Description
Technical field
The present invention relates to a kind of energy dissipator, particularly relate to a kind of twin spans degree energy dissipating metal plate parallel action power design of having, and can improve the three-hole type energy absorber of damping capaicty.
Background technology
The installing energy dissipator absorbs seismic forces in building, suffer damage to reduce structure itself, and be the basic conception of production academics to shock-damping structure, nearly ten have developed the method that multiple this notion of realization over several years, and its effect is different.No. the 165491st, TaiWan, China patent announcement " earthquake energy dissipator " for example, announce No. 227281 " being subjected to scissors shock-damping energy-dissipating device ", and No. 234444 " pressure-bearing type shock-damping energy-dissipating device " patent case of bulletin, all be as shown in Figure 1 haply, it is the structural upright schematic diagram of the general existing energy dissipator of an explanation, it is the trapezoidal energy dissipating metal plate 1 that adopts a kind of hinged end 11 narrow than fixed end 12, and make energy dissipating metal plate 1 metal plate face direction and be subjected to force direction vertical, because when last, following metal metal plate 13,14 when relative displacement takes place on being subjected to force direction, it is bigger that fixed end 12 produces moment of flexure, therefore borrow the trapezoidal design of energy dissipating metal plate 1, can bear seismic forces comparatively fifty-fifty and produce distortion, with the vibration limits power of payment earthquake.
In addition, the TaiWan, China patent announcement still there be No. 482851 " antishock device and construction method thereof " with replaceability, a kind of X-shaped energy dissipating metal plate 10 of easy replacement as shown in Figure 2 more is provided, see also shown in Figure 2, it is the schematic diagram that the another kind of general existing antishock device of an explanation is implemented on the situation between pillar, its metal plate face equally vertically is subjected to force direction, when last, between the works of following connection when being subjected to force direction to produce relative displacement, this X-shaped energy dissipating metal plate 10 is last, following fixed end moment maximum, area is also maximum, therefore can make the deflection plastic strain fifty-fifty of each section, earthquake energy can reduce the suffered seismic forces of building whereby.The energy dissipating metal plate 10 of deflection deformation can be fitted up wallboard by taking apart afterwards, unclamp bolt 101, and energy dissipating metal plate 10 mating components such as grade are changed.
Yet, the hinged end 11 of the former energy dissipator is made complicated, and energy dissipating metal plate 10 lower ends of fixed end 12 and latter's antishock device are to adopt welding fixing, and have the problem that welding heat influences physical characteristic, what is more important is because the energy dissipating metal plate is vertical with active force (suffered seismic forces), when construction is embedded in wall or the post, wall thickness degree or post width need cooperate metal plate material size to increase, and influence the interior space.In addition, when the energy dissipating metal plate is stressed, be subjected to the degree of plastic strain on the force direction to be subjected to the restriction of its single span degree design and height between hinged end and fixed end, so the ability of shock-absorbing energy dissipating is also therefore limited.
This shows that above-mentioned existing energy dissipator obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of three-hole type energy absorber of new structure, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because the defective that above-mentioned existing energy dissipator exists, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of three-hole type energy absorber of new structure, can improve general existing energy dissipator, make it have more practicality.Through constantly research, design, and, create the present invention who has practical value finally through after studying sample and improvement repeatedly.
