Abstract
The utility model discloses a tapered glass fiber reinforced plastic tray nut which comprises a tray and a nut, wherein a hole is formed in the tray, and the nut is matched with the hole. The tapered glass fiber reinforced plastic tray nut is easy to cut by adopting of glass fiber reinforced plastic, and has protecting function on a coal cutting tool bit. In addition, the tapered glass fiber reinforced plastic tray nut is anti-flammable, anti-static, safe in use, and especially suitable for being used in a high gas concentration area, and does not produce spark in cutting, and improves bearing capacity. The tapered glass fiber reinforced plastic tray nut is gradually locked when used, and is beneficial to safety construction of a roadway.
Description
Technical field
The utility model relates to the anchor rod-matched assembly, particularly a kind of tapered glass fibre reinforced plastics tray nut.
Background technique
Anchor pole is the superior structural of reinforcing for Rock And Soil, and suspension roof support is a kind of its support reinforcement mode that adopts in the underground chamber constructions such as the earth's surface engineering such as side slope, ground deep basal pit and tunnel, stope.Make roofbolt with metalwork, wooden part, polymer member, squeeze in the pre-drilled hole of earth's surface rock mass or chamber surrounding rock body, utilize special tectonic and the afterbody supporting plate of its head, the body of rod, or depend on cohesive action and country rock and rock mass stability are combined and produce suspension effectiveness, composite beam effect, reinforcing effect, to reach the purpose of supporting.Have that cost is low, supporting effect good, easy and simple to handle, use flexibly, take the advantages such as the construction headroom is few.
Suspension roof support forms an integral body and stable rock band by the mechanical state of the anchor pole change country rock of country rock inside itself on every side in the tunnel, utilizes anchor pole and country rock acting in conjunction, reaches the purpose of safeguarding stability of the roadway.It is a kind of supporting method of active defense, is the major transformation of mine support.Anchor pole not only supporting effect is good, and materials are economized, construction is simple, be conducive to mechanized operation, speed of application is fast.
The assembly tray nut of anchor pole is structure as a whole in the prior art, when bearing capacity is higher, and easy fracture, and because material is difficult for cutting, easily the coal mining cutter head is caused damage during cutting, quality is heavy, and is not easy to operate, increased difficulty of construction and workman's labor intensity.
The model utility content
The defective that exists in order to overcome above-mentioned prior art, the utility model provides a kind of tapered glass fibre reinforced plastics tray nut, is particularly suitable for high gas density zone, high-bearing capacity, more lock is tighter in use, has improved efficiency of construction.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of tapered glass fibre reinforced plastics tray nut comprises pallet and nut, and described pallet arranges the hole, and described nut and described hole coincide, and realizes connecting to embed pallet.
As preferably, the rib of some radial distribution is set on the pallet described in the utility model, strengthen the steadiness of pallet.
As preferably, hole described in the utility model is conical through-hole, is arranged on described pallet central authorities, to realize the embedding of nut.
As preferably, nut described in the utility model is tapered, comprises upper end part and end portion, and the tangent plane of described upper end part is regular hexagon, and the tangent plane of described end portion is circular.
As preferably, end portion vertical diameter described in the utility model is to some joint-cuttings are set.
As preferably, nut described in the utility model arranges endoporus, on the described endoporus hole wall wall screw thread is set.
As preferably, the parameter of screw thread described in the utility model is: pitch is 9.9～10.1mm, and leading thread is 17.9～18.1mm.
As preferably, the diameter of endoporus described in the utility model is: 20.6～20.8mm.
The beneficial effects of the utility model are; glass steel material is so that easily cutting; the coal mining cutter head has been played protective action; but flame-retardant and anti-static uses safety in addition, can not produce spark during cutting; being particularly suitable for high gas density zone uses; improved bearing capacity, more lock is tighter in use, and is very favourable to the tunnel safety construction.

Embodiment:
Be easy to understand understanding in order to make creation characteristic of the present utility model, technological means and to reach purpose, further set forth the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1～Fig. 5, a kind of tapered glass fibre reinforced plastics tray nut comprises pallet 1 and nut 2, and described pallet 1 arranges hole 11, and described nut 2 embeds described hole 11, coincide with described hole 11, and realization is connected with pallet 1.The rib 12 of some radial distribution is set on the described pallet 1, is preferably 6, increase the firm degree of pallet.Described hole 11 is conical through-hole, is arranged on described pallet 1 central authorities, and through-hole wall is smooth surface.Described nut 2 is tapered, comprise upper end part 21 and end portion 22, as preferably, 21 peripheries, described upper end part evenly arrange 6 conical surfaces, so that the tangent plane of upper end part 21 forms regular hexagon, orthohexagonal setting is so that fix nut 2 when connecting anchor pole, therefore also can be set to 4 conical surfaces forms square.The tangent plane of described end portion 22 is circular, and described end portion 22 vertical diameters are preferably 2 joint-cuttings to some joint-cuttings 23 are set.Described nut 2 arranges endoporus 25, on the described endoporus 25 hole wall walls screw thread 24 is set.As preferably, the parameter of described screw thread 24 is: pitch is 9.9～10.1mm, and leading thread is 17.9～18.1mm, and the diameter of described endoporus 25 is: 20.6～20.8mm.
When nut 2 is connected with pallet 1, because the tapered lower end part 22 of nut 2 matches with the inverted cone through hole of pallet 1, so that being connected with pallet, nut 2 can connect well, and the joint-cutting that arranges on the end portion 22, so that the connection that nut 2 is connected with pallet reaches maximization, increase simultaneously the elasticity of nut 2, avoided cracked under the significant stress when realizing the tighter effect of lock more.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
