【考案の詳細な説明】
（技術分野）
本考案は、建物の上下階を連絡する階段に於い
て桁材に段板を固定する装置に関する。[Detailed Description of the Invention] (Technical Field) The present invention relates to a device for fixing treads to girders in a staircase connecting upper and lower floors of a building.
（従来技術及び問題点）
桁材に段板を取付けるものとしては従来から
種々の取付構造及び装置が提案されている。(Prior Art and Problems) Various mounting structures and devices have been proposed for attaching step plates to girders.
例えば桁材側面に掘込溝を設け、この掘込溝に
段板を嵌着させるものや、桁材に受材を設け、こ
の受材上面に形成した蟻突条を段板の下面に設け
た蟻溝に嵌入して取付けるもの等である。 For example, a groove may be provided on the side surface of the girder material and the tier plate may be fitted into the groove, or a receiving material may be provided on the girder material and dovetail ridges formed on the upper surface of the receiving material may be placed on the bottom surface of the tier plate. It is installed by fitting into a dovetail groove.
しかし前者の掘込溝によつて段板を取付ける場
合は、掘込溝の施工が容易でなく、しかも掘込溝
と段板の隙間等を処理するに多くの現場作業を要
する。 However, in the case of the former method, in which the steps are attached by means of dug grooves, the construction of the dug grooves is not easy, and moreover, it requires a lot of on-site work to clear the gaps between the dug grooves and the steps.
一方後者に於いては、蟻溝に蟻突条を嵌入させ
るので、取付作業は容易なものの蟻溝と蟻突条の
相互位置が一旦狂うと調整施工が大幅にかかる
等、何れも現場に於ける施工性を低下させる問題
点を有している。 On the other hand, in the latter case, the dovetail ridges are inserted into the dovetail grooves, so the installation work is easy, but once the mutual positions of the dovetail grooves and the dovetail ridges are out of alignment, it takes a lot of adjustment work. However, it has the problem of reducing workability.
（問題点を解決する為の手段）
本考案は上記問題点に鑑み案出されたもので、
段板を受材上にスライドさせて段板の先端面と桁
材とをダボ接合するとともに、受材の上面に取付

ができる。 That is, in this fixing device, the leading end of the step board 3 is dowel-jointed to the girder 1, and the center or rear end of the step board 3 is connected to the step board 3 by fitting the fixing fitting 14 and the engaging metal fitting 22. It is possible to ensure a stable fixed state without floating or falling off. Also, tap the tip end surface 31 of the step plate 3 to remove the girder material 1.
By releasing the dowel connection, the protrusions 17, 17 of the fixing metal fitting 14 can be removed from the engaging grooves 25, 25 of the engaging metal fitting 22 toward the front opening side, contrary to the above.
（効果）
以上説明した様に本考案の固定装置によれば、
段板を受材上で押し込む作業によつて段板の
先端部及び中央若しくは後端部が一体的に取付

タツチ式に行なえる。(Effects) As explained above, according to the fixing device of the present invention, the leading end and center or rear end of the tier are integrally attached and fixed by pushing the tier onto the receiving material. In other words, the step board fixing work can be done in a one-touch manner.
予め段板に接合金具を取付け、更に受材に固
定金具を取付けておけば、現場での取付精度に
狂いがなく、又狂いが生じても十分吸収出来る
ので取付作業が至つて簡易となる。 By attaching the joining fittings to the step boards in advance and further attaching the fixing fittings to the receiving material, there will be no deviation in the installation accuracy on site, and even if deviations occur, they can be sufficiently absorbed, making the installation work extremely simple.
更に段板の先端部を叩き出しダボ接合を解除
すれば、段板は容易に脱着出来るので、段板自
体の交換或いは取外し等メンテナンス作業にお
いて極めて好適なものとなる。 Furthermore, if the tip of the step board is knocked out and the dowel joint is released, the step board can be easily attached and detached, making it extremely suitable for maintenance work such as replacing or removing the step board itself.
段板と桁材とのダボ接合及び段板と受材を固
定する各金具は外部に露出されない為、階段全
体の美観を損うこともない。 Since the dowel joints between the tiers and the girders and the metal fittings that fix the tiers and the support members are not exposed to the outside, the aesthetic appearance of the entire staircase is not impaired.
等実用的効果を発揮できる。It can have practical effects such as
