Field.
Background technique
Shear wall is most common a kind of lateral resistant member in skyscraper, and conventional steel bar concrete shear wall is with its entirety
Property it is good, rigidity is big, lateral deformation is small, resist the advantages that wind load and medium and small grade earthquake effect are prominent and fire protecting performance is good, by
The favor of numerous engineers and technicians.But reinforced concrete shear wall rigidity is big, and biggish level is born under seismic force effects
Power, crack generation is more early, and the later period, ductility was small, energy dissipation capacity is poor based on failure by shear, is in brittle break, is not easily repaired after shake.
Steel plate-concrete combined shear wall improves the deficiency of reinforced concrete shear wall, steel plate and concrete composite to a certain extent
Shear wall, which refers to, is arranged steel plate in concrete two sides, by shear connector junction steel plate and concrete, makes the two as a whole
It works together, steel plate-concrete combined shear wall shear-carrying capacity with higher, good ductility and energy dissipation capacity.But it wants
Guarantee that steel plate-concrete combined shear wall light plate is cut buckling failure, guarantee that steel plate works together as a whole with concrete,
Shear connector or the intensive ribbed stiffener of setting need to be covered on the steel plate, cause the design, manufacture and construction of shear wall complicated, cost
Increase；It is simultaneously processing, production and the installation accuracy requirement for guaranteeing steel plate, " steel plate shear force wall technical regulation " (JGJ/T380-
2015) minimum thickness of unilateral steel plate is not preferably less than 10mm, and thickness of wall body in clear stipulaties steel plate-concrete combined shear wall
It is not preferably less than 250mm, limits application of the steel plate-concrete combined shear wall in multi- story and high- rise building.In addition, to prevent from pouring
It builds Concrete light plate and the mould phenomenon that rises occurs, a large amount of supports need to be set in steel plate two sides, increase the complexity of construction.It closes
Shape of the mouth as one speaks profiled sheet compound shear wall, which efficiently solves, needs setting to socket key in double steel plate combined concrete shear wall, construction is complicated
The problem of, using the geometrical property of closed-section steel deck itself, when casting concrete, closed-section steel deck has biggish
Out of plane stiffness is able to satisfy the demand of casting concrete, and after concrete hardening, closed-section steel deck is embedded in concrete
Portion can effectively anchor profiled sheet, avoid the problem of setting shear connector is needed in common double steel plate shear wall, while silent
Type profiled sheet thickness can be adjusted accordingly according to bearing capacity and anti-side rigidity demand, compensate for steel in double steel plate shear wall
The excessive problem of plate thickness, it is more economical, reasonable.Since closed type floor is inside wall, and steel plate is relatively thin, connection compared with
For difficulty, thus the connection of closed-section steel deck compound shear wall medium-pressure type steel plate be limit its engineer application critical issue it
One.

Two opposed closed-section steel decks, and first edge stiffener, the second side is respectively arranged in two sides up and down between stiffener
Edge stiffener is connected with closed-section steel deck three surrounds a hollow building enclosure, on closed-section steel deck inner surface
It is respectively provided with a plurality of rib of slab along longitudinal direction, a plurality of rib of slab interval is arranged, welding short steel rod at the top of the rib of slab of closed-section steel deck, and
One end of the bar dowel is stretched out at the docking of two closed-section steel decks of the same side, guarantees that the internal force of top floor effectively passes
Lower part floor is passed, node connecting plate is equipped at two closed-section steel deck docking of the same side, is set in hollow building enclosure
There is the shear connector being connected with first edge stiffener and second edge stiffener, has been poured in hollow building enclosure mixed
Solidifying soil.
The beneficial effect of the utility model compared with prior art is: closed-section steel deck combined concrete shear wall is by two
Side closed-section steel deck, concrete and edge constraint component composition, the fin of closure are divided into profiled sheet multiple vertical
Strip makes general steel plate be changed into multiple strips by being cut in integral planar and individually cut.Preliminary analysis shows: closed type die mould
Steel plate concrete combined shear wall utilizes the compound action of profiled sheet and concrete, can give full play to two kinds of materials itself is excellent
Gesture shows higher bearing capacity, good energy dissipation capacity and deformability under lateral force and longitudinal force collective effect.It closes
Degree of lip-rounding fin is embedded in inside concrete, can effectively anchor profiled sheet, is it is not necessary that shear connector is arranged in hollow building enclosure
