Description
Technical field
The utility model belongs to building structure field, is related to buildings in general construction, and in particular to build in earthquake territory
Tall Concrete Buildings 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, add the replaceable company of energy-consuming parts
Beam, steel truss coupling beam, improved steel truss coupling beam.Weakening type replaceable coupling beam in section typically surrenders 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 shortcomings that steel truss coupling beam is to connect complex in truss structure, is easily sent out under moderate finite deformation
Raw junction is destroyed or the outer unstability of steel member plane；The improvement steel truss coupling beam that China Mining University proposes, remains steel pipe and mixes
The solidifying upper and lower chord member of soil, 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 are 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, it is more traditional should be regarded as sandwiched a metal damper, the energy dissipation capacity of this coupling beam between upper and lower chord member
Steel truss coupling beam improve it is 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 are inevitably enlarged to adapt to this change.
Therefore, the advantages of comprehensive existing replaceable coupling beam, develop that a kind of stress performance is excellent, energy dissipation capacity is strong, again
The coupling beam that replacing can be easy to repair after shake is significant.
Utility model content
In order to overcome weak point existing for existing replaceable coupling beam at present, it is not in flat that the utility model, which provides one kind,
Unstability outside face, because middle part vertical deformation is excessive will not be produced to floor unfavorable shadow noon, will not also increase upper and lower chord member bearing requirements
Steel truss-high spin system superimposed sheet combine replaceable coupling beam.
Technical scheme is a kind of replaceable steel truss-high spin system superimposed sheet combination used by the utility model
Coupling beam, including the upper and lower chord member of steel pipe high spin system, them web, the two panels high resistant connected by lattice Steel bar rack
The hollow cover plate of Buddhist nun's lightweight aggregate, the built-in fitting in O-shaped Q235B steel plates connector and reinforced concrete shear wall；The steel pipe high resistant
The upper and lower chord member of damping concrete and them web and the built-in fitting of reinforced concrete shear wall wall limb pass through the high-strength spiral shell of friction-type
Tether and connect；The upper and lower chord member of steel pipe high spin system passes through O-shaped with horizontal low surrender steel steel bar in them web
Q235B steel plates connector welds.
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 using the low surrender steel plate of perforate；
The hollow cover plate of high-damping lightweight aggregate is light with mono-layer level distribution bar and vertical distribution bar, two panels high-damping
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, it is welded on the low surrender steel steel bar of upper level of them web and lower level
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 welds；
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 utility model 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, the stress characteristic of each part carrying division of labor clearly, with general truss coupling beam.
(2) due in the upper and lower chord member of concrete filled steel tube using high spin system, them web using
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 horizontal low surrender steel steel bar 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
In raw unfavorable shadow noon, it is easy to repair, has a good application prospect.
