Abstract
The utility model discloses a nut assembly used in a fiberglass full-thread roof bolt. The assembly comprises a nut (1) and a tray (2), wherein, one end of the nut (1) is provided with a polygonal column body (3), while the other end of the nut (1) is provided with a tapered cylinder body (4); and the tray (2) is sleeved on the tapered cylinder body (4). In the nut assembly used in the fiberglass full-thread roof bolt, because the tapered fit is adopted by the nut and the tray, and a groove is arranged on the nut, the nut can be combined with the fiberglass full-thread roof bolt more tightly under the action of the tray, and bearing capacity of the nut assembly can be greatly improved. The structure has the characteristics of high strength, light weight and low manufacturing cost. The nut assembly can be used on the fiberglass full-thread roof bolt, a part-thread roof bolt and other fiberglass reinforced plastic rod bodies.
Description
Technical field
The utility model relates to the nut assembly that a kind of threaded anchor rod is used, the nut assembly of particularly a kind of fiber glass full-thread bolt (claiming Full Thread FT fiberglass-reinforced plastic lever body again) usefulness.
Background technique
Anchor pole is the very big supporting apparatus of mine consumption.The at present general glass fibre anchor pole that uses, its tensile strength far surpasses anchor metal, and has the cutting of being easy to, can not produce spark, and 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 bearing capacity of existing anchor nut is also not enough, breaks a situation that the tooth nut comes off through regular meeting.If it is too tight that present in addition nut and glass fibre anchor pole cooperate, in spin nut, require great effort very much, pine also can influence bearing capacity if nut and glass fibre anchor pole cooperate too.Have a kind of nut assembly to solve the problems referred to above, this nut assembly can be spun on the glass fibre anchor pole easily, can guarantee closely cooperating of nut and anchor pole again in use, strengthens bearing capacity.But this nut assembly size is bigger, and height can increase the area of section in tunnel after the use about 120mm, increase cost of winning; And member is many, and fabricating cost is higher.
The model utility content
The purpose of this utility model is, the nut assembly that provides a kind of novel fiber glass full-thread bolt to use.This nut assembly member is few, size is little, can reduce production costs, and also can reduce the area of section in tunnel, reduces cost of winning widely.And still can be spun on easily on the glass fibre anchor pole, guarantee closely cooperating of nut and anchor pole, strengthen bearing capacity.
The technical solution of the utility model: the nut assembly that fiber glass full-thread bolt is used is characterized in that: this assembly parts comprises nut and pallet; One end of nut is the polygonal cylinder, and the other end of nut is a tapered cylinder; Tray sleeve is on the tapered cylinder of nut.
In the nut assembly that above-mentioned fiber glass full-thread bolt is used, the internal thread profile of tooth of described nut and the outside thread profile of tooth of fiber glass full-thread bolt match.
In the nut assembly that aforesaid fiber glass full-thread bolt is used, be radial two or more grooves that have on the tapered cylinder of described nut.
In the nut assembly that aforesaid fiber glass full-thread bolt is used, described pallet is provided with the conical surface endoporus, and the tapered cylinder of its tapering and nut matches.
In the nut assembly that aforesaid fiber glass full-thread bolt is used, described pallet is provided with the reinforcement boss, is strengthening being provided with two or more reinforcement gussets on the boss.
In the nut assembly that aforesaid fiber glass full-thread bolt is used, stud with one or more stiffening ring in the conical surface endoporus of described pallet.
In the nut assembly that aforesaid fiber glass full-thread bolt is used, described nut and pallet are made of high-strength engineering plastic.
In the nut assembly that aforesaid fiber glass full-thread bolt is used, described nut and pallet are made of glass fibre reinforced plastic material.
Compared with prior art, the nut assembly that the fiber glass full-thread bolt that the utility model provides is used, because nut and pallet adopt taper fit, and on nut, have a groove, under the effect of pallet, make nut can with fiber glass full-thread bolt combination more closely, strengthened the bearing capacity of nut assembly greatly.And this nut assembly member is few, size is little, highly has only 60mm, can reduce production costs, and also can reduce the area of section in tunnel, has reduced cost of winning widely.The utlity model has intensity height, member is few, in light weight, size is little, fabricating cost is low, implementation result is good characteristics.The utility model can be used on fiber glass full-thread bolt, part threaded anchor rod and other fiberglass-reinforced plastic lever body.

Embodiment
Embodiment.The nut assembly that fiber glass full-thread bolt is used.This assembly parts comprises nut 1 and pallet 2; One end of nut 1 is a polygonal cylinder 3, so that be fixed for screwing nut, the other end of nut 1 is a tapered cylinder 4; Pallet 2 is enclosed within on the tapered cylinder 4 of nut 1.Internal thread 5 profiles of tooth of nut 1 and the outside thread profile of tooth of fiber glass full-thread bolt match.Symmetry has two grooves 6 on the tapered cylinder 4 of nut 1.Also can as required open 3 ~ 5 such grooves more and tighten up degree with increase.When pallet 2 was enclosed within on the tapered cylinder 4 of nut 1, groove 6 can tighten up, and nut 1 and fiber glass full-thread bolt are closely cooperated, to improve the bearing capacity of nut assembly.Pallet 2 is provided with conical surface endoporus 7, and the tapered cylinder 4 of its tapering and nut 1 matches.On pallet 2, be provided with and strengthen boss 8, strengthening being provided with two or more reinforcement gussets 9 on the boss 8, and in the endoporus 7 of pallet 2, inlaying one or more stiffening ring 10.Stiffening ring 10 can be made with high-intensity metal.Above-mentioned nut 1 and pallet 2 can be made of high-strength engineering plastic.Nut 1 and pallet 2 usefulness glass fibre reinforced plastic materials are made in the present embodiment.
