Description

FIELD OF THE INVENTION

The present invention relates to a construction. More particularly, the present invention relates to a building block for constructing a passage in a building for passing cables, pipes and the like.

BACKGROUND OF THE INVENTION

Generally, it is seen at many construction sites that channels are carved passing electrical wires, pipes or conduit by machine or manually which is time consuming and lot of labour is required. The channel generally is carved on wall, ceiling and floor of the house of the building and digging in pathways. Once, the finishing of the construction site is done and the channels are closed, thereafter it is very difficult to add any new cables, pipes and conduits wiring and carry out maintenance activity in case of any damages to the cables including electrical wires, internet cables, set top cables and the pipes including gas pipelines, water pipes or conduits. During maintenance, the wall, floor or pathways is drilled or dig again to open the channel to find out the damage, which creates lot of vibrations in the wall and may even lead to cracks in the wall floor or pathways. These vibrations may loosen the bond between the bricks of the wall. Also, refitting of the electrical wiring, pipes or conduit, in conventional type bricks is time consuming.

Till now, there is no such method or a system which can overcome the drawbacks of the present way of repairing or refitting of electrical wiring, pipes or conduit after construction of concealed walls.
