ABSTRACT:
A telescoping wall joint system is disclosed, for connecting adjacent sections of an architectural structure, while accommodating substantial relative movement, such as might result from seismic activity Extended motion is provided in the joint system while avoiding the use of excessively wide components, which are both costly and aesthetically undesirable. A center cover plate, which spans the open space between two adjacent structural units, is received along one or both sides in a tubular sleeve. The cover plate is slidably extendable within a predetermined range in the tubular sleeves to accommodate normal movements of the structural units, such as may result from thermal expansion and contraction, for example. The tubular sleeves themselves are slidably received within fixed housings mounted on the respective structural units. When the separating movement of two adjacent structural units becomes so great that the cover plate reaches a limit condition in its slidable extension out of the tubular sleeves, the sleeves themselves slidably extend in relation to the housings in which they are carried. The capacity of the system to accommodate separating movement of the structures is thus greatly increased.
