Description
Technical field
The present invention relates to a kind of building structure Novel superposed beam, particularly relate to a kind of steel pipe of prefabricated concrete structure and concrete folding case beam and processing method thereof.
Background technology
Assembly concrete building refers to the concrete prefabricated element based on factorial praluction, the xoncrete structure class building construction of being built by site-assembled patten's design.To water after overlapping layers concrete, Bar Anchorage pouring concrete connection etc. after the assembly method of component generally has scene, bar connecting can adopt sleeve to be in the milk to connect, welding, the way such as mechanical connection and the connection of reserving hole overlap joint.The eighties in 20th century, at the prefabricated large plate house that China is popular, due to reasons such as structural integrity is poor, seepage, cracks on floor slab, existing manyly affects structural safety and the normal hidden danger that uses and defect, gradually replace by cast-in-place concrete structure.But along with the application of current emerging prefabricated concrete structure, particularly introduced many advanced foreign technologies in recent years, localized prefabricated concrete structure is built new technology and is just progressively formed.
The trend reducing the appearance housing industry industrialization of building trade recruitment famine along with the quickening of China's " building industrialization, housing industrialization " process and the continuous of China's " demographic dividend " is day by day obvious.The application of prefabricated concrete structure becomes new technology, 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, economize energy of enhancing productivity, development Green environmental-protection building, and is 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 more can meet the saving land of green construction, energy-conservation, material-saving, the requirement such as water saving and environmental protection; reduce the negative effect to environment; comprise and reduce noise, prevent airborne dust, reduce environmental pollution, clean transport, reduce place interference, save resource and the energy such as water, electricity, material, follow the principle of sustainable development.And, fabricated construction can complete multiple or whole operations of engineering continuously in order, thus reduce the engineering machinery kind and quantity of marching into the arena, that eliminates procedure connection rests the time, realize interchange operation, reduce workmen, thus 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 and part assembling two large classes according to assemblingization degree height.Full assembling building is generally restricted to low layer or the lower tier building of requirements for fortification against earthquake; Part assembling concrete construction main member is generally adopted prefabricated components, is connected by cast-in-place concrete at the scene, forms the building of cast in place and precast construction.
North America region is mainly based on America & Canada.Because prefabricated/prestressed concrete association (PCI) studies for a long period of time and promotes pre-cast building, the Specification of precast concrete is also very perfect. so its assembly concrete Application in Building is very general.The pre-cast building of North America mainly comprises building prefabrication exterior wall and the large series of structure prefabricated components two, and the common feature of prefabricated components is that maximization and prestressing force combine, can optimize structure arrangement of reinforcement and connecting 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-antidetonation fortified defence area of low layer.Due to the earthquake effect in area, California, pay much attention to the engineer applied technical research of antidetonation and precast construction on the middle and senior level in recent years.PCI has published " precast concrete Aseismic Design " book recently, the Aseismic Design problem of pre-cast building is analyzed from theory and practice angle system, summarizing the latest scientific research of many precast construction Aseismic Design, to instructing precast construction design and engineer applied to promote, there is very strong directive significance.
Europe is the cradle of pre-cast building, just starts the road of 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 economically developed Northern Europe, West Europe, or Eastern Europe underdeveloped, always all in the design and construction mode actively carrying out prefabrication and assembly construction concrete construction.Have accumulated the design and construction experience of many pre-cast buildings, define various special precast building system and standardized general prefabricated product line, and worked out a series of precast concrete engineering specification and application manual, in global application, very important effect is served to promotion precast concrete.
Japan and Korea S have used for reference American-European successful experience, on the standardized designs construction basis exploring pre-cast building.In conjunction with oneself requirement.Breakthrough is achieved in precast construction system globality antidetonation and shock design.Representative achievement be the Tokyo Tower of two 58 floor that Japan adopts prefabrication and assembly construction frame structure to build up for 2008.Meanwhile, the standard criterion that the precast concrete building system of Japan designs, makes and constructs is also very perfect, and the prefabricated specification used at present has " precast concrete engineering " (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, define a series of assembly concrete building system, 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 all define design, make and the assembly concrete industrialized building pattern of construction and installation integration. 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%.Because the function of assembled architecture and physical property exist many limitations and deficiency, the assembly concrete architectural design of China and construction technology R & D Level also do not catch up with the change 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 comparatively extensively of assembled single storey industry workshop building system.The engineer applied of other prefabrication systems is few.The globality of precast construction antidetonation and the specialization research of management in design and operation not, cause its Technical Economy poor.It is the basic reason causing precast construction to stagnate for a long time.
