Operating principle:
Anti-buckling when being supported on tension and pressing axial force, under the constraint element effect forming at forward and backward T-steel plate and intermediate plate, when being subject to tension and compression, core can reach surrender completely, and pressurized is flexing not, thereby gives full play to the hysteretic energy effect of steel.
Because weld with the two ends diagonally opposing corner of core respectively at the two ends of power transmission steel pipe, when core tension, the welding end of two groups of power transmission steel pipes is along with move in opposite directions to both sides together core end, when mobile certain displacement, contact with the left and right end plate of being furnished with reset muscle and pushing tow end plate, reset muscle tension, because reset muscle is the material of high-yield strength, unyielding during tension, keep elastic range, after removing external force, reset muscle relies on the elastic deformability of self to drive core return; When core pressurized, power transmission steel pipe is along with the contraction of core, the welding end of two groups of power transmission steel pipes is along with move in opposite directions to both sides together core end, during mobile certain displacement power transmission steel pipe not welding ends contact with the left and right end plate of being furnished with reset muscle and pushing tow end plate, reset muscle tension also remains in elastic range, after removing external force, reset muscle relies on the elastic deformability of self to drive core return, thereby realizes the function of anti-buckling support tension pressurized Self-resetting.
In the middle of core stage casing, establishing projection object is, when curvature-prevention support component and building beam column structure have certain angle to arrange, before and after preventing, T-shaped plate and intermediate plate, because of deadweight slippage, cause the constrained of T-shaped plate before and after changing, and affect the performance of anti-buckling support.
