Abstract: A method of clinching two members together is provided together with a tool for performing the clinching operation. A staple is arranged with its web spanning members to be clinched together. The legs of the staple are forced together to effect the clinching. The tool to perform the operation is a pair of pincers. Each pincer is pivoted to the end of a spanning bar, the length of which corresponds to the length of the web of the staple to be used. The jaws are shaped to distort the legs of the staple to wrap around sides of members on closing of the jaws.

Abstract: A building system and/or an erected building is based on a kit of parts including portable, prefabricated wall sections of a width of 4 feet and a height dependent on the room height desired. The sections include a metal frame having parallel members to be vertical in the erected building. These members are provided with a thermal break along their length. The thermal break may also serve as a water resistant connector between sections. Sections are aligned with abutting side edges to form walls of the building. Parallel abutting vertical members of adjacent sections form composite load bearing members for roof trusses which may be spaced apart by the width of a wall section. A hinged template for interior partitions may be provided which can be folded for transport. Ceiling panels may be connected to roof trusses through an adjustable linkage so that compensation for movement of the roof trusses is possible.
