Abstract

A building construction including a supporting structure (20) carrying cladding panels (10) is provided with a corner edging member (30, 30a) at the junction of adjacent walls or at the junction between a wall and a roof structure. The edging member (30) is secured to the supporting structure by means of fastenings (23) disposed within a recess (34) in which the margin of a cladding panel is securely received without additional fasteners. The recess may be defined by a marginal part of the edging member in combination with an adjacent part of the supporting structure, or by a marginal part of the edging member alone. <IMAGE>

Description

SPECIFICATION Building construction This invention relates to the construction of buildings of the type wherein wall and/or roof structures include cladding panels secured to an appropriate support structure.

For both aesthetic and practical reasons it is desirable for fastenings used to secure such panels to the support structure to be concealed. Additionally, some form of edging is required at corners, such as at the junction between adjacent walls or at the junction between a wall and a roof structure, to mask and protect the edges of panels that would otherwise be exposed at such corners, and again it is desirable to conceal fastenings used to attach such edging.

Generally, for these purposes, plugs or closure strips are used which are designed to fit into specially shaped recesses afforded by the panels or edging, but nevertheless it can be difficult to fit these securely.

The present invention resides in a construction including an edging member which is secured to a support structure and, at least in combination with the latter, defines at least one longitudinal recess for the secure reception of the marginal portion of a cladding panel without the use of additional fastenings, the edging member itself being secured to the support structure by fastenings located within said recess.

The invention is particularly suitable for use with edging members to be provided at the corner defined by the junction of two walls or at the corner defined by the junction of a wall and a roof structure.

Whilst, in most previous systems an edging member provided at such corners is secured to, and supported by, the adjacent cladding panels, the latter being securely fastened to the support structure at a position immediately adjacent to the edging member, in accordance with the present invention, it is the edging members which are fixed securely to the support structure and in turn serve to secure the adjacent margins of the cladding panels.

Thus, in accordance with one aspect of the invention, an edging member comprises a main longitudinal portion having its opposed lateral margins disposed in mutually transverse relationship, at least one of said margins affording a flange extending transversely relative to the adjacent part of the member and spaced inwardly from the free edge thereof so as to define, at least in part, said recess for the reception of the marginal portion of a cladding panel. In use, such flange may be fastened to a corresponding flange afforded by the supporting structure of the building.

Conveniently, said flange may be formed by folding an edge portion of the edging Member back upon itself and folding the margin thereof transversely. Alternatively, the edging member may be formed as an extrusion or in some other comparable manner.

Both margins of the edging member may be of similar configuration, or alternatively only one margin may afford said recess. In the latter case, the edging member may particularly be used at the corner formed at the junction of a wall and a roof structure.

The main longitudinal portion of the edging member is preferably curved to afford a smooth transition between its lateral margins, although an angled section could be employed if desired.

The invention will now be described by way of example with reference to the accompanying drawings, wherein: Figure 1 shows a fragmentary transverse section in a horizontal plane of a corner contruction between two adjacent walls; and Figure 2 shows a fragmentary transverse section in a vertical plane through a corner at the eaves of a building between a wall and the roof structure.

As shown in Fig. 1, two adjacent walls of a building are provided with external cladding panels 10 carried by a supporting structure indicated generally at 20. The panels 10 may comprise metal sheets of flat or corrugated form, or with trapezoidal or box-rib profiles.

The panels 10 may include suitable thermally insulating material, but the precise form of the panels is not relevant to the present invention.

The supporting structure 20 typically comprises transverse members 21 which support angle section uprights 22. Conventionally, panels 10 are secured to the transverse members 21 by means of appropriate fastenings, and it is to be understood that the illustrated panels 10 are secured to the supporting structure 20 in such conventional manner at the vertical margins (not shown) remote from the corner.

However, in accordance with the invention, the corner construction includes an edging, or corner, member 30 which may be formed from folded sheet material, or as an extrusion or moulding. The member 30 includes a smoothly curved main portion 31 which defines a radiused corner, with inturned marginal portions 32 which lie substantially in face to-face relation with the curved portion 31 at the lateral margins thereof. The free margins of the inturned portions 32 extend transversely to form flanges 33 which are assembled in face-to-face relation with one limb of respective upright members 22 of the support structure 20, and secured thereto by means of suitable fastenings 23.

As can be seen, the inturned portions 32 of the corner member 30 are disposed in spaced parallel relation to opposed parts of the supporting structure 20, in this case afforded by a limb of the upright member 22, so as to define a recess 34 into which a vertical marginal portion of the panel 10 can be introduced.

The recess 34 is so dimensioned as to receive the marginal portion of the panel 10 and hold the latter securely without the need for additional fastening elements.

It will be observed that the fastenings 23 whereby the corner member 30 is secured to the supporting structure 20 are themselves located within such recesses and are therefore concealed and protected by the panels 10.

Referring now to Fig. 2, the arrangement at the eaves of the building is generally similar, but employs a modified edging, or eaves, member 30a which has a transverse flange 33a afforded by an inturned portion 32a at only one lateral margin thereof, to receive the upper edge of a wall panel 10. The opposite margin of the eaves member 30a may be formed in any suitable manner according to the requirements in any particular type of construction. For example, as shown, such margin may afford a double thickness transverse flange 35 which is secured to a part of the support structure by means of a fastener indicated at 36, which also serves to secure a gutter member 37 in position, but many other arrangements are possible.

Whilst the edging members illustrated are of smoothly curved section, it will be appreciated that they could be formed to any desired shape, including in particular angled sections.

Also, whilst the recess for the reception of a marginal portion of the cladding panels is effectively defined by the illustrated edging members in combination with the support structure, it would alternatively be possible for such recesses to be defined entirely by the edging members. For example, a continuation of the flanges 33 could extend in spaced parallel relationship to the inturned portion 32, with the advantage that this would allow greater tolerance with regard to the location of the flange 3 relative to the support structure.
