Description
Technical field
This utility model is related to a kind of building energy conservation body of wall, the assembled coagulation that more particularly to a kind of energy saving building is adopted
Tu Liang.
Background technology
Assembly concrete building is referred to based on the concrete prefabricated element with factorial praluction. by site-assembled side
The xoncrete structure class building construction of formula design-build.The assembly method of component pours overlapping layer concrete, steel after typically having scene
Pouring concrete connection etc. after muscle anchoring, bar connecting can adopt sleeve grouting connection, welding, be mechanically connected and reserving hole overlap joint
The ways such as connection.The eighties in 20th century, in the prefabricated big plate house that China is popular, as structural integrity is poor, seepage,
, there is many hidden danger for affecting structure safe and normally using and defect, gradually tied by cast-in-place concrete in the reasons such as cracks on floor slab
Structure is replaced.But the application with currently emerging prefabricated concrete structure, has particularly been introduced many external first in recent years
Enter technology, localized prefabricated concrete structure is built new technique and just gradually formed.
With China's " building industrialization, housing industrialization " quickening of process and constantly subtracting for China " demographic dividend "
The trend of the waste appearance housing industry industrialization of few building trade recruitment is day by day obvious.The application weight of prefabricated concrete structure
Newly become current research focus all parts of the country and continue to bring out out the new technique of residential housing prefabricated concrete structure, new model.
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, improve production efficiency energy saving develop Green environmental-protection building, and are conducive to improving and ensure 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 conservation etc. are required, reduce the negative effect to environment, including reducing noise, preventing
Resource and the energy such as airborne dust, minimizing environmental pollution, cleaning transport, the interference of minimizing place, saving water, electricity, material, it then follows sustainable
The principle of development.And, fabricated construction continuously can complete multiple or whole operations of engineering in order, so as to reduce into
The engineering machinery type and quantity of field, eliminate procedure connection rest the time, realize interchange operation, reduce workmen,
So as to improving work efficiency, reducing supplies consumption, reduce environmental pollution, it is that green construction provides safeguard.In addition, fabricated construction compared with
Reduce building waste (accounting for 30%-the 40% of municipal refuse total amount) 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 big class of full assembling and part assembling according to assembling degree height.Full assembling
Building is generally limited to the relatively low tier building of low layer or requirements for fortification against earthquake；Part assembling concrete construction main member is general
Using prefabricated components, connected by cast-in-place concrete at the scene, form the building of cast in place and precast construction.
North America region is mainly based on America ＆ Canada. as prefabricated/prestressed concrete association (PCI) studies for a long period of time
With promote pre-cast building, the Specification of precast concrete is also very perfect. so its assembly concrete Application in Building is non-
Often universal.The pre-cast building of North America mainly includes two big series of building prefabrication exterior wall and structure prefabricated components, and prefabricated components are total to
It is that maximization and prestressing force combine with feature. structural reinforcement and connecting structure can be optimized.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 and on the middle and senior level prefabricated is paid much attention in recent years
The engineer applied technical research of structure.PCI is published recently《Precast concrete Aseismic Design》One book, from theory and practice
The Aseismic Design problem of pre-cast building is analyzed angle system, and the newest section for summarizing many precast construction Aseismic Designs is ground into
Really, there is very strong directive significance to instructing precast construction design and engineer applied to promote.
Europe is the cradle of pre-cast building, has begun to the road of building industrialization early in the 17th century.Second 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, always all in the design and construction side for actively carrying out prefabrication and assembly construction concrete construction
Formula.The design and construction experience of many pre-cast buildings is have accumulated, various special precast building systems and standardized general are defined
Pre-manufactured product series, and a series of precast concrete engineering specifications and application manual has been worked out, to promoting precast concrete complete
The application in the world serves very important effect.
Japan and Korea have used for reference the successful experience of America and Europe, on the basis of the standardized designs construction for exploring pre-cast building.
In conjunction with oneself requirement.Breakthrough is achieved in terms of precast construction system globality antidetonation and shock design.Have and represent
Property achievement be the Tokyo Tower of two 58 floor that Japan is built up for 2008 using prefabrication and assembly construction frame structure.Meanwhile, Japanese is pre-
The standard criterion of concrete construction System Design processed, making and construction is also very perfect, and the prefabricated specification for using 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 building design and construction technology, define one
Serial assembly concrete building system, more typical building system have assembled single storey industry workshop building system, assembling
Formula multistory frame building system, assembled large panel building system etc..Application to the assembly concrete building eighties in 20th century
The period of full bloom is reached, many places in the whole nation all define the assembly concrete industry of design, making and construction and installation integration
Change architectural mode. assembly concrete building and the masonry building using prefabricated hollow floor become two kinds of topmost building bodies
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 also do not catch up with social need and Building technology development change,
To the mid-90 in 20th century, assembly concrete building is gradually replaced by full cast-in-place concrete building system, at present except dress
Wide outer with formula single storey industry workshop building system application.The engineer applied of other prefabrication systems is few.In advance
The specialized research of the globality of structural seismic processed and management in design and operation not enough, causes its Technical Economy poor, is to cause
The basic reason that precast construction stagnates for a long time.
