Abstract
The utility model relates to a reducing anchor rod with increased bearing capacity, which comprises a screw section and a thread section, wherein the screw section and the thread section are of an integrated structure, the free end of the thread section is in threaded connection with a screw cap, and the diameter of the cross section of the thread section is larger than that of the cross section of the screw section. As the diameter of the cross section of the thread section is larger than that of the cross section of the screw section, the tail part of the anchor rod is increased, and the thread area is increased, thus enhancing the bearing capacity of the anchor rod.
Description
Technical field
The utility model relates to a kind of anchor pole, relates in particular to a kind of reducing anchor pole.
Background technology
At present, indulge in the muscle anchor pole process with left-handed nothing at operating mine, spiro rod section and thread segment adopt whole steel pole to make, originally, spiro rod section equates that with the cross-sectional diameter of thread segment after thread segment was opened silk, the cross-sectional diameter of thread segment can be slightly less than the cross-sectional diameter of spiro rod section, threaded area is less, and this makes the supporting capacity of anchor pole be subjected to very big restriction.
Summary of the invention
The purpose of this utility model provides the reducing anchor pole that a kind of supporting capacity increases.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of reducing anchor pole comprises spiro rod section and thread segment, and spiro rod section and thread segment are structure as a whole, the thread segment free end nut that has been threaded, and it is characterized in that: the cross-sectional diameter of thread segment is greater than the cross-sectional diameter of spiro rod section.
Because the cross-sectional diameter of the utility model thread segment makes that greater than the cross-sectional diameter of spiro rod section anchor pole afterbody pier is thick, has increased threaded area, thereby has strengthened the supporting capacity of anchor pole.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing:
1, spiro rod section 2, thread segment 3, nut
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
A kind of reducing anchor pole as shown in Figure 1, comprises spiro rod section 1 and thread segment 2, and spiro rod section 1 is structure as a whole with thread segment 2, the thread segment 2 free ends nut 3 that has been threaded, and the cross-sectional diameter of thread segment 2 is greater than the cross-sectional diameter of spiro rod section 1.
Make the crystal structure of body of rod afterbody, steel inside be improved after thread segment of the present utility model is upsetting, the supporting capacity of thread segment is fully greater than the supporting capacity of spiro rod section.
