This invention relates in general to cladding ties.
The use of continuous insulation is mandated for some climates in the United States by newer energy codes. The purpose of continuous insulation is to eliminate thermal breaks that reduce thermal efficiency of insulation placed between framing members such as wall studs.
One efficient and technically sound exterior wall assembly that can function in all climates without any theoretical potential for condensation is a wall assembly in which rigid insulation boards or foam are placed outside of an air barrier (AB)/weather-resistive barrier (WRB) (i.e., within the wall drainage cavity). Such a wall assembly is often referred to as a “work everywhere wall.” The use of continuous insulation in such a wall assembly requires the use of frequently placed conventional ties to connect the wall cladding (i.e., paneling, masonry, or other types of cladding) to the backup wall. The function of these ties is to transfer lateral loads such as wind loads from the cladding to the back-up wall which acts as the structural support for the cladding.
In most masonry assemblies, metal masonry ties need to be installed at 16 inches on center in horizontal and vertical directions to meet building code requirements. These metal ties pass through the continuous insulation and result in thermal breaks that reduce the efficiency of the continuous insulation.
Many commercially available metal ties are made using galvanized steel. When such ties are integrated into the wall assembly, they cannot be replaced without removal of the masonry veneer. The life expectancy of masonry veneer is anticipated to be more than 70 years. During the life cycle of steel masonry ties, they are exposed to the environment within the wall cavity which is constantly moist. This environment and damage to the galvanizing layer caused during installation can cause corrosion of the metal ties. In some cases, structural collapse of the masonry veneer due to corrosion of metal ties has been documented.
When using continuous insulation, the differential temperature between the cladding materials and the back-up wall construction is increased. This temperature differential, along with other factors such as moisture related volume changes, can lead to significant in-plane differential movements between the cladding material and the back-up construction.
The present inventor recognized the need for an improved cladding tie that reduces thermal bridging where the ties penetrate the continuous insulation. The present inventor recognized the need for an improved cladding tie that is less susceptible to deterioration by moisture and weather conditions.
Cladding can move differentially from a back-up wall due to a number of reasons, such as thermal movements, movements caused by moisture expansion of cladding, differential structural movements between the back-up wall and the cladding wall, and seismic movements. The present inventor recognized the need for a cladding attachment device that can accommodate in-plane differential movements between the cladding material and the back-up wall construction.
The present inventor recognized the need for a cladding attachment device that would be easy to install. The present inventor recognized the need for a cladding attachment device that can be efficiently installed in such a manner that the accommodated in-plane differential movements can be in any in-plane direction without a need to set a starting point of movement in the attachment device.
When installing continuous insulation panels, the panels are often installed in complete contact with the AB/WRB on the back-up surface. This prevents proper drainage of water on the exterior face of the AB/WRB. Water can be trapped in the minute gap between the continuous insulation and AB/WRB due to capillary action. This trapped water can cause accelerated deterioration of ties and other components.
The present inventor recognized the need for an improved cladding tie that creates a gap between the continuous insulation panels and AB/WRB. This gap facilitates drainage.
Conventional cladding ties do not provide any mechanism for ensuring that the continuous insulation panels are held in place. As such, continuous insulation panels are often installed with adhesive backing to ensure they stay in place. This adhesive backing can impede drainage of water on the drainage plane and can degrade and fail over time under certain circumstances. This adhesive backing will also results in additional labor and material costs.
The present inventor recognized the need for a cladding tie that can retain the continuous insulation panels in place and eliminate the need of reliance on adhesive backing.
Certain building codes restrict the length of conventional metal ties to 4 inches because longer length conventional ties are susceptible to buckling under compressive load. The present inventor recognized the need to transfer some compressive force from the cladding tie onto the insulation to reduce or eliminate the possibility of buckling under compressive loads and to reduce the effective span of the tie shaft within the cavity.
A cladding tie for providing a support connection between a cladding wall and a backup wall is disclosed. The cladding tie comprises a base and a retainer assembly.
In some embodiments, the cladding tie permits differential in-plane movement between the cladding wall and the backup wall. Any movement in-plane is allowed within a predefined range.
In one embodiment, the retainer assembly comprises a cladding connection member, a retainer member. The base comprises a shaft and a back plate. The shaft extends from the back plate. The shaft comprises a plurality of teeth. The cladding connection member comprises a cladding attachment surface and a retainer connection portion.
The retainer member comprises an insulation contact surface, a receiving channel, a cladding connection member recess, and a locking arm. The receiving channel comprises a receiving entrance on the insulation contact surface. The receiving channel extends transversely through the insulation contact surface and is configured to receive the shaft. The locking arm is adjacent the receiving channel. The locking arm is biased to a locked position where the locking arm engages at least one of the plurality of shaft teeth when the at least one of the plurality of shaft teeth is adjacent the locking arm to prevent the retainer member from moving in a first direction away from the back plate.
The retainer connection portion is moveable within the cladding connection member recess to permit differential movement between the cladding connection member and the retainer when the cladding connection member is connected to the retainer.
The retainer member is configured to hold an insulation panel against the back plate when the retainer member in a holding position along the shaft.
In some embodiments, a resilient biasing member is provided. The biasing member is located in the cladding connection member recess to buffer contact between the cladding connection member and the retainer. The biasing member also biases the cladding connection member a centered position. This centering feature ensures that the ability of the cladding tie to allow differential in-plane movements is maintained in all directions after installation.
In some embodiments, the cladding connection member comprises a cladding attachment surface and a retainer connection portion. The retainer connection portion is recessed from the cladding attachment surface. The retainer contact surface is recessed to a depth so that the retainer does not protrude beyond the cladding attachment surface when the retainer assembly is assembled.
In some embodiments, the cladding connection member comprises a vertical arm and a horizontal arm. The horizontal arm comprises a plurality of corrugations for interlocking with mortar of a masonry join of the vertical cladding wall. The vertical arm is moveable within the cladding connection member recess to permit differential movement between the cladding connection member and the retainer when the cladding connection member is connected to the retainer.
Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims, and from the accompanying drawings.
The following description is presented to enable any person skilled in the art to make and use the invention. For the purposes of explanation, specific nomenclature is set forth to provide a plural understanding of the present invention. While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.
The base 102 has a back plate 106 and a shaft 112 extending from the back plate. In some embodiments, the shaft extends perpendicular from the back plate. The shaft 112 has a blank portion 118, a toothed section 114, and an end portion 120. The blank portion 118 is adjacent the back plate 106.
Adjacent the blank portion 118 opposite the back plate is the toothed section 114. The length of the blank portion 118 may depend on the desire thickness of the insulation panels 52 of a given application. The toothed section 114 has a plurality of shaft teeth 113 adjacent recesses 113c. On opposite lateral sides of the toothed section are shoulders 116. The shoulders 116 provide improved rigidity in the vertical direction in resistance against buckling under compressive load. In addition, the shoulders 116 assist in alignment when the shaft is inserted in a receiving channel 142 of a retainer member 130 of the retainer assembly 104.
The teeth 113 comprise a vertical raised portion 113a intersecting an angled second portion 113b to form a peek as can best be seen from
Adjacent the toothed section 114 opposite the blank portion 118 on the shaft is the end portion 120. The end portion 120 may comprise tapered sides 120a (right side not shown). The tapered arrangement allows for easier insertion into the receiving channel 142 of the retainer member.
The back plate 106 comprises one or more fastening apertures 108. Multiple fastening apertures allow for increased variably in alignment with studs of the back-up wall. The fastening apertures may comprise countersunk recesses 110 is shown in
The back plate has a back surface 109. In some embodiments, the back surface may be concave. The concave arrangement provides that the entire perimeter 105, from the top, bottom, left, and right edges, of the back surface 109 is located closer to the straight plane 63, such as might be provided by the backup wall 53, as compared to the center 103.
Therefore, the back plate is continuously curved from the perimeter to the center 103. The back surface 109 is at least slightly concave. The concave or cupped arrangement provides for a more uniform pressure on the back-up wall surface when fastened to the back-up wall 53. This occurs because the pressure of the screws drawing the back plate against the backup wall surface causes the back surface 109 to flex and flatten against the backup wall surface. This can result in a more uniform pressure applied across the external surface, such as the backup wall surface, from the back plate.
The retainer assembly 104 comprises a retainer member 130, a rear plate 132, a spacer 134, and a cladding connection member or mount plate 136. The retainer member 130 comprises a receiving channel 142, a front face 160, a back side 161, a bottom side 162, a top side 164, a left side 166, and a right side 168.
The front face 160 comprises a central portion 170, a lower angled portion 172, an upper angled portion 174, a left side angled portion 176, and a right side angled portion 178. The angled portions 172, 174, 176, 178 are inclined from the respective sides 162, 164, 166, 168 to the central portion 170.
The back side 161, as shown in
The protruding portion 186 comprises a back surface 188, a top surface 190, a bottom surface 192, a left side surface 191, and a right side surface 193. The top surface 190 comprises a top elongated projection 194 extending along the top surface from the right side to the left side. The bottom surface 192 comprises a bottom elongated projection 196 extending along the bottom surface from the right side to the left side.
The channel 142 extends from the back surface 188 through the protruding portion and through the central portion 170 of the front face. The floor of the channel 142 comprises a plurality of raised portions or plateaus 140 and recesses 141.
The rear plate 132 comprises a front surface 200, a back surface 202, a bottom surface 204, a top surface 206, a left side 208, a right side 210, and a rear plate aperture 212. The aperture 212 comprises a lower surface 213 having a lower groove 214 and an upper surface 215 comprises an upper groove 216. The upper and lower grooves extend along the upper and lower surfaces, respectively, between the right and left sides 218, 220. In some embodiments, the exterior perimeter of the rear plate comprises a square, rectangle, quadrilateral, circle, ellipse or other shape.
The aperture 212 is sized so that the lower surface 213, upper surface 215, left side 220, and right side 218 are in surface-to-surface contact or in close proximity, as shown in
The spacer 134 comprises a front surface 222, a back surface 224, a bottom surface 226, a top surface 228, a left side 230, a right side 232, and a spacer aperture 234. The interior walls defining the spacer aperture are sized so they are in surface to surface contact or in close proximity to the corresponding to bottom surface 192, top surface 190, left side surface 191, and right side surface of the protruding portion 186. In some embodiments, the spacer aperture 234 comprises an area that is the same as an area of the rear plate aperture 212.
The mount plate 136 comprises a cladding attachment portion 236, a retainer connection portion 238, and a receiving opening 240. The retainer connection portion 238 is recessed from the cladding attachment portion 236. A curved transition 254 is provided between the retainer connection portion 238 and the cladding attachment portion 236. The cladding attachment portion 236 comprises an upper portion 242, a side portion 244, and a lower portion 246. The retainer connection portion 238 comprises an upper portion 248, a side portion 250, and a lower portion 252. The receiving channel is open to the left side.
The retainer assembly 104 is joined and provided against insulation panels 52 as shown in
Alternatively, the spacer 134 and the rear plate 132 may first be placed over the protruding portion 186 so that the protruding portion 186 is received through the spacer aperture 234 and into the rear plate aperture 212. The sides of the spacer aperture 234 are in contact with the sides of the protruding portion 186 as shown in
The mount plate 136 is then moved over the spacer 134 and protruding portion 186 of the retainer member 130 in the direction E of
In some embodiments, the spacer 134 comprises a flexible material, such as foam. The flexible material may be resilient, elastic, or otherwise returnable to a default expanded state after being compressed when not under a load above a predefined threshold. The flexible material of the spacer automatically self-centers the mount plate 136 about the spacer and protruding portion 186 during installation. This allows ease of installation in that the installer does not need to center the mount plate relative to the protruding portion, instead the installer places the mount plate in contact with or adjacent to the top surface 228, right side surface 232, and bottom surface 226 of the spacer. The spacer will appropriately position the mount plate relative to the protruding portion, the retainer member, and thereby relative to the shaft when the retainer member is mounted to the shaft. This centering feature ensures that the ability of the cladding tie to allow differential in-plane movements is allowed in all directions after installation.
Movement parallel to the cladding wall 50 or 326 or the front surface of cladding wall 50 or 326 is allowed by the slot 199. For example, movement of the mount plate 136 in one or more directions parallel to the cladding is allowed within the slot 199, which can permit differential movements between the cladding and backup wall.
The plane(s) of “in-plane” refer to any plane parallel to the cladding wall, such as the cladding wall 50 or 326 or the front surface of cladding wall 50 or 326. The slot 199 is parallel to the cladding 50 when deployed. Therefore in-plane movement is allowed within the plane of the slot 199. The slot 199 is sized to receive the retainer connection portion 238. The retainer connection portion 238 and the cladding attachment portion 236 of the mount plate 136 are each parallel to the cladding 50 when deployed. Therefore, in-plane movement is allowed within the plane of retainer connection portion 238 and the plane of the cladding attachment portion 236 when the retainer connection portion 238 is received in the slot 199. Further, a vertical arm 280 of a second embodiment cladding connection member 278 is parallel to the cladding 326 when deployed. The slot 199 is sized to receive the vertical arm 280 of the second embodiment cladding connection member 278. Therefore, in-plane movement is allowed in the plane of the vertical arm 280 when the vertical arm 280 is received in the slot 199.
Four directions, two vertical directions and two horizontal directions, of in-plane movement or movement parallel to the cladding are illustrated at the compass rose 138 in
The flexibility or collapsibility of the spacer allows movement of the mount plate 136 relative to the shaft 112, the retainer member 130, the rear plate 132, and the spacer 134 in any in-plane direction, such as, in the plane of the slot 199. Likewise, the flexibility of the spacer allows movement of the shaft 112, the retainer member 130, the rear plate 132, and the spacer 134 relative to the mount plate 136 in any in-plane direction, such as, in the plane of the slot 199.
Pressure from the mount plate or pressure between the mount plate and the protruding portion 186 can compress or crush one or more sides of the spacer to allow in-plane movement. Likewise, pressure transferred via the shaft and retainer can cause the one or more sides of the spacer to be compressed or crushed against the mount plate or between the mount plate and the protruding portion 186. The in-plane movement allowance enabled by the spacer permits differential movement between the cladding 50 and the backup wall 53 without destruction or impartment of the cladding tie, or cracking of the cladding material, while allowing transfer of wind load in the out-of-plane direction from the cladding through the shaft and base to the backup wall. Any movement in-plane is allowed within a predefined range. In one example, the predefined range of movement in a given in-plane direction is defined or limited by the extent and distance that the spacer can be compressed or crushed between the mount plate and the protruding portion 186.
Sections 181, 184, 182 of the back side 186 of the retainer member 130 contact the front surfaces of portions 248, 250, and 252, respectively, of the retainer connection portion 238 of the mount plate 136. Rear surfaces of portions 248, 250, and 252 contact the front surface 200 of the rear plate 132. The back surface 202 of the rear plate 132 contacts the front surface of the insulation panel 52.
Then the retainer member can be moved further in the direction D to increase compression on the insulation panel and the mount plate 136. In some embodiments and applications, the retainer member 130 provides a friction or compression grip on the mount plate 136 by pressure between the retainer member 130 and the rear plate 132 through the insulation panel and the back plate 106. The friction or compression grip prevents the mount plate 136 from becoming disconnected from the retainer assembly 104.
In some embodiments and applications, grip of the retainer on the mount plate 136 does not prevent the in-plane movement at the retainer connection portion 238 of the mount plate 136, explained above, to allow for in-plane differential movement of the cladding wall 50 relative to the backup wall and the shaft. In some embodiments, the retainer does not grip the mount plate 136, so as to allow in-plane movement of the mount plate 136. In some embodiments, the retainer and the rear plate are each adjacent or in surface-to-surface contact with the mount plate at the slot 199 to guide the in-plane movement of the mount plate and limit the movement of the mount plate to in-plane movements between the retainer and the rear plate in the slot 199.
In some embodiments, the spacer comprises a thickness that is the same, less than, or greater than the thickness of the retainer connection portion 238 of the mount plate 136. The receiving channel 142 of the retainer member 130 is configured, as shown in
The locking arm 146 is biased to extend into the receiving channel 142 in the direction C of
The locking arm teeth 148 can be disengaged from the shaft teeth 113 by pulling the locking arm 146 upward in the direction A of
The locking arm 146 does not need to be raised, to disengage the locking arm teeth 148 from the shaft teeth 113, in order to allow the retainer member 130 and retainer assembly 104 to move in direction D relative to the shaft. When the retainer member 130 is moved in direction D relative to the shaft 112, angled portions of the teeth 148 will slide along the angled second portions 113b of the shaft teeth 113 from one tooth to the next until the retainer member is no longer moved in direction B or the retainer member 130 and rear plate 132 meet an exterior surface, such as continuous insulation panels 52. In this way, the retainer member 130 can secure the continuous insulation panels 52 against the backup wall 53 and or the back plate 106 at least until the locking arm is moved in the direction A to release the locking arm teeth 148 from the shaft teeth 113. Therefore the locking arm 146 has a raised position in the direction A where the locking arm teeth 148 are disengaged from the shaft teeth 113 so that the retainer member can move in direction B. The locking arm 146 has a lowered or engaged position where the locking arm teeth 148 are engaged with the shaft teeth 113 so that the retainer member is prevented from moving in the direction B away from the back plate 106.
In some embodiments, the back surface 188 of the protruding portion of the retainer and the back surface 202 of the rear plate 132 may each be concave in the same manner described regarding back surface 109 of the back plate to provide for uniform compressive pressure against the rigid insulation panels 52. Therefore, when the retainer member is locked against the insulation panel(s), the central location of the receiving channel 142 and locking arm 146 lock the back plate against the backup wall surface causing the concave back surfaces 188, 202 to flex and flatten against the insulation panel if sufficient force is applied to the retainer member. This arrangement distributes the load across the insulation panel in the area where the retainer assembly contacts the insulation panel and reduces the chance that the insulation panel will be indented or crushed by the pressure applied to the retainer member. In some embodiments, only the back surface 202 is concave and the back surface 188 is not.
Cladding 50 is attached to the backup wall 53 via the ties 100. In some applications, the cladding 50 comprises a plurality of vertically extending panels 50a, 50b, 50c, 50d. The panels connect to adjacent panels (50a, 50b) (50b, 50c), (50c, 50d) at panel seams 55a, 55b, 55c, respectively. A cut away view of panels 50c and 50d are shown in detail in
As shown at panel seam 55c, the first side wall 59b of panel 59 is adjacent the second side wall 57c of the panel 57. The cladding connection projection 57e is received in the cladding connection recess 59d. A fastener 48 penetrates the cladding connection projection 57e into the mount plate 136. In some embodiments the fastener 48 penetrates both the cladding connection recess 59d and the cladding connection projection 57e at the intersection of the same, and into the mount plate 136. In some applications the fastener 48 may have a low-profile head so as not to interfere with the joining of the cladding connection recess and the cladding connection projection. In some applications, the cladding connection recess is sized to provide a friction fit with the cladding connection projection.
In some applications, the seam 55c and the fastener 48 is centered below the shaft 112 of the corresponding tie. In some applications, the seam 55c and the fastener 48 is located at any location on the cladding attachment portion 236 of the mount plate 136.
In some applications, the cladding comprises horizontally extending panels, which are joined to the ties with fasteners at the cladding attachment portion 236. In some applications, the cladding comprises a mix of horizontally and vertically extending panels. In some applications, the cladding panels are not attached at a cladding seam, but are instead attached at other locations of the panel such as in the middle or between cladding seams. In some applications, the cladding panels do not have substantial sidewalls, and the cladding panels mount flush against the mount plate 136.
The recess nature of the retainer connection portion 238 of the mount plate 136 allows the retainer member 130 to be recessed behind the rearmost surface of the cladding panels. Therefore, in some applications, the retainer member 130 does not protrude beyond the plane defined by the cladding attachment portion 236 and therefore does not interfere with the mounting and attachment of the cladding panels. Any number of ties may be placed between the cladding and the backup wall depending on the needs of a given application.
The retainer assembly 104 is capable of securing the insulation in place. In addition, the retainer assembly also transfers a portion of the compressive force from the cladding 50, under positive wind or other loads, to the insulation panels 52 via the shaft 112 connection with the cladding wall 50 and the retainer assembly 104. Such loads may also be transferred from the insulation panels to the backup wall 53. This load transfer from the cladding 50 to the insulation and/or the backup wall assist in the prevention of buckling of the shaft where the insulation thickness and/or cavity are large, such as where the cavity is more than 4 inches.
The connection member 278 comprises a vertical arm 280, and a horizontal arm 282. The vertical arm 280 is connected or formed with the horizontal arm at a corner 283. The horizontal arm comprises a first section 284 between a corrugated section 286 and the corner 283. The corrugated section comprises a plurality of ridges 288 and valleys 290. The valleys 290 create lowered portions 294 on a bottom side of the corrugated section. The ridges create recessed portions 292 on the bottom side of the corrugated section. In some embodiments, the distal end of the horizontal arm comprises an end ridge 296 of the plurality of ridges of the corrugated section.
The vertical arm 280 comprises a receiving opening 298 and a pair of lower arms 300, 302. The receiving opening 298 separates the lower arms. The receiving recess comprises a left side wall 304, a top wall 306, and a right side wall 307. The second embodiment spacer 276 comprise a spacer aperture 308, a front surface 309, a left side wall 310, a top wall 312, a right side wall 314, and a bottom wall.
The retainer member 130 and rear plate 132 are rotated ninety degrees clockwise from the position of first embodiment cladding tie 100. The base 102 is also rotated ninety degrees clockwise from the position of first embodiment cladding tie 100.
The base 102 of the tie 270 can be positioned on the backup wall 320 so that the corresponding shaft 112 will be located at a masonry joint 330 or seam. Then the masonry veneer wall 326 can be constructed so that at least a portion, if not all of the corrugated section 286 of the cladding connection member 278 is located in a mortar joint 330 between adjacent bricks or blocks as shown in
The retainer assembly 274 is joined and provided against insulation panels 52 as shown in
Alternatively, the spacer 276 and the rear plate 132 may first be placed over the protruding portion 186 so that the protruding portion 186 is received through the spacer aperture 308 and into the rear plate aperture 212. The sides of the spacer aperture 308 are in contact with the sides of the protruding portion 186. The grooves 214, 216 receive the elongated protrusions 194, 196. And then the retainer member, spacer, and back plate, together as a unit, is placed over the shaft so that that the shaft is received in the receiving channel 142. And the retainer member, spacer, and back plate, together as a unit, are moved adjacent to or in contact the insulation panel.
The cladding connection member 278 is then moved over the spacer 276 and protruding portion 186 of the retainer member 130 in the direction S of
In some embodiments, the spacer comprises a flexible or collapsible material, such as insulating foam. The flexible material may be elastic or otherwise returnable to a default expanded state after being compressed when not under a load above a predefined threshold. The flexible material of the spacer automatically centers the cladding connection member 278 about the spacer and protruding portion 186 during installation. This allows ease of installation in that the installer does not need to center the cladding connection member 278 relative to the protruding portion, instead the installer places the cladding connection member 278 in contact with or adjacent to the top wall 312, right side wall 314, and the left side wall 310 of the spacer. The spacer will appropriately position the cladding connection member 278 relative to the protruding portion, the retainer member, and thereby relative to the shaft when the retainer member is mounted to the shaft.
The flexibility or collapsibility of the spacer allows movement of the cladding connection member 278 relative to the shaft 112, the retainer member 130, the rear plate 132, and the spacer 276 in any in-plane direction, such as, in the plane of the slot 199. Likewise, the flexibility of the spacer allows movement of the shaft 112, the retainer member 130, the rear plate 132, and the spacer 134 relative to the cladding connection member 278 in any in-plane direction, such as, in the plane of the slot 199.
Pressure from the cladding connection member 278 or pressure between the cladding connection member 278 and the protruding portion 186 can compress or crush one or more sides of the spacer to allow in-plane movement. Likewise, pressure transferred via the shaft and retainer can cause the one or more sides of the spacer to be compressed or crushed against the cladding connection member 278 or between the cladding connection member 278 and the protruding portion 186. The in-plane movement allowance enabled by the spacer permits differential movement between the cladding 326 and the backup wall 320 without destruction or impartment of the cladding tie, or the cladding system. Four directions, two vertical directions and two horizontal directions, of in-plane movement are illustrated at the compass rose 272. Any intermediate direction of in-plane movement or movement parallel to the cladding, between the four directions illustrated, is also possible. Therefore, any combination of vertical and horizontal moment is possible in-plane. Any movement in-plane is allowed within a predefined range. In one example, the predefined range of movement in a given in-plane direction is defined or limited by the extent and distance that the spacer can be compressed or crushed between cladding connection member 278 and the protruding portion 186.
Sections 181, 182, 184 of the back side 186 of the retainer member 130 contact the front surface of the vertical arm 280. The rear surface of the vertical arm contacts the front surface 200 of the rear plate 132. The rear surface 200 of the rear plate 132 contacts the front surface of the insulation panel 52.
Then the retainer member 130 can be moved further toward the back plate 106 to increase compression on the insulation panel and the connection member 278. In some embodiments and applications, the retainer member 130 provides a friction or compression grip on the cladding connection member 278 by pressure between the retainer member 130 and the rear plate 132 through the insulation panel and the back plate 106. The friction or compression grip prevents the mounting member from becoming disconnected from the retainer assembly 274. The retainer member is engagable and releasable with the shaft in the same manner as described regarding tie 100. The tie 270 may be used in other masonry veneer wall applications, such a veneer walls comprising brick, stone, block, or the like.
In some embodiments and applications, the grip of the retainer on the connection member 278 does not prevent the in-plane movement at the vertical arm 280 of the connection member 278, as explained above, to allow for in-plane differential movement of the masonry wall 326 relative to the backup wall and the shaft. In some embodiments, the retainer does not grip the connection member 278 so as to allow in-plane movement of the connection member 278. In some embodiments, the retainer is adjacent or in surface-to-surface contact with the cladding connection member 278.
The protruding portion 353 of the retainer member 340 comprises a right side 351, a top side 253, a left side 357, and a bottom side 359. Each such side comprises a spring set 346, 350, 348, 352. As each spring set is identical so only spring set 346 will be described. Spring set 346 comprises a first spring 354 and a second spring 356. The first spring is mirror image identical to the second spring about the valley 358. The first spring comprises a peak 360 and a recessed end 362. The peak is farther away from the protruding portion 353 than the valley 358 or the recessed end 362. The recessed end's inward position helps prevent it from binding on the walls of the retainer connection portion 238 or the receiving opening 298 of the connection member 278. Each spring is biased away from the protruding portion, such that when the spring is compressed toward the respective wall of the protruding portion, the spring will create tension biased toward the home, uncompressed position, such as shown in
The springs achieve the same or similar functions as the flexible or collapsible material of the spacers 134, 276. The springs automatically center the mount plate 136 about the protruding portion 353. This allows ease of installation in that the installer does not need to center the mount plate relative to the protruding portion, instead the installer places the mount plate in contact with or adjacent to the spring sets 350, 346, 348.
The flexibility of springs allow movement of the mount plate 136 relative to the shaft 112, the retainer member 340, and the rear plate 132 in any in-plane direction in the plane of the retainer connection portion 238 between the rear plate 132 and the retainer member 340. Likewise, the flexibility of the springs allow movement of the shaft 112, the retainer member 340, and the rear plate 132 relative to the mount plate 136 in any in-plane direction in the plane of the retainer connection portion 238 between the rear plate 132 and the retainer member 340. Therefore, the mount plate can compress one or more spring about the protruding portion 353 to allow in-plane movement. The in-plane movement allowance enabled by the springs permit differential movement between the cladding 50 and the backup wall 53 without destruction or impartment of the cladding tie.
Likewise, the springs automatically center the cladding connection member 278 about the protruding portion 353. This allows ease of installation in that the installer does not need to center the cladding connection member 278 relative to the protruding portion, instead the installer places the cladding connection member 278 in contact with or adjacent to the spring sets 346, 350, 348. The springs allow movement of the cladding connection member 278 relative to the shaft 112, the retainer member 130, and the rear plate 132, in any in-plane direction in the plane of the vertical arm 280 between the rear plate 132 and the retainer member 340. Likewise, the springs allow movement of the shaft 112, the retainer member 130, and the rear plate 132 relative to the cladding connection member 278 in any in-plane direction in the plane of vertical arm 280 between the rear plate 132 and the retainer member 340. Therefore, the cladding connection member 278 can compress one or more springs about the protruding portion 353 to allow in-plane movement. The in-plane movement allowance enabled by the springs permit differential movement between the cladding 236 and the backup wall 320 without destruction or impairment of the cladding tie.
While
In some embodiments, the rear plate 132 is integrally formed as one unit with the retainer member 130 at the protruding portion 186 in the position shown in
While cladding connection members 136 and 278 are shown, it will be appreciated that other types and shapes of members for connecting cladding to the retainer member can be used.
From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
