Description

The present invention related to a device used in the construction of buildings, particularly buildings comprising a double skin wall.

Background to the Invention Modern buildings are often constructed with a double skin wall, particularly buildings constructed using a timber frame kit. In a timber frame kit construction, there is an inner leaf made from sheeted timber and a brick outer leaf. The cavity between the leaves provides insulation for the building.

Over time buildings are known to settle. If the leaves of the double skin wall are of different materials, as is the case in a timber frame kit wall, one of the leaves can settle more than the other leaf. Differing settlement of the leaves of the construction can cause problems if, for example, a conduit carrying a service such as gas or water passes through the wall. If the settlement is severe it has been known for services conduits to be fractured during the settlement.

Brief Description of the Drawings Embodiments of the present invention will now be described with reference to the accompanying drawings in which: Figure 1 is a perspective, exploded view of a device for facilitating the passage of a services conduit through a double skin wall according to a first embodiment of the present invention; Figure 2 is a top, exploded view of the device of Figure 1; Figure 3 is a top section view of the device of Figure 1 shown in use; Figure 4 is a front view of the device shown in Figure 3 with the inner leaf of the outer skin wall removed; Figure 5 is a top view of a device for facilitating the passage of a services conduit through a double skin wall according to a second embodiment of the present invention; and Figure 6 is an end view of part of the device of Figure 5.

IgG Ο 6 10 Detailed Description of the Drawings Reference is firstly made to Figure 1, a perspective, exploded view of a device, generally indicated by reference numeral 10, for facilitating the passage of a services conduit through a double skin wall, according to a first embodiment of the present invention, and Figure 2, a top, exploded view of the device 10.

The device 10 comprises a first member 12 adapted to be associated with a first skin of a double skin wall and a second member 14 adapted to be associated with the second skin of a double skin wall.

The first member 12 defines a first aperture 16 which is in communication with a cylindrical passage 18 which extends from a rear surface 20 of the first member. The passage 18 and the aperture 16 are adapted to receive a services conduit (not shown) and allow passage of the services conduit through the first member 12.

The first member also includes a rubber strip seal 22 which surrounds the aperture 16.

The second member 14 defines a slot shaped aperture 24 also adapted to permit the passage of a services conduit therethrough. The second member 14 also defines a pair of backwardly depending wings 26,28 into which the first member 12 can be slid, the wings 26,28 restraining the first member 12 such that the first member 12 is only permitted to slide unidirectionally with respect to the second member 14 in the direction of arrows A (see Figure 1).

The second member 14 further comprises fixing holes 30 to permit the device 10 to be attached to the second skin of a double skin wall.

The arrangement of the device 10 in use will now be described with reference to Figures 3 and 4. Referring firstly to Figure 3, it can be seen that the first member passage 18 passes through the outer skin 40 of a double skin wall 42. The second member 14 is attached by means of fixings 32 to the inner skin 44 of the double skin wall 42. The fixings 32 engage and attach to the second member apertures 30.

The first member 12 is restrained against the rear surface 34 of the second member 14 by the wings 26,28 which are biased to press against the first member rear surface 20. The pressing action of the wings 26,28 engages the strip seal 22 (not visible in Figure 3) with the second member rear surface 34 forming a seal between, the first and second members 12,14.

Once the device 10 is located as shown in Figure 3, a services conduit 50, in this example a gas pipe, can be passed through the device 10 and the wall 42 from the exterior 60 to the interior 62 of the wall 42. As the external diameter of the gas pipe 50 is only slightly smaller than the internal diameter of the tubular passage 18 (the gas pipe 50 is shown in broken outline passing through the passage 18) the gas pipe 50 is effectively fixed relative to the first member 12 in a direction perpendicular to the axis of both the gas pipe 50 and the passage 18. In particular in the permitted direction of movement of the first member 12 with respect to the second member 14 (that is in the direction of arrows “A” on Figure 1) Referring particularly to Figure 4, a front view of the device 10 shown located in a wall 42, with the inner leaf 44 removed, as the wall 42 settles, relative movement of the outer leaf 40 with respect to the inner leaf 44 can be accommodated without stress being applied to the gas pipe 50. As the no η leaves 40,44 settle, the first member 12 and the services conduit 50 will move relative to the second member 14, within the oval slot 24 defined by the second member 14, in the directions of arrows “A”.

The seal formed between the first and second members 12,14 by the strip seal 22 (shown in broken outline on Figure 4) prevents any leakage of gas from the pipe 50 entering the cavity 64 (Figure 3) between the inner and outer leaves 40,44. This prevents any build up of gas in the cavity 64.

Reference is now made to Figure 5, a top view of a device 110 for facilitating the passage of a services conduit through a double skin wall according to a second embodiment of the present invention. The device 110 is similar in many respects to the device 10 of the first embodiment with the exception that first member passage 118 is adjustable in length. The passage 118 comprises a first portion 190 and a second portion 192 arranged in a telescopic relationship. The telescopic adjustment facilitates the device 110 accommodating skins 180 of different thicknesses. The passage 118 is cylindrical in section and includes an external flange 182. The flange 182 facilitates attachment of device 110, and particularly the passage second portion 192 to the wall skin 180.

The passage 118 also includes a shroud 186 through which the services conduit 150 passes. Best seen in Figure 6, the shroud 186 is rubber and defines a slot 188 to allow passage of the services conduit 150. The shroud 186 grips the conduit 150 ensuring a neat appearance and providing a barrier to prevent the ingress of dirt or animals into the wall cavity 164.

Various modifications and improvements made be made to the above described embodiment without departing from the scope of the invention. For Ιι example, a curtain could be provided across the second member aperture to improve the appearance of the device. 6 δ ;
