Abstract
The inventive nut assembly comprises a nut, whose one end is a hexagon and the other end is a conicalness. On the conicalness there is an opening and outside the conicalness is sleeved a casing pipe. The inner hole of the casing pipe is an inner conicalness with the same taper as the nut conicalness.
Description
Technical field
The present invention relates to a kind of nut assembly, the nut assembly that especially a kind of member for reinforced glassfiber whole-thread rockbolt is used.
Background technique
At present, anchor pole is the very big supporting apparatus of mine consumption.All be to adopt timber in the past, but, also caused the waste of the forest resources because strength of wood is poor, perishable as the supporting apparatus.Also adopted anchor metal afterwards, but in the tunnel, use anchor metal, be easy to generate spark, cause unsafe factors such as gas explosion, so developed the glass fibre anchor pole afterwards, its tensile strength far surpasses anchor metal, and has the cutting of being easy to, can not produce spark, no ELECTROMAGNETIC REFLECTION, intensity height, advantage such as in light weight, corrosion-resistant are used increasingly extensive.But anchor pole need fix with nut, and nut can not be used metallic article.At present, the nut of fixing glass fiber threaded anchor rod is to make of a kind of high-strength engineering plastic, but its intensity is still not very good, can crack, and tensile strength is not high.For improve the intensity of nut have only with nut do thicker, bigger, just can meet the demands, so the fabricating cost height uses also not very convenient.And the anti-pulling-out force of existing anchor nut is also not enough, breaks a situation that the tooth nut comes off through regular meeting.
Summary of the invention
The nut assembly that provides a kind of member for reinforced glassfiber whole-thread rockbolt to use is provided.This assembly parts has improved the intensity of nut greatly, but has increased the bearing capacity of nut assembly.
Technological scheme of the present invention is: the nut assembly that member for reinforced glassfiber whole-thread rockbolt is used, and this assembly parts comprises nut 1, and an end of nut 1 is a hexahedron 2, and the other end is a cone 3, and opening 7 is arranged on the cone 3; The outside of cone 3 is with sleeve pipe 4, and the endoporus of sleeve pipe 4 is female cone bodies 5 identical with cone 3 taperings of nut 1, is with reinforcing sleeve 6 in sleeve pipe 2 outsides.
The nut assembly that aforesaid member for reinforced glassfiber whole-thread rockbolt is used, opening 7 is more than 1 or 1.
Aforesaid sleeve pipe 4 formations comprise that inner sleeve 8 and reinforcing sleeve 6, the endoporus of inner sleeve 8 are female cone bodies 5 identical with cone 3 taperings of nut 1, and reinforcing sleeve 6 is in the outside of inner sleeve 8.
Aforesaid reinforcing sleeve 6 is to make of nonmetallic material with inner sleeve 8.
In the nut assembly that aforesaid member for reinforced glassfiber whole-thread rockbolt is used, reinforcing sleeve 6 can be made of one with inner sleeve 8.
The nut assembly that aforesaid member for reinforced glassfiber whole-thread rockbolt is used, reinforcing sleeve 6 usefulness glass fibre reinforced plastic materials are made, and nut 1 and inner sleeve 8 usefulness high-strength engineering plastics are made.
In the nut assembly that aforesaid member for reinforced glassfiber whole-thread rockbolt is used, reinforcing sleeve 6 is to make with the glass fiber cloth that twines or silk and resin.
Compared with prior art, the nut assembly that member for reinforced glassfiber whole-thread rockbolt provided by the invention is used, the intensity height, in light weight, fabricating cost is low.Nut with diameter phi 22 compares, and nut cost originally is about 7 yuan, and present nut assembly cost is about 3.5 yuan; Nut bearing capacity originally is no more than 8 tons, and the bearing capacity of the nut assembly of now same diameter can reach more than 14 tons.The present invention is easy to implement, the technique effect highly significant.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan view of nut 1.
Embodiment
Embodiment: the structure of the nut assembly that member for reinforced glassfiber whole-thread rockbolt is used as shown in Figure 1, the nut assembly that member for reinforced glassfiber whole-thread rockbolt is used comprises nut 1, one end of nut 1 is a hexahedron 2, the other end is a cone 3, on the cone 3 society be provided with 2 symmetries opening 7 (opening 7 can for 1 or 1 with last, select for use in this example is 2), the distance of opening 7 is 2mm; The outside of cone 3 is with sleeve pipe 4, and sleeve pipe 4 formations comprise that inner sleeve 8 and reinforcing sleeve 6, the endoporus of inner sleeve 8 are female cone bodies 5 identical with cone 3 taperings of nut 1, and reinforcing sleeve 6 is in the outside of inner sleeve 8.Reinforcing sleeve 6 is with the glass fiber cloth of glass fibre reinforced plastic material or winding or silk and resin making, also can make of carbon fiber or other fibers.Nut 1 and inner sleeve 8 are to make of high-strength engineering plastic.Reinforcing sleeve 6 also can be made of one with commaterial with inner sleeve 8.
Make the nut 1 that anchor pole is used with high-strength engineering plastic earlier during making, one end of the nut 1 that anchor pole is used is a hexahedron 2, the other end is a cone 3, society is provided with the opening 7 of 2 symmetries on the cone 3, the screw thread identical with anchor pole arranged in the nut 1, cone 3 outsides on the nut 1 are with inner sleeve 8, the interior circle of inner sleeve 8 is made into female cone body 5, and it is identical with cone 3 taperings on the nut 1, glass fiber cloth or silk are wrapped on the cylindrical of inner sleeve 8, make tackiness agent with epoxy resin (or unsaturated polyester resin), promptly form reinforcing sleeve 6 after the drying.Owing to increase opening 7, in the nut fixing anchor bar, be subjected to the pressure of 8 pairs of cones 3 of inner sleeve, opening 7 is dwindled, thereby make cone 3 pack tightly anchor pole, its axial bearing capacity is greatly improved, with the nut comparison of diameter phi 22, nut cost originally is about 7 yuan, and present nut assembly cost is about 3.5 yuan; Nut bearing capacity originally is no more than 8 tons, and the bearing capacity of the nut assembly of now same diameter can reach more than 14 tons.
It is to process hole taper for convenience that inner sleeve 8 selects for use plastics to make, it also can with 6 be an integral body, sleeve pipe 4 also can be made of metal, but its effect does not have plastics or glass fibre ideal.
