Description

Band perps precast shear wall structure in strong concrete precast frame
Technical field
The utility model relates to building structure technology field, particularly relates to band perps precast shear wall structure in a kind of strong concrete precast frame.
Background technology
Along with increase year by year that is high-rise, super highrise building, also more and more higher to the requirement of shear wall anti-seismic performance.Shear wall is the core lateral resisting parts in high building structure, and its anti-seismic performance plays conclusive effect for the safe and reliable of highrise building.When shear wall slab and framework in conjunction with time, usually make the shear wall slab system of band frame, in order to improve the antidetonation load-carrying properties of shear wall slab, those skilled in the art have studied various types of shear wall.As compound shear wall, its wallboard is made up of steel plate and concrete panel; Or wallboard adopts steel concrete, and frame adopts steel frame.Wherein adopt the system of solid shear wall slab fill frame, because wallboard is divided into low parapet, easily shear failure occurs, anti-seismic performance is poor.Also learn for this reason and propose band perps shear wall in steel frame, improve its anti-seismic performance, but existing ordinary concrete perps wallboard only has for C20 ~ C30, supporting capacity is lower, sometimes cannot meet the Seismic Design Requirements of high-level structure.And the system that more general perps shear wall slab and concrete frame combine rarely has report.
And for example Chinese patent CN202925717U discloses a kind of precast concrete framework and interior band perps precast concrete shear wall connected node, comprise band perps precast concrete shear wall and a Prefabricated superposed beam in two, described Prefabricated superposed beam to be arranged in two between band perps precast concrete shear wall, angle steel built-in fitting is preset with in described Prefabricated superposed beam, described angle steel built-in fitting comprises connector and is connected to upper head plate and the bottom plate at described connector two ends, and described upper head plate and bottom plate are all arranged with the flush with outer surface of described Prefabricated superposed beam; The top of described interior band perps precast concrete shear wall is preset with top shear key, bottom is preset with bottom shear key, the upper end plate that described top shear key comprises top junction plate and is connected with described top junction plate, described upper end plate is arranged on the upper surface of described interior band perps precast concrete shear wall, and described top junction plate part is pre-buried stretches described interior band perps precast concrete shear wall upper surface in described interior band perps precast concrete shear wall, outside part; The lower end plate that described bottom shear key comprises lower connecting plate and is connected with described lower connecting plate, described lower end plate is arranged on the soffit of described interior band perps precast concrete shear wall, and described lower connecting plate is embedded in described interior band perps precast concrete shear wall in advance; In described in the described bottom plate of described Prefabricated superposed beam and, the overhanging exposed portion of junction plate, described top of band perps precast concrete shear wall is connected and fixed, and described upper head plate and the described lower end plate of interior band perps precast concrete shear wall described in another of described Prefabricated superposed beam are connected and fixed.The shear wall connected node of this structure, because its Prefabricated superposed beam and interior band perps precast concrete shear wall all can be completely prefabricated, and the connected node between the upper and lower side of Prefabricated superposed beam with interior band perps precast concrete shear wall only need carry out simply welding at the scene and bolt is connected, reliable connection, construction is simple.But when at present this structure being used for shear wall structure, all adopt the concrete that strength grade is lower, anti-seismic performance is lower.
Therefore, those skilled in the art be devoted to study always a kind of anti-seismic performance better, strong concrete shear wall structure comparatively is flexibly set.
