Abstract
A kind of steel pipe valve cutting formula soil anchor bolt anchor head, including the anchor pole wall formed by steel pipe (1), the anchor pole pars intramuralis is provided with steel strand wires (2) or reinforcing bar, anchor pole wall bottom is provided with pedestal (3), the steel strand wires (2) or reinforcing bar are connect with pedestal (3), and anchor pole wall lower part vertically offers the structure that multiple side through-holes form steel disc (4) and side through-hole is spaced apart.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 pipe valve cutting formula soil anchor bolt anchor head belongs to
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
For a kind of steel pipe valve cutting formula soil anchor bolt anchor head.
To achieve the above object, institute is the present invention using technical solution: a kind of steel pipe valve cutting formula soil anchor bolt anchor head, packet
The anchor pole wall formed by steel pipe is included, the anchor pole pars intramuralis is provided with steel strand wires or reinforcing bar, and anchor pole wall bottom is provided with pedestal,
The steel strand wires or reinforcing bar are connect with pedestal, and anchor pole wall lower part vertically offers multiple side through-holes formation steel discs and side is logical
The structure that hole is spaced apart.
The side through-hole is eight.
The nearly anchor pole wall bottom end face in side through-hole bottom end or to anchor pole wall bottom end face.
The steel disc top exterior walls circumferential direction cuts with notch I, and inner wall circumferential direction cuts with notch II in the middle part of steel disc.
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 construction party
Just, relatively inexpensive.
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 stress usage state diagram of the present invention.
In figure, steel pipe 1, steel strand wires 2, pedestal 3, steel disc 4, notch I 5, notch II 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. 2, a kind of steel pipe valve cutting formula soil anchor bolt anchor head is described including the anchor pole wall formed by steel pipe 1
Anchor pole pars intramuralis is provided with steel strand wires 2 or reinforcing bar.Anchor pole wall bottom is provided with pedestal 3, the steel strand wires 2 or reinforcing bar and pedestal
3 connections.Anchor pole wall lower part vertically offers multiple side through-holes and forms the structure that steel discs 4 and side through-hole are spaced apart, at this
Multiple side through-holes be three or three or more.
Referring to Fig. 1 to Fig. 3, further, the side through-hole is eight.
Referring to Fig. 1 to Fig. 3, further, the nearly anchor pole wall bottom end face in side through-hole bottom end or to anchor pole wall bottom
End surface.
Referring to Fig. 1 to Fig. 3, further, to guarantee 1 deformation of bottom direction of steel pipe and crooked place, the steel disc 4 is pushed up
Portion's outer wall circumferential direction cuts with notch I 5, and 4 middle part inner wall circumferential direction of steel disc cuts with notch II 6；So that steel disc 4 when deforming circumferentially
Bending at grooving.
This soil anchor bolt is put into anchor hole after anchor hole bottom hole completes drilling, reaming referring to Fig. 1 to Fig. 3, is used
Drawing instrument drawing steel stranded wire 2 makes 1 bottom of steel pipe that bending occur along the notch II 6 at 4 middle part of notch I 5 and steel disc at 4 top of steel disc
Deformation.Native country rockbolt installation is completed, grouting material is perfused into hole, maintenance is completed.
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.
