Abstract: An anchor bolt (40) according to the present invention has a taper member (7) threadably engaged with the rod (4), and three or five abutment parts (12) fitted over the taper member (7). The taper member (7) has a cross section in a form of an equilateral triangle or pentagon, and three or five inclined surfaces (10) at respective sides of the triangle or pentagon. The inclined surfaces (10) are inclined closer to a central axis of the taper member (7) toward a base end of the anchor bolt (40). Each abutment part (12) has an inner surface (11) which is inclined closer to the central axis of the taper member (7) toward the base end and which abuts the inclined surface (10) of the taper member (7). In a state in which the taper member (7) and the abutment parts (12) are inserted into the attachment bore (2), when only the taper member (7) is moved toward an opening of the attachment bore (2), the outer peripheral surface (15) of the abutment parts (12) are pressed against the inner peripheral surface (2a) of the attachment bore (2) so that the abutment parts (12) are fixed in the attachment bore (2).

Abstract: An anchor bolt which is surely fixed to, for example, a rock wall and is easy to carry and store is provided. The anchor bolt according to the present invention has expandable devices (5) which are disposed at three locations of a rod (3). When the anchor bolt is inserted into a bore (2), a free end of an abutment part (16) of the expandable device (5) abuts an inner peripheral surface (26) of the bore (2), and expandable members (13) are held in the bore (2). In this state, when a taper member (12) is moved toward a base end of the anchor bolt along with the rod (3), an inclined surface (15) of the taper member (12) surface-contacts an inner surface (19) of the abutment part (16), and an outer peripheral surface (20) of the abutment part (16) is pressed against an inner peripheral surface 26 of the bore (2).

Abstract translation: 提供了可靠地固定到例如岩壁并且易于携带和存储的锚定螺栓。 根据本发明的锚栓具有设置在杆（3）的三个位置处的可扩张装置（5）。 当锚定螺栓插入孔（2）中时，可膨胀装置（5）的邻接部分（16）的自由端邻接孔（2）的内周表面（26）和可膨胀构件（13） ）保持在孔（2）中。 在这种状态下，当锥形构件（12）与杆（3）一起朝着锚定螺栓的基端移动时，锥形构件（12）的倾斜表面（15）表面接触内表面（19） ）和邻接部（16）的外周面（20）压靠在孔（2）的内周面26上。
