Description

Assemble type concrete slab connecting node

Technical field

The utility model belongs to building structure technology field, more particularly to assemble type concrete slab 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.

With the quickening of China " building industrialization, housing industrialization " process, the trend day of housing industry industrialization gets brighter It is aobvious.The application of prefabricated concrete structure becomes current research hot spot again, and all parts of the country continue to bring out out residential housing assembly The new technology of formula concrete structure, new model.Precast reinforced concrete structure is the important directions of China's building structure development One of, it is conducive to the development of China's building industrialization, and raising production efficiency is energy saving, develop Green environmental-protection building, and Be 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 The saving land of green construction, energy conservation, section material, water-saving and environmental protection etc. can more be met for fabricated construction to require, reduced to environment Negative effect, including reduce noise, prevent fugitive dust, reduce environmental pollution, clean transport, reduce place interfere, saving water, The resources such as electricity, material and the energy, it then follows the principle of sustainable development.Moreover, fabricated construction can be completed continuously in order Multiple or whole processes of engineering, to reduce the engineering machinery type and quantity marched into the arena, that eliminates procedure connection rests the time, It realizes interchange operation, reduces construction personnel, to improve work efficiency, reduce supplies consumption, reduce environmental pollution, applied for green Work provides safeguard.In addition, fabricated construction, which largely reduces building waste, (accounts for about the 30%-of municipal refuse total amount , such as steel scrap muscle, waste iron wire, useless bamboo wood material, discarded concrete 40%).

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.To mid-term the 1990s, assembly concrete building is gradually by complete cast-in-place coagulation Native building system replaces, at present except assembled single storey industry workshop building system is using in addition to wide.Other are prefabricated assembled to build The engineer application of building body system is few.The globality of precast construction antidetonation and the specialized research of management in design and operation are inadequate, cause Its Technical Economy is poor.It is the basic reason for causing precast construction to stagnate for a long time.
