Abstract: A construction accessory for use with a construction panel includes a flange having an inner surface adapted to face the construction panel and an outer surface opposite the inner surface. The flange further includes at least one perforation extending through the flange between the inner surface and the outer surface and a depression in the inner surface. The depression is in communication with said at least one perforation.

Abstract: A panel support construction accessory includes a back flange and a bottom flange obliquely extending from the back flange. The bottom flange includes an array of perforations for permitting moisture removal. Preferably, the panel support construction accessory additionally includes a lower flange coupled to the bottom flange and spaced from the bottom flange to create a cavity below the array of perforations. A filter material, such as open cellular material, is supported adjacent the array of perforations. The filter material transmits moisture. Alternatively, the construction accessory includes a forward flange extending between the lower flange and the bottom flange in lieu of or in addition to the filter material. Preferably, at least one of the lower flange and the forward flange includes an opening that communicates with the cavity.

Abstract: An edge strip for being mounted along a base structure includes a first axially extending flange and a second axially extending flange obliquely extending from the first flange. The second flange includes a first support configured for being mounted adjacent to the base structure. The first support includes a head portion, a first neck portion between the head portion and the first flange, and a second neck portion spaced from the first neck portion between the head portion and the first flange.

Abstract: A joint assembly forming part of a gridwork of channel sections used as decorative partitions in various types of wall construction, the joint assembly including abutting, mitered channel sections, adhesive tape backing, and adhesive glue for bonding the abutting channel sections together and, additionally, a method of assembling said joint assemblies using adhesive tape backing and adhesive glue for bonding the sections together.

Abstract: A construction panel support member for attachment to a building structure in an end-to-end relationship with a second similar support member. The panel support member includes a back flange attachable to the structure, a bottom flange joined to the back flange at substantially 90 degrees, and a side flange joined to the bottom flange. The bottom flange including a top surface adapted to support a construction panel, and the side flange is substantially parallel with the back flange and extends upwardly from the top surface to a top flange. The top flange is substantially parallel to the top surface and extends from the side flange toward the back flange. The side flange includes a ridge which is substantially parallel to the top surface and extends from the side flange toward the back flange such that a groove is formed between the top surface, the ridge, and the side flange. The groove is adapted to accept a support element engageable with the second support member.
