Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with accompanying drawing description and specific embodiment:

[0028] see figure 1 , figure 2 , Figure 5 , Figure 9 , Figure 10 , a wedge-type self-locking inner anchor head of the present invention has a body 1 that matches the anchor hole 9, and the body 1 is provided with a wedge groove corresponding to the inner cone segment 8 in the anchor hole 9 10. There is a pin 3 in the wedge groove 10 hinged with one end of the wedge 2, and the other end of the wedge 2 faces the opening of the anchor hole 9 and radially expands through the outward tension mechanism 4.

[0029] One or more layers of wedge grooves 10 can be vertically arranged on the body 1, and the number of layers of wedge grooves 10 is determined by the functional requirements of the anchor. The longitudinal distribution positions of the inner cone segments 8 are matched. A metal cylindrical bar can be used as the body ...

Abstract

A jam-wedge type self-locking inner anchor head belongs to the technical field of rock or concrete anchoring, which is characterized in that: a body (1) is provided with a wedge groove (10) corresponding to an endocone segment (8) in an anchor eye (9); in the wedge groove (10), a pin roll (3) is hinged with one end of a wedge block (2) and the other end of the wedge block (2) faces the orifice of the anchor eye (9) radially extends through an extending mechanism (4). The jam-wedge type self-locking inner anchor head with wide application has the advantages of satisfying the design requirements that anchorage force is allotted to multilayer anchor heads as design requires; the anchor head can be applied to both frontal and inverted conical-surface hole slashes of the anchor eye endocone segment, the anchor head can be linked with various anchor material, such as an anchor rod or an anchor rope, the reliability and durability of anchoring are greatly enhanced, big technical difficult problems in inherent stress anchoring project are solved and the anchor head is particularly applicable to inherent stress anchoring of important projects.

Description

technical field [0001] The invention relates to an anchor piece or a pre-embedded part, which belongs to an anchor head for rear anchoring, in particular to a wedge-type self-locking inner anchor head. Background technique [0002] Chinese patent announcement number: 2404619Y, announcement date: November 8, 2000, utility model name: "A Concrete Self-locking Inserting Rod and a Matching Reaming Drill Bit", which proposes a self-locking inserting rod composed of an inserting rod and a wedge , The insertion rod is a steel bar with 2-8 cuts at the lower end, and the wedge is a steel wedge with a round upper point. When using, use the reaming drill to cut out a tapered wedge surface on the wall of the straight hole, then put the tip of the wedge upward into the bottom of the reamed hole, and put the cut end of the insert rod on the wedge , hit the plunger downward, so that the cut at the lower end of the plunger opens along the tapered surface of the wedge, and is inserted into ...
