The expansion joint in the
Bruner System is protected by patents and has proven in many years of usage
to be permanently waterproof and to successfully allow for expansion and
construction of glass and concrete without injury. The joint, as shown,
connects sections which are otherwise distinctly separate, closing when the
construction expands, opening when the construction contracts. These
joints are placed fifteen to twenty feet apart, depending upon local
conditions at the building.
Because of the wedge shape
glass the Bruner System only can be repaired easily and quickly by the
insertion of "repair glass." This process is patented, and where such
repairs are made they are absolutely and permanently waterproof and
cannot be noticed.
Each concrete rib contains
two reinforcing bars,-- a shear and tension rod. As shown in the cut on
page two, these bars are held one-half inch from the
bottom of the concrete ribs by wire hangers, hung between every glass, which
keeps the reinforcing rods from being exposed and tie the ribs to the slab.
Cross tie-rods distribute the strain in case of a concentrated load, and
bind the construction together.
