Abstract
The invention discloses a ground anchor device for building construction. The ground anchor device for the building construction comprises an anchoring pile and an anchoring supporting seat, wherein the anchoring pile comprises a hollow pile pipe which is fixedly connected with the anchoring supporting seat, and an anchoring mechanism arranged in the pile pipe; the anchoring mechanism comprises a pressing rod, and at least one inverted L-shaped clamping claw; when the pressing rod is operated to axially downwards move along the pile pipe, the lower end of the pile pipe is in match with a free end of a transverse straight part so as to drive each clamping claw to rotate around a hinging point until a vertical part of each clamping claw extends out of the pile pipe to achieve backing stopping and clamping and fixing; when in use, the pressing rod of the anchoring pile is operated from outside and axially downwards moves to press the free end of the transverse straight part of each clamping claw, thus each clamping claw can rotate around the hinging point, and the vertical part of each clamping claw can radially outwards extend along the pile pipe so as to achieve backing stopping and clamping and fixing; meanwhile, the vibration caused by external wind load or other load can be buffered through the anchoring supporting seat, so that the influence of the vibration caused by the external load on the anchoring pile can be reduced, and as a result, the strength of the anchoring force can be ensured.
Description
Technical field
The present invention relates to the realm of building construction, more particularly to a kind of construction ground anchorage.
Background technology
In construction site, need anchor to anchor the equipment that some are set up temporarily, to ensure which is steady more
It is fixed to work, it is ensured that operational security, such as in order to transport material up and down, derrick need to be set up at the scene, when derrick is set up it is too high when
Need setting cable rope drawknot just to can guarantee that its steady operation, and cable rope is accomplished by by ground anchorage with ground connecting portion
Realize.In prior art, cluster earth anchor, fine rod-type earth anchor and spiral earth anchor are common are, these ground anchor structures are usual
Typically have no problem under state, can realize the purpose of protection equipment steady operation, but when run into wind load it is excessive or other
During load action, ground anchorage can be produced in the presence of external loads and be rocked and so that anchoring dynamics dies down, when serious even
Ground anchorage is integrally pulled out, and the anchoring to equipment is entirely ineffective, even can cause security incident when dangerous
Accordingly, it would be desirable to be improved with ground anchorage to existing construction so as to can support with preferable performance
The vibration that ant wind load or other loads are produced, it is ensured that the firm power of anchoring.
The content of the invention
In view of this, the present invention provides a kind of construction ground anchorage, and there is preferable performance can resist wind for which
The vibration that load or other loads are produced, it is ensured that the firm power of anchoring.
The construction ground anchorage of the present invention, including for inserting the anchor pile that anchored in ground and for solid
Determine anchor pile the anchorage bearing vibrated into row buffering that can be produced to external load；Anchor pile is included being fixed with anchorage bearing and is connected
Connect and the pile pipe of inner hollow and the anchoring mechanism being arranged in pile pipe, anchoring mechanism includes depression bar and at least one inverted L-shaped knot
The claw of structure, depression bar are arranged in pile pipe in the way of it can be operated along pile pipe axial movement, and on the tube wall of pile pipe, correspondence is each
Claw is provided with the bar-shaped trough of a radial direction insertion, and each claw includes portion anyhow and vertical portion and portion and vertical portion anyhow
Intersection forms and is hinged point articulated being installed in corresponding bar-shaped trough；When depression bar is operated to be moved axially downwards along pile pipe, stake
Pipe lower end is coordinated with the free end in portion anyhow forces claw to rotate so that the vertical portion of claw is stretched out to the outside of pile pipe around pin joint
Carry out retaining fixing.
Further, depression bar includes supporting the head that only contacts with the free end of portion anyhow of each claw and by can be in the way of clutch
The depression bar body coordinated with head, the lower end of depression bar body are provided with cavity, in head top insertion cavity and with this bodily form of depression bar
Into axial limiting, be provided with cavity for head force under the driving of depression bar body claw around pin joint rotate when to head
Form the helical spring of downward elastic pre-stress.
Further, the body of head is up big and down small circular cone header structure, and the free end of portion anyhow of each claw is formed with
For the cambered surface of simultaneously rounding off is contacted with head.
Further, the body of head upwardly extends the guide part to be formed with the cavity cooperation of depression bar body, is formed in cavity
Have for the limited shoulder that axial limiting coordinates being formed with guide part, be provided with for installing the installation of helical spring on guide part
Post.
Further, swivel nut is arranged on inside pile pipe and is provided with internal thread, depression bar by can by operation turn in the way of and spiral shell
External threading coordinates.
Further, it is provided with the vertical portion of claw for improving the hangnail for fixing power.
Beneficial effects of the present invention：The construction ground anchorage of the present invention, anchor pile are arranged on anchorage bearing,
During use, anchor pile insertion is anchored in ground, and anchorage bearing is carried out by concrete foundation or external fixator solid
It is fixed, then by the depression bar of peripheral operation anchor pile so as to make the free end for moving axially downwards the portion anyhow to each claw
Into compressing, each claw is forced to rotate around pin joint so that the vertical portion of each claw extending radially out along pile pipe, i.e.,
So that claw forms retaining in stretching into soil fixing；Meanwhile, there is anchorage bearing antivibration to act on, can to outside wind load or other
Row buffering is entered in the vibration that load is caused, impact of the vibration caused so as to external load of decaying to anchor pile, it is ensured that its anchor force
Intensity.
