It is adopt following technological scheme to realize that the present invention solves its technical problem:
A kind of detachable EXPANSION ANCHOR BOLTS external member repeating to be suitable for provided by the invention, comprise expansion sleeve, bolt and the nut suitable with this bolt, bolt comprises square toes, flat conehead, thread spindle and optical axis, pad is provided with between nut and expansion sleeve, the sleeve pipe of hollow cylindrical is provided with in expansion sleeve one end, the opening-like outer ring of the expansion sleeve the other end arranges intumescent sheet, inner ring is provided with inner convex platform, breach is provided with in the middle of sleeve pipe and inner convex platform, bolt is arranged in expansion sleeve, bolt one end is square toes, the other end is flat conehead, flat conehead and intumescent sheet are corresponding in the same side to be arranged, the plane of square toes is corresponding with flat conehead plane, square toes one end of bolt is through expansion sleeve, axis body near square toes one terminal bolt is provided with screw thread and forms thread spindle, thread spindle is provided with nut and pad successively.
In the present invention, in expansion sleeve, the diameter of breach is greater than the diameter of bolt.
In the present invention, the head of flat conehead is the solid flat cone-shaped of the opposite sex, and the diameter of flat conehead is greater than the maximum inner diameter of inner convex platform.
In the present invention, the opening shape of expansion sleeve is micro-horn-like, and inner convex platform is used for matching with the special-shaped head of flat conehead, is convenient to flat conehead and opens along inner convex platform is stressed.
When being suitable for a kind of detachable EXPANSION ANCHOR BOLTS external member repeating to be suitable for provided by the invention and installing, first punch on body of wall, its degree of depth exceedes EXPANSION ANCHOR BOLTS length, is alignd by flat for bolt conehead with intumescent sheet on expansion sleeve, fastening nut slightly, makes bolt can not rotate in expansion sleeve.EXPANSION ANCHOR BOLTS squeezed in hole, expansion sleeve is concordant with the face of body of wall.Use spanner fastening nut, bolt is pulled, and the flat conehead of its afterbody is drawn in expansion sleeve, and the intumescent sheet of expansion sleeve is pushed open by flat conehead, makes it be pressed into hole wall, and now, EXPANSION ANCHOR BOLTS is fixed on body of wall.
When being suitable for a kind of detachable EXPANSION ANCHOR BOLTS external member repeating to be suitable for provided by the invention and dismantling, first use spanner to remove nut, remove pad, with the square toes of hammer bolt, make the flat conehead of bolt tail end exit expansion sleeve, pull square toes with spanner, make its 90-degree rotation; Now the breach of the flat conehead of bolt tail end and expansion sleeve is equidirectional, pulls bolt, and flat conehead enters breach, and intumescent sheet recovers shape by External Force Acting, and flat conehead is stuck on inner convex platform, drives expansion sleeve to be together drawn out body of wall with bolt.
the beneficial effect that the present invention reaches:
(1)the detachable EXPANSION ANCHOR BOLTS external member repeating to be suitable for provided by the invention is mainly used in fastening metope in construction, can reuse, solution construction cost is high, the inaesthetic problem of body of wall, for subsequent construction provides the EXPANSION ANCHOR BOLTS that can reuse, for Component manufacture field, there is practicability widely.
(2)a kind of detachable EXPANSION ANCHOR BOLTS external member repeating to be suitable for provided by the invention is that a kind of making is simple, strong operability, reusable EXPANSION ANCHOR BOLTS external member.
