Based on the principle of the vertical die equipment, a die cavity for pouring the double-T-shaped beam can be formed by adjusting the relative positions of the templates, and a prefabricated component of the double-T-shaped beam can be obtained after pouring, so that the industrial production of the double-T-shaped beam is realized.
After pouring, the double-T-shaped beam is required to be prestressed and tensioned, namely holes are reserved on two sides of the double-T-shaped beam, steel strands or steel bundles pass through the holes in the later stage, tension is applied to two ends of the steel strands or the steel bundles, prestress is generated, and the effect of the double-T-shaped beam in prestressed and tensioned is to increase the bending bearing capacity and fatigue life of the double-T-shaped concrete beam and prevent crack expansion of the double-T-shaped beam, so that the overall stability and bearing capacity of the double-T-shaped beam are improved.
After a double T-shaped beam is poured by using a vertical die machine in the prior art, the prestressed tensioning process is usually carried out by hanging and then tensioning, and the concrete process is as follows: because the bending-resistant bearing capacity and the crack expansion preventing capacity of the double-T-shaped beam formed by casting are still insufficient, a plurality of groups of round steel hanging rings are pre-embedded in a die cavity before casting, and after casting, the double-T-shaped beam is lifted by utilizing the cooperation of a lifting truss and the round steel hanging rings and is lifted into a beam storage area for prestress tension.

If the prior art vertical die machine is used for tensioning the strip die, namely, the casting is carried out before and after the casting is carried out, the double T-shaped beam can deform in the prestress tensioning process due to the space limitation of the die cavity, so that the double T-shaped beam can arch in the tensioning process of the strip die, the double T-shaped beam can be extruded with the die plate, prestress loss is easy to occur, the double T-shaped beam can be in a clamping state with the die plate after the strip die tensioning, the vertical die machine can be carried up during the follow-up lifting, and great potential safety hazards exist.
