ABSTRACT:
BACKGROUND OF THE INVENTION
1. Filed of the Invention
This invention relates to the use of stucco as a wall appliqué with corner trim components to define the perimeter of stucco wall.
2. Prior Art
Stucco is a cementitious compound utilized as a building finish that is applied to the walls of those buildings, to make them weatherproof and have a finished appearance. Stucco is primarily utilized in the south and southwestern portions of the United States prior to the introduction of improved insulating techniques. Such techniques have led to improvements for use in wetter climates. Such an improvements have culminated into a development of a method and apparatus for the application of multiple layers of material to an existing wall, so as to produce a water impenetreble MASTERBOND™ stucco structure as described in my aforementioned patent applications.
A MASTERBOND™ stucco structure is processed by a series of steps. Such steps include pressure washing (if necessary) on the existing wall, which is then cleaned, rinsed and air dried. After the wall has been properly washed and dried, an arrangement of orientation screeds is applied to the margins of the wall including and inside or outside quarters thereon. A screed is a border support onto which the insulation is to be sprayed.
In my first aforementioned patent application, a screed is described having a ship-lap shape, or a cross-section of generally L-shaped having a shoulder on its spray foam-adjacent edge, so as to provide a key or locking affect onto that foam. The foam is also sprayed onto the wall surface. The screed in that embodiment is attached to the wall by an adhesive and/or mechanical fasteners.
It is an object of the present invention to provide a stucco trim assembly which is an improvement over the prior art trim arrangements.
It is a further object of the present invention to provide a stucco trim assembly which is of simple design and is inexpensive to manufacture.
It is a yet further object of the present invention, to provide a stucco trim or screed assembly which is adjustable in its assembly and adjustable in its stucco holding capacity.
It is still yet a further object of the present invention to provide a stucco trim assembly which is readily attachable to a wall and readily adjusted thereon by the personal applying the stucco coating.
BRIEF SUMMARY OF THE INVENTION
The present invention comprises a stucco trim assembly for emplacement on a corner of a wall to facilitate the securement and dimensional consistency of the stucco being placed thereon.
The stucco trim assembly, in a first embodiment, is configured for an outside or external corner emplacement. The stucco trim assembly comprises an extruded elongated receiving trim member and an extruded elongated inserted frame clip. The elongated receiving trim member comprises an extruded component of plastic or metal having an elongated first securement web and an elongated second securement web meeting along a common juncture at an angle of 90 degrees. The elongated first securement web and the elongated second securement web each have a plurality of spaced apart perforations thereon, to provide a gripping surface for receipt of and securement of stucco when it is applied thereagainst and onto a wall surface.
A projecting channel frame is unitary with the juncture of the first securement web and the second securement web and is directed into a direction away from the first and second securement webs. The elongated projecting channel frame has a distalmost edge. The distalmost edge of the projecting channel frame has an elongated channel extending therewithin. The elongated channel has a plurality of elongated spaced apart barbs or ribs directed toward one another in an opposing fashion, within the elongated channel of the projecting channel frame.
The inserted frame clip of the first embodiment of the stucco trim assembly comprises an elongated central frame member having an elongated distalmost edge. The elongated central frame member has a second edge which defines a juncture for an elongated first outer web and an elongated second outer web unitarily extruded therewith and adjoined together at the second edge of the elongated central frame member. The elongated first outer web and the elongated second outer web each have an outer surface having a rough portion or texture thereon for bonding or securement of applied foam and stucco material thereto. The elongated central frame member has a plurality of elongated spaced apart ribs or barbs on each side thereof in spaced relationship to the opposed barbs spaced apart from one another within the channel of the projecting channel frame member of the receiving trim member.
The elongated frame member of the inserted frame is designed to be snapped (or slid) into the receiving channel of the projecting channel frame member at successively adjustable depths therewithin. The spaced apart barbs or ribs on the elongated frame member may be mated with the valleys between adjacent spaced apart and opposed ribs or barbs in the receiving channel of the projecting channel frame. The inserted frame clip may therefore define an outer surface which is adjustably matable within the channel of the receiving trim member to permit a foam and stucco material to be placed on a wall and within the boundaries defined by the stucco trim assembly, at any of several desired thicknesses, according to the needs of the construction undertaken.
A further embodiment of the stucco trim assembly comprises a receiving trim member for an inside or inner corner or a pair of walls meeting along an inner corner. The stucco trim assembly of this embodiment also includes an inserted frame clip arranged to adjustably mate with an elongated channel in the elongated projecting channel frame of the stucco trim assembly. The stucco trim assembly for this embodiment has a first securement web and a second securement web meeting at an elongated juncture, the first and second securement webs defining an angle of 90 degrees from one another. The elongated first and second securement webs in this embodiment, are bisected by the elongated projecting channel frame member. The inserted frame clip of this embodiment has a first outer web and a second out web which meet at an elongated unitary juncture comprising a second edge of the elongated frame portion thereof. The elongated first outer web and the elongated second outer web define an angle of 90 degrees with respect to one another along the elongated juncture. The elongated frame portion of this embodiment has a plurality of spaced apart ribs or barbs arranged in a matter similar to that of the aforementioned first embodiment. The receiving frame portion has an elongated channel disposed within the projecting channel frame in a manner similar to that of the aforementioned embodiment. The inserted frame portion of the inserted clip may be thus inserted within the channel of the receiving frame portion into a depth of any one of several distances so as to provide a selective spaced distance between the first outer web and the first securement web to permit controlled thickness adjustment of the foam and stucco material applied to the wall surfaces meeting at the inner wall juncture where the stucco trim assembly of this second embodiment, is placed.
Thus is what has been shown is a unique extruded assembly which permits guidance for application of foam and stucco material to adjacent wall surfaces, in a convenient and easily adjustable manner. The elongated outer webs or securement webs each having irregular surface characteristics permit bonding of the foam and stucco material thereto, facilitating securement and longevity to the stucco assembly.
The invention thus comprises a stucco trim assembly for emplacement onto a corner defined by the juncture of a pair of walls, to permit a foamf and stucco material to be controllably and adjustably secured to the walls. The assembly comprises an elongated receiving trim member attachable to a corner of said pair of walls; and an elongated inserted frame clip, w
