Prefabricated PC laminated slab and cast-in-place beam structure and construction technology thereof
The invention discloses a prefabricated PC laminated slab and cast-in-place beam structure and a construction technology thereof. The technical problem that in the prior art, prefabricated PC laminated slab steel bars need to be repeatedly bent on a construction site, so that the practical quality of the prefabricated PC laminated slab steel bars is affected or the construction period is prolonged is solved. The structure comprises a cast-in-place beam, a prefabricated PC laminated slab and a cast-in-place floor slab; the prefabricated PC laminated slab is provided with a prefabricated laminated slab steel bar, the prefabricated laminated slab steel bar comprises an embedded section, a first bent section, a second bent section and an anchoring section, and the anchoring section is obliquely and downwards anchored in the cast-in-place beam from the top of the cast-in-place beam. The construction process mainly comprises the following steps: obliquely inserting the middle anchoring section of the prefabricated PC laminated slab reinforcement in place into the top of the cast-in-place beam from top to bottom, paving the cast-in-place floor slab reinforcement, and then pouring the cast-in-place beam and the cast-in-place floor slab. According to the invention, the steel bars of the prefabricated laminated slab do not need to be repeatedly bent on the construction site to ensure that the use quality is not influenced or the main bars and stirrups of the cast-in-place beam do not need to be bound firstly and the mounting space is reserved for the prefabricated PC laminated slab to shorten the construction period.
本发明公开了一种预制PC叠合板与现浇梁结构及其施工工艺，解决现有技术需在施工现场反复折弯预制PC叠合板钢筋影响其实用品质或增加施工工期的技术问题。本发明结构包括现浇梁、预制PC叠合板和现浇楼板；预制PC叠合板设预制叠合板钢筋，预制叠合板钢筋包括预埋段、第一折弯段、第二折弯段和锚固段，锚固段从现浇梁顶部倾斜向下锚固于现浇梁内。施工工艺主要是将就位后的预制PC叠合板钢筋中锚固段从上至下斜插入现浇梁顶部并铺上现浇楼板钢筋后浇筑现浇梁和现浇楼板。本发明无需将预制叠合板钢筋在施工现场反复弯折以保证其使用品质不受影响或无需先将现浇梁的主筋及箍筋先不进行绑扎而给预制PC叠合板预留安装空间以缩短施工工期。
