Description
Technical field：
The present invention relates to curtain wall installing engineering field, refers in particular to the chemically expansible bolt used during a kind of curtain wall installation, tool
It is a kind of difunctional chemically expansible bolt that body, which is said,.
Background technology：
The wall metal bolts that usual building field commonly uses have physical expansion bolt, by wall body hole, then will be swollen
Quick-fried and tightening nut is pushed up in swollen bolt hammering, its surface external member jag, opening is formed reverse tapering and is produced breakout capacity, this spiral shell
Bolt will lose functional effect on the masonry wall of soft, crisp wall or Hollow brick, when bolt is arranged on wall reluctantly, use spanner
Nut is twisted, bolt will be screwed loosening quickly；The bolt that another kind generally uses is chemical bolt, after wall body hole, will be filled
Glass tube equipped with anchoring adhesive first pushes away in manhole or anchoring adhesive is directly injected into hole, then by solid screw insertion hole, passes through
Anchoring adhesive combines by steel nail and wall hole wall and produces bond stress, purely screw is produced anti-pulling by the glued power of anchoring adhesive
Power, the defects of this bolt is present are that anchoring adhesive tends not to uniform complete parcel bolt and wall hole wall and bonded, while such as
In the case of fruit has continuous electric welding, the adhesive property that will be easy to make anchoring adhesive cause anchoring adhesive because temperature significantly raises decline or
Failure, produce potential safety hazard.
The content of the invention：
It is an object of the invention to overcome the deficiencies in the prior art, there is provided one kind has expansion bolt function again simultaneous
Difunctional bolt with chemical bolt function, and the jag part of barb is formed with bolt tail jag part, by beating
Hit bolt and be oriented to the quick-fried cone post in top, promote bolt jag barb afterbody volume expansion, bolt produces stronger antibody pull out force in wall, entered
And after bolt tube chamber injection anchoring adhesive, then steel column will be injected and promote tube chamber, intraluminal bar planting glue fills up under pressure
All gaps between bolt and wall, the bond stress of bar planting glue is set to reach maximum.
The present invention solves the following technical scheme that above-mentioned technical problem uses：
A kind of difunctional chemically expansible bolt, it includes bolt body (1), cone (2), injects steel column (3), expands
Pitch (4), plastic emitting slotted eye (5)；It is characterized in that：Described bolt body (1) is designed to hollow tubular structure and tube wall is provided with trellis
The slotted eye of slotted eye or other forms, the afterbody of bolt body (1) are provided with some expansion jags (4), and bolt body (1) afterbody is furnished with
One quick-fried cone in guiding top (2) for being set as concentric reducer, front end are provided with some plastic emittings equipped with an injection steel column (3) in tube wall
Slotted eye (5).
Preferably, the afterbody of bolt body (1) is provided with several barbs.
Preferably, bolt body (1) afterbody is oriented to concentric reducer equipped with one and pushes up quick-fried cone (2), top major part
Body diameter consistent with bolt body (1) diameter is optimal body diameter, and microcephaly's body diameter omits than the internal diameter of bolt body (1)
It is small be it is optimal,
Preferably, bolt body (1) afterbody is oriented to equipped with concentric reducer pushes up quick-fried cone (2) total length than bolt body (1)
Afterbody be provided with it is some expansion short more than 5 millimeters of jag (4) total lengths be optimal.
Preferably, institute's grooved bore total surface area occupies whole root canal wall total surface area more than 25% on bolt body (1)
Most preferably.
Preferably, bolt body (1) is designed to center outer surface knurling mat surface.
Beneficial effect of the present invention：It is to provide a kind of difunctional chemically expansible bolt, bolt passes through anchoring adhesive, afterbody jag quilt
Push up quick-fried expansion and barb while act on, bolt is had the dual-use function of chemical bolt and physical expansion bolt concurrently, after testing in reality
Used in the masonry wall of heart brick (aerated bricks), the tension pull out force of bolt can reach more than 1500 kilograms, in cutting for reinforced concrete
Used on power wall or beam column, the tension pull out force of bolt is up to more than 2500 kilograms, can substitute traditional curtain wall built-in fitting completely
(the tension pull out force of national standard built-in fitting is more than 2000 kilograms), it is public that tension pull out force 1000 is can reach on brickwork wall
It is more than jin.
Brief description of the drawings：
Fig. 1 is a kind of structural representation of difunctional chemically expansible bolt of the present invention；
Fig. 2 is a kind of structural decomposition diagram of difunctional chemically expansible bolt of the present invention.
Embodiment：
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, including bolt body (1), cone (2), injection steel column (3), expansion jag (4), plastic emitting slotted eye
(5)；It is characterized in that：Described bolt body (1) is designed to hollow tubular structure and tube wall is provided with trellis slotted eye or other forms
Slotted eye, the afterbody of bolt body (1) is provided with some expansion jags (4), and bolt body (1) afterbody is set as concentric reducer equipped with one
The quick-fried cone in guiding top (2), front end equipped with one injection steel column (3), be provided with some plastic emitting slotted eyes (5) in tube wall, act on
During hollow brick wall, because the general 2.0~2.5cm of the thickness of the anticracking grout coat of plaster of wall is thick, the wall thickness of hollow brick typically exists
More than 2.0cm, using the length of appropriate centrum handle, poroid, other parts that 4.0~5.0cm of screw front end makes cell in part
Solid wall pipe is formed, injection nail radius is the half of bolt radius, and coarse knurling face, energy and glue production are made in hollow pipe nail outer surface
Raw stronger bonding force, and afterbody jag just possesses physical expansion anti-pulling ability, and the barb member of jag afterbody make Guan Ding and
Wall hole produces stronger hook pulling force, and by hollow pipe nail push-in hole, hammering top is quick-fried, then anchoring adhesive is noted for drilling on wall
Enter in Guan Ding tube chamber, then by the tube chamber for injecting steel column push-in Guan Ding, hollow nail is become solid nail again, make glue in wall
Reach full irrigation in hole.Bar planting glue forms tree root with wall hole wall by Guan Ding notch and connected, while Guan Ding solid tube wall
Mat surface and porthole hole wall form effective bonding, so, overall Guan Ding passes through bar planting glue and afterbody reverse tapering
Jag barb generates the dual-use function of physical expansion bolt and chemical bolt simultaneously, after testing in the block of solid brick (aerated bricks)
Being used in body wall, the tension pull out force of bolt can reach more than 1500 kilograms, be used on the shear wall or beam column of reinforced concrete,
The tension pull out force of bolt is up to more than 2500 kilograms, can substitute completely traditional curtain wall built-in fitting (national standard built-in fitting
Tension pull out force is more than 2000 kilograms), tension pull out force is can reach on brickwork wall more than 1000 kilograms；It is steady so as to reach
Gu, safety purpose.
One kind of embodiment described above, simply more preferably embodiment of the invention, those skilled in the art
The usual variations and alternatives that member is carried out in the range of technical solution of the present invention should all include within the scope of the present invention.
