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 hex nut, described hex nut is arranged on the screw rod of dormant bolt and hex nut is fixedly installed with bolt sleeve, the female thread with threaded adapter on screw rod is set in hex nut.Groove is set in the screw tip of dormant bolt, the groove is arranged along the diametric(al) of screw rod cross section.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

A kind of back of the body bolt
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 and hex nut and bolt sleeve It is fixedly installed, the female thread with threaded adapter on screw rod is set in hex nut.
Groove is set in the screw tip of dormant bolt, the groove is arranged along the diametric(al) of screw rod cross section.
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- grooves.
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 fixedly installed on 3 top of bolt sleeve, Pressure is applied to bolt sleeve 3 by rotating hex bolts 5, in this utility model, can also make hex bolts 5 and bolt sleeve 3 pass through Pad is fixedly connected, and pad is using plastic spacer or metallic gasket, the pad that also can be made using other materials according to actual requirement Piece.
Screw tip described in the utility model arranges fluted 6, and the groove 6 is set along the diametric(al) of screw tip Put, the purpose for arranging groove is to go deep into preventing screw rod to revolve in groove 6 therewith with screwdriver when hex bolts 5 is rotated Turn, so as to improve the efficiency of fixing stone.
