Abstract
This utility model patent relates to a kind of pressure-relieving achor bar pallet.This structure mainly includes anchor pole, the hex nut of bar tail, half ball pivot, pallet and rubber grain concrete.Half ball pivot can regulate the axis direction of stress, can correct the Impact direction of anchor pole, solves owing to the improper anchor pole of setting angle is by the problem of failure by shear.Pallet uses bowl structure, and its internal rubber grain concrete springback amount is big, can effectively slow down country rock disturbance deformation and absorb the potential energy of deformation of country rock.This structure stress is reasonable, it is simple to construction, can be effectively improved the supporting intensity of anchor pole.This structure is widely used in underground engineering support, especially country rock disturbance is relatively big, crustal stress is bigger tunnel, the supporting in tunnel.
Description
Technical field
This utility model relates to a kind of pressure-relieving achor bar pallet, and this structure can be widely used in underground engineering support, especially
It is applicable to the supporting of great burying and high stress tunnel.
Background technology
In underground engineering suspension roof support, anchor rod pallet board, as in Bolt System significant points, is anchor pole
Main force-transmitting part, its performance directly influences the supporting effect of anchor pole.The effect of pallet is that nut check moment is produced
Raw thrust passes to top side, produces just anchor-hold, the most again by the pressure transmission of top, tunnel side to anchor pole, produces working resistance,
Jointly reinforce country rock, stop the displacement of top, tunnel side.So when selecting pallet, first having to meet anchor rod pallet board and anchor rod body
Coupling in supporting construction, it is to avoid because of anchor rod body and pallet not mating and cause anchor rod body and spiral shell in supporting construction
Female unbalance stress, affects the supporting effect in tunnel.It is secondary meets anchor rod pallet board and anchor rod body mating in intensity, it is to avoid
Anchor perforation phenomenon is caused because of the insufficient strength of anchor rod pallet board.
It is known that the simple tension optimal state that is rockbolt stress.The body of rod will be produced by the power in off-axis direction
Raw shear action, causes anchor pole to produce flexural deformation and even ruptures, greatly weaken the bearing capacity of anchor pole.Execute in underground engineering
In man-hour, owing to construction operation environment is relatively poor it is difficult to ensure that the stress of the anchor pole installed is unidirectional stretching, the most easily cut
The bearing capacity of weak anchor pole.Traditional anchor rod pallet board can not overcome problems.In view of this, need badly by new technique, new hand
The structure of Duan Youhua anchor pole.
Summary of the invention
The novel purpose of this use is to provide a kind of pressure-relieving achor bar pallet, can be widely used in underground engineering
Protect.
A kind of pressure-relieving achor bar pallet is by anchor pole, hex nut, half ball pivot, pallet and rubber grain concrete composition, its
Being characterised by, half ball pivot is between pallet and hex nut, and can play the regulation of preferable axle center after assembling with anchor pole and make
With；Rubber grain Concrete Filled inside pallet, its springback capacity play greatly allow pressure effect, can effectively increase holding of anchor pole
Loading capability.
Preferably, pallet is used as bowl structure, its internal filled rubber granule concrete.
Preferably, rubber grain concrete is the C40 concrete of admixture rubber grain.
The beneficial effects of the utility model are: the hemisphere of this structure upper and anchor pole can play preferable axle after assembling
Heart regulation effect, makes anchor pole play the bearing capacity to country rock to greatest extent；Can inside the pallet of the bowl structure of bottom
Filled rubber granule concrete, the potential energy of deformation that surrouding rock deformation discharges is turned by the characteristic utilizing rubber grain concrete springback amount big
Turn to the deformation energy of self；The design of this structure is simple, it is simple to installs, is effectively improved speed of application.
Accompanying drawing explanation

Fig. 2 one pressure-relieving achor bar pallet top view；
Reference: (1) anchor pole；(2) hex nut；(3) half ball pivots；(4) pallet；(5) rubber grain concrete.
Detailed description of the invention
With embodiment, detailed description of the invention of the present utility model is described in further detail below in conjunction with the accompanying drawings.Following reality
Example is used for this utility model is described, but is not limited to scope of the present utility model.
As it is shown in figure 1, a kind of pressure-relieving achor bar pallet that this utility model embodiment provides includes anchor pole, hex nut, half
Ball pivot, pallet and rubber grain concrete.
During use, first by rockbolt installation to boring, rubber grain concrete is added water and stirs by scene subsequently,
Bowl-shape pallet put into by the rubber grain concrete taking appropriate mix again, then makes real and reserving installation hole with hands, treats rubber
After granule concrete initial set, whole pallet is installed on anchor pole, finally hemisphere at bar tail and is used hexagonal through rockbolt installation
Nut screwing clamping.This structure can significantly improve the utilization rate of anchor pole, and the rubber grain concrete within pallet first can be utilized to return
The characteristic that bullet amount is big discharges crustal stress timely, can effectively prevent anchor pole from reaching self-strength fracture, and next utilizes hemisphere
The effect of body its axle center, makes anchor pole be at, when arranging, the optimal stress that simple tension is not sheared, maximum
The performance anchorage effect of limit, improves the bearing capacity of anchor pole.This structure can be widely used in underground engineering support, especially
It is applicable to the supporting of great burying and high stress tunnel.
As improvement, pallet is used as bowl structure, its internal filled rubber granule concrete.
As improvement, rubber grain concrete is the C40 concrete of admixture rubber grain.
