An improved load bearing elongated precast construction member is used for erecting a free standing load bearing wall including a plurality of the construction members. Each elongated construction member has a tongue on one load bearing edge and a groove on the other load bearing edge, and a passageway in the construction member for communicating with either the tongue or groove thereon for injecting structural grout into a space between a tongue on one construction member and a groove engaged therewith on another like construction member stacked thereon to form a unitary free standing load bearing wall of a building.

An elongated load bearing beam construction member for use in erecting a free standing wall comprising an elongated precast body having front and rear vertical side faces, first and second vertical end edges, and upper and lower horizontal load bearing edges, one of said upper and lower load bearing

An elongated load bearing beam construction member for use in erecting a free standing wall comprising an elongated precast body having front and rear vertical side faces, first and second vertical end edges, and upper and lower horizontal load bearing edges, one of said upper and lower load bearing edges and one of said first and second end edges having a tapered tongue extending lengthwise and outwardly thereof, said tongue having side surfaces extending convergingly outwardly from a base at said one load bearing edge and said one end edge, said tongue base being spaced inwardly of said side faces, the other of said upper and lower load bearing edges and the other of said first and second end edges having a groove extending lengthwise and inwardly thereof, said groove being spaced inwardly of said side faces distances the same as the distances of the base of said tongue from said side faces whereby said groove is of a size and shape for snugly engaging the base of a tapered tongue on one load bearing edge and one end edge of other like corresponding members, said groove being deeper than the height of said tongue on said one of said upper and lower load bearing edges and one of said first and second end edges on said other members whereby said groove is deeper than the height of said tongue on said other members so as to define therewith a structural grout receiving lengthwise space about said side surfaces of said tongue on said other members, and a passageway in said precast body communicating with either said tongue or groove for injecting structural grout under pressure into said space to form a unitary free standing load bearing wall.
