Abstract
A sleeve-type inside anchor comprises an anchor rod and a sleeve. The anchor rod comprises a straight portion and a frustum portion. A small diameter end of the frustum is fixedly connected with one end of the straight portion. The sleeve sleeves the straight portion. A plurality of kerfs are circumferentially formed in the end, close to the small diameter end, of the sleeve. The sleeve-type inside anchor is safe, reliable, durable and wide in application range.
Description
Technical field
The present invention relates to ground anchorage field, particularly relate to a kind of telescopic Inner bolt head, be 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 object of the invention is to overcome the problem that the anchored force that exists in prior art is single, not ageing-resistant, provide a kind of and utilize the mechanical snap power at the bottom of hole to carry out anchoring, the telescopic Inner bolt head of safe and reliable modified.
For realizing above object, technical scheme of the present invention is as follows:
A kind of telescopic Inner bolt head, this Inner bolt head comprises anchor pole, sleeve, described anchor pole comprises straight-bar portion, prismoid section, the smaller diameter end of prismoid section is fixedly connected with the one end in straight-bar portion, jacket casing is located at the outside in straight-bar portion, and the end opens of nearly smaller diameter end has multiple joint-cutting on sleeve, the plurality of joint-cutting is arranged along the border of end.
Compared with prior art, beneficial effect of the present invention is:
1, in a kind of telescopic Inner bolt head of the present invention, anchor pole comprises straight-bar portion, prismoid section, the smaller diameter end of prismoid section is fixedly connected with the one end in straight-bar portion, jacket casing is located at the outside in straight-bar portion, and the end opens of nearly smaller diameter end has multiple joint-cutting on sleeve, during use, sheathed sleeved anchor pole is inserted in boring, by to sleeve axial pressure, make sleeve under the guide effect of the male cone (strobilus masculinus) of prismoid section along joint-cutting distending, the conical surface forming lower large little conehead face and foot of hole is adjacent to, the mechanical snap power of foot 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 can very according to needing the manufactured materials selecting sleeve, the scope of application is wider.Therefore, the present invention is safe and reliable, good endurance not only, and the scope of application is wider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is scheme of installation of the present invention.
In figure: anchor pole 1, straight-bar portion 11, prismoid section 12, smaller diameter end 121, male cone (strobilus masculinus) 122, sleeve 2, end 21, joint-cutting 22, conehead face 3.
Detailed description of the invention
Illustrate that the present invention is further detailed explanation with detailed description of the invention below in conjunction with accompanying drawing.
See Fig. 1, Fig. 2, a kind of telescopic Inner bolt head, this Inner bolt head comprises anchor pole 1, sleeve 2, described anchor pole 1 comprises straight-bar portion 11, prismoid section 12, the smaller diameter end 121 of prismoid section 12 is fixedly connected with the one end in straight-bar portion 11, sleeve 2 is set in the outside in straight-bar portion 11, and on sleeve 2, the end 21 of nearly smaller diameter end 121 offers multiple joint-cutting 22, and the plurality of joint-cutting 22 is arranged along the border of end 21.
Embodiment 1:
See Fig. 1, Fig. 2, a kind of telescopic Inner bolt head, this Inner bolt head comprises anchor pole 1, sleeve 2, described anchor pole 1 comprises straight-bar portion 11, prismoid section 12, the smaller diameter end 121 of prismoid section 12 is fixedly connected with the one end in straight-bar portion 11, sleeve 2 is set in the outside in straight-bar portion 11, and on sleeve 2, the end 21 of nearly smaller diameter end 121 offers multiple joint-cutting 22, and the plurality of joint-cutting 22 is arranged along the border of end 21.
During assembling, first on rock, bore straight hole with rig, after arriving design hole depth, reaming is carried out at the boring end with reaming bit, then the anchor pole 1 being arranged with sleeve 2 is inserted in the boring after reaming, subsequently axial pressure is carried out to sleeve 2, make sleeve 2 under the guide effect of the male cone (strobilus masculinus) 122 of prismoid section 12 along joint-cutting 22 distending, and move down gradually, form lower large little conehead face 3 and be adjacent to the conical surface of foot of hole.
