Abstract
A building component, for example a window frame member, comprises an inner structural member (10) and an outer structural member (12), each structural member (10, 12) having one part of a two part fastening (14, 16). The part (14) on the inner member (10) is a tenon, and the part (16) on the outer member (12) is a formation (18) providing a mortise for location of the corresponding tenon. The formation (18) is of channel shape having splayed apart limbs (20) which are movable from a splayed attitude to a substantially parallel attitude against the side of the tenon, and means (22, 28) to prevent subsequent movement between the members (10, 12).
Description
2350642 A METHOD OF FORMING A BUILDING COMPONENT FROM DIFFERENT MATERIALS
This invention relates to a method of forming a building component, particularly but not exclusively a structural member for a window frame, from different materials, such as a metallic material, for example aluminium, and a wooden or plastic material. In window construction, (1) frames all of wood have been provided, (2) frames all of plastics have been provided, (3) and frames all of aluminium have been provided. Each of these frames has disadvantages. The all-wood frames have a problem in that at least the external parts required regular maintenance and upkeep to prevent the wood rotting. The plastic frames can discolour through weathering and cannot be painted without the paint peeling off due to the characteristics of the plastic material and weathering. The aluminium frames have durability however suffer from cold-bridging with air condensing on the inside of the window frames and a higher cost than the others.
An object of the present invention is to provide a building component from a composite of materials which obviates or mitigates the aforesaid disadvantages.
Accordingly, one aspect of the present invention is a method of forming a building component comprising providing an inner structural member of non temperature conducting material and an outer structural member of metallic material, providing each structural member with one part of a two part fastening, the part of the inner member being a tenon, and the part on the outer member being a formation providing a mortise. for location of the corresponding tenon, the formation being of channel shape having splayed apart limbs, bringing the two members together with the tenon located in the mortise, causing the limbs to be moved from a splayed attitude to a substantially parallel attitude against the tenon, and providing means to prevent subsequent movement between the members.
Preferably, the movement prevention means includes providing on the inner surface of each limb a or a plurality of sharp protuberances which project therefrom, 2 and which protuberances of each limb engage and bite into the opposing surfaces of the corresponding tenon when the limbs are moved.
Preferably also, as the movement of each limb of a formation being pressed against a corresponding tenon side is or is being completed, a tongue is punched out of the limb into the tenon side.
Further according to a second aspect, the present invention is a building component comprising an inner structural member and an outer structural member, each structural member having one part of a two part fastening, the part on the inner member being a tenon, and the part on the outer member being a formation providing a mortise for location of the corresponding tenon, the formation being of channel shape having splayed apart limbs which are movable from a splayed attitude to a substantially parallel attitude against the side of the tenon, and means to prevent subsequent movement between the members.
Preferably, the movement preventing means includes a or a plurality of sharp probuberances projecting from the inner surface of each limb and the protuberances of each limb engaging and biting into the opposing surfaces of the tenon when the limbs are moved.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying schematic drawings, in which:
Fig. 1 is a cross-sectional view of a building component according to the present invention with fastening means in an open position; Fig. 2 is a cross-sectional view of an enlarged detail of the building component shown in Fig. 1; Fig. 3 is a cross-sectional view of the building'co: moOnentiwith.the fastening means in a closed position; Fig. 4 is a cross-sectional view of an enlarged detail of the building component shown in Fig. 3; 3 Figs. 5A and 5B are cross-sectional views of a building component showing respectively two types of thermal breaks provided in one structural member of the building component; Fig. 6 is a cross-sectional view of a modified building component, Fig. 7 is a cross-sectional view of an enlarged detail of the building component shown in Fig. 6; and Fig. 8 is a plan view of a length of a building component as shown in Fig. 5.
Referring to the drawings, a building component comprises an inner structural member 10 of non-temperature conducting material and an outer structural member 12 of metallic material. Each structural member 10, 12 is provided with one part of a two part fastening 14, 16. The part 14 of the inner structural member is a tenon, and the part 16 on the outer structural member 12 is a formation 18 providing a mortise for location of the corresponding tenon. The formation 18 is of channel shape having splayed apart limbs 20 on the inner surface of each of which means for preventing subsequent relative movement between the members is provided, the means being a plurality of sharp protuberances 22 which project from the limbs. With the tenon located in the mortise the two limbs 20 are brought together from a splayed attitude to a substantially parallel attitude against the tenon and in which the protuberances 22 of each limb 20 engage and bite into the opposing surfaces of the corresponding tenon. At the translation between the limbs 20 and a web 24 of the mortise, a groove 26 is provided to assist in the movement of the limbs 20. In Figs. 5A and 513, the outer member 12 is shown provided with a thermal break 30. In Fig. 5 A, the break is formed of two ties and in Fig. 5B the break is formed as a block. The ties and block are formed from synthetic plastics material.
In a first modification, as the movement of each limb 20 of a formation pressed against a corresponding tenon side is or is being completed, a tongue 28 is punched out of the limb 20 into the tenon side as a means of securing against 4 longitudinal movement of one member relative to the other. This tongue 28 is additional to the protuberances 22 in the movement prevention means or indeed can be an alternative to the protuberances.
In a second modification, only one protuberance can be provided on the 5 limbs, the shape of which differs as required.
In a third modification, the movement prevention means may simply be an adhesive bond between the members. This may be additional to one or other of the means described above.
In use, a building component as described is used to form a window frame to be installed with the metal outer structural members outermost. The advantages of the present invention are the combination of the good weathering characteristics of aluminium and the non-temperature conductivity of wood or plastic material on the interior of the frame.
Variations and other modifications can be made without departing from the scope of the invention described above and as claimed hereinafter.
