I dug a hole in the beam. Please help me find out if this is the main beam?

Dear! It's fine. We often encounter this kind of thing when decorating, and it's absolutely fine.

Drill a hole in the beam. I don’t know whether it is a main beam or a secondary beam.

Window beams should be secondary beams. If you have to drill holes, it is best to use a thicker impact drill, which can move when encountering steel bars, but with a water drill, the steel bars will be broken. The drilled part is in the middle of the height of the beam, close to the edge of the beam, even if it encounters steel bars, it is also a stirrup. The main reinforcements are at the bottom of the beam. The spacing between holes should be larger, as it would be detrimental to the beam if they are concentrated.

The problem of drilling holes in beams

My old father has been doing decoration for almost half his life. Regarding the problem of drilling holes in beams, I would like to give you a suggestion. First check whether the beam is If it is the main beam, you should not open more than 2 holes, and the diameter should not exceed 4-7 cm.

At the intersection of the primary and secondary beams, the primary beam is the support of the secondary beam, so the support reinforcement is not...

Yes! The main beam is equivalent to a column! The negative reinforcement of the support on the secondary beam that is 1/3 of the clear span bears the bending moment! The main beam is equipped with bent steel bars and reinforced steel reinforcement areas, where the shear force is very large. When the torque on the main beam is large enough, torsion reinforcement should be provided. If you understand the force, it will be ok

Does drilling holes in beams affect Feng Shui?

Feng Shui is not a good idea if the beam itself is not good in Feng Shui. Do not use beams to press the ceiling. Decoration is usually done with suspended ceilings. Hidden, but the most important thing is safety. If the main beam is drilled and the tendons are damaged, there will be hidden dangers to safety. It is not a problem of Feng Shui.

I would like to ask all the technical masters: at the end of the overhang, when the main beam and the secondary beam intersect ...

There are pictures on pages 2-33 of the 06G901-1 atlas that explain in detail the method of primary and secondary beams. Generally, the secondary beam is placed on the main beam. At the cantilever end, the cantilever beam is the main beam, and the non-cantilever steel bars should be pressed on the cantilever beam. Hope this helps you
