Efficient anti-fatigue friction type high-strength screw rod double-shear connection is adopted as node splicing, so that the structural efficiency of connection is further increased.
Description
Technical field
The invention belongs to framework type wind power generation stepped and other have the steel pipe truss link technique field of fatigue loading, be specifically related to a kind of steel pipe column embossed steel plates friction-type high-strength bolt double shear connecting method.
Background technology
With the multiplex high-strength common bolt of splicing that opening shaped steel (as angle steel) is material in current space truss.This is unfavorable for antifatigue load (as blower fan pylon, bridge truss, crane truss etc.).If change frictional high-strength bolts into, anti-fatigue performance is good, but opening section stress characteristic is poor, as wind-engaging is large, and poor stability.If make the rod member of truss of steel pipe, cross section performance good (wind-engaging is little, good stability).But the rod member of general truss formula wind tower, by Flange joint, welds more, more complicated, especially unfavorable for resisting fatigue load.Flange tension bolt also easily loosens under fatigue effect.So, the connected mode of the main rod member of a kind of steel truss be found.Make it rod member stress performance good, node is simple again, welding, antifatigue.This is the major issue in the design of framework type wind tower antifatigue steel truss structure.
Summary of the invention
The object of the invention is for the deficiency in current art, there is provided one and component to be steel pipes, the radius of gyration is large, good stability, node is spliced into a kind of steel pipe column embossed steel plates friction-type high-strength bolt double shear connecting method that efficient antifatigue friction-type high-strength bolt double shear connects
The technical solution adopted in the present invention is:
A kind of steel pipe column embossed steel plates friction-type high-strength bolt double shear connecting method, comprise upper segment column, hypomere post, outer scab, friction-type high-strength bolt, interior scab, inner nut, it is characterized in that described upper segment column and hypomere post are square steel pipe, the inner surface embossing of scab outside, friction-type high-strength bolt is double threaded screw, in the embossing of interior scab external surface, gluing in hypomere post, inner nut is bonded in the inner side of interior spelling rotary corner plate in advance, and the edge bending of interior spelling rotary corner plate increases its bending rigidity.
Described upper segment column and hypomere post rely on outer scab to be connected with interior scab, and friction-type high-strength bolt is simultaneously through outer scab, upper segment column and interior scab or outer scab, hypomere post and interior scab.
Upper segment column of the present invention and hypomere post are square steel pipe, can be also round steel pipe according to technological requirement.
Further illustrate operating principle of the present invention and construction sequence:
1, in factory by gluing for interior scab in hypomere post, by gluing for inner nut in interior scab,
2, first hypomere post is installed on-site,
3, again upper segment column is installed in building site, hypomere post is inserted in upper segment column 1,
4, screw with fixing inner nut with screw rod perforation, reach prescribed depth,
5, in outside, nutting, to high-strength bolt Shi Hanzhang.
The present invention contrasts existing opening shaped steel or Flange joint steel pipe truss wind tower, and usefulness is:
The subject matter that the present invention can solve: namely component is steel pipe (square steel pipe, round steel pipe), the radius of gyration is large, good stability; Shape Coefficient is less than angle steel, and under identical front face area, by wind is less; Node is spliced into efficient antifatigue friction-type high-strength bolt double shear and connects; And scab adopts embossed steel plates, improve friction factor.The further structure efficiency improving connection.And component is steel pipe, the radius of gyration is large, better than the truss stability of opening shaped steel.The steel pipe build coefficient ratio non-close cross section closed is little, and under identical front face area, by wind is less.Node is spliced into efficient antifatigue friction-type high-strength bolt double shear and connects.
