Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model The scope of protection.
A kind of rubber-type friction energy dissipation amortisseur as depicted in figs. 1 and 2, including friction steel plate 2 be fixed on Positioning baffle 7 between grip block 1 up and down, friction steel plate 2 is along positioning baffle 7 linear slide;Friction steel plate It is provided with rub resistance rubber slab 3 between 2 and upper and lower grip block 1;Friction steel plate 2 is provided with bolt connecting hole 4; Grip block 1 is threadeded with precompressed bolt hole 5 thereon by precompressed bolt 8 up and down.The rub resistance that 4mm is thick Rubber slab 3 one side is pasted onto on the contact surface of upper and lower grip block 1, and friction rubber plate 3 also wraps up along sliding side Edge before and after grip block up and down 1 upwards, so can increase friction further, improves stability.Or 4mm rub resistance rubber slab 3 it is stained with on the two sides of friction steel plate 2.Positioning baffle 7 has two panels, this positioning baffle 7 are fixed in the left and right both ends of the surface between upper and lower grip block 1 by hex bolts 6;Positioning baffle 7 top with Gap is left up and down between grip block 1.Grip block 1 length 200~500mm up and down, width 200~300mm, Thickness 10~30mm;Friction steel plate 2 a length of 350~600mm, width 150~250mm, thickness 10~ 30mm.The thickness of rub resistance rubber slab 3 is 3~10mm, and tundish is wrapped with one layer can reduce sheet rubber pressurized The frame board of deformation, reduces long-time use sheet rubber strength retrogression.The thickness of frame board is 2~3mm.Rub Wiping steel plate 2 one end is bolted hole 4 and is connected with structure built-in fitting, and the other end passes through welding manner and knot Structure built-in fitting connects, and reduces the required precision installed, and is conducive to installing.Precompressed bolt 8 use 8.8 grades or 10.9 grade high-strength bolts, it is real that quantity produces pretension by calculating torque spanner in high-strength bolt Existing required precompression.Two sides clamping steel plate 1 is fixed with 4 M30 10.9 grade high-strength bolts, sets precompressed Power is 50T, tightens each bolt with torque spanner, and adds spring pad bolt, each bolt precompression 12.5T. The positioning baffle 7 of both sides six hex bolts 6 are fixed.
Work process of the present utility model is: screw in the precompressed spiral shell on upper and lower grip block 1 by precompressed bolt 8 In keyhole, the precompression of generation makes friction steel plate 2 and rub resistance rubber slab 3 compress and has produced sliding damping force. Play sliding damping force size to be controlled by precompression regulation, i.e. produced in precompressed bolt 8 in advance by torque spanner Pulling force realizes required precompression.Intermediate friction steel plate 2 not sideslip unstability is made by two panels positioning baffle 7, Positioning baffle 7 top and upper and lower grip block 1 leave gap so that it is do not affect friction displacement, improve power consumption energy Power and sinker stability.Building is when by load or chance small earthquake, and its shearing force has been less than sliding resistance During Buddhist nun's power, between friction steel plate 2 and rub resistance rubber slab 3, do not produce relative displacement, can come at precompression Control horizontal rigidity.When big shake effect, friction steel plate 2, rub resistance rubber slab 3 produce after overcoming damping force Relative displacement, displacement capacity is very big, on the one hand the ability of Seismic input is dissipated, on the other hand makes building Horizontal rigidity diminishes, and the hysteresis loop of its power consumption is full, and energy dissipation capacity is relatively big, and Performance comparision is stable, it is to avoid Deformation that during big shake, building is big and destroy.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
