Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the reinforced concrete precast beam of the present invention includes concrete 1, a plurality of longitudinal bars 2, and a plurality of stirrups 3; the longitudinal bars 2 and the stirrups 3 are arranged in the concrete 1, and the stirrups 3 are sleeved outside the longitudinal bars 2; still include a plurality of gusset plates 4, set up a plurality of muscle through-holes 5 of indulging on the face of gusset plate 4, indulge the quantity of muscle through-hole 5 and be not less than the quantity of indulging muscle 2, indulge muscle 2 and pass and indulge muscle through-hole 5. Preferably, the reinforcing plate 4 is disposed between two adjacent stirrups 3. During the use, at first will indulge muscle 2 and pass and indulge muscle through-hole 5 for every indulges muscle 2 and all indulges in muscle through-hole 5. The relative position between a plurality of vertical bars 2 is fixed, the integrity of the precast beam obtained after the concrete 1 is cast is increased, the structural strength is high, and the anti-seismic performance is high. Meanwhile, the relative position of the longitudinal bar 2 is fixed, so that the stirrup 3 can be conveniently bound, and the operation is convenient.

In order to facilitate the longitudinal bar 2 to pass through the longitudinal bar through hole 5, the diameter of the longitudinal bar through hole 5 is larger than the diameter of the longitudinal bar 2.
