で、ばらつきのない安定した固着力を得ることが
できる。(Function of the invention) According to this invention, the tread can be fixed to the stringer simply by inserting the mounting rod into a deep hole filled with a hardening agent, and workability is significantly improved. Furthermore, since the mounting rod is fixed by the hardening agent, a stable fixing force without variation can be obtained.
以下この考案の実施例を図面に基いて説明す
る。 Examples of this invention will be described below with reference to the drawings.

踏板１の下部に長ナツト６が埋設してあり、該
長ナツト６の一端は踏板１の下面に開口してお
り、他端には補強板７がボルト８によつて固定し
てある。前記長ナツト６の開口側には固定杆２と
してのボルトの先端部が螺合させてある。(Example) A long nut 6 is embedded in the lower part of the footboard 1, one end of the long nut 6 is open at the bottom surface of the footboard 1, and a reinforcing plate 7 is fixed to the other end with bolts 8. There is. The tip of a bolt serving as the fixing rod 2 is screwed into the open side of the long nut 6.
前記固定杆２の基端側はささら桁３の上面に開
校した深穴４内に挿入してあると共に、前記固定
杆２は深穴４へ充填された硬化剤５によつてささ

嵌装されたインサートであつて、内壁には螺旋状
の凸条１０ａが形成してある。 The base end side of the fixing rod 2 is inserted into a deep hole 4 opened on the upper surface of the stringer 3, and the fixing rod 2 is hardened into the stringer 3 by the hardening agent 5 filled into the deep hole 4. It's fixed. In the figure, 2a is a bolt head as a protrusion, 9 is a tightening nut, 10 is an insert fitted into the deep hole 4, and a spiral protrusion 10a is formed on the inner wall.
この実施例の装置を組み立てるには、踏板１の
長ナツト６に固定杆（ボルト）２を螺合し、次い
で予め未硬化の硬化剤５を充填した深穴３内へ固
定杆２を挿入し、前記硬化剤５の硬化を待てばよ
い。 To assemble the device of this embodiment, the fixing rod 2 is screwed onto the long nut 6 of the treadle 1, and then the fixing rod 2 is inserted into the deep hole 3 filled with an uncured hardening agent 5. , it is sufficient to wait for the hardening agent 5 to harden.
この実施例によれば、固定杆としてボルトを用
い、踏板１へ着脱自在に螺合固定したので、固定
杆は現場で取付けることができる。然して踏板は
運搬・保管時に突起が存在せず、積み重ね可能で
あり、取扱が容易である。 According to this embodiment, bolts are used as the fixing rods and are removably screwed and fixed to the footboard 1, so that the fixing rods can be installed on site. However, the treadle does not have any protrusions during transportation and storage, can be stacked, and is easy to handle.
またこの実施例ではボルトを固定する長ナツト
８に補強板７を取付けたので、補強板７の周縁部
７ａが掛止部として働き、上下方向の力に対して
大きな耐性を得ることができる。 Further, in this embodiment, since the reinforcing plate 7 is attached to the long nut 8 for fixing the bolt, the peripheral edge 7a of the reinforcing plate 7 acts as a hooking part, and it is possible to obtain a large resistance against vertical forces.
尚、補強板７は溶着してもよいが、ボルト固定
の方が大きな強度を得ることができる。 Note that the reinforcing plate 7 may be welded, but greater strength can be obtained by fixing it with bolts.
更にボルト頭２ａが掛止部として働き、固定杆
の脱抜が防止される。 Furthermore, the bolt head 2a acts as a hook, preventing the fixing rod from coming off.
（考案の効果）
この考案によれば、硬化剤を充填した深穴内へ
固定杆を挿入するのみで、踏板をささら桁に固定
できるので、作業が容易である。(Effects of the invention) According to this invention, the treadle can be fixed to the stringer simply by inserting the fixing rod into a deep hole filled with a hardening agent, making the work easy.
また硬化剤の選択、固定杆の設計が同一であれ
ば、何人が作業を行つても同一強度で固定するこ
とができ、仕上り強度の信頼性が高い等の硬化が
ある。 Furthermore, if the selection of the hardening agent and the design of the fixing rod are the same, it can be fixed with the same strength no matter how many people work on it, and the finished strength is highly reliable.
