Under deck drainage system

Abstract

An under deck drainage system for a fluidly pervious deck of light frame construction provides paired spacedly opposed elongate fastening brackets, carried on adjacent surfaces of opposed pairs of deck supporting joists, with a downwardly curving drainage panel extending therebetween to receive and transport drainage to a deck edge perpendicular to the joists. The fastening brackets are sealed against the joists carrying them and provide two vertically spaced fastening arms that sealably engage the edges of the drainage panel carried therebetween in a releasable, positionally maintainable interconnection of opposed tooth-like fastening ridges carried by the drainage panel edges and the fastening arms.

Description

BACKGROUND OF INVENTION RELATED APPLICATIONS [0001] There are no applications related hereto heretofore filed in this or in any foreign country by the Applicant. FIELD OF INVENTION [0002] My invention relates generally to light frame structures and more particularly to a drainage system for placement under a fluidly pervious deck to remove drainage from beneath the deck to an outer deck edge. BACKGROUND AND DESCRIPTION OF PRIOR ART [0003] Decks in light frame construction commonly are supported spacedly above a surface such as from the floor level of a half or second story of a main structure having its first story at or below earth level. Such decks are commonly formed with spaced horizontal joists extending outwardly from the main structure to support surfacing boards extending angularly to the joist in a closely spaced array so that fluidic and other smaller solid environmental debris may passed downwardly through spaces between the surfacing boards to be wasted in some fashion b...

Benefits of technology

[0022] A still further object is to provide such a drainage system that has a drainage panel of downwardly curving arcuate cross-section, the medial portion of which can be moved upwardly to move partially constrained panel edges away from each other to aid fastenable establishment of the panel edges between fastening

Problems solved by technology

Such deck construction has become popular in modern light frame architecture, but notwithstanding its popularity this deck construction commonly limits and disrupts the use of space beneath an elevated deck, which often is not desirable.

Despite the lengthy developmental history of solutions to under deck drainage problems, the past solutions have not adequately nor completely resolved all problems and various problems still remain.

Principal among problems remaining with prior under deck drainage systems are firstly, that such drainage systems are not sealed, or if sealed are not adequately sealed, so as to prevent leakage from the drainage system either on the surface beneath the serviced decks or on the deck structures that support the drainage system and secondly, that such drainage systems are difficult to install and positionally maintain in operative mode in either new construction or especially in existing construction.
