Abstract
The invention provides a reinforced concrete-filled steel tube frame steel plate composite shear wall with built-in concealed bracings and a manufacturing method, and relates to the field of construction. Cast-in-place reinforced concrete, a steel plate shear wall and concrete-filled steel tubes are combined together to form the composite shear wall. The two sides of a single steel plate are respectively provided with one inclined mild steel plate concealed bracing, and the steel plate concealed bracings on the two sides are intersected and of an X shape. Reinforcement fabrics formed by transversely-distributed reinforcements and longitudinally-distributed reinforcements are arranged outside the two concealed bracings and connected through tie reinforcements. Spiral stirrups are arranged in concrete-filled steel tube columns at the two ends of the shear wall, and therefore the bottoms of the concrete-filled steel tube columns are prevented from being damaged in advance. Compared with an existing shear wall, the reinforced concrete-filled steel tube frame steel plate composite shear wall with the built-in concealed bracings is larger in initial stiffness, higher in bearing capacity, and slower in attenuation of bearing capacity and stiffness, the whole anti-seismic and energy dissipation performance is good, the anti-seismic performance in the later period of the wall is relatively stable, and the whole working performance of the composite wall is good.
Description
Technical field
The present invention relates to a kind of steel core concrete column frame steel plate combined shear wall, particularly the built-in dark support combinations shear wall of reinforced steel pipe concrete frame steel plate and the practice.
Background technology
Along with the development of Chinese national economy and the continuous expansion of infrastructure scale, particularly superelevation greatly across and the form of structure of other specific (special) requirements more and more general, structure is had higher requirement, and new material, continuing to bring out as meeting these requirements of new technology have been created condition.Steel-concrete combined structure takes full advantage of steel and concrete material property separately, has that bearing capacity is high, rigidity is large, anti-seismic performance and power performance is good, sectional dimension of members is little, the advantage such as fast of constructing.Compare with concrete structure, can reduce sectional dimension of members, alleviate dead load, reduce geological process, increase effective usage space, reduce the advantages such as ductility of foundation cost, convenient construction, raising structure; Compare with steel work, have that steel using amount is few, an advantage such as rigidity is large, globality and good stability, apyrous and durability height.
Steel plate shear wall structure is a kind of novel lateral resisting structure system that 20 century 70s grow up.Experimental study and engineering are applied and are shown, steel plate shear force wall has a lot of excellent characteristics such as larger elasticity initial stiffness, large deformation ability and good plastic property, stable hysteretic characteristic etc.At present become a kind of high-rise Lateral Resistant System very with development prospect, be particularly useful for high intensity Zone building.
Combined steel plate wall is to fix or cast-in-situ steel reinforced concrete in steel plate one or both sides, and 2 kinds of materials are by shearing resistance peg preset on embedded steel plate or be bolted composition one.Two kinds of different structural forms of combined steel plate wall make it have different mechanical characteristics.The steel plate external wrapping concrete wallboard of combined steel plate wall, can play the effects such as fire prevention, insulation, sound insulation, has reduced follow-up work amount, has reduced construction costs.The cylindrical shell that shear wall and shear wall form is the core of high-rise construction earthquake resistance, the anti-seismic performance of shear wall structure has very important effect for highrise building safe and reliable, and the anti-seismic performance requirement of high-rise and super highrise building cylindrical shell that shear wall and shear wall are formed is also more and more higher.
Summary of the invention
Technical problem to be solved by this invention is: improve compound shear wall bearing capacity, ductility and energy dissipation ability.The advantage of concrete filled steel tube and steel plate shear force wall is combined, take i shaped cross section external wrapping concrete to solve the problem of the outer unstability of steel tube concrete core pillar plane simultaneously.
The technical solution used in the present invention is:
The built-in dark support combinations shear wall of reinforced steel pipe concrete frame steel plate, is characterized in that: its body of wall periphery is to be enclosed and formed by steel concrete 9; Body of wall internal configurations steel plate 2 and dark support 7; Dark support 7 is arranged in steel plate both sides; Steel plate two ends are respectively equipped with the Concrete-Filled Square Steel Tube frame columns 1 that steel plate encloses formation; Steel plate secretly supports outside and is provided with the steel mesh reinforcement being comprised of longitudinal distribution reinforcement 5 and transversely distributed steelbar 4, and shear wall side bar is section steel beam 13; On steel plate 2, be provided with the hole of passing for steel tie 10; Steel pipe concrete frame post 1 outside, two ends is provided with outer outstanding peg 6; Two steel pipe concrete frame post 1 inside of steel plate 2 end welding are provided with spiral stirrup 3;
Dark supporting steel plate angle of inclination is between 45 ° to 60 °;
The dark 7 use mild steel plates that support are made;
Spiral stirrup 3 in steel pipe concrete frame post 1 exceeds the upper plane in basis.
The preparation method of built-in steel plate and dark supporting steel pipe concrete column combination shear wall, the method is carried out in the following order:
1) make the steel pipe column of steel pipe concrete frame post 1, on steel pipe column, weld stud 6 and the steel plate bar 8 being vertically connected with steel mesh reinforcement, arrange spiral stirrup 3 in steel pipe;
2) configure dark supporting steel plate 7, dark supporting steel plate 7 comprises two blocks of mild steel steel plates, is arranged in steel plate 2 both sides, intersects and is X-shaped layout, oblique through steel pipe concrete frame post 1, the place welding contacting with steel pipe concrete frame post 1;
3) arrange the distribution reinforcement net that vertical reinforcement 5 that the transverse reinforcement 4 arranged by horizontal direction and vertical direction are arranged forms, be arranged in the outside of dark support 7, and with tension rib 10 drawknots;
