  • the spacing between the web member 50 was taken as 250mm and the total length of the flanges were taken as 3200mm.
  • three construction elements 100 were placed at an equidistant range of 600mm and fitted into the celling channel 110 and floor channel 120 at the top and bottom, respectively.
  • the ceiling channel 110 was fixed to the ceiling and the floor channel 120 was fixed to the floor (as illustrated in FIG. 6).
  • the lightweight construction element 100 results in 32% weight reduction as compared to a conventional construction element. Further, the resulting deflection in the lightweight construction element 100 in spite of having a spaced plurality of web members 50, retains the structural stability as that of the conventional construction element.
  • the increase in deflection of 2.9mm of the lightweight construction element 100 of the present disclosure can be overcome by 3% reduction in the height of the partition board. Further, the difference in partition board height also can be matched with conventional arrangement by adding an additional screw at the bottom between the construction element and floor channel interface.
  • the lightweight construction element 100a or 100b of the present disclosure is lightweight (in terms of eliminating the need of a continuous web) and results in reduction of CO2 emission during its manufacture.
  • the lightweight construction element 100a or 100b herein possesses the following advantages:
  • the lightweight construction element 100a or 100b of the present disclosure can be used in conjunction with currently existing industry standardized drywall components (viz. board for the drywall etc.) without necessitating a modification of other system components;
  • the plurality of web members 50 being spaced apart and having a gap in between consecutive web members results in light weight components and thereby results in ease of installation;
  • the lightweight construction element readily accommodates the use of mechanical fastening devices thereby eliminating deflection, bending or breakage of these devices due to any obstructions owing to its design;
  • the web members 50 are cut from flat metal sheets which thereby results in near to zero metal scrap and metal wastage.
  • the lightweight construction element 100a or 100b of the present disclosure finds application in building constructions not limiting to commercial and residential spaces.
  • the structural modification as in the present disclosure eliminates the usage of a continuous web to connect the flanges of a drywall lightweight construction element or channel component. It provides ease of manufacture, is sustainable, easy to transport and assemble and is also cost effective. Further, no additional assembly tools or accessories are required for the assembly of the web members in the lightweight construction element as described in the present disclosure.
  • the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a nonexclusive inclusion.
  • a method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such method, article, or apparatus.
  • “or” refers to an inclusive-or and not to an exclusive-or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

Abstract

L'invention concerne un élément de construction léger comprenant un premier et un deuxième élément formant bride (10, 20) ayant chacun une face avant (13, 23) se faisant face l'une l'autre et une face arrière (14, 24) opposées l'une à l'autre. Le premier élément de bride et le deuxième élément formant bride (10, 20) sont alignés les uns à côté des autres à une distance X. En outre, l'élément de construction léger comprend une pluralité de membrures d'âme (50), moyennant quoi la longueur de la portion de plaque (51) des membrures d'âme 50) définit l'espacement entre le premier élément formant bride (10) et le deuxième élément formant bride (20). La pluralité de membrures d'âme (50) sont couplées physiquement aux premier et deuxième éléments formant bride (10, 20) par fixation soit à la surface avant (13, 23), soit à la surface arrière (14, 24) de chaque élément formant bride (10, 20), et sont pliés selon un angle compris entre 90 et 110 degrés par rapport à la portion de plaque (51) le long de la ligne de fixation (60). La pluralité d'éléments de bande 50 élimine le besoin d'une bande pleine longueur et conduit à une réduction de l'utilisation de métal et donc à son tour à une réduction des émissions de CO2.
