Description
Technical field
The utility model relates to the building steel frame node that is rigidly connected, particularly a kind of box beam/column with steel structure and the i beam special-shaped node of cross that is rigidly connected.
Background technology
Electric power is the emphasis basic industry of national economy, in the steam power station, adopts big capacity unit (more than the 600MW), and not only technical indicator advanced person, and environment-friendly advantage and energy conservation and consumption reduction effects are obvious, meet strategic overall situation, have wide development and application prospect.Main building is the core of thermal power plant, the general three row formula structures that comprise steam turbine building, deaerator bay and bunker bay that adopt.The big not only stressed complicacy of capacity unit main building structure, load is huge, and physical dimension and deadweight also increase with the increase of its capacity.Existing research shows; Because the deficiency of structural system itself; Low, the poor seismic behavior of conventional steel reinforced concrete main building structural entity supporting capacity, have that part bottom column sectional dimension is excessive, ratio of axial compressive force to axial compressive ultimate capacity of section transfinites and geological process under problem such as structure relative storey displacement and top displacement be bigger than normal, the structural safety deposit is lower, durability is not enough; Therefore 8 degree set up defences and more than high earthquake intensity area, the reinforced concrete structure form can not satisfy the requirement of big capacity unit main building.In order to advance thermal power plant's structural system innovation, improve the anti-seismic performance of main building structure, demand developing a kind of new structure system urgently, be applicable to the big capacity unit main building of highly seismic region.The steel work layout is flexible, and mechanization and industrialization degree are high, and anti-seismic performance is good, is the sustainable development product of environment-friendly type.Therefore, adopt steel work main building system in the thermal power plant, can overcome the shortcoming of reinforced concrete structure, satisfy high earthquake intensity ground area large-capacity unit main building rigidity and requirement for bearing capacity.
Because arts demand, the load that the main building bunker bay bears is huge, and the load that deaerator bay bears is less; In the design of steel work main building, the depth of section of beam that bunker bay adopts is more much bigger than deaerator bay, therefore; In the framework of bunker bay and deaerator bay formation; The depth of section difference and the difference of same node place post two curb girders are bigger, and joint cores has been divided into two parts up and down, form the special-shaped node of steel work.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art; The purpose of the utility model is to provide a kind of box beam/column with steel structure and the i beam special-shaped node of cross that is rigidly connected; I beam through box beam/column with steel structure is different with the both sides depth of section is rigidly connected; Form a kind of box beam/column with steel structure and the i beam special-shaped node of cross that is rigidly connected; Can either satisfy the technological requirement of big capacity unit main building, have good supporting capacity and anti-seismic performance again, steel work main building structure can be applied in highly seismic region big capacity unit main building.
In order to achieve the above object, the technical scheme of the utility model employing is:
A kind of box beam/column with steel structure and the i beam special-shaped node of cross that is rigidly connected; Comprise box column 1; The first post edge of a wing, the 11 external big i beams 2 of box column 1; The second post edge of a wing, 12 external little i beams 3, the upper flange of girder 21 of said big i beam 2 and the girder top flange 31 of little i beam 3 are at the sustained height place, and the crossbeam bottom flange 22 of big i beam 2 is lower than the girder bottom flange 32 of little i beam 3.
For guaranteeing the clear and definite and further reinforcement intensity of power transmission, in box column 1, be respectively arranged with:
With the last stiffening rib 4 of upper flange of girder 21 height such as grade and level, with the middle stiffening rib 5 of girder bottom flange 32 height such as grade and level and with the following stiffening rib 6 of crossbeam bottom flange 22 height such as grade and level; The said post edge of a wing 11 of going up stiffening rib 4, middle stiffening rib 5 and following stiffening rib 6 and box column 1; 12 usefulness electroslags welding with consumable nozzle connect; Be connected with the column web 13 usefulness groove penetration weld of box column 1, stiffening rib 5 is divided into upper and lower two parts in the core space quilt, is respectively core space and following core space.
Between box column 1 and the big i beam 2, between box column 1 and the little i beam 3, all adopt to be rigidly connected, for example full weldering connection or bolt weldering mix and connect.
Compared with prior art, the beneficial effect of the utility model is:
1) easy construction because box steel column, steel I-beam all can machine in processing factory in advance, be transported to the scene after, directly lift assigned address and connect, speed of application is fast;
2) practice thrift steel, adopt the i beam of different cross section height in the box column both sides, both can guarantee to meet the demands, can avoid waste again at the less side steel of load at the bigger side bearing capacity of load;
3) bearing capacity is high; Anti-seismic performance is good; Experimental study shows, the be rigidly connected ductility of the special-shaped node of cross of box beam/column with steel structure and i beam is similar with the rigidly connected regular node of energy dissipation capacity and steel work, core space shear-carrying capacity even be higher than regular node; Anti-seismic performance is superior to the reinforced concrete irregular node fully, makes steel work main building system in the big capacity main building of highly seismic region thermal power plant, be able to apply.
