1. the column cross-section size of cast-in-situ steel reinforced concrete heterotypic column racking configuration is narrower, because frame column vertical reinforcement and Vierendeel girder horizontal reinforcement cross at the node place, causes reinforcing bar intensive, and concrete is difficult to vibration compacting, causes the node shock resistance to descend;
2. under action of horizontal seismic, Structure Beam-column node place produces the even numbers moment of flexure, and concrete is drawn, the alternating action of compressive stress, ftractures easily, reduces the rigidity of structure, and is unfavorable to antidetonation;
3. the heterotypic column racking configuration column cross-section size is narrower, and the cast-in-situ concrete difficulty of construction is big, and is long in time limit, and efficient is low, is unfavorable for the realization of housing industrialization.
From the analysis of above three aspects,, improving shock resistance, be convenient to construction, improving aspects such as industrialized level and be still waiting further to promote and improve though the cast-in-situ steel reinforced concrete heterotypic column racking configuration has promoted the service property (quality) of dwelling house.
Three. summary of the invention:
1. purpose: the present invention intends overcoming the deficiency of prior art, node place at the flooring absolute altitude is provided with the conversion cushion block, provide the prefabricated hetermorphiscal column in multiple cross section to cooperate integrated prestress assembling slab column system to use, with this structural system as multi-storey building, satisfying under the prerequisite of not revealing post between housing types, improving its shock resistance and industrialized level.
2. technical scheme:
The prefabricated special-shape column that the design relates to is by profiled-cross-section post 1, conversion cushion block 2 is formed, cooperate presstressed reinforcing steel 3, side bar 4, common cushion block 5, floor 6 is formed special-shape column integrated prestress assembling slab column systems, it is characterized in that at the node place of the flooring absolute altitude of the joint of profiled-cross-section post 1, side bar 4, floor 6 a conversion cushion block 2 being set.After the reinforcing bar binding of profiled-cross-section post 1 and conversion cushion block 2 was in place, concreting made the two be combined into an integral prefabricated member, and prefabricated special-shape column completes.Adopt presstressed reinforcing steel 3 in Vierendeel girder, presstressed reinforcing steel 3 penetrates the preformed hole on conversion cushion block 2 and the common cushion block 5, and framework is applied prestressing force, and that prefabricated special-shape column can adopt is square, T shape, L shaped or circular cross-section.By the use of conversion cushion block, same hetermorphiscal column can be selected the different cross section shape at different floors.
The job practices of this prefabricated special-shape column is:
(1) according to selected prefabricated post section form, processing template, the reinforcing bar of the reinforcing bar of colligation profiled-cross-section post and conversion cushion block;
(2) build profiled-cross-section post and the concrete of changing cushion block simultaneously, make the two form an integral prefabricated member, prefabricated special-shape column completes.
3. adopt the integrated prestress assembling slab column system of prefabricated special-shape column to compare following advantage with the cast-in-situ steel reinforced concrete heterotypic column racking configuration:
(1) adopt presstressed reinforcing steel to replace reinforcing bar in the Vierendeel girder, arrangement of reinforcement quantity is few, and the node concrete is easy to vibration compacting;
(2) since the cross section of conversion cushion block greater than the cross section of special-shape column, the reinforcing bar by node can obtain excellent protection, node concrete reliability is higher;
(3) under action of horizontal seismic, although integrated prestress assembling slab column system still produces the even numbers moment of flexure at the bean column node place, because prestressed existence, its node concrete is in pressure constant state, does not ftracture, and the recovery capability of structural rigidity is strong;
(4) prefabricated special-shape column is batch production production, the efficiency of construction height, and component quality is good, the requirement of the housing industrialization that is content with very little;
4. adopt the integrated prestress assembling slab column system of prefabricated special-shape column to compare following advantage with existing integrated prestress assembling slab column system:
(1) the frame column cross section of existing integrated prestress assembling slab column system can only be the square-section, reveal post between housing types, influence the use in room, and prefabricated special-shape column integrated prestress assembling slab column system can be selected suitable column section shape according to the building needs, do not reveal post between housing types, easy to use;
(2) the conversion cushion block can make same pillar select different cross sectional shapes at different floors, for architectural design is allowed some leeway.
