Description

A kind of assembly concrete node
Technical field
The utility model belongs to technical field of buildings, more particularly to a kind of assembly concrete node and its dry type connection Method.
Background technology
Assembly concrete building refers to pass through site-assembled side by main of the concrete prefabricated element of factorial praluction The concrete structure class building construction of formula design-build.The assembly method of component, which typically has, pours overlapping layer concrete, steel behind scene Pouring concrete connection etc. after muscle is anchored, bar connecting can be connected using sleeve grouting, welded, mechanically connected and reserving hole overlap joint The ways such as connection.In the 1980s, in the popular prefabricated big plate house of China, because structural integrity is poor, seepage, , there is many influence structure safety and the hidden danger and defect that normally use, gradually by cast-in-place concrete knot in the reasons such as cracks on floor slab Structure is replaced.But with the application of current emerging prefabricated concrete structure, particularly introduce many external first in recent years Enter technology, localized prefabricated concrete structure is built new technology and 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 trades recruitment is increasingly obvious.The application weight of prefabricated concrete structure Newly the new technology of residential housing prefabricated concrete structure, new model are continued to bring out out as current research focus  all parts of the country. Precast reinforced concrete structure is one of important directions of China's building structure development, and it is conducive to China's building industrialization Development, improves production efficiency and saves the energy, develop Green environmental-protection building, and be conducive to improving and ensureing 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, save, saving the requirement such as material, water saving and environmental protection, reduce negative effect to environment, including reduction noise, prevent Resource and the energy such as airborne dust, reduction environmental pollution, cleaning transport, the interference of reduction place, saving 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 procedure connection rests the time, realizes interchange operation, reduces workmen, It is that green construction provides safeguard so as to improve work efficiency, reduction supplies consumption, reduce environmental pollution.In addition, fabricated construction compared with Reduce building waste (account for municipal refuse total amount 30% -40%) in big degree, such as steel scrap muscle, waste iron wire, useless bamboo wood material, useless Abandon concrete etc..
Assembly concrete building can be divided into two major classes of full assembling and part assembling according to assembling degree height.Full assembling Building is generally limited to low layer or the relatively low tier building of requirements for fortification against earthquake;Part assembling concrete construction main member is general Connected using prefabricated components, at the scene by cast-in-place concrete, form the building of cast in place and precast construction.
North America region is mainly by main of America & Canada because prefabricated/prestressed concrete association (PCI) studies for a long period of time With promoting 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 the big series of building prefabrication exterior wall and structure prefabricated components two, and prefabricated components are total to It is that maximization and prestressing force are combined and can optimize structural reinforcement and connecting structure with feature.Reduce and make and installation workload, contracting The short Yi works duration, fully demonstrate 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 is paid much attention in recent years and on the middle and senior level prefabricated The engineer applied technical research of structure.PCI is published recently《Precast concrete Aseismic Design》One book, from theory and practice Analyze the Aseismic Design problem of pre-cast building, the newest section for summarizing many precast construction Aseismic Designs is ground into angle system Really, to instructing, precast construction is designed and engineer applied is promoted with very strong directive significance.
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 pattern.Either economically developed north Europe, West Europe, or Eastern Europe underdeveloped, are all actively carrying out the design and construction side of prefabrication and assembly construction concrete construction always Formula.Have accumulated the design and construction experience of many pre-cast buildings, form various special precast building systems and standardization it is general Pre-manufactured product series, and a series of precast concrete engineering specifications and application manual have been worked out, to promoting precast concrete complete The application in the world serves very important effect.
Japan and South Korea have used for reference the successful experience of America and Europe, on the basis of the standardized designs construction of pre-cast building is explored. With reference to 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, Japanese is pre- Concrete construction System Design processed, the standard criterion for making and constructing are also very perfect, and the prefabricated specification used at present has《It is prefabricated mixed Solidifying geotechnique's journey } (JASSl0) and《Concrete curtain wall) (JASSl4).
China from the sixties in 20th century five begin one's study assembly concrete building design and construction technology, form one Serial assembly concrete building system, more typical building system has assembled single storey industry workshop building system, assembling Formula multistory frame building system, assembled large panel building system etc..The application built to 1980s assembly concrete The period of full bloom is reached, many places in the whole nation all form the assembly concrete industry of design, making and construction and installation integration Change architectural mode assembly concretes building and two kinds of topmost building bodies are turned into using the masonry building of prefabricated hollow floor System, application popularization rate is up to more than 70%.Because there is many limitations and deficiency, China in 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 change, To 1990s mid-term, 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 applied of other prefabrication systems is few.In advance The globality of structural seismic 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.
