Description

A kind of frame structure prefabricated reinforced concrete triangular pedestals body
Technical field
The present invention relates to a kind of assembled architecture systems technologies, and in particular to a kind of frame structure prefabricated reinforced concrete triangle Shape bearing body.
Background technology
In order to adjust construction industry structure, construction quality is improved, Accelerating The Construction speed realizes energy conservation and environmental protection, reduces engineering Cost, country's proposition widely popularize assembled architecture, specify specific implementation plan;And it requires in reinforced concrete frame knot Extensive use in structure, reinforced concrete frame shear wall structure, steel construction and steel-concrete combined structure system specifies that China fills With formula architectural structure system and application field;But large-span steel-reinforced concrete frame structure assembled architecture ground zero, and Using common laminated floor slab and T plate superstructure technology, cause cost high, earth-free gas constrains assembled architecture industry Development.
Such as a kind of ZL200410082381.9 " hollow floor slab with small dense ribs " of inventor, hollow filling body is embedded in cast-in-situ floor Middle formation " T fonts " stress cross-section hollow layer, solves the problems, such as large span, large space, big load, is assembled architecture floor It lays a good foundation.
Again in order to promote China's housing industrialization to develop, the ZL201620408935.8 of inventor's application " build by passive type Energy saving integrated system " expands to cast-in-place concrete hollow building roof assembled architecture field by creating transition, solves Assembled arthitecutral structure globality poor, large span without bright beam, component super large, component industrialization, construction quality controllability, work efficiency and The problems such as environmental protection;These inventions, although laying the foundation for China's Process of Housing Industrialization, it is pre- that there is also long strip types Crackle, the bidirectional stress in gap when the one-way of assembled cavity plate member stress processed, two pieces of prefabricated assembled cavity plate splits The problems such as connection space of cavity floor transverse direction reinforcing bar is restricted.
In order to capture the low difficulty of steel reinforced concrete assembling building structure assembly rate, inventor applies Assembly rate, within 40% has been increased to 70% or more, has passed through state by 201710951186.2 " a kind of assembled arthitecutral structures " Family's grade experiment is checked and accepted, and safety of structure is strong and good economy performance, carries out assembled architecture for government and has played positive effect;But Beam, column, floor node are all taken at cast-in-place state, although structure safety, need a large amount of temporary support supporting beam, column, building Board member and there are many splices in Liang Yuliang, beam and column infall, bar connecting is loaded down with trivial details and cost is high.
At present, the assembled architecture of reinforced concrete frame structure also has many Ji arts Wen Ti No to have solution, causes to build Cost is high, and popularization is obstructed;Therefore, inventor is again on the basis of existing background technology self, by verification experimental verification, by beam, column, The cast-in-place concrete node region of floor, it is creative to be modified in that prefabricated reinforced concrete bearing body, enhancing shearing and resistance to flush shear force Ability, by the column of rear pouring concrete and beam stress reinforcing bar node, be dispersed in column centre and prefabricated reinforced concrete bearing body except triangle In the girder assembly side being arranged on the water chestnut of shape or triangle;Column steel bar stress passes through rectangular among prefabricated reinforced concrete bearing Crisscross beam stress reinforcing bar up extends in post holes, realizes in beam, Column border node position no-reinforcing-bar connector, greatly reduces branch Strut member and assembling speed is further speeded up, assembled quality is improved, reduces project cost;Realize that strong column and weak beam pours floor afterwards again The assembled architecture overall structure new technology of top flange overlapping layers;It is reinforced concrete frame structure and frame core wall structure dress The important breakthrough that new technology system is built with formula has become the urgent need of assembled architecture technical field innovation.
Invention content
It is an object of the invention to thoroughly solve the shearing of assembling frame Structure Beam-column node and resistance to flush shear force, reaches and carry High building quality accelerates built speed, realizes that energy conservation and environmental protection, increase assembly rate, reduction cost and structure are safe and reliable;Play wound The advantage of new assembled Building technology, the shortcomings that overcoming the prior art;Prefabricated reinforced concrete bearing body, the column of factorial praluction The prefabricated components such as frame, girder, cavity board member, stair, wallboard, after assembled in situ, then outside prefabricated reinforced concrete bearing body In node, column frame, the connection spaces rear pouring concrete such as the top flange of building floor, realize that strong column and weak beam pours floor top flange overlapping afterwards again The assembled architecture overall structure new technology of layer;Reduce a large amount of supporting bar and easy construction process;By available frame knot Structure, frame core wall structure, steel construction assembled laminated floor slab and T plate superstructure technology, transition and upgrade are a kind of band pre-manufactured steel The assembled architecture technology of muscle concrete bearing body;Reach the existing assembled arthitecutral structure technical system of optimization, overcomes existing structure A series of defects existing for technology.
