In precast concrete, between precast unit, have horizontal joint, vertical abutment joint etc., the stress performance of seam has determined integrality performance of the structure.Between existing precast unit, seam connects comparatively complexity, and globality is poor.
Summary of the invention
The invention provides a kind of precast unit, can facilitate the installation of precast unit to be connected with reinforcing bar, improve the stress performance of seam, guarantee the globality of structure, improve building structure industrialized level.
For achieving the above object, the present invention proposes a kind of precast unit, and this precast unit is precast reinforced concrete structure, and side has longitudinal fluting, there is concrete thin plates longitudinal fluting both sides, are connected with row or the above transverse reinforcement of row between concrete thin plates; Adopt transverse reinforcement to connect concrete thin plates, can improve the globality between precast concrete and rear pouring concrete; Transverse reinforcement, in longitudinal fluting, is conveniently made and transportation; Conveniently in longitudinal fluting arrange that other reinforcing bars connect together precast unit, for example, by placing reinforced steel bar ring and described transverse reinforcement joins mutually, concreting.Link one or more steel bar girders or one or a web perforate light gauge cold-formed steel shape at longitudinal fluting both sides concrete thin plates, can reach identical technique effect.The chord member of steel bar girder is embedded in the concrete thin plates of described longitudinal fluting both sides, and web member connects concrete thin plates.The edge of a wing of light gauge cold-formed steel shape is embedded in the concrete thin plates of longitudinal fluting both sides, and it is Z-shaped or I-shaped etc. that its cross section can be C shape.In described longitudinal fluting, be provided with vertical muscle, vertical muscle is in transverse reinforcement or steel bar girder inner side.On described vertical muscle, hang with ring steel reinforced bar; Ring steel reinforced bar can be movable comparatively freely on vertical muscle, in transportation, hoisting process, can be hidden in longitudinal fluting.After precast unit hoisted in position, then ring steel reinforced bar is fixed.
Described precast unit has longitudinal hole, can be square hole, circular hole etc.In order to water after increasing in the globality of longitudinal hole inner concrete, longitudinally between hole and longitudinal fluting, have horizontal hole.Or have horizontal hole between the longitudinal fluting of precast unit both sides.
In the longitudinal fluting of described precast unit, there is horizontal concrete slab, connect longitudinal fluting both sides concrete thin plates; In order to increase the globality of rear pouring concrete and precast concrete, laterally on concrete slab, have hole.Described vertical muscle is through the hole on horizontal concrete slab.
The present invention compared with prior art has following advantage.
There is longitudinal fluting precast unit of the present invention side, is connected with transverse reinforcement between longitudinal fluting, connects concrete thin plates, can improve the globality between precast concrete and rear pouring concrete; Transverse reinforcement, in longitudinal fluting, is conveniently made and transportation.On between precast unit, hang with ring steel reinforced bar, ring steel reinforced bar can be movable comparatively freely on vertical muscle, can be hidden in longitudinal fluting convenient construction in transportation, hoisting process; And ring steel reinforced bar location is convenient.
