When the distribution reinforcement of described precast unit adopts closed stirrup, a limb of the section of exposing is vertical with the precast unit side, and a limb and precast unit side acutangulate or obtuse angle.
The distribution reinforcement section of exposing of described precast unit comprises two parts, and the part that connects precast unit is acute angle or obtuse angle with the angle of precast unit side, and remainder is vertical with the precast unit side.
The distribution reinforcement section of exposing of described precast unit is all acute angle or obtuse angle with the angle of precast unit side; Perhaps a part of distribution reinforcement section of exposing is acute angle with the angle of precast unit side, and another part distribution reinforcement section of exposing is obtuse angle with the angle of precast unit side; Perhaps a part of distribution reinforcement section of exposing is right angle with the angle of precast unit side, and another part distribution reinforcement section of exposing is acute angle or obtuse angle with the angle of precast unit side.
Described precast unit comprises distribution reinforcement more than 2 layers or 2 layers, and the angle of described distribution reinforcement and precast unit side is acute angle or obtuse angle.2 layers of distribution reinforcement of body of wall one general configuration, when body of wall is thicker, need distribution reinforcement more than 3 layers or 3 layers.Can the part distribution reinforcement and the angle of precast unit side be acute angle or obtuse angle, the angle of part distribution reinforcement and precast unit side is right angle: the two-layer distribution reinforcement in body of wall both sides is the reinforcing bar that diagonally distributes, and the intermediate layer distribution reinforcement is vertical with the precast unit side; Perhaps the two-layer distribution reinforcement in body of wall both sides is vertical with the precast unit side, and the intermediate layer distribution reinforcement is the reinforcing bar that diagonally distributes.
The present invention's beneficial effect compared with prior art.Precast unit of the present invention, compare with existing prefabricated units, is characterised in that the bidirectional crossed distribution reinforcement of its internal configurations and the angle of precast unit side are acute angle or obtuse angle, can effectively resist the suffered shearing of body of wall like this; Precast unit is stretched out in the one or both ends of distribution reinforcement, the section of exposing is acute angle or obtuse angle with the angle of precast unit side, can reduce like this slippage between pouring concrete after precast concrete and seam crossing, switching performance between stiffener, the reliability of raising precast concrete.
The present invention can be used for, containing the shear wall structure body of wall of shear wall structure or Frame _ Shear Wall Structure for example, also can be used for the body of wall of other wall body structures; Also can be used in the members such as floor.
