Description
Technical field
The invention belongs to construction and installation component technology field, be applicable under water or the template of concrete structure reinstatement works or support fixing under tide environment, particularly a kind of EXPANSION ANCHOR BOLTS that can remove completely and assembly and disassembly methods thereof.
Background technique
Conventional EXPANSION ANCHOR BOLTS utilizes end wedge configuration, and by the relative movement of screw rod and sleeve pipe, wedge shape struts sleeve bottom, realizes sleeve pipe and contacts with the effective of structure hole wall, thus provides the anti-pulling ability of screw rod.
But because sleeve pipe is squeezed end gross distortion, cannot normally take out, and the minimum circumscribed circle diameter of screw rod end wedge shape is greater than the inner diameter not being out of shape anterior cannula, just because of sleeve pipe cannot take out, directly causes screw rod also cannot take out.In the past when repairing under water or have the concrete structure of tidal effect surperficial, need at its surperficial fixed die plate, employing EXPANSION ANCHOR BOLTS is fixedly the method for the most frequently used also most convenient, and the consumption of EXPANSION ANCHOR BOLTS is many toward contact, but the EXPANSION ANCHOR BOLTS of routine just can not be removed after a procedure.Gap between screw rod and sleeve pipe cannot effectively shutoff, although concrete structure is the defect area fixed, has manufactured again the passage that some extraneous corrosive mediums invade structure inside in repair process.
Installation form the most frequently used, the most easy method when since EXPANSION ANCHOR BOLTS is local defect of concrete reparation, that is just necessary to develop a kind of EXPANSION ANCHOR BOLTS that can remove smoothly after a procedure very much, cannot take out to make up existing EXPANSION ANCHOR BOLTS the problem brought.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of by setting up expansion sleeve, and locking mechanism is set respectively, to realize the overdose space increasing dismounting flexibly, reach the EXPANSION ANCHOR BOLTS that can remove completely and the assembly and disassembly methods thereof of the reverse dismounting operation after assembling of expanding.
Object of the present invention realizes by following technical proposal: a kind of EXPANSION ANCHOR BOLTS that can remove completely, comprise screw rod, described screw rod is the cylindric body of rod of variable cross section, the small end of the body of rod is fastening screw rasp bar, the large end of the body of rod arranges the dovetail post of tapered, the body of rod is arranged expansion screw section, described screw rod periphery socket inner sleeve, the tail end of described inner sleeve offers some interior stern notches vertically, the tail end of inner sleeve is divided into several interior swollen bar by interior stern notch, the inner circle wall of described inner sleeve is arranged assembling thread section, assembling thread section and expansion screw section form screw-thread fit, the head end of described inner sleeve is offered some interior pulling eyes, the periphery socket outer sleeve of described inner sleeve, the tail end of described outer sleeve offers some outer stern notches vertically, the tail end of outer sleeve is divided into several outer swollen bar by outer stern notch, the head end of described outer sleeve is offered some outer pulling eyes, also comprise fastening cover, the described fastening enclosure is connected on outer sleeve, on the head end of inner sleeve and screw rod, the fastening screw rasp bar of described screw rod overlaps connected nut.
Originally in the EXPANSION ANCHOR BOLTS can removed completely, screw rod is specially variable cross section rod-like structure, and its one end circular diameter is large, and as tail end, the other end circular diameter is little, and as head end, intermediate, inclined transition forms certain taper.The dovetail post of taper platform shape, its path end face is connected the tail end of screw rod, and outside its bigger diameter end faces, overall and screw coaxial line is arranged.The position of expansion screw section is near dovetail post, and expansion screw section has 2 ~ 4 circle screw threads, and the external diameter of expansion screw section is greater than the external diameter of fastening screw rasp bar.Some interior stern notch on inner sleeve is evenly distributed, and make the width of interior swollen bar consistent, the some outer stern notch on outer sleeve is evenly distributed, and make the width of outer swollen bar consistent, in addition, the length of swollen bar is less than the length of outer swollen bar.The head end of inner sleeve offers two interior pulling eyes relatively, being convenient to clamp inner sleeve, preventing the inner sleeve when rotational lock from following rotation, conveniently being pulled out by inner sleeve when removing by interior pulling eye.Outer sleeve be shorter in length than inner sleeve, the head end of outer sleeve offers two outer pulling eyes relatively, by outer pulling eye be convenient to clamp outer sleeve, be convenient to rotate and remove time outer sleeve is pulled out.
In the above-mentioned EXPANSION ANCHOR BOLTS that can remove completely, the screw thread of described expansion screw section screws direction and the screw thread of fastening screw rasp bar, and to screw direction contrary.In expansion screw section and fastening screw rasp bar, one is left-handed thread, and another one is right-handed thread, to ensure when tightening nut, prevents screw rod from getting loose with being threaded of inner sleeve.
