The demoulding is realized in bar and demoulding nut screw connection, exterior sheathing movement together with demoulding nut under the rotation of demoulding screw mandrel.
It is an advantage of the current invention that：
1）By being provided with the screw-rod structure that external thread rod and nut are worked in coordination in precast beam inner template, by the tune to nut
Section realizes the position adjustments during assembling to inner-film plate, is easy to quick positioning and quick assembling, carries out after concrete has been poured
Fast quick-detach is realized by the cooperation of nut and external thread rod when template is dismantled；
2）Moulding board of precast beam can pass through connection wire rod when building by top board mould bases, side plate mould bases, base plate mould bases and fillet mould bases
Single module, then integral moduleization assembling are connected into, the quick assembling for realizing moulding board of precast beam is built, and is conducive to overall mould
Blockization is dismantled.
