Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of weathering steel bolts, are simple to manufacture, at low cost, resistance to
Corrosion, rigidity are strong.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme: a kind of weathering steel bolt, including
Shank of bolt main body and metal external member, the metal external member are sheathed on shank of bolt main body upper end, and the shank of bolt main body includes bolt
Upper boom and bolt lower beam, the bolt upper boom are fixedly connected above bolt lower beam, and the bolt upper boom is a cylindrical body, institute
State bolt upper boom diameter D be 5mm, the bolt lower beam be section be one it is trapezoidal tip upside down on another it is trapezoidal on cylindrical body
Component, two trapezoidal tops are overlapped, and the angle α that described two trapezoidal side edges are formed is 160 °, on the bolt lower beam
Equipped with screw thread, the screw thread is trapezoidal thread, and the trapezoidal thread is that the side of form of thread is trapezoidal screw thread, the screw thread
The distance between L be 0.5mm, the angle β on the form of thread between adjacent two tooth is 50 °, and the form of thread height H is
0.8mm, the metal external member include metal handle, ferrule and metallic sheath shell, and the metal handle is welded to connect in metal
On head center line, the ferrule lower end and metallic sheath shell upper end are welded to connect, and the ferrule is a cylindrical body, described
Cylinder diameter R is 9mm, and the metal grease head highness B is 5.5mm, and the metallic sheath shell is a hollow cylinder, the gold
Category set of shells diameter F is 8mm, and the wall thickness P of the metallic sheath shell is 1.5mm, and the metallic sheath body height C is 3mm.

95°。
The bolt upper boom height G is 4mm, and the bolt upper boom and metallic sheath shell are interference fitted.
The shank of bolt main body uses weather-proof steel construction.
Beneficial effect
A kind of weathering steel bolt of the utility model, including shank of bolt main body and metal external member, structure is simple, cost of manufacture
Low, the shank of bolt main body uses weather-proof steel construction, and weather-proof steel construction is added to appropriate element Cu on the basis of conventional steel,
Generation refinement crystal grain is reacted with other elements, is improved the corrosion resistance of material, is improved the low-temperature flexibility and fracture toughness of material,
Harden ability can be improved, and be conducive to improve the corrosion resistance and elevated temperature strength of material；Non- gold contained in steel is reduced significantly
Belong to the amount of inclusions, reduce the delayed fracture sensibility of material, improve the intensity and toughness of material, so that entire bolt is strong
Degree becomes larger, and rigidity becomes strong.
