Abstract
Abstract This invention relates to a cast monolithic house and to an apparatus for casting, simultaneously, the roof, end wall and sidewalls thereof at the site. The method involves hinging together roof and sidewall forming portions of a form and lifting such form into place by wheeled carriers which are guided by jigs on the floor of the house. Jacks, mounted on the wheeled carriers, will lift the form into place. Wall form positioning linkage is connected between the wheeled carriers and the sidewall forming portions of the form to retract or expand them into normal vertical position in wedging relationship with floor bucks serving as base portions of said sidewall forming portions.
