摘要： A bolt-like fixing assembly for use in improving the strength and/or stability characteristics of rock structure, such as for reinforcing rocks, includes an elongate structure one end of which is adapted to be fixed within a bore formed in a rock and a device for fixing the other end of the elongate structure to the surface of the rock. According to aspects of the invention, the elongate structure is constituted of at least two rod-like members and a fixing device of the elongate structure is constituted by a wedge-shaped member and a bearing plate, such as a washer. The elongate structure is preferably constituted of three rod-like members, each of which preferably is constituted of a bulb steel rod.
