Description
Technical field
The utility model relates to a kind of engineering structure damping device, relates in particular to a kind of novel orthogonal laminated wood (CLT) and cutsPower wall power consumption connector, belongs to energy-dissipating and shock-absorbing and the vibration control technology of engineering structure.
Background technology
Orthogonal laminated wood (CLT, Cross-laminatedTimber) as a kind of innovation timber first in Austria andGermany proposes. Since then, this material is used widely at European residential architecture and non-residential structure field. ?Nearest several years, the use of European CLT just increased rapidly. All over the world, numerous impressive buildings and itsThe structure of its form is being used the so a kind of material of CLT, and this well proves that this material of CLT is used in closing of building fieldRationality. For CLT building, linked system is the core that affects its overall performance. At traditional C LT shear wallMiddle employing crab-bolt (hold-down) is connected under CLT shear wall condition with connectors such as supports (bracket), when havingWhen earthquake load or cyclic load, the sheet materials such as CLT shear wall mostly do not destroy in elastic stage, at connectorJunction, tear failure can occur, and this destruction is irreversible. Along with socioeconomic development, traditional guaranteeLife is safely the aseismatic design concept of target, can not meet the demand of current social development.
Based on such problem, the utility model proposes a kind of novel power consumption connector. This power consumption connector allows woodShear wall generation fine rotation, replaces original brittle break. And this power consumption connector is cheap, earthquakeWhen generation also by self-deformation dissipate seismic energy, after the earthquake can be by replacement.
Utility model content
The purpose of this utility model is poor in order to overcome traditional wooden Shear Walls angle connector energy dissipation capacity, Er QielianCan there is tear failure in the place of connecing, and wooden shear wall mostly in elastic stage, the problem of destroying does not occur, and proposes a kind of novelPower consumption connector, the distortion by self in the time that earthquake occurs carrys out dissipation capabilities, after the earthquake can replacement reducesThe disaster maintenance cost of timber buildings earthquake.
The technical solution adopted in the utility model is: a kind of orthogonal laminated wood shearing force wall energy-dissipation connector, comprises that power consumption connectsPart top, U-shaped bending mild steel plate, steel clamp plate and power consumption connector base; Described power consumption connector top and orthogonal gummedThe bar planting of wood shear wall body is connected; The both sides on power consumption connector top connect with two U-shaped bending mild steel plates respectively by boltConnect; Between two U-shaped bending mild steel plates, be provided with steel clamp plate, and be bolted, this bolt is at U-shaped bending mild steel platePreformed hole be vertical microscler track; Described power consumption connector base is by the base plate welding together, connecting plate, side steel plateWith ribbed stiffener composition, described connecting plate is connected with steel clamp plate by bolt, and described base plate is connected with flooring by bolt, instituteState side steel plate in vertical direction with 4 degree angles, side steel plate is close to orthogonal laminated wood shear wall, between side steel plate and base plate, establishesThere is ribbed stiffener.
As preferably, described power consumption connector top is connected with the bar planting of orthogonal laminated wood shear wall body, and bar planting adopts screw threadReinforcing bar, adopts epoxy or polyurethane adhesive.
As preferably, all bolts connect and all adopt high-strength bolt.
In the utility model power consumption connector, curved plates adopts mild steel plate, and other members adopt general steel plate. Consumption power consumptionConnector side arranges the steel plate in vertical direction with 4 °, allows the rotation of CLT shear wall and resists its horizontal shear.Outside curve mild steel plate stays the preformed hole of length-specific, controls the upper and lower displacement of power consumption connector. The utility model power consumption connectsFitting can not only use in CLT shear wall, also can be applied in other similar fabricated shear walls and go. This practicalityNovelly that is to say requirement of engineering and damping requirement according to the bearing capacity demand to CLT shear wall in different CLT structures, adjustBending mild steel plate dimensional parameters, bending soft board side direction preformed hole length.
The beneficial effects of the utility model are: the utility model has overcome traditional CLT shear wall and passed corner connector power consumptionAbility is poor, and tear failure can occur in junction, and CLT shear wall does not mostly all break in elastic stageBad; Can pass through again lateral rails, control the upper and lower displacement of shear wall, effectively controlled CLT timber buildings layerBetween Displacement Ratio. By this power consumption connector, the distortion by self in the time that earthquake occurs carrys out dissipation capabilities, after the earthquakeCan not need to repair or replacement power consumption mild steel plate, and can recover its original use function, build thereby reduce timber structureBuild the disaster maintenance cost of earthquake.
The utility model designs based on bending surrender thought, and core adopts Low Yield Point Steel; By reasonable Arrangement andDesign power consumption connector, can ensure that shear wall possesses fine intensity and initial stiffness, can ensure that again shear wall does in earthquakeUsed time surrender power consumption, avoids structural deterioration, thereby plays the protective effect to structure. The utility model novel energy-consumption connectsConnector, advantages of simple, most of assembly can be prefabricated in factory, and assembling is simple at the scene; Meanwhile, also reduced and executedThe labour intensity of work, has improved efficiency of construction.
