【考案の詳細な説明】
この考案は、ロツクボルト工法において、削口
した孔内の一定長さで定着剤を止めたり、削口し
た孔径の中心近くにボルトを位置させ、定着剤を
固結させることが可能なロツクボルトに関するも
のである。[Detailed explanation of the invention] This invention uses the Lock Bolt method to stop the fixative at a certain length within the drilled hole, or to solidify the fixative by positioning the bolt near the center of the drilled hole. This relates to a lock bolt that can be used.
即ち、第１図に示す如く削口孔と同一直径を有
する弾性板１と、弾性板１の直径よりやゝ小さな
直径よりなる硬直性を有する補助板２とを組み合
わせて、定着剤流出防止用の円板３を形成し、こ
の円板３をロツクボルト４に円板３とロツクボル
ト４の軸心を一致させて着脱可能或は固定して取
りつけたものである。 That is, as shown in FIG. 1, an elastic plate 1 having the same diameter as the drilling hole and a rigid auxiliary plate 2 having a diameter slightly smaller than the diameter of the elastic plate 1 are combined to prevent the fixer from flowing out. This disc 3 is detachably or fixedly attached to a lock bolt 4 with the axes of the disc 3 and the lock bolt 4 aligned.

を提供出来たのである。 Since the lock bolt of this invention has such a structure, even if the inner circumferential surface of the drilled hole has some unevenness, if the elastic plate 1 is made of soft rubber, etc., the lock bolt 4 can be rotated to drill the hole. For example, when crushing a capsule containing a fixing agent, the lock bolt 4 can be inserted into the depths of the lock bolt 4 without obstructing its entrance.
At the position where the lock bolt 4 is stopped from entering, the outer periphery of the elastic plate 1 closes the inner surface of the hole wall, thereby preventing the fixing agent from flowing out. Further, even if the elastic plate 1 tries to deform due to the outflow of the fixing agent, the elastic plate 1 will not be deformed because the auxiliary plate 2, which has rigidity and is made of, for example, an iron plate, is attached to the elastic plate 1 in combination.
Further, since the diameter of the auxiliary plate 2 is slightly smaller than that of the elastic plate 1, the auxiliary plate 2 will not get stuck on the hole wall surface and become an obstacle when the lock bolt 4 enters. Furthermore, since the auxiliary plate 2 has rigidity and is installed in alignment with the axis of the lock bolt, the lock bolt can be positioned near the center of the hole diameter using the auxiliary plate 2, and the fixing agent can be applied evenly around the auxiliary plate 2. This made it possible to solidify the bolts and provide a lock bolt with good construction stability.
