Technical field
The invention belongs to prefabricated reinforced concrete structure component technology field, relate in particular to a kind of precast reinforced concrete structure that is applicable to cast in place and precast construction.
Background technology
In monolithic reinforced concrete structure work progress, field fabrication is many, and wet trade is many, has the intermediate links such as a large amount of form work engineerings, scaffolding work, waste resource, contaminated environment; Practitioner's quality, job site environment etc. are very large on build guality impact, bring the problems such as building performance, quality and durability.Change the present situation of monolithic reinforced concrete structure, should greatly develop precast concrete.The primary structure member of precast concrete is made in factory, and production efficiency is high, quality good, and saving resource and the energy, be conducive to sustainable development.Adopting precast concrete is the direction of industrialization of construction industry development, is also the direction of housing industrialization development.
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 prefabricated units, seam connects comparatively complicated.
Summary of the invention
The invention provides a kind of precast reinforced concrete structure, can facilitate the installation of precast reinforced concrete structure to be connected with reinforcing bar, improve the stress performance of seam, improve building structure industrialized level.
For achieving the above object, the present invention proposes a kind of precast reinforced concrete structure, and this member side has longitudinal fluting, and there is concrete thin plates longitudinal fluting both sides; The side of described longitudinal fluting both sides thin plate has transverse concave groove, and the two sides of transverse concave groove are connected with reinforcing bar, and reinforcing bar is fully anchoring in precast reinforced concrete structure; On described reinforcing bar, hang with reinforcing bar or reinforced steel bar ring; Described reinforced steel bar ring is closed stirrup or welded reinforcement ring.Because the reinforcing bar between precast reinforced concrete structure can be anchored in transverse concave groove or longitudinal fluting, therefore can reduce the distance between precast unit, reduce template amount.Reinforced steel bar ring hangs on precast reinforced concrete structure, and convenient transportation, installation, be conveniently connected with other member reinforcing steel bars.
Between the longitudinal fluting both sides thin plate of described precast reinforced concrete structure side, be connected with row or the above reinforcing bar of row; Or be connected with one or more steel bar girders between the thin plate of longitudinal fluting both sides; Or between the thin plate of described longitudinal fluting both sides, be connected with one or a web perforate light gauge cold-formed steel shape.Adopt reinforcing bar connect concrete thin plates, can improve precast concrete and after water the globality between the rear pouring concrete in longitudinal fluting; Reinforcing bar, in longitudinal fluting, is conveniently made and transportation; Conveniently in longitudinal fluting arrange that reinforcing bar connects together prefabricated units, for example, by placing reinforced steel bar ring and described reinforcing bar joins mutually, concreting, different prefabricated units can be linked together.Link one or more steel bar girders or one or a web perforate light gauge cold-formed steel shape at longitudinal fluting both sides thin plate, can reach identical technique effect.The chord member of steel bar girder is embedded in the thin plate 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 thin plate of longitudinal fluting both sides.It is Z-shaped or I-shaped etc. that its cross section can be C shape.
Described precast reinforced concrete structure has longitudinal hole, can 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.In the time that precast reinforced concrete structure does not have longitudinal hole, between its both sides longitudinal fluting, horizontal hole can be set.
The present invention compared with prior art has following advantage.
There is longitudinal fluting precast reinforced concrete structure of the present invention side, and the side of longitudinal fluting both sides thin plate has transverse concave groove, reinforcing bar connect transverse concave groove both sides, can improve precast concrete and after water the globality between the rear pouring concrete in longitudinal fluting; Connecting reinforcement between precast reinforced concrete structure can be anchored in longitudinal fluting, or is anchored in the transverse concave groove of side of longitudinal fluting both sides thin plate, reduces the spacing between precast reinforced concrete structure.In the time having reinforcing bar or steel bar girder etc. to connect concrete thin plates between longitudinal fluting, can improve the globality between the rear pouring concrete in precast concrete and longitudinal fluting; Reinforcing bar, in longitudinal fluting, is conveniently made and transportation.Connecting reinforcement between prefabricated units stretches in longitudinal fluting, has improved the globality between prefabricated units; Connecting reinforcement between prefabricated units forms cage of reinforcement with the reinforcing bar that is connected concrete thin plates, has guaranteed connection integrity.Precast reinforced concrete structure of the present invention hangs with reinforced steel bar ring or reinforcing bar, and reinforced steel bar ring or reinforcing bar are hinged on prefabricated units, can freely adjust within the specific limits position, facilitates reinforcing bar connection between transportation, installation and the prefabricated units of precast reinforced concrete structure etc.
