Prefabricated construction system meets the Resources for construction economizing type proposed in " 12 " planning, environment friend due to it The requirement of good type society, can effectively save resource and the energy, effect of the raising material in terms of real building energy conservation and structural behaviour Rate, reduces building waste and the harmful effect to environment, improves building function and structural behaviour, realizes " environmental protection of four energy-conservation one " Green Development and low energy consumption, the building course of low emission, promote the overall development of Building Trade in China, reach that predetermined energy-conservation subtracts Purpose is arranged, thus is had broad application prospects.From the point of view of existing prefabricated construction architectural study achievement, its anti-seismic performance Seam, the connection of reinforcing bar and the overall performance depended primarily between precast shear wall wallboard.Therefore, a kind of energy is developed The structural system for being enough adapted to the reinforcement manner of Standard formula construction is just particularly important.
The content of the invention
In order to realize the quick restorability of function of the structure after shake, it is easy to the fabricated construction and optimization structure of structure Reinforcement manner, the present invention, which have developed a kind of assembled for secretly burying truss, can recover function Coupled Shear Wall structural system.
A kind of assembled for secretly burying truss proposed by the present invention can recover function Coupled Shear Wall structural system, by wall limb, Some oblique reinforcing bars for secretly burying truss are provided with coupling beam, high-strength prestress drag-line and replaceable energy-dissipating device composition, wall limb, Wall limb bottom is provided with steel plate, wall limb bottom and basis top is disconnected in interface, the upper end anchoring of high-strength prestressed drag-line At the top of wall limb, anchoring lower ends are connected between foundation bottom, adjacent wall limb by coupling beam, and wall limb and coupling beam end are firm Connect, set in the interface on wall limb with basis and replaceable energy-dissipating device is also installed in the middle part of replaceable energy-dissipating device, coupling beam.
In the present invention, the wall limb is the armored concrete wall limb for secretly burying truss.
In the present invention, the high-strength prestress drag-line is deformed bar or prestress wire.
In the present invention, the replaceable energy-dissipating device is metal energy-dissipating device, viscoelasticity damping energy dissipation device, frictional damping It is any in energy-dissipating device or composite damping energy-dissipating device.
In the present invention, the reinforcement manner of the armored concrete wall limb for secretly burying truss for wall limb set in end it is vertical by Power reinforcing bar, and stirrup restraint end concrete is set, chevron shaped concealed bracings steel reinforcement cage is set in the middle of wall limb, and chevron shaped dark The upper and lower ends of support set horizontal reinforcement cage.
The beneficial effects of the present invention are:
(1)The present invention can effectively reduce the damage of coupling beam and wall limb bottom in shake in Coupled Shear Wall.The present invention passes through reality Existing the controlled of wall limb waves mechanism to mitigate the destruction of wall limb bottom.And the present invention in wall limb bottom by setting steel plate to reduce Collsion damage of the wall limb in rocking process with contact surface.Replaceable consumption of the invention by the way that the destruction of coupling beam to be concentrated on to middle part The damage of coupling beam can be reduced on device.
(2)The present invention is conducive to structure to realize the quick restorability of its function after shake.It is of the invention mainly will power consumption and Damage concentration in replaceable energy-dissipating device is conducive to that replaceable energy-dissipating device is repaired or changed after macroseism.
(3) residual deformation after the shake of the invention for effectively reducing structure.The present invention in wall limb by setting high intensity in advance should Power drag-line can provide self-resetting capability to structure, effectively reduce residual deformation after the shake of structure.
(4) amount of reinforcement of the present invention effectively reduction structure.Stress machine of the invention by optimizing wall limb and coupling beam Reason, on the premise of structural strength and rigidity is ensured, realizes the reduction of amount of reinforcement.
(5) present invention is advantageously implemented the fabricated construction of structure.Structural elements and energy-dissipating device in the present invention is equal It can be processed in precast plant.Due to the structural elements in the present invention, amount of reinforcement is reduced compared with traditional structure component, component Processing and splicing difficulty can be reduced.
