Description

The shaped steel connected node of prefabricated shear wall

Technical field

The utility model relates to prefabricated component in a kind of building prefabrication structure, particularly relates to a kind of shaped steel connected node of prefabricated shear wall.

Background technology

It is fast that prefabricated assembled shear wall structure system has speed of application, the construction civilization, environmental pollution is little, advantages such as house type is flexible, be very suitable for building high residential building, but owing to reasons such as there are vertical reinforcement connection difficulty in the common vertical connected node of shear wall at present, construction is located and verticality control is difficult, anti-seismic performance is unreliable, this system is still used less in actual engineering.

The utility model content

For solving the difficulty of prefabricated shear wall connected node design and construction, the utility model proposes a kind of shaped steel connected node of prefabricated shear wall, by the technical program in the shaped steel connected node of prefabricated shear wall, the standard link position of mutual correspondence and fixedlying connected end to end of plano-convex built-in fitting are set, thereby have remedied the deficiencies in the prior art.

For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of shaped steel connected node of prefabricated shear wall, it includes precast unit, precast reinforced, described precast reinforced casting in the precast unit, be provided with vertically elongated dihedral shaped steel at inner edge place, precast unit both sides, on the centre position of the upper and lower of precast unit, be respectively arranged with H shape shaped steel, upper end at dihedral shaped steel that is positioned at precast unit top and H shape shaped steel is fixedly connected with the termination square plate separately, beyond the lower end of dihedral shaped steel that is positioned at the precast unit bottom and H shape shaped steel reaches the lower surface of precast unit.

Described two, dihedral shaped steel upper and lower that is positioned at inner edge place, precast unit both sides is set with respectively and the perpendicular angle steel edge of a wing stiffening rib in two outsides of dihedral shaped steel.

The shaped steel connected node of prefabricated shear wall of the present utility model, by pre-buried shaped steel on the precast unit of newly-increased wallboard, increase the overall size of connected node square plate, built-in fitting that superposed precast unit lower end stretches out can be welded in satisfying the scope that construction permits requires, avoid angle steel not go up because of the butt joint that construction error causes, by being arranged on dihedral shaped steel and the H shape shaped steel in the precast unit, with the bending bearing capacity of reinforcement prefabricated units and the shear resistant capacity at middle part, increase the precast unit of wallboard outward newly for cross wall, the angle steel edge of a wing stiffening rib that middle part, the edge of a wing vertical direction that dihedral shaped steel is taked is set up, strengthen the concatenation ability of dihedral shaped steel end, reach the purpose of end concatenation ability greater than angle steel mother metal concatenation ability.

Beneficial effect after the employing technique scheme is, the shaped steel connected node of the prefabricated shear wall of the utility model, by increasing the dihedral shaped steel and the H shape shaped steel of precast unit, the connection precision that two precast units are connected improves, by not rolling over down after the connected node connection, it is quick and convenient to construct, and wet-less operation in the time of can accomplishing construction, no template, the environmental protection operation that noise is low, whole anti-seismic performance is reliable, precast unit is to process in prefabrication practice, on-site construction time is very short, overall cost is lower, and the utility model can be widely used in the various prefabricated shear wall structure systems.
