Description

Cover M shape buckling-restrained energy-dissipation

Technical field

The power consumption that the present invention relates to a kind of building structure is supported, and particularly relates to a kind of cover M shape buckling-restrained energy-dissipation of building construction vibration control.

Background technology

Earthquake disaster has sudden and crushing, and the safety of human life, property in serious threat.Annual failure earthquake is nearly thousand times in the world, and a violent earthquake can cause the economic loss of more than one hundred billion dollar, causes the hundreds of thousands people dead or serious wounded or disabled.China is located in the world on two most active earthquake zones, is one of the most serious country that suffers disaster from an earthquake, and the casualties that earthquake causes occupies first place in the world, and economic loss is also very huge.In the earthquake considerable damage of building with collapse, be the immediate cause that causes earthquake disaster.When earthquake occured, ground vibration caused the earthquake response of structure.Be consolidated in the building structure on ground for the basis, its reaction is along successively amplifying highly from top to bottom.Because the earthquake response (acceleration, speed or displacement) of works a part is excessive, makes the heavy damage of main body load-carrying members even collapse; Although or agent structure do not destroy, the breaking-up such as architectural coating, finishing or other non-structure accessory and cause heavy losses; Or indoor expensive instrument, damage of facilities cause serious loss or secondary disaster.For fear of the generation of above-mentioned disaster, people must control the earthquake response of structural system, and eliminate " amplifier " effect of structural system.

Structure energy-eliminating shock-absorbing technology is that some nonload bearing element (such as support, shear wall, connector etc.) of bar structure is designed to the energy dissipating rod member, or at some position of structure (interlayer space, node, connecting sewing etc.) energy dissipator is installed.When little wind or little shake, these energy dissipating rod members (or energy dissipator) and structure itself have enough lateral rigidities to satisfy instructions for use, and structure is in elastic stage; When large shake or strong wind occurring; increase along with the structure lateral deformation; energy dissipation component or energy dissipator take the lead in starting working; produce larger damping; a large amount of earthquakes that consume input structures or the wind energy that shakes; making the kinetic energy of structure or elastic potential energy homenergic change into the forms such as heat energy dissipates; the rapidly earthquake of attenuating structure or the wind reaction (displacement, speed, acceleration etc.) of shaking; make agent structure avoid occurring obvious inelastic state, protection agent structure and member exempt from destruction in macroseism or strong wind.Because the reasons such as earthquake are transferred to the external energy of building structure, be the root of structure generation vibration, so energy-dissipating device is set, increase energy consumption in structure, will reduce the vibration reaction of structure.Energy dissipation component is used for support can forms various power consumptions supports, support such as cross support, diagonal brace support, K shape etc.

At present the buckling-restrained energy-dissipation of research and development has China Patent No. 200710062637.3 to disclose a kind of name to be called " steel tube anti-flex energy dissipation support " patent of invention; China Patent No. 200810204340.0 discloses a kind of name and has been called " buckling-restrained energy-dissipation " patent of invention; China Patent No. 200910081817.5 discloses a kind of name and has been called " a kind of all-steel buckling-preventing energy-consuming brace " patent of invention; China Patent No. 200910226690.1 discloses a kind of name and has been called " compound energy-consumption supporting member of automatically recovering axis function placed in the middle " patent of invention etc.Lose constraint and anti-flexing effect yet the confined concrete of some buckling-restrained energy-dissipations is easy crushed, caused its energy dissipation capacity significantly to reduce.Therefore, manufacturing process is supported in some power consumptions, and energy-dissipating property etc. still require further improvement.

Summary of the invention

The object of the present invention is to provide a kind of cover M shape buckling-restrained energy-dissipation, adopt the effectively mode of isolation, avoid confined concrete to destroy, to improve its energy dissipation capacity.Utilize the power consumption effect of overlapping the M shape buckling-restrained energy-dissipation can reduce the earthquake response of building structure, building structure is played a very good protection.

In order to realize purpose of the present invention, the technical solution used in the present invention is:

Cover M shape buckling-restrained energy-dissipation include power consumption square steel pipe, fixed position, stiffener, ribs, connection reinforcement gusset, connection reinforcement steel plate, rice font power consumption mild steel, isolation thin-walled triangle steel pipe, in fill out confined concrete and end plate, power consumption square steel pipe and rice font power consumption mild steel form a cover M shape power consumption part, eight delta-shaped regions of cover M shape arrange respectively isolation thin-walled triangle steel pipe, fill out confined concrete in building in isolation thin-walled triangle steel pipe.At power consumption square steel pipe two ends stiffener is set, the connection reinforcement gusset is set in four bights respectively in the outside of stiffener and at the middle part on four limits the connection reinforcement steel plate is set respectively.Consume energy mild steel and connection reinforcement gusset, connection reinforcement steel plate and ribs of power consumption square steel pipe, stiffener and the font of be connected all is connected with fixed position; Fixed position and ribs are M shape.Screw is set on the fixed position, with bolts with other members such as beam, posts.Isolation thin-walled triangle steel pipe is 5 ~ 20mm with the spacing of power consumption square steel pipe and rice font power consumption mild steel.Two ends at power consumption square steel pipe and rice font power consumption mild steel arrange respectively eight leg-of-mutton end plates.
