REINFORCED CEILING RUBBER AND METHOD OF REINFORCING A CEILING RUNNER

摘要

The strength and/or stiffness of a T-bar grid 2 having a double web 4 and cap 12 can be increased by coating the inside portion of the cap strip 12, or the bottom sides of the flanges 8 and 10 with a hot melt adhesive 16. Cooling sets the adhesive and results in the two parts of the grid member becoming a unitized structure.
