Description
Technical field
The present invention relates to a kind of assembled architecture systems technology, and in particular to a kind of prefabricated hollow column technology.
Background technology
Country widelys popularize assembled architecture, specify that specific implementation plan；And require in reinforced concrete frame knot
Extensive use in structure, reinforced concrete frame shear wall structure, steel construction and steel-concrete combined structure system, it specify that China fills
With formula architectural structure system and application field；But the assembled architecture floor ground zero of large span horizontal structure, and use
Be common laminated floor slab, technology existing defects, assembled architecture cost is too high, earth-free gas, cause country promote assembled
Built speed is obstructed.
Prior art is using common beam slab such as a kind of ZL200410082381.9 " empty stomach little Mi Lei buildings of inventor
Lid " and ZL200820126232.1 " a kind of cast-in-situ section steel concrete cavity building roof ", hollow filling body is embedded in shape in cast-in-situ floor
Into " T fonts " stress cross-section hollow layer, solve the problems, such as large span, large space, big load.In order that girt strip reinforcing bar leads in length and breadth
Steel I-beam web is crossed, forms the cast-in-situ hollow floor plate of continuous slab band, the too many simultaneously aperture in the hole reserved in steel I-beam web
It is too small, processing trouble；Meanwhile the cement hollow obturator setting and hardening time is grown, mould utilization factor is low, and hollow filling volume density is big
Matter weight, production and transport inconvenience and the defects of obturator globality poor cracky.
To realize industrialized production, inventor applies for that ZL201310332173.9 " use by a kind of cast-in-situ hollow building roof pore-forming again
Netted box component " and ZL201510331724.X " a kind of Novel steel-mixed combination cast-in-situ hollow building roof ", to it is existing pour it is hollow
Superstructure technology carries out General Promotion, realizes transition and upgrade, updates and significantly reduce the deadweight of cavity building roof, add
Self-heat preservation heat insulation performance, safety of structure is strong, solve realize large span, large space, big load hollow floor existing for ask
Topic；Inventor constantly lifts oneself cast-in-situ hollow building roof background technology, is assembled architecture large span, the horizontal structure without bright beam
The basis of hard stone is established；Although solving the problems, such as into pole production, all it is cast-in-site, dress is pushed away by force with country
It is not inconsistent with formula spirit.
Again in order to promote China's housing industrialization development, " one kind is used for sky to the ZL201620410363.7 of inventor's application
The prefabricated component of chamber superstructure " and ZL201620553181.5 " a kind of stress island cavity building roof prefabricated cavity member "
Cast-in-place concrete hollow building roof, assembled architecture field is expanded to by creating transition, solve assembled arthitecutral structure entirety
The problems such as poor, large span of property is without bright beam, component super large, component industrialization, construction quality controllability, work efficiency and environmental protection；This
, although having tamped basis for China's Process of Housing Industrialization, the prefabricated assembled cavity plate structure of long strip type also be present in a little inventions
The crackle in gap, bidirectional stress cavity floor transverse direction steel when the one-way of part stress, two pieces of prefabricated assembled cavity plate splits
The problems such as connection space limitation of muscle.
Currently, since prefabricated member also has many Ji arts Wen Ti No to have solution, popularization is caused to be obstructed；In order to promote to build
Scientific and technological progress, use is multi-functional, economy, scientific and technological content, energy-conserving and environment-protective and the market demand are big, safety coefficient is high, cost
It is low, meet the architectural structure system of national industrial policies and industrial development direction again.Therefore, inventor is again in existing background of controlling oneself
On the basis of technology, by being applied in assembled arthitecutral structure for cast-in-situ hollow building roof technology creation, new assembling is formed
Formula cassette ceiling structural system；Cast-in-place cavity building roof Technology Difficulties problem is solved in batch production, sizing production prefabricated post, prefabricated
Beam, assembled cavity floor component, steel structure member, structure be integrally forced through behind scene pour top flange plate and combination girt strip or
Prestressed mode solves, the prefabricated assembled Cavity structural member of factorial praluction and steel construction and the organic knot of reinforced concrete frame
Altogether；Again in order to promote China's housing industrialization to develop in a healthy way, recently, inventor participates in big by Tongji University in oneself production base
, civil construction institute of Central South University, national Tianjin fire research preside over largest " assembled large span is without secondary beam
Steel construction cavity floor full scale test ", " assembled large span is without bright joist steel tendon concrete structure full scale test ", " utilization assembling
The fire control smoke exhausting experiment of formula cavity floor " examines inventor's prior art innovative, advanced, reasonability and security；Examination
Test the multispan load pressurization full scale test and Assembled Building plate ultimate load loading full scale test using continuous slab band, ultimate load
The specific data of load test be done without beam assembled experimental model span 8.4m, surrounding encorbelment 1.6m, length of side 11.6m, by
Pressure surface accumulates 134.56m2, use dynamic load 2KN, actual loaded load 22KN；Limit crack national standard is 1.5mm, and actual crack is only
There is 0.5mm；It is 168mm, actural deflection 39mm by national standard calculating limit amount of deflection；Assembled architecture is in reinforcing bar by verification experimental verification
Security of the concrete structure without the structure of bright beam or steel construction without secondary beam；Single load bearing floor member is changed into by verification experimental verification
Bidirectional stress floor, the floor construction that monolithic freely-supported floor member is changed into continuous slab band；Thoroughly solves large span floor structure
The problems such as part bonding crack cracking, fire prevention, sound insulation, long-term maintenance, assembly technology, particularly assembled architecture cost have dropped
20%；Logical structure full scale test, further innovates for assembled architecture and has tamped practical basis；But experiment discloses assembled
The distribution of building structure internal force becomes rule, and also in the case where ensuring the preceding topic of assembled arthitecutral structure safety requirements, assembled is built
Build the space that technology also much optimizes.A kind of prefabricated open tubular column is researched and developed, has become assembled architecture technical field
The urgent need of innovation.
