Benefits of technology

[0009] In one aspect, the preferred embodiments of the present invention provide an eave lining sheet which is pre-finished on at least one exposed surface prior to installation on building structure. The at least one pre-finished surface comprises a layer selected from the group consisting of paint, coating, and laminate. In one embodiment, the sheet is pre-finished by the use of pigmented base materials and / or additives such that minimal further finishing is required. In another embodiment, the eave lining sheet comprises a release liner positioned adjacent to the exposed surface so as to protect the pre-finished surface from damage.
[0011] In another embodiment, the system further includes a pre-finished corner trim system for concealing and finishing a joint area between the eave lining sheet and an adjacent building surface. Preferably, the trim system is a two-part system comprising an inner core element that is adapted to be secured to the support surface or the adjacent building surface, and an outer pre-finished clip-on cover element. In one embodiment, the cover element comprises standard straight length sections and custom pre-formed corner pieces. The corner pieces are preferably positioned over at least a portion of the straight length section to allow for expansion and reduce the need for accurate length cuts on the sections. The inner core trim element can be solid or hollow and has a shape selected from the group consisting of rectangular, quad, and fillet profile, wherein rebates are formed adjacent diametrically opposed corner edges for accepting in-turned lip portions on corresponding outer trim cover portions having a similar general profile as the exposed portion of the inner core element. In one embodiment, the rebates are preferably formed on all edges or multiple sets of corner edges of the trim element.

Problems solved by technology

These finishing processes after installation add greatly to the expense of installing eave linings.
The labor, paint and setting costs as well as additional time taken to paint and / or set the eaves all add to the installation cost.
Moreover, eaves are most often situated high up on building structures and therefore, the installation would incur additional costs for scaffolding equipment to elevate the tradesmen during the eave finishing and painting process.
This is a particular problem in the construction of many project, kit and pre-finished buildings where the only parts of the entire building requiring painting are the eaves.
Another problem is the consistency of the painting when done onsite.
It is often the case that the coverage applied by hand painting eaves is not uniformly thick.
This may result in patchy protection and / or appearance.
Similar problems also apply in relation to the setting and concealing of various joints where this is required.

Embodiment Construction

[0033] The preferred embodiments of the invention will be described predominantly in the context of installation of eave linings. It will be appreciated, however, that the invention is not limited to this particular field of use, being also applicable to other areas of building and construction.

[0034] In general terms, certain preferred embodiments of the present invention provide a pre-finished eave system for buildings such that no additional painting or finishing of the eaves is required after installation. The pre-finished eave system generally includes a pre-finished eave lining sheet and a securing member for attaching the sheet to a building structure.

[0035] In one embodiment, the eave lining sheets are made of fiber reinforced cement (FRC), for example those classified as Type A Category 3 in accordance with AS / NZS 2908.2 ‘Cellulose-Cement Products’. However, in alternative embodiments, the sheets may be of other suitable materials. For example, it will be appreciated that...

Abstract

An eave lining system for buildings including an eave lining sheet pre-finished on at least one exposed surface and securing means for affixing the eave sheet to a support surface is provided. The eave sheet and securing means are configured such that minimal post installation finishing is required. In a preferred form, the system includes a pre-finished corner trim system for concealing and finishing the joint between the eave lining sheet and the adjacent building surface. The trim system can be a two-part system including an inner core element that is secured to the eave support structure or adjacent building surface, and an outer pre-finished clip on cover element. The cover element can be made of standard straight length sections and custom pre-formed corner pieces that sit over the ends of the straight sections.

Description

RELATED APPLICATIONS [0001] This application claims priority to Australian Provisional Application No. 2003906615, filed Nov. 28, 2003, and Australian Provisional Application No. 2004903302, filed Jun. 17, 2004, and Australian Provisional Application No. 2004903567, filed Jun. 29, 2004, the entirety of each of which is hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to building construction, and more particularly to eave lining systems for building structures and installation of the same. [0004] 2. Description of the Related Art [0005] In the construction industry, the installation of eave linings is typically a multi-stage process. Eave sheet used to line the eaves is generally produced in set lengths and widths. The sheet must be transported to site, nailed into position on the building. The joint sections are typically set, concealed or connected using joining strips. A finish is then ap...
