Structural frame for a building

Claim 2

A structural frame constructed with preformed posts and beams connected by unitary joints formed at the construction site, said frame comprising: upright posts disposed in superposed relation with adjacent ends thereof substantially in vertical alignment and having axial bores extending a predetermined distance into the upper and lower ends thereof; sleeves in said bores; a rod disposed in said sleeves and bottomed in said bores of said adjacent superposed posts and having a length sufficient to support said upper post a predetermined distance above said lower post and providing a cavity therebetween defined by the projections of the aligned walls thereof; means removably attached to said posts for enclosing said cavity and having an aperture therein for permitting access thereto; a uniting piece formed at the building site in said enclosing means and allowed to cure in order to form a unitary joint uniting said posts together to provide an upright column with said posts; one or more horizontal beams having generally rectangular cross sections and having one end positioned adjacent and above the upper end of said lower post outside of said cavity and having its end surface aligned flush with the adjacent vertical side wall of said lower post; and, wherein said uniting piece forms a unitary joint uniting said posts and beams together; the cross-sectional area of at least one of said beams being less than the surface area of the cavity adjacent to the end surface of said beam; and, wherein said enclosing means includes removable filler blocks having sufficient dimensions to fill the voids left in the enclosing means by the smaller beam and having their end surfaces aligned flush with the end surfaces of said beam outside said cavity.

Claim 3

The structural frame of claim 1 wherein at least one of said beams has a width narrower than the width of said posts, said beam having its outside vertical side wall aligned in the plane of the corresponding outside vertical side wall of said posts; and, wherein said enclosing means includes a removable filler block supported adjacent the inside vertical sidewall of said beam and having a width equal to the difference between the beam width and the post width and having its end surface aligned flush with the end surface of said beam outside said cavity so as to fill the void left in the enclosing means by the narrow beam.

Claim 4

The structural frame of claim 2 wherein the inner vertical sidewall of the beam is aligned with the corresponding inner surface of the post.

Claim 5

The structural frame of claim 1 wherein the height of at least one of said beams is less than the vertical space between said upper and lower posts; and, wherein said enclosing means includes a removable filler block supported under the beam and having a height equal to the difference between the height of the beam and the vertical space between the upper and lower posts and having its end surface aligned flush with the end surfaces of said beam outside said cavity, so as to fill the void left in the enclosing means by the thin beam.

Claim 6

The structural frame according to claim 1 wherein the height of at least one of said beams is less than the vertical space between said upper and lower posts; and, wherein said enclosing means includes removeable filler blocks supported under the beam and having a height equal to the difference in height between the height of the beam and the vertical space between the upper and lower posts said filler block having its end surface recessed from the end of the beam so as to provide a joint with reinforcing projections under said beam.

Claim 7

A structural frame constructed with preformed concrete posts and beams united by unitary concrete joints formed at the construction site, said frame comprising: a first upright post supported upon a footing having; a generally rectangular cross section; and, a first axial bore extending a predetermined distance into its upper end; a first cap molded in said first post at the end of said first bore; a first sleeve molded in said first bore and bottomed on said first cap; a rod disposed in said first sleeve and bottomed on said first cap extending a predetermined distance out of said first bore; a second upright post superposed above and aligned with said first post and having; the same generally rectangular cross section as said first post; second and third axial bores extending predetermined distances into its upper and lower ends respectively; and, second and third caps molded in said second post at the end of said second and third bores; second and third sleeves molded in second and third bores and bottomed on said second and third caps, respectively; said rod also disposed in said third sleeve and bottomed on said third cap and supporting said second post a predetermined distance above the top surface of said first post and providing a cavity therebetween defined by the projections of the aligned walls thereof; one or more horizontal beams having generally rectangular cross sections and having one end positioned adjacent and above the upper end of said first post outside said cavity and having at least one vertical sidewall thereof aligned with a vertical sidewall of said first post so that said post provides no direct support for said beams; means removably attached to said posts and beams for enclosing said cavity, said means having an aperture therein for permitting access thereto; and, a uniting piece of concrete poured at the building site into said cavity and allowed to cure in order to form a unitary joint thereof uniting said posts and beams.

Claim 8

A structural frame constructed with preformed concrete posts and beams united by unitary concrete joints formed at the construction site, said frame comprising: a first upright post supported upon a footing having; a generally rectangular cross section; and, a first axial bore extending a predetermined distance into its upper end; a first cap molded in said first post at the end of said first bore; a first sleeve molded in said first bore and bottomed on said first cap; a rod disposed in said first sleeve and bottomed on said first cap extending a predetermined distance out of said first bore; a second upright post superposed above and aligned with said first post and having; the same generally rectangular cross section as said first post; second and third axial bores extending predetermined distances into its upper and lower ends respectively; and, second and third caps molded in said second post at the end of said second and third bores; second and third sleeves molded in second and third bores and bottomed on said second and third caps, respectively; said rod also disposed in said third sleeve and bottomed on said third cap and supporting said second post a predetermined distance above the top surface of said first post and providing a cavity therebetween defined by the projections of the aligned walls thereof; one or more horizontal beams having generally rectangular cross sections and having one end positioned adjacent and above the upper end of said first post outside said cavity and having at least one vertical sidewall thereof aligned with a vertical sidewall of said first post so that said post provides no direct support for said beams; means removably attached to said posts and beams for enclosing said cavity, said means having an aperture therein for permitting access thereto; and, a uniting piece of concrete poured at the building site into said cavity and allowed to cure in order to form a unitary joint thereof uniting said posts and beams.
