Description

Retaining Clip The invention relates to a retaining clip for connecting a wall tie to a timber frame or the like. More specifically, the invention relates to a retaining clip for connecting a wall tie to an insulated timber frame and a method of connecting a wall tie to an insulated timber frame. The invention further relates to a kit for constructing an insulated timber frame.
In timber framed buildings and construction, external masonry, sometimes otherwise referred to as block work, is provided as a weather screen to the timber frame. As forces, such as those from wind pressure experienced by the construction, are applied to the block work/timber frame assembly, the block work maybe pulled in or pushed away from the timber frame.
Typically, wall ties are provided to retain the timber frame and the external block work in position relative to one another and to provide resistance to the affects of forces and pressures applied to the assembly.
Changes to building regulations and a drive for greater carbon efficiency are generating a need to increase the thermal envelope in construction. There is an increasing need to insulate the timber frame/external block work assembly, however, this leads to difficulties in locating the insulation around the existing assembly of wall ties) timber frame and external block work.
It is an aim of the present invention to overcome the difficulties associated with providing an insulated timber frame and connecting same to external block work whilst maintaining the resistance of the assembly to external forces acting to separate the frame and the block work.
It is a further aim of the present invention to provide a retaining dip capable of improving the connection of a wall tie to an insubted timber frame.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood that the drawings and
B
detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
Further) although the invention will be described in terms of specific embodiments) it will be understood that various elements of the specific embodiments of the invention will be applicable to all embodiments disclosed herein.
In the drawings) similar features are denoted by the same reference signs throughout.
Reference is initially made to Figures 1 of the drawings which illustrates a retaining clip 1 formed of planar, stainless steel and having a square, planar body portion 2. A receiving portion 4 is provided by a raised rib 6 pressed from the material of the body portion 2. The raised rib 6 surrounds receiving portion 4 and is operable to receive and retain the end portion of a wall tie (not shown) and to prevent movement of same relative to the retaining clip 1 when the wall tie and the retaining clip and fastener together. Fastener aperture B is located centrally of the receiving portion 4. A fastener (not shown) can be passed through the end portion of the wall tie (not shown) and the fastener aperture B into a timber frame (see Figure 9).
Figure 2 illustrates an alternative retaining clip 10. Retaining clip 10 differs from retaining clip 1 in that raised rib 16 is discontinuous about the receiving portion 4 of the retaining clip 10. As with raised rib 6) rib 16 is embossed from the material of the body portion 2 of the retaining clip 10. The raised rib 16 prevents upward and sideways movement of the end portion of a wall tie (not shown] when same is received and retained in receiving portion 4.
Figure 3 depicts a retaining clip 20 which differs from retaining clip 10 in that the body portion 22 is a planar) stainless steel and having a circular, planar body portion 22. It will be understood that the raised rib 16 of retaining clip 20 could, alternatively, be replaced by the raised rib 6 of Figure 1.
The retaining clip 30 of Figure 4 differs from retaining clip 20 of Figure 2 in that it is formed of planar, plastic and having a square, planar body portion 32. The receiving portion 4 of retaining clip 30 is bounded on three sides by a cut out 36 in the material of the body portion. It will be understood that the discontinuous cut out portion 36 of retaining clip 30 could, alternatively, be replaced by a continuous cut out portion configured in the same way as the raised rib 6 of Figure 1.
Figure 5 depicts and alternative retaining clip 40. Although in the depicted embodiment, the retaining clip 40 is formed of planar, stainless steel having a circular, planar body portion 42, the body portion 42 maybe of square or any other footprint whatsoever., Further, the raised rib 46 is discontinuous about receiving portion 4, although in alternative embodiments, the raised rib 46 maybe continuous about receiving portion 4 thereby surrounding the receiving portion.
Recess 49 is provide in the body portion 42. The recess 49 is a slot or slit cut in the material of the body portion 42 between the edge of the body portion 42 and the raised rib 46. The recess 49 passes through fastener aperture 48. The use of retaining clip 40, the recess 49 is initially widened by pulling the material of the clip apart The retaining clip 40 may then be passed over an elongate portion of a wall tie (not shown) and the pulling force on the material of the clip released. In this way, the material of the body portion 42 closes about the elongate portion of the wall tie so as to receive and retain same in connection with clip 40. The retaining clip 40 may then be locked in place over the wall tie to prevent accidental separation of the assembly.
Figure 6 illustrates retaining clip 40 of Figure S with the end portion 51 of a wall tie attached thereto. The elongate portion of the wall tie is passed through slot 49 until it is ocated in receiving portIon 4 of the clip 40. Once located in the receiving portion 4, the slot 49 is allowed to dose about the wafi tie and a fastener (not shown) is passed through fastener aperture 48 to attach the clip 40 to an insulating panel [not shown). The clip may be rotated through 90 degrees before the fastener is attached so as to lock the wall tie in place.
Figure 7a shows the retaining clip 40 of Figure 5 with the end portion 51 of a wall tie connected thereto. The end portion 51 of the wall tie is received in receiving portion 4 by pushing the retaining clip 40 onto the wall tie. The tie is retained in position by the embossed rib 46 surrounding receiving portion 4 on three sides.
The embossed rib 46 prevents upwards and sideways movement of the end portion 51 of the wall tie when same is located in the receiving portion 4.
Figure 7b shows the end portion Si of the wall tie depicted in Figure 7a. Elongate portion 53 of the wall tie extends away from the end portion 51 towards a further end portion (not shown). The further end portion, in use of the wall tie, is connected to the block work or masonry ofan external wall.
Figure 8 shows an insulated timber frame 100 connected to the retaining clip 40 of Figure 6 with a wall tie 105 received and retained by the retaining clip 40. During assembly of the insulated timber frame 100, the end portion 51 of wall tie 105 is fixed to the timber frame 107 by bearing onto and being nailed with fastener 59 through the oriented strand board face 103 of the timber frame 107. Rigid insulation in the form of panel 101 is fixed around the tie 105 during the assembly process with the retaining clip 40 being fixed over the tie 105 to hold the insulation panel 101 in place. The additional surface area provided by the body portion of the retaining clip relative to the surface area of the end portion 51 of the wall tie 105 allows the forces applied to the timber frame 107 to be dispersed over the surface area of the insulation panel 101 against the body portion of clip 40 thus preventing the wall tie from being pulled through the insulation panel 101.
The elongate portion 53 of wall tie 105 extends away from end portion 51 towards a further end portion (not shown), which further end portion is connected to an external wall.
Figure 9 shows an insulated timber frame 200 connected to a retaining clip (1, 10, 20, 30, 40] with the end portion 51 of a wall tie 105 received and retained by the retaining clip. In this alternative arrangement) during assembly of the insulated timber frame 200, the end portion 51 of wall tie 105 is fixed to the face of a rigid insulation panel 101 by fastener 59. Fastener 59 passes through the fastener aperture 8 of the retaining clip, through the end portion 51 of the wall tie, through the oriented strand board face 103 of the timber frame 107. The additional surface area provided by the body portion of the retaining clip acts as a spreader plate to spread the compression load applied by forces acting on the wall tie over a larger surface area than is provided by the surface area of the end portion 51 of the wall tie 105.
