Problems solved by technology

[0003] Due to the narrow operating surface of the traditional stair formwork installation, nails are often used for formwork assembly, reinforcement, and time-consuming dismantling. The stair side formwork and step formwork are connected with nails, and it is easy to cause damage when dismantling them with crowbars. The damage of the concrete surface, and the long construction time affects the normal construction period

Abstract

The invention provides a stair concrete pouring formwork device. The stair concrete pouring formwork device comprises a bottom formwork, two side formworks and a plurality of transverse baffles. The two side formworks are fixedly connected to the two sides of the bottom formwork correspondingly. The bottom formwork and the two side formworks form a pouring chamber. Clamping groove openings are formed in the side formworks. The transverse baffles are inserted in the clamping groove openings of the side formworks. The stair concrete pouring formwork device has the beneficial technical effects that installing, dismantling and carpenter and bricklayer construction are convenient; concrete forming is good; the project quality is effectively ensured; and repeated use can be achieved. The invention further provides a stair concrete pouring method. The stair concrete pouring method comprises the following steps that chiseling is conducted on the floor section positions; secondary reinforcement binding is conducted on steel bars; the formwork device is loaded, the pouring chamber is formed, concrete is poured into the pouring chamber, and the transverse baffles are inserted in the clamping groove openings of the side formworks; leveling is conducted; and the formwork device is dismantled, so that pouring operation is completed. The width and the height of formed concrete stair steps are standard, and the stair appearance quality is improved.

Description

technical field [0001] The invention relates to a formwork device for pouring concrete for stairs. [0002] The invention also relates to a method for pouring concrete for stairs using the staircase formwork device. Background technique [0003] Due to the narrow operating surface of the traditional stair formwork installation, nails are often used for formwork assembly, reinforcement, and time-consuming dismantling. The stair side formwork and step formwork are connected with nails, and it is easy to cause damage when dismantling them with crowbars. The damage of the concrete surface, and the long construction time affects the normal construction period.
