the hardware, processing such as reducing the wall thickness of the wood is required, and by hitting a large number of screws, cracks occur and weaken. I'm letting you.

特開２００８−２０２３９２Japanese Patent Application Laid-Open No. 2008-20392

本発明は、接合しようとする木材の肉厚を最大限に残す上、折れ・割れ・ひねり・曲がりを解消すると共に、締め付け・引き寄せや、痩せた時の増し締めが可能になる木材接合方法を提供する。 The present invention provides a wood joining method that maximizes the thickness of the wood to be joined, eliminates breaks, cracks, twists, and bends, and enables tightening / pulling and retightening when thin. offer.

接合する木材とＪ接合金物の大きさは比例しており、様々な木材に使用できると共に、自然現象であるひねりや曲がりを抑制し、接合時の引き寄せや痩せた時の増し締めが可能になる。
木材の肉厚を最大限に残すため、木材加工方法は、木材の接続する断面から、羽子板（２）が入る最小限の穴（１２）を開ける。羽子板に対し、直行に固定ボルト（３）が通る最小限の穴（１３）を開ける。金物の四角形の鋼製箱状の筒（６）の部分が干渉する部分（７）を最小限でかぎ取るのみ。The size of the wood to be joined is proportional to the size of the J-joining hardware, and it can be used for various types of wood. It also suppresses twisting and bending, which are natural phenomena, and enables pulling at the time of joining and retightening at the time of thinning. ..
In order to leave the maximum wall thickness of the wood, the wood processing method is to make a minimum hole (12) for the battledore (2) from the connecting cross section of the wood. Make a minimum hole (13) in the battledore for the fixing bolt (3) to pass through in a straight line. Only the part (7) that interferes with the square steel box-shaped cylinder (6) of the hardware is scraped off at the minimum.

上記説明の通り、木材の肉厚が最大限に残るため、木材自体の強度を最大限に残し、金物の四角形の鋼製箱状の筒の部分（６）に木材を差し込むことで、木材の自然のひねりを防止効果が高まり、その裏側である主箱（４）から、ナット（９）で木材の中心に近い部分を締め付け引き寄せる事で、強い強度の接合部分が実現できる。更に四角形の鋼製箱状の筒の部分（６）と羽子板ボルト（２）の長さ・大きさ・方向を変更することで、様々な木材に対応できる。
Ｊ接合金物に筋交い固定用のプレート（１０）増設し、一体型にすることで基礎・柱・桁・梁・筋交いなどの主要構造部を無駄なく接合でき、付属の木材（胴縁など）設置時、他の構造金物との干渉を防ぎ、木材加工工程が短縮できる。As explained above, since the wall thickness of the wood remains at the maximum, the strength of the wood itself is left at the maximum, and the wood is inserted into the square steel box-shaped cylinder part (6) of the hardware to make the wood. The effect of preventing natural twisting is enhanced, and a strong strength joint can be realized by tightening and pulling the part near the center of the wood with the nut (9) from the main box (4) on the back side. Furthermore, by changing the length, size, and direction of the square steel box-shaped cylinder part (6) and the wing plate bolt (2), various types of wood can be used.
By adding a plate (10) for fixing the brace to the J-joining hardware and integrating it, the main structural parts such as the foundation, columns, girders, beams, and brace can be joined without waste, and the attached wood (further edge, etc.) is installed. At times, interference with other structural hardware can be prevented and the wood processing process can be shortened.
