Description
Technical field
The utility model relates to a kind of building vibration proof (or vibrations) device, is specifically related to the tensile device of architectural vibration-insulation layer.
Background technology
Seismic isolation technology has important effect to the destruction that alleviates earthquake and bring to building structure; Laminated rubber damping bearing is the earthquake isolating equipment of widespread usage in the seismic isolation technology; It has good horizontal deformability and power consumption effect; Also have simultaneously compressional stiffness preferably, therefore be applied to deaden effectively in the architectural vibration-insulation layer destruction of the horizontal vibration of earthquake, also building is played a supportive role simultaneously building.But its resistance to tension is relatively poor; Relevant specification according to China; Laminated rubber damping bearing can only be allowed the tensile stress of bearing 1MPa at most, yet for highrise building, the particularly bigger building structure of depth-width ratio; The tensile stress that produces at the laminated rubber bases place during earthquake occurrence is much larger than above-mentioned tensile stress of allowing, this has limited the application of laminated rubber damping bearing in such building structure.
In order to solve the problems of the technologies described above; Publication number is to disclose a kind of " tensile device for shock insulation layer " in 101545288 the application for a patent for invention; It is made up of a plurality of tensile structures; Wherein each tensile structure is formed by connecting through universal joint with another lanar four rod mechanism that is arranged at shock insulation layer substructure a lanar four rod mechanism that is arranged at shock insulation layer superstructure, and the plane at these two lanar four rod mechanism places is vertical each other.This tensile device has played the effect of tension in the shock insulation layer; The horizontal motion that does not simultaneously hinder laminated rubber damping bearing; But there is not buffer between each connector of this tensile device; When earthquake generation and generation vertical motion, the instant impact that receives between each member is big, influences the application life of whole device; In addition, the connection rod member dimension precision requirement in this tensile device is high, needs special producer to make.
Application number is to disclose a kind of " laminated rubber damping bearing tensile structure " in 200910226649.4 the application for a patent for invention file, and it builds up rubber earthquake isolation support and counter-force laminated rubber damping bearing group constitutes by common; Wherein, counter-force laminated rubber damping bearing group is made up of the rubber earthquake isolation support that builds up that the last counter-force arm of force that is arranged at shock insulation layer superstructure and shock insulation layer substructure respectively, the following counter-force arm of force and are located between these two counter-force arm of forces.When earthquake produces vertical motion; The last counter-force arm of force and the following counter-force arm of force produce axial squeezing action to the laminated rubber damping bearing between them; Because laminated rubber bases has compressional stiffness preferably, so this tensile structure has improved the extensional rigidity of shock insulation layer greatly.But it also exists the shortcoming of following aspect: 1, the described upper and lower counter-force arm of force is equivalent to semi girder; The vertical rigidity that it provided is limited; Laminated rubber damping bearing between them then has bigger vertical compression rigidity; Therefore the vertical load that produces when earthquake is greatly the time, and the upper and lower counter-force arm of force can produce bigger vertical deformation, thereby causes described normal stack rubber earthquake isolation support still to have the risk of destroying because of tensile stress is excessive; 2, owing to increased counter-force laminated rubber damping bearing group, therefore increase the horizontal rigidity of shock insulation layer, weakened isolating affection; 3, the counter-force laminated rubber damping bearing group manufacturing cost that is increased is high, and the production time is long.
Summary of the invention
