One-time pouring forming method for interlayer beam

The invention discloses a one-time pouring forming method for an interlayer beam. The one-time pouring forming method comprises the following steps that concrete is poured from an upper frame beam by using a connecting structure of a constructional column, an upper frame beam and the interlayer beam, concrete is poured from the upper frame beam, so that the concrete flows into the interlayer beam through the upper frame beam and the constructional column; and the concrete is poured until upper frame beams, constructional columns and interlayer beams are filled with the concrete. According to the one-time pouring forming method for the interlayer beam, aiming at a traditional interlayer beam secondary reserving pouring method, the interlayer beam is poured together with the plate face concrete during main body construction, and the multiple problems that steel bar reserving is needed in traditional interlayer beam pouring, later feeding is difficult, the construction period is prolonged, and the labor cost is
