Description
Technical field
The present invention relates to construction engineering technical field, it is more particularly to a kind of combined using steel core concrete column and girder steel it is pre-
Assembling frame processed.
Background technology
Greatly develop assembled architecture and have become national strategy, prefabricated assembled concrete structure (PC structures) obtains fast
Exhibition is hailed, frame structure is one of structure type of most common of which, there is relatively broad application in prefabricated construction.
Existing PC frame structures are that concrete column, beams of concrete are prefabricated in the factory, the live wet construction method by being poured after entirety
Assembly connection is carried out, is had the shortcomings that：1. construction material, based on armored concrete, the strength of materials is relatively low, section is big, weight
Greatly, inconvenience is brought to prefabricated, transport, lifting and assembling；2. reinforcing bar is numerous at assembled in situ, connecting structure is complicated, construction
Quality is difficult to be protected；3. being connected using wet method, in addition to program is cumbersome, also it is unfavorable for reducing airborne dust, reduces pollution；4. use
After the assembly method poured after monoblock type is, it is necessary to wait the concrete of cast in situs to reach some strength, next process can be carried out
Construction, the technology intermission time length, be unfavorable for improve efficiency.
Concrete filled steel tube is the fill concrete in steel pipe, bears the structural elements of external load effect jointly, uses frame
During column, the advantages of concrete and steel can be given full play to, hence it is evident that improve the bearing capacity of component, increase the ductility and shock resistance of structure
Energy.Steel strength is high, deformability is strong, isotropism, when I-shaped or box-shaped is made in section, is well suited for being used for beam etc. to undertake
Component based on moment of flexure.
Concrete filled steel tube and girder steel are combined, sectional dimension can be reduced, mitigates construction weight, it is real for increase building
Area is obtained, reduces floor height, reducing transport and installation cost has positive effect.Meanwhile high-strength bolt and weldering are used between component
The dry method connection such as connect in succession, easy to control the quality, efficiency improves.Good comprehensive benefit can be obtained.
