build in a 190 cm wide window and wood frame
I have been tasked (by my wife) to install a fixed window between the sink and kitchen cabinet. The window is 190 cm wide and 40 cm high. Since I have a wooden frame, I know that I need to cut out 3 studs (cc 60) on the eave side to install a supporting frame for the window. The roof is a standard truss construction, vaulted without an upper floor, and with concrete tiles. How thick and what material (wood/steel) should the frame be inside the wall, around the window frames to withstand the pressure from the cut studs?
I own a concrete pumping company and saw such a wide window installed at a customer's house where I was working, and that's where the idea was born. I'm beginning to regret now that I promised my wife that Friday night after a few beers that we would have a bright kitchen.
Is there anyone here on the forum who understands the structural mechanics of wood-framed houses?

Now, I am not educated in structural mechanics, but there are various calculation programs online, such as http://www.byggbeskrivningar.se/ where there is a dimensioning program, Moelven has one http://www.iat.inadire.se/WebLagerbalk/Lagerbalk.aspx. Remember that when making alterations to a load-bearing structure, you need to report this to the municipality.
You should probably talk to a structural engineer about that. But I can mention that I did a beam over a 3-meter windowed doorway and it was calculated that a glulam beam 56x225mm was more than sufficient. It costs only a few hundred at Bauhaus or Byggmax. I now have a metal roof, so I assume the weight for your part is higher, but you probably won't need a steel beam. Talk to an engineer if you can.

Why not 3 windows between the posts?

I've already had that discussion with my wife, and she's the one who decides at home.....prototypen said:
No, I actually agree with her, it will look nicer with a wide window. It should also be noted that I'm not afraid to undertake complicated building projects that are physically and mentally demanding. I work with pumping concrete, so hassle and problems are everyday matters for me. Building in a window is not particularly troublesome, I just want to know the dimensions needed for adequate load-bearing capacity.
Where I live it's like High Chaparral with extensions - none of my neighbors have ever applied for or reported anything to the municipality about their building projects. I'm probably the biggest coward out here, with my measly 6 m2 too much. One neighbor has a "friggebod" with 3 rooms and a kitchen, which he rents out. You can guess for yourself if he declares those incomes!Ola78 said:Now, I'm not trained in structural engineering, but there are some different calculation programs online, for example at [link] where there is a dimensioning program, Moelven has one [link]. Don't forget that when you make changes to a load-bearing structure, you must notify the municipality with a building notification.
High Chaparal rules
it was good. The neighbors in the quiet residential area who, after a few beers on Saturday, put on cowboy hats and fight against the authorities
That part about a building notification was just a little information, at least you have your back covered then.
I understand you mean well!Ola78 said:
I have the luxury of living in an area where all the neighbors greet each other and help each other with building projects without jealousy and fuss if a neighbor builds a 300 m2 terrace (of course without a building permit) or if another neighbor builds a garage (30 m2 more than allowed, the entire construction without a building permit) and with a furnished upper floor. According to the property taxation, everyone in the area has: outhouse, no triple-glazed windows (and only 4 windows/house), no underfloor heating, no insulation in the walls, no parquet, no upper floor, no garage... etc...
One can have moral opinions on that mentality, but I, too, can have moral opinions in society, we just want to avoid paying money for something where no one knows where the money goes.
Yes, it was not a critique towards you. Personally, I don't really care what people do with their houses and gardens, what the municipality doesn't know won't bother them. There are better things to care about. So according to your property assessments, you live in houses that haven't changed since the '30s
then our renovation project is really modern, measured by that yardstick
Good luck with the window^_^b

I vote that you make the relief as high as possible so the window frame doesn't need to interact with the construction, as wood is a living material, and the pane shouldn't have to crack. If you have access to a rip saw, you can manufacture your own laminated wood for the window frame itself. Sounds like a fun project. Good luck!
I'm considering taking a chance! Either I build for elephants, or I build for ants. I haven't opened up the interior wall yet, but I expect to have 45 x 145 studs, which means I can fit 3 pieces of 220 x 45 studs in width, which will form the frame around the window bay in the wall. 3 pieces of 220 x 45 studs in width with a span of 2 m will definitely hold up a substantial car. I find it hard to imagine that just those 3 studs I'm making a recess on would be loaded with 2 tons, even with 1 m of snow on the roof.Apprentice said:I vote that you make the demarcation as high as possible so the window frame doesn't need to interact with the construction, as wood is a living material and the pane shouldn't need to crack.

A few years ago, I loaded my 4-axle Volvo FM Globe (Sarakas narrow tank) with 9.5 m3 of concrete (slightly overloaded, gross weight: 37 tons) and was going to deliver to a customer in the archipelago. The customer hadn't specified that there was a 6 m long wooden bridge to his residential area (apart from the final stretch being a BK3 road). You don't want to be in a concrete truck weighing 37 tons on a BK3 road and having crashed through a wooden bridge when the police arrive at the accident scene! Then the problems get considerably worse!!! But, "loaded load delivered to customer regardless...". I was curious if the bridge would hold - and it did - but it creaked quite a bit, yet it held, and it is based on this principle that I will build the window frame, which will be just a bit weaker than the wooden bridge.
If any children are reading this: Do not drive a 37-ton concrete truck over a wooden bridge on a BK3 road! Mom and dad will get mad then.
