Increase, executive information systems emerge in large numbers, and foundation is deeper and deeper.Meanwhile as the basement part of the functions such as garage, skirt
The development and utilization of room or relatively independent underground structure is more and more extensive.Such underground structure construction area is big, basic
It buries relatively deeply, in historical high level of ground water, structure base slab self weight is insufficiently resistant to the buoyancy of underground water to send out
Raw to destroy or deform, the anti-floating problem of underground structure becomes increasingly conspicuous.In consideration of it, it is proposed that a kind of novel anchor rod stake.
Utility model content
The purpose of this utility model is to provide a kind of novel anchor rod stakes, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions:
A kind of novel anchor rod stake, including cushion cap, the cushion cap inside are equipped with bolthole, are equipped with anchor inside the bolthole
Bar main reinforcement is equipped with several middle bracket hoops in the anchor pole main reinforcement, is mounted on centering bracket, institute on each middle bracket hoop
It states and is also filled with high-pressure grouting body inside bolthole.
Preferably, the anchor pole main reinforcement is welded by three reinforced-bar bindings, and the diameter of each reinforcing bar is 25mm.
Preferably, the middle bracket hoop is linearly spaced substantially equidistant at least provided with three on each reinforcing bar, and each
The distance between two neighboring middle bracket hoop on reinforcing bar is 2m.
Preferably, it is closely welded and fixed between the middle bracket hoop and reinforcing bar, between the centering bracket and middle bracket hoop
Closely it is welded and fixed.
Preferably, the aperture of the bolthole is 200mm.
Compared with prior art, the utility model has the beneficial effects that
The utility model is suitable for foundation stabilization, prevents floor sinking, inclination etc., there is resistance to plucking, resistance to compression, shearing resistance etc. to make
With not needing banding steel cage, using cement mortar slip casting, than conventional anchor stake save the cost 50%, and speed of application is fast, again
It can make up for it other pile driving construction noises big, low efficiency, the deficiencies of environmental pollution is serious.

Convenient for description the utility model and simplify description, rather than the equipment of indication or suggestion meaning or element must have specifically
Orientation is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution:
A kind of novel anchor rod stake, including cushion cap 1 are equipped with bolthole 2 inside cushion cap 1, are equipped with anchor pole master inside bolthole 2
Muscle 3 is equipped with several middle bracket hoops 4 in anchor pole main reinforcement 3, it is each in be mounted on centering bracket 5 on bracket hoop 4, in bolthole 2
Portion is also filled with high-pressure grouting body 6.
In the present embodiment, anchor pole main reinforcement 3 is welded by three bindings of reinforcing bar 30, and the diameter of each reinforcing bar 30 is
25mm。
In the present embodiment, middle bracket hoop 4, at least provided with three, is linearly spaced substantially equidistant on each reinforcing bar 30, and
The distance between two neighboring middle bracket hoop 4 on each reinforcing bar 30 is 2m.
It in the present embodiment, is closely welded and fixed between middle bracket hoop 4 and reinforcing bar 30, between centering bracket 5 and middle bracket hoop 4
Closely it is welded and fixed.
In the present embodiment, the aperture of bolthole 2 is 200mm.
It is worth noting that bolthole 2 should carry out a normal pressure grouting, the slurry of high-pressure grouting body 6 using M30 neat slurry
Liquid is cement paste, and cement grade: the ratio of mud: 425# carries out secondary high pressure grouting, pressure after 0.45~0.5,24~48 hours
No less than 2.5MPa, the ratio of mud are that 0.55 or so (concrete condition is determined according to field test) determines.
Further, reinforcing steel bar corrosion inhibitor SY-R should be mixed in the cement slurry of high-pressure grouting body 6, guarantee anchor pole main reinforcement 3
Corrosion Protection extends the service life of anchor pole main reinforcement 3.
Utility model works principle: first passing through pilot hole machine on 1 surface of cushion cap and open up bolthole 2, then makes anchor pole master
Muscle 3, anchor pole main reinforcement 3 are welded together using the binding of reinforcing bar 30 of 3 diameter 25mm, and it is right together that 3 inside of anchor pole main reinforcement is added every 2.m
Middle bracket hoop 4, to prevent 3 torsional deformation of anchor pole main reinforcement, anchor pole main reinforcement 3 is when butt welding connects at the scene, it should be noted that place it is straight, three
30 firm welding group of reinforcing bar is integral.After 2 pore-forming of bolthole, bolthole 2 is cleaned up using high pressure water, is put into anchor pole main reinforcement
3, bar main reinforcement 3 is in place, and using tower crane handling, directly hanging is uprightly helped in the end of anchor pole main reinforcement 3 and surely slowly falls into bolthole 2
In place, 3 top of anchor pole main reinforcement is hung over 2 No. 5 channel steel systems are horizontal when necessary, is suspended on the bracket of aperture and unloads hook again, to anchor pole master
After muscle 3 is put into, high-pressure grouting body 6 is injected into bolthole 2, bolthole 2 should carry out a sub-atmospheric pressure filling using M30 neat slurry
Slurry, slurries are cement paste, cement grade: 425#, the ratio of mud: 0.45~0.5；Secondary high-pressure filling is carried out after 24~48 hours
Slurry, pressure are no less than 2.5MPa, and the ratio of mud is that 0.55 or so (concrete condition is determined according to field test) determines.High-pressure grouting
Reinforcing steel bar corrosion inhibitor SY-R is mixed in body 6, guarantees the Corrosion Protection of anchor pole main reinforcement 3, extends the service life of anchor pole main reinforcement 3.
After the completion of anchor bolt construction, 5% anchor pole that should randomly select sum carries out an acceptance inspection pullout tests, and test should be in mortar
Intensity carries out after reaching design strength, and test maximum axial pulling force is 540kN.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
