Zusammenfassung:The utility model provides a novel tool type stair formwork facilitating surface finishing, and relates to the technical field of constructional engineering formworks. Multiple step formwork clamping grooves (5) are formed in the upper end of the inner wall of a bench side formwork body (1), multiple step formworks (2) are clamped inside the step formwork clamping grooves (5), fixed screw rod battens (3) are arranged on the outer side of the bench side formwork body (1), and the upper end and the lower end of each fixed screw rod batten (3) are fixed through opposite-pull screw rods (4). The tool type stair step formwork which is easy to machine, mount and dismount, low in cost and convenient to change is used for carrying out stair construction, and due to the fact that wood patterns which is only 1 cm thick of the formwork make contact with step concrete, surface finishing is not affected, and it is ensured that internal corners of finished products after pouring are plump.
