Description
Technical field
The present invention relates to a kind of shear wall, cut more particularly, to a kind of overlapping for being based on half prefabricated ultra-tough armored concrete
Power wall.
Background technology
China is many earthquake countries, and bulk of property loss and life security are both from the failure of structure.Shear wall
It is a kind of good anti-seismic structure component, good antidetonation effect can be played in building structure particularly high-level structure.Example
As the A of Chinese patent CN 104018599 disclose a kind of shear wall structure, including side plate, side plate interior sides are provided with end shear wall,
End shear wall side is provided with shear wall between seam, is connected by connecting tube between shear wall between side plate, end shear wall and seam, and
Connecting tube one end extends in side plate outside, and one end that connecting tube is located on the outside of side plate is provided with pipe clamp, pipe clamp be used for by side plate,
Shear wall is fixed between end shear wall and seam, and shear wall outside is provided with reinforcing plate, shear wall between reinforcing plate and seam between seam
Between be fixedly connected by built-in screw, steel plate for sealing water, steel plate for sealing water more than one are provided with side plate, and steel plate for sealing water bottom is equal
Ribbed stiffener is transversely provided with, sealing gasket is connected between ribbed stiffener and steel plate for sealing water bottom.But, the corner of the shear wall structure exists
Earthquake is usually damaged when occurring by unrepairable, even if house does not collapse in earthquake, but but causes that structure cannot
Repair and produce huge property loss.
And for example the A of Chinese patent CN 103452235 disclose a kind of precast shear wall wallboard and shear wall and shear wall
Construction method.Precast shear wall wallboard, wallboard includes two panels；The inner surface of every piece of panel is provided with multiple grooves, every piece
Panel upper and lower ends face is provided with multiple slots；Extend transversely through muscle two ends and protrude two side elevations, and extend transversely through muscle through groove；
Upper and lower ends face is protruded longitudinally through muscle two ends, and slot is passed through longitudinally through muscle.Precast shear wall, the level side of shear wall
Multiple wallboards are respectively provided with to vertical direction.The construction method of precast shear wall, comprises the following steps：Live unwrapping wire, installation is faced
When fixed mount；Lifting wallboard in place, is connected with temporary fixing rack；Prefabricated upper strata floor is in place；Lay dark beam steel
And each additional muscle, lay pipeline；Pour high-flowing concrete；Into next layer of installation.Most current reinforced concrete
Native shear wall needs colligation at the scene, live formwork, and then disturbing concrete conserves shaping, the more difficult control of construction quality, due to
Assembling reinforcement and the quality of disturbing concrete and the qualification of construction worker and the degree of understanding to drawing are closely related, if
The mobility of workman is too big, and training degree not enough, drives plan, and construction material is unqualified, and the factor such as construction bad weather can all be led
The anti-seismic performance of the shearing wall member that cause finally gives is had a greatly reduced quality.If but all again with prefabricated mode itself and basic foundation
Combination force intensity it is unreliable, and high cost.
Furthermore, although normal concrete has compression strength higher but its tensile strength is smaller, in horizontal force action
Easy tensile failure, general reinforced concrete shear wall bearing horizontal loading, such as earthquake load and during high wind load, its side
The easy tensile failure of edge concrete, after producing direct tension cracking, its edge member angle effect region when pressure is born just more
It is easy to be pressurized and peels off.So, suffering certain horizontal force --- when earthquake or high wind are acted on, conventional steel bar concrete shear wall
Easily in edge corner failure damage.Although the destruction may not cause integrally-built failure, its edge concrete
Peel off, Bar Buckling can cause the difficulty for being difficult to repair, and what is brought therewith is probably integrally-built cannot reparation so that abandoning
Even need labor intensive material resources to remove to rebuild.
Although also having some preferable concrete of tension effect now, the cost of these concrete is often higher, if
It is in the building course of building, all using the concrete that these tension effects are good, often to cause that construction cost is too high.
The content of the invention
