Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is further described.
As depicted in figs. 1 and 2, a kind of novel energy-consumption shock-absorbing buckling restrained brace is provided, comprise the core board 1 adopting A5083 aluminium alloys made, be set in parallel in the upper constraint dihedral plate 2 of core board about 1 both sides and lower constraint dihedral plate 3, half cross corner plate is respectively arranged with at the two ends, left and right of upper constraint dihedral plate 2, this half cross corner plate is bolted by two pieces of L shape corner plates 41, in like manner, half cross corner plate is respectively arranged with at the two ends, left and right of lower constraint dihedral plate 3, this half cross corner plate is also be bolted by two pieces of L shape corner plates 41, the half cross corner plate at upper constraint dihedral plate 2 two ends is connected by the half cross corner plate of bolt with lower constraint dihedral plate 3 two ends, the both ends of core board 1 are carried out the fixing of upper-lower position, and make these both ends form a cross shape structure 4 (see Fig. 2), can be connected flexibly so that whole constraint supports with external equipment mechanism, lithium base grease is filled with in the upper and lower surface of core board 1, can make, between itself and upper constraint dihedral plate 2, lower constraint dihedral plate 3, there is good lubricant effect, reduce frictional force, wherein, upper constraint dihedral plate 2 and lower constraint dihedral plate 3 are all adopt A6061 aluminium alloys made.
As shown in Figures 1 to 6, core board 1 is bolted in the middle of it (see Fig. 5 and Fig. 6) by upper constraint dihedral plate 2 and lower constraint dihedral plate 3; There is large displacement of floating in order to prevent core board 1 being subject to that outside is drawn, under pressure effect to move, the both sides of core board 1 are provided with spacing snap fit 5, on upper constraint dihedral plate 2, corresponding position has upper limit draw-in groove 61, on lower constraint gusset 3, corresponding position has lower limit draw-in groove 62 (see Fig. 1), and upper limit draw-in groove 61 coordinates with lower limit draw-in groove 62 and forms spacing draw-in groove 6 and wrapped up within it (see Fig. 3) by spacing snap fit 5.
