Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application Serial No. 63/164,279, filed March 22, 2021 , which is incorporated by reference in its entirety herein.

BACKGROUND

For buildings with varying types of thin veneers such as stucco, and sidings applied over varying thicknesses of outboard rigid insulation stucco-type exteriors, moisture drainage is important. Rainscreen drainage systems are commonly used with building structures such as exterior walls and windows to provide an air gap over a water resistive barrier to create a capillary break, which allows gravity to drain moisture and provides ventilation to dry out the materials. These rainscreen drainage systems must include functioning terminations. If not adequately drained and ventilated, the building materials can absorb moisture and eventually rot. Even with rainscreen drainage systems, rot can be a problem.
For the reasons stated above and for other reasons stated below, which will become apparent to those skilled in the art upon reading and understanding the present specification, there is a need in the art for a termination for building structures.

Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
It is to be understood that other embodiments may be utilized and mechanical changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense.
Embodiments of the disclosure generally provide a termination member configured and arranged to receive at least a portion of a terminal portion of a building veneer, which is part of a wall, for example a top of a wall, a bottom of a wall, and portions forming a window opening, to assist in moisture drainage and ventilation. Generally, the termination member includes a base onto which at least a portion of the terminal portion is seated and a connecting flange and a supporting flange extending from opposing sides of the base. At least a portion of the terminal portion is positioned between the connecting flange and the supporting flange. The connecting flange is configured and arranged to be connected to the building structure. The base is configured and arranged to drain moisture via gravity and provide ventilation.
A termination member can be used alone or in combination with another termination member. The termination member can include a drainage assembly. The termination member can include drainage apertures.
In one embodiment, illustrated in FIG. 1, a termination member 102 is an elongate member having a generally L-shaped profile. A base 103 interconnects a connecting flange 104 and a supporting flange 106. Preferably, the connecting flange 104 has a longitudinal bend 104a that allows a top portion including apertures 105 configured and arranged to receive fasteners to be connected to the building structure and allows a bottom portion to extend at an angle away from the building structure. The depth of the base 103, between the connecting flange 104 and the supporting flange 106, accommodates the portion of the terminal portion.
In an example, the base 103 has a depth of 3 inches, the connecting flange 104 has a height of 3 ½ inches, and the supporting flange 106 has a height of ¾ inches. The bottom portion of the connecting flange 104 is 1 ½ inches and the top portion of the connecting flange 104 is 2 inches. The bend 104a creates a gap of 1/8 inch from the building structure to the base 103.
As illustrated in FIGS. 3 and 4, an example termination member 102 also includes a drainage assembly 108. The drainage assembly 108 includes a drainage member 109 configured and arranged to create longitudinally extending voids or channels for drainage and ventilation, as shown in FIG. 4. Preferably, the drainage member 109 is made of corrugated spunbond with alternating outwardly and inwardly extending portions 110 and 112 creating outer and inner voids 111 and 113, respectively. Optionally, a filter member 115 is operatively connected to the drainage assembly 108 with adhesive, stitching, fasteners, or other suitable connecting means. Preferably, the filter member 115 is made of a lighter weight spunbond than the drainage member 109 and is not corrugated. The filter member 115 provides a filtering mechanism. Although corrugated spunbond and spunbond are described, it is recognized that any suitable material (e.g., screen material, etc.) and configuration could be used. For example, the drainage member could be corrugated, crimped, or folded to create the voids or channels.
Preferably, the termination member 102 is inserted into a termination member 118, which is a receiving termination member, as shown in FIGS. 3 and 4. The termination member 118 is illustrated in FIGS. 2 and 2A. The termination member 118 is an elongate member having a generally L-shaped profile. A base 119 interconnects a connecting flange 120 and a supporting flange 122. Preferably, the connecting flange 120 has a longitudinal bend 120a that allows a top portion including apertures 121, aligning with apertures 105, configured and arranged to receive fasteners to be connected to the building structure and allows a bottom portion to extend at an angle away from the building structure. The depth of the base 119, between the connecting flange 120 and the supporting flange 122, accommodates the portion of the terminal portion.
In an example, the base 119 has a depth of 3 1/8 inches, the connecting flange 120 has a height of 3 ½ inches, and the supporting flange 122 has a height of ¾ inches. The bottom portion of the connecting flange 120 is 1 ½ inches and the top portion of the connecting flange 120 is 2 inches. The bend 120a creates a gap of 1/8 inch from the building structure to the base 119.
The termination member 102 fits within the termination member 118, and this assembly is used along the head of a window opening (on top of a window). The termination member 102 is sloped relative to the termination member 118 and provides longitudinally extending voids for drainage and ventilation, and the termination member 118 provides a surface generally aligned with the top of the window for aesthetics. A portion of the veneer can be applied to an exterior surface of the termination member 118 so that it blends with the rest of the exterior. The termination member 102 can be sloped from one end to the other end or it can include a bend proximate the middle to slope downward toward both ends. The gap between the building structure and the bottom portions of the bases 103 and 119 provide additional ventilation. Preferably, the termination members 102 and 118 are made from stainless steel to resist corrosion and be fire resistant. Preferably, the termination members 102 and 118 are made in 8 feet lengths and one or more assemblies can be used along a terminal portion of a building.
In one embodiment, termination member 118 can be used alone, for example along sides of a window opening, as shown in FIG. 15.
In one embodiment, illustrated in FIGS. 5-9, a termination member 126 is an elongate member having a generally L-shaped profile. A base 127 interconnects a connecting flange 128 and a supporting flange 131. Proximate the connecting flange 128, the base 127 includes drainage apertures 129, which can be slots extending from the base 127 to or into the connecting flange 128, and the base 127 is angled with a slope 143 toward the drainage apertures 129 to facilitate drainage. Preferably, the connecting flange 128 has a longitudinal bend 128a that allows a top portion including apertures 130 configured and arranged to receive fasteners to be connected to the building structure and allows a bottom portion to extend at an angle away from the building structure. The depth of the base 127, between the connecting flange 128 and the supporting flange 131, accommodates the portion of the terminal portion.
In an example, the base 127 has a depth of 3 1/8 inches, the connecting flange 128 has a height of 3 ½ inches, and the supporting flange 131 has a height of ¾ inches. The bottom portion of the connecting flange 128 is 1 ½ inches and the top portion of the connecting flange 128 is 2 inches. The bend 128a creates a gap of 1/8 inch from the building structure to the base 127. The angle of the base 127 provides a gap or slope 143 of 1/8 inch from a side of the base 127 proximate the supporting flange 131 to a side of the base 127 proximate the connecting flange 128.
As illustrated in FIGS. 7 and 8, the termination member 126 includes a drainage assembly 134. The drainage assembly 134 includes a drainage member 135 configured and arranged to create laterally extending voids or channels for drainage toward the drainage apertures 129 and ventilation, as illustrated in FIGS. 8 and 9. Preferably, the drainage member 135 is made of corrugated spunbond with alternating upwardly and downwardly extending portions 136 and 138 creating top and bottom voids 137 and 139. Optionally, a filter member 141 is operatively connected to the drainage assembly 134 with adhesive, stitching, fasteners, or other suitable connecting means. Preferably, the filter member 141 is made of a lighter weight spunbond than the drainage member 134 and is not corrugated. The filter member 141 provides a filtering mechanism. Although corrugated spunbond and spunbond are described, it is recognized that any suitable material (e.g., screen material, etc.) and configuration could be used. For example, the drainage member could be corrugated, crimped, or folded to create the voids or channels.
Termination member 126 can be used alone, for example along a window sill (bottom of a window opening), as shown in FIG. 16.
In one embodiment, illustrated in FIGS. 10-12, a termination member 146 is an elongate member having a generally L-shaped profile. A base 147 interconnects a connecting flange 148 and a supporting flange 150. Proximate the supporting flange 150, the base 147 includes drainage apertures 151, which can be slots extending from the base 147 to or into the supporting flange 150, and the base 147 is angled with a slope 153 toward the drainage apertures 151 to facilitate drainage. Preferably, the connecting flange 148 has a longitudinal bend 148a that allows a top portion including apertures 149 configured and arranged to receive fasteners to be connected to the building structure and allows a bottom portion to extend at an angle away from the building structure. The depth of the base 147, between the connecting flange 148 and the supporting flange 150, accommodates the portion of the terminal portion.
In an example, the base 147 has a depth of 3 1/8 inches, the connecting flange 148 has a height of 3 ½ inches, and the supporting flange 150 has a height of % inches. The bottom portion of the connecting flange 148 is 1 ½ inches and the top portion of the connecting flange 148 is 2 inches. The bend 148a creates a gap of 1/8 inch from the building structure to the base 147. The angle of the base 147 provides a gap or slope 153 of 1/8 inch from a side of the base 147 proximate the supporting flange 150 to a side of the base 147 proximate the connecting flange 148.
Termination member 146 can be used alone, for example along a bottom of a veneer, as shown in FIG. 17.
