Description
Technical field
The present invention relates to a kind of prefabricated assembled concrete frame joint component and its preparation construction methods, belong to building work
Journey technical field of buildings.
Background technique
" wet process " operation in traditional architecture, i.e. cast-in-situ steel reinforced concrete operation, belong to high pollution, high energy consumption, labour it is close
Collection type operation mode, industrialization, the degree of automation are low.Prefabrication form of construction work is: the factorial production is carried out in advance,
Construction site to be transported to again to be assembled, this mode can largely reduce construction site construction waste, reduce energy consumption, have " light,
Fastly, the advantages of good, province ", therefore, assembled architecture form of construction work was obtaining rapid development in recent years.Assembled is mixed at present
The problem of Vierendeel girder, Column border node in solidifying soil construction are all made of cast-in-place mode, and Column border node easily occurs in terms of connection, i.e., can be because
Vierendeel girder, column scantling deviation and cause node error big, and give concrete vibrating band because node construction operating space is small
Carry out numerous difficulties.For this purpose, some building experts propose the methods of part novel joint or node ribbed stiffener, but still use node
Cast-in-place mode is constructed.Except through reinforcing construction quality control in cast-in-place node connection type, carry out control member dimensional discrepancy
Or guarantee outside concrete vibrating quality, measure is seldom.Traditional anti-seismic technology absorbs seismic energy by self-strength and plastic deformation
Amount makes building not collapse under big shake effect.But for highlight lines area or security level higher building such as school, doctor
Institute, market etc., traditional anti-seismic technology were difficult to coordinate to build using function and conflicting on building safety, that is to say, that build to meet
Build safety, it has to sacrifice part building function.Energy-dissipating and shock-absorbing technology then provides a kind of new Aseismic Design thinking, can make to build
It builds function and building safety obtains the coordinating and unifying.It is examined through earthquake for several times, energy-dissipating and shock-absorbing technology can effectively mitigate geological process, mention
The anti-seismic performance of high main structure reduces the life and property loss of earthquake disaster bring, has apparent economic benefit and society
Benefit.
Assembled architecture and energy-dissipating and shock-absorbing technology all have obvious social and economic benefit, at this stage if can be by two
Person organically combines, and has complementary advantages, and the application range of two kinds of technologies of great extension is preferably benefited for society.
Summary of the invention
