Pit in；The Weak link key for externally protruding out in two wall element surfaces is equipped between lower layer's wall element and upper wall unit.
Seismic shear wall of the present invention compared with prior art, has following remarkable advantage and advantageous effect：
Firstly, since upper wall unit and two sections of columns of both sides are not the overall structures integrally poured into a mould and each other
There are the gaps of shaking, and between upper wall unit and lower layer's wall element are cooperated by convex block and pit, this
Sample, under the horizontal force action of earthquake, the trend of upper wall unit double swerve can be lifted by the slope surface at left and right sides of pit,
The kinetic energy for changing double swerve is gravitional force, and due to the huge dead weight of wall, kinetic energy can be cleared up rapidly so that upper wall
The amplitude that unit is lifted displacement is small, and upper wall will fall reset after rise after kinetic energy resolution, this it is avoided that two heel posts and
Building overall structure causes larger impact damage；Moreover, also due to the huge dead weight of upper wall, will produce prodigious
Frictional force so that during double swerve is lifted and fallen after rise, kinetic energy and gravitional force constantly friction are converted into thermal energy and dissipate wall
Fall；That is, seismic energy is effectively relieved, converts by above structure, utmostly reduces earthquake and building is held

It resists without being destroyed；When earthquake intensity is slightly larger, when horizontal force is slightly larger, can the weaker vertical connecting key of preferential destruction, and by
Baseplane between two lifting faces provides the short space that translation is moved for convex block, so that convex block is flat at the bottom of pit
The horizontal sliding of slight amplitude is done in face, and the side of convex block is not contacted with the lifting face of pit, and wall is not lifted, and is only existed
Earthquake intensity is big, when horizontal force is also larger, after the side of convex block reaches the lifting face of pit, can just be lifted, that is,
It says, is not the lifting for destroying even metope that each secondary earthquake can all cause vertical Weak link key, this is just provided with for micro-
The triple protection of small intensity, slightly larger intensity and larger intensity seismic force effectively prevent anti-shock mechanism excessively sensitive, any primary micro-
Small earthquake results in the drawbacks of destruction of Weak link key or metope lifting；Moreover although externally protruding out in the presence of the Weak link key of metope,
Need to carry out post-processing such as mortar floating to metope can just to use, increase process, but above-mentioned drawback with there are the advantages of
Compared to being completely negligible, the Weak link key of evagination metope does big benefit and is to be destroyed and metope is fallen after rise in earthquake
After reset, due to being located on the outside of metope, therefore can be convenient, flexible re-replace new Weak link key, repair is simple and convenient
Fast.

Side is two lifting face of left and right；The two sides of trapezoidal convex block are parallel with the two sides of trapezoidal pit respectively；Such shape or so
Symmetrically, stress equalization is stablized, and when wall lifting, the lifting face of convex block side and pit is mutually parallel, and contact area is big, friction
Power is big, and lifting process is also more stablized, good to the transfer of seismic energy, changing effect.
Weak link bond structure is preferably：Two metopes of upper wall unit are all provided with there are one upper installation steel plate, are pacified on two
Cartridge plate is fixed through the split bolt through the wall element, and two metopes of lower layer's wall element are equipped with lower installation steel plate,

Between the vertical connection strap connection through mild steel material can either be risen in this way, connection strap vertical first is ideal as Weak link key effect
It to the effect of upper layer and lower layer wall element Weak link under to normal condition, and is destroyed in time when horizontal earthquake power is powerful, to protect
The follow-up lifting process of barrier；Moreover, repair process of the structure after earthquake is also very simple and convenient, it is only necessary to two above and below unscrewing
The split bolt of layer wall, replaces the new steel plate of installation up and down and vertical connection strap.
Another preferred structure of Weak link key is：Upper wall unit bottom is equipped with the thin beam to both sides evagination, lower layer
Wall element bottom also is provided with the thin beam to both sides evagination, and shearing bolt is bolted between upper layer and lower layer thin beam；Shearing bolt
Intensity is weaker than the intensity of the reinforcing bar of the steel reinforcement cage of upper layer and lower layer wall element；In this way, first, having equally constituted small intensity earthquake
It does not destroy, the triple protection of the earthquake of the eaerthquake damage shearing bolt of slightly larger intensity, larger intensity lifting metope；Moreover, but should
The same repair process of structure is convenient, after earthquake, it is only necessary to which after wall falls after rise and resets, the shearing bolt more renewed can be again
It uses, it is economical convenient to safeguard.
