Description

A kind of assembly concrete column beam connecting node
Technical field
The present invention relates to a kind of building energy conservation walls, more particularly to a kind of assembly concrete column beam connecting node.
Background technique
It is that main passes through site-assembled side that assembly concrete building, which refers to the concrete prefabricated element of the factorial production, 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 " The trend of the waste appearance housing industry industrialization of few building trade recruitment is increasingly obvious.The application weight of prefabricated concrete structure Newly become all parts of the country current research hot spot and continues to bring out out the new technology of residential housing prefabricated concrete structure, new model. 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.
