Description
Technical field
The present invention relates to assembly concrete girders and secondary beam dry type connecting node, belong to building structure field.
Background technique
Assembly concrete building refers to based on the concrete prefabricated element with the factorial production, passes through site-assembled side
The concrete structure class building construction of formula design-build.The assembly method of component pours overlapping layer concrete, steel after generally having scene
Sleeve grouting connection, welding, mechanical connection and reserving hole overlap joint can be used in pouring concrete connection etc. after muscle anchoring, reinforcing bar connection
The ways such as connection.In the 1980s, in the prefabricated big plate house of China's prevalence, due to structural integrity is poor, leakage,
The reasons such as cracks on floor slab, there are many influence structure safety and the hidden danger and defect of normal use, gradually by cast-in-place concrete knot
Replaced structure.But it with the application of current emerging prefabricated concrete structure, especially introduces in recent years many external first
Into technology, localized prefabricated concrete structure is built new technology and is just gradually formed.
With the quickening of China " building industrialization, housing industrialization " process and constantly subtracting for China's " demographic dividend "
Less, the appearance of building trade recruitment famine, the trend of housing industry industrialization are increasingly obvious.The application weight of prefabricated concrete structure
Newly become current research hot spot, all parts of the country continue to bring out out new technology, the new model of residential housing prefabricated concrete structure.
Precast reinforced concrete structure is one of the important directions of China's building structure development, it is conducive to China's building industrialization
Development, raising production efficiency is energy saving, develops Green environmental-protection building, and is conducive to improve and guarantee construction engineering quality.
Compared with cast-in-situ construction method, assembled reinforced concrete structure is conducive to green construction, because fabricated construction can more meet green construction
Save land, energy conservation, section material, water-saving and environmental protection etc. require, reduce the negative effect to environment, including reduce noise, prevent
Fugitive dust reduces environmental pollution, cleans transport, reduce place interference, save resources and the energy such as water, electricity, material, it then follows sustainable
The principle of development.Moreover, fabricated construction can continuously complete multiple or whole processes of engineering in order, thus reduce into
The engineering machinery type and quantity of field eliminate resting the time for procedure connection, realize interchange operation, reduce construction personnel,
To improve work efficiency, reduction supplies consumption, reduce environmental pollution, provided safeguard for green construction.In addition, fabricated construction compared with
Building waste (account for about municipal refuse total amount 30% -40%) is reduced in big degree, such as steel scrap muscle, waste iron wire, useless bamboo wood material, is given up
Abandon concrete etc..
Assembly concrete building can be divided into full assembly and part assembly two major classes according to assembling degree height.Full assembly
Building is generally limited to low layer or the lower tier building of requirements for fortification against earthquake;Part assembly concrete construction main member is general
It is connected using prefabricated components, at the scene by cast-in-place concrete, forms the building of cast in place and precast construction.
North America region is mainly main since prefabricated/prestressed concrete association (PCI) studies for a long period of time with America & Canada
With popularization pre-cast building, the Specification of precast concrete also improves very much so its assembly concrete Application in Building is non-
It is often universal.The pre-cast building of North America mainly includes building prefabrication exterior wall and the big series of structure prefabricated components two, and prefabricated components are total to
It is that enlargement and prestressing force combine and can optimize structural reinforcement and connecting structure with feature.Reduce production and installation workload, contracting
The short Yi work duration fully demonstrates industrialization, standardization and Technical Economy feature.In 20th century, the pre-cast building of North America is main
For the non-antidetonation fortified defence area of low layer.Due to the earthquake effect in California area, antidetonation and on the middle and senior level prefabricated is paid much attention in recent years
The engineer application technical research of structure.PCI has published " precast concrete Aseismic Design " book recently, from theory and practice
The Aseismic Design problem for analyzing to angle system pre-cast building, the newest section for summarizing many precast construction Aseismic Designs are ground into
Fruit has very strong directive significance to instructing precast construction design and engineer application to promote.
Europe is the cradle of pre-cast building, and the road of building industrialization has been begun to early in the 17th century.Second of the world is big
After the war, due to human resources shortage, Europe further research and probe building industrialization mode.Either economically developed north
Europe, West Europe or Eastern Europe underdeveloped, always all in the design and construction side for actively carrying out prefabrication and assembly construction concrete construction
Formula.The design and construction experience for having accumulated many pre-cast buildings forms various special precast building systems and standardized general
Pre-manufactured product series, and a series of precast concrete engineering specifications and application manual have been worked out, to promotion precast concrete complete
The application in the world plays the role of very important.
Japan and South Korea have used for reference American-European successful experience, on the basis of exploring the standardized designs construction of pre-cast building.
In conjunction with oneself requirement.Breakthrough is achieved in terms of precast construction system globality antidetonation and shock design.With representative
Property achievement two 58 floor for being Japan 2008 and being built up using prefabrication and assembly construction frame structure Tokyo Tower.Meanwhile it is Japanese pre-
Concrete construction System Design processed, production and the standard criterion of construction are also very perfect, and prefabricated specification used at present has " prefabricated mixed
Solidifying geotechnique's journey } (JASSl0) and " concrete curtain wall) (JASSl4).
China from five sixties of 20th century begin one's study assembly concrete build design and construction technology, form one
Serial assembly concrete building system, more typical building system have assembled single storey industry workshop building system, assembly
Formula multistory frame building system, assembled large panel building system etc..The application built to assembly concrete the 1980s
Reach the period of full bloom, many places in the whole nation all form the integrated assembly concrete industry of design, production and construction and installation
Change architectural mode assembly concrete building and two kinds of most important building bodies are become using the masonry building of prefabricated hollow floor
System, application popularization rate is up to 70% or more.Since there are many limitations and deficiency, China for the function and physical property of assembled architecture
Assembly concrete architectural design and construction technology R & D Level do not catch up with also social demand and Building technology development variation,
To mid-term the 1990s, assembly concrete building is gradually replaced by full cast-in-place concrete building system, at present except dress
With formula single storey industry workshop building system using wide outer.The engineer application of other prefabrication systems is few.In advance
The globality of earthquake-resistant structure processed and the specialized research of management in design and operation are inadequate, cause its Technical Economy poor.It is to cause
The basic reason that precast construction stagnates for a long time.
