Floor Construction

[securespark]

I have been working 30 years in the electrical trade, but I have never seen this arrangement before.

Is it common?

When we run joists into oak beams we do similar but normally min 50mm bearing but looking at that may be a tusked tenon joint

Quite common on double floors in larger Victorian and Edwardian buildings such as banks, shops, large houses, mills and the like, I.e floors where there are primary beams running across the buildings connecting the walls, and where the joists themselves are let into the primary beams and the ends of the joists are also notched to fit into the sockets of the primary beams. That type of floor joist won't normally be connected to the primary beams with a tusked tenon (which in my experience are relatively uncommon) mainly because the primary beams are simply too big. You don't see these "cogged" joints in modern buildings - steels and the ubiquitous joist hangers have put an end to them

Thanks, guys.

This is my own house, the bedroom over the garage.

The house was built in 1960, the garage and this bedroom, 1970.

As I say, I have not seen this before.

Fairly unusual in a modern house, I'd say, but I have seen it of a few modern traditional oak framed buildings
