Description

Stair Casting Mould Fastening Device

technical field

The utility model relates to the technical field of construction appliances, in particular to a stair casting mould fastening device.

Background technique

Building stairs are divided into cast-in-place stairs and prefabricated stairs according to different production processes. Among them, cast-in-place stairs require on-site formwork support, binding of steel bars, concrete pouring, formwork removal, etc. There are many on-site procedures and a large amount of support, making it difficult to pass through the structural construction stage. With the continuous advancement of construction industrialization, prefabricated stairs are widely used, and the standardization requirements of prefabricated stairs are relatively high. In order to improve the standardization and mass production of prefabricated stairs, prefabricated stairs are used to produce prefabricated stairs.

Among them, when arranging the pouring mold, the staff first arranges the bottom mold on the ground, and then lifts the side mold from the stacking place of the side mold to the bottom mold with a crane, and when the crane puts down the side mold, work The personnel straightens the side mold, and then arranges the other side mold. After completing the arrangement of the two side molds, the staff moves the end mold to the position where it is in contact with the side mold, and aligns it, and finally uses bolts or screws. The bottom mold and the two side molds are fixedly connected together to form a pouring cavity. After the pouring is completed, the top plate is pressurized to make the mold shape. However, when the existing top plate is pressurized, it is generally applied by adding counterweights. The hoist drops the counterweight into the top plate, and then removes the counterweight by the hoist when finished. This method consumes a lot of power, and there are certain safety hazards during the back and forth transfer of the crane, and it also has certain requirements for the storage yard.
