Description
Technical field
The present invention relates to house architectural structure fields, and in particular to a kind of armor formula steel plate concrete shear wall.
Background technology
Steel plate shear wall structure is that the one kind for developing and growing up on thin webbed girder theoretical research foundation is embedded with frame
Steel plate is the novel Lateral Resistant System of basic structural unit.Steel plate shear force wall has following good superior function：1. initial side
Big to rigidity, Hysteresis Behavior is stablized, and energy dissipation capability is strong, and ductility is big, and the deformability resisted under cyclic load is good.2. pass through
Improve its rigidity and ductility, realize the matching with outline border frame material, ductility, rigidity, can realize the dual purpose set up defences.3. steel
The setting of steel plate is embedded in board wall can alleviate the Ductility Requirement in concrete frame joint area, reduce the rigid joint under severe earthquake action
Earthquake reaction, while joint structure can be simplified, can realize structures with semi-rigid joints.It is relatively thin that 4. steel plate wall embeds steel plate, ratio of height to thickness
Up to 250~500, the effective usable floor area in house can be increased.
Due in conventional steel plates shear wall, under horizontal loads, always with larger after non-thin plate buckling of putting more energy into
Buckling sound, while generate larger out-of-plane deformation.This means that during larger wind load or geological process, there is noise production
It is raw, influence the comfortable for living of building.Conventional steel plates shear wall relies primarily on, and the pulling force field formed after buckling is come the level of resisting
Power, the pulling force field being anchored on frame can generate extra bending moment to side column, side bar, and increase pillar stablizes burden.It is meanwhile thin
Steel plate shear force wall buckling under smaller shearing action, hysteretic loop have significant pinch, reduce the energy dissipation capacity of steel plate shear force wall.
By to combined steel plate shearing force wall the study found that it has the following problems:1. conventional combination steel plate shear force wall
Reinforced concrete cover plate and embedded wallboard are completely be bonded, participate in having resisted a part of horizontal force when constraining wallboard, but due to
Both steel plate and concrete slab deformation are filled out under large deformation, reinforced concrete cover plate easily occurs and bears larger tensile stress
Situation squeezes outside the face of steel plate, concrete is caused constantly to be detached from steel plate in addition, loses the interior of concrete slab protection and fills out steel plate work
With later stage performance is still degenerated for sheet metal wall.2. edge concrete cover will occur to squeeze to destroy.3. the destruction drop of concrete
The low long-term behaviour and durability of structure.Above-mentioned reason causes cover board to exit work in advance, it is impossible to the thin steel of lasting constraint
The buckling of plate, it is thin steel plate shear wall that combined steel plate wall is caused, which to be degenerated, and projected life is shorter.
Chinese invention patent CN 105692817 A, it is entitled:" a kind of combined steel plate shearing force wall structure ", discloses
A kind of steel plate and concrete composite combined structure type steel plate shear wall structure.The shear wall structure although solve in fill out steel plate with
Both concrete slabs deformation problem, avoiding concrete slab broken stripping problem from steel plate causes concrete to move back in advance
Go out work, eventually lead to combined steel plate wall and degenerate for thin steel plate shear wall problem.But it has the disadvantage that:1. concrete slab is,
What the frictional force generated by the inner surface of nut or elastic material and concrete slab mounting hole was fixed.This connection side
Formula intensity is insufficient, inadequate to middle steel plate restraining force, it is impossible to effectively inhibit the bending deformation of steel plate.2. since armored concrete adds
The presence of work and steel plate mismachining tolerance, it is small general that the more split bolt of number is disposably inserted into possibility in concrete slab simultaneously
Rate event needs scene to carry out debugging allotment to concrete slab upper installing hole, takes time and effort.3. reinforced concrete cover plate volume
Greatly, transport installation difficulty is big, seriously constrains the application range of this kind of shear wall.4. reinforced concrete cover plate volume is big, installation
Kong Duo belonged to positioning between reinforced concrete cover plate and steel plate, when middle steel plate deforms, the elastic washer of installation is not
Foot has offset steel plate deformed, and the right meeting stress of entire concrete cover times, which crushes, to come off.
Therefore, couple reliably with steel plate there is an urgent need to a kind of concrete cover at present, installation and transportation are convenient, concrete cover
Stripping will not be crushed in advance, what concrete slab can be relatively moved with steel plate, the wide armor formula steel of industrialization prospect
Board concrete shear wall.
Invention content
For overcome the deficiencies in the prior art, the present invention seeks to：A kind of armor formula steel plate concrete shear wall is provided.It should
Steel plate concrete shear wall and the difference of conventional steel plates concrete shear force wall are：1. concrete cover is in being fixed by screws in

The force modes of system combined steel plate shearing force wall and modified combined steel plate shearing force wall, making can between steel plate and armoured concrete slab
The relative displacement along surface of steel plate occurs, reduces the tensile stress of armoured concrete slab.
（5）Front and rear two block concretes cover board is pressed on intermediate steel plate by screw assembly.Steel plate and armoured concrete slab
It will not be detached outside generating surface, armoured concrete slab can effectively constrain the out-of-plane deformation of steel plate shear wall structure so that steel plate is cut
The hysteresis loop of power wall construction is more smooth, Hysteresis Behavior is more stablized, and so as to keep continuing energy dissipation capacity, improves concrete slab
Long-term behaviour and durability.
（6）Screw assembly is subjected only to pulling force, while is not involved in shearing resistance, avoids the welding sequence of conventional bolt and steel plate edge thick
Direction stress is spent, reduces the welding residual stress of steel plate.
（7）Reinforced concrete cover plate constrains steel plate out-of-plane deformation, changes the stress performance of steel plate, makes sheet metal pulling force
The shearing mechanism of steel plate is converted to effect.So as to reduce the noise of wallboard, the hysteresis of steel plate shear force wall is significantly improved
Performance.
（8）Combined steel plate shearing force wall has the advantages that conventional steel plates shear wall, relies primarily on steel plate and consumes energy, compares
In concrete shear force wall, there is preferable anti-seismic performance.
（9）Due to the presence of reinforced concrete cover plate, the effects that fire prevention, heat preservation, sound insulation can be played, can reduce the later stage
Workload reduces cost.
