Abstract
A ridge unit for a building has two symmetrical components 1, 2 which contact at a line 14 along their lower edges. Each component has a back plate 4 from which project flanges 5, 6 for receiving a glazing bar 8, and another flange 11 which is received in a bracket 3 at the top of the components 1, 2. When the unit is in use, the weight from the glazing bars 8 causes a moment to be applied to the components 1, 2 about line 14, forcing their upper edge into side walls 13 of the bracket 3, giving rigidity. Other components for buildings are also disclosed, including a combined mullion and box section part which may be used to form corners and which may be slidable in tracks in other components. <IMAGE>
Description
SPECIFICATION
Building components
The present invention relates to components for buildings such as conservatories which are assembled on site from preshaped components. In general in such buildings, the components are metal (usually aluminium) extrusions which are cut to size and assembled to form a framework, and then other components such as doors, windows, etc. positioned in that framework.
Very often, however, the shape of the building desired imposes problems in the components to be used in forming the building. In particular, with many designs, the standard components cannot be used and components specifically for that design need to be manufactured, which is expensive. The present invention seeks to overcome this problem by providing building components which offer a wider range of configurations than the standard components available, and thereby simplify many building designs.
The present invention has a number of aspects relating to specific components. The first aspect of the present invention relates to a roof ridge unit, having two antisymmetrical side components for receiving glazing bars, which are held together in a "back to back" relationship at their upper edge by a bracket and which abut at their lower edge. The force of the glazing bars applies opposite moments to the two symmetric components, and the bracket prevents them from rotating or permits only limited rotation to a position in which the symmetric components are forced against the bracket. In this way, a very strong system is set up because the symmetrical components are braced by the weight of the surrounding structure against the bracket.The symmetrical components preferably consist of a back plate, from one side of which project two flanges for receiving glazing bars, and from the other side of which, at or adjacent one end which in use will be the upper end, projects another flange. The bracket fits around that latter flange, and around the adjacent parts of the back plate, thereby gripping it in a position where the end of the back plate of the two symmetric units remote from the bracket are in contact. It may also be noted that this symmetric component may then be used for another purpose, namely to attach glazing bars directly to a wall, by inserting the flange normally received by the bracket in a slot in the wall, with the back plate resting on the wall, so that a firm grip is achieved and no flashing needed.
The second aspect of the invention relates to the mullions of the building, i.e. the parts of the building on which the glass or other parts is to be supported. In existing designs, the mullions are simple extrusions and have little structural strength. The second aspect of the invention proposes joining a mullion part to a box section part to provide strength. The mullion may be designed to receive different inserts, depending on the object to be attached to the mullion. Preferably, the mullion part projects from the centre of one side of the box section, so that a symmetric component is obtained. Glass may then be attached to both sides of the mullion, or to only one side with the other side being squared-off, to make the component suitable for when e.g.
the box section is to be attached directly to a wall. It is also possible, using this construction to provide a corner of the framework at an angle other than 90". For hexagonal buildings, conventional designs have required special corner units, but by connecting together two of the mullion and box section units together by a suitably angled bracket, a strong corner can be obtained without difficulty.
The third aspect of the present invention relates to the connection of the components.
In the past, these have been simply bolted together, but the present invention proposes that tracks be provided in the units which receive corresponding projections on other of the units, so that the units may be slid into their correct place. Thus, increased flexibility in design is achieved. For example, the mullion and box section component described with respect to the second aspect of the present invention may have a projection at either end of the box section which is received in e.g.
horizontal sections such as the window sill. In this way the window sill may be cut to size on site, and then the mullion and box section component slid into the correct place.
Additional components may also be provided interacting with the above components to increase the flexibility of the design.
All the above components are preferably made from extrusion, e.g. of aluminium.
Embodiments of the present invention will now be described in detail, by way of example, with reference to the accompanying drawings, in which:

Fig. 8 shows an end unit for joining glazing bars to the component of Fig. 3.
Referring first to Fig. 1, a roof ridge unit is formed by two symmetrical components 1,2 attached together by a bracket 3. Each component has a back piece 4 from which project two substantially parallel flanges 5,6 for receiving one or more glazing bars 8. The flanges 5,6 are not perpendicular to the back plate 4, but are inclined by an angle which determines the angle of inclination of the glazing bars 8. As can be seen in the Figure, a projection 9 is provided on the upper flange 5, and an abutment block 10 provided on the back plate 4 adjacent the lower flange 6, so that the glazing bar 8 abuts against the projection 9 and the abutment block 10 (the glazing bar 8 does not abut against the back plate 4 due to the inclination of the flanges 5,6 to that back plate 4).At the upper end of the back plate 4 is a further flange 11 which projects in a direction generally opposite to the direction of projection of the flanges 5,6. The free end of this flange 11 is received in a slot formed by a projection 12 on the inner surface of the bracket 3, but is not tightly gripped thereby so that a certain amount of pivoting is possible. The junction of the back plate 4 and the flange 11 is received in a slot in a side wall 13 of the bracket 3, which side wall 13 preferably extends down so as to contact the upper flange 5 for receiving the glazing bar 8. As can be seen, the components 1,2, when gripped by the bracket 3' contact along a line 14 at their lower ends.
Thus, when the load of the glazing bars 8 is applied, the components 1,2 receive opposite moments about the line 14, forcing their upper corners into the side walls 13 of the bracket 3. In this way they are firmly braced by the bracket 3, and a strong construction is achieved.
Normally, the glazing bars 8 are inclined at an angle of 13 from the horizontal, and this determines the size of the bracket. If variation in this angle is needed, this could be achieved either by adjusting the angle of the flanges 5 and 6 to the back plate 4, or alternatively by adjusting thewidth of the bracket 3 so that the upper ends of the components 1,2 are further apart.
The component 1 or 2 of the ridge unit shown in Fig. 1 may have an alternative function. As shown in Fig. 2 the unit may be placed with the flange 11 received in a slot
15 in a wall 16. The back plate 4 rests against the wall and thus a sufficiently watertight seal is achieved to obviate the need of flashing. It can be seen that the glazing bars received by the flanges 5,6 will then be firmly braced to the wall 16.
The building component shown in Fig. 3 is a combined mullion and structural support. It may be used for any part of the building which is to support glass, including not only the vertical parts normally referred to as mullions, but also e.g. the inclined glazing bars 8.
The mullion part 20 projects from the centre of one side of a box section part 21 which provides structural strength. Since this component is formed by extrusion, the ends of the box section 21 would normally be open, but in practice they are sealed by end plates 22 having a projection 23 thereon, the purpose of which will be described later. The mullion part 20 has an upper bracket 24 and a lower bracket 25 for receiving other extrusions. In this way the component can be adapted to several purposes.
As illustrated in Fig. 3, a part 26 may be attached to one side of the mullion, permitting glass to be received in the gap 27 between that part and a projection 28 on a side of the box section 21. It would be possible to provide a similar part to that part 26 on the opposite side of the mullion 20 if the mullion was to form the join between two windows.
If, however, the box section 21 is to be attached directly to a wall, a terminating part 29 may be attached to one side of the mullion via the brackets 24 and 25, so that there is no gap between the mullion 20 and the wall.
This terminating part 29 may also be used to secure objects to the mullion, although for e.g. a door, a more elongate part corresponding to part 29 with the extension 29a shown in dot-dash lines may be needed. Thus, this design permits flexibility in that glass may be attached to either or both sides of the mullion part 20. In the past, separate components have had to be used depending on whether the mullion supported one or two windows.
A further use of the component of Fig. 3 is shown in Fig. 4. For buildings such as conservatories it is often desired for aesthetic reasons to have corners at other than right angles, e.g. to provide a hexagonal structure, and in the past this has been difficult to achieve economically. However, as shown in
Fig. 4, if two components 30,31 corresponding to the component shown in Fig. 3 are connected together by a corner component 32, a 60 corner can be achieved easily. The bracket 32 has flanges 33,34 which are received by the brackets 35,36 of the components 30,31 (those brackets corresponding to the brackets 24,25 in Fig. 3). The box sections of the components 30,31 give the corner great structural strength, and the bracket 32 ensures that the corner has a smooth outline. Furthermore, an end component 37 may be attached to the brackets 35,36 of the mullion part of the component 31, for e.g. attachment of a door to face 38 of bracket 37.
Again, therefore, great flexibility is achievable.
It was mentioned in connection with Fig. 3 that a projection 23 was provided on the end plate 22 of the box section 21 of that component. The purpose of this projection will now be described. Referring to Fig. 5, a component 40 corresponding to that shown in Fig. 3 is attached to another component such as a window sill 41 by that projection 23 which is received in a slot 42 in the window sill unit 41. In this way, the component 40 is firmly attached to the window sill 41, and yet can be moved laterally along the window sill unit 41 until the desired position is reached. In the past it has proved difficult to design buildings such as conservatories, because there are always slight variations between the plan size of the components and the size necessary when the building is assembled on site.As shown in Fig. 6, however, the use of slidable components permits two window sill units 43,44 to be attached together, and then the vertical components 40 slid in place along the slots 45,46 corresponding to the slot 42 in
Fig. 5.
In connection with this, the corner component 50 shown in Fig. 7 may also be used.
The corner unit 50 comprises two box sections joined together at one corner. The first box section comprises outer walls 51,52 and inner walls 53,54 which each have brackets 55,56 corresponding to the brackets 24,25 of the unit shown in Fig. 3. The second box section has two outer walls 57,58 having slots 59 therein corresponding to the slots 42 of the window sill unit 41 shown in Fig. 5 so that components such as that shown in Fig. 3 may be mounted onto the walls 57,58 can slide into place.
Fig. 8 shows another component, comprising a part 60 for joining one or more glazing bars 61 to one or more components 62 corresponding to that component shown in Fig.
3. The component 60 has a box section with one wall 64 having flanges 65,66 thereon for receiving the glazing bars 61, and a face 67 having a slot 68 therein for receiving a projection corresponding to the projection 23 on the component of Fig. 3. The component 60 may be provided with an additional flange 69 having brackets thereon for receiving corresponding brackets on a gutter unit 70.
Thus, by providing a relatively small number of components, it is possible to achieve a very strong framework for a building, which is easily adapted to the specific conditions in which the building is being constructed. Since the components such as Fig. 3 permit the replacement of several existing components by a single component, economy is achieved in the building construction, and this is further increased e.g. by the fact that some components may have more than one use. By making the components out of aluminium extrusion, relatively low cost can be achieved.
