ABSTRACT:
A building press for joining building components which includes a frame having a fixed portion and at least one movable hammer, which frame is designed to receive a predetermined number of building components and to join the components with selected fasteners by means of fluid pressure such as air. The frame is equipped with at least one expandable conduit or several air, steam or hydraulic cylinders positioned between a fixed member of the frame and the hammer or hammers, and in a preferred embodiment, a multiplicity of fasteners are magnetically positioned on segments of the hammer to be driven into the building components. When a fluid such as air, oil or water is forced through the conduit the conduit expands and the hammer or hammers force the nail plates into the building components to securely join the components in a selected configuration. In the alternative, the components may be joined by applying hydraulic pressure on several hydraulic cylinders by means of air, steam, oil or other suitable fluid.
