Abstract
Abstract A wall construction of timber planks connected by connecting members with dovetailed slots provided in the planks arranged to be engaged by dovetailed projections on the connecting member. The slots are greater in depth than the dovetailed projections and a clearance area is provided adjacent to the center of the connecting member so that the dovetailed projection may move into the dovetailed slot and then move along the dovetailed slot with a minimum of frictional engagement until the timber planks being joined come together whereupon the dovetailed projections are tightened in the respective dovetailed slots.

A wall construction comprising timber planks constituting the wall and at least one timber plank constituting an internal partition, and connecting members for connecting the timber planks in assembled position, said timber planks each having at least one transverse dovetailed slot extending from the surface where a joint between a wall plank and the internal partition plank is to be formed, each connecting member including a longitudinal rigid member provided with two aligned dovetailed projections extending on either side of the longitudinal centerline, with each dovetailed projection being complementary to the dovetailed slot formed in the timber plank but with the depth of the dovetailed projection being less than the depth of the dovetailed slot, the connecting member being of a length to extend between the wall plank and the internal partition plank in the assembled position, the connecting member having longitudinal slots extending inwardly from either side of the center portion thereof for forming a throated section providing a clearance area adjacent the center of the connecting member, chamfered corners adjacent the entrance to the dovetailed slot, said longitudinal slots and chamfered corners providing a clearance area so that when the planks are engaged with a connecting member, the clearance area will initially allow the dovetailed projection to move into the dovetailed slot for reducing the frictional engagement between the splayed sides of the dovetailed projection and the sides of the dovetailed slot, and the internal partition plank in its face adjacent the entrance to the slot being provided with a shallow recess, the sides of the recess being inclined inwardly to form a projecting lip with the distance between the lips being slightly less than the thickness of the wall plank and the internal partition plank thereby ensuring that when the internal partition plank is in final position to complete the joint, a sharp, clean connecting line is provided between the wall plank and the internal partition plank.
