STRUCTURE DE MADRIER ET PROCEDE D'INSTALLATION

A PLANK STRUCTURE AND METHOD OF INSTALLATION

Abrégé français

L'invention concerne une structure qui comprend au moins un madrier (2) attaché par un côté à un bord d'au moins une solive (3) au moyen d'au moins un support (4). Le ou les supports comportent au moins deux premières ouvertures (7, 7'), à l'un ou l'autre côté du bord de la ou des solives, et au moins une autre ouverture (8) au-dessus dudit bord. La structure est rapide et aisée à assembler. L'assemblage est solide et durable et n'implique aucun risque de sécurité pour les utilisateurs. Il a également un aspect esthétique agréable et peut être fait de bois de feuillus.

Abrégé anglais

A structure is comprising at least one plank (2) attached with a side to an edge of at least one joist (3) by means of at least one mount (4). The at least one mount is with at least two first openings (7, 7') at either side of the edge of the at least one joist and at least one other opening (8) above said edge.

Description

CA 02671195 2009-06-01
The invention relates to a structure comprising t least one
plank with an underside attached generally trans ersely to a
topside of at least one joist, at least one ount placed
between said underside of the at least one pl k and said
topside of the at least one ioist, a base of the t least one
mount with at least one first attachment hol !, which is
communicating with the underside of the at least ob plank.,
,;.
Structures of this kind are widely used for exampl! for floors
in terraces, hoardings and pallets. ~
The Joist forms a bearing part of the structur`. It has a
relatively large height for being able to obtain tifie necessary
moment of resistance against being bent. The thic ess of the
joist may be smaller than the width of the planksi The planks
are norm1ly attached to the joists with a littl distance in
between.
Such structures have traditionally been assembled,by means of
nails or screws, which however can work up above t'e surface of
the plank-and cause a safety risk. The screws r nails can.
moreover be seen and detract from the aesthetic ppearance of
the structure and sometimes they also can discolo the area of
the structure surrounding the nails or screws.
~:.
in order to avoid these problems angular bracke s have been
used for. assembling the structures. The assembling:;operation by
means of such brackets is however difficult and tiuiI,e-consuming.
Mounts in form of plates with serrated edges are'wkl known and
can be used by being hammered into planks and ~oists to be
assembled. The obtained connections are however re!'atively week
and the operations difficult to carry out. Theseknown mounts
cannot be used when the structure is made of hard Wood.
