Description
Technical field
This utility model is related to brick or concrete duct field, and prestressing force Self-resetting damage concentration is prefabricated waves for specifically a kind of segmentation
Shear wall.
Background technology
Earthquake often causes huge social influence and economic loss as paroxysmal natural disaster.According to specification
The normal concrete building of design can not fully meet the growing antidetonation demand of building.Structure is needed in calamities such as earthquakes
The lower structural damage of evil effect will not excessive development, can be under rational technical conditions and economic condition through repair can be extensive after calamity
Multiple its expectation function, that is, damage controlled architecture.
Structural damage is presented as the general effect of component damage, including damage type, degree of injury and damage profile three
Aspect.The purpose of structural damage control is that the damage of structure is limited in position set in advance, and makes these positions pre-
Degree of injury under phase macroseism is less than predetermined limit value, and residual deformation of the structure after shake is less than predetermined limit value.
Damage generally has following both sides effect to structure：After damage, the rigidity of structure is reduced, cycle stretch-out.This typically can
Increase the dynamic respond of structure, but the seismic force that structure is subject to can also decrease；It is certain that damage location tends to dissipation
Inputting seismic energy, so as to reduce the seismic response of structure.Therefore controlled damage for structural seismic performance be favourable.Damage
That hinders controlled architecture system it is critical only that the rationally and effectively deformation pattern of control structure and expected damage location.
In actual seismic demage analysis, the bottom shear wall destruction in shear wall structure or frame-shear-wall structure is very tight
Weight.Researchers have found that basic suitably lifting often contributes to reducing the geological process of superstructure, so as to mitigate structure shake
Evil.System is waved in the researcher proposition that takes the lead in of the country such as U.S., and the system passes through the constraint between loosening configuration and basis or component,
Allow structure or certain part of structure to wave under geological process, and utilize the collection for waving some positions of structure for causing
Middle deformation, by Damage Coutrol on " waving interface ".
Existing at present to wave wall member, the connection with agent structure designs not science.A monoblock wall is from bottom simultaneously
Apply the height that prestressing without bondn not only limit floor to top, also increase the unreliable degree of structure in earthquake.

Reserved presstressed reinforcing steel duct is additionally provided with presstressed reinforcing steel, and each body of wall, anchor is provided with the upper end of each reserved presstressed reinforcing steel duct
Tool, in neighboring walls, the nothing arranged in the reserved presstressed reinforcing steel duct in body of wall above and the body of wall being disposed below
Binding prestress reinforcement is corresponding, and after unbonded prestressing tendon penetrates corresponding reserved presstressed reinforcing steel duct, its upper end is by anchorage
Anchoring.
Wherein, the corner of each body of wall arranges damage concentration block.
Wherein, the damage concentration block in four corners of body of wall is that intensity meets less than the fibre reinforced cement base of body of wall main body
Material, it is affixed with body of wall main body.
Wherein, unbonded prestressing tendon one end that body of wall stretches out is anchored in the middle part in body of wall, and the other end is anchored in top
The top in body of wall correspondence duct.
Wherein, body of wall and agent structure beam soap-free emulsion polymeization, are fixed by gravity and the presstressed reinforcing steel through body of wall with beam.
Wherein, body of wall has the position of prestressed anchor and body of wall upper and lower end parts position concrete to be strengthened by tie hoop.
Beneficial effect：Prestressing force Self-resetting damage concentration is prefabricated waves shear wall for a kind of segmentation of the present utility model, has
Following beneficial effect：
1st, prefabricated components plant produced on-site consolidation, meets building industrialization requirement.Segmentation applies prestressing force, reduces construction
Difficulty, increase redundancy, it is to avoid somewhere prestressed failure and cause structure integrally to destroy.
2nd, construction damage positioning is waved in secondary structure on the damage concentration block on wall, realizes Damage Coutrol, protection master
Structure and time structure wave the main part of wall, and can realize quick reparation by damage concentration block after shake.
3rd, wave the shock behavior of lifting whereabouts using body of wall in earthquake, the rigidity of structure can be reduced, reduce structural cycle,
Earthquake energy, reduces geological process.The Self-resetting performance that prestressing force and dead load are realized simultaneously, can effectively reduce structure
Residual deformation.
