Abstract
The utility model relates to a metal anchor rod with a thick tail, which is composed of a main body (1) of the anchor rod, and an anchor tail (2). The metal anchor rod with a thick tail is characterized in that the main body (1) of the anchor rod and the anchor tail (2) form a whole. Screw threads (3) are arranged on the anchor tail (2). In addition, a diameter of the anchor tail (2) is larger than the diameter of the main body (1) of the anchor rod. The metal anchor rod with a thick tail has the advantages of simple structure, difficult abruption of the tail part of the anchor rod, high stretch-proof strength, great anchoring force and extending force, good supporting and protecting effect, and low cost.
Description
The utility model relates to a kind of thick tail metal bolt, relates to a kind of anchored force that is used for specifically and requires greatly, rock deformation big and all kinds of full anchor of anchor tail easy fracture or the thick tail High strength bolt of metal of end road, anchor lane (tunnel) support engineering.
At present, all relate to the anchor metal that geotechnical engineering is reinforced and supporting is used in coal, metallurgy, railway, building and side slope etc., because its structure is that body of rod diameter is identical with anchor pole tailing screw flight diameter, so the net sectional area of anchor pole tailing screw flight part reduces about 22% than body of rod sectional area, therefore, under the anchor pole action of pulling stress in use, at first in thread root generation plastic strain until disrumpent feelings, so its structure of existing anchor pole awaits improving.
The purpose of this utility model is to design a kind of anchor pole main body and the anchor tail is the high-intensity thick tail metal bolt of one.
The purpose of this utility model is to realize like this, it is made up of anchor pole main body (1) and anchor tail (2), it is characterized in that: anchor pole main body (1) and anchor tail (2) are an integral body, and anchor tail (2) is provided with screw thread (3), and the diameter of anchor tail (2) is greater than the diameter of anchor pole main body (1).
The utility model compared with prior art, it is simple in structure, the anchor pole afterbody is easy fracture not, the tensile strength height, anchored force and stretching force are big, supporting effect is good, and is with low cost.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model integral body (omitting a segment length) schematic appearance.
Accompanying drawing 2 is the utility model integral body (omitting a segment length) sectional structure schematic diagram.
Wherein: 1, anchor pole main body, 2, the anchor tail, 3, screw thread.
Referring to accompanying drawing: as can be seen from the figure it is made up of anchor pole main body 1 and anchor tail 2, and anchor pole main body 1 and anchor tail 2 are an integral body, that is: anchor pole main body 1 and anchor tail 2 are the integral body of identical material, and no-welding type connects.The implementation procedure of this product embodiments is as follows: in steel rolling mill's operation of rolling, the life cycle milling train, length by anchor pole main body 1 and anchor tail 2 in the design designs two kinds of passes on same circumference, one section pressure rolling anchor pole main body 1 wherein, another section pressure rolling anchor tail 2, owing to reserve roller by design length, so in the length of design: anchor pole main body 1 can produce does not have vertical muscle left hand thread steel, anchor pole main body 1 also can produce not reinforcement smooth bar, and anchor tail 2 produces light face screw-thread steel.Rolled thread machining screw on light face screw-thread steel again, promptly anchor tail 2 is provided with screw thread 3, and the diameter of anchor tail 2 is greater than the diameter of anchor pole main body 1.
Claims (1)
1, a kind of thick tail metal bolt, it is made up of anchor pole main body (1) and anchor tail (2), it is characterized in that: anchor pole main body (1) and anchor tail (2) are an integral body, and anchor tail (2) is provided with screw thread (3), and the diameter of anchor tail (2) is greater than the diameter of anchor pole main body (1).
