DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The present invention is illustrated in further details by the following non-limiting examples.

As illustrated in FIG. 1 of the appended drawings, a parapet wall structure 10 comprises posts 12 and heddles, such as upper and lower heddles 14 and 16 respectively.

As best seen in FIGS. 2 and 3, each post 12 is fastened to a siding of a building by a post fastening means 18.

The post fastening means 18 may be mounted to the siding of the building by a lag-bolt type of screw or by metal screws for example, depending on the material of the siding of the building, and to an edge of a roof 22, along a direction generally horizontal to a generally vertical direction of the siding of the building 20, by means of a mounting plate 24 (FIG. 8a).

The mounting plate 24 comprises a first part provided with apertures 26 for fastening to the edge of the roof 22, and a second part provided with slots 28 accommodating a foot of the post 12 (FIG. 6c). The mounting plate 24 may thus accommodate a range of thickness of the edge of the roof 22. Moreover, the mounting plate 24 secures the post 12 and prevents any movement of the post 12 down outward the siding of the building.

In the event the roof of the building has a dwarf wall or barrier built on an edge wall thereof, the post fastening means 18 may be fastened thereto by a barrier fastening means 30 shown in FIG. 7a. The barrier fastening means 30 comprises a first part 32, which engages a female part 36 of the post fastening means 18, and a second part 34, which is fastened on an interior or an exterior surface of the barrier, for example by means of screws 38.

A straightening clamp 40 may be used at the foot of the post 12 below the post fastening means 18 in the case when the post fastening means 18 is installed on a corner of a building for example (see FIGS. 2, 3 and 6). The straightening clamp 40 comprises a fixation plate 42 for fastening to the building siding, the fixation plate 42 supporting a threaded rod 44 (FIG. 6a). The straightening clamp 40 may thus press against the building siding, thereby further securing the post 12.

Embers 46, 48, shown for example in FIG. 8b, may be provided at each corner of the building (FIG. 1), and also at intervals along a side thereof, for example at every 10 posts 12, each ember connecting the building siding and a post 12. Embers fastening means 50 are illustrated in FIG. 9a.

The heddles 14 and 16 may be cables, connected to the posts 12 by self-equalizing anchor type sliding fastening means 52 shown in FIGS. 4 and 9c. Such self-equalizing anchor type sliding fastening means 52 may be provided at varied height along the post 12, where they are fastened by metal screws for example. Extremities of the cables are folded and secured in a cable clip 54 (FIGS. 4 and 8c).

In corners, as shown in FIG. 1, the cables 14 and 16 may be fastened to the posts 12 by corkscrew type rings 56 (see FIGS. 1 and 9b).

Although the present invention has been described hereinabove by way of embodiments thereof, it can be modified, without departing from the nature and teachings of the subject invention as defined in the appended claims.
