Description
A WALL PANEL JOINT APPARATUS AND SYSTEM USING SAME
TECHNICAL FIELD
[0001] The present invention relates to wall panel joints and systems for wall panel application.
BACKGROUND INFORMATION
TECHNICAL FIELD
[0001] The present invention relates to wall panel joints and systems for wall panel application.
BACKGROUND INFORMATION
[0002] Architectural panel has been in use for many years. All architectural panel systems can be classified into two major categories, namely, "face- sealed" and "vented rainscreen" systems.
[0003] Face sealed systems include all systems with joinery that make use of sealant in the joinery whereby the system is substantially nonpermeable to either water or air. Achieving complete face seal is the very basis of all face seal systems. Sealant can be caulking, gasket, or other sealant of similar function. However, the lack of permeability/venting to either water vapor or air makes this system problematic.
[0004] On the contrary, vented rainscreen systems are designed to allow for permeability through the joinery, known as vents. The vent allow for breathability and rapid pressure equalization within the system cavity. However, these systems allow water to penetrate, causing water damage which is also problematic.
[0005] Accordingly, there is a need for architectural panel system that is both impermeable to water and permeable to air and water vapor.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0027] Referring first to FIG. l, one embodiment of the single compartment vertical joint 42 of the present invention is shown. The vertical joint 42 includes a single perimeter clip body 10, which, in one embodiment, is made from aluminum, but in other embodiments, is made from any metal or combination of metals. In the embodiment shown, the single perimeter clip body 10 is made from two identical extruded parts, and are brought together by the filler strip 12. However, in other embodiments, a single extrusion forms the perimeter clip body and filler strip structure.
[0028] The single perimeter clip body 10 is shown having one shape, but can be any other shape necessary for the function. In the preferred embodiment, the single perimeter clip body 10 is mitered at all corners. A filler strip 12 is inserted into the perimeter clip body 10, forming the wall cavity 20. However, in other embodiments, the single perimeter clip body 10 is a single extrusion and thus, the filler strip is not required. The filler strip 12 can be made from the same materials as the wall panels 14, the single perimeter clip body 10, or a different material from either or both. In one embodiment, the filler strip 12 is made from the same material as the wall panels 14. The filler strip can be homogenous or a composite.
[0029] In the preferred embodiment, the single perimeter clip body 10 includes at least one vent.
In the embodiment shown in FIG. l, two vents 16, 18 are shown. The vents 16, 18 allow escape from the wall cavity 20. Additionally, a pocket 24 is formed between the filler strip 12 and the single perimeter clip body 10. This pocket 24 is designed for ventilation and thermal movement.
This pocket 24 allows for pressure equalization and permeability through impermeable material.

This pocket 24 allows for pressure equalization and permeability through impermeable material.
[0030] The single perimeter clip body 10 holds at least two wall panels 14.
The single perimeter clip body 10 is not fixedly attached to the wall panels 14, rather, the clip body 10 is a floating clip, holding the wall panels 14 together without fasteners. However, in other embodiments, the single perimeter clip body 10 can be fastened to the wall panels 14.

[0031] Referring now to FIG. 2, one embodiment of the single compartment horizontal joint 40 is shown. The perimeter clip body 10 is the same as the perimeter clip body of the vertical joint (shown as 10 in FIG. 1). The horizontal joint also includes a rainscreen clip 22, which is a "J"
clip-like structure. The rainscreen clip 22 floats on the perimeter clip body 10 to allow for free movement in response to thermal expansion. The rainscreen clip 22 is made from the same s material as the clip body 10. In other embodiments, the horizontal joint 40 and rainscreen clip 22 structure are formed of a single extrusion.
clip-like structure. The rainscreen clip 22 floats on the perimeter clip body 10 to allow for free movement in response to thermal expansion. The rainscreen clip 22 is made from the same s material as the clip body 10. In other embodiments, the horizontal joint 40 and rainscreen clip 22 structure are formed of a single extrusion.
[0032] The rainscreen clip 22 attaches to a wall securing device 26 through any means for attachment. In the exemplary embodiment, the means for attachment is a zinc coated screw 28.
However, in other embodiments, any other type of screw or other equivalent means for attaching the rainscreen clip 22 to a wall securing device 26 can be used.
However, in other embodiments, any other type of screw or other equivalent means for attaching the rainscreen clip 22 to a wall securing device 26 can be used.
[0033] In one embodiment, the wall securing device 26 is a subgirt. The wall securing device 26 is attached to the wall 30 and secures the horizontal clip body 10 to the wall structure 30 by connecting the rainscreen clip 22 to the wall securing device 26. Although in the exemplary embodiment, the wall securing device 26 is a subgirt, in other embodiments, any device capable of securing the horizontal joint 40 to the wall 30 can be used.
[0034] Although the terms "horizontal" and "vertical" are used herein, the terms are merely used for distinction purposes. In some embodiments (and described in more detail below), the horizontal joint can be used in both the horizontal and vertical joint in the system. Following, both vertical and horizontal joints can be attached to a wall securing device.
When the horizontal joints are used as both the vertical and horizontal joints in the system, the horizontal joint is thus representative of both joints in the system.
When the horizontal joints are used as both the vertical and horizontal joints in the system, the horizontal joint is thus representative of both joints in the system.
[0035] Referring now to FIGS. 3 and 4, a section view of the double compartment joints are shown. Similar to the single compartment joints shown in FIGS. 1 and 2, the double compartment joints each include a perimeter clip body 52. The perimeter clip bodies of FIGS. 3 and 4 are the preferred embodiment shape.
[0036] The perimeter clip body 52 can either be a solid extrusion (which would include the filler strip structures as part of the single extrusion as well as the rainscreen clip, with respect to the horizontal joint, shown in FIG. 4) or, can be as shown in FIGS. 3 and 4.
Referring again to FIGS. 3 and 4, the perimeter clip body 52 is made form two identical extrusions, and they are connected by the filler strips 58, 60. The perimeter clip body 52 includes at least two vents 54, 56 as well as two divider filler strips 58, 60. The vents 54, 56 allow escape from the wall cavity 20. As described above with reference to FIGS. 1 and 2, the filler strips can be made of any material. Alternately, the joint can be a single extrusion, therefore not including filler strips.
Referring again to FIGS. 3 and 4, the perimeter clip body 52 is made form two identical extrusions, and they are connected by the filler strips 58, 60. The perimeter clip body 52 includes at least two vents 54, 56 as well as two divider filler strips 58, 60. The vents 54, 56 allow escape from the wall cavity 20. As described above with reference to FIGS. 1 and 2, the filler strips can be made of any material. Alternately, the joint can be a single extrusion, therefore not including filler strips.
[0037] A pocket 62 is formed between each end of the filler strips 58, 60 and the perimeter clip body 52. This pocket 62 is designed for ventilation and thermal movement.
These pockets 60 allows for pressure equalization and permeability through impermeable material.
These pockets 60 allows for pressure equalization and permeability through impermeable material.
[0038] Referring now to FIG. 6, the vertical joint shown in FIG. 3 is shown along with an illustration of the flow of air through the joint. The arrows represent the air. The air is blasted against the wall panels 14 and enters the system and joint through wall cavity 20. Vents 54, 56 provide an escape for the air. The air enters the vertical joint and flows around the filler strip 58 and into the compartment. The pocket 62 allows the air to flow through to the filler strip 60.
The pocket 62 forces the air to escape the compartment.
The pocket 62 forces the air to escape the compartment.
[0039] In practice, kinetic energy (wind) will increase the air pressure within the compartment until it equals the applied wind pressure. When the pressures are equal, water cannot enter the compartment. This state is attained quickly. Thus, the joints allow the system (described below) to attain optimal ventilation within the system, but prevent and minimize water entry. The joints shown in FIG. 3 and 4 include a number of mechanisms that both promote ventilation and prevent water from reaching the architectural structure wall (shown as 90 in FIG. 6).
[0040] Inner flanges A 64 and inner flanges B 66 sit at a range of 0°
to 90° from the filler strips 60,58. In the exemplary embodiment, flanges A 64 sit at 10° and flanges B sit at 10°. In other embodiments, the flanges sit anywhere from 0° to 90° from the filler strips 60,58.
to 90° from the filler strips 60,58. In the exemplary embodiment, flanges A 64 sit at 10° and flanges B sit at 10°. In other embodiments, the flanges sit anywhere from 0° to 90° from the filler strips 60,58.
[0041] The perimeter clip body 52 shown in FIG. 3 is the same as the perimeter clip body 52 shown in FIG. 4. Referring now to only FIG. 4, the addition of the rainscreen 70 modifies the vertical joint with one compartment into a horizontal joint with two compartments. In alternate embodiments, the horizontal joint shown in FIG. 4 can be one solid extrusion, rather than made by combining the perimeter clip body 52 with the rainscreen 70. In still other embodiments, the perimeter clip body is shaped differently, but has at least two compartments.
[0042] Similar to the joint described in FIG. 2, the horizontal joint attaches to a wall securing device 26 by a means for attachment 28. This attaches the horizontal joint to the wall 30.
[0043] The length and width of the joints will vary depending on the architectural structure in which they are being used to hold wall panels. Thus, the joints can be any length or width desired. Although not shown in the exemplary embodiment, the perimeter clip body can have more than two compartments. Referring now to FIGS. 7 and 8, a third filler strip 98 has been added to the embodiments shown in FIGS. 3 and 4, respectively.
