Description
Technical field
The invention belongs to building anchor bolt technical fields, more particularly to a kind of gluing mould base expanding and base expanding anchor bolt and its application method.
Background technique
For concrete structure anchor bolt, American-European aspect has extremely successful experience, phase of the China for concrete anchor
It should design, also be gradually improved using specification, but existing anchor bolt fixed form is all relatively simple or be mechanically fixed, and such as expands
Anchor bolt, base expanding and base expanding anchor bolt cut bottom anchor bolt or are chemical anchor bolts, and single fixed form determines that the reliability of anchoring system is inclined
Low, chemistry, which is fixed and is mechanically fixed, respectively superiority and inferiority, if can combine the advantages of the two, can reach safer fixation
Purpose.
Therefore, European ETAG (European Technical specification) is referred to " gluing mould base expanding and base expanding " anchor bolt, but european norm is to such anchor
Bolt is also only to mention once, does not elaborate, and there is no indicate specific anchor bolt construction in detail.Current Chinese code of practice, such as
GB50367-2013 " concrete structure reinforcement design specification " is also only to provide schematic illustration to such anchor bolt, is not given
Specific structural map out.This anchor bolt encounters following problem in engineering practice:
1, the tapered cup nut fixing end of the screw portion of anchor bolt and anchor bolt bottom, the two rotates synchronously during installation, causes
The locking key of mould base expanding and base expanding can not fully open, and mould base expanding and base expanding fixed function is difficult to realize；
2, such as make screw rod and the tapered cup nut not transfer of anchor bolt bottom end, then should expand mould base expanding and base expanding locking key outer diameter or expand bottom
However, so doing, and there is " piston effect ", thing so that they and concrete hole wall are adjacent in portion's cone nut fixing end outer diameter
Anchor-holding material in first injection hole is squeezed out when installing anchor bolt by anchor bolt completely, cannot achieve real " gluing " function, or
Though person, without squeezing out completely, the damping action of anchor-holding material is too strong, mould base expanding and base expanding locking key is difficult to correctly in place, cannot achieve
" mould base expanding and base expanding " function, it may be assumed that between two functions of mould base expanding and base expanding and gluing, have too many difficulties to cope with, attend to one thing and lose sight of another.
3, it when gluing mould base expanding and base expanding anchor bolt is installed, even if solving the problems, such as above-mentioned " transfer " or " piston effect ", is also not easy
Solve the problems, such as that the longitudinal central axis line in anchor bolt longitudinal central axis line and the hole held successfully in advance in concrete is corresponding (hereinafter referred to as " right
In "), cause mould base expanding and base expanding locking key undesirable in place, and then influence the fixed effect of such anchor bolt.
It should realize " mould base expanding and base expanding ", realize " gluing " again, also want the requirement of " centering ", the contradiction between these three purposes
It is very sharp.The purpose of the present invention seeks to solve a series of this contradiction, and providing one kind can be convenient installation, fixed reliable glue
Sticking to mould base expanding and base expanding anchor bolt.
Summary of the invention
The purpose of the present invention is to provide a kind of gluing mould base expanding and base expanding anchor bolts, by the way that outer-hexagonal mounting head, locating piece, mould is arranged
Base expanding and base expanding locking key, combination cone nut and tapered plug are fitted tightly over tapered plug on the bottom wall of hole by tapping outer-hexagonal mounting head, combine cone nut
It is opened along tapered plug, by rotation outer-hexagonal mounting head, opens mould base expanding and base expanding latch fitting under the promotion of retaining ring along combination cone nut,
The requirement for realizing " mould base expanding and base expanding ", " gluing " and " centering " is solved and is now come up against a series of problems in engineering practice.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:
The present invention is a kind of gluing mould base expanding and base expanding anchor bolt, including screw rod, is equipped with external screw thread on the both ends pole face of the screw rod,
The end point of one male end of screw rod be equipped with outer-hexagonal mounting head, screw rod be successively arranged along its length hex nut, washer,
Locating piece, retaining ring, the locking key of mould base expanding and base expanding and combination cone nut；
The hex nut, washer and locating piece are threaded in screw rod on the external screw thread of outer-hexagonal mounting head；
