Description
Technical field
The utility model relates to a kind of concrete frame structure system, belongs to building field.
Background technology
At home, the sustainable development of real estate, greatly driven the growth of domestic economy, national strength strengthens day by day.But while economy rapidly increases, the fact that environment goes from bad to worse progressively is put in face of compatriots.Let us is had to our behavior of serious soul-searching, starts to pursue a kind of sustainable development route simultaneously.
Builing industry is the important substance production division of national economy, and with the development of whole national economy, the improvement of people's lives has close relationship.But in the face of the scarcity day by day with labour that consumes excessively of resource environment, builing industry is transition and upgrade urgently, and architectural industrialization has become the inexorable trend of industry development.Advancing architectural industrialization greatly will promote energy-saving and emission-reduction, advance green safety construction, promote housing quality, improve human settlement, promote construction industry industry restructuring, is the effective way realizing green low-carbon building.
In propelling architectural industrialization process, all kinds of integrated technique, assembled architecture technology are as emerged rapidly in large numbersBamboo shoots after a spring rain; Popularity is started in housing construction industrialization.But public building, industrial construction are as the important component part of builing industry, and its industrialization level but lags far behind, and because its function is to the particular/special requirement in space, prior art still has significant limitation.The contradiction of engineering structures span and construction costs, the contradiction of engineering construction cycle and production time or business hours, is badly in need of seeking a kind of new building system and solves these problems.
" energy-conservation, consumption reduction, reduce discharging, environmental protection " fundamental state policy for implementing, realize the sustainable development of natural resources and energy resources, country is advancing the modernization of building industry with all strength, improves industrialized level.Assembled architecture have industrialized level high, be convenient to winter construction, reduce job site wet trade amount, reduce material consumption, reduce the advantage such as dust from construction sites and building waste, it is conducive to the object realizing improving construction quality, enhance productivity, reduce costs, realize energy-saving and emission-reduction and protection of the environment.
In recent years, due to the raising that energy-saving and emission-reduction state basic policy requires, and significantly the going up of the price of labour power, simultaneously due to the popularity of advanced technology in fabricated construction, the application of fabricated construction starts to break away from low ebb, presents the trend risen rapidly.Assembled architecture is mainly applicable to all kinds of civilian construction of below Class B that non-seismic design and seismic fortification intensity are 6-8 degree seismic design area and Class B at present.Comprising residential building and public building.Structural system mainly comprises: prefabricated integral frame structure, assembled integral shear wall structure, prefabricated integral frame-shear wall structure etc.
The application of assembled architecture in industrial construction and public building is much inferior, and the industrialization process speed as the pillar field industrial construction in builing industry and public building is slow.Because industrial construction generally requires comparatively large (because production technology needs) the span of structural system, the large span industrial construction majority of present stage is steel-structure factory building, concrete structure realizes comparatively difficulty, and the factory building majority of general span more than 18 meters is steel-structure factory building.Concrete structure rarely has realization.Public building such as exhibition room, parking building etc. require also higher to structural span, but due to the limitation of prior art, make designer have to when designing consider structural cost problem, thus such building using function is shunk greatly.
How advance the industrialization process of industrial construction and public building fast, realize large span simultaneously, reduce costs, shorten construction period, this is urgent problem in industrial construction and public building.
At present, a kind of longspan structure system generally adopted in single storey industry workshop is: " cast-in-place framed bent+prefabricated T plate " form of structure.
T plate: because of its form of fracture similar " double T ", therefore gain the name.T plate is precast unit.Span of slab can realize more greatly less than 27 meters spans, is technology more ripe in current longspan structure system.
As shown in Figure 1, 2, 3, " cast-in-place framed bent+prefabricated T plate system " comprises frame column 1, Vierendeel girder 2, T plate 3, and Vierendeel girder 1 and frame column 2 are overall cast-in-place shaping.T plate 3 is with Vierendeel girder 2 for bearing, and all reserved weldment of T plate 3 girt strip root, Vierendeel girder 2 relevant position, by being welded to connect.
There are two large technical problems in cast-in-place framed bent+prefabricated T plate system: one is poor seismic behavior; Two is that floor cracking phenomena is serious.
Although cast-in-place framed bent frame column, beam are cast-in-site, but because between upper Pin framed bent and lower Pin framed bent, span is too large, general all between 18 to 27 meters, connect too weak, very weak to the horizontal seismic force energy dissipation capacity in this direction, then add floor and be prefabricated T plate, and the connection of framed bent beam is very weak, cause integrality performance of the structure poor, general all suggestion in earthquake protection region adopts this form of structure now.
Because T plate is precast floor slab, the edge of a wing of encorbelmenting, the both sides of T plate is very thin, and due to component be prestressed member, because the impact of prestressed structure antiarch, floor out-of-flatness, when splicing between T plate and T plate, because respective antiarch degree is different, cause stitching position always crack.A lot of inconvenience is brought to the use in later stage.
This system is large because of the cast-in-place engineering quantity of its main body, therefore can not be considered as prefabricated integral frame structure.Therefore do not possess advantage and the feature of industrialized building.
