Combined pouring mold for manufacturing assembly type building stairs

Technical Field

The utility model belongs to the technical field of the building, concretely relates to make assembled building stair's combination formula casting mold.

Background

With the development of modern industrial technology, building houses can be manufactured in batches and sets like machine production. The prefabricated house components are transported to a construction site to be assembled. The assembly type building has high construction speed and low production cost, and is rapidly popularized and developed all over the world. Early fabricated building profiles were rather rigid. Later improvements in design have resulted in increased flexibility and versatility to allow modular construction not only in batch, but also in a wide variety of styles. A movable dwelling is an advanced assembly type building, each dwelling unit is like a large trailer, and the dwelling unit can be used only by pulling the dwelling unit to the site by a special automobile and then hoisting the dwelling unit to a floor cushion block by a crane to be connected with a pre-buried water channel, a power supply and a telephone system. The movable dwelling house is internally provided with facilities such as a heating system, a bathroom, a kitchen, a dining room, a bedroom and the like. The movable dwellings can be formed into a unit independently or can be connected with each other.
