Description
Technical Field
The utility model relates to an one-way superimposed sheet and formwork structure of muscle can not go out in tip tongue-and-groove is applicable to the construction of superimposed sheet and cast-in-place roof beam.
Background
The fabricated concrete building is a reinforced concrete structure building which is formed by partially or completely assembling prefabricated concrete components on a main structure. In order to ensure that the integral stress performance of the assembled reinforced concrete structure is equal to that of the integrally cast structure, corresponding reliable construction measures and construction methods are required to be adopted, so that the prefabricated part, the cast-in-place part, the node and the like in the assembled structure can work in a cooperative manner, and the stress performance of the assembled reinforced concrete structure is equal to or higher than that of the integrally cast structure.
At present, beam columns are constructed in a cast-in-place mode, plates are made of prefabricated composite slabs, the construction mode is one of the construction modes commonly used at present, but in a system that the floor slabs are made of the prefabricated composite slabs and concrete beams are cast in place, collision problems exist between beam top longitudinal steel bars and the prefabricated composite slabs and extend outwards 'Huzi bars'. If the beam reinforcing steel bars are bound firstly, and the composite slab is lifted later, the problem of 'putting up' of the outward extending 'beard bars' and the longitudinal reinforcing steel bars of the beam in the lifting process is caused. On the one hand has prolonged the activity duration that superimposed sheet and cast-in-place roof beam are connected greatly, and on the other hand is to superimposed sheet hoist and mount process because overhanging beard muscle and roof beam are indulged the muscle collision, leads to the overhanging "beard muscle" of precast laminated sheet to be buckled, has increaseed work load when leading to precast concrete board fracture. On the contrary, the superimposed sheet is installed earlier, then must install earlier the beam slab template for hoist and mount provide operating space, then adopt the mode of interlude to carry out the ligature of beam reinforcement, this kind of mode also is consuming time and consumes labour on the one hand, on the other hand because beam side template must install earlier, leads to the roof beam bottom to indulge the ligature of muscle and stirrup and hardly target in place, especially is close to the beam-ends of post, and the beam-ends reinforcing bar of two directions alternates each other in nuclear core area, can't adopt traditional bed hedgehopping mode ligature roof beam bottom to indulge muscle and stirrup.
