Description
Technical field
The utility model relates to a kind of steel concrete cylindrical shell that is used in the highrise building, specially refers to a kind of cylindrical shell with dark support.
Background technology
Existing steel concrete cylindrical shell is made up of the shear wall of sealing, its loading characteristic is the space-load structure member, have than big-difference with the loading characteristic of plane primary structure member shear wall, but the relatively poor shortcoming of the ductility of shear wall still affects giving full play to of cylindrical shell anti-seismic performance to a certain extent.The arrangement of reinforcement of the shear wall of existing formation steel concrete cylindrical shell is the steel mesh reinforcement that two rows are made up of horizontal and vertical distribution reinforcement, deficiencies such as its rigidity, bearing capacity and ductility cause breakoff phenomenons such as shear failure and the concrete crushing of pressurized wall limb bottom to take place, thereby structural entity is destroyed; The areas of plasticity hinge of bottom is little at the bottom of the wall, and the energy dissipation ability is lower; The shear wall that constitutes cylindrical shell easily causes the bearing capacity of cylindrical shell to reduce fast after occurring shearing diagonal crack.
Invention people of the present utility model delays and limits seismic structural wall, earthquake resistant wall shear failure for reaching, and has proposed a kind of " built-in steel bar concrete supports and establishes dark half straight joint band edge frame seismic structural wall, earthquake resistant wall ", and obtains patent right on December 4th, 1998, and the patent No. is ZL97244563.3.The oblique concrete core bundle that forms by vertical muscle and corresponding stirrup that secretly is supported for of this patented technology, it and concrete shear force wall are commaterial, the co-operation between them is functional, has improved the shock resistance of shear wall significantly.
Summary of the invention
Technical problem to be solved in the utility model is the problem that significantly improves steel concrete cylindrical shell shock resistance, unborn subject matter has: the deficiencies such as shear wall rigidity, bearing capacity and ductility that (1) constitutes the steel concrete cylindrical shell cause the concrete crushing of pressurized wall limb bottom, thereby make structural deterioration.(2) areas of plasticity hinge of bottom is little at the bottom of the wall, and the energy dissipation ability is lower.(3) after the shear wall of formation cylindrical shell occurs shearing diagonal crack, easily cause the bearing capacity of cylindrical shell to reduce fast.In order to address the above problem, the utility model proposes a kind of reinforced concrete soil zone and secretly support cylindrical shell, it is a kind of space-load member that the reinforced concrete soil zone secretly supports cylindrical shell, has very big intensity and lateral resisting rigidity, in highrise building, can be used as main lateral resistant member, bear the horizontal earthquake action of the overwhelming majority.The loading characteristic of cylindrical shell is the space-load structure member, have than big-difference with the loading characteristic of plane primary structure member shear wall, such as secretly being supported on the similar effect that spiral hoop (regarding cylindrical shell as a perpendicular cantilever hollow unit) is from the bottom to top arranged in the cylindrical shell, the antitorque usefulness that transfers to can be arranged, and the dark support in the shear wall of plane just there is not this effect.
The technical scheme that the utility model adopted is referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the reinforced concrete soil zone that is provided secretly supports cylindrical shell, be the space tubular, its each face wall body is made of the dark concrete shear force wall plate that supports of band, wherein said band secretly supports the steel mesh reinforcement that configuration two rows are made up of horizontal and vertical distribution reinforcement respectively in the concrete shear force wall, between two row's distribution reinforcement nets, add and be furnished with the reinforcing bar bearing diagonal 10 that oblique tendon constitutes, reinforcing bar bearing diagonal 10 is used stirrup restraint, between steel mesh reinforcement, socket with socketing reinforcing bar, it is characterized in that: connect by shared frame columns 1 between the shear wall of every two sides, reinforcing bar bearing diagonal 10 is spatially spiral rising shape in cylindrical shell, one section reinforcing bar bearing diagonal 1-2 under the another side shear wall d that one section reinforcing bar bearing diagonal 3-4 directly over the shear wall b that one section reinforcing bar bearing diagonal 2-3 among the shear wall a is adjacent with shear wall a among the shear wall c of unitary space is adjacent with shear wall a among the shear wall e of unitary space is the tendon that is connected as one.
Described reinforced concrete soil zone secretly supports cylindrical shell, it is characterized in that: two the reinforcing bar bearing diagonals (10) that installing in every shear wall slab in the cylindrical shell are X-shaped, the dark supporting and space shape that rises in the shape of a spiral, the frame anchoring is stretched into from the middle part that upper ledge is set a roof beam in place in the upper end of bearing diagonal, and the frame anchoring is stretched into from the end of lower frame beam in its lower end.
The reinforced concrete soil zone secretly supports cylindrical shell and compares with the ordinary reinforced concrete cylindrical shell, can significantly improve the shock resistance of cylindrical shell, because the shear wall cylindrical shell is the core lateral resisting parts of building structure, improved the shock resistance of cylindrical shell, also just improved the shock resistance of structural entity, when building meets with violent earthquake, can alleviate its earthquake, prevent that it from collapsing.
