Description
Technical field
The utility model relates to ground anchorage field, particularly relates to a kind of Wedge-type Inner bolt head, is specifically applicable to provide mechanical anchoring force on the basis of script chemical grouting anchored force.
Background technology
Developing rapidly of ground anchorage is closely related with Anchorage Technology progress, in recent years, China's Anchorage Technology obtains and develops fast, particularly apply very wide in civilian construction basement anti-floating engineering, but the anchorage style of traditional conventional common bolt be rely on grouting material solidification after shear strength and adhesion stress to provide anchored force, because grouting material exists problem of aging, grouting body in order to ensure anchoring section has enough anchored force, often needs anchor pole to anchor into the degree of depth larger in rock or concrete.
Summary of the invention
The purpose of this utility model overcomes single, the not ageing-resistant problem of the anchored force that exists in prior art, provides a kind of and utilize the mechanical snap power at the bottom of hole to carry out anchoring, safe and reliable Wedge-type Inner bolt head.
For realizing above object, the technical solution of the utility model is as follows:
A kind of Wedge-type Inner bolt head, multiple voussoirs that this Inner bolt head comprises anchor pole, arrange around the outer wall border of anchor pole, the voussoir seat being set in anchor pole outside, side and the anchor pole of the nearly outer wall in bottom of described voussoir are hinged, described voussoir seat is positioned at the below of voussoir, its end face comprises the inclined-plane, horizontal plane, No. two inclined-planes that connect successively, and an inclined-plane, No. two inclined-planes are symmetricly set on the both sides of horizontal plane, the angle that the axis of inclined-plane, No. two inclined-planes and an anchor pole is formed is acute angle.
Described anchor pole extends to the outside of voussoir seat after passing voussoir seat via horizontal plane.
Compared with prior art, the beneficial effects of the utility model are:
1, a kind of Wedge-type Inner bolt head of the utility model comprises anchor pole, around multiple voussoirs that the outer wall border of anchor pole is arranged, be set in the voussoir seat of anchor pole outside, side and the anchor pole of the nearly outer wall in bottom of voussoir are hinged, the end face being positioned at the voussoir seat below voussoir comprises the inclined-plane connected successively, horizontal plane, No. two inclined-planes, during use, the anchor pole of this Inner bolt head is inserted in boring, when voussoir hinged on anchor pole arrives the tapered portion of boring, voussoir can externally open under gravity, its bottom surface is close to an inclined-plane or No. two inclined-planes, the inverted cone surface forming up big and down small conehead face and boring is adjacent to, the mechanical snap power at the bottom of hole is utilized to carry out anchoring, this kind of anchored force solidify with inorganic bond pouring material after adhesion stress combine, define a kind of safe and reliable, the anchorage style of good endurance, the drilling depth of anchor pole can not only be reduced, be applicable to high temperature, the environment of high humility, and without the need to exerting pressure during assembling.Therefore, the utility model is safe and reliable, good endurance not only, and can reduce the drilling depth of anchor pole, without the need to exerting pressure during assembling.
2, in a kind of Wedge-type Inner bolt head of the utility model, anchor pole is via horizontal plane through the outside extending to voussoir seat after voussoir seat, and during use, this structure can reserve enough spaces for the perfusion of inorganic cementitious material, is conducive to the anchored force ensureing Inner bolt head.Therefore, the utility model is conducive to the anchored force ensureing Inner bolt head.
