Rooftop Electric Pipe Wiring Techniques
***************************************************************************************************
Pipes are installed on the roof in our country for concealed conduit wiring. And before installing this pipe, we have to install the points of the fanlight, etc., and wire the pipe. In this post, we will see what precautions should be taken to install this pipe.
1. Pipes for concealed wiring after binding the roof rod are likely to cause the roof to burst! If you want to do concealed wiring in the roof slab, you need to increase the thickness of the slab by technically calculating!
2. Many roofs are cracking due to a combination of modern-day building materials such as high-quality cement, high-grade rods, and weathering due to temperature rise!
3. If you put too much wiring pipe on the roof slab, its continuity and uniformity will suffer! As a result, the proportional difference between tensile and compressive elasticity will occur! It will be associated with the effect of weather temperature!
We know that the relative heat and elasticity of reinforcement (rod) and PVC pipe material are not the same! And it is very normal to crack due to the internal pressure caused in this way!
4. This type of crack can be seen after 3 months of roofing and can be seen even after 10 years!
5. Basically there is a need to put a pipe in the roof which is only for the fan. But electricians run all pipes through the roof to make connections from one wall to the opposite wall. As a result, the number of pipes on the roof increases! As a result of this hazard!
6. D.B. Near the box, where many pipes come together, the potential for danger is greatest. Due to bunched pipes, the crack starts at such places and then progresses along the pipe path. Which gradually leads to structural failure.
So what to do?
**********************
7. A single narrow pipe (any pipe narrower than half an inch is available) should be used for the fan point on the roof. This pipe will go from a wall to a fan hook. Place the pipe from one corner of the room to the fan point.
Do not put the pipe parallel to the beam! Will not go to the other wall. Never break the roof slab with a pipe!
8. Cut the wall with the remaining pipe machine and cross! If there is a column, do not cut the column!
9. Welding an additional 3 inches (without rod) on the lintel and pipe the concealed wiring through it is best!
10. In the case of the ground floor, you can pass the pipe through the rough casting of the floor!
11. In cases where there is no way but to put a pipe on the roof, in that case, not the roof slab, put the pipe through the beam! But place the pipe outside or through the covering zone, not through the rod cage (stirrup).
12. In case of a large span in column structure, do not lay pipes through load-bearing beams.
13. Do not lay any pipe on roofs with slabs that are 3 inches thick! And do not put any pipes on the last roof of the house.
14. After fitting the pipe to the wall, before plastering (rendering), take pictures of each wall! Later you will have a record of the direction of the concealed pipe when the wall leaks for various reasons! Don't accidentally drill the drill machine and leak the pipe!
15. Electricians or masons will convince you differently for the convenience of their work! For this, work under the supervision of an engineer.
16. When thinking about the roof's strength, the smartest thing to do is wire the capping casing! But this method is not spectacular!
