Abstract
The utility model discloses a kind of back of the body bolt, including dormant bolt, bolt sleeve is socketed on the screw rod of dormant bolt, one end of bolt sleeve arranges expansion loop, described expansion loop is arranged on bolt sleeve near one end of dormant bolt head, and the end opening angle of expansion loop is less than the taper of dormant bolt head.The every a piece of of described expansion loop is connected with bolt sleeve by foil.Also include that hex nut, described hex nut are arranged on the screw rod of dormant bolt, the female thread with threaded adapter on screw rod is set in hex nut.Pad is set between hex nut and bolt sleeve.The pad is plastic spacer or metallic gasket.Compared with prior art, expansion loop is combined this utility model by which with bolt sleeve, and its globality is stronger, and pushes expansion loop open larger angle using dormant bolt, and its coefficient of expansion is big, very high with the conjugation that groove is expanded in back of the body bolt bottom.
Description
Technical field
This utility model is related to building decoration field, specifically, is a kind of back of the body bolt of stone material.
Background technology
In building stone curtain wall dried hanging construction technology, back of the body bolt system is increasingly subject to people with safe and reliable performance
Accreditation, progressively promote the use of in building decoration field.The various back of the body bolt for commonly using on the market at present mostly is expansion type structure,
But expansion type back of the body bolt has that the coefficient of expansion is little, low with the conjugation that back of the body bolt bottom hole portion expands groove, the feelings of false anchoring can occur often
Condition；Bad control, the careless slightly result for easily producing prominent destruction panel is operated in installation exercise.It is simultaneously used in high level
Architectural, as by earthquake and all the time positive and negative wind load is acted on, back of the body bolt and bottom hole, the hard contact of hole wall are long and long
Occur that powder and chipping phenomenon, back of the body bolt screens are easily produced to drag of anchor and release danger.
Content of the invention
The purpose of this utility model is to provide a kind of simple structure, easy for installation, unstressed to stone material plaque, lossless
Wound, is provided simultaneously with good, the safe and reliable back of the body bolt of anti-seismic performance.
This utility model is realized using following technological means：A kind of back of the body bolt, including dormant bolt, dormant bolt screw rod
Upper socket bolt sleeve, one end of bolt sleeve arrange expansion loop, and described expansion loop is arranged on bolt sleeve near dormant bolt head
One end, the taper of the end opening angle of expansion loop less than dormant bolt head.
The every a piece of of described expansion loop is connected with bolt sleeve by foil.
Also include that hex nut, described hex nut are arranged on the screw rod of dormant bolt, arrange in hex nut
Female thread with threaded adapter on screw rod.
Pad is set between hex nut and bolt sleeve.
The pad is plastic spacer or metallic gasket.
Compared with prior art, expansion loop is combined this utility model by which with bolt sleeve, and its globality is stronger, and using heavy
Hook bolt pushes expansion loop open larger angle, and its coefficient of expansion is big, very high with the conjugation that groove is expanded in back of the body bolt bottom.
Description of the drawings
Fig. 1 is this utility model structural representation.
Wherein 1- dormant bolts, 2- dormant bolt heads, 3- bolt sleeves, 4- expansion loops, 5- hex nuts, 6- pads.
Specific embodiment
This utility model is described in further detail with reference to Figure of description：
This utility model is related to a kind of fixing device of building exterior wall face, specifically, is that one kind is filled used in fixing stone
The back of the body bolt of plaque, it include a dormant bolt 1, are threaded on the screw rod of dormant bolt.The side of countersunk head screw rod is arranged
Dormant bolt head 2, the width of described head are less than the diameter of straight hole on stone material.
On dormant bolt, a bolt sleeve 3 is provided with, specifically, described bolt sleeve 3 is socketed in dormant bolt 1
Screw rod on, the internal diameter of bolt sleeve 3 is equal or slightly larger than the diameter of screw rod 1, in this utility model, one end of the bolt sleeve 3
Be additionally provided with expansion loop 4, specifically, expansion loop 4 arranges at least 3 expansion pieces, per a piece of expansion piece by foil with
Bolt sleeve 3 connects, and expansion piece cooperates becomes an annular.
In this utility model, described expansion loop 4 is arranged on bolt sleeve 3 near the side of dormant bolt head 2, concrete next
Say, in the upside of its dormant bolt head 2, the opening angle of expansion loop 4 is less than dormant bolt head 2 for described expansion loop 4
Taper, therefore in the case of 4 non-stress of expansion loop, the bottom of expansion loop 4 ride on dormant bolt head 2 and prevented by which after
Continue and move down.
When stress on bolt sleeve 3 is moved down, the expansion loop 4 on bolt sleeve 3 is moved to 2 direction of dormant bolt head
Dynamic, as the taper of dormant bolt head 2 is more than the opening angle of expansion loop 4, then in the presence of dormant bolt head 2, swollen
Tensioner ring 4 is rapidly flared out, and snaps in the wedged hole arranged on stone material, reaches the effect of fixing stone.
In this utility model, also include that a hex bolts 5, the hex bolts 5 are arranged on 3 top of bolt sleeve, pass through
Rotation hex bolts 5 to apply pressure to bolt sleeve 3, between hex bolts 5 and bolt sleeve 3, is provided with pad 6, this practicality
In new, pad 6 is using plastic spacer or metallic gasket, the pad that also can be made using other materials according to actual requirement.
