Description
Technical field
The utility model belongs to prefabricated reinforced concrete structure component technology field, relates in particular to a kind of precast reinforced concrete structure that is applicable to assembled monolithic concrete structure.
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.In order to improve the stress performance of seam, on precast reinforced concrete structure, reserved connecting reinforcement, is connected with other members.In prior art, connecting reinforcement and precast reinforced concrete structure be for being rigidly connected, and in the time of transport, lifting, connecting reinforcement can hinder that precast reinforced concrete structure is put, location etc., and seam connects complicatedly simultaneously, and stress performance is difficult for ensureing.While making with the precast reinforced concrete structure of reserved steel bar, will reserve conduit etc. and allow reserved steel bar stretch out outside template in template, concrete easily overflows everywhere from preformed groove; Existing technique generally arranges fritter template etc. at conduit place, makes complexity, has reduced the industrialized level of precast reinforced concrete structure.
Summary of the invention
The utility model provides a kind of precast reinforced concrete structure, can facilitate the installation of precast reinforced concrete structure to be connected with reinforcing bar, improves the stress performance of seam, improves building structure industrialized level.
For achieving the above object, the utility model proposes a kind of precast reinforced concrete structure, in described precast reinforced concrete structure, have longitudinal hole, longitudinal edge interval arranges the transverse concave groove crossing with longitudinal hole; In longitudinal hole, vertical muscle is set, transverse concave groove place arranges ring steel reinforced bar, and described ring steel reinforced bar hangs on described vertical muscle, in the region that vertical muscle surrounds from ring steel reinforced bar, passes through.Ring steel reinforced bar is welded reinforcement ring, or is closed stirrup etc.; It is shaped as rectangle or circle etc.Described vertical muscle is one or more, can be also the reinforcing cage that many vertical muscle and stirrup form.Described precast reinforced concrete structure at least has a longitudinal hole.Adopt such technical scheme, ring steel reinforced bar is hinged on precast reinforced concrete structure, can freely adjust within the specific limits position, in the processes such as transport, lifting, ring steel reinforced bar does not expose precast reinforced concrete structure, or ring steel reinforced bar part is exposed precast reinforced concrete structure, convenient transport, lifting etc.; After hoisted in position, ring steel reinforced bar is extracted out, be connected easy construction with the reinforcing bar of other members.The manufacturing process of the precast reinforced concrete structure the utility model proposes in two steps, is first manufactured with the precast reinforced concrete structure of longitudinal hole and transverse concave groove, now on precast reinforced concrete structure, does not have embedded bar to expose; Ring steel reinforced bar is set after precast reinforced concrete structure completes in transverse concave groove again, longitudinally in hole, the vertical muscle through ring steel reinforced bar being set, ring steel reinforced bar is hung on vertical muscle.The precast reinforced concrete structure the utility model proposes can adopt 3D printing technique to make.Described longitudinal hole is perforation hole, or does not connect hole.
The ring steel reinforced bar length of described precast reinforced concrete structure meets and the interconnective requirement of other member reinforcing steel bars.
There is in-line concrete thin plates the one or both sides of the transverse concave groove of described precast reinforced concrete structure.
There is L shaped concrete thin plates the one or both sides of the transverse concave groove of described precast reinforced concrete structure.Can be used in the L shaped node connection or floor connection of precast reinforced concrete structure, or the seam of other precast concretes.
The utility model compared with prior art has following advantage.
(1) precast reinforced concrete structure of the present utility model hangs with ring steel reinforced bar, ring steel reinforced bar is hinged on prefabricated units, can freely adjust within the specific limits position, can be hidden in precast reinforced concrete structure, facilitate transport, the lifting of precast reinforced concrete structure, facilitate reinforcing bar connection between prefabricated units etc., greatly facilitate precast concrete construction.
(2) there is transverse concave groove precast reinforced concrete structure of the present utility model side, and transverse concave groove, with longitudinally hole is crossing, can improve the globality of seam.
(3) precast reinforced concrete structure of the present utility model can improve the industrialized level of precast concrete.Existing precast reinforced concrete structure side reserved steel bar, job site in reserved steel bar place again configuration reinforcement realize the connection between prefabricated units; Ring steel reinforced bar in the utility model can replace the reinforcing bar that in prior art, job site configures on reserved steel bar, reduces job site reinforcing bar configuration quantity, and the part reinforced bar engineering of job site is transferred to factory, improves industrialization of construction industry level.
(4) the utility model can facilitate precast reinforced concrete structure to make, and improves and makes quality.In prior art, when precast reinforced concrete structure in making with embedded bar, grooving is wanted in the position that in template, reinforcing bar stretches out; For preventing that concrete from overflowing, grooving place arranges foamed plastics, fritter template etc., affects production efficiency.When precast reinforced concrete structure has two or two above up and down side by side when reinforcing bar, the grooving place between reinforcing bar is difficult to process side by side, and concrete is easy to overflow, and affects precast reinforced concrete structure quality.The utility model, in manufacturing process, does not stretch out reinforcing bar on precast reinforced concrete structure, therefore can avoid above-mentioned rough sledding.
