Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority on a Canadian application
no 2,458,943 filed on Mar. 2, 2004. All documents above are herein
incorporated by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to a protection against
falling for works on elevated places such as an edge of a roof or
terrace. More specifically, the present invention is concerned with
a parapet wall structure.
BACKGROUND OF THE INVENTION
[0003] Parapet walls are structures used as protection against
falling for works on elevated places such as the edge of a roof or
terrace of a building and are nowadays required by law for workers
in the field.
[0004] Available parapet walls may be either fixed or removable
constructions.
[0005] There is still a need in the art for parapet walls ensuring
safety of workers, while being versatile in ease of installation
and of use in a number of settings and different geometry of a
building.
SUMMARY OF THE INVENTION
[0006] More specifically, there is provided a parapet wall
structure, comprising at least two posts, each post being fastened
to a siding of a building by a post fastening means; and at least
one heddle connected between two of the at least two posts; wherein
the post fastening means is fastened to the siding of the building
on the one hand and to an edge of a roof of the building on the
other hand, along a direction generally perpendicular to the siding
of the building, by a mounting plate including a first part
fastened to the edge of the roof and a second part accommodating a
foot of the post.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[0018] The present invention is illustrated in further details by
the following non-limiting examples.
[0019] 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.
[0020] 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.
[0021] 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).
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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).
[0027] 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).
[0028] 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.
