Description
Technical field
The utility model is prestressed steel pipe concrete frame double steel plate shear wall built in one kind, belongs to a kind of raising knot
The prestressing combination shear wall of structure anti-seismic performance and restorability.
Background technique
Shear wall plays to pass structural seismic performance as the lateral resistant member being most widely used in skyscraper
Important role.Steel pipe concrete frame shear wall is applied more at present, and as a kind of compound shear wall, it is given full play to
The resistance to compression of steel pipe concrete frame column and drawing-resistant function have good anti-seismic performance.Steel plate concrete combined shear wall simultaneously
The advantages of two kinds of materials of steel and concrete can be given full play to, improve conventional steel bar concrete ductility of sheer wall and energy dissipation capacity compared with
The disadvantage of difference has preferable application advantage in steel-concrete combined structure.Main three kinds of steel-concrete compound shear wall
Structure type, including embedded steel plate-concrete combined shear wall, unilateral steel plate combined shear wall and double steel plate shear wall.It is interior
In large deformation, concrete peeling easy to crack on the outside of steel plate is then difficult to about for embedding steel plate and unilateral steel plate combined shear wall
Beam steel plate bending deformation causes ductility of sheer wall and energy dissipation capacity to decline；Both form shear walls need live formwork, tie up simultaneously
It the processes such as wire-ties, construction is relatively difficult.The outside double steel plate of double steel plate concrete shear force wall can not only use rank
Section constraint concrete filled, improves concrete deformation ability, moreover it is possible to as concrete-pouring template, facilitate construction.
To further increase double steel plate compound shear wall performance, the utility model proposes built-in prestressed steel tube concretes
Native frame double steel plate shear wall.By the presstressed reinforcing steel in steel pipe concrete frame column, reduces and become under wall horizontal loads
Shape, to a certain degree restorability of the realization shear wall after geological process.
Summary of the invention
The purpose of this utility model is to provide a kind of raising structural seismic performances, realize restoring for structure to a certain degree
The steel pipe concrete frame double steel plate shear wall of performance, is mainly used for the shear wall knot of skyscraper or large complicated tier building
Structure or tube structure are deformed with reducing it in geological process flowering structure.
The utility model uses following technical scheme:
Built-in prestressed steel pipe concrete frame double steel plate shear wall is mainly answered by steel pipe concrete frame column (1), in advance
Power muscle (2), steel plate (3), vertical steel plate strip (4), peg (5) composition.Main feature are as follows: presstressed reinforcing steel (2) is placed in steel tube concrete
In native frame columns (1)；Steel pipe concrete frame column (1) is arranged in shear wall wallboard (6) two sides；Shear wall wallboard (6) uses outsourcing
Double steel plate.
Concrete strength used is not less than C50 in the steel pipe concrete frame column (1), to reduce loss of prestress；Institute
It is not less than Q345 with steel.
Size of the steel pipe concrete frame column (1) in thickness of wall body direction is greater than thickness of wall body, concrete filled steel tube side
The section of frame column is rectangle, and single-chamber body steel core concrete column can be used, Multicarity steel pipe concrete frame column can also be used.When adopting
When with rectangular section, steel pipe concrete frame column, depth-width ratio preferably between 1 and 2, to play steel pipe to the effect of restraint of concrete；
When steel pipe concrete frame column (1) depth-width ratio is greater than 2, using Multicarity steel pipe concrete frame column, or increases peg, puts more energy into
Rib construction measure.
The presstressed reinforcing steel (2) uses unbonded prestressing tendon, the configuration of presstressed reinforcing steel according to the cross-sectional sizes of shear wall and
The section steel ratio of steel pipe concrete frame column increases and decreases.Unbonded prestressing tendon uses underrelaxation steel strand wires or reinforcing bar, originally
When beginning stress is tensile strength 70%, stress relaxation test measures 1000h relaxation value less than 2.5% by GB/T 21839.
The shear wall encased steel plate (3) is by punching and then penetrates peg (5), steel plate (3) and steel pipe concrete frame
(1) it is welded by vertical steel plate (4) item；Peg length is greater than 4 times of peg diameters, and carries out spot welding and fix.
The top grid beam (7) and following grid beam or foundation beam (8) are reinforced beam, or are girder with rolled steel section en cased in concrete,
Section is rectangle, concrete cast in situs.
Prestressed steel pipe concrete frame double steel plate shear wall, the soap-free emulsion polymeization of use are pre- the utility model proposes built in
Stress plays a key effect for improving shear wall restorability.Under horizontal loads, when steel pipe concrete frame is cut
When power wall side tension one end is pressurized, unbonded prestressing tendon also cooperates.The elongation of tension side unbonded prestressing tendon, prevents
Shear wall continues to deform.When horizontal loading unloading or geological process weaken, the still tension soap-free emulsion polymeization of stretch section or elastoplasticity section
Presstressed reinforcing steel has tendencies toward shrinkage, to reduce shear wall deformation.The shear wall has the advantage that relative to common shear wall
(1) underrelaxation unbonded prestressing tendon is arranged in steel pipe concrete frame column, can not only improve the anti-of shear wall
Curved bearing capacity can also reduce steel pipe concrete frame shear wall residual deformation, realize function restorability；
(2) steel pipe concrete frame makes full use of the effect of restraint of concrete filled steel tube, is avoided that wall corner concrete mistake
Early conquassation, improves ductility of sheer wall；And the more loads of wall are shared, shear wall's thickness can be reduced to a certain extent,
Improve space utilization rate.Frame is stronger to the constraint of concrete wall simultaneously, and wall body slit is delayed to carry out；On the outside of shear wall
Steel plate in the case where peg is fixed can operative constraint concrete, improve shear wall shear behavior, while also serving as coagulation in the construction stage
Native construction formwork simplifies site construction technology.
Since shear wall is the core lateral resisting component of building structure, the shock resistance for improving shear wall, which just improves, finishes
The shock resistance of structure entirety.Built-in prestressed steel pipe concrete frame double steel plate shear wall is set, it is expected to be able to achieve building
Restorability energy；When building meets with violent earthquake, it can reduce its earthquake, prevent it from collapsing.
