Abstract
The invention discloses a kind of novel high-strength fastener, including the body of bolt, the head of the described body of bolt is provided with therewith the mutually ailhead of integration, the afterbody of the described body of bolt is provided with the end that is screwed, bowl-shape fastening back-up ring is provided between described ailhead and the body of bolt, the surface at the described end that is screwed is provided with equally distributed screw thread.Novel high-strength fastener constructions are compact, lift security, improve performance.
Description
Technical field
Patent of the present invention belongs to fastener technical field, more particularly to a kind of novel high-strength fastener.
Background technology
The bolt used in the middle of steel construction in the prior art, commonly there is low intensity, degree of firmly installing is not high, cause the reduction of steel construction stability, in the presence of certain potential safety hazard, including bolt head, ring flange and cylindric screw rod coaxial and be cast as one, one end on the screw rod away from ring flange is provided with screw thread, the reach is less than screw rod total length, a longitudinal fluting is provided with the screw rod, a diversion canal for being connected with the longitudinal fluting and leading to flange plate edge is also set up on the end face that the ring flange is connected with screw rod.As improvement, an annular groove, longitudinal fluting and diversion canal of the annular groove connect setting on screw rod are provided with the end face that the ring flange is connected with screw rod.Performance is not relatively outstanding when this structure is used, and uses when in corresponding structure, and the intensity relative deficiency of bolt, service life is easily reduced.
Patent of invention content
Patent of the present invention provides a kind of compact conformation, and performance is outstanding, at the same it is easy to operate, increase the novel high-strength fastener of intensity.
In order to solve the above problems, patent of the present invention uses following technical scheme：A kind of novel high-strength fastener, including the body of bolt, the head of the described body of bolt is provided with therewith the mutually ailhead of integration, the afterbody of the described body of bolt is provided with the end that is screwed, bowl-shape fastening back-up ring is provided between described ailhead and the body of bolt, the surface at the described end that is screwed is provided with equally distributed screw thread.
Preferably, described being screwed between end and the body of bolt is provided with torsion and cuts breach, and left-hand end and the right-hand end at the described end that is screwed are respectively equipped with chamfering, the diameter at the described end that is screwed and the equal diameters of the body of bolt.
Preferably, described ailhead is regular hexagon, and the diameter of the described body of bolt is less than the diameter of ailhead, the described diameter with diameter greater than ailhead for fastening back-up ring.
Preferably, total length of the length at the described end that is screwed less than the body of bolt.
Patent of the present invention has the advantages that：
Compared with prior art, a kind of novel high-strength fastener of patent of the present invention, compact conformation lifts security, improves performance.
Brief description of the drawings
Fig. 1 is the structural representation of patent of the present invention.
In figure：The 1- bodies of bolt；2- ailheads；3- is screwed end；4- fastens back-up ring；5- screw threads；6- is turned round and is cut breach.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to patent of the present invention.
Embodiment
As shown in Figure 1, a kind of novel high-strength fastener, including the body of bolt 1, the head of the described body of bolt 1 is provided with therewith the mutually ailhead 2 of integration, the afterbody of the described body of bolt 1 is provided with the end 3 that is screwed, bowl-shape fastening back-up ring 4 is provided between described ailhead 2 and the body of bolt 1, the surface at the described end 3 that is screwed is provided with equally distributed screw thread 5.Described being screwed between end 3 and the body of bolt 1 is provided with torsion and cuts breach 6, and left-hand end and the right-hand end at the described end 3 that is screwed are respectively equipped with chamfering, the equal diameters of the diameter and the body of bolt 1 at the described end 3 that is screwed.
Ailhead 2 is regular hexagon, the diameter of the diameter less than ailhead 2 of the body of bolt 1, the described diameter with diameter greater than ailhead 2 for fastening back-up ring 4.
Be screwed total length of the length less than the body of bolt 1 for holding 3.
In addition to the structure described in patent of the present invention, remaining is prior art.
Using technical solutions according to the invention, or those skilled in the art is under the inspiration of inventive technique scheme, designs similar technical scheme, and reaches above-mentioned technique effect, is to fall into protection scope of the present invention.
