摘要： Floor slabs are precast in situ one upon another, temporary steel lifting columns are mounted through aligned clearance holes in the stack of slabs, a holding carriage and a lifting carriage are operatively disposed about each of the columns, threaded tension rods are coupled to removable tension rod sections properly located and coupled to the slabs, lifting jacks mounted on the lifting carriage actuate the tension rods to lift the entire stack of slabs to a height adjacently above the final elevation of the lowermost of the slabs in the stack, the pack of slabs is held by the holding carriage until the lifting carriage is raised to a further lifting height, the lowermost slab in the stack is temporarily supported at its highest elevation and is released from the lifting tension rods so that the remaining slabs can be raised and the successive lowermost slabs dropped off at their predetermined elevated positions, while angular wall columns are mounted in position to provide the ultimate support for the lowermost slab which is then lowered onto such columns and released from the temporary holding means. After all of the slabs have been erected, the lifting equipment is removed for reuse. To facilitate handling and placement of the wall columns one or more cranes may be mounted on and ride up with the topmost slab.

摘要： A method of and means for erecting precast slabs in building construction wherein the slabs are supported on prefabricated temporary generally rectangular walkthrough self-stable shoring frame assembly. A generally U-shaped base member is assembled with a staff structure which may be in the form of an inverted U-shaped arrangement in which upstanding arms on the base member are telescopically adjustably connected with depending arm extensions of the staff member. Diagonal, adjustable struts may connect cooperating units of the shoring frame assembly. Combination slab lifting and shoring frame locating pin-like fingers are provided.

摘要： A method for securing a cladding plate to a building substrate by means of an expandable material, such as a hydrophobic polyurethane foam, which is capable of expanding many times its original volume is disclosed. The hydrophobic polyurethane foam is introduced into a space between the cladding plate and the building substrate so as to create an adhesive bond between adjacent surfaces of the cladding plate and building substrate. The foam is introduced into the space either as a free flowing liquid dispensed into a retention basin created in the space or by means of a balloon from which it will expand freely upon fracturing of the balloon. The balloon is constructed so that it will break shortly after the material has turned into foam but before the material has lost its capability of adhering to the cladding plate and building substrate, and before the balloon pressure can overcome the retaining pressure delivered by the cladding plate and building substrate.
