Abstract: A spacer member for maintaining substantially uniform joint spacing between construction elements during construction of a static structure comprising a plurality of construction elements bound to one another by curable matrix material. The spacer member remains embedded in and covered by the matrix material and permits the matrix material to be placed in and completely fill all construction joints between the construction elements in a single application. The spacer member includes structure located interiorly of the planes of the exposed faces of the construction elements for positively establishing and maintaining a desired position of the spacer member during construction of the structure.

Abstract: A glass block wall has a frame member that frictionally engages the glass block adjacent thereto. A continuous flexible spacer member extends along the horizontal end walls of the glass blocks in each course. Separate vertical spacer members abut the adjacent vertical end walls of the glass blocks and a filler material is positioned in the recess formed between the edges of the adjacent glass blocks and the edge of the spacer member. The spacer members have a configuration to align the glass blocks in the wall and to stabilize each of the glass blocks in the wall.
