Abstract

The invention discloses a kind of construction ground anchorages, including anchor pile and anchorage bearing；Anchor pile includes being fixedly connected with anchorage bearing and the pile pipe of inner hollow and the anchoring mechanism being set in pile pipe, anchoring mechanism includes the claw of compression bar He at least one inverted l-shaped structure, when compression bar, which is operated, to be moved axially downwards along pile pipe, claw is forced to rotate around hinge joint for the free end cooperation in pile pipe lower end and portion anyhow so that the vertical portion of claw carries out retaining fixing to stretching outside pile pipe；When in use, pass through the compression bar of peripheral operation anchor pile, it moves axially downwards it free end in the portion anyhow of each claw is caused to oppress, each claw is forced to rotate around hinge joint, so that the vertical portion of each claw to form retaining fixing along extending radially out for pile pipe；Meanwhile anchorage bearing can be vibrated caused by external wind load or other load and be buffered, so that influence of the vibration to anchor pile caused by external load that decay, guarantees the intensity of its anchor force.

Description

Construction ground anchorage

Technical field

The present invention relates to the realm of building construction, in particular to a kind of construction ground anchorage.

Background technique

In construction site, anchor is needed to anchor some equipment temporarily set up, to guarantee that it is steady more Fixed work, guarantees operational security, such as in order to transport material up and down, need to set up derrick at the scene, when derrick is set up it is excessively high when Needing to be arranged cable rope drawknot just can guarantee its steady operation, and cable rope and ground connecting portion just need to pass through ground anchorage It realizes.In the prior art, cluster earth anchor, fine rod-type earth anchor and spiral earth anchor be common are, these ground anchor structures are usual General under state there is no problem, can be realized the purpose of protection equipment steady operation, but when encounter wind load it is excessive or other When load action, ground anchorage can generate shaking under the action of external loads and anchoring dynamics is died down, when serious even Ground anchorage is integrally pulled out, entirely ineffective to the anchoring of equipment, even will cause safety accident when dangerous

Therefore, it is necessary to be improved to existing construction with ground anchorage, making it have preferable performance can be supported The vibration that ant wind load or other loads generate guarantees to anchor firm power.

Summary of the invention

In view of this, the present invention provides a kind of construction ground anchorage, wind can be resisted with preferable performance The vibration that load or other loads generate guarantees to anchor firm power.

Construction ground anchorage of the invention, including for being inserted into the anchor pile anchored in ground and for solid The anchorage bearing determining anchor pile and the vibration of external load generation being buffered；Anchor pile includes and anchorage bearing is fixed and connected It connects and the pile pipe of inner hollow and the anchoring mechanism being set in pile pipe, anchoring mechanism includes compression bar and at least one inverted L-shaped knot The claw of structure, compression bar are set in pile pipe in a manner of it can be operated along pile pipe axial movement, are corresponded on the tube wall of pile pipe each Claw is equipped with a strip groove radially penetrated through, and each claw includes portion and vertical portion and anyhow portion and vertical portion anyhow Intersection forms hingedly point articulated be installed in corresponding strip groove；When compression bar, which is operated, to be moved axially downwards along pile pipe, stake Claw is forced to rotate around hinge joint for the free end cooperation in pipe lower end and portion anyhow so that the vertical portion of claw is to stretching out outside pile pipe Carry out retaining fixing.

Further, compression bar includes with the free end of portion anyhow of each claw supporting the only head that contacts and by can be in a manner of clutch With the compression bar ontology of head cooperation, the lower end of compression bar ontology is equipped with cavity, head top be inserted into cavity and with this bodily form of compression bar At axial limiting, it is provided in cavity when forcing claw under the driving of compression bar ontology for head around hinge joint rotation to head Form the helical spring of downward elastic pre-stress.

Further, the ontology 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 contacting the cambered surface of simultaneously rounding off with head.

Further, the ontology of head upwardly extends the guide part to be formed with the cooperation of the cavity of compression bar ontology, is formed in cavity There is the limited shoulder for forming axial limiting cooperation with guide part, the installation for installing helical spring is provided on guide part Column.

Further, spiral shell is set on inside pile pipe and is provided with internal screw thread, compression bar by can by operation turn in a manner of and spiral shell External threading cooperation.

Further, it is provided on the vertical portion of claw for improving the hangnail for fixing power.

Beneficial effects of the present invention: construction ground anchorage of the invention, anchor pile are mounted on anchorage bearing, In use, being anchored in anchor pile insertion ground, and anchorage bearing is consolidated by concrete foundation or external fixator It is fixed, then pass through the compression bar of peripheral operation anchor pile, moves axially downwards it and free end in the portion anyhow of each claw is made At compressing, each claw is forced to rotate around hinge joint, so that the vertical portion of each claw extending radially out along pile pipe, i.e., So that claw, which protrudes into soil, forms retaining fixing；Meanwhile anchorage bearing has antivibration effect, it can be to external wind load or other Vibration caused by load is buffered, so that influence of the vibration to anchor pile caused by external load that decay, guarantees its anchor force Intensity.

Detailed description of the invention

The invention will be further described with reference to the accompanying drawings and examples.
