A technique of construction is disclosed utilizing a plurality of upright posts bored from the top to define a bore that is coaxial with the post, there being cutaway portions entering into the sides of the post and communicating with the coaxial bore. A plurality of beams each has a tongue at both ends, the tongues fitting within the cutaway portions and being secured within the coaxial bore in the respective post. This securing is done with pins which are driven down into detent bores in the ends of the tongues, and the entire coaxial bore and pin and tongue detent structure is hidden by virtue of an overlying cap which is a press-fit into the coaxial bore, defining a flush surface with the top of the post.
