Description
Technical field
The utility model relates to building structure aseismatic and to set up defences field, particularly a kind of mild steel damper.
Technical background
Mild steel damper comes catabiotic by the plastic strain of metal material, the mild steel damper be installed in building structure can be provided in certain rigidity for building structure, and the energy of the extraneous input that can dissipate when building construction vibration, therefore mild steel damper is widely used in the antidetonation vibration damping field of building structure.
The energy dissipating portion of current mild steel damper both domestic and external mainly adopts plank frame, and by cutting difform hole or reinforcement is distinguished or meets various parameter request on steel plate, small part is also had to adopt annular, the energy dissipating portion of taper shape or double cone shape, no matter which kind of shape energy dissipating portion adopts, it is all adopt the mode of welding to be connected on lower connecting plate, due to permanent set and residual stress can be produced at weld, be difficult to the quality ensureing damper, under partial picture, weld even there will be cracking or phenomenon of rupture, cause the inefficacy of damper, lose antihunt action, in addition also owing to adopting welding manner to connect energy dissipating portion and upper lower connecting plate, damper cannot reclaim use, causes certain waste.
Existing mild steel damper can only consume energy in a direction, but the seismic wave conduction orientation of earthquake has uncertainty, therefore for effectively reducing the infringement that earthquake brings building, at present adopt installs damper in the X-direction of building structure and Y-direction more simultaneously, but still effectively can not consume the energy that any direction that earthquake brings inputs, damping effect is reduced, well cannot ensure the safety of building structure.
At present, in order to make mild steel damper adapt to different buildings, need to carry out the corresponding damper of independent Design and manufacture according to the requirement of building, work consuming is consuming time, increases building costs.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, a kind of cylindrical steel rod type mild steel damper is provided, this mild steel damper can overcome because energy dissipating portion and the employing of upper lower connecting plate are welded to connect effectively, the quality problems occurred in weld generation permanent set and residual stress.
Meanwhile, the utility model can also consume the energy that any direction that earthquake brings inputs effectively, solves because mild steel damper can only a direction power consumption, effectively cannot consume the problem of the energy that any direction that earthquake brings inputs.
The utility model also has strong adaptability, saves Design and manufacture cost, thus reduces the effect of building costs.
The utility model adopts following technical scheme:
A kind of mild steel damper, comprise power consumption rod, upper junction plate and lower connecting plate, it also comprises bolt, and upper junction plate with lower connecting plate are provided with the connecting hole for being connected power consumption rod, and power consumption rod is connected between upper junction plate and lower connecting plate by connecting hole by bolt.
Owing to have employed bolt connecting mode, avoid the permanent set and residual stress that produce at weld due to welding, therefore no longer occur owing to welding the quality problems that cause; Simultaneously owing to have employed bolt connecting mode, for a certain reason and after mild steel damper is disassembled, upper junction plate wherein and lower connecting plate can be recycled, reduce the manufacturing cost of damping sheet, also indirectly reduce the manufacturing cost of building.
Further, described power consumption rod comprises surrender section and is arranged on the linkage section at surrender section two ends, surrender section and linkage section are cylindrical, the diameter of surrender section is less than the diameter of linkage section, transition circle frustum is provided with between surrender section and linkage section, the large end of transition circle frustum is connected with linkage section, and the small end of transition circle frustum is connected with surrender section.Further, transition circle frustum is all curved with the junction of surrender section and linkage section.
Or, power consumption rod comprises the thick column in narrow kidney-shaped in middle thin two ends and is connected to the upper connecting cylinder of top and bottom of column and lower connecting cylinder, the diameter of upper connecting cylinder is identical with the diameter of the upper surface of column, and the lower diameter of connecting cylinder is identical with the diameter of the lower surface of column.
Owing to have employed the power consumption rod of cylindrical or narrow kidney-shaped, make mild steel damper can be consumed the seismic energy that different directions inputs by the distortion of going up in any direction, and rigidity and damping are provided in different directions, there is superior performance, effectively can solve traditional mild steel damper can only the power consumption of direction, effectively cannot consume the problem of the energy that any direction that earthquake brings inputs.Especially the power consumption of narrow kidney-shaped rod is adopted to have more superior performance, because the cross-sectional area of the middle part of this power consumption rod is minimum, along with the increase of external load, the position that mild steel damper enters plastic strain is expanded to two ends, and therefore this mild steel damper has higher energy efficiency.
For making the easy for installation of mild steel damper, connecting hole on upper junction plate and lower connecting plate is set to counterbore, enable the bolt head of bolt be submerged in inside on upper junction plate and lower connecting plate completely, eliminate because bolt head stretches out the end face of upper junction plate and lower connecting plate and cause the installation inconvenience of mild steel damper.
Further, power consumption rod is at least two, and consume energy excellent regularly arranged formation array.Power consumption rod is designed to the standard component of same size, according to the power consumption rod of different engine request choice arrangement varying numbers, owing to consuming energy, rod becomes standard component, reduces the cost manufacturing power consumption rod, while decreasing the manufacturing cost of mild steel damper, decrease the manufacturing cost of building.
