  • the method of manufacture of an edifice utilizing such load transfer devices between wood boards is also encompassed within this invention. Background of the Invention.
  • Composite wood boards such as plywood boards or oriented strand boards, are well- known in the construction industry. In fact, such boards are used in the manufacture of inclined roofs. To facilitate making the roofs, board manufacturers sell rectangular boards which are about four feet wide, eight feet long and about 3/8 to 3 A of an inch thick. Such boards are generally not attached to a roofing frame with each .board abutting another. Such spacing is required to compensate for expansion possibilities due to changes in moisture content during the lifetime of the roof itself. As such, there is needed a manner of providing sealing between the spaces of such roof component boards. This is typically accomplished with tape, or any other like material. The tape is applied to ends of adjacent boards and
  • Another advantage of such a device and method is the ability of a user to easily install such devices within target wood boards and further connect an adjacent wood board thereto through the utilization of at least one such device in order to keep such wood boards in place for a sufficient period of time prior to attachment to a roof frame.
  • the invention herein may be summarized as a structure for an edifice selected from the group consisting of a roof and a wall, wherein said structure is comprised of at least a first wood board and a second wood board, each of said first and second wood boards having a top portion and a bottom portion, and each having four peripheral edges, wherein at least one peripheral edge of each wood board includes at least one cavity therein for the insertion of at least one connection device; wherein said connection device is made of a durable material and having a first end and a second end and wherein each of said first and second end is configured to be inserted within said at least one cavity of each wood board; wherein when said first and second wood boards are contacted simultaneously with said device, said peripheral edges into which said device is inserted are parallel to each other, but are not in contact with one another, and wherein said device does not contact the top or bottom portion of said first and second wood boards.

Abstract

L'invention concerne l'utilisation d'un dispositif de transfert de charge spécifique qui permet une connexion et une adhérence fiables de panneaux de bois composites lors de la construction avec ces panneaux. Ce dispositif est conçu pour le confinement dans des fentes taillées dans les bords périphériques de ces panneaux de bois et dont la forme est complémentaire de celle du dispositif. Ainsi, introduit dans la fente de forme appropriée, ledit dispositif permet de séparer des panneaux de bois contigus séquentiellement appliqués sur le cadre de l'édifice cible et, enfin de compte, une résistance à la charge suffisante pour la construction en général (par exemple un toit) faisant appel à ces panneaux de bois reliés. La séparation des panneaux de bois permet donc une étanchéité appropriée entre ces panneaux (moyennant bande, mastic ou autre matériau analogue), ainsi qu'une distance appropriée pour le retrait ou le gonflement (du fait de l'humidité/de variations de température) dont on doit tenir compte pendant la durée utile du bâtiment (ce qui permet l'expansion au besoin). L'aptitude de conférer une résistance à la charge accrue autorise donc également un accroissement des matériaux de construction (en nombre et en poids) à porter et à conserver sur une telle structure durant la construction. L'invention concerne enfin le procédé de construction d'un édifice faisant appel à de tels dispositifs de transfert de charge entre les panneaux de bois.
