Description
Technical field
The invention belongs to technical field of civil engineering, it is related to a kind of energy-consuming shock absorber and work progress, it is especially a kind of
Utilize the coupling beam damper for overlapping the power consumption of truncated cone-shaped mild steel lead assembly.
Background technology
Coupling beam is critically important component in shear wall structure, in earthquake, and coupling beam is prevented as first of shear wall structure
Line should be surrendered prior to wall limb and mitigate the destruction of wall limb by being plastically deformed dissipative part seismic energy.But in Practical Project
Middle reinforced concrete coupling beamses simultaneously do not have preferable ductility and energy dissipation capacity, and new steel coupling beam or composite coupling beams are after shake
Repair or change and be relatively difficult.Therefore, scholars are studied coupling beam, some dampers for being applied to coupling beam are have developed.
So damper can first be surrendered as the first line of defence, dissipative part seismic energy, and coupling beam can be with as second defence line
Further mitigate and be easy to repair or change after the destruction of wall limb, and damper destruction.
Existing coupling beam damper generally uses mild steel, is surrendered and consumed energy using its detrusion.But according to the stress of coupling beam
Feature understands that damper is also subjected to axle power and moment of flexure while shearing is born, and the moment of flexure that two ends are subject to is big, what centre was subject to
Moment of flexure is small.Therefore existing damper can not make full use of material, the performance of damper is played.Such as：Publication No.
A kind of coupling beam damper is disclosed in CN205776860U patent, it consumes part seismic energy using the deformation of Wasted-energy steel plate
Amount, but material can not be made full use of according to the loading characteristic of coupling beam, play the performance of damper.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of mild steel lead combined type coupling beam damper, and the damper is used
The mode that truncated cone-shaped mild steel cylinder and lead for retractable pencil are combined is overlapped, the loading characteristic preferably catered in the middle part of coupling beam can give full play to
The performance of the damper, with stronger energy dissipation capacity, and simple structure, easy construction.
The technical solution adopted for the present invention to solve the technical problems is：
Mild steel lead combined type coupling beam damper, including mild steel cylinder, perfusion lead for retractable pencil, left junction steel plate and right junction steel plate.It is left
Junction steel plate and right junction steel plate are respectively welded in the left and right ends of mild steel cylinder, and lead for retractable pencil is formed by fill orifice perfusion.Its feature
It is：The mild steel cylinder uses overlapping truncated cone-shaped, and it is in the middle part of truncated cone-shaped, and mild steel cylinder that left-half is full symmetric with right half part
Diameter is less than end diameter.
It is truncated cone-shaped that the left-half of the perfusion lead for retractable pencil is full symmetric with right half part, and perfusion lead for retractable pencil is full of whole mild steel
Tube inner chamber fits like a glove with mild steel cylinder.
The left connection steel is rectangle or circle, and surrounding opens up left junction steel plate bolt hole, and centre opens up fill orifice；It is described
Right junction steel plate is rectangle or circle, and surrounding opens up right junction steel plate bolt hole.
The work progress of the mild steel lead combined type coupling beam damper：
1. left connection and right connection board are respectively welded in mild steel cylinder left and right ends；
2. lead is filled into by damper inner chamber by fill orifice and forms perfusion lead for retractable pencil；
3. gap installs mild steel lead combined type coupling beam damper in the middle part of coupling beam, left junction steel plate by high-strength bolt and
The built-in fitting connection of coupling beam left-half, right junction steel plate is connected by the built-in fitting of high-strength bolt and coupling beam right half part.
The beneficial effects of the invention are as follows：1. mild steel lead combined type coupling beam damper is using overlapping truncated cone-shaped mild steel cylinder and lead for retractable pencil
The mode of combination, left-half and right half part are full symmetric truncated cone-shaped, the loading characteristic preferably catered in the middle part of coupling beam,
Both can with shear energy dissipation can also tension and compression consume energy, stock utilization is high, with very strong energy dissipation capacity；2. mild steel lead combined type connects
Beam damper is by the way of mild steel and lead combination, and both have preferable harmony, give full play to the performance of the damper；③
Mild steel lead combined type coupling beam damper and engineering structure are connected by screw bolts, easy construction, it is easy to maintenance and replacing.
