Abstract
A modular post and beam joint includes slidably and tightly interfitting transverse beam members and primary and secondary post members. The latter define slots receiving the interfitting transverse beam members, as well as fingers which project endwise oppositely at the four corners defined by the transverse beam members.
Claims3
In a modular post and beam joint, the combination comprising
- a. first and second transverse beam members defining an intersection with four corners which are vertically elongated, and
- b. primary and secondary post members having end portions which extend vertically endwise oppositely in interfitting relation with said beam members at said intersection,
- c. the primary post member end portion containing transverse slots which intersect so as to closely receive upper extents of said transverse beam members, and defining four fingers which project downwardly at said respective four corners,
- d. the secondary post member end portion containing transverse slots which intersect so as to closely receive lower extents of said transverse beam members, and defining four fingers which project upwardly at said respective four corners,
- e. said primary and secondary post member end portions having equal lengths, said primary post member end portion terminating in adjacent relation to the secondary post member end portion, the post members having sliding frictional interfit with the beam members,
- f. said first and second beam members containing vertically extending notches respectively receiving second and first beam member extents at said beam member intersection and concealed inwardly of said fingers, and
- g. said first and second beam members having chamfered surfaces that are interengaged inwardly of edges defined by said fingers, said chamfered interengaged surfaces holding said members in rigid assembled relation.
