Background technology
When carrying out the underground engineering constructions such as mine and tunnel, the excavation of underground passage can make the deformation energy that country rock generates to
Free space discharge, with the continuous increase of mining depth, supporting is given to roadway surrounding rock with ensure underground engineering it is smooth into
Row is extremely important.In underground engineering in common support apparatus, suspension roof support reaches 80% or more, is most common and most important
Support pattern, therefore the construction quality of anchor pole is related to the supporting effect of entire engineering, but in certain particular locations, such as in Da Xiang
When road FLOOR ANCHOR, the construction angle of anchor pole can only be estimation installation, it is difficult to ensure that the construction angle of FLOOR ANCHOR, to cause
FLOOR ANCHOR setting angle is inaccurate；Furthermore mounted anchor pole, outer end are generally sleeved on using nut tightening on anchor pole
Pallet makes pallet be contacted with coal and rock and carrys out fixing anchor bar, and such pressure acts directly on pallet on coal petrography contact level, this is very
It is easy to keep contact surface destruction imperfect, both the above situation finally all can cause Effects of Supporting that desirable, shadow is not achieved
Ring tunnel safety stability.
Invention content
The present invention provides a kind of FLOOR ANCHOR band angle mounting device and installation method, is constructed with solving existing FLOOR ANCHOR
Setting angle is not accurate in the process and anchor rod pallet board is caused coal petrography contact level to be easy to coal petrography contact level by compared with power concentration
The technical issues of destruction.
To achieve the above object, a kind of FLOOR ANCHOR band angle mounting device provided by the invention, including it is bevel edge steel plate, perpendicular
Straight steel plate and bottom surface steel plate, the end of the bevel edge steel plate, vertical steel plate and bottom surface steel plate are interconnected to right angled triangle, institute
It states bevel edge steel plate center and offers the bevel edge through-hole and vertical plane through-hole for matching bolt diameter respectively with vertical steel plate corresponding position, when
FLOOR ANCHOR can reach FLOOR ANCHOR setting angle requirement when passing through the bevel edge through-hole and vertical plane through-hole.
The bevel edge steel plate, vertical steel plate and bottom surface steel plate carry out length dimension according to FLOOR ANCHOR construction angle requirement
Adjustment, three's length dimension meets Pythagorean theorem, and is welded into right angled triangle.
The bevel edge through-hole and the vertical plane through-hole line of centres perpendicular to bevel edge steel plate surface, and with the bottom surface steel plate where face
It is in a certain angle, it can reach FLOOR ANCHOR setting angle requirement when FLOOR ANCHOR passes through the bevel edge through-hole and vertical plane through-hole.
The present invention also provides any of the above-described kind of installation method of the FLOOR ANCHOR with angle mounting device is utilized, specifically include：
A, the present apparatus is placed on construction tunnel base angle position and is adjacent to work surface；
B, the bevel edge through-hole of the present apparatus and vertical plane through-hole is passed through to reach work surface on the drilling rod of jumbolter；
C, it starts jumbolter and carries out inclined drill construction；
D, Anchor Agent and anchor pole are inserted into the inclined drill constructed；
E, pallet is sleeved on anchor pole after stirring and is adjacent to bevel edge steel plate surface, rotating nuts hold out against pallet, and FLOOR ANCHOR is made to fasten.
Compared with prior art, beneficial effects of the present invention are：
First, the present apparatus only has three blocks of steel plates and is welded, economical simple and durable；Secondly, the present apparatus can be by adjusting three in advance
Relationship between block steel plate length is come FLOOR ANCHOR setting angle accurate problem when realizing tunnel design and construction；Finally, this dress
It sets and uses most stable of three-legged structure, can effectively ensure that the stability of the present apparatus, while by anchor rod pallet board and coal and rock
Contact becomes anchor rod pallet board and is contacted with steel plate, can effectively avoid the destruction between coal petrography contact level, and by the pressure on contact surface
Power resolves into vertical and horizontal side and upwards pressure, this will greatly reduce the device and the pressure on the coal petrography contact level of tunnel,
It is capable of the complete of effective protection contact surface.In short, the configuration of the present invention is simple, practical and convenient, can not only effectively solve well
The accurate problem of FLOOR ANCHOR setting angle can also solve anchor rod pallet board with coal petrography contact level stress compared with concentration problem.
