Abstract

The utility model discloses a high damping concrete composite nucleus shell for strengthening mixed hidden support, which comprises four shear walls sounding into a shell, wherein two rows of steel-bar nets formed by steel bars distributed longitudinally and laterally are arranged in shear wall plates, and adjacent two shear walls are connected by a frame post. The utility model is characterized in that a pair of positive cross H-type steel is arranged in the frame post; each shear wall is both composed of a shape steel concrete frame post, a shear wall plate, a steel-plate connecting beam packed by high damping concrete and a high damping concrete middle post; a steel-plate hidden support is arranged between the two rows of steel-bar nets, and a hooping is arranged along the total lengthof the steel-plate hidden support; and a pair of angle steel is arranged in the high damping concrete middle post. Compared with the existing shells, the utility model has the advantages of large initial rigidity, high bearing ability, good tensibility and good entire quake-proof power-wasting performance.

Description

Strengthen mixing the dark high damping concrete combination core shell that supports
Technical field
The utility model relates to field of civil engineering, specifically is used as a kind of high damping concrete combined barrel system of strengthening mixing dark support of main lateral resistant member in the highrise building.
Background technology
The key of antidetonation mitigation is to strengthen the shock resistance of building.In high-level structure, the core tube is main lateral resistant member, is bearing the horizontal seismic force of structural entity 80% approximately.The good cylindrical shell of development anti-seismic performance is the core technology of high-level structure seismic design.Existing steel concrete cylindrical shell generally comprises the quadruple shear wall that surrounds cylindrical shell, in shear wall slab, dispose the two placing of reinforcement nets of forming by horizontal and vertical distribution reinforcement, the deficiency of its rigidity, bearing capacity and ductility easily causes shear failure and the concrete crushing of pressurized wall limb bottom, thereby structural entity is destroyed; , and the areas of plasticity hinge of bottom is little at the bottom of the wall, and the energy dissipation ability is lower.In the existing scheme of improving the concrete barrel anti-seismic performance, have in the shear wall of steel concrete cylindrical shell, to add the dark technology that supports of reinforcing bar.The problem of its existence is: concrete tension, the pressure energy power deficiency of oblique dark supporting core part.In the existing scheme of improving the concrete barrel anti-seismic performance, in the shear wall of steel concrete cylindrical shell, add the technology that shaped steel supports in addition.The problem of its existence is: shear wall is difficult to form reliable the connection between supporting with shaped steel is dark, causes structural system can not give full play to the antidetonation advantage in big earthquake centre.In the existing scheme of improving the concrete barrel anti-seismic performance, in the shear wall of steel concrete cylindrical shell, add the technology that steel plate supports in addition.The problem of its existence is: the steel plate stress performance than other shaped steel a little less than, tension, pressure energy power deficiency, supporting base end portion is prone to local buckling.
The utility model content
The purpose of this utility model is to provide a kind of reinforcement that significantly improves steel concrete cylindrical shell shock resistance to mix the dark high damping concrete combination core shell that supports.
The technical solution adopted in the utility model is: comprise the quadruple shear wall that surrounds cylindrical shell, in shear wall slab, dispose the two placing of reinforcement nets of forming by horizontal and vertical distribution reinforcement, connect by frame columns between the two adjacent surfaces shear wall, it is characterized in that, in frame columns, be provided with a pair of H font steel that forward intersects, every shear wall is by the steel reinforced concrete frame columns, shear wall slab and form by the steel plate coupling beam and the high damping concrete center pillar of high damping concrete parcel, between two placing of reinforcement nets, add and be furnished with steel plate and secretly support, and, in center pillar, be provided with a pair of angle steel along the dark total length configuration stirrup that supports.
The dark support of described steel plate is X-shaped, is fixed with two pairs of X-shapeds and secretly supports in story height.
The two pairs of X-shapeds are dark support respectively with frame columns in H font steel and the L angle steel in the center pillar weld mutually, steel plate in the coupling beam welds mutually with angle steel in the center pillar, H font steel in the frame columns, the steel plate in the shear wall slab secretly support, and angle steel in the center pillar and the steel plate in the coupling beam are combined to form steel truss.
Angle steel in the described center pillar is a pair of L type angle steel.
Cylindrical shell of the present utility model is bigger than the initial stiffness of existing cylindrical shell, supporting capacity is high, ductility good, can significantly improve the shock resistance of cylindrical shell, because the shear wall cylindrical shell is the core lateral resisting parts of high-level structure, has improved the shock resistance of cylindrical shell, has also just improved the shock resistance of structural entity.
