Description

CA 02220~69 1997-11-10 WO 96t35848 PCT/GB96101124 BUII nlNG COMPONENT

This invention relates to a building component for use in constructing a roof for a building primarily, but not only, a building constructed having a "double skin" outer wall(s) particularly, but not necessarily, having a cavity between said skins, the cavity normally being filled or substantially so with an5 insulation material. A requirement of building regulations currently in force is the capping or closing-off of the top of such cavity. This capping operation is normally achieved by fabrication on site using a board of natural or synthetic material in the same, a preceding or a succee~ing operation including a gable wall overhang, a barge board and a sofft. While this invention is primarily 0 concerned with the provision of gable wall overhangs, barge boards and soffits, it is also applicable to the provision of fronVrear wall overhangs, fascia boards and soffits. Heretofore, oveil,angs have been constructed of timber as have barge boards and soffits which require regular painting maintenance with both barge boards and soffts being susceptible to rot and decay and requiring 15 periodic replacement. Barge boards and soffits have also been provided of synthetic plastics material. While these are beneficial in requiring little maintenance they tend to degrade when exposed to sunlight, due to ultra violet radiation and thermal stresses. These existing building components are disadvantageous and an object of the present invention is to obviate or 20 mitigate these disadvantages.
Accordingly, the present invention is a building component comprising a block unit having a capping portion and an overhang portion, the outer face of CA 02220~69 1997-11-10 the overhang portion being to serve as a barge/fascia board. A lower face of the overhang portion beneficially serves as a soffit.
The block unit is desirably for use with others ol its kind in being laid side-by-side as a course on top of a wall. Alternatively, a multi-block unit maybe provided of desired length for use with others of its kind. The capping portion of the block unit is of tile shape, in a first embodiment, to be positioned over a double-skinned wall and, in a second embodiment, is shaped to be positioned over and straddle the outer skin of the wall. In both embodiments, the overhang portion projects outwardly beyond the wall.
o The capping portion is preferably of equal weight to or heavier than theoverhang portion to counterbalance or overbalance inwardly the block unit when laid on a wall or the outer skin thereof.
Preferably, the block unit is made of any durabie material, for example cementitious material. The overhang portion is beneficially hollow or may have 15 multi-cavities therein, or may be cellular. The block unit may alternatively be cast from two cementitious mixtures, one containing a stone agyr~:gdle in respect of the capping portion, and the other containing a light-weight aggregate in t~:s~e.il of the overhang portion which is solid.
Embodiments of the present invention will now be described, by way of 20 example, with reference to the accompanying drawings, in which:-Fig. 1 is a perspective view of a part of a top and one gable of a building showing a roof support structure with a gable overhang, a barge board and a soffit constructed conventionally;
Fig. 2A is a perspective view of a part of a top and one end of a building 25 showing a roof support structure with a course of block units according to a first embodiment of the present invention; overlying the top of a gable wall;

-CA 02220~69 1997-11-10 Fig. 2B is a perspective view of a part of a top and one end of a building showing a roof support structure with a course of block units according to a second embodiment, overlying both the top of a gable wall and a front wall;
Figs. 3A and 3B are similar perspective views of a block unit according to a first embodiment showing different shaped hollow configurations provided in an overhang portion thereof;
Figs. 4A and 4B are respectively, a perspective view and a side elevational view of a modified block unit according to the first embodiment;
Figs. 5A and 5B are respectively, a perspective view and a side o elevational view of a block unit according to a second embodiment; and Figs. 6A and 6B are respectively, a perspective view and a side elevational view of a modified block unit accordi, lg to a second embodiment having a baK of insulation material secured to the inner end of the block unit.
Referring to the drawings, a building component cor"~Jrises a block unH
8, 8' having a capping portion 10 /10' and an overhang portion 12 with the outer face of portion 12 serving as a barge or fascia board 14A and a lower face as a soffit 14B.
The block unit 8, 8' is for use with others of its kind in being laid side-by-side as a course on top of a double-skinned wall 16 with the capping portion 20 10 thereon and the overhang portion 12 projecting outwardly beyond the outer skin of the wall 16.
The capping portion 10 is of equal weight to or heavier than the overhang portion 12 to counterbalance or overbalance inwardly the block unit 8, 8' when laid on a gable wall 16.
The block unit 8, 8' is made of any durable material, for example cementitious material, and can be coloured to suit a particular colour scheme for the rest of the normally painted or coloured parts of a building, for example CA 02220~69 1997-11-10 window frames, guttering or doors. The overhang por~ion 12 is hollow as shown in Figs. 3A or 3B, 4A or 4B, 5A or 5B, 6A or 6B with a cylindrical tubularfommed passage as shown in Fig. 3A or square tubular formed passage as shown in Figs. 3B, 4A, 4B, 5A, 5B, 6A and 6B. Comer or end block units 18 are provided to terminate a course of block units 8, 8~as shown in Figs. 2A and 2B laid on top of the gable wall or front wall 17 in the same manner as conventional bricks or blocks are laid using mortar. An apex 20 may be formed by providing mitre sides to the block units 8, 8' to be abutting at the vertex of the wall. The top surfaces of the block units 8, 8' are flush with the top surfaces of a series of rafters 22 on the gable wall which rafters 22 together provide a roof support structure for a tiled or slated roof including battens and felt/underlay covering.
The outer face of the overhang portions 12 when being moulded may be provided with a wood grain or other omamental/decorc~ /e effect.
~s A gable overhang and barge board when formed in the manner described above is beneficial over the existing provision for such and requires little or no maintenance.
In a first embodiment, the capping portion 10 of the block unit 8 overlies both skins and closes offthe cavity between both skins in the gable wall 16.
In a second embodiment, the capping portion 1~' of the block unit 8' overlies horizontally the outer skin of any outer wall and terminates with a downwardly extending leg portion 9 at right angles thereto, the capping portion 10' straddling the outer skin with leg portion 9 closing off the top of the cavity between the double skins of the wall.
Although the invention has been described in a~nnection with pitched gable walls, the building component can equally be used with gable walls 16 of CA 02220~69 l997-ll-lO

s flat-roofed structures and with front and rear walls 17 of pitched gable or flat-roofed structures.
As shown in Figs. 4A and 4B, the modified block unit of the first embodiment is provided with a drip channel 24 adjacent to the outer edge of 5 soffit 14B, and a marked or recessed panel 26 is provided in the top face of the capping portion 10 as an indicator for the positioning of a restraining element in the form of a wooden batten (not shown) or the like forming part of a roof structure.
