Embodiment

[0021] see attached Figure 1-6 ,

[0022] An expanded quick-install rock anchor in the present invention comprises a bolt 1, an upper wedge 3 and a lower wedge 4, the centers of the upper wedge and the lower wedge are respectively provided with a central long hole 2 longitudinally, and the upper The wedge block and the lower wedge block are provided with an inclined plane 6 along their longitudinal direction, and the included angle between the inclined plane and the axis in this embodiment is 30°. The slopes of the upper wedge and the lower wedge are set opposite to each other to form a corresponding sliding plane, and the central long hole of the upper wedge and the lower wedge runs through the anchor rod, and the anchor rod is a stepped shaft with a stepped circular platform structure, the bottom of its stepped circular platform 1-2 is provided with threads, and the upper wedge block and the lower wedge block are successively set on the anchor rod and screwed with the lowe...

Abstract

The invention relates to an extending fast-loading rock anchorage device. The extending fast-loading rock anchorage device is characterized by comprising an anchor rod, a lower nut, an upper wedge-shaped block and a lower wedge-shaped block, central long holes are formed in the center of the upper wedge-shaped block and the center of the lower wedge-shaped block respectively in the longitudinal direction, the upper wedge-shaped block and the lower wedge-shaped block are respectively provided with an inclined face in the longitudinal direction, the inclined face of the upper wedge-shaped block and the inclined face of the lower wedge-shaped block are oppositely arranged and are corresponding sliding planes, the anchor rod penetrates through the central long hole of the upper wedge-shaped block and the central long hole of the lower wedge-shaped block, the anchor rod is of a step shaft structure with a step circular truncated cone, threads are arranged on the lower portion of the step circular truncated cone of the anchor rod, and the anchor rod is sleeved with the upper wedge-shaped block, the lower wedge-shaped block and the lower nut in sequence. The extending fast-loading rock anchorage device has the advantages that due to the fact that a penetrating hole is communicated with the hollow portion of the upper wedge-shaped block and the hollow portion of the lower wedge-shaped block, when the device is pressed by an anchor bolt screw rod end circular truncated cone, the top end of an extending petal is radially expanded, the wedging function on surrounding materials is generated, and when an anchor bolt is completely tightened, the larger the tensile force borne by the anchor rod is, the more tightly anchoring is.

Description

technical field [0001] The invention belongs to anchors, in particular to an expanded quick-install rock anchor which can be quickly installed on solid substrates such as rocks and concrete. Background technique [0002] At present, most of the anchor bolts on rock or concrete substrates are placed by embedded parts, chemical gel, molten lead and other methods. Such construction methods often require the use of large equipment for construction, which not only has a long period of construction, but also is greatly affected by weather. The amount of construction is large and the cost is high; after construction, it takes a long time to play a role. Especially in places where it is not convenient for large equipment to enter, it is more difficult. By searching the prior art, patent application number: 93103787.5 discloses a concrete anchor bolt with an anchor bolt body, which is a rod-shaped member with a male thread and a knocking head at one end, and a cylindrical portion at...
