Description

A kind of fabricated shear wall vertical abutment joint mild-steel energy-consumption attachment means
Technical field
The present invention relates to a kind of fabricated shear wall vertical abutment joint mild-steel energy-consumption interconnection technique device, belong to Structural Engineering skill Art field.
Background technology
Prefabricated assembled concrete structure refer to structure various components include precast shear wall, precast beam, precast floor slab, Precast shear wall etc. is standardized production in factory, is then bolted each prefabricated components at the construction field (site), welds The structure that connection, the connection of rear pouring concrete or prestressing force connection are installed.Each prefabricated components work of prefabricated concrete structure Industry metaplasia is produced, manufacture craft can more common site concrete it is more fine, with saving labour, construction speed is fast, be conducive to Realize building energy conservation, be easy to the advantages of industrialized production and mechanized construction, adapt to the developing direction of China's building industrialization.
The connection of vertical abutment joint makes the key technology in prefabricated assembled concrete shear wall structure between precast shear wall, Conventional vertical abutment joint connection method at present is mainly rear pouring concrete connection, and this mode situ wet operation workload is big, applies Work is complicated, and quality is difficult to ensure that, is unfavorable for energy-conserving and environment-protective.Therefore prefabricated assembled shear wall structure needs proposition more efficient quick Vertical abutment joint connected mode.
Generally, the globality and rigidity of fabricated shear wall structure are less than cast-in-place shear wall structure, and assembled is cut The anti-seismic performance of power wall construction is less than cast-in-place shear wall structure.Because fabricated shear wall structure is showed not in ago earthquake centre Good, people lack confidence, building industry of the fabricated shear wall structure in China to the anti-seismic performance of fabricated shear wall structure Middle application percentage is not very high.Energy-dissipating and shock-absorbing is applied into fabricated construction can reduce overall structure antidetonation demand, improve main body The anti-seismic performance of structure.
The content of the invention
The invention provides a kind of fabricated shear wall vertical abutment joint mild-steel energy-consumption attachment means, this kind of attachment means have The characteristics of being easy to industrialized production, improves the energy dissipation capacity of fabricated shear wall structure.
A kind of fabricated shear wall vertical abutment joint mild-steel energy-consumption attachment means of the present invention, including precast shear wall Piece, power consumption mild steel, anchor plate, bolt hole, nut and screw rod.
Further, it is that screw rod is nearby reserved in two sides in precast shear wall piece connection side, screw rod is welded in shearing in advance On steel reinforcement cage or it is anchored in armored concrete within the walls within the walls, it is ensured that screw rod can effectively transmit and spread internal force.Screw size is by cutting Power wall seam crossing shearing size is determined.
Further, the power consumption mild steel that precast shear wall piece is arranged with oblique two-way cross is connected, and power consumption mild steel is surrender Point is 235N/mm steel, and mild steel has good hysteretic characteristic after plastic range is entered, can in elastic and plastic deformation process Absorb substantial amounts of energy;The mild steel that consumes energy can be strip, column or along length variable cross-section, should ensure that effective force, and compared with Power consumption is surrendered under big load.Power consumption mild steel length and reserved screw position accurately should determine to ensure construction precision in advance.
Further, power consumption mild steel two ends welding anchor plate, anchor plate can have larger strength and stiffness for steel plate etc. Prepared screw-bolt hole on the square or circular slab that material is made, anchor plate, the size of bolt hole is determined regarding screw size.Nut is by anchor Backing plate is fixed on screw rod by prepared screw-bolt hole.
Further, power consumption mild steel and anchor plate can be welded in advance, be mounted directly be fixed on screw rod at the construction field (site), but Installation accuracy requires higher;Or power consumption mild steel and anchor plate Site Welding, installation accuracy can reduce.
Further, power consumption mild steel size and number pass through performance-based seismic design method control so that shear wall structure Reach more preferable energy consumption effect and anti-seismic performance.
The beneficial effects of the invention are as follows:
The present invention proposes a kind of fabricated shear wall vertical abutment joint mild-steel energy-consumption attachment means, and it has adapted to precast concrete The characteristics of being easy to industrialized production, and improve the energy dissipation capacity of fabricated shear wall structure.Precast shear wall piece connection side leads to Power consumption mild steel is crossed by precast shear wall piece drawknot, the globality of shear wall horizontal direction is kept.Sheared at shear wall vertical abutment joint Larger, the oblique two-way cross arrangement of power consumption mild steel can farthest utilize mild steel tensile yield energy dissipation behavior, and ensure two-way Power consumption.Present invention improves the rigidly connected performance of pouring concrete after tradition, prefabricated assembled concrete shear wall knot is increased The energy dissipation capacity of structure, has broken away from job site wet trade, energy-dissipating device has been combined with precast shear wall, the increase of Structural Energy Dissipation ability 30-60%, is easy to industrialized production, can be widely applied to prefabricated assembled concrete shear wall structure.
