ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to architectural constructions and, more particularly, to bearing wall constructions for small buildings.
2. The Prior Art
A myriad of wall constructions have been proposed for small, as well as large, architectures. Such constructions have involved various materials ranging from concrete to wood to fiberboard in various units ranging from blocks to beams to sheets. There is a need for an improved small architectural construction that facilitates the use, by amateurs as well as professionals, of standardized materials that are handy to use and that produce predictable results.
SUMMARY OF THE INVENTION
This invention is a complete insulating wall bearing system made of a multiplicity of elongated flat planks laid flat side down end to end and course upon course in a fashion unique to the building trades. This invention concerns the construction of walls between a top plate and a sill at the base of a wall. The system makes use of a dense rigid insulating material for a load bearing wall. The system makes use of an insert placed in a non-structural, non-connecting expansion or shrinkage joint. The system makes use of fasteners, such as long nails or screws, which secure courses in a vertical fashion and also prevent horizontal shear. The vertical stability of the constructed wall is determined by the width at the base of the wall. This stability is increased by an imposed load at the top. Additional vertical structural members are not required. Abutting planks in a horizontal course are not structurally engaged. Rather, they are secured to continuous courses of planks below and above a joint.
Thus, the primary object of the present invention is to facilitate the construction of bearing walls by use of superposed courses of planks that are characterized by a novel combination of composition, geometry and arrangement. These planks preferably are composed of a homogenized dispersion of fiber and binder, preferably, cellulosic fiber and organic binder. This material has been found to have a suitably high compression coefficient, to be chemically inert as a practical matter from the standpoint of resistance to atmospheric conditions, and to be inexpensively produced, for example, from recycled newsprint or the like. It is to be understood, however, that these planks, in alternative embodiments of the present invention, may be composed of lumber, plywood, particle board and the like. The planks generally have dimensions which enable standardized production and ease of assembly. The planks generally are substantially greater in width than in thickness. As a result, their effective moment of compression has a maximal vertical vector and a minimal horizontal vector, by which buckling is inherently precluded. The contiguous ends of abutting planks are spaced from each other by about ⅛
th
inch. Pairs of the planks are provided at matched end locations with aligned notches for the reception of inserts that establish weather-tight joints. The purpose of these inserts is to establish weather-tight joints and to allow movement during wall construction. The planks are nailed or otherwise interlocked in staggered joints, by which the integrity of the construction is securely maintained. Preferably, the planks have vertical cutouts, which reduce weight and which, when aligned, establish channels for the insertion of utility conduits.
Other objects of the invention will in part be obvious and will in part appear hereinafter.
