Abstract
The invention relates to a shear wall formed by embedding energy-dissipation bars between a frame and a wall with inbuilt multiple steel plates and a construction method. The shear wall with the inbuilt multiple steel plates comprises concrete-filled steel tube frame columns, precast concrete planks, high-damping energy-dissipation materials, connecting pieces and the middle steel plates. After the concrete-filled steel tube frame columns and the middle steel plates are manufactured, the precast concrete planks are manufactured at the same time; gaps are reserved between the precast concrete planks and the frame columns and between the precast concrete planks and the middle steel plates, and the gaps are filled with the high-damping materials. Under the action of an earthquake, the formed high-damping energy-dissipation bar frame firstly dissipates energy to protect the concrete planks and guarantees the integrity of the shear wall, so that the time before the concrete planks are damaged is prolonged, and seismic performance is improved. The precast concrete planks can be quickly replaced after the earthquake, so that the post-seismic restoring speed is increased, and the use function of houses can be restored as soon as possible. As the multiple steel plates are applied in a large-span space, the energy dissipation in blocks is achieved, and the materials can be fully utilized. Accordingly, good social benefits are achieved, and application prospects are broad.
Description
Technical field
The present invention relates between a kind of frame and built-in plurality of steel plates wall embedding power consumption band shear wall and the practice, belong to a kind of novel practical, energy consumption ability good and be applicable to the technical applications of high-level structure.
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 shear wall of the built-in plurality of steel plates 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, building span is increasing now, post is apart from also increase thereupon, the shear wall anti-seismic performance of the built-in plurality of steel plates of steel pipe concrete frame is good, bearing capacity is large, can be good at meeting the requirement of modern architecture.
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, post divides band power consumption mode apart from larger body of wall, 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 present invention is 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 plurality of steel plates wall.Phase solves concrete slab in the built-in plurality of steel plates shear wall of steel pipe concrete frame and easily crushes the problem that comes off and cause steel plate fully not consume energy.
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 plurality of steel plates wall, and this body of wall comprises steel pipe concrete frame post, precast concrete plank, high damping power consumption material, connector, middle steel plate; 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, has vertical straight joint between each steel plate, middle steel plate both sides outsourcing precast concrete plank; Precast concrete plank is connected with connector with middle steel plate; Headspace between precast concrete plank and steel pipe concrete frame post, fills with high damping power consumption material, forms embedding power consumption band shear wall between frame and built-in plurality of steel plates wall.
In described steel pipe concrete frame post, concrete is ordinary concrete or regeneration concrete.
Described middle steel plate and steel pipe concrete frame post connected mode are both sides fillet weld seam.
Between described precast concrete plank and steel pipe concrete frame post, all interspace in advance between precast concrete plank, middle steel plate, its horizontal width is 30mm to 60mm.
For reserved space, high damping power consumption material is filled between described precast concrete plank and steel pipe concrete frame post etc.
Compared with prior art, the present invention can obtain following beneficial effect.
High damping power consumption material is used for connecting precast concrete plank and frame columns, directly contact with frame columns, with precast concrete plank and the direct contact gear ratio of frame columns, high damping power consumption material can be under geological process pressurized first, form a vertical power consumption band, inner layer steel plate and frame columns form an entirety, prevent that precast concrete plank from destroying in earthquake initial compression, guarantee that flexing can not occur middle steel plate very soon, improve 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.
