An elastomeric joint seal for architectural structures is provided with a multi-part cover and employs special anchoring hardware at least partially, and preferably entirely, mounted outside of the joint. The preferred mounting hardware comprises channels for receiving anchoring ribs of the multi-part cover. The main portion of the cover spans and seals the architectural joint, and is secured in the mounting hardware by anchoring ribs at each side. Cover strips are also anchored in the mounting hardware, and cover any exposed portions of the mounting hardware. The effective width of the joint is increased, by locating the mounting hardware outside of the joint space, which enables the joint to be designed to a narrower width dimension. The cover strips may be of a different color than the main seal to minimize the sight line. Significant economies are realized in the manufacture and installation, in part because the multi-part cover construction enables smaller and therefore less expensive extrusion equipment to be employed, and in part because the traditional difficulties involved in preparing the joint faces and in installing the mounting hardware within the joint space are avoided.
In a sealing system for an architectural joint separating adjacent structural units, wherein the structural units have confronting, spaced-apart joint faces defining a joint space and wherein at least one of the structural units has an external surface disposed at a substantial angle to said joint faces, and which comprises,
