3. PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed:

TECHNICAL FIELD OF THE INVENTION
This invention relates generally to distribution boards used in electrical network. More particularly present invention relates to a rib cage assembly for distribution board enabling a minimum wall width.
BACKGROUND AND THE PRIOR ART
Distribution boards are very commonly used in electrical system. The wall on which distribution board is to be mounted usually has a wider wall thickness when compared to the rest of the walls in any civil constructions. The only reason for this extra thickness is to make sure the distribution board fits in the wall properly.
Generally the back surface of distribution boxes are flat and it is difficult to do masonry work as mortar (which is paste made of cement, water, and sand) cannot be held and falls down from flat surface during masonry work. To solve this problem people use higher wall thickness and put brick on the back of DBs. It leads to higher wall thickness of the specific wall where DB will be mounted.
The proposed invention enables the construction engineer to go with lower wall thickness specifically where they have constraint of distribution board fixing. It helps in saving a lot of civil material which goes in construction of wall thereby maintaining uniform width of the walls.

OBJECTS OF THE INVENTION
A basic object of the present invention is to overcome the disadvantages/drawbacks of the known art.
Another object of the present invention is to provide a rib-cage assembly enabling minimum wall width for flush mounted distribution board.
These and other advantages of the present invention will become readily apparent from the following detailed description read in conjunction with the accompanying drawings.
SUMMARY OF THE INVENTION
The following presents a simplified summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the present invention. It is not intended to identify the key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concept of the invention in a simplified form as a prelude to a more detailed description of the invention presented later.
There is provided A rib cage assembly for distribution boards.
According to one embodiment of the present invention, there is provided a rib cage assembly for distribution board enabling a

minimum wall width, said assembly comprising plurality of bars (7) having external ribs across entire length; plurality of panes (6); plurality of construction materials; wherein said rib cage assembly adapted to hold construction materials.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS
So that those having ordinary skill in the art will more readily understand how to construct a rib cage assembly for use in distribution boards in accordance with the present disclosure, exemplary embodiments are described in details herein below with reference the accompanying drawings wherein:
Fig. 1 illustrates the mounting of the rib-cage assembly in a wall.
Fig. 2 illustrates another view of rib cage assembly.
Fig. 3 illustrates detailed view of Rib Cage Assembly of the present invention.
Fig. 4 illustrates TMT bars and panes in absence of the Rib Cage Assembly.
DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS
The following drawings are illustrative of particular examples for enabling methods of the present invention, are descriptive of some of

the methods, and are not intended to limit the scope of the invention. The drawings are not to scale (unless so stated) and are intended for use in conjunction with the explanations in the following detailed description.
Reference is first invited to Fig 1 where the mounting of rib cage assembly on a wall is shown.
Fig. 2 shows another view of the mounting of rib cage.
Fig. 3 shows detailed view of rib cage assembly comprising bars and panes.
Fig. 4 shows TMT bars and panes in absence of the Rib Cage Assembly.
The invention therefore provides a rib cage assembly for distribution board enabling a minimum wall width.
DETAILED DESCRIPTION OF THE INVENTION
Accordingly in the present invention a rib-cage assembly (5) is provided which will be mounted onto the distribution board (3). The technical specifications and other assembly details are as following.
The rib-cage assembly is designed in such a way that it can hold the construction material. It is a mesh arrangement which has TMT bars (7) and panes (6)at an angle (15° to 45°) which helps in holding the

mortar or construction material (8). This rib-cage assembly is mounted behind the distribution board using screws.
The panes are at an angle so that it can hold the construction material from slipping thereby helping the board to get fixed in the wall. The TMT bars are used for better bonding purpose. The external ribs across the entire length of the TMT bar gives superior bonding strength between bar and the construction material. So by having this kind of arrangement the space for mounting in minimized, usage of material is minimized and increasing more carpet area.
Fig.1 & Fig.2 describes the mounting of the rib-cage assembly in a wall. Different components shown in figure are as follows:
1. Modular Devices
2. Wall (Front view)
3. Distribution board
4. Wall (Back view)
5. Rib-Cage
Fig. 3 describes detailed view of Rib Cage Assembly, which shows alternate TMT bars and panes. Fig. 4 shows that in absence of the Rib Cage Assembly, construction engineer need to have a brick work behind the distribution board to hold mortar. Rib Cage Assembly is self sufficient to hold mortar and therefore save wall thickness equivalent to the size and orientation of brick used behind the distribution board.

The rib-cage is being used for mounting on the distribution board which helps in holding the construction material thereby achieving minimum wall width where it is mounted. The construction material used can be concrete, mortar or any mass which is used for bonding purpose. The design of the rib-cage arrangement contains TMT bars and panes which are inclined at an angle approximately (15° to 45°).
Advantages:
• Use of proposed assembly with distribution board uniform wall thickness throughout home.
• It saves the civil material (Bricks, Mortar etc.) required for construction of the wall.
• More available carpet area in the building.
Although the embodiments herein are described with various specific embodiments, it will be obvious for a person skilled in the art to practice the embodiments herein with modifications. However, all such modifications are deemed to be within the scope of the claims.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the embodiments described herein and all the statements of the scope of the embodiments which as a matter of language might be said to fall there between.
