Description
Technical field
The invention belongs to building structure field, it is related to buildings in general construction, and in particular to the coagulation built in earthquake territory
Native high building structure, more particularly to a kind of enhanced replaceable coupling beam of power consumption that can be practical.
Background technology
Current replaceable coupling beam has four types, i.e.,：The replaceable coupling beam of section weakening type, the additional replaceable company of energy-consuming parts
Beam, steel truss coupling beam, improved steel truss coupling beam.Weakening type replaceable coupling beam in section is general to surrender steel plate based on low,
Easily there is the outer unstability of plane in steel plate under moderate finite deformation after its weakening；Largely deformation all collects the additional replaceable coupling beam of energy-consuming parts
In span centre position dissipative member, the floor that its excessive vertical deformation may be damaged above coupling beam, this certainly will limit it
Application in Practical Project；The shortcoming of steel truss coupling beam is to connect complex in truss structure, is easily sent out under moderate finite deformation
Raw junction destruction or the outer unstability of steel member plane；The improvement steel truss coupling beam that China Mining University proposes, remains steel pipe and mixes
Native upper and lower chord member is coagulated, web member is changed to low surrender steel web, steel web is constrained outside its plane by two pieces of reinforced concrete cover plates
Deformation, steel web is not in contact with only being connected with chord member by otic placode with shear wall wall body；Improved steel truss coupling beam is actually not
It is a truss structure, should be regarded as a sandwiched metal damper between upper and lower chord member, the energy dissipation capacity of this coupling beam is more traditional
Steel truss coupling beam improves many, but upper and lower chord member must undertake the moment of flexure in section, shearing, axle power effect completely, add,
The bearing requirements of lower boom, namely the section of upper and lower chord member inevitably enlarge to adapt to this change.
Therefore, the advantage of comprehensive existing replaceable coupling beam, a kind of stress performance of development is excellent, energy dissipation capacity is strong, again
The coupling beam that replacing can be easy to repair after shake is significant.
The content of the invention
In order to overcome the weak point that existing replaceable coupling beam is present at present, it is not in outside plane that the present invention, which provides one kind,
Unstability, unfavorable shadow noon will not be produced to floor because middle part vertical deformation is excessive, will not also increase the steel of upper and lower chord member bearing requirements
Truss-high spin system superimposed sheet combines replaceable coupling beam.
The technical solution adopted in the present invention is that a kind of replaceable steel truss-high spin system superimposed sheet combination connects
Beam, including the upper and lower chord member of steel pipe high spin system, them web, the two panels high-damping connected by lattice Steel bar rack
Built-in fitting in the hollow cover plate of lightweight aggregate, O-shaped Q235B steel plates connector and reinforced concrete shear wall；The steel pipe high-damping
The upper and lower chord member of concrete and them web and the built-in fitting of reinforced concrete shear wall wall limb pass through frictional high-strength bolts
Connection；The upper and lower chord member of steel pipe high spin system passes through O-shaped with the low surrender steel steel bar of level in them web
Q235B steel plates connector is welded.
The steel pipe high spin system top boom and steel pipe high spin system lower boom, its inner side welding U-type groove steel；
The them web, it is low in the wrong by the low surrender steel steel bar of upper level, the low surrender steel steel bar of lower level and X-type
Steel steel bar composition is taken, or uses the low surrender steel plate of perforate；
The hollow cover plate of high-damping lightweight aggregate is with mono-layer level distribution bar and vertical distribution bar, and two panels high-damping is light
The hollow cover plate of aggregate is by lattice bar connecting；
The them web is placed in the hollow cover plate of two panels high-damping lightweight aggregate of lattice Steel bar rack connection, surface
It is coated with non-cohesive material；
The O-shaped Q235B steel plates connector, is welded on the low surrender steel steel bar of upper level and lower level of them web
On the outside of low surrender steel steel bar, and with steel pipe high spin system top boom with it is U-shaped on the inside of steel pipe high spin system lower boom
Channel-section steel is welded；
The steel pipe high spin system top boom and steel pipe high spin system lower boom and them web, with steel
The built-in fitting of reinforced concrete shear wall wall limb passes through high-strength friction bolt connection.
The present invention has following remarkable advantage:
(1) this replaceable coupling beam is undertaken the effect of section turn moment and axle power by top-bottom chord, and top-bottom chord is total to web
With the effect for undertaking section shear, each part carrying division of labor is clear and definite, the stress characteristic with general truss coupling beam.
(2) due to using high spin system in the upper and lower chord member of concrete filled steel tube, them web is used
Low surrender steel, constraint them web is the hollow cover plate of two panels high-damping lightweight aggregate connected by lattice Steel bar rack, under
Chord member with the low surrender steel steel bar of level in them web is connected by O-shaped Q235B steel plates connector, and its energy dissipation capacity shows
So increased substantially compared with general truss coupling beam.
(3) this replaceable coupling beam is not in the outer unstability of plane, floor will not also be produced because middle part vertical deformation is excessive
Raw unfavorable shadow noon, it is easy to repair, have a good application prospect.
