Description
Technical field
The present invention relates to a kind of building structure Novel superposed beam, particularly relate to a kind of steel pipe and concrete folding case beam and processing method thereof of prefabricated concrete structure.
Background technology
Assembly concrete building refers to take concrete prefabricated element that batch production produces as main. by the xoncrete structure class building construction of site-assembled mode design-build.The assembly method of member generally has waters after overlapping layers concrete, Bar Anchorage pouring concrete connection etc. behind scene, and reinforcing bar connects ways such as can adopting sleeve grouting connection, welding, mechanical connection and the connection of reserving hole overlap joint., due to reasons such as structural integrity is poor, seepage, cracks on floor slab, there are many structural safety and normal hidden danger and defects of using of affecting in the popular prefabricated large plate house of ， China eighties in 20 century, is replaced gradually by cast-in-place concrete structure.But along with the application of current emerging prefabricated concrete structure, particularly introduced in recent years many advanced foreign technologies, localized prefabricated concrete structure is built new technology and is just progressively formed.
Along with the trend of the appearance house industrial sector of the continuous minimizing building trade recruitment famine of the quickening of China's " building industrialization, housing industrialization " process and China's " demographic dividend " is day by day obvious.The application of prefabricated concrete structure becomes new technology, the new model that current research focus all parts of the country continue to bring out out residential housing prefabricated concrete structure again.Precast reinforced concrete structure is one of important directions of China's building structure development, and it is conducive to the development of China's building industrialization, the saving energy of enhancing productivity, and development Green environmental-protection building, and be conducive to improve and guarantee construction engineering quality.Compare with cast-in-situ construction method; assembled reinforced concrete structure is conducive to green construction; because fabricated construction more can meet the requirements such as the saving land of green construction, energy-conservation, material-saving, water saving and environmental protection; the negative effect of reduction to environment; comprise reduction noise, prevent airborne dust, reduce environmental pollution, clean transportation, reduce place interference, save resource and the energy such as water, electricity, material, follow the principle of sustainable development.And, fabricated construction can complete a plurality of or whole operations of engineering continuously in order, thereby reduce engineering machinery kind and the quantity of marching into the arena, eliminate resting the time of procedure connection, realize interchange operation, reduce workmen, thereby improve work efficiency, reduction supplies consumption, minimizing environmental pollution, for green construction provides safeguard.In addition, fabricated construction reduces building waste (accounting for the 30%-40% of municipal refuse total amount) largely, as steel scrap muscle, waste iron wire, useless bamboo timber, discarded concrete etc.
Assembly concrete building can be divided into full assembling according to assemblingization degree height and part is assembled two large classes.Full assembling building is generally restricted to low layer or the lower tier building of requirements for fortification against earthquake; Part is assembled concrete construction main member and is generally adopted prefabricated components, by cast-in-place concrete, connects at the scene, forms the building of cast in place and precast construction.
North America region mainly be take America & Canada as main. because prefabricated/prestressed concrete association (PCI) studies for a long period of time and promotes pre-cast building, so the Specification of precast concrete is also very perfect. and its assembly concrete Application in Building is very general.The pre-cast building of North America mainly comprises the large series of building prefabrication exterior wall and structure prefabricated components two, and the common feature of prefabricated components is to maximize to combine with prestressing force. can optimize structure arrangement of reinforcement be connected structure.Reduce and make and installation workload, shorten the Yi work duration, fully demonstrate industrialization, standardization and Technical Economy feature.In 20th century, the pre-cast building of North America is mainly used in the non-area of providing fortification against earthquakes of low layer.Due to the earthquake effect in area, California, pay much attention in recent years the engineering application technical research of antidetonation and precast construction on the middle and senior level.PCI has published < < precast concrete Aseismic Design > > mono-book recently, from theory and practice angle, systematically analyzed the Aseismic Design problem of pre-cast building, summed up the latest scientific research of many precast construction Aseismic Design, to instructing precast construction design and engineering application to there is very strong directive significance.
Europe is the cradle of pre-cast building, the road that has just started building industrialization as far back as the 17th century.After World War II, due to human resources shortage, Europe is research and probe building industrialization pattern further.No matter be economically developed Northern Europe, West Europe, or Eastern Europe underdeveloped, all actively carrying out the design and construction mode of prefabrication and assembly construction concrete construction always.Accumulated the design and construction experience of many pre-cast buildings, various special precast building systems and standardized general prefabricated product line have been formed, and worked out a series of precast concrete engineering specifications and application manual, to promoting precast concrete, in global application, played very important effect.
Japan and Korea S have used for reference American-European successful experience, are exploring on the standardized designs construction basis of pre-cast building.In conjunction with oneself requirement.In precast construction system globality antidetonation and shock insulation design aspect, obtained breakthrough.Representative achievement be the Tokyo Tower that Japan adopts two 58 floor that prefabrication and assembly construction frame structure builds up for 2008.Simultaneously, the precast concrete building system design of Japan, make and the standard criterion of construction also very perfect, the prefabricated standard of using at present has < < precast concrete engineering } (JASSl0) and < < concrete curtain wall) (JASSl4).
China is from the begin one's study design and construction technology of assembly concrete building of five sixties of 20th century, formed a series of assembly concrete building systems, comparatively typical building system has assembled single storey industry workshop building system, assembled multistory frame building system, assembled large panel building system etc.To the eighties in 20th century, the application of assembly concrete building reaches the period of full bloom, many places, the whole nation have all formed the integrated assembly concrete industrialized building of design, making and construction and installation pattern. and the masonry building of assembly concrete building and employing prefabricated hollow floor becomes two kinds of topmost building systems, and application popularization rate reaches more than 70%.Owing to there is many limitations and deficiency in function and the physical property of assembled architecture, the assembly concrete architectural design of China and construction technology R & D Level also do not catch up with the variation of social demand and Building technology development, to the mid-90 in 20th century, assembly concrete building is replaced by full cast-in-place concrete building system gradually, at present except the application extensively of assembled single storey industry workshop building system.The engineering application of other prefabrication systems is few.The globality of precast construction antidetonation and the specialization of management in design and operation research not, cause its Technical Economy poor.It is the basic reason that causes precast construction to stagnate for a long time.
