In precast concrete, between prefabricated units, 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 reinforced concrete structure, can facilitate the installation of precast unit to be connected with reinforcing bar, improve the stress performance of seam, guarantee the globality that member connects, improve building structure industrialized level.
For achieving the above object, the present invention proposes a kind of precast reinforced concrete structure, by connector, precast concrete plank is linked together; Described connector is reinforcing bar or light gauge cold-formed steel shape or steel bar girder etc., and connector two ends anchor in precast concrete plank; Described precast concrete plank side has transverse concave groove, and the two sides of transverse concave groove are connected with reinforcing bar, and reinforcing bar, through transverse concave groove, anchors in the concrete of transverse concave groove both sides, hangs with reinforcing bar or reinforced steel bar ring on this reinforcing bar.Size, the shape of transverse concave groove are determined according to stressed, making etc.The chord member of steel bar girder is embedded in precast concrete plank.The edge of a wing of light gauge cold-formed steel shape is embedded in precast concrete plank, and it is Z-shaped or I-shaped etc. that its cross section can be C shape; For increasing globality, light gauge cold-formed steel shape has hole.
The precast concrete plank medial surface of described precast reinforced concrete structure is male and fomale(M&F) or crude, to increase precast concrete and rear pouring concrete connection integrity.
The precast reinforced concrete structure that the present invention proposes can be for vertical members such as bodies of wall: precast reinforced concrete structure is erect, and in the space surrounding at precast concrete plank, concreting can form wall body construction; Or in the space surrounding at precast concrete plank, fill insulant material etc. forms heat-preserving wall.The precast reinforced concrete structure that the present invention proposes can be in the horizontal members such as floor: precast reinforced concrete structure is being kept flat, concreting in the space surrounding at precast concrete plank, or in the space surrounding at precast concrete plank and its on concreting form floor member.
The present invention compared with prior art has following advantage.
Precast reinforced concrete structure of the present invention can reduce the weight of precast unit, convenient transportation installation etc.The precast concrete plank side of composition precast reinforced concrete structure has transverse concave groove, and transverse concave groove two sides are connected with reinforcing bar, can improve the globality between precast concrete and rear pouring concrete, facilitates reinforcing bar connection between prefabricated units.On the reinforcing bar of connection transverse concave groove two sides, hang with reinforced steel bar ring or reinforcing bar, reinforced steel bar ring or reinforcing bar are hinged on precast unit, can freely adjust within the specific limits position, facilitate reinforcing bar connection between transportation, installation and the prefabricated units of precast reinforced concrete structure etc.
