Description
Technical field
It the utility model is related to architectural engineering assembling field, and in particular to a kind of assembled integral concrete frame structure.
Background technology
Assembling concrete frame structure can greatly improve construction ability and construction speed, save a large amount of labours, ensure
Build guality, and be advantageous to the requirement for reaching " environmental protection of four section one ", assembly concrete building is promoted in national increased force, is pushed away
There is good development prospect under the background of wide green building and green construction.
At present, known prefabrication and assembly construction frame structure both at home and abroad mainly has conventional prefabricated bean column node wet type to be linked and packed
Frame structure connects prestress assembly frame structure with node dry type.The prefabricated post of wet type connection framework is highly located at bean column node
Lower section, being combined between prefabricated post node section and prefabricated beam-ends by cast-in-place concrete, good integrity, energy consumption ability is excellent,
Structural behaviour is equal to cast-in-place structural, and the prefabricated integral frame structure Typical Representative has French generation structure system, Taiwan to moisten safe body
System.But cast-in-place concrete wet type connecting node, in-site installation efficiency is low, cost is high, and falsework dosage is big, and reinforcement installation is complicated
It is required that it is high, it is unfavorable for large scale integration production and construction.In addition, wet type assembling framework structural system must treat cast-in-place node shell of column
After concrete reaches some strength, the assembling construction of a upper floor could be carried out, installation effectiveness is not high enough, is unfavorable for shortening height
The layer assembled architecture index bed installation time.
The prestressing force assembling framework of node dry type connection, can preferably play precast concrete factorial praluction and scene
Installation effectiveness, and post-tensioned prestressing connection can provide good structure restorability, be easy to the reparation after earthquake disaster.It is existing
Prefabricated post-tensioned prestressing frame structure mainly has the PRESSS systems of the U.S.-Japan and the subassemblage concrete frame of Japan
System.Subassemblage concrete frame structure is that prefabricated post and precast beam is straight by penetrating post-tensioning, multistage, soap-free emulsion polymeization in beam
The prestressing force assembly concrete frame structure of line prestressing force and Tension Forming.The precast beam intercolumniation of PRESSS systems uses post-tensioning
Unbonded prestressing tendon and regular reinforcement carry out Hybrid connections, and presstressed reinforcing steel is passed through and reserved in whole beam longitudinal central axis line position
Presstressed reinforcing steel duct the both sides crossbeam of post is linked together, beam column seam filling mortar.Regular reinforcement is vertical up and down by beam
The reserved duct in muscle position passes through pillar, and carries out duct grouting in scene.Two kinds of structures use the related post section of whole beam
Point applies prestressing force, and the security of structure excessively relies on presstressed reinforcing steel, it is impossible to realizes the beam plasticity for leaving post side certain distance
Hinge transfer.In addition the presstressed reinforcing steel of subassemblage concrete structure needs lashing, tensioning etc. in the reserving hole channel of whole precast beam
Complicated construction technique, Structural Energy Dissipation are relatively weak；PRESSSS is difficult to give full play to tribute of its presstressed reinforcing steel for structural bearing capacity
Offer, its design theory also mismatches with China's specification current design methods.Also a kind of prestressed assembling framework structure of part
Dry type connecting node, on the step ends rest of its precast beam to the side bracket of prefabricated post, and in the prefabricated beam column in node area
Between arrange that horizontal arc intersects presstressed reinforcing steel and carries out local prestressing force crimping, the side that tension of prestressed tendon end is located at beam is kept away
Open the belly of upper and lower longitudinal reinforcement encryption scope.The dress of pure dry type connection of the joint form category without overlapping cast-in-place concrete surface layer
Matched with concrete frame structure, and with precast floor slab dry type splicing process, though its structural behaviour connects better than external similar bolt
Mode is connect, but structural integrity is weaker than cast-in-place concrete frame structure, therefore the joint form is mainly used in multilayer assembled
Concrete frame structure house.
