Description
Technical field
The utility model belongs to supporting apparatus technical field, is specifically related to glass fibre reinforced plastics rockbolts supporting and protection structure and glass fibre reinforced plastics rockbolts that a kind of mine working, highway, railway tunnel and slope retaining are used.
Background technology
Anchoring is used widely in the engineerings such as dam strengthening, underground structure supporting, slope stabilization, structure overturning or slip resistance analysis.As the critical component in anchoring---anchor pole, its effect is mainly firm rock mass, coal body and slight slope etc., prevents its avalanche.Common anchor pole is divided into wood bolt, bamboo anchoring-bolt, steel anchor rod.From service condition, wood bolt, bamboo anchoring-bolt control roadway surrounding rock effect is poor, intensity is low, corrosion-resistant; Steel anchor rod due to perishable, weight is large, simultaneously in the time excavating, easily produce spark and exist in actual use inconvenience.Product as an alternative, composite material anchor shaft because it is corrosion-resistant, intensity is high, the advantage such as lightweight, resistance to electromagnetism is subject to people's favor day by day.But, along with the continuous popularization of glass fibre reinforced plastics rockbolts application, also gradually expose the low and low shortcoming of twisting resistance of himself elongation per unit length.For example: when tunnel is subject to dynamic pressure impact or is out of shape when excessive, the stress acting on glass fibre reinforced plastics rockbolts becomes large, due to the low shortcoming of himself elongation per unit length, can cause the body of rod to break destruction.In addition, due to the low shortcoming of himself twisting resistance, in the time applying prestressing force, can be restricted, often not reach best anchoring effect.In addition, generally adopt recoverable anchor rod in order to save material, known recoverable anchor rod is generally made up of the anchor metal body of rod, pallet and nut.Because anchoring section and the body of rod of the anchor metal body of rod are an entirety, anchoring section is anchored at and in rock mass, is difficult to the recovering effect that reaches desirable, causes on the contrary support cost to increase and slow down speed of application.
Utility model content
The purpose of this utility model is to provide a kind of glass fibre reinforced plastics rockbolts supporting and protection structure and glass fibre reinforced plastics rockbolts, to solve the bad problem of existing anchor recovering effect.
Glass fibre reinforced plastics rockbolts of the present utility model comprises the body of rod, pallet and nut, and the described body of rod comprises body of rod main body and body of rod anchoring section, and the connecting portion of this body of rod anchoring section and body of rod main body is provided with respectively the internal and external screw thread matching, and is connected by internal and external screw thread.
Further, described body of rod anchoring section is the glass fiber reinforced plastic that surface is shape of threads, one end and arranges internal thread, and one end of body of rod main body is provided with external screw thread.
Further, between described pallet and nut, be provided with metal by casting die.
Further, described metal is metal by pressure ring or metal by pressure pipe by casting die.
Glass fibre reinforced plastics rockbolts supporting and protection structure of the present utility model comprises Chain Link Fence and at least two glass fibre reinforced plastics rockbolts, this glass fibre reinforced plastics rockbolts comprises the body of rod, pallet and nut, described at least two glass fibre reinforced plastics rockbolts are pressed on the wire of Chain Link Fence by pallet respectively, the body of rod of described glass fibre reinforced plastics rockbolts comprises body of rod main body and body of rod anchoring section, the connecting portion of this body of rod anchoring section and body of rod main body is provided with respectively the internal and external screw thread matching, and is connected by internal and external screw thread.
Further, surface, described body of rod anchoring section position is shape of threads, one end and arranges the glass fiber reinforced plastic of internal thread, and one end of body of rod main body is provided with external screw thread.
Further, between described pallet and nut, be provided with metal by casting die.
Further, described metal is metal by pressure ring or metal by pressure pipe by casting die.
The glass fibre reinforced plastics rockbolts that glass fibre reinforced plastics rockbolts supporting and protection structure of the present utility model and this structure are used combines anchor pole main body and glass fiber reinforced plastic anchoring section by internal and external screw thread, this demountable structure can make anchor metal main body repeatedly reclaim and reuse, reduce support cost, accelerate speed of application.Between pallet and nut, metal is set by casting die, can be by metal the controllable deforming by casting die, give full play to the supporting capacity of roadway surrounding rock self, overcome in the past the low and poor shortcoming of anchoring effect of common bolt support system stretching resistance.
