Abstract
A kind of steel disc has bushing type soil anchor bolt anchor head, including the tubbiness anchor pole wall separately surrounded by multiple pieces of steel (1), the anchor pole pars intramuralis is provided with steel strand wires (2) or reinforcing bar, anchor pole wall bottom is provided with bottom plate (3), top plate (4) are provided at the top of anchor pole wall, the steel strand wires (2) or reinforcing bar bottom are connect with bottom plate (3), steel strand wires (2) or reinforcing bar pass through the interstitial hole of top plate (4) and are not connected and fixed with top plate (4), top plate (4) top is provided with sleeve (5), and anchor pole wall bottom fold is bullet.Single soil anchor bolt ultimate pullout capacity is greater than existing anti-floating pile；And it is easy for construction, it is relatively inexpensive.
Description
Technical field
The present invention relates to a kind of soil anchor bolt anchor head, more specifically to a kind of steel disc has bushing type soil anchor bolt anchor head, belongs to
In anchorage technology field.
Background technique
Soil anchor bolt is the soil layer internal drilling that do not excavate in deep foundation Tu Bi, after reaching certain depth, be put into hole reinforcing bar,
The materials such as steel pipe, steel tendon, steel strand wires pour into mud or chemical grout, and so that it is combined into tension with soil layer, (to pull out) power strong
Anchor pole.Soil anchor bolt end is coupled with lagging pile, prevents Tu Bi from collapsing or coming down；And due to not setting support in cheating, so construction item
Part is preferable.
Currently, having no the soil anchor bolt for anti-floating, Traditional project realizes this function using anti-floating pile.But anti-floating pile
It is larger compared to soil anchor bolt boring aperture, and its bottom not reaming, single anti-floating pile ultimate pullout capacity are less than soil anchor bolt；While at
This is also above soil anchor bolt, it is difficult to satisfy the use demand.
Summary of the invention
It is an object of the invention to for existing anti-floating pile ultimate pullout capacity be less than soil anchor bolt, it is at high cost the problems such as, mention
There is bushing type soil anchor bolt anchor head for a kind of steel disc.
To achieve the above object, institute using technical solution is the present invention: a kind of steel disc has bushing type soil anchor bolt anchor head,
Including the tubbiness anchor pole wall separately surrounded by multiple pieces of steel, the anchor pole pars intramuralis is provided with steel strand wires or reinforcing bar, anchor pole
Wall bottom is provided with bottom plate, is provided with top plate at the top of anchor pole wall, the steel strand wires or reinforcing bar bottom are connect with bottom plate, steel strand wires
Or reinforcing bar passes through the interstitial hole of top plate and is not connected and fixed with top plate, top plate top is provided with sleeve, and anchor pole wall bottom fold is
Bullet.
The anchor pole wall top straight section and lower cone body ratio is 1:1.
It is provided with cable wire at the anchor pole wall bottom fold, adjacent steel disc is connected by the cable wire.
The steel disc quantity is 10~12.
Compared with prior art, the beneficial effects of the present invention are:
Small using native country armature boring aperture, single soil anchor bolt ultimate pullout capacity is greater than existing anti-floating pile；And it is easy for construction, compared with
For economy.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 2.
Fig. 4 is usage state diagram of the present invention.
In figure, steel disc 1, steel strand wires 2, bottom plate 3, top plate 4, sleeve 5, cable wire 6.
Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 3, a kind of steel disc has bushing type soil anchor bolt anchor head, including the bucket separately surrounded by multiple pieces of steel 1
Shape anchor pole wall, the multi-disc at this are three pieces and three pieces or more；The anchor pole pars intramuralis is provided with steel strand wires 2 or reinforcing bar.Anchor pole
Wall bottom is provided with bottom plate 3, and top plate 4 is provided at the top of anchor pole wall 1；The steel strand wires 2 or reinforcing bar bottom are connect with bottom plate 3,
Steel strand wires 2 or reinforcing bar pass through the interstitial hole of top plate 4 and are not connected and fixed with top plate 4.4 top of top plate is provided with sleeve 5, steel strand wires
2 or reinforcing bar pass through sleeve 5 and steel strand wires 2 or reinforcing bar top and be located at outside sleeve 5；The anchor pole wall top is straight section, anchor pole wall
Bottom fold is bullet.
Referring to Fig. 1 to Fig. 3, the anchor pole wall top straight section and lower cone body ratio are 1:1.
Referring to Fig. 1 to Fig. 3, it is provided with cable wire 6 at the anchor pole wall bottom fold, the cable wire 6 is by adjacent steel
Piece 1 is connected.
Referring to Fig. 1 to Fig. 3, determination can be actually needed in 1 quantity of steel disc, and can choose 1 quantity of steel disc is 10~12.
This soil anchor bolt is put into anchor hole after anchor hole bottom hole completes drilling, reaming referring to Fig. 1 to Fig. 4, it is fixed
5 top of sleeve；Using drawing instrument drawing steel stranded wire 2 or reinforcing bar, top plate 4 and bottom plate 3 is set to generate relative displacement, steel disc 1 becomes
Shape, 1 bending part of steel disc outwardly protrudes at this time.Native country rockbolt installation is completed, sleeve 5 is taken out, grouting material is perfused into hole, is conserved
Completion.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, and above structure all shall be regarded as belonging to
Protection scope of the present invention.
