【考案の詳細な説明】 〔考案の目的〕 （産業上の利用分野） この考案は階段の踏板の両端部を階段の側板に大入れ接
合（材の断面を他材の表面内に差し込んで接合するこ
と）する場合、階段の踏板の裏面と大入れ溝との隙間に
打ち込む踏板拘止用くさびに関するものである。[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) This invention inserts both ends of the step plate of the stairs into the side plates of the stairs and inserts them (insert the cross section of the material into the surface of another material and join them). The present invention relates to a wedge for restraining a tread, which is driven into the gap between the rear surface of the tread of the stairs and the large insertion groove.
（従来の技術） 従来、階段の両側面の大入れ溝に挿嵌した踏板を拘止す
るため、踏板の裏面と大入れ溝との間にくさびを打ち込
み、これを釘着していた。(Prior Art) Conventionally, in order to lock the treads inserted into the large insertion grooves on both side surfaces of the stairs, a wedge was driven between the rear surface of the tread and the large insertion groove and nailed.
（考案が解決しようとする問題点） しかし、くさびを釘着する場合、釘が打ち込まれる位置
は、踏板裏面のすぐ傍となる為、その踏板の裏面が邪魔
になって、鉄鎚で釘を打ちにくく、又、その釘は大入れ
溝の底に向けて打ち込まれるので、くさびの肉厚に対し
て、釘を受ける側板の肉厚が相対的に小さくなって、釘
接合の耐力低下を招いたり、くさびの幅に対して釘のヘ
リアキ幅が不足し、くさびのせん断破壊を招いていた。(Problems to be solved by the device) However, when a wedge is nailed, the position where the nail is driven is right next to the back surface of the tread, so the back surface of the tread interferes and the nail is used to remove the nail. It is hard to hit, and because the nail is driven toward the bottom of the large insertion groove, the wall thickness of the side plate that receives the nail is relatively smaller than the wall thickness of the wedge, which leads to a decrease in the yield strength of the nail joint. The width of the nail was insufficient for the wedge and the width of the wedge, resulting in shear failure of the wedge.
（問題点を解決するための手段） そこで、この考案は上記の欠点を除去するため、第１図

板拘止用くさび（１）を提供しようとするものである。(Means for Solving the Problems) Therefore, in order to eliminate the above-mentioned drawbacks, the present invention provides an angled tread restraint wedge (1) in FIG. 1 with synthetic resin or wood as a material. A wedge (1) for restraining a tread, characterized in that the wedge (1) for restraining a tread is a wedge (2) having a shape in which the thickness of one piece of the wedge (1) for restraining the tread is cut off by inclining in the longitudinal direction. Is what you are trying to do.

ない。(Operation) Wedge for restraining tread (1) configured as described above
Insert the wedge pieces (3) and (3 ') of (1') between the rear surface of the tread (4) and the large insertion groove (5), and apply a strong external force to further push in to expose the outside. The surface of the tread (4) is brought into close contact with the ridgeline of the insertion groove (5) to lock the tread (4) on the side plate (6) of the stairs. At this time, the wedge pieces (2) (2) The unevenness (3) for preventing slippage provided on the surface of ′) bites into the back surface of the tread (4) and the pushed tread restraining wedges (1) (1 ′) do not return.

（４）の裏面が邪魔になることがなく、しかも、釘
（８）を受ける側板（６）の肉厚を最大限に利用して釘
の一面せん断耐力の向上を図れる。The wedges (1) (1 ') for restraining the treads that have been pushed in have the other piece (7) formed in an angle shape directed toward the lower side of the large insertion groove (5) and on the surface of the side plate (6). Since it is installed, the heliaki (e 2 ) can be appropriately attached to the found surface of the other piece (7).
And, nails (8) are driven ahead of Hasashiki (e 1 ). In this position, the back surface of the tread (4) does not get in the way when the nail (8) is driven in, and moreover, the thickness of the side plate (6) for receiving the nail (8) is utilized to the maximum, and one surface of the nail is The shear strength can be improved.
尚、他片（７）の見付け面の釘（８）を打つ箇所に、予
め錐穴（９）を穿設しておいても良い。Incidentally, a conical hole (9) may be preliminarily formed in the other surface of the other piece (7) where the nail (8) is hit.

（１′）で対処できる。In the tread wedge (1 '), when trying to hook both ends of the tread (4) to the left and right side plates (6), an angled tread wedge (1) is used. , The relationship between the protruding direction of the wedge piece (2) with respect to the other piece (7) and the slope thereof provides usability in the left-right direction, so that the wedge piece (2 ′) like the tether restraint wedge (1 ′). ) Is formed in a flange shape on the left and right sides of the other piece (7), one of the wedges (1 ') for restraining the tread can be used for either convenience.
側板（６）に穿設する溝（10）は、蹴込み板を大入れす

止用くさび（１′）は踏板（４）と蹴込み板とに囲まれ
て隠れ、階段が仕上がった段階では外部に露呈しない。The groove (10) formed in the side plate (6) is a groove (10) into which the riser plate is largely inserted, and the tread plate restraining wedge (1) or the tread plate restraining wedge (1 ') is the tread plate (4). ) And a riser board, it hides and is not exposed to the outside when the stairs are finished.
これにより、踏板拘止用くさびの側板への釘着が容易と
なり、側板の最大肉厚部分に釘を打ち込めるので、踏板
の釘接合耐力の増大が達成され、又、踏板拘止用くさび

に行なえるばかりか、荷重に抵抗して、くさびのねじ
れ、ずれ、圧潰、脱落等の心配がなくなるという数々の
多大な効果を奏する。As a result, it becomes easier to attach the tread wedge to the side plate, and the nail can be driven into the thickest part of the side plate, so that the nail joint proof strength of the tread is increased, and the tether wedge has a cross section. Since it has an angled shape, it not only makes it easy to hammer in the wedge, but also resists the load and has a number of great effects of eliminating the risk of twisting, slipping, crushing, or falling of the wedge.
