Description

TECHNICAL FIELD

The present disclosure relates to a lightweight construction element, in particular, to a lightweight construction element having a plurality of a web members spaced at a predetermined distance from each other. More specifically, the present disclosure relates to a lightweight construction element having two flange members spaced apart and coupled together with the plurality of web members.

BACKGROUND

Conventional construction element and framing members have been widely used as a part of a drywall system wherein the construction panels are connected to the conventional construction element. A plurality of the conventional construction elements are placed at a predetermined spacing such that the construction panels can be installed and affixed to the conventional construction element from one or both sides. Typically, a conventional construction element is comprised of a central region which is the web with a minimum of two flanges rising from either side of the web. Typically, the conventional construction elements are formed from one piece of metal and weigh about 1.4 kg to 1.6 kg per meter for a height of around 3.2 meter to 3.6 meter. It is significant to note that the manufacture of every single conventional construction element involves a huge quantity of metal consumption.

Over the years, there have been various developments in the configuration and structure of the conventional construction element leading to its design improvements. These design improvements include various attempts at structural modifications of the conventional construction element structure, targeted towards varied functionalities not limiting to sound insulation and thermal insulation among others. There has also been attempts at design improvements for reduction of metal consumption in the past. However, past changes in designing and technology in this space have not resulted in substantially less metal usage over that of a conventional construction element.

For example, in the prior art KR20130036982A, there is a structural modification made to the web of the stud such that the web is bent in a W-shaped format which thereby delays the noise and vibration transmission path. Further, some of the embodiments of this prior art, disclose a plurality of slots in the web for blocking a sound and vibration transmission path. However, the structural modification doesn't result in a substantial reduction in metal consumption or metal usage.

In yet another prior art WO2020125916A1, there has been a structural modification done in the web of the conventional construction element, which is a stud, aiming at the thermal decoupling of two limbs (or flanges). The webs in the prior art are in the form of plates which are fastened to a portion of the limbs. The structural modification so formed also results in reduced sound propagation. Still, there is no substantial reduction in metal usage of the stud and also the mode of connection of the web with the limbs could potentially result in disconnection of the joint during twisting and bending and thus resulting in the failure of the stud. In addition, it would be complex to manufacture and assemble the construction elements described in WO2020125916A1.

In the recent times, design improvements have also been targeted towards reduction in the weight of the stud, whereby skilled artisans explore means to reduce raw material consumption as a means of reducing the carbon footprint. It is well known that for construction and framing elements, each step of the manufacturing process (metal casting, metal forming, metal machining, metal joining, finishing and the related) involves a huge amount of CO₂ emission.

Hence, there have been attempts in the prior art to reduce the weight of the conventional construction element. However, the prior art design modifications have certain drawbacks which include complexity in manufacturing and handling, additional manufacturing operation requirement, weakening of the construction element such that it is incapable of resisting forces such as bending moments or even punching of metal parts which thereafter leads to metal wastage.

For example, as in the prior art WO2017015766A1, a conventional web in a stud is replaced by a wire matrix which in turn also provides passages for utility lines. Though the prior art results in reduction of the overall weight of the construction element, the arrangement of the web adds complexity and demands a technical expertise for installation, thus increasing the cost.

Further, the prior art KR101637145B1 describes a structural modification of the construction element, which is a stud, resulting in a lightweight partitioning stud. However, the complex arrangement makes the whole stud cumbersome to manufacture.

Thus, the known prior art references may result in reduction of metal usage and weight reduction of the construction element, but the solutions add complexity and difficulties to the manufacture of the products leading to increased manufacture and sale cost. Further, increased manufacturing complexity is likely to involve increased CO₂ emission, which will offset any CO₂ savings due to reduction in overall metal amount. Furthermore, there is no evidence in the prior art that the proposed lightweight construction elements do indeed result in decrement of CO₂ emission.

Thus, there is still need in the art to develop a construction element, addressing the shortcomings of the prior art mentioned above. In particular, there is a need in the art to develop a lightweight construction element that results in reduced CO₂ emission in the process of its manufacture and is simple and economical to manufacture.

Thus the present disclosure provides a lightweight construction element which eliminates the requirement of any additional manufacturing complexity, reduces the metal consumption and metal wastage and thereby results in a significant reduction in CO₂ emission. Most importantly, the present disclosure results in a lightweight construction element which has 25-40% lower weight as compared to any conventional construction element.

FIG. 1A is a perspective view of a lightweight construction element 100a in unassembled stage in accordance with one embodiment of the present disclosure. The lightweight construction element comprises a first and second flange member 10, 20 and a plurality of web members 50. The web members 50 each comprise a plate portion 51 with a length and a width, a first edge region 52a, a second edge region 52b, a third edge region 53a and a fourth edge region 53b. In the present embodiment, the web member 50 and plate portion 51 is one and the same. The first edge region 51a and the second edge region 52a lies across the width of the plate portion 51 and the third edge region 53a and the fourth edge 53b lies across the length of the plate portion 51. Further, the width of the plate portion 51 defines the spacing between the first flange member 10 and the second flange member 20. The first and second flange member 10, 20 each has front surface 13, 23 facing each other and a back surface 14, 24 non-facing each other. The first flange member 10 and the second flange member 20 are aligned alongside each other spaced at a distance X between the closest points on each flange member 10, 20. Further, the closest points for measuring distance X there between the flange members 10, 20 lies at their respective edges or at their respective centers or at respective points lying between their edges at their centers. Each of the flanges 10, 20 comprise a plurality of deformed regions such that each of the deformed region in the first flange 10 is aligned opposite and facing the deformed region in the second flange 20. The deformed region in the present embodiment shown in FIG. 1A comprises apertures 30a and 30b.

The lightweight construction element 100d and 100e is such that the first and second flange members 10, 20 are extended along their respective first edge 11, 21 and second edge 12, 22 at 90° to their respective front surfaces 13, 23 to form stiffener members 15, 25, respectively. In both the lightweight construction element 100d and 100e, stiffeners 15, 25 of the flange members 10, 20 further comprise slots 15′, 25′. The slots 15′, 25′ can be such that they are placed at a frequent interval with each other as depicted in FIG. 5A. In the present embodiment, the slots 15′, 25′ are spaced at an interval of 10-50 mm from each other. In some other embodiments, the slots 15′, 25′ are placed only at the areas wherein the web member 50 are to be coupled to the flange members 10, 20, as depicted in FIG. 5A. In the present embodiment, the slots 15′, 25′ are spaced at an interval of 100-500 mm from each other.
