Abstract
The invention relates to a shear wall with energy-consuming strips embedded between a border and built-in steel plates and steel braces, and a making method. A wall body comprises steel tube concrete border columns, precast concrete plates, high-damping energy-consuming materials, connectors, intermediate steel plates, and reinforcing steel braces. The steel tube concrete border columns, the intermediate steel plates and crossed reinforcing steel braces are made, and meanwhile, the precast concrete plates are made; gaps are reserved between the precast concrete plates and the border columns and are filled with the high-damping energy-consuming materials. The formed energy-consuming strip border firstly consumes energy to protect the concrete plates, ensures the integrity of the shear wall, prolongs the breakage time of the concrete plates, and improves the anti-seismic property under the action of earthquake; the reinforcing steel braces bear skew force, and improves the buckling resistant capacity; the precast concrete plates can be quickly replaced after earthquake, so that the repair rate of post-earthquake is improved, and houses can quickly restore the use functions; the shear wall has good social benefits and broad application prospects.
Description
Technical field
The present invention relates to embedding power consumption band shear wall and the practice between a kind of frame and built-in steel plate, steel support, belong to a kind of novel practical, energy consumption ability well and be applicable to high-level structure technical applications.
Background technology
Earthquake is one of natural calamity of the serious harm mankind, and it has the features such as sudden, regional and destructive.China is in the multiple phase of earthquake in recent years, and 17 secondary earthquake disasters have only just occurred for 2006, wherein Wenchuan earthquake, and the economic loss causing just reaches 6,451 hundred million yuan, and dead and wounded number reaches more than 10 ten thousand.At present, because urban land growing tension and social demand become more diverse, height and the span of building constantly increase, and build becomes increasingly complex, and seismic analysis of structures and design difficulty constantly increase.China is many built and be positioned at strong earthquake area at the highrise building of building, and faces serious earthquake disaster and threatens.Existing reinforced concrete shear wall ductility under geological process is poor, and brittle fracture easily occurs, and this is very unfavorable to integrally-built anti-seismic performance.
Shear wall is the core lateral resisting parts in high building structure, the good shear wall of development anti-seismic performance is one of key technology of Seismic Design of Building, and shear wall also requires larger elasticity initial stiffness, large deformation ability and the good feature such as plastic property, stable hysteretic characteristic.The appearance of external wrapping concrete compound shear wall has not only well met above-mentioned requirements, and can effectively overcome reinforced concrete shear wall from the shortcoming such as great, bight concrete is easy to crack, frangible, strengthen in addition the side direction bending rigidity of shear wall, become a kind of high-rise Lateral Resistant System very with development prospect.The combination construction being combined by steel work and concrete structure, owing to having brought into play bi-material advantage separately, has become one of primary structure form of high-rise and super highrise building at present.Along with highrise building is more and more, the anti-seismic performance research of novel shear wall is more and more with application, and steel plate shear force wall is exactly wherein a kind of.
Research to steel plate shear force wall shows: steel plate shear force wall has good ductility; Analyze the anti-seismic performance of steel plate external wrapping concrete compound shear wall, shown that it has good energy dissipation ability; Add Seismic Bearing Capacity and ductility that steel pipe concrete frame can obviously improve shear wall.The built-in steel plate shear force wall of steel pipe concrete frame is a kind of novel steel plate combined shear wall, its feature is the advantage such as strong concrete filled steel tube anti-pressure ability, ductility is good and steel plate combined shear wall lateral deformation stiffness is large etc. that advantage has been carried out reasonable combination, anti-seismic performance is good, and bearing capacity is large.
But above-mentioned research is less to the research of steel plate outsourcing precast concrete plank, concrete slab is easily squeezed to destroy and comes off, and concrete can not be given full play to its effect, and is unfavorable for repairing fast after shake.Therefore study the method for attachment of concrete slab and concrete-filled steel tubular frame, to giving full play to the effect of all parts, the reparation speed improving after shake has great significance, and has important social value and economic benefit.
Summary of the invention
The object of the invention be to provide a kind of have simple structure, construction rapidly, anti-seismic performance is good, consume energy band shear wall and the practice of embedding between the frame of the advantage such as ductility and precast concrete plank compressive property that can make full use of steel plate and built-in steel plate, steel support.Easily crush to come off to concrete slab in the built-in steel plate shear force wall of solution steel pipe concrete frame and cause the abundant energy consumption issues of steel plate.
For achieving the above object, the technical solution used in the present invention is embedding power consumption band shear wall between frame and built-in steel plate, steel support, and this body of wall comprises steel pipe concrete frame post, precast concrete plank, high damping power consumption material, connector, middle steel plate, reinforcing bar diagonal brace composition; Described steel pipe concrete frame post is common steel tube concrete column or steel tube regeneration concrete column; Body of wall is welded by middle steel plate and steel pipe concrete frame post, a reinforcing bar diagonal brace of the each welding in middle steel plate two sides, reinforcing bar diagonal brace arranged crosswise; Middle steel plate both sides outsourcing precast concrete plank, the reserved groove of arranging reinforcing bar diagonal brace of a side on precast concrete plank; Precast concrete plank is connected with connector with middle steel plate; Precast concrete plank and steel pipe concrete frame intercolumniation headspace, fill with high damping power consumption material, forms embedding power consumption band shear wall between frame and built-in steel plate-steel support.
In described steel pipe concrete frame post, concrete is ordinary concrete or regeneration concrete.
The connected mode of described middle steel plate and steel pipe concrete frame post, middle steel plate and side reinforcing bar diagonal brace is both sides fillet weld seam.
Between described precast concrete plank and steel pipe concrete frame post, interspace in advance, its horizontal width is 30mm to 60mm.
Described precast concrete plank is reserved and the corresponding groove of reinforcing bar diagonal brace, ensures that reinforcing bar diagonal brace can embed in precast concrete plank.
Compared with prior art, the present invention has following beneficial effect.
High damping power consumption material is used for connecting concrete slab and frame columns, directly contact with frame columns, with precast concrete plank and the direct contact gear ratio of frame columns, the energy dissipating band frame that high damping power consumption material forms can be under geological process pressurized first, earthquake energy; Inner layer steel plate and frame columns form an entirety, prevent that precast concrete plank from destroying in earthquake initial compression, and the application of reinforcing bar diagonal brace ensures that flexing can not occur middle steel plate very soon, improves the bearing capacity of body of wall simultaneously, improves the energy dissipation ability of shear wall; The application of precast concrete plank, has saved the construction period, is conducive to the quick reparation after shake, has great social benefit.
