Abstract
The present invention relates to a kind of high power anchor bolt, belong to the architectural decoration technical field of fastening.This crab-bolt comprises cone headed screw rod, is enclosed within sleeve, the packing ring between screw head and sleeve on the screw rod, screws the nut on screw rod, and its improvements are: described sleeve is shaped on external screw thread, is rotary with the pressure holding nut on the described external screw thread.Crab-bolt of the present invention not only can be fixed in the sheet material as original crab-bolt very easily, and can after fixing the pressure holding nut be screwed, and is pressed in plate surface.When being subjected to impacting, the impact force that originally acted at the bottom of the hole is transferred to plate surface, and by the nut with larger sectional area, stress is disperseed, thereby solve the problem that prior art exists, the screw rod that various factors causes in the time of can avoiding because of punching simultaneously rotates in bottom outlet.
Description
Technical field
The present invention relates to a kind of being mainly used in dalle is fixed on crab-bolt on the building unit, especially a kind of architecture advances of crab-bolt belongs to the architectural decoration technical field of fastening.
Background technology
Crab-bolt is by the principle of expansion fastener, and main effect is that the various dalles with stone material curtain wall and so on are fixed on the building unit of metal keel and so on.
Existing crab-bolt by cone headed screw rod, be enclosed within the sleeve on the screw rod, the packing ring between screw head and sleeve, the nut that screws on screw rod constitutes.During use, screw head is inserted in the corresponding aperture on the sheet material, impingement sleeve stretches gasket deforms, and crab-bolt just tentatively is fixed on the sheet material.Then screw nut, sleeve is pressed to the first end of screw rod, thereby, packing ring is further supportted distending, whole crab-bolt and dalle are fixed together, and then can easily it be fixed on the building unit by the circular cone of screw head.
Yet the problem that existing crab-bolt exists in application is, because the sectional area of screw head is little, when crab-bolt is subjected to impact force, stress ratio is more concentrated, the phenomenon with puncture at the bottom of the dalle hole of stone material curtain wall and so on might occur, thereby completely lose fastening effect.In addition, when screwing nut, screw rod with the nut rotation, influences fastening effect easily.
Summary of the invention
Primary and foremost purpose of the present invention is: the problem that exists at above prior art by architecture advances, proposes a kind ofly can effectively to resist external impact force, avoids the high power anchor bolt of puncture at the bottom of the plate hole.
Further aim of the present invention is: a kind of high power anchor bolt that screw rod rotates in bottom outlet can avoid installing the time is provided.
In order to reach above primary and foremost purpose, high power anchor bolt of the present invention comprises cone headed screw rod, is enclosed within sleeve, the packing ring between screw head and sleeve on the screw rod, screw the nut on screw rod, its improvements are: described sleeve is shaped on external screw thread, is rotary with the pressure holding nut on the described external screw thread.
Like this, crab-bolt of the present invention not only can be fixed in the various sheet materials such as stone material, ceramic wafer, fiberboard as original crab-bolt very easily, and can after fixing the pressure holding nut be screwed, and is pressed in plate surface.When being subjected to impacting, the impact force that originally acted at the bottom of the hole is transferred to plate surface, by the pressure holding nut with larger sectional area, active force is disperseed, thereby rationally solves the problem that prior art exists, and avoids puncturing at the bottom of the hole.This structure also has and avoids to a certain extent because of when punching action effect of rotating in bottom outlet of the screw rod that causes of various factors simultaneously.
In order to reach further purpose, crab-bolt of the present invention has also been taked following architecture advances: at bush outer sleeve the plasticity cover is arranged, be preferably in the front end jag of plasticity cover.
Like this, combine, can when screwing nut fastener, effectively avoid the screw rod at center to rotate thereupon, thereby make things convenient for fitting operation, installation quality is provided by the effect of frictional force with above crab-bolt structure of the present invention.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the embodiment of the invention one.
Fig. 2 is the structural representation of the embodiment of the invention two.
The specific embodiment
Embodiment one
Present embodiment is with sleeve 1 on the cone headed screw rod 8 as shown in Figure 1, and ripple packing ring 2 is housed between the nose cone of screw rod and the sleeve.The thread segment of screw rod 8 carries fastening screw nut 5 and 7.Different with like product is that sleeve 1 is shaped on external screw thread, is rotary with pressure holding nut 4 on this external screw thread.During use, the nose cone of screw rod 8 is inserted in the corresponding aperture 3 prefabricated on the sheet material, impingement sleeve 1 or fastening screw nut 5 stretch ripple packing ring 2 compressive deformations.When sleeve 1 is pressed to the first end of screw rod, by the nose cone of screw rod 8 ripple packing ring 2 is supportted distending fully, whole crab-bolt is fixed on the sheet material, again pressure holding nut 4 is screwed, be pressed in plate surface, by pad 6 and fastening screw nut 7, dalle be fixed on the keel piece 9 at last.
The crab-bolt of present embodiment is reused by the double fixed of pressure holding nut and fastening screw nut, therefore the ripple packing ring is fully expanded, and the effect that tightens up is very reliable.Simultaneously, the diameter of pressure holding nut is bigger, is receiving when impacting, and the impact force that originally acted at the bottom of the hole can be transferred to plate surface, and active force is disperseed, thereby avoids occurring at the bottom of the plate hole improper situation such as punctures, guarantee fastening reliably.
Embodiment two
Present embodiment as shown in Figure 2, basic structure is identical with embodiment 1, difference is, the pressure holding nut is lined with the plasticity packing ring 10 that nylon is made for 4 times, the outside of sleeve 1 is with the plasticity cover 11 that nylon is made.Like this,, can make being connected of crab-bolt and sheet material tightr, reliable, when being subjected to impacting, play desirable cushioning effect, prevent that friable plate material is damaged or crack by plastic material when crab-bolt is applied on the friable plate materials such as glass, ceramic tile.Simultaneously, plastic material can avoid screw rod to rotate with nut driving, thereby helps guaranteeing the stable of workmanship.Especially, after an end of plasticity cover 11 adopted the jag structure, after tightening up, jag place abundant went out the slit that material can be full of the ripple packing ring, makes above-mentioned action effect better.
In addition to the implementation, the present invention can also have other further to improve embodiment.For example, the male threaded stub of sleeve is shaped on the reducing step, screw thread damaged in the time of can avoiding impingement sleeve like this; And for example, plastic material adopts other plastics; For another example, replace above-mentioned plasticity cover with suit plasticity cap on the screw rod nose cone; Or the like.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
