Description
Technical field
The invention belongs to technical field of buildings, in particular to a kind of partial precast assembled steel reinforced concrete mega-frame knot
Structure.
Background technique
Steel reinforced concrete structure refers to that fashioned iron is configured in reinforced concrete member section is formed by steel-concrete combination
Structure type.Compared with reinforced concrete structure, due to configuring fashioned iron, steel reinforced concrete structure inside reinforced concrete section
With the significant advantages such as bearing capacity is high, rigidity is big, anti-seismic performance is good；It is mixed due to being enclosed with outside fashioned iron compared with steel construction
Solidifying soil, steel reinforced concrete have outstanding advantages of low cost, rigidity are big, fire resistance and endurance quality are good.Therefore, fashioned iron coagulation
Soil structure is with both concrete structure and steel construction advantage.But steel reinforced concrete structure construction is generally required and is first installed
Internal type steel skeleton, then bind external framework of steel reinforcement, then formwork supporting plate, casting concrete, with steel construction and concrete structure phase
, long construction period more than, on-site construction processes and construction cost is high, for establishing resource economizing type and friendly environment society
Positive impetus is not played.
On steel reinforced concrete structure and prefabricated assembled concrete structure, propose that fully-prefabricated assembled fashioned iron is mixed both at home and abroad
Xtah Crude Clay structure form, i.e., to Steel Reinforce Concrete Members, all progress is prefabricated, then transports to building site and carries out scene splicing dress
Match, to reduce on-site construction processes and duration.Fully-prefabricated assembled steel reinforced concrete structure does not have to live assembling reinforcement, formwork
The processes such as version, pouring concrete and form removal can greatly reduce on-site construction processes and duration, accelerate site operation progress.But
It is it will be noted that full-prefabricated assembled concrete structure also has many deficiencies.First, since steel reinforced concrete structure is main
Applied to skyscraper and large span architecture, Steel Reinforced Concrete Members sectional dimension is often bigger, and member dead weight is heavier, complete prefabricated
The transport of assembled Steel Reinforced Concrete Members and lift that and hoisting difficulty more demanding to equipment tonnage be big, installation cost is high.The
Two, the concrete section in full-prefabricated assembled concrete structure in addition to reinforcing bar, fashioned iron need connection very well, between prefabricated components
Connection is also critically important, and section connection force-transmission mechanism is complex, quality of connection is not easy to guarantee.
