Technical field
The present invention relates to a kind of frame structure system, especially with prestressed assembly formula truss-like steel reinforced concrete knot
Structure system and its assembling method.
Background technology
1974, what the United Nations published《The policy of building industrialization is done step-by-step in government and measure is guided》Defined in build
Build industrialization：Construction industry is transformed according to big industrial mode of production, is allowed to progressively turn to the big production of socialization from handicraft production
Process, its implementation process are architectural design standard, component and fitting production plant, mechanization of building operation and organization and administration science
Change, and progressively use the new results of modern science and technology, to raise labour productivity, Accelerating The Construction speed, reduce engineering cost,
Improve construction quality.
In recent years, China's economic total volume quickly increases, and the scale of infrastructure occupy world forefront, building industry work always
The demand of industry is more and more urgent.Precast assembly structural system can embody industrialized production feature well, be recent heat
Point studies a question.However, the assembly of concrete structure needs wet construction, substantial amounts of wet construction can not embody the excellent of assembled system again
More property；Steel construction optimum is used to industrialize assembled production, but its anti-corrosion, fire safety problem allow people's headache again.This is just needed will be mixed
Solidifying soil and steel construction mix to form the shortcomings that steel reinforced concrete system is to evade when it works independently.
Design for steel reinforced concrete system,《Steel reinforced concrete structure technical regulation》（YB 9082-2006）Deng one
Related design code and detailing requiments are all proposed to it in a little technical specification codes.The technical problem that presently, there are is：Steel
The industrialization of bone concrete system, assembling degree be not also high, causes construction speed and production efficiency relatively low, simultaneously for some
Span is relatively large and the building for the load that takes the weight, the reinforcing bar coagulation gone out in design using such design discipline and Specification Design
Often there are the problems such as size is larger, amount of deflection is larger for soil body system.
The content of the invention
It the object of the present invention is to provide a kind of pin-connected panel reinforcing bar concrete structural system, can build steel reinforced concrete structure
Build field more industrialize, assembling, to improve its construction speed and production efficiency.Another object of the present invention is to solve
Span is relatively large and the building for the load that takes the weight in, the scantling designed according to common reinforcing bar concrete design method
Larger, the problems such as degree of disturbing is larger, propose that one kind applies prestressed method in steel reinforced concrete structure system.
Technical scheme is as follows：A kind of prestressed assembly formula truss-like steel reinforced concrete structure system, its feature
It is, including steel reinforced concrete girder segment, steel framed concrete section and the deformed bar formed by prefabrication, institute
State steel reinforced concrete girder segment, the end of steel framed concrete section is equipped with gusset plate and is connected for wet joint；The steel
Bone beams of concrete segment, the beam section part of steel framed concrete section are equipped with prestressed pore passage, and the gusset plate uses high

It is fixed, form integral frame structure system.
Further, the prestressed pore passage is located at lower part, positioned at upper at bearing into undulated arrangement at span centre
Portion, all the time in tension position.
Further, the steel framed concrete section includes joist steel truss, column steel truss, and the joist steel truss is worn
The hole reserved on column steel truss, pouring concrete after positioning are crossed, the gusset plate for reserving end is connected for wet joint.
A kind of assembling method of prestressed assembly formula truss-like steel reinforced concrete structure system, it is characterized in that, including it is following
Step：
1）Prefabricated steel framed concrete beam segment, steel framed concrete section in the factory, steel reinforced concrete girder segment and steel
The beam section part of bone concrete beam and column node section need to reserve prestressed pore passage, steel reinforced concrete girder segment, steel in advance when making
Leave gusset plate and connected for wet joint in the end of bone concrete beam and column node section；
Wherein, prestressed pore passage is located at lower part into undulated arrangement in beam section at span centre, and top is located at bearing, begins
It is in tension position eventually；When making the truss-like reinforcing bar of steel framed concrete section, joist steel truss is passed through into column steel truss
Upper reserved hole, pouring concrete after positioning, reserves endpoint node plate and is connected for wet joint；
2）After prefabricated components transport to scene, prefabricated steel reinforced concrete girder segment, steel framed concrete section are lifted into
Position；Steel framed concrete section is first lifted, is connected at the gusset plate of its end by wet joint, the wet joint in end by connecting
The place's of connecing gusset plate is formed using high-strength bolt connection after-pouring concrete；
After the installation of steel framed concrete section fixes, then lift the steel reinforced concrete girder segment between node, girder segment
Particular number depending on the specific span of engineering structure system, equally, connected at the gusset plate of its end by wet joint, one layer
One layer of assembling；
3）After intensity needed for concrete at wet joint reaches, deformed bar is worn in prestressed pore passage reserved before, and
Fastened with anchorage anchor, form integral frame structure system, complete whole prestressed assembly formula truss-like steel reinforced concrete structure
The assembly of system.
The present invention is made of steel reinforced concrete girder segment, bean column node section, deformed bar, anchorage etc., its Basic Design
Theory is exactly：Steel bone joist frame should be able to undertake the various load actions occurred dead load and construction stage, deformed bar to
Secondary dead load and live load effect are born, and improves structural integrity and crack crotrol requirement.Steel reinforced concrete girder segment and beam
Column border node section is formed by prefabrication, and end reserves certain length gusset plate for connection, while reserves presstressed reinforcing steel duct；
At the construction field (site), by steel reinforced concrete girder segment and the lifting of bean column node section in place, termination junction gusset plate uses high-strength spiral shell
Tether and connect after-pouring concrete, form wet joint；After after joint, concrete reaches some strength, in prestressing force reserved before
Deformed bar is worn in duct, and is fastened with anchorage anchor, forms integral frame structure system.
Compared with prior art, the present invention its remarkable advantage is：It can make industrialization, the assembling journey of steel reinforced concrete structure
Degree greatly improves, and convenient construction, accelerates the construction speed and production efficiency of structure, save duration and project cost, pass through at the same time
Apply the scantling size that prestressing force reduces large-span structure, improve structural strength, improve structural integrity and crack resistance.Therefore
The structural system promoting the use in assembled arthitecutral structure, can produce good economic benefit.
