The invention discloses a set-shaped formwork support for construction of a connecting part of a bottom plate and an outer wall. The set-shaped formwork support comprises an inner side support and an outer side support which are correspondingly positioned at the inner side and the outer side of the outer wall, wherein the outer side bracket comprises an outer side formwork which can cling to the outer side surface of the outer wall, and at least two outer side square steel pipes for mounting the outer side formwork; the inner side bracket comprises an inner side formwork which can cling to the inner side surface of the outer wall, and at least two inner side square steel pipes for mounting the inner side formwork; bending parts which horizontally extend are arranged at the upper ends of the inner side square steel pipes and the outer side square steel pipes; the bending parts of the inner side square steel pipes and the bending parts of the outer side square steel pipes are sleeved with each other. According to the set-shaped formwork support, brick moulds are not constructed, and wall bolts and batten steel pipes are saved, so that the assembling is quick and convenient; after a concrete cushion is constructed, an additional waterproof layer and a waterproof layer can be constructed; in addition, the set-shaped formwork support is recycled, so that the cost can be reduced, and the resource can be saved.
