Abstract

The invention discloses a two-piece anchorage device. The two-piece anchorage device is characterized by comprising a supporting plate (1), an anchor ring (2) and an anchor plug (3) and is also characterized in that the supporting plate (1) is integrally welded together with the anchor ring (2); the supporting plate (1) is square and provided with a circular hole at the center; the anchor plug (3) is in the form of two pieces; the vertical section of the anchor plug (3) is in the form of a right trapezoid; and the bottom angle of the right trapezoid is 75-77 DEG. The two-piece anchorage device disclosed by the invention has the advantages of convenient manufacturing, reasonable application method, simple structure, energy-saving and environment friendly properties, economic efficiency, durability, practicability and high efficiency according to a simple principle; therefore, the two-piece anchorage device is convenient and practical.

Description

technical field [0001] The invention relates to the field of anchors, in particular to a two-piece anchor. Background technique [0002] The prior art results in poor stress state of most hydraulic expansion bolts after construction, which cannot guarantee a good supporting effect. Therefore, how to apply pre-tightening force to the hydraulic expansion bolt in time during roadway support construction is a problem that needs to be solved urgently in the underground field. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a two-piece anchorage with simple structure, convenient operation, economical and durable. [0004] A two-piece anchor, characterized in that it includes a supporting plate (1), an anchor ring (2), and an anchor plug (3), and is characterized in that: the supporting plate (1) and the anchor ring ( 2) welded together; the supporting plate 1 is square in shape and has ...
